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.

9. A method for aligning a vehicle with a gooseneck trailer, said gooseneck trailer having a downwardly extending hitch assembly for mating with a hitch ball mounted to said vehicle, said vehicle comprising a cab, a truck bed, and a bed box, said hitch ball being mounted within said bed box, said system comprising:
-
transmitting one or more acoustic signals in a direction of said downwardly extending hitch assembly;
receiving a first reflected signal from said downwardly extending hitch assembly;
receiving a second reflected signal from said downwardly extending hitch assembly;
determining a relative position between said downwardly extending hitch assembly and said hitch ball within said bed box from said steps of receiving said first reflected signal and said second reflected signal; and
monitoring changes in said relative position between said downwardly extending hitch assembly and said hitch ball within said bed box while adjusting a relative position of said vehicle with respect to said gooseneck trailer to thereby align said downwardly extending hitch assembly with said hitch ball within said bed box. - View Dependent Claims (10, 14)

15. A method for aligning a vehicle with a trailer, said trailer having a target element for mating with a hitch ball mounted to said vehicle, said system comprising:
-
transmitting one or more signals in a direction of said downwardly extending hitch assembly;
passively reflecting a first reflected signal from said target element to a first receiver;
passively reflecting a second reflected signal from said target element to a second receiver;
utilizing a timer to determine a relative position between said target element and said hitch ball from said first reflected signal and said second reflected signal; and
monitoring changes in said relative position between said target element and said hitch ball while adjusting a relative position of said vehicle with respect to said gooseneck trailer to thereby align said target element with said hitch ball - View Dependent Claims (16, 17, 19, 20)
