Abstract:
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.
