Description
The present invention relates to ignition controller for vehicle, in more detail, relate to the vehicle ignition control gear that when the beginning ato unit, the vehicle that avoids theft was carried out judgement.
Applicant was before opened the non-one-tenth units that proposed to be assembled in main switch inside classes such as (for example) reference diode in flat 7-252232 number the spy, when detecting the special utmost point pipe that generates by this nonlinear element, the ignition control device that permission is lighted a fire to motor.
Fig. 3 is the frame assumption diagram of the vehicle ignition control gear before applied for a patent.Main switch 101 is equipped with built-in reference diode 102.The position that main switch (key switch) 101 switches to out by key operation except passed through main switch 101 supply IGNITION CONTROL portions 104 by battery supply 103, also confirms that with normal running voltage VD supplies with ignition control device by reference diode 102 then.If battery supply voltage is VB; The Zener voltage of reference diode 102 (breakdown voltage, reverse drop-out voltage) is VZ; Normal running confirms that voltage VD is (VB-VZ).
Ignition control device 104 detects various voltages such as cell voltage VB and normal running affirmation, if cell voltage VB and normal running are confirmed the difference between the voltage and are in the allowable voltage scope that sets, according to carrying out the ignition timing computing from pulse oscillator 105, generate fire signal S, feed point fire coil 106 is lighted a fire to not shown motor.
Shown in Figure 4 is the operation workflow figure of the vehicle ignition control gear of previous patent of applying for.IGNITION CONTROL portion 104 is structures of utilizing microcomputer system, begins to supply with the running of battery supply.IGNITION CONTROL portion 104 sends the structure that Interrupt Process requires according to the pulse P that the crankshaft rotating angle detector is used to microcomputer.The requirement (S101) that Interrupt Process takes place in IGNITION CONTROL portion 104 detects processing (S102) to the crankshaft rotating angle, turns back to master processor program (S103).
Moreover the angle of rotation and the revolution of solid of rotation detected as the angle information that is provided with unequal interval portion in the reference position of the pulse that provides from the solid of rotation signal generator that is located at crank angle detector etc. according to this reference position.Such electro-detection technology can be understood from fair 7-116983 communique of spy etc.
IGNITION CONTROL portion 104 utilizes various resistor voltage divider circuits that battery supply voltage VB, normal running are confirmed that voltage VD carries out dividing potential drop, and the various voltages of process dividing potential drop gained are transformed into digital voltage data by the A/D transducer, supply to microcomputer.
In main program, cell voltage and normal running are confirmed that voltage VD carries out voltage determination (S104), check whether the potential difference (VB-VD) between cell voltage and the normal operating voltage is in predefined voltage range with interior (S105).If potential difference (VB-VD) is in the predefined voltage range, 104 operations of judging main switch of ignition control device are normal, enter down the step 106, by Interrupt Process, carry out IGNITION CONTROL according to the crankshaft rotating angle timing according to the rules that detects.
When main switch 101 is not when being in normal operating state, the normal operating voltage VD then magnitude of voltage with supply voltage VB is identical.Because potential difference (VB-VD) is zero, IGNITION CONTROL portion 104 judges that main switch 101 is not to be in normal operating state (S105), stops igniting running (S107)
The pulse interval that detects usefulness owing to the crankshaft rotating angle with the proportional relation of engine revolution is short, so processing (S102) is detected at the crankshaft rotating angle and IGNITION CONTROL processing (S106) also must be carried out at a high speed with the short period.Yet, owing to whether be in judgement (the step S104 shown in Figure 4 of normal operating state at main switch 101, S105) to continuously carry out, existing ignition controller for vehicle just detects processing (S102) to the crankshaft rotating angle, and the speed up that IGNITION CONTROL is handled (S106) plays restrictive function.
Not only can not can miss detecting of abnormal operation though continuously whether the operation of main switch 101 is in the judgement that normal state does, can also judge it is not the rotating speed that be in normal running simultaneously reduces motor slowly constantly, the timing of control ignition; One side stops ignition operation progressing under the idling conditions, but adopts the high microprocessor of Processing capacity uneconomical for this reason.
