stored MAF Trimming Factor from ECU Production Line as ratio between measured and nominal voltage
Input data:
In order to compensate the Voltage Tolerance of the ECU internal Reference Voltage Supply
which is used to evaluate the MAF Sensor Signal Input, a Trimming Value is determined
during the ECU Production Process at the Manufacturing End-of-Line Test.
A nominal Trimming Voltage C_V_MAF_TRIM_NOM (typically 4.000 V) is applied from an
external Precision Device to the ECU MAF Signal Input and then measured inside the ECU.
The MAF-Signal Voltage inside the ECU is measured 10 times and then averaged. The
averaged Value is stored in the non-volatile Memory and used to calculate the Trimming
Value as Ratio between the measured Voltage and the nominal Voltage.
The Trimming Value is limited to +/- 10 % (FAC_MAF_TRIM = 0.9 … 1.1).
Measured Values which are outside the allowed tolerance window indicate a too high ECU
Hardware Tolerance or a wrongly adjusted nominal Voltage and reject the ECU from the
Production Line for Rework.
The Trimming Value is determined only once in the ECU Lifetime during the VXI Test.
As the Trimming Value is unique to the ECU hardware, it is never overwritten or erased.
For Testing Purpose it is possible to switch from the trimmed value to the init value by a
calibration constant. The trimmed value remains in the memory, but the read-out correction
value is then changed to the initialization values.

Application conditions:
Initialisation: the Initialization is performed only when no Trimming was done before
or the Trimming has been reset by LC_RST_MAF_TRIM for testing.
If LV_MAF_TRIM = 0 from NVMY (no Trimming Values available)
then
if STATE_MAF_TRIM = 00 h (read from Address 6000h…6001h)
(to check if MAF Trimming was done at ECU Production Line)
and MAF Trimming Value from Address 6002h…6005h is valid
then V_MAF_TRIM = saved value from Address 6002h…6005h
FAC_MAF_TRIM = V_MAF_TRIM / C_V_MAF_TRIM_NOM
(calculation of Trimming Factor from saved Trimming Value)
LV_MAF_TRIM = 1 (to indicate that Trimming is available)
else V_MAF_TRIM = C_V_MAF_TRIM_NOM
FAC_MAF_TRIM = 1 (to apply neutral init values)
else (Trimming Values are available)

FAC_MAF_TRIM = FAC_MAF_TRIM from NVMY

Reset of the Trimming Values for Testing Purpose:

If LC_RST_MAF_TRIM = 1 (Reset of Trimming Value requested)

Input data:
BIOS_RST_GET_STATUS BIOS_RST_IS_STATUS_VALID
In order to support the root-cause identification after a non-power-on ECU Reset, the
available background information from I/O Software is read out and stored to the non-volatile
memory. The stored information is only written or overwritten by unexpected resets.
The BIOS driver for the Reset provides a basic interface BIOS_RST_GET_STATUS which
describes the status of processor reset unit and cause of ECU reset, if one occurs.
There are two groups of possible reset causes:
- SW-caused resets (described by ECU_RST_STATUS_SW_1/2)
- HW-caused resets (described by ECU_RST_STATUS_HW)
Formula section:
Activation: once after any Reset

Deactivation: 1. when ECU is reset through KWP service request, ECU RESET
2. when Reprogramming Session gets started
If BIOS_RST_IS_STATUS_VALID (to determine non-power-on Reset)
then write data from BIOS_RST_GET_STATUS
into ECU_RST_STATUS_SW_1
and ECU_RST_STATUS_SW_2
and ECU_RST_STATUS_HW

The adaptation values can be erased in several ways:

- via KW2000-protocol
- after battery disconnection detected

- with application system by calibration
The adaptation values can be erased in SAM2000 by the calibration constant LC_AD_CLR
(all adaptation values) or by the calibrations LC_AD_CLR_xxx (individual adaptation values).
The Reset is effective immediately and only at the transition from LC_AD_CLR(_xxx)= 0 to 1.

Note : additionally to the erasement of adpatation values, an erasement of the failure

memory can be performed. More informatino available in chapter A.
Application recurrence: once after system reset.

0.6.1 Erasement after battery disconnection

A hardware with one bit-memory characteristic is provided which detects at system start up if
the ECU or the battery was disconnected since the last housekeeping phase.
If a disconnection is configured and detected, and erasement of non volatile memory is
configured the adaptation values will be reset like described below.
Formula section:
Detection of battery-off :
If CONF_FMY_RST = 1
or CONF_AD_RST > 0
then LV_VB_OFF_ACT = LV_VB_OFF (One-Bit Memory is set)
else LV_VB_OFF_ACT = 0 (reset One-Bit Memory)
Remark : The flag LV_VB_OFF is set to 1 if the battery has been disconnected since
the last driving cycle : LV_VB_OFF = LV_IM_VB_OFF
Erasement of failure memory:

If LV_VB_OFF = 1
then If CONF_FMY_RST = 0 then the failure memory is not reset
If CONF_FMY_RST = 1 then the failure memory is reset
Erasement of adaptative values from the memory :
If LV_VB_OFF = 1
then If CONF_AD_RST = 0 then the adaptation values are not reset
If CONF_AD_RST = 1 then all the adaptation values are reset
If CONF_AD_RST = 2 then only some adaptation values are reset. See
details in the table below.
Remark : After the first power latch phase after battery disconnection, it takes at least 50 ms
until the One-Bit Memory is reset.

Flag indicating Block restored has already been read NC_MAX_RD_AR_NVMY times
The saving of datas to the Non Volatile Memory is only allowed at the end of Power latch
before ECU switch off. The area for saved data is made of several blocks. At the end of the
Power latch data are stored from RAM to the next free block of NVMY. A reset before end of
Powerlatch prevents this saving and the last valid block is read out again at next initalisation.
If same block of Reset values is already read out for NC_MAX_RD_NVMY times, the flag
LV_ERR_RD_AR_NVMY is set.
Initialisation: (no Initialisation, because Activation during reset Phase)
Recurrence: once per Reset
Activation: at Reset
Formula section:
If block n is valid, but this block has been read already
NC_MAX_RD_AR_NVMY times
then LV_ERR_RD_AR_NVMY = 1
else LV_ERR_RD_AR_NVMY = 0

The CPU load is defined as the processor activity above the background level.
The variable CPU_LOAD_MAX represents the maximum detected CPU load value. The
calibration flag LC_CPU_LOAD_MAX_RST can be used in order to reset this variable.
The variable CPU_LOAD_MAX_TOT_DC represents the maximum CPU load value over
several driving cycles since ECU programming.
Initialisation: - at first ECU power up and non-volantile memory lost:
CPU_LOAD_MAX_TOT_DC = 0
- otherwise: restored from non-volantile memory
Formula section:
IF CPU_LOAD_MAX > CPU_LOAD_MAX_TOT_DC

THEN CPU_LOAD_MAX_TOT_DC = CPU_LOAD_MAX

Maximum system/Ercosek stack consumption (stored at shutdown)
The stack monitor of Ercosek operating system is called to gain information about the stack
consumption. The maximum values are stored at ECU shutdown to track the stack
consumption over several driving cycles.
The calculations are done, when no other task is pending (background task).
The following variables are provided by the Ercosek operating system:
E_OS_STATE_STACK:
- STACK_OK: Stack consumption of user and system stack in normal ranges (0..75 %)
- USTACK_OVFL, ESTACK_OVFL: Overflow of user or Ercosek stack (> 100 %). This is
extremely dangerous and therefore prompt actions to reach 75 % have to be taken.
- USTACK_NFULL, ESTACK_NFULL: User or Ercosek stack is nearly full (75..100 %).
Actions to fulfill the requirement of max. 75 % have to be taken.
E_OS_USED_USER_STACK: Used user stack size in byte.
E_OS_USED_SYS_STACK: Used system/Ercosek stack size in byte.
Initialisation: -
Recurrence: background
Activation: at every engine state
Deactivation: -

1.3 Basic System Definitions
1.3.1 Allocation of CRK / CAM angles
CRK disk:
The falling edge of the first tooth after the gap is 114 °CRK before the ignition TDC of the first
or the fourth cylinder.
CAM disk:
The electrical falling edge of the Intake CAM signal is positioned at tooth #114 (564°CRK
absolute), the electrical rising edge of the Intake CAM signal is located at tooth #54
(204°CRK abs.).
The distinction between tooth #1 and #61 is done depending on the Intake CAM signal level
during the gap:
- Intake CAM signal level = high during the gap, then tooth #61;
- Intake CAM signal level = low during the gap, then tooth #1.
The electrical falling edge of the Exhaust CAM signal is positioned at tooth #75 (336°CRK
abs.), the electrical rising edge of the Exhaust CAM signal is located at tooth #15 (696°CRK
abs.)
A "true power-on" logic of the CAM-Sensor is mandatory for this setup.
The firing order is stored as follows: 1 - 3 - 4 - 2 .
The injection valves are controlled according to the firing order.
An angle at start of injection of 0° means: The injection valve begins to open at the previous
ignition TDC of this cylinder. A negative SOI means that the injection will start between the
previous TDC of this cylinder and the next TDC of this cylinder.
1.3.2 Cylinder numbering

In the software the cylinders are numbered logically with 0...3, whereas in the ECU-hardware
they are numbered 1...4.
If in the specification a cylinder-specific-variable is mentioned with ...[CYL] then always the
logic value is ment.
The firing order of the engine follows continuously from logic 0 to logic 3, whereas the
physical firing order is 1 - 3 - 4 - 2.
The relation between logical and physical cylinder numbers is as follows:

SW-Logic HW-Logic Physical

0 1 1
1 2 3
2 3 4
3 4 2

TAM sensor (via CAN) out of range diagnosis (OBD1): via Project specific solutions
TIA and TAM sensor plausibility diagnoses (OBDII)
Physical background of the function:
The AIRT uses basically 2 Physical / Mathematical laws:
_ The heat transfer law for the mix of two gas:

Between fresh air and burned gases coming from EGR (we suppose that the isobaric heat
capacities are the same for air and EGR gases).
megr C p (Tegr − T ) = mair C p (T − Tair ) ⇒ T = Tegr × ratio _ egr + Tair × (1 − ratio _ egr )
To estimate the air temperature, we use the following law :
_ The Reynolds law:

It describes the heat transfers of a gas flowing into a tube. For gases at moderate
temperature, the change of temperature between the final gas temperature and the initial one
follows the law:
T − Tgas =
[
K (L, D ) Ttube − Tgas ]
flow 0.2
Where: K depends on the length of the tube (L) and its diameter (D).
flow is the mass flow of gas.

1.7 General information
Target
The goal of the EGPR is to calculate the actual valid exhaust pressure in the exhaust
manifold.
There is an increase of the pressure in the exhaust pipe in comparison to the ambient
pressure. The increase of the pressure is higher with increasing mass flow in the exhaust
pipe. The cylinder mass air flow is direct proportional to the exhaust mass flow. Therefore the
pressure increase in the exhaust pipe is a function of the engine mass flow.
Dependence of IMM on reliable measurement signals

To reach always λ = 1, i.e. in steady state/ transient, cold/warm engine operating, a precise
load signal is required. The IMM strongly depends on reliable measurement signals, for two
main reasons:
_ In systems equipped with an air-mass flow sensor (HFM) during steady state engine
operation, the measured air-mass flow signal (MAF) usually equals the air-mass flow into the
cylinder, which is the base for injection time calculation. This is not true during transient
engine operation, because of the filling characteristic of the manifold. The HFM is mounted in
front of the intake manifold which behaves during transient as a mass storage system. To
avoid λ deviations, the dynamic behaviour (in steady state and transient engine operating) of
the intake manifold is calculated via the “IMM”.
_ Systems equipped with a manifold pressure (MAP) sensor do not have problems with the
filling dynamics of the intake manifold. Due to the fact that the air-mass flow is not directly
measured but only calculated out of the air density, therefore it strongly depends on the
knowledge of the air-temperature in the cylinder. Any deviations from the temperatures valid
during the calibration of the engine have to be compensated.

1.9 ENSD General
1.9.1 General Description
Up to 4 camshaft sensors are supported.
The ENSD aggregate calculates all output data which depend on crankshaft and camshaft
sensor information. This includes:
- engine position
- engine speed
- engine speed gradient
- segment number and period
- synchronization status
- diagnosis and limp-home flags
- camshaft / VVT position feedback
- min./max. engine position for pre-injection
At engine start, three synchronization modes are activated:

1) Crankshaft (self-)synchronization:
The purpose of this synchronization mode is to identify the crankshaft position (0...360°
CRK). The crankshaft position is clearly identified at the reference gap of the crankshaft
target wheel.
2) Camshaft (self-)synchronization:
The purpose of this synchronization mode is to identify the camshaft position (0..720° CRK).
The camshaft position is clearly identified as soon as an unambigous camshaft edge pattern
is found.
3) Camshaft/crankshaft synchronization:
The purpose of this synchronization mode is to identify the engine position (0..720° CRK).
The engine position is clearly identified as soon as an unambigous crankshaft to camshaft
position is found.
Injection / Ignition can be enabled as soon as
- engine position is identified (MPI engines)

1.10.1 Target / Objectives of ERRM function
The purpose of the Error Management is :
- to collect, store and provide diagnostics information for repair and inspection programs
- to inform the driver via dashboard lamps from malfunctions which could affect emissions
compliance with regulations (CARB for US market / EOBD for European market).

