Abstract
A system and a method are provided for estimating an actual hitch angle between a vehicle and a trailer. A hitch sensor on the vehicle continuously senses a measured hitch angle and a steering sensor continuously senses a steering angle of steered wheels of the vehicle. A controller determines an offset between the measured hitch angle and the actual hitch angle when the measured hitch angle and the steering angle are substantially constant while the vehicle and trailer are reversing.
