A method of compensating inaccuracies in a wheel speed sensor wherein signal-forming elements are arranged on a sensor wheel and wherein a determined angle is allocated to a given number of signal-forming elements to determine a wheel speed, and wherein the wheel speed is determined by evaluating the time during which the wheel rotates around the angle, wherein a correction factor which is included in the determination of the wheel rotational speed is memorized with respect to each element to compensate for variations of the signal-forming elements and/or the positioning of the elements, and the correction factors are updated during the driving operation, wherein updating is performed so that the non-corrected wheel speed measured by the sensor is compared with a reference value of the wheel speed established by means of a calculating model, and the correction factor is updated in dependence of this comparison.
