| description | A device for estimating a condition of a road surface on which a tire is travelling, the device including: an acceleration sensor 11 that detects acceleration in a tire radial direction, an acceleration waveform extracting unit 12 that extracts an acceleration waveform from the acceleration, a differential waveform calculating unit 13 that calculates a differential waveform of the acceleration waveform, a rotation time calculating unit 14 that calculates a rotation time of the tire from the differential waveform, a normalized acceleration waveform generating unit 15 that generates a normalized acceleration waveform by using the rotation time, and a road surface condition estimating unit 16 that determines whether or not a water infiltration condition between the tire and the road surface is in a condition to be shifted to a hydroplaning condition. |
