应该理解，图1中的无人车、网络和服务器的数目仅仅是示意性的。根据实现需要，可以具有任意数目的无人车、网络和服务器。
继续参考图2，示出了根据本申请的用于推送信息的方法的一个实施例的流程200。该用于推送信息的方法，包括以下步骤：
步骤201，确定通信连接的无人车的车辆信息。
在本实施例中，用于推送信息的方法的执行主体(例如图1所示的服务器101)可以确定通信连接的无人车的车辆信息。其中，车辆信息包括无人车行车路线信息。其中，上述无人车行车路线信息，可以是能够连接形成无人车的行车路线的至少一个位置坐标的集合。作为示例，无人车行车路线信息可以为{L1，L2，L3，L4}。其中，L1，L2，L3，L4均为位置坐标。需要指出的是，在无人车行车路线信息为{L1，L2，L3，L4}时，所形成的无人车的行车路线可以为L1-L2-L3-L4。
在本实施例中，执行主体可以通过如下方式确定无人车的车辆信息：首先，接收通信连接的无人车发送的播放内容获取请求。其中，播放内容获取请求包括无人车行车路线信息和无人车身份标识信息。然后，将所获取的播放内容获取请求中的无人车行车路线信息确定为无人车的无人车行车路线信息。
在本实施例的一些可选的实现方式中，车辆信息还包括车辆类型信息。此时，执行主体还可以通过如下方式确定无人车的车辆信息：
第一步，接收无人车的路线制定请求信息，路线制定请求信息包括无人车的无人车身份标识信息、起点信息和终点信息。
在本实施例中，起点信息可以是用于表征路线的起点的各种信息。终点信息可以是用于表征路线的终点的各种信息。可选地，起点信息可以是起点的位置坐标，以及终点信息可以是终点的位置坐标。
第二步，根据无人车身份标识信息确定无人车的无人车车辆类型信息，以及根据起点信息和终点信息确定无人车的无人车行车路线信息。这里，上述无人车车辆类型信息可以是用于表征无人车的车辆类 型的各种信息。作为示例，上述无人车车辆类型信息可以为字符组“bus”，用于表征无人车的车辆类型为公交车。另外，上述无人车身份标识信息可以是用于表征无人车身份的各种信息。作为示例，无人车身份标识信息可以是数字“1”，用于表征无人车身份为编号为1的无人车。
在本实施例中，执行主体可以采用无人车身份标识，从预先构建的身份标识-车辆类型对应关系表中查找到无人车的无人车车辆类型。其中，身份标识-车辆类型对应关系表可以是技术人员基于对大量的身份标识和车辆类型的统计而预先制定的、存储有多个身份标识与车辆类型的对应关系的对应关系表。
在本实施例中，执行主体可以采用起点信息和终点信息从预先构建的起始点-路线对应关系表中查找到无人车行车路线信息。其中，起始点-路线对应关系表可以是技术人员基于对大量的起点信息、终点信息和路线信息的统计而预先制定的、存储有多个起点信息、终点信息和路线信息对应关系的对应关系表。执行主体也可以采用起点信息、终点信息和路径规划算法，计算得到无人车行车路线信息。其中，路径规划算法可以是迪杰斯特拉算法(Dijkstra's Algorithm)，也可以是A*算法(A-star algorithm)，还可以是其他用于规划起点与终点间的路径的算法。
步骤202，根据车辆信息，从预先存储的待播放内容集合中，筛选出与车辆信息相匹配的待播放内容，存入待播放内容子集合。
其中，预先存储的待播放内容集合中的待播放内容可以是音频，也可以是视频，还可以是其它形式的可以播放的内容。需要指出的是，在存入待播放内容之前，待播放内容子集合可以为空集。
在本实施例中，执行主体可以通过如下步骤得到待播放内容子集合：首先，采用无人车行车路线信息，从预先存储的关联信息表中查找到与无人车行车路线信息对应的待播放内容的编号。然后，根据查找到的待播放内容的编号从待播放内容集合中查找待播放内容，存入待播放内容子集合。其中，关联信息表可以是技术人员基于对大量的行车路线信息和待播放内容的编号的统计而预先制定的、存储有多个 行车路线信息和待播放内容的编号的对应关系的对应关系表。
在本实施例的一些可选的实现方式中，车辆信息还包括车辆类型信息。无人车行车路线信息包括至少一个无人车站点对应的无人车站点信息集合，以及待播放内容集合中的待播放内容关联有站点信息和车辆类型信息，以及根据车辆信息，从预先存储的待播放内容集合中，筛选出与车辆信息相匹配的待播放内容，存入待播放内容子集合，包括：根据无人车车辆类型信息，从待播放内容集合中查找到与无人车车辆类型信息相匹配的至少一条待播放内容；对于无人车站点信息集合中的无人车站点信息，从至少一条待播放内容中选取与该无人车站点信息相匹配的待播放内容，将所选取的待播放内容存入待播放内容子集合。
