Embodiment Construction

[0022] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.

[0023]The present invention provides a multi-vehicle cooperative driving planning method based on distributed group intelligence learning in order to reduce the requirements on the computing capability and communication capability of the vehicle during multi-vehicle coordination and ensure the maximum benefit of the vehicle itself. The realization of the technology of the present invention involves technologies such as evolutionary game theory and multi-agent deep reinforcement learning. Evolutionary game is used to model the process of continuous game between vehicles in routing planning. When the game state forms a stable situation, that is, each vehicle gets the routing decision that maximizes its own interests, and the Nash equilibrium in the game is formed. Using the powerful policy learning ability of deep reinforcement learning to model the coo...

Abstract

The invention discloses a multi-vehicle collaborative planning method based on crowd-sourcing learning, and belongs to the technical field of multi-vehicle-road collaborative decision making. According to the invention, the edge server is utilized to reduce the requirements of the computing capability and the communication capability of the vehicle; the evolutionary game is used for modeling the process of continuous game between vehicles in routing planning, and when the game state forms a stable situation, each vehicle obtains a routing decision with maximum own benefit; an intersection passing driving decision-making module is deployed on each vehicle, the vehicle is regarded as an independent decision-making individual, and a cooperative driving behavior of multiple vehicles at the intersection is modeled by using the powerful strategy learning capability of deep reinforcement learning; a traffic situation prediction module is calculated and deployed at the roadside edge, and the traffic situation perception under the limited visual field of vehicles is expanded by using the communication capability of multiple vehicles and roads. According to the invention, different aspects of road resources are optimized, space-time utilization of the intersection is optimized, space-time utilization of road resources around the intersection is optimized, and throughput of the intersection is increased.

Description

technical field [0001] The invention relates to the technical fields of road traffic network and multi-vehicle coordination, in particular to a method for multi-vehicle coordination planning based on distributed group intelligence learning. Background technique [0002] The limited urban traffic space resources and the sharp increase of motor vehicles have broken the fragile balance between supply and demand of roads, leading to traffic congestion. Therefore, how to coordinate the driving trajectory of vehicles, make full use of limited road resources, improve traffic efficiency, and alleviate the current situation of road traffic congestion is a current research direction. [0003] Vehicle routing planning has been proven to be an effective way to alleviate urban traffic congestion. Benefiting from intelligent transportation systems and intelligent networked vehicles, routing planning technology has evolved from static routing to dynamic routing based on real-time traffic ...
