Abstract
An object is to provide a DPF regeneration control device whereby it is possible to prevent clogging of a DOC more efficiently than conventional techniques, and to recover the DOC securely from a clogging condition even if the DOC is actually clogged. A DPF regeneration control device () includes: a DPF temperature-increase unit (A) including a first temperature-increase unit () configured to heat a DPF () to a predetermined temperature, and a second temperature-increase unit () configured to heat the DPF to a temperature higher than the predetermined temperature in cooperation with the first temperature-increase unit; a DOC clogging detection unit (D) configured to detect that a DOC () is clogged if a clogging parameter detected during execution of the automatic regeneration exceeds a clogging threshold value determined in advance for a predetermined period, the clogging parameter being related to clogging of the DOC, and a DOC clogging countermeasure unit (C) configured to stop the automatic regeneration and issue an alert to prompt execution of the manual regeneration, if the clogging of the DOC is detected.
