摘 要：
A simplified vehicle model with 5 freedom is designed.Then the working principle of DTC(Direct Torque Control) is introduced,at the same time,the working law of DTC flux have been analyzed in this paper.Because the DTC flux have strongly nonlinear features,a decoupling which divides the flux into two parts is proposed in this essay.Then shear force is calculated separately,and combined with the vibration characteristic of EV,the total force is converted into vertical direction.At last,the model of EV and motor vibration system is built in the Matlab,and several simulation results are analyzed.
