[0034] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0035] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0036] First, it's important to clarify that automotive Ethernet can be a local area network connecting the vehicle's electronic units. Data transmission via Ethernet enables various vehicle services, such as opening windows, turning on headlights, activating the audio system, or other services. Automotive Ethernet messages can include various types of data exchanged and transmitted over Ethernet; among these, vehicle service data is essential supporting data for research in vehicle communication.

[0037] In practical processing of vehicular Ethernet packets, the large volume of packet data makes it difficult for manual analysis to accurately and quickly extract service data from the packets. The vehicular Ethernet packet identification system of this invention converts each service interface parameter in the vehicular Ethernet service list into signal name data and further generates a communication matrix for all signals. Then, based on each service interface parameter, the packet parameters corresponding to each signal in the Ethernet service packet can be extracted. Finally, by assigning the packet parameters to each signal in the communication matrix, the target service data can be generated, thereby achieving rapid and accurate identification of service data within the Ethernet packet.

[0038] Please see Figure 1 As shown, Figure 1This is a block diagram illustrating an exemplary embodiment of an in-vehicle Ethernet packet identification system. This system can be applied to in-vehicle Ethernet data identification, and can also be applied to other implementation environments. This embodiment does not limit the implementation environment to which the system is applicable. This exemplary in-vehicle Ethernet packet identification system may include a signal name generation module 110, a matrix generation module 120, a packet parsing module 130, and a data generation module 140. Specifically, the signal name generation module 110 can convert each service interface parameter in the in-vehicle Ethernet service list into signal name data. The matrix generation module 120 can further generate a communication matrix for all signals based on the signal name data and signal attribute data. The packet parsing module 130 can extract the packet parameters corresponding to each signal in the Ethernet service packet based on each service interface parameter. The data generation module 140 can assign the packet parameters to each signal in the communication matrix to generate target service data.

[0039] In one embodiment of the present invention, the signal name generation module 110 can perform data conversion on each service interface parameter of the vehicle Ethernet service list to generate signal name data for the signal corresponding to each service interface parameter. Specifically, the vehicle Ethernet service list may include multiple service interface information. The signal name generation module 110 can read the service interface information in the vehicle Ethernet service list and convert the service interface parameters in each service interface information into signal name data for CAN signals. The conversion process of converting service interface parameters into signal name data for CAN signals can first involve the signal name generation module 110 reading "Service", "HashId", "ServiceInterfaceName", "InputParameterName", "InputParameterDataTypeName", "InputParameterDataType", or other parameter data from the vehicle Ethernet service list. Next, the signal name generation module 110 can read pre-set data structure table information, which may include various data names. Based on the data names in the data structure table and the parameter names read above, the signal name generation module 110 can convert the read service interface parameters into signal name data.

[0040] In one embodiment of the present invention, when the signal data generation module 110 performs data conversion on each service interface parameter of the vehicle Ethernet service list, it may perform data conversion based on preset data conversion rules. These data conversion rules include ordinary parameter conversion rules, structure parameter conversion rules, array parameter conversion rules, and structure array parameter conversion rules. Specifically, when the service interface parameter to be converted is an ordinary type parameter, the signal name data converted based on the data name in the data structure table and the parameter name read above can be represented as "service name" + "_" + "method name" + "_" + "parameter name". When the service interface parameter to be converted is a structure parameter, the signal name data converted based on the data name in the data structure table and the parameter name read above can be represented as "service name" + "_" + "method name" + "structure name" + "_" + "member name". When the service interface parameter to be converted is an array parameter, the signal name data after conversion based on the data name in the data table structure and the parameter name read above can be represented as service name "+ "_" + "method name" + "_" + "parameter name" + "_ number". When the service interface parameter to be converted is a structure array parameter, the signal name data after conversion based on the data name in the data table structure and the parameter name read above can be represented as a combination of service name "+ "_" + "method name" + "structure name" + "_" + "member name" and service name "+ "_" + "method name" + "_" + "parameter name" + "_ number".

[0041] In one embodiment of the present invention, the matrix generation module 120 can process the signal name data and signal attribute data of all signals to generate a communication matrix for all signals. Specifically, the matrix generation module 120 can perform data association processing on the signal name data and signal attribute data of all the signals to generate the communication matrix, wherein the signal attribute data may include signal length data, signal start bit data, and signal identifier. Further, the matrix generation module 120 can calculate the signal length data corresponding to each signal name data, calculate the signal start bit data of each signal using the signal length data, and then generate a corresponding CanId (signal identifier) ​​for each signal. Finally, the matrix generation module 120 can perform association processing on the signal name data, signal length data, signal start bit data, and signal identifier to generate a CAN communication matrix based on the rules of the CAN communication matrix.

