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.

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

Roll stabilization system for a motor vehicle

A control device for an adjustable chassis system includes a connection to at least one sensor arrangement which provides at least one vehicle condition parameter of a vehicle. The measured vehicle condition parameter is spatially related to a position outside of the control device. The sensor arrangement is arranged inside the control device and forms a virtual miniature measurement plane which is extrapolated to an actual measurement plane.

A valve assembly for a vibration damper includes a valve housing, an actuator for driving an adjustable valve part, and a circuit arrangement having an opening which provides access to the actuator, wherein the actuator has a coil. The actuator and the circuit arrangement are arranged in the housing. A coating arranged on the circuit arrangement is shaped and dimensioned to position the circuit arrangement at a fixed position and orientation relative to the actuator. An outer plastic jacket is arranged over the coating of the circuit arrangement and encloses the coil of the actuator, so that the outer plastic jacket protects both the circuit arrangement and the coil.

Valve assembly with an integrated circuit arrangement

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 (t) is determined and stored as a gap value. A second distance signal difference is determined at a second time (t) for a new gap value. When the wheel-side axle part reaches a reference position with respect to the vehicle body during the relative movement between the axle part on the wheel side and the vehicle body, a switching signal is generated and is used as a reference signal for determining the absolute position of the wheel side axle part along with the difference calculations.
