Title
(EN) MODULAR NETWORK BASED KNOWLEDGE SHARING FOR MULTIPLE ENTITIES
(FR) PARTAGE DE CONNAISSANCES BASÉ SUR UN RÉSEAU MODULAIRE POUR DE MULTIPLES ENTITÉS
Abstract
(EN) A method for vehicle fault detection is provided. The method includes training (810), by a cloud module controlled by a processor device, an entity-shared modular and a shared modular connection controller. The entity- shared modular stores common knowledge for a transfer scope, and is formed from a set of sub- networks which are dynamically assembled for different target entities of a vehicle by the shared modular connection controller. The method further includes training (820), by an edge module controlled by another processor device, an entity-specific decoder and an entity-specific connection controller. The entity-specific decoder is for filtering entity- specific information from the common knowledge in the entity- shared modular by dynamically assembling the set of sub-networks in a manner decided by the entity specific connection controller.
(FR) L'invention concerne un procédé de détection de défaillance de véhicule. Le procédé consiste à former (810), par un module en nuage commandé par un dispositif de processeur, un dispositif modulaire partagé par des entités et un dispositif de commande de connexion modulaire partagée. Le dispositif modulaire partagé par des entités stocke des connaissances communes pour un cadre de transfert et est formé à partir d'un ensemble de sous-réseaux qui sont assemblés de manière dynamique pour différentes entités cibles d'un véhicule par le dispositif de commande de connexion modulaire partagée. Le procédé consiste en outre à former (820), par un module de bord commandé par un autre dispositif de processeur, un décodeur spécifique d'une entité et un dispositif de commande de connexion spécifique d'une entité. Le décodeur spécifique d'une entité est destiné à filtrer des informations spécifiques d'une entité à partir de connaissances communes dans le dispositif modulaire partagé par des entités par assemblage dynamique de l'ensemble de sous-réseaux d'une manière décidée par le dispositif de commande de connexion spécifique d'une entité.
