随着道路交通基 设施建设的发展, 每年都会新铺设大量的道路, 这些 道路互相交织, 形成复杂的道路交通网。 在道路上设立标牌、 依靠驾驶员的 记忆和方向感已无法保证车辆行驶路线的正确和最优化, 此时往往需要借助 于专业的导航设备来进行线路选择和指引。
导航设备主要依赖于专业地图和车辆位置定位技术, 其基本原理是通过 预先设定出发点、 目的地以及导航策略, 根据专业地图中存储的道路及各种 设施信息, 计算得到出发点和目的地之间的所有可选路线, 然后根据导航策 略选取一条该策略下的最优线路, 并在车辆行驶过程中通过对车辆位置进行 定位, 对车辆的试行路线及时给出指引提示。 导航过程主要分为两个阶段: 路线选取和标识阶段、 以及车辆行驶过程中的导航阶段。 其中在导航阶段主 要完成车辆的随动定位并在地图上标识, 如果发现车辆实际的行驶路线与预 先设定的路线不相同, 需要重新进入路线选取和标识阶段, 按照车辆的实际 位置重新计算和选取路线。 另外, 在导航阶段还需完成对重要路段(路口、 岔道等) 的提前提示。
对于导航设备在线路引导的作用来看, 在正常路段(如: 道路方向明确、 没有其他岔路口)导航设备的作用较小, 关键是在遇到重要路段的提前提示, 提前提示的准确性和真实性是车辆能否按照选定线路进行行驶的重要保证。 目前, 在处理重要路段的提示方式上一般采用语音和图像的方式, 其中图像 主要根据专业地图中所存储的信息, 进行路段图像的绘制, 通过这种方式绘 制的图像与驾驶员实际看到的道路情况有比较大的差异; 而且导航信号只能 定位车辆的平面位置, 对立体交通线路能够提高的帮助较小, 因此在很多复 杂路段, 驾驶员此时仍然需要依赖于道路标牌和方向感来选择线路, 影响了 导航设备的实际功用。 发明内容
