Abstract
A suspension control system for a vehicle includes a plurality of hydraulic cylinders interposed between the vehicle body and the respective axles of front right, front left, rear right and rear left wheels for controlling the vehicle height by the action of a hydraulic fluid charged into and discharged from the cylinders. A plurality of normally-closed charge-discharge valves are provided to correspond to respective of the hydraulic cylinders. When the hydraulic fluid is to be charged into or discharged from the hydraulic cylinders, among the charge-discharge valves, at least the left and right charge-discharge valves associated with either the front right and front left wheels or the rear right and rear left wheels are not opened simultaneously, but either of the left and right charge-discharge valves is selectively opened.
