Abstract: An apparatus and a method for controlling vehicle suspension, which controls a variable damper in consideration of virtual tire damping, may include a variable damper which is installed between a vehicle body and a wheel, a first acceleration sensor which is installed at each corner of the vehicle body to measure a vehicle body corner vertical acceleration, a second acceleration sensor which is installed to each wheel to measure a wheel vertical acceleration, and a controller that estimates a road surface roughness based on the vehicle body corner vertical acceleration and the wheel vertical acceleration, determines a virtual tire damping required damping force based on the estimated road surface roughness, and adjusts a damping force of the variable damper based on the determined virtual tire damping required damping force.

Abstract: A motion control system is coupled to a first mass and a second mass and is configured to regulate motion of the first mass with respect to the second mass. The motion control system is configured to increase a contact area between the second mass and a surface on which the second mass rests by increasing a displacement of the motion control system from a neutral position in a direction toward the first mass.

Abstract: A suspension system and associated control methods for improving the effectiveness of driver assistance systems is disclosed where the driver assistance systems can generate and send requests to a suspension control unit (SCU) of the suspension system to actuate (e.g., close) one or more comfort valves in the suspension system to increase the roll stiffness and/or pitch stiffness of the suspension system when the driver assistance systems are taking corrective action. As part of a two-way communication between the suspension control unit (SCU) and the driver assistance systems, the suspension control unit (SCU) communicates target stiffnesses and/or calculated effective stiffnesses to the driver assistance systems, which is used to update the vehicle stability models used by the driver assistance systems.

Abstract: A shock for a vehicle includes a tube elongated along an axis. A piston is disposed in the tube and is moveable relative to the tube along the axis. A rod is connected to the piston. A floating piston is spaced from the piston along the axis and is moveable relative to the tube along the axis. The tube defines a working chamber between the piston and the floating piston. The tube defines a gas chamber. The floating piston separates the gas chamber from the working chamber. The floating piston has a housing slideably engaged with the tube and a membrane fluidly separating the working chamber from the gas chamber. The membrane is flexible relative to the housing.

Abstract: An ECU includes: a road surface height measurer which measures road surface heights at three or more points along a vehicle-width direction in front of a tire mounted on a wheel; a position detector which detects a position at which a difference of the road surface height from an adjacent road surface height is equal to or larger than a predetermined threshold among the road surface heights at three or more points measured by the road surface height measurer; and a road surface condition determiner which excludes a value of the road surface height at the position at which the difference detected by the position detector is equal to or larger than the predetermined threshold, and determines a condition of the road surface based on the road surface heights at positions at each of which the difference from an adjacent road surface height is smaller than the predetermined threshold.

Abstract: An adaptive suspension damper may include a body defining a working chamber, and a sleeve operably coupled to the body to alternately open the working chamber to enable a working fluid to enter or leave the working chamber relative to compression and rebound events experienced at the adaptive suspension damper, and close the working chamber to enable the piston head to act as a hydraulic ram inside the working chamber to selectively adjust a position of a piston head in the working chamber to adjust a height of a corner of a vehicle at which the adaptive suspension damper is located.

Abstract: A suspension system including four dampers where each damper includes compression and rebound chambers. The suspension system has four hydraulic circuits, each including a cross-over hydraulic line that extends between dampers located at opposite corners of the vehicle (i.e., between the front left and back right dampers or between the front right and back left dampers). The suspension system further includes four electromechanical comfort valves that open and close four bridge hydraulic lines that extend between the cross-over hydraulic lines at each corner of the vehicle. Each cross-over hydraulic line is connected to a manifold assembly by a corresponding manifold hydraulic line. The manifold assembly includes four manifold valves that are connected to a pump assembly and two manifold comfort valves. All six comfort valves are electromechanical valves that can be actuated to control the roll and pitch of the vehicle during cornering, braking, and acceleration.
