Abstract
A suspension system for a vehicle has cylinder devices, in which suspension characteristics are changed by controlling fluid supply or discharge to or from the cylinder devices. In the suspension system, after sensing a vehicle height displacement, the fluid supply or discharge to or from the cylinder devices is controlled so as to set the vehicle height displacement to a desired value in a vehicle height displacement control. Also, the fluid pressure in the cylinder, devices is sensed, and a warping of the vehicle body is computed, based on sensed pressures. Then, fluid supply or discharge to or from the cylinder devices is controlled so as to suppress the warping of the vehicle body in a warp control. According to predetermined conditions, a warp gain coefficient in a warp control unit is changed, so that the vehicle height displacement control and the warp control are performed optimally.
