本申请实施例提供了一种无人车调度方法，参照图2，图2为本申请无人车调度方法第一实施例的流程示意图。
本实施例中，所述无人车调度方法包括以下步骤：
步骤S10：获取无人车位置信息以及所述无人车周围预设范围内的物体与所述无人车之间的距离信息；
需要说明的是，本实施例方法的执行主体可以是上述无人车调度设备，该设备可以是具有数据获取以及分析运算功能的、能够进行全城车辆调度的计算服务设备(服务器)或系统，也可以是其它具有类似功能的设备，本实施例对此不作限制。
可理解的是，车载终端是车辆监控管理系统的前端设备，也可以叫做车辆调度监控终端，它集成定位，通信、汽车行驶记录仪等多项功能；具有强大的业务调度功能和数据处理能力。在本实施例中，无人车可通过内置的车载终端对车辆进行全球定位系统(Global Positioning System，GPS)定位，获取无人车的位置信息以及无人车周围预设范围(如，3米、5米、7米等)内的物体(如，行人、花坛、非机动车辆和/或机动车辆等)的距离信息。在获取到自身的位置信息以及上述距离信息后，车载终端可将获取到的信息上传至无人车调度设备。
在具体实现中，所述无人车调度设备接收无人车车载终端发送的所述无人车位置信息以及所述距离信息。
步骤S20：接收所述预设范围内若干辆人工驾驶车辆上传的行驶信息，并根据所述行驶信息对所述人工驾驶车辆的进行行驶路径预测，获得若干对应的预测路径；
可以理解的是，实际情况中，无人车在道路上行驶时周围预设范围内的物体中可能包括若干辆人工驾驶的车辆。为了能够保证无人车调度的安全性，这些人工驾驶车辆可响应于无人车调度设备发送的信息获取请求，通过内置的车载终端将自身的行驶信息上传至所述无人车调度设备。
所述行驶信息可包括：车辆速度信息、车辆位置信息、历史行驶路径信息和/或目的地信息等。相应地，所述无人车调度设备在接收到不同人工驾驶车辆发送的行驶信息后，可根据该行驶信息对人工驾驶车辆接下来一段时间的行驶路径进行大致预测，以获取不同人工驾驶车辆对应的行驶路径，即所述预测路径。
步骤S30：基于所述预测路径，根据所述无人车位置信息以及所述距离信息对所述无人车的行驶路径进行规划，获得目标行驶路径，并将所述目标行驶路径发送至所述无人车，实现对所述无人车的调度。
在本步骤中，所述无人车调度设备在获取到不同人工驾驶车辆对应的预测路径后，可基于所述预测路径以及无人车与周围物体的距离信息来对在保证无人车不与周围物体发生碰撞的前提下，结合无人车当前所处的位置信息来对无人车的行驶路径进行一个大致规划，获得无人车接下来的行驶路径，即所述目标行驶路径。在得出无人车对应的行驶路径后，所述无人车调度设备将该行驶路径发送至无人车，以使无人车的按照所述目标行驶路径行驶，保证无人车行驶的安全性。
本实施例无人车调度设备通过获取无人车位置信息以及无人车周围预设范围内的物体与无人车之间的距离信息；然后接收预设范围内若干辆人工驾驶车辆上传的行驶信息，并根据行驶信息对人工驾驶车辆的进行行驶路径预测，获得若干对应的预测路径；然后基于预测路径，根据无人车位置信息以及距离信息对无人车的行驶路径进行规划，获得目标行驶路径，并将目标行驶路径发送至无人车，实现对无人车的调度。由于是以无人车周围一定范围内人工驾驶车辆的预测路径以及无人车与周围物体之间的距离信息作为路径规划依据来确定无人车的目标行驶路径，从而能够保证无人车行驶过程中的安全性， 减少了交通事故的发生率。
参考图3，图3为本申请无人车调度方法第二实施例的流程示意图。
基于上述第一实施例，在本实施例中，所述步骤S20包括：
步骤S201：接收所述预设范围内若干辆人工驾驶车辆上传的行驶信息；
可以理解的是，无人车在道路上行驶时，周围可能存在大量的人工驾驶车辆，为了避免无人车调度设备获取过多的人工驾驶车辆上传的驾驶信息，从而导致无人车调度设备长时间处于高运算量状态，影响其使用寿命。本实施例中可以无人车为中心以预设距离为半径，设定一个行驶信息的接收范围(即所述预设范围)，以便所述无人车调度设备只接收该预设范围内的人工驾驶车辆上传的行驶信息。其中，所述预设距离可根据实际经验值设定，具体数值本实施例不做限制。
步骤S202：获取当前网络延时，根据所述当前网络延时确定所述行驶信息对应的传播时长；
应理解的是，由于网络环境的差异，信息数据的传递会存在延时，因此，为了保证人工驾驶车辆行驶路径预测的准确性，本实施例在对人工驾驶车辆的行驶路径进行预测时，考虑数据传递的网络延时。具体的，所述无人车调度设备根据所述行驶信息离开人工驾驶车辆的时刻(即离开时刻)以及接收到所述行驶信息的时刻(即接收时刻)确定出所述当前网络延时，即传播时长＝当前网络延时＝接收时刻-发送时刻。
在获取到当前网络延时后，所述无人车调度设备即可确定出行驶信息对应的传播时长。
步骤S203：根据所述传播时长和所述行驶信息对所述人工驾驶车辆的进行行驶路径预测，获得若干对应的预测路径。
在具体实现中，无人车调度设备确定出行驶信息的传播时长后，便可根据行驶信息中包含的车辆速度信息和车辆位置信息来对人工驾驶车辆的行驶路径进行预测，从而获得预测路径。
