具体实施方式
下面将结合附图，对本公开的实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例仅仅是本公开的一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
图1是根据本公开的一实施例提供的一种用于车辆的智能油料提示装置的结构示意图。如图1所示，该装置包括：油量传感器1、GPS模块2、中央处理单元3及提示模块4。
所述油量传感器1用于获得车辆的油耗信息；所述GPS模块2用于获得所述车辆的位置信息；所述中央处理单元3用于根据所述车辆的位置信息及所述油耗信息，获得所述车辆的可达范围信息；所述提示模块4用于提示所述车辆的可达范围信息。
本实施例能够使得用户充分了解剩余油量能够行驶的距离，实现了关于油量的有效提醒，例如使用户能够进一步判断车辆的剩余油量是否足够支持车辆到达目的地，从而对是否需要进行加油进行进一步有效判断。
车辆的油耗信息可以包括：剩余油料的总量及单位油耗。剩余油量的总量可由车辆中的传感器定时获取，并进一步通过例如蓝牙、ZIGBEE或者有线传输至中央处理单元。单位油耗，即，单位距离消耗的油料，可通过h＝Δg/Δd计算，其中，Δd为车辆在预设时间段内的行驶距离、Δg为车辆在预设时间段内的油耗。
中央处理单元可以根据剩余油料的总量、单位油耗、以及该车辆的位置信息，获得所述车辆的可达范围信息。例如，首先根据剩余油料的总量及单位油耗获得车辆能够行驶的距离；然后，根据车辆的位置信息并且基于地图获得该车辆周围的道路信息；最后，根据车辆能够行驶的距离及该车辆周围的道路信息，获得车辆的可达范围信息。
提示模块可包括显示模块。附加地，提示模块也可包括语音提示模块。如图2所示，可以例如在地图上将车辆的可达范围信息用如图2中的方框标注出来。附加地，也可以用语音进行实时播放提醒。如此，实现了对车辆剩余油量能够行驶的距离及范围进行有效提醒。
图3示出了本公开的另一实施例提供的一种用于车辆的智能油料提示装置的结构示意图。该装置包括：油量传感器1、GPS模块2、中央处理单元3、提示模块4及加油站信息模块5。
油量传感器1、GPS模块2、中央处理单元3及提示模块4的功能与参照图1描述的实施例相似，在此不再赘述。
加油站信息模块5被配置用于获取加油站的位置信息。
相应地，中央处理单元3进一步被配置用于根据所述加油站的位置信息及所述车辆的可达范围信息，判断所述车辆是否能够到达距离所述车辆最近的加油站。
具体来说，所述根据所述加油站的位置信息及所述车辆的可达范围信息，判断车辆的是否能够达到距离车辆最近的加油站可包括：
根据加油站的位置信息获得距离所述车辆最近的加油站；获取所述车辆及该最近的加油站之间的距离；判断该车辆的可达范围信息所指示的能够行驶的距离与所述车辆及该最近的加油站之间的距离之间的差值是否小于等于第一预设阈值；或者，
根据加油站的位置信息获得距离所述车辆最近的加油站；获取所述车辆到达该最近的加油站所需的油量；判断该车辆的剩余油料的总量与上述所需的油量之间的差值是否小于等于第二预设阈值。
提示模块4还被配置用于当所述车辆无法到达距离所述车辆最近的加油站时，对用户进行提示。具体地，该车辆能够行驶的距离与所述车辆及该最近的加油站之间的距离之间的差值小于等于第一预设阈值时，对用户进行提示；或者，该车辆的剩余油料的总量与该车辆行驶到最近的加油站所需的油量之间的差值小于等于第二预设阈值时， 对用户进行提示。从而，能够对用户进行及时的提醒，避免在加油站稀疏的地段，出现油量耗尽的情况。
提示模块4对用户进行提示的方式可以包括蜂鸣、振动或灯光闪烁等。
本实施例中，中央处理单元3可以根据加油站的位置信息及所述车辆的可达范围信息，确定所述车辆的可达范围内是否存在加油站，以及实时检测车辆的剩余油量是否能够达到最近的加油站。若不能到达，对用户进行及时且有效的提示，使用户能够采取紧急预防措施，例如轻踩油门来节油、空挡滑行、或从别车借油等非常规措施。
