Abstract

Cette invention concerne un procédé et un dispositif pour traitement de données. Le procédé comprend : l'établissement d'une connexion de communication entre un dispositif de diagnostic et un véhicule, et l'acquisition de données de diagnostic du véhicule par l'intermédiaire d'au moins deux bus (S10); lorsqu'une instruction de demande de données transmise par un serveur est reçue, le filtrage des données de diagnostic sur la base de l'instruction de demande de données pour produire des données à transmettre (S20); et la transmission des données à transmettre au serveur (S30). Le procédé selon l'invention permet au dispositif de diagnostic d'acquérir simultanément des données de véhicule par l'intermédiaire de multiples bus, pendant le processus de transmission des données acquises au serveur, de filtrer les données de telle sorte que toutes les données qui ne sont pas requises par le serveur soient supprimées, seules les données requises par le serveur étant transmises au serveur, de sorte à réduire le volume de trafic de données requis par le dispositif de diagnostic lors du processus de transmission des données au serveur, et à réduire les coûts pour le dispositif de diagnostic lors du diagnostic du véhicule.
