Abstract

L'invention concerne un système et un procédé pour tester une chaussée automatisée coopérative à application V2X et une voiture connectée, le procédé pouvant, afin de tester un système de chaussée automatisée coopérative et des véhicules de voiture connectés roulant sur des chaussées correspondantes, concevoir un scénario de test, puis générer des données virtuelles en conséquence ; collecter des données d'entrée/de sortie/internes pour chaque système constituant le système de chaussée automatisée coopérative ; et effectuer une analyse et une évaluation des fonctions et des performances du système de chaussée automatisée coopérative et des véhicules de test. Le système selon l'invention comprend : un dispositif de collecte d'informations pour collecter des données à partir d'objets de test ; un client d'analyse pour fournir une interface utilisateur (UI) pour générer des règles de test et des scénarios de test ; et un serveur de test complet pour générer des règles et des scénarios de test sélectionnés par l'intermédiaire de l'UI du client d'analyse, effectuer un test complet V2X au moyen des données provenant du dispositif de collecte d'informations selon les scénarios de test contenant les règles de test générées, et analyser des résultats de test.
