Abstract
A method for determining a trailer angle between a tow vehicle and a trailer attached to the tow vehicle includes receiving images from a camera positioned on a rear portion of the tow vehicle with a data processing hardware device, determining visual features from the images, tracking the visual features while the tow vehicle and trailer are moving and calculating, at the data processing hardware, the trailer angle based on the visual features. The trailer angle is then transmitted from the data processing hardware to one or more vehicle systems.
