Title (EN) TRANSMISSION CONTROL DEVICE FOR TOROIDAL CONTINUOUSLY VARIABLE TRANSMISSION
(FR) DISPOSITIF DE COMMANDE DE TRANSMISSION POUR TRANSMISSION À VARIATION CONTINUE TOROÏDALE
(JA) トロイダル無段変速機の変速制御装置
Abstract:
(EN) A transmission control device for a toroidal continuously variable transmission, said control device comprising a gain setting device for adjusting a closed-loop control gain for calculating a target value for a roller position in accordance with a change in the rotation speed of a disc, in a first rotation speed range and in a second rotation speed range higher than the first rotation speed range. The gain setting device changes the gain in the first rotation speed range so as to reduce the sensitivity of the closed-loop control in conjunction with an increase in the rotation speed, and changes the gain in the second rotation speed range such that the rate of reduction of the sensitivity of the closed-loop control in conjunction with an increase in the rotation speed is less than in the first rotation speed range.
(FR) L'invention concerne un dispositif de commande de transmission pour une transmission à variation continue toroïdale, ledit dispositif de commande comprenant un dispositif de réglage de gain permettant d'adapter un gain de commande en boucle fermée pour calculer une valeur cible d'une position de rouleau en fonction d'un changement de la vitesse de rotation d'un disque, dans une première plage de vitesse de rotation et dans une seconde plage de vitesse de rotation supérieure à la première plage de vitesse de rotation. Le dispositif de réglage de gain modifie le gain dans la première plage de vitesse de rotation de façon à réduire la sensibilité de la commande en boucle fermée conjointement avec une augmentation de la vitesse de rotation, et modifie le gain dans la seconde plage de vitesse de rotation de telle sorte que le taux de réduction de la sensibilité de la commande en boucle fermée conjointement avec une augmentation de la vitesse de rotation est inférieur à celui de la première plage de vitesse de rotation.
(JA) トロイダル無段変速機の変速制御装置は、第1回転速度域と前記第1回転速度域よりも速い第2回転速度域とにおいて、ローラ位置の目標値を算出する閉ループ制御のゲインをディスクの回転速度の変化に応じて調整するゲイン設定器を備える。前記ゲイン設定器は、前記第1回転速度域では、前記回転速度の増加に伴って前記閉ループ制御の感度が低下するように前記ゲインを変化させ、前記第2回転速度域では、前記回転速度の増加に伴う前記閉ループ制御の感度の低下率が前記第1回転速度域よりも小さくなるように前記ゲインを変化させる。
