The invention provides 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 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.
本公开提供“使用汽车雷达的挂接角检测”。一种用于车辆的挂车检测系统包括输出车辆的后部的对象点位置数据的雷达系统和控制器。所述控制器接收所述对象点位置数据,并且通过处理来自所述雷达系统的在相对于在检测车辆中所述数据的使用的减小的阈值下的所述对象点位置数据来确定所述挂车的边缘相对于所述车辆的位置并基于在所述车辆的行驶期间的对象点位置数据持久性过滤掉与所述挂车的所述边缘不相关的对象点位置数据。所述控制器进一步关联所述挂车的所述边缘相对于所述车辆的所确定位置以确定所述挂车关于联接点相对于所述车辆的角度。
