  "textContent": "The invention concerns a method () for detecting and locating obstacles/elements on road pavement, including: acquiring () 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 () 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 () a severity degree associated with the obstacle/element based on the normalized peak-to-peak value; determining () 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 () the position of the obstacle/element along with the severity degree associated therewith.",
