Abstract

L'invention concerne un dispositif de détection de collision pour un véhicule, le dispositif comprenant : un absorbeur de pare-chocs (2) qui est disposé à l'intérieur d'un pare-chocs (7) du véhicule et sur le côté avant du véhicule d'un renfort de pare-chocs (9); un élément tubulaire de détection (3) qui est monté dans une section de rainure (2a) formée dans l'absorbeur de pare-chocs dans le sens de la largeur du véhicule, et à l'intérieur duquel est formée une section creuse (3a); et un capteur de pression (4) qui détecte la pression dans la section creuse de l'élément tubulaire de détection. Le dispositif de détection de collision pour un véhicule détecte la collision d'un objet avec le pare-chocs sur la base de résultats de détection de pression émis par le capteur de pression. Le dispositif de détection de collision pour un véhicule est pourvu d'au moins un élément périphérique externe (31) qui est disposé au niveau d'une position prédéfinie sur l'élément tubulaire de détection dans le sens de la largeur du véhicule, qui recouvre la surface périphérique externe de l'élément tubulaire de détection sur au moins le côté supérieur ou le côté inférieur par rapport au véhicule, et qui est plus rigide que l'élément tubulaire de détection.
