Original Abstract Submitted
A method for determining a rotational frequency of a wheel, in particular of a motor vehicle, with the aid of a rotational speed sensor including an encoder wheel assigned to the wheel and a sensor element assigned to the encoder wheel, the encoder wheel having impulse sensors that are distributed uniformly over its circumference at a distance from one another, whose flanks are detected by the sensor element for determining the rotational frequency of the encoder wheel. In the method, for the purpose of compensating for a modulation of the rotational frequency caused by an eccentricity, the encoder wheel is divided into segments, a pulse frequency of detected signal impulses is ascertained and averaged for each segment, and as a function of the averaged pulse frequencies, modulation parameters are determined for correcting the rotational frequency.
