Abstract:
A system for assessing a level of danger of an occurrence of failure of a mounted tire to a vehicle, and notifying a person of the level of the danger according to a result of the assessment, the system comprising:a tire inflation pressure measuring device for monitoring a tire inflation pressure of the mounted tire; a tire running speed measuring device for monitoring a tire running speed of the mounted tire; a danger level assessment device for, at least in a case where the tire running speed obtained by the monitoring is higher than a given reference speed, calculating a danger level assessment value indicating an index showing a probability of the occurrence of the failure of the mounted tire from the tire inflation pressure obtained by the monitoring by the tire inflation pressure measuring device and from the tire running speed obtained by the monitoring by the tire running speed measuring device, based on a danger level assessing function, and assessing the danger level of the occurrence of the tire failure of the mounted tire from the danger level assessment value; and a notification device for notifying a person of the danger level of the occurrence of the failure of the mounted tire, according to a result of the assessment of the danger level, wherein the danger level assessing function is a function of the tire running speed and of the tire inflation pressure, in which, at least when the tire running speed is in a speed range above the given reference speed, a value of the function monotonically increases as the tire running speed increases, and the value of the function increases as the tire inflation pressure decreases.
