Title:
TIRE-MOUNTED SENSOR AND ROAD SURFACE CONDITION ESTIMATING DEVICE INCLUDING SAME
Document Type and Number:
WIPO Patent Application WO/2018/012249
Kind Code:
A1
Abstract:
According to the present invention, a grounding section is extracted on the basis of a signal detected by a first acceleration sensor (11a) only during a time period in which a grounding angle based on the rotation angle of a tire (3) is satisfied. Accordingly, even when noise of vibration due to the irregularity of a road surface is superimposed on a signal detected by the first acceleration sensor (11a), an erroneous determination of a grounding section can be inhibited. Consequently, an erroneous determination of a grounding section can be inhibited even when the travel road surface has great irregularity.
