具体实施方式
随着信息技术的不断发展，汽车的智能化程度越来越高，也有越来越多的车厂将车载T-BOX作为汽车的标准配置。车载T-BOX可用于实现远程启动车辆、打开车内空调、调整车内座椅至合适位置以及与其他通信设备进行通信等功能。
其中，车载T-BOX各种功能的实现离不开电源为其提供的供电。图1为本申请实施例提供的车载T-BOX与车辆连接的示意图。如图1所示，通常情况下，车载T-BOX是由车辆的车内供电系统101，通过车载T-BOX的T-BOX与车内连接器103将电源提供给车载T-BOX的电源管理单元104，以便由电源管理单元104向车载T-BOX的无线通信与处理单元105以及车载T-BOX的T-BOX用电单元106提供供电，从而使得车载T-BOX实现其功能。例如，车载T-BOX通过无线通信与处理单元105与其他通信设备进行通信。
当车辆的车内供电系统101出现异常无法提供供电时，车载T-BOX可以利用其内置电池107独立进行工作。具体的，当车内供电系统101出现异常无法向车载T-BOX提供供电时，车载T-BOX的内置电池107代替车辆的车内供电系统101，将电源提供给车载T-BOX的电源管理单元104，以使得车载T-BOX实现其功能。另外，部分类型的内置电池107还支持可充电，当内置电池107的电量使用完后，还可以利用车辆的车内供电系统101给其充电。
但是，对于车辆来说，车内用电单元102主要是由车内供电系统101提供供电的。在车内供电系统101出现异常无法向车内用电单元102提供供电时，没有技术能够实现给车内用电单元102的供电。
本申请实施例提供一种供电方法，在车内供电系统出现异常无法提供供电时，利用车载T-BOX的内置电池向车内用电单元提供供电，以满足用户的紧急需求。
图2为本申请实施例提供的一种供电方法的流程示意图。该供电方法应用于车载T-BOX，该车载T-BOX包括供电单元，所述供电单元用于提供电源。如图2所示，该供电方法可以包括：
S201、车载T-BOX接收第一指示信号，该第一指示信号用于指示供电单元为车辆的车内用电单元提供供电。
其中，车辆中配置有所述车载T-BOX。所述供电单元可以为电池。通常情况下，车辆的车内用电单元是由车内用电系统提供供电的，但是，当车辆的车内供电系统发生异常时，车内供电系统便无法为车内用电单元提供供电。在本申请实施例中，为了当车辆的车内供电系统发生异常无法为车内用电单元提供供电时，可以由车载T-BOX向车内用电单元的供电。
在本申请实施例中，车辆的车内供电系统发生异常可以是车辆的自检系统检测到车内供电系统出现故障，例如，车辆的自检系统检测到车辆的蓄电池电量低于一定的阈值，或者蓄电池的电量高于一定的阈值等。车内供电系统故障的具体实现可以根据实际应用场景来确定，本申请实施例在此不做具体限制。
在一些实施例中，在车辆的车内供电系统出现异常无法提供供电时，车辆可以向车载T-BOX发送第一指示信号，以指示车载T-BOX的供电单元为车辆的车内用电单元提供供电。示例性的，车辆可以采用无线通信技术向车载T-BOX发送第一指示信号，也可以通过物理通路向车载T-BOX发送第一指示信号。
在又一些实施例中，在车辆的车内供电系统出现异常无法提供供电的情况下，可以由辅助设备向车载T-BOX发送用于指示车载T-BOX的供电单元为车辆的车内用电单元提供供电的第一指示信号。所述辅助设备可以是除车辆外任何能够与车载T-BOX通信的设备，例如，手机、平板电脑等移动终端。示例性的，辅助设备可以采用无线通信技术向车载T-BOX发送第一指示信号，也可以通过物理通路向车载T-BOX发送第一指示信号。
需要说明的是，所述无线通信技术可以是蓝牙(Bluetooth，BT)技术，也可以是无线保真(Wireless Fidelity，WiFi)技术，还可以是第2代移动通信技术(The second Generation Telecommunication，2G)、第3代移动通信技术(The third Generation Telecommunication，3G)、第4代移动通信技术(The fourth Generation  Telecommunication，4G)、第5代移动通信技术(The fifth Generation Telecommunication，5G)或者下一代通信技术。当然还可以是其他无线通信技术，在此不做具体限定。
