Abstract: A method for operating a motor vehicle with a chassis arrangement having at least two vibration dampers. A body control is carried out at least partially with the vibration dampers. The chassis arrangement further has at least one stabilizer. During transverse accelerations below a threshold acceleration the stabilizer contributes to the body control less than the vibration dampers and contributes more than the vibration dampers from the threshold acceleration upward.

Abstract: A method of operating a motor vehicle with a chassis system comprising at least two, preferably four vibration damper includes carrying out a body control and a wheel control with the chassis system, and controlling the energy supply for the chassis system via an energy control arrangement. A motor vehicle performing the method is also disclosed.

Abstract: A roll stabilization system (1) for a motor vehicle which has a DC voltage converter (6) associated with an electric roll stabilizer (2). By way of the DC voltage converter, a feed voltage can be transformed into a supply voltage for the roll stabilizer (2). To produce as compact a structure as possible, the DC voltage converter (6) is integrated in the electric roll stabilizer (2).

Abstract: A vibration damper with a piston, a piston rod fastened to the piston, a working chamber divided by the piston into a first working chamber and second working chamber, and a generator drivable by movement of the piston rod. The damping force of the vibration damper can be influenced by energization of the generator. An energizable component part is provided that short-circuits the windings of the generator when unenergized and cancels the short circuit when energized.

Abstract: A vibration damper with a damping force adjusting device and a height adjusting device for changing the axial position of a piston of the vibration damper, characterized in that the damping force adjusting device is adjusted depending on at least one operating parameter of the height adjusting device, and when there is a change in the at least one operating parameter there is also a change in at least one operating parameter of the damping force adjusting device. A method of operating a vibration damper with a controller and a motor vehicle including such vibration damper and controller is also disclosed.

Abstract: Energy-recuperating vibration damper having a cylinder in which a displacer executes a limited operating movement in a working chamber so that a pressurized fluid is supplied to a fluid motor which drives a generator. A compensation chamber compensates for a change in volume of the pressurized fluid. A pressure accumulator is provided in addition to the compensation chamber, which pressure accumulator communicates with and is parallel-connected to the fluid motor.

Abstract: Gas spring includes a cover which works together with a rolling bellows and a bottom part to form a gas-filled spring space, where at least part of the outside surface of the rolling bellows is covered by a sleeve. The sleeve provides a receptacle for at least one sensor which detects the stroke position of the gas spring.

Abstract: A first acceleration sensor is arranged on a vehicle body for detecting an acceleration signal of the vehicle body and a second acceleration sensor is arranged on a wheel-side axle part for detecting an acceleration signal of the wheel-side axle part, the vehicle body and the wheel-side axle part execute relative movement with respect to each other. The wheel acceleration signal and the body acceleration signal are each integrated twice to form respective distance signals. The difference between the two distance signals at a first time (t0) is determined and stored as a gap value. A second distance signal difference is determined at a second time (t1) for a new gap value.

Abstract: A piston-cylinder unit includes a cylinder with a piston rod guide and a piston rod with a piston axially movably mounted in the cylinder so that the piston rod runs through a hole in the piston rod guide. A movement determination device comprising a transmitter portion and a receiver portion determine the movement of the piston from the travel time of waves generated by the transmitter portion. The movement determination device is arranged inside the piston rod guide, and waves reflected by the piston-piston rod component group are analyzed to determine the movement of this component group.
