Patent ID: 8104335

Claim:
A method for measuring an inflation pressure of a vehicle tire that includes an interior rubber mass, delimited by an internal surface in contact with air inside the vehicle tire and an external surface in contact with a carcass ply of the vehicle tire, the method comprising: measuring compressive stress values in the interior rubber mass between the internal and external surfaces of the interior rubber mass, wherein the measuring is performed using a sensor, which is located on or in the interior rubber mass, while the vehicle tire is rolling on a ground surface, and wherein the compressive stress values include (1) measured compressive stress values within a zone corresponding to an angular interval in which the sensor is influenced by contact of the vehicle tire with the ground surface, and (2) measured compressive stress values outside of the zone corresponding to the angular interval in which the sensor is influenced by contact of the vehicle tire with the ground surface; and obtaining the inflation pressure from the measured compressive stress values outside of the zone corresponding to the angular interval in which the sensor is influenced by contact of the vehicle tire with the ground surface.
