Abstract
An apparatus for calculating a filling time in an automatic transmission and a method thereof are disclosed. The apparatus includes an oil temperature detection unit for detecting an oil temperature of a transmission oil, a control duty input unit for receiving a control duty for controlling a solenoid valve that discharges or fills the transmission oil supplied from an oil pump from or to an oil flow path corresponding to a gear shifting stage to form a hydraulic pressure, a storage unit for storing a filling time table in which a relationship between a remaining flow and a filling time according to the oil temperature is mapped, and a calculation control unit for receiving the control duty of the solenoid valve from the control duty input unit to calculate the remaining flow on the basis of a variation interval of the remaining flow and an elapsed time, and calculating the filling time depending on the filling time table stored in the storage unit on the basis of the remaining flow.
