PURPOSE:To simplify constitution and improve versatility by alternately connecting upper and lower oil chambers, of a right and left pair of hydraulic cylinders provided at the front and rear of a vehicle, with a pair of oil paths connecting a hydraulic unit and a sub-accumulator via a control valve in a vehicle attitude control device. CONSTITUTION:Since a detected signal is not inputted from a lateral acceleration sensor 40 at the time of straight going, a hydraulic variation not arises in each hydraulic cylinder 1, and the compression of the cylinder 1 is compensated with a sub-accumulator 10. A control valve 2 is controlled with the tensile strength and compressive force of each right and left cylinder 1 necessary to prevent the roll of a vehicle operated with a controller 4 by the detected signal of the sensor 40 at the time of the turning. This causes the pressure oil accumulated in a main-accumulator 32 to be supplied to the cylinder 1 via a supply valve 30, control valve 2, and selector valve 20, and the roll is prevented. This constitution enables a constitution to be simplified and vertically improved. |
