In emergency regeneration, i.e., after a judgment is made that purification is insufficient after ending forced regeneration, forced regeneration has expired before completion, or when a pressure difference across a diesel particulate filter exceeds a predetermined first judging pressure difference when traveling distance of a vehicle is shorter than a predetermined distance, an alarm for urging manual regeneration is issued. When manual regeneration is designated thereafter by the vehicle's user, manual regeneration is performed. When predetermined conditions are satisfied before receiving a designation of manual regeneration, automatic regeneration is performed. |
