Abstract

La présente invention concerne un dispositif et un procédé pour enregistrer des données dans un véhicule automobile. Une carte mémoire, utilisée en tant que support d'information à grande capacité d'enregistrement, est montée sur le véhicule automobile et est introduite dans une interface côté véhicule automobile destinée à lire/décrire. Le véhicule automobile est pourvu d'un bus de données auquel l'interface et d'autres systèmes, composants et capteurs du véhicule automobile sont raccordés. Un dispositif de diagnostic d'erreur se trouvant à bord génère des codes d'erreur qui, avec d'autres données pertinentes issues de différents systèmes côté véhicule automobile, sont enregistrés sur la carte mémoire, constamment dans le sens de profils de charge permanents, et sont maintenus pendant la période d'utilisation complète. Les données enregistrées comprennent des éléments concernant le véhicule automobile et le support, des codes d'erreur concernant l'état des différents systèmes et composants du véhicule automobile, des paramètres de fonctionnement, des informations concernant la réparation et le service et, éventuellement, des éléments concernant les contrôles techniques obligatoires, des spécifications et des instructions d'utilisation. Ces données peuvent être exploitées de différentes façons pour améliorer le produit, adopter une bonne stratégie de réparation et déterminer le comportement en service de véhicules automobiles.
