Embodiment Construction

[0016] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.

[0017] The present invention is a road network hacker vehicle positioning method based on a dedicated short-range communication network, comprising the following steps:

[0018] Step 1: Collect the acceleration values ​​of vehicles in the road network when they encounter typical traffic events. Typical traffic events include: encountering traffic lights at intersections, overtaking, following cars, etc., collecting special short-range communication signals in the road network in the two workshops Propagated transmit power and receive power, and record the relative distance between vehicles;

[0019] Step 2. Based on the acceleration value collected in step 1, the transmission power and reception power value of the dedicated short-range communication signal between the two workshops, and the relative distance value, a set of dynamic acceleration values...

Abstract

The present invention discloses a method for positioning a road network unlicensed vehicle based on a dedicated short-range communication network. With the development of the Internet of vehicles technology, arranging dedicated short-range communication units and satellite positioning devices in vehicles to implement information sharing among a group of vehicles has become a development trend of the Internet of vehicles technology. By fully using the dedicated short-range communication network widely existing an Internet of vehicles system, the resent invention implements recognition and positioning of unlicensed vehicles, thereby providing information security service guarantee for the normal operation of the Internet of vehicles system.

Description

technical field [0001] The invention relates to a vehicle positioning technology in the intersecting field of an intelligent vehicle-road coordination system and a wireless mobile communication network, in particular to a road network hacker vehicle positioning method based on a dedicated short-range communication network. Background technique [0002] In the Internet of Vehicles system, the vehicle group establishes a vehicle ad hoc network through the vehicle-specific short-range communication unit to provide link guarantee for information interaction and information sharing between vehicles. On the basis of vehicle information sharing, the Internet of Vehicles system can implement a series of applications aimed at improving the efficiency of the transportation system, including: improving traffic safety, traffic efficiency, reducing exhaust emissions, energy consumption, etc. [0003] The vehicle self-organizing network is the basic guarantee for the normal operation of t...
