 本发明的实施方式
为了使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明作进一步地详细描述，显然，所描述的实施例仅仅是本发明一部份实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。
图1是本发明实施例提供的一种车辆驾驶提示方法的流程图。如图1所示，该方法包括：
步骤110、获取本车的导航信息，该导航信息包括目的地、当前位置、当前行驶速度和地图信息。
本车的导航信息包括本车要到达的目的地，本车的当前位置，本车的当前行驶速度以及地图信息。
步骤120、根据导航信息生成导航图像，该导航图像包括道路指示信息，该道路指示信息包括变道指示信息，转弯指示信息和目的地指示信息。
步骤130、将导航图像叠加至现实道路并通过前挡风玻璃进行显示。
本发明实施例提供的车辆驾驶提示方法可以用于平视显示器（Head Up Display，HUD），HUD包括增强现实（Augmented Reality，AR）模块，HUD 通过AR模块将生成的导航图像叠加至现实道路并通过前挡风玻璃进行显示，以实现增强显示功能。可选地，HUD可以将导航图像叠加至驾驶员视线前方至少5米内的现实道路上。
示例地，前挡风玻璃可以设置有屏幕胶片，HUD将与现实道路相结合的虚拟导航图像投射至屏幕胶片，屏幕胶片再将HUD投射的光线反射到驾驶员眼睛，进而使驾驶员看到相应的信息。
在车辆行驶过程中，HUD能够将导航图像叠加至现实道路并通过前挡风玻璃进行显示，具体可以将变道指示信息，转弯指示信息和目的地指示信息通过前挡风玻璃进行显示，这样一来，驾驶员可以根据显示结果控制车辆执行变道操作，转弯操作和停车操作。在本发明实施例中，驾驶员可以通过观看前挡风玻璃上的信息获得导航信息，其无需将目标移开前挡风玻璃低头观看显示屏，所以驾驶员不易对路面情况分心，提高了车辆行驶的安全性。同时，该方法中生成的虚拟导航图像还与本车前方实际路况相贴合，使得驾驶员能够及时了解到更加全面，更加准确的导航信息，进而对车辆的行驶状态进行调节。
本发明实施例提供的车辆驾驶提示方法，能够获取本车的导航信息，再根据导航信息生成导航图像，之后，将导航图像叠加至现实道路并通过前挡风玻璃进行显示。其中，导航信息包括目的地、当前位置、当前行驶速度和地图信息，生成的导航图像包括道路指示信息，道路指示信息包括变道指示信息，转弯指示信息和目的地指示信息。通过该方法，驾驶员无需低头观看显示屏即可获得导航信息，所以驾驶员不易对路面情况分心，提高了车辆行驶的安全性。且导航图像与前方实际路况相贴合，使得驾驶员能够及时了解到更加全面，更加准确的导航信息。
图2本发明实施例提供的另一种车辆驾驶提示方法的流程图。该车辆驾驶提示方法可以用于HUD，在该方法中，HUD还可以通过前挡风玻璃对车辆周围的环境信息进行显示，并对相应的提示信息进行显示。如图2所示，该方法包括：
步骤210、获取本车的导航信息。
本车的导航信息包括本车要到达的目的地，本车的当前位置，本车的当前行驶速度以及地图信息。
在步骤210中，HUD可以从高级驾驶辅助系统（Advanced Driving Assistant System，ADAS）获取本车的导航信息。
通常，ADAS包括多种传感器。在车辆行驶过程中，ADAS能够随时感应车辆周围的环境，收集数据，进行静态、动态物体的辨识，侦测和追踪，并结合导航仪地图数据，进行系统的运算和分析。ADAS可以实现导航、自适应巡航、车道偏移报警、车道保持、防碰撞、自适应灯光控制、行人碰撞预警、自动泊车、交通标志识别、盲点探测、驾驶员疲劳探测和下坡控制等功能。本发明实施例中的HUD从ADAS获取本车的导航信息，以便于根据获取的导航信息生成导航图像。
步骤220、根据导航信息生成导航图像。
导航图像包括道路指示信息，该道路指示信息包括变道指示信息，转弯指示信息和目的地指示信息。