图4示出了本公开的另一实施例提供的一种用于车辆的智能油料提示装置的结构示意图。如图4所示，该装置包括：油量传感器1、GPS模块2、中央处理单元3、提示模块4、加油站信息模块5及无线通信模块6。
油量传感器1、GPS模块2、中央处理单元3、提示模块4及加油站信息模块5的功能与上述实施例中描述的相似，在此不再赘述。
无线通信模块6被配置用于实时获取加油站的位置信息，并将所述加油站的位置信息发送至所述加油站信息模块5。如此，可通过无线通信模块更新加油站信息模块5中存储的加油站的位置信息，使得加油站信息模块5中的加油站的位置信息始终保持最新及准确。
所述无线通信模块6还可被配置用于获取道路相关信息，并将所述道路相关信息发送至所述中央处理单元3。
相应地，所述中央处理单元3可用于根据所述车辆的位置信息、油耗信息及所述道路相关信息，获得所述车辆的可达范围信息；根据所述加油站的位置信息及所述车辆的可达范围信息，判断车辆是否能够到达距离所述车辆最近的加油站。
本实施例中，考虑到道路相关信息包括诸如路面拥堵信息、限速信息等，所述中央处理单元3中计算车辆的可达范围，具体包括：
获取所述车辆在预设时间段内的行驶距离Δd、所述预设时间段内的油耗信息Δg，及当前路段的道路相关系数j，根据公式(1)计算得到当前单位油耗：
h＝Δg/Δd/j  (1)
根据所述单位油耗、所述车辆的位置信息及所述道路相关系数，采用公式(2)获得所述车辆的可达范围信息：
Figure PCTCN2016104540-appb-000003
其中，h是当前单位油耗，g是剩余油料的总量，di是各段道路上车辆能够行驶的长度，其中根据道路相关系数将道路分为i段，1≤i≤n且为整数，n≥1且为整数，ji是各段道路的道路相关系数。di可以用于表示所述车辆的可达范围信息。
可选地，所述道路相关系数为拥堵系数。
当所述道路相关系数为拥堵系数时，所述根据道路相关系数将道路分为i段具体包括：获取基于地图显示的路面拥堵信息，该地图上用不同颜色来表示不同的路面拥堵情况，如红色表示严重拥堵，黄色表示行驶缓慢，绿色表示行驶畅通等，然后可根据与路面拥堵信息对应的显示的颜色将道路分为i段。例如，如图5所示，车辆至加油站A1之间的道路根据颜色分为两段d1和d2，即d1对应的颜色和d2对应的颜色不同。同样，车辆至加油站A2之间的道路根据颜色分为三段d3、d4和d5，车辆至加油站A3之间的道路根据颜色也分为三段d6、d7和d8。
根据上述公式(2)对车辆周边道路进行广度搜索。车辆的可达范围信息指的是：对于从该车辆的位置开始可行驶的多条道路，车辆的剩余油料的总量在各道路上所能够行驶的距离。
如图5所示，提示模块4可对车辆的可达范围、车辆位置信息及加油站位置信息进行提示。图5中方框标示出了车辆的可达范围，且在不同的方向中，根据拥堵系数可将道路分为多段，例如：往北的方向道路分为d1和d2两段，向西的方向道路分为d3、d4和d5三段，向东的方向道路也分为d6、d7和d8三段。明显可以看出，往北或向东该车辆均可达到A1、A2两个加油站，而车辆如果向西行驶则无法达到A3加油站。根据图示的信息，用户可方便地判断是否需要加油，以及去哪个加油站加油。
可选地，所述道路相关系数还可为限速系数。
当所述道路相关系数为限速系数时，所述根据道路相关系数将道路分为i段具体包括：获取基于地图的限速信息，即对于不同的路段有不 同的限速值，如不同路段的限速值分别为20km/h、30km/h、40km/h及60km/h等等，然后根据不同的限速值可将道路分为i段。例如，如图5所示，车辆至加油站A1之间的道路根据限速值分为两段d1和d2，即d1对应的限速和d2对应的限速值不同。同样，车辆至加油站A2之间的道路根据限速值分为三段d3、d4和d5，车辆至加油站A3之间的道路根据限速值也分为三段d6、d7和d8。
本实施例提供的智能油料提示装置中，通过无线通信模块6获得道路相关信息，如路面拥堵信息、限速信息等，中央处理单元3对车辆的可达范围进行计算时将道路相关信息考虑进去，从而使得该装置对车辆油耗情况进行更为准确地判断。

