Collision avoidance in vehicular networks
First Claim
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; and
a class-speed value.

Abstract
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.