步骤230、将导航图像叠加至现实道路并通过前挡风玻璃进行显示。
在车辆行驶过程中，HUD能够将变道指示信息，转弯指示信息和目的地指示信息通过前挡风玻璃进行显示，使得驾驶员能够控制车辆执行变道操作，转弯操作和停车操作。
图3示例性示出了HUD通过前挡风玻璃显示的变道指示信息的示意图，图4示例性示出了HUD通过前挡风玻璃显示的转弯指示信息的示意图，图5示例性示出了HUD通过前挡风玻璃显示的目的地指示信息的示意图。进一步地，如图3至5所示，该方法还可以通过前挡风玻璃显示本车的当前行驶速度，行驶速度的单位为km/h（千米每小时）。
在本发明实施例中，由于HUD将导航图像叠加至现实道路并通过前挡风玻璃进行显示，所以驾驶员可以通过观看前挡风玻璃上的信息获得导航信息，无需将目标移开前挡风玻璃低头观看显示屏。且虚拟导航图像还与本车前方实际路况相贴合，使得驾驶员能够及时了解到更加全面，更加准确的导航信息。
步骤240、获取本车周围的环境信息。
在步骤240中，HUD可以从ADAS获取本车周围的环境信息。示例地，本车周围的环境信息可以包括本车周围目标障碍物的运行信息，车道线的位置信息，本车所在路段的交通标志信息，盲点探测信息等。
步骤250、根据本车周围的环境信息生成提示信息。
HUD根据获取的本车周围的环境信息生成提示信息。
在本发明实施例中，HUD获取的本车周围的环境信息可以包括多种，不同的环境信息对应的提示信息不同。下面以目标障碍物的运行信息，车道线的位置信息和路段的交通标志信息为例进行说明。
示例地，在第一种可实现方式中，本车周围的环境信息包括目标障碍物的运动信息，运动信息包括目标障碍物相对于本车的运动距离，目标障碍物包括前方障碍物和后方障碍物中的至少一个，根据环境信息生成的提示信息可以包括第一提示信息，相应地，如图6所示，步骤250中根据本车周围的环境信息生成提示信息，可以包括：
步骤251、检测运动距离是否小于指定距离。
步骤252、当运动距离小于指定距离时，生成第一提示信息。
HUD检测目标障碍物相对于本车的运动距离是否小于指定距离，当运动距离小于指定距离时，表明本车与目标障碍物的距离较近，易出现交通事故，在这种情况下，HUD生成第一提示信息，该第一提示信息用于指示目标障碍物相对于本车的运动距离小于指定距离。当目标障碍物相对于本车的运动距离不小于指定距离时，HUD则不执行第一提示信息的生成操作。其中，指定距离可以根据本车当前行驶速度以及天气情况来确定，本实施例对指定距离的大小不做限定。
示例地，目标障碍物可以为车辆或行人。车辆可以为前方车辆和后方车辆中的至少一种。行人可以为前方行人和后方行人中的至少一种。通过执行步骤251和步骤252，HUD能够在本车可能与周围目标障碍物发生碰撞时及时对驾驶员进行提示，使得驾驶员无需任何思考即可及时作出反应，达到了碰撞预警的目的。
可选地，HUD生成的第一提示信息还可以包括目标障碍物相对于本车的运动距离和行驶速度。基于该第一提示信息，驾驶员能够更加直观地了解交通外景情况。
在第二种可实现方式中，本车周围的环境信息包括车道线的位置信息，根据环境信息生成的提示信息可以包括第二提示信息，相应地，如图7所示，步骤250中根据本车周围的环境信息生成提示信息，可以包括：
步骤253、根据车道线的位置信息和本车的当前位置判断本车是否出现车道偏移。
步骤254、当本车出现车道偏移时，生成第二提示信息。
其中，第二提示信息用于指示本车出现车道偏移。
在根据车道线的位置信息和本车的当前位置判断本车是否出现车道偏移时，可以根据本车的中心与两侧车道线的距离判断。
本实施例中本车出现车道偏移指的是驾驶员“无意”偏离车道的情况。当驾驶员主动转向（即转向灯打开），或者没有明显道路区隔时，则认为驾驶员不是“无意”偏离车道，也即是，本车没有出现车道偏移，此时，HUD不执行第二提示信息的生成操作。
通过执行步骤253和步骤254，HUD能够在驾驶员无意偏离车道时及时对驾驶员进行提示，达到车道保持的目的。
