METHOD FOR EVALUATING THE AUTONOMY OF A FLAT ROLLING SYSTEM

摘要

The invention concerns a method for assessing the endurance of a motor vehicle running flat system comprising at least for each wheel a tyre casing, a deflation alarm and means supporting the running tread of the tyre casing when the casing is deflated, which, from the instant the deflation alarm has detected a predetermined deflating threshold, consists in: periodically measuring the distance covered and a parameter C(t) characteristic of the running conditions; determining on the basis of C(t) and the measured distance over DELTA t a quantity characteristic of potential elementary damage of the system during the time elapsed DELTA t; calculating an estimate of the global damage by combining the calculated elementary damage levels since the start of flat running; and transmitting to the vehicle driver a quantity related to that estimate of the flat running system global damage.
