  "textContent": "In order to provide a method and a device for determining a tire type of a running tire from a vehicle side, when determining the tire type, which is the type of the tire, from an output of an acceleration sensor attached to an inner surface side of a tire tread of the tire mounted on a vehicle, a feature vector is extracted from an acceleration waveform detected from the output of the acceleration sensor, and the tire type of the tire is determined, by a machine learning algorithm, from the extracted feature vector. The tire type is determined on the basis of the extracted feature vector and a determination model in which a feature vector obtained in advance for each tire type has been configured as learning data.",
