Abstract
A data processor determines a position solution or selects a position solution from a first position solution and a second position solution based on a comparison between the turning radius at a hitch point, R, and the tongue length, where R=Vp/(α'−δ′), where Vis a velocity at the hitch point, α′ is the vehicle yaw rate, and δ′ is the change in a vehicle slip angle. A trailer position of a trailer is estimated in accordance with a position solution (e.g., determined or selected position solution) based on the determined vehicle heading, the hitch length, and the tongue length.
