Abstract (en)
[origin: WO2012136407A1] The invention relates to a method for diagnosing a supercharging system, in which the frequency spectrum generated during rotation of the supercharging system is detected by means of measurement data capture and the detected frequency spectrum is evaluated by a frequency analysis by means of a measurement data evaluation. A frequency characteristic of the supercharging system for at least one predefined operating point of the supercharging system determined by the frequency analysis is compared to a predefined vehicle-specific frequency characteristic of the supercharging system for the at least one predefined operating point.