在第三种可实现方式中，本车周围的环境信息包括本车所在路段的交通标志信息，根据环境信息生成的提示信息可以包括第三提示信息，相应地，步骤250中根据本车周围的环境信息生成提示信息，包括：根据本车所在路段的交通标志信息生成第三提示信息，该第三提示信息用于指示交通标志信息。
示例地，交通标志信息可以为最高时速、禁止鸣喇叭、禁止临时停车、禁止超车、禁止掉头、禁止向左转弯或慢行等。HUD根据本车所在路段的交通标志信息生成第三提示信息，以将该路段的交通标志信息及时提示给驾驶员，从而减少交通事故发生率，提高车辆行驶的安全性。
步骤260、通过前挡风玻璃显示环境信息和提示信息。
参见步骤250，示例地，当本车周围的环境信息包括目标障碍物的运动信息时，HUD通过前挡风玻璃显示目标障碍物的运动信息比如目标障碍物相对于本车的运动距离，并在检测到目标障碍物相对于本车的运动距离小于指定距离时，显示第一提示信息。图8示例性示出了后方来车且后方车辆相对于本车的行驶距离小于指定距离（如2米）所对应的第一提示信息的显示示意图。图9示例性示出了前方车辆相对于本车的行驶距离小于指定距离（如2米）所对应的第一提示信息的显示示意图。图10示例性示出了前方行人相对于本车的距离小于指定距离所对应的第一提示信息的显示示意图。如图8至图10所示，该方法还可以通过前挡风玻璃显示本车的当前行驶速度。
当本车周围的环境信息包括车道线的位置信息时，HUD通过前挡风玻璃显示车道线的位置信息，并在本车出现车道偏移时显示第二提示信息。图11示例性示出了本车出现车道偏移对应的第二提示信息的显示示意图。
当本车周围的环境信息包括本车所在路段的交通标志信息时，HUD通过前挡风玻璃显示交通标志信息和第三提示信息。图12示例性示出了最高时速对应的第三提示信息的显示示意图，此时，本车的行驶速度为40km/h，最高时速为30km/h，驾驶员获得该第三提示信息后会及时控制车辆减速。
通常，当遇到雨雪，雾霾等恶劣天气时，车辆周边会存在盲点区域。而盲点区域会对车辆安全行驶造成影响。为了避免盲点区域对车辆安全行驶造成影响，可选地，ADAS可以包括用于探测盲点区域的毫米波雷达，HUD还用于从ADAS获取盲点区域的数据，再根据该数据生成第四提示信息，并通过前挡风玻璃显示该第四提示信息，从而将盲点区域提示给驾驶员。图13示例性示出了盲点区域对应的第四提示信息的显示示意图。同样的，该方法还可以通过前挡风玻璃显示本车的当前行驶速度：60 km/h。
可选地，在本发明实施例中，HUD还用于将本车的车辆信息通过挡风玻璃进行显示。示例地，车辆信息可以包括燃油水平、温度和英里数等信息。
在本发明实施例中，为了便于驾驶员获得的前挡风玻璃上的显示结果，可以使视场角（Field of View，FOV）大于或等于10°，显示内容的分辨率可以为800*480，显示内容的亮度可以大于或等于10000cd/m（坎德拉/平方米）。HUD所占用的空间小于或等于5L（升）。
综上所述，本发明实施例提供的车辆驾驶提示方法，能够获取本车的导航信息，再根据导航信息生成导航图像，之后，将导航图像叠加至现实道路并通过前挡风玻璃进行显示。其中，导航信息包括目的地、当前位置、当前行驶速度和地图信息，生成的导航图像包括道路指示信息，道路指示信息包括变道指示信息，转弯指示信息和目的地指示信息。通过该方法，驾驶员无需低头观看显示屏即可获得导航信息，所以驾驶员不易对路面情况分心，提高了车辆行驶的安全性。且导航图像与前方实际路况相贴合，使得驾驶员能够及时了解到更加全面，更加准确的导航信息。且该方法还能够通过前挡风玻璃显示环境信息和相应的提示信息，使驾驶员直观地了解交通外景情况。
需要说明的是，本发明实施例提供的车辆驾驶提示方法的步骤的先后顺序可以进行适当调整，车辆驾驶提示方法步骤也可以根据情况进行相应增减。任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化的方法，都应涵盖在本发明的保护范围之内，因此不再赘述。
