Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] The specific implementation steps of the technical solution adopted by the present invention to solve the technical problems are as follows:

[0028] Such as figure 1 As shown, ①② in the figure indicates the jump position of the flow chart, for example, when the left figure is executed to ①, it will jump to the right figure ① to continue execution;

[0029] Step S1, a beacon device broadcasts a signal, the beacon device broadcasts a networking area identification signal on a public channel, and divides the road into different networking areas according to the signal coverage;

[0030] The vehicle is equipped with short-distance networking equipment, and through the short-distance networking equipment, the vehicle and adjacent vehicles form a wireless local area network;

[0031] Vehicle-mounted sensor equipment includes but is not limited to ra...

Abstract

The invention provides a networking method for vehicle area communication. The method comprises steps of when the existence of the networking target vehicle is detected, starting short-distance networking equipment on the vehicle; and preparing networking communication, updating the network member relationship table after the vehicle networking succeeds, broadcasting and informing all vehicles inthe local area network, periodically broadcasting the own position and motion information of the networking target vehicle through the network, and judging whether networking is carried out or not according to whether the networking target vehicle has an adjacent vehicle or not and whether the networking target vehicle receives the information in the network or not. According to the invention, thevehicle-mounted sensor information is fused, the networking target capture accuracy is improved, the information does not need to be periodically broadcasted to the public network, the bandwidth pressure on the common network during vehicle networking is relieved, the screening range of the target vehicles is reduced, and the networking rapidity is improved.

Description

technical field [0001] The invention relates to the field of vehicle networking, in particular to a networking method for vehicles. Background technique [0002] In the traditional networking between vehicles, the vehicle uploads its own information through broadcasting, such as: current location, running direction, and sends it to the public network, so that adjacent nodes can judge whether to establish a communication connection according to whether the driving direction and speed are consistent. relation. If the communication connection relationship is established, the communication connection relationship table of the vehicle is updated, and the communication connection relationship is broadcast to its adjacent vehicles, so that all vehicles in the group receive all the communication connection relationships. Calculate the end-to-end path topology diagram in the group, and notify all vehicle nodes in the group, and all vehicles in the group will send and receive informa...
