A tire wear measuring apparatus using irregularity of an acceleration signal of a tire, the apparatus comprising: a signal receiver configured to measure acceleration inside a tire with respect to a radial direction of the tire, for each of a plurality of points 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 to extract residual vibration from 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 and reflecting the residual vibration; 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, characterized in that the signal analyzer is configured to quantify the irregularity of the acceleration signal by quantifying the irregularity of the processed signal using the following equation according to Euclidean distance analysis: U = ∑ i = 1 n x i, j − x i, j − 1 where U is a number of Euclidean distances; n is a natural number which is equal to or greater than 1 and which indicates a total number of points at which the acceleration is measured inside the tire while the tire is rotating; i is an order number for each point at which the acceleration is measured inside the tire; and j is a number of rotations of the tire. a signal receiver configured to measure acceleration inside a tire with respect to a radial direction of the tire, for each of a plurality of points 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 to extract residual vibration from 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 and reflecting the residual vibration; 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, characterized in that the signal analyzer is configured to quantify the irregularity of the acceleration signal by quantifying the irregularity of the processed signal using the following equation according to Euclidean distance analysis: U = ∑ i = 1 n x i, j − x i, j − 1 where U is a number of Euclidean distances; n is a natural number which is equal to or greater than 1 and which indicates a total number of points at which the acceleration is measured inside the tire while the tire is rotating; i is an order number for each point at which the acceleration is measured inside the tire; and j is a number of rotations of the tire.