Principle of the dynamic error management is to receive diagnoses results (filtered or not by
anti-bounce, muliti-condition, or statistical algorithms). These results are managed as
diagnoses failures, according CARB and EOBD standards.

Dynamic Error Management core

The dynamic error management core manages different failures states thanks to the fault
detection performed by the diagnoses : detected, present, temporary, pending, disappeared
and confirmed. All failures are detected without any limitation on quantity. On the contrary,
the number of present failures able to be stored into dynamic memory is limited.
Management of this limitation is performed thanks to priority rules mecanism.
When a failure is stored into dynamic memory, the related environment data is stored, the
lamp management may force lamp illumination (MIL, WAL,...), and DTCs management is
done until failure is deleted. When deleted, failures are stored into history memory.
History memory
History memory permits to trace historic of deleted failures. Some specific information are
stored for each deleted failure. Only the more pertinent data linked to failure shall be stored.
Debounce algorithm
The debounce algorithms is in charge of detected failures filtering according several
available and predefined filters.
Multi-conditions debounce algorithm

Debounce algorithm able to filter failures according a conditions per symptoms based
algorithm.
Cycle manager
Cycle manager computes driving cycle and warm-up cycle according to engine states and
engine coolant temperature. Cycle manager permits to evaluate failure states.
Failures class
Each failure can be configured to obtain a specific behaviour : emission relevant or not, can
illuminate MIL or not ... This module contain to all the predefined behaviours each failure can
be associated with. It permits to symplify greatly tuning of diagnosis by decreasing quantity of
calibrations.
DTC management
DTC management permits to catch some data when a failure becomes present and to
generate a code identifier, called DTC. It permits to identify default of the function.
Communication interface
This module allow to access failure memory data related to error management such as
freeze frame, stored DTCs, readiness codes.

Priority rules
This module manages dynamic memory size limitation. It defines criteria, called priority rules,
to store or not a new failure into this dynamic memory.

1.11 EXTC General

The aggregate EXTC –EXhaust system Temperature Control- concerns the component
overheating prevention and catalyst heating.
1.11.1 Components overheating prevention functions
There are 3 measures to reduce the temperature in the exhaust line. With high temperature
first ignition retardation shell be inhibited, because it causes high exhaust temperature due to
worse combustion efficiency (used for catalyst heating). The 2nd measure is the enrichment
of the air/fuel mixture, what makes the temperature decrease. The 3rd measure is the
reduction of the indicated torque. With high catalyst temperature especially after a time with
enriched mixture it is necessary to inhibit fuel cutoff in pull phase. This function is located in
Appl. Inc. and can be modified by project in "Overheating prevention (Appl. Inc.)". In the
figure below the overheating prevention interfaces are marked gray.
1.11.1.1 Minimum ignition limitation
The inhibition of late ignition angles is realized via limitation of the minimum ignition
difference to reference ignition - IGA_DIF_MIN_TEG. In general this value does not limit the
ignition itself, but reduces the torque reserve! For steady state environment this corresponds
to an ignition advance. Dynamic torque reduction via ignition retardation below
IGA_MIN_TEG is allowed!
For direct limitation of the ignition the value IGA_DIF_MIN_TEG_BAS has to limit
IGA_DIF_MIN. This function has to be done by the project in "(TQM) Minimum ignition
angle".
According specification: "IGA_MIN limitation for exhaust gas temperature protection"
1.11.1.2 Enrichment of air-fuel mixture

With richer mixture the exhaust temperature can be lowered. For catalyst overheating
prevention there is an I–controller. The number of temperatures which are to be controlled
and their location can be specified in Appl. Inc. and configuration. It is recommended to use
for controlling static catalyst temperatures to realize a better control response. For turbine
overheating prevention -if existent- there is a P-I--controller. The lambda-interface is
LAMB_OHP and concerns the minimum of LAMB_COP (for catalyst prevention) and
LAMB_TUR_OHP (for turbine prevention).
According specification: "Overheating prevention (Appl. Inc.)"; "Catalyst overheating prevention"; "Turbocharger
overheating prevention"
1.11.1.3 Torque reduction

The reduction of the indicated torque shell normally not become effective – depends on
catalyst design. The function can be activated if the Lambda-setpoint is on bottom limit and
the temperature is still high.

According specification: "Torque based overheating prevention"; "Torque based turbine overheating prevention"
1.11.2 Catalyst heating functions

With EXTC you can impact on several setpoints to optimize them for quick light off of the
catalyst and for minimum emissions. Catalyst heating can be activated for after start catalyst
heating and for catalyst heating in low load to avoid temperatures below the catalyst working
temperature.
The parameters for catalyst heating are:

• TQ_ADD_CH - torque reserve (results in air mass flow and ignition)

• LAMB_CH - air-fuel-mixture
• N_SP_IS_CH - idle speed setpoint
• FUP_RES_H_SP_CH - fuel pressure setpoint – only relevant HPDI engines
• CAM_SP_IVVT_CH_IN/EX - camshaft setpoints (for variable valve timing)

• EOI_2_MPLH_CH - end of 2nd injection during MPLH -only AGGR-Vers. 2
• FAC_MFF_SP_1_MPLH_CH - Split up factor for MPLH -only AGGR-Vers. 2
These setpoints are inputs for other aggregates and are used if catalyst heating is active.
Some of them are inputs in application incidences of other aggregates and can be used in
different ways. The catalyst heating interfaces are marked black.

1.12 EXTD General

EXTD (EXhaust system Temperature Determination) is the aggregate where all necessary
temperatures in the exhaust line are determined. These temperatures are used for different
purposes in different other functionalities:
1. Component overheating prevention: Turbine and Catalyst overheating prevention
2. Lambda sensor heater management
3. Catalyst efficiency diagnosis
Additionally EXTD is responsible for the dew point detection (or dew point passed detection)
which is used for the full activation of the lambda sensor heater.
In general there are two ways to determine the temperatures in the exhaust line:
1. Measurement of the exhaust gas temperature
2. Model of the exhaust temperature dependent on the engine operating conditions
The model is always necessary to have a back up information in case of sensor damage and
the sensor damage has also to be detected.
So EXTD can be split up in 4 parts:

1. Exhaust gas temperature sensor acquisition
2. Exhaust gas temperature sensor diagnosis
3. Exhaust gas temperature model
4. Dew point detection
1.12.1 Exhaust gas temperature sensor acquisition

Three specifications belong to this part:
1. EXTD infrastructure requirement specification (IRS): Specifies all information
concerning the hardware of the ECU and how often the sensor information is
updated. If no sensor is available in the system (NC_TEG_SENS_TYP = No Sensor)
this specification is skipped.
2. Exhaust gas temperature sensors (Appl. Inc.): Project specific part to inhibit the
sensor acquisition for different cases e.g.: If the sensor is only available for certain
configurations: Turbo / non Turbo; US market / European market. If no sensor is
available in the system (NC_TEG_SENS_TYP = No Sensor) this specification is
skipped.
3. Exhaust gas temperature sensors: Deals with the sensor information acquisition
which can be the raw value of the ADC converter or a PWM value in case of a sensor
type with external evaluation control unit which communicated with the ECU by PWM
information. Conversion of the raw value in a "raw" exhaust gas temperature and
filtering of this "raw" exhaust gas temperature. If no sensor is available in the system
(NC_TEG_SENS_TYP = No Sensor) TEG_MES is initialized by zero within this
specification.
1.12.2 Exhaust gas temperature sensor diagnosis

This part consists out of two specifications:
1. Exhaust gas temperature sensor diagnosis (Appl. Inc.): Project specific part
where the conditions for the activation of the different diagnosis are specified and
also the anti bounce behaviour of the different diagnosis are specified. If no sensor is
available in the system (NC_TEG_SENS_TYP = No Sensor) this specification is
skipped.

Document Key Pages

E150-024.49.01 SPE 000 20.0 158 of 5555
2. Exhaust gas temperature sensor diagnosis: 4 different types of diagnosis are

carried out here: electrical diagnosis, cold start diagnosis, increment diagnosis and
gradient diagnosis. If no sensor is available in the system (NC_TEG_SENS_TYP =
No Sensor) the global error flag LV_ERR_TEG_MES is initialized by zero.
1.12.3 Exhaust gas temperature model

This part is the most important and also the biggest part of EXTD with the following 7
specifications:
1. Exhaust gas temperature model (Appl. Inc.): In this project specific part almost all
inputs of the exhaust gas temperature model are generated out of the available
system information. E.g.: The engine speed for the exhaust gas temperature model
N_TEG is generated out of the system variable N. This is done to deal with different
customer request (e.g.: to have a filtered engine speed as input for the exhaust gas
temperature model). Additionally several customer specific corrections (e.g.:
TEG_ENG_OUT_ADD_CUS) for different purposes (e.g.: VVL and MPLH
corrections) can be generated here.
2. Exhaust gas temperature model: This module is the manager of the exhaust gas
temperature model. All component models (Engine out- / Tube- / Turbine- and
Catalyst exhaust gas temperature model) are coordinated here. This means the
manager calls the different component models in the right order with the correct
update rate and writes the result calculated in the component model in the right
position of the arrays (TEG_DYN_MDL, TEG, LV_TEMP_DEW_MDL...). It handles
also at which position the sensor information is used instead of the model based
value. There is only one calibration data in the specification
LC_TEG_MDL_SENS_ENA which has to be set to one if the sensor information shall
be used (if no sensor error detected). So for calibration this specification is not
important.
3. Engine out exhaust gas temperature model: In this module all engine operating
point dependencies (e.g.: engine speed, load, ignition angle ...) are used to determine
the first temperature which is effective engine out exhaust gas temperature.
Additional the engine out exhaust gas humidity is determined here.
4. Tube exhaust gas temperature model: This model part is used to simulate the
cooling down of the exhaust gas and the influence on the dynamic of the exhaust gas
temperature by the influence of the heat capacity of an exhaust pipe like the exhaust
manifold and by the external conditions like ambient temperature and vehicle speed.
5. Turbine exhaust gas temperature model: This model part is used to simulate the
cooling down of the exhaust gas due to the turbine power and the influence on the
dynamic of the exhaust gas temperature by the influence of the heat capacity of the
turbine housing and by the external conditions like ambient temperature and vehicle
speed.
6. Catalyst exhaust gas temperature model: This model part is used to simulate the
catalyst temperature and it's dynamic. Therefore the exothermic reactions are
considered to calculate the increased temperature in the catalyst and also ambient
temperature and vehicle speed are again used to calculate the exhaust gas
temperature downstream catalyst.
7. EXTD Output selection: At the end of the calculation all exhaust gas temperatures
are available in the array TEG[NC_NR_TEG_MDL] but the output of the aggregate
are values with a certain naming (e.g.: TEG_DYN_UP_CAT). For each value with a
certain naming a value out of TEG has to be selected. This mapping is done in this
module.

1.12.4 Dew point detection

The dew point detection is a project specific specification because there are several
strategies for this functionality. All information's out of the exhaust gas temperature model,
like modelled tube wall temperatures and the internal dew point flags for each position in the
exhaust line LV_TEMP_DEW_MDL[NC_NR_TEG_MDL], can be used to determine the "dew
point passed flag" LV_TEMP_DEW_LS_UP/DOWN for the upstream and downstream
sensor. But also mass air flow integral can be used to set the dew point flag. Of course also
combinations out of these information's are possible.

1.12.5 Introduction
This document is the Aggregate Integration Document of the IGRE Aggregate. Its aim is to
describe the integration constraints of this aggregate with the others. It aims with interfaces
(imported and exported), architecture, and configuration. This document covers all versions
of the IGRE aggregate.
1.12.6 Purpose
The IGRE Aggregate defines the calculation of the dwell time, the ignition realization and the
ignition diagnosis functions.
Basically the ignition command function has to fulfill two main tasks; to ensure that there is
enough energy in the ignition coil and to start the combustion at the requested ignition angle.
Knowing the desired ignition advance, engine speed and several other parameters, this
aggregate determines the correct timing for switching ON and OFF the power stage in order
to bring the ignition coil to the necessary primary current value. The time during ON state
(load phase) of the switch is often improperly called Dwell time (with reference to the dwell
ratio in breaker systems).
At the end of this Dwell time the ignition stage is switched OFF and the ignition spark is
created. The OFF event corresponds to the advance ignition angle (IGA_IGC).

Voltage

The ignition command functions and the linked diagnostic functions are regrouped in the
ignition realisation aggregate.
1.12.7 Function Description
This function sets the angular position of the dwell time turn on in order to have the time to
set up the necessary current in the ignition coil.
The strategy is based on a priority of the ignition angle. If dwell time priority is requested the
minimum dwell time is equal to maximum dwell time.

