Abstract

L'invention concerne un composant d'un nouveau type permettant la détection optoélectronique de l'environnement d'un véhicule. Certains véhicules sont déjà équipés de systèmes de détection de l'environnement reposant sur l'utilisation de caméras. Cependant, le design initial du véhicule est modifié lorsque des caméras de ce type sont installées sur des véhicules. La présente invention concerne donc un miroir (6) permettant la détection optoélectronique de l'environnement d'un véhicule. Ce miroir (6) réfléchit le rayonnement optique, de sorte que ce rayonnement, une fois réfléchi, se diffuse en direction de la puce optique intelligente. A cet effet, ledit miroir (6) présente un moyen de fixation (7) prévu pour être installé sur l'enveloppe externe du véhicule ainsi que sur des pièces rapportées (1) du véhicule. Grâce à cette conception modulaire, ce dispositif de détection de l'environnement peut être intégré à un véhicule en toute simplicité, le design initial du véhicule restant presque inchangé.
