具体实施方式
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作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。
本发明实施例提供的汽车诊断方法和装置适用于如图1所示的应用场景。所述应用场景包括汽车诊断设备10、诊断连接设备20和汽车网络30。汽车网络30是被检测对象,其包括汽车的电控模块,可以检测汽车各部分的运行数据和故障码等检测数据。诊断连接设备20例如VCI(Vehicle Connection Interface)设备,其是汽车诊断设备10中诊断软件和汽车网络30通信的桥梁,负责将汽车诊断设备10的诊断指令传送给汽车网络30,以及将汽车网络30返回的检测数据传送给汽车诊断设备10。汽车诊断设备10和诊断连接设备20之间可以通过通信串口、USB接口等有线方式连接,也可以通过蓝牙、WIFI等无线方式连接,诊断连接设备20与汽车网络30之间通过诊断接口例如OBD(On-Board Diagnostic)接口相连。
汽车诊断设备10是能够运行诊断软件的设备,例如个人计算机、智能手机等,或者专门提供的诊断设备。在实际应用中,汽车诊断设备10和诊断连接设备20可以搭配出售,诊断连接设备20也可以单独出售,与个人计算机、智能手机等汽车诊断设备配合使用,对汽车网络进行诊断。所述诊断软件提供人机交互界面,通过操作该界面用户可以选择诊断功能,诊断软件将用户选择 的诊断功能转换成诊断指令,并将该诊断指令通过诊断连接设备20发送给汽车网络30。汽车网络30根据该诊断指令获得该诊断指令对应的检测数据,并将所述检测数据通过诊断连接设备20发送给汽车诊断设备10。汽车诊断设备10的诊断软件对汽车网络30反馈的检测数据进行解析,获得诊断结果,并将诊断结果向用户展示。
图2A为本发明实施例提供的一种汽车诊断方法的流程示意图,所述方法可以由图1中的汽车诊断设备10执行,如图2所示,所述诊断方法包括:
101:读取用户对界面的操作,并将所述操作转换成对应的诊断指令。
在实际应用中,所述汽车诊断方法可以通过汽车诊断软件的形式来实现,该汽车诊断软件具有人机交互界面,该人机交互界面可在汽车诊断设备10的显示屏幕上显示。用户可以通过按键和显示屏幕对该诊断软件进行操作,例如选择总线类型、总线控制器类型、诊断功能,以及进行诊断连接设备20的参数设置等,汽车网络30包括多个电控模块的场合,还可以对电控模块进行选择。汽车诊断设备10将用户对界面的操作转换成诊断指令。
102:将所述诊断指令转换成所述诊断指令对应的标准传输数据。
因为所述诊断指令需要通过总线传输给汽车网络30,所以该诊断指令需要转换成物理层的总线传输数据协议格式,即进行数据链路层和物理层协议转换。在汽车网络包括控制器局域网络(Controller Area Network,CAN)总线、通讯(Kommunikation,K)总线等的场合,诊断指令可以转换成CAN总线数据协议格式、K总线数据协议格式等。
目前的诊断方法中,上述数据链路层和物理层的转换是在诊断连接设备20中进行的,由于该转换对诊断连接设备20中主芯片资源消耗大,对主芯片的性能要求较高,造成诊断连接设备20硬件成本高。本实施例将链路层与物理层的协议转换放在诊断软件中,即放在汽车诊断设备10中,因为个人计算机、智能手机等汽车诊断设备10本身性能较高,能胜任大多数软件运行,因此将协议转换在汽车诊断设备10端运行在不增加汽车诊断设备10的硬件成本的基础上,降低了诊断连接设备20的硬件成本。
其中,可选的,可以将全部协议转换全在汽车诊断设备10上运行,也可以将部分协议转换在汽车诊断设备10上运行。例如诊断指令到CAN总线协议标准传输数据的转换和诊断指令到K总线协议标准传输数据的转换都在汽车诊断设备10侧运行,或者仅诊断指令到CAN总线协议标准传输数据的转换在汽车诊断设备10侧运行,而诊断指令到K总线协议标准传输数据的转换在诊断连接设备20侧运行。
103:发送所述诊断指令对应的标准传输数据。
在实际应用中,可以通过汽车诊断设备10的通讯单元将诊断指令对应的 标准传输数据发送给诊断连接设备20,其中,通讯单元例如串口通讯单元、USB通讯单元、蓝牙通讯单元和WIFI通讯单元等。
通过如上101、102和103,汽车诊断设备10将诊断指令通过诊断连接设备20发送给汽车网络30。汽车网络30接收到汽车诊断设备10发送的诊断指令后,根据该诊断指令对汽车的电控模块进行检测,并获得对应的检测数据。汽车网络30将所述检测数据转换成符合总线传输标准的标准传输数据,通过诊断连接设备20发送给汽车诊断设备10。汽车诊断设备10接收到该检测数据对应的标准传输数据后进行处理,请参照图2B,具体如下:
104:接收汽车网络的检测数据对应的标准传输数据。
105:将所述检测数据对应的标准传输数据转换成检测数据。
汽车诊断设备10将检测数据对应的标准传输数据进行物理层和数据链路层协议转换,获得检测数据。可选的,针对该检测数据的协议转换可以全部在汽车诊断设备10上运行,也可以部分在汽车诊断设备10上运行。例如CAN总线协议标准传输数据到检测数据的转换和K总线协议标准传输数据到检测数据的转换都在汽车诊断设备10侧运行,或者仅CAN总线协议标准传输数据到检测数据的转换在汽车诊断设备10侧运行,而K总线协议标准传输数据到检测数据的转换在诊断连接设备20侧运行。
106:对所述检测数据进行解析,获得诊断结果。
汽车诊断设备10对所述检测数据进行解析,获得汽车网络30的诊断结果。
本发明实施例通过将耗内存资源和处理器资源的物理层和数据链路层的协议转换全部或者部分放在汽车诊断设备10上运行,使诊断连接设备20只需运行部分物理层和数据链路层的协议转换或者不需要运行物理层和数据链路层的协议转换。降低了诊断连接设备20对硬件性能的要求,节省了诊断连接设备20的硬件成本。
