Title (EN) HYDRAULIC CONTROL APPARATUS AND HYDRAULIC CONTROL METHOD OF VEHICULAR AUTOMATIC TRANSMISSION
(FR) APPAREIL DE COMMANDE HYDRAULIQUE ET PROCEDE DE COMMANDE HYDRAULIQUE DE TRANSMISSION AUTOMATIQUE DE VEHICULE
Abstract:
(EN) A hydraulic control apparatus of a vehicular automatic transmission has a plurality of hydraulic friction engagement devices that are selectively engaged and released to establish a plurality of forward speed change stages of different speed change ratios. The forward speed change stages are achieved through engagement of predetermined friction engagement devices, of the plurality of friction engagement devices. If it is determined that a predetermined speed change stage corresponding to a predetermined Shift output is not established, the hydraulic control apparatus identifies a hydraulic friction engagement device having a bad engagement that is a cause of the non-cstabJishment of the predetermined speed change stage, on the basis of the state of engagement oil pressure of the predetermined friction engagement device.
(FR) La présente invention concerne un appareil de commande hydraulique de transmission automatique de véhicules qui possède une pluralité des dispositifs d'embrayage par friction hydraulique qui sont sélectivement en prise ou débrayés de façon à établir une pluralité d'étages de changement de vitesse en marche avant de différents rapports de changement de vitesse. Les étages de changement de vitesse en marche avant sont obtenus par la mise en prise de dispositifs d'embrayage par friction prédéterminés, de la pluralité des dispositifs d'embrayage par friction. Si on détermine qu'un étage de changement de vitesse prédéterminé correspondant à une sortie de changement de vitesse prédéterminée n'est pas établi, l'appareil de commande hydraulique identifie un dispositif d'embrayage par friction hydraulique dont la mise en prise est mauvaise entraînant le non établissement de l'étage de changement de vitesse prédéterminé, à partir de l'état de pression d'huile d'embrayage du dispositif d'embrayage par friction prédéterminé.
