Abstract

Une tête de détection magnétique à réluctance variable délivre un signal électrique (Uin) et on compare un front montant du signal électrique à un premier seuil (Th) pour passer d'un premier état (BO) à un deuxième état (B1), et on compare un front descendant à un deuxième seuil (Tb) inférieur au premier seuil (Th) pour passer du deuxième état (B1) au premier état (B0). Dans une étape de diagnostic, on modifie le premier (Th) ou le deuxième seuil (Tb) pour les rapprocher l'un de l'autre et on diagnostique une tête de détection magnétique défectueuse si le rapport cyclique du deuxième état (B1) est modifié pendant l'étape de diagnostic d'une valeur supérieure à un seuil de diagnostic prédéterminé par rapport à un niveau de référence. Circuit mettant en oeuvre le procédé.
