Regeneration control device and regeneration control method of diesel particulate filter

摘要

A regeneration control device of a diesel particulate filter, includes: a regeneration control unit configured to combust particulate matter accumulated in a diesel particulate filter that removes the particulate matter from exhaust gas of an engine and regenerate the diesel particulate filter when an accumulation amount of the particulate matter accumulated in the diesel particulate filter exceeds a predetermined value, wherein the regeneration control unit is configured to perform lower limit control in which a lower limit of an engine speed is set to a value greater than or equal to a predetermined threshold value during the regeneration.
