Vibration damping control device for vehicle

摘要

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.

1. A vibration damping control device for a vehicle, which executes vibration damping control in which driving power of the vehicle is controlled to suppress pitch vibration or bounce vibration of the vehicle, the vibration damping control device comprising:
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 that is generated at a contact portion between a wheel of the vehicle and a road surface and that acts on the wheel, and that calculates a compensating component for compensating the wheel torque for the vibration damping control; and a compensating component regulating unit that varies the magnitude of the compensating component on the basis of a wear state quantity of a movable portion of a throttle valve of the engine.
