Abstract

Procédé de contrôle de l'engagement et du dégagement d'un doigt de frein de parking (la) de transmission, responsable du blocage ou du déblocage d'un arbre de la transmission, sous la commande d'un plateau rotatif de sélection (9) motorisé qui bute contre le carter (3) de la transmission aux deux extrémités de sa course et s'immobilise entre celles-ci dans une première position fonctionnelle d'engagement (Park) ou dans une deuxième position fonctionnelle de dégagement (non Park) du doigt de parking lorsque le moteur d'entraînement du plateau cesse d'exercer un couple sur celui-ci, caractérisé en ce que les déplacements angulaires du plateau entre ses positions de butée sont mesurés et incrémentés dans une unité de calcul de la transmission, pour déterminer si la position fonctionnelle Park ou non Park du plateau atteinte après chaque coupure du moteur d'entraînement, correspond à l'instruction de commande donnée au moteur par la transmission.
