Abstract

A method and a device for the dynamic monitoring of an air charging system of an internal combustion engine, subsystems of the air charging system having a low-pass characteristic, and a characteristic state quantity that is to be measured being compared with a modeled, identical state quantity. The measured signal and the modeled signal are filtered using a high-pass filter or bandpass filter, and, given a change in the characteristic state quantity that is to be measured, higher-frequency signal portions are evaluated, which is advantageous with regard to the recognition of so-called slow response errors.