进一步地，为了保证人工驾驶车辆行驶路径预测的有效性，本实 施例会对人工驾驶车辆在一段时间内的行驶距离进行预测。具体的，所述无人车调度设备可先提取行驶信息中的车辆位置信息以及车辆行驶速度，然后根据所述车辆行驶速度和所述传播时长，确定所述人工驾驶车辆在预设时段内的行驶距离；根据所述车辆位置信息和所述行驶距离对所述人工驾驶车辆的进行行驶路径预测，获得预测路径。考虑信息传递的延时性，本实施例中所述行驶距离的具体计算方式可以是根据公式S＝V×(2T
1+T
2)获得，其中，S为行驶距离，V为车辆行驶速度，T
1为传播时长，T
2为预设时段。所述预设时段为预先设定的预测时长，例如1分钟，2分钟等。
本实施例无人车调度设备通过接收预设范围内若干辆人工驾驶车辆上传的行驶信息，获取当前网络延时，根据所述当前网络延时确定所述行驶信息对应的传播时长；根据传播时长和行驶信息中包含的车辆行驶速度，确定所述人工驾驶车辆在预设时段内的行驶距离；根据行驶距离和行驶信息中包含的车辆位置信息和车辆行驶方向对所述人工驾驶车辆的进行行驶路径预测，获得预测路径，从而使得获得的预测路径更加准确有效，进一步提升了无人车调度的安全性。
参考图4，图4为本申请无人车调度方法第三实施例的流程示意图。
基于上述各实施例，在本实施例中，所述步骤S10之后，所述方法还包括：
步骤S101：在检测到存在与所述无人车的距离小于预警距离的物体时，向所述无人车发送制动指令，以控制所述无人车降低车速。
可以理解的是，所述无人车调度设备可根据无人车上传的距离信息获取无人车周围的物体(行人、花坛、非机动车辆和/或机动车辆等)与无人车之间的当前距离。
为了保证无人车行驶的安全性，避免无人车与周围物体的距离过近发生碰撞事故。在本实施例中，可预先设定一个安全距离，即所述预警距离，来防止碰撞事故的发生。所述预警距离的具体数值可以根据实际情况设定，例如：1米、1.5米等，本实施例对此不做限制。
在具体实现中，所述无人车调度设备在检测到所述当前距离小于 预警距离时，表明无人车此时与周围物体的距离过近，此时无人车调度设备会向所述无人车发送制动指令，以使所述无人车响应于所述制动指令降低车速或进行紧急刹车，防止碰撞。
本实施例无人车调度设备通过从距离信息中获取无人车周围预设范围内的物体与无人车之间的当前距离；在检测到当前距离小于预警距离时，向无人车发送制动指令，以使无人车响应于制动指令降低车速，有效地让无人车保持与周围物体的距离，保证行车安全。
基于上述各实施例，提出本申请一种无人车调度方法第四实施例。
在本实施例中，所述步骤S30可具体包括以下步骤：
根据接收到的若干辆行驶信息，确定当前时刻所述无人车所在道路上的车辆平均速度；
可理解的是，所述无人车调度设备可根据人工驾驶车辆上传的行驶信息来大致确定当前道路上的车辆的平均行驶速度。当然，所述无人车调度设备也可以根据人工驾驶车辆或无人车所在的位置信息，从交通管制系统来获取当前时刻无人车所在道路上的车辆平均速度，本实施例对此不作限制。
获取所述无人车的当前车速，检测所述当前车速是否高于所述车辆平均速度；
在获取到当前道路上车辆的平均速度后，无人车调度设备可获取无人车的当前车速，并将所述当前车速与车辆平均速度进行比较，检测无人车是否存在速度过快的情况。
在检测到所述当前车速低于所述车辆平均速度时，根据所述预测路径、所述无人车位置信息以及所述距离信息对所述无人车的行驶路径进行规划，获得目标行驶路径。
在具体实现中，当所述无人车调度设备检测到当前车速低于所述车辆平均速度时，即可根据不同人工驾驶车辆各自对应的预测路径，无人车的位置信息以及无人车与周围物体的距离信息对所述无人车的行驶路径进行规划，从而获得安全有效的目标行驶路径。
在检测到所述当前车速高于所述车辆平均速度时，向所述无人车 发送制动指令，并根据所述预测路径、所述无人车位置信息以及所述距离信息对所述无人车的行驶路径进行规划，获得目标行驶路径。
在具体实现中，当所述无人车调度设备检测到当前车速高于所述车辆平均速度时，表明无人车的当前车速可能偏快，出于安全考虑，所述无人车调度设备可向无人车发送制动指令，以使无人车将车速降低到所述车辆平均速度附近，然后再根据所述预测路径、所述无人车位置信息以及所述距离信息对所述无人车的行驶路径进行规划，获得目标行驶路径。
进一步地，为了避免无人车频繁进行制动操作，在对无人车的当前车速进行检测时，可设定一个制动因子来判断此时无人车是否需要进行制动操作，具体的，可令制动因子＝当前车速/车辆平均速度，当检测到所述制动因子大于预设阈值(例如5％、8％等)时，判定无人车当前需要进行制动；反之则不需要进行制动，保持当前车速即可。
本实施例无人车调度设备根据接收到的若干辆行驶信息，确定当前时刻无人车所在道路上的车辆平均速度；获取无人车的当前车速，检测当前车速是否高于车辆平均速度；在检测到当前车速低于车辆平均速度时，根据预测路径、无人车位置信息以及距离信息对无人车的行驶路径进行规划；在检测到当前车速高于车辆平均速度时，向无人车发送制动指令，然后再进行行驶路径规划，保证了无人车调度的安全性。
