The present invention relates to a method for controlling a starting clutch of an automatic transmission in a vehicle comprising the steps of: determining whether or not the vehicle speed is increased beyond the maximum creeping speed of the present change gear while a controller carries out a creep control; controlling the starting clutch to shift up the change gear when the vehicle speed exceeds the maximum creeping speed; determining whether or not the vehicle speed is decreased below the minimum creeping speed of the present change gear while the controller carries out the creep control; and controlling the starting clutch to shift down the change gear when the vehicle speed is decreased below the minimum creeping speed. Because the starting clutch is controlled according to the creeping speed at the time of the creep control of the automatic transmission of the vehicle in order to shift the change gears, the present invention can carry out creep control at a target creeping speed.
