具体实施方式
下面详细描述本公开的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描 述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
下面参考附图描述本公开实施例的车载直流变直流变换器的状态识别方法、车载直流变直流变换器的状态识别装置、电子设备、非临时性计算机可读存储介质、计算机程序产品和计算机程序。
图1是根据本公开实施例的车载直流变直流变换器的状态识别方法的流程图。
需要说明的是，本公开实施例的车载直流变直流变换器的状态识别方法的执行主体是车辆的控制器，该车辆的控制器可以是整车控制器VCU(Vehicle Control Unit，整车控制器)，也可以是单独设置的一个控制器，具体这里不进行限制。
如图1所示，本公开实施例的车载直流变直流变换器的状态识别方法，包括步骤S101-S103。
步骤S101：获取蓄电池的工作电流和电压。
例如，可通过设置在蓄电池正极端或负极端的电流传感器，实时采集蓄电池的工作电流；通过设置在蓄电池正负两端的电压传感器，实时采集蓄电池的电压。电池管理器与蓄电池的电流传感器和电压传感器连接，以实时获取蓄电池的工作电流和电压。
该车辆的控制器通过LIN(Local Interconnect Network，局域互联网络)总线或者CAN(Controller Area Network，控制器局域网络)总线与电池管理器连接，这样该车辆的控制器便可通过LIN总线或者CAN总线实时获取蓄电池的工作电流和电压。
步骤S102：获取车载直流变直流变换器的使能端状态。
其中，车载直流变直流变换器的使能端状态可以为工作或非工作。
该车辆的控制器与车载直流变直流变换器连接，如至少和车载直流变直流变换器的使能端连接，以获取车载直流变直流变换器的使能状态。
步骤S103：根据蓄电池的工作电流、电压和车载直流变直流变换器的使能端状态，识别车载直流变直流变换器的状态。
例如，该车辆的控制器在车载直流变直流变换器的使能端状态为非工作时，识别车载直流变直流变换器的状态为不工作；基于车载直流变直流变换器的使能端状态为工作，响应于蓄电池的电压降低并持续降低，且蓄电池对外持续放电，识别车载直流变直流变换器的状态为异常。
由此，本公开实施例的车载直流变直流变换器的状态识别方法，能够提前在车辆未报出故障前，对车载直流变直流变换器的状态进行提前识别，避免驾驶员在车载直流变直流变换器异常时继续行驶汽车，这样不仅提高了行车安全，而且降低蓄电池损坏的概率，从而提高了用户体验感。
图2是根据本公开一个实施例的车载直流变直流变换器的状态识别方法的流程图。
如图2所示，本公开实施例的车载直流变直流变换器的状态识别方法，包括步骤S201-S206。
步骤S201：获取蓄电池的工作电流和电压。
步骤S202：获取车载直流变直流变换器的使能端状态。
需要说明的是，本公开实施例的步骤S201和S202的内容，请详见上述实施例的步骤S101和S102。
步骤S203：根据蓄电池的工作电流，计算蓄电池的平均电流。
步骤S204：根据蓄电池的平均电流、电压和车载直流变直流变换器的使能端状态，识别车载直流变直流变换器的状态。
由于在蓄电池充满电或者给大负载供电时，蓄电池的工作电流可能接近0，因此为了提高判断识别车载直流变直流变换器的状态，该车辆的控制器在获取到蓄电池的工作电流之后，计算蓄电池的平均电流。
该车辆的控制器在车载直流变直流变换器的使能端状态为非工作时，识别车载直流变直流变换器的状态为不工作；基于车载直流变直流变换器的使能端状态为工作，响应于蓄电池的电压降低并持续降低，且蓄电池的工作电流大于设定电流(该设定电流可根据实际情况进行设置)，识别车载直流变直流变换器的状态为异常。
步骤S205：基于车载直流变直流变换器的状态为异常，生成车载直流变直流异常信息。
步骤S206：发送车载直流变直流异常信息至终端。
