Describe an embodiment of the present invention below in detail.Fig. 2 generally shows the structure of application vehicle of the present invention with the ignition mechanism of internal-combustion engine, the concrete structure of the CDI device of Fig. 3 illustration Fig. 2.
As shown in Figure 2, when the driver starts the main switch 1 of vehicle, the voltage of storage battery 2 just is supplied in CDI device 3, and this CDI device 3 is supplied with igniting (IG) coil 4 in the suitable moment with primary current.Spark coil 4 just drives spark plug 5 after receiving this primary current, pilot engine.Then, corresponding to the rotation of motor, from alternator (ACG) 6 output AC electricity, this Ac is a direct current through rectifier (REG/REC) 7 rectifying conversions.This direct current is supplied in aforementioned CDI device 3 works on it, accumulators 2 chargings simultaneously.8 outputs of pulser coil show the pulse signal of this engine rotation state.In this pulse signal input CDI device 3.In addition, antitheft sniffer 9 is supplied in CDI device 3 with antitheft detected signal.
The following operation that this form of implementation is described with reference to Fig. 4～Fig. 9.Fig. 4 is function description figure, and Fig. 5～Fig. 8 is a data flowchart.Fig. 9 is a routing routing diagram.Represent signal or data with solid line among the figure, be represented by dotted lines the operation or the control signal of carrying out from the outside.
Fig. 4 generally shows the function of this form of implementation, the driver starts main switch 1, ignition system 0 is started working, the pulse signal of ignition system 0 input pulse device coil 8 output and from the antitheft detected signal of antitheft sniffer, in the suitable moment with primary current feed point fire coil 4.Among this external Fig. 4, antitheft sniffer and antitheft detected signal there is no direct relation with the present invention, economize and remove its diagram and explanation.
Fig. 5 is the data flowchart of the ignition system 0 of Fig. 4.Each passes on motor P-and the P+ signal that comes be shaped as rectangular wave in the step 1 of it being carried out waveform shaping.In step 2, obtain the rotation period T of motor according to the interval of this P-signal, and then the inverse of trying to achieve this rotation period T is revolution Ne.Ne delivers to step 3 and step 5 with this revolution.In step 3,, obtain the processing of firing time according to the reset signal of the break-in end of run of revolution Ne, P-signal and step 6 thus.By step 3, firing time and P+ igniting enabling signal are flowed to step 5.In step 5, according to above-mentioned revolution Ne, firing time, P+ igniting enabling signal and P-signal, determine to make primary current to flow through the time of spark coil 4, at this moment between with primary current feed point fire coil 4.
In addition, according to the present invention, give step 6 P-signal conveys in step 1 through waveform shaping.In step 6, carry out the reset processing of break-in end of run signal.Belt type variable-speed motors that adopt in vehicles such as scooter for example more, in this step 6, for example the belt of this belt type variable-speed motor is replaced by new belt after, this moment and above-mentioned P+ signal synchronization are carried out the reset processing of break-in end of run signal.Certainly, the replacing of above-mentioned belt is an example, and the present invention is not limited to belt, but can change other parts, for example motor, from the driving force delivery system to tire etc. the parts of degree of aging maximum wherein.
As modified examples, also can in this step 6, finish the break-in operation forcibly.For example, also can be after above-mentioned part replacement, during to predetermined number, forcing to finish the break-in operation for the P+ signal-count, and step 6 output break-in end of run signal thus.Above-mentioned break-in end of run reset signal or break-in end of run signal then are transported to step 3.
In step 3, as shown in Figure 6, when receiving break-in end of run reset signal, carry out ignition timing according to break-in operation pattern and handle.On the other hand, when receiving break-in end of run signal, then carry out ignition timing and handle according to common operation pattern.Like this, break-in situation according to vehicle component, after having carried out the ignition timing processing of matched internal-combustion engine with it, the low noise of vehicle, rational fuel cost, venting quality or operability etc. can be remained on appropriate state corresponding to the state of its vehicle.
Fig. 6 has illustrated the content of the step 3 of Fig. 5 in further detail.In step 3.1, the conversion control of having carried out the operation pattern according to the reset signal and the P-signal of above-mentioned revolution Ne, break-in end of run.For example carried out the conversion of the operation pattern of the operation pattern of break-in operation usefulness and common operation usefulness.According to the operation pattern that step 3.1 is selected, standard operation/break-in operation enabling signal is exported to step 3.3, and license transfer signal (beginning) is exported to step 3.4, selected operation pattern sequence number is exported to step 3.2.
In step 3.3, the firing time in the calculated signals operation pattern conversion that obtains according to the revolution Ne of motor with by above-mentioned steps 3.1, the step igniting time signal of calculating is exported to step 3.4.And,, calculate the firing time of agreing to this operation pattern sequence number according to the revolution Ne of motor with from the operation pattern sequence number of above-mentioned steps 3.1 in step 3.2, operation pattern igniting time signal is exported to step 3.3 and step 3.4.
Step 3.4 according to the license transfer signal (beginning) of step 3.1, the operation pattern igniting time signal of step 3.2 and the step igniting time signal decision firing time of step 3.3, is exported to abovementioned steps 5 with this igniting time signal.
