Patent attributes
A reverse driving assistance system assists a driver in steering a towing vehicle having a trailer. The system has an operating element for specifying a target articulation angle, a sensor device for detecting the current articulation angle of the vehicle-trailer combination, a display unit at least for displaying the specified target articulation angle, and an electronic control unit connected to the aforementioned components. The control unit also has an evaluation unit for recognizing an implausible specification of the target articulation angle and a protection unit for restricting the reverse driving assistance functionality if an implausible target specification is recognized. An implausible specification of the target articulation angle can be recognized at least by detecting the frequency of the change in direction of the operating element within a predetermined time and by comparing the detected value with a defined threshold value. The reverse driving assistance functionality is restricted if an implausible target specification is detected as a result of this threshold value being exceeded.
