Abstract

L'invention concerne un procédé destiné à déterminer une valeur de localisation (M) indiquant la position d'un véhicule sur rails sur un parcours. Selon ce procédé, des points de référence dont les positions respectives sont connues, sont relevés au niveau du véhicule sur rails par création de signaux de points de référence (Sreset), et la valeur de localisation est créée sur la base du dernier signal de point de référence (Sreset), et d'une valeur de parcours (S) indiquant le trajet parcouru par le véhicule sur rails à partir du dernier point de référence relevé, cette valeur de parcours (S) étant additionnée à une valeur de position (ML) prédéfinie indiquant la position de ce dernier point de référence. Pour une mise en oeuvre simple et économique d'un tel procédé, on prévoit d'intégrer des postes d'arrêt du véhicule sur rails en tant que points de référence pour la détermination de la valeur de localisation (M). Au cours de ces postes d'arrêt, au moins une porte du véhicule sur rails est ouverte afin de créer les signaux de points de référence (Sreset) sur la base de signaux de capteurs de porte (Stür = Sporte), créés par au moins un capteur de porte (15) disposé sur le véhicule sur rails.
