Abstract

La présente invention a pour objet un procédé de calibration automatique d'un capteur (10) d'arbre à cames pour moteur de véhicule automobile, le dit capteur mesurant les variations de valeur de champ magnétique (B) et délivrant un signal électrique (Se) ayant un état haut (I), après le passage des valeurs du champ magnétique au dessus du seuil de commutation (S1) sur un front ascendant et un état bas (II) après le passage des valeurs du champ magnétique en dessous du seuil de commutation (S1) sur un front descendant, l'invention proposant que : • après le passage des valeurs du champ magnétique au dessus du seuil de commutation (S1), et la mesure d'une nouvelle valeur maximale (Bmax2), le signal électrique reste dans un état haut (I) tant que les valeurs du champ magnétique sont supérieures à un seuil d'hystérésis (SH), qui est fonction de l'amplitude du champ magnétique calculé avec la nouvelle valeur maximale mesurée, • après le passage des valeurs du champ magnétique en dessous du seuil d'hystérésis (SH), un nouveau seuil de commutation (S2) est calculé en fonction de la nouvelle valeur maximale.
