ABSTRACT:
A method for the exact determination of the speed of a rotating part, in particular the speed of the wheel of a motor vehicle, in which discontinuities present on the circumference of the rotating part are scanned without contact, an electric pulse being produced upon the detection of each discontinuity and the number of pulses thus produced being counted. In order definitely to be able to determine the dynamism of a rotating part without manufacturing tolerances of the incremental disks influencing this, the period of time within which all pulses of the rotating part are counted precisely once is determined, and the speed of the rotating part is determined therefrom.
