Method and system for determining an articulation angle of a vehicle combination

A system 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 system comprises an image obtaining device which is provided on the first vehicle section and configured to obtain images of the second vehicle section during use, wherein the system comprises a processing unit which is configured to:

• obtain a first image of the second vehicle section by the image obtaining device;
• mirror the first image, thereby obtaining a second mirrored image;
• and
• determine 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.
