Abstract
This tire state estimation method includes the following. (1) Disposing, on the inner side of a tire, at least one power generator that generates voltage in response to deformation of the tire. (2) Acquiring measurement data in a time series obtained by measuring, while the tire is rotating, the voltage and/or a physical quantity corresponding to the voltage. (3) Identifying a peak that repeatedly appears in the measurement data. (4) Identifying a value of the peak and/or an interval of the peak. (5) Estimating the state of the tire on the basis of the identified value and/or the identified interval. The power generator is provided with a first member and a second member. The first member and the second member are configured such that one is positively charged and the other is negatively charged in accordance with pressure applied to the first member and the second member.
