Abstract

L'invention concerne notamment un système de bus dans un véhicule automobile, avec au moins un premier bus, qui présente des appareils de commande en tant qu'abonnés de bus. Pour obtenir un système de bus plus flexible en termes de diagnostic d'erreurs, on installe selon l'invention au moins un dispositif de passerelle avec un dispositif de contrôle d'accès en tant qu'accès, depuis l'extérieur du véhicule, au moins au premier bus et aux appareils de commande qui lui sont raccordés. Le dispositif de passerelle est commuté dans un mode de diagnostic dans lequel, contrairement à un mode de fonctionnement du dispositif de passerelle, qui est activé pendant le fonctionnement normal du véhicule automobile, au moins une première information de bus est acheminée à au moins un premier appareil de commande des appareils de commande sous le contrôle du dispositif de passerelle. La première information de bus correspond au moins sensiblement à une information de bus qui est également reçue par le premier appareil de commande pendant un fonctionnement normal du véhicule automobile.
