(EN) CONTROL DEVICE FOR AUTOMATIC TRANSMISSION
(FR) DISPOSITIF DE COMMANDE POUR BOÎTE DE VITESSES AUTOMATIQUE
(JA) 自動変速機の制御装置
要約
(EN) Provided is a control device for an automatic transmission with which drive force responsiveness can be improved while suppressing the occurrence of shift shock. The ECU is configured so as to calculate a target shift time on the basis of input torque input to the automatic transmission when shifting to a target gear ratio two or more gear ratios away from the current gear ratio. When the target shift time is equal to or greater than a prescribed value, the ECU switches to an intermediate gear ratio between the current gear ratio and the target gear ratio, and when the target shift time is less than the prescribed value, the ECU switches directly to the target gear ratio.
(FR) L'invention concerne un dispositif de commande pour boîte de vitesses automatique au moyen duquel la réactivité d'une force d'entraînement peut être améliorée tout en supprimant la survenue d'un choc de changement de vitesse. L'ECU est configurée de manière à calculer un temps de changement de vitesse cible sur la base du couple d'entrée entré dans la transmission automatique lors d'un changement de vitesse vers un rapport de vitesse cible à deux rapports de vitesse ou plus au-delà du rapport de vitesse actuel. Lorsque le temps de changement de vitesse cible est supérieur ou égal à une valeur prescrite, l'ECU commute vers un rapport de vitesse intermédiaire entre le rapport de vitesse actuel et le rapport de vitesse cible, et lorsque le temps de changement de vitesse cible est inférieur à la valeur prescrite, l'ECU commute directement vers le rapport de vitesse cible.
(JA) 変速ショックの発生を抑制しながら、駆動力の応答性を向上させることが可能な自動変速機の制御装置を提供する。ECUは、現在の変速段から2段以上離れた目標変速段に変速される場合に、自動変速機に入力される入力トルクに基づいて目標変速時間を算出するように構成されている。そして、ECUは、目標変速時間が所定値以上の場合に、現在の変速段と目標変速段との間の中間変速段に切り替えるとともに、目標変速時間が所定値未満の場合に、目標変速段に直接切り替えるように構成されている。
