  • Patent number: 7057498
    Abstract: A visual aid for assisting a driver backing a towing vehicle to a towed vehicle. The visual/audible display consists of a ten-segment bar graph, with various colors, an indicator lamp and a beeper. A sensor is placed on the ball hitch of the towing vehicle and an emitter is placed on the hitch of the towed vehicle. The sensor receives a signal from the emitter and processes it to be sent to the display. The display indicates the relative positions of the two vehicles. It also provides visual and audible signals to indicate approach of the devices and the proper alignment for hitching. Attachment is temporary and universal, enabling use with any hitch configuration. Data transmission is wireless eliminating the need for cables between the units. All units have enclosed batteries so no external power connection is required.
