Abstract：In order to improve the effect of the induction motor controller of the electric vehicle and meet the special requirements of the electric vehicle, an improved method—vector control method is put forward. By analyzing the traditional vector control method, a model of induction motor is established considering stator iron loss and rotor iron loss. This model contains physical model and mathematical model. Mathematical model is set up based on the special requirements of electric vehicles on the induction motor, that is, the induction motor must have a wide speed range and fast torque response. Then, through the extraction of the formula, the dynamic compensation proposal and static compensation proposal can be got. Ultimately, the simulation analysis testifies the effectiveness of the method.
