Abstract

L'invention concerne un système, en particulier un système de trafic ferroviaire à petite distance, et un procédé pour la détection du trajet côté véhicule pour un tel système. Le système comporte des véhicules qui se déplacent le long d'un parcours (7), sur lequel est disposé à demeure au moins un repérage de position (1) côté voie, qui comporte un dispositif émetteur et qui transmet son identification aux véhicules, en ce qu'il diffuse un signal avec l'identification par l'antenne du dispositif émetteur, dont la caractéristique de diffusion (2) comporte un lobe principal (3), les véhicules appréhendant le passage du repérage de position (1). Pour diminuer les erreurs au niveau de la détermination de position côté véhicule, on propose que la position (O) du dispositif émetteur et ainsi le repérage de position (1) soit la position centrale entre les deux positions (11, 12) auxquelles le signal du lobe principal (3) dépasse au passage une valeur de seuil (8) prédéfinie, d'abord par valeur supérieure et ensuite de nouveau par valeur inférieure.
