ABSTRACT:
A suspension control system for controlling a suspension having a shock absorber provided for a 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 the relationship between the damping force change rate and an adjustment reference value. The system also includes a road surface condition detector which detects, for every first period, the 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, and a damping force adjustment correcting unit which corrects the adjustment reference value by learning, for every second period, 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. Further, the system includes a period adjustment unit which adjusts the first period on the basis of a vehicle speed.
