Abstract: The invention concerns a tread wear monitoring method comprising a tread wear model calibration step (1) and a tread wear monitoring step (2), wherein the tread wear model calibration step (1) includes determining (13) a calibrated tread wear model based on tread-wear-related quantities and first frictional-energy-related quantities. The tread wear monitoring step (2) includes: acquiring (21), from a vehicle bus (40) of a motor vehicle (4) equipped with two or more wheels fitted, each, with a tire, driving-related quantities related to driving of the motor vehicle (4); computing (22) second frictional-energy-related quantities related to frictional energy experienced, during driving, by a given tire of the motor vehicle (4) by providing a predefined vehicle dynamics model that mathematically relates the acquired driving-related quantities to the second frictional-energy-related quantities, and computing the second frictional-energy-related quantities by inputting the acquired driving-related quantities into the predefined vehicle dynamics model; and performing a tread wear estimation (23) and a remaining tread material prediction (24) based on the second frictional-energy-related quantities computed and the calibrated tread wear model. The tread wear model calibration step (1) further includes: performing (11) tread wear tests on one or more tires; and measuring (12) tread-wear-related quantities indicative of tread depth reductions resulting from the performed tread wear tests, and first frictional-energy-related quantities related to frictional energy which the tested tire(s) is/are subject to during the performed tread wear tests. Determining (13) a calibrated tread wear model includes: providing a predefined reference tread wear model that mathematically relates frictional energy experienced by a tire along a driving route to tread wear caused by said frictional energy through given parameters; computing calibration values of the given parameters by inputting the measured tread-wear-related and first frictional-energy-related quantities into the predefined reference tread wear model; and determining the calibrated tread wear model by applying the computed calibration values in the predefined reference tread wear model.

Abstract: The invention concerns a method (1) for detecting and locating obstacles/elements on road pavement, including: acquiring (11) wheel speed values related to a wheel of a motor vehicle driven on a road, and georeferencing data associated with the wheel speed values and indicative of corresponding positions of the motor vehicle; detecting (12) an obstacle/element present on the road based on the acquired wheel speed values by identifying an entry time instant at which the wheel meets the obstacle/element, and an exit time instant at which the wheel has gone beyond said obstacle/element, and by computing a normalized peak-to-peak value related to the obstacle/element based on a maximum value and a minimum value of the acquired wheel speed values related to impact-related time instants comprised between the entry and exit time instants, and an average value of the acquired wheel speed values related to first impact-freetime instants immediately before the entry time instant; determining (13) a severity degree associated with the obstacle/element based on the normalized peak-to-peak value; determining (14) a position of the obstacle/element based on the acquired georeferencing data associated with one or more of the acquired wheel speed values related to the impact-related time instants and/or to the first impact-free time instants and/or to second impact-free time instants 39 immediately after the exit time instant; and storing (15) the position of the obstacle/element along with the severity degree associated therewith.
