Abstract

The invention relates to a reversing aid for supporting the driver of a motor vehicle, particularly when parking, comprising at least one transmitter (12), arranged at the rear end region (10) of the motor vehicle, for emitting measuring beams (14) into the rear danger zone, at least one receiver (16, 16a, 16b), arranged at the rear end region (10) of the motor vehicle, for receiving beams (20) reflected at at least one detected object (18), a distance-measuring device for determining the distance (A) between the vehicle and the detected object (18), and a display device (22) for optically representing the distance (A) from the detected object (18). Furthermore, the reversing aid comprises a measuring beam horizontal guidance system for the purpose of periodically scanning a predetermined angle range in the horizontal plane, an evaluation device for determining the position of the detected object in the horizontal plane relative to the vehicle rear end and to the extent of the width of the detected object, and a display screen (24) for pictorially representing the position and the extent of the width of the detected object in the horizontal plane relative to the vehicle rear end (1…
