Vehicle formation method and system based on V2I (vehicle-to-infrastructure) cooperative technology

Abstract

An embodiment of the invention discloses a vehicle formation method and system based on a V2I (vehicle-to-infrastructure) cooperative technology and relates to the technical field of V2I cooperation.The method comprises the steps as follows: a vehicle A periodically broadcasts pre-formation information, wherein the vehicle A is any vehicle with a V2V (vehicle-to-vehicle) cooperation function; a vehicle B communicates with the vehicle A through a V2V device after receiving the pre-formation information of the vehicle A to construct a queue, and a pilot vehicle and a first formed vehicle are determined according to a formation rule; the first formed vehicle sends formation completion information to the pilot vehicle; the pilot vehicle periodically broadcasts formation information; any vehicle C joins the queue after receiving the formation information to become a second formed vehicle to the Nth formed vehicle; vehicles are forbidden to join the queue until the length of the queue reaches pre-formation length of the pilot vehicle or the formed member number reaches a preset member number of the pilot vehicle. The vehicle formation method and system can solve the problem of low efficiency of vehicle formation running methods in the prior art.

Description

technical field

[0001] Embodiments of the present invention relate to the technical field of vehicle-road coordination, and in particular to a vehicle formation method and system based on vehicle-road coordination technology. Background technique

[0002] The Internet of Vehicles is through the Internet technology, all vehicles can transmit various information of themselves to the central processing unit. Through computer technology, the information of these large numbers of vehicles can be analyzed and processed to calculate the best routes for different vehicles, issue reports on road conditions and adjust signal light cycles. The vehicle-to-road collaboration technology V2X of the Internet of Vehicles includes the interconnection of vehicles and vehicles (V2V), vehicles and roads (V2I), vehicles and people (V2P), and vehicles and centers (V2C). Communication and roaming between structured networks ensure real-time, serviceability and network ubiquity in terms of function...
