Abstract
When a change amount of any one of a demanded torque, a demanded efficiency, and a demanded air-fuel ratio exceeds a predetermined threshold value, an internal combustion engine control apparatus provided by this invention makes a temporary adjustment to a value of any one of a demanded torque, a demanded efficiency and instructed efficiency, and a demanded air-fuel ratio in accordance with a type of demanded engine performance that is currently being given priority among various performances demanded of the internal combustion engine. In the present control apparatus, an actuator for air amount control is operated in accordance with a target air amount calculated based on a demanded torque and a demanded efficiency, an actuator for ignition timing control is operated in accordance with an instructed efficiency, and an actuator for fuel injection amount control is operated in accordance with a demanded air-fuel ratio.
