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