SENSOR SYSTEM AND METHOD FOR MONITORING TRAILER HITCH ANGLE
First Claim
Patent Images
1. A sensor system for estimating a hitch angle of a trailer attached to a vehicle, comprising:
- a primary sensor having a camera monitoring a target on the trailer to determine a measured hitch angle;
a secondary sensor monitoring the trailer to determine an indicator of the hitch angle; and
a controller steering the vehicle to attain a selected hitch angle if the measured hitch angle correlates with the indicator.

Abstract
A sensor system and method for estimating a hitch angle of a trailer attached to a vehicle includes a primary sensor and a secondary sensor. The primary sensor has a camera that monitors a target on the trailer to determine a measured hitch angle. The secondary sensor monitors the trailer to determine an indicator of the hitch angle. The sensor system also includes a controller to steer the vehicle to attain a selected hitch angle when the measured hitch angle correlates with the indicator of the hitch angle.

10. A sensor system for monitoring a trailer attached to a vehicle, comprising:
-
a primary sensor on the vehicle measuring a first hitch angle between the vehicle and the trailer; a secondary sensor on the vehicle measuring a second hitch angle between the vehicle and the trailer; and a controller operating the vehicle in reverse based on the first hitch angle being within a tolerance range defined by the second hitch angle. - View Dependent Claims (11, 12, 13, 14, 15)
