Abstract

Des systèmes de pile à combustible pour véhicules sont des ensembles complexes, qui sont commandés par des circuits à commande en boucle fermée ou ouverte, de telle sorte que l'énergie électrique nécessaire pour un fonctionnement de déplacement est fournie. En plus de l'actionnement pour un fonctionnement normal, d'autres stratégies de commande sont connues, pour permettre une commande en boucle fermée ou ouverte dans des cas spéciaux en dehors du fonctionnement normal, tel que, par exemple dans le cas d'une dégradation du système de pile à combustible ou si le véhicule a un accident. L'invention concerne un dispositif de sécurité 1 pour un véhicule 1 actionné par un système de pile à combustible 2, au moins quatre niveaux de sécurité de véhicule I-IV avec des schémas de réponse pouvant être activés.
