Abstract

A tire deflation determination system includes: a first acquisition processing unit 51A configured to acquire a rotation speed of each tire mounted on a vehicle 1A; a second acquisition processing unit 54A configured to acquire a resonance frequency of the tire, based on the acquired rotation speed; a replacement determination processing unit 58A configured to determine whether or not a difference between the acquired resonance frequency and a reference frequency exceeds a first determination value; and a change processing unit 59 configured to, if it is determined that the difference between the resonance frequency and the reference frequency exceeds the first determination value, change a threshold value used in a deflation determination process of determining whether or not the tire has become deflated.
