Abstract

A device for monitoring and adjusting tire pressure of a vehicle having a monitoring module and a computing module operatively coupled to the monitoring module. The monitoring module is configured to sense a tire pressure. Further, the monitoring module is configured to compare the sensed pressure with the low pressure limit value associated with the tire, to identify a low pressure condition. The computing module includes an interface module, configured to alert a user once the low pressure condition is identified and accept a new load value, and a processing module. The processing module is configured to generate a new tire pressure value based on the new load value, recommend the new tire pressure value to the user, and modify the tire pressure to the new tire pressure value upon a determination that the user accepts the new tire pressure value.

Claims

1. A device for monitoring the tire pressure of a vehicle, based on the vehicle'"'"'s load, the device comprising:

a monitoring module configured to;

sense a tire pressure; and

compare the sensed tire pressure with a low pressure limit value to identify a low pressure condition; and

a computing module operatively coupled to the monitoring module, including;

an interface module configured to;

alert upon identifying the low pressure condition; and

accept a new load value; and

a processing module operatively coupled to the interface module, configured to;

generate a new tire pressure value based on the new load value;

recommend the new tire pressure value; and

modify the pressure of the tire to the new tire pressure values upon acceptance of the new tire pressure value.

2. The device of claim 1, wherein the monitoring module comprises at least one pressure sensor to sense the pressure of the tire.

3. The device of claim 1, wherein the low pressure condition is identified when the pressure of the tire is lower than the low pressure limit value.

4. The device of claim 1, wherein the interface module is configured to accept the new load value upon a determination that pressure of the tire should be modified.

5. The device of claim 1, wherein the processing module provides the new tire pressure value to the interface module for acceptance.

6. The device of claim 1, wherein the interface module displays the new tire pressure value corresponding to the new load value.

7. The device of claim 1, wherein the processing module calculates a new low pressure limit value for the tire based on the new tire pressure value, upon modification of the tire pressure to the new tire pressure value.

8. The device of claim 1, wherein the tire is a rear tire of the vehicle.

9. The device of claim 1, wherein the tire is a front tire of the vehicle.

10. A method for monitoring the tire pressure of a tire for a vehicle, based on the vehicle'"'"'s load, the method comprising:

monitoring pressure of the tire;

comparing the monitored pressure with a low pressure limit value to identify a low pressure condition;

alerting upon identifying the low pressure condition;

accepting a new load value and calculating an appropriate new tire pressure value based on the new load value;

recommending the new tire pressure value; and

modifying the pressure of the tire to the new tire pressure value upon acceptance of the new tire pressure valuer.

11. The method of claim 10, wherein the modifying step further includes calculating a new low pressure limit value for the tire based on the new tire pressure value, upon modification of the tire pressure to the new tire pressure value.

12. The method of claim 11, wherein the new low pressure limit value is compared with the new tire pressure value.

13. The method of claim 10 further comprising monitoring the pressure of the tire upon a determination that the new tire pressure value is rejected.

14. The method of claim 10, wherein the low pressure condition occurs when the tire pressure is less than the low pressure limit value.

15. The method of claim 10, wherein the accepting step occurs upon a determination that the tire pressure should be modified.

16. A device for monitoring and adjusting tire pressure of a vehicle comprising:

a monitoring module configured to;

sense a tire pressure; and

compare the tire pressure with a low pressure limit value to identify a low pressure condition;

a computing module operatively coupled to the monitoring module, wherein the computing module includes;

an interface module configured to;

alert once the low pressure condition is identified;

accept a new load value upon a determination that the ire pressure should be modified;

display a new tire pressure value corresponding to the new load value selected; and

allow acceptance or rejection of the new tire pressure value; and

a processor configured to;

generate the new tire pressure value based on the new load value; and

modify the tire pressure to the new tire pressure value upon acceptance of the new tire pressure value.
