Abstract
A vehicle hitching assistance system including a controller determining a trailer target area to a rear of the vehicle. The trailer target area is positioned within left and right lateral vehicle steering limits, defined in a lateral direction between left and right boundaries respectively spaced inwardly of the left and right lateral vehicle steering limits by one of a system perception factor or a vehicle geometry factor, and defined in a longitudinal direction between a minimum movement limit and a maximum perception limit. The controller further identifies a trailer coupler within the trailer target area and outputs a steering signal to the vehicle to cause the vehicle to steer to align a hitch ball of the vehicle with the coupler during movement of the vehicle.
