Abstract

A device and the method are for the recognition and rectification of the danger of rollover of a vehicle, outfitted with a regulating system, about a vehicle axis oriented in the longitudinal direction of the vehicle. The regulating system controls actuators using its output signals in accordance with the output signal values. A variable describing the transverse dynamics of the vehicle is determined for the recognition of the danger of a rollover. This variable describing the transverse dynamics of the vehicle is compared to at least one characteristic value, e.g., a threshold value. In the case in which the variable describing the transverse dynamics of the vehicle is greater than, or equal to the characteristic value, the number of all possible combinations of output signal values that may be supplied to the actuators by the regulating system for stability regulation is restricted.
