Abstract
Systems and methods for aligning a towing vehicle trailer hitch with the tongue of a trailer/towed vehicle are provided that enable a driver to know when the towing vehicle trailer hitch is close enough to the trailer tongue such that the two can be coupled. A trailer hitch includes a tow bar having a free end configured to be coupled to a trailer tongue. An alignment system includes at least one energy emitter secured to the vehicle that emits energy in the direction of the trailer tongue, and at least two sensors secured to the vehicle in spaced-apart relationship. The energy emitter(s) and sensors may be secured to the trailer or trailer hitch.
