Title (EN) CONTROL DEVICE FOR AN AUTOMATIC TRANSMISSION
(FR) DISPOSITIF DE COMMANDE DE TRANSMISSION AUTOMATIQUE
(JA) 自動変速機の制御装置
Abstract:
(EN) Between the completion of gear shifting (for example, from third to fourth gear) and a first prescribed time T1, when it is determined that the gear ratio is at one of the gear ratios of the various gear shift levels, and the original gear ratio (4TH) and the computed gear ratio (5TH) differ, it is determined that clutch C-3 which should have been released has failed to engage. Meanwhile, when it is determined that between the completion of gear shifting and a first prescribed time Ta, the gear ratio has not achieved the gear ratio of any of the gear change levels, failure determination is suspended to prevent the incorrect determination that clutch C-2 has failed to disengage (is neutral). When it is subsequently determined that some gear ratio has been achieved over a second prescribed time Tb, the suspension of failure determination is cancelled and it is determined that clutch C-3 has failed to engage. An incorrect determination of failure after gear shifting is prevented, and failures can be quickly and accurately determined.
(FR) Si dans un premier intervalle de temps donné (T1) décompté à partir de la fin d'un changement de vitesse (par exemple, un changement de vitesse 3 - 4), le dispositif détermine que le nouveau rapport de vitesse correspond à l'un quelconque des rapports de vitesse des différents niveaux de changement de vitesse et si, en outre, le rapport de vitesse d'origine (4 TH) et le rapport de vitesse résultant du changement opéré (5 TH) sont différents, le dispositif conclut à un échec d'engagement de l'embrayage (C - 3) qui devait être libéré. Par ailleurs, lorsque dans un premier intervalle de temps donné (Ta) décompté à partir de la fin du changement de vitesse, il détermine que le rapport de vitesse ne correspond à aucune mise en œuvre effective de l'un des rapports de vitesse des différents niveaux de changement de vitesse, il suspend le diagnostic d'échec et empêche que soit donné un verdict erroné selon lequel il y aurait un échec de libération (point mort) de l'embrayage (C-2). Ensuite, si, durant un second intervalle de temps donné (Tb), il détermine que l'un des rapports de vitesse est devenu effectif, il supprime la suspension du diagnostic d'échec, et conclut à un échec d'engagement de l'embrayage (C-3). Grâce à ce dispositif, on peut éviter les diagnostics d'échec erronés après un changement de vitesse, et obtenir des diagnostics rapides et justes.
(JA)  変速(例えば3-4変速)終了時から第1の所定時間T1の間にギヤ比が各変速段のギヤ比の何れかとなったことが判定され、かつ本来のギヤ比(4TH)と演算されたギヤ比(5TH)とが異なる場合、解放されるはずのクラッチC-3が係合フェールであることを判定する。一方、変速終了時から第1の所定時間Taの間にギヤ比が何れの変速段のギヤ比も成立していないことを判定した際は、フェール判定を中断し、クラッチC-2が解放フェール(ニュートラル)であると誤判定してしまうことを防止する。その後、第2の所定時間Tbに亘って何れかのギヤ比が成立したことを判定した際は、フェール判定の中断を解除し、クラッチC-3の係合フェールを判定する。これにより、変速後のフェール判定の誤判定の防止が図られ、フェール判定を迅速にかつ正確に行うことが可能となる。
