Abstract

Pour surveiller l'état de fonctionnement d'un radar (10) monté sous une traverse avant (4) de véhicule, le radar comportant une position normale permettant de détecter des obstacles fixes ou mobiles à l'avant du véhicule, le dispositif comprend un capteur (5) agencé pour signaler un déplacement du radar (10) par rapport à sa position normale, ledit déplacement risquant d'occulter un obstacle pour lequel un freinage du véhicule s'impose.To monitor the operating condition of a radar (10) mounted under a front cross member (4) of a vehicle, the radar having a normal position for detecting fixed or moving obstacles in front of the vehicle, the device comprises a sensor (5) arranged to signal a movement of the radar (10) relative to its normal position, said movement running the risk of obscuring an obstacle for which braking of the vehicle is required.
