Crawling self-adaptive control method for pure electric vehicle

The invention discloses a crawling self-adaptive control method for a pure electric vehicle. The method comprises the steps: judging whether the vehicle meets a crawling mode entering condition or not; when the vehicle meets the crawling mode entering condition, determining the mode that the vehicle enters the crawling mode; and according to the mode that the vehicle enters the crawling mode and/or the road condition, the motor adjusts the torque of the motor in a torque control mode or a rotating speed control mode. According to the crawling self-adaptive control method for the pure electric vehicle, the motor is controlled to adjust the torque of the motor according to the mode that the vehicle enters the crawling mode and the road condition, no matter which state the vehicle is in, the motor can adjust the output torque in a self-adaptive mode, and it is guaranteed that the vehicle smoothly advances, the motor is controlled to be switched between the torque control mode and the rotating speed control mode,
