为使本发明实施例的目的、技术方案和优点更加清楚，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、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。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前提下所获得的所有其 他实施例，都属于本发明保护的范围。
此外，下面所描述的本发明各个实施方式中所涉及到的技术特征只要彼此之间未构成冲突就可以相互组合。
请参阅图1，图1为本发明实施例提供的一种车辆系统说明图生成方法流程图，所述方法可应用于车辆自身系统或车辆维修系统或车辆生产系统，所述方法包括：
步骤S101，获取车辆的车辆信息，所述车辆信息包括车辆品牌信息、车辆型号信息和车型配置信息。
具体的，车辆的车辆品牌信息、车辆型号信息和车型配置信息可从汽车中央网关数据库中查询得到，所述汽车中央网关数据库为预先设置的数据库，其中存储有各种品牌和车型的车型配置信息。
步骤S102，根据所述车辆信息确定所述车辆的各功能系统所包含的各部件或模块。
一般地，汽车包括发动机、底盘、车身和电气设备四部分。其中，发动机包括燃料供给系统、润滑系统、冷却系统、点火系统和启动系统；底盘包括传动系统、行驶系统、转向系统和制动系统；电气设备包括车灯、仪表、雷达等各种辅助系统。一般地，每个功能系统由一个控制单元部件和其他若干部件或模块组成，该控制单元部件用于管控所述功能系统中其他部件或模块的运转。不同车辆类型的各功能系统还包括各部件或模块是不同的。。
步骤S103，从预先建立的元素数据库中获取每一功能系统所包含的各部件或模块对应的各元素的元素信息。
所述元素数据库中包括若干元素的元素信息，每个元素与一部件或模块相对应，所述元素信息包括元素编码和元素图片。所述元素编码可与各汽车品牌对各部件或模块的编码保持一致。同一品牌下，不同部件或模块的编码不同。所述元素数据库可由各汽车品牌服务商创建，也可由专业的汽车维修公司创建。
在一些实施例中，所述元素数据库中存储了各种车辆品牌、各种车型所包含的各部件或模块的元素信息。在建立该元素数据库时，先收集各种车辆品牌、各种车型的维修资料、培训资料、电气功能图等信息，并对所收集的信息基于同一工作原理的模块或部件进行分类，以备建模。比如各个品牌车型的不同系统中的压力传感器可以分作一类，它可能出现在发动机系统中的进气管路的节气门前或节气门后；也可能出现在空气弹簧，车身可变的悬挂(避震)系统中。对于已分好类的模块或部件，根据其外形结构进行模型制作，形成统一的样式，再建模完成的各部件或模块的图片按组存储到元素数据库中。请参阅图2a和图2b，其中，图2a为本发明实施例提供的一种车辆仪表盘的示意图，图2b为根据图2a中车辆仪表盘生成的元素图片示意图。
采用上述方式建好的元素数据库中包含若干元素分组，每个元素分组由具有同一工作原理的各部件或模块对应的各元素组成，且每个元素分组内同一元 素图片对应一个或多个元素编码。如图3所示，为本发明实施例提供的将一元素数据库中部分元素导入到excel表之后的示意图，其中，左侧一栏为元素分组名称，在每个元素分组下，又按车辆品牌对各元素进行划分。比如“喷油嘴”这一元素分组下，BENZ车品牌下有四个元素编码均对应同一“喷油嘴”元素图片，分别是Y76/1、Y76/2、Y76/3、Y76/4。
在一些实施例中，为了提高数据查询效率和存储效率，在组建各种品牌、各种车型的各部件或模块的元素数据库时，还建立各元素与车辆品牌信息、和/或车辆型号信息、和/或功能系统标识的映射关系，所述从预先建立的元素数据库中获取每一功能系统所包含的各部件或模块对应的各元素的元素信息包括：根据所述车辆信息和每一功能系统标识，从预先建立的元素数据库中获取所述车辆的每一功能系统所包含的各部件或模块对应的各元素的元素信息。具体的，可先根据部件或模块名称找到对应的元素分组，进一步在该元素分组下根据所述车辆信息和功能系统标识找到对应的元素。可以理解的是，由于车辆所包含各部件或模块数量和类型较多，有的部件或模块可在同一品牌的不同车型和不同功能系统共用，有的部件或模块可在同一品牌的同一车型共用，有的部件或模块可在同一品牌的同一功能系统下共用。因此，有的元素分组内中各元素仅与车辆品牌存在映射关系，有的元素分组内中各元素与车辆品牌+车辆型号存在映射关系，有的元素分组内中各元素与车辆品牌+功能系统存在映射关系，在建立各元素与车辆品牌信息、和/或车辆型号信息、和/或功能系统标识的映射关系时，根据实际情况建立即可。
步骤S104，获取各功能系统所包含的各部件或模块与各汽车总线的连接关系信息，以及各部件或模块之间的信号流向信息。
具体的，预先对每个功能系统所包含的各部件或模块之间与各汽车总线的连接关系信息，以及各部件或模块之间的信号流向信息进行统计，并按预设的规则进行存储。比如，可采用(A，Line集合)标识其中一个部件或模块与各汽车总线的连接关系信息，其中，A表示该部件或模块，Line集合中表示该部件或模块连接的所有总线。采用(信号流序号，B集合，C集合，Line)标识一条信号流信息，其中，B集合表示该信号流对应的流出各部件或模块组成的集合，C集合表示该信号流对应的流入各部件或模块组成的集合，Line表示该信号流所流经的总线。
