Can alternatively or extraly include for controlling the method for auxiliary compressor: obtain the specified ladder of boost pressure Degree；Auxiliary compressor-transient state the boost pressure that can be provided by auxiliary compressor is provided based on the specified gradient of boost pressure；And acquisition The change for characterizing auxiliary compressor-transient torque produced by internal combustion engine under described auxiliary compressor-transient state boost pressure Amount.The acquisition of boost pressure-specified gradient such as can be carried out according to driver's wish.To this end, acceleration such as can be detected The movement velocity of the motion of pedal, especially accelerator pedal and can be according to the motion of accelerator pedal, especially accelerator pedal Movement velocity obtain boost pressure-specified gradient.
In addition to basic moment of torsion, auxiliary compressor-transient torque is may be provided for during transient state compensating operation.Wink State compensating operation is compensating operation of short duration, that at most continue several seconds.Can for characterizing the variable of auxiliary compressor-transient torque Be auxiliary compressor-transient torque itself, auxiliary compressor-transient state boost pressure, the rotating speed to be regulated of auxiliary compressor, The transient current of the auxiliary compressor arranged for transient operation or be directly proportional to auxiliary compressor-transient torque its Its variable.
According to the method for controlling auxiliary compressor, when the basic torsion maximum less than or equal to internal combustion engine of internal combustion engine total torque During square, auxiliary compressor-transient torque can be equal to the difference of internal combustion engine total torque with basic moment of torsion.In this case, auxiliary torque May correspond to auxiliary compressor-transient torque.When internal combustion engine total torque basic moment of torsion maximum more than internal combustion engine, auxiliary compression Machine-transient torque can be equal to the difference of maximum basic moment of torsion with basic moment of torsion.In this case, auxiliary torque is equal to or more than auxiliary Compressor-transient torque.
The variable characterizing auxiliary compressor-transient torque can be turned round less than or equal to characterizing maximum auxiliary compressor-transient state The variable of square.The variable characterizing maximum auxiliary compressor-transient torque can be based on for the electric current of auxiliary compressor, internal combustion The real-time rotating speed of machine and/or state parameter as mentioned above determine.Such as, the maximum auxiliary compressor of sign-transient state torsion is being obtained Can be included by transient state duration in the variable of square, during this transient state duration, auxiliary compressor has produced auxiliary Boost pressure.
Such as, the acquired variable for characterizing auxiliary compressor-transient torque can be auxiliary compressor wait adjust The rotating speed of joint.The variable characterizing maximum auxiliary compressor-transient torque can be then maximum auxiliary compressor-transient current, should Maximum auxiliary compressor-transient current is converted into maximum (top) speed, to limit the rotating speed to be regulated of auxiliary compressor.Thus also Can allow such auxiliary compressor transient torque in of short duration compensating operation, its energy expenditure is by maximum auxiliary compression Machine-transient torque is able to optimization.
Such as can determine electric current and based on limit based on the real-time rotating speed of the travel speed level regulated and internal combustion engine The one or more parameters making the real-time status of electrical energy storage device and/or the real-time status of auxiliary compressor determine 0 to 1 In the range of the factor, be then act through this factor will determined by electric current be converted into maximum auxiliary compressor-transient current.Maximum auxiliary Help compressor-transient current additionally can be used to, based on the electric current for auxiliary compressor and utilized by auxiliary compressor Electric current limits the rated speed of auxiliary compressor, thus farthest affects maximum compensation moment of torsion by auxiliary compressor.
Therefore, can so select auxiliary torque, so that it mates basic moment of torsion and nominal torque best.Thus, such as The basic moment of torsion causing high waste gas to discharge can be avoided, and without reducing internal combustion engine total torque.
When driving means includes motor, can also include for controlling the method for auxiliary compressor, determine and treat by motor The motor torque provided, wherein auxiliary torque determines according to motor torque.Auxiliary torque can be mated best subsequently Basic moment of torsion, motor torque and nominal torque.
