Abstract
An engine control device that can suppress thermal degradation of a particulate filter is provided. The device executes a fuel injection control module that restricts the supply of fuel by an injector if a fuel cutting condition is satisfied, an accumulation estimation module that estimates the accumulated amount of soot trapped in a GPF, and a regeneration control module that performs regeneration control for regenerating the GPF by burning soot if the accumulated soot amount exceeds a predetermined setting amount. A fuel cut prohibition line is set in advance and defines a prohibition temperature at which fuel cutting control is to be prohibited in accordance with the accumulated soot amount. The device further executes a prohibition control module that prohibits performance of fuel cutting control by the fuel injection control module if the temperature of the GPF is higher than the prohibition temperature.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
