Abstract

A suspension control system for an automotive vehicle is provided. This suspension control system comprises front and rear variable damping force shock absorbers and a control unit which controls the shock absorbers to assume damping force characteristics in a range between preselected higher and lower damping coefficients. The control unit controls the front and rear shock absorbers in a manner wherein the damping force characteristics of the front shock absorber in an extension stroke and of the rear shock absorber in a compression stroke are modified to the higher damping coefficients respectively when vehicle speed is substantially zero.
