Abstract

The invention relates to a traffic flow distributed cooperative formation control method based on adaptive event triggering. The method comprises the steps: performing an obstacle avoidance control step; to be specific, building an unmanned vehicle linear kinetic model, and carrying out obstacle avoidance controlling with a neighbor vehicle based on global coordinate position information of an unmanned vehicle and a neighbor unmanned vehicle; performing a leader vehicle observation step; to be specific, acquiring state information of the leader vehicle by using a distributed observer based onadaptive event triggering; and performing a path following step; to be specific, adjusting the state information of the unmanned vehicle according to the state information of the leader vehicle by using a vehicle cooperative controller triggered based on an adaptive event. Compared with the prior art, the traffic flow distributed cooperative formation control method has the following advantages: with introduction of an event triggering mechanism, the communication load between vehicles is reduced and cooperative formation control over traffic flow is realized.

Description

technical field [0001] The invention belongs to the technical field of intelligent traffic control systems, and relates to a multi-vehicle communication control method, in particular to a vehicle flow distributed cooperative formation control method based on adaptive event triggering. Background technique [0002] Coordinated formation control of vehicle flow in intelligent traffic control technology is its core. The safe distance between vehicles is the basic problem of coordinated formation control of vehicle flow, which can constitute vehicle maneuvers such as changing lanes, avoiding obstacles, and following vehicles. Through the cooperative formation control method of vehicle flow, the road traffic capacity can be effectively increased, traffic congestion can be alleviated, and fuel pollution can be reduced. [0003] Vehicle flow cooperative formation control uses the method of distributed observation control, which can better avoid the use of global information, reali...
