Abstract
An internal combustion engine control apparatus controls an air intake mass at an idle state after a start of an internal combustion engine based on a correction mass of the air intake mass calculated based on a desired value of the air intake mass and a measured value of the air intake mass. The air intake mass is controlled based on an idle speed control variable corresponding to the desired value of the air intake mass, and an idle speed control variable at when the correction mass is calculated. Each idle speed control variable includes a degree of a throttle opening or a degree of an idle speed control valve opening.
