Abstract

L'invention concerne un procédé permettant la détection côté véhicule de la position d'un véhicule ferroviaire (1) commandé par radio par l'intermédiaire de points d'accès côté voie. Le but de l'invention est de permettre l'acquisition précise de données de position, en particulier pour l'étalonnage de systèmes d'odométrie, à intervalles faibles et sensiblement réguliers. A cet effet, la position des points d'accès est détectée par capteur. Selon l'invention, le véhicule ferroviaire (1) comprend au moins une unité d'émission/réception (2), reliée à un dispositif de mesure et d'analyse, pour la détection des positions des points d'accès.