Purpose of the present invention is exactly can not keep within bounds ignition controller for vehicle speed up, that can stop ato unit under the state of upset operation really that IGNITION CONTROL is handled in order to solve such problem, to provide.
For addressing the above problem the vehicle ignition mechanism of doing involved in the present invention, comprise except handover operation that battery supply is supplied with and cut off, normal running affirming signal, the expression handover operation normal main switch of the normal running affirming signal generating means of operation can also take place, and the pulse detection of using according to the angle of rotation that detects bent axle to the angle of rotation of bent axle to the light a fire IGNITION CONTROL portion of driving of motor; It is characterized in that: IGNITION CONTROL portion rises in when having battery supply to supply with, reach predefined timing during, according to the normal running affirming signal, judge the judgement that whether can light a fire.
Owing to during supplying with in the battery supply, reaching predefined timing, judge whether can light a fire, can control igniting with regard to only beginning the rear at ignition operation.After ignition operation begins, owing to the judgement that can not do again whether can light a fire, also just eliminated the processing that whether can light a fire and judge for carrying out, so can realize the IGNITION CONTROL processing in ground, high-speed and high-efficiency ground thereupon.
Moreover, predefined timing, in order will to set regularly according to detecting the pulse of using at the crankshaft rotating angle, so preferably be located at reach detect till the indication of crankshaft rotating angle during.Owing to be before reaching the ignition timing of setting, to judge, pilot engine the startability in the time of also just normal running can not impaired so can stop by abnormal operation for whether lighting a fire.
In addition, judging whether can light a fire according to the normal running affirming signal, is that the occasion that is in the state of normal running judges whether and can light a fire so preferably detect main switch in continuous several times.By such way, for example, just can prevent because of drive starting motor etc. with the situation of supplying with big electric current under because the judgement that the change of battery supply is done to make mistake.

Below with reference to the accompanying drawings example of the present invention is described.Fig. 1 is the frame assumption diagram of vehicle ignition control gear involved in the present invention.Shown in Figure 1 is all-transistor formula (full electronic) ignition control device that the cart of 4 cylinders is housed.Vehicle ignition control gear 1 involved in the present invention is by switching the main switch 3 of the break-make of battery supply 2, the pulsed coil 4 that is used to export the angle of rotation pulse P that detects not shown bent axle axle, 5, the 2 groups of spark coil 6A of ignition control device that utilize microcomputer system to constitute, 6B, 4 spark plugs 7 (#1-#4) by key operation.
(for example) is housed by a circuit, 2 key switch 8 and normal running affirming signal generating means that contact constitutes in the main switch 3.This key switch 8 enters on-state by switching and represents normal running.In this example, be the normal operation signal generating means that adopts reference diode 9 to constitute.Also can adopt a plurality of diode series connection to form the diode level shift circuit, perhaps, for example, adopt varistor, make resistance make nonlinear change, be used for substituting reference diode 9, constitute normal running affirming signal generating means according to service voltage.In addition, can also adopt current regulator diode or current stabilization circuit to constitute the normal operation signal generating means.
Moreover, also can adopt the structure that is intended to cut down the parts number of packages that single-chip microcomputer built-in in the A/D transducer uses.In addition, the water temperature meter drive portion also can comprise mode from driving output to water temperature meter that supply with.
Each drive circuit 17A, 17B comprise the capacitor by battery supply voltage VB charging; The electric charge that will charge in capacitor according to the firing command signal from CPU16 passes through spark coil 6A, the circuit of 6B discharge.By the Secondary coil generation high tension voltage of spark coil 6A, for example, supply with the spark plug of the 1st cylinder and the 3rd cylinder on the one hand.On the other hand, by the 2nd coil generation high tension voltage of spark coil 6B, for example, supply with the spark plug of the 2nd cylinder and the 4th cylinder.