在本实施例中，其中，无人车站点可以是技术人员预先设定的位置点。无人车站点信息可以包括但不限于站点名称和站点位置坐标。
在本实施例中，执行主体还可以通过如下步骤得到待播放内容子集合：
第一步，采用无人车车辆类型信息，对待播放内容集合中的待播放内容进行筛选。这里，将无人车车辆类型信息，与待播放内容集合中的每个待播放内容进行比较，若该待播放内容所关联的车辆类型信息与无人车车辆类型信息相匹配，则选取该待播放内容。如此，可以得到至少一个待播放内容。其中，待播放内容所关联的车辆类型信息与无人车车辆类型信息相匹配，可以是指二者相同，也可以是指二者相应。作为示例，若待播放内容所关联的车辆类型信息是字符“B”，无人车车辆类型信息是字符组“bus”，字符“B”与字符组“bus”所表征的车辆类型均为公交车，则可以认为待播放内容所关联的车辆类型信息与无人车车辆类型信息相应。此时，待播放内容所关联的车辆类型信息与无人车车辆类型信息相匹配。
第二步，采用无人车站点信息集合中的无人车站点信息，对第一步所得到的至少一个待播放内容进行进一步筛选。这里，将无人车站点信息集合中的每一个无人车站点信息，与所得到的至少一个待播放内容进行比较。从至少一个待播放内容中选取所关联的站点信息与该 无人车站点信息相匹配的待播放内容，存入待播放内容集合。
步骤203，将待播放内容子集合发送给无人车，以使无人车对待播放内容子集合中的待播放内容进行播放。
在本实施例中，执行主体可以通过有线连接方式或者无线连接方式将待播放内容子集合发送给无人车。
继续参见图3，图3是根据本实施例的用于推送信息的方法的应用场景的一个示意图。在图3所示的应用场景300中，首先，服务器301确定通信连接的无人车302的无人车行车路线信息。然后，服务器301根据无人车行车路线信息，从预先存储的待播放内容集合{A，B，C，D，E，F，G}中，筛选出与无人车行车路线信息相匹配的待播放内容A，C，D，G，存入待播放内容子集合，得到待播放内容子集合为{A，C，D，G}。最后，将待播放内容子集合{A，C，D，G}发送给无人车302，以使无人车302对待播放内容子集合{A，C，D，G}中的待播放内容进行播放。
本申请的上述实施例提供的用于推送信息的方法，可以确定通信连接的无人车的车辆信息。其中，车辆信息包括无人车行车路线信息。然后，根据车辆信息，从预先存储的待播放内容集合中，筛选出与车辆信息相匹配的待播放内容，存入待播放内容子集合。最后，将待播放内容子集合发送给无人车，以使无人车对待播放内容子集合中的待播放内容进行播放。本实施例的方法，采用无人车的无人车行车路线信息，从预先存储的待播放内容集合中筛选待播放内容，可以实现将具有针对性的待播放内容发送给无人车。
进一步参考图4，作为对上述各图所示方法的实现，本申请提供了一种用于推送信息的装置的一个实施例，该装置实施例与图2所示的方法实施例相对应，该装置具体可以应用于各种服务器中。
如图4所示，本实施例的用于推送信息的装置400包括：信息确定单元401，被配置成确定通信连接的无人车的车辆信息，车辆信息包括无人车行车路线信息。信息存储单元402，被配置成根据车辆信息，从预先存储的待播放内容集合中，筛选出与车辆信息相匹配的待播放内容，存入待播放内容子集合。信息发送单元403，被配置成将 待播放内容子集合发送给无人车，以使无人车对待播放内容子集合中的待播放内容进行播放。
在本实施例的一些可选的实现方式中，车辆信息还包括车辆类型信息，信息确定单元401可以进一步被配置成：首先，接收无人车的路线制定请求信息，路线制定请求信息包括无人车的无人车身份标识信息、起点信息和终点信息。然后，根据无人车身份标识信息确定无人车的无人车车辆类型信息，以及根据起点信息和终点信息确定无人车的无人车行车路线信息。
在本实施例的一些可选的实现方式中，无人车行车路线信息包括至少一个无人车站点对应的无人车站点信息集合，且待播放内容集合中的待播放内容关联有站点信息和车辆类型信息。
