Abstract
A ride control system includes a shock absorber having a movable piston that divides the shock absorber into a lower and an upper volume and a center check valve that allows fluid to flow from the upper to the lower volume. A back pressure actuator provides a selectable back pressure to the lower volume. Three two way valves and a check valve allow the lower and upper volumes to be selectively coupled to either the selectable back pressure or a shock absorber fluid reservoir to provide passive, semi-active, or active ride control. The back pressure actuator pressurizes a hydraulic accumulator when shock absorber fluid flows into the back pressure actuator to provide energy recovery.
