Abstract
A shock absorber control system having shock absorbers provided respectively between wheels of a vehicle and a body thereof includes road surface condition detecting units provided for the respective shock absorbers, and damping force characteristic alteration units provided for the respective shock absorbers. The shock absorber control system also includes a correction unit for separately generating signals indicative of detection characteristics of the road surface condition detecting units provided for the respective shock absorbers on the basis of road surface condition detection signals generated by the road surface condition detecting units and for separately correcting either reference values used for determining whether or not the road surface is rough by the damping force characteristic alteration units or the road surface condition detection signals on the basis of the detection characteristics of the road surface condition detecting units provided for the respective shock absorbers.
