Abstract
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.
