Claim 16:
17. A suspension system of a vehicle, comprising:
a manifold assembly connected in fluid communication with a plurality of dampers via a plurality of hydraulic circuits and connected in fluid communication with a pump assembly via a pump hydraulic line;
said manifold assembly including at least one manifold valve configured to control fluid flow between said pump hydraulic line and said plurality of hydraulic circuits;
said pump assembly including a pump that is arranged in fluid communication with said pump hydraulic line;
at least one onboard sensor configured to generate real-time data regarding the vehicle;
a suspension control unit (SCU) arranged in electronic communication with said at least one manifold valve, said pump, and said at least one onboard sensor;
said suspension control unit (SCU) including a processor and memory configured to monitor said real-time data generated by said at least one onboard sensor and set a target stiffness and a target pressure in said memory,
wherein said suspension control unit (SCU) is programmed to: determine an effective stiffness of the suspension system based on said real-time data, determine if said effective stiffness of the suspension system is above or below said target stiffness, set a new target pressure in said memory of said suspension control unit (SCU) if said effective stiffness is determined to be above or below said target stiffness by making a stepwise decrease or increase to said target pressure, open said at least one manifold valve when said new target pressure is set by said suspension control unit (SCU), energize said pump in a first direction or a second direction to pump hydraulic fluid into or out of said hydraulic circuits of the suspension system until said new target pressure is reached, and close said at least one manifold valve when said new target pressure is reached.
