CALIBRATION SYSTEM FOR HYDRAULIC TRANSMISSION

A calibration system for calibrating a transmission adjusts a clutch fill pulse width and hold level current for an oncoming clutch via calibration shifts during operation of the associated machine, thus establishing the desired shift timing and duration. The pulse width is calibrated based on torqu...

Zusammenfassung:	A calibration system for calibrating a transmission adjusts a clutch fill pulse width and hold level current for an oncoming clutch via calibration shifts during operation of the associated machine, thus establishing the desired shift timing and duration. The pulse width is calibrated based on torque transfer characteristics of the clutch during a test shift, and the hold level current is calibrated based on the shift duration of a further test shift. Système d'étalonnage pour transmission permettant le réglage d'une largeur d'impulsion de remplissage et d'un courant de niveau de tenue pour un embrayage activé, à partir de décalages d'étalonnage qui interviennent durant le fonctionnement de la machine associée, ce qui établit la synchronisation et la durée de décalage souhaitées. On étalonne la largeur d'impulsion sur la base des caractéristiques de transfert de couple de l'embrayage durant un décalage d'essai, et le courant de niveau de tenue est étalonné sur la base de la durée de décalage d'un décalage d'essai supplémentaire.
