Into the special microcontroller of gasoline engine ignition Isobarically Control.
Driving circuit enhances driving of the control circuit to booster circuit, which can also be included in control circuit or boosting
In circuit, certain booster circuits may be directly driven by control circuit.
The operating mode factor of engine makes demand of the engine to ignition energy have large change.Burning quality, engine effect
The performances such as rate, Wen Sheng, discharge can change with ignition energy requirement and the balance provided.The demand factor of ignition energy has more
It is a, you can be multifactor compensation.Consider that operating mode factor makees energy balance control, abbreviation energy balance or operating mode balance.It is existing
Technology can also have operating mode factor compensation ignition voltage or tank voltage, but be on the basis of no acquirement accumulator constant pressure
Or be not to be carried out on the basis of determining tank voltage, the certainty of compensation reduces.Also not to booster circuit or energy storage electricity
The quantitative control technology of pressure.Therefore the multifactor compensation of the prior art is qualitative contrlol, is not belonging to energy balance control alleged by this case
System.

Compensation, compensating action determine, form tank voltage and accurately quantify, Cycle by Cycle provides corresponding ignition energy by engine operating condition
Amount.Operating mode balance control is to adjust ignition voltage or ignition energy, considers engineering experience, operating mode balance control technology only need to be with storage
It can voltage target in order to control.
Isobarically Control and operating mode balance control are all the quantitative control technologies of ignition energy, and the latter is the optimal control of ignition energy
System, the control of general name energy balance are the full ripe gasoline engine ignition circuit of a new generation and control method.
Accumulator voltage substantially up to standard is designed, which can meet operating mode of the tool compared with low energy demand.Design is surveyed
Sample resistance partial pressure or comparator reference of circuit etc. is measured, after tank voltage rises to voltage substantially up to standard, detection circuit is sent out
Substantially signal up to standard., need to be after signal substantially up to standard and for the big engine operating condition of energy requirement, then keep booster circuit one
Fixed operation duration, just makes tank voltage reach requirement.This obtains various influence factors to ignition energy for energy balance control
The space of demand adaptation, allows ignition energy to be balanced from different duty requirements.
Operating mode factor includes acceleration, rotating speed, center housing temperature or coolant water temperature, throttle opening or gas flow etc..Increase
Add one to multiple road correlative factor detection circuit, be referred to as auxiliary detection circuit, respectively connect control circuit, transducing signal can be electricity
Pressure, electric current or digital signal and signal of communication.Control circuit Test Cycle factor parameter value, correction-compensation amount(Or it directly determines
Required tank voltage), that is, correct booster circuit is run after signal substantially up to standard angle or duration.Rule is corrected to follow by engineering
Compensated curve or table that experience obtains etc..Such as auxiliary detection circuit is when detecting that center housing temperature is very high, ignition energy or point
The offset of thermoelectricity pressure can reduce, i.e., stop the operation of booster circuit earlier after signal substantially up to standard, make accumulator
Voltage is less after signal up to standard to be risen or no longer rises, and vice versa.Control circuit obtains electricity substantially up to standard before compensation starts
Signal is pressed, tank voltage has reached certain certain value, and determining compensation rate, value are then provided according to duty parameter and compensation model again
Voltage up to standard is subtracted equal to required ignition voltage under the operating mode value.Various compensation factors can be with certain rule superposition or selection highest
Compensation.The realization of compensation can refer to known boosting curve.It, can be simply according to required compensation such as using straight line as ascending curve
Voltage and rate, after the voltage substantially up to standard corresponding moment substantially up to standard, continue booster circuit run time, complete mend
It repays.
Booster circuit provides enough energy and using after Isobarically Control technology within the period for accumulator, rotating speed not into
The factor provided to influence energy, but rotating speed can still be used as a kind of operating mode factor, and tach signal is obtained from ignition signal.
The boost charge rate of booster circuit is related with cell voltage, this is unrelated with the effect of Isobarically Control in this case, but
It is balance condition demand required fortune after voltage substantially up to standard reaches to influence to be booster circuit the time required to compensation in operating mode balance
The row time.Operating mode balance is it is contemplated that this influence factor.Tank voltage from initial rise to voltage up to standard substantially need when
Between, claim basic reaching standard time, in the case where other factors are constant, which is determined by cell voltage.The time is measured, by this
Factor is added in aforementioned compensation operation, can improve the quantitative control technology i.e. operating mode balance control of booster circuit.