In A/D transducer 14, except each bleeder circuit 12 of process, the battery supply voltage signal of 13 dividing potential drops, normal running is confirmed with beyond the voltage signal, also have from not shown, the water temperature signal of the relevant cooling water water temperature that detects by cooling-water temperature sensor, not shown, various voltage signals inputs such as the throttle valve opening signal of the relevant throttle valve opening that detects by throttle valve opening sensor, the A/D transducer is specified project (the battery supply voltage signal that will carry out conversion through CPU, normal running confirms to use voltage signal, water temperature signal, the throttle valve opening signal), the A/D transducer starts to work, and various voltage signals are transformed into the digital signal input.
The both sides state signal that not shown expression both sides state is in convergence state or is in non-convergence state is fed into the input interface of CPU.Angle of rotation by pulsed coil 4 outputs detects pulse P is fed into CPU16 through 2 system signals of waveform shaping circuit 15 shapings interrupting input end.
Shown in Figure 2 is the operation workflow figure of the ignition controller for vehicle that the present invention relates to of expression.Ignition control device comes into operation after supplying with battery supply voltage VB.CPU16 detects with pulse P according to the crankshaft rotating angle interrupt request (S1) takes place, and the angle of rotation of bent axle is detected processing (S2), returns main program (S3).
In main program, carry out the bent axle angle of rotation according to the detection of crankshaft rotating angle with pulse P under the state of Interrupt Process and detect (the crankshaft rotating angle is detected and is in sync state with pulse P) in the process of handling, battery supply voltage VB and normal running are confirmed also carrying out (S4) with the mensuration of voltage.CPU starting A/D transducer is read in by the normal running affirmation voltage signal of bleeder circuit through dividing potential drop by it, is then read in through the normal running of bleeder circuit dividing potential drop by CPU and confirms voltage signal.The digital data of that CPU16 will read in, as to pass through dividing potential drop battery supply voltage is carried out computing according to the intrinsic standoff ratio of bleeder circuit 12, obtains battery supply voltage VB.Equally, with read in, confirm to carry out computing according to the intrinsic standoff ratio of bleeder circuit 13 through the normal running of dividing potential drop with the digital data of voltage, obtain normal running affirmation voltage VD.
CPU16 counting cell supply voltage VB and normal running are confirmed with the voltage difference (VB-VD) between the voltage VD, judge whether the voltage difference of obtaining (VB-VD) is in the allowable voltage scope with interior (S5).The allowable voltage scope is that the Zener voltage according to reference diode 9 is set under the condition of the standard deviation of considering Zener voltage.When voltage difference (VB-VD) is when being in the allowable voltage scope, CPU16 judges that main switch 3 is the switches that are in normal operating state.Then, in step S6 normal running being detected number of times counts.Be meant that herein normal running detects number of times continuously.Therefore, be judged to be normal running last time but detect number of times zero setting continuously being judged to abnormal normal running again next time.Yet, also can will not be continuous number of times and just be judged to be normal single operation number of times and count.
When voltage difference (VB-VD) was in beyond the allowable voltage scope, CPU16 judged that then main switch 3 is to be in the abnormal operation state, carries out the number of times that detects continuously of upset operation then and count in step S7.Therefore, be judged to be upset operation and when this time being judged to normal running when last time, be with the zero setting of upset operation read-around ratio.Yet, also can will not be continuous number of times and just be judged to be abnormal single operation number of times and count.
In following step S8, detecting before the reference position, crankshaft rotating angle to detect with pulse P by step 4 to step 7 processing (judging the whether processing of normal running of main switch 3) and carrying out the synchronous circulation processing with the crankshaft rotating angle.So, finish in the initial stage processing finishes by the power supply input at CPU16, just battery supply voltage VB and normal running are confirmed that doing the 1st time with voltage VD measures and judge for the 1st time, detects the circular treatment that goes on foot S4 ￣ B step S7 with pulse P synchronously with the crankshaft rotating angle then.
