Vibration damping control device for vehicle
A vibration damping control device that controls driving power of a vehicle to suppress pitch vibration or bounce vibration includes: a vibration damping control unit that controls a driving torque of an engine so as to suppress the amplitude of the pitch vibration or bounce vibration on the basis of a wheel torque generated at a contact portion between a wheel of the vehicle and a road surface; and a compensating component regulating unit that varies the magnitude of a compensating component, which is calculated by a vibration damping control unit and which compensates the wheel torque for vibration damping control, on the basis of a change of characteristic, such as a wear state quantity of a movable portion of a throttle valve of the engine.
