Abstract

La présente invention concerne un procédé pour détecter la direction du mouvement d'un moteur, notamment d'un moteur électrique qui fait partie d'un système d'actionnement de transmission et sert à la sélection et/ou à la commutation, au moins un signal du moteur étant détecté. Le procédé de l'invention se caractérise en ce que la direction de mouvement du moteur est déterminée grâce au signal détecté en se basant sur la direction du courant d'alimentation. L'invention a également pour objet un moteur, notamment un moteur de commutation ou de sélection qui fait partie d'un système d'actionnement de transmission et qui permet la mise en oeuvre du procédé, au moins un dispositif servant à déterminer la direction de mouvement du moteur.
