Abstract
A device for recognizing the angular position of a rotating part is described in which the rotating part is a pick-up disc (14) provided with a multiplicity of regular angle marks (11) and a distinguishable reference mark (12), which is formed, for example, by two missing angle marks (11). The number of angle marks is (n-2), where n is a number which is divisible by as many numbers as possible corresponding to different numbers of cylinders and, for example, is 36. The voltage sequence generated in the sensor (15) is analyzed in the control unit (19), unambiguous cylinder recognition being obtained after the recognition of the reference mark (12) by comparison with a camshaft signal. The analysis of the voltage sequence also supplies the rotational speed and flanks, which can be predetermined, of the pulse sequence used for ignition and/or injection control.
