[0041] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. In addition, the technical features in the various embodiments or single embodiments provided by the present invention can be arbitrarily combined with each other to form a feasible technical solution. This combination is not restricted by the sequence of steps and / or structural composition mode, but must be based on the ability of ordinary technicians in this field to implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0042] To address the low efficiency and quality assurance issues of manual inspections of existing in-vehicle Ethernet services, the present invention proposes a method that can analyze complex Ethernet messages through a Python program and then combine it with an Ethernet service inspection form template to significantly improve inspection efficiency and ensure inspection quality.

[0043] Figure 1 The present invention provides a flow chart of an automatic inspection method for vehicle Ethernet services, such as Figure 1 As shown, the automatic inspection method mainly includes the following steps:

[0044] S1, recording Ethernet messages that need to be inspected based on CANoe software.

[0045] It is understandable that for Ethernet messages that need to be inspected, CANoe software is used to record the Ethernet messages that need to be inspected, and the records are exported and saved in an asc format file.

[0046] S2, parsing the Ethernet message based on the Python program, and storing the parsed Ethernet message into a corresponding two-dimensional data table according to the message type.

[0047] As an embodiment, the message types include Offer Service, Subscribe and EventNotification; the Python program is used to parse the Ethernet message, and the parsed Ethernet message is stored as a corresponding two-dimensional data table according to the message type, including: storing the Ethernet message in different two-dimensional data tables according to different message types, and the two-dimensional data table includes a timestamp field and a service information field.

[0048] As you can understand, a Python program is written to parse the Ethernet message file generated above and store the parsed messages into different two-dimensional data tables based on message type. In other words, different two-dimensional data tables store different types of Ethernet messages. Depending on inspection requirements, message types that need to be stored include Offer Service, Subscribe, and EventNotification. In addition to basic fields like timestamp and Service ID (service information), the data in the two-dimensional data tables also contains attributes specific to each message type.

[0049] S3, based on Python program, parses the Ethernet service template table and extracts all service information that needs to be checked.

[0050] As an embodiment, an Ethernet service template table is compiled based on the service table of the in-vehicle Ethernet. The Ethernet service template table includes service information of all services that need to be inspected and expected results of each inspection item of each service.

[0051] The method of parsing the Ethernet service template table based on a Python program and extracting service information of all services requiring inspection includes: parsing the Ethernet service template table based on a Python program and extracting all service information therein and the expected result of each inspection item of each service.

[0052] It is understandable that an Ethernet service template table is pre-established, and the Ethernet service template table includes service information (service unique identification ID) of all services that need to be inspected and the expected result of each inspection item of each service.

[0053] When the Ethernet service needs to be inspected subsequently, service information of all services that need to be inspected and the expected result of each inspection item of each service are extracted from the Ethernet service template table.

[0054] S4, based on the service information of any service that needs to be inspected, the inspection items corresponding to the current service are checked in the two-dimensional data table to obtain the inspection result of each inspection item.

[0055] As an embodiment, the service information of any service that needs to be inspected checks the inspection items corresponding to the current service in the two-dimensional data table to obtain the inspection results of each inspection item, including: finding the corresponding type of two-dimensional data table based on the inspection type of any service that needs to be inspected; finding all corresponding inspection items in the corresponding two-dimensional data table based on the service information of any service that needs to be inspected; analyzing the Ethernet message of each inspection item to obtain the analysis result; comparing the analysis result of each inspection item with the corresponding expected result, if they are consistent, the inspection result is successful; if they are inconsistent, the inspection result is failed.

[0056] If the inspection type is inspection service delivery, obtain a two-dimensional data table of Offer Service type; check the period of Offer Service messages in the two-dimensional data table of Offer Service type and whether the Socket information of each message is correct to obtain an analysis result.

[0057] It is understandable that according to the extracted service information and the expected results of the inspection items, the corresponding two-dimensional data table is analyzed. For example, if the service delivery needs to be inspected, the Offer Service two-dimensional table is analyzed to check the cycle of the Offer Service message and whether the Socket information of each message is correct.

[0058] S5, writing the inspection result into the Ethernet service template table, wherein the inspection result corresponds to the service information.

[0059] As an embodiment, the step of writing the inspection result into the Ethernet service template table, wherein the inspection result corresponds to the service information, includes: writing the inspection result into the Ethernet service template table, and indicating the abnormal reason for a failed inspection result.

[0060] See also Figure 2 The following is a flowchart of the automatic inspection method for in-vehicle Ethernet services provided by the present invention. First, Ethernet messages requiring inspection are recorded using CANoe and exported as ASC files. The Ethernet messages are then parsed and stored in different two-dimensional data tables according to message type. The Ethernet service template table is then parsed to extract service information for all services requiring inspection and the expected results for each inspection item for each service. The extracted service information and expected results for each inspection item are stored in a service queue.

[0061] When performing a spot check on a service, the service that needs to be inspected (the service to be inspected) and the expected results of each spot check item of the service are taken out from the service queue. According to the spot check type of the service to be inspected, the corresponding two-dimensional data table is found. According to the service information of the service to be inspected, all spot check items for the service are found from the two-dimensional data table. The Ethernet message of each spot check item is analyzed to obtain the analysis result. The analysis result of each spot check item is compared with the expected result to obtain the spot check result. Finally, the obtained spot check result is written into the Ethernet service template table.
