Abstract

A system and method for remote monitoring of tire pressure in a vehicle having multiple tires includes a controller mounted on the vehicle and provided in communication with a vehicle radio. The vehicle radio is for use in receiving wireless broadcast signals and includes a display. The controller generates tire information signals based on tire pressure data transmitted from each of the tires. The tire information signals are used by the vehicle radio to convey tire pressure information to a vehicle occupant using the vehicle radio display.

Claims

1. A system for remote monitoring of tire pressure in a vehicle having a plurality of tires, the system comprising:

a plurality of transmitters, each transmitter for mounting in one of the plurality of tires and for transmitting tire pressure data; and

a controller for mounting on the vehicle, the controller to be provided in communication with a vehicle radio for use in receiving wireless broadcast signals, the vehicle radio having a display, wherein the controller generates tire information signals based on the tire pressure data, the tire information signals for use by the vehicle radio to convey tire pressure information to a vehicle occupant using the display.

2. The system of claim 1 wherein the transmitters are also for transmitting tire temperature data, the controller generates tire information signals based on the tire temperature data, and the tire information signals are for use by the vehicle radio to convey tire temperature information to the vehicle occupant using the display.

3. The system of claim 1 wherein the tire information signals are for use by the vehicle radio to convey tire location information to the vehicle occupant using the display.

4. The system of claim 1 further comprising a receiver for mounting on the vehicle, the receiver to be provided in communication with the controller and for receiving the tire pressure data transmitted by the transmitters.

5. The system of claim 2 further comprising a receiver for mounting on the vehicle, the receiver to be provided in communication with the controller and for receiving the tire pressure and temperature data transmitted by the transmitters.

6. The system of claim 1 wherein the radio comprises a receiver for receiving the tire pressure data transmitted by the transmitters.

7. The system of claim 2 wherein the radio comprises a receiver for receiving the tire pressure and temperature data transmitted by the transmitters.

8. The system of claim 1 wherein the radio has at least one speaker associated therewith, and the tire information signals are for use by the vehicle radio to convey tire pressure information to the vehicle occupant using the at least one speaker.

9. The system of claim 2 wherein the radio has at least one speaker associated therewith, and the tire information signals are for use by the vehicle radio to convey tire pressure and temperature information to the vehicle occupant using the at least one speaker.

10. The system of claim 8 wherein the tire information signals are for use by the vehicle radio to convey tire location information to the vehicle occupant using the at least one speaker.

11. The system of claim 1 wherein the controller is provided in communication with the vehicle radio over a data bus.

12. The system of claim 1 wherein the controller is provided in communication with the vehicle radio over a data bus, and the controller converts the tire temperature data to the tire information signal for transmission to the vehicle radio over the data bus.

13. A method for remote monitoring of tire pressure in a vehicle having a plurality of tires, the method comprising providing a controller for mounting on the vehicle, the controller to be provided in communication with a vehicle radio for use in receiving wireless broadcast signals, the vehicle radio having a display, wherein the controller generates tire information signals based on tire pressure data transmitted from each of the plurality of tires, the tire information signals for use by the vehicle radio to convey tire pressure information to a vehicle occupant using the display.

14. The method of claim 13 further comprising providing a plurality of transmitters, each transmitter for mounting in one of the plurality of tires and for transmitting tire pressure data.

15. The method of claim 14 wherein the transmitters are also for transmitting tire temperature data, the controller generates tire information signals based on the tire temperature data, and the tire information signals are for use by the vehicle radio to convey tire temperature information to the vehicle occupant using the display.

16. The method of claim 13 wherein the tire information signals are for use by the vehicle radio to convey tire location information to the vehicle occupant using the display.

17. The method of claim 13 further comprising providing a receiver for mounting on the vehicle, the receiver to be provided in communication with the controller and for receiving the tire pressure data transmitted by the transmitters.

18. The method of claim 15 further comprising a receiver for mounting on the vehicle, the receiver to be provided in communication with the controller and for receiving the tire pressure and temperature data transmitted by the transmitters.

19. The method of claim 13 wherein the radio comprises a receiver for receiving the tire pressure data transmitted by the transmitters.

20. The method of claim 15 wherein the radio comprises a receiver for receiving the tire pressure and temperature data transmitted by the transmitters.

21. The method of claim 13 wherein the radio has at least one speaker associated therewith, and the tire information signals are for use by the vehicle radio to convey tire pressure information to the vehicle occupant using the at least one speaker.

22. The method of claim 15 wherein the radio has at least one speaker associated therewith, and the tire information signals are for use by the vehicle radio to convey tire pressure and temperature information to the vehicle occupant using the at least one speaker.

23. The method of claim 21 wherein the tire information signals are for use by the vehicle radio to convey tire location information to the vehicle occupant using the at least one speaker.

24. The method of claim 13 wherein the controller is provided in communication with the vehicle radio over a data bus.

25. The method of claim 13 wherein the controller is provided in communication with the vehicle radio over a data bus, and the controller converts the tire temperature data to the tire information signal for transmission to the vehicle radio over the data bus.
