Hybrid electric vehicles are driven by two or more energy storages,energy sources and converters,and the core part is the power coupling mechanism,and its performance directly affects the performance of the whole vehicle.This paper mainly summarizes the coupling mechanism of the automotive hybrid system,designs the coupling mechanism of the new CVT hybrid system,and establishes a simulation model in the Matlab/Simulink environment to study the scientific control strategy when switching from pure electric mode to the engine independent drive mode,and verifies the reliability and rationality of the new coupling mechanism,in order to start the engine quickly and smoothly with the help of a reliable and stable coupling mechanism to ensure the effective driving of the car.
