Abstract: An active roll control and leveling system operating between the sprung and unsprung masses of a vehicle or the like includes a plurality of shock absorbers attached between the sprung mass and the unsprung mass, a hydraulic source for supplying fluid at two hydraulic pressures, a sensor for detecting the vehicle's inertial change induced when the vehicle is turning, and a control unit for actively introducing fluid at hydraulic pressure to each shock absorber. The active roll control and leveling system includes a pump with a reservoir and a high pressure accumulator for delivering two separate hydraulic pressures. The active roll control and leveling system also includes an accumulator for each shock absorber and a controlling plunger for directing the pressures simultaneously to the shock absorbers.
