Abstract
A cylinder unit for adjusting a vehicle height of the vehicle body is interposed separately or independently between the vehicle body and each wheel. The supply and discharge of the operating fluid to and from each of the cylinder units is performed by generating a control signal indicative of the quantity of supplying and discharging the operating fluid to and from the flow rate adjusting valves. The control signal is determined so as to allow an actual angle of a roll of the vehicle body to agree with a target angle of the roll thereof. When the automotive vehicle is cornering, particularly rapidly, the control signal is corrected in such a manner that the larger the inner pressure of the cylinder unit, the smaller the quantity of the operating fluid to be supplied or to be discharged. Specifically, the correction is made so as to minimize the quantity of the operating fluid to be supplied to or to be discharged from the cylinder unit on the outer wheel side upon cornering, which has a higher inner pressure, and to maximize the quantity of the operating fluid to be supplied to or to be discharged from the cylinder unit on the inner wheel side upon cornering, which has a lower inn…
