Abstract
The disclosure relates to a method for operating a rotational speed sensor of a motor vehicle with a signal encoder ring having a plurality of magnet elements arranged uniformly over its circumference with alternating orientation, and with a signal receiver having at least two sensor elements arranged uniformly apart from one another for sensing magnetic fields of the magnets. Information bits are generated based on magnetic field strengths detected by the sensor elements and made available as a rotational speed information signal. At a low rotational speed, an additional rotational speed information signal is generated and added to the rotational speed information signal. The additional signal comprises additional rotational speed pulses inserted between two normal rotational speed pulses. As a result, a plurality of rotational speed pulses are available per period of the encoder ring and a higher resolution of determination of the speed becomes possible.
