    The output side rotation speed is less than or equal to a predetermined minimum threshold value, the throat valve opening value is less than or equal to the determination reference value set corresponding to the target gear shift stage, the target gear shift stage is one gear, and the engine torque is less than or equal to the preset specific value. If the above is not satisfactory, set the power on down shift shifting control mode.
    And a final target gear shift stage of the power-on downshift shift control mode is derived based on the output shaft rotation speed and the throttle valve opening value.
