Patent number: 11687081Abstract: A method for driving a tractor on a flatbed trailer. The method includes locating a starting position of the tractor, determining a final position for the tractor, and searching for a ramp attached to the flatbed trailer. A driving path is calculated to drive the tractor from the starting position, along the ramp, and to the final position. The tractor is autonomously operated to drive along the driving path. The method may periodically detect an intermediate position of the tractor and determining if the intermediate position is located on the driving path.
