Zusammenfassung:A device for compensating for a disturbance yaw moment in a vehicle having at least two wheel-individual drives is described. In particular in vehicles having multiple wheel-individual electric drives, wear or heavy use may result in a defect of a single drive. Since this drive is coupled to a single wheel of the vehicle, a strong disturbance yaw moment may be generated thereby which may result in the vehicle breaking away if countermeasures are not taken. It is provided to compensate for the disturbance yaw moment at least partially by effectuating a compensation yaw moment by retarding one or multiple of the other wheels of the vehicle in a targeted manner, when an event is detected which indicates a disturbance yaw moment of the vehicle and in which one wheel of the vehicle is excessively retarded due to a defect on a wheel-individual drive assigned to the wheel.
