METHOD AND SYSTEM FOR ESTIMATING A TRAILER POSITION OF A TRAILER ASSOCIATED WITH A VEHICLE Abstract of the Disclosure 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/(a'- 5'), where Vp is a velocity at the hitch point, a' is the vehicle yaw rate, and 6' 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.
