Title (EN) METHOD AND DEVICE FOR DETERMINING A WHEEL LOAD ACTING ON A WHEEL OF A VEHICLE, AND METHOD AND DEVICE FOR DETERMINING A WEIGHT OF A VEHICLE
(FR) PROCÉDÉ ET DISPOSITIF DE DÉTERMINATION D'UNE CHARGE DE ROUE AGISSANT SUR UNE ROUE D'UN VÉHICULE, AINSI QUE PROCÉDÉ ET DISPOSITIF DE DÉTERMINATION DU POIDS D'UN VÉHICULE
Abstract:
(EN) The invention relates to a method for determining a wheel load (WL) acting on a wheel (W) of a vehicle (1), wherein the wheel (W) comprises a rim and a tire mounted onto the rim, and a sensor unit (12) mounted at the wheel (W), wherein the method comprises: (a) determining a tire pressure (p) of the tire by means of the sensor unit (12), (b) determining a tire footprint of the tire by means of the sensor unit (12), when the vehicle (1) is driving, (c) determining the wheel load (WL) based on a predetermined relationship between the wheel load (WL), the tire pressure (p) and the tire footprint,(d) analysing temporal variations of the tire pressure (p) during a standstill period of the vehicle (1) for determinin gone or more parameters indicating the temporal variations of the tire pressure (p), and (e) estimating a change (dWL) of the wheel load (WL) during the standstill period based on the one or more determined parameters. The invention further relates to a device for determining a wheel load (WL), and a method and a device for determining a weight of a vehicle (1).
(FR) La présente invention concerne un procédé de détermination d'une charge de roue (WL) agissant sur une roue (W) d'un véhicule (1), la roue (W) comprenant une jante et un pneu monté sur la jante, et une unité de capteur (12) montée au niveau de la roue (W), le procédé comprenant les étapes consistant à : (a) déterminer une pression de pneu (p) du pneu au moyen de l'unité de capteur (12), (b) déterminer une empreinte de pneu du pneu au moyen de l'unité de capteur (12), lorsque le véhicule (1) est conduit, (c) déterminer la charge de roue (WL) sur la base d'une relation prédéterminée entre la charge de roue (WL), la pression du pneu (p) et l'empreinte du pneu, (d) analyser des variations temporelles de la pression du pneu (p) pendant une période d'arrêt du véhicule (1) pour déterminer un ou plusieurs paramètres indiquant les variations temporelles de la pression du pneu (p), et (e) estimer un changement (dWL) de la charge de roue (WL) pendant la période d'arrêt sur la base du ou des paramètres déterminés. La présente invention concerne en outre un dispositif de détermination d'une charge de roue (WL), ainsi qu'un procédé et un dispositif de détermination du poids d'un véhicule (1).
