The present invention relates to a method for controlling shifting when changing a power state, capable of controlling a hydraulic pressure by reflecting inertia torque of a vehicle to prevent a rapid change in hydraulic pressure when gear shifting is performed in a state that accelerating the vehicle is stopped. The method for controlling shifting when changing a power state, which is a shifting control method for controlling an automatic transmission by setting output torque of an engine as input torque of the automatic transmission in a power train including the engine and the automatic transmission, comprises: (S110) a power state change determination step of determining whether the state of the power train of the vehicle is changed; (S120) an input torque obtaining step of obtaining torque input into the automatic transmission by reflecting action of the inertia torque of the power train, which is input into the automatic transmission, when the state of the power train is changed from a power-on-state into a power-off-state; and (S140) a hydraulic control step of assuming a fact that the input torque of the automatic transmission, into which the inertia torque obtained in the input torque obtaining step (S120) is reflected, is input into the automatic transmission and controlling the automatic transmission by using the changed hydraulic pressure to allow conversion from a hydraulic pressure in a power-on-state into a hydraulic pressure in a power-off-state during a predetermined time. |
