附图说明
附图是用来提供对本公开的进一步理解，并且构成说明书的一部分，与下面的具体实施方式一起用于解释本公开，但并不构成对本公开的限制。在附图中：
图1是根据本公开的一种实施方式提供的车辆控制方法的流程图；
图2是根据本公开的另一种实施方式提供的车辆控制方法的流程图；
图3是根据本公开的一种实施方式提供的车辆控制装置的框图。
具体实施方式
以下结合附图对本公开的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本公开，并不用于限制本公开。
在介绍本公开的方案之前，首先对本公开所涉及到的相关概念及硬件进行简单说明。
动力域控制器：用于控制车辆动力系统和传动系统，集成了上下电控制、整车能量管理、整车故障管理、整车扭矩控制、动力电池管理、充电控制、驱动电机控制、增程器控制、变速器控制等功能。
辅助驾驶域控制器：用于控制车辆的辅助驾驶系统，集成了自适应巡航、车道保持、领航辅助、自动泊车、遥控泊车、自动代客泊车、自动紧急制动、哨兵模式等高级驾驶辅助功能。
车身域控制器：用于控制车身系统，集成了电动车窗、电动后视镜、空调、大灯、转向灯、除霜装置、防盗系统、电源模式、中央控制门锁、迎宾系统等功能。
智能DCDC(DC to DC Converter，直流-直流转换器)：可在车辆下电时，检测低压蓄电池电压/荷电状态，若低压蓄电池电压/荷电状态偏低，智能DCDC会唤醒VCU(Vehicle Control Unit，整车控制器)，VCU控制车辆高压上电，而后动力电池会通过智能DCDC向 低压蓄电池充电，以保证车辆可正常启动。
图1是根据本公开的一种实施方式提供的车辆控制方法的流程图。在一些实施例中，本公开实施例提供的方法可以应用于车辆的动力域控制器。
如图1所示，该方法可以包括以下步骤：
在步骤11中，在车辆停止、且电池低电量保护功能处于未激活状态时，确定车辆电源是否处于电量不足状态；
在步骤12中，若确定车辆电源处于电量不足状态，控制电池低电量保护功能进入初级保护状态；
在步骤13中，在电池低电量保护功能处于初级保护状态的情况下，限制车辆中指定耗电功能的使用。
其中，在初级保护状态下车辆的部分功能受限。
在本公开的方案中，车辆的电池低电量保护功能存在三种状态，分别是未激活状态、初级保护状态和保护激活状态。在未激活状态下，车辆的电池低电量保护功能不会生效，并且，若在未激活状态下检测到车辆电源处于电量不足状态，电池低电量保护功能会从未激活状态变化至初级保护状态。在初级保护状态下，会对指定耗电功能进行限制，对防止动力电池过放电采取初步措施。初级保护状态可以认为是进入保护激活状态的过渡状态，二者之间的切换方式将在后文中给出，此处暂不详细阐述。
通过上述技术方案，在车辆停止、且电池低电量保护功能处于未激活状态时，确定车辆电源是否处于电量不足状态，若确定车辆电源处于电量不足状态，控制电池低电量保护功能进入初级保护状态，在电池低电量保护功能处于初级保护状态的情况下，限制车辆中指定耗电功能的使用。其中，在初级保护状态下车辆的部分功能受限。由此，在车辆停驻、且电源电量过低时，能够及时地限制耗电功能的使用，避免车辆电源过放电，进而能够避免由电源过放电引起的车辆无法使用的情况，保证车辆能够正常使用。
下面对本公开的各个步骤进行详细说明。
在步骤11中，在车辆停止、且电池低电量保护功能处于未激活状态时，确定车辆电源是否处于电量不足状态。
其中，车辆停止与否可以通过车辆的电源模式确定，即，在车辆的电源模式处于OFF挡时，认为车辆停止。
在本公开的实施方式中，步骤11可以包括以下步骤：
在车辆停止、电池低电量保护功能处于未激活状态时，获取车辆动力电池的剩余电量和车辆的充电状态；
