ABSTRACT:
An apparatus for controlling a damping force of a shock absorber provided between a wheel of a vehicle and a body thereof includes a road surface condition detecting unit for detecting a roughness of a road surface on which the vehicle is traveling, and a damping force characteristic alteration unit for altering the setting of the damping force of the shock absorber on the basis of the roughness of the road surface detected by the road surface condition detecting unit. The apparatus also includes a damping force detecting unit, for detecting a magnitude of the damping force of the shock absorber, and an alteration speed control unit for controlling, on the basis of the magnitude of the damping force detected by the damping force detecting unit, an alteration speed at which the setting of the damping force is altered so that the alteration speed decreases as the magnitude of the damping force increases.