在本实施例的一些可选的实现方式中，信息存储单元402进一步被配置成：根据无人车车辆类型信息，从待播放内容集合中查找到与无人车车辆类型信息相匹配的至少一条待播放内容；对于无人车站点信息集合中的无人车站点信息，从至少一条待播放内容中选取与该无人车站点信息相匹配的待播放内容，将所选取的待播放内容存入待播放内容子集合。
本申请的上述实施例提供的装置，信息确定单元401确定通信连接的无人车的车辆信息，车辆信息包括无人车行车路线信息。之后，信息存储单元402根据车辆信息，从预先存储的待播放内容集合中，筛选出与车辆信息相匹配的待播放内容，存入待播放内容子集合。最后，信息发送单元403将待播放内容子集合发送给无人车，以使无人车对待播放内容子集合中的待播放内容进行播放。本实施例的装置，采用无人车的无人车行车路线信息，从预先存储的待播放内容集合中筛选待播放内容，可以实现将具有针对性的待播放内容发送给无人车。
进一步参考图5，作为对上述各图所示方法的配套实现，本申请示出了用于控制内容的呈现的方法的一个实施例的流程500。该用于控制内容的呈现的方法的流程500，包括以下步骤：
步骤501，获取无人车的当前位置坐标。
在本实施例中，用于控制内容的呈现的方法的执行主体可以为用 于控制无人车的控制器。执行主体可以通过全球定位系统(Global Positioning System，GPS)获取无人车的当前位置坐标，也可以通过其它方式获取无人车的当前位置坐标。
步骤502，响应于确定当前位置坐标与预设的至少一个位置坐标之间的距离值中存在小于距离阈值的距离值，从待播放内容子集合中选取待播放内容以通过呈现设备进行内容呈现。
其中，待播放内容子集合接收自通信连接的服务器且是服务器通过执行如下步骤发送的：确定无人车的车辆信息；根据车辆信息，从预先存储的待播放内容集合中，筛选出与车辆信息相匹配的待播放内容，存入待播放内容子集合；发送待播放内容子集合。
在本实施例中，执行主体可以通过有线连接方式或者无线连接方式接收服务器基于无人车行车路线信息和无人车车辆类型信息发送的待播放内容子集合。之后，执行主体可以将所接收到待播放内容子集合存储在无人车中，以使得无人车每一次在无人车行车路线信息所指示的道路行驶过程中，均可以播放待播放内容子集合中的待播放内容。
在本实施例中，执行主体可以通过如下方式确定当前位置坐标与预设的至少一个位置坐标之间的距离值中存在小于距离阈值的距离值：对于预设的至少一个位置坐标，从至少一个位置坐标中选取位置坐标，执行如下确定步骤：计算所选取的位置坐标与当前位置坐标之间的距离值，若距离值小于距离阈值，则确定当前位置坐标与预设的至少一个位置坐标之间的距离值中存在小于距离阈值的距离值。否则，从至少一个位置坐标中选取未被选取的位置坐标，继续执行上述确定步骤。这里，可以采用距离计算公式计算所选取的位置坐标与当前位置坐标之间的距离值。其中，上述预先设定的位置坐标可以是技术人员预先设定的位置坐标。作为示例，预先设定的至少一个位置坐标可以为某个景区大门处的位置坐标，也可以是某个公交站点的位置坐标，还可以是无人车站点的位置坐标。
在本实施例的一些可选的实现方式中，执行主体还可以通过如下方式确定当前位置坐标与预设的至少一个位置坐标之间的距离值中存在小于距离阈值的距离值：首先，确定当前位置坐标与预先设定的至 少一个位置坐标之间的距离的最小值。这里，执行主体可以采用距离计算公式计算当前位置坐标与至少一个位置坐标中的每个位置坐标间的距离。这样，可以得到至少一个距离中的最小值。然后，若最小值小于设定距离阈值，则可以确定当前位置坐标与预设的至少一个位置坐标之间的距离值中存在小于距离阈值的距离值。
在本实施例中，执行主体在确定当前位置坐标与预设的至少一个位置坐标之间的距离值中存在小于距离阈值的距离值之后，可以从待播放内容子集合中选取待播放内容以通过呈现设备进行内容呈现。这里，执行主体可以随机选取设定数量个待播放内容呈现给用户。执行主体也可以选取被选取次数较少的设定数量个待播放内容呈现给用户。
在本实施例的一些可选的实现方式中，执行主体还可以通过如下步骤从待播放内容子集合中选取待播放内容：
第一步，确定小于距离阈值的距离值对应的位置坐标。这里，执行主体可以直接得到小于距离阈值的距离值对应的位置坐标。