Period starts booster circuit, that is, starts to measure this basic reaching standard time, until voltage substantially up to standard reaches
It completes to measure afterwards.Period voltage substantially up to standard and a upper period by detecting obtained basic reaching standard time, calculate energy storage electricity
It is compacted the border rate of rise.It can be by the various influence eliminations to tank voltage rate of pressure rise including cell voltage.In energy storage electricity
Before pressure is substantially up to standard, Test Cycle parameter is gone back, calculates corresponding tank voltage, be voltage substantially up to standard further according to required compensation rate
It to tank voltage and boost slope corresponding to operating mode, calculates and is compensated for operating mode, the time continued to run with needed for booster circuit is i.e.
The time required to compensation.Tank voltage measuring circuit can also be set again, that is, increase another and interrupt detection, benefit is calibrated in operation
The slope of section is repaid, then it is more accurate to compensate.Voltage difference divided by corresponding time between secondary interruption, are compensated slope over 10.
The time required to starting to continue compensation after tank voltage signal substantially up to standard, stop booster circuit after the completion of delay,
Compensation is completed.
Thus a kind of method that tank voltage climbing speed is calculated using voltage measurement up to standard is generated, step is to start boosting
Circuit starts timing, treats that tank voltage reaches voltage up to standard, obtains the time of its experience, calculates rate of pressure rise.This measurement
Calculating does not need to each period progress.According to rate of pressure rise, operating mode factor can be compensated such as preceding method.Or it directly controls
Tank voltage processed, and final tank voltage can be higher or lower than voltage up to standard.
It is often feasible using A/D converted measurement tank voltages.Stablize rising by the output of measuring circuit is filtered.
The measuring circuit analogue value exports connection control circuit A/D conversion inputs, is converted using high-speed a/d.It is held after booster circuit startup
Continuous monitoring tank voltage, i.e., judge whether to arrive the corresponding ignition power of voltage or duty parameter value up to standard after each conversion end
Whether pressure is completed with interruption or inquiry judging conversion.If do not complete, immediately restarting conversion, to required voltage after stop rise
Volt circuit can control tank voltage to desirable value.Operating mode balance is then controlled ignition voltage needed for operating mode as tank voltage
Desired value.Without considering the survey calculation of boosting curve.
Using A/D converted measurement tank voltages, it is possible to be interfered by tank voltage rising.It invents and a kind of is converted with A/D
The method that method measures tank voltage climbing speed, without interruption.Period starts booster circuit, after certain time such as 2ms
Stop boosting.Start the tank voltage value of A/D converted measurements at this time.Tank voltage climbing speed can be calculated.It is being risen
After pressing rate, tank voltage is controlled using rate of pressure rise, process is:Start booster circuit, when starting boost gauge, survey simultaneously
Duty parameter is measured, corresponding tank voltage is calculated and calculates tank voltage using given rate and rise to operating mode respective value and taken
Between, with constant pressure value and rate calculations time if for Isobarically Control.After pressure rising time reaches, stop booster circuit.
Regardless of whether using energy balance technology, the power of booster circuit is often rich to igniting demand or significantly rich
, energy balance control can make booster circuit early out of service, reduce booster circuit run time.This is past from time of ignition
Toward can be up to time of half of light-off period or more.Light-off period can be postponed and start rear booster circuit operation, terminate boosting
Moment is connected with time of ignition.This eliminates tank voltage and is leaked through measuring circuit or other leakage paths, keeps tank voltage,
Accumulator can be substantially reduced averagely to multiply by voltage.The initial time of booster circuit boosting is controlled, optimal Startup time is claimed to control.
Period starts rear booster circuit suitably delay or not delayed startup, and when continuing to detect voltage up to standard and monitoring igniting
It carves.If tank voltage is first up to standard, booster circuit is made to start in next one chronomere of cycle delay.If time of ignition arrives first
It reaches, then previous unit is put forward in next period and is started.
