其中，交通工具诊断设备20可以在其安装的诊断软件中对应的创建多个诊断对象，每个诊断对象用于诊断一个ECU。诊断软件对外接口采用异步通讯的方式，多个诊断对象通过该接口均可以访问VCI。所述至少两个第一指令可以是诊断软件的不同诊断对象发出的。第一指令可以是专用于指示交通工具诊断设备20与对应的ECU建立连接的指令，也可以为交通工具诊断设备20对ECU的诊断指令。The vehicle diagnostic device 20 can create a plurality of diagnostic objects correspondingly in the diagnostic software installed therein, and each diagnostic object is used to diagnose one ECU. The diagnostic software uses asynchronous communication on the external interface. Multiple diagnostic objects can access the VCI through this interface. The at least two first instructions may be issued by different diagnostic objects of the diagnostic software. The first command may be an instruction dedicated to instructing the vehicle diagnostic device 20 to establish a connection with a corresponding ECU, or may be a diagnostic command of the vehicle diagnostic device 20 to the ECU.

在一个实施方式中，交通工具通信接口VCI10可以通过异步通讯层同时接收所述交通工具诊断设备发送的所述至少2个第一指令。In one embodiment, the vehicle communication interface VCI 10 can simultaneously receive the at least two first instructions sent by the vehicle diagnostic device through an asynchronous communication layer.

102：根据所述至少2个第一指令，建立至少2个逻辑通道，所述第一指令与所述逻辑通道一一对应，所述逻辑通道用于传输所述交通工具诊断设备20与所述ECU之间的数据。Step 102: Establish at least two logical channels according to the at least two first instructions, where the first instruction is in one-to-one correspondence with the logical channel, where the logical channel is used to transmit the vehicle diagnostic device 20 and the Data between ECUs.

即根据每个第一指令建立一条交通工具诊断设备20与所述第一指令对应的ECU之间的通道，从而为所述至少两个第一指令分别建立逻辑通道，所述逻辑通道与ECU一一对应。That is, a channel between the vehicle diagnostic device 20 and the ECU corresponding to the first instruction is established according to each first instruction, thereby establishing a logical channel for the at least two first instructions, the logic channel and the ECU A correspondence.

其中，可以在所述VCI的各软件层上建立用于与相邻的软件层进行通信的通道元素，以建立所述至少2个逻辑通道。以图2所示的软件架构为例，可以在操作***层上建立至少2个与所述第一指令一一对应的线程，建立用于管理所述至少2个线程的主线程。在协议栈层根据所述至少2个第一指令中各自的协议类型，建立至少2个与所述第一指令一一对应的协议对象。在硬件驱动层上根据所述至少2个第一指令中各自的总线类型和/或管脚信息，建立至少1个总线驱动对象。以此形成至少两条交通工具诊断设备20访问交通工具控制网络30的通道，用于使交通工具诊断设备20访问至少两个ECU。Wherein, channel elements for communicating with adjacent software layers may be established on each software layer of the VCI to establish the at least two logical channels. Taking the software architecture shown in FIG. 2 as an example, at least two threads corresponding to the first instruction may be established on the operating system layer, and a main thread for managing the at least two threads may be established. And at least two protocol objects corresponding to the first instruction are established in the protocol stack layer according to respective protocol types in the at least two first instructions. At least one bus drive object is established on the hardware driver layer according to respective bus type and/or pin information in the at least two first instructions. In this way, at least two vehicle diagnostic devices 20 are accessed to access the vehicle control network 30 for the vehicle diagnostic device 20 to access at least two ECUs.

其中，主线程可以在交通工具通信接口VCI10上电初始化时建立。主线程负责接收交通工具诊断设备20下发的数据(例如第一指令或者诊断指令)，并将数据分发给线程。可选的，主线程还可以负责接收线程发送的数据(例如交通工具的反馈数据)，并将数据上传给交通工具诊断设备20。The main thread can be established when the vehicle communication interface VCI10 is powered on. The main thread is responsible for receiving data (eg, first instructions or diagnostic instructions) issued by the vehicle diagnostic device 20 and distributing the data to the threads. Optionally, the main thread may also be responsible for receiving data sent by the thread (eg, feedback data of the vehicle) and uploading the data to the vehicle diagnostic device 20.

线程作为上述逻辑通道的管理者，用于管理一个ECU与所述交通工具诊断设备20的数据交互。即接收主线程发送的数据并将所述数据分发给协议对象，以及接收协议对象发送的数据并将所述数据发送给主线程或交通工具诊断设备20。可选的，线程创建时可以为其分配通道ID，以区分其他线程，使其被使用时只负责一个ECU的数据传输。The thread acts as a manager of the logical channel described above for managing data interaction between an ECU and the vehicle diagnostic device 20. That is, the data transmitted by the main thread is received and distributed to the protocol object, and the data transmitted by the protocol object is received and sent to the main thread or vehicle diagnostic device 20. Optionally, the thread ID can be assigned to the thread when it is created to distinguish other threads from being used by only one ECU for data transmission.

