  • Patent number: 7832288
    Abstract: A method for determining the force at the hub of a wheel of a vehicle while traveling. The wheel includes a rim and at least one deformation sensor directly associated with the rim in at least one predetermined position and arranged according to at least one predetermined orientation. The method includes the steps of detecting at least one deformation component of the rim during travel through the at least one deformation sensor; applying to the at least one deformation component, during travel, a correlation parameter characteristic of the rim, between the force at the hub and the relative deformation of the rim to determine at least one force component at the hub correlated with the at least one deformation component of the rim.

  • Patent number: 7756670
    Abstract: A method for determining the roughness of a tyre rolling surface by the steps of providing a first signal representative of the motion of at least one point of the tyre during rolling of the surface and processing the first signal for providing an output indicative of the roughness of the rolling surface of the tyre.

  • Patent number: 7415874
    Abstract: A tire has a piezoelectric flexing element associated with an energy storage device (e.g., a capacitor). The piezoelectric flexure element is mounted in cantilever fashion in a housing so as to be positioned substantially along a plane orthogonal to a radial direction of the tire and, so that a first end of the piezoelement is restrained by the housing. A loading mass is coupled to the second end of the piezoelectric flexure element. A small gap is formed between the inner walls of the housing and the outer surface of the loading mass in order to allow limited flexure of the piezo-electric element. The housing including the piezoelectric is mounted in a tire portion in correspondence of a tread area of the tire, preferably on the inner surface of the tire. The piezoelectric element flexes under the action of the radial acceleration when the tire rotates.
