Gear shift operation bag when being raised to the gear of the first gear 7 from the gear of the second gear 8 Include following steps:
After clutch 3 is separated, engine 1 continues to hang over the gear of the second gear 8 and increases torque To provide power needed for driving vehicle, the torque of the first motor 21 and the second motor 22 reduces with reduction of speed, Match when the rotating speed of the first motor 21 and the second motor 22 is reduced to the gear of the first gear 7 Rotating speed when, the first gear 7 is put into gear, the torque of the first motor 21 and the second motor 22 increase with Power needed for driving vehicle is provided, the torque of engine 1 reduces with reduction of speed, and the second gear 8 plucks gear, When the rotating speed of the second transmission input shaft 5 is suitable with the rotating speed of the first transmission input shaft 4, clutch 3 connects Close, engine 1, the first motor 21 and the second motor 22 drive vehicle jointly.
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 Its output torque is slowly adjusted, so as to further improve the combination property of mixed power plant.
