Based on the basic analysis of the structure and power elements of the hybrid vehicle, this thesis presents a powertrain system with a metal pushing belt cvt, aiming to the development status and trend of the hybrid vehicle technology in our country. a rational control strategy and its work mode of this powertrain system are determined, and correlative parameters such as the engine power, the starting torque, and the differential ratio, the rated power and torque of the motor, and the ratio of the torque synthesizer are systematically designed for the changan star 6350b. at the same time, the design of these parameters is considered as the base of the simulation of the motor control system in next step
