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.This involves determining the position of a rotating part provided with a target of generally circular shape associated with a sensor. The target has at least one tooth and one notch. Each time an edge separates a tooth from a notch The target does not have a symmetrical shape with respect to one of its diameters The following steps are implemented: a) measurement of the time elapsing between the passage of two successive edges, b) memorization of the measured time, c) repetition of steps a) and b) n times, d) calculation of a coefficient from the n times memorized previously, e) comparison of the coefficient determined by the calculation with predetermined theoretical coefficients, f) determining the angular position of the rotating part as a function of the theoretical coefficient found which corresponds to the calculated coefficient.
