The invention discloses a vehicle, a control method for active vibration reduction of the vehicle and a vehicle control unit. The method comprises the steps that the rotating speed of a motor is obtained; filtering the rotating speed by using a first low-pass filter and a second low-pass filter to obtain a first filtering rotating speed and a second filtering rotating speed, and obtaining a rotating speed fluctuation value according to the first filtering rotating speed and the second filtering rotating speed; according to the rotating speed, an active vibration reduction adjusting coefficient and an active vibration reduction amplitude limiting torque are obtained; according to the rotating speed fluctuation value, the active vibration reduction adjusting coefficient and the active vibration reduction amplitude limiting torque, the active vibration reduction torque is obtained; and according to the active vibration reduction torque, the motor is controlled through a motor controller. Therefore, the method is wide in applicable working condition, simple to implement and easy to verify, so that the vehicle jitter eliminating cost is lower, and the effect is better.

    本发明公开了一种车辆及其主动减振的控制方法和整车控制器,方法包括:获取电机的转速;分别利用第一低通滤波器和第二低通滤波器对转速进行滤波,得到第一滤波转速和第二滤波转速,并根据第一滤波转速和第二滤波转速得到转速波动值;根据转速得到主动减振调节系数和主动减振限幅扭矩;根据转速波动值、主动减振调节系数和主动减振限幅扭矩,得到主动减振扭矩;根据主动减振扭矩,通过电机控制器对电机进行控制。由此,该方法,适用于工况广且实施简单易验证,使得消除车辆抖动的成本更低、效果更好。
