The invention relates to a wheel speed calculation method comprising the steps of: recording (E1), during a predefined period, values taken by a clock, encoded on a bit number Nb, when electrical pulses are received, and calculating (E2) a wheel speed, wherein the wheel speed is calculated when the number of received electrical pulses is less than the number of returns to the zero value of the clock, with R being the pre-recorded wheel radius, N being the number of teeth of the wheel speed sensor used, and Δt(n) = [top k - top k _ 1 + (2Nb - 1)n] * T, where topk is the kth electrical pulse clock value, and T is the period of said clock, n being such that j is the number of received electrical pulses. |