The present invention is on the basis of existing gasoline engine DC ignition road, sets measuring circuit, measures tank voltage, control
Booster circuit processed, making tank voltage, the period obtains balance one by one with igniting demand, realizes that constant pressure igniting and Cycle by Cycle are needed by operating mode
Ask igniting.The various applicable circuits of the prior art and certain improvement variation, are combined with this case circuit feature or method characteristic,
It is within the scope of the present invention.Follow-up limited example is only wherein several preferred.
Advantageous effect:It is unbalanced that Isobarically Control technology completely solves the long-standing ignition voltage of gasoline engine CDI igniting
Significant technology issues.In certain cell voltage such as more than 8-10V, rotating speed per minute 10,000 turn hereinafter, keep ignition voltage
Perseverance is less than 3% for design value or fluctuation.Tank voltage is unrelated with rotating speed and cell voltage and eliminates the discrete of booster circuit performance
Property.When service condition deviates larger, then ignition voltage fluctuation is greatly reduced.
Operating mode balance control follows engine operating condition to change on the basis of Isobarically Control, and ignition energy Cycle by Cycle presses operating mode
Demand quantitatively provides, and completely solves gasoline engine ignition, and permanent technical barrier cannot be accurately configured in ignition energy by operating mode.Storage

Set, control circuit can also imitate the close function of chip microcontroller under conditions of no microcontroller with digital circuit.
This example control circuit uses 89C52, using Duty ratio control formula booster circuit.P1.0 connection driving circuits.It is comprehensive
Consider Different Work Condition of Engine, it is unified to determine that voltage or the corresponding tank voltage of energy claim voltage and comparator up to standard needed for igniting
Circuit parameter.Control circuit sends out the control signal with certain duty ratio, and through driving circuit, that is, resistance, triode T2 is reached
The control terminal of booster circuit makes the electronic switch K1 break-makes of booster circuit, intermittently makes the primary of the transformer B1 of connection battery
Turn-on current.Transformer secondary output induces high pressure, charges through diode D1 to accumulator, and tank voltage gradually rises, until
Voltage up to standard, comparator output switching activity, control circuit detect signal up to standard.The booster circuit should have sufficiently large output work
Rate makes accumulator obtain voltage up to standard in light-off period.Microcontroller stops booster circuit after signal up to standard is received
Boost conversion stops charging to accumulator, and tank voltage is controlled in the voltage up to standard of design.Microcontroller is preferably with interruption
Mode receives signal up to standard.
The effect of measuring circuit is signal transformation, and the high pressure conversion of accumulator the simulation of circuit compatibility or is patrolled in order to control
Collect signal.This example measuring circuit connects accumulator and the interrupting input mouth P3.3 of control circuit, and included analog comparator.Have
Bleeder circuit accesses the backward end of analog comparator after being sampled to tank voltage, end is equipped with reference voltage in the same direction.Pass through design
It determines to reach tank voltage when igniting requires, divides when comparator reference so that after booster circuit starts boosting, energy storage
Voltage reach design requirement i.e. voltage up to standard when, comparator overturning, control circuit generate interruption.As described above, detect interruption
After generation, control circuit stops booster circuit operation through driving, and tank voltage stops rising, and up to next period just opens again
It is dynamic.The adjusting process makes tank voltage rise to constant value up to standard before time of ignition.
The implementation principle of generation and the igniting of time of ignition inherits the prior art, and operation principle is independently of energy balance
The principle of control.The ignition trigger signals of P3.2 connection Transistor-Transistor Logic levels therefrom obtain engine or magneto movement state information,
After making Optimum spark advance angle amendment, in due course through port P1.2, control firing circuit igniting, and electricity is exported to external high voltage package
Stream, the spark-discharge for connecting it.TTL trigger signals come from motorcycle ignition trigger, and through pulse shaper.Shaping

In addition to start stop mode, its output of control signal dutyfactor auxiliary adjustment also can be used in booster circuit.
