Cooperative geolocation based on inter-vehicular communication

摘要

Described herein is an automotive cooperative geolocation system based on inter-vehicular communication, comprising a first geolocation system (4) arranged, in use, on a first vehicle (2) equipped with an inter-vehicular communication system (3) and not equipped with an on-board geolocation system; and a second geolocation system (14) arranged, in use, on a second vehicle (11) equipped with both an both communication system (13) and an on-board geolocation system (12). The both communication systems (3, 13) are configured to automatically detect other inter-vehicular communication systems in their own communication ranges and to short-range communicate with the detected inter-vehicular communication systems, and the first and second geolocation systems (4, 14) are configured to cooperate with one another for geolocating an event detected by the first geolocation system (4). The first geolocation system (4) comprises an event detection unit (5, 6) configured to enable events that have occurred along the path of the first vehicle to be detected and identified; a measurement unit (7) configured to supply information indicating a distance covered by the first vehicle (2) from a detected event; and an electronic processing and control unit (8) configured to generate and transmit, through the inter-vehicular communication system (3) of the first vehicle (2), information indicating a detected event and a distance covered by the first vehicle (2) from the detected event. The second geolocation system (14) comprises, instead, an electronic processing and control unit (15) configured to extract the information received by the inter-vehicular communication system (13) of the second vehicle (11) and transmitted by the inter-vehicular communication system (3) of the first vehicle (2), and to geolocated the detected event based on the distance covered by the first vehicle (2) from the detected event and the current position of the second vehicle (11) supplied by the on-board location system (12) of the latter.
