Abstract: A method for autonomously parking a vehicle-trailer system is provided. The method includes receiving sensor system data from a sensor system supported by the vehicle. The sensor system data includes images of surroundings along a driving path of the vehicle-trailer system. The method includes determining a local map based on the sensor system data. The local map includes surroundings along the driving path. The method includes receiving a user selection of an image location within the images. The image location representing a position in the local map associated with a selected location within the surroundings. The method includes determining a parking path from a current location of the vehicle-trailer system to the position based on the local map and instructing a drive system to execute an autonomous parking behavior causing the vehicle-trailer system to autonomously drive along the parking path and autonomously park in the selected location.

Abstract: 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.
