Plate is released, and any power source in drive system does not provide power needed for vehicle traveling；2) vehicle is in damped condition.
When vehicle is in coasting mode (vehicle can travel, referred to as car slipping) and damped condition, wheel can be in power train
Effect is lower to drive transmission output shaft 3 to rotate, and the output shaft 3 of rotation can be generated electricity with driving motor EM, be charged for battery, realize energy
Amount recycling.
Under energy recuperation mode, clutch K0 is in discrete state, and motor EM works in the generator mode, internal combustion engine
ICE does not work；Synchronizer A, synchronizer C are in not engagement state, synchronizer B and are engaged with gear Z31, transmission output shaft 3
Torque is transmitted to the rotor hub of motor EM via gear mesh Z31-Z11 and the first input shaft 1, and motor EM is thus made to generate electricity.
