Abstract

A method and a device serve to detect a tendency of a vehicle to roll over about a vehicle axis oriented in the longitudinal direction of the vehicle. To do so, a variable describing the wheel rpm is determined for at least one wheel. Furthermore, at least one variable representing the transverse dynamics of the vehicle is determined. For at least one wheel, a variable describing the wheel behavior quantitatively is determined at least as a function of the variable describing the wheel rpm of the corresponding wheel and one of the variables representing the transverse dynamics of the vehicle. Whether the vehicle has a tendency to roll over about a vehicle axis oriented in the longitudinal direction of the vehicle is determined at least as a function of the variable determined for at least one wheel, describing the wheel behavior of this wheel quantitatively. The method and the device for detecting a tendency of a vehicle to roll over about a vehicle axis oriented in the longitudinal direction of the vehicle are used in the context of stabilizing the vehicle.
