Abstract

A control system for a variable damping force damper, includes: motion state quantity sensors configured to detect motion state quantities of a vehicle; a roll damping force base value setting unit configured to set a roll damping force base value based on the motion state quantities, the roll damping force base value being used to compute a target damping force of the variable damping force damper; a roll rate computation unit configured to compute a sprung mass roll rate and an unsprung mass roll rate of the vehicle based on the motion state quantities; and a roll damping force correction unit configured to correct the roll damping force base value based on a roll rate difference that is a difference between the sprung mass roll rate and the unsprung mass roll rate and to output the corrected roll damping force base value as the target damping force.
