Electricity condition, a part of power that engine is transmitted to power output shaft drive the second motor EM2 power generation, and electric energy storage is onboard moved
In power battery, remaining engine power, which is fixed on power output shaft, selects high tap position or low grade by system torque demand
Position passes to differential mechanism by power output jackshaft, the main driving gear that subtracts, and driving vehicle advances；When Brake energy recovery, the
Two motor EM2 are generating state, and from wheel to the second motor EM2 reverse drive, electric energy is stored in power battery power；
Preferably, under the mixed connection operational mode of engine and two motor forms, first clutch in conjunction with second clutch,
First motor EM1 and the second motor EM2 are in operating status, when vehicle needs maximum power, engine and first motor EM1
It contributes together with the second motor EM2, meets vehicle significant power demand；When also needing low-speed big, synchronizer is located at right position,
It is linked into low grade, when needing high-speed high-power, synchronizer is located at left position, is linked into top grade；When power battery electricity is inadequate on vehicle, first
Motor EM1 is changed into generating state, and the second motor EM2 can be supplied to drive vehicle, Huo Zheduo together with engine by generating electricity
Remaining electric energy storage is onboard in power battery；Second motor EM2 can also be according to circumstances in electronic, idle running or generating state；
When Brake energy recovery, first motor EM1 and the second motor EM2 are generating state, and power is from wheel to first motor EM1 and the
Two motor EM2 reverse drives, electric energy are stored in power battery；When Brake energy recovery, first motor EM1 and the second motor
EM2 is generating state, and for power from wheel to first motor EM1 and the second motor EM2 reverse drive, electric energy is stored in power battery
It is interior.
