Wrong operation detection device, method, and program in tire pressure monitoring system

摘要

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 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.
