Abstract

L'invention concerne un système de commande d'un véhicule automobile pour un véhicule automobile équipé d'un entraînement hybride. Des premiers appareils de commande, à savoir au moins un appareil de commande de moteur (2) associé à un moteur à combustion interne de l'entraînement hybride, un appareil de commande de transmission (7) associé à une transmission, et un appareil de commande de gestion hybride (6), sont raccordés à un premier bus de données (1), et des deuxièmes appareils de commande, à savoir au moins l'appareil de commande de gestion hybride (6) et d'autres appareils de commande (9, 10, 11, 12) d'une partie de chaîne cinématique à moteur électrique, sont raccordés à un deuxième bus de données (8). Seul un des appareils de commande raccordés au deuxième buse de données (8) tient, de manière centralisée, des données d'application à la disposition de l'appareil de commande de gestion hybride (6) et de tous les autres appareils de commande de la partie de chaîne cinématique à moteur électrique, en vue de la fourniture de données dépendantes d'une application, alors que les autres appareils de commande de la partie de chaîne cinématique à moteur électrique ne contiennent eux-mêmes que des données de programme indépendantes d'une application sans fourniture de données par le biais de cet appareil de commande.
