Abstract
A control device for an internal combustion engine includes an in-cylinder pressure sensor, a crank angle sensor, and an electronic control unit. The electronic control unit is configured to calculate a correlation index value showing a degree of a correlation between a actually measured data of a combustion mass ratio and reference data of the combustion mass ratio based on an operating condition of the internal combustion engine. The electronic control unit is configured to, in a case where the correlation index value is lower than a determination value, prohibit the actually measured value of the specific ratio combustion point pertaining to a combustion cycle in which the correlation index value is calculated from being reflected in the engine control or reduce a degree of the reflection in the engine control compared to a case where the correlation index value is equal to or higher than the determination value.
