Abstract: PURPOSE: An oil temperature modeling method is provided to model an oil temperature precisely without an oil temperature sensor by using the starting coolant temperature and the integral value of MAF(Mass Air Flow). CONSTITUTION: An oil temperature modeling method comprises steps of calculating an oil temperature change possibility which represents a changeable range of oil temperature(S210), obtaining a working oil temperature change possibility from the oil temperature change possibility in consideration of vehicle operation(S220), and calculating the final oil temperature model by adding the working oil temperature change possibility to the existing oil temperature model(S230). The oil temperature change possibility is calculated by subtracting the existing oil temperature model from the value that an oil temperature gradient and an oil temperature offset value are added to an oil temperature raw value.
