Abstract

L’invention concerne un procédé de mise à jour d’un logiciel d’un véhicule, comportant des mémoires d’exécution (ME), de sauvegarde (MS) et de contrôle (MC) comportant des étapes de : - Emission d’une requête commandant une écriture en mémoire de contrôle (MC) d’au moins un bloc de logiciel mis à jour (B’,C’), - Emission d’une requête commandant une vérification dudit au moins un bloc de logiciel mis à jour (B’,C’) stocké en mémoire de contrôle (MC), - Emission d’une requête commandant la copie depuis la mémoire d’exécution (ME) vers la mémoire de sauvegarde (MS) de la pluralité de blocs (A, B, C), - Emission d’une requête commandant la copie depuis la mémoire de contrôle (MC) vers la mémoire d’exécution (ME) dudit au moins un bloc de logiciel mis à jour (B’,C’), - Emission d’une requête commandant une vérification de l’intégrité des blocs (A,B’,C’) de logiciel de la mémoire d’exécution (ME). Figure pour l’abrégé : Figure 5The invention relates to a method for updating vehicle software, comprising execution (ME), backup (MS) and control (MC) memories comprising the steps of: - Issuing a request controlling a writing in the control memory (MC) of at least one updated software block (B ', C'), - Sending of a request controlling a verification of said at least one updated software block ( B ', C') stored in control memory (MC), - Sending of a request commanding the copy from the execution memory (ME) to the backup memory (MS) of the plurality of blocks (A, B , C), - Sending of a request commanding the copy from the control memory (MC) to the execution memory (ME) of said at least one updated software block (B ', C'), - Sending a request controlling a check of the integrity of the software blocks (A, B ', C') of the execution memory (ME).
