在一种现有技术中，现有用户在导航过程中，终端设备在导航中可处于灭屏状态，通过语音对用户进行提示，此方案虽然可以节省屏幕的功耗，但是语音提示的触发判断程序仍然运行在应用处理器上，应用处理器上进行事件的判断还会有一定数量的电流消耗，例如100mA(毫安)以上的电流消耗，导致终端设备上的导航应用功耗高。

附图说明
为了更清楚地说明本发明实施例的技术方案，下面将对本发明实施例中所需要使用的附图作简单地介绍，显而易见地，下面所描述的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1是根据本发明实施例的导航装置示意图。
图2是根据本发明实施例的应用场景示例的示意图。
图3是根据本发明实施例的导航方法示意图。
图4是根据本发明实施例的导航方法另一示意图。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚地描述，显然，所描述的实施例是本发明的一部分实施例，而不是全部实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都应属于本发明保护的范围。
终端设备，也可称之为用户设备、移动用户设备等，可以经无线接入网与一个或多个核心网进行通信，用户设备可以是终端设备，如移动电话(或称为“蜂窝”电话)和具有终端设备的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。
图1示出了根据本发明实施例的导航装置100示意图，该装置100包括主处理器110、协处理器120、定位器130和第一存储器140。
主处理器110，用于生成导航数据，将该导航数据存储到该第一存储器140，并且在存储该导航数据之后进入休眠状态；
定位器130，用于确定导航装置100的当前位置；
协处理器120，用于从获取第一存储器140中存储的该导航数据，并且根据该导航数据以及该定位器130确定的该导航装置100的当前位置，进行导航，进行导航包括触发该主处理器110进行导航数据的更新、触发语音播报和确定该导航数据中需要显示的数据中的至少一项；其中，主处理器110的功率大于协处理器120的功率，也即主处理器110的功耗大于协处理器120的功耗。
可选地，主处理器110、协处理器120、定位器130和第一存储器140可以通过总线连接，或者通过其它内部连接线路或器件连接。本实施例及后续实施例中涉及的“连接”应理解为是一种电性连接，并非直接的相连，这种连接可通过第三方器件间接实现相连。
具体而言，主处理器110可以生成导航数据，导航数据通常是主处理器110规划的用户的行驶路径，一般选择最优地或者最快的路径，也可以规划多条路径供用户选择，主处理器110将生成的该导航数据存储到该第一存储器140中，随后进入休眠状态，主处理器110在休眠状态时的功耗较低。该休眠状态也叫睡眠状态、待机或低功耗状态，其功耗低于主处理器110正常工作时的功耗。协处理器120可以从第一存储器140中获取该导航数据，并且根据该导航数据和定位器130确定的导航装置100的当前位置，进行导航， 由于该协处理器120的功耗小于该主处理器110的功耗，则该协处理器120进行导航而主处理器110休眠可以降低该导航装置100的功耗，从而提高该导航装置100的续航能力。
主处理器110一般功耗较高，处理能力较强，例如ARM(Advanced RISC Machine，进阶精简指令集机器)公司的cortex A系列的芯片，cortex A系列运行驱动软件以便执行处理操作，驱动软件可以是存储在存储器中，如之前所述第一存储器140，或者更常见的，驱动软件通常被存放于不同于第一存储器140的其他存储器中。驱动软件所存于的存储器可以是非掉电易失性存储器。驱动软件可以包括应用软件，应用软件通过应用程序接口与主处理器110上运行的操作系统对接，操作系统可以是安卓、Windows或iOS等，本发明实施例不限于此。协处理器120可以是微控制器(Microprogrammed Control Unit，简称“MCU”)或数字信号处理器(Digital Signal Processing，简称“DSP”)等，主处理器110可以是CPU(Central Processing Uint，中央处理单元)或DSP等，本发明实施例不限于此。
应理解，定位器130可采用基于卫星定位、WiFi(Wireless Fidelity，无线保真)定位、基站定位等的定位技术，利用这些定位技术确定包括该导航装置100的当前位置，本发明实施例不限于此。卫星定位包括但不限于GPS(Global Positioning System，全球定位系统)定位和北斗定位技术等。
作为一个可选实施例，该协处理器120具体用于根据该导航数据以及该定位器130确定的该导航装置100的当前位置，确定需要唤醒该主处理器110。
这样，主处理器110产生导航数据后，主处理器110进入休眠状态，协处理器120根据导航数据和导航装置100的当前位置判断是否唤醒主处理器110，主处理器110的功耗大于协处理器120的功耗，在不需要主处理器110介入时，主处理器110进入休眠状态，在需要主处理器110介入时协处理器120唤醒主处理器110，主处理器110生成新的导航数据后，再次进入休眠状态，从而可以降低导航装置100的功耗，提高该导航装置100的续航能力。
作为一个可选实施例，该导航数据包括：多个第一标志点的位置数据，该多个第一标志点在当前规划路径中间隔分布；协处理器120具体用于：当该导航装置100的当前位置与该多个第一标志点中的每个第一标志点之间的距离大于第一阈值时或确定该导航装置100的当前位置与距离该当前位置最 近的第一标志点之间的距离大于该第一阈值时，确定需要唤醒该主处理器110进行导航数据的更新。
应理解，多个第一标志点可以是主处理器110在生成导航数据的过程中确定的，如在用户输入出发地和目的地时，主处理器110根据用户的输入，确定用户的行驶路径，即规划路径。在主处理器110规划的行驶路径上可以每间隔一定的距离定义标志点，如每间隔50m作为标志点，或者间隔不等的距离定义标志点，或者在规划路径上将有标识意义的点定义为标志点，本发明实施例不限于此，这里的第一阈值可以理解为多个第一标志点中每个第一标志点对应的围栏半径，每个围栏半径可以相同或者不同，若第i个第一标志点对应的围栏半径是a，第i+1个第一标志点对应的围栏半径是b，则第i个第一标志点与第i+1个第一标志点的距离小于a+b，也即第i个第一标志点为中心，a为半径形成的圆与第i+1个第一标志点为中心，b为半径形成的圆相交或相切。
作为一个可选实施例，该协处理器120具体还用于在确定需要唤醒该主处理器110进行导航数据的更新之后，向该主处理器110发送第一触发消息，该第一触发消息用于请求该主处理器110重新规划行驶路径；该主处理器110还用于：接收该协处理器120发送的该第一触发消息；根据该第一触发消息，从该休眠状态转换至工作状态并且生成更新后的导航数据。
具体而言，第一阈值是主处理器110在生成导航数据时就已经确定的，协处理器120根据多个第一标志点的位置数据与导航装置100的当前位置之间的距离判断是否需要唤醒主处理器110，如协处理器120检测到导航装置100当前的位置与多个第一标志点的位置的距离小于或等于预先设定的第一阈值时，即导航装置100当前的位置在以多个第一标志点为圆心，第一阈值为半径的围栏范围内，协处理器120认为导航装置100没有偏离规划好的路径，不需要唤醒主处理器110；若协处理器120检测到导航装置100当前的位置与多个第一标志点的位置的距离大于预先设定的第一阈值时，即导航装置100当前位置超出了以多个第一标志点为圆心，第一阈值为半径的围栏范围，协处理器120认为导航装置100偏离了规划好的路径，确定需要唤醒主处理器110进行导航数据的更新，协处理器120向主处理器110发送第一触发消息，来唤醒主处理器110对导航装置100的路径进行重新规划。协处理器120也可以根据导航装置100运动的速度或加速度以及第一阈值(围栏半 径)来判定导航装置100的位置，确定导航装置100是否落入以多个第一标志点为中心，第一阈值为半径的围栏内，本发明实施例不限于此。
应理解，主处理器110在生成导航数据的过程中多个第一标志点设定相同或不同的阈值，如可以设定相同的围栏半径如可以都是20m，对应的第一阈值可以设定为20m，也可以针对不同的标志点设定不同的围栏半径，也可以是M个第一标志点对应N个围栏半径，对应有N个第一阈值，M和N都为正整数，M大于等于N，本发明实施例不限于此。
作为一个可选实施例，该导航数据包括：用于触发语音播报的第二标志点的位置数据，该第二标志点包括当前规划路径中的路径转折点、服务区和标志性建筑中的至少一项，如可以是转弯、掉头、出/入主路、上桥、餐厅和加油站等。
作为一个可选实施例，该协处理器120具体还用于：当确定该导航装置100的当前位置与该第二标志点之间的距离小于第二阈值时，确定需要唤醒该主处理器110进行语音播报的触发。
作为一个可选实施例，如图1所示，导航装置100还可以包括该播放器170，该协处理器120还用于在确定需要唤醒该主处理器110进行语音播报的触发之后，向该主处理器110发送第二触发消息，该第二触发消息用于指示该主处理器110触发语音播报，该第二触发消息可以携带该第二标志点的信息；该主处理器110还用于：接收该协处理器120发送的该第二触发消息；根据该第二触发消息，向播放器170发送用于执行语音播报的语音播报信息，应理解，该播放器170可以是终端设备包括的，播放器170也可以是独立的语音播放设备，本发明实施例不限于此。
具体而言，第二标志点在主处理器110进行路径规划的过程中确定，第二标志点可以是一个或多个，协处理器120根据第二标志点的位置数据与导航装置100的当前位置之间的距离判断是否需要触发语音播报，如协处理器120检测到导航装置100当前的位置与第二标志点的位置的距离小于或等于第二阈值时，即导航装置100当前的位置在以该标志点为圆心，第二阈值为半径的围栏范围内，协处理器120认为导航装置100即将到达该标志点，需要进行语音播报，协处理器120可以生成语音播报信息，向播放器170发送语音播报信息，播放器170根据该语音信息进行播报，协处理器120生成该语音播报信息可以是协处理器120从第一存储器140中获取该第二标志点相 关的语音播报信息，本发明实施例不限于此；若协处理器120检测到导航装置100当前的位置与某个标志点的位置的距离大于第二阈值时，即导航装置100当前的位置在以第二标志点为圆心，第二阈值为半径的围栏范围外，协处理器120认为导航装置100离该标志点较远，还不需要进行语音播报，如主处理器110进入休眠状态下的电流消耗大约是6mA，而协处理器120进行导航实现和语音播报的电流消耗大约是200mA，而主处理器110进行导航实现和语音播报的电流消耗大约是600mA，因此通过协处理器120进行导航实现和语音播报，主处理器110休眠的方式，可以节约大约394mA的电流消耗。
作为一个可选实施例，该协处理器120具体还用于：当确定该导航装置100的当前位置与该第二标志点之间的距离小于第三阈值时，向播放器170发送用于执行语音播报的语音播报信息，以便于该播放器170根据该语音播报信息进行语音播报。
具体地，协处理器120检测到导航装置100当前的位置与第二标志点的位置的距离小于或等于第三阈值时，即导航装置100当前的位置在以第二标志点为圆心，第三阈值为半径的围栏范围内，协处理器120认为导航装置100即将到达第二标志点，需要进行语音播报，协处理器120可以向主处理器110发送第二触发消息，第二触发消息用于唤醒主处理器110进行语音播报，主处理器110根据第二触发消息生成语音播报信息，向播放器170发送语音播报信息，播放器170根据该语音信息进行播报，主处理器110生成该语音播报信息可以是协处理器120从第一存储器140中获取第二标志点相关的语音播报信息，第二触发消息也可以携带该语音播报信息，本发明实施例不限于此；若协处理器120检测到导航装置100当前的位置与某个标志点的位置的距离大于第三阈值时，即导航装置100当前的位置在以该标志点为圆心，第三阈值为半径的围栏范围外，协处理器120认为导航装置100离该标志点较远，还不需要进行语音播报，第三阈值可以与上述的第一阈值或第二阈值相同或者不同，第一阈值与第二阈值相同或者不同，本发明实施例不限于此。
应理解，多个第一标志点可以包括第二标志点，也可以不包括第二标志点，在本发明实施例中，多个第一标志点用于判断是否需要主处理器110重新进行路径规划，第二标志点用于判断是否需要语音播报，这里标志点的划分是针对导航事件划分的。
应理解，该导航装置100可以是独立的一个导航装置100，也可以是终端设备包括的导航装置100，如确定导航装置100的当前位置可以认为导航装置100与终端设备独立存在，若终端设备包括该导航装置100，则定位器130可以确定终端设备的当前位置，本发明实施例不限于此。
作为一个优选实施例，用户主动对终端设备进行启动时，终端设备处于亮屏状态；主处理器110接收协处理器120发送的第一触发消息，并根据第一触发消息对终端设备的路径进行重新规划时，终端设备处于亮屏状态。终端设备亮屏时，此时主处理器110可以接收协处理器120发送的第二触发消息，并根据第二触发消息进行语音播报，既然终端设备亮屏，主处理器110进行路径规划，已经需要较大的功耗，此时需要进行语音播报时，主处理器110可以进行语音播报，这样，可以在主处理器110规划路径的同时进行语音播报，由于主处理器110规划路径时终端设备处于亮屏状态，亮屏状态下终端设备的功耗比较大，此时若也需要进行语音播报，则协处理器120可以唤醒主处理器110触发语音播报，主处理器110同时进行路径规划和触发语音播报的功耗小于主处理器110独立进行一次路径规划和独立进行一次语音播报的功耗，这样在一定程度上也可以降低功耗。
作为一个可选实施例，如图1所示，该导航装置100还可以包括：第二存储器150，也可以包括直接内存访问(Direct Memory Access，简称“DMA”)设备；DMA用于：从该第一存储器140中获取该导航数据，将该导航数据存储于该第二存储器150中；该协处理器120还用于：从该第二存储器150中获取该导航数据。
作为一个可选实施例，第一存储器140中的导航数据也可以通过总线传送到第二存储器150中，第一存储器140可以是双倍速率(Double Data Rate，简称“DDR”)同步动态随机存储器，第二存储器150可以是静态随机存取存储器(Static RAM，简称“SRAM”)，主处理器110可以将导航数据存储到第一存储器140中的，在主处理器110休眠之前将第一存储器140中的数据通过总线传输到第二存储器150中，或者DMA获取第一存储器140中的导航数据，并存储器第二存储器150中，通常情况下，第一存储器140的功耗可以比第二存储器150的功耗大，协处理器120在进行判断或者语音播报从第二存储150器中获取导航数据，这样可以进一步地降低整个导航过程中的功耗。
作为一个可选实施例，如图1所示，该导航装置100还包括：显示器160，该协处理器120具体还用于：确定导航数据中需要显示的数据，并且向该显示器160发送该需要显示的数据；显示器160用于接收该协处理器120发送的该需要显示的数据，根据该需要显示的数据生成并显示导航图像。
可选地，装置100还可以包括：驱动器，用于驱动显示器显示导航图像。
可选地，导航数据还可以包括：标志点的地理属性、经纬度、坐标位置等信息，也可以包括地图图层信息、出发地和目的地信息等，也可以包括主处理器110或协处理器120执行算法或运行程序过程中生成的一些中间数据，本发明实施例不限于此。
例如，地图图层信息可以是：用于显示器160显示所使用的整个地图相关信息，在经过主处理器110处理前是数据信息，主处理器110处理后变为图层数据信息，以便于显示器160进行显示。标志点可以是：导航路径上的一系列坐标点；标志点可以是一栋房子、一个商铺、一个邮筒、一个公交站、一个限速拍照点等，每个标志点也可以包含该地点名称、类别、经度、纬度。导航数据还可以包括：用户的出发地和目的地信息等，在本发明实施例中的导航数据可以是所有与导航相关的数据，本发明实施例不限于此。
应理解，在本发明的所有实施例中提到的距离，可以是二维平面坐标中的距离；也可以是三维坐标中的空间距离，本发明实施例不限于此。
也应理解，主处理器110的休眠状态也可以称为睡眠或低功耗状态，其不会完全下电，但其运行电压或时钟频率中的至少一个会低于该主处理器110正常工作执行程序时的值，从而使主处理器110能够节省功耗。
因此，主处理器110产生导航数据后，主处理器110进入休眠状态，协处理器120根据导航数据和导航装置100的当前位置判断是否唤醒主处理器110，主处理器110的功耗大于协处理器120的功耗，在需要主处理器110介入时协处理器120唤醒主处理器110，在不需要主处理器110介入时，主处理器110进入休眠状态，从而可以降低导航装置100的功耗，提高导航装置100的续航能力。
图2示出了本发明实施例的应用场景示例的示意图。终端设备包括导航装置100、蜂窝通信处理器和天线，其中，导航装置100用于导航，蜂窝通信处理器用于通过天线与无线网络设备通信，该无线网络设备可以是基站或基站控制器，用来为终端设备提供蜂窝无线通信服务，该终端设备可以是手 机、平板电脑等，本发明实施例不限于此。
因此，终端设备中的导航装置100根据导航数据和终端设备的当前位置利用围栏判断是否需要重新规划路径或语音播报，主处理器110产生导航数据后，主处理器110处于休眠状态，主处理器110的功耗大于协处理器120的功耗，在需要主处理器110介入时协处理器120唤醒主处理器110，在不需要主处理器110介入时，主处理器110处于休眠状态，从而可以降低导航装置100的功耗，进而增加终端设备的待电时间，减少频繁地用充电线对终端设备进行充电的过程中带来的不便。
图3示出了根据本发明实施例的导航方法200示意图，该导航方法200包括：
S210，主处理器110生成导航数据，将该导航数据存储到第一存储器140，并且在存储该导航数据之后进入休眠状态；
S220，定位器130确定该导航装置100的当前位置；

作为一个例子，由主处理器110进行路径规划，生成一系列标志点，如图4所示：在标志点中，定义E2为第二标志点，如：转弯、掉头等，在E2位置附近需要执行语音播报，E1为第二标志点E2临近的路径上的点，图4中的A、B、C、D、…….、F为第一标志点，其中A为出发地，F为目的地，并设定相应的地理围栏半径(例如20m)，形成相应的前后关系，为A→B→C→D→…….→E1→E2→F。地理围栏半径可以是一个第二标志点的预设距离阈值，通常是以第二标志点为圆心，第一阈值(例如20m)为半径形成一个区域，该区域用于判断使用该导航装置100的用户是否处于该第二标志点从而触发后续操作，例如，若用户坐标与该第二标志点坐标的几何距离小于等于该围栏半径，即在区域内，则认为用户处于原始的规划路径上，若用户坐标与该第二标志点坐标的几何距离大于该围栏半径，即用户当前的位置不在该区域内，则认为用户偏离了规划的行驶路径，需要重新进行行驶路径的规划，每个第二标志点所对应的阈值可以是相同或不同。地理围栏半径也可以是一个第二标志点的预设距离阈值，通常是以第二标志点为圆心，第二阈值(例如500m)为半径形成一个区域，该区域用于判断用户是否处于该第二标志点从而触发语音播报，例如，若用户坐标与该第二标志点坐标的几何距离大于该围栏半径，即认为用户还未到达该第二标志点，不需要进行语音播报，若用户坐标与该第二标志点坐标的几何距离小于或等于围栏半径，即用户即将要到达该第二标志点，需要进行语音播报，每个第二标志点所对应的阈值可以相同或不同。
