Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a hybrid networking protocol design method, apparatus, electronic device, and storage medium. Background Technology

[0002] Currently, more and more vehicle manufacturers are adopting a software-defined vehicle strategy, promoting the separation and decoupling of software and hardware, and the proportion of self-developed software is gradually increasing. International and domestic manufacturers have generally carried out pre-research or mass production of Service Oriented Architecture (SOA).

[0003] The biggest challenge of SOA architecture for in-vehicle communication is the need to send service-oriented software interface data via the bus so that the receiving software module can directly read it from the bus. For services requiring end-to-end security protection, E2E (end-to-end) serialization is used to add E2E header verification. Because SOA network architecture includes not only advanced Ethernet control nodes but also nodes that are not suitable for Ethernet but are better suited for CAN (Controller Area Network) buses, such as nodes that have been developed using the CAN protocol and have high conversion costs, service-to-signal conversion is required to transmit service-oriented data to nodes that do not support SOME / IP (Scalable service-Oriented Middleware over IP) service-oriented communication. This conversion is performed by the application module.

[0004] Due to the capacity difference between Ethernet and CAN communication, this conversion is inefficient. After the service is converted into a signal, it needs to be converted back into software interface data by software, increasing the software load. The conversion between service and signal will disrupt the security protection of the entire link. Ethernet and CAN protocols cannot be matched one-to-one. Service data is usually classified according to functional domains, such as chassis data, comfort data, and infotainment data. CAN data can only be divided into units based on controller nodes, which cannot be precisely matched in terms of design logic. The service-to-signal conversion of the Ethernet-CAN protocol and the signal-to-signal conversion of the CAN-CAN protocol are performed simultaneously, resulting in high bandwidth consumption. Summary of the Invention

[0025] Example 1

[0026] Figure 1 This is a flowchart of a hybrid networking protocol design method according to Embodiment 1 of the present invention. This embodiment is applicable to the transmission of service data and message data. The method can be executed by a hybrid networking protocol design device, which can be implemented in hardware and / or software and can be configured in an electronic device. Figure 1 As shown, the method includes:

[0027] S110. Obtain the data to be sent based on the sending end; wherein, the data to be sent includes at least one of service data and message data.

[0028] The sending end can refer to the device's application software or control node. For example, the sending end can be the control node in an SOA network architecture.

[0029] In this embodiment, the data to be sent may include service data and message data. Service data refers to SOA service-oriented data; message data refers to CAN communication signal data.

[0030] In this scheme, the sending end can send the data to be sent to the receiving end through SOME / IP service-based communication, or it can send the data to be sent to the receiving end through the CAN bus.

[0031] S120. The data to be sent is constructed according to the data structure of the hybrid networking protocol to obtain target data, and the target data is sent to the receiving end; wherein, the data structure includes data type, data tag and packet data.

[0032] The receiving end can refer to the device's application software or control node. For example, the receiving end can be the control node of a CAN bus.

[0033] In this scheme, the hybrid networking protocol is used to characterize the hybrid networking protocol of CANXL and SOME / IP based on E2E functional safety protection. This protocol is implemented based on the CANXL physical layer and can support data transmission of up to 1400 bytes, enabling the transmission of large amounts of data. CANXL is a highly scalable communication technology.

[0034] In this embodiment, the protocol design allows SOA service-oriented data and CAN communication signal data to be arranged in parallel within the data field of the CANXL message. This addresses issues such as the efficiency of sending service-oriented data to CAN nodes, link security and consistency, data transmission methods divided by functional domains, and concurrent service-to-signal and signal-to-signal routing. It effectively improves the compatibility of the SOA architecture with the CAN network, the feasibility of sending service-oriented data to CAN nodes, and the security and consistency of the communication link. This also reduces the development cost of CAN controller transformation, increases the coverage of the SOA architecture, and supports the implementation of the software-defined vehicle strategy.

[0035] Specifically, the data to be sent is constructed according to the data structure of the hybrid networking protocol, and the constructed target data can be sent to the receiving end through the CANXL physical layer.

[0036] Optionally, the data types include service data and message data; used to characterize the type of each packet data in the hybrid networking protocol frame content.

[0037] In this scheme, the data type field specifies the data types of each group in the protocol frame content, including service data and message data, and may also include request data. The length of the data type field can be configured in detail according to the data type.

[0038] By constructing the data to be sent according to the data structure of the hybrid networking protocol, the compatibility between SOA architecture and CAN network, the feasibility of sending service-oriented data to CAN nodes, and the security and consistency of communication links can be effectively improved, reducing the development cost of CAN controller transformation and increasing the coverage of SOA architecture.

[0039] Optionally, the method further includes:

[0040] The data types of the data to be sent are divided according to preset functional domains; wherein, the functional domains are divided according to vehicle functions.

[0041] In this embodiment, the functional domains may include chassis, intelligent driving, entertainment, etc., and can be divided according to the data type of the vehicle functions to be sent in a specific scenario. For example, the functional domain of the data to be sent may be intelligent driving.

[0042] By dividing the data to be sent according to functional domains, the problem of data transmission based on functional domain division can be solved.