若动力电池的剩余电量处于第一低电量范围、且车辆的充电状态指示车辆未充电，确定车辆电源处于电量不足状态。
其中，第一低电量范围根据实际的需求自行设置，例如，可以设置为小于10％。
也就是说，在电池低电量保护功能处于未激活状态时，若车辆停止、车辆动力电池的 剩余电量较低、且车辆并未充电，可以判定车辆电源处于电量不足状态。
在确定车辆处于电量不足状态的情况下，根据步骤12，可以控制电池低电量保护功能进入初级保护状态。
在本公开的实施例中，还可以对初级保护状态进行划分，分为两种不同的状态。即，初级保护状态可以包括第一保护状态和第二保护状态，且车辆在处于第一保护状态时受限的功能多于处于第二保护状态时受限的功能。
在这一实施例中，第一低电量范围可以包括第一范围和第二范围，且第一范围的电量下限高于第二范围的电量上限。相应地，步骤12可以包括以下步骤：
获取车辆蓄电池的剩余电量；
若动力电池的剩余电量处于第一范围、且蓄电池的剩余电量达到第一电量阈值，控制电池低电量保护功能进入第一保护状态；
若动力电池的剩余电量处于第二范围、且蓄电池的剩余电量未达到第一电量阈值，控制电池低电量保护功能进入第二保护状态。
第一范围和第二范围可以根据实际需求自由设置。在一些实施例中，第一范围可以为[5％，10％]，第二范围可以为小于5％。
第一电量阈值可以根据实际需求进行设置。在一些实施例中，第一电量阈值可以为40％。
若动力电池的剩余电量处于第一范围、且蓄电池的剩余电量达到(即，大于或者等于)第一电量阈值，说明车辆动力电池和蓄电池(低压蓄电池)的剩余电量较低，但还未到极低的状态，因此，可以控制电池低电量保护功能进入第一保护状态。
若动力电池的剩余电量处于第二范围、且蓄电池的剩余电量未达到(即，小于)第一电量阈值，说明车辆动力电池和蓄电池的剩余电量已经极低，因此，可以控制电池低电量保护功能进入第二保护状态。
其中，由于车辆进入第一保护状态时电源总体的电量会高于进入第二保护状态时的总体电量，因此，车辆在处于第二保护状态时的功能限制程度会比车辆处于第一保护状态时的功能限制程度更高一些，也就是说，车辆在处于第一保护状态时受限的功能多于处于第二保护状态时受限的功能。
另外，在电池低电量保护功能处于第一保护状态的情况下，若检测到蓄电池的剩余电量低于第一电量阈值，控制电池低电量保护功能进入第二保护状态。
在进入初级保护状态后，根据步骤13，可以限制车辆中指定耗电功能的使用。
在本公开的实施方式中，步骤13可以包括以下步骤：
若电池低电量保护功能处于初级保护状态，对由辅助驾驶域控制器、车身域控制器、直流-直流转换器中的至少一者所控制的耗电功能的使用进行限制。
在一些实施例中，对耗电功能的使用进行限制可以包括降低功能使用频率或者禁止使用功能。
辅助驾驶域控制器所控制的耗电功能可以包括但不限于：哨兵模式、遥控驾驶、遥控泊车、自动代客泊车。
车身域控制器所控制的耗电功能可以包括但不限于：中央控制门锁、迎宾系统。
直流-直流转换器所控制的耗电功能可以包括对车辆蓄电池剩余电量的检测。
在本公开的实施例中，若初级保护状态为第一保护状态(即，车辆电池低电量保护功能处于第一保护状态)，对由辅助驾驶域控制器、车身域控制器、直流-直流转换器中的至少一者所控制的耗电功能的使用进行限制，可以包括以下步骤：
向辅助驾驶域控制器发送第一禁用指令，以禁用由辅助驾驶域控制器控制的耗电功能；
向车身域控制器发送第二禁用指令，以禁用由车身域控制器控制的耗电动能；
向直流-直流转换器发送频率限制指令，以降低直流-直流转换器对车辆蓄电池的检测频率。
若电池低电量保护功能处于第一保护状态，可以禁用辅助驾驶域控制器和车身域控制器所控制的耗电功能，以降低车辆电源耗电量。同时，由于当前车辆电源还存在一些电量剩余，因此，对于直流-直流转换器，由于其用于检测蓄电池相关用电参数信息，可以暂不对其禁用，而仅仅限制其检测频率。