第二步，确定无人车行车路线信息中的、与所确定的位置坐标相匹配的无人车站点对应的无人车站点信息。在本实施例中，无人车行车路线信息包括至少一个无人车站点对应的无人车站点信息集合。其中，无人车站点信息集合中的无人车站点信息包括但不限于站点名称和站点位置坐标。无人车站点可以是技术人员预先设定的位置点。在本实施例中，执行主体可以计算所确定的位置坐标与各个无人车站点信息中的站点位置坐标之间的距离，可以得到至少一个距离值。然后，将具有最小距离值的站点位置坐标所对应的无人车站点，确定为与对应于最小值的位置坐标相匹配的无人车站点。之后，可以得到该无人车站点的无人车站点信息。
第三步，根据所确定的无人车站点信息，从待播放内容子集合中选取与无人车站点信息相匹配的待播放内容。在本实施例中，待播放内容集合中的待播放内容关联有站点信息。这里，将所确定的无人车站点信息，与待播放内容子集合中的每个待播放内容进行比较，若该待播放内容所关联的站点信息与所确定的无人车站点信息相匹配，则 选取该待播放内容。其中，待播放内容所关联的站点信息与所确定的无人车站点信息相匹配，可以是指二者相同，也可以是指二者相应。作为示例，若待播放内容所关联的站点信息是字符“S”，所确定的无人车站点信息是字符组“station”，字符“S”与字符组“station”所表征的站点为同一站点，则可以认为待播放内容所关联的站点信息与所确定的无人车站点信息相应。此时，待播放内容所关联的站点信息与所确定的无人车站点信息相匹配。
在本实施例的一些可选的实现方式中，用于控制内容的呈现的方法还可以包括如下步骤：
第一步，接收用户通过通信连接的输入设备输入的手动播放请求信息。其中，输入设备可以是键盘，也可是鼠标，还可以是其它可以进行信息输入的设备。手动播放请求信息可以是用于请求手动播放内容的各种信息。作为实例，手动播放请求信息可以是字符组“manu-play”。
第二步，对于待播放内容子集合中的待播放内容，确定该待播放内容的内容类别信息，响应于内容类别信息集合中不存在所确定的内容类别信息，将所确定的内容类别信息存入内容类别信息集合。
在本实施例中，待播放内容子集合中的待播放内容关联有内容类别信息。内容类别信息可以是用于表征待播放内容的类别的各种信息。作为示例，内容类别信息可以是字母“M”，用于表征待播放内容的类别为音乐。另外，待播放内容的类别可以为技术人员预先设定的各种类别。作为示例，待播放内容的类别可以包括但不限于体育、音乐、教育、旅游、美食。在本实施例中，执行主体可以直接采用待播放内容得到该待播放内容所关联的内容类别信息。之后，执行主体判断所得到的内容类别信息是否存在于内容类别信息集合中，若不存在，则将所得到的内容类别信息存入内容类别信息集合。反之，若存在，则不存入内容类别信息集合。其中，内容类别信息集合在缺省情况下为空集。需要指出的是，获取待播放内容子集合中各待播放内容的内容类别信息，并存入内容类别信息集合，是为了让用户可以通过选择内容类别来确定播放的内容，可以提高无人车的视频播放效率。
第三步，将内容类别信息集合通过呈现设备呈现给用户。
在本实施例中，执行主体可以将所得到的内容类别信息集合通过呈现设备呈现给用户。其中，呈现设备可以是音箱，也可以是显示屏，还可以是其他电子设备。
第四步，接收用户通过通信连接的输入设备输入的选择请求信息，选择请求信息包括用户所选择的内容类别信息，根据选择请求信息，从待播放内容子集合中筛选出与所选择的内容类别信息相匹配的待播放内容。
在本实施例中，执行主体在接收到通信连接的输入设备输入的选择请求信息时，可以采用所选择的内容类别信息，从待播放内容子集合中筛选出与所选择的内容类别信息相匹配的待播放内容。
第四步，将待播放内容通过呈现设备呈现给用户。
在本实施例中，执行主体将用户所选择的内容类别对应的待播放内容呈现给用户，可以提高无人车的视频播放效率。
继续参见图6，作为对上述图5所示方法的实现，本申请提供了用于控制内容的呈现的装置的一个实施例。该装置实施例与图5所示的方法实施例相对应，该装置具体可以应用于各种控制器中。
如图6所示，本实施例的用于控制内容的呈现的装置600可以包括：位置获取单元601，被配置成获取无人车的当前位置坐标；内容选择单元602，被配置成响应于确定当前位置坐标与预设的至少一个位置坐标之间的距离值中存在小于距离阈值的距离值，从待播放内容子集合中选取待播放内容以通过呈现设备进行内容呈现，其中，待播放内容子集合接收自通信连接的服务器且是服务器通过执行如下步骤发送的：确定无人车的车辆信息；根据车辆信息，从预先存储的待播放内容集合中，筛选出与车辆信息相匹配的待播放内容，存入待播放内容子集合；发送待播放内容子集合。