[0043] Optionally, the method further includes:

[0044] The data types of the data to be sent are categorized according to preset communication types.

[0045] Specifically, based on communication type, service data can be divided into request-response services, notification services, data distribution services, and request-without-response services, etc.; and message data can be divided into application periodic messages, diagnostic request messages, and diagnostic response messages, etc.

[0046] By classifying the data to be sent according to the communication type, the problem of data transmission based on communication type can be solved.

[0047] Optionally, the data tag includes the grouped data type, identification number, grouped data length, and grouped data security verification number;

[0048] The identification number is used to represent the unique identifier for the receiving end to identify the packet data; the packet data security verification number is used to represent the number used by the receiving end to perform security verification.

[0049] In this embodiment, the data tag field specifies the data tag for each packet of data in this protocol frame, including the packet data type, identification number, packet data length, and packet data security check number.

[0050] Among them, the packet data type refers to whether the packet data is service-type or message-type; the identification number refers to the unique identifier that can be used by the receiving application software or control node to identify the packet data; the packet data length refers to the length value of this packet data, which the receiving end can extract and parse based on the length value; the packet data security check number refers to the number used by the receiving application software or control node to perform security verification on this packet data, and the receiving end uses a predefined security encryption protocol to verify the data based on the security check number.

[0051] By constructing the data to be sent according to the data structure of the hybrid networking protocol, the compatibility between SOA architecture and CAN network, the feasibility of sending service-oriented data to CAN nodes, and the security and consistency of communication links can be effectively improved, reducing the development cost of CAN controller transformation and increasing the coverage of SOA architecture.

[0052] Optionally, the packet data includes checksum data, public key data, and application data;

[0053] The checksum data is used to characterize the data verified by the receiving end.

[0054] In this embodiment, application data can refer to service data content and message data content.

[0055] In this scheme, the packet data field contains either service data content or message data content, and is the part that actually carries the communication data. Service data and message data can coexist in the packet data, which can be identified through the data tags and packet data types mentioned above.

[0056] Furthermore, the packet data includes checksum data, public key data, and application data to provide a deeper level of end-to-end security.

[0057] The checksum data refers to the data used for verification by the receiving end. For example, the receiving end can verify the target data using the same verification method and compare the verification result with the checksum data to determine whether the verification result matches the checksum data. The public key data is used by the receiving end to decrypt the target data.

[0058] In this scheme, each segment of the target data can be independently encrypted, decrypted, and verified for security. The transmission process of the message does not involve the conversion of services and signals, so it will not destroy end-to-end security information.

[0059] By constructing the data to be sent according to the data structure of the hybrid networking protocol, the compatibility between SOA architecture and CAN network, the feasibility of sending service-oriented data to CAN nodes, and the security and consistency of communication links can be effectively improved, reducing the development cost of CAN controller transformation and increasing the coverage of SOA architecture.

[0060] Optionally, after obtaining the target data, the method further includes:

[0061] The target data is arranged in parallel in the data field of the controller local area network bus.

[0062] In this scheme, service data and message data can be placed in the same communication frame in parallel.

[0063] Specifically, service data and message data can be arranged in parallel in the data field of the CANXL message, and grouped according to functional domains. Each group of data can be named {Functional Domain 1_Service Data 1_Security Protection Data}, {Functional Domain 2_Message Data 2_Non-Security Protection Data}, etc.

[0064] By arranging target data in parallel in the data field of the controller area network bus, it is possible to solve problems such as the efficiency of sending service-oriented data to CAN nodes and link security and consistency. This can effectively improve the compatibility of SOA architecture and CAN network, the feasibility of sending service-oriented data to CAN nodes, and the security and consistency of communication links, reduce the development cost of CAN controller transformation, improve the coverage of SOA architecture, and support the implementation of software-defined vehicle strategy.

[0065] For example, in an in-vehicle network system, there are three Ethernet nodes: the front IVI (In-Vehicle Infotainment), the AR-HUD (Head-Up Display), and the front microphone; one CAN node for the headlights; and four CANXL hybrid network nodes for the front / left cameras and the front / left ultrasonic systems. The camera system needs to send text prompts to the front IVI, send traffic flow prompt projection icons to the AR-HUD, and send headlight height adjustment commands to the headlight system via messages, based on road conditions and traffic flow information. In this scenario, the hybrid network message data labels are set as services and messages. Packet data 1 is the text prompt service, and label 1 is service sequence number 1 (e.g., 0x45038001); packet data 2 is the projection icon display service, and label 2 is service sequence number 2 (e.g., 0x7A039002); packet data 3 is the headlight adjustment message, and label 3 is message sequence number 3 (0x20103).

[0066] The technical solution of this invention obtains the data to be sent from the sending end, constructs the data according to the data structure of a hybrid networking protocol to obtain target data, and sends the target data to the receiving end. The data structure includes data type, data tag, and packet data. By implementing this technical solution, the efficiency of sending service data to controller LAN nodes, link security and consistency, data transmission methods, and data concurrency conversion routing issues can be resolved. This effectively improves the feasibility of transmitting service data and message data, increases the transmission efficiency of service data and message data, and ensures the security and consistency of the communication link.