[0042] In one embodiment of the present invention, the message parsing module 130 can extract parameters from the vehicle Ethernet service message based on each of the service interface parameters to obtain the message parameters corresponding to each signal. Specifically, the message parsing module 130 can extract valid data corresponding to the parameter identification information of the vehicle Ethernet service list from the serialized data of the vehicle Ethernet service message to generate the message parameters corresponding to each signal. The above-mentioned message parameter extraction process can be specifically described as follows: first, extract the submessageId (sub-message identifier) ​​from the Ethernet service message information from the xxx.pcapng format file, and further extract the serializedData (serialized data) from the submessageId (sub-message identifier), determine whether there is data in the serializedData (serialized data) that is the same as the HashId (parameter identification information), and if there is data that is the same, then extract the valid data after the HashId (parameter identification information) in the serializedData (serialized data) to generate the message parameters.

[0043] In one embodiment of the present invention, the data generation module 140 can assign data values ​​to each signal in the communication matrix based on the message parameters corresponding to each signal to generate target service data. Specifically, the target service data can be an .asc file. The data generation module 140 can extract the signal name data, signal length data, and signal start bit data from the CAN communication matrix into the .asc file, and assign the message parameters to the corresponding positions of each signal to generate the .asc file.

[0044] Please see Figure 1 As shown, in one embodiment of the present invention, the vehicle Ethernet packet identification system may further include a service data filtering module 150. The service data filtering module 150 can filter data from the vehicle Ethernet service form 160 based on service attributes to generate a vehicle Ethernet service list. The service attributes may include service type, service domain, and service scope. Specifically, the vehicle Ethernet service form 160 includes multiple service interface information. Multiple service interface information can be filtered based on service attributes to select the desired vehicle Ethernet service list. Further, the service type in the service attributes can represent the type of each service interface, such as turning on headlights, opening windows, or other service types. The service domain can represent the domain to which each service interface belongs, such as the chassis domain, powertrain domain, or other domains. The service scope can represent the service scope of each service interface, such as within the chassis domain, outside the chassis domain, or other scopes. By setting filtering restrictions for service type, service domain, and service scope, the desired vehicle Ethernet service list can be filtered out. It should be noted that service attributes can also be other attributes, which are not limited here.

[0045] Please see Figure 1 As shown, in one embodiment of the present invention, when the above-mentioned vehicle Ethernet message identification system actually generates the CAN matrix, the user can place the "Vehicle Ethernet Service Form.xlsx" file and the captured vehicle Ethernet service message "xxx.pcapng" file in the same directory structure as the "Ethernet Service Log Parsing Tool.exe" file corresponding to the parsing tool 170, and then run the exe program. Next, the service interface information and data structure table information in the "Vehicle Ethernet Service Form.xlsx" are read into the system. The service data filtering module 150 can filter the "Vehicle Ethernet Service Form.xlsx" to filter out the list of vehicle Ethernet services that need to be converted. Then, the signal name generation module 110 polls and reads the information of each service interface in the vehicle Ethernet service list, and converts the service interface parameters of each service interface into the signal name of the corresponding signal. The matrix generation module 120 can calculate signal length data, signal start position data, and generate signal attribute data such as signal identifiers. After all polling reads are completed, the matrix generation module 120 can associate the signal name data, signal length data, signal start bit data, and signal identifier to generate a communication matrix for all signals. It should be noted that the communication matrix can be analyzed and visualized using a bus analysis tool 190, such as CANoe, improving data analysis efficiency.

[0046] Please see Figure 1 As shown, in one embodiment of the present invention, when the above-mentioned vehicle Ethernet packet recognition system actually generates the target service data of the .asc file, the user can place the "Vehicle Ethernet Service Form.xlsx" file, the captured vehicle Ethernet service packet "xxx.pcapng" file, and the "Ethernet Service Log Parsing Tool.exe" file in the same directory structure, and then run the exe program. The signal information in the communication matrix is ​​read into the system, and then the Ethernet service packet file 180 in the "xxx.pcapng" file is read into the system. The packet parsing module 130 can poll and parse each Ethernet service packet file. If a certain Ethernet service packet file contains data with the same HashId (parameter identification information), the packet parameters corresponding to the signal in each Ethernet service packet information are extracted, and the packet parameters are assigned to the corresponding position of the signal. After all polling and parsing is completed, the target service data of the .asc file is generated. It should be noted that the target service data of the .asc file can be analyzed and visualized based on a bus analysis tool 190, such as the CANoe tool, to improve data analysis efficiency.

