Abstract

L'invention concerne un procédé pour faire fonctionner une station de base (1), consistant à mettre à disposition de cette dernière plusieurs trajets (3, 5, 7, 9) représentant un tronçon respectif pouvant être parcouru par un véhicule dans un environnement de la station de base (1). Il consiste également à mettre à disposition des données d'au moins un véhicule dans l'environnement de la station de base (1). Les données de véhicule comprennent une position actuelle et une direction actuelle du véhicule respectif. Le procédé consiste également à déterminer, en fonction des données de véhicule, un tronçon qui est parcouru actuellement par le véhicule respectif et qui est associé à un trajet actuel. Il consiste en outre à déterminer, en fonction des données de véhicule, un trajet consécutif au trajet actuel, représentant un tronçon qui a le plus de chance d'être parcouru par le véhicule respectif à la suite du trajet actuellement parcouru. Il consiste enfin à mettre à disposition du véhicule respectif, par l'intermédiaire de la station de base (1), le trajet suivant le trajet actuel. L'invention concerne en outre un dispositif de commande correspondant.
