Abstract:
(EN) The purpose of the present invention is to enhance the belt durability of a belt-type continuously variable transmission while still ensuring drive performance in a region in which a required drive force value is small when the vehicle starts moving. In a drive system from a drive source to drive wheels (5, 5), an engine (1), a first clutch (2), a motor generator (3), a second clutch (4), and a belt-type continuously variable transmission CVT are mounted. The drive modes of the drive system include an EV mode via disengagement of the first clutch (2) and an HEV mode via engagement of the first clutch (2). In this method for controlling an FF hybrid vehicle, a WSC mode, in which a transmission torque to the drive wheels (5, 5) is made equivalent to a target drive force by placing the second clutch (4) into a slip engagement state, is selected as the drive mode when the vehicle starts moving. When a drive force value required by a driver is equal to or less than a threshold while the WSC mode is selected, the belt-type continuously variable transmission CVT is fixed to the Lowest transmission gear ratio. When the drive force value required by the driver exceeds the threshold, the fixing to the Lowest transmission gear ratio of the belt-type continuously variable transmission CVT is released.
(FR) L'objectif de la présente invention est d'améliorer la durabilité de courroie d'une transmission à variation continue de type à courroie tout en garantissant les performances d'entraînement dans une région dans laquelle une valeur de force d'entraînement requise est petite lorsque le véhicule commence à se déplacer. Dans un système d'entraînement à partir d'une source d'entraînement vers des roues motrices (5, 5), un moteur (1), un premier embrayage (2), un moteur-générateur (3), un second embrayage (4) et une transmission à variation continue (CVT) de type à courroie sont montés. Les modes d'entraînement du système d'entraînement comprennent un mode EV par l'intermédiaire d'un désengagement du premier embrayage (2) et d'un mode HEV par mise en prise du premier embrayage (2). Dans ce procédé de commande d'un véhicule hybride FF, un mode WSC, dans lequel un couple de transmission destiné aux roues motrices (5, 5) est rendu équivalent à une force d'entraînement cible par placement du second embrayage (4) dans un état de mise en prise de patinage, est sélectionné comme mode d'entraînement lorsque le véhicule commence à se déplacer. Lorsqu'une valeur de force d'entraînement requise par un conducteur est inférieure ou égale à un seuil tandis que le mode WSC est sélectionné, la transmission à variation continue (CVT) de type à courroie est fixée au rapport de vitesse de transmission le plus bas. Lorsque la valeur de force d'entraînement requise par le conducteur dépasse le seuil, la fixation au rapport de vitesse de transmission le plus bas de la transmission à variation continue (CVT) de type à courroie est libérée.
(JA) 発進時、駆動力要求値が低い領域での運転性能を確保しつつ、ベルト式無段変速機のベルト耐久性向上を図ること。 駆動源から駆動輪(5,5)までの駆動系に、エンジン(1)と第1クラッチ(2)とモータジェネレータ(3)と第2クラッチ(4)とベルト式無段変速機CVTとを搭載する。駆動系による運転モードとして、第1クラッチ(2)の解放によるEVモードと、第1クラッチ(2)の締結によるHEVモードと、を有する。このFFハイブリッド車両の制御方法において、発進時、運転モードとして、第2クラッチ(4)を滑り締結状態とすることで駆動輪(5,5)への伝達トルクを目標駆動力相当とするWSCモードを選択する。WSCモードの選択中、ドライバの駆動力要求値が閾値以下であるとベルト式無段変速機CVTを最Low変速比に固定する。ドライバの駆動力要求値が閾値を超えるとベルト式無段変速機CVTの最Low変速比の固定を解除する。
