UWB-based target vehicle screening method, device and equipment for sharing environmental perception data

Abstract

The invention provides a UWB-based target vehicle screening method, device and equipment for sharing the environmental perception data. The position relation between other vehicles and the vehicle can be accurately determined through the signal source directions of the surrounding vehicles, and therefore the target vehicle capable of sharing the environmental perception data can be efficiently and accurately determined. Meanwhile, the vehicle can adjust the target area at any time according to the driving direction of the vehicle, the vehicles in a certain range are automatically screened, data transmission is established, the problem that as positioning is not accurate enough, only sensing data of all surrounding vehicles can be obtained in a large range is solved, and sharing of valuable sensing data is avoided. According to the method provided by the invention, data transmission can be carried out without traditional internet communication, and a very simple and convenient perception data sharing method is provided.

Description

technical field [0001] The present invention relates to the technical field of unmanned driving, in particular to a target vehicle screening method, device and equipment for sharing environment perception data based on UWB. Background technique [0002] In unmanned driving technology, the vehicle needs to sense the environment through various sensors and roadside equipment carried by itself, so as to provide decision support for controlling the safe driving of the vehicle. It is an important method to improve the accuracy of environmental perception by obtaining the environmental perception data of surrounding vehicles for its own use, but for the vehicle itself, not all the data perceived by the surrounding vehicles are valuable, such as from the vehicle The environmental data sensed by the vehicles directly behind and on both sides of the directly behind is not helpful to the driving of the vehicle. Obtaining these data will only increase the amount of data transmission. T...

It is an important method to improve the accuracy of environmental perception by obtaining the environmental perception data of surrounding vehicles for its own use, but for the vehicle itself, not all the data perceived by the surrounding vehicles are valuable, such as from the vehicle The environmental data sensed by the vehicles directly behind and on both sides of the directly behind is not helpful to the driving of the vehicle. Obtaining these data will only increase the amount of data transmission. Therefore, it is necessary to screen valuable target vehicles to only interact with valuable vehicles. of vehicle build data sharing
