1. A method for determining an articulation angle of a vehicle combination comprising a first vehicle section, such as a truck, and a second vehicle section, such as a trailer or dolly unit, which are connected via a first articulation joint, wherein the first vehicle section comprises an image obtaining device which is configured to obtain images of the second vehicle section during use, the method comprising:
obtaining a first image of the second vehicle section by the image obtaining device;
mirroring the first image, thereby obtaining a second mirrored image; and
determining the articulation angle between the first and the second vehicle sections based on a required level of relative rotation of the first image and the second mirrored image until the first image and the second mirrored image match each other.
