摘要：
The invention relates to a method for detecting the rotational speed of an internal combustion engine (1). According to the invention, a sector wheel (4) connected to a crankshaft (3) is scanned and the duration of the scanning of a sector of a specific size is determined. Correction factors which arc dependent on the working parameters are then extracted from the characteristics in order to correct the measured duration in relation to the rotational speed oscillations occurring periodically during the operation of the internal combustion engine (1).
