Abstract

Un dispositif de détection d'usure de pneu, selon un mode de réalisation de la présente invention, comprend : un premier corps qui est inséré et positionné dans la surface extérieure d'un pneu ; un second corps qui est inséré et positionné dans la surface intérieure du pneu de façon à correspondre au premier corps, et est ainsi relié au premier corps ; une unité de source d'alimentation qui comprend une ligne de borne d'entrée et une ligne de borne de sortie, est connectée au second corps par l'intermédiaire de la ligne de borne d'entrée et de la ligne de borne de sortie, et fournit un courant électrique au second corps ; et une unité de traitement qui est connectée à la ligne de borne d'entrée et à la ligne de borne de sortie, mesure une valeur d'usure comprenant l'une d'une valeur de courant électrique et d'une valeur de tension, et génère un signal de sortie en fonction de la valeur d'usure mesurée, le premier corps étant usé alors que la surface extérieure du pneu est usée, et l'unité de traitement mesure une valeur d'usure changeante pour générer le signal de sortie.
