Abstract
A control system for an automatic transmission is provided with a manual shift mode capable of performing a shift command made by manual operation. While in the manual shift mode and during the operation of a downshift command generated by a shift lever, a manual shift control unit calculates a degree of power required by a driver that, for example, takes into consideration an operation intent of the driver and a road condition. A post-downshift shift speed is then determined in accordance with the degree of required power and downshifting performed. By performing only one downshift command through manual operation, downshifting in accordance with the degree of power required by the driver is performed. Downshifting to a shift speed desired by the driver can thus be promptly performed, without the operation becoming a burden.
