Abstract:
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.
