要約
(EN)
Provided are a belt‑based, continuously-variable transmission control device and a control method with which belt slippage can be prevented by not allowing the input torque to a belt‑based, continuously-variable transmission mechanism to become excessive relative to belt clamping force when normal control is resumed from belt slippage control. The device is equipped with a primary pulley (42), a secondary pulley (43), and a belt (44), and the transmission gear ratio produced by the pulley wrap ratio of the belt (44) is controlled by controlling a primary hydraulic pressure and a secondary hydraulic pressure. The belt‑based, continuously-variable transmission mechanism (4) is provided with a normal control means (Step S1) that performs normal control to effect an actual secondary hydraulic pressure that assures a belt clamping force based on the operating state, a belt slippage control means (step S3) that performs belt slippage control that reduces the actual secondary hydraulic pressure more than during the normal control, and a normal control resumption control means (step S5) that restricts the rate at which the input torque changes in the direction of increase of the input torque applied to the belt‑based, continuously-variable transmission mechanism (4) for a prescribed period after normal control is resumed from belt slippage control.

La présente invention concerne un dispositif de commande de transmission à variation continue basé sur une courroie et un procédé de commande avec lesquels un patinage de la courroie peut être évité en ne laissant pas le couple d'entrée d'un mécanisme de transmission à variation continue basé sur une courroie dépasser une force de serrage de courroie lorsqu'une commande normale est reprise après une commande de patinage de la courroie. Le dispositif est équipé d'une poulie principale (42), d'une poulie auxiliaire (43) et d'une courroie (44), et le rapport de transmission produit par le rapport d'enveloppement de poulie de la courroie (44) est commandé grâce à la commande d'une pression hydraulique principale et d'une pression hydraulique auxiliaire. Le mécanisme de transmission à variation continue basé sur une courroie (4) est doté d'un moyen de commande normale (étape S1) qui réalise une commande normale pour effectuer une pression hydraulique auxiliaire réelle qui assure une force de serrage de courroie sur la base de l'état de fonctionnement, d'un moyen de commande de patinage de la courroie (étape S3) qui réalise une commande de patinage de la courroie qui réduit la pression hydraulique auxiliaire réelle de façon plus importante que lors d'une commande normale, et d'un moyen de commande de reprise de la commande normale (étape S5) qui limite la vitesse à laquelle le couple d'entrée change dans la direction d'augmentation du couple d'entrée appliqué audit mécanisme (4) pendant une période prescrite après la reprise de la commande normale à partir de la commande de patinage de la courroie.

 ベルトスリップ制御から通常制御へ復帰させる際、ベルト式無段変速機構への入力トルクがベルトクランプ力に対して過大になることを抑制することで、ベルト滑りの発生を防止することができるベルト式無段変速機の制御装置と制御方法を提供する。プライマリプーリ(42)と、セカンダリプーリ(43)と、ベルト(44)を有し、プライマリ油圧とセカンダリ油圧を制御することにより、ベルト(44)のプーリ巻き付け径の比による変速比を制御する。このベルト式無段変速機構(4)において、運転状態に基づき、ベルトクランプ力を確保する実セカンダリ油圧を得る通常制御を行う通常制御手段(ステップS1)と、通常制御時よりも実セカンダリ油圧を低減させるベルトスリップ制御を行うベルトスリップ制御手段(ステップS3)と、ベルトスリップ制御から通常制御に復帰するとき、ベルト式無段変速機構(4)への入力トルクが増加方向に変化する入力トルク変化速度の制限を、復帰開始からの所定期間行う通常制御復帰制御手段(ステップS5)と、を備えた。
