[0049] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0050] The following is an illustrative introduction to the vehicle gateway routing test method, device, equipment and storage medium provided in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application.

[0051] First, an in-vehicle gateway routing test system provided in an embodiment of the present application is introduced. Figure 1 A schematic diagram of the structure of a vehicle gateway routing test system provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the system includes: a host computer, a vehicle gateway routing test device and a vehicle gateway. The vehicle gateway routing test device is connected to the host computer and the vehicle gateway, and the vehicle gateway routing test device and the vehicle gateway can communicate through channel 1 and channel 2. The vehicle gateway routing test device can obtain data from the host computer and receive instructions sent by the host computer.

[0052] It should be noted that the host computer refers to a computer device that can directly issue control commands, usually a personal computer (PC) or a host computer (Master Computer). The display interface of the host computer is an important window for users to interact with the system. Through the graphical interface, users can easily monitor the operating status of the system, obtain key data, and even remotely control the system. In addition, the host computer software also has functions such as data processing, storage, alarm and report generation, providing users with a comprehensive system management and monitoring experience.

[0053] It should be noted that the vehicle gateway is a device used for communication and data transmission between the vehicle and the external network. It acts as a bridge between the vehicle's internal system and the external network, allowing the vehicle to interact with the cloud platform, mobile devices and other vehicles.

[0054] It should be noted that the vehicle gateway routing test device can be connected to multiple vehicle gateways to implement vehicle gateway routing tests on multiple different vehicle gateways.

[0055] Figure 2 One of the flow charts of a vehicle gateway routing test method provided in an embodiment of the present application is applied to Figure 1 The vehicle gateway routing test device in the vehicle gateway routing test system shown in FIG. Figure 2 As shown, the method includes:

[0056] S201. Upon receiving a vehicle gateway routing test instruction sent by the host computer, determine a target vehicle gateway routing test item corresponding to a target vehicle control function indicated by the vehicle gateway routing test instruction; the target vehicle gateway routing test item includes a test instance of performing a vehicle gateway routing test on a target vehicle gateway related to the target vehicle control function.

[0057] It should be noted that a test instance, which can also be understood as a test case, is a test scenario designed for a specific purpose. It can include input data, expected output, and execution conditions. In the vehicle gateway routing test, the test instance is used to verify whether the routing function of the gateway meets the design requirements, including signal routing and message routing.

[0058] In some embodiments, the vehicle gateway routing test items corresponding to the vehicle gateways respectively related to different vehicle control functions can be first obtained, and then when the vehicle gateway routing test instructions sent by the host computer are received, the target vehicle gateway routing test items corresponding to the target vehicle control function indicated by the vehicle gateway routing test instructions sent by the host computer can be determined from the vehicle gateway routing test items corresponding to the vehicle gateways respectively related to different vehicle control functions.

[0059] It can be understood that, since the target vehicle gateway routing test item includes a test instance of performing a vehicle gateway routing test on a target vehicle gateway related to a target vehicle control function, the target vehicle gateway routing test item can be used to perform a vehicle gateway routing test on the target vehicle gateway.

[0060] In some embodiments, the vehicle gateway routing test instruction sent by the host computer may instruct to test at least one vehicle control function of the vehicle controller group to be tested.

[0061] In some embodiments, the vehicle gateway routing test instruction may be triggered by a user through a vehicle gateway routing test button preset on a display screen of a host computer, and may be an instruction sent by the host computer to a vehicle gateway routing test device.

[0062] It should be noted that if the vehicle controller group to be tested has a vehicle control function, then in the vehicle gateway routing test scenario, the vehicle gateway routing test device receives only one type of vehicle gateway routing test instruction, namely, an instruction to test the vehicle control function.

