Abstract
A method is provided for detecting and locating obstacles/elements on road pavement, including: acquiring driven wheel speed values, and georeferencing data indicative of corresponding motor vehicle positions; detecting obstacles/elements present on the road based on the wheel speed values by identifying entry time instants at which the wheel meets the obstacles/elements, and exit time instants at which the wheel has gone beyond said obstacles/elements, and by computing normalized peak-to-peak values related to the obstacles/elements based on maximum and minimum wheel speed values related to impact-related time instants comprised between the entry and exit time instants, and an average value of the wheel speed values related to first impact-free time instants immediately before the entry time instants; determining a severity degree for each respective obstacle/element based on the normalized peak-to-peak value; determining and storing a position of the obstacle/element based on the georeferencing data, along with the severity degree associated therewith.
