Abstract

A method for operating an internal combustion engine, including collecting a knocking signal of a knocking sensor and collecting a cylinder pressure signal of a cylinder pressure sensor. The cylinder pressure signal is representative of a cylinder pressure prevailing in at least one combustion chamber of the internal combustion engine. The method further includes determining an estimated cylinder pressure on the basis of a model and the knocking signal, and subjecting the cylinder pressure signal to a plausibility check. The method further includes, if the cylinder pressure signal is not plausible according to the plausibility check, using the estimated cylinder pressure for the operation of the internal combustion engine.