另外，由于车载T-BOX的供电单元能够提供的电源有限，因此，在车辆的车内供电系统出现异常无法提供供电的情况下，可以在用户有紧急需求时，由车辆或辅助设备向车载T-BOX发送第一指示信号，以指示车载T-BOX的供电单元为车辆的车内用电单元提供供电，以满足用户的紧急需求。
例如，在车辆的车内供电系统出现异常的情况下，当用户需要给车辆的发动机进行电源点火时，用户可以通过触发车辆中的对应按钮，以使得车辆向车载T-BOX发送第一指示信号，以指示车载T-BOX的供电单元向车辆发动机的点火系统提供供电。
又例如，在车辆的车内供电系统出现异常的情况下，当用户需要打开车门时，用户可以通过触发辅助设备中的对应按钮，以触发辅助设备向车载T-BOX发送第一指示信号，以指示车载T-BOX的供电单元向车辆的电子开车门系统提供供电。
S202、车载T-BOX根据第一指示信号，控制供电单元通过对外供电电路向车内用电单元提供供电。
其中，在车载T-BOX接收到第一指示信号之后，车载T-BOX便可以控制自身的供电单元通过对外供电电路向车辆的车内用电单元提供供电。在本申请实施例中，所述对外供电电路为供电单元和车内用电单元之间的供电通路。其与车内供电系统和车载T-BOX的车载用电单元之间的供电通路不同。
示例性的，假设车辆与车载T-BOX之间采用无线通信技术进行通信，且采用的无线通信技术为蓝牙技术。如图3和图4所示，在车辆的车内供电系统301出现异常无法向车内用电单元提供供电的情况下，可以通过用户的触发，以使得车辆的蓝牙模块308采用蓝牙协议向车载T-BOX的蓝牙模块305发送第一指示信号，以指示车载T-BOX的供电单元307向车辆的车内用电单元302提供供电。在车载T-BOX的蓝牙模块305接收到第一指示信号之后，车载T-BOX的蓝牙模块305可以通过信号线路将该第一指示信号发送给车载T-BOX的电源管理单元304。电源管理单元304可以控制供电单元307通过对外供电电路向车内用电单元302提供供电。如，电源管理单元304通过如图3所示的经由T-BOX与车内连接器303和车内供电系统301的对外供电电路，将供电单元307的电源提供给车内用电单元302。或者，电源管理单元304通过如图4所示的经由T-BOX与车内连接器303的对外供电电路，将供电单元307的电源提供给车内用电单元302。
示例性的，假设车辆与车载T-BOX之间采用无线通信技术进行通信，且采用的无线通信技术为5G技术。如图5所示，在车辆的车内供电系统501出现异常无法向车内用电单元提供供电的情况下，可以通过用户的触发，以使得车辆的无线通信单元508采用5G技术，通过基站和车载T-BOX的T-BOX天线，向车载T-BOX的无线通信与处理单元505发送第一指示信号，以指示车载T-BOX的供电单元507向车辆的车内用电单元502提供供电。在车载T-BOX的无线通信与处理单元505接收到第一指示信号之后，车载T-BOX的无线通信与处理单元505可以通过信号线路将该第一指示信号发送给车载T-BOX的电源管理单元504。电源管理单元504可以控制供电单元507通过对外供电电路向车内用电单元502提供供电。如，电源管理单元504通过如图5所示 的经由T-BOX与车内连接器503和车内供电系统501的对外供电电路，将供电单元507的电源提供给车内用电单元502。或者，电源管理单元504也可以通过经由T-BOX与车内连接器503的对外供电电路，直接将供电单元507的电源提供给车内用电单元502。
