A method for changing a ride height position of a motor vehicle comprises measuring a respective relative distance of a vehicle superstructure from corresponding wheels, with spring travel sensors and transmitting a respective spring travel signal to an electronic open-loop and closed-loop control device of the motor vehicle. The spring travel signals pass through a frequency filtering in the electronic open-loop and closed-loop control device The frequency filtering initially comprising a bandpass filtering which splits the spring travel signal into a signal component excited by the wheel and a signal component excited by the vehicle superstructure. The signal component excited by the vehicle superstructure is filtered out, the frequency filtering then comprising an absolute value conversion of the bandpass-filtered spring travel signal and subsequently a low-pass filtering.

Method for changing a ride height position of a motor vehicle using an actively adjustable chassis

A method for monitoring and controlling a chassis pneumatic ride-height control system. Repeatedly measuring a current height of the chassis; detecting when the current height of the chassis exceeds at least one predefined height threshold. A time interval threshold is associated with the height threshold; repeatedly measuring a time interval in which the current height of the chassis exceeds the predefined height threshold; detecting when the measured lime interval exceeds the predefined time interval threshold associated with the predefined height threshold; repeatedly checking whether both the height threshold and the associated time interval threshold are exceeded, and if so, preventing the current height of the chassis from rising further and/or increasing stability of the chassis; deactivating the measures when the repeated check shows that the current height of the chassis is below the at least one height threshold and the associated time interval threshold.

Method for monitoring and controlling a pneumatic ride-height control system of a chassis system

A computer-implemented method for carrying out a plausibility check for recognizing a loss in load-bearing capacity in at least one suspension strut of a suspension system of a motor vehicle chassis during the operation of the chassis. Target-actual comparisons of measured suspension paths with evaluation parameters having predetermined critical threshold values calculated from the suspension paths are performed. In the event that the predetermined critical threshold values are exceeded or not attained, a recognition signal is set for a possible loss in load-bearing capacity.

Disclosed is a gas spring/damper unit () having at least one movably mounted displacement piston () and two displacement chambers () whose volume increases or diminishes according to the direction of travel of the displacement piston () and which are interconnected via overflow ducts () in which throttle valves (&#x2033;') are disposed. Several throttle valves (&#x2033;&#x2032;) having different valve characteristics are positioned so as to be effective in one direction of flow. One throttle valve () is designed for damping eigenfrequencies ranging from 1 to 1.5 Hz while another throttle valve (&#x2032;) is designed for damping eigenfrequencies ranging from 10 to 40 Hz.

Pneumatic spring damper unit

A method controls the damper current of a damper of a motor vehicle. The damper is adjustable by an electrical current and the permissible change of the current per time interval is delimited by a limit.
