Patent abstract
A control apparatus for an internal combustion engine is configured to: calculate measured data for MFB in synchrony with crank angle based on in-cylinder pressure detected by an in-cylinder pressure sensor; execute SA-CA10 feedback control and CA50 feedback control based on a measured CA10 and a measured CA50 that are calculated based on the measured data; execute engine control based on a degree of correlation between the MFB measured data and the reference data that corresponds thereto; and generate reference data for a combustion period by linear interpolation and linear extrapolation based on a target CA50 and a specified CA10.
