Abstract: PURPOSE: A device and method for controlling shifting of an automatic transmission for a vehicle is provided to prevent a vehicle from being pushed backward when a vehicle starts on a sloping road. CONSTITUTION: A device for controlling shifting of an automatic transmission for a vehicle comprises a device for detecting moving and traveling of a vehicle(100), a unit for controlling shifting(200), and a driving unit(300). The device for detecting moving and traveling of a vehicle detects the state of traveling of the vehicle. The unit for controlling shifting outputs a control signal to the device for detecting moving and traveling of a vehicle, receives the state of the shifting mode, throttle valve opening, rotational frequency of the output shaft, rotational frequency of the engine, and the position of a gear shift lever, and decides the state of the road. The unit for controlling shifting outputs a control signal of two-speed brake if a stop of the vehicle on a sloping road at N range is decided, and releases two-speed brake and at the same time outputs a one-speed control signal for a forward movement if a start of the vehicle on the sloping road is decided. The driving unit performs shifting by supplying hydraulic pressure discharged from an oil pump with duty control by a duty control signal of speed change control output from the unit for controlling shifting to an appropriate frictional element, and releasing.