协议对象用于上层协议数据和物理层标准传输数据之间的转换。因为数据需要通过总线传输给交通工具控制网络30，所以数据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。在交通工具控制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，数据可以转换成CAN总线数据协议格式、K总线数据协议格式等。The protocol object is used for conversion between upper layer protocol data and physical layer standard transmission data. Since the data needs to be transmitted over the bus to the vehicle control network 30, the data needs to be converted to the physical layer's bus transmission data protocol format, i.e., data link layer and physical layer protocol conversion. When the vehicle control network includes a Controller Area Network (CAN) bus, a communication (Kommunikation, K) bus, etc., the data can be converted into a CAN bus data protocol format, a K bus data protocol format, and the like.

总线驱动对象用于接收协议对象发送的物理层标准传输数据并将所述数据通过总线发送给交通工具控制网络30，以及接收总线传输的物理层标准传输数据并将所述数据发送给协议对象。可以一个逻辑通道对应一个总线驱动对象，也可以多个逻辑通道共享同一总线驱动对象，前提是该逻辑通道对应的第一指令中的总线类型和管脚信息均相同，例如协议类型、总线类型、总线管脚数量和总线管脚编号相同。The bus driver object is configured to receive physical layer standard transmission data transmitted by the protocol object and transmit the data to the vehicle control network 30 via the bus, and receive physical layer standard transmission data of the bus transmission and transmit the data to the protocol object. One logical channel may correspond to one bus driving object, or multiple logical channels may share the same bus driving object, provided that the bus type and pin information in the first instruction corresponding to the logical channel are the same, for example, protocol type, bus type, The number of bus pins is the same as the bus pin number.

即如果所述至少2个第一指令中存在总线类型和管脚信息均相同的第一指令，则可以在所述硬件驱动层为总线类型和管脚信息均相同的第一指令共同建立一个总线驱动对象，为其他总线类型或管脚信息不相同的第一指令各自建立1个总线驱动对象。如果所述至少2个第一指令中各个第一指令的总线类型均不相同，或者各个第一指令的管脚信息均不相同，则在所述硬件驱动层分别为每个第一指令建立一个总线驱动对象。That is, if there is a first instruction in which the bus type and the pin information are the same in the at least two first instructions, a bus may be jointly established in the hardware driver layer for the first instruction in which the bus type and the pin information are the same. The drive object establishes one bus drive object for each of the first instructions having different bus types or pin information. If the bus types of the first instructions in the at least two first instructions are different, or the pin information of each first instruction is different, then each hardware driver layer establishes one for each first instruction. Bus driven object.

如图4所示，线程和协议对象通过抽象层的总线驱动对象与交通工具控制网络30中的ECU建立了逻辑关系，从而形成了多条交通工具诊断设备20访问交通工具控制网络30的逻辑通道，可以利用这些逻辑通道，同时访问多个ECU。As shown in FIG. 4, the thread and protocol objects establish a logical relationship with the ECUs in the vehicle control network 30 through the bus driver objects of the abstraction layer, thereby forming a logical channel for the plurality of vehicle diagnostic devices 20 to access the vehicle control network 30. You can use these logical channels to access multiple ECUs simultaneously.

本发明实施例通过根据至少两个第一指令建立至少两个用于传输交通工具诊断设备与ECU之间数据的逻辑通道，以此形成多条访问各个ECU的通道。通过该至少两个逻辑通道，交通工具诊断设备可以同时访问至少两个ECU，提高了诊断效率。Embodiments of the present invention form a plurality of channels for accessing individual ECUs by establishing at least two logical channels for transmitting data between the vehicle diagnostic device and the ECU in accordance with at least two first instructions. Through the at least two logical channels, the vehicle diagnostic device can simultaneously access at least two ECUs, improving diagnostic efficiency.

其中，交通工具诊断设备20通过交通工具通信接口VCI10给交通工具控制网络30发送第二指令(诊断指令)时，如图5所示，交通工具通信接口VCI10执行以下步骤：Wherein, when the vehicle diagnostic device 20 sends a second command (diagnostic command) to the vehicle control network 30 through the vehicle communication interface VCI10, as shown in FIG. 5, the vehicle communication interface VCI10 performs the following steps:

103：接收所述交通工具诊断设备20发送的至少2个第二指令，所述第二指令包括数据以及通道标识。103: Receive at least two second instructions sent by the vehicle diagnostic device 20, the second instructions including data and a channel identifier.

其中，所述第二指令可以为交通工具诊断设备20对交通工具控制网络30的诊断指令，包括指令本身和通道ID。在图2所示的实施例中，可以通过主线程接收该第二指令。The second instruction may be a diagnostic instruction of the vehicle diagnostic device 20 to the vehicle control network 30, including the instruction itself and the channel ID. In the embodiment shown in FIG. 2, the second instruction can be received by the main thread.

