A damping control device for an electric vehicle is having a continuously variable transmission between a motor and left and right front wheels. The damping control device drive system includes a feedback control unit, which suppresses a vibration accompanying a disturbance in the rotational speed of the motor, and an operation determination unit, which determines whether or not an absolute value of a second-order differential of the transmission ratio is equal to, or greater than, a predetermined value, wherein when the absolute value of the second-order differential of the transmission ratio is equal to, or greater than, the predetermined value. The feedback control unit performs control of the output torque of the motor whereby a compensation torque component for suppressing a vibration accompanying a gear shift is subtracted from a compensation torque.
