Arrangement having a trim component and a radar sensor, motor vehicle and method for manufacturing an arrangement

摘要

An arrangement for a motor vehicle having a trim component, in particular a bumper, and a radar sensor is disclosed. In order to detect target objects, the radar sensor is designed to emit electromagnetic waves through the trim component and to receive radiation echoes from the target objects. The radar sensor has an azimuthal detection angle, by which a field of vision of the radar sensor in the azimuthal direction is defined, and is arranged at a distance from a rear side of the trim component, with the result that the azimuthal field of vision of the radar sensor intersects the trim component in an intersection region. In order to absorb interference waves outside the azimuthal detection angle an absorptive material is applied outside the intersection region in the azimuthal direction to the rear side of the trim component, where the intersection region is free of absorptive material.

1. An arrangement for a motor vehicle comprising:
a trim component comprising a bumper; and a radar sensor, which, in order to detect target objects, is designed to emit electromagnetic waves through the trim component and to receive radiation echoes from the target objects, wherein the radar sensor has an azimuthal detection angle, by which a field of vision of the radar sensor in the azimuthal direction is defined, and wherein the radar sensor is arranged at a distance from a rear side of the trim component, with the result that the azimuthal field of vision of the radar sensor intersects the trim component in an intersection region, wherein, in order to absorb interference waves outside the azimuthal detection angle, an absorptive material is applied outside the intersection region in the azimuthal direction to the rear side of the trim component, and the intersection region is free of absorptive material, and wherein the arrangement further comprises an absorptive element for absorbing the interference waves, wherein the absorptive element bears on an edge region of a raydome of the radar sensor and on the absorptive material.
