Title (EN) TRANSMISSION OIL PRESSURE CONTROL DEVICE AND CONTROL METHOD FOR CONTINUOUSLY VARIABLE TRANSMISSION
(FR) DISPOSITIF DE COMMANDE DE PRESSION D'HUILE DE TRANSMISSION ET PROCÉDÉ DE COMMANDE POUR TRANSMISSION À VARIATION CONTINUE
(JA) 無段変速機の変速油圧制御装置及び制御方法
Abstract:
(EN) A variator (4) has: a primary pulley (42); a secondary pulley (43); and a pulley belt (44) that is hung and suspended on both the pulleys (42), (43), wherein the transmission gear ratio is controlled by changing a pulley width by means of transmission oil pressure that is adjusted on the basis of discharge pressure from an oil pump (70). In this engine vehicle, when the target transmission gear ratio of the variator (4) is determined during traveling, primary pressure (Pri) and secondary pressure (Psec) adjusted according to the target transmission gear ratio are respectively supplied to the primary pulley (42) and the secondary pulley (43). When the pulley rotational speed reaches to a level at which the transmission gear ratio of the variator (4) does not change even if the secondary pressure (Psec) is reduced, control for reducing the secondary pressure (Psec) is started.
(FR) Variateur (4) comportant : une poulie primaire (42) ; une poulie secondaire (43) ; et une courroie (44) de poulie qui est accrochée et suspendue sur les deux poulies (42), (43), le rapport de transmission étant commandé par le changement d'une largeur de poulie au moyen d'une pression d'huile de transmission qui est ajustée sur la base d'une pression de refoulement provenant d'une pompe à huile (70). Dans ce véhicule à moteur, lorsque le rapport de transmission cible du variateur (4) est déterminé pendant le déplacement, une pression primaire (Pri) et une pression secondaire (Psec) réglées en fonction du rapport de transmission cible sont respectivement apportées à la poulie primaire (42) et à la poulie secondaire (43). Lorsque la vitesse de rotation de poulie atteint un niveau auquel le rapport de transmission du variateur (4) ne change pas même si la pression secondaire (Psec) est réduite, une commande pour réduire la pression secondaire (Psec) démarre.
(JA) バリエータ(4)は、プライマリプーリ(42)と、セカンダリプーリ(43)と、両プーリ(42),(43)に掛け渡されるプーリベルト(44)と、を有し、オイルポンプ(70)からの吐出圧に基づいて調圧された変速油圧によりプーリ幅が変更されることで変速比が制御される。このエンジン車において、走行中、バリエータ(4)の目標変速比が決まると、目標変速比に応じて調圧されたプライマリ圧(Pri)とセカンダリ圧(Psec)を、プライマリプーリ(42)とセカンダリプーリ(43)にそれぞれ供給する。セカンダリ圧(Psec)を低下させてもバリエータ(4)の変速比が変化しないプーリ回転速度になると、セカンダリ圧(Psec)を低下させる制御を開始する。
