Abstract
(EN)
A method of performing diagnostics in a hierarchical diagnostics electrical architecture of a vehicle, the vehicle comprising a plurality of on-board computing devices for hosting the hierarchical diagnostics electrical architecture. The hierarchical diagnostics electrical architecture comprising: a component diagnostic layer having a plurality of electronic control units each comprising a diagnostics server module; and at least one supervisory diagnostic layer. The method comprising: receiving into the diagnostics server modules sensor output data from one or more on-board vehicle sensors; performing, by the diagnostics server modules, one or more diagnostic tasks based on the received sensor output data to generate one or more component-level diagnostic notifications; receiving into the at least one supervisory layer the component-level diagnostic notifications from each of a group of the plurality of electronic control units; and aggregating in the at least one supervisory layer the received component-level diagnostic notifications to generate a supervisory-level diagnostic notification.

Procédé de réalisation de diagnostics dans une architecture électrique de diagnostic hiérarchique d'un véhicule, le véhicule comprenant une pluralité de dispositifs informatiques embarqués pour héberger l'architecture électrique de diagnostic hiérarchique. L'architecture électrique de diagnostic hiérarchique comprend : une couche de diagnostic de composant ayant une pluralité d'unités de commande électronique comprenant chacune un module de serveur de diagnostic ; et au moins une couche de diagnostic de supervision. Le procédé consiste à : recevoir dans le serveur de diagnostic des données de sortie de capteur provenant d'un ou plusieurs capteurs embarqués de véhicule ; la réalisation, par les modules de serveur de diagnostic, d'une ou de plusieurs tâches de diagnostic sur la base des données de sortie de capteur reçues pour générer une ou plusieurs notifications de diagnostic de niveau de composant ; recevoir dans la ou les couches de supervision les notifications de diagnostic de niveau de composant en provenance de chacun d'un groupe de la pluralité d'unités de commande électronique ; et agréger dans la ou les couches de supervision des notifications de diagnostic de niveau de composant reçues pour générer une notification de diagnostic de niveau de supervision.
