This paper first introduces the structure and principle of the electric vehicle( EV) power train and constructs a mathematic model. Then the parameters of the assembly components in the electric power train system are determined according to the design requirements. Meanwhile,the vehicle control strategy and the motor controller are designed based on the direct torque control method of sliding mode control to improve the vehicle efficiency and performance. The simulation results show that the simulation model for power train is accurate in control performance,which can lay the foundation for the study on electric vehicle.