[0047] Please see Figure 2As shown, this invention provides a method for identifying vehicle Ethernet packets, which can be applied to the identification of vehicle Ethernet packets to improve identification efficiency and accuracy. The method for identifying vehicle Ethernet packets may include the following steps:

[0048] Step S210: The signal name generation module performs data conversion on each service interface parameter of the vehicle Ethernet service list to generate signal name data for each service interface parameter.

[0049] Step S220: The signal name data and signal attribute data of all the signals are processed by the matrix generation module to generate a communication matrix for all the signals.

[0050] Step S230: The message parsing module extracts parameters from the vehicle Ethernet service message based on the parameters of each service interface to obtain the message parameters corresponding to each signal.

[0051] Step S240: The data generation module assigns data values ​​to each signal in the communication matrix based on the message parameters corresponding to each signal to generate target service data.

[0052] In one embodiment of the present invention, when step S210 is executed, the signal data generation module performs data conversion on each service interface parameter of the vehicle Ethernet service list to generate signal name data corresponding to each service interface parameter. Specifically, the vehicle Ethernet service list may include multiple service interface information. The signal name generation module 110 can read the service interface information in the vehicle Ethernet service list and convert the service interface parameters in each service interface information into signal name data of the CAN signal. The process of converting service interface parameters into signal name data for CAN signals can begin by having the signal name generation module 110 read "Service", "HashId", "ServiceInterfaceName", "InputParameterName", "InputParameterDataTypeName", "InputParameterDataType", or other parameter data from the vehicle Ethernet service list. Next, the signal name generation module 110 can read pre-set data structure table information, which may include various data names. Based on the data names in the data structure table and the parameter names read above, the signal name generation module 110 can convert the read service interface parameters into signal name data.

[0053] It should be further noted that when the signal name generation module 110 performs data conversion on each service interface parameter of the vehicle Ethernet service list, it can do so based on preset data conversion rules. These data conversion rules include ordinary parameter conversion rules, structure parameter conversion rules, array parameter conversion rules, and structure array parameter conversion rules. Specifically, when the service interface parameter to be converted is an ordinary type parameter, the signal name data after conversion based on the data name in the data structure table and the parameter name read above can be represented as "service name" + "_" + "method name" + "_" + "parameter name". When the service interface parameter to be converted is a structure parameter, the data after conversion based on the data name in the data structure table and the parameter name read above can be represented as "service name" + "_" + "method name" + "structure name" + "_" + "member name". When the service interface parameter to be converted is an array parameter, the signal name data after conversion based on the data name in the data table structure and the parameter name read above can be represented as service name "+ "_" + "method name" + "_" + "parameter name" + "_ number". When the service interface parameter to be converted is a structure array parameter, the signal name data after conversion based on the data name in the data table structure and the parameter name read above can be represented as a combination of service name "+ "_" + "method name" + "structure name" + "_" + "member name" and service name "+ "_" + "method name" + "_" + "parameter name" + "_ number".

[0054] In one embodiment of the present invention, before executing step S210, i.e., before the signal data generation module performs data conversion on each service interface parameter of the vehicle Ethernet service list to generate signal name data corresponding to each service interface parameter, the method further includes filtering the vehicle Ethernet service form based on service attributes by a service data filtering module to generate the vehicle Ethernet service list. The service attributes include service type, service domain, and service scope. Specifically, service attributes may include service type, service domain, and service scope. Specifically, the vehicle Ethernet service form includes multiple service interface information, and multiple service interface information can be filtered based on service attributes to select the desired vehicle Ethernet service form. Further, the service type in the service attributes can represent the type of each service interface, such as turning on headlights, opening windows, or other service types. The service domain can represent the domain to which each service interface belongs, such as the chassis domain, powertrain domain, or other domains. The service scope can represent the service scope of each service interface, such as within the chassis domain, outside the chassis domain, or other scopes. By setting filtering criteria such as service type, service domain, and service scope, you can filter out the desired list of in-vehicle Ethernet services.

