Method for determining an actual level of a vehicle
First Claim
1. 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.

Abstract
A method for determining an actual level of a vehicle, includes determining an actual level of the vehicle as a function of a distance between at least one wheel of the vehicle and a superstructure of the vehicle, wherein the distance is determined by means of a signal detected by at least one chassis sensor, wherein the signal includes at least signal portions that correspond to an own movement of the vehicle and signal portions that correspond to an excitation by a road on which the vehicle actually drives; filtering the signal portions corresponding to the own movement of the vehicle 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 signal portions that correspond to the own movement of the vehicle and the signal detected by the at least one chassis sensor.

7. A vehicle, comprising:
-
a control device configured to determine an actual level of the vehicle via a distance between at least one wheel carrier of the vehicle and a superstructure of the vehicle and to determine the distance by means of a signal detected by at least one chassis sensor, said at least one chassis sensor being a spring travel sensor coupled to a spring damper mass system of an active body suspension, said signal including a first signal portion which 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 a road on which the vehicle actually drives, said control device being further configured to filter the first and second signal portions out of the signal detected by the at least one chassis sensor by means of at least one filter function and to determine 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 and to provide the actual level of the vehicle to a control function of at least one component of the vehicle to regulate the distance between the superstructure and the at least one wheel carrier. - View Dependent Claims (8)

9. A control device for installation in a vehicle, said control device being configured to determine an actual level of the vehicle via a distance between at least one wheel carrier of the vehicle and a superstructure of the vehicle and to determine the distance by means of a signal detected by at least one chassis sensor being a spring travel sensor coupled to a spring damper mass system of an active body suspension, said signal including a first signal portion which 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 a road on which the vehicle actually drives,
said control device being further configured to filter the first and second signal portions out of the signal detected by the at least one chassis sensor by means of at least one filter function and to determine 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 and to provide the actual level of the vehicle to a control function of at least one component of the vehicle, and to regulate the distance between the superstructure and the at least one wheel carrier.