在本公开的实施例中，若初级保护状态为第二保护状态(即，车辆电池低电量保护功能处于第二保护状态)，对由辅助驾驶域控制器、车身域控制器、直流-直流转换器中的至少一者所控制的耗电功能的使用进行限制，可以包括以下步骤：
向辅助驾驶域控制器发送第一禁用指令，以禁用由辅助驾驶域控制器控制的耗电功能；
向车身域控制器发送第二禁用指令，以禁用由车身域控制器控制的耗电动能；
向直流-直流转换器发送第三禁用指令，以禁止直流-直流转换器对车辆蓄电池进行检测。
若电池低电量保护功能处于第二保护状态，可以禁用辅助驾驶域控制器和车身域控制器所控制的耗电功能，以降低车辆电源耗电量。同时，由于当前车辆电源电量剩余已经很低，直流-直流转换器蓄电池的检测已无必要，因此，可以直接禁止直流-直流转换器的检测。
在一些实施例中，本公开实施例提供的方法还可以包括以下步骤：
生成并输出第一提示信息。
其中，第一提示信息用于指示已被限制的耗电功能。在一些实施例中，可以通过车辆的HMI(Human Machine Interface，人机交互界面)输出第一提示信息。
图2是根据本公开的另一种实施方式提供的车辆控制方法的流程图。在图1所示各步骤的基础上，本公开实施例提供的方法还可以包括以下步骤。
在步骤21中，在电池低电量保护功能处于初级保护状态的情况下，确定车辆是否满足进入保护激活状态的条件；
在步骤22中，若确定满足进入保护激活状态的条件，控制电池低电量保护功能进入保护激活状态。
其中，车辆在保护激活状态下所耗费的电量低于车辆在处于初级保护状态下所耗费的电量。也就是说，车辆在处于保护激活状态时，相比于车辆处于初级保护状态来说，将采取更加有效的措施，以降低车辆电源的耗电量。
在一些实施例中，确定车辆是否满足进入保护激活状态的条件，可以包括以下步骤：
检测指定耗电功能的限制状态；
若限制状态指示对各个指定耗电功能的限制均已完成，确定车辆满足进入保护激活状态的条件。
其中，限制状态用于指示对于指定耗电功能的限制是否成功执行，也就是指定耗电功能是否已经停止耗电。
再例如，确定车辆是否满足进入保护激活状态的条件，可以包括以下步骤：
自电池低电量保护功能进入初级保护状态时开始计时，获得计时时长；
若计时时长达到预设时长，确定车辆满足进入保护激活状态的条件。
在一些实施例中，本公开实施例提供的方法还可以包括以下步骤：
在电池低电量保护功能处于保护激活状态的情况下，控制指定设备休眠。
其中，指定功能由指定设备进行控制。在一些实施例中，指定设备可以包括但不限于辅助驾驶域控制器、车身域控制器、直流-直流转换器中的至少一者。这一步骤实际上就是控制辅助驾驶域控制器、车身域控制器、直流-直流转换器休眠。同时，还可以控制HMI功能休眠。
在一些实施例中，在图2所示各步骤的基础上，本公开实施例提供的方法还可以包括以下步骤：
在电池低电量保护功能处于保护激活状态的情况下，确定车辆是否满足退出保护条件；
若确定车辆满足退出保护条件，控制电池低电量保护功能由保护激活状态切换至未激活状态。
在一些实施例中，可以通过如下方式确定车辆是否满足退出保护条件：
若车辆通电，确定车辆满足退出保护条件。
再例如，可以通过如下方式确定车辆是否满足退出保护条件：
若动力电池的剩余电量大于第二电量阈值、且车辆的充电状态指示车辆正在充电，确定车辆满足退出保护条件。
通过上述方式，在对动力电池进行低电量保护的情况下，还会根据车辆的通电情况、电量及充电情况等，判断退出保护激活状态的条件，并及时地退出保护激活状态，以更加灵活地实现对电池低电量保护功能的控制。

第一确定模块31，用于在车辆停止、且电池低电量保护功能处于未激活状态时，确定车辆电源是否处于电量不足状态；
