[0045] To make the objectives, technical solutions, and advantages of the present application clearer, the technical solutions in the present application will be clearly and completely described below with reference to the accompanying drawings in the present application. Apparently, the described embodiments are some, rather than all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without making creative efforts shall fall within the protection scope of the present application.
[0046] An embodiment of the present application provides a routing table generation method, and the execution subject thereof may be an electronic device. For example, it may be a controller. The following takes the execution subject of this method being a controller as an example for description. Figure 1 It is a schematic flowchart of the routing table generation method provided by an embodiment of the present application. Refer to Figure 1 , this method may include:
[0047] Step 110: Verify the accuracy of each piece of information in the controller area network matrix table based on a preset rule to obtain a verification result; the controller area network matrix table includes communication matrix node (English: Matrix node) information, and the communication matrix node information includes the controller area network message name and signal description of the communication matrix node. The suffix of the controller area network message name is the local interconnect network message identifier to be converted, and the signal description includes the local interconnect network segment to which the local interconnect network message identifier belongs. The local interconnect network segment is included in the name of the target local interconnect network matrix file;
[0048] Step 120: If the verification result is successful verification, establish a target routing table for the conversion between the controller area network protocol and the local interconnect network protocol based on the controller area network matrix table and the target local interconnect network matrix file.
[0049] In step 110, the controller may establish a vehicle model controller area network matrix table, which may include communication matrix node information. The communication matrix node information may include the controller area network message name and signal description of the communication matrix node. The purpose of creating the controller area network matrix master table is to better maintain the sending and receiving relationships of messages and signals between each network segment and each node of the vehicle model. In particular, the suffix of the controller area network message name is the local interconnect network message identifier to be converted, and the local interconnect network message identifier is determined based on the predefined mapping relationship between the controller area network and the local interconnect network identifiers. The signal description may include the local interconnect network segment to which the local interconnect network message identifier belongs, and the local interconnect network segment is included in the name of the target local interconnect network matrix file, so as to associate the mutually convertible controller area network and local interconnect network protocols, and then extract the message controller area network and local interconnect network links. It should be noted that if the controller area network message needs to be routed to multiple local interconnect networks, the corresponding local interconnect network segment names are added to the signal description column of the message row, separated by " / ".
[0050] The controller may verify the accuracy of each piece of information in the controller area network matrix table based on a preset rule to obtain a verification result. Specifically, the accuracy of the controller area network matrix table may be judged by verifying the correspondence between the local interconnect network messages and the controller area network messages involved in the controller area network matrix table.
[0051] In step 120, if the accuracy verification of each piece of information in the controller area network matrix table is successful, the controller may establish a target routing table for the conversion between the controller area network protocol and the local interconnect network protocol based on the controller area network matrix table and the target local interconnect network matrix file. Specifically, according to the conversion requirement (controller area network to local interconnect network or local interconnect network to controller area network), the source network segment information and the target network segment information may be respectively extracted from the controller area network matrix table and the target local interconnect network matrix file to form a target routing table.
[0052] The routing table generation method provided by the embodiments of the present application can intelligently generate a target routing table by establishing a controller area network matrix table related to the local interconnect network matrix file, and based on the controller area network matrix table and the target local interconnect network matrix file when verifying the accuracy of each piece of information in the controller area network matrix table, which is convenient for the gateway node to make routing strategies and improves the fluency and reliability of cross-network communication.

The gateway node information includes all controller names. The network segment information to which the communication matrix node belongs is the network segment to which all communication matrix nodes belong. In addition to the communication matrix node page, the CAN matrix table creates "routing list" and "vehicle model information list" pages, as shown in the following table:

[0064] When the controller verifies the accuracy of each piece of information in the controller area network matrix table based on a preset rule, it can verify whether the controller area network message name carries the _0x suffix and whether the suffix is ≤ 0x3F (the identifier range of the local interconnect network protocol), verify whether the transceiver relationship corresponding to the controller area network message identifier involves the target gateway node, the target gateway node has cross-network communication capabilities and is included in the gateway node information, verify whether there is a local interconnect network message identifier in the target local interconnect network matrix file, so as to judge the correctness of the target local interconnect network matrix file, and verify whether the transceiver relationship of the target gateway node is consistent, so as to ensure the smooth progress of cross-network communication. When all the above verifications pass, the verification result is verification success.
[0065] The routing table generation method provided by the embodiments of the present application can ensure the accuracy of the generation of the target routing table by verifying the accuracy of each piece of information in the controller area network matrix table and generating the target routing table when the verification is successful, which is convenient for the gateway node to make routing policies and improves the fluency and reliability of cross-network communication.
[0066] In some embodiments, the communication matrix node information further includes the controller area network message length and the controller area network message period; if the transceiver relationship of the target gateway node is sending, based on the controller area network matrix table and the target local interconnect network matrix file, a target routing table for converting the controller area network protocol and the local interconnect network protocol is established, including: determining the target network segment to which the target gateway node belongs based on the network segment information to which the communication matrix node belongs; taking the controller area network message identifier, the controller area network message length, the controller area network message period, the target network segment, and the receiving node of the target network segment as the target network segment information of the target routing table; obtaining the local interconnect network message length and the local interconnect network message period corresponding to the local interconnect network message identifier from the target local interconnect network matrix file; taking the local interconnect network message identifier, the local interconnect network message length, the local interconnect network message period, the local interconnect network segment, and the sending node of the local interconnect network segment as the source network segment information of the target routing table.

[0068] The target routing table is shown in the following table:

Fill in the gateway node in the Target / Source-Domain controler column of the target routing table.
[0071] When the transceiver relationship of the target gateway node is reception, do the same as above, except that the source network segment and the target network segment are swapped.
[0072] The routing table generation method provided by the embodiments of the present application can intelligently generate a target routing table by establishing a Controller Area Network (CAN) matrix table related to a local interconnected network matrix file, and based on the CAN matrix table and the target local interconnected network matrix file when verifying that the information in the CAN matrix table is accurate, to establish a target routing table for the conversion between the CAN protocol and the local interconnected network protocol.

For example, the controller can check whether the CAN message length in the target routing table is consistent with the local interconnected network message length, and whether the CAN message period is consistent with the local interconnected network message period. Only when both are consistent can cross-network communication be achieved.
[0078] The routing table generation method provided by the embodiments of the present application establishes a Controller Area Network (CAN) matrix table related to the local interconnected network matrix file.
