Abstract: A ride control suspension control system having suspension control units with a damper and a single pressure regulator that controls dampening in both the compression and rebound chambers of the damper. The fluid control circuit may include a plurality of check valves that coordinate the flow of fluid to and from both chambers through the pressure regulator. In one embodiment, the system includes a central controller that receives input from a variety of sensors and directly controls operation the pressure regulators in each of the suspension control units without the need for any remote processors. The ride control suspension system may also include wheel position sensors that are external to the accumulator.
