Abstract

Le système de l'invention permet de contrôler la pression des pneus d'un véhicule et affiche les valeurs de pression en temps réel sur un affichage de tableau de bord lorsque le véhicule roule. Une unité électronique (100) montée sur la tige de valve à l'intérieur de chaque pneu met en oeuvre un détecteur de pression (120) afin de mesurer périodiquement la pression du pneu, ainsi qu'un émetteur (170) transmettant les valeurs de pression mesurées, par transmission radioélectrique, à un récepteur monté sur le tableau de bord. Le récepteur commande un affichage qui indique au conducteur la pression du pneu en temps réel pour chaque roue. L'affichage émet également un avertissement lorsque la pression des pneus tombe au-dessous de certains seuils prédéfinis. Les valeurs de pression sont compensées par rapport à des variations de température dans le pneu et éventuellement par rapport à des changements d'altitude.
