Abstract

Ce procédé de mesure du taux de patinage d'un véhicule automobile (12) au cours du déplacement de ce véhicule (12), comporte les étapes suivantes : - la mesure d'une vitesse de déplacement réelle Vr du véhicule (12) par rapport au sol (26) ; - la mesure de la vitesse de rotation d'au moins une roue (16) du véhicule (12) ; - la détermination d'une vitesse théorique de roulement Vth, produit de la vitesse de rotation d'au moins une roue (16) du véhicule (12) par la circonférence de ladite roue (16) du véhicule (12) ; - le calcul du taux de patinage Tpat selon la formule : Tpat = 1 - Vr/ Vth.This method of measuring the slip rate of a motor vehicle (12) during the movement of this vehicle (12), comprises the following steps: - measuring a real speed of movement Vr of the vehicle (12) relative to on the ground (26); measuring the speed of rotation of at least one wheel (16) of the vehicle (12); - Determining a theoretical rolling speed Vth, produces the rotational speed of at least one wheel (16) of the vehicle (12) by the circumference of said wheel (16) of the vehicle (12); the calculation of the slip rate Tpat according to the formula: Tpat = 1 - Vr / Vth.
