Research On Collaboration Control Algorithms For Intersection Platoon Based On Miniature Traffic Intersection Environment

In recent decades,with the increase number of vehicles,because of this,the incidence of traffic accidents also increased sharply,and the economic losses can not be estimated.Many countries make a great effort to research traffic safety.The traditional body safety technology has been unable to meet the needs of traffic safety capacity.Intelligent vehicle platoon has become a hot topic in the field of automotive safety,it is to meet the driver's demand for transportation,and hands free,make the driving process out of human operation.This research not only increases transportation discharge but also avoids traffic accidents caused by human factors.Intelligent vehicle platoon using fast response time and strong stability of computer technology,make the platoon travel for small workshop distance,high traffic flow,and low accident rate.It is become the emphases for research of intelligent transportation in the future.In this paper,for the intersection traffic without traffic lights,the control algorithms for collaborating intersection platoon is researched car-to-car communication technology.Due to the complex environment of experiment platform,difficult to build and low safety factor,using hardware-in-the-loop simulation technology and the Intelligent Traffic Engineering Technology Center to research this control algorithm.The main works of this dissertation are as follows:First,the cooperative vehicle infrastructure system is built by hardware-in-the-loop simulation technology.Then,the software and hardware system about this experimental platform is also introduced.The main part is structures of miniature car.Second,researching control algorithms for collaborating intersection platoon:establish mathematical model,longitudinal control model and wishbone model.Write the corresponding control algorithm.Finally,effectiveness and stability of the system were proved through simulation and experiments.In order to provide a theoretical basis for future research on platoon coordinated control.
