Abstract
A vehicle suspension system includes a cylinder device provided between a vehicle body member and a vehicle wheel member for the vehicle body member in which suspension characteristics are changed by controlling a hydraulic fluid supply for the cylinder device. A pressure detector detects a hydraulic pressure of the cylinder device for each of the vehicle wheel members, and a warp control unit computes a warping of vehicle body so as to control a hydraulic fluid supply for the cylinder device in a manner such that the warp of the vehicle body is suppressed. The warp control unit is provided with a front pressure ratio computing section for computing a front hydraulic pressure ratio between the cylinder devices for right and left front wheels, and a rear pressure ratio computing section for computing a rear hydraulic pressure ratio between the cylinder devices for right and left rear wheels so that the warp control unit controls the hydraulic fluid supply for the cylinder device based on the front and rear hydraulic pressure ratios. The front pressure ratio computing section produces a value of the hydraulic pressure ratio corresponding to a threshold limit value when the front hydr…
