Title
(EN) A METHOD FOR CONTROLLING VEHICLES REPEATING A CYCLE
(FR) PROCÉDÉ DE COMMANDE DE VÉHICULES RÉPÉTANT UN CYCLE
Abstract
(EN)
The invention relates to method for controlling a plurality of vehicles which are repeating a cycle of driving along a route, which has at least one single vehicle area (SLTA1,.., SLTAm, SP, TP). The method comprises: - determining speed profiles for the vehicles, -creating a set of different starting times (t11, t21) for the vehicles, from a starting position (SP) of the cycle, - simulating vehicle movements through the cycle, with the speed profiles, and the created set of starting times (t11, t21), - repeating, a plurality of times, the steps of creating a set of starting times, and simulating vehicle movements, wherein the created set of starting times are different from one repetition to another, - selecting, for controlling the vehicles, from the sets of starting times created by the repetition of the step of creating a set of starting times, a set of starting times (t12, t22) for which the simulation shows that there is a minimum time overlap (to21) of vehicles at any of the at least one single vehicle area, and - controlling the vehicles according to the speed profiles and the selected set of starting times.

La présente invention concerne un procédé de commande d'une pluralité de véhicules qui répètent un cycle de conduite le long d'un itinéraire, qui présente au moins une zone de véhicule unique (SLTA1,..., SLTAm, SP, TP). Le procédé comprend les étapes consistant à : - déterminer des profils de vitesse pour les véhicules, - créer un ensemble de différents temps de démarrage (t11, t21) pour les véhicules, à partir d'une position de départ (SP) du cycle, - simuler des mouvements de véhicule à travers le cycle, avec les profils de vitesse, et l'ensemble créé de temps de démarrage (t11, t21), - répéter, une pluralité de fois, les étapes consistant à créer un ensemble de temps de démarrage, et simuler des mouvements de véhicule, l'ensemble créé de temps de démarrage étant différent d'une répétition à une autre, - sélectionner, pour commander les véhicules, à partir des ensembles de temps de démarrage créés par la répétition de l'étape de création d'un ensemble de temps de démarrage, un ensemble de temps de démarrage (t12, t22) pour lesquels la simulation montre qu'il existe un chevauchement dans le temps minimal (to21) de véhicules à l'une quelconque de la ou des zones de véhicule unique, et - commander les véhicules en fonction des profils de vitesse et de l'ensemble sélectionné de temps de démarrage.
