METHOD FOR MEASURING THE ROTATIONAL SPEED OF A VEHICLE WHEEL

Method for measuring the rotational speed of a wheel comprising the steps of: - acquiring an analog measurement signal (Sma) generated by a magnetic tachometer and containing a useful signal whose frequency is representative of the rotational speed of the wheel; - digitizing in real time the analog measurement signal (Sma) to obtain a temporal digital measurement signal (Smnt); - calculating a Fourier transform of the temporal digital measurement signal (Smnt) to obtain a frequency digital measurement signal (Smnf); - performing a frequency analysis to identify by a maximum search a useful line (16) so as to obtain the frequency of the useful signal and therefore the rotational speed of the wheel.
