A vehicle includes a motor and a motor controller. A damping control method for the vehicle includes: obtaining a rotation speed of the motor; filtering the rotation speed through a first low-pass filter to obtain a first filtered rotation speed, filtering the rotation speed through a second low-pass filter to obtain a second filtered rotation speed, and obtaining, by a vehicle controller, a rotation speed fluctuation value based on the first filtered rotation speed and the second filtered rotation speed; obtaining, by the vehicle controller, an active damping adjustment coefficient and an active damping clipped torque based on the rotation speed; obtaining, by the vehicle controller, an active damping torque based on the rotation speed fluctuation value, the active damping adjustment coefficient, and the active damping clipped torque; and controlling, by the motor controller, the motor based on the active damping torque.
