Method and system for monitoring placement of a target on a trailer
First Claim
1. A method of monitoring placement of a target on a trailer comprising:
- generating an image of a target placement zone on the trailer using a camera on a towing vehicle;
generating a target overlay on the image indicative of the target placement zone to assist with placing the target on the trailer;
processing the image with a controller to detect presence of a placed target within the target placement zone based on the generated target overlay; and
generating with the controller an external feedback alert during target placement confirming at least one of (i) the placed target is detected within the target placement zone and (ii) the placed target is not detected within the target placement zone.

Abstract
A vehicle trailer backup assist system and method includes a hitch angle detection apparatus and a target monitor controller. The target monitor controller processes images acquired of the trailer towed by a towing vehicle to assist with placement of a target on the trailer. The target monitor controller also monitors the target and provides feedback to the user as to proper positioning of the target on the trailer. A target move detection routine detects movement of a target by processing the pixels of the image to determine if a new trailer has been connected. Further, a trailer connection monitoring routine monitors for a changed trailer based on loss of the hitch angle or target for a predetermined time period.

12. A system for monitoring placement of a target on a trailer comprising:
-
a camera located on a towing vehicle and arranged to generate an image of a target placement zone on the trailer towed by the towing vehicle; an image processor generating a target overlay on the image indicative of the target placement zone to assist with placing the target on the trailer, processing the image to detect presence of a placed target located within the target placement zone based on the generated target overlay, and usable for determining a hitch angle of the trailer and generating a feedback alert signal during the target placement; and an exterior alert generating a feedback alert responsive to the feedback alert signal confirming at least one of (i) the placed target is detected within the target placement zone and (ii) the placed target is not detected within the target placement zone. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
