Traffic method and system of networked automatic driving vehicle at traffic light intersection

Abstract

The invention discloses a traffic method and system of a networked automatic driving vehicle at a traffic light intersection, belongs to the technical field of networked communication, and provides scene classification and a solution method of each scene in a targeted manner for the actual current situation of a future intelligent traffic transition period. A first scene classification is that SPAT messages sent by a traffic light RSU can be normally received. A second scene classification is that the SPAT message sent by the traffic light RSU is not received, but the traffic light information can be detected by a vehicle-mounted camera. A third scene classification is that the SPAT message sent by the traffic light RSU is not received, the traffic light cannot be detected by the vehicle-mounted camera, the traffic light can be detected by surrounding vehicles, and the V2X function is achieved. A fourth scene classification is that when the SPAT message sent by the traffic light RSU is not received, the vehicle-mounted camera cannot detect the traffic light, and the surrounding vehicles cannot detect the traffic light or do not have the V2X function.

Description

technical field [0001] The invention belongs to the technical field of network-connected communication, and more specifically relates to a method and a system for passing a network-connected self-driving vehicle at a traffic light intersection under a hybrid smart traffic scene. Background technique [0002] At present, most of the autonomous driving solutions are single-vehicle intelligence, that is, they only rely on cameras and radars for environmental perception. Most of the related applications in the field of Internet of Vehicles are information service and early warning functions. Specifically, in the traffic light intersection scene, the general solution for self-driving vehicles is to rely on cameras to identify traffic lights and help pass. Networked vehicles with vehicle to everything (V2X) function can obtain traffic light status by receiving information sent by traffic light Road Side Unit (RSU), and realize red light warning and other functions.

AI Technical Summary

Problems solved by technology

However, the market prospect of early warning functions using the above scheme is limited, and the long-term market potential is insufficient

Secondly, the scheme of only using RSU to transmit traffic light messages is greatly limited by the scope of infrastructure

However, the cost of laying out the Internet of Vehicles infrastructure is huge. At present, only some places in China have pilot projects, and even if RSUs are widely promoted to all parts of the country in the future, it is difficult to ensure that every traffic light is equipped with RSUs.
