28 ABSTRACT OF THE DISCLOSURE A digital suspension system for a wheeled vehicle incorporates digital hydraulic actuators at each wheel and includes a system for sensing lateral and longitudinal accelerations of a body portion of the vehicle and the positionof each wheel relative to the body and provides this information to a computer. The computer computes the forces required at each wheel and controls the digitalhydraulic actuator at each wheel by adjusting in increments the force applied ateach actuator between the wheel and the body to maintain the body portion of the vehicle in a substantially stable position. Preferably the hydraulic actuator used in the suspension system will be, formed by an assembly including a first element, a cylinder, a body section and a chamber. The first element is providedwith a first set of a plurality of different sized piston cavities and piston elements which cooperate with a second set of piston elements and piston cavities respectively formed on a second element. The second element forms a piston in cylinder. The body sides incorporates preferably in symmetrical relationship around the axis, of the assembly a plurality of valves, one valve for each of the pairs of cooperating pistons and cavities. A piston divides the chamber into a high pressure reservoir and a low pressure reservoir with the piston being urgedtoward the high pressure reservoir to maintain a difference in pressure between the high and low pressure reservoirs. Passages connect each of the valves to thehigh and low pressure reservoir and each valve with respective of the cavity adapted to selectively connect its respective cavity to either the high pressurereservoir or the low pressure reservoir.
