Patent number: 7209855Abstract: The invention relates to a method for filtering information emitted, on the basis of pressure measurements taken by a pressure sensor mounted on a wheel of a vehicle equipped with a tire, to a central unit mounted on the vehicle. According to this method, a value representative of the pressure of the air in the tire is measured periodically, with a period ?, and from this any possible variations ?P in pressure between the values of the pressures successively measured are deduced; in parallel, with the same period ?, a value representative of the temperature of the air in the tire is measured. In addition, when there is a variation ?P in pressure between two measured pressure values, that is greater in terms of absolute value than a predetermined threshold Sp, the variation ?T between the two temperature values measured at the same instants as the measured pressures is calculated.Type: GrantFiled: September 1, 2005Date of Patent: April 24, 2007Assignee: Siemens VDO AutomotiveInventors: Laurent Fabre, Georges Fonzes
