From the point of view of above-mentioned gear shift operation process, an engine can provide drive temporarily in shift process
Whole power needed for motor-car, therefore the adjustment of rotational speed of another engine is not made excessive demands when very short
It is interior to complete.Conventional shift process about 1s is even shorter, i.e. the adjustment of rotational speed requirement for engine
Rapidly.And embodiments of the invention do not make excessive demands completion in this time index, 2~4s, no doubt
Adjustment time is shorter preferably, but slightly longer also have no very influences.
If engine 1 is gasoline engine, the torque of engine 1 reduces by reducing entering for engine 1
Tolerance is carried out；The torque increase of engine 1 is carried out by increasing the air inflow of engine 1.Many institutes
Known, the response speed that motor torque is adjusted by adjusting throttle opening is slower, generally not
It is recommended that using, but motor torque is reduced using the method at late ignition moment more.But in this reality
Apply in example, the shortcoming for adjusting the method for throttle opening is not obvious, can use completely.Certainly,
It is also possible to carry out motor torque regulation to coordinate other method simultaneously, is not limited thereto system.
If engine 1 is diesel engine, the torque of engine 1 reduces the combustion by reducing engine 1
Oil spurts amount is carried out；The torque increase of engine 1 is entered by increasing the fuel injection amount of engine 1
OK.
Because the response speed and precision of motor are all very high, the first motor 21 and the second motor 22
Torque reduces by reducing the driving current of the first motor 21 and the second motor 22 to carry out；First motor
21 and second motor 22 torque increase by increasing the driving electricity of the first motor 21 and the second motor 22
Stream is carried out.
As described above, the rotational speed regulation of the motor 21 of engine 1 or first and the second motor 22 in gearshift
It is not required for completing within the extremely short time, therefore can also relatively delays on the premise of other performances are ensured
