Abstract

An integrated vehicle communications system for on-board use within a vehicle which may also communicate with external portions of the system which includes miniaturized, self-contained read/write transponders 20, 22, 30 of the type disclosed in Schuermann U.S. Pat. No. 5,053,774, for providing functions within the vehicle, e.g., for sensing conditions and parameters, The on-board interrogation unit 10 interrogates and receives signals by RF communication provided by on-board antennas 14, 26, 28 between the interrogation unit and respective transponders for read/write responder operation. The processor 33 with display device 34a and/or control circuits 34b carries out on-board functions in response to such interrogation. A transponder 22 may serve as a vehicle operator key by which the system may verify key code, unlock the vehicle doors, as well as select and perform initialization functions including ignition, seat and seat belt adjustment, mirror positioning, and antitheft functions before vehicle entry by the operator. A transponder 30 may access external control data for premises or toll access, and may provide toll or credit or service transactions, as for authorization or verification or toll charge debiting purposes. The system may include also IR links.

Claims

1. An integrated vehicle communications system for on-board use within a vehicle, the system comprising:

miniaturized, self-contained transponder means on-board said vehicle using radio frequency interrogation energy for the respective transponder operation and associated with a vehicle function;

interrogation means on-board the vehicle for interrogating and receiving signals from the transponder means;

means for providing RF communication between the interrogation means and the transponder means in response to interrogation operation of the interrogation means; and

means responsive to the interrogation means for carrying out on-board functions in response to such interrogation.

2. The integrated vehicle communications system of claim 1 wherein said transponder further includes means for accumulating said radio frequency energy as a source of power.

3. An integrated vehicle communications system as set forth in claim 1 and further comprising a key transponder for use by a vehicle operator to replace or supplement a conventional vehicle key for vehicle entry control, the means for providing RF communication provides for communication between the interrogation means and the key transponder for interrogation of the key transponder as the vehicle operator with the key transponder approaches the vehicle, and wherein the means responsive to the interrogation unit permits vehicle entry if the key transponder authorizes such entry.

4. An integrated vehicle communications system as set forth in claim 3 wherein said key transponder also serves as media for access to premises use other than vehicle entry.

5. An integrated vehicle communications system as set forth in claim 3 wherein the means responsive to the interrogation means in addition to permitting vehicle entry if the key transponder authorizes such entry selects and performs vehicle initialization functions, such as ignition, seat and seat belt adjustment, if the key transponder authorizes such entry.

6. An integrated vehicle communications system as set forth in claim 3 wherein the key transponder enables credit transactions with a facility external of the vehicle.

7. An integrated vehicle communications system as set forth in claim 3 wherein the key transponder is enabled to send safety alert functions to the car.

8. An integrated vehicle communications system as set forth in claim 1 wherein the transponder means and means for providing RF communication are adapted for enabling transactions with a facility external of the vehicle.

9. An integrated vehicle communications system as set forth in claim 8 wherein the transactions with a facility external of the vehicle are for toll authorization.

10. An integrated vehicle communications system as set forth in claim 9 wherein the transactions with a facility external of the vehicle are for premises authorization.

11. An integrated vehicle communications system as set forth in claim 8 wherein said transponder means is capable of reading from an external data source.

12. An integrated vehicle communications system as set forth in claim 1 wherein said transponder means provides communication to said interrogation means indicative that a part or component of said vehicle is present.

13. An integrated vehicle communications system as set forth in claim 1 wherein said transponder means is capable of reading from an on-board data source representative of the vehicle'"'"'s condition.

14. An integrated vehicle communications system as set forth in claim 13 wherein said condition is temperature.

15. An integrated vehicle communications system as set forth in claim 1 wherein said transponder can be read from and written to by said interrogation means.

16. An integrated vehicle communications system as set forth in claim 1 wherein said transponder is operated in read only mode such that said interrogation means reads from but does not write to said transponder means.

17. An integrated vehicle communications system for on-board use within a vehicle, the system comprising:

a plurality of miniaturized, self-contained read/write transponders on-board the vehicle, each capable of using energy of radio frequency interrogation as a source of power for a respective read/write transponder operation, and each associated with a vehicle function;

an interrogation means on-board the vehicle for interrogating and receiving signals from the respective transponders; and

means for providing RF communication between the interrogation means and each of the transponders for read/write responder operation by the transponders in response to interrogation operation of the interrogation means; and

means responsive to the interrogation means for carrying out on-board functions in response to such interrogation.

18. An integrated vehicle communications system as set forth in claim 17 wherein the means for providing RF communication between the interrogation means and each of the transponders comprises a multiplexer interconnected with the interrogation means and respective antenna connected with the multiplexer for RF communication with respective transponders.

19. The integrated vehicle communications system of claim 18 wherein said interrogation means includes a controller and further including a satellite interrogator controlled or activated by said controller.

20. An integrated vehicle communications system as set forth in claim 17 wherein the means responsive to the interrogation means for carrying out on-board functions in response to such interrogation comprises operator display means for displaying system information to the vehicle operator system information in display format to the operator in response to interrogation/responder operation.

21. An integrated vehicle communications system as set forth in claim 17 wherein the means responsive to the interrogation means for carrying out on-board functions in response to such interrogation comprises means for carrying out specific vehicle on-board functions, in response to interrogation/responder operation.

22. An integrated vehicle communications system as set forth in claim 17 and further comprising a key transponder to replace or supplement a conventional vehicle key for vehicle entry control.

23. An integrated vehicle communications system as set forth in claim 17 wherein one of the transponders and the means for providing RF communication are adapted for enabling transactions with a facility external of the vehicle.

24. An integrated vehicle communications system as set forth in claim 23 wherein the transactions with a facility external of the vehicle are for toll authorization.