The strategy respects ignition coils with dual and single outputs. This function could be used
independently of the number of cylinders (x) and the geometry of the crankshaft target wheel.
All of the functions described in this section operate over the entire engine speed range.
• Realization of minimum 1 ignition spark per cycle
• Realization of a number of multiple spark

1.13 IGSP General

The IGSP Aggregate defines the calculation of the ignition angles to be applied on an engine
with a TQ based EMS.
The Ignition functionality of an engine management system can be organised in two different
parts. A first part is the determination of the ignition angle itself, and a second one is the
realisation of this ignition angle with the management of the charge and the discharge of
coils. This document is the “over head” for the first part, “Ignition Angle Calculation / Ignition
Angle Setpoint”. The information of this function will thus been send to the coil for the proper
application on the spark of the mandatory determined ignition angle.
The goal of this aggregate is to calculate the 3 ignition angles (BAS, REF and MIN) that
describe the limits of engine behaviour and capacities and then to co-ordinate this basic
structural angle with the ignition angle request from the Torque manager to produce the
requested torque in the requested period, with the limitation to the engine possibilities. The
ignition angle hence calculated will be provided to the second part in order to be realised as
best by the ignition coil.
The Ignition structure gets an ignition angle request from torque structure (named
IGA_DIF_TQ_REQ) which is the transformation in term of ignition angle of the setpoint for
TQ. It provides representative ignition angles to the other functionality. With this information,
the torque structure can interpret and define which ignition angle has to be realised. Then the
ignition angle choice between TQ requests and engine possibilities with IGA is done to
produce the best fitted (in term of TQ production and engine limits respect) ignition angle that
will be applied to each cylinder.

♦ External limitation on minimum ignition angle

Some external limitations can be admitted on the minimum ignition in some particular engine
running area.
Each projects have to provide their specific considerations for this function.

all corrections on the ignition angles.
• Basic ignition angle at start

This module enables a specific management of IGA during start phase.
• Ignition angle general

This block manages all the ignition requests – regarding torque request and engine
capacities – and defines the IGA to be applied at the coil.
In case of switch to stratified mode only the module hereafter is calculated in the software.
• IGA Request for stratified mode

This module co-ordinates the calculation of the ignition angle IGA_AV_S[x] which is applied
to each different cylinder of the engine in Stratified combustion mode. This value is directly
related and fitted for one particular cylinder (cylinder x).

1.14 General information

1.14.1 Target
The purpose of the “Intake System” (INSY) is to coordinate the air flow controlling
components and to predict the air mass flow behavior. Needed is the prediction, as the
injection time is calculated based on the real mass-flow, which is present in the cylinder for
the considered combustion cycle. However, the injection time is calculated before the closure
of the intake valves, and parameters like MAP or MAF are still not known.
All this modeling aims to evaluate, at the moment of the injection time calculation, the
conditions in pressure and flow which are present at the closure of the intake valves for the
concerned combustion cycle. Therefore, the predicted pressure is calculated. This predicted
pressure is the estimation of the pressure value at the moment of the injection.
⇒ Calculation of MAF_THR, MAF_CYL and MAP in order to calculate MAP_PRED and
MAF.

1.14.3 Dependence of IMM on reliable measurement signals

To reach always λ = 1, i.e. in steady state / transient, cold / warm engine operating a precise
load signal is required. The IMM strongly depends on reliable measurement signals, for two
main reasons:
In systems equipped with an air-mass flow sensor (HFM) during steady state engine
operation, the measured air-mass flow signal (MAF_KGH) usually equals the air-mass flow
into the cylinder, which is the base for injection time calculation. This is not true during
transient engine operation, because of the filling characteristic of the manifold. The air-mass
flow sensor is mounted in front of the intake manifold, which behaves during transient as a
mass storage system. To avoid λ deviations, the dynamic behavior (in steady state and
transient engine operating) of the intake manifold is calculated via the “INSY”.
Systems equipped with a manifold pressure (MAP) sensor do not have problems with the
filling dynamics of the intake manifold. Because the air-mass flow is not directly measured
but only calculated out of the air density, it strongly depends on the knowledge of the air-
temperature in the manifold. Any deviations from the temperatures valid during the
calibration of the engine have to be compensated.

1.15.2 Physical/ mathematical laws used in the intake manifold model
• The IMM is based on the conservation of mass over the intake manifold. Assuming that
the air is an ideal gas this gives the basic equation:
∂ ⎛ pim Vim ⎞
⎜ ⎟ = m& in - m& out (3)
∂ t ⎜⎝ Rair Tim ⎟⎠
The inflowing air-mass flow is the sum of the throttle air-mass flow, the exhaust gas
recirculation, the flow through the canister purge solenoid (CPS) and the crank case air
flow (CRCV) m & in = m
& thr + m
& egr + m
& cps + m
& crcv . The outflow is the air-mass flow into the
cylinder.
Under the assumption that Tim and Vim are not time dependent (or at least quasi
stationary) the overall pressure change can be modeled as:
∂ R T
p im = air im (m
& THR + m

The complete calculation algorithm for the Intake manifold system is subdivided into six
major separate modules:
• application incidence for project specific adaptation
• calculation of the air/EGR partial pressures and air mass flows
• INSY-controller with reduced area controller and pressure up throttle controller
• ambient pressure adaptation with ambient pressure learning
• reduced area adaptation
• calculation of the pressure decrease in the air filter
• volumetric efficiency calculation
• basic reduced area calculation
In addition, there are modules that strictly do not belong to the IMM, but usually are handled
with the IMM:
• data acquisition for MAF values
• data acquisition for MAP values
The tuning of the complete IMM is therefore consequently also subdivided into the tuning of
the separate depicted modules.

1.16 Measurement Set-up

1.16.1 Required sensor equipment
The following sensors are required for a calibration of the IMM:
• Pressure sensor in the intake manifold
• Linear lambda sensor
• Air-mass flow sensor and / or a fuel-consumption measuring device
• Barometer in the test-cell
• Coolant temperature sensor
• Intake air temperature sensor
• Pressure sensor between air filter and throttle
• Pressure sensor in the exhaust system (if EGR is configured)
• Pressure sensor just in front of the EGR-valve (if EGR is configured)
• Temperature sensor in front of the EGR-valve (if EGR is configured)
1.16.2 Recommendations on sensor equipment

It is recommended to use calibrated sensors. At least the HFM and all pressure sensors
shall be calibrated. The HFM sensor should be calibrated completely mounted on the air-filter
module on the flow-bench (required time: about ½ day). The resulting table should be used
instead of the table in the ECU.
If possible, a pulsation compensated HFM sensor should be used. If the data acquisition is
capable of measuring external analogue channels, it is not necessary to use the system HFM
(i.e. the airflow sensor can be of any type). If no pulsation compensated HFM is used, it is
important to mount the sensor at a location where no pulsation effects occur. E.g. an oil
barrel, mounted upstream of the air-cleaner can be used as a low pass filter (do not mount it
downstream of the throttle, the barrel will be damaged). If the airflow sensor is mounted
upstream of the barrel, this ensures that no pulsation effects will occur. It is recommended to
mount an air-intake in front of the sensor.
1.16.3 Data acquisition system

If the data is acquired with a calibration system, it should be capable of measuring external
analogue channels. In addition, it should be possible to convert those measured voltages
into physical units by interpolation with tables (not only linear functions).
It should be possible to export measured data into tables either in ASCII or Excel file format.
1.16.4 Test bench

Duration of tests on engine dyno: 2 days

Duration of tests on chassis dyno: 1 week

Duration of tests on climatic chamber: 1-2 weeks
Duration of tests on altitude bench: 1 week
For the calibration of the intake manifold model at normal engine operation temperature,
there are no special requirements for the test bench.

If the IMM has to be calibrated during warm-up (temperature dependency) at the engine
dyno it would be helpful if the coolant (and the intake air) can be adjusted to any desired
temperature (e.g. use heat exchanger in coolant circuit).
If the dyno is equipped with an ACS (Automatic Calibration System), all steady state
measurements can be done very fast (and unattended) using the ACS.

1.17 Calibration Method

1.17.1 Calibration preparation
The following points have to be done or checked before beginning with the calibration:
• Pulsation compensated air-mass flow sensor is used
• HFM is mounted at a position where no pulsation takes place
• Calibration of the air-mass flow sensor was done with complete air-cleaner module and
resulting conversion table is used for conversion of voltage to air-mass flow
• Adaptation of the throttle position sensor stabilized
• Intake manifold has no leakage (especially required for MAF system)
• Throttle — and if used Idle speed actuator — should be nominal for principal calibration
• Run-in phase of the engine is finished
• All sensors (especially HFM and MAP) are calibrated and signals have been checked.
For a calibration of the temperature correction of the volumetric efficiency in addition the data
acquisition system has to be prepared so that it can be started directly before starting the
engine. Otherwise, data at low temperatures will be lost.
1.17.2 Points to be checked during the engine run

The following points have to be checked during the engine run:
• Engine is operating at nominal temperature (about 90°C)
• System intake air has desired value (usually about 25 °C)
1.17.3 Interfering functions

None
1.17.4 Test sequence

The steady state and transient calibrations are done on the engine test bench. The
temperature corrections of the volumetric efficiency have to be done on a climatic chamber.
Afterwards the steady state and transient calibrations have to be checked on a chassis dyno.
Altitude corrections and pressure adaptation have to be calibrated either on an altitude test
bench and/or on an altitude trip.

1.19 VVTI General
Objectives
The goal of the VVTI is to phase the opening period of the inlet and/or exhaust valves with
regard to the crankschaft. In other words, it is possible to change the closing point of the inlet
valves and/or the closing point of the exhaust valves.
This system provides the adjustment of a camshaft to a desired phasing ~ to a desired valve
timing. The desired camshaft position is further called setpoint. The setpoint can be any
position in the available adjustment range. Every project has to implement its determination
of the setpoint as a function of the engine operating state. The setpoint can be adapted to
the control algorithm slightly and the controller sets the camshaft to this setpoint.
Principle
The camshaft phasing is realised by means of an actuator that works with the engine oil. The
actuator has two chambers that can be filled and emptied by the oil. Filling one chamber and
emptying the second one leads to a change of the camshaft phasing. If the oil flow into and
out of the chambers is stopped the actuator holds its position, i.e. the camshaft does not
move (no additional movement to the basic rotary movement). The oil flow is controlled by
means of a solenoid proportional oil control valve. The solenoid is energised with a duty
cycle signal from 0 to 100 %. The piston of the valve is pressed against the solenoid by a
string. If 0 % energisation is applied the valve piston is in the passive stop position. The oil
flow causes that the actuator moves towards and remains in the actuator passive stop
position. If 100 % energisation is applied the actuator moves towards and remains in the
actuator active stop position. If an energisation is applied, in which the valve piston closes
both chambers or opens both in the same level, the actuator holds its position. Such
energisation is called holding energisation. It is approximately from 30 to 60 % duty cycle
depending especially on the voltage and solenoid temperature.
The IVVT system is an optional part of the engine. Its implementation has many benefit
impacts on the engine performance. The system allows to phase the opening period of the
valves continuously in the adjustment range of the actuator. Influences of IVVT on the engine
processes and how IVVT can improve the engine performance is briefly described in
following paragraphs.
There are two physical effects regarding the gas flow in the engine manifold. The first one is
the inertia of the gas flowing in a pipe (ram effect) and the second one is the wave effect.
The gas in the inlet pipe is accelerated during the induction stroke. The pressure in the
combustion chamber rises at the end of the induction phase because the piston already
moves towards the top dead centre. The kinetic energy of the flowing gas acts against the
combustion chamber pressure and helps to improve the volumetric efficiency. The ram effect
is very strong at high engine speeds. The inlet valve timing is to phase towards retard. The
inlet valve timing is to phase towards advanced at low engine speeds in order to minimise
the backflow due to the increased combustion chamber pressure.

The piston moving towards the bottom dead centre during the induction stroke creates a low
pressure wave (compared with the mean inlet pressure) running away from the combustion
chamber. It propagates with the velocity of sound in the pipe. This wave is reflected at the
open end of the pipe (manifold collector) as a high pressure wave running towards the
combustion chamber. If this high pressure wave reaches the inlet valve short before its
closing, improvement of the volumetric efficiency can be obtained. The time of the wave
arrival depends on the pipe length and time available, i.e., engine speed. The velocity of
sound changes slightly with the air temperature.

