METHOD FOR ALLOWING A CONTROL OF A VEHICLE PROVIDED WITH AT LEAST TWO WHEELS IN CASE OF PUNCTURE OF A TYRE

摘要

It is disclosed a method of allowing a control of a vehicle provided with at least two wheels in case of puncture of a tyre, each wheel (1) comprising a rim (2) and a tyre (3) associated therewith, said method comprising the steps of: inflating each tyre (3) to an operating pressure (PE) at a reference temperature (TR); admitting a fluid compressed to a first pressure (PP) higher than the operating pressure (PE) of said tyre at the reference temperature (TR) , into at least one tank (4) associated with at least one of said rims (2); bringing said tyre (3) into communication with said tank (4) when the inner pressure (Pi) of said tyre is lower than said operating pressure (PE) by a predetermined first threshold value (Vs*); measuring the inner pressure (Pi) of said tyre (3) with a predetermined frequency (F); calculating a variation (Vp) of said inner pressure (Pi) in the time unit; generating an alarm signal when said variation of the inner pressure (Pi) corresponds to a reduction and is higher than a predetermined value (Vp*); transmitting said alarm signal to the driver.
