Abstract

A method and system of teaching identification codes for a tire pressure monitoring system includes the steps of transmitting a prompt signal that includes a location identifier. This prompt signal instructs the tire pressure monitoring sensor to transmit an initialization signal. The initialization signal includes the location identifier. A factory receiver is set up to recognize transmissions that include a corresponding location identifier. The receiver disregards all other transmissions that do not include the corresponding desired location identifier.

Claims

1. A method of teaching an identifier for a remote device to a corresponding receiver comprising the steps of:

a) transmitting a prompt signal to a remote device, where the transmission prompt communicates an identifier to the remote device;

b) transmitting an initialization signal from the remote device that includes the identifier; and

c) selectively receiving the initialization signal with a receiver responsive to the identifier corresponding with signals the receiver is set to recognize.

2. The method as recited in claim 1, wherein the identifier comprises a location identifier indicative of a location of the sensor.

3. The method as recited in claim 2, including the step of reading the location identifier and recording an identification code responsive to the receiver recognizing the location identifier.

4. The method as recited in claim 1, wherein the identifier comprise a unique frequency and the initialization signal is transmitted at the unique frequency.

5. The method as recited in claim 4, wherein the receiver is set to recognize transmissions only on the unique frequency.

6. The method as recited in claim 1, including more than one receiver and more than one identifier corresponding with the more than one receivers.

7. A method of teaching an identification code of a tire pressure monitoring sensor comprising the steps of:

a) transmitting a prompt signal including an identifier to a tire pressure monitoring sensor;

b) transmitting an initialization signal from the tire pressure monitoring sensor including the identifier received in the prompt signal; and

c) selectively receiving the initialization signal with a receiver responsive to the receiver recognizing the identifier.

8. The method as recited in claim 7, wherein the identifier comprise a code indicative of a location of the tire pressure sensor.

9. The method as recited in claim 8, wherein the receiver is associated with the code indicative of location and recognizes initialization signals only including the code indicative of a location of the tire pressure sensor corresponding to the receiver.

10. The method as recited in claim 9, including at least two receivers each set to receive an initialization signal of a common frequency.

11. The method as recited in claim 10, wherein each of the at least two receivers corresponds to a different location and is set to receive a different code indicative of location.

12. The method as recited in claim 7, wherein the identifier comprises a specific frequency and the tire pressure monitoring sensor transmits the initialization signal as the specific frequency.

13. The method as recited in claim 12, including more than one receiver, only one of which is set to receives the specific frequency.

14. The method as recited in claim 12, wherein each of the more than one receivers are set to receive a frequency different than all of the other receivers.

15. A system for communicating tire pressure monitoring identities to a receiver comprising:

a transmitter for transmitting a prompt signal to a tire pressure sensor, where the prompt signal instructs the tire pressure monitoring sensor to transmit an initialization signal including a location identifier; and

a receiver corresponding to the transmitter for receiving initialization signals only including a corresponding location identifier.

16. The system as recited in claim 15, comprising at least two transmitters and a corresponding receiver each corresponding to a desired location.

17. The system as recited in claim 15, wherein the location identifier comprises a frequency.

18. The system as recited in claim 17, wherein the tire pressure monitoring sensor includes a transmitter for transmitting at more than one frequency, where the transmitter transmits the initialization signal at the frequency instructed by the transmitter.

19. The system as recited in claim 18, wherein each of the at least two receivers receives signal of a frequency different than all the other receivers.

20. The system as recited in claim 15, wherein the location identifier includes a code sent with the initialization signal.

21. The system as recited in claim 20, wherein the receiver recognizes only those signals including a code corresponding to a location of the receiver.
