Embodiment
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Being exemplary below by the embodiment be described with reference to the drawings, only for explaining the present invention, and can not limitation of the present invention being interpreted as.
Below in conjunction with accompanying drawing, controlling method, system and the vehicle according to the motor of the embodiment of the present invention is described.
Fig. 1 is the flow chart of the controlling method of motor according to an embodiment of the invention.As shown in Figure 1, and composition graphs 2, the according to an embodiment of the invention controlling method of motor, comprise the following steps:
Step S101: the vibration signal detecting predetermined crank angle scope intrinsic motivation.Such as: can by the scope of crankshaft position sensor and detonation sensor monitoring engine compresses atdc 0-30 DEG C of A (i.e. 0-30 ° of crank shaft angle) or the vibration signal of a certain section of crank angle range interior (i.e. predetermined crank angle scope)
Step S102: judge whether super detonation occurs according to the vibration signal within the scope of predetermined crank angle.
Specifically, comprising:
S1021: filtering is carried out to vibration signal.
S1022: filtered vibration signal is carried out integral and calculating to obtain integral value.
S1023: judge whether integral value is greater than predetermined threshold value.
S1024: if then judge super detonation occurs.
That is, carry out integral and calculating by after the vibration signal filtering of collecting within the scope of above-mentioned predetermined crank angle, and the vibration signal exceeding predetermined threshold value is identified as pre-ignition, wherein, predetermined threshold value can rule of thumb be determined.
Step S103: if (if namely super detonation occurring), then adjust fuel injection pulsewidth and reduce combustion temperature.Particularly, by adjustment fuel injection pulsewidth, air fuel ratio is maintained in prespecified range, thus the combustion temperature in the cylinder of motor, prespecified range is such as the scope of [0.7,0.9].In this example, by controlling oil sprayer adjustment fuel injection pulsewidth.
As a concrete example, when recognizing super detonation and occurring, controlling oil sprayer increases fuel injection pulsewidth, by a certain fixed value of the air-fuel ration control in cylinder within the scope of 0.7-0.9, reduces cylinder temperature and then reduction or eliminates the generation of super detonation.This action maintains Preset Time, such as 10 seconds to 20 seconds.
Step S104: judge in the Preset Time after adjustment fuel injection pulsewidth, whether (as 10 seconds to 20 seconds) again super detonation occur.If namely pre-ignition in Preset Time (i.e. super detonation) phenomenon does not occur again, then recover normal state.
Step S105: if again there is super detonation in the Preset Time after adjustment fuel injection pulsewidth, then by reducing combustion temperature, reducing maximum load and/or interrupting fuel feeding to avoid the generation of super detonation.Such as: according to super detonation number of times, inlet and exhaust valve overlapping angle, air inflow, fuel injection quantity and motor start and stop are controlled, thus the effect reducing combustion temperature, reduce maximum load and/or interruption fuel feeding can be reached, and then avoid the generation of super detonation.That is, judge to occur that super detonation is as occurring super detonation first using above-mentioned steps S102, if then repeatedly there is super detonation within the scheduled time afterwards, then pass through to reduce combustion temperature, reduce maximum load and/or interrupt fuel feeding according to the number of times of super detonation, namely inlet and exhaust valve overlapping angle, air inflow, fuel injection quantity etc. are controlled accordingly, thus eliminate super detonation.
Specifically, shown in composition graphs 2, according to super detonation number of times by reducing combustion temperature, reducing maximum load and/or interrupting fuel feeding to eliminate or to reduce super detonation, comprise further:
If 1 number of times (i.e. super detonation number of times) is less than first threshold, then reduce inlet and exhaust valve overlapping angle to reduce combustion temperature.Such as: when 100 burn cycle after super detonation generation first or generation the 2nd pre-ignition in 5 seconds, then reduce inlet and exhaust valve overlapping angle by controlling intake and exhaust VVT phase discriminator, thus increase internal waste gas amount, reduce combustion temperature, and maintain the scheduled time (as 10 seconds to 20 seconds), if super detonation is eliminated, then recover normal state.
If 2 super detonation number of times are greater than first threshold and are less than Second Threshold, then reduce air inflow to reduce described maximum load.Such as: when 100 burn cycle after super detonation generation first or when there is 3 pre-ignition in 5 seconds, then control pressurized machine exhaust gas bypass valve opening by turbocharger controller and reduce air inflow, this operating mode maximum load is made to reduce by 40%, and maintain the scheduled time (as 10 seconds to 20 seconds), if super detonation is eliminated, then recover normal state.
If 3 super detonation number of times are greater than Second Threshold and be less than the 3rd threshold value, then interrupt fuel feeding, and control engine restarting.Such as: when 100 burn cycle or generation 5 pre-ignition in 5 seconds after super detonation generation first, control oil sprayer and interrupt oil spout, and make gas pedal reset to 0, then control point fire coil restarts motor, thus avoids super detonation to damage motor.
If 4 super detonation number of times are greater than the 3rd threshold value and be less than the 4th threshold value, then engine load is limited until ato unit next time.Such as: when when super detonation rear 100 burn cycle occurs or 20 pre-ignition occurred in 5 seconds first, within limiting engine load to 60% of this operating mode maximum load, wait for that next time recovers the normal state of motor after manually restarting motor, thus avoid super detonation to damage motor.
In the examples described above, first threshold increases successively to the 4th threshold value.First threshold is such as 3, Second Threshold be such as the 4, the 3rd threshold value be such as the 10, the 4th threshold value is such as 25.
According to the controlling method of the motor of the embodiment of the present invention, according to crank angle range determination super detonation region, and determine whether super detonation occurs according to the vibration signal of motor in this region, when there is super detonation, combustion temperature can be reduced by adjustment fuel injection pulsewidth, thus eliminate or reduce the generation of super detonation, avoid damaging motor.And; the severe degree of burning can be reflected according to super detonation number of times; for the severe degree of different burnings by reducing combustion temperature, reducing maximum load and/or interrupt controlling motor for wet goods many aspects; avoid further or eliminate super detonation; available protecting motor; improve the life-span of motor, lifting vehicle safety.
