Title (EN) ALARM METHOD FOR INDICATING THE WEAR OF A TYRE WITH A FURROW
(FR) PROCEDE D'ALERTE CONCERNANT L'USURE D'UN PNEUMATIQUE MUNI D'UN SILLON
Abstract:
(EN) The invention relates to an alarm method pertaining to the wear of a tyre (10) having a tread (12) with at least one circumferential furrow (14), comprising: measuring the rolling noise of the tyre (10) on the ground; isolating, from the measured rolling noise, a noise generated in a predetermined frequency range close to a predetermined resonance frequency of a segment of the furrow (14) upon rolling; measuring the amplitude of the isolated noise; comparing the measured amplitude to a predetermined alarm threshold.
(FR) L'invention concerne un procédé d'alerte concernant l'usure d'un pneumatique (10) comprenant une bande de roulement (12) munie d'au moins un sillon circonférentiel (14), dans lequel : on mesure le bruit de roulage du pneumatique (10) sur un sol, on isole, parmi le bruit de roulage mesuré, un bruit émis dans une plage prédéterminée de fréquences voisines d'une fréquence prédéterminée de résonance d'un tronçon du sillon (14) lors du roulage, on mesure l'amplitude du bruit isolé, on compare l'amplitude mesurée avec un seuil d'alerte prédéterminé.