[0055] In one embodiment of the present invention, when step S220 is executed, the matrix generation module processes the signal name data and signal attribute data of all the signals to generate a communication matrix for all the signals. Specifically, the matrix generation module 120 can perform data association processing on the signal name data and signal attribute data of all the signals to generate the communication matrix. The signal attribute data may include signal length data, signal start bit data, and signal identifier. Further, the matrix generation module 120 can calculate the signal length data corresponding to each signal name data, and calculate the signal start bit data for each signal using the signal length data. Finally, the matrix generation module 120 can perform association processing on the signal name data, signal length data, signal start bit data, and signal identifier to generate a CAN communication matrix based on the rules of the CAN communication matrix.

[0056] Please see Figure 3 As shown, in one embodiment of the present invention, the above-mentioned vehicle Ethernet packet identification system may include the following steps when actually generating the CAN matrix:

[0057] Step S310: The user places the "Vehicle Ethernet Service Form.xlsx" file, the captured vehicle Ethernet service packet "xxx.pcapng" file, and the "Ethernet Service Log Parsing Tool.exe" file corresponding to the parsing tool 170 in the same directory structure, and then runs the exe program. Next, the service interface information and data structure table information from the "Vehicle Ethernet Service Form.xlsx" file are read into the program.

[0058] Step S320: Filter the “Vehicle Ethernet Service Form.xlsx” file through the service data filtering module 150 to filter out the list of vehicle Ethernet services that need to be converted.

[0059] Step S330: The signal name generation module 110 polls and reads the information of each service interface in the vehicle Ethernet service list, and converts the service interface parameters of each service interface into the signal name of the corresponding signal.

[0060] Step S340: The matrix generation module 120 calculates signal length data, signal start position data, and generates signal attribute data such as signal identifier.

[0061] Step S350: After all polling reads are completed, the matrix generation module 120 can associate the signal name data, signal length data, signal start bit data, and signal identifier to generate a communication matrix for all signals.

[0062] In one embodiment of the present invention, when step S230 is executed, the message parsing module extracts parameters from the vehicle Ethernet service message based on each of the service interface parameters to obtain the message parameters corresponding to each signal. It should be noted that the message parsing module 130 can extract valid data corresponding to the parameter identification information of the vehicle Ethernet service list from the serialized data of the vehicle Ethernet service message to generate the message parameters corresponding to each signal. The above-mentioned message parameter extraction process can be specifically described as follows: first, extracting the submessageId (sub-message identifier) ​​from the Ethernet service message information in the xxx.pcapng format file; further, extracting the serializedData (serialized data) from the submessageId (sub-message identifier); determining whether there is data in the serializedData (serialized data) that is the same as the HashId (parameter identification information); if there is the same data, then extracting the valid data after the HashId (parameter identification information) in the serializedData (serialized data) to generate the message parameters.

[0063] In one embodiment of the present invention, when step S240 is executed, data values ​​are assigned to each signal in the communication matrix based on the message parameters corresponding to each signal to generate target service data. Specifically, the target service data can be an .asc file. The data generation module 140 can extract the signal name data, signal length data, and signal start bit data from the CAN communication matrix into an .asc file, and assign the message parameters to the corresponding positions of each signal to generate the .asc file.

[0064] Please see Figure 4 As shown, in one embodiment of the present invention, the above-mentioned vehicle Ethernet packet recognition system may include the following steps when actually generating the target service data of the ASC file:

[0065] Step S410: The user places the "Vehicle Ethernet Service Form.xlsx" file, the captured vehicle Ethernet service message "xxx.pcapng" file, and the "Ethernet Service Log Parsing Tool.exe" file in the same directory structure, then runs the exe program to read the signal information in the communication matrix into its internal structure, and then reads the Ethernet service message file 180 in the "xxx.pcapng" file into its internal structure.

[0066] Step S420: The message parsing module 130 polls and parses each Ethernet service message file. If there is data with the same HashId (parameter identification information) in a certain Ethernet service message file, the message parameter corresponding to the signal in each Ethernet service message information is extracted and the message parameter is assigned to the corresponding position of the signal.

[0067] Step S430: After all polling and parsing is completed, the target service data in the asc file is generated.

[0068] As can be seen, in the above scheme, the service interface parameters in the vehicular Ethernet service list are converted into a communication matrix, and the message parameters corresponding to each signal in the Ethernet service message are extracted based on the service interface parameters. Finally, the message parameters are assigned to each signal in the communication matrix to generate the target service data, thereby achieving fast and accurate identification of service data in the Ethernet message.

[0069] It should be noted that the vehicle Ethernet packet recognition system and the vehicle Ethernet packet recognition method provided in the above embodiments belong to the same concept.
