Wrong operation detection device, method, and program in tire pressure monitoring system
First Claim
1. A wrong operation detection device for monitoring whether or not a calibration start for determining an initial deflation index is issued in a tire pressure unadjusted state after a deflation warning in a tire pressure monitoring system for detection of deflation of a tire by comparison with the initial deflation index based on rotation speed information and/or a resonance frequency after adjusting pressure of the tire equipped on a vehicle, the wrong operation detection device comprising:
- comparison means for comparing a first deflation index serving as a deflation index at any time point in a period from issue of the deflation warning to vehicle stop after the issue of the warning, with a second deflation index serving as a deflation index obtained after the calibration start,detection means for detection of wrong operation of a reset button based on a comparison result by the comparison means, andwarning means for issuing a warning when the detection means detects the wrong operation.

Abstract
A wrong operation detection device is disclosed for monitoring whether or not a calibration start for determining an initial deflation index is issued in a tire pressure unadjusted state after a deflation warning in a tire pressure monitoring system for detection of deflation of a tire. The device includes comparison means for comparing a first deflation index serving as a deflation index at any time point in a period from issue of the deflation warning to vehicle stop after the issue of the warning, with a second deflation index serving as a deflation index obtained after the calibration start; detection means for detection of wrong operation of a reset button based on a comparison result by the comparison means; and warning means for issuing a warning when the detection means detects the wrong operation.

4. A wrong operation detection method for monitoring whether or not a calibration start for determining an initial deflation index is issued in a tire pressure unadjusted state after a deflation warning in a tire pressure monitoring system for detection of deflation of a tire by comparison with the initial deflation index based on rotation speed information and/or a resonance frequency after adjusting pressure of the tire equipped on a vehicle, the wrong operation detection method including:
-
a comparison step for comparing a first deflation index serving as a deflation index at any time point in a period from issue of the deflation warning to vehicle stop after the issue of the warning with a second deflation index serving as a deflation index obtained after the calibration start, a detection step for detecting wrong operation based on a comparison result in the comparison step, and a warning step for issuing a warning when the wrong operation is detected in the detection step. - View Dependent Claims (5, 6)

7. A wrong operation detection program in a tire pressure monitoring system which, in order to monitor whether or not a calibration start for determining an initial deflation index is issued in a tire pressure unadjusted state after a deflation warning in a tire pressure monitoring system for detection of deflation of a tire by comparison with the initial deflation index based on rotation speed info nation and/or a resonance frequency after adjusting pressure of the tire equipped on a vehicle, makes a computer function as
comparison means for comparing a first deflation index serving as a deflation index at any time point in a period from issue of the deflation warning to vehicle stop after the issue of the warning, with a second deflation index serving as a deflation index obtained after the calibration start, and detection means for detection of wrong operation based on a comparison result.
