1. A vehicular trailer hitching assist system, said vehicular trailer hitching assist system comprising:
a rear backup camera disposed at a rear portion of a vehicle equipped with said vehicular trailer hitching assist system;
wherein said rear backup camera that is disposed at the rear portion of the equipped vehicle views at least a portion of a vehicle bumper of the equipped vehicle;
wherein said rear backup camera comprises a Complementary Metal Oxide Semiconductor (CMOS) imaging array;
said rear backup camera having a field of view at least rearward of the equipped vehicle;
said rear backup camera capturing image data during operation of the equipped vehicle;
a control disposed in the equipped vehicle;
said control comprising circuitry;
where said control receives a signal indicative of selection by a driver of the equipped vehicle of a transmission gear of the equipped vehicle;
wherein said control connects to a vehicle network of the equipped vehicle;
a display device of the equipped vehicle, said display device comprising a video display screen operable to display video images for viewing by the driver of the equipped vehicle during operation of the equipped vehicle;
wherein said control controls display of video images at said video display screen;
wherein, responsive to the driver initiating a hitching maneuver event by engaging reverse gear of the equipped vehicle, rear backup video images derived from image data captured by said rear backup camera are displayed at said video display screen;
wherein at least one overlay overlays the displayed rear backup video images;
wherein the at least one overlay aids in guiding connection of a trailer hitch of the equipped vehicle to a trailer tongue of a trailer;
wherein, during the hitching maneuver event, and while the driver of the equipped vehicle is maneuvering the equipped vehicle back and forth to align the trailer hitch of the equipped vehicle with the trailer tongue of the trailer, (a) said video display screen displays rear backup video images derived from image data captured by said rear backup camera that are overlaid by the at least one overlay during backward movement of the equipped vehicle with reverse gear selected by the driver and (b) said video display screen continues to display rear backup video images derived from image data captured by said rear backup camera that are overlaid by the at least one overlay during short-term forward movement of the equipped vehicle in drive gear that lasts until a threshold period of time elapses;
wherein the threshold period of time is not longer than 10 seconds; and
wherein the continued display at said video display screen of rear backup video images derived from image data captured by said rear backup camera that are overlaid by the at least one overlay is ceased by said control upon elapse of the threshold period of time.
