Abstract: The invention relates to a method for operating a compressor in the intake section of an internal combustion engine, in particular of a motor vehicle. A state variable which describes the behavior of the compressor, for example the frequency and/or amplitude of the intake air flow, is monitored. If the state variable exceeds or drops below at least one predefined or predefinable limiting value, intervention is carried out in a regulating and/or controlling fashion. A particularly simple way of implementing this method is obtained in that an output signal, generated for regulating and/or controlling the internal combustion engine, of an air flow sensor which is arranged in the intake tract is used as the state variable.
