摘要： Transmission shocks and idling defects such as engine racing and rough idling due to aging of a throttle opening area are prevented from occurring. An internal combustion engine control apparatus for controlling an internal combustion engine that has an air flow rate sensor for measuring a rate of air represented as an actual air rate, the air flowing into a cylinder, and a throttle valve for adjusting the rate of air, includes a throttle valve controlling section for controlling a throttle opening of the throttle valve to reach a preset throttle opening set depending on a target air rate for realizing a demand torque, and a throttle opening correcting section for correcting the preset throttle opening on the basis of the target air rate upon fuel cutoff that stops a fuel from being supplied to the internal combustion engine and of an actual air rate measured by the air flow rate sensor.
