<p>PROBLEM TO BE SOLVED: To provide a diesel particulate filter device capable of easily correcting judging values for judging regenerating time by a judging value renewing means without altering the control program inside at on-vehicle time and when coping with a variation in an output value by a change with the lapse of time of exhaust pressure sensors. SOLUTION: In this diesel particulate filter device 1 having plural filter units 10 and 20 for exhaust emission control and alternately performing the exhaust emission control and regeneration, a control device 40 for judging the regenerating time on the basis of a detecting value of the upstream side and downstream exhaust pressure sensors 31, 32 and 33 of the filter units 10 and 20, is provided with the judging value renewing means 40a for resetting the judging values R1 and R2 for judging the regenerating time by comparing the detecting value with a standard exhaust pressure value R00.</p> |
