Definitions

  • the present invention proposes a transponder system for a vehicle.
  • the electronic key which is a chip card or similar Device typically includes a transponder that is inside this specific area can or will be excited by the on-board electronics.
  • the on-board electronics include a transceiver system, which is designed in this way is that it creates a magnetic field, which is the transponder of the key excited.
  • the transceiver and the key are then able to Exchange security identifiers that can be used to determine whether access should be allowed to the key wearer.
  • the transceivers contain antennas, in particular one Dual antenna can be contained in a transceiver housing.
  • Transceivers with double antennas are located at a suitable point in the vehicle, such as. in the rearview mirror unit.
  • the magnetic field which is generated by the antennas of the transceiver, often has a comparatively limited range, which in certain cases does this lead that the key transponder is not excited when the Transponder is oriented differently than the double antennas.
  • Considerable losses were observed with double antennas, whereby it is assumed that the field generated by the two antennas is an extinguishing one Effect on the field of the other antenna.
  • One of the antennas needed possibly a ferrite core, so that the performance is increased accordingly. It will wanted to alleviate these problems or at least be a useful alternative to offer.
  • the present invention proposes a transponder system for a vehicle, which contains a transceiver with at least two antennas, each Antenna defines an antenna direction, characterized in that the Antennas are mounted separately in the vehicle, with the directions the antennas are substantially perpendicular to each other.
  • a transponder system for a vehicle contains a Transceiver system 2, which has a housing 4, which the entire Electronics 6 for exciting a transponder in a remote electronic Contains key.
  • the transceiver housing can in certain cases existing components of the vehicle are not visibly installed, for Example in the rear view mirror unit or in a rear door handle.
  • the transceiver housing 4 contains the first antenna 10.
  • the antenna 10 can have its own separate housing.
  • the Antenna 10 can be in the rearview mirror unit or in a rear door handle be installed while the transceiver housing is attached to the body is.
  • the antenna 10 includes a wire coil 12 and a resistor 13.
  • the Sie is used to generate a magnetic field to excite the transponder Generating keys.
  • the antenna coil 12 is arranged so that it is a Antenna or field direction, as indicated by arrow 14.
  • the transceiver can either be constantly active or it is activated by the Controlled on-board electronics of the vehicle and asked to close the transponder irritate.
  • the on-board electronics can control the transceiver, for example, when it is detected that a door handle has been moved. As soon as the key is energized he communicates with the transceiver for security identifiers to exchange which are used to determine whether access authorization exists.
  • the transceiver 2 also contains two connecting wires 16 am Housing 4, to which a second antenna 18, which is located at a different location in the Vehicle is connected.
  • the second antenna 18 also contains a coil 20 and a resistor 22, the coil 20 sets an antenna or Field direction, as indicated by arrow 24.
  • the transceiver shows a clear performance gain of up to 20 to 30% compared to the known double antenna coils for vehicles.
  • the Range of the magnetic field generated by the antennas is increased itself essential, so the ability to place the transponder in a key can be located in different places to excite, significantly improved so that ferrite cores for the coils can be omitted.
  • the antennas 10 and 18 can be located at different locations, as shown in FIG. 2. For example, if the first antenna 10 in the transceiver housing 4 is in an exterior mirror unit 32 at the front of the vehicle, then the second antenna 18 could be in an adjacent front door handle 34, or alternatively nearby in a rubber or chrome trim strip, which is located on an outer panel of the vehicle 30, for example. If the first antenna 10 in the transceiver housing 4 is located in the rear of the vehicle, for example in a rear door handle 38, then the second antenna 18 can be mounted either in an adjacent rear wheel housing 40 or in the rear bumper 42. The first antenna 10 can also be in a trim strip 36 and the second antenna 18 either in an adjacent rear wheel arch 40 or * 1 in the rear bumper 42. The antennas 10 and 18 can also be located in the rear lights 44 and 46, respectively.
  • the antennas 10 and 18 are attached to the vehicle separately. In addition, they must be arranged so that together they are an elliptical polarized magnetic field to excite the key transponder produce. There is an optimal distance between antennas 10 and 18, which is large enough to avoid the wiping effect and small enough to ensure that the elliptical polarized magnetic field is produced. It depends on the materials and components used in the vehicle and keys are installed.
