L\u2019utilisation de la simulation pour la d\u00e9monstration de la s\u00e9curit\u00e9 du v\u00e9hicule autonome est une alternative incontournable aux essais de validation physiques. La principale difficult\u00e9 est d\u2019assurer un comportement s\u00fbr au v\u00e9hicule dans la multitude de situations auxquelles il est confront\u00e9. Le projet 3SA s\u2019int\u00e9resse aux trois grands aspects de la s\u00e9curisation du v\u00e9hicule autonome (hors cybers\u00e9curit\u00e9):<\/p>\n

\u2022 le dysfonctionnel des syst\u00e8mes et inter-syst\u00e8mes li\u00e9s notamment aux bugs logiciels ou aux pannes mat\u00e9rielles,<\/p>\n

\u2022 le fonctionnel s\u00fbr (ou SOTIF, Safety Of The Intended Functionality) centr\u00e9 sur les d\u00e9cisions erron\u00e9es li\u00e9es notamment \u00e0 une mauvaise interpr\u00e9tation de l\u2019environnement par le v\u00e9hicule,<\/p>\n

\u2022 et les m\u00e9susages potentiellement pr\u00e9visibles du conducteur visant \u00e0 identifier et emp\u00eacher les mauvaises utilisations du syst\u00e8me.<\/p>\n

Dans la continuit\u00e9 du projet SVA, les activit\u00e9s suivantes seront poursuivies et approfondies :<\/p>\n

– Mod\u00e9lisation des capteurs : ce sujet, techniquement complexe, est incontournable car les capteurs sont \u00e0 l\u2019origine d\u2019erreurs d\u2019interpr\u00e9tation de l\u2019environnement par le v\u00e9hicule. Pour pouvoir tester le comportement du v\u00e9hicule autonome par simulation dans un environnement d\u00e9gradant le fonctionnement des capteurs (pluie, brouillard, luminosit\u00e9, etc.), il est indispensable de conna\u00eetre les effets perturbants de l\u2019environnement sur les donn\u00e9es fournies par les capteurs et d\u2019int\u00e9grer ces effets dans les mod\u00e8les de capteurs. La caract\u00e9risation et de la mod\u00e9lisation des cam\u00e9ras et radars seront poursuivies et compl\u00e9t\u00e9es par l\u2019\u00e9tude des lidars et de la navigation.<\/p>\n

– Etude des m\u00e9thodes et outils de simulation des syst\u00e8mes de conduite autonome : plusieurs approches continueront d\u2019\u00eatre explor\u00e9es afin de valider le comportement d\u2019un v\u00e9hicule dans un environnement num\u00e9rique et d\u2019auditer des algorithmes de d\u00e9cisions. Dans ce cadre, diff\u00e9rents niveaux d\u2019abstraction de la mod\u00e9lisation seront utilis\u00e9s pour adapter la repr\u00e9sentativit\u00e9 de la simulation \u00e0 l\u2019exhaustivit\u00e9 des tests en fonction du besoin. Il s\u2019agira notamment de r\u00e9duire la complexit\u00e9 de la mise en oeuvre des mod\u00e8les, de d\u00e9velopper des m\u00e9thodes de post-traitement des r\u00e9sultats et d\u2019optimiser l\u2019exploitation des mod\u00e8les pour r\u00e9duire les temps de calcul.<\/p>\n

\u00ab R\u00e9unissant les principaux constructeurs et \u00e9quipementiers fran\u00e7ais, le projet SVA \u00e9tait tr\u00e8s ambitieux. Il a notamment permis de mettre en \u00e9vidence les limites des m\u00e9thodologies existantes et de proposer des m\u00e9thodes et outils de mod\u00e9lisation pour aider \u00e0 la conception et \u00e0 la validation des v\u00e9hicules autonomes. D\u2019autres r\u00e9sultats embl\u00e9matiques ont marqu\u00e9 ce projet : le partage d\u2019une vision commune du probl\u00e8me pos\u00e9 par la sp\u00e9cificit\u00e9 de la s\u00e9curisation du v\u00e9hicule autonome, la constitution d\u2019une biblioth\u00e8que de sc\u00e9narios et la r\u00e9alisation d\u2019une plateforme de simulation du v\u00e9hicule et de son environnement. Le projet 3SA se focalisera sur les diff\u00e9rentes approches par simulation pour prendre en compte le fonctionnel s\u00fbr (l\u2019identification correcte par le v\u00e9hicule de l\u2019environnement complexe dans lequel il \u00e9volue) sur la recherche de crit\u00e8res de validation, d\u2019estimation du taux de couverture des tests, etc. L\u2019approche et les comp\u00e9tences d\u00e9velopp\u00e9es contribueront \u00e0 d\u00e9fendre la position de la France sur la sc\u00e8ne internationale \u00bb, explique Jean Van Frank, chef de projet 3SA.<\/p>\n
