Method for interacting road condition information under hybrid areas of motorcades

Abstract

In order to realize more rapid and more efficient transfer of information between trucks of motorcades, the invention discloses a method for interacting road condition information between the trucks of the motorcades. The method for interacting road condition information mainly comprises two manners, wherein the first manner is information transfer (wide area) between a traffic command center andvehicle nodes, the traffic command center releases traffic service information such as weather, road conditions and the like to the vehicle nodes in an effective communication range of the traffic command center, the nodes forward the information after receiving the information, and moreover, traffic information perceived by the vehicle nodes are also released to the command center; and the secondmanner is information transfer (local area) between the vehicle nodes. Before a freight motorcade sends cargoes, trucks are pairwise coupled (numbered as 1 and 2), the truck 2 is only controlled according to the local area information, and the truck 1 not only interacts with the local area information of the truck 2, but also interacts with an ITS wide area, so that the operation throughput is greatly reduced. The local areas of the two trucks are interacted without transferring all the road information, so that the transferred information amount is small and then the information is transferred more rapidly and efficiently. In the wide area, half of the ITS information interaction amount is reduced.

Description

technical field [0001] The invention belongs to the field of Internet of Vehicles and provides a method for exchanging road condition information between trucks in a fleet. [0002] technical background [0003] With the increase of people's demand for cars, there are more and more safety and efficiency problems in the driving of cars in modern society. Especially with the improvement of the level of industrialization, truck transportation pays special attention to efficiency, safety and cost. Many of its key problems lie in the lack of effective means of information communication between vehicle owners. [0004] The information transmission of the fleet usually includes two ways: the first way is the information transmission (wide area) between the traffic command center and the vehicle node, and the traffic command center issues traffic conditions such as weather and road conditions to the vehicle nodes within its effective communication range. Service information, the nod...

Problems solved by technology

[0005] The invention patent "an intelligent traffic road condition information collection device" (CN201811163758) adopts the method of multi-lane vehicles to collect road condition information, which avoids the congestion of the lanes with many vehicles and improves the traffic efficiency of vehicles. If limited vehicles are collected in the domain, the vehicles behind cannot obtain road condition information in a timely and effective manner, and it is difficult to avoid it in advance in the path planning stage. Therefore, it is necessary to realize the interconnection between the local area and the wide area and improve the efficiency of information use

[0006] The invention patent "a scheduling control method" (CN201810901208) adopts the method of obtaining a single vehicle ID to realize timely acquisition of road condition information and timely change of driving route and driving speed. Domain information, cannot guarantee that it will meet the transportation requirements
