Abstract:
Provided is a technique for measuring a wear rate of a tire tread using tendency of a peak value of acceleration of the tire. According to an embodiment of the present disclosure, a tire wear measuring apparatus includes: a signal receiver configured to measure acceleration inside the tire installed to a the vehicle for each point inside the tire; a signal analyzer configured to receive signal information from the signal receiver and estimate a tread wear rate of the tire using a peak value of acceleration in longitudinal direction perpendicular to an axial direction of the tire from among acceleration signals inside the tire; 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 the vehicle to which the tire is installed. A physical change thereof is verified using a Flexible Ring tire model which is a mathematical model.
