A method for visual trailer tracking of vehicle-trailer angle estimation, including: (a) camera receiving images, each most recently received image being identified as a current image, replacing a previously identified current image; (b) during a driving maneuver, extracting visual features from the current image, calculating a trailer angle from the current image, and storing the current image as a reference image, the trailer angle as a trailer angle reference and the extracted visual features as visual reference features; and (c) matching the visual features from the current image with the visual reference features. When a number of matches is below a threshold, repeating operation (c) to update the reference image, the trailer angle reference and the visual reference features. The method includes calculating a trailer angle between a trailer representation in the current image and a trailer representation in the reference image based in part upon the trailer angle reference.
