| Abstract: |
A method and an apparatus relate to the detection of a tilt tendency of a vehicle about a vehicle axis oriented in the longitudinal direction of the vehicle. For this purpose, for at least one wheel, a variable describing the wheel rotation speed and at least one variable representing the transverse dynamics of the vehicle are ascertained. As a function of one of the variables representing the transverse dynamics of the vehicle, braking torques and/or drive torques are briefly generated and/or modified at at least one wheel. While the braking torques and/or drive torques at the at least one wheel are being briefly generated and/or modified, and/or after they have been briefly generated and/or modified, a variable which quantitatively describes the wheel behavior is determined for that at least one wheel, as a function of the variable describing the wheel rotation speed of that wheel. As a function of that variable quantitatively describing the wheel behavior of that wheel, a determination is made as to whether there is a tilt tendency of the vehicle about a vehicle axis oriented in the longitudinal direction of the vehicle.

What is claimed is:
1. A method for detecting a tilt tendency of a vehicle about a vehicle axis, the vehicle axis being oriented in a longitudinal direction of the vehicle, the method comprising the steps of:
- (a) ascertaining, for at least one wheel, a variable describing a wheel rotation speed;
- (b) ascertaining at least on variable representing transverse dynamics of the vehicle;
- (c) at least one of generating and modifying at least one of a braking torque and drive torque at the least one wheel, the at least one of the generating and the modifying being a function of the at least one variable representing the transverse dynamics of the vehicle;
- (d) determining a variable describing quantitatively a wheel behavior for the at least one wheel at least one of during and after step (c), the variable describing quantitatively the wheel behavior being a function of at least the variable describing the wheel rotation speed for the at lest one wheel; and
- (e) determining whether the tilt tendency of the vehicle about the vehicle axis is present, the determining of whether the tilt tendency is present being a function of at least the variable describing quantitatively the wheel behavior for the at least one wheel.
