Title (EN) CONTINUOUSLY VARIABLE TRANSMISSION AND HYDRAULIC PRESSURE CONTROL METHOD THEREFOR
(FR) TRANSMISSION À VARIATION CONTINUE ET PROCÉDÉ DE COMMANDE DE PRESSION HYDRAULIQUE
(JA) 無段変速機及びその油圧制御方法
Abstract:
(EN) In the present invention, on the basis of a transmission gear ratio, a target primary pressure and a target secondary pressure are set. At least, in a crosspoint region that is a region in which an absolute value of a deviation obtained by subtracting the target primary pressure from the target secondary pressure becomes smaller than a prescribed deviation, a target line pressure that is the target value of a line pressure is set to be a value in which an offset amount that is a positive value is added to the greater from between the target primary pressure and the target secondary pressure. The primary pressure, secondary pressure and line pressure are controlled to be the target primary pressure, target secondary pressure and target line pressure respectively.
(FR) Dans la présente invention, une pression primaire cible et une pression secondaire cible sont fixées sur la base d'un rapport de transmission. Au moins dans une région de point de croisement, qui est une région dans laquelle une valeur absolue d'un écart obtenu en soustrayant la pression primaire cible de la pression secondaire cible, devient inférieure à un écart prescrit, une pression de ligne cible, qui est la valeur cible d'une pression de ligne, est réglée à une valeur à laquelle une quantité de décalage, qui est une valeur positive, est ajoutée à la plus grande des pressions, parmi la pression primaire cible et la pression secondaire cible. La pression primaire, la pression secondaire et la pression de ligne sont commandées de façon à être respectivement la pression primaire cible, la pression secondaire cible et la pression de ligne cible.
(JA)  変速比に基づき目標プライマリ圧と目標セカンダリ圧とを設定し、少なくとも、目標セカンダリ圧から目標プライマリ圧を引いて得られる偏差の絶対値が所定偏差よりも小さくなる領域であるクロスポイント領域において、ライン圧の目標値である目標ライン圧を、目標プライマリ圧及び目標セカンダリ圧のうちより高い方に正の値であるオフセット量を加えた値に設定し、プライマリ圧、セカンダリ圧及びライン圧を、それぞれ目標プライマリ圧、目標セカンダリ圧及び目標ライン圧に制御する。
