Patent number: 11919337Abstract: 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.Type: GrantFiled: May 27, 2019Date of Patent: March 5, 2024Assignee: Bridgestone Europe N.V/S.A.Inventors: Lorenzo Alleva, Marco Pascucci

Patent number: 11458777Abstract: 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.Type: GrantFiled: July 30, 2019Date of Patent: October 4, 2022Assignee: Bridgestone Europe N.V./S.A.Inventors: Vincenzo Ciaravola, Marco Andrea Maggi, Alfredo Corollaro, Lorenzo Alleva, Alessandro Boldrini, Valerio Bortolotto, Rufini Flavia

Patent number: 11378625Abstract: 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.Type: GrantFiled: June 20, 2019Date of Patent: July 5, 2022Assignee: Bridgestone Europe, N.V./S.A.