104：根据所述至少2个第二指令中各自的通道标识，确定至少2个逻辑通道，所述第二指令与所述逻辑通道一一对应。104: Determine, according to respective channel identifiers of the at least two second instructions, at least two logical channels, where the second instruction corresponds to the logical channel one-to-one.

105：通过所述至少2个逻辑通道，将所述至少2个第二指令中的数据发送至所述至少2个逻辑通道各自对应的ECU。105: Send, by the at least two logical channels, data in the at least two second instructions to an ECU corresponding to each of the at least two logical channels.

即根据第二指令中的通道标识，确定该第二指令对应的逻辑通道，并通过确定的逻辑通道将第二指令中的数据发送给对应的ECU。在图2所示的实施例 中，主线程根据通道标识确定该逻辑通道对应的线程，并将数据发送给线程，线程接收数据后再发送给对应的协议对象。协议对象将所述数据转换成对应的标准传输数据，并将所述标准传输数据发送给对应的总线驱动对象。总线驱动对象接收所述协议对象发送的标准传输数据，并将所述标准传输数据通过总线传送给交通工具控制网络30。That is, according to the channel identifier in the second instruction, the logical channel corresponding to the second instruction is determined, and the data in the second instruction is sent to the corresponding ECU through the determined logical channel. In the embodiment shown in FIG. 2, the main thread determines the thread corresponding to the logical channel according to the channel identifier, and sends the data to the thread, and the thread receives the data and then sends the data to the corresponding protocol object. The protocol object converts the data into corresponding standard transmission data and transmits the standard transmission data to a corresponding bus drive object. The bus driver object receives the standard transmission data transmitted by the protocol object and transmits the standard transmission data to the vehicle control network 30 via the bus.

当一个总线驱动对象被多个协议对象共享时，总线驱动对象将各个协议对象发送的标准传输数据缓冲到内存，然后以总线的当前吞吐量顺序的发送出去。When a bus driver object is shared by multiple protocol objects, the bus driver object buffers the standard transmission data sent by each protocol object into memory and then sends it out in the order of the current throughput of the bus.

交通工具诊断设备20通过交通工具通信接口VCI10接收交通工具控制网络30发送的反馈数据时，如图6所示，交通工具通信接口VCI10执行以下步骤：When the vehicle diagnostic device 20 receives the feedback data transmitted by the vehicle control network 30 via the vehicle communication interface VCI 10, as shown in FIG. 6, the vehicle communication interface VCI 10 performs the following steps:

106：接收至少2个ECU各自发送的数据。106: Receive data sent by at least two ECUs.

107：通过至少2个逻辑通道，将所述数据发送至所述交通工具诊断设备；其中，所述ECU与所述逻辑通道一一对应。107: Send the data to the vehicle diagnostic device through at least 2 logical channels; wherein the ECU is in one-to-one correspondence with the logical channel.

即接收各个ECU的反馈数据，并通过各个逻辑通道将反馈数据发送给交通工具诊断设备20,每个逻辑通道只负责传送与其自身对应的反馈数据。以图2所示的实施例为例，总线驱动对象实时检测总线上传输的数据，并将数据收集起来，过滤掉不相关的数据，获得反馈数据对应的标准传输数据，然后将该标准传输数据发送给该总线驱动对象对应的各个协议对象。每个协议对象会确认总线驱动对象发送的反馈数据对应的标准传输数据是否是自身负责的ECU对应的反馈数据，如果是，会接收该反馈数据对应的标准传输数据，如果否，协议对象不会接收该反馈数据对应的标准传输数据。协议对象接收到所述标准传输数据后，对该数据进行协议转换，获得反馈数据，然后将该反馈数据发送给其对应的线程。线程接收到其负责的ECU对应的反馈数据，可以直接将该反馈数据发送给交通工具诊断设备20，也可以通过主线程将反馈数据发送给交通工具诊断设备20。That is, the feedback data of each ECU is received, and the feedback data is sent to the vehicle diagnostic device 20 through each logical channel, and each logical channel is only responsible for transmitting feedback data corresponding to itself. Taking the embodiment shown in FIG. 2 as an example, the bus driving object detects the data transmitted on the bus in real time, collects the data, filters out irrelevant data, obtains standard transmission data corresponding to the feedback data, and then transmits the standard data. Send to each protocol object corresponding to the bus driver object. Each protocol object confirms whether the standard transmission data corresponding to the feedback data sent by the bus drive object is the feedback data corresponding to the ECU that is responsible for itself, and if so, receives the standard transmission data corresponding to the feedback data, and if not, the protocol object does not Receiving standard transmission data corresponding to the feedback data. After receiving the standard transmission data, the protocol object performs protocol conversion on the data, obtains feedback data, and then sends the feedback data to its corresponding thread. The thread receives the feedback data corresponding to the ECU that it is responsible for, and may directly send the feedback data to the vehicle diagnostic device 20, or may send the feedback data to the vehicle diagnostic device 20 through the main thread.
