Abstract

L’invention concerne un procédé et un système de détermination d’un état de fonctionnement d’un ou plusieurs capteurs (131 à 133 ; 141, 142) reliés à un premier calculateur (13 ; 14) d’un système embarqué (100). A cet effet, des codes d’erreur sont détectés. Chaque code d’erreur détecté est comparé à une liste de codes d’erreurs, la liste étant pas exemple comprise dans une table mettant en correspondance chaque code d’erreur avec un unique capteur relié au premier calculateur. A partir des codes d’erreurs détectés et de la comparaison de ces codes avec la liste de codes d’erreur, il est possible de déterminer quels capteurs du premier calculateur sont dans un état de défaut de fonctionnement et quels capteurs sont dans un état de fonctionnement sans défaut. Une information d’identification de chaque capteur du premier calculateur est transmise, par exemple à un deuxième calculateur (11), avec l’état de fonctionnement associé. Figure pour l’abrégé : Figure 1The invention relates to a method and a system for determining an operating state of one or more sensors (131 to 133; 141, 142) connected to a first computer (13; 14) of an on-board system (100). . For this purpose, error codes are detected. Each error code detected is compared with a list of error codes, the list not being included, for example, in a table mapping each error code with a single sensor connected to the first computer. From the error codes detected and the comparison of these codes with the list of error codes, it is possible to determine which sensors of the first computer are in a malfunction state and which sensors are in a fault state. fault-free operation. Information identifying each sensor of the first computer is transmitted, for example to a second computer (11), with the associated operating status. Figure for the abstract: Figure 1
