Abstract: A method for calculating the effective volume of a diesel particulate filter is provided to reduce the time and cost required for compensating for the amount of ash by calculating the change in effective volume by ash using only the value measured by sensors regardless of the kind of a vehicle, the management condition of a vehicle, fuel consumption and oil consumption. A method for calculating the effective volume of a diesel particulate filter comprises the steps of: judging whether regeneration efficiency satisfies the learning condition of an ash coefficient or not(S230); if regeneration efficiency satisfies the learning condition of an ash coefficient, measuring exhaust flow rate(S250); calculating the change in the differential pressure by ash(S260); calculating the change in an ash coefficient using the change in the differential pressure by ash and the exhaust flow rate(S270); calculating a current ash coefficient using the change in an ash coefficient and a previous ash coefficient(S280); and calculating effective volume using the current ash coefficient and a first filter coefficient(S300).
