Abstract: A method for operating a damper valve in order to control a damper force of a damper in an active chassis of a vehicle, wherein the damper valve includes a pilot valve for controlling a main spool. The method includes determining a target pressure necessary for a target damper force, in a first damper chamber of the damper; determining a valve flow through a damper valve inlet of the damper valve on the basis of a damper flow, generated by a damper movement, from the first damper chamber and on the basis of a measured pump flow of a pump; determining a main spool opening distance in such a way that, with an applied main spool flow through the main spool opening distance, the target pressure is present as the back pressure in the first damper chamber.

Abstract: Systems, computer-implemented methods, and computer program products relating to jerk of a vehicle damper are provided. According to an embodiment, a system can comprise a memory that stores computer executable components and a processor that executes the computer executable components stored in the memory. The computer executable components can comprise a control signal determination component that determines a new damping coefficient for a vehicle damper and determines a rate of change of acceleration from a current damping coefficient of the vehicle damper to a new damping coefficient for the vehicle damper, wherein the rate of change is based on a movement signal of the vehicle damper, and a damper adjustment component that adjusts to the new damping coefficient at the rate of change.

Abstract: A damping system includes a first magnetic damper pair mounted on a suspension system of a vehicle. The first magnetic damper pair includes a first magnet mounted on a first surface of a body of the vehicle and a second magnet mounted on a first moveable component of the suspension system coupled to a wheel of the vehicle. A sensor is mounted on the body of the vehicle or the wheel. A damping system control module is configured to receive, from the sensor, inputs indicative of a velocity and a displacement of the wheel relative to the body of the vehicle, calculate an amount of force to generate between the magnetic damper pair in a direction opposite a direction of movement of the wheel, and control supply of current to at least one of the first magnet and the second magnet to generate the calculated amount of force.

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: A method is provided for diminishing the effect of roadway anomalies on a vehicle by dynamically adjusting an actuating element for regulating damper forces of a vibration damper of a vehicle wheel when passing over a roadway anomaly, in particular a pothole, wherein, when the falling edge of the roadway anomaly is reached, the actuating element is switched into its hardest setting and, when the rising edge of the roadway anomaly is reached, the force request is set equal to 0 and, thereafter, a force request is calculated based on the parameters of the vehicle and the suspension and is transmitted to the damping.
