Claim 6:
7. The method of claim 1, wherein step D) further comprises:
d1) acquiring the second signal indicative of a speed of the vehicle;
d2) acquiring a third signal indicative of a speed of an engine of the vehicle;
d3) acquiring a fourth signal indicative of a neutral condition of the gearbox;
d4) acquiring a fifth signal indicative of a condition of a clutch of the vehicle;
d5) determining, based on the fourth signal, whether the gearbox is in the neutral condition or not in the neutral condition;
d6) determining, based on the fifth signal, whether the clutch is in an engaged condition or in a disengaged condition,
wherein, when in sub-step d5) it is determined that the gearbox is not in the neutral condition and in the sub-step d6) it is determined that the clutch is in the disengaged condition, then step D) further comprises:
d7) calculating a reference parameter based on:

M=K*(V/rpm), wherein:
M is the reference parameter;
K is a constant depending on a vehicle transmission;
V is the speed of the vehicle;
rpm is a number of revolutions of a drive shaft of the engine of the vehicle;
d8) defining a series of reference intervals for the parameter, wherein each reference interval is indicative of a gear engaged;
d9) determining the gear engaged based on the reference interval into which the parameter falls; and
d10) determining a direction of the gear shifting based on a comparison between the gear engaged determined in the sub-step d9) and the gear engaged before the gear shifting.
