Tire wear measuring device and tire wear measuring method using the same

Abstract

The invention provides a technology for measuring the wear rate of a tire tread by utilizing the trend of an extreme value of the acceleration of a tire. A tire wear measuring device using an acceleration limit value of a tire according to an embodiment of the present invention includes: a signal receiving unit that measures an acceleration inside a tire provided in a vehicle for each position inside the tire; a signal analysis unit which receives the signal information from the signal reception unit and estimates a tread wear rate of the tire by using an extreme value of a longitudinal acceleration perpendicular to an axial direction which is a radial direction of the tire in an acceleration signal inside the tire; a transmission unit that receives analysis information from the signal analysis unit, the analysis information being information relating to a tread wear rate of the tire, and transmits the analysis information; and a control module that generates a control signal related to the vehicle on which the tire is provided by receiving the analysis information from the transmission unit. On the other hand, the physical change was confirmed by using a mathematical Model (Flexible Ring fire Model).
