基于改进型虚拟拖车链模型的车辆跟踪算法

摘要

车辆跟踪在缓解交通拥堵和减少交通事故中发挥着积极作用。如何使得后车能够平滑地靠近，并且具备良好的收敛速度，是车辆跟踪需要解决的两个重要问题。提出了一种改进型虚拟拖车链模型，运用 Matlab 仿真软件将改进型虚拟拖车链模型应用到车辆跟踪算法中，最终使得后车可以准确平稳地到达指定位置。研究结果为进一步开展车辆跟踪算法的研究奠定基础。%Vehicle tracking plays a very positive role in alleviating traffic congestion and reducing traffic accidents.More and more researchers focuse their attentions on vehicle tracking.There are two important problems to be solved in vehicle tracking.One is how to make the car approaching smoothly.And the oth-er is how to make the convergence faster.This article presents an improved virtual trailer chain model.At last,this article uses Matlab and the algorithm based on the improved virtual trailer chain model for sim-ulation.The result is that the tracking car can reach the designated position accurately and smoothly.The research results lay the foundation for the further research of the vehicle tracking algorithm.
