Abstract

L'invention concerne un véhicule automobile équipé d'un dispositif de détection qui émet et reçoit des ondes électromagnétiques à une bande de fréquence effective située dans une gamme de fréquences comprise entre 10 GHz et 100 GHz, pour déterminer la distance, la vitesse, la classe, la position d'un objet se trouvant dans l'environnement du véhicule, en tant que propriété relative. Un manchon constitué d'un matériau présentant un effet absorbant dans la bande de fréquence effective du dispositif de détection est positionné entre le dispositif de détection et une pièce ajoutée sur le véhicule derrière laquelle se trouve le dispositif de détection. Ce manchon sert à réduire ou empêcher, d'une part, l'établissement d'une diaphonie entre ledit dispositif de détection et un dispositif de détection supplémentaire ou entre une branche de réception et une branche d'émission dudit dispositif de détection, et d'autre part, l'altération des performances de détection par des projections d'eau ou sous l'effet de la saleté.
