Abstract
A trailer backup assist system, according to one embodiment, includes a steering input device for inputting a desired backing path of a trailer. The trailer backup assist system also includes a first sensor that senses a hitch angle between a vehicle and the trailer. Further, the trailer backup assist system includes a second sensor that senses a proximity of an object in a perimeter field of at least one of the vehicle and the trailer. A controller of the trailer backup assist system generates an available set of backing paths for the trailer based on the proximity of the object and the hitch angle. The available set of backing paths does not include backing paths that cross a space occupied by the object or that cause a jackknife condition between the vehicle and the trailer.
