Abstract
The suspension system has a cylinder unit disposed at each wheel for displacing a vehicle height of the vehicle body by a supply or a discharge of operating liquid and a vehicle height sensor disposed at each wheel for sensing the vehicle height of the body. An actual status amount of the posture of the body, such as a pitch amount or a roll amount, is determined on the basis of output from the vehicle height sensor, thereby controlling the supply or discharge of the operating liquid to or from the cylinder unit in order to allow the actual posture amount to reach a given target value. When the running status is detected to such an extent that changes the status amount, the target value can be corrected in anticipation prior to a change in the posture status amount, thereby preventing the change in the posture status amount. The running state includes, for example, when the range position of the automatic transmission is shifted from the range P or N to the running range, when the brake for braking the brake is operated, and when the steering wheel is rapidly steered.