P3.3 mouthfuls of microcontroller persistently detects storage capacitor voltage through measuring circuit.Tank voltage reaches what design determined
Voltage up to standard samples, comparator circuit through partial pressure, and microcontroller is made to generate interruption.Microcontroller changes output control signal immediately, stops
Only controllable boost conversion is to stop the energy output of this period circuit, and tank voltage stops rising.If in entire charge cycle
Or close to all end of term to be not detected tank voltage up to standard, illustrates that the output of booster circuit energy is likely lower than igniting demand, it is controllable to rise
For volt circuit because having expired the period or closely having expired cycling, control circuit is difficult operation duration, Bian Kezeng in the period for increasing the circuit
Add one unit of duty ratio of boost conversion waveform, increase booster circuit output, tend to balance with igniting demand.And if than
It interrupts compared with device and is occurred to early in charge cycle, it is such as early to the 1/4 of the period, illustrate that DC voltage booster circuit output power is much larger than point
Fiery demand power is more, and microcontroller can reduce by one unit of duty ratio of boost conversion waveform, make voltage up converting circuit output work
Rate reduces, and keeps its higher transfer efficiency, while tank voltage and ignition voltage are kept constant.
Fig. 8 is under different equilibrium state, changes operation duration and makees energy balance control i.e. each parameter of Isobarically Control or signal
Time diagram.Adjustable booster circuit is influenced by cell voltage, and charging pulse amplitude shown in open circuit output i.e. can change, right
Accumulator charging rate also respective change.A arranged side by side, B, tri- small figures of C represent respectively under different booster circuit states, constant pressure
During control or energy balance, the sequential of each parameter or signal.Abscissa is period or magneto rotation angle, is represented with r, is indulged
Coordinate is voltage.In each figure, accumulator voltage is gradually risen to 200V, and corresponding sampling voltage also accordingly improves,
Respectively to Ka, 3 points of Kb, Kc, the partial pressure value of sample circuit has all arrived the analog comparator overturning threshold level 2.5V of setting, and
Corresponding magneto corner ra, rb, rc, it is different due to booster circuit state difference, it represents under different charging rate, can increase
The work duration of volt circuit is different, but all i.e. out of service, storages after the 200V during accumulator value up to standard is this legend is reached
It can voltage constant.Upward arrow represents, after accumulator voltage reaches scale value, makes itself to stop rising through a series of feedback
Process:It is increased in accumulator voltage, after making sampling voltage to the 2.5V set, the voltage up control signal of microcontroller stops,
Adjustable booster circuit is caused to stop transport, charging pulse disappears, and accumulator voltage stops rising.Treat that microcontroller sends out ignition control signal
Afterwards, accumulator energy discharges, loss of voltage, and light-off period completes tour, into next light-off period.
Fig. 9 is under different booster circuit states, changes each parameter of duty ratio auxiliary Isobarically Control or signal sequence schematic diagram.
Under different booster circuit states, accumulator voltage reaches desired value, that is, A, in each figure of B, C the time required to 200V positions or magnetoelectricity
Machine rotation angle is different, is ra, rb, rc respectively in A, each small figure of B, C.Small figure B, because of charging pulse voltage height, pulse
Duty ratio reduce.Small figure C, charging pulse voltage is low, compared to A, improves duty ratio.The change of charge pulse duty cycle
From control circuit, it is compensated the possible deviation of accumulator voltage.
The control of the optimal Startup time of booster circuit may be used.
Delay value refers to controlling cycle and originates the time interval started to booster circuit.Start in the period through certain time-delay or not
Delay starts booster circuit, while continues to monitor analog comparator interruption, waits signal to be targeted, and wait for time of ignition simultaneously
It arrives.If receiving signal up to standard in waiting period, into interrupt routine, delay value plus a unit backed off after random are interrupted, waited for
Time of ignition, and the delay that will make in next period increases, booster circuit operation duration is shortened.If conversely, until time of ignition still
Analog comparator interruption is not received, represents that tank voltage does not rise to voltage up to standard before ignition, delay value should be subtracted one
Unit, next period can shorten delay.Booster circuit operation is simultaneously stopped, performs igniting, this light-off period terminates.