Document Key Pages

E150-024.49.01 SPE 000 20.0 185 of 5555
These two effects are superposed. It is possible to increase the maximum torque at low
speed and to keep the power output without increasing engine displacement by means of the
infinitely variable inlet valve timing.
There are similar effects on the exhaust side. The gas flowing in a pipe tends to create
vacuum if there is not enough gas supply from the combustion chamber, also "an anti-ram
effect". High pressure waves are produced during the exhaust period. They are reflected as
low pressure waves. It is possible to reduce the amount of the residual gases, and thus to
manage more space for the fresh air. The phasing of the exhaust valve timing can contribute
to improvement of the volumetric efficiency too. The high gas temperatures and high
pressures, especially amplitudes, in the exhaust system make these effects very sensitive to
changes of the engine load and speed.
The situation at full load has been described above. The IVVT system can improve the
engine performance at part load too. The means is the internal exhaust gas recirculation.
That is an intentional extension of the amount of the residual gases in the combustion
chamber. Higher portion of the residual gases improves the thermodynamic efficiency of the
cycle because of changed properties of the working fluids. Further, it is necessary to
increase the inlet pressure in order to have the same power output (~ the same volumetric
efficiency) at higher portion of the residual gases. This decreases the pumping losses in part
load. It leads to the reduction of the fuel consumption. Higher portion of the residual gases
dilutes the air-fuel mixture. The maximum combustion temperature is lowered and this
reduces the production of oxides of nitrogen.
Higher portions of the residual gases are obtained by moving inlet towards advanced and
exhaust towards retard. The exhaust gases flows into the inlet port at the opening of the inlet
valve because the combustion chamber pressure is higher than the inlet system one. This
leads to a decrease of the combustion chamber pressure, and thus, there can be a backflow
of the exhaust gases from the exhaust port. The exhaust gases in the inlet port are then
inducted into the combustion chamber during the main induction period.
The extension of the amount of the residual gases is limited. The ignition properties of the
mixture get worse. It leads to higher engine roughness. The driver must not feel it especially
in idle. The combustion duration becomes longer which acts against the fuel efficiency
improvement. It is obvious that the ignition angle has to be fitted. On the other hand the IVVT
system allows to decrease the engine roughness in idle in comparison with an engine with
fixed timing. The fixed timing is a compromise for the maximum power output, maximum
torque and idle stability. The variable timing can have the minimum valve overlap smaller,
and thus less residual gases in idle and therefore better idle stability.
There are further effects of the IVVT system on the engine performance. It is possible to
reduce the fuel film creation on the inlet port walls by means of the backflow of the hot gases
from the combustion chamber. It can reduce the production of unburned hydrocarbons during
the warm-up phase. The catalyst light-off steps and the catalyst overheating protection can
be supported by IVVT. The variable valve timing influences the flow field within the
combustion chamber which is a part of the combustion process in the gasoline direct
injection engines.
Description
The IVVT system can be in active or inactive state. The inactive one is characterised by
permanent low level energisation (~0-15 % PWM) of the solenoid valve. The active state
means that the camshaft position is controlled to a desired setpoint. It is the normal
prevailing state. The system is inactive when the engine is stopped. The following steps are
done before reaching the active state: check min/max oil temperature and min/max battery
voltage (continuously done), wait for enough oil pressure after the engine start, wait for the
end of the reference position adaptation, active state is reached. If there is a failure the IVVT

system is inactivated. In some cases the system remains partly active (some camshafts are
active, some are inactive) in order to enable bank balancing (see bellow).
The reference position adaptation is done by the ENSD aggregate when enabled by the
IVVT function. The aim of the adaptation is to eliminate inaccuracies of the camshaft position
acquisition. The primary camshaft position from ENSD in its coordinate system is
recalculated into an IVVT camshaft position. This position is related to the gas-exchange top
dead centre.
The setpoint is calculated dependent on the engine operating state (combustion mode, load,
speed, coolant temperature, etc.). The inlet setpoint can be prioritised to the exhaust one at
low oil pressure. It means that the exhaust setpoint is kept untill inlet reaches its desired
position and then the map exhaust setpoint is handed over.
The setpoint is worked up in order to facilitate the position control. The main operations are:
limitation to the possible adjustment range and setpoint close to the reference position
equals the reference position. If the setpoint is in the reference position for a longer time the
reference position adaptation is enabled.
The camshaft position control is based on a superposition of the holding energisation and
time limited low or high level energisations. Generally, the holding energisation is applied.
The controller calculates an energisation duration and its level dependent on the setpoint
course and the camshaft deviation from the setpoint. The holding energisation is replaced by
the calculated level for the calculated time. This is realised at camshaft edges where the
camshaft position is acquired.
The controller consists of a Pre-control and P-control. The Pre-control manages part of the
setpoint change and reacts to setpoint changes quickly. The delay and the adjustment speed
dependent on the engine speed and oil temperature are the Pre-control parameters. The
P-control manages the residual part of the setpoint change and disturbances.
The primary holding duty cycle is a feed-forward control (map dependent on the battery
voltage and modelled solenoid temperature). A correction is usually needed for every
individual engine due to tolerances. This is realised by means of two adaptations (one of
them is a kind of I-control) which evaluate the camshaft deviation and drift at steady setpoint
conditions.
There is a balancing of the camshaft positions in the individual banks of a 2-bank system.
Unequal adjustment speeds or a failure in one bank can cause different positions in the
individual banks. An interbank controller calculates individual setpoints so that the
differences between the banks are minimal.
There are some diagnoses in the IVVT system. The electrical failures "short circuit to plus",
"short circuit to ground" and "open circuit" can be detected. A chain/belt jump is monitored.
There is a diagnosis for the detection of a persistent camshaft deviation and/or slow
responsing actuator. The system can be tested by means of a short trip test (special setpoint
course) at EOL test or as a garage test.

The IVVT system influences the gas-exchange process, especially the amount of the
residual gases. The ignition angle has to be corrected. Ignition angle corrections (one for the
basic and one for the reference ignition angle) are outputs from the VVTI aggregate.
There is an important question how the engine reacts on an IVVT failure. It is possible to test
it by means of a special algorithm. The operating point dependent setpoint is used in the
diagnoses. The controller works with a special setpoint, e.g. a constant for a blocked
actuator. The engine behavior, especially the emission production, can be observed.
A multi-segment camshaft target wheel can be used. It is not necessary to use all edges for

on the controll if the time between edges is shorter than the system delay. Additionally, there

is a huge runtime demand if many edges are used. It is possible to strech the setpoint
calcualtion to every n-th engine revolution (dependent on the engine speed) for runtime
saving.
Flowchart
For the sake of clearness the basic flowchart (architecture) of the VVTI aggregate presented
here is simplified. Only the main signals are shown. Further, names of some quantities were
shortened. Following substitions were done: "x" = "IVVT_IN(_EX)" and "z" = "IN(_EX)".

Aggregate functions
This aggregate version consists of the following functions:
• VVT State - Valve timing data are defined here. Camshaft position is calculated. IVVT
system state is determined.
• VVT SP (setpoint) - Calculation of camshaft position setpoint as a function of engine
state.
• VVT Control - Camshaft position control including feed-forward control, feed-back control
and adaptations.
• VVT Interface BSW - Realisation of control signals. Ouput signal diagnosis information is
acquired.
• VVT LIH (limp home) manager - Manages IVVT system state in case of a failure.
• VVT OBDI - Output signal diagnosis.
• VVT OBDII - Crankshaft to camshaft mechanics violation diagnosis (chain/belt jump).
Camshaft position deviation diagnosis (actuator jammed, actuator slow responsing). Rate
based monitoring interface.
• VVT EOL test - IVVT short trip (prescribed setpoint course is evaluated).
• VVT Ignition corr (correction) - Ignition angle correction as a function of a camshaft
position not in reference position.

1.34 ENTE Configuration data
Input data:
NLC_TCO_2_CONF
The logical constants NC(NLC)_xxx_CONF are necessary to adapt the Aggregate to a given
system environment. The values describe either the variant of a used system component, or
a vehicle component is available or not.
With use of the logical constant NLC_ECT_CONF the availability of an electronically
controlled thermostat within the system is determined. In case of a vehicle configuration with
an ECT, the component control and diagnosis is included within the aggregate version.
(refer: ENTE A.I.D.)
With use of the logical constant NLC_TCO_2_CONF the availability of a coolant temperature
sensor at radiator outlet is determined. In case of a vehicle configuration with a TCO_2
sensor, the sensor signal acquisition and diagnosis is included within the aggregate version.
(refer: ENTE A.I.D.)
The configuration constant NC_ECF_CONF allows to determine the wanted fan control
strategy. In principal it is possible to choose between a RLY- or a PWM-control architecture.
A RLY/PWM fan control strategy in parallel is also existing. In this case the aggregate
architecture allows switching either the control of RLY-fan(s) or the control of PWM–fan(s)
during ECU runtime depending on the setting of a corresponding configuration bit. The
control of both variants (RLY- and PWM-fan(s)) at the same time is not allowed and not
supported within the aggregate.
Independent on the chosen fan control strategy (PWM/RLY), the configuration constant
NC_ECF_NR describes the number of available cooling fans (hardware components) at the
vehicle. In case of a PWM-fan configuration, the number of available PWM cooling fans at
the vehicle is always equal to the number of PWM fan output stages provided by the ECU
hardware.
Because one or more RLY-switch(es) may control only one cooling fan (hardware
component) in case of a RLY-fan configuration, the number of RLY-switch(es) per cooling
fan can be different. With use of the configuration constant NC_ECF_RLY_NR, the number
of RLY output stages per cooling fan are determined.
With the configuration constant NC_NR_TCO_SENS the number of available coolant

temperature sensors is determined, which provide the sensor voltage values to calculate
TCO, TCO_2, TCO_n.

The following describes the general rules for determination of the configuration data.

Notes:
• The configuration switch NC_STATE_VLS_UP_SIG_ACQ denotes whether signal filtering
shall be applied to the linear lambda sensor’s raw signal provided by the BSW prior to
further signal processing. If signal filtering shall be applied NC_STATE_VLS_UP_SIG_ACQ
shall be set to 1. If not or if binary upstream sensor is used
NC_STATE_VLS_UP_SIG_ACQ shall be set to 0.
• The PWM frequency for the oxygen sensor heater must be adjusted to values larger
than 5Hz, i.e. NC_FRQ_LSHPWM_UP >= 5Hz and NC_FRQ_LSHPWM_DOWN >=
5Hz. Usually no values larger than 100 Hz are applied, the exact value has to be derived
from the corresponding sensor specification.

In order to minimize the necessary amount of different ECU variants by different equipment
in the vehicles under mass production conditions, it is necessary to build a structure into the
ECU software that allows to select different control algorithm and access to different
calibration data maps and constants by setting of configuration bytes.

It is possible to change the variants during the development process by SAM 2000 whereas
the versions could be selected by KW 2000 (SAM-Dias or service tester) at the end of line-
programming or at the service. The underlined variant respectively version is the default one.
Remark: A change of a version or variant will only be valid after system reset (that
means when the power latch phase has expired).
This applies also to the outputs CONF_xxx and CONF_xxx_CAN.
Exception: CONF_CRU is learnt after Key-On without Powerlatch,
it is effective immediately.

1.40.2.1 Gearbox Type

The presence of an automatic gearbox is learnt depending if there is a signal from the
TCU_TYPE from TCU on the CAN-bus. With C_CONF_TCU_LEARN = 0 also a learnt TCU
can be reset from CONF_TCU = 00H or 0AH to CONF_TCU = 0FH.
The learning strategy includes the following items:
- A virgin ECU is configured to MT.
- If the configuration of the ECU is MT then the ECU monitors the CAN concerning the
related messages during 10s after key on.
- At a learnt ECU the normal CAN-timeout-diagnosis is active.
- It is possible to set back an already learnt TCU by diagnosis tool.
Remark:
It is necessary to have a different calibration of some maps depending on AT- or MT-
gearbox-type. Due to the setting of the gearbox-type some maps are existing double. The
maps for the AT are signed with ‘_AT’ at the end of the map. If CONF_TCU = 0Fh (MT) then
the map without ‘_AT’ is choosen and vice versa. In the specification a double existing map
is listed once but marked with (_AT) at the end of the map.
At the moment separated maps for CVT are not available.

1.40.2.3 Acquisition of the ambient air temperature
For turbo charged engines there are two possibilities to recieve TAM in formation: From the
CAN-bus or from an analog sensor value.
The learning strategy for turbo charged engines (LC_TCHA_CONF = 1) includes the
following items:
- A virgin ECU is configured to CONF_TAM = 0 (no sensor value available).
- The ECU monitors the CAN concerning the related messages during a certain time
(C_T_TAM_LEARN) after reset. If the respective CAN messages were received
CONF_TAM is set to 1 (TAM via CAN available).
- If the respective CAN messages were not received it is assumed that an analog signal is
available and CONF_TAM is set to 2.
- It is possible to set back an already learnt TAM signal by diagnosis tool.
For non charged engines (LC_TCHA_CONF = 0) CONF_TAM is always set to 0.
CONF_TAM = 0: no TAM sensor available or not yet learnt

CONF_TAM = 1: TAM via CAN (only for LC_TCHA_CONF = 1)

1.40.2.4 Air Condition Control
The presence of an air condition control is learnt depending if there is once the signal for "air
condition control selected" recognized. In order to prevent signal disturbance being
interpreted as ACIN, the LV_IM_ACIN has to be present during 3 following recurrences.
Initialisation: at reset:
CONF_ACC: restored from NVMY; 0 in case of 1st power up or NVMY lost
CTR_ACC_LEARN = 0
Recurrence: 1000 ms
If CONF_ACC = 0 (no air condition control present)

1.40.2.5 Vehicle Speed Input

For non-OBD II-variants the vehicle speed input is coming only from the gearbox. In this case
CONF_VS = 0, as the variant-coding is C_CONF_VS = 0 (see chapter “Variant coding”).
For OBD II-variants (C_CONF_VS = 1) it is possible to obtain the input for the vehicle speed
from an inductive wheel speed sensor or from ABS. The ECU is able to distinguish the two
inputs by comparing the two different signals and to learn the actual configuration.
Learning strategy:
The learning is performed only once for virgin ECU and C_CONF_VS = 1 and CONF_VS ≠ 1
or 2 hex. During learning CONF_VS is 3, that means the learning is active and the result of
the learning is not known yet.
One of the configurations (ABS or inductive wheel speed sensor) is considered as learned, if
during C_T_VS_MIN_LEARN seconds VS_ABS or VS_WHEEL_INDU is greater than
C_VS_MIN_LEARN and the VS-change is smaller than C_VS_DIF_MAX_LEARN. If the
conditions are fullfilled for both inputs at the same time the ABS-variant is learned (as the
signal coming from ABS is considered more stable):

If LV_CDN_VB_MIN_DIAG = 1
then a timer is started for C_T_VS_MIN_LEARN seconds
If (VS_WHEEL_INDU > C_VS_MIN_LEARN
and ⏐VS_WHEEL_INDUn-VS_WHEEL_INDUn-1⏐< C_VS_DIF_MAX_LEARN)
then CONF_VS = 2 (Vehicle speed signal acquisition from inductive sensor)
If (VS_ABS > C_VS_MIN_LEARN

and ⏐VS_ABSn - VS_ABSn-1⏐ < C_VS_DIF_MAX_LEARN)
then CONF_VS = 1 (Vehicle speed signal acquisition from ABS)
Vehicle speed during learning:

During learning (CONF_VS = 3) the vehicle speed is determined as follows :
a). if VS_ABS = 0 and VS_WHEEL_INDU = 0 then VS = 0

b). if VS_ABS > 0 and VS_WHEEL_INDU = 0 then VS = VS_ABS
c). if VS_ABS = 0 and VS_WHEEL_INDU > 0 then VS = VS_WHEEL_INDU
d). if VS_ABS > 0 and VS_WHEEL_INDU > 0 then VS = VS_ABS
(as the signal coming from ABS-input is considered more stable)
Remark:
The learned configuration is stored in non-volatile memory.
It is possible to change the variant by SAM 2000 and therefore a new learning is performed
after next engine start. This happens also after an erasement of the learned configuration via
KW 2000 (SAM-S or service tester) at the end of line-programming or at the service.
1.40.2.6 Acquisition of the aircon control unit configuration

The presence of a external control unit is learnt depending if there is a signal from the FATC
on the CAN-bus.
- A virgin ECU is configured to CONF_ACC_FATC = 0
- The ECU monitors the CAN concerning the related messages during a certain time
(C_T_ACC_FATC_LEARN) after reset. If the respective CAN messages were received
CONF_ACC_FATC is set to 1 (ACC message via CAN available).

