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.
