Abstract
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.
