PURPOSE:To improve the posture stability by linking the control valve of a hydraulic actuator arranged in series to a suspension spring between a suspension arm and a car body to the inclination of the suspension arm, and giving a stroke proportional to the acceleration variation rate for a specific time when the car acceleration exceeds a specific value. CONSTITUTION:A control valve 30 takes in the inclination of a suspension arm 14 (the lower arm) through a link 17, a bell crank 23, and a link 26, and operates linking to the inclination of the suspension arm 14. On the other hand, the detecting acceleration of an acceleration sensor 42 is input to a control device 41 to find the acceleration variation rate. When the turning condition of the vehicle is detected, the control device 41 operates a step motor 44 to move the suspension arm 14 up and down in the feedback direction as the operation amount proportional to the acceleration variation rate for the time determined by the variation rate, prior to the feedback control operation. By such a constitution, the response delay of the feedback control is compensated, and the stability can be improved. |
