INTERNAL COMBUSTION ENGINE CONTROL APPARATUS

摘要

An object of this invention is, in an internal combustion engine control apparatus whose operations are controlled by a plurality of kinds of actuators, to make it possible to ensure realization of at least a performance that is demanded with highest priority among performances being demanded of the internal combustion engine even when any one of a demanded torque, a demanded efficiency, and a demanded air-fuel ratio that are demanded values of controlled variables changes at a fast rate that exceeds a response speed of the related controlled variable with respect to an actuator. To achieve this object, 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.
