Claim 0:
1. 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 roll 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, lateral acceleration of the vehicle, vehicle speed, and steering wheel angle;
calculating an effective roll stiffness of the suspension system based on the real-time data;
reporting at least one of the target roll stiffness and the effective roll 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 roll stiffness and the effective roll stiffness;
utilizing the vehicle stability model to determine if the vehicle can complete an initiated turn without oversteer or understeer based on the target roll stiffness or the effective roll stiffness;
utilizing the vehicle stability model to determine if the vehicle can complete the initiated turn at a different target stiffness without oversteer or understeer if the vehicle cannot complete the initiated turn without oversteer or understeer at the target roll stiffness or the effective roll stiffness;
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 the vehicle can complete the initiated turn at the different target stiffness without oversteer or understeer; 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.
