Abstract
Provided is a technology of estimating a bending stiffness variation of a tire and estimating a tread wear amount of a tire using the same. A tire wear measuring apparatus wear includes a signal receiver configured to measure acceleration inside the tire with respect to an axial direction, which is a radial direction of the tire, 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 by calculating a bending stiffness variation rate of the tire using axial acceleration inside the tire, a transmitter configured to receive and transmit analysis information, which is information on the tread wear rate of the tire, from the signal analyzer, 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. Meanwhile, a physical change thereof is derived using a Flexible Ring tire model which is a mathematical model.
