Abstract

A system for monitoring the area surrounding a vehicle, especially behind the vehicle and/or a connected trailer. The system includes distance sensors, which are arranged in a main plane and in at least one additional plane, for detecting objects in the respective monitoring region that pose a risk of collision and/or that limit passage height and/or width. The system also includes a device that evaluates the distance sensor signals to ascertain the current distance of the vehicle from the detected object and to compare the current distance against a predefinable, vehicle-specific setpoint distance value and to output a warning signal if a predefinable difference value therebetween is not reached. To cover the monitoring region both in area and height, additional distance sensors are arranged in at least one additional plane such that objects that cannot be identified by the sensors in the main plane can be detected over the entire width of the vehicle.
