图 5是依据本发明一较佳实施例的畅通路段上报方法 500的流程图。如图 5所示， 拥塞路段上报方法 500开始于步骤 502。
随后， 在下一步骤 504, 检测所在车辆行驶速度高于或等于第二预设速度 阈值的持续时长。
在具体实现过程中，可在检测到车辆行驶速度高于或等于第二预设速度阈 值时启动计时器。在计时器启动之后， 若检测到车辆行驶速度低于第二预设速 度阈值， 则重置计时器。 如此一来， 当车辆行驶速度持续高于或等于第二预设 速度阈值，便可通过计时器计算出这种状态的持续时间， 即车辆行驶速度高于 或等于第二预设速度阈值的持续时间。
随后， 在下一步骤 506, 判断车辆行驶速度高于或等于第二预设速度阈值 的持续时长是否超过第二预设时长阈值， 若是， 则转到步骤 508, 否则回到步 骤 104。
如上文所述，若在步骤 506判定车辆行驶速度高于或等于第二预设速度阈 值的持续时长超过第二预设时长阈值， 则转到步骤 508 , 确定当前所在路段。 随后， 方法 500转到步骤 510。
在具体实现过程中，车载导航设备可定期接收卫星导航信号，据此确定当 前所在路段。作为可选的， 车载导航设备还可基于收到的卫星导航信号确定所 在车辆的行驶方向。
在具体实现过程中，车载导航设备还可采用其他方式确定当前所在路段和 行马史方向。
随后， 在下一步骤 510, 发出畅通消息， 其中包含当前所在路段的名称。 作为可选的， 该畅通消息还可包含车载导航设备所在车辆的行驶方向。
在具体实现过程中，车载导航设备可将上述当前所在路段的名称和所在车 辆的行驶方向包含在短消息 （例如但不限于 SMS消息） 中发出。
在具体实现过程中， 车载导航设备可将该畅通消息发往交通监管服务器。 最后， 方法 500结束于步骤 512。
图 6是依据本发明一较佳实施例的车载导航设备 600的逻辑结构示意图。 如图 6, 车载导航设备 600包括检测模块 602、 判断模块 604、 定位模块 606 和移动通信模块 608。
检测模块 602 用于检测所在车辆的行驶速度高于或等于第二预设速度阈 值的持续时长。在具体实现过程中，检测模块 602可在检测到车辆行驶速度高 于或等于第二预设速度阈值时启动计时器。在计时器启动之后， 若检测到车辆 行驶速度低于第二预设速度阈值， 则重置计时器。 如此一来， 当车辆行驶速度 持续高于或等于第二预设速度阈值，便可通过计时器计算出这种状态的持续时 间， 即车辆行驶速度高于或等于第二预设速度阈值的持续时间。
判断模块 604与检测模块 602通信连接，用于在判定所在车辆的行驶速度 高于或等于第二预设速度阈值的持续时长超过第二预设时长阈值时发出定位 通知。
定位模块 606用于在收到定位通知时， 确定当前所在路段。
在具体实现过程中，定位模块 606可定期接收卫星导航信号，据此确定当 前所在路段。作为可选的， 定位模块 606还可基于收到的卫星导航信号确定所 在车辆的行驶方向。
在具体实现过程中，车载导航设备还可采用其他方式确定当前所在路段和 行马史方向。
移动通信模块 608用于发出包含当前所在路段名称的畅通消息。作为可选 的， 畅通消息中还可包含所述行驶方向。
在具体实现过程中移动通信模块 608可将所述畅通消息包含在短消息（例 如但不限于 SMS消息） 中发出。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发 明的精神和原则之内所作的任何修改、等同替换和改进等， 均应包含在本发明 的保护范围之内。
