Definitions

  • the invention relates to a device for the detection and evaluation of objects in the area surrounding a vehicle according to the preamble of patent claim 1.
  • a device for detecting and evaluating objects in the area surrounding a vehicle of the generic type is known from DE 199 63 005 AI of the applicant. It comprises a pulse radar sensor with transmitting and receiving means for transmitting and receiving electromagnetic waves in the gigahertz range. The electromagnetic waves are emitted and received by an antenna.
  • a so-called radome is usually provided for protection against damaging environmental influences in antennas of this type.
  • the artificial word radome denotes a spherical protective dome. In this application, radome is also used to refer to protective agents that are not spherical.
  • the invention offers the advantages that the design of the radome enables beam shaping, in particular beam broadening and / or beam swiveling.
  • Beam broadening in a horizontal plane serves to expand the detection area to an extent that would not be possible with a conventional radome.
  • a beam swivel enables easy adaptation to the body shape of the respective vehicle and thus offers greater flexibility when installing the device.
  • Most of the components of the device can consist of identical parts that can be manufactured in large series.
  • the adaptation to the radiation characteristic required for a specific vehicle type is then carried out by the radomes designed according to the invention.
  • the radomes can be connected to the device by means of a clip connection, particularly in terms of installation.
  • FIG. 1 shows the device with its essential assemblies in an exploded view
  • FIG. 2 shows a cross section through the device with a first embodiment of a radome
  • FIG. 3 shows a cross section through the device with a second embodiment of a radome
  • FIG. 5 shows a cross-section through the device with a fourth embodiment of a radome
  • FIG. 6 shows a top view of a strip-shaped radome. Description of the embodiments
  • Fig.l shows the device 1 with its essential assemblies in an exploded view.
  • the device 1 comprises a trough-shaped housing 10, 15 with a housing trough 10 and a cover 15.
  • the further assemblies 11a, 11b and 12 are mounted in the housing trough which is closed with the cover 15 after the assembly of these assemblies.
  • recesses in the bottom of the housing trough 10 are designated. These recesses are slit-shaped and extend parallel to one another in opposite regions of the bottom of the housing trough 10. The electromagnetic energy is radiated through these slit-shaped recesses 10a, 10b.
  • 11a, 11b radomes are designated.
  • radomes are essentially strip-shaped and can be inserted into the housing trough 10 such that they cover the slot-shaped recesses 10a, 10b in the bottom of the housing trough. They thus close off the housing 10, 15 in the bottom area thereof and consequently take over the usual protective function of a radome, which shields sensitive high-frequency components against harmful environmental influences.
  • the radomes 11a, 11b can be connected particularly advantageously by means of a clip connection to the housing trough 10 or else to the further assemblies 12. This considerably simplifies and simplifies the assembly of the device 1.
  • the radomes 11a, 11b are designed such that they not only fulfill the protective function known from conventional radomes, but also also effect beam shaping and / or beam deflection. This is explained in the following using several exemplary embodiments described. 2, 3, 4 and 5 each show a cross section through the device 1 along a recess 10a, 10b in the bottom of the housing trough 10.
  • the exemplary embodiment illustrated in FIG. 2 illustrates in principle how that into the housing trough 10 inserted radome 11a covers the recess 10a in the bottom of the housing trough 10 and thus seals the housing 10, 15 against the environment.
  • the radome 11a can be particularly advantageously clipped onto carriers 21a, 21b, 21c, 21d, which are connected to the circuit board 12.
  • the radome 11a which is essentially in the form of a strip can expediently additionally be provided with spacers 20a, 20b which preferably extend perpendicularly to a main surface of the radome 11a.
  • the radome 11a is preferably made of a material which is well permeable to high-frequency radiation in the gigahertz range, but is weatherproof, since it is exposed to harsh environmental conditions in the everyday operation of a vehicle.
  • a thermoplastic, in particular PBT (polybutylene terephthalate) has proven particularly suitable.
  • the thickness D of the radome 11a, 11b in the area of the recesses 10a, 10b is reduced as much as the mechanical stability and manufacturing technology allow.
  • a thickness D of the radome 11a, 11b between 0.2 mm and 15 mm can be considered.
  • a particularly favorable compromise with regard to a low damping value and still sufficient mechanical stability is a thickness D of the radome 11a, 11b of 1.0 mm.
  • a recess is made in the outer surface of the radome 11a, 11b, which reduces the thickness D of the radome in this area as desired.
  • recesses are particularly simple realize that are rotationally symmetrical so that the surface of the recess has the shape of a spherical section or a spherical layer, for example.
  • the shape of the recess serves to influence the beam, in particular for beam shaping and / or beam deflection of the emitted electromagnetic energy.
  • the recess is of cylindrical symmetry, that is to say that the outer surface of the recess is part of a cylindrical surface.
  • the radome 11a, 11b acts as a cylindrical lens, which enables beam broadening in a horizontal plane. This enables a particularly favorable expansion of the detection area.
  • the recess has the shape of an asymmetrically designed cylindrical lens. Beam deflection or beam swiveling can thereby be achieved in a simple manner. This in turn allows the radiation characteristics of the device to be adapted particularly easily to different vehicle body shapes. In this way there is great flexibility with regard to a favorable installation location for the device. It is of course within the scope of the inventive solution to also provide other lens shapes in connection with the radome 11a, 11b.
  • a radome 11a proves to be expedient, which, as shown in FIG has electromagnetic radiation in the sense of beam bundling and / or deflection regions 60.

Abstract

L'invention concerne un dispositif (1) destiné à détecter et à évaluer des objets situés dans la zone environnante d'un véhicule et comprenant des moyens d'émission et de réception d'un rayonnement électromagnétique de l'ordre du gigahertz. Ce dispositif détecte au moins une antenne protégée par un radôme (11a, 11b). Ce radôme (11a, 11b) a une forme lenticulaire de manière à permettre une focalisation du faisceau et/ou un balayage du faisceau du rayonnement électromagnétique émis.
