Abstract

L'invention concerne un procédé destiné au contrôle de systèmes de chaînes cinématiques pour des véhicules sur banc d'essai, selon lequel des états de charge réels correspondant à des manoeuvres de conduite réelles sont appliqués sur la chaîne cinématique, pilotés par un système d'automatisation de banc d'essai, au moins une grandeur de mesure étant captée sur la chaîne cinématique. L'invention vise à étalonner les systèmes et à contrôler leur bon fonctionnement sans se référer à des véhicules ou des systèmes connus et sans avoir à faire des essais sur route impliquant des dangers pour le véhicule sous test et pour les utilisateurs. À cet effet, les états de charge sont déterminés en temps réel, sur la base de manoeuvres et/ou de résultats, au moyen d'au moins un système de simulation coopérant avec le système d'automatisation de banc d'essai, la ou les grandeurs de mesure captées étant transmises en tant que grandeurs d'entrée au système de simulation.
