    Abstract: The distribution of a specific pressure in the ground-contacting area of a tire (4) under examination is detected by means of a plurality of sensing cells (7) distributed on a plate-like support (8) applied to a rest surface (2) acted upon by the tire through its rolling surface (5). Each sensing cell (7) sends an electric signal correlated with the specific pressure applied thereto to a processing unit (10) through which the processed signals are sent to a display device (12) graphically representing the distribution of the specific pressure in the ground-contacting area. By causing the tire (4) to roll on the rest surface (2) and therefore the sensing cells (7), the dynamic variation of the specific pressures in the ground-contacting area can be detected. A protection sheet (11) interposed between the rolling surface of the tire (4) and the sensing cells (7) protects the latter against risks of damages due to tangential shearing stresses produced at the ground-contacting area.

    Abstract: A method for determining a load exerted on a tire, fitted on a vehicle, during running of the vehicle on a rolling surface, is disclosed. The method includes acquiring a first signal comprising a first signal portion representative of a radial deformation; measuring an amplitude of the radial deformation in the first signal portion; estimating a rotation speed of the tire corresponding to the radial deformation; estimating an inflation pressure of the tire corresponding to the radial deformation; and deriving the load exerted on the tire from the amplitude, the rotation speed, and the inflation pressure. The first signal portion is representative of the radial deformation to which a first tread area portion of the tire is subjected during passage of the first tread area portion through a contact region between the tire and the rolling surface. A system for determining the load exerted on the tire is also disclosed.

    Abstract: An oscillating structure is coupled to a crown portion of a tire. The oscillating structure includes a housing and a piezoelectric element coupled to the housing. The piezoelectric element is able to oscillate in an oscillation direction, which could match either a longitudinal or a radial direction of the tire. An electrical signal generated by the piezoelectric element is processed so as to determine at least one operating parameter of the tire. The processing includes determining whether a rotation speed of the tire is greater than a threshold speed; and, in the negative, extracting information for determining the at least one operating parameter of the tire from a low-pass filtered signal. Such low-pass filtered signal is obtained by removing at least frequency components of the electrical signal having a frequency higher than or equal to a resonance peak frequency of the oscillating structure.
