无人驾车车轨迹跟踪控制，是目前社会研究的重点。本程序代码实现matlab联合carsim进行联合仿真，实现追踪给定轨迹。经测试，在低速状态，追踪效果很理想。(Unmanned driving vehicle trajectory tracking control, is currently the focus of social research.This procedure code realization of matlab joint carsim joint simulation, track the given trajectory.After the test, in low speed condition, tracking effect is very ideal.)
