Referring to Fig. 2, show high level schematic diagram as the control system 21 of the control system representative that can be used for vehicle 1.A kind of electric system controller 24 of vehicle body computer type is linked in each local control by supplying with common data link 18 (show make the compatible J1939CAN bus of SAE at this), and these local controls also can be for the function executing direct control of most of vehicles 1.Electric system controller (" ESC ") 24 also can be directly connected in selected input and output and other bus.Directly " chassis input " comprise ignition lock input, the input of actuating pedal position, the input of bonnet position and Parking Brake position transduser, these inputs connect into signal are supplied to ESC24.Also there is other input for ESC24.Can use operator's compartment internal bus switch 56 to produce from the signal that PTO controls that is used in the operator's compartment.Operator's compartment internal bus switch 56 is connected in ESC24 via the exclusive data link 64 that meets the SAEJ1708 standard.Data link 64 is that low baud rate data connect, usually on the magnitude of 9.7K baud (baud).5 controllers except ESC24 illustrate and are connected in common data link 18.These controllers are engine controller (" ECM ") 46, drive controller 42, gauge panel controller 58, mixture control 48 and anti-skid brake system controller (" ABS ") 50.The controller that on given vehicle, can have other.Data link 18 is the buses that are used for controller local area network (" CAN ") that meet the SAEJ1939 standard, and under current practice, supports to carry out data transmission up to the 250K baud.It should be understood that other controller can be installed on the vehicle 1 is communicated with data link 18.The wheel velocity signal from sensor 54 is controlled and received to abs controller 50 to the application of drg 52 usually.Wheel velocity via data link 18 writes down and is monitored by drive controller 42.

Vehicle 1 shows the parallel hybrid electric vehicle of making working power system 20, and wherein any or two s' output can be connected in drive wheel 26 in combustion engine 28, electrical motor and the electrical generator 32.Combustion engine 28 can be a diesel motor.Such as other full mixed system, this system's intention is caught the moment of inertia of vehicle again in braking or reduction of speed process.In braking or reduction of speed process, 32 conducts of electrical motor and electrical generator move from the electrical generator of wheel, and with the electrical power storage that is produced in battery.Afterwards, the electric power of being stored can be used for driving motor and electrical generator 32, perhaps combustion engine 28 is replenished and replace combustion engine 28, to prolong the scope that the vehicle traditional fuel is supplied with.Power system 20 is hybrid power design-calculated particular variant, and this is modified to PTO and provides from combustion engine 28 or from the support of electrical motor and electrical generator 32.When combustion engine 28 was used for PTO, this internal combustion function was moved with actv. takeoff output level, and was used to support PTO to operate and make electrical motor and electrical generator 32 with its generator mode operation simultaneously, came traction battery 34 is recharged.Usually, compared with the takeoff output that is provided with effective combustion engine 28 throttles of heat, PTO uses and consumes lower power.

Electrical motor and electrical generator 32 are used for through using drive wheel 26 to come driving motor and electrical generator 32 catching again in moderating process the kinetic energy of vehicle.At this moment, self-acting clutch 30 is thrown off driving engine 28 and electrical motor and electrical generator 32.Driving engine 28 can be used for supplying with power and produces electric power and operate PTO system 22, can be used for for drive wheel 26 provides prime power, perhaps can be used for providing prime power and makes generator operation produce electric power.In PTO system 22 is under the situation of high-altitude lift unit 2, and when vehicle ', this PTO system can not operate, though the description of this paper supposes that in fact vehicle can stop to carry out EPTO, other PTO that does not do like this uses and also can exist.

Power system 20 is in response to by the electrical motor of vehicle energy power reverse drive and electrical generator 32 and catch kinetic energy again.Survey and manage the conversion between effect of ormal traction motor and the negative traction motor effect through mixture control 48.In braking procedure, electrical motor and electrical generator 32 produce electric power, and this electric power puts on traction battery 34 through inverter 36.If mixture control 48 is paid close attention to abs controllers 50 data link communications, thereby when starting regenerative brake, confirms whether the regenerative power braking can increase or aggravate the wheel slip situation.Data communication on the drive controller 42 detection data links 18, and will be delivered to mixture control 48 as these data via data links 68 of application controls signal.In braking procedure, electrical motor and electrical generator 32 produce electric power, and this electric power puts on traction battery 34 through mixing inverter 36.Some electric power can shift from mix inverter, to keep the electric charge of 12 volts of DC chassis batteries 60 of tradition through the DC/DC inverter 62 of step-down.

Traction battery can be only power storage system that is used for vehicle 1.In the application's vehicle of the same period, still generally use various 12 volts of application, and vehicle 1 can be equipped with parallelly connected 12 volts of systems and comes support unit.For the purpose of simplifying the description, and the possible parallel system of not shown this kind.Comprise this kind parallel system also to allow to be used for automobile and design-calculated is easy to obtain and cheap parts, for example be used to the filament bulb that throws light on.Yet, use 12 volts of parts can the cause vehicles weight to increase the weight of and comprise extra complexity.