- If the respective CAN messages were not received it is assumed that no presence of
FATC
- It is possible to set back an already learnt FATC configuration by diagnosis tool.
Initialization: - at first power up or non-volatile memory lost:

CONF_ACC_FATC = 0
- otherwise: restored from non-volatile memory
- at reset: T_ACC_FATC_LEARN = C_T_ACC_FATC_LEARN

1.45 INTC - Introduction
Intersystem communication stands for the communication across different control units
(ECU) for various applications. The exchange of application data takes place in the form of
messages. Data links like CAN, LIN or FlexRay are used for this communication purpose.
This document provides the brief introduction of these datalink layer protocols.
Signal flow diagram:
ECU1 ECU2 ECUn
CAN / LIN / Flex ray
Description:
LIN
LIN stands for Local Interconnect Network.
LIN is a single wire bus system.
LIN network is a single master system with a maximum of 15 slave nodes.
LIN was designed to link switches, actuators and sensors in to a sub-bus that connects to
the main bus, usually via a CAN.
LIN implementation is based on common UART/SCI interface hardware.
LIN is an inexpensive, low speed (from 1 to 20KiloBitsPerSecond), serial multiplexing
protocol.
Most of the times the LIN master node implementation is done in the ECU. The LIN master
node implementation in an ECU involves three different layers

- Application software
- LIN data link layer
- Low level Asynchronous (ASY) driver
The LIN master node functionality is explained in the below mentioned specification.
LIN: Master Node Data Link Layer
LIN: Master Node Data Link Layer (Appl. Inc.)
Normative reference for LIN

This implementation and the description of LIN data link layer is based on :
LIN Specification Package Revision 2.0 LIN Consortium 2003.

The knock detection is performed for cylinder-individually defined measurement windows
since knock-typical oscillations only occur for certain crankshaft angles. For the time of the
knock window the knock signal is integrated. At the end of the knock window the integrated
signal is sampled and converted to the digital value KNKSx.
The knock window for cylinder x+1 is reprogrammed at the end of the knock window for
cylinder x. The parameters KNKS_CMD_FIL_x, KNKS_CMD_INT_x, KNKS_CMD_GAIN_x,
KNKS_CMD_CONF_x, KNKWB and KNKWE have to be stable at this time. The knock
channel adc is configured for triggering on the end of the knock window. The end of
conversion generates an interrupt in which the parameters for the next knock window are set.
The following picture illustrates this.

(typically 60) teeth, and NC_NR_TOOTH_GAP missing teeth (typically 2) forming the
reference gap (“60-2”). The crankshaft sensor converts the mechanical shape into an
electrical signal.
Magnetic Crankshaft Position Sensors (MCPS) deliver an AC signal with an amplitude
depending primarily on crankshaft speed, and sensor air gap. The signal is shaped into a
rectangular signal by the ECU input circuitry. Each edge of that signal represents a tooth or a
gap of the target wheel. Only signal edges generated from teeth will be processed by
software (active signal edge definition). These may be falling or rising edges, depending on
sensor polarity.
Active Crankshaft Position Sensors (ACPS) switch an open collector output on and off with
every tooth or gap passing. Connecting the sensor output to a pull-up resistor inside the ECU
generates a signal with rectangular shape. Each edge of that signal represents a tooth or a
gap of the target wheel. Only falling signal edges will be processed by software (active signal
edge definition), because they are faster. Design and installation of the sensor must ensure
that falling signal edges are generated from teeth.
The corresponding configuration data is NC_ACT_CRK_EDGE.
The choice is taken in a way not to use the unprecise signal edge generated in the
crankshaft reference gap.
It may be 0 (falling) or 1 (rising) with MCPS, depending on sensor polarity.
With ACPS it should always be 0, because the falling edge is faster due to the sensor’s
open collector interface. The unprecise signal edge in the reference gap is avoided by
choosing the correct installation of the sensor relativ to the target wheel motion direction.
Recurrence:
For set of the RAM as flags, a mirror area is defined which contains a copy of the output and
calibration data in the basic software area (see figure below).
The mirror area of the output data is updated by the lower layer at every active signal edge.
The mirror area of the calibration data is updated by the upper layer each 10ms.

The crankshaft tooth period T_TOOTH is the measured time between two consecutive valid
active crankshaft signal edges (falling or rising according to configuration).
If a missing tooth is simulated, T_TOOTH represents the time period between the last two
real valid signal edges. T_TOOTH keeps the latest value until a new measured value is
available.

2.6.4 System requirements to sensor signal

2.6.4.1 General
With both sensor technologies, there is an angular offset between the mechanical reference
(usually the trailing edge of a tooth) and the timing reference of the sensor (zero crossing of
the MCPS signal, output switching of the ACPS) for an active edge. This offset will further on
be referred to as phase angle. The phase angle depends strongly on sensor tolerances,
installation tolerances (air gap), and operating conditions (speed, temperature).
The tolerances given in the following paragraphs refer to the angular position of the
crankshaft target wheel when an active signal edge is recognized by the input port of the µP,
or to the rotation angle between such events, respectively.

Designation
Document Key Pages

E150-024.49.01 SPE 000 20.0 307 of 5555
2.6.4.2 Relative phase angle tolerances
The usual synchronization algorithms can accept ±3% tolerance of the target wheel rotation
angle between consecutive active signal edges.
e.g. for a “60-2” target wheel, this is 6° (18°) ±0.2°
The sensor/target wheel combination has to fulfill this requirement at all operating conditions.
The permissible accumulation of tooth angle tolerances over a TDC segment is ±0.25% of
the angle for one TDC segment (720°/ NC_CYL_NR) at segment reference conditions.
e.g. for four-cylinder engines 180° ±0.45°
e.g. for six-cylinder engines 120° ±0.3°
Segment reference conditions are: 2000rpm, 80°C.
Please note that for engines with more than 8 cylinders, this requirement is more stringent
than the requirement for consecutive signal edges.
2.6.4.3 Relative phase angle stability
The angle for one TDC period measured under segment reference conditions must not have
a drift > 0.045° versus speed variation from 2000 rpm...7000 rpm and temperature variation
within the complete range. This requirement has to be fulfilled for all tolerances and all
possible displacements of the target wheel relative to the sensor (air gap, radial run-out,
crankshaft flexion, bearing clearance...).
In case of MCPS sensors, phase angle stability must be measured with the ECU hardware
stage.
2.6.4.4 Repeatability
Two different definitions of repeatability are functionally equal. The choice depends on the
sensor test bench and measurement equipment.
1. Phase angle repeatability
(mechanical edge to signal edge for the same tooth) ±0.025°
2. Interval repeatability
(signal edge to signal edge for the same pair of teeth) ±0.05°
In both cases the repeatability is determined from the maximum and minimum value out of a
large number of measurements under constant conditions.
2.6.5 Hardware and HAL requirements
2.6.5.1 EMI
Any signal disturbance must be suppressed as far as possible. Supplemental trigger events
must not be generated due to such disturbance, particularly not at the slow zero crossing in
the reference gap.
2.6.5.2 Phase shift repeatability

At constant operating conditions, the phase shift introduced by the input circuitry must be
constant within ±0.1 µs

• NC_ACT_CAM_EDGE_SYN = 1 or 2: no level detection is performed, only camshaft
edges (falling or rising) are evaluated. This configuration shall be selected when a ACAM
non – TPO or a MCAM sensor is used.
• NC_ACT_CAM_EDGE_SYN = 3: level detection at engine start, falling and rising
camshaft edges are evaluated. This configuration should be selected when a ACAM TPO
sensor is used.
A diagnostic output is delivered to allow detection of camshaft signal failure.
The signal is used for:
1. Self synchronization of all camshafts : timing validation of the active edges of the signal
in correspondance with its theoretic position (used for VVT controler, for detection of
crankshaft signal failure, and for limp-home in case of crankshaft signal failure).
2. Camshaft / crankshaft synchronization of the selected camshaft : determination of the
offset for the engine position calculation
3. Engine position interface for pre-injection (with the selected camshaft used for cam/crank
synchronization)
These three functions are described with three states diagrams.
Recurrence:
For set of the RAM as flags, a mirror area is defined which contains a copy of the output and
calibration data in the basic software area (see figure below).
The mirror area of the output data is updated by the lower layer at every active signal edge.
The mirror area of the calibration data is updated by the upper layer each 10ms.
The output data is copied from the mirror area every 10 ms

The IVVT control consists of the merging of the holding pulse width modulation energisation
and time limited low or high level adjustment pulses. The holding energisation is a system
parameter, which is adapted slightly due to e.g. tolerances. It can be the low level
energisation in some special cases. The adjustment energisations are calculated by the
controller and lead to camshaft movement. Some solenoid valve energisation cases are
shown in figure "Solenoid valve energisation".

Coincidence requirements: ACTION_INFR_SetHoldIvvt starts the holding energisation.

ACTION_INFR_StartPulseIvvt starts a time limited
adjustment energisation. This energisation replaces the
holding energisation.
If the adjustment energisation is over or is stopped by
ACTION_INFR_StopPulseIvvt the holding energisation starts

again.
An active adjustment energisation can be updated by a new

one without a switch to the holding energisation. The update
means a start of a new adjustment energisation.
There is no effect if ACTION_INFR_StopPulseIvvt is called
and there is currently no active adjustment energisation.

2.10 Acquisition of electronically controlled cooling fan signal
The configuration constant NC_ECF_CONF allows to determine the wanted fan control
strategy. In principal it is possible to choose between a RLY- or a PWM-control architecture.
A RLY/PWM fan control strategy in parallel is also existing. In this case the aggregate
architecture allows to switch either the control of RLY-fan(s) or the control of PWM–fan(s)
during ECU runtime depending on the setting of the configuration bit CONF_CFA. The
control of both variants (RLY- and PWM-fan(s)) in parallel at the same time is not allowed.
The following fan control architecture is adjusted:

NC_ECF_CONF = 2 Î control of cooling fan(s) by Relay(s) or PWM(s)
(CONF_CFA = 0 for RLY- control)
(CONF_CFA = 1 for PWM- control)
The configuration bit CONF_CFA is representing the activated control algorithm. Either the
functions for RLY-fan(s) or the functions for PWM-fan(s) are activated. Both control functions
are never activated in at the same time.
For each fan stage as well as each PWM value, a signal at the ECU output stage has to be
generated by the infrastructure to guarantee the link between the calculated signal to the
available cooling fan(s) (hardware component) at the vehicle.
2.10.1 Acquisition of cooling fan signal (RLY version)
Input data:
LV_ACT_ECF[NC_ECF_NR][NC_ECF_RLY_NR] NC_ECF_RLY_NR NC_ECF_NR
In case of a enabled RLY-fan control strategy (refer chapter: “ENTE Configuration data”), a
Boolean is calculated (LV_ACT_ECF[NC_ECF_NR][NC_ECF_RLY_NR) to switch on / off the
requested cooling fan stage(s). For each fan stage a signal at the ECU output has to be
generated by the infrastructure to guarantee the link between the calculated signal to the
available cooling fan(s) (hardware component) at the vehicle.

describe the required functionality.
The I/O software is responsible for opening and closing the injectors in all injection modes
according to the inputs supplied. It is is applicable for HPDI and MPI engines with 3 to 8
cylinders (logical cylinder numbers 0, 1, 2, ...). It must work in an engine speed range from
30 to 8200 rpm.
Two injection pulses per cylinder and working cycle (720 °crk) should be handled.
2.16.1.1 Reference point and injection phase

The fuel can be injected over a range of 720 °CRK. The cylinder individual zero position of
this range is defined via the constants NC_REF_EOI_LIM (defined in I/O SW) and
NC_EOI_LIM (import data) with reference to the ignition TDC of cylinder 0, see figure below.
Related to tdc cylinder 0:
EOI_LIM_x = NC_REF_EOI_LIM + NC_EOI_LIM - x * (720 / NC_CYL_NR)
SOI_LIM_x = EOI_LIM_x + 720 °CRK

2.16.1.2 Calculation of Start of Injection SOI

The start of injection angles SOI_1_x, SOI_2_x, SOI_POST_INJ_x are calculated using the
end of injection angles EOI_1_x, EOI_2_x, EOI_POST_INJ_x and the cylinder specific
injection times TI_1_x, TI_2_x, TI_POST_INJ_x.
EOI_1_x, EOI_2_x and EOI_POST_INJ_x are counted in degrees with reference to
EOI_LIM_x.
The latest engine speed information is used for the transformation between time and angle.

