A damping control system includes: a damping chamber connected to one of (a) a body of a vehicle and (b) a wheel of the vehicle; a piston that is slidably disposed within the damping chamber and that includes: a piston rod that is connected to the other one of (a) the body of the vehicle and (b) the wheel of the vehicle; and a plunger that is connected to the piston rod and that divides the damping chamber into a first chamber and a second chamber; a first valve that regulates hydraulic fluid flow out of the first chamber; and a valve control module configured to selectively close the first valve when a position of the plunger is between (a) a first reference position within the first chamber and (b) a first end stop of the damping chamber that defines a boundary of the first chamber.

End stop damping control systems and methods

A control system includes: a target volume module configured to determine a target volume of hydraulic fluid within a suspension system of a vehicle based on a target pressure of the hydraulic fluid within the suspension system; a volume command module configured to generate a volume command based on the target volume and a present volume of the hydraulic fluid within first and second circuits; a command module configured to, based on the volume command, generate: a pump command for an electric hydraulic fluid pump; and first and second valve commands for first and second seat valves that regulate hydraulic fluid flow to and from the first and second circuits, respectively; a valve control module that actuates the first and second seat valves based on the first and second valve commands, respectively; and a pump control module that controls operation of the pump based on the pump command.