Electrical motor and electrical generator 32 can be used for extracting electric power and propelled vehicles 1 through inverter 36 from battery 34, and this battery supplied 3 is the electric power of 340 volts of mean effective powers (rms power) mutually.Battery 34 is called traction battery sometimes, come to distinguish with secondary 12V lead-acid battery 60, and this secondary lead-acid battery is used to each Vehicular system power supply.Yet the big utility vehicle of quality is more much lower than roadlice from the gain meeting that the rotary action of hybrid power obtains.Therefore, the electric power of being stored also is used to EPTO system 22 is supplied power.In addition, open the beginning during position when ignition device is in, electrical motor and electrical generator 32 are used for start the engine 28.Under some situations; Driving engine 28 is used for being at driving device 38 that driving motor and electrical generator 32 come battery 34 is charged to produce electric power under the situation of neutral state; And/or cooperate with PTO system 22 and to produce electric power, in order to battery 34 is charged and operates PTO system 22.This can take place in response to the PTO system that extracts the bad consumption of electric charge on the battery 34 22 uses.Usually, driving engine 28 only has than is used to and operates the much bigger output capacity of PTO system 22.So because the no load losses that can produce in the driving engine or the no-load losses that when intermittent operation, can produce, thereby at full time driving engine to be used for direct drive PTO system 22 can be suitable poor efficiency.Can obtain higher efficient through following mode: driving engine 22 is moved near its specified output the time; Battery 34 is recharged and is that PTO provides power, then with tail-off and use battery 34 to come as 32 power supplies of electrical motor and driving engine with operation PTO system 22.

High-altitude lift unit 2 is examples of a system, and this system can only be used by the staff by accident, at first to promote its well-bucket 5, reorientates this well-bucket then.Use traction motor 32 to operate air-lift unit unit 2 and can avoid making driving engine 28 zero loads.If battery 34 is in the state of relative discharge, driving engine 28 can periodically move battery is recharged with effective velocity.Confirm the charge condition of battery 34 through mixture control 48, this mixture control 48 is sent to drive controller 42 with this information via data link 68.Drive controller 42 also can come requirement ESC24 to cooperate with driving engine 28 through the information of issuing ESC24, and ESC24 requires (that is, engine starting and danger signal) to send to ECM46 power operation again.The availability of driving engine 28 (or hardwire) interlocking of can programming based on some, bonnet position for example.

Power system 20 comprises driving engine 28; This driving engine and self-acting clutch 30 are connected in series; Driving engine and be not used in motive power or and be not used in when battery 34 recharged, this self-acting clutch makes driving engine 28 to throw off with the remainder of power system.Self-acting clutch 30 directly is connected in electrical motor and electrical generator 32, and this electrical motor and electrical generator 32 also are connected in driving device 38.Driving device 38 also is used for the power from electrical motor and electrical generator 32 is imposed on PTO system 22 or drive wheel 26.Driving device 38 is beidirectionals and can be used for being back to electrical motor and electrical generator 32 with failing from the energy of drive wheel 26.Electrical motor and electrical generator 32 can be used for (individually or with driving engine 28 cooperation ground) provides motive power for driving device 38.When the electrical generator, this electrical motor and electrical generator supply power to inverter 36, and this inverter can be supplied with direct current (DC) and comes battery 34 is charged.

Control system 21 implements to be used for describing just now the cooperation of the control member of operating.ESC24 is from user's reception and throttle position, brake pedal position, input and PTO input that fired state is relevant, and sends them to drive controller 42, and this drive controller 42 is transferred to mixture control 48 with signal again.Mixture control 48 confirms based on available battery charging state whether combustion engine 28 or traction motor 32 satisfy power demand.Mixture control 48 produces appropriate signal with ESC24 and puts on data link 18,,, then indicates with great takeoff output and operates driving engine if open driving engine driving engine 28 opening and closing in order to indication ECM46.The joint of drive controller 42 control self-acting clutchs 30.Drive controller 42 is also controlled the state of driving device 38 in response to driving device press control 72; Determine whether to put into gear or driving device is delivered to the Hydraulic Pumps that drive wheel 26 still is delivered to as PTO system 22 part with driving torque and (perhaps makes as Hydraulic Pump at driving device 38; Be the pressurized hydraulic fluid of PTO system 22 simply), confirm perhaps whether driving device is in neutral.In order only to describe, vehicle can be equipped with more than one PTO system, and uses the secondary pneumatic system of a plurality of electromagnetic valve components 85 and pneumatic PTO device 84 to show and do to be under the direct control of ESC24.

