    所述停车诱导系统，还用于将每一个所述停车场的标识以及每一个停车场的空闲停车位的停车位类型下发给所述车载通讯终端，以使所述车载通讯终端所在车辆的驾驶员根据自身停车技能以及所述每一个停车场的空闲停车位的停车位类型选择相应的目标停车场；
    所述停车诱导系统，还用于检测所述车载通讯终端上报的所述目标停车场，并生成所述目标停车场的位置与所述当前车辆位置之间的诱导路径，并将所述诱导路径发送给所述车载通讯终端进行停车诱导。
  7. 根据权利要求6所述的停车诱导系统，其特征在于：
    所述停车诱导系统，还用于在将所述诱导路径发送给所述车载通讯终端进行停车诱导之后，判断所述停车诱导系统的当前工作负荷是否超过所述停车诱导系统指定的工作负荷；如果所述停车诱导系统的当前工作负荷未超过所述停车诱导系统指定的工作负荷，通过天气信息查询端口向所述天气信息查询端口对应的天气服务系统发起包括所述目标停车场的位置的天气信息查询请求；接收所述天气服务系统通过所述天气信息查询端口返回的所述目标停车场的位置对应的预设时长的天气信息；将所述目标停车场的位置对应的预设时长的天气信息下发给所述车载通讯终端。
  8. 根据权利要求6或7所述的停车诱导系统，其特征在于：
    所述车载通讯终端，还用于在向所述停车诱导系统上报停车请求之前响应所述车载通讯终端所在车辆的驾驶员输入的停车位搜索指令，获取所述车载通讯终端配置的至少两个不同的定位接口；以及，将定位请求发送至所述至少两个不同的定位接口，以触发每个定位接口分别将接收到的定位请求发送给各自对应的定位服务器；以及，获取至少一个定位接口对应的定位服务器发送的位置信息，并获取从第一时刻到第二时刻的响应时间，第一时刻为每个定位接口发送定位请求的时刻，第二时刻为每个定位接口接收到位置信息的时刻；以及，将与每个定位接口对应的响应时间与响应阈值进行比较，并从响应时间未超过响应阈值的定位接口所接收的位置信息中提取定位精度最高的位置信息作为当前车辆位置。
  9. 根据权利要求8所述的停车诱导系统，其特征在于：
    所述车载通讯终端，还用于在响应所述车载通讯终端所在车辆的驾驶员输入的停车位搜索指令，获取所述车载通讯终端配置的至少两个不同的定位接口之前，识别所述车载通讯终端所在车辆的驾驶员的情绪是否稳定，如果情绪不稳定，提示所述驾驶员停车；如果情绪稳定，所述车载通讯终端每隔指定时间采集一帧所述驾驶员的人脸图像，并从所述人脸图像中确定出人眼定位矩形，并计算所述人眼定位矩形的面积，根据阈值判断所述驾驶员的眼睛的睁闭程度，以及根据所述驾驶员的眼睛的睁闭程度评价出人眼疲劳程度值，以及基于所述人眼疲劳程度值判断所述驾驶员的眼睛是否疲劳，如果疲劳，提示所述驾驶员停车。
  10. 根据权利要求6～9任一项所述的停车诱导系统，其特征在于，所述车载通讯终端向停车诱导系统上报停车请求的方式具体为：
    所述车载通讯终端，用于扫描周围环境中是否预先设置有接入节点，如果预先设置有所述接入节点，检测所述接入节点是否被配置有开放接入时段，如果所述接入节点被配置有所述开放接入时段，识别所述车载通讯终端的当前系统时间是否位于所述接入节点被配置的所述开放接入时段内；如果所述车载通讯终端的当前系统时间位于所述接入节点被配置的所述开放接入时段内，检测所述接入节点的当前接入的终端数量是否超过所述接入节点指定的最大终端接入数量；如果所述接入节点的当前接入的终端数量未超过所述接入节点指定的最大终端接入数量，建立与所述接入节点之间的无线连接，并且向所述接入节点上报停车请求，由所述接入节点将所述停车请求进行加密后发送给所述停车诱导系统。
