The invention provides an electric vehicle shaking suppression method, an electric vehicle and a readable medium. The method comprises the steps that S11, whether anti-shake enabling of a vehicle control unit is started or not is judged, and if yes, the step S12 is executed; s12, the motor controller counts the number of times that the change rate of the rotating speed of the motor exceeds a first threshold value, whether the number of times is larger than a second threshold value or not is judged, if yes, the step S13 is executed, and if not, the step S14 is executed; step S13, the motor controller closes an anti-shake function; and S14, starting an anti-shake function by the motor controller, and outputting a corresponding anti-shake torque according to the change rate of the rotating speed of the motor. According to the method, after the anti-shake enabling of the vehicle control unit is started, the anti-shake function is automatically judged to be started or stopped through the motor controller, the shaking problem in the driving process under the limiting working conditions such as slippery roads or vehicle instability can be well solved, and the method is wider in application range.

    本发明提供了一种电动汽车抖动的抑制方法、电动汽车及可读介质。其中方法包括步骤S11:判断整车控制器的防抖使能是否开启,如果是,则进入步骤S12;步骤S12:电机控制器统计电机转速变化率超过第一阈值的次数,判断所述次数是否大于第二阈值,如果是,则进入步骤S13,如果否,则进入步骤S14;步骤S13:所述电机控制器关闭防抖功能;步骤S14:所述电机控制器开启防抖功能,根据所述电机转速变化率输出相应的防抖转矩。本发明在整车控制器的防抖使能开启后,通过电机控制器自主判断开启或关闭防抖功能,能够很好的解决湿滑路面打滑或车辆失稳等极限工况行驶过程中的抖动问题,方法适用范围更广。
