Embodiment Construction

[0032] Such as figure 1 As shown, the protective device 1 according to the prior art, ie the radome, is intended to be arranged in front of the radar 2 . Radome 1 comprises at least one transmissive region 3 through which waves 4 of radar 2 can pass. The transmissive area 3 is formed of a material transparent to radar waves. The radome 1 can be fixed on the bumper of the motor vehicle, in front of the radar.

[0033] figure 2 The radome 1 is shown as a non-limiting example on the front face of the vehicle 10 .

[0034] image 3 A radome 1 according to one embodiment of the invention is shown. The protection device 1 for the radar 2 of the motor vehicle 10 comprises a body 200 formed of a material transparent to both radar waves 4 and light, two light sources 300 and a light reflector 400 formed of a material transparent to the radar waves 4 . These elements are arranged such that the light beam 500 emitted by the light source 300 is reflected by the light reflector 400 ...

Abstract

The invention relates to a radar (2) protection device (1) for a motor vehicle (10). The radar protection device comprises a body (200) made of a material that is transparent to both radar waves (4) and light, a light source (300), and a light reflector (400) made of a material that is transparent to the radar waves (4), which are arranged such that a light beam (500) emitted by the light source (300) is reflected by the light reflector (400) towards the body (200) made of transparent material.

Description

technical field [0001] The present invention relates to the field of motor vehicles equipped with radars and, more particularly, to the field of devices (also called "radomes") for obscuring and protecting such radars. [0002] The device according to the invention applies in particular to radars arranged in the front or rear bumper of a vehicle, for example of the ACC type. Background technique [0003] In particular for safety reasons, it is known to equip motor vehicles with radars of the ACC (expressed in English as “Adaptive Cruise Control”) type, for example. Such radars are used in particular to regulate the speed of the vehicle according to traffic and / or obstacles on the road. Radar detects the speed and distance of objects in front of the vehicle carrying it, especially in order to maintain a safe distance between vehicles. [0004] The ACC radar is mounted at the front or rear face of the vehicle, typically between the bars of the grille (which may be a cooling ...