Illustrate in greater detail the operation pattern conversion control content of abovementioned steps 3.1 now by Fig. 7.At step 3.1.1, the average revolution according to P-signal and engine revolution Ne obtain motor flows to step 3.1.3.At step 3.1.3,, carry out the conversion process of standard operation/low cruise according to conversion process, the revolution Ne of motor and the motor average revolution (average N e) that step 3.1.1 tries to achieve of standard operation/break-in operation.
At step 3.1.2, carry out the judgement of break-in end of run according to the P-signal, break-in end of run signal is exported to step 3.1.3.The decision method of relevant this break-in end of run will be in the back with reference to Fig. 9 explanation.
The details of the operation pattern conversion process of above-mentioned steps 3.1.3 is described below with reference to Fig. 8.At step 3.1.3.1, according to the input of break-in end of run signal, the transfer processing when carrying out the end of break-in running state.To comply with the pattern sequence number that diverts the aim of operation conditions this moment and license transfer signal (beginning) output that the elapsed time is shifted in indication then.
If the operating internal-combustion engine of break-in can not make its inner each parts maintain very high machining accuracy, just have bigger friction so that reduce output, thereby in break-in, will adopt the firing characteristic of paying attention to output trailing wheel.Particularly in the zone that slowly runs of float tolerance internal-combustion engine situation, because with respect to output, the very high tendency of ratio of the output that existence reduces because of friction is so preferably adopt the firing characteristic of the moment of torsion output of paying attention to from the low idle zone to the middling speed pivot region.Belong to known so far knowledge about the concrete property of paying attention to the torque output that the low-medium speed pivot region uses, omit its explanation here.
On the other hand, the output that can obtain being scheduled to owing to reduced friction after break-in finishes, near the output characteristics the attention idle running is unnecessary.So should change the characteristic of paying attention to Economy and paying attention to the high-grade sense into.For this reason, when having improved fuel availability, make the revolution of idle running get predetermined revolution, thereby kept the high-grade sense.In addition, there is no need the machining accuracy of each parts is remained on too high level, so can reduce cost.
In step 3.1.3.2, the processing of the low cruise of transferring to fuel saving expense with the processing among the operation pattern with when breaking away from the low cruise state transitions to common running state.Relevant low cruise takes the known knowledge of genus such as running state characteristic firing time with fuel saving, will not illustrate here.About carrying out the judgement that this class shifts, be judged as in this form of implementation when the state continuation certain hour of difference below predetermined value of engine revolution Ne and motor average revolution (average N e) is above, cruise with certain speed of a motor vehicle.
Referring now to Fig. 9 the object lesson that the break-in end of run is judged among the above-mentioned steps 3.1.4 is described.Fig. 9 shows the bright sequential chart that EEPROM is write, reads in.
Engine revolution when the CPU10 (referring to Fig. 1 and 2) in the aforementioned CDI device connects ignition switch by first, second counter is wherein counted.First counter then makes second counter add 1 and resets described P-signal-count after overflowing.This second counter is added the value set of reading from EEPROM at 1 o'clock in the output according to first counter count value is write among the EEPROM12 when ignition switch is connected.When aforementioned ignition switch disconnected, first counter resetted, and simultaneously the value of second counter was resetted.Like this, second counter adds up the P-signal.
Then, aforesaid CPU10 when the such condition of maximum value of count value * first counter of revolution≤second counter of predetermined break-in end of run is false, promptly has break-in end of run signal=finish; And when above-mentioned condition is set up, break-in end of run signal=end is arranged then.
From the above as can be known, according to this form of implementation, owing to can light a fire under the characteristic firing time of complying with the first operation pattern in service in the break-in of certain parts, and behind this parts break-in end of run, light a fire under the characteristic the firing time of complying with the second operation pattern, so can be fit to the time chien shih internal-combustion engine ignition of this parts current state, thereby might improve for example low noise, fuel cost, discharge characteristic and the operability etc. of vehicle, or the degree of aging of parts is minimized.
In above-mentioned form of implementation, be that the accumulative total of the pulser signal by showing bright engine revolution is differentiated break-in end of run period, or the degree of aging of vehicle component, but the present invention is not limited thereto, and also can count the aggregate-value of vehicle hour, the aggregate-value of vehicle driving distance, the crank revolution (firing pulse device signal) or the igniting operation number of times of motor.
In addition, the present invention also is not limited to the parts lifted in the above-mentioned form of implementation, but can motor and from the driving force delivery system among each parts of tire, the most aging parts are lumped together, decide the firing characteristic of internal-combustion engine promptly to select the operation pattern that is used to light a fire.
Have again, also can be provided with simultaneously being used for differentiating the device that the aforementioned break-in end of run period or the counter aggregate-value of vehicle component degree of aging reset, after being provided with such resetting means, for example when motor or drive component having been carried out maintenance and make it be returned to the state identical with new product, reset by the aggregate-value that makes above-mentioned counter, just the sort of characteristic that can be had when firing time, characteristic turned back to original new product.