示例性的，假设车辆与车载T-BOX之间采用物理通路进行通信，且车辆中设置有一按钮，用于触发车辆向车载T-BOX发送第一指示信号。如图6所示，在车辆的车内供电系统601出现异常无法向车内用电单元提供供电的情况下，用户可以触发对应按钮，此时车辆便可以通过与车载T-BOX的T-BOX与车内连接器603之间的物理通路，向车载T-BOX发送第一指示信号(该第一指示信号为硬件通信信号)，以指示车载T-BOX的供电单元607向车辆的车内用电单元602提供供电。例如，车辆通过与车载T-BOX的T-BOX与车内连接器603之间的物理通路，经T-BOX与车内连接器603和信号线路将第一指示信号发送至车载T-BOX的电源管理单元604，以便电源管理单元604控制供电单元607通过对外供电电路向车内用电单元602提供供电。如，电源管理单元604通过如图6所示的经由T-BOX与车内连接器603的对外供电电路，直接将供电单元607的电源提供给车内用电单元602。或者，电源管理单元604也可以通过经由T-BOX与车内连接器603和车内供电系统601的对外供电电路，将供电单元607的电源提供给车内用电单元602。
示例性的，在车辆的车内供电系统出现异常无法提供供电的情况下，假设由辅助设备采用无线通信技术向车载T-BOX发送第一指示信号，且采用的无线通信技术为4G技术，并以辅助设备是手机为例。如图7所示，在车辆的车内供电系统701出现异常无法向车内用电单元提供供电的情况下，手机可以采用4G技术，通过基站和车载T-BOX的T-BOX天线，向车载T-BOX的无线通信与处理单元705发送第一指示信号，以指示车载T-BOX的供电单元707向车辆的车内用电单元702提供供电。在车载T-BOX的无线通信与处理单元705接收到第一指示信号之后，可以将该第一指示信号通过信号线路发送给车载T-BOX的电源管理单元704。电源管理单元704可以控制供电单元707通过对外供电电路向车内用电单元702提供供电。如，电源管理单元704通过如图7所示的经由T-BOX与车内连接器703和车内供电系统701的对外供电电路，将供电单元707的电源提供给车内用电单元702。或者，电源管理单元704也可以通过经由T-BOX与车内连接器703的对外供电电路，直接将供电单元707的电源提供给车内用电单元702。
示例性的，在车辆的车内供电系统出现异常无法提供供电的情况下，假设是由辅助设备通过物理通路向车载T-BOX发送第一指示信号的，且以辅助设备是手机为例。如图8所示，在车辆的车内供电系统801出现异常无法向车内用电单元提供供电的情况下，手机可以通过与车载T-BOX的T-BOX与手机连接器808(如，T-BOX与手机连接器808可以为通用串行总线(Universal Serial Bus，USB)接口)之间的物理通路，向车载T-BOX发送第一指示信号(该第一指示信号为硬件通信信号)，以指示车载T-BOX的供电单元807向车辆的车内用电单元802提供供电。例如，手机通过与车载T-BOX的T-BOX与手机连接器808之间的物理通路，经T-BOX与手机连接器808和信号线路将第一指示信号发送至车载T-BOX的电源管理单元804，以便电源管理单元 804控制供电单元807通过对外供电电路向车内用电单元802提供供电。如，电源管理单元804通过如图8所示的经由T-BOX与车内连接器803和车内供电系统801的对外供电电路，将供电单元807的电源提供给车内用电单元802。或者，电源管理单元804也可以通过经由T-BOX与车内连接器803的对外供电电路，直接将供电单元807的电源提供给车内用电单元802。
在上述由辅助设备向车载T-BOX发送第一指示信号的场景下，辅助设备发送第一指示信号可以是由用户触发的。例如，假设辅助设备为手机，手机安装的车载T-BOX的应用程序的显示界面如图9所示，当车辆的车内供电系统无法提供供电时，如图9所示，在车载T-BOX的应用程序的功能界面中，用户可以点击“对外供电”按钮图标901。手机在检测到用户对“对外供电”按钮图标901的点击操作之后，响应该点击操作向车载T-BOX发送第一指示信号，以指示车载T-BOX的供电单元向车辆的车内用电单元提供供电。
