Patent ID: 8038574

Claim:
A shift control apparatus for automatic transmissions, comprising: plural friction transfer mechanisms for transferring power of a driving force source and interrupting this transfer; plural transmission input shafts respectively coupled with the friction transfer mechanisms; and plural gear trains for selectively coupling together the transmission input shafts and a transmission output shaft by the selecting operation of plural synchromeshes, the shift control apparatus being configured such that: a desired gear position is achieved by coupling together the transmission input shaft with which one friction transfer mechanism is coupled and the transmission output shaft through a gear train and engaging the one friction transfer mechanism and disengaging the other friction transfer mechanism; and standby control is carried out by predicting a next gear position and operating a predetermined synchromesh based on a result of the prediction to couple together the transmission input shaft with which the friction transfer mechanism having not been used for the achievement of the desired gear position is coupled and the transmission output shaft through a predetermined gear train and bring the transmission input shaft and the transmission output shaft into standby state, wherein the shift control device apparatus is configured so as to carry out timing with which operation for synchromesh coupling by the standby control is started, under condition of determining that the friction transfer mechanism having not been used for achievement of the desired gear position has been disengaged regardless of completion of the achievement of the desired gear position.
