<p>When an engine speed is in a low speed region, a fuel injection amount is calculated at a first calculation timing (at an angle interrupt process of the crank angle) which is immediately after detection of a peak engine speed (S220). Accordingly, the peek engine speed is reflected on an output with high responsiveness, and hunting and engine stalling can be prevented. When the engine speed is in medium and high speed regions, the fuel injection amount is calculated at a second calculation timing which is prior to the first calculation timing (S214), and a fuel injection amounts that are obtained at a time interrupt process are actually reflected on the output. Accordingly, a margin is provided for arithmetic processing even in the medium and high speed regions, and a margin is further provided for another arithmetic processing which needs to be calculated at the first timing. Therefore, according to an internal combustion engine output control method and device, even in an arithmetic processing circuit having a processing speed, hunting and engine stalling are prevented, and a margin can be provided for an arithmetic computation even when the engine speed is high.
