## Abstract

A vehicular trailer assist system includes a plurality of vehicle cameras disposed at a vehicle, a trailer camera disposed at a rear portion of a trailer and viewing at least rearward of the trailer, and an electronic control unit (ECU) having a processor operable to process image data captured by the cameras. A display screen displays images of a region rearward of the trailer and includes a touch screen. Responsive to a touch input that is representative of a target location, the ECU, via processing of image data captured by the cameras, determines a path of travel for the vehicle and trailer to follow to maneuver the vehicle and trailer toward the target location. The ECU, responsive to an input indicative of an updated target location, updates the path of travel for the vehicle and trailer to follow to maneuver the vehicle and trailer toward the updated target location.
