Abstract

A method for determining the rotary speed of a compressor, e.g., a turbocharger of an internal combustion engine, includes detecting the pressure in a region that is downstream from the compressor and generating a corresponding pressure signal. The rotary speed of the compressor is obtained from periodic fluctuations of at least one component of the pressure signal.
