  • Publication number: 20050046147
    Abstract: A trailer hitch alignment system provides a system that can be utilized with different trailers without requiring modification of the trailers or requiring minor modifications that require less than a minute or so to effect. In a preferred embodiment, the present invention provides two acoustic transceivers for directing acoustic signals towards and receiving reflected acoustic signals from a downwardly extending hitch assembly for a gooseneck trailer whereby this unique feature of the gooseneck trailer is utilized as a signal reflector. A timer is utilized to time the transmitted/reflected signals to determine at least two distances for determining a relative position of the downwardly extending hitch. A readout gives the driver ongoing feedback for aligning the gooseneck downwardly extending hitch with the hitch ball.
