TRAILER ANGLE DETECTION TARGET FADE WARNING
First Claim
1. A method of detecting degradation of an optical target on a trailer, the method comprising:
- generating a first set of data corresponding to optical characteristics of an optical target on a trailer;
generating a second set of data corresponding to optical characteristics of an optical target on a trailer after generating the first set of data;
providing an alert if differences between the first and second sets of data exceed predefined criteria indicating that the target has degraded or is likely to degrade within a predefined period of time.

Abstract
A method of detecting degradation of an optical target on a trailer. The method includes generating a first set of data corresponding to optical characteristics of an optical target on a trailer. The method also includes generating a second set of data corresponding to optical characteristics of an optical target on a trailer after generating the first set of data. The method further includes providing an alert if differences between the first and second sets of data exceed predefined criteria indicating that the target has degraded. The predefined criteria may comprise fading or other suitable optical characteristics of the target.

12. A method of detecting fading of a target on a trailer, comprising:
-
generating first and second images of a target on a trailer at chronologically spaced apart times utilizing a vehicle-mounted camera; generating first and second sets of image histogram data corresponding to the first and second images; and generating an alert if differences between the first and second sets of image histogram data satisfy predefined criteria indicating that the target has faded. - View Dependent Claims (13, 14, 15, 16, 17)

18. A system for detecting degradation of a target on a trailer, the system comprising:
-
a target defining a plurality of optical properties, wherein the target is configured to be mounted to a trailer; a camera configured to generate image data of the target to provide input to a trailer backup assist system; a controller configured to utilize image data from the camera generated at chronologically spaced first and second times to determine if at least a selected one of the optical properties of the target has degraded according to predefined criteria; and
wherein;the system is configured to generate an alert if the selected one of the optical properties of the target has degraded according to the predefined criteria. - View Dependent Claims (19, 20)
