Abstract
An internal combustion engine includes a filter that is provided in an exhaust passage and traps particulate matter in an exhaust gas, and a pressure sensor that detects pressure information including a pressure on an exhaust upstream side of the filter. A controller executes an accumulation amount calculation process of calculating an accumulation amount of the particulate matter accumulated in the filter based on the pressure information. The accumulation amount calculation process includes correcting the accumulation amount of the particulate matter in accordance with a degree of variation in the accumulation amount of the particulate matter along an exhaust flow direction of the filter.
Claims5
A controller configured to control an internal combustion engine, the internal combustion engine including a filter that is provided in an exhaust passage and traps particulate matter in an exhaust gas, and a pressure sensor that detects pressure information including a pressure on an exhaust upstream side of the filter, the controller comprising processing circuitry, wherein
- the processing circuitry is configured to execute an accumulation amount calculation process of calculating an accumulation amount of the particulate matter accumulated in the filter based on the pressure information, and
- the accumulation amount calculation process includes correcting the accumulation amount in accordance with a degree of variation in the accumulation amount of the particulate matter along an exhaust flow direction of the filter.
