Abstract
L'invention concerne un dispositif de réglage de pression de ligne pour transmission automatique. Selon l'invention, il comprend un circuit 7 pour obtenir un signal de pression de ligne voulue d'un signal de charge réellement mesurée du moteur obtenu par un capteur, un capteur 5 de pression de ligne pour produire un signal de pression de ligne réellement mesurée correspondant à la pression de ligne, un convertisseur 13 pour convertir le signal de pression de ligne voulue ou le signal de pression de ligne réellement mesurée en un signal de pression de ligne sur limite supérieure et un signal de pression de ligne sur limite inférieure et un circuit de décision 18 pour comparer les signaux de pression de ligne sur limites supérieure et inférieure au signal qui n'a pas été converti, et pour mesurer réellement le signal de pression de ligne et bien entraîner la vanne d'ajustement de pression hydraulique selon le résultat de la comparaison. L'invention s'applique notamment à l'industrie automobile.
