Abstract

L'invention concerne un procédé de correction de l'angle de site d'un projecteur d'un véhicule automobile comportant des moyens (12) pour élaborer un signal (S_ass) d'assiette du véhicule, des moyens (16) pour élaborer un signal (S_varacc) des variations d'accélération du véhicule, des moyens (14) d'élaboration d'un seuil variant (S_bruit), du type qui comporte :- une première étape (E1) de calcul d'un critère dynamique (C_dyn) à partir de la valeur du signal (S_varacc) des variation d'accélération et d'un seuil variant (S_bruit) ;- une deuxième étape (E2) au cours de laquelle on affecte à un coefficient de filtrage (K22) une valeur minimale (K22_min), une valeur maximale (K22_max) ou une valeur intermédiaire (K22_nom) selon la valeur du critère dynamique (C_dyn) ;- une troisième étape (E3) de filtrage du signal (S_ass) d'assiette en fonction du coefficient de filtrage (K22) ; et- une quatrième étape (E4) de correction de l'angle de site du projecteur en fonction du signal d'assiette filtré (S_ass_22).
