Abstract:
If a mode-detection value is switched from an automatic shift-mode to a manual shift-mode, a T-ECU changes a shift-stage to a speed lower than a speed that is obtained before the switching of the mode-detection value. The T-ECU determines that a state of the T-ECU returns to a recognizable-state, in which a mode-selection value can be recognized, from an unrecognizable-state, in which the mode-selection value cannot be recognized. The T-ECU sets the shift-stage to a hold value after the return. The T-ECU controls the shift-stage in the automatic shift-mode “D” over a standby-period after the return. The T-ECU controls the shift-stage in the automatic shift-mode “D” until the detection of the operation of the shift-lever after the standby-period passes.