The control of PTO22 is carried out through one or more remote power modules (RPM) usually.The remote power module is the data link bonded assembly expansion input/output module that is exclusively used in ESC24, and ESC programmes and uses these modules.As under the situation of PTO controller, they can be configured to provide hardwire output 70 and hardwire input at RPM40, and they use and offer load/air-lift unit unit 2 by 22 in PTO device and from this load/high-altitude lift unit 2.To impose on exclusive data link 74 for the request and the location records of motion from high-altitude lift unit 2, in order to be transferred to ESC24, this ESC converts them to for other controller particular request, for example for the request of PTO power.ESC24 also can programme, and comes through PRM40 the valve state in the PTO device 22 to be controlled.At U.S. Patent number 6,272, the remote power module has more completely been described in 402, this patent transferred present assignee and with referring to mode include this paper in.When writing ' 402 patents, " remote power module " that this paper referred to is called as " remote interface module ".Can be susceptible to, provide the TEM of PTO function can vehicle customization become or be equipped to have RPM40, to support PTO and to provide bus switch 57 to connect RPM40.TEM generically is called " carriage builder ", and is called " vehicle body power command signal " from the RPM40 of the carriage builder of being arranged to provide vehicle functions.

Vehicle body power command signal can receive because the influence of the deterioration on the vehicle control device local area network, vehicle damage or system conflict.Therefore, a kind of alternative mechanism is provided, comes from traditional Control Network of vehicle, to produce the power command signal that is used for PTO.The tradition control that under the condition of not using RPM40, provides a kind of mode of this kind power command signal to be to use vehicle as the operator comprises producing the control that is called " chassis input ".The power command signal that is used for the PTO operation that is derived from this kind alternative mechanism is called " chassis power command signal ".An example of this kind chassis power command signal can be when using Parking Brake, to make headlight flicker twice, and perhaps other is remembered but the mode of seemingly special control usage easily, as long as the control selection does not comprise the RPM40 that PTO is special-purpose.

Turn to Fig. 8 A-D now, the hybrid electrically system 800 with PTO driving hydraulic efficiency pressure system is shown.Hybrid electrically system 800 with PTO driving hydraulic efficiency pressure system comprises combustion engine 802, electrical motor and electrical generator 803, PTO804 and first Hydraulic Pump 806 and second Hydraulic Pump 808.PTO804 is suitable for receiving the power from combustion engine 802 or electrical motor and electrical generator 803.PTO804 drives first Hydraulic Pump 804 and second Hydraulic Pump 808.

Shown in Fig. 8 A-D, first Hydraulic Pump 806 is the fixed displacement Hydraulic Pumps such as vane pump, and second Hydraulic Pump 808 is the variable displacement hydraulic pump such as piston pump.

Second Hydraulic Pump 808 has control motor 810 and/or control electromagnetic valve 812, comes the adjustment of the variable displacement setting of second Hydraulic Pump 808 is controlled.Control motor 810 can be electrical motor, electromagnetism stepper motor and so on.Control electromagnetic valve 812 can be electromagnetic type electromagnetic valve device and so on.

What can imagine is, it is that first Hydraulic Pump 806 provides power that combustion engine 802 can be used for driving PTO804, and electrical motor and electrical generator 803 to be generally used for be that second Hydraulic Pump 808 provides power.The load level that is placed on the hydraulic efficiency pressure system 805 is depended in the use of first Hydraulic Pump 806 and second Hydraulic Pump 808 usually.Bigger hydraulic load can use first Hydraulic Pump 806 that is driven by combustion engine 802, and less hydraulic load can use second Hydraulic Pump 808 that is driven by electrical motor and electrical generator 803.

Combustion engine is suitable for the engine speed from about 700RPM to about 2000RPM moment of torsion being supplied to Hydraulic Pump 806,808.Yet electrical motor and electrical generator 803 produce higher torque level with the operating speed less than about 1500RPM.Therefore; When using electrical motor and electrical generator 803 to move second Hydraulic Pump 808 via PTO804; If the hydraulic load on the hydraulic efficiency pressure system 805 need make electrical motor and electrical generator 803 to be higher than the speed operation of 1500RPM, then the second hydraulic pressure capacity of pump is adjusted into bigger discharge capacity.Control motor 810 and/or control electromagnetic valve 812 increase the discharge capacity of second Hydraulic Pump 808, make that electrical motor and electrical generator 803 can be with the flow of hydraulic fluid and pressure feed to the hydraulic efficiency pressure systems 805 of abundance, simultaneously also with the speed operation less than 1500RPM.

Similarly,, then can the discharge capacity of second Hydraulic Pump 808 be adjusted into less discharge capacity if the load in the hydraulic efficiency pressure system 805 reduce, but and electrical motor and electrical generator 803 reductions of speed to the speed below the 1500RPM.
