Method and system for preventing a following vehicle from driving up on a vehicle driving directly in front and use of the system

The invention relates to a method for preventing a following vehicle (23) from driving up on a vehicle (22) driving directly in front, wherein the following vehicle (23) detects a behaviour of the vehicle (22) driving directly in front by means of sensor information and a behaviour of at least one vehicle (21) driving in front of the vehicle (22) driving in front by means of vehicle-to-X information, wherein the vehicle-to-x information requests an intervention in the steering means of the following vehicle (23) in the form of a steering angle to be set and/or an intervention in the braking means of the following vehicle (23) in the form of a deceleration to be set in order to prevent driving up on the vehicle, and wherein the steering angle and/or the deceleration requested by the vehicle-to-X information is greater than a steering angle and/or a requested deceleration requested by the sensor information and/or driver inputs. The method is characterized in that the intervention with the steering angle requested by the vehicle-to-X information and/or the requested deceleration is only carried out if said steering angle and/or said deceleration is confirmed by the sensor information and/or by driver inputs. The invention further relates to a corresponding system and use thereof.