[0063] It should be noted that the vehicle-mounted gateway routing test method provided in the embodiment of the present application involves all gateway routing test channels. Figure 3 A schematic diagram of gateway routing test channel classification provided in an embodiment of the present application, such as Figure 3 As shown, it includes: proximal CAN diagnostic access (OBD DCAN), proximal Ethernet diagnostic access (OBD Diag Ethernet), remote diagnosis (TBOX) and OTA diagnosis (TBOX). Among them, proximal CAN diagnostic access refers to the vehicle diagnosis performed by accessing the vehicle's data communication area network (DCAN) through the vehicle's on-board diagnostics (OBD) interface; proximal Ethernet diagnostic access is a vehicle diagnosis performed through the vehicle's OBD interface using Ethernet technology; remote diagnosis is vehicle diagnosis based on the on-board information service terminal (Telematics BOX, TBOX); Over-the-Air (OTA) diagnosis is the remote software update and diagnosis of the vehicle based on TBOX.

[0064] It should be noted that each channel in the gateway routing test channel classification has routing data of multiple signal types, such as Figures 4 to 7As shown. Among them, the diagnostic instrument DoCAN directly diagnoses BDC2.0, which means using the diagnostic instrument to diagnose BDC2.0 (a specific automotive control system or module) directly through the Diagnostic over Controller Area Network (DoCAN) protocol; Diagnostic over Internet Protocol (DoIP) is a diagnostic method based on the IP protocol, and DoCAN is a diagnosis based on the CAN protocol. DoCAN-DoIP means that the diagnostic process involves both CAN and IP protocols, usually through a gateway or bridge device to achieve communication between the CAN network and the IP network; DoCAN-DoCANFD means that the DoCAN protocol is used for communication, but the data link layer uses the CAN technology CANFD (CAN with Flexible Data-Rate) with a variable data rate, and DLC64 refers to the maximum length code (Data Length Code) of the data frame. Code, DLC) is 64, which means that more data can be transmitted; DoCAN-DoCAN refers to a diagnostic method that uses the DoCAN protocol to communicate directly between different CAN nodes; DoIP-DoIP (Layer 2 forwarding) refers to a diagnostic communication method that forwards DoIP packets at the data link layer (the second layer of the OSI model); Car-Cloud DoIP Direct Diagnosis BDC2.0 refers to the use of DoIP diagnostic technology to achieve direct and real-time diagnosis of BDC2.0 by diagnostic equipment through communication between the vehicle and the cloud server; DoIP-DoIP (application layer forwarding) refers to a diagnostic communication method that forwards DoIP packets at the application layer; DoIP-DoCANFD (DLC=64) means using the DoIP protocol for diagnostic communication, combined with the high data rate and large data load capacity of CANFD technology.

[0065] S202: Based on the target vehicle gateway routing test item, perform a vehicle gateway routing test on the target vehicle gateway to obtain a vehicle gateway routing test result.

[0066] In an embodiment of the present application, after receiving the vehicle gateway routing test instruction sent by the host computer, the vehicle gateway routing test instruction can be responded to, and based on the target vehicle gateway routing test item corresponding to the target vehicle control function indicated by the vehicle gateway routing test instruction, a vehicle gateway routing test can be performed on the target vehicle gateway related to the target vehicle control function, thereby realizing targeted gateway routing automation testing.

[0067] It should be noted that the vehicle gateway routing test is an evaluation of the performance of the vehicle gateway device in terms of network communication, data forwarding, and protocol conversion. After the vehicle gateway routing test is performed, the vehicle gateway routing test results obtained include but are not limited to network connectivity test results, data transmission integrity test results, data transmission delay test results, and data transmission bandwidth test results.

[0068] It can be understood that the vehicle gateway routing test method provided in the embodiment of the present application determines the target vehicle gateway routing test item corresponding to the target vehicle control function indicated by the vehicle gateway routing test instruction when receiving the vehicle gateway routing test instruction sent by the host computer, wherein the target vehicle gateway routing test item includes a test instance of performing a vehicle gateway routing test on the target vehicle gateway related to the target vehicle control function, and then based on the target vehicle gateway routing test item, the target vehicle gateway is subjected to a vehicle gateway routing test to obtain a vehicle gateway routing test result. In this way, an automated gateway routing test based on software simulation and targeted vehicle gateway routing test items is realized, which greatly reduces the dependence on real ECU hardware and the testing workload, improves the pertinence and execution efficiency of the vehicle gateway routing test, and realizes the dynamic selection of the vehicle gateway routing test item through the vehicle gateway routing test instruction sent by the host computer, thereby enhancing the versatility of the vehicle gateway routing test.

