Abstract
Systems and methods for estimating a length of at least a portion of a trailer that is carried by a tractor. The tractor has a fifth wheel coupling that is configured to be connected to a kingpin of the trailer. The height of the fifth wheel coupling is adjustable by adjustment of an angle of a boom that carries the fifth wheel coupling. The angle of the boom is determined by a sensor. The angle of the trailer is determined by a sensor. The length of at least a portion of the trailer is calculated based on the boom length, the determined boom angle, and the determined trailer angle.
