A method for estimating the state of a tire includes the following steps. (1) The inside of the tire is provided with at least one power generator that generates a voltage in response to the deformation of the tire. And (2) acquiring time-series measurement data obtained by measuring at least one of the voltage and a physical quantity corresponding to the voltage during rotation of the tire. And (3) determining peaks repeatedly appearing in the measurement data. And (4) specifying at least one of the value of the peak and the interval between the peaks. And (5) estimating the state of the tire on the basis of at least one of the specified value and the specified interval. The power generating body has a first member and a second member. The first member and the second member are configured so that one is positively charged and the other is negatively charged in response to pressure applied to the first member and the second member.
轮胎的状态的推测方法包含如下步骤。(1)在轮胎的内侧配置至少1个根据所述轮胎的变形而产生电压的发电体。(2)在所述轮胎旋转的期间,获取对所述电压以及与所述电压相当的物理量中的至少1个进行测量而得的时间序列的测量数据。(3)确定在所述测量数据中反复出现的峰。(4)确定所述峰的值和所述峰的间隔中的至少一方。(5)根据所述确定的值以及间隔中的至少一方来推测所述轮胎的状态。所述发电体具有第1部件和第2部件。第1部件和第2部件构成为根据施加于所述第1部件和所述第2部件的压力而使一方带正电,另一方带负电。
