Abstract
A suspension control system for controlling a suspension having a shock absorber provided for each wheel of a vehicle includes a damping force change rate detector which detects a damping force change rate indicating a rate of change of a damping force of the shock absorber, and a damping force controller which alters the setting of the damping force on the basis of a relationship between the damping force change rate and an adjustment reference value. The system also includes a road surface condition detector which detects a condition of a road surface on which the vehicle is running on the basis of a change of the damping force of the shock absorber. Further, the system includes a damping force adjustment correcting unit which corrects the adjustment reference value by learning the adjustment reference value on the basis of a parameter related to the damping force of the shock absorber which reflects the condition of the road surface.