[0069] In some embodiments, the vehicle gateway routing test method further includes:

[0070] Obtaining vehicle gateway routing test setting parameters from the host computer;

[0071] Based on the vehicle gateway routing test setting parameters, generating at least one vehicle gateway routing test item;

[0072] The step of determining, upon receiving the vehicle gateway routing test instruction sent by the host computer, a target vehicle gateway routing test item corresponding to the target vehicle control function indicated by the vehicle gateway routing test instruction comprises:

[0073] When the vehicle gateway routing test instruction sent by the host computer is received, the target vehicle gateway routing test item corresponding to the target vehicle control function indicated by the vehicle gateway routing test instruction is determined from the at least one vehicle gateway routing test item.

[0074] It should be noted that the vehicle gateway routing test setting parameters may include: construction parameters of the vehicle gateway routing test environment and setting parameters of the vehicle gateway routing test items.

[0075] In some embodiments, the construction parameters of the vehicle gateway routing test environment include: configuration parameters, variable definition parameters and timing setting parameters. Among them, the configuration parameters represent the environment configuration file of the vehicle gateway routing test environment.

[0076] In some embodiments, a configuration file represented by configuration parameters can be loaded according to the configuration parameters. The configuration file includes: channel port setting rules and address information of each vehicle controller in the gateway to be tested, such as: physically addressed send identifier (Transaction ID, TxID) information, physically addressed receive identifier (Receive ID, RxID) information, physically addressed TxID information related to OBD data, physically addressed RxID information related to OBD data, logical address information, Tester address information (network address of the device used for simulation or testing in vehicle network testing), Tester vehicle cloud address information (network address of the device used for simulation or testing when the vehicle-mounted device communicates with the cloud server), Tester OTA address information (network address of the device used for simulation or testing during OTA update process).

[0077] In some embodiments, global variables can be defined according to variable definition parameters. The defined global variables include: response time variables, address type variables, status flag variables, data type variables, data length variables, and data name variables. The response time variable refers to the response time of the gateway after receiving the vehicle gateway routing test request, for example: less than 1 second; the address type variable refers to the address type of the gateway receiving the vehicle gateway routing test request, for example: physical address and functional address, different types of vehicle controller addresses, corresponding to the gateway control forwarding routing signal function range is different; the status flag variable is a variable that characterizes the state of the vehicle controller, for example: before receiving the next vehicle gateway routing test request, it is necessary to determine that the state of the vehicle controller is the original state, that is, the state flag is the state flag corresponding to the original state; the data type variable refers to the type of data transmitted, for example: the data corresponding to the vehicle gateway routing test request and the vehicle gateway routing test request response data; the data length variable refers to the variable corresponding to the length requirement of the data of each data type; the data name variable refers to the variable corresponding to the name of each data.

[0078] In some embodiments, the test timing of each vehicle gateway routing test item of the vehicle gateway routing test scenario can be set according to the timing setting parameters to complete the construction of the vehicle gateway routing test environment corresponding to the vehicle gateway routing test scenario according to the vehicle gateway routing test environment construction parameters. Among them, the test timing data represents the test timing of each vehicle gateway routing test item. If the vehicle gateway routing test scenario includes multiple vehicle gateway routing test items, and the vehicle control function of the vehicle controller group to be tested corresponding to each vehicle gateway routing test item has a timing requirement, then the vehicle gateway routing test item corresponding to the vehicle control function also needs to have certain timing requirements, and the test timing of the vehicle gateway routing test item corresponds to the test timing of the vehicle control function corresponding to the vehicle gateway routing test item.

[0079] It should be noted that in a vehicle gateway routing test scenario, the vehicle controller group to be tested corresponds to at least one vehicle control function, and one vehicle control function corresponds to one vehicle gateway routing test item.

