Claim 8:
9. A method of controlling a suspension system of a vehicle, comprising:
connecting a plurality of dampers to each other and a plurality of comfort valves via a plurality of hydraulic circuits;
retrieving at least one of a target pitch stiffness and a target pressure from a suspension control unit (SCU) of the suspension system;
monitoring real-time data from at least one onboard sensor or system, the real-time data including data reflecting at least one of fluid pressure within at least one of the hydraulic circuits, damper displacement for at least one of the dampers, longitudinal acceleration of the vehicle, and vehicle speed;
calculating an effective pitch stiffness of the suspension system based on the real-time data;
reporting at least one of the target pitch stiffness and the effective pitch stiffness to a driver assistance system;
generating and updating a vehicle stability model in the driver assistance system based on a combination of the real-time data and at least one of the target pitch stiffness and the effective pitch stiffness;
utilizing the vehicle stability model to determine if a different target stiffness should be implemented based on an initiated throttle input or an initiated brake input;
sending a request from the driver assistance system to the suspension control unit (SCU) for a new comfort valve setting corresponding to the different target stiffness in response to determining that a different target stiffness should be implemented for the initiated throttle input or initiated brake input; and
initiating the new comfort valve setting corresponding to the different target stiffness by actuating at least one comfort valve in the plurality of comfort valves based on the new comfort valve setting.
