Abstract

Un procédé d’estimation est mis en œuvre dans un véhicule circulant sur une surface et comprenant un train comportant deux roues comprenant chacune une jante conductrice électriquement et sur laquelle est monté un pneu. Ce procédé comprend une étape (10-40) dans laquelle on mesure une résistance électrique entre deux jantes isolées entre elles au niveau du véhicule, puis on estime une adhérence des roues en fonction de cette résistance électrique mesurée. Figure à publier avec l’abrégé : Fig. 2An estimation method is implemented in a vehicle traveling on a surface and comprising a train comprising two wheels each comprising an electrically conductive rim and on which a tire is mounted. This method comprises a step (10-40) in which an electrical resistance is measured between two rims insulated from each other at the level of the vehicle, then an adhesion of the wheels is estimated as a function of this measured electrical resistance. Figure to be published with the abstract: Fig. 2
