一种车辆拖车导引系统,包括电子控制单元(ECU)和设置在车辆处的后部倒退摄像头。人机界面(HMI)可以以(i)拖车左倒退模式、(i)拖车顺直倒退模式和(iii)拖车右倒退模式操作。响应于驾驶员对拖车左倒退模式或拖车右倒退模式的选定,ECU将拖车舌部向左或向右的期望拖车角度设定为与输入装置的驾驶员所选设定相称的角度。响应于驾驶员对拖车顺直倒退模式的选定,ECU将期望拖车角度设定为零度角。ECU在车辆正在倒退拖车时控制车辆的动力转向系统来使车辆转向以倒退拖车,从而使所确定的拖车角度与所设定的期望拖车角度一致。
A vehicular trailer guidance system includes an electronic control unit (ECU) and a rear backup camera disposed at a vehicle. A human machine interface (HMI) is operable in (i) a trailer left-backup mode, (i) a trailer straight-backup mode and (iii) a trailer right-backup mode. Responsive to selection by the driver of the trailer left-backup mode or trailer right-backup mode, the ECU sets a desired trailer angle of the trailer tongue leftward or rightward to an angle that is commensurate with a driver-selected setting of an input device. Responsive to selection by the driver of the trailer straight-backup mode, the ECU sets the desired trailer angle to a zero degree angle. The ECU, while the vehicle is backing up the trailer, controls the power steering system of the vehicle to steer the vehicle to back up the trailer to have the determined trailer angle coincide with the set desired trailer angle.
