In recent years, with the development of the micro-electronics technique, the price of GPS receiver have been greatly falling , and as a result of the United States closing SA to stop limiting the public position accuracy of GPS , the GPS positioning accuracy have improved greatly in public field. All this consumedly promote the development of GPS in public field, and especially in the vehicle navigation field , GPS shows its superiorly navigation performance.

近年来随着微电子技术的发展使得GPS接收机的价格大幅度下降，同时美国提前关闭SA停止对民间用户精度的限制使得GPS民用定位精度有了很大的提高，这大大促进了GPS在民用领域的发展，尤其是在车辆导航领域，GPS系统充分展示了它那优越的导航性能。

Firstly,subgoal choosing is optimized by using heuristic function according to the window's information,it is local environment's information,which is obtained by camera.Then navigation behavior is divided into GO TO TARGET behavior and OBSTACLE AVOIDANCE behavior,their behaviorial states and behaviorial modes dynamics models are established,and then one autonomous local path planning online is implemented using navigation behavior dynamics model in a single window.Connecting a series of local paths according to continuity,the robot accomplishes one global planning ultimately.

首先根据所获得的窗口信息，采用启发式函数进行局部子目标优化选择；然后将路径规划问题即导航行为分解为趋于目标行为和避障行为，并对这两种行为分别建立了行为状态和行为模式动力学模型；在此基础上，以窗口为单位，利用导航行为动力学模型进行在线自主路径规划；将一系列窗口中的规划轨迹按照连续性条件首尾相接，最终完成了一条全局规划任务。
