Abstract

L'invention concerne un procédé de montage d'un système de capteur dans un véhicule comprenant un châssis, le châssis se trouvant dans une position définie pendant le montage et le système de capteur étant fixé directement ou indirectement au châssis. Le procédé selon l'invention est caractérisé en ce que le système de capteur comprend un ou plusieurs capteurs d'accélération (1) à trois directions de mesure linéairement indépendantes et présente une unité de contrôle électronique (3) comprenant un mode d'étalonnage de capteur. Après fixation du système de capteur, le ou les capteurs d'accélération détectent l'accélération de la pesanteur et l'unité de contrôle électronique calcule en mode d'étalonnage de capteur un ou plusieurs paramètres de positionnement relatif à partir d'au moins la direction acquise de l'accélération (g) de la pesanteur et les sauvegarde. Ces paramètres comprennent au moins une information sur le positionnement relatif entre le système de capteur et le châssis du véhicule.
