A controller in a form of an engine controller controls an aftertreatment device for a residual substance in exhaust gas. The engine controller includes a regeneration occurrence-condition output unit that outputs regeneration occurrence-condition data indicating occurrence of a regeneration treatment of the aftertreatment device, and a regeneration division detector that detects division of the regeneration treatment by a key-off operation conducted during execution of the regeneration treatment. The regeneration occurrence-condition output unit outputs regeneration occurrence-condition data that is analyzable to show that a regeneration treatment before the division detected by the regeneration division detector and a regeneration treatment after the division are a series of regeneration treatments.

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.
