Summary:A method for ascertaining a relative angle between a first longitudinal axis of a towing vehicle and a second longitudinal axis of a vehicle that is mechanically coupled to the towing vehicle, including: detecting a light unit situated at the vehicle using a camera unit situated at the towing vehicle to obtain image information of the light unit; recognizing the light unit in the obtained image information, using an optical signal that is emitted by the detected light unit to obtain position information of the light unit, the position information representing a spatial position of the light unit in the image information relative to a defined reference point; ascertaining the relative angle between the first longitudinal axis of the towing vehicle and the second longitudinal axis of the vehicle, using the position information of the detected light unit; and emitting a signal as a function of the ascertained relative angle.
