For turbosupercharging and engine driven supercharging, when motor is with constant speed drive, valve is opened, and turbine does not work.For the change because of road conditions, ECU is not when changing rotating speed, and in time cut-off valve makes turbine to improve the torsion of motor.In good time for valve comparatively opens or closes according to the numeric ratio of above-mentioned different sensors by ECU, to realize changing between minimum point to peak suction pressure.
For electronic turbine supercharging, when motor is with constant speed drive, valve is opened, and turbine does not work.For the change because of road conditions, ECU is not when changing rotating speed, and in time cut-off valve makes turbine to improve the torsion of motor.In good time for valve comparatively opens or closes according to the numeric ratio of above-mentioned different sensors by ECU, to realize changing between minimum point to peak suction pressure.
Based on engine speed current and before how to determine motor accelerate and how will speed up subsequently for predict in the future or engine booster subsequently require that making it possible to correspondingly to plan supercharging changes.Engine speed increases in time.Time t
1place present engine rotating speed and at time t
0engine speed before place can be used for based on time t
0and t
1between the slope of engine speed graph determine that motor accelerates.T can be predicted based on slope
2place in the future or engine speed subsequently.Then the engine speed of this prediction can be used for planning suction pressure based on the response time of air inlet supply system and regulates.Such as, if the response time of suction pressure supply system is 1 second, so can based on from t
2the acceleration that engine speed is before determined regulates to plan suction pressure to reach time t
2within front 1 second, start.
Accelerate based on motor and regulate the suction pressure being supplied to motor.Whether meet entry condition, such as, entry condition can based on oil temperature, oil pressure, external pressure and/or other engine operating condition multiple.In some instances; such as; motor is from during other situation of to shut down after cold starting or very rapidly do not change in engine idle, traction mode, cruise mode or engine speed; method can exit, because the state quite stable of motor and predictably mode can meet suction pressure needs timely.
Meeting entry condition, method comprises determines that motor accelerates.Such as, method can comprise by sensor and can based on current engine speed (RPM) and one or more before engine speed determination bent axle accelerate.
Method can comprise alternatively determines that whether motor accelerates higher than threshold values.Such as, during the engine operating condition that engine speed does not change rapidly, (such as, when motor accelerates lower than threshold values) can sample engine speed reading via sensor by first rate.But in some instances, during the engine operating condition that engine speed changes rapidly, (such as, when motor accelerates higher than threshold value) increases the sampling rate of engine speed may be favourable.Because determine acceleration based on engine speed reading as described above, the validity that increasing this sampling rate can increase acceleration is predicted makes it possible to plan the suction pressure adjustment in future to meet pressure requirements.
Therefore, if motor accelerates higher than threshold value, method is to increase the sampling rate of engine speed.If accelerated not higher than threshold values or after the sampling rate increasing engine speed.
Method comprises based on acceleration adjustment suction pressure.Such as, the suction pressure of turbine is regulated by modulating valve.This adjustment can further based on current engine speed.Such as, can with one or more before engine speed (such as time t
0place) as one man service time t
1locate current engine speed to determine to carry out based on it acceleration of suction pressure adjustment.
Such as, suction pressure can increase in response to the increase of the engine speed of prediction and reduce in response to the reduction of the engine speed of prediction.As in another example, oil pressure can increase in response to the increase accelerated and reduce in response to the reduction accelerated.In other example other, temporarily can increase suction pressure in response to positive motor acceleration (engine speed such as increased) is current higher than threshold values motor accelerates and reduce subsequently, and only reducing suction pressure accelerating (engine speed such as reduced) current being less than when negative threshold values motor accelerates in response to negative motor.
In addition, suction pressure can be regulated distinctively during different engine operating conditions.Such as, during the first engine operating condition based on acceleration suction pressure can be regulated the first amount and during the second engine operating condition based on acceleration by suction pressure regulate the second amount, even if wherein for the acceleration of phase same level the first amount be also different from the second amount.Such as, accelerate engine charge pressure to be increased by the first amount higher than threshold values in response to motor during the first situation, and can by engine charge pressure increase by second, less amount higher than threshold values in response to motor acceleration during the second situation, the engine load conditions that wherein the second situation representative is less than the first situation.Such as, as other example, during supercharging situation, more radical than during non pressurized situation of the threshold level accelerated in response to positive motor and the increase of engine charge pressure that provides.
In other example other, suction pressure regulates the level and variable cam timing (VCT) operating mode that can accelerate based on motor.Such as, in response to motor accelerate higher than threshold values and the absolute value of VCT error (such as, the difference between the VCT position expected and the VCT position of reality) higher than threshold values, increase suction pressure.
Method comprises the engine running parameter regulating other based on acceleration.Such as, the oil pressure accelerating also to can be used for being designed for other engine subsystems (such as VCT final controlling element) regulates.
