Collision avoidance in vehicular networks

摘要

A method and nodes for collision avoidance in a vehicular network comprising a plurality of vehicles and lower-speed users. Data from a plurality of position notification messages sent from the lower-speed-node is received (directly from the lower-speed-node or through a road-side-node) and processed, in a vehicle-on-board-node of a moving vehicle, with positioning data of the moving vehicle into collision avoidance instructions. The collision avoidance instructions may be provided inside the vehicle by displaying the instructions on a screen and/or broadcasting the instructions through a speaker in the vehicle. The collision avoidance instructions may also be automatically applied by modifying dynamic parameters of the vehicle (e.g., affecting the vehicle speed and/or changing direction of the vehicle). The position notification message may comprise a sequential number value; a temporary ID value; a geographic latitude value; a geographic longitude value; and a class-speed value.

1. A method for collision avoidance in a vehicular network comprising a plurality of vehicles and lower-speed users of the vehicular network, the method comprising:
periodically receiving a position notification message, from a lower-speed-node, for use by a vehicle-on-board-node in a moving vehicle; in the vehicle-on-board-node, receiving data from a plurality of position notification messages sent from the lower-speed-node; and in the vehicle-on-board-node, processing the data related to the plurality of position notification messages with positioning data of the moving vehicle into collision avoidance instructions; wherein the position notification message comprises:
a sequential number value;a temporary ID value;a geographic latitude value of the lower-speed-node;a geographic longitude value of the lower-speed-node; anda class-speed value.
