ABSTRACT:
A system for controlling damping force characteristics for respective shock absorbers of a vehicle in which each shock absorber is installed between sprung mass and unsprung mass at each tire wheel position, a front tire wheel side sprung mass vertical velocity and a front tire wheel side relative velocity between the sprung mass and unsprung mass are determined, the damping force characteristics of the shock absorbers located at the front tire wheels side are basically controlled on the basis of the control signal determined on the basis of the front tire wheel side sprung mass vertical velocity, and the damping force characteristics of the shock absorbers located at the rear tire wheels side are, on the other hand, controlled on the basis of the control signal determined on the basis of a front tire wheel side road surface input velocity determined on the basis of the front tire wheel side sprung mass vertical velocity and the front tire wheel side relative velocity determined from a front tire wheel side relative displacement and a rear tire wheel side vertical velocity determined from the rear tire wheel side relative velocity.
