Abstract
An integrating PM amount σ PM as an integrating value of a PM generating amount after DPF regeneration is read (S). The integrating PM amount and a first threshold value SLset in advance are compared, and the regenerating period of DPFis judged (S). Further, a differential pressure ΔPdf before and after DPFdetected by a differential pressure sensor, and a second threshold value SLare compared, and the regenerating period of DPFis judged (S). Regeneration processing of DPFis then performed when the integrating PM amount σ PM attains the first threshold value SLor tore, or the differential pressure ΔPdf attains a second threshold value SLor more (S).
