specific Embodiment approach 1

[0031] Specific implementation mode one: the following combination Figure 1 to Figure 3 Describe this embodiment, a kind of self-driving vehicle unsignalized intersection coordinated traffic control system described in this embodiment includes: vehicle agent VA and intersection agent IA;

[0032] The vehicle agent VA is set on the unmanned vehicle to detect whether the unmanned vehicle where it is located has entered the unlit intersection area. The agent IA establishes a wireless communication connection, and sends a request signal and real-time status information of the vehicle to the intersection agent IA;

[0033] The intelligent body 1A of the intersection is arranged in the intersection area without lights, establishes a wireless communication connection with the vehicle intelligent body VA that sends the request signal, and correspondingly receives the real-time status information of the vehicle intelligent body VA;

[0034] The intersection agent IA is also used to d...

Abstract

The invention discloses an automatic driving vehicle non-signalized intersection coordination passing control system, which belongs to the technical field of vehicle automatic driving. The problem that an automatic driving vehicle is poor in safety at an intersection without signal lamps is solved. The system comprises a vehicle agent VA and an intersection agent IA, the vehicle agent VA is arranged on an unmanned vehicle and used for detecting whether the unmanned vehicle where the vehicle agent VA is located enters the non-lamp intersection area or not, and if the unmanned vehicle enters the non-lamp intersection area, a passing request signal and real-time state information of the vehicle are sent to the intersection agent IA of the corresponding non-lamp intersection area; and the intersection agent IA is arranged in a light-free intersection area, establishes wireless communication connection with the vehicle agent VA which sends the passing request signal, and receives real-time state information of the vehicle agent VA. The system is suitable for the unmanned vehicle to pass through the non-signal intersection.

Description

technical field [0001] The invention belongs to the technical field of vehicle automatic driving. Background technique [0002] A non-signal controlled intersection involves vehicles from different entrance directions. They may request to pass through the intersection at the same time, which will inevitably cause potential conflicts in some areas within the intersection range and increase the risk of collision accidents. For human driving, in the face of this type of intersection, human drivers will automatically "negotiate" to adjust their driving behavior, and then pass through the intersection in an orderly manner, usually without causing traffic congestion. Accidents happen. However, for self-driving vehicles, unsignalized intersections with "potential conflicts" constitute a very complex traffic scenario, requiring a high level of intelligence to ensure safe passage. In addition, multiple self-driving vehicles at unsignalized intersections need effective coordination ...