Figure 11 is to whether there is the tank voltage curve comparison schematic diagram of boosting initial time control.It is divided into half range A, no startup
The tank voltage curve of moment control.Lower half good fortune B, the tank voltage curve under initial time control.A shows, different electricity up to standard
Boost process is depressed respectively in M, n-hour terminates, and has distance with time of ignition.Cause damage of the tank voltage after charging
Consumption.Figure B then shows that under different voltages up to standard, initial time becomes P, Q respectively, and finish time is made to be connected with time of ignition.
The control of the optimal Startup time of booster circuit makes tank voltage avoid leakage loss after charging, keeps balance
Control data improves balance control technology index, can make the supplementary means of balance control.Firing circuit efficiency is also improved, significantly
Reduce the average voltage that device is born.
Remaining explanation of this example sees below continuous each example.
Example 2:With reference to figure 3, band current limliting driving duty cycle signals control boosting constant pressure firing circuit.Including control circuit,
Firing circuit, accumulator, driving circuit, booster circuit, measuring circuit and pulse shaper.Control circuit uses
PIC12F615 controls booster circuit using duty cycle signals.The output of the INT ends connection pulse shaper of microcontroller, GP5
The input of driving circuit is connected, output connects the control terminal of the boosting rectifier control end TIP122 of booster circuit.Driving circuit includes electricity
Resistance and each one of diode, also step-up transformer primary current limiting circuit, by R1 to primary current samples, triode T1 is anti-
It is fed to driving side.
Measuring circuit is a pair of of divider resistance, and partial pressure output connects the CIN0- ends of microcontroller, that is, simulates more reversed input
End.Signal is changed into logical value by the analog comparator in microcontroller.Divide the when setting of internal simulation comparator reference with
It designs tank voltage or voltage up to standard is related.
Microcontroller ignition pulse signal can be measured with interrupt mode and internal simulation comparator exports, and light-off period is opened
Begin, booster circuit starts, and tank voltage rises.When accumulator voltage reaches voltage up to standard needed for primary igniting in the period,
Analog comparator output logical value variation, comparator, which interrupts, to be occurred.The GP5 ends of control circuit keep output low level, boosting electricity
Road is out of service, and tank voltage stops rising.After moment to be fired arrives, GP4 ends output high level, ignition switch circuit closes
It closes, accumulator releases energy, and high voltage package is through external spark-discharge.This light-off period using time of ignition as the beginning and the end terminates, and is
For constant pressure firing circuit.
Using other single chip circuits, the mouth line of PIC12F615 need to be only replaced with the mouth line of identical function.During INT ends are used
Disconnected input port replaces, the general delivery outlet of GP4, GP5, and comparator input terminal is simulated in CIN0- pieces, forward and reverse to occupy microcontroller
Characteristic selects.
This figure firing circuit is connected between accumulator and high voltage package, the other end ground connection of accumulator, that is, storage capacitor.
Electric current flows to high voltage package primary coil with entering from accumulator through firing circuit during igniting, and high voltage package secondary high pressure is through spark plug point
Fire, ignition principle are same as Example 1.But Fig. 2 is commonly used.
CIN0- ports are set as A/D conversion inputs, can be exported in measuring circuit and be inserted into simple filter circuit.It is boosting
Tank voltage is continued to monitor after circuit start.Judge whether to arrive voltage up to standard after each conversion end, if not arriving, open again immediately
Turn is changed, to required voltage after stop booster circuit, tank voltage can be controlled to constant pressure value.Or measure boosting by this case method
Rate controls tank voltage to desirable value by rate of pressure rise.
Auxiliary detection circuit, connection AN0 ends, Test Cycle parameter such as coolant water temperature, air-fuel ratio etc. are added, is extended to operating mode
Firing circuit is balanced, referring to subsequent instance.
Example 3:Firing circuit is repaid in oscillating transformers boosting motorcycle constant pressure and cylinder temperature compensation.With reference to figure 4, control circuit is
MC9S08JM60/32 series.Circuit includes each local circuit of the foregoing description of tool corresponding function and connection principle.One is selected
Interrupting input mouth KBIP7, PTB4, PTB5, one AD conversion input terminal ADP2 of two delivery outlets and an analog comparator input
Hold ACMP-.The microcontroller mouth line is resourceful, and each port can need to adjust according to peripheral functionality.Using other single chip circuits, use
The mouth line of identical function replaces.Using oscillating transformers formula booster circuit, output connects accumulator through diode D1.
