ABSTRACT:
A shift control system and a system control method for use in an automatic transmission includes: an input shaft, an output shaft, a gear train including a plurality of revolving components and arranged between the input shaft and the output shaft, a plurality of clutches for connecting either the input shaft and any of the revolving components or the revolving components selectively, a plurality of brakes for stopping revolution of the revolving components selectively, and a one-way clutch belonging to any of the clutches and the brakes. Any of the speed stages is set according to at least two of a combination pattern of engagement/release of the clutches and brakes for engaging the one-way clutch and a combination pattern of engagement/release of clutches and brakes for releasing the one-way clutch. The combination patterns are always selected so as to switch the one way clutch.