步骤S105，根据各功能系统所包含的各部件或模块对应的各元素的元素信息、所述连接关系信息和所述信号流向信息，生成所述车辆各功能系统对应的系统说明图。
具体的，根据各功能系统所包含的各部件或模块对应的各元素的元素信息、所述连接关系信息，生成所述车辆的各功能系统对应的网络结构图，以及，
根据各功能系统所包含的各部件或模块对应的各元素的元素信息、所述信号流向信息，生成所述车辆的各功能系统对应的信号流结构图。
车辆中的网络关系错综复杂，现有技术中，各部件或模块的相互连接大多 通过电路图进行表达，当电路图中的部件过多时，查阅的信息量就过大，过少时又不能完整表达相互连接的整体关系。为解决该问题，本发明实施例提供了生成网络结构图的方法。如图4所示，为本发明实施例提供的一种网络结构图的示意图。该网络结构图依据一功能系统中各部件或模块与各汽车总线的连接关系绘制生成，其中，各部件或模块使用各部件或模块对应的元素编码进行标识，各部件或模块与不同汽车总线的连接线使用不同颜色标识不同总线。通过该网络结构图，可以从整体上系统地探明该功能系统的全貌。
为了帮助用户理解每个功能系统的工作原理，大多还会提供各功能系统的工作原理图，但是工作原理图不能表达控制单元的工作逻辑，从而使得用户不能全面了解各功能系统的工作原理。为了更好表达各功能系统中控制单元的工作逻辑，本发明实施例提供了生成信号流结构图的方法。，如图5所示，为本发明实施例提供的一种信号流结构图的示意图。该信号流结构图中各部件或模块使用对应的元素编码+元素图片进行标识，各部件或模块之间的每个信号流向使用箭头和信号流序号进行标识。具体的，通过数字加圆圈在图中进行标注，数字的大小表示信号发送的先后关系。
在车辆系统中，有些功能系统的工作原理是通过无线技术通信来进行工作的，本发明实施例还用于根据各部件或模块之间的无线连接方式生成无线传输功能原理图。如图6所示，为本发明实施例提供的一种无线传输功能原理图的示意图。
本发明实施例中，首先根据车辆信息确定车辆包含的各功能系统，以及各功能系统所包含的各部件或模块；其次，从预先建立的元素数据库中获取每一功能系统所包含的各部件或模块对应的各元素的元素信息；最后，根据各功能系统所包含的各部件或模块对应的各元素的元素信息、各部件或模块对应的连接关系信息和信号流向信息生成所述车辆的各功能系统对应的系统说明图，其中，通过系统说明图中的网络结构图支持各种复杂的总线网络结构关系，可以整体地系统性探明汽车架框的全貌；通过系统说明图中的信号流结构图，能清楚细致地感受汽车的信息流动。
请参阅图7，图7是本发明实施例中一种车辆系统说明图的展示方法的流程图，所述方法可应用于车辆自身系统或车辆维修系统中，所述方法包括：
步骤S701，获取车辆的其中一个功能系统的功能系统标识。
在一些实施例中，将所述车辆的各功能系统对应的系统说明图预先存储在所述车辆上。
在一些实施例中，将各种车辆的各功能系统对应的系统说明图预先存储在汽车维修系统的服务器中。所述步骤S701，还用于获取车辆信息，比如车辆品牌信息、车辆型号信息和车型配置信息。根据车辆信息筛选出所述车辆的各功能系统对应的系统说明图。
步骤S702，根据所述功能系统标识获取所述功能系统对应的系统说明图，所述系统说明图采用本发明实施例中任一项所述车辆系统说明图的生成方法 生成。
其中，所述系统说明图包括网络结构图和信号流结构图。
步骤S703，根据所述功能系统标识获取所述功能系统对应的系统说明文件。
具体的，所述方法还包括：根据所述车辆所包含的各功能系统，以及各功能系统所包含的各部件或模块，为所述车辆的各功能系统设置对应的系统说明文件，所述系统说明文件包括功能说明文件、部件说明文件、信号流说明文件和案例说明文件中至少一种。其中，功能说明文件用来介绍当前功能系统在各种情况下的正常工作原理和情形；部件说明文件用来对当前功能系统所包含的各部件或模块进行介绍；信号流说明文件用来对信号流结构图中每条信号流进行说明，案例说明文件用来对当前功能系统发生相关故障的维修案例以及维修时应注意的安全事项进行说明。
步骤S704，将所述系统说明图和所述系统说明文件进行关联展示。
由于各功能系统的系统说明图对应的系统说明文件可有多种，在一些实施例中，为了展示方便，根据用户输入的系统说明文件类型获取与所述系统说明文件类型对应的说明文件；将所述说明文件与所述系统说明图进行关联展示。具体的，可在系统说明展示页面设置系统说明文件切换按钮，根据用户选择，展示对应的系统说明文件。比如，当前展示的系统说明图为信号流结构图，则当用户选择“查看部件说明文件”时，将信号流结构图与该信号流结构图对应的部件说明文件进行关联展示，比如将信号流结构图展示在界面上方，该信号流结构图中包含的各部件对应的部件说明文件展示在界面下方。同理，当用户选择其他说明文件时，将该信号流结构图与该信号流结构图对应的其他说明文件进行同样或类似的关联展示。可以理解的是，当用户查看该功能系统的网络结构图时，可以与该功能系统对应的功能说明文件、部件说明文件和案例说明文件三种文件中进行关联查看。
本发明实施例中，通过将系统说明图和对应的系统说明文件进行关联展示，提供一种图文展示的方式，跟有利于帮助用户理解各功能系统的网络结构和信号流向。
