Method for determining an actual level of a vehicle

A method for determining an actual level of a vehicle to regulate a distance between a superstructure and a wheel carrier, said method comprising:

• determining an actual level of the vehicle as a function of a distance between the wheel carrier of the vehicle and the superstructure of the vehicle,
• wherein the distance between the wheel carrier and the superstructure is determined by means of a signal detected by at least one chassis sensor, wherein said at least one chassis sensor is a spring travel sensor coupled to a spring damper mass system of an active body suspension, said signal including a first signal portion that corresponds to an own movement of the vehicle, a second signal portion that corresponds to extended unevennesses on a road on which the vehicle actually drives, and a third signal portion that corresponds to an excitation by the road on which the vehicle actually drives;
• filtering the first and second signal portions out of the signal detected by the at least one chassis sensor by means of a filter function;
• calculating the actual level of the vehicle from a difference between the filtered signal without the first and second signal portions and the signal detected by the at least one chassis sensor;
• providing the actual level of the vehicle to the active vehicle body suspension system;
• and
• actively regulating the distance between the superstructure and the wheel carrier by the active vehicle body suspension system.
