PURPOSE:To always perform optimum posture control of a vehicle by resetting the valve opening time of charge and discharge valves longer or shorter according to the judged result of the present steering direction normal or reverse, and adjusting the charge and discharge quantity of pressure fluid to the cylinder of a suspension. CONSTITUTION:A control device 9 estimates lateral acceleration by a means 18 based on respective detected signals from a vehicle speed sensor 11 and a steering angle sensor 12, and calculates a roll angle by a means 19 based on the lateral acceleration. In this case, a means 20 is additionally provided for setting the charge and discharge time of respective charge and discharge valves 8a - 8d every decided steering angle, based on the target charge and discharge quantity of pressure fluid to the cylinder of a suspension. At this time, the charge and discharge times mean opening times of respective charge and discharge valves 8a - 8d. Further, a means 21 for judging steering direction based on the detected signal from the steering angle sensor 12 is additionally provided. According to the steering direction, normal or reverse, the opening times are respectively reset by a means 22 longer or shorter by a decided time. |