S703：根据所述加油站的位置信息及所述车辆的可达范围信息，判断所述车辆是否能够到达距离所述车辆最近的加油站。

获取所述车辆到达最近的加油站所需的油量；判断该车辆的剩余油料的总量与所需的油量之间的差值是否小于等于第二预设阈值。
S704：当所述车辆无法到达距离所述车辆最近的加油站时，对用户进行提示。
需要说明的是，当所述车辆能够到达距离所述车辆最近的加油站时，则转至步骤S701继续对油量进行检测及判断，对油量进行实时检测及判断。
当所述车辆无法到达距离所述车辆最近的加油站时，对用户进行提示。具体地，该车辆的可达范围信息与所述车辆及该最近的加油站之间的距离之间的差值小于等于第一预设阈值时，对用户进行提示；或者，该车辆的剩余油料的总量与所需的油量之间的差值小于等于第二预设阈值时，对用户进行提示。这样，能够对用户进行及时的提醒，避免在加油站稀疏的地段，出现油量耗尽的情况。
本实施例中，进一步获得加油站的位置信息。然后，根据加油站的位置信息及所述车辆的可达范围信息，确定所述车辆的可达范围内是否存在加油站，以及实时检测车辆的剩余油量是否能够达到最近的加油站。若不能到达，对用户进行及时且有效的提示，使用户及时给车辆加油。
图8示出了本公开的另一实施例提供的一种用于车辆的智能油料提示方法的流程示意图，如图8所示，该方法包括如下步骤：
S801：获取车辆的油耗信息、位置信息、道路相关信息及加油站的位置信息；
本步骤与图7所示实施例的步骤S701相比，还需获取道路相关信息。例如，可将通过网络获取的当前各路段的拥堵系数作为道路相关信息，或者将通过网络获取的各路段的限速信息作为道路相关信息。
S802：根据所述车辆的位置信息、所述油耗信息及所述道路相关信息，获得所述车辆的可达范围信息；
S803：根据所述加油站的位置信息及所述车辆的可达范围信息，判 断所述车辆是否能够到达距离所述车辆最近的加油站；
S804：当所述车辆无法到达距离所述车辆最近的加油站时，对用户进行提示。
所述根据所述车辆的位置信息、所述油耗信息及所述道路相关信息，获得所述车辆的可达范围信息，具体地可通过如下方法实现：
获取所述车辆在预设时间段内的行驶距离Δd、所述预设时间段内的油耗信息Δg，及当前路段的道路相关系数j，根据公式一计算得到当前单位油耗：
h＝Δg/Δd/j公式一；
根据所述单位油耗、所述车辆的位置信息及所述道路相关系数，采用公式二获得所述车辆的可达范围信息：

若基于地图显示的所述路面拥堵信息中路段显示为深红色，设置该路段的拥堵系数为第四拥堵系数；
其中，所述第一拥堵系数<第二拥堵系数<第三拥堵系数<第四拥堵系数。
由此可见，路面拥堵程度越严重，拥堵系数设置的越高。
举例来说，当地图路段显示为绿色，拥堵系数j值取1；当地图路段显示为黄色，拥堵系数j值取1.1；当地图路段显示为红色，拥堵系数j值取1.2；当地图路段显示为深红色，拥堵系数j值取1.3。

若所述限速信息中的限速值大于等于第四预设阈值且小于第三预设阈值，则设置该路段的限速系数为第三限速系数；
若所述限速信息中的限速值小于第四预设阈值，则设置该路段的限速系数为第四限速系数；
其中，第一限速系数<第二限速系数<第三限速系数<第四限速系数。可理解的是，本实施例只是对限速系数的设置进行举例说明，当限速值包括四种以上的情况时，上述方法仍然适用，在此不再赘述。
举例来说，第一预设阈值取值为90km/h,第二预设阈值取值为70km/h，第三预设阈值取值为50km/h，第四预设阈值取值为30km/h。若当前路段限速值为80km/h，则限速系数j值取1；若当前路段限速值为60km/h，则限速系数j值取1.1；若当前路段限速值为30km/h，则限速系数值取1.4；若当前路段限速值为20km/h，则限速系数j值取1.5。
对于方法实施例而言，由于其与装置实施例基本相似，所以描述的比较简单，相关之处参见装置实施例的部分说明即可。
