Abstract
A system according to the present disclosure includes an estimated hitch angle module, a measured hitch angle module, a corrected hitch angle module, and at least one of a driver assist module and an actuator control module. The estimated hitch angle module estimates a hitch angle, which is an angle between a longitudinal axis of a vehicle and a longitudinal axis of a trailer that is attached to the vehicle. The measured hitch angle module determines a measured hitch angle based on an input from a sensor. The corrected hitch angle module determines a corrected hitch angle based on the estimated and measured hitch angles. The driver assist module controls a user interface device to assist a driver of the vehicle based on the corrected hitch angle. The actuator control module controls an actuator of at least one of the vehicle and the trailer based on the corrected hitch angle.
