The invention discloses a control mode conversion method for a driving motor of an electric automobile. The method comprises the following steps: switching A from reset to PWM closing; switching B between a PWM closing mode and a zero torque mode; switching C between a zero torque mode and a forward driving mode; switching D between a zero torque mode and a reverse driving mode; switching E between a zero torque mode and a regenerative braking mode; switching F between a zero torque mode and a speed mode, switching G between a motor controller into or out of a fault mode, switching H between afault mode into PWM (Pulse-Width Modulation) closing, switching I between a motor controller into a dormant state, switching J between a driving or braking state into a PWM off state, and switching Kprohibiting mode switching. By the adoption of the technical scheme, mode switching of the driving motor controller of the new energy electric vehicle is achieved, control processing of the new energy electric vehicle is finer and smoother, and the running stability, riding comfort and control stability of the vehicle are improved.

    本发明公开了一种电动汽车驱动电机控制模式转换方法,包括:从复位到PWM关闭的转换A、PWM关闭与零转矩模式的转换B、零转矩模式与正向驱动模式的转换C、零转矩模式与反向驱动模式的转换D、零转矩模式与再生制动模式的转换E、零转矩模式与速度模式的转换F、电机控制器进入或退出故障模式的转换G、故障模式进入PWM关闭的转换H、电机控制器进入休眠状态的转换I、驱动或制动状态进入PWM关闭状态的转换J、禁止模式切换的转换K。采用上述技术方案,实现对新能源电动汽车驱动电机控制器模式切换,使得新能源电动车控制处理更加细腻平顺,提高车辆行驶的平稳性、乘坐的舒适性和操控的稳定性。
