Patent ID: 7706930

Claim:
Method for inflating a tyre ( 5 ) on a vehicle wheel ( 3 ) by means of an inflation machine ( 2 ) controlled by a programmable data management unit ( 17 ), the said method comprising the steps of: a) using a wheel ( 3 ) where at least one of the components ( 4 , 5 and 6 ) of the wheel ( 3 ) is provided with an information medium ( 7 , 8 , 9 ) carrying a temperature sensor ( 20 ) able to supply a value of a temperature of the tyre ( 5 ) on the wheel, the said information medium ( 7 , 8 , 9 ) being able to be consulted automatically and able to supply, when it is consulted, at least one data item (T p ) that can be used for inflating the tyre, b) automatically consulting the said information medium ( 7 , 8 or 9 ) and automatically transmitting to the said programmable data management unit ( 17 ) at least the value of the temperature (T p ) of the tyre supplied by the temperature sensor ( 20 ), c) supplying to the programmable data management unit ( 17 ) at least one data item for defining a set value (P c ) for the inflation pressure of the tyre ( 5 ), d) measuring an ambient temperature on the site of the inflation machine ( 2 ), e) calculating an average value of the said ambient temperature over a predefined elapsed time period, f) calculating, on the basis of the said set value (P c ) for the inflation pressure, a corrected set value (P cc ) taking account of the value of the temperature (T p ) of the tyre ( 5 ) supplied by the temperature sensor ( 20 ), the corrected set value P cc being calculated according to the formula P cc = P c · T p T ref in which P c is the said set value for the inflation pressure, T p is the temperature of tyre ( 5 ) supplied by the temperature sensor ( 20 ) and T ref is a variable reference temperature chosen as being a lowest temperature amongst a ambient temperature measured on the site of the inflation machine ( 2 ) and the said calculated average value of the ambient temperature, the pressures P c and P cc being in absolute value and the temperatures T p and T ref being in degrees K, g) measuring a value of a pressure of the air inside the tyre ( 5 ), h) adjusting, by inflation or deflation, the value of the pressure of the air inside the tyre to the calculated corrected set value (P cc ).
