  • Method of measuring the three-dimensional profile of a ground, and device for implementing said method
    Patent number: 7984646
    Abstract: A method of measuring the profile, in three dimensions, of a pavement on which vehicles fitted with at least one tire may run. A first topographical measurement is carried out on site with a precision of at least one millimeter of an elementary surface of said pavement, then the points of contact between said surface and the tread of a given tire are defined and at least a second topographical measurement of said points of contact is carried out on site so as to obtain a three-dimensional representation, with a resolution of the order of one micron, of the microroughness of said points of contact.
    Type: Grant
    Filed: December 12, 2006
    Date of Patent: July 26, 2011
    Assignee: Michelin Recherche et Technique S.A.
    Inventors: Olivier Muhlhoff, Marc Chabry

  • Wheel and tire assembly and method of dynamically measuring topological parameters of the inside surface of the pertinent portion of the tire
    Patent number: 7502124
    Abstract: The wheel and tire assembly for running on ground includes measurement means carried by the wheel for measuring topological parameters of the inside surface of a pertinent portion of the tire. These measurement means comprise lighting and viewing means for lighting and viewing a calibrated surface pattern that is subjected to the deformation of the inside surface of the pertinent portion of the tire. The viewing means are preferably of the stereovision type or of the structured light type.
