Abstract
A vehicle suspension system of the disclosure is provided with a cylinder device between a vehicle body member and a vehicle wheel member for the vehicle body member by which suspension characteristics are changed. The suspension characteristics are changed by controlling hydraulic fluid supply for the cylinder device, a vehicle height detecting device for detecting a vehicle height displacement, a vehicle height change rate detecting device for detecting a change rate of the vehicle height displacement, and a control device for receiving signals from both the vehicle height displacement detecting device and the vehicle height change rate detecting device to control the hydraulic fluid supply for the cylinder device. This hydraulic fluid supply is controlled in accordance with a vehicle height change rate gain in a manner that the change rate of the vehicle height displacement is suppressed a gain change device is also provided for changing the vehicle height change rate gain in accordance with a predetermined condition so as to change the control of the hydraulic fluid for the cylinder device. A desirable vehicle height displacement control can therefore, be accomplished.
