Abstract
An internal combustion engine control apparatus includes a pseudo knock determination unit that determines whether or not a pseudo knock has been produced in a knock detection window, based on at least one of the frequency, a status amount indicating a rotation speed of the internal combustion engine, a status amount indicating a load of the internal combustion engine, and a status amount indicating an air-fuel ratio of the internal combustion engine; and a moving-average processing unit that sets a second period to a period that is approximately the same as a first period, in the case where it has been determined that the pseudo knock was not produced, and that does not implement moving-averaging or sets the second period to a period that is narrower than the first period, in the case where it has been determined that a pseudo knock was produced.
