技术领域
本公开涉及通过安全网络的点对点或车辆对车辆通信，并且更具体地涉及通过专用无线网络传送地理标记和时间戳数据。
背景技术
自主车辆是下一代机动性车辆，并且将具有超过现有车辆的先进安全特征。作为这些新车辆的安全特征的部分，每个车辆可以具有点对点通信，使得在同一道路上彼此相对行驶的或在同一道路上在相同方向上行使但相隔一段距离的车辆之间可以共享行驶的道路状况、能见度和其他特征。有利的是，每个车辆都被告知道路状况，使得可以增强安全性或采取替代路线。一直需要对于自主车辆具有改进的点对点通信系统，该改进的点对点通信系统用于通过安全网络传输和接收指示至少车辆全球定位位置、道路状况、行驶能见度和车辆遥测的安全地理标记和时间戳数据。
发明内容
在本公开的某些方面，提供了一种通过安全无线网络的车辆的点对点或车辆对车辆通信系统。系统服务者采集被地理标记、标记时间戳并通过无线网络传送到专用云的车辆遥测、行驶能见度和/或道路状况数据。该地理标记和时间戳数据可以从多个车辆收集并且可以在多个车辆之间共享。数据可以向驾驶员显示或由自动制动系统或自主驾驶系统使用以适当地控制车辆。
在本公开的某些其他方面，提供了一种使用车辆的点对点通信系统来控制自主车辆的方法。
附图说明
图1是配备有导航系统、摄像机、用以检测道路状况的传感器以及蜂窝电话或Wi-Fi能力的车辆的图示。
图2是在路段上通过蜂窝网络向专用云传输数据的车辆的图示。
图3是示出了根据一个实施方式生成安全地理标记数据的方法的流程图的图示。
图4是示出了根据一个实施方式广播安全地理标记数据的流程图的图示。
图5是示出了根据一个实施方式用于读取安全地理标记数据的方法的流程图的图示。
图6是示出了根据一个实施方式接收安全地理标记数据的流程图的图示。
图7是路段上的两个车辆的图示，其中一个车辆传输数据而另一车辆接收数据。
具体实施方式
现在转到附图，其中相似的附图标记表示相似的特征，图1示出了车辆10，具有导航系统12、能够传输指示道路状况和车辆遥测的信号的传感器14、安装在车辆上(可选地前方和后方两者)用于传输能见度状况的摄像机16以及可选地控制自主驾驶系统20的车载计算机18。车辆10还可以包括自动制动系统22。车载计算机或“控制器”具有存储器，其可以是FLASH、RAM、ROM、PROM、EPROM、EEPROM或在其中储存信息和指令的任何其他存储器。
已经描述了合适的自主车辆，本公开还包括用于通过安全网络的点对点或车辆对车辆通信的至少一种方法，使得由分隔一距离的车辆可以彼此通信。这样的车辆可以在同一或相对的方向上行驶。
现在转向图2，示出了在路段26上通过蜂窝网络30向专用云32传输数据28的车辆10。该车辆可以是如前所述的自主车辆，或者其可以是没有自主驾驶系统的车辆。车辆计算机创建使用无线网络诸如Wi-Fi或蜂窝电话网络保护的匿名地理标记数据28。蜂窝电话网络向专用云网络32传输匿名地理标记数据。所传输的数据储存在专用云中，以供订户或其他有权访问专用云的人访问。
现在转向图3，其中示出了根据一个实施方式示出创建安全地理标记数据38的一种方法36的流程图的图示。导航系统确定车辆的全球定位位置40。计算机系统收集车辆遥测42并且传感器诸如摄像机收集道路状况44，诸如危险、交通放慢或停止等。计算机具有在数据收集的每个间隔处实时创建时间戳46的时钟。计算机生成安全数据交易48，以及然后通过蜂窝网络或Wi-Fi在50广播地理标记数据。转到图4，安全地理标记数据包括经由蜂窝电话(可选地车载蜂窝电话)或Wi-Fi 51向专用云传输的GPS数据41、车辆遥测43、来自传感器和摄像机45的信息以及用于对数据标记时间戳的时钟功能47。
如图5所示，使用储存在专用云中的数据的车辆首先在52处确定自身的GPS位置和传输车辆。接收车辆将定义搜索区域和时间窗口54，并且然后请求区域信息56。在58处解析接收的数据，并且然后计算机根据接收的数据采取行动60。如图6所示，所请求的数据从专用网络传输出到车载蜂窝或Wi-Fi接收器。计算机系统在62处解析可以与车辆导航系统、自动制动系统和自主驾驶系统共享的地理标记和时间戳数据。这些系统中的每个都可以使用所接收的数据来基于所接收的数据改变或管理车辆操作。
现在转向图7，将根据一个非限制性实施方式描述点对点或车辆对车辆通信系统64。示出了在道路70上在它们各自的车道72和74朝向彼此行驶的车辆66和68。在该描述中，车辆68创建“交易数据”76，其可以包括其地理标记位置78的“交易数据”76、车辆遥测80、能见度状况82、所遇到或所感测到的道路危险84和对于每个传输数据的时间戳86。该交易数据76经由蜂窝网络传输。接收车辆66将定义搜索区域90，定义其已接收的时间戳窗口92，请求数据94，读取数据96，验证数据98以确保其来自被授权经由专用网络进行传送的车辆，解析数据100为了由车辆系统使用，并且然后计算机可以根据接收的数据采取行动102，诸如通过进行自主驾驶或在车辆沿其行驶路径行进时激活自动制动系统来控制或改变车辆66的操作。
以上描述意在说明而非限制。应该参考所附权利要求以及等同物的全部范围一起来确定本发明的范围。预期并打算的未来的发展将在本领域中发生，并且所公开的装置、套件和方法将被结合到这样的未来实施方式中。因此，本发明能够进行改变和变化，并且仅受所附权利要求的限制。
