TRAVELABLE DISTANCE ESTIMATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To precisely estimate travelable distance capable of traveling in a state of puncture of the run-flat tire in a vehicle with wheels having run-flat tires. SOLUTION: The vehicle with wheels 10 having run-flat tires 20 is provided with a device which estimates the travelable distance L capable traveling in the state of puncture of the run-flat tire. The device comprises (a) a tire load state quantity sensor 42 which is mounted to the run-flat tire and detects the tire load state quantity (for example, temperature and strain) of the state quantity expressing the load and (b) an estimation apparatus estimating the travelable distance L based on the detected tire load state quantity.
