  • Patent number: 11919337
    Abstract: A tire damage detection method includes a preliminary stage comprising: performing tests involving test tire impacts against/on different obstacles at different motor vehicle speeds; measuring/acquiring test-related wheel speeds during the performed tests; computing test-related normalized wheel speeds based on the test-related wheel speeds; and determining a predefined tire damage model based on the test-related normalized wheel speeds corresponding to the test tire impacts and of associated test-related average wheel speeds. A tire damage detection stage comprises: acquiring signals indicative of a motor vehicle wheel speed; computing, based on quantities indicative of the wheel speed, a normalized wheel speed indicative of a ratio of the wheel speed to an average wheel speed indicative of motor vehicle speed; and detecting potential damage to a tire of the wheel based on the predefined tire damage model and on the normalized wheel speed.

  • Patent number: 11541703
    Abstract: A pneumatic tire (1) having: a toroidal carcass (2), which is comprised of a body ply (3) partially collapsed onto itself and therefore having two lateral flaps; two annular beads (4), each of which is surrounded by the body ply (3) and has a bead core (5) and a bead filler (6); an annular tread (7); a pair of sidewalls (11) arranged externally to the body ply (3) between the tread (7) and the beads (4); a pair of abrasion gum strips (12) arranged externally to the body ply (3) under the sidewalls (13) and at the beads (4); and a transponder (13) which is arranged in contact with the body ply (3) at a flap of the body ply (3) and is located below an edge (19) of the body ply (3) between the edge (19) of the body ply (3) and the bead (4).

  • Patent number: 11458777
    Abstract: The invention concerns a tread wear monitoring method comprising a preliminary step (6) and a tread wear monitoring step (7). The preliminary step (6) includes: performing tread wear tests on one or more tires; measuring tread-wear-related quantities and first frictional-energy-related quantities, wherein the tread wear-related quantities are indicative of tread wear resulting from the performed tread wear tests, and the first frictional-energy-related quantities are related to frictional energy which the tested tire(s) is/are subject to during the performed tread wear tests; and determining a calibrated tread wear model based on the measured tread-wear-related and first frictional-energy-related quantities.

  • Patent number: 11378625
    Abstract: The invention concerns a motor vehicle battery wear monitoring system (1,1A,1B) that includes an acquisition device (11) and a processing device/system (12,12A,12B). The acquisition device (11) is: installed onboard a motor vehicle (2) that is equipped with an internal combustion engine, a battery for providing a battery voltage (VB), an alternator, and a starter motor for starting up the internal combustion engine; and configured to receive the battery voltage (VB) and to output quantities indicative of said battery voltage (VB). The processing device/system (12,12A,12B) is: configured to receive the quantities indicative of the battery voltage (VB) from the acquisition device (11); and programmed to perform a battery voltage monitoring based on the quantities indicative of the battery voltage (VB) to detect an approaching battery failure.
