Abstract
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.
Claims15
A method for assisting reverse driving of a combination, the combination comprising a motor vehicle with a hitch and a trailer with a drawbar rotatably attached to the hitch, the method comprising:
- determining an actual value for a hitch angle of the combination by a computing unit of the combination depending on sensor data generated by a hitch angle sensor system of the combination;
- determining a hitch length of the trailer, which is given by a distance between a trailer body of the trailer and the hitch, by the computing unit depending on environmental sensor data generated by an environmental sensor system of the combination;
- determining a collision value for the hitch angle by the computing unit depending on the hitch length;
- and
- triggering a safety measure by the computing unit depending on the actual value and the collision value.
A driver assistance system for assisting reverse driving of a combination, wherein the combination comprises a motor vehicle with a hitch and a trailer with a drawbar rotatably attached to the hitch, the driver assistance system comprising:
- a hitch angle sensor system, which is configured to generate sensor data;
- a computing unit, which is configured to determine an actual value for a hitch angle of the combination depending on the sensor data;
- and
- an environmental sensor system configured to generate environmental sensor data
- wherein the computing unit is configured to:
- determine a hitch length of the trailer given by a distance between a trailer body of the trailer and the hitch depending on the environmental sensor data,
- determine a collision value for the hitch angle depending on the hitch length, and
- trigger a safety measure depending on the actual value and the collision value.
