Abstract

L'invention concerne un procédé pour faire fonctionner un véhicule sur rails. Un premier (1) et un deuxième (2) véhicule sur rails se déplacent sur un rail (4) divisé en n blocs (40). Le procédé comprend les étapes consistant à : A) fournir une première information qui indique que le premier véhicule sur rails traverse, à un premier moment (t1), une limite (41) de bloc entre un bloc i et un bloc i+1 ; B) fournir une deuxième information qui indique que le deuxième véhicule sur rails traverse, à un deuxième moment (t2), une limite de bloc entre un bloc j et un bloc j+1 ; C) déterminer une troisième information qui indique si un bloc entre le bloc i+1 et le bloc j est occupé par un autre véhicule sur rails avant et/ou entre les deux moments ; D) valider un premier état de fonctionnement pour le premier véhicule sur rails en fonction de la troisième information si la troisième information indique qu'aucun bloc n'est occupé, le premier état de fonctionnement étant un déplacement à un intervalle variable.
