Abstract: A suspension system and associated control methods for improving comfort by disabling passive pitch stiffness in the suspension system by holding open electromechanical comfort valves positioned in a manifold assembly of the suspension system. The manifold comfort valves are held open to disable the passive pitch stiffness of the suspension system if the vehicle is traveling down a rough road or if the vehicle is approaching a discrete road event like a pot-hole or speed bump. Deactivation of the passive pitch stiffness of the suspension system is determined based on road classification information, saved road events, and/or real-time vehicle data from on-board sensors. The suspension system therefore reduces pitch angles during pitch events induced by inertial forces caused by driver inputs and disables the pitch stiffness when the pitch event is caused by road inputs.

Abstract: A suspension system and associated control methods that reduce temperature related fluctuations in the internal pressures and stiffness of the suspension system. A manifold assembly is connected in fluid communication with a plurality of dampers via hydraulic circuits and a pump assembly via a pump hydraulic line. Onboard sensors generate real-time data regarding the vehicle. A suspension control unit, arranged in electronic communication with the aforementioned components, monitors the real-time data, sets a target stiffness and a target pressure, calculates an effective stiffness based on the real-time data, determines if the effective stiffness is above or below the target stiffness and sets a new target pressure accordingly by making stepwise decreases or increases until the new target pressure is reached.

Abstract: The present disclosure provides a method of manufacturing a damper for a vehicle. The method includes forming a groove on an outer surface of a first component in a first annular region. The first component is tubular. The method further includes inducing a compressive residual stress in a second annular region. The second annular region is at least partially aligned with the first annular region along a longitudinal axis of the first component. The method further includes coupling a second component to the first component. Surfaces of the first component and the second component directly engage one another at an interface. The second component is axially aligned with and radially surrounding at least a portion of the first annular region. In some configurations, forming the groove and inducing the compressive residual stress are performed concurrently, such as by low plasticity burnishing.
