Problems solved by technology

However, in this system, the vehicle side is only equipped with a 4G communication module. Due to the large transmission delay of 4G, if the following distance is relatively short, the vehicle will not have enough time for braking and other controls.
On the other hand, the roadside end only transmits traffic event information and signal light information to the cloud, and does not perceive more detailed information of the driving environment through image-rich information.

Abstract

The invention discloses a road-vehicle fusion urban road global perception method based on 5G. The method comprises vehicle side environment perception data processing, road side environment perception data processing and road-vehicle global perception data processing. Through the technical scheme of the invention, the obstacle information (position, speed and category), signal lamp information and traffic event information of a vehicle driving area or a predicted arrival area can be obtained, and more accurate and richer global perception information is provided while low delay is ensured.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and in particular relates to a 5G-based urban road-vehicle fusion global sensing method. Background technique [0002] The rapid development of the automobile market in the world has increased the number of automobiles. Car travel has brought convenience to people's lives, but it has also caused frequent traffic accidents, urban traffic congestion, increased automobile energy consumption, and environmental pollution. Today, the traffic problem has become a global problem that all countries have to face up to and pay close attention to. [0003] In order to improve the traffic environment, governments around the world and experts and scholars are actively exploring ways to effectively solve the above traffic safety problems, and intelligent transportation systems have emerged as the times require. The automatic driving system is an important subsystem in the intelligent transpo...
