First Claim
Patent Images
1. A system for initializing hitch angle detection, comprising:
- an imaging device configured to capture images of a trailer connected to a vehicle;
a controller configured to select between a plurality of hitch angle detection routines based on at least one of a current driving condition and an availability of a template image of the trailer;
wherein if the template image is available, the controller selects a first hitch angle detection routine that comprises matching the template image to a search image to determine a hitch angle between the vehicle and the trailer;
wherein if the template image is unavailable and the vehicle and trailer are moving in a straight direction, the controller processes images captured by the imaging device to derive the template image and selects the first hitch angle detection routine.

13. A method of initializing hitch angle detection, comprising the steps of:
-
using an imaging device to capture images of a trailer connected to a vehicle; and providing a controller configured to select between a first, second, and third hitch angle detection routine based on at least one of a current driving condition and an availability of a template image of the trailer; wherein if the template image is available, the controller selects the first hitch angle detection routine that comprises matching the template image to a search image to determine a hitch angle between the vehicle and the trailer; and wherein if the template image is unavailable and the vehicle and trailer are moving in a straight direction, the controller processes images captured by the imaging device to derive the template image and selects the first hitch angle detection routine. - View Dependent Claims (14, 15)
