Abstract

LE SIGNAL DE SORTIE D'UN TRANSDUCTEUR 28 EST ENVOYE A UN CIRCUIT ELECTRIQUE 29 POUR LE TRANSMETTRE A UN CIRCUIT DE COMMANDE DE L'ALIMENTATION EN COMBUSTIBLE D'UN MOTEUR A COMBUSTION INTERNE. POUR CONTROLER LE SIGNAL DE SORTIE DU TRANSDUCTEUR, ON PRELEVE CELUI DU CIRCUIT ELECTRIQUE 29 AU MOYEN D'UN CIRCUIT QUI ENTRE EN ACTION LORSQUE LE DEPLACEMENT D'UN ELEMENT 16 ASSOCIE AU TRANSDUCTEUR ATTEINT UNE VALEUR CONNUE. LE SIGNAL SORTANT DU CIRCUIT DE PRELEVEMENT EST ENVOYE A UN COMPARATEUR 31 QUI RECOIT UN SIGNALDE REFERENCE. LE SIGNAL REPRESENTANT LA DIFFERENCE EVENTUELLEMENT EST TRANSMIS A UN CIRCUIT CORRECTEUR 33 QUI CALCULE UNE NOUVELLE VALEUR DE GAIN POUR UN AMPLIFICATEUR A GAIN VARIABLE MONTE DANS LE CIRCUIT ELECTRIQUE 29. LA VALEUR DE GAIN EST MEMORISEE DANS UN CIRCUIT DE MAINTIEN 34 ET ENVOYEE A L'AMPLIFICATEUR JUSQU'A CE QU'UN NOUVEAU REGLAGE SOIT NECESSAIRE.
