Abstract
A control device for an internal combustion engine includes a filter for collecting PM in an exhaust pipe connected to an engine body, and a PM regeneration function for regenerating the filter for collecting PM. The control device of the internal combustion engine includes a filter differential pressure acquisition unit that acquires a filter differential pressure, a pre-regeneration filter differential pressure acquired by the filter differential pressure acquisition unit prior to regeneration of the filter, a pre-post regeneration differential pressure difference acquisition unit that acquires a pre-regeneration differential pressure difference that is a difference between a post-regeneration filter differential pressure acquired by the filter differential pressure acquisition unit after regeneration of the filter, and a PM generation function determination unit that performs an anomaly determination of PM regeneration function when the acquired pre-regeneration differential pressure difference is equal to or less than a preset threshold.
