Abstract
Described is a device for stabilizing a vehicle in critical driving situations, including a vehicle dynamics control system having a control unit, including a vehicle dynamics control algorithm, and at least one actuator and an additional vehicle stability system having an associated actuator. Vehicle dynamics control may be executed in a particularly simple and trouble-free manner when the vehicle dynamics control algorithm is retrofitted with a distribution function which derives an actuating request for an actuator of the vehicle dynamics control system as well as an actuating request for at least one actuator of the vehicle stability system from a controller output variable.