例如，该车辆的控制器在识别出车载直流变直流变换器的状态为异常时，生成车载直流变直流异常信息，并将该车载直流变直流异常信息发送至终端(如手机)，以提醒驾驶员注意当前车载直流变直流变换器异常。
又如，驾驶员的终端(如手机)上下载了车辆相关的APP(Application，应用程序)。该车辆的控制器在识别出车载直流变直流变换器的状态为异常时，生成车载直流变直流异常信息，并将该车载直流变直流异常信息发送至终端APP，之后通过终端APP推送至售后人员，这样便可以及时提醒售后人员立即分析故障产生原因，并主动联系车主。
由此，本公开实施例的车载直流变直流变换器的状态识别方法，能够提前在车辆未报出故障前，对可能存在直流变直流变换器异常潜在风险的车辆提前识别，故障诊断，在不影响用户使用车辆条件下，将潜在风险规避。甚至在出现直流变直流变换器故障或直流变直流变换器未工作引起的其他故障时，售后人员及时获得信息，可以做到主动联系车主，大幅减少用户顾虑，提升用户体验感，提升品牌价值。
为了不增加整车控制器VCU的工作量或不增加额外的控制器，本公开实施例的车载直流变直流变换器的状态识别方法的执行主体还可以是TSP(Telematics Service Provider，内容服务提供者)平台。例如，可在TSP平台上增加车载直流变直流变换器的状态识别逻辑。即，由TSP平台作为本公开实施例的车载直流变直流变换器的状态识别方法的执行主体。
图3是根据本公开一个实施例的车载直流变直流变换器的状态识别***的示意图。
如图3所示，本公开实施例的车载直流变直流变换器的状态识别***，包括：蓄电池、电池管理器BMS(Battery Management System，电池管理器)、整车控制器VCU、车载T-BOX(Telematics BOX，远程信息处理器)、TSP平台和手机APP。
在由TSP平台执行本公开实施例的车载直流变直流变换器的状态识别方法时，通过电池管理器实时获取蓄电池的工作电流和电压，并将蓄电池的工作电流和电压通过LIN总线 发送给整车控制器VCU。整车控制器VCU与车载直流变直流变换器连接，如至少和车载直流变直流变换器的使能端连接，以获取车载直流变直流变换器的使能状态。整车控制器VCU将蓄电池的工作电流、电压和车载直流变直流变换器的使能状态，通过CAN总线发送至车载T-BOX。由车载T-BOX将蓄电池的工作电流、电压和车载直流变直流变换器的使能状态上传至云端的TSP平台，该上传信息的过程并不产生费用，是因为车载T-BOX本身就需要上传其他信息。
TSP平台判断基于车载直流变直流变换器的使能状态为工作，响应于蓄电池对外放电，且蓄电池的电压降低并持续降低，确认车载直流变直流变换器的状态为异常。TSP平台立即向后台服务器推送车载直流变直流变换器异常的信息。后台服务器将车载直流变直流变换器异常的信息推送至手机APP。通过手机APP将车载直流变直流变换器异常的信息推送至售后人员，该过程中只产生流量，不会额外增加成本及费用，这样便可以及时提醒售后人员立即后台分析故障产生原因，提升用户体验感。
由此，本公开实施例的车载直流变直流变换器的状态识别方法，可以解决在车辆未报出故障前，对可能存在直流变直流变换器异常潜在风险的车辆提前识别、故障诊断，在不影响用户使用车辆的条件下，将潜在风险规避，甚至在出现直流变直流变换器故障或直流变直流变换器未工作引起的其他故障时，售后人员及时获得消息，可以做到主动联系车主，大幅减少用户顾虑，提升品牌价值。
综上所述，根据本公开实施例的车载直流变直流变换器的状态识别方法，获取蓄电池的工作电流和电压，并获取车载直流变直流变换器的使能端状态，之后根据所述蓄电池的工作电流、电压和所述车载直流变直流变换器的使能端状态，识别所述车载直流变直流变换器的状态。由此，该方法能够提前在车辆未报出故障前，对车载直流变直流变换器的状态进行提前识别，避免驾驶员在车载直流变直流变换器异常时继续行驶汽车，这样不仅提高了行车安全，而且降低蓄电池损坏的概率，从而提高了用户体验感。
