Abstract

L’invention concerne un dispositif de localisation de nœuds secondaires d’un véhicule, comprenant un nœud principal et n nœuds secondaires avec n=2 à N, N entier, reliés ensemble via au moins deux sous-réseaux, chaque sous-réseau comprenant m nœuds secondaires avec m=1 à M entier, caractérisé en ce que chaque sous-réseau comprend un nœud secondaire terminal situé à l’extrémité de chaque sous-réseau,(a) - le nœud principal est configuré pour être connecté à au moins un des deux sous-réseaux et comprend une unité de contrôle électronique principale configurée pour lors d’une phase d’apprentissage : - activer l’alimentation d’un des au moins deux sous-réseaux et désactiver l’alimentation des autres sous-réseaux, - recevoir des messages de présence des nœuds secondaires dudit sous-réseau activé, lesdits message de présence comprenant un identifiant unique associé à chaque nœud secondaire,- identifier ledit nœud secondaire terminal dudit sous-réseau activé grâce à un champ de son identifiant unique,- localiser ledit nœud secondaire terminal dans ledit sous-réseau activé grâce à l’architecture dudit sous-réseau activé, - si n = 2 ou 3, en fonction de l’architecture dudit réseau véhicule, déterminer la localisation des autres nœuds secondaires dudit réseau véhicule,- si n> 3 :- envoyer une commande audit nœud secondaire terminal pour qu’il effectue des mesures de distances entre lui-même et les autres nœuds secondaires d’un des au moins deux sous-réseaux,- recevoir lesdites distances et les comparer entre elles,- en fonction de l’architecture dudit sous-réseau activé et de ladite comparaison, déterminer la localisation desdits autres nœuds secondaires.The invention relates to a device for locating secondary nodes of a vehicle, comprising: a main node and n secondary nodes with n=2 to N, integer N, connected together via at least two subnetworks, each subnetwork comprising m secondary nodes with m=1 to M integer, characterized in that each subnetwork comprises a terminal secondary node located at the end of each subnetwork, (a) - the main node is configured to be connected to at least one of the two sub-networks and comprises a main electronic control unit configured to during a learning phase: - activate the power supply to one of the at least two sub-networks and deactivate the power supply to the other sub-networks, - receive presence messages from the secondary nodes of said activated subnetwork, said presence messages comprising a unique identifier associated with each secondary node, - identify said terminal secondary node of said activated subnetwork using a field of its unique identifier, - locate said terminal secondary node in said activated subnetwork thanks to the architecture of said activated subnetwork, - if n = 2 or 3, depending on the architecture of said vehicle network, determine the location of the other secondary nodes of said vehicle network , - if n> 3: - send a command to said secondary terminal node so that it carries out distance measurements between itself and the other secondary nodes of one of the at least two subnetworks, - receive said distances and the compare them, - depending on the architecture of said activated subnetwork and said comparison, determine the location of said other secondary nodes.
