Upon initiation of trailer-hitching, an image is obtained of an area behind and in a horizontal plane with respect to a vehicle, the area including a rearwardly extending trailer hitch, with a hitch ball mounted thereto, mounted to the vehicle. The hitch ball is located in the image. An overshoot zone, having a length extending from a vehicle rear bumper to a nearest point on the vehicle hitch ball and having a width that is a sum of a diameter of the hitch and two times a lateral offset, is defined within the area, as is a misaligned zone having a border extending from the vehicle rear bumperto a line tangent to a rearmost point of the hitch ball. A vehicle action is caused upon determining that the trailer coupling is detected in the overshoot zone or the misaligned zone.
搭扣机动。在开始挂车挂钩时,获得相对于车辆在水平面后面和在水平面中的区域的图像,该区域包括向后延伸的挂车挂钩,该挂车挂钩安装在其上并安装在车辆上。挂钩球位于图像中。在该区域内定义了一个过冲区域,该区域的长度从车辆后保险杠延伸到车辆挂钩球上的最近点,并且宽度是挂钩直径和横向偏移的两倍。是未对准区域,其边界从车辆后保险杠延伸到与挂钩球的最后一点相切的线。在确定在超调区域或未对准区域中检测到挂车联接时,引起车辆动作。
