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 coefficient controller which alters the setting of the damping coefficient on the basis of a relationship between the damping force change rate and an adjustment reference value. The system also includes a damping coefficient alteration holding unit which continuously maintains the setting of the damping coefficient at a first level for a holding period after the damping coefficient controller alters the setting of the damping coefficient from a second level to the first level less than the second level, and a road surface condition judgement unit which judges whether or not a road surface on which the vehicle has traveled for the holding period is rough. Further, the system includes a holding period correction unit which elongates the holding period which is to be supplied to the damping coefficient alteration holding unit when the road surface condition judgment unit determines that the road surface is rough.
