TRACK GUIDANCE METHOD, TRACK GUIDANCE SYSTEM, AND VEHICLE

The invention relates to a track guidance method, to a track guidance system, and to a vehicle for a track guidance operation along a track on a roadway, said track and roadway having different colors. The method has the following steps which are carried out one after the other in time: in a first step, the track and the roadway are illuminated with a first color spectrum, said first color spectrum having the color of the track, and the intensity of the reflected light is measured on the basis of a position transverse to the direction of extension of the track; in a second step, the track and the roadway are illuminated with a second color spectrum, and the intensity of the reflected light is measured on the basis of the position transverse to the direction of extension of the track, wherein the first color spectrum is different from the second color spectrum, in particular the intensity component of the color of the track is lower in the second color spectrum than in the first color spectrum, in particular the second color spectrum does not have the color of the track; and in a third step, the absolute difference between the intensity measured in the first step and the intensity measured in the second step is calculated as a function of the position transverse to the direction of extension of the track.
