Abstract

The embodiment of the invention discloses a sensing base station in a road traffic environment and a message sending method and device of the base station. The sensing base station comprises a local map data maintenance module which is used for obtaining local map data in a target region range from a map data server in a customized manner, wherein the target area range corresponds to a sensing area range of the sensing base station; and a local map data sending module which is used for generating a first message according to the local map data and broadcasting the first message according to afirst frequency, and the first message comprises the local map data and corresponding data content type field information. Through the embodiment of the invention, resources can be saved, the cost isreduced, and meanwhile, more accurate auxiliary driving information is realized.

Description

technical field [0001] The present application relates to the technical field of vehicle-road coordination, and in particular to a sensing base station in a road traffic environment and a method and device for sending messages thereof. Background technique [0002] In the fields of autonomous driving and intelligent transportation, highly intelligent autonomous vehicles can effectively perceive their surrounding environment, obtain information such as the type, position, orientation, size, and speed of nearby targets, and make reasonable decisions based on their own driving status. Driving decision-making completes the work of vehicle driving, thereby replacing manual driving labor and realizing a highly automated driving process. [0003] At present, there are two main types of autonomous driving perception systems: vehicle-mounted sensor network perception and vehicle-road collaborative perception. In the way of on-board sensor network perception, self-driving cars need t...
