Multimode drive control method for pure electric vehicle

The invention provides a multimode drive control method for a pure electric vehicle. The method comprises the steps that an overall vehicle controller judges the state of a driving mode of the vehicle, a torque parameter value is obtained by searching a function table through an input value in accordance with that different driving modes correspond to different function tables and input values of the function tables are current vehicle speed and openness of an accelerator pedal, and finally, a torque output value is determined by a product of the obtained torque parameter value and a peak torque value, which can be reached at a current revolving speed, of a motor. According to the method, through introducing a camber control strategy formulated through vehicle speed signals in various modes, the disadvantages resulting from the deficiency of torque of a rear segment of the driving motor are effectively avoided, the working interval of the driving motor is optimized, and the economical efficiency of the whole vehicle is increased.