[0080] In some embodiments, after generating at least one vehicle gateway routing test item of the vehicle gateway routing test scenario based on the vehicle gateway routing test setting parameters obtained from the host computer, a vehicle gateway routing test can be performed on the target vehicle gateway related to the vehicle control function indicated by the vehicle gateway routing test instruction in response to the vehicle gateway routing test instruction, based on the target vehicle gateway routing test item corresponding to the target vehicle control function indicated by the vehicle gateway routing test instruction.

[0081] It is understandable that the vehicle gateway routing test may involve multiple communication protocols, different message types (such as direct messages, periodic messages, etc.) and complex network topologies. The embodiment of the present application automatically generates vehicle gateway routing test items by obtaining preset vehicle gateway routing test setting parameters from the host computer, which can flexibly support complex vehicle gateway routing test scenarios.

[0082] In some embodiments, the target vehicle gateway routing test item further includes a request generation condition; the request generation condition is used to characterize a generation condition of the vehicle gateway routing test request;

[0083] The performing a vehicle gateway routing test on the target vehicle gateway based on the target vehicle gateway routing test item to obtain a vehicle gateway routing test result includes:

[0084] Generate a vehicle gateway routing test request based on the request generation condition in the target vehicle gateway routing test item;

[0085] Sending the vehicle gateway routing test request to the target vehicle gateway, and obtaining the vehicle gateway routing test response data fed back by the target vehicle gateway after processing the vehicle gateway routing test request;

[0086] Based on the in-vehicle gateway routing test response data, the in-vehicle gateway routing test result is obtained.

[0087] It should be noted that the vehicle gateway routing test items include: request generation conditions, the request generation conditions represent the generation conditions of the vehicle gateway routing test request, and the vehicle gateway routing test request is used to indicate the acquisition of data.

[0088] In some embodiments, the vehicle gateway routing test instruction indicates to test at least one vehicle control function of the vehicle controller group to be tested. Therefore, the vehicle gateway routing test item corresponding to the vehicle control function indicated by the vehicle gateway routing test instruction, that is, at least one vehicle gateway routing test item, can be determined according to the at least one vehicle control function indicated by the vehicle gateway routing test instruction, and then according to the request generation condition in each determined vehicle gateway routing test item, a vehicle gateway routing test request corresponding to each determined vehicle gateway routing test item is generated, and the generated vehicle gateway routing test request is sent to the corresponding vehicle gateway, and the vehicle gateway routing test response data fed back by the corresponding vehicle gateway is obtained. Among them, the data obtained by the vehicle gateway routing self-test request corresponds to the corresponding vehicle gateway routing test item, and also corresponds to the vehicle control function of the vehicle controller corresponding to the vehicle gateway routing test item.

[0089] In some embodiments, after receiving the vehicle gateway routing test response data, the vehicle gateway routing test response data can be analyzed according to the target vehicle gateway routing test item corresponding to the vehicle control function indicated by the vehicle gateway routing test instruction to obtain the vehicle gateway routing test result.

[0090] In some embodiments, the vehicle gateway routing test response data may include multiple data types such as CAN data, CANFD data, and Ethernet data.

[0091] It can be understood that the embodiment of the present application generates a vehicle gateway routing test request based on the request generation conditions in the specific vehicle gateway routing test item, so as to ensure that the vehicle gateway routing test is targeted at a specific routing function or scenario, which helps to accurately verify whether the routing performance of a specific vehicle gateway meets expectations.

[0092] In some embodiments, the target vehicle gateway routing test item further includes a vehicle gateway routing test parsing condition;

[0093] The obtaining the vehicle gateway routing test result based on the vehicle gateway routing test response data includes:

[0094] Based on the vehicle gateway routing test parsing condition in the target vehicle gateway routing test item, the vehicle gateway routing test response data is filtered to obtain filtered vehicle gateway routing test response data;

[0095] Based on the filtered in-vehicle gateway routing test response data, the in-vehicle gateway routing test result is obtained.

[0096] It should be noted that the vehicle gateway routing test item also includes a vehicle gateway routing test parsing condition, which is used to filter the vehicle gateway routing test response data to filter out the vehicle gateway routing test response data that is directly related to the test purpose and valid.

