HITCH ANGLE DETECTION USING AUTOMOTIVE RADAR

A trailer detection system for a vehicle includes a radar system outputting object point location data to a rear of the vehicle and a controller. The controller receives the object point location data and determines a position of an edge of the trailer relative to the vehicle by processing the objec...

Zusammenfassung:	A trailer detection system for a vehicle includes a radar system outputting object point location data to a rear of the vehicle and a controller. The controller receives the object point location data and determines a position of an edge of the trailer relative to the vehicle by processing the object point location data from the radar system at a reduced threshold relative to use of the data in detecting a vehicle and filters out object point location data not correlated with the edge of the trailer based on object point location data persistence during driving of the vehicle. The controller further correlates the determined position of the edge of the trailer relative to the vehicle to determine an angle of the trailer relative to the vehicle about a coupling point.
