Abstract
A system and method of calculating a heading angle for a trailer that is being backed by a vehicle. A trailer backup assist control module, in communication with a hitch angle detecting apparatus, receives a hitch angle and determines displacement of left and right vehicle wheels using information supplied by vehicle wheel speed sensors while the vehicle is backing the trailer. A vehicle heading angle is determined using left and right wheel displacement information and a known vehicle track width. A trailer heading angle is then calculated using the vehicle heading angle and the hitch angle.
