Target vehicle screening method, device and equipment for environment perception data sharing based on uwb

Abstract

The present invention provides a target vehicle screening method, device and equipment for environment perception data sharing based on UWB. Through the signal source direction of surrounding vehicles, the positional relationship between other vehicles and the vehicle can be accurately determined, thereby efficiently and accurately determining the location of the target vehicle. Target vehicles sharing environmental awareness data. At the same time, the vehicle can adjust the target area at any time according to the driving direction of the vehicle, automatically screen the vehicles within a certain range and establish data transmission, which overcomes the problem that the perception data of all surrounding vehicles can only be obtained in a large range due to inaccurate positioning, and avoids worthless Perception data sharing. The method of the invention can carry out data transmission without traditional Internet communication, and provides an extremely simple method for sharing perception data.

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
