Problems solved by technology
[0003] However, coupling a towing vehicle to a towed vehicle can be difficult to perform, primarily because the operator of the towing vehicle does not have a direct line of sight to the ball and hitch of the tether system
Alignment and positioning inaccuracies can occur even when direct line of sight may exist or other aids may be available, such as electronic sensing systems that send information to the operator of the towing vehicle about the distance between the ball and hitch

Embodiment Construction
[0010] The following description is only exemplary in nature and is not intended to limit the present disclosure, application or use.
[0011] now refer to figure 1 , a system for assisting in docking or coupling a first vehicle with a second vehicle is indicated generally at 10 . The docking assist system 10 is used with a towing vehicle 12 , which is an example of a first vehicle, and a towed vehicle 14 , which is an example of a second vehicle. It should be appreciated that the towing vehicle 12 may take a variety of forms, such as in the form of a car, truck, tractor, or other off-road vehicle, without departing from the scope of the present invention. Similarly, it should be appreciated that the towed vehicle 14 may take various forms, such as in the form of a trailer, camper, or other motor vehicle. The towing vehicle 12 generally includes a tongue 16 extending from a rear portion 18 thereof. A vehicle coupling member or ball 20 is fixedly secured to a bumper or other...

An automatic docking system for docking a towing vehicle with a towed vehicle includes a sensing device, a controller, an automatic steering system, an automatic braking system, and a plurality of targets. The sensing device detects the plurality of targets located on a hitch of the towed vehicle. The controller determines the location of the towing vehicle relative to the towed vehicle based on the detection of the plurality of targets. The controller automatically steers the towing vehicle towards the towed vehicle to assist in the docking of the towing vehicle to the towed vehicle. The controller engages the automatic braking system to slow or stop the towing vehicle as required.
Description
technical field [0001] The present invention generally relates to docking assist systems for vehicles. More particularly, the present invention relates to systems for guiding a towing vehicle toward a towed vehicle. Background technique [0002] Many vehicles, including cars, trucks, tractors and other off-road vehicles, are capable of towing vehicles. Examples of towed vehicles include trailers, campers, farm equipment, construction equipment, or other motor vehicles. Typically, the towing vehicle is coupled to the trailer being towed by a tether system. A tether system typically includes two coupling components, such as a ball and a link, that can be removably coupled together. The coupling components are coupled together by aligning the coupling components of the towing vehicle with the coupling components of the towed vehicle and moving either or both of the towing vehicle or the towed vehicle together. [0003] However, coupling a towing vehicle to a towed vehicle c...
