A vehicle and an active damping control method therefor, and a vehicle controller are provided. The method includes the following steps. A rotation speed of a motor is obtained. Filtering is respectively performed on the rotation speed through a first low-pass filter and a second low-pass filter, to obtain a first filtered rotation speed and a second filtered rotation speed, and a rotation speed fluctuation value is obtained based on the first filtered rotation speed and the second filtered rotation speed. An active damping adjustment coefficient and an active damping clipped torque are obtained based on the rotation speed. An active damping torque is obtained based on the rotation speed fluctuation value, the active damping adjustment coefficient, and the active damping clipped torque. The motor is controlled through the motor controller based on the active damping torque. The method is applicable to a wide range of working conditions, is easy to implement and verify, and can effectively eliminate vehicle vibration at lower costs.
