Patent ID: 7594433

Claim:
A method of processing data from a vehicle tire monitoring system, the system regularly supplying for at least one tire values of the pressure and temperature of the fluid in the internal cavity of the said tire, in which, for a given tire: for a first given period of time, referred to as the reference period: a device divides up, by class of temperature [T] i , all the tire pressure and temperature values of the tire supplied during the reference period; and for each class of temperature [T] i , said device calculates the mean pressure ( p i,r ) of the corresponding pressure values: for at least a second given period of time, referred to as period j: said device divides up by class of temperature [T] i all the tire pressure and temperature values supplied during the period of time j; for each class of temperature, said device calculates the mean pressure ( p i,j ) of the corresponding pressure values; for each class of temperature, said device calculates the difference between the mean pressure and the reference mean pressure (Δp i,j = p i,j − p i,r ); and said device calculates the mean value of the differences between the mean pressures and the mean reference pressures Δp j .
