Background

The automobile kinetic energy recovery device is a device which converts and stores kinetic energy of a vehicle when the vehicle slides or brakes by using an energy storage device (a spring, a battery and the like) and releases the kinetic energy to drive the vehicle to move forwards when the vehicle needs power for driving. During the energy conversion, storage and release processes, the main driving energy of the vehicle, the stored energy and the energy flowing in the reverse direction (from the wheel flow to the storage) during the kinetic energy recovery process are coupled and applied to the driving shaft of the vehicle to drive the vehicle to move forward. Because the magnitude and the flow direction of the energy are constantly changed in the process, the coupling of power transmission is always a great problem in the field of kinetic energy recovery. At present, the multi-power source output power coupling is mostly controlled by an electromagnetic clutch, and the power output by the multi-power source is integrated and output by a planetary gear mechanism coupling mode. The electric control mode has complex structure and relatively poor reliability and response timeliness, and the cross control of a plurality of sets of clutch systems undoubtedly increases the complexity of the system and the manufacturing cost.
