Abstract
A change in a torque request for an internal combustion engine during a prediction period is predicted as a change in a target torque. Further, a change in an outputtable upper-limit torque during the prediction period is calculated as an upper-limit torque change. When the target torque is greater than the upper-limit torque by more than a judgment value during the prediction period, control is exercised to increase an intake air amount. Moreover, the torque difference between the target torque and upper-limit torque at a second time, which is later than a first time, is calculated to correct the torque difference with higher responsiveness than exhibited for intake air amount control.
