Abstract:
1. A control device that is used with an internal combustion engine and capable of exercising torque control by operating an intake actuator for adjusting an intake air amount and by making ignition timing adjustments, the control device comprising: a demanded torque setup unit which sets a demanded torque; a demanded efficiency setup unit which sets a demanded efficiency; a demanded air amount calculation unit which calculates a demanded air amount from the demanded torque and the demanded efficiency; an intake actuator operation amount calculation unit which calculates an operation amount of the intake actuator in accordance with the demanded air amount; an ignition timing retard amount calculation unit which calculates a torque that is generated when the intake actuator is operated by the operation amount at a predetermined ignition timing setting, and calculates an ignition timing retard amount that is necessary to achieve the demanded torque in accordance with the difference between the calculated torque and the demanded torque; and a demanded efficiency correction unit which, when a setting of the demanded torque that is generated by the demanded torque setup unit rapidly increases by an amount greater than a predetermined increase amount or at a rate higher than a predetermined increase rate, temporarily decreases a setting of the demanded efficiency in accordance with the rapid increase in the setting of the demanded torque.
