ABSTRACT:
A digital suspension 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 position of each wheel relative to the body provides this information to a computer. The computer computes the forces required at each wheel and controls the digital hydraulic actuator at each wheel by adjusting in increments the force applied at each actuator between the wheel and the body to maintain the body portion of the vehicle in a substantially stable position.
