Definitions
- the invention relates to a device for mounting a sensor assembly on a motor vehicle, in particular a radar sensor with at least one detection range in the sensor direction according to the preamble of claim 1.
- WO 2006/005546 AI is a generic device for mounting a sensor assembly, in particular a radar sensor known behind a bumper of a
- Motor vehicle is arranged by means of a sensor assembly at least partially surrounding sleeve as a molded part, wherein the sleeve consists of a radar absorbing material.
- this cuff also serves to largely prevent dirt, moisture and particle deposits on the sensor assembly.
- this known cuff can be made of flexible material to reduce or cushion mechanical stresses on the sensor assembly that may occur during normal and proper use as well as in the case of less severe collisions and to prevent the buildup of mechanical vibration.
- this known Man- serve as a sensor holder.
- CONFIRMATION COPY Object of this invention is therefore to develop a device for mounting a sensor assembly behind an attachment of a motor vehicle of the type mentioned in such a way that an optimal mechanical protection of the sensor assembly is achieved.
- This object is achieved by a device with the Merkmaien of claim 1
- the molded part is formed in the detection range of the sensor assembly permeable to the sensor signals
- the molding on the accessory side has a surface which is shaped to be complementary to the surface of the vehicle attachment and rests against the same surface-locking.
- a transmission beam generated by the sensor module is formed by means of optical element elements arranged in the molded part.
- the sensor assembly has a main radiation region for a transmission beam generated by it and secondary radiation regions are generated by reflection on at least one reflector element arranged in the molded part.
- a waveguide structure extending from the sensor assembly to the vehicle attachment is integrated in the molded part, which can be resonantly designed and autoclaved over a defined overall length so that a contamination blockage can be detected.
- the molding is elastically deformable and has mechanical damping properties, ie. is formed with a vibration-damping or energy-absorbing material property.
- This vibration and shock loads of Sen- Sor assembly, in particular mechanical effects of the sub-component on the sensor assembly significantly improved.
- the molded part and the sensor assembly can be mounted by means of a mechanical device to the vehicle body.
- the vehicle attachment in particular the bumper is in the detection range of the sensor module permeable to the sensor signals.
- This device according to the invention is particularly suitable as a radar sensor assembly for automotive applications.
- This figure 1 shows a vertical Thomasdar Beneficiung a mounted behind a bumper 2 of a Kraftf ra ra darsensors 1 as an embodiment of the invention.
- an elastic and massi ves molded part 3 is provided, for example. From foamed Plastic is produced and radar radiation only slightly attenuates.
- This molded part 3 has a pocket-shaped receptacle 3b with an inner contour adapted to the shape of the radar sensor assembly 1. As a result, this radar sensor 1 is almost completely enclosed, ie both in the x direction
- a latching lug 3c formed on the circumferential edge of the pocket-shaped receptacle 3b is integrally formed, so that the radar sensor 1 can be clipped into this receptacle 3b, whereby a simple assembly is achieved. Furthermore, a fastening sensor 1 with the body structure is provided.
- the mounting-side surface 3a of the molded part 3 is formed complementarily to the opposite inner surface 2a of the bumper 2, so that the two surfaces 3a and 3b are flush with each other. This prevents dirt, ice or snow from depositing between the molded part 3 and the bumper 2.
- a local swinging of the bumper 2 is prevented by this good fit between the molding 3 and bumper 2, whereby the radar sensor 1 is protected against mechanical action of the bumper 2, so that due to the minimization of vibrations in the bumper 2 a high signal quality of the radar sensor. 1 is achieved.
- the molded part 3 When producing the molded part 3 from a foamed plastic whose filling factor is set so that a minimum transmission loss of a few tenths of decibels in the propagation direction (x-direction) of the radar beams is achieved. For example, meet this requirement foams on polyethylene or polyurethane-based.
- the free surface 4 of the molded part 3 is hydrophobic, for example. Designed as a liquid and moisture-repellent coating.
- absorbent admixtures in the form of graphite particles or ferromagnetic absorber materials as absorbers 5, which are produced, for example, in a two-component injection molding process.
- the frequently occurring parasitic radiation is effectively absorbed by surface waves and / or leakage radiation at antenna elements of the radar sensor 1.
- Such shielding effectively contributes to significantly reducing the generation of secondary lobes in the antenna pattern and the likelihood of misdetection of objects by the radar sensor 1.
- the molded part 3 contains in the detection range of the radar sensor 1 optical lens elements 6 for beam shaping in Nah- and
- these lens elements 6 are made of dielectric material. Also, the introduction of local periodic structures in the form of material geometries (Photonic Band Gaps (PBG), Electromagnetic Band Gap (EBG), Frequency Selective Surfaces (FFS)) can cause beam shaping in the near and far range and to absorption of surface waves and leakage radiation contribute.
- PBG Photonic Band Gaps
- ECG Electromagnetic Band Gap
- FFS Frequency Selective Surfaces
- a waveguide structure 8 extending from the radar sensor 1 to the bumper 2 of the motor vehicle can be integrated in the molded part 3.
- line properties eg amplitudes and phase relationships
- the state of the line Bumper 2 eg in case of dirt, ice / snow cover, etc.
- the ascertained state parame- ters are used to detect a possible Sensor blockage and autocalibration of the sensor parameters such as sensor power, noise behavior, etc. As a result, degradation effects of the sensor can be detected and recalibrated over its service life.
- Reflector elements 7 in addition the beam shaping and Er-
- Reflector elements 7 are integrated for calibration purposes in the molded part 3.
- the device according to the invention for mounting the radar sensor by means of a molded part reliably protects against contamination, prevents deposits between the radar sensor and the bumper of Kraftf hrzeugs and realizes a protective function against vibration and shock loads.
- the molding functional elements such as
- Absorber elements, optical lens elements, waveguide structure and reflector elements optimized the antenna performance and - characteristic (directivity).
