Abstract

The invention discloses a road area division method for vehicle local area networking based on multi-source sensing technology. First, a vehicle terminal system is mounted on the vehicle, and a virtual wall system is used to collect vehicle information; It is divided into several communication areas, including three division strategies based on road vehicle capacity, signal attenuation and intersection classification; finally, regional coordination is carried out according to the divided areas. The method of the invention has low cost of laying relevant sensors, and improves the feasibility of practical engineering. Improve the stability of vehicle networking and adapt to a variety of complex road conditions.

Description

technical field [0001] The invention belongs to the technical field of vehicle networking, and in particular relates to a road area division method for vehicle local area networking. Background technique [0002] The division of vehicle road areas depends on precise positioning, that is, based on Beidou, GPS differential positioning, and methods based on video acquisition combined with digital image processing and other technologies, but the low civilian penetration rate and high technology costs are not conducive to engineering application implementation and promotion. Vehicle local area networking has high requirements for vehicle area division during driving. In the process of vehicle-road coordination, effectively and accurately completing vehicle area division is of great significance for realizing vehicle local area network communication. [0003] At present, there is no road area division method based on multi-source sensing technology to confirm vehicle location info...