2.16.1.3 Injection and Calculation Updates

Injection is started at the angle SOI_1_x, SOI_2_x and SOI_POST_INJ_x, respectively.
As soon as the trigger TRIG_INJ_UPD / TRIG_INJ_UPD_x is set, the input data are
updated (once per segment).
The trigger TRIG_INJ_UPD / TRIG_INJ_UPD_x is set every time EOI_LIM_x is reached.
Every injection starts earliest at SOI_MAX_x and ends latest at EOI_HOM_x.
Between different injection modes it will be switched with interface INJ_MOD_GLOBAL. It
switches all cylinders at same time to a new injection mode. The INJ_MOD_x interface is
able to switch between single and double injection mode for a single selected logical cylinder
x. These rules will be excepted by pre injection mode, which changes automatically the
cylinder individual pre injection mode to sequential mode with single injection cylinder
individual. – for detail look at chapter 2.16.2.1 Pre injection.
The following injection modes are valid for interface INJ_MOD_GLOBAL:
1. Injection disable mode
2. Sequential injection mode with single injection
3. Sequential injection mode with double injection
4. Pre injection mode
The following injection modes are valid for interface INJ_MOD_x:
2. Sequential injection mode with single injection
3. Sequential injection mode with double injection
2.16.1.3.1 Single Injection
⇒ If the calculation is updated before the injector is opened and the new SOI_1_x has already
passed, the injection is started at once and will be continued for TI_1_x.
(see Figure 2, Injection Update 1)
⇒ If the calculation is updated while the injector is open and LV_ADD_PULSE_x = 1, the
injection time should be increased if
TI_1_x n+1 > TI_1_x n
and should be decreased if

TI_1_x n+1 < TI_1_x n

If the new TI of the pulse has already elapsed the injection

should be stopped immediately.
⇒ If the calculation is updated after the previous calculated fuel amount is already injected
(the injector is already closed) an additional injection pulse should be performed
immediately after the injection update. But only

The additional pulse should be stopped immediately at EOI_MIN.
The injection time should be decreased if
TI_x add. Puls > (TI_1_x n+3 - TI_1_x n+2) * FAC_ADD_PULSE + TI_ADD_DLY

Note: In stratified mode LV_ADD_PULSE_x is always zero.Therefore neither in/decrease of

the injection time nor the additional pulse is performed. In homogeneous mode
LV_ADD_PULSE_x can be set by the application system.

Minimum off-time between two injections NC_T_MIN_INJ_INH is 0.1 ms. For diagnosis the
minimum off-time between two injections has to be 0.25 ms).

2.16.1.4 Priorities for timing of injection
If the different requirements for the injection can not all be fulfilled simultaneously, the
priorities are defined as:
1. The injection shall not start before the beginning of the injection phase (SOI_LIM).
2. The injection shall not proceed beyond the end of the injection phase (EOI_LIM).

E150-024.49.01 SPE 000 20.0 368 of 5555
3. The injection shall not start until the minimum delay NC_T_MIN_INJ_INH has passed
after a previous injection.
4. The actual injection time shall be as close as possible to the desired injection time.
5. The actual end of injection shall be as close as possible to the desired end of injection.
2.16.1.5 Deactivation of cylinders

All cylinders can be deactivated independently. The information is contained in the variable
LV_INH_IV_x which is input for this functionality. The variable is checked at every SOI_x.
If LV_INH_IV_x = 1 the injection is not performed.
At EOI_LIM_x, the deactivation status of the cylinder during the previous injection phase (0
... 720 °CRK) is indicated at the output interface by the variable INJ_StateOfPrevInj_x.
INJ_StateOfPrevInj_x = 1 .... logical cylinder x was injected
INJ_StateOfPrevInj_x = 0 .... logical cylinder x was not injected
In case of double injection: If the first injection is deactivated by LV_INH_IV_x then the
second injection is not performed.
2.16.1.6 Information about actual performed SOI, EOI and TI at the Output Interface
After an Injection was performed, the (cylinder individual) SOI, EOI and TI of that injection is
indicated at the output interface as:

2.16.1.7 Dynamic angular error of SOI and EOI under transient engine operation
The maximum angular error under transient engine operation is defined as follows:
Maximum angular error = f(N, Gradient of N)
The error is measured assuming the engine speed is constant and begins to accelerate or
decelerate at a constant rate. A positive error is defined if the actual angular is smaller than
expected (acceleration error) while a negative error is defined if the actual angular is bigger
than expected (deceleration error).

⇒ Error informations are gathered (or-ed symptom specific) until read out by the application
software ASW.
At the moment when ASW is reading data from I/O software, the I/O software data will
be reset. (It is possibel to have more than one electrical failure symtom reported to
ASW.)
⇒ The cylinder specific variable LV_SCG_VLD_IV_x, LV_SCB_VLD_IV_x,

LV_OC_VLD_IV_x are set to one (valid) if new diagnosis data from hardware are
available.
⇒ If more the one error symptom is detected during the 10 ms readout period, the priority
of the errors reported is:
1. short cut to battery (scb)
2. short cut to ground (scg)
3. open curcuit (oc)
⇒ SCB will shut off the device and the error will be kept by the device until a “off-slope”
occurs.
⇒ SCG, OC: read out of the device erases error status and the device is not shut off.
Application hint:
The minimum injection time TI_MIN has to be calibrated to ensure proper diagnosis (for
diagnosis the minimum injection time is 0.4 ms and the minimum off-time between two
injections is 0.25 ms).

Latest end of injection angle for pre injection
The aim is to pre-synchronise and start the engine as fast as possible. The experience has
shown, that when the engines was switched off, it will stop in the most of the cases at the
same specific engine positions. This information is used together with the information of
relative engine positions PSN_ENG_SYN_MIN and PSN_ENG_SYN_MAX to pre-
synchronise the engine. In the case that the difference of PSN_ENG_SYN_MIN and
PSN_ENG_SYN_MAX is lower than the threshold PSN_DIF_ENG_SYN_THD then the pre
injection will be enabled in the ASW.
Injection phasing for preinjection:

The cylinder individual end-of-preinjection-angle EOI_PRE_INJ [NC_CYL_NR] is calculated
in the ASW and send to the IO SW. All angles are related to engine position. In addition to
that, the angle EOI_MIN_PRE_INJ is used to look for the first cylinder and for the first fuel
injection.
The start of injection angles for pre injection are calculated using the end of injection angles
EOI_PRE_INJ [NC_CYL_NR] and the injection times TI_PRE_INJ [NC_CYL_NR] analog to

chapter “Calculation of Start of Injection SOI”.
The preinjection is carried out by the IO SW in the case that the injection mode is set to pre
injection.
In the case that the injection mode sequential is selected, then the fuel injection will start in
sequential mode directly (this occurs when crankshaft synchronisation is detected by the
ASW). The IO SW is using the standard data set for injection (TI_1_x, ...).

During the pre synchronisation phase it is possible, that the actual engine position can jump
due to hardware events i.e. CAM edge or CRK GAP. The IO- injection – SW has to react on
such changing engine positions and check if any already started injections can be finished
successfully at the latest possible angle EOI_MIN_PRE_INJ. See the four cases in figure 4.

Formula section:
IF Injection mode pre injection is selected
THEN
the following actions has to be executed:
- First injection TI_PRE_INJ [NC_CYL_NR] will be applied with the phasing of

EOI_PRE_INJ[NC_CYL_NR].
- As basis for the EOI calculation the angles are referenced to engine position.
- The latest allowed end of injection for the first pulse is EOI_MIN_PRE_INJ.
- All cylinders will be checked if TI_PRE_INJ [0] can be finished until EOI_MIN_PRE_INJ.
Then choose the earliest cylinder, who’s individual pulse position is before
EOI_MIN_PRE_INJ, For this check it is assumed that the engine speed will not change
during the injection.
- The following cylinders do not need the check of EOI_PRE_INJ because their pulse
positions will be later.
- They are performed with TI_PRE_INJ [1 ... NC_CYL_NR –1] and EOI_PRE_INJ [1 ...
NC_CYL_NR –1] in their logical order.
- For each of the NC_CYL_NR preinjections:

- it is executed immediately if it’s start of injection SOI is already past or it will
be started at it’s determined SOI,
- it will be cut off at EOI_MIN_PRE_INJ at latest.
- After each injection the INJ_MOD_x is changed by the IO-SW to sequential mode
with single injection cylinder individual.
- If an engine position actualisation occurs due to a position jump then the four
following cases has to be checked corresponding to figure 1:

Case I: Injection was not started up to now.

Start with pre-injection at planned reference position.
Stop injection at EOI_MIN_PRE_INJ position or earlier.
Case II: Injection has been started.

Stop injection at EOI_MIN_PRE_INJ position or earlier.
Case III: Injection should be started during singular step.

Start injection immediately and cut at EOI_MIN_PRE_INJ or earlier.
Case IV:Injection happened during singular step.

injection and continue with standard sequential injection, i.e. pre-injection on
this cylinder is missing!

2.16.3 Additional Requirements for HPDI engines
2.16.3.1 Injection pulse lock mechanism for ATIC 21 driver

For the ATIC 21 driver a lock mechanism is needed to prevent overlapped pulses on the two
injectors, which are connected to the same high side driver. After start of a pulse sequence
on one of the two injectors the other injection driver has to be locked for injection pulse
generation. The lock mechanism has to be switched to the other injector, if one of the
following conditions occurs:
- Immediately after finishing the latest possible pulse of the current unlocked injector
plus minimum off-time between to injections (NC_T_MIN_INJ_INH)
- Immediately after reaching the EOI_MIN of the latest pulse for the current selected
cylinder, independent from having carried out or having finished the pulse under
consideration of NC_T_MIN_INJ_INH
After the cylinders are switched the previous cylinder has to be locked – no injection pulses
for the previous cylinder are allowed anymore.

Injector current Fast Decrease Time
The specification refers to the injector driver ATIC 21 in combination with solenoid injectors.
The current to control the injector is variable and can be influenced via the application
software. The current profile is described by
- the “Precharge Time” T_IV_PREC, necessary to limit the energy which comes from the
DC/DC-Converter (ECU integrated) and is needed during the “Peak Hold Time”.
- the “Peak Hold Time” T_HLD_IVP (or boost phase) to guarantee a safe opening of the
injector up to a defined fuel pressure,
- the “Fast Decrease Time” T_END_IVP, which enables a fast reduction of the energy
stored in solenoid coil down to the level of the Hold Current. This guarantees almost a
constant injector closing time (for a certain fuel pressure) down to very short injection
times (~ 0.4 ms) and therefore a better Linerar Flow Range,
- the “Hold Phase” with a constant current, high enough to keep the injector open,
see Figure 5.
The boost voltage is the voltage from the DC/DC-Converter which is active at the injector
from start of injection until the injector current reaches its peak value, see figure 5.

