Abstract
A method for determining a combustion chamber pressure of an internal combustion engine is described, which is used for a simple and accurate correction of the determined combustion chamber pressure. For this purpose, a first time curve of the combustion chamber pressure is compared with a second time curve of the combustion chamber pressure. A correction factor is determined as a function of the comparison result. The determined combustion chamber pressure is corrected via the correction factor.
