Abstract:
A combustion pressure detection method and a combustion pressure detection apparatus of an internal combustion engine that can detect combustion pressure by using a crank angle sensor in an accurate and easy way. A relationship between a crank angle sensor signal and a combustion pressure signal is previously recorded. As a result, even if the combustion pressure sensor fails, the combustion pressure is detected by collating the crank angle sensor signal with the relationship.

Claim (Index 3):
The internal combustion engine control apparatus according to  claim 1 ,\n wherein in a case where pressure of a cylinder other than the predetermined cylinder is estimated, the processor corrects a measured crank angle sensor signal so as to correspond to the reference cylinder and obtains the in-cylinder pressure of the cylinder by collating the signal of the corrected crank angle sensor with the relationship between the crank sensor signal and the in-cylinder pressure of the predetermined cylinder, the relationship being stored in the memory.
