MG1 is generator and the second motor generator MG2 does not work, and the second arrangement of clutch C2 is disconnected and third arrangement of clutch C3 is engaged.
Specifically, due to the second arrangement of clutch C2 disconnection and third arrangement of clutch C3 engagement, since vehicle is in braking
State, thus the first motor generator MG1 is in generating state under the drive of the second driving gear 14, recycles braking energy,
Engine 200 is remain stationary by the frictional force of itself, the second motor generator MG2 idle running.
It is understood that can choose different operating modes according to different situations such as battery capacity, speeds, for example,
When electricity abundance, motor generator can be used and be operated alone, not enough power supply can choose input power point when speed is lower simultaneously
Stream mode operation, not enough power supply is run when speed is higher simultaneously with output power shunt mode, with engine in the case of high speed
Mode operation is operated alone.
For functionally, the power drive system 1000 is by 200, two motor generators of engine, a planet tooth
Mechanism and two arrangement of clutch compositions are taken turns, engine 200 both may be implemented by the control to two arrangement of clutch and individually exported
It is exported with pure electric vehicle, while input power shunt mode and output power point can also be neatly realized under hybrid power operating condition
The mutual switching of stream mode.Pass through the second arrangement of clutch C2 of control, third arrangement of clutch C3, the first motor generator MG1 and the
The different working condition of two motor generator MG2, can be under different operating conditions, to ensure vehicle optimal fuel economy, comfortable
Property or dynamic property demand to the operating mode that selects hybrid power system different.
That is, connecting in 200, two motor generators of engine, a planetary gear mechanism and two arrangement of clutch
On the basis of connecing relationship, pass through the second arrangement of clutch C2, the third arrangement of clutch C3, the first dynamoelectric and power generation with different working condition
