Abstract

II s'agit ici de déterminer la position d'une pièce tournante munie d'une cible de forme globalement circulaire associée à un capteur. La cible comporte au moins une dent et une encoche. Un bord sépare à chaque fois une dent d'une encoche.La cible ne présente pas une forme symétrique par rapport à l'un de ses diamètres.Les étapes suivantes sont mises en oeuvre :a) mesure du temps s'écoulant entre le passage de deux bords successifs,b) mémorisation du temps mesuré,c) répétition des étapes a) et b) n fois,d) calcul d'un coefficient à partir des n temps mémorisés précédemment,e) comparaison du coefficient déterminé par le calcul avec des coefficients théoriques prédéterminés,f) détermination de la position angulaire de la pièce tournante en fonction du coefficient théorique trouvé qui correspond au coefficient calculé.
