Patent abstract
A vision sensor mounted above a hitch ball attached to a vehicle detects a colored magnet mounted on a trailer hitch and transmits the visual signal to a processor mounted within the vehicle operated by a power source such as the vehicle's 12 volt D.C. battery. The processor assimilates the sensor's signal and indicates the location of the trailer hitch on a display screen mounted on the dashboard of the vehicle. As the vehicle driver backs his vehicle to place the trailer hitch signal on the ball signal, the actual ball on the vehicle ends up under the trailer hitch.