The PTB5 of control circuit sends out high-level control signal, and the control of booster circuit is reached through driving circuit, that is, resistance
End, vibrates booster circuit, and transformer secondary output induces high pressure, charges through diode D1 to accumulator, energy storage electricity
Pressure gradually rises, until voltage up to standard, through measuring circuit, ACMP- detects signal up to standard.The booster circuit should have sufficiently large
Output power, accumulator is made to obtain voltage up to standard in light-off period.Microcontroller stops rising after signal up to standard is received
The boost conversion of volt circuit stops charging to accumulator, and tank voltage is controlled in the voltage up to standard of design.Microcontroller with
KBIP7 connection ignition signals preferably receive compatible signal up to standard with interrupt mode from ACMP- ends.
The KBIP7 ends connection TTL trigger signals of microcontroller, the signal is from ignition signal trigger device through shaping pulse electricity
The output on road.The input terminal of PTB5 connection driving circuits, the output of driving circuit connect the boosting rectifier control end of booster circuit.PTB5 high

Storage capacitor charging of the circuit i.e. in it.Resistance R1, diode D2 improve driving, make booster circuit output enhancing.It is a kind of optional
Value be;R1 is 200 Ω, and R2 is 5K Ω, is needed adjusted rear determining.
PTB4 connection firing circuits.Simulation compares input terminal ACMP- and connects measuring circuit.Remaining connection and operation principle reference
Each example.Booster circuit only has two kinds of states of start and stop, and adjusts tank voltage with this.Booster circuit can have more multi-form, and match
With corresponding driving circuit.
Sample resistance intrinsic standoff ratio is adjusted, the analogue value output of measuring circuit can also be directly connected to the logic electricity of control circuit
Flat input port such as interrupting input mouth, such as the KBIP6 of this example microcontroller.Using the digital circuit characteristic of microcontroller, with analog signal
Drive digital circuit.This usage, it is sometimes feasible, belong to simple applications.The logic level input port, it is defeated to act as analog comparator
Enter the end i.e. function of signal conversion inputs.
This example increases the auxiliary detection circuit i.e. coolant water temperature temperature measurement circuit from cylinder temperature of ADP2 mouthfuls of connections.Thermometric electricity
Output voltage signal is hindered, represents engine cooling water temperature.Control circuit calculates temperature by measuring voltage, according to temperature value amendment
Required ignition voltage corrects rule and follows the water temperature-tank voltage curve or table etc. obtained by engineering experience.
Meet the corresponding tank voltage of ignition voltage needed for operating mode by two part superpositions, i.e., voltage substantially up to standard and compensation electricity
Pressure.After signal substantially up to standard, increase the operation duration of booster circuit to generate offset voltage.It is basic accumulator should first to be set
Voltage up to standard, value correspond to relatively low ignition energy requirement.Measuring circuit sampling divides when control circuit internal comparator base
The design of quasi- voltage, making accumulator voltage, comparator output variation sends out letter substantially up to standard higher than after voltage substantially up to standard
Number, comparator is caused to interrupt.After voltage substantially up to standard is formed, then generate offset voltage.Its value is calculated according to engineering execution regularity.Work as temperature
When degree detection circuit detects that coolant water temperature is very high, the offset of ignition energy or ignition voltage can reduce, i.e., reaching substantially
Mark signal after, earlier stop booster circuit operation, make tank voltage after signal substantially up to standard it is less rising or no longer on
It rises, vice versa.Control circuit obtains voltage signal substantially up to standard before starting because of compensation, and tank voltage has reached a certain determining value,
Determining compensation rate is then provided according to compensating parameter and compensation model again, this compensation, which has, accurately quantifies meaning.Detection
The auxiliary detection circuit of compensation factor can have a multichannel, and various compensation factors can be with superposition, and detection mode is unlimited.
Substantially voltage swing up to standard is set, it is not necessary to consider cell voltage and rotating speed, but tank voltage climbing speed and battery
Voltage is related, influences to compensate accuracy.Compensation is it is also contemplated that this influence factor.Tank voltage rises to voltage substantially up to standard
The time is needed, in the case where other factors are constant, which is determined by cell voltage.The time is measured, it just can will be electric
Cell voltage compensation factor is added in aforementioned compensation operation, can improve multifactor compensation effect.
