Internal combustion engine control device

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, the internal combustion engine control apparatus comprising:

• 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 a 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, wherein
• the throttle opening correcting section corrects the preset throttle opening when a difference between the target air rate during the fuel cutoff and the actual air rate measured by the air flow rate sensor is equal to or larger than a preset value.
