Abstract
A system for determining an adhesion value between wheel and rail for a railway vehicle is described, comprising an optical information acquisition means arranged to acquire optical information from the rail, a database arranged to store the acquired optical information in at least a learning phase and to associate said information with a relevant real wheel-rail adhesion value measured at the moment of acquisition of the optical information, a control unit arranged to determine the current wheel-rail adhesion value on the basis of a comparison between current acquired optical information and the optical information previously stored in the database. The control unit determines that the current wheel-rail adhesion value associated with the current acquired optical information corresponds to the adhesion value associated with the optical information stored in the database having the highest degree of similarity with the current acquired optical information.
