Abstract:
1. A method for detecting a jammed charge movement flap of an internal combustion engine, the method comprising: ascertaining a measured volumetric air flow of the internal combustion engine and a modeled volumetric air flow of the internal combustion engine; selecting an allowable predefined value from which the measured volumetric air flow may deviate from the modeled volumetric air flow; comparing the measured volumetric air flow and the modeled volumetric air flow to determine if a deviation of the measured volumetric air flow from the modeled volumetric air flow is greater than the predefined value; and in response to a determination that a deviation of the measured volumetric air flow from the modeled volumetric air flow is greater than the predefined value, automatically detecting a jammed charge movement flap.
