System and method for determining a hitch angle based on an input from a sensor and a kinematic model of a vehicle and a trailer, and for controlling the vehicle based on the hitch angle
First Claim
1. A system comprising:
- an estimated hitch angle module that estimates a hitch angle, wherein the hitch angle is an angle between a longitudinal axis of a vehicle and a longitudinal axis of a trailer that is attached to the vehicle;
a measured hitch angle module that determines a measured hitch angle based on an input from a sensor;
a corrected hitch angle module that determines a corrected hitch angle based on the estimated hitch angle and the measured hitch angle; and
at least one of;
a driver assist module that controls a user interface device to assist a driver of the vehicle based on the corrected hitch angle; and
an actuator control module that controls an actuator of at least one of the vehicle and the trailer based on the corrected hitch angle.

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.
