The invention relates to a method for determining a relative angle between a first longitudinal axis (70) of a towing vehicle (12) and a second longitudinal axis (72) of a vehicle (14) that is mechanically coupled to the towing vehicle (12). The method includes the following steps: capturing a light unit (26, 28, 30, 32) arranged on the vehicle (14) by means of a camera unit (22, 24) arranged on the towing vehicle (12), in order to obtain image information of the light unit (26, 28, 30, 32); identifying the light unit (26, 28, 30, 32) in the obtained image data (48, 50) using an optical signal(40, 42, 44, 46) emitted by the captured light unit (26, 28, 30, 32), in order to obtain position information of the light unit (26, 28, 30, 32), wherein the position information represents a spatialposition (52', 58') of the light unit (26, 28, 30, 32) in the image data (48, 50) relative to a defined reference point (60, 66); determining a relative angle between the first longitudinal axis (70)of the towing vehicle (12) and the second longitudinal axis (72) of the vehicle (14) using the position information of the captured light unit (26, 28, 30, 32); and emitting a signal according to thedetermined relative angle.

    本发明涉及一种用于求取牵引车(12)的第一纵轴线(70)和与所述牵引车(12)机械耦合的车辆(14)的第二纵轴线(72)之间的相对角度的方法,所述方法具有以下步骤:‑借助布置在所述牵引车(12)上的摄像机单元(22、24)感测布置在所述车辆(14)上的光单元(26、28、30、32),以便获得所述光单元(26、28、30、32)的图像信息;‑在使用由被感测的所述光单元(26、28、30、32)发出的光信号(40、42、44、46)在获得的图像信息(48、50)中识别所述光单元(26、28、30、32),以便获得所述光单元(26、28、30、32)的位置信息,其中,所述位置信息代表所述光单元(26、28、30、32)在所述图像信息(48、0)中相对于限定的参考点(60、66)的空间位置(52'、58');‑在使用被感测的所述光单元(26、28、30、32)的位置信息的情况下求取所述牵引车(12)的所述第一纵轴线(70)和所述车辆(14)的所述第二纵轴线(72)之间的相对角度;和‑根据求出的相对角度发出信号。
