An electronic control unit (ECU) of an internal combustion engine calculates a present deposition quantity of exhaust particulate matters based on operating states of the engine such as a differential pressure of a diesel particulate filter (DPF). If the present deposition quantity exceeds a predetermined upper limit value, the ECU performs compulsory regeneration of the DPF to compulsorily combust and reduce the deposited exhaust particulate matters. The ECU determines that spontaneous regeneration occurs if a temperature of exhaust gas in the DPF is equal to or higher than a reference temperature. Thereafter, the ECU completes the compulsory regeneration to eliminate the deposited exhaust particulate matters if the ECU determines that the spontaneous regeneration stops and the deposition quantity becomes equal to or less than a predetermined lower limit value.
