Suspension system integration with advanced driver assistance system

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.

A suspension system of a vehicle, comprising:

• a plurality of dampers connected in fluid communication with each other and a plurality of comfort valves via a plurality of hydraulic circuits;
• 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 plurality of comfort valves 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, retrieve at least one of a target roll stiffness, a target pitch stiffness, and a target pressure of the suspension system, and calculate at least one of an effective roll stiffness and an effective pitch stiffness of the suspension system based on said real-time data;
• a driver assistance system arranged in electronic communication with said suspension control unit (SCU);
• and
• said driver assistance system including a processor and memory configured to generate and update a vehicle stability model based on a combination of said real-time data and at least one of said target roll stiffness, said target pitch stiffness, said effective roll stiffness, and said effective pitch stiffness,
• wherein said driver assistance system is programmed to determine if the vehicle can complete an initiated turn without oversteer or understeer based on at least one of said target roll stiffness, said target pitch stiffness, said effective roll stiffness, and said effective pitch stiffness, 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, and send a request to said suspension control unit (SCU) for a new comfort valve setting corresponding to said different target stiffness in response to determining that the vehicle can complete the initiated turn at said different target stiffness without oversteer or understeer,
• wherein said suspension control unit (SCU) is programmed to initiate said new comfort valve setting corresponding to said different target stiffness by actuating at least one comfort valve in said plurality of comfort valves based on said new comfort valve setting.
