An internal combustion engine () automatically stops when a predetermined idle stop condition is satisfied, and automatically restarts when a predetermined idle stop cancel condition is satisfied. The internal combustion engine () is controlled so that when fresh air does not flow into a GPF () even if fuel injection is stopped during operation of a vehicle, stop of the fuel injection is permitted even when temperature of GPF () is high. That is, the internal combustion engine () is controlled so that the stop of the fuel injection is forbidden when the temperature of the GPF () is higher than a predetermined temperature Tand the stop of the fuel injection is allowed when the vehicle stops in a state in which the temperature of the GPF () is higher than the predetermined temperature (T).

Method for controlling internal combustion engine, and device for controlling internal combustion engine

A control method is provided for an internal combustion engine which includes a turbocharger, and which is connected to a stepped automatic transmission. The control method includes judging whether or not an upshift of the automatic transmission is performed; performing a first torque down control by an ignition timing retard of the internal combustion engine during the upshift; judging whether or not a predicted torque estimated from a driving condition of the internal combustion engine is greater than a target torque at an end of the upshift; and performing a second torque down control by the ignition timing retard of the internal combustion engine when the predicted torque is greater than the target torque.
