A correction torque command is outputted to a driving/braking torque producing means, in accordance with a correction torque to suppress a vehicle body sprung vibration. When the amplitude of the correction torque is continuing to be greater than or equal to a predetermined amplitude continues for a predetermined time length, a control apparatus outputs a hunting time correction torque command smaller than a normal time correction toque command. Thereafter, when a state of the amplitude of the correction torque being smaller than or equal to the predetermined amplitude continues for a first predetermined time length, the control apparatus returns the output of the correction torque command from the hunting time correction torque command to the normal time correction torque command. Furthermore, the control apparatus continues the output of the hunting time correction torque command if the state in which the amplitude of the correction torque exceeds the predetermined amplitude continues for the predetermined time length, before the expiration of the first time period. The apparatus can restrain the hunting at the time of return to the normal damping control and thereby improve the frequency of carrying out the damping control.
