Abstract

A tire characteristic receiver comprises a receiver circuit, a processing circuit, and a housing. The receiver circuit is configured to receive tire characteristic data wirelessly from a vehicle tire. The processing circuit is configured to receive the tire characteristic data and to provide the tire characteristic data to an operator interface device. The housing is coupled to the processing circuit and the receiver circuit and is removably coupleable to a vehicle interior element.

Claims

1. A tire characteristic receiver, comprising:

a receiver circuit configured to receive tire characteristic data wirelessly from a vehicle tire;

a processing circuit configured to receive the tire characteristic data and to provide the tire characteristic data to an operator interface device; and

a housing coupled to the processing circuit and the receiver circuit, wherein the housing is removably coupleable to a vehicle interior element.

2. The tire characteristic receiver of claim 1, wherein the housing includes an interface circuit configured to be coupled to a detector mounted to the vehicle.

3. The tire characteristic receiver of claim 2, wherein the interface circuit is configured to receive vehicle power from the vehicle, the tire characteristic receiver further comprising a power circuit configured to provide power to the receiver circuit from the vehicle power.

4. The tire characteristic receiver of claim 3, further comprising a rechargeable battery configured to provide power to the receiver circuit, wherein the power circuit is configured to recharge the battery from the vehicle power.

5. The tire characteristic receiver of claim 1, wherein the operator interface device includes a speaker configured to provide an audible message indicating the tire pressure.

6. The tire characteristic receiver of claim 1, wherein the housing is removable from the vehicle only in response to an operator-actuated switch.

7. The tire characteristic receiver of claim 1, wherein the processing circuit is configured to identify a vehicle tire nearest to the housing based on the tire characteristic data and without operator input.

8. The tire characteristic receiver of claim 1, wherein the tire characteristic data represents tire pressure.

9. The tire characteristic receiver of claim 1, wherein the receiver circuit is configured to receive the tire characteristic data in the radio frequency range.

10. The tire characteristic receiver of claim 1, wherein the housing completely encloses the receiver circuit and processor circuit.

11. The tire characteristic receiver of claim 1, wherein the housing is configured for coupling to an instrument panel of the vehicle.

12. The tire characteristic receiver of claim 1, wherein the receiver circuit and processing circuit are configured to receive a wireless message, record characteristics of the wireless message, and transmit a wireless signal based on the recorded characteristics.

13. The tire characteristic receiver of claim 1, wherein the housing encompasses a volume of less than 1000 cubic inches.

14. The tire characteristic receiver of claim 1, wherein the receiver circuit is configured to receive a remote keyless entry signal and the processing circuit is configured to operate a vehicle system based on data from the remote keyless entry signal.

15. The tire characteristic receiver of claim 14, wherein the vehicle system is a door lock.

16. A tire pressure monitor, comprising:
