Description

利用行车时间确定行车路线的方法与装置 技术领域
本发明涉及车载设备确定行车路线的技术， 尤其涉及一种利用行车时 间确定行车路线的方法与装置。 背景技术
调频（FM, Frequency Modulation )无线电台可以播放各种声音信息， 例如新闻、歌曲、广告等。此外，许多无线电台还具有广播 87.5M-107.9MHz 频带内的比特流的辅助通道， 也叫二级数字子信道， 形成所谓的无线数据 系统（ RDS, Radio Data System )广播。 RDS广播的主要特点是利用现有的 调频广播资源， 通过广播信号里插入数字码来实现， 只需少量的投资即可 建成广播发射端。 它与音频信号是分开的， 丝毫不会干扰收音， 也不会影 响收音机音质。 当收音机检测和解调这些数字码后， 便能提供相应的功能。 RDS广播可以使广播听众通过显示器看到无线电台的名称、 节目类型、 电 子邮件地址、 电话号码等信息。 一般说来， RDS以 1200 bps 至 2400bps的 速率进行信息广播。
如今， 电子地图技术得到了广泛的应用， 可以为用户在生活、 购物、 工作、 旅游、 出行等各方面的活动提供便捷的解决方案。 许多配备电子地 图的手持设备在用户输入目的点、 起始点后， 便可利用电子地图选择出一 条或者多条出行路线， 并展示给用户， 给用户带来了巨大的便利。 一般说 来， 电子地图给出的出行路线都是按照出行路线最短的原则进行选择的。
许多手持设备配备了电子地图功能与无线电接收功能， 图 1 为具有电 子地图及无线电接收功能的手持设备的组成结构示意图， 如图 1 所示， 手 持设备包括存储模块、 应用模块、 无线电接收模块及显示模块等， 其中， 电子地图存储至存储器中， 由应用模块调出并通过显示模块显示给用户； 无线电接收模块与应用模块电连接， 应用模块控制无线电接收模块进行接 收、 调台等， 无线电接收模块将接收到的音频信息、 RDS广播信息发送给 应用模块。
我国交通流数据检测系统可以监视整个交通网络的交通情况， 例如可 以检测每个路段上的车流量、 速度和密度等； 还可自动记录这些交通信息， 并将其按照固定格式发送给相关部门。 我国道路的实际情况比较复杂， 例 如拥有四条车道的道路， 有一条车道由于事故而堵塞， 但另外三条车道依 旧可以通行， 这样， 仅造成车流緩慢， 但依旧可以通行。 如果司机得到这 一路段的车流速度， 则必须自己计算出通过这一路段的行车时间。 如果行 车目的地较远的话， 则需要通过许多路段， 有的路段车流顺畅， 有的道路 车流緩慢， 甚至堵塞， 司机更难计算到达目的点的时间了。 如果电子地图 指出两条或者多条路线可以到达目的地， 司机还需计算出两条或者多条路 线的行车时间， 并进行比较， 这样就更加麻烦。 况且， 道路情况在实时变 化， 司机更不可能一边开车一边计算行车时间来获得实时的行车时间。
目前的车载设备中虽然支持电子地图业务， 也能向用户推荐行车路线， 但所推荐的行车路线仅是线路距离较近的路线， 用户实际行车及行车的用 时信息却没有， 实际上， 用时最少才是用户所追求的目的， 路线的长段的 参考意义是相当小的。 发明内容
有鉴于此， 本发明的主要目的在于提供一种利用行车时间确定行车路 线的方法与装置， 能根据到达目的地的用时向用户推荐合适的路线。
为达到上述目的， 本发明的技术方案是这样实现的：

未有实时路况信息的路段， 以该路段预先设定的平均行车速度计算通 过该路段的用时， 或者， 以该路段的限速车速计算通过该路段的用时， 或 者， 以预先设定的用户车辆的平均行车速度计算通过该路段的用时或者， 以用户设定的行车速度计算通过该路段的用时；

本发明的基本思想是： 根据所接收到的实时路况信息确定用户行车路 线上各路段的行车速度， 根据该路段的长度确定出用户通过该路段的用时 , 将所确定出的各路段用时叠加即为用户通过相应行车路线的总用时， 在向 用户显示行车路线时将用时信息一并通知给用户， 这样， 用户即可根据行 车路线及用时信息选择出最佳的行车路线， 大大方便了用户。
为使本发明的目的、 技术方案和优点更加清楚明白， 以下举实施例并 参照附图， 对本发明进一步详细说明。
本发明利用行车时间确定行车路线的方法通过图 1 所示的手持设备来 实现， 即手持设备既支持电子地图业务又支持无线电接收功能， 即能接收 到 RDS广播的路段的路况实时信息， 路况实时信息由广播电台、 交通中心 或专门的路况实时信息发布中心广播。 以下详细说明本发明是如何实现行 车路线推荐的。
图 2为本发明利用行车时间确定行车路线的方法的流程图， 如图 2所 示， 本发明利用行车时间确定行车路线的方法包括以下步骤：
步骤 201 : 根据用户输入的目的地信息确定行车路线，根据实时路况信 息及当前车速确定所述行车路线中各路段的车速， 计算各路段的行车用时 并确定各行车路线的总用时。
首先， 用户需要确定出行的目的地， 电子地图业务根据用户输入的目 的地信息确定出可能的行车路线， 即推荐出可行的行车路线。 该行车路线 是根据用户当前位置信息至目的地之间的所有可能行车路线中的距离较近 的一条或几条。
确定出用户的行车路线后， 根据当前所接收到的实时路况信息， 确定 前述行车路线中是否包含所接收到的实时路况信息所对应的路段， 一般的， 实时路况信息中包括路段的标识信息、 所测量的路段的行车平均速度以及 测量行车平均速度的时间等信息。 根据实时路况信息中的路段标识信息， 即可确定前述的行车路线中是否包含该路段。 确定出行车路线中包含有实 时路况信息携带的路段时， 确定该路段的行车时间将主要依据实时路况信 息中的平均行车速度来确定行车时间。 而没有实时路况信息的路段， 将以 该路段为正常状态而进行行车时间的确定， 例如以该路段的平均行车速度 确定行驶的时间， 路段的平均行车速度需预先设定。 以下详细说明本发明 是如何确定行车路线的用时的。
具有实时路况信息的路段， 获取所述实时路况信息中包含的行车速度 (平均行车速度）， 并判断该平均行车速度是否小于或等于用户设定的许可 速度， 若小于或等于用户输入的许可速度， 则以所述实时路况信息中包含 的行车速度计算通过该路段的用时， 若大于用户输入的许可速度， 则以用 户输入的许可速度计算通过该路段的用时。 例如， 用户是初驾者时， 驾驶 的最大车速可能只有 60公里 、时（ km/h ), 而实时路况信息返回的平均车 速是 70 km/h时， 将以用户设定的许可速度确定该路段的行车用时。 或者， 用户车上载有特殊人群如老人或儿童时， 也可以输入所允许的最大行车速 度， 若实时路况信息中的平均车速大于该允许车速时， 则以用户设定的许 可速度确定该路段的行车用时。 若小于用户设定的许可车速， 则直接以实 时路况中的平均车速计算该路段的行车用时。
未有实时路况信息的路段， 以该路段预先设定的平均行车速度计算通 过该路段的用时， 或者， 以该路段的限速车速计算通过该路段的用时， 或 者， 以用户车辆的平均行车速度计算通过该路段的用时。
对于未收到实时路况的路段， 则认为该路段是畅通的， 则以该路段行 车的平均车速（通过统计等方式而预先设定）计算通过该路段的用时， 例 如， 该路段畅通时的平均行车速度来计算通过该路段的用时， 如果该路段 是限速路段， 如限速 60 km/h, 则以该限速速度计算出通过该路段的用时， 而如果该路段是最低限速，如车速不能少于 70 km/h时， 则以该限速速度计 算出通过该路段的用时。 或者， 依据用户在畅通道路行车的平均行车速度 (预先设定值）或设定的行车车速来计算通过该路段的用时， 例如， 一般 在畅通的道路上， 用户的行车速度为 70 km/h, 那么则以该车速计算通过该 路段的用时； 如果用户设定了行车的默认速度， 如 60 km/h, 则以设定的默 认行车速度计算通过该路段的用时。
用户当前所处的路段， 以当前的车速计算通过该路段的用时。 对于用 户当前所在的路段， 则以当前的车速计算通过该路段的用时。
本领域技术人员应当理解， 行车路线所涉及的路段的长度通过电子地 图是很容易确定出距离的， 而确定出用户的行车速度后， 计算通过该路段 的行车用时是容易实现的。 由于本发明综合考虑了路段的实时路况信息， 这将能较准确地确定出行车路线的用时信息， 且具有相当的参考意义。
步骤 202: 将行车路线及用时信息通知用户。
将步骤 201 中确定出的各行车路线及其用时的信息向用户输出， 即通 知给用户， 由用户根据行车路线及其用时信息确定出具体的行车路线。 这 里， 可以根据行车路线的用时多少来向用户输出推荐路线， 如用时最少的 路线作为优选行车路线通知用户， 其中， 用时次少的几条行车路线同样也 推荐给用户， 作为备选行车路线。 需要说明的是， 手持设备处理能力支持 的情形下， 可将所有行车路线及其用时信息一并通知给用户， 由用户选择 出行车路线。
图 3为本发明利用行车时间确定行车路线的装置的组成结构示意图， 如图 3 所示， 本发明利用行车时间确定行车路线的装置包括第一确定单元 30、 接收单元 31、 第二确定单元 32、 计算单元 33、 第三确定单元 34和通 知单元 35 , 其中， 第一确定单元 30用于根据用户输入的目的地信息确定行 车路线； 接收单元 31用于接收实时路况信息； 所述实时路况信息中至少包 含有路段的车辆平均速度、 路段标识信息。 接收单元 31通过 RDS方式由 交通中心或无线广播台获知实时路况信息。 第二确定单元 32用于根据所述 实时路况信息及当前车速确定所述行车路线中各路段的车速； 计算单元 33 用于计算各路段的行车用时； 第三确定单元 34用于确定各行车路线的总用 时； 通知单元 35 用于将行车路线及用时信息通知用户。 第二确定单元 32 根据实时路况信息及当前车速确定所述行车路线中各路段的车速， 包括： 具有实时路况信息的路段， 获取所述实时路况信息中包含的行车速度， 若 小于或等于用户输入的许可速度， 则以所述实时路况信息中包含的行车速 度计算通过该路段的用时， 若大于用户输入的许可速度， 则以用户输入的 许可速度计算通过该路段的用时； 未有实时路况信息的路段， 以该路段预 先设定的平均行车速度计算通过该路段的用时； 或者， 以该路段的限速车 速计算通过该路段的用时； 或者， 以预先设定的用户车辆的平均行车速度 计算通过该路段的用时； 或者， 以用户设定的行车速度计算通过该路段的 用时； 用户当前所处的路段， 以当前的车速计算通过该路段的用时。
图 3所示装置可应用于各种手持设备或车载设备中。
本领域技术人员应当理解， 本发明图 3 所示的利用行车时间确定行车 路线的装置是为实现前述利用行车时间确定行车路线的方法而设计的，图 3 所示装置中的各处理单元的实现功能可参照前述利用行车时间确定行车路 线的方法中的相关描述而理解， 各单元的功能可通过运行于处理器上的程 序而实现， 也可通过相应的逻辑电路而实现。
以上所述， 仅为本发明的较佳实施例而已， 并非用于限定本发明的保 护范围。
