A steering angle is calculated with the electronic control unit based upon the requested hitch angle rate of change, wherein the steering angle will allow movement of the vehicle-trailer unit in the reverse direction to obtain the requested hitch angle rate of change; and a request is sent to a steering system to provide the steering angle.

According to a method for assisting reverse driving of a combination (1), an actual value for a hitch angle of the combination (1) is determined by a computing unit (6) depending on sensor data generated by a hitch angle sensor. A hitch length of a trailer (3), given by a distance between a trailer body (11) and a hitch (7) of a vehicle (2), is determined depending on environmental sensor data of the combination (1). A collision value for the hitch angle is determined by the computing unit (6) depending on the hitch length, and the safety measure is triggered by the computing unit (6) depending on the actual value and the collision value for the hitch angle.
