Abstract

Il est proposé un procédé de traitement d'un signal primaire produit par un capteur de rotation d'une cible tournante du type à niveaux de tension. Le signal primaire comprend des impulsions ayant, pour une vitesse de rotation de la cible donnée, un premier niveau de tension positif lorsque la cible tourne dans un premier sens de rotation déterminé ou un second niveau de tension positif, différent dudit premier niveau de tension, lorsque la cible tourne dans un second sens de rotation inverse dudit premier sens de rotation On génère un premier signal secondaire (COMP1 ) par comparaison du signal primaire à un premier seuil de tension (TH1 ) déterminé, compris entre le premier niveau de tension et le second niveau de tension. On génère un second signal secondaire (COMP2) par comparaison du signal primaire à un second seuil de tension (TH2) déterminé, compris entre le second niveau de tension et la tension nulle. On introduit intentionnellement un retard déterminé (τ) dans le second signal secondaire par rapport au premier signal secondaire. Puis on compare à un seuil de temps déterminé, la durée entre un front actif du second signal secondaire et le dernier front actif du premier signal secondaire précédant ledit front actif du second signal secondaire, pour en déduire le sens de rotation de la cible.