This function sets the angular position of the dwell time turn on in order to have the time to set
up the necessary current in the ignition coil.
The strategy is based on a priority of the ignition angle. If dwell time priority is requested the
minimum dwell time is equal to maximum dwell time.
The strategy respects ignition coils with dual and single outputs. This function could be used
independently of the number of cylinders (n) and the geometry of the crankshaft target wheel.
This function could be used for homogeneous combustion mode and for stratified combustion
mode. The calculation of the spark advance is in both cases the same.
All of the functions described in this section operate over the entire engine speed range.
This specification includes two mode following the IGRE version: PI or PI + DI

Recurrence: engine stop to engine run
Formula section:
In case of CAM failure, the cylinder in combustion cannot be unequivocally identified. Engine
phasing might be wrong. In such a case, a limp home mode function on Ignition is provided
in order to have the possibility to drive the engine. Nevertheless, in this case, since the right
cylinder phasing is not known, Ignition coil have to be driven in Half-Static mode to be sure to
execute at least an ignition on the cylinder in combustion.
Decision to use such Limp Home functionality will depend on the setting of
LC_IGC_LIH_CONF. If LC_IGC_LIH_CONF = 0, no Limp Home is provided in CAM failure
and Ignition is stopped. If LC_IGC_LIH_CONF = 1, then Half-Static Ignition mode is done in
case of CAM failure
If LV_ERR_CAM is active, the ignition coil control will be executed in half-static ignition-coil
control mode if selected by the settings of LC_IGC_LIH_CONF
In such a case (half-static mode activation in CAM failure) the same Ignition and Dwell Time
will be applied to the 2 Crank synchronous cylinders (eg. on a 4 cyl engine, cyl. 1 and 4 and
cyl. 2 and 3 will be fed with the same Ignition and Dwell Time)

2.18 Ignition output diagnosis (for ATM 46 / Combined “ASIC”)
Each ATM46 could analyze 4 ignition coils. If diagnostics for more the than 4 coils are
necessary, a parallel ATM46 has to be used.
The diagnosis is based on ignition coil primary over voltage measurement.
The input signal of the ATM 46 is the IGBT collector voltage.
In case of an ignition system with single output coils, the function does not work in camshaft

The aim of the present function is to protect the ignition power stage against short circuit to
battery (SCP).
The purpose of ignition power stage diagnostic is to detect a short circuit to battery voltage
condition (SCP). At each Dwell Time On event, the ignition power stage is switched on. In
normal condition, the current increase in the ignition power stage is limited by the inductance
of the ignition coil solenoid.
In case of a short circuit to battery, the coil external device does not limit the current in the
ignition power stage. In this situation the current is only limited by the current capability of the
ignition power stage. This power dissipation would destroy the power stage. From the Dwell
Time ON event in SCP condition, the IGBT’s can withstand this overload current only for a
very short time (750µs for IGBT without shunt). So, it is necessary to switch off this IGBT
transistor for safety and protection reasons by software (IGBT deactivation by switching off
the charging command in SW) in case of an overload condition and after a certain time delay
has elapsed (NC_INI_CTR_DEAC). This time delay is necessary in order to filter parasitic
spikes. On the other hand this time delay must not exceed the maximum rating of the IGBT’s.
For ignition power stage diagnostic, the voltage across the ignition power stage is compared
to a fixed threshold voltage. This threshold voltage is chosen to be higher than the maximum
saturation voltage of the ignition power stage during a dwell time in normal operation. If there
is no short to battery voltage condition, the voltage across the ignition power stage drops
below this fixed threshold voltage at each dwell time. In case of a short to battery voltage
failure, this voltage is not (or only for a short time) passed. A micro controller monitoring the
ignition power stage diagnostic output is able to detect this fault.

This ignition power stage diagnostic circuit is designed for an engine management system
including four ignition power stages. This four diagnostic information can be evaluated at one
output by having a logic OR function of them.
After each deactivation from this protection function, the cut off IGBT will be reactivated
again in the next ignition cycle
The function could be used for ignition systems with single-output coils and double-output
coils. The IGBT protection function is cylinder selectively deactivated in case of single-output
coil and linked dual cylinders for ½ static coils.

The ATM46 is used to generate a signal evaluated by the SW for overload condition

To perform the IGBT protection and SCP diagnostic, the BSW provides one functional
service (BSW driver – one driver for one ATM46 protection and SCP diagnostic line)
As only one IGBT diagnosis output signal from the “ATM 46” exists (all channels are linked
by a wired “OR”) and only one BSW functional service (this BSW functional service used is
described in the following paragraph) is used in connection to this diagnosis output signal
line, the function is limited to non-overlapping dwell time pulses. In case of overlapping Dwell
Time, the last TD ON event that occurs will re-trigger the call of this function and thus be

Description:
This ignition diagnosis function evaluates the primary over voltage duration V_DUR_IGC[x]
provided after the ignition coil cut off.
The aim of this spark burning diagnostic function is to measure the spark duration by
detecting the presence of a spark on an ignition plug. The over-voltage at the primary coil of
an ignition solenoid is equal to the voltage across the spark gap of the ignition plug divided
by the transmission ratio of the ignition solenoid and superimposed on the battery voltage.
The time where the voltage at the primary coil of the ignition solenoid is higher than a battery
voltage dependent threshold voltage (VBD_TH) gives the spark duration.
In the moment, when the ignition power stage (IGBT) is switched OFF (ie. at TD OFF event
occurrence), the voltage VC at the collector of the IGBT rises, due to self-induction, and
ignition occurs. As long as the ignition spark is burning, the voltage is well exceeding the
battery voltage.
By means of a hardware defined threshold (VBD_TH; typical value: VBat + 3V) the burn
condition is detected and a matching signal is generated, eg. Here by the combined ASIC
ATM46. This signal is used to measure the overall burning duration.
The Ignition Burning diagnostic signal IGN_DIAG is generated by this combined ASIC. This
time for the burning spark IGN_DIAG is calculated via the duration of the diagnostic signal
staying above the threshold of VBD_TH.

This ATM46 ignition diagnostic circuit is designed for an engine management system
including up to 4 ignition coils/solenoids. This four diagnostic information are then evaluated
on one output by applying a logic NOR function on them. The output signal IGN_DIAG of the
ignition diagnostic circuit is processed by the µP.
Due to combustion chamber turbulence the spark of an ignition plug is not stable. The result
is an unstable primary voltage at the ignition solenoid. Therefore a filter in the output signal
IGN_DIAG is necessary to prevent the µP from high frequency inputs.

2.26.3 Time behaviour
This chapter describes the time behaviour between throttle position signal aquisition, digital
position controller calculation and the PWM output generation ( power stage ).
The aim is to synchronise the TPS aquisition with the controller calculation and the PWM
output generation for minimal time delay.
Description:
The TPS signal determination and the digital position controller are calculated in the 1 ms
ASW task. The AD conversion process ( after every ms ) and the PWM generation are
executed asynchronously to the 1 ms ASW task. The maximum time delay between AD
conversion and PWM generation depend on time jitter between:

- AD conversion and TPS signal determination ( 0 ≤ T1 ≤ 1 ms )

- Position controller calculation and PWM update ( 0 ≤ T2 ≤ 1 / frequency )

The maximum time delay is the summation of T1 and T2 !
( 0 ≤ Tdelay ≤ 3 ms for a frequency of 500 Hz, 0 ≤ Tdelay ≤ 2 ms for a frequency of 1000 Hz )

2.26.5 Power stage error detection
The power stage ( H – bridge IC ) for electronical throttle control is equipped with internal
diagnosis functions. The following errors can be indicated but can not be distinguished by the
software per power stage status flag line.
• Undervoltage / Overcurrent / Overtemperature / H-bridge hardware disable
Description:
The following error detection are done by BSW and ASW if an error occurs. In the case of
errors, the status flag line of the power stage changes his logical level and triggers an BSW
interrupt. The interrupt set a mark for the ASW “ power stage diagnosis “ and switch-off the
power stage. The ASW reads and resets the mark, starts the error debounce and switch-on
the power stage. The error detection is started newly.
After the error debounce, an error is set and the power stage is switched off by the ASW.
The respective ASW functions are executed in a time base of 10 ms.

2.27 ETC Monitoring ECM2 - Requirements to BSW
2.27.1 Requirements concerning ‘Monitoring of engine speed using a software timer’
Output data:

T_SEG_SW O 0 ... FFFFFFFH 0 ... 2.6844e8 1 μs
segment time determined by means of a software timer
The segment time T_SEG_SW is generated by a software timer solution in the BSW. The
software timer is triggered by crankshaft segments and produces time stamps for the trigger
events. The maximum delay between event and time stamp must be less than 300 µs (split
into an invariable part of 50 µs and a variable part of 250µs). From the time stamps the
signal T_SEG_SW is determined; its resolution is 1 µs.
The segment time T_SEG_SW is necessary to generate an engine speed signal that is
independent from N_32 (generated from T_SEG). It is used in the module ‚Monitoring of
engine speed using a software timer‘ of the aggregate ECM2.
Note: Since for the event <Engine Stop> the engine speed N_32 is set to zero in the function
level (and T_SEG is set to its maximum value, respectively), the segment time T_SEG_SW
has to be set to its maximum value for <Engine Stop> as well. However, this action must not
be triggered using the variable LV_ES=0, but must be initialized by the BSW trigger that is
set when the BSW is recognizing the event <Engine Stop>.
Initialisation: max. value

at 1. initialization after <Power On> and
at transition BSW event <Engine Running> ⇒ <Engine Stop>
Recurrence: segment - synchronous

Activation: during every engine state

of 40ms, see "Process Monitoring". To define the scope of the Process Monitoring as wide
as possible, the voltages should be a direct output of the ADCs.
Note: Here only the requirements regarding the Process Monitoring are given. No functional
aspects of the functionalities primarily processing these signals are listed here. Therefore
especially the recurrence may occure with a higher frequency, but the range and resolution

Description:
Voltages of lambda sensors offered by Basic SW are transformed to application system
specific variables.
The error detection is effected via the ECU hardware.
Error informations are gathered (or-ed symptom specific) until read out by the application
software ASW.
At the moment when ASW is reading data from I/O software, the I/O software data will be
reset. (It is possibel to have more than one electrical failure symtom reported to ASW.)
The variables LV_LSH_SCP/SCG/OC_LSH_UP/DOWN[i] are set to one (valid) if new
diagnosis data from hardware are available.
If more than one error symptom is detected during the readout period, the priority of the
errors reported is:
4. short cut to battery (scp)
5. short cut to ground (scg)
6. open curcuit (ol)
⇒ SCP will shut off the device and the error will be kept by the device until a “off-slope”
occurs.
⇒ SCG, OL: read out of the device erases error status and the device is not shut off.

communication with the 8-bit microcontroller. Consult the specification "BIOS SW
Specification EMUSPI" (bemuspi.doc), which is maintained by the software team, for more
information. The application software interfaces with the IO software through the TRL
(transformation layer) via the TRL EMUSPI interface. Consult the specification "TRL SW
Specification EMUSPI" (temuspi.doc), which is also maintained by the software team, for
more information.
Description:
The raw engine off duration, t_es, is produced from a basic timer that is capable of running
while the main CPU is powered-off. The basic timer is deployed on the external 8-bit
microcontroller and can be started, stopped, and reset upon request from the application.
Recurrence: Upon request.
Activation: Upon request.
Deactivation: Upon request

The general mechanism for reading values is to invoke an interface to read the values from
the external microcontroller into the EMUSPI shift register, and then invoke another interface
to read the values from the EMUSPI shift register into the variable. These interfaces are
called upon request from the application software; however, the timing constraints given in
the specifications (bemuspi.doc and temuspi.doc) must be respected.
--- Interfaces involved in getting data ---

Note: * Interface need to be called two times consecutively with Lv_cmd = 0 and Lv_cmd =1,
respectively. Minimum recurrence of these consecutive calls is 5ms. Any other interfaces
must not be called between these two calls.

The decision to inhibit an ignition stage is taken for each output before the turn on at
TD_ON[x]. This means that no Disable / cut off can be set on a coil while charging.
Management of Ignition Cut-Off: Enable / Disable mode of Ignition Power stages

For normal Dwell Time and coil charging management:
a. No Ignition cut is allowed on a currently charging coil, ie. no Disable Command of a
power stage is considered after the TD_ON event
Nevertheless, if the Disable request still be present, it will be applied on the next coming
to fire cylinder
b. Enable command request coming to a power stage in Disable mode will be only
performed if TD_IGC[x] time to IGA_IGC point can be respected/realised.

In other case, this Enable request will be performed only on the next engine cycle

This Ignition Spark Angle change obtained when reaching TD_MIN will be taken into account
and respected by a corresponding change of the coil charging time (the Dwell Time).
But, such a change of the Dwell Time to be thus and then applied can only be processed within

Calculations after starting the dwell time output at TD_ON

For the ignition time there are three main requests for the dwell time output.
1. A minimum dwell time TD_IGC[x] * TD_FAC_MIN has to be guaranteed to ensure ignition.
2. The dwell time has to be limited by a maximum dwell time which is defined as a TD_IGC[x] *
TD_FAC_MAX.
To prevent all cases of big negative engine speed gradients which could destroy the ignition
system, by too long conduction between conduction angle calculation and spark, a timer
limits the resulting conduction time (ignition power stage protection against high current).
The ignition output is turned off immediately at TD_IGC[x] * TD_FAC_MAX (IGA_IGC[x]
could not be respected).

3. In these limits (TD_IGC[x] * TD_FAC_MIN, TD_IGC[x] * TD_FAC_MAX) we have an

absolute ignition angle priority.

1. A Dwell Time Pulse is considered as a main or a multiple dwell pulse. Thus there is no
distinction in the treatment of “Dwell Time On Events” from main and multiple pulses.
2. Consequently, there is no distinction in the treatment of “Spark Events” from main and/or
multiple Dwell Time pulses.
3. A “Dwell Time On Event” defines the start time of coil charging. The resolution and
precision of this time is defined by the corresponding ignition channel
4. A “Spark Event” or “Dwell Time Off Event” defines the end time of coil charging. The
resolution and precision of this time is defined by the corresponding ignition channel.
Each time a “Dwell Time On Event” occurs, the time during which the IGBT_DIAG Pin
indicates a SCP condition has to be integrated within a time window (defined below). If this
integrated time inside this window exceeds NC_INI_DEAC_CTR, the cylinder that has
produced the most recent Dwell Time On event must be switch off as fast as possible for the
current ignition cycle. The time window begins at any “Dwell Time On Event” and ends if
either one of the following criteria is met:
cr.a) another “Dwell Time On Event” from any Cylinder occurs. This restarts the time
window and thus the integration of the time for which IGBT_DIAG indicates SCP
conditions

Designation
Document Key Pages

E150-024.49.01 SPE 000 20.0 438 of 5555
cr.b) a “Spark Event” of the same Cylinder that started charging the coil occurs. “Spark
Events” of any other Cylinder are ignored.
cr.c) the integrated time for which the IGBT_DIAG pin indicates a SCP condition
exceeds NC_INI_DEAC_CTR
cr.d) the time period back to the most recent “Dwell Time On Event” exceeds
NC_IGBT_CUT_OFF_T.
Note that: * in case of overlapping of dwell time periods no short circuit detection can be
guaranty due to HW design and limitation.
* If Dwell Time periods are overlapping, only the most recent one that has the
latest started a coil charging (last and most recent TD ON event, whatever it is) will trigger
the activation of this protection (BSW service) function. Hence, the last occurring TD ON
event will define the coil to be considered by this function and thus diagnosed and protected
(cut off if needed, when SCP failure appears)
With overlapping Dwell Time periods, there is thus a risk to do not diagnose
(and switch off) the correct IGBT in real failure conditions
Dwell Times overlapping conditions may occur, in normal running, with too long
settings of Dwell time in half and full static ignition modes.
Dwell Times overlapping conditions will occur, in Ignition Limp Home running
(ie. ½ static mode usage for coils charging).
One ATM 46 could handle only 4 ignition coils. If there are more than 4 ignition coils 2 ASIC
have to be used. To reduce the possibility of overlapping we have to use them in a crossed
order.

