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.

Abstract: A suspension control system for controlling a suspension having a shock absorber provided for a wheel of a vehicle includes a damping force detector which generates a damping force detection signal which indicates a change of a damping force of the shock absorber based on a condition of a road surface on which the vehicle is running. The system also includes a sprung resonance component extraction unit which extracts a sprung resonance component signal from the damping force detection signal. The sprung resonance component signal includes components having frequencies around a sprung resonance frequency of the shock absorber. Further, the system includes a determining part which determines whether or not the sprung resonance component signal exceeds a first level range provided for detecting a sign of the occurrence of a long-term vehicle vibration and which outputs a determination result. Moreover, the system includes a damping force controller which controls the shock absorber so that when the determining part determines that the sprung resonance component signal exceeds the first level range, the damping force of the shock absorber is altered to and maintained at an increased level and thus the suspension is maintained at a state which corresponds to the increased level and which is harder than before.
