Control systems and methods for suspension systems

A control system for a suspension system of a vehicle, the control system comprising:

• a target volume module configured to determine a target volume of hydraulic fluid within the suspension system of the 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 of the suspension system;
• 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, of the suspension system;
• 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 electric hydraulic fluid pump based on the pump command.
