Abstract

Procédé de détermination d’une résistance d’isolement du réseau haute-tension d’un véhicule électrique ou hybride, où on fournit une source de tension continue commandable reliée à la caisse et à une unique première borne d’une batterie haute-tension du véhicule, une première résistance étant connectée en série avec ladite source entre l’unique première borne et la caisse et une seconde résistance étant connectée en série entre la première résistance et ladite source, on applique des valeurs successives de consigne de tension entre la caisse et l’unique première borne, on acquiert un signal de mesure de la tension aux bornes de ladite seconde résistance pour chaque valeur de consigne, on effectue un filtrage adaptatif de ce signal et une estimation, de façon récursive, d’un vecteur des coefficients de la fonction de transfert du filtre, délivrant une mise à jour des coefficients de filtrage, la résistance d’isolement étant déterminée à partir de ladite estimation. Figure à publier avec l’abrégé : Fig. 1
