Abstract
A device for determining the rotation frequency of at least one wheel of a vehicle provides a first measuring device for measuring an acceleration value of the at least one wheel, a second measuring means for measuring vibrations of the at least one wheel, and a processing unit configured to determine a first rotation frequency of the at least one wheel from the measured acceleration value of the at least one wheel, compare the determined first rotation frequency of the at least one wheel to a first threshold, define a frequency analysis interval from the determined first rotation frequency greater than the first threshold, process a frequency analysis of a signal indicative of vibrations of the at least one wheel for the frequencies inside the frequency analysis interval, and select a second rotation frequency in the frequency analysis interval having the higher amplitude.
