  • Patent number: 10328755
    Abstract: A method and system for estimating the load acting on a tire, wherein data are obtained, representative of the deformation undergone by the tire on a rolling surface. The data obtained are processed in order to obtain a first quantity representative of the deformation extent within a first deformation region substantially corresponding to the footprint between the tire and the rolling surface and a second quantity, different from the first quantity, representative of the deformation extent in a second deformation region, the second region including the first deformation region and having a circumferential extension greater than the circumferential extension of the first deformation region, the second quantity being obtained starting from at least a part of the obtained data, which corresponds to a portion of the second deformation region which is external to the footprint. The load is estimated based on the first quantity and the second quantity thus obtained.

  • Patent number: 8019502
    Abstract: A method for monitoring a tire during running includes acquiring and storing, at least temporarily, a first curve representing an acceleration profile of a first point of a tread area of the tire; acquiring and storing, at least temporarily, at least one second curve representing an acceleration profile of a second point of the tread area; and comparing the first curve and the at least one second curve, or parameters derived from the first curve and the at least one second curve, so as to determine a dynamic behavior of the tire. The first and second points are located substantially on a same meridian plane of the tire. A related tire, wheel for a vehicle, system for monitoring a tire during running, and method for controlling a vehicle are also disclosed.

  • Patent number: 7999663
    Abstract: Fastened to a tire is a detecting device consisting of a detecting unit including an antenna operatively connected to a sensor unit and a power supply unit including a piezoelectric element mounted in a housing. The piezoelectric element is disposed within the housing so as to have a first end substantially fixed to the housing and a second end associated with a loading mass, a gap being formed between at least one inner wall of the housing and an outer surface of the loading mass. The piezoelectric element is positioned substantially along a plane orthogonal to a radial direction of the tire. An anchoring body has a base portion with a fastening surface secured to the radially internal surface of the tire. The detecting unit is brought into engagement with the anchoring body by insertion of the inner perimetral edge of the antenna into a perimetral groove formed between the base portion and a retaining portion.
