Beschreibung
Zusammenfassung:	The device has a controller connected to a speed sensor and comprising an analyzing unit for carrying out frequential analysis of the speed sensor. A determination unit determines engine speed, and is connected to the controller, where the controller comprises a filter unit for frequential analysis of the speed sensor by utilizing the determined engine speed. The filter unit comprises multiple filter parts and a notch filter for filtering harmonics of the engine. An independent claim is also included for a frequential analysis method of a wheel speed sensor of a car. L'invention concerne un dispositif d'analyse fréquentielle d'un capteur de vitesse de roue d'un véhicule automobile comportant : -des roues reliées au châssis du véhicule, -des capteurs de vitesse des roues, et -un calculateur relié aux capteurs de vitesse et comportant un moyen apte à effectuer l'analyse fréquentielle des capteurs de vitesse, caractérisé en ce que le dispositif comporte un moyen de détermination du régime moteur, ledit moyen de détermination du régime moteur étant relié au calculateur, et en ce que le calculateur comporte un moyen de filtrage de l'analyse fréquentielle des capteurs de vitesse des roues selon le régime moteur.
