Method and device for identifying and eliminating the risk of rollover
First Claim
1. A device for detecting and rectifying a danger of a rollover of a vehicle about an axis oriented in a longitudinal direction of the vehicle, the device comprising:
- a plurality of actuators and driver information systems;
an arrangement configured to determine a variable describing transverse dynamics of the vehicle;
an arrangement configured to compare the variable describing the transverse dynamics of the vehicle with at least one characteristic threshold value; and
a regulating system configured to output signals for controlling the actuators;
wherein, the regulating system is configured to perform the following if the variable describing the transverse dynamics of the vehicle is equal or greater than the characteristic threshold value;
a) restrict certain sets of possible combinations of output signal values and prevent the output signals from being transmitted to the plurality of actuators; and
b) activate at least one intervention for stability of the vehicle, the at least one intervention having an intensity that increases with an increasing value of the variable describing the transverse dynamics such that at least three intensity stages of the at least one intervention occur, a reduction of a maximum possible engine torque occurring in with the increase in the variable describing the transverse dynamics.

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.
