Abstract

A method and system for managing tire pressure in a vehicle is disclosed. The system is a tire pressure monitoring system associated with the tire pressure sensors. The method includes the general steps of informing the operator that air pressure in a tire is below a desired level, causing the sensor to undertake a rapid sampling of pressure of the tire during an interim state while the vehicle is being driven, advising the operator to manually add pressure to the tire in discrete increments of, for example, between 5 and 10 seconds, causing the sensor to undertake a rapid sampling of tire pressure while air is being manually added to the tire, and causing the sensor to transmit tire air pressure data until the operator stops adding air. The method may also include the step of providing the operator with feedback when a predetermined tire air pressure is reached.

Claims

1. A method for managing tire pressure in a vehicle, the method comprising:

forming a tire pressure monitoring system having a tire fill detection mode, said system including an air pressure sensor operatively associated with a tire;

informing the operator that air pressure in said tire is below a desired level;

causing said sensor to undertake a rapid sampling of pressure of said tire during an interim state while the vehicle is being driven;

advising the operator to manually add pressure to said tire in discrete increments;

causing said sensor to undertake a rapid sampling of tire pressure while air is being manually added to said tire; and

causing said sensor to transmit tire air pressure data until the operator stops adding air.

2. The method for managing tire pressure of claim 1 including the step of providing the operator with feedback when a predetermined tire air pressure is reached.

3. The method for managing tire pressure of claim 2 including the step of causing said sensor to transmit the last sampled value when said sensor detects no more air is being added.

4. The method for managing tire pressure of claim 3 wherein said step of causing said sensor to transmit the last sampled value when said sensor detects no more air is being added occurs while said system is in said tire fill detection mode.

5. The method for managing tire pressure of claim 4 wherein said discrete increments are between 5 and 10 seconds.

6. The method for managing tire pressure of claim 4 wherein said feedback is selected from the group consisting of an audio alert and a visual alert.

7. The method for managing tire pressure of claim 1 including the step of causing said sensor to transmit data when said sensor senses a pressure level that is above a predetermined threshold.

8. The method for managing tire pressure of claim 7 wherein said step of causing said sensor to transmit data when said sensor senses a pressure level that is above a predetermined threshold occurs while said system is in said tire fill detection mode.

9. The method for managing tire pressure of claim 8 wherein said discrete increments are between 5 and 10 seconds.

10. The method for managing tire pressure of claim 8 wherein said feedback is selected from the group consisting of an audio alert and a visual alert.

11. A method for managing tire pressure in a vehicle, the method comprising:

forming a tire pressure monitoring system, said system including an air pressure sensor operatively associated with a tire;

informing the operator that air pressure in said tire is below a desired level;

advising the operator to manually add pressure to said tire in discrete increments;

undertaking a rapid sampling of tire pressure while air is being manually added to said tire; and

transmitting tire air pressure data until the operator stops adding air.

12. The method for managing tire pressure in a vehicle of claim 11, including the step of undertaking a rapid sampling of pressure of said tire while the vehicle is being driven.

13. The method for managing tire pressure in a vehicle of claim 11, including the step of providing the operator with feedback when a predetermined tire air pressure is reached.

14. The method for managing tire pressure of claim 11 including the step of causing said sensor to transmit the last sampled value when said sensor detects no more air is being added.

15. The method for managing tire pressure of claim 14 wherein said step of causing said sensor to transmit the last sampled value when said sensor detects no more air is being added occurs while said system is in said tire fill detection mode.

16. The method for managing tire pressure of claim 11 including the step of causing said sensor to transmit data when said sensor senses a pressure level that is above a predetermined threshold.

17. The method for managing tire pressure of claim 16 wherein said step of causing said sensor to transmit data when said sensor senses a pressure level that is above a predetermined threshold occurs while said system is in said tire fill detection mode.

18. A tire pressure monitoring system for a vehicle, the system comprising:

a central processing unit;

a sensor operatively associated with said central processing unit and a vehicle tire, said sensor including a rapid sampling feature; and

a feedback notification unit.

19. The tire pressure monitoring system for a vehicle of claim 18 wherein said central processing unit includes a tire fill detection mode.

20. The tire pressure monitoring system for a vehicle of claim 18 wherein said feedback notification unit includes notification selected from the group consisting of an audio alert and a visual alert.