需要说明的是，在车辆的车内供电系统出现异常无法提供供电的情况下，车载T-BOX也可以控制供电单元向车载用电单元(如，车载T-BOX的无线通信与处理单元和/或车载T-BOX的T-BOX用电单元)提供供电，即车载T-BOX将使用内置的供电单元提供电源进行工作。例如，如图3所示，在车辆的车内供电系统301出现异常无法向车载用电单元提供供电时，车载T-BOX的供电单元307除了能够给车内用电单元302提供供电以外，还可以给车载T-BOX的蓝牙模块305和T-BOX用电单元306提供供电。示例性的，电源管理单元304可以将供电单元307的提供电源转换为三路电源，第一路电源输出给车载T-BOX的蓝牙模块305，第二路电源输出给T-BOX用电单元306，第三路电源通过对外供电电路输出给车内用电单元302。
另外，本申请实施例图4-图8所示的场景中，在车辆的车内供电系统出现异常无法提供供电的情况下，车载T-BOX也是可以使用内置的供电单元同时给车内用电单元和车载T-BOX自身的用电单元提供供电的，其具体描述与图3所示的场景中的对应描述类似，在此不再详细赘述。在车辆的车内供电系统能够正常提供供电的情况下，车载T-BOX由车辆的车内用电单元通过车内供电系统向车载T-BOX供电电路提供供电，其具体描述与图1所示的场景的描述类似，此处也不再赘述。
进一步的，为了节省车载T-BOX供电单元的电量，对外供电电路默认处于断开状态，在需要由车载T-BOX的供电单元向车辆的车内用电单元供电时，再导通所述对外供电电路。也就是说，如图10所示，在S202之前，该供电方法还可以包括：
S203、车载T-BOX控制对外供电电路导通。
其中，在车载T-BOX接收到第一指示信号之后，表明需要由车载T-BOX的供电单元向车辆的车内用电单元供电。车载T-BOX可以控制对外供电电路导通，具体的可以是车载T-BOX将对外供电电路的供电开关的开关信号由第一电平转换为第二电平，如，将对外供电电路的供电开关的开关信号由低电平转换为高电平，以控制所述对外供电电路导通。这样，车载T-BOX便可以控制供电单元通过对所述外供电电路向车内用电单元提供供电了。
例如，参见图3所示，所述对外供电电路为由车载T-BOX的电源管理单元304经车载T-BOX的T-BOX与车内连接器303到车辆的车内供电系统301的供电通路。 或者，参见图4所示，所述对外供电电路也可以为由车载T-BOX的电源管理单元304经车载T-BOX的T-BOX与车内连接器303到车辆的车内用电单元302的供电通路。又例如，参见图5所示，所述对外供电电路为由车载T-BOX的电源管理单元504经车载T-BOX的T-BOX与车内连接器503到车辆的车内供电系统501的供电通路。或者，参见图6所示，所述对外供电电路可以为由车载T-BOX的电源管理单元604经车载T-BOX的T-BOX与车内连接器603到车辆的车内用电单元602的供电通路。图7和图8中的对外供电电路与图5中的对外供电电路类似。
进一步的，在车载T-BOX通过对外供电电路向车内用电单元提供供电结束之后，如图11所示，该供电方法还可以包括：
S204、车载T-BOX接收第二指示信号，该第二指示信号用于指示供电单元停止为车内用电单元提供供电。
例如，当车辆的车内供电系统恢复正常，或者用户的紧急情况处理完成(如，车辆的发动机点火成功，车辆的车门成功打开等)的情况下，车辆或者辅助设备可以向车载T-BOX发送用于指示供电单元停止为车内用电单元提供供电的第二指示信号。
需要说明的是，在本申请实施例中，车辆或辅助设备向车载T-BOX发送第二指示信号的实现过程与本申请实施例中车辆或辅助设备向车载T-BOX发送第一指示信号的实现过程类似，对于车辆或辅助设备向车载T-BOX发送第二指示信号的具体描述，可以参考本申请实施例中对车辆或辅助设备向车载T-BOX发送第一指示信号的具体描述，本申请实施例在此不再详细赘述。
S205、车载T-BOX根据第二指示信号，控制供电单元停止为车内用电单元提供供电。
