Abstract

Device for vehicle identification, comprising a license plate for a vehicle, wherein the license plate is made of electrically conductive material and provided with a transponder, particularly an RFID chip, wherein the transponder with both connections is electrically coupled to the material of the license plate and wherein the license plate is provided with a slot-shaped recess, wherein both connections at opposite sides of the slot-shaped recess are coupled to the license plate.

Claims

1. Device for vehicle identification, comprising a license plate for a vehicle, wherein the license plate is at least partially made of electrically conductive material and provided with a transponder, particularly an RFID chip, wherein the transponder is electrically coupled to the material of the license plate.

2. Device according to claim 1, wherein the transponder with its ground connection is electrically coupled to the material of the license plate.

3. Device according to claim 1, wherein the transponder with both connections is electrically coupled to the material of the license plate.

4. Device according to claim 3, wherein the license plate is provided with a recess, wherein the connections are electrically coupled on both sides of the recess to the material of the license plate.

5. Device according to claim 4, wherein the recess is elongated, particularly slot-shaped.

6. Device according to claim 4, wherein the recess is bounded by a circumferential edge.

7. Device according to claim 4, wherein the transponder is situated at the location of the recess.

8. Device according to claim 7, wherein the transponder is situated in the recess.

9. Device according to claim 4, wherein the transponder is spaced apart from one end of the slot-shaped recess.

10. Device according to claim 9, wherein the recess is slot-shaped and the transponder is situated halfway the length of the slot-shaped recess.

11. Device according to claim 9, wherein the recess is slot-shaped and the transponder in longitudinal direction of the slot-shaped recess is situated outside of the centre of the length of the slot-shaped recess.

12. Device according to claim 1, wherein the transponder is directly electrically coupled to the material of the license plate.

14. Vehicle provided with a device/license plate according to claim 1.

15. Identification system for vehicles, wherein vehicles are provided with devices according to claim 1, wherein the system

13. License plate for a vehicle, wherein the license plate comprises a transponder, such as an RFID chip, that is electrically connected to an electrically conductive part of the license plate that is adapted to be an antenna to the transponder.

16. Method for identifying a vehicle, comprising the following steps:

transmitting a radio signal to the vehicle;

receiving the radio signal by means of a license plate of the vehicle, wherein the license plate is at least partially made of an electrically conductive material, and is adapted to be a reception antenna;

transferring the radio signal from the license plate to a transponder, particularly an RFID chip, wherein the transponder is electrically coupled to the material of the license plate.

17. Method according to claim 16, further comprising the step of the transponder transmitting an identification signal in response to the received radio signal.

18. Method according to claim 16, further comprising the following steps:

the transponder creating an identification signal in response to the received radio signal;

transferring the identification signal from the transponder to the license plate, which is adapted to be a transmitting antenna for transmission of the identification signal.