By taking coolant water temperature compensates as an example.Into a new period of lighting a fire, start booster circuit and start to accumulator charging simultaneously
Start to measure this up to voltage required time substantially up to standard, until the moment substantially up to standard arrives, basic reaching standard time is measured.
Period measures current temperature value, and carries out following multiple calculating, it is therefore an objective to the time required to generating this compensation.
Using measured temperature and table look-up or with formula calculate Current Temperatures under on the basis of voltage substantially up to standard required benefit
The tank voltage value repaid.Its value is equal to required tank voltage value under the Current Temperatures determined by engineering experience and subtracts electricity substantially up to standard
Pressure value.In multifactor compensation, then superposition other factors influence.
Claim basic reaching standard time and potentiometer substantially up to standard using the last time voltage charging time substantially up to standard of storage
The tank voltage rate of rise is calculated, and this compensation required time is calculated with the tank voltage value of the slope and required compensation.
The end time cumulative calculation after signal substantially up to standard generates this basic reaching standard time, used in the lower period, and
Start meter subtract this compensation time be delayed this compensation required time.
Booster circuit is closed after the completion of delay and waits for time of ignition.Igniting is performed after time of ignition arrival.Terminate this
Light-off period.If consider receive ignition signal and make advance angle processing post-compensation delay remain unfulfilled, only need to igniting when
After being carved into, stop booster circuit, perform igniting.Terminate this light-off period.
Tank voltage is controlled by measuring tank voltage climbing speed, is needed suitable for tank voltage higher or lower than basic
The operating mode balance control of voltage up to standard.It is this because not being that each igniting tank voltage can all undergo voltage substantially up to standard
Control is made of two kinds of methods.
1. calculate tank voltage climbing speed using voltage measurement up to standard(Slope)Method:After period starts, start and rise
Volt circuit after tank voltage to voltage up to standard, measures the time of its experience, calculates rate of pressure rise.
2. utilize the method for known rate of pressure rise control tank voltage:Period accumulates pressure rising time, Test Cycle ginseng
Number, corresponding tank voltage is calculated, then calculate tank voltage according to rate of pressure rise and be raised to work from zero in new duty parameter point
The time required to condition respective value, stop boosting after being reached in the time.
Figure 12 is the schematic diagram of temperature-compensating, and the original of operating mode factor compensation energy storage voltage is explained with the method for simplifying and illustrating
Reason, and further illustrate that the compensation technique is different from the prior art, have and accurately quantify meaning.
Abscissa is the time, and two ordinates represent tank voltage and coolant water temperature respectively.Wherein temperature coordinate rising side
To downward.In figure when water temperature is 100 DEG C, corresponding tank voltage only needs 120v.The rest may be inferred by analogy, wherein less than 0 DEG C corresponding point
Thermoelectricity pressure is 200v or higher.Tank voltage ascending curve, slope K, curvilinear equation v=kt.Numerical value is marked in figure to be served only for
Signal, ascending curve are also reduced to straight line.Practicality should be made to simplify according to actual curve.
Using tank voltage 120V as voltage substantially up to standard.When tank voltage rises to 120v, analog comparator interrupts hair
It is raw.If coolant water temperature side must be 50 DEG C, corresponding ignition voltage for 160v it is still necessary to compensate 40V, curve is extended down to Q points from P points.
From origin to R, point is straight line to curve in figure.Origin need to only be measured to the slope of P points, for calculate tank voltage from the compensation of P points to
The time required to Q points, this figure time value T0=N-M.At the time of wherein N, M rise to 160v and 120v and correspond to for tank voltage.Boosting
Circuit continues to run with the time value, and compensation is completed, and compensation has quantitative performance.Slope K is determined by measuring the rise time, is also disappeared
In addition to device discreteness, the influence factors such as time environment.Than measuring cell voltage compensation slope more accurately and reliably, make ignition energy
It is more accurate quantitatively to be provided by operating mode.
Isobarically Control and tank voltage belong to ignition energy balance control by operating mode factor quantitative compensation, that is, operating mode balance
System.