其中，在车载T-BOX接收到第二指示信号之后，表明需要车载T-BOX的供电单元停止向车辆的车内用电单元的供电。车载T-BOX可以根据第二指示信号，控制供电单元停止为车内用电单元提供供电。也就是说，车载T-BOX可以根据第二指示信号控制对外供电电路断开，具体的可以是将所述对外供电电路的供电开关的开关信号由第二电平转换为第一电平，如，将对外供电电路的供电开关的开关信号由高电平转换为低电平，以控制所述对外供电电路断开，节省车载T-BOX供电单元的电量。
在由辅助设备向车载T-BOX发送第二指示信号的场景下，辅助设备发送第二指示信号也可以是由用户触发的。例如，假设辅助设备为手机，当车辆的车内供电系统恢复正常，或者用户的紧急情况处理完成时，如图12所示，在车载T-BOX的应用程序的功能界面中，用户可以点击“对外供电”按钮图标1201。手机在检测到用户对“对外供电”按钮图标1201的点击操作之后，响应该点击操作向车载T-BOX发送第二指示信号，以指示车载T-BOX的供电单元向车辆的车内用电单元提供供电。
为了便于本领域技术人员理解，本申请在此对本申请实施例提供的供电方法进行举例说明。例如，车辆与车载T-BOX建立有蓝牙连接。参见图3所示，车辆的车内供电系统301出现异常无法向车辆的发动机的点火系统提供供电，用户需要给车辆的发动机进行电源点火时，用户可以触发车辆中对应的按钮，以使得车辆的蓝牙模块308采用蓝牙协议向车载T-BOX的蓝牙模块305发送第一指示信号，以指示车载T-BOX的供电单元307向车辆发动机的点火系统提供供电。车载T-BOX的蓝牙模块305接收 到第一指示信号后，通过信号线路将该第一指示信号发送给车载T-BOX的电源管理单元304。电源管理单元304控制对外供电电路导通，并控制供电单元307通过经由T-BOX与车内连接器303和车内供电系统301的对外供电电路，向车辆发动机的点火系统提供供电。进一步的，在车辆的发动机成功点火后，车辆的蓝牙模块308采用蓝牙协议向车载T-BOX的蓝牙模块305发送第二指示信号，以指示车载T-BOX的供电单元307停止向车辆发动机的点火系统提供供电。车载T-BOX的蓝牙模块305接收第二指示信号，并通过信号线路将该第二指示信号发送给车载T-BOX的电源管理单元304。电源管理单元304控制对外供电电路断开。在车内供电系统异常的情况下，用户也可以给车辆的发动机进行电源点火，满足紧急所需。
本申请实施例提供的供电方法，当车辆的车内供电系统出现异常无法提供供电时，车载T-BOX接收用于指示车载T-BOX的供电单元为车辆的车内用电单元提供供电的指示信号，车载T-BOX根据接收到的指示信号，控制供电单元通过对外供电电路向车内用电单元提供供电。解决了在车内供电系统出现异常时无法实现给车内用电单元提供供电的问题，以满足用户的紧急需求。并且，对外供电电路的状态默认为断开状态，在需要向车内用电单元提供供电时将其导通，节省了车载T-BOX供电单元的电量。
可以理解的是，上述车载T-BOX、车辆以及辅助设备为了实现上述功能，其包含了执行各个功能相应的硬件结构和/或软件模块。本领域技术人员应该很容易意识到，结合本文中所公开的实施例描述的各示例的单元及算法步骤，本申请实施例能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。专业技术人员可以对每个特定的应用来使用不同方法来实现所描述的功能，但是这种实现不应认为超出本申请实施例的范围。
本申请实施例可以根据上述方法示例对上述车载T-BOX进行功能模块的划分，例如，可以对应各个功能划分各个功能模块，也可以将两个或两个以上的功能集成在一个处理模块中。上述集成的模块既可以采用硬件的形式实现，也可以采用软件功能模块的形式实现。需要说明的是，本申请实施例中对模块的划分是示意性的，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式。

图15中示出的设备结构并不构成对车载T-BOX的限定，可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。