When detecting reference position, crankshaft rotating angle, CPU16 enters the step 9, judges that normal running detects number of times continuously whether more than predefined specified value.Judge then that as detecting continuously more than the specified value of number of times in normal running main switch 3 is in normal operating state this moment; Move on to step S11 and carry out IGNITION CONTROL; Do not reach specified value if normal running detects number of times continuously, judge that then main switch 3 is in the upset operation state, stop to handle (S10).Yet, main switch 3 is judged to the normal running that is in normal operating state detects number of times continuously and also can change by being located at judgement number of times configuration switch in the IGNITION CONTROL portion 5 etc.
In addition, to not continuous number of times and just be judged to be normal single operation number of times or will be judged to be under the situation that abnormal single operation number of times counts when being in, also can be in the moment that detects reference position, crankshaft rotating angle, from various number of times, get majority as foundation, carry out normal running or the also final judgement of upset operation.
Because whether detect what carry out synchronously with pulse P with the crankshaft rotating angle is that the processing that is in normal operating state is the structure that a kind of circulation is carried out for main switch 3, can not handle with timer, can adopt with the corresponding time lag of the rotational speed of bent axle and repeatedly judge.Therefore, because the benchmark of setting as ignition timing with reference position, crankshaft rotating angle just can carry out IGNITION CONTROL, constitute according to the result who repeatedly judges as the final judgement of whether permitting the igniting action, just can prevent, for example, because the erroneous judgement of reasons such as the cell voltage change generation that causes because of the big electric current of supplies such as starting motor (starting use motor), thereby can accurately detect whether normal running of main switch 3.In addition and since be the benchmark of setting as ignition timing with reference position, crankshaft rotating angle just can carry out IGNITION CONTROL during permit the judgement of igniting, so when main switch 3 normal runnings, can not impair the startability of motor.
The crankshaft rotating angle that the CPU16 basis detects in crankshaft rotating angular detection treatment S 2 in the IGNITION CONTROL of step S11 is handled is carried out computing to the ignition timing of each cylinder, ignition timing output firing command according to the rules, drive circuit 17A, 17B is by spark coil 6A, 6B is to each ignition spark plug 7 (#1, #3), (#2 #4) supplies with the high tension voltage igniting.
After the final judgement that goes on foot S9 igniting permission, Interrupt Process is carried out in circulation and IGNITION CONTROL is handled.Owing to unnecessaryly proceed existing such processing, be in the IGNITION CONTROL that can have no to go on foot S11 under the situation of high speed rotating at motor with hindering and handle from step S4-step S7.
CPU16 carries out the computing of engine revolution according to the cycle that detects reference position, crankshaft rotating angle, with operation result by revolution counter drive portion 18 as the revolution counter of in the output supply figure of revolution counter, not drawing.
Vehicle ignition control gear involved in the present invention by above explanation, owing to be a kind ofly to rise, carry out the structure of the judgement that could light a fire till the predefined timing according to the normal running affirming signal, so can after the igniting action begins, carry out the judgement that to light a fire in the moment from battery supply voltage VB to IGNITION CONTROL portion that supply with.Owing to be after igniting action beginning, to carry out the judgement that could light a fire, thus can eliminate the thing followed to this igniting do could judgment processing keep within bounds, can carry out the IGNITION CONTROL processing of high-speed and high-efficiency.
Moreover, since detect according to the crankshaft rotating angle that setting with pulse P lights a fire and be timed to detect reference position, crankshaft rotating angle till during carry out the judgement that could light a fire, pilot engine by upset operation so stop under the condition of startability that can be in the time can not impairing normal running.
In addition, because being the occasion of the repeatedly continuous detecting the normal running of main switch 3 done according to the normal running affirming signal, the judgement that could light a fire carries out ignitable judgement, so can prevent, for example, the erroneous judgement of when supplying with the change of the battery supply voltage that big electric current produces thereupon because of drive motor, being done.
