1. A reverse driving assistance system for assisting a driver in steering a vehicle combination of a towing vehicle having a trailer, comprising:
an operator control element for specifying a target articulation angle;
a sensor for sensing a current articulation angle of the vehicle combination;
a display unit for displaying the specified target articulation angle; and
an electronic control unit which is operatively coupled to the operator control element, the sensor, and the display, wherein the control unit comprises:
(a) an evaluation unit for detecting an implausible specification of the target articulation angle, and
(b) a protection unit for restricting functionality of the reverse driving assistance system when an implausible specification of the target articulation angle is detected, wherein
the control unit is configured such that an implausible specification of the target articulation angle is detectable at least by sensing a frequency of a change of direction of the operator control element within a specified time and by comparing the sensed value with a defined threshold value, and
the reverse driving assistance functionality is restricted when an implausible specification of the target articulation angle is detected as a result of the threshold value being exceeded.