Tank voltage quantitative compensation technology includes the utilization of engineering experience, but cannot be avoided with the control method need to be by
Engineering is practical to conclude the compensation model obtained.
When tank voltage rises for non-rectilinear, rise rule compensation according to tank voltage after up to standard section, but still be with up to standard
Quantitative compensation based on voltage.And the rate of rise of leading portion is still can refer to, play the advantage of energy balance technology.It can also
A measuring circuit is redesigned, interruption is generated on voltage up to standard or substantially up to standard.By aforementioned principles, it is measured with reaching substantially
The tank voltage attack parameter between voltage interruption is marked, can quantify compensation more accurate.
With influence of the cell voltage balancing battery voltage change to the compensation time is measured, method is still available, method is easy
In understanding, no longer illustrate.
The output of measuring circuit is met into A/D conversion inputs ADP3, is converted using high-speed a/d, after booster circuit startup
Tank voltage is continued to monitor, judges whether to arrive the corresponding energy storage electricity of voltage or duty parameter value up to standard after each conversion end
Pressure, if not arriving, restarting conversion immediately.Under conditions of no working condition measuring is supported, to voltage up to standard after stop booster circuit,
Realize Isobarically Control.Operating mode balance then controls tank voltage to after the corresponding voltage of operating mode, stops booster circuit, waits for igniting
Time of ignition reaches after signal and advance angle processing, implements igniting.
With A/D converted measurement tank voltages, must there are high-speed sampling and conversion, and pass through filtering to make data smoothing.But it measures
It may still be interfered by tank voltage rising.Therefore it can realize that A/D transformation approach measures control tank voltage using the following method.
Period starts booster circuit, stops boosting after certain time such as 2ms, writes down the corresponding time value of boosting.It opens
The tank voltage value of dynamic A/D converted measurements at this time.Tank voltage climbing speed can be calculated.After rate of pressure rise is obtained, profit
Tank voltage is controlled with rate of pressure rise, process is:Start booster circuit, when starting boost gauge, and meanwhile Test Cycle parameter, meter
It calculates corresponding tank voltage and calculates the rise time needed for tank voltage, when if for Isobarically Control with constant pressure value and rate calculations
Between.After pressure rising time reaches, stop booster circuit.

Road, is formed and connection is with reference to Ben Tu and front and rear each example, is repeated no more.Driving circuit is mainly a resistance.Increase battery electricity
Pressure detection may be selected to measure cell voltage auxiliary compensation.
Microcontroller may also directly drive field-effect tube, and the function that can regard driving circuit as is incorporated with control circuit or switch
Circuit, circuit arrangement are still unchanged.
Using single channel start pulse signal, the interval calculation engine speed of nearest two pulses can be used.In this period
Make advance angle processing according to rotating speed after trigger pulse arrival.
The prior art is limitation tank voltage peak, from transformer secondary output tap, through diode, resistance, voltage-stabiliser tube with
Electric resistance partial pressure, the interrupting input of dividing point connection control circuit.When tank voltage rises, voltage-stabiliser tube state change, intrinsic standoff ratio changes,
Control circuit is caused to be interrupted, stops booster circuit.Each parameter is designed, is also used as the measuring circuit of Isobarically Control.The electricity

Etc. can through related circuit connect control circuit.PTB5, PTB4F distinguish contact ignition circuit and driving circuit.ACMP- connects measuring circuit
Simulation output.ADP2, ADP3 connect required duty parameter measuring circuit i.e. coolant water temperature and throttle opening respectively.
Angular signal, position signal include speed of crankshaft and bent axle specific position.The two is generally called ignition signal or may be closed
For all the way.
As Isobarically Control, period, PTB4 exports certain duty cycle signals, and is indicated in the output of measuring circuit
After tank voltage reaches the voltage up to standard of design, control circuit stops booster circuit operation, waits for time of ignition.
Make operating mode balance control, measure each road duty parameter coolant water temperature, throttle opening, control tank voltage is to accordingly
Value waits for time of ignition.
Ignition advance angle is determined by ignition signal and best advance angle amendment.Control circuit is after ignition signal is received, warp
