Node information acquisition device and method, and inter-vehicle topological structure acquisition device and method

Abstract

The embodiment of the invention provides a node information acquisition device and method, and an inter-vehicle topological structure acquisition device and method. The node information acquisition device comprises: an image collection unit, configured to acquire image information of peripheral vehicles adjacent to a node vehicle; a distance detection unit, configured to measure the distances and directions between the node vehicle and the peripheral vehicles; a locating unit, configured to acquire the position information of the node vehicle; and a processor unit, configured to identify the identity of the peripheral vehicles according to the image information of the peripheral vehicles, and construct node information according to the identity, the distances, the directions and the position information. According to the embodiment of the invention, an inter-vehicle topological structure during road driving can be acquired to support more applications of the Internet of Vehicles.

Description

technical field [0001] The invention relates to vehicle technology, in particular to a device for obtaining node information, a device for obtaining inter-vehicle topological structure and a method. Background technique [0002] With the development of vehicle electrification and digitalization, more and more vehicles are equipped with network connection functions. Based on various network connection functions, various connection technologies between vehicles and vehicles, vehicles and infrastructure, or vehicles and people have also been widely developed, and various objects (vehicles, infrastructure, people) can communicate with each other. Send various types of information. When sending information, the sender needs to choose the identity of the recipient, such as vehicle license plate number, vehicle electronic identification (for example, uniquely specified network address), etc., to ensure that the information can be correctly conveyed and received. In this way, a ch...

Problems solved by technology

In this way, a channel for sending information cannot be established between vehicles that have not exchanged identity information, which limits the network application between vehicles

For example, when the vehicle in front observes a dangerous situation, because it does not know which vehicles are around, let alone the identity of the surrounding vehicles, it is impossible to warn the surrounding "unfamiliar" vehicles through the network between vehicles. Cannot effectively prevent the occurrence of serial accidents
