Claim 0:
1. A method for determining a rotation frequency of at least one wheel of a vehicle, the method comprising:
determining a first rotation frequency of the at least one wheel from an acceleration value of the at least one wheel,
comparing the determined first rotation frequency of the at least one wheel to a first predetermined threshold,
defining a frequency analysis interval from the determined first rotation frequency greater than the first threshold,
wherein the first threshold is 4.2 Hz,
processing a frequency analysis of a signal indicative of vibrations of the at least one wheel for frequencies inside the frequency analysis interval, and
selecting a second rotation frequency in the frequency analysis interval having the higher amplitude, the second rotation frequency being equal to the rotation frequency of the at least one wheel.
