Patent ID: 10780893

Abstract:
A system and method for estimating the length of a trailer attached to a vehicle includes a processor and a sensor mounted to the vehicle and in communication with the processor. The sensor is configured to sense at least one target on the trailer and provide information to the processor regarding the location of the at least one target. The processor is configured to determine an estimate of the wheel based length (laa1) of the trailer by utilizing a wheel angle (α) of the vehicle, a hitch point (zk) of the vehicle, the first hitch angle (γ1), a wheel base (lza) of the vehicle, a distance (lzk) between the hitch point (zk) and a front axle of vehicle, and a lane radius (rza). The processor is configured to determine the length of a trailer attached to the vehicle by utilizing the wheel based length (laa1) of the trailer.
