TIRE WEAR MEASURING APPARATUS USING IRREGULARITY OF TIRE ACCELERATION SIGNAL AND TIRE WEAR MEASURING METHOD USING SAME

Provided is a technique of quantifying a change in irregularity appearing in an acceleration signal of a tire and measuring a tread wear amount of the tire using the quantified change. A tire wear measuring apparatus according to an embodiment of the present disclosure includes: a signal receiver configured to measure acceleration inside a tire with respect to an axial direction, which is a radial direction of the tire, for each point inside the tire; a broad pass filter configured to receive the measured acceleration signal from the signal receiver and perform filtering as a preprocessing on the acceleration signal; a signal analyzer configured to estimate a tread wear rate of the tire by quantifying irregularity of the acceleration signal using a processed signal that is a signal filtered through the broad pass filter; a transmitter configured to receive analysis information, which is information on the tread wear rate of the tire, from the signal analyzer and transmit the analysis information; and a control module configured to receive the analysis information from the transmitter and generate a control signal for a vehicle to which the tire is installed.