A dwell pulse is considered as a main or multiple dwell pulse, no distinctions are done as
both can be critics in case of SCP failure.
When the collector voltage is higher than the threshold (VIGBT_TH), it indicates a SCP condition
on IGBT. In this case, the IGBT_DIAG signal from the ASIC is high (in SCP level).
a) Events and Actions definition
E1: Dwell Time On Event – Start the charging of the coil

When this event occurs at t1:

- Clear the SCP pulse periods measured up to now (ie. the “SCP condition detected“
integration time)
– start / enable to integrate the time for which the IGBT_DIAG Pin indicates a SCP
condition
E2: IGBT output without SCP condition (t2) or transition to No SCP (t2.2 - SCP disappears)
When E2 occurs, the “SCP condition detected“ integration time is stopped (no or no
more SCP conditions seen)
E3: IGBT output in SCP conditions (t3) or transition to SCP (t3.2 - SCP occurs again)
When E3 occurs, the “SCP condition detected“ integration time is started or re-started
(SCP conditions seen or re-seen again)

E150-024.49.01 SPE 000 20.0 441 of 5555
E4: Cut Event from the IGBT SCP Protection function
E4 will not occur in normal condition when the coil encounters no SCP conditions (no or
too short E3 is met, only E2)
tIPR designates the “SCP condition detected“ integration time acquired (see after)
tIPR is permanently checked when this protection function is active
IGBT Cut Off in case of SCP detection validated:
If tIPR > NC_INI_CTR_DEAC
And (t4 – t1) < NC_IBGT_CUT_OFF_T
Then Switch off the ignition channel that has produced the most recent Dwell Time On
Event (most recent or latest E1 event) as fast as possible
Dwell Time applied in this case will be “tTD realized due to cut off protection”
function and not the “Programmed tTD”
Else No action on ignition channel
EndIf
E5: Spark Event at the cutting of Ignition Coil charging
E5 occurs at t5. E5 / t5 can be either:
- the normal “Programmed tTD” if this SCP protection function has not been reached (no E4)
or
- the Coil charging Time corresponding to “tTD realized due to cut off protection” function if
this SCP protection function has been reached (at E4)
When E5 occurs: the “SCP condition detected“ integration time (tIPR) is stopped
E6: Identical to Dwell On Event E1 for the next following coil coming to charging mode on the
same ASIC diagnostic line
b) Times definition
tipr_on = time period that indicates a SCP conditions (ie. VC > IGBT_TH, the IGBT_DIAG signal
from the ASIC indicates the SCP). During this time, the “SCP condition detected”
integration time – tIPR – is enabled.
tipr_off = time period where no SCP conditions exist (ie. VC < IGBT_TH). This can happen also
in between IGBT SCP diagnosis pulses detection
tTD = time period of any dwell pulse. It correspond normally to the programmed Dwell Time
period for charging the Ignition coil. Here, it can be shortened (cut off of the Coil
Charging) by the IGBT SCP protection function.
tTD OFF =time period between any successive dwell pulses
tCUT_OFF_INH = For the Ignition Coil under SCP Protection diagnostic, the “Cut Off” functionality
is deactivated after a time longer than

tCUT_OFF_INH > NC_IGBT_CUT_OFF_T
If such a time out occurs, the dwell time is not interrupted cause it corresponds to
case where IGBT handles over a situation with a high gradient of battery tension and
not a short circuit to battery
tIPR = “SCP condition detected“ integration time acquired
This Pulse Measurement Method has to be active – which is equivalent to: the
IGBT_DIAG input to the µP at SCP level has to be measured – between t0 and either
criteria cr.a), cr.b), cr.c) or cr.d) is met whichever comes first.
The minimum length of IGBT_DIAG pulses to be detected should be as short as possible
(minimal requirement: 8µs = 2*4µs)

Warning: due different HW and/or µP architecture and implementation constraint limitations
1. Every events E1 to E6 must be processed within a Maximum tolerable time delay
smaller than 50µs
2. The Dwell Time and Dwell Charging period succession should be limited to:
100µs ≤ tTD ≤ 60ms and 100µs ≤ tTD OFF
3. Event E4 = “Switch off the ignition channel that has produced the most recent Dwell
Time On Event” should only occur within 50µs after SCP detection confirmation
4. IGBT_DIAG pulses shorter than 50µs have a risk of not being processed

Diagnosis:
For the Spark Burn Time Duration measurement, the functionality is:
• To ensure a correct measurement in case of spark blow out, only the Active Level of Burn
Time measurement signal from the ATM46 (IGN_DIAG) is integrated in the time window
defined by two consecutive main spark events on the same ASIC
• Active Level of Burn Time measurement signal can be “High” or “Low” depending on HW
configuration
• Minimum length of Active Level pulses to be detected is 50µs and Minimum inter-space
between Active Level pulses to be detected is 50µs. Consequently, IGN_DIAG pulses
shorter than 50µs have a risk of not being processed.
Sparking events from multiple spark pulses do not restart the time window for measurement.
Indeed, the Burning effect that can be created by any Multiple spark pulses is de facto
integrated and cumulated with the Burning Duration from the preceding Main Spark pulse.
At the end of the time measurement window started by cylinder[x], the measured burning
duration is read out and written into the variable V_DUR_IGC[x] for the corresponding logical
cylinder [x]. The time for Burn Time measurement is then cleared and prepared for the next
measurement.
Consider that only one IGN_DIAG signal exists (this IGN_DIAG signal represents a wired
“OR” of all the presents coils channels) which will limit the measurement range.
In Limp Home and ½ static modes, 2 main spark events – on one ATM46 diagnostic signal
line – occur at the same time. This means that the time windows for measurement of (at
least) two cylinders overlap. In such cases, due to the “OR” wiring on the signal information,
only the cylinder on which the most recent main spark event (TD OFF) is produced will define
and will be identified for the time window measurement.
Therefore, the reported burning duration in the interface variable V_DUR_IGC[x] may not
correspond to right real burning cylinder [x] in case of Limp Home mode and ½ static coils.

General Information
For the Acquisition of Battery Temperature and Battery Current there are two possible Sensors.
The Analog Sensor (CONF_BAT_LIN = 0) send the raw values for Battery Sensor (Current and
Temperature) via Analog INPUT. These signals are measured by continuous conversion (10bits)
every 10msec.
The Battery Sensor is a Hall Effect Sensor with a NTC Temperature element. The Hall sensor
provides a voltage Signal, which is directly proportional to the current, which is going in or out of
the battery. According to the characteristic line of the Sensor small voltages shows a negative
current (Battery is discharged) while high Voltage shows positive current (Battery is charged)
The Semi Smart Battery Sensor (CONF_BAT_LIN = 1) send the signals via LIN BUS
communication. The Temperature Signal is already based on a model, which gives the Fluid
temperature inside the battery
To take into consideration the current losses of the battery, the Self discharging current is subtract
from the measured current.

The Analog Temperature Sensor measures the Temperature at the Sensor location. As the Actual
Battery Temperature increased quicker than the Battery fluid temperature a Low Pass Filter is
used. The Initial value is calculated depending on Engine off time, calculated value at engine stop
and Sensor value at start.
For Battery Management it is necessary to know the Battery voltage with higher resolution. This
can be done either with Battery Sensor via LIN BUS communication or via Analog Input signal from
VB_MES.

Formula section:
Segment period acquisition
The function uses consecutive segment times for calculation of a wheel speed gradient. The
segments are built with a minimum number of NC_SEG_TOOTH_RR edges and afterwards
normalized to a length of 4 teeth.
If BIOS_VS_EDGE_CTR - TMP_BIOS_VS_EDGE_CTR_OLD >= NC_SEG_TOOTH_RR
then // If condition reversed, Then and else position interchanged
(calculation of T_SEG_RR_0 )
T_SEG_RR_1=T_SEG_RR_0

Information on ECU state
Input data:
LV_IGK LV_ES LV_MU_INH_PWL_TRAN_ES_EL
The function ECU-state manages detection of the operating states of the ECU and
transitions between them referring to the main inputs key detection and crankshaft
synchronization.
The ECU-state offers system events corresponding to those transitions that can be used by
other functions (e. g. ignition function that asks for ignition reset on the transition engine
running to engine stop).
Those actions are described in the specification chapter of the corresponding functions.
An important value to determine the ECU-state is the value ENG_LOCK_CDN. Here are
stored bit-wise conditions which prevent leaving the ECU-state ENG_LOCK. If anyone of
those bits becomes 1, the ECU-state will become ENG_LOCK. These conditions are:
• cross check of software and calibration data reference

The nominal idle speed in the engine operating state Idle (LV_IS) depends on the additional
loads, coolant temperature TCO and cranking coolant temperature TCO_ST. It is initialized
with the table corresponding to the conditions at the initialization (additional loads).
The input value LV_DLY_N_SP_IS (output from module Converter Torque) is derived from
LV_DRI including a tuneable delay time. If drive is engaged the converter torque is build up
after a short delay time (about 400 ms) if the change in engine speed setpoint for drive
engaged also is delayed the new setpoint can be adjusted more stable.
Following corrections can be done:
- Nominal Idle speed increase for fast Catalyst Heating : If Catalyst Heating function is
active, nominal idle speed offset depends on coolant temperatue (TCO), ambient
pressure (AMP), time after Start (T_AST), and gearbox (A/T, M/T)
- Nominal idle speed increase in case of vehicle rolling (VS > 0) : separate correction for
A/T and M/T
- Nominal idle speed increase in case of high transmission oil temperature for A/T vehicle
- Nominal Idle speed increase in case of low Battery Voltage : correction in Drive for low
Vehicle speed or for M/T vehicle (always active)
In general the transition from a nominal idle speed to another is performed with an adjustable
change limitation IP_N_SP_LGRD.

Offset due to atmospheric pressure

In order to assure manifold vacuum for brake performance in all atmospheric conditions e.g. at
high altitude, it is possible to calibrate an offset to the target engine idle speed dependant on
atmospheric pressure. This offset may be positive or negative. It is added to the final
coordinated idle speed setpoint.
Due to the fact that this offset is applied in all conditions, care must be taken to ensure that all
engine functional requirements are fufilled even with the offset applied.

When speed is falling with high negative gradients at the actual engine speed N with N_DIF
< 0 (overspeed), an interception function should be active to prevent transient effects round
the idle speed setpoint N_SP_IS. These transient effects are normally caused by high
integral part values, which may result from activating the idle speed controller at high speed
deviations. In order to prevent such situations, a corrected setpoint N_SP_IS_COR is
calculated, which intercepts speed when falling into idle range and which leads to small
deviations in speed from the (corrected) setpoint and so to small controller outputs. This
interception function is only active in case of overspeed.
If this function is activated (LC_N_SP_IS_COR_CALC = 1), the N_DIF_COR calculation,

which is described in the following chapter, will be done by the equation N_DIF_COR =
N_SP_IS_COR – N. So, N_DIF_COR will not be calculated by N_DIF-
N_DIF_MMV⋅C_N_DIF_FAC in this case! This means, N_DIF_COR will then not include
the DT1-filtering! See also chapter “Engine speed deviations N_DIF, N_DIF_MMV,
N_DIF_COR”, “N_DIF_COR calculation”.
The calculation of N_SP_IS_COR is depending on the actual value N, figure 1.

C_N_SP_IS_ADD_ACT_MIN, the corrected idle speed setpoint N_SP_IS_COR is calculated as

General Information
This module is calculated segment synchronously or two segment synchronously.
The air mass flow MAF_KGH is determined depending on the presence of an air mass flow meter
in the system.
- If no air mass flow meter is present, the intake manifold model based MAF_THR is copied to
MAF_KGH.
- In a MAF controlled system the measured air mass flow is copied to MAF_KGH.
MAF_DIF is the increase of MAF over the previous segment. In case of two-segment synchronous
operation it is half the increase since the previous calculation.

In the case of rapidly falling load, the transition to (LV_PUC) can be accelerated in order to avoid
an engine speed run-up, which is undesirable. To trigger this function (see the following chapters:
ignition, ignition angle correction for trailing throttle) some load conditions have to be fulfilled.
Hint: The calculation of this module is done synchronously to multiples of a segment.
