PURPOSE: To reduce the shock at shift up of an automatic transmission varied from its non driven condition to its driven condition according to lowering of throttle opening effectively. CONSTITUTION: Whether a 1→2 flag for shifting up from one-speed to two-speed in back out state is provided or not is determined. (step S2). A delay timer DRY is set as an initial value KDR12BO if the 1→2 flag is provided (step S3), and this delay timer DRYT is subtracted by one (step S5, S6). A solenoid pattern is set as three-speed at the time the initial value KDR12BO passes (step S7) and also gear ratio KG32 lowered in the three-speed state is read in (step S8). The solenoid pattern is set as two-speed (step S10) when the current gear ratio KG32 is determined to be smaller than two-speed switched gear ratio gear (step S9). |
