Tire deflation detection system with feedback component
First Claim
1. A system for detecting a deflated tire on a vehicle, the system comprising:
- an evaluating process that determines when a tire is likely to be deflated and issues a warning when the evaluating process determines a tire is likely to be deflated; and
a feedback component that provides feedback to the evaluating process indicating whether the issued warning was erroneous.

Abstract
A system for detecting a deflated tire on a vehicle. The system includes an evaluating process that determines when a tire is likely to be deflated and issues a warning when the evaluating process determines a tire is likely to be deflated. The system further includes a feedback component that provides feedback to the evaluating process indicating whether the issued warning was erroneous. In one aspect of the invention, the feedback component makes corrections to the evaluating process. In another aspect of the invention, the feedback component is a direct feedback component. In yet another aspect of the invention, the feedback component is an inferred feedback component.

9. A method of reducing the number of erroneous warnings issued from a tire deflation detection system-on a-vehicle, the tire deflation detection system having an evaluation process capable of evaluating wheel speed data to determine whether a tire is likely to be deflated, and issuing a warning to a driver of the vehicle when the system determines a tire is likely to be deflated, the method comprising:
-
resetting the system after a warning has been issued;
continuing the evaluation process after the system is reset; and
comparing a result of the evaluation process generated prior to the issuance of the warning to a result of the evaluation process generated after the system is reset to determine whether the warning was improper. - View Dependent Claims (10, 11, 12)

13. A method of detecting a deflated tire on a vehicle with a tire deflation detection system, the method comprising:
-
measuring a wheel speed of a wheel on the vehicle a plurality of times;
evaluating the wheel speeds to determine whether a tire is likely to be deflated;
issuing a warning when the system determines a tire is likely to be deflated; and
determining whether the warning was improper. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
resetting the evaluating process after the warning has been issued;
continuing the evaluating process after reset; and
comparing a result of the evaluating process generated prior to the issuance of the warning to a result of the evaluating process generated after reset.

23. The deflation detection method of claim 13, wherein determining whether the warning was improper includes obtaining direct feedback from the driver regarding whether the warning was erroneously issued.
-
24. The deflation detection method of claim 13, further including making a correction to the evaluating process when the system determines the warning was improper.
-
25. The deflation detection method of claim 24, wherein the evaluating process includes a deflation detection process that generates signal values based on the wheel speeds, and wherein making a correction includes adjusting the signal values.
-
26. The deflation detection method of claim 24, wherein the evaluating process includes a deflation detection process that includes a predetermined threshold value, and wherein making a correction includes adjusting the predetermined threshold value.
