Abstract
La présente invention concerne un procédé de détection d’une fuite ou d’un sous gonflage d’un pneumatique d’une roue d’un véhicule, comprenant les étapes de : - mesure périodique, d’une valeur (VFP) caractéristique de l’empreinte au sol du pneumatique par un module pneumatique (14) ; - envoi, à une unité centrale électronique (12) équipant le véhicule, de la valeur caractéristique mesurée accompagnée d’une information d’identification (ID14) du module pneumatique ; - collecte, par l’unité centrale électronique, d’une valeur de charge (C) pour la roue correspondante ; - mémorisation (MEM), par l’unité centrale électronique et pour ladite roue, de la valeur caractéristique mesurée et de la valeur de charge collectée ; - détection d’une fuite ou d’un sous gonflage du pneumatique lorsque la valeur caractéristique mesurée pour ladite roue augmente tandis que la valeur de charge associée demeure constante ; - et alerte (AL) au conducteur le cas échéant. Figure pour l’abrégé : Fig ure 3The present invention relates to a method for detecting a leak or under-inflation of a tire of a wheel of a vehicle, comprising the steps of: - periodic measurement of a value (VFP) characteristic of the footprint of the tire by a pneumatic module (14); - sending, to an electronic central unit (12) fitted to the vehicle, the measured characteristic value accompanied by identification information (ID14) of the pneumatic module; - collection, by the electronic central unit, of a load value (C) for the corresponding wheel; - memorization (MEM), by the electronic central unit and for said wheel, of the measured characteristic value and the collected load value; - detection of a leak or under-inflation of the tire when the characteristic value measured for said wheel increases while the associated load value remains constant; - and alert (AL) to the driver if necessary.
