Embodiment

[0034] The preferred embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0035] The present invention proposes a signal light intersection intelligent traffic system based on V2X communication, that is, the intersection intelligent traffic system, which is especially suitable for self-driving vehicles. When driving on urban roads, self-driving vehicles will inevitably pass through intersections with signal lights. When the vehicle encounters this situation, the vehicle equipped with the V2X communication-based intelligent traffic system for vehicles automatically passing through the signal light intersection will obtain the signal light information through V2X, and control the vehicle to pass through the signal light intersection safely and autonomously. The system ensures the normal passage of self-driving vehicles at intersections with signal lights in cities, enables vehicles to make behavioral decisions and c...

Abstract

The invention discloses an intelligent passing system for a signal lamp road junction based on V2X communication. The intelligent passing system comprises a signal lamp data collection module, a V2X communication roadside system, a cloud data communication platform, a V2X communication vehicle-mounted system and a vehicle-mounted controller, wherein the signal lamp data collection module collectsstate information of a signal lamp; the V2X communication roadside system sends collected signal lamp relevant information to the cloud data communication platform; the cloud data communication platform loads map information of each signal lamp road junction, performs fusion on obtained signal lamp information and map data of corresponding road junctions, judges a motion state of a vehicle, and sends relevant information of a signal lamp at a front target road junction of a vehicle motion; the V2X communication vehicle-mounted system receives the information, send by the cloud data communication platform, of the signal lamp at the front road junction, and sends the information to the vehicle-mounted controller; and the vehicle-mounted controller is used for receiving the information of thesignal lamp and obtaining environment perception information, and performs behavior decision and control according to obtained phase position and timing information of the signal lamp. A vehicle is automatically controlled according to a state of a signal lamp to drive in terms of a traffic rule, so the passing efficiency at a road junction is improved.

Description

technical field [0001] The present invention relates to an intelligent traffic method at a signal light intersection, in particular to a V2X communication-based intelligent traffic system and method for a self-driving vehicle at a signal light intersection. Background technique [0002] With the development of automotive electronics, autonomous driving technology is gradually becoming mature. Due to the complexity of urban roads, traffic and environment, compared with closed areas and expressways, urban autonomous driving is more complex in application scenarios and more difficult in technology development. [0003] The current rapid increase in the number of vehicles has caused traffic congestion, complex vehicle application scenarios, and traffic safety and efficiency issues to become more serious. With the development of communication technology, the "vehicle-X" (X-vehicle, road, people, cloud, referred to as V2X) system based on dedicated short-range communication (DSRC...
