Abstract

La présente invention concerne un procédé de préservation d'une intégrité d'une unité de contrôle électronique embarquée dans un véhicule automobile en cas de modifications non autorisées de la programmation. Le véhicule envoie (2) des données représentatives de la programmation de l'unité à un serveur (7) effectuant une comparaison des données envoyées avec les données spécifiques à l'unité mémorisées. Quand une modification des données envoyées par rapport aux données spécifiques est détectée, le serveur (7) envoie un statut d'intégrité non conforme en retour au véhicule, le véhicule informant le conducteur d'une réception d'un statut d'intégrité non conforme et l'unité mettant en œuvre une planification d'au moins un dysfonctionnement temporaire, lors d'un prochain fonctionnement du véhicule, simulant une défaillance du véhicule progressive incitant le conducteur à amener son véhicule à un centre de réparation.The present invention relates to a method for preserving the integrity of an on-board electronic control unit in a motor vehicle in the event of unauthorized modifications to the programming. The vehicle sends (2) data representative of the programming of the unit to a server (7) performing a comparison of the data sent with the data specific to the stored unit. When a change in the sent data relative to the specific data is detected, the server (7) sends a non-compliant integrity status back to the vehicle, the vehicle notifying the driver of a receipt of a non-compliant integrity status. and the unit implementing a schedule of at least one temporary malfunction, during a subsequent operation of the vehicle, simulating a progressive vehicle failure prompting the driver to take his vehicle to a repair center.
