The invention relates to a pure electric vehicle and an escape control method thereof, and belongs to the technical field of electric vehicle control. According to the method, after the vehicle enters the escape control mode, when an accelerator is stepped down, corresponding torque is output according to the opening degree of an accelerator pedal to drive the vehicle forwards; when the accelerator is released, corresponding torque is output according to the rotating speed of the motor to reversely drive the vehicle; and the torque is dynamically adjusted according to the number of times of trying to escape in the reverse driving process of the vehicle. And when the vehicle is out of trouble, the driver is familiar with the front-back swing amplitude and rhythm process of the vehicle, so that most of the drivers can receive the control method.

    本发明涉及一种纯电动车辆及其脱困控制方法,属于电动车辆控制技术领域。本方法中,进入脱困控制模式后,当油门被踩下则根据油门踏板开度输出对应扭矩向前驱动车辆;当油门被松开则根据电机转速输出对应扭矩反向驱动车辆;在反向驱动车辆过程中根据尝试脱困的次数动态调整扭矩。在车辆进行脱困时,赋予驾驶员熟悉车辆前后悠晃幅度及节奏的过程,有助于大多数驾驶员接受该控制方法。
