CONTROL APPARATUS AND CONTROL METHOD FOR AN INTERNAL COMBUSTION ENGINE

摘要

A control apparatus for an internal combustion engine is provided with a cylinder pressure sensor (11 to 14) in each cylinder of an engine (10). The control apparatus performs a correction to eliminate variation in output characteristics of the cylinder pressure sensors when controlling the combustion states of the cylinders based on the detected cylinder pressures so that the combustion states are uniform. In this correction, the output characteristic of each cylinder pressure sensor is expressed as a linear function, and the gain and offset of the output characteristic of a cylinder pressure sensor is corrected such that the output characteristic of each cylinder pressure sensor matches a common reference output characteristic that was set in advance.