[0097] In an embodiment of the present application, after receiving the vehicle gateway routing test response data fed back by the target vehicle gateway, the vehicle gateway routing test response data fed back by the target vehicle gateway can be screened based on the vehicle gateway routing test parsing condition in the target vehicle gateway routing test item to obtain the screened vehicle gateway routing test response data, and then based on the screened vehicle gateway routing test response data, the vehicle gateway routing test result is obtained. In this way, by screening the vehicle gateway routing test response data, data that is not directly related to the test purpose or is invalid can be removed, ensuring that the analyzed data is accurate and useful, which helps to improve the accuracy of the vehicle gateway routing test results, so that the vehicle gateway routing test can more truly reflect the routing performance of the vehicle gateway.

[0098] In some embodiments, the target vehicle gateway routing test item further includes a vehicle gateway routing test verification condition;

[0099] The obtaining the vehicle gateway routing test result based on the filtered vehicle gateway routing test response data includes:

[0100] Based on the vehicle gateway routing test verification condition in the target vehicle gateway routing test item, the filtered vehicle gateway routing test response data is verified to obtain the vehicle gateway routing test result.

[0101] It should be noted that the vehicle gateway routing test item also includes a vehicle gateway routing test verification condition, which is used to verify the vehicle gateway routing test response data to obtain the verification result of the vehicle gateway routing test response data as the vehicle gateway routing test result.

[0102] In an embodiment of the present application, after receiving the vehicle gateway routing test response data fed back by the target vehicle gateway, the vehicle gateway routing test response data fed back by the target vehicle gateway can be screened based on the vehicle gateway routing test parsing condition in the target vehicle gateway routing test item to obtain the screened vehicle gateway routing test response data, and then based on the vehicle gateway routing test verification condition in the target vehicle gateway routing test item, the screened vehicle gateway routing test response data is verified, and the verification result of the vehicle gateway routing test response data is obtained as the vehicle gateway routing test result. In this way, by verifying the filtered vehicle gateway routing test response data, the accuracy of the filtered vehicle gateway routing test response data can be verified, including the format, range and logical consistency of the data, thereby further improving the accuracy of the vehicle gateway routing test result.

[0103] In some embodiments, the vehicle gateway routing test method further includes:

[0104] Based on the vehicle gateway routing test result, a vehicle gateway routing test report is generated.

[0105] In an embodiment of the present application, after obtaining the vehicle gateway routing test result, a vehicle gateway routing test report can be generated based on the vehicle gateway routing test result. The vehicle gateway routing test report can clearly and intuitively display the vehicle gateway routing test result in the form of text and charts, including the performance of various test indicators, whether the expected standards are met, etc., so that users can quickly understand the vehicle gateway routing test result and grasp the overall performance of the vehicle gateway routing function.

[0106] In some embodiments, the vehicle gateway routing test method further includes:

[0107] The vehicle gateway routing test result is sent to the host computer so that the host computer can display the vehicle gateway routing test result through a display interface.

[0108] In an embodiment of the present application, after obtaining the vehicle gateway routing test result, the vehicle gateway routing test result can be sent to a host computer so that the host computer can display the vehicle gateway routing test result through a display interface, so that the user can intuitively read the vehicle gateway routing test result.

[0109] It should be noted that the host computer can display the vehicle gateway routing test result in the form of text or charts through the display interface. The embodiment of the present application does not specifically limit the display method of the vehicle gateway routing test result.

[0110] In some embodiments, after obtaining the vehicle gateway routing test response data, a matching check can be performed on the function items and display items of the vehicle controller group to be tested, and the matching check result can be used as the vehicle gateway routing test result, and then the vehicle gateway routing test report is automatically generated and sent to the tester's mailbox for verification; at the same time, after obtaining the vehicle gateway routing test result, the vehicle gateway routing test result can be sent to the host computer to be presented to the user through the display interface of the host computer, so that the user can intuitively read the vehicle gateway routing test result.
