Method and system of detection of a run-flat condition of a tire; inserts, wheels and tires designed for such method and system

摘要

A method of detection of a run-flat condition of a vehicle tire, said tire being mounted on a wheel, wherein:a quantity f(α, t) is sensed, which varies which the angular displacement of the wheel in time;measuring signals are elaborated, which vary with the angular speed of the wheel dα(t)/dt;a quantity characteristic of the dispersion of measuring signals is calculated;an alarm is set off when the characteristic quantity satisfies a given ratio.
