PURPOSE:To properly suppress the rolling of a car body by setting the steering angle at which the ground clearance adjustment is necessary on the basis of the car speed and feeding and discharging an aimed quantity of supplied and discharged oil which is estimated at each set steering angle and eliminating the useless operation in feeding and discharging oil. CONSTITUTION:In a controller 11 which receives each detection signal supplied from a number of ground clearance sensors 10a-10d, steering angle sensor 12, and a car speed sensor 13, a means 14 sets the unit steering angle at which the ground clearance adjustment at a prescribed car speed is necessary. Further, a means 15 estimates the lateral acceleration speed generated on a car body at each steering angle. Further, a means 16 calculates the change of the roll angle generated by the lateral acceleration speed and the change of the length of a hydraulic cylinder installed on each wheel. A means 17 sets an aimed oil feed/discharge quantity supplied or discharged from the hydraulic cylinder according to the variation of the length of the hydraulic cylinder. Then, each time when the aimed steering angle and the detected steering angle accord, a CPU 18 controls each oil feed/discharge means 7a-7d on the basis of the aimed oil feed/discharge quantity. |
