Abstract
In a method for stabilizing a vehicle in extreme driving situations, in particular when understeering while cornering, multiple wheels are decelerated in order to reduce the driving speed. A maximum cornering force of the wheels and thus a minimal curve radius may be achieved if in particular the rear wheels are decelerated and a higher braking torque is applied on the rear wheels than on the front wheels and in the process in particular the outside front wheel remains highly underdecelerated.

13. A method for stabilizing a vehicle in an unstable driving situation, wherein the unstable driving situation includes understeering while cornering, the method comprising:
braking a plurality of wheels of the vehicle in order to reduce a driving speed of the vehicle, wherein a braking torque applied to at least one rear wheel of the vehicle is greater than a braking torque applied to at least one front wheel of the vehicle. - View Dependent Claims (14, 15, 16, 17, 18)

19. A device for stabilizing a vehicle in an unstable driving situation, wherein the unstable driving situation includes understeering while cornering, comprising:
-
a sensor system configured to detect a plurality of driving condition variables; and
a control unit configured to process sensor system signals and determine whether a trigger threshold is exceeded, wherein, if the trigger threshold has been exceeded, the control unit triggers a plurality of braking actuators associated with a corresponding plurality of wheels of the vehicle in order to perform a braking intervention to decelerate the vehicle, wherein the braking intervention includes applying a greater braking torque to at least one rear wheel of the vehicle than to at least one front wheel of the vehicle. - View Dependent Claims (20, 21, 22, 23, 24)
