Abstract

A control apparatus for an internal combustion engine is configured to: calculate measured data of MFB using an output signal of an in-cylinder pressure sensor after performing a first low-pass filtering; execute engine control based on the measured value of a specified fraction combustion point that is calculated based on the measured data of MFB; and prohibit the engine control when the first correlation index value is less than a first determination value and a first correlation degree is lower than a first degree.
