Description

Technical Field

[0001] This invention relates to the field of automotive technology, and in particular to a gateway testing method, system, computer, and readable storage medium. Background Technology

[0002] With the steady development of the automotive industry, automobiles have become an important tool in production and daily life, leading to a continuous increase in car ownership. As the number of cars increases, their configurations also become more diverse. These diverse configurations require the simultaneous matching of multiple CAN (Controller Area Network) segments. The effectiveness and accuracy of signal interaction between these segments directly reflect the quality of the vehicle's features and the customer experience.

[0003] As a routing component in the entire vehicle, the gateway plays a crucial role in the development of vehicle functions. Therefore, strict requirements are placed on the completeness and reliability of gateway functions. However, current technologies limit gateway function testing to checking each message after vehicle assembly or on a vehicle test bench. This testing method is not only labor-intensive and tedious, but also prone to missing functions. Furthermore, the amount of data generated during testing is enormous, making it impossible to achieve complete and effective testing of the gateway component. Summary of the Invention

[0004] Based on this, the purpose of this invention is to provide a gateway testing method, system, computer, and readable storage medium to solve the problem that the existing technology for testing gateway functions is limited to checking each message information after the vehicle is installed or on the vehicle test bench. This testing method is not only labor-intensive and cumbersome, but also prone to missing functions. At the same time, the amount of data generated by the test is huge, which makes it impossible to perform complete and effective testing of gateway components.

[0005] The first aspect of this invention provides a gateway testing method, the method comprising:

[0006] Receive a DBC file input by the user and generate corresponding gateway routing information based on the DBC file. The gateway routing information includes the various functional modules of the gateway.

[0007] The module parameters corresponding to each of the functional modules are detected in the preset database, and several test cases corresponding to each of the module parameters are generated. Each test case is unique.

[0008] A communication connection with the vehicle's CAN bus is established through VSPY, and a CAN path corresponding to the CAN bus is simulated through VSPY.

[0009] Several test cases are transmitted to the vehicle's gateway via the CAN channel, and the vehicle's signal environment is simulated via VSPY, so that the gateway can be tested in the signal environment using the test cases.

[0010] The beneficial effects of this invention are as follows: By receiving a DBC file input by the user and generating corresponding gateway routing information based on the DBC file, the gateway routing information includes various functional modules of the gateway; further, by detecting module parameters corresponding to each functional module in a preset database and generating several test cases corresponding to each module parameter, each test case being unique; further still, by establishing a communication connection with the vehicle's CAN bus through VSPY and simulating a CAN path corresponding to the CAN bus through VSPY; finally, by transmitting several test cases to the vehicle's gateway through the CAN path and simulating the vehicle's signal environment through VSPY, the gateway can be tested in the signal environment using the test cases. This method enables the generation of corresponding test cases in real time based on the module parameters of each functional module in the vehicle gateway, and simultaneously simulates a test environment adapted to the current vehicle gateway, thereby enabling simultaneous testing of multiple functional modules in the vehicle gateway. This significantly reduces the testing workload and prevents the omission of untested functional modules, making it suitable for widespread promotion and use.

[0017] Generate the corresponding test cases based on each of the aforementioned test metrics.

[0018] Preferably, the step of serializing each module parameter using a first preset algorithm to generate several corresponding test sequences includes:

[0019] When several module parameters are obtained, the structured parameters and unstructured parameters contained in each module parameter are identified by a preset ARX model, and both the structured parameters and the unstructured parameters are stored in a preset MySQL relational database.

[0020] In the preset MySQL relational database, the structured parameters are serialized and the unstructured parameters are filtered using the first preset algorithm to generate several test sequences.

[0021] Preferably, after the step of simulating the vehicle's signal environment using VSPY to complete the test of the gateway in the signal environment through the test cases, the method further includes:

[0022] Receive the test results output by VSPY in real time, and determine whether the test results are within a preset threshold;

[0023] If the test result is determined to be within the preset threshold, the gateway of the current vehicle is determined to meet the factory requirements, and a corresponding test tag is generated based on the test result.

[0024] If the test result is determined to be outside the preset threshold, the gateway of the current vehicle is determined to be non-compliant with the factory requirements, and the gateway of the current vehicle is retested.

[0025] A second aspect of this invention provides a gateway testing system, the system comprising:

[0029] The testing module is used to transmit several test cases to the vehicle's gateway through the CAN channel, and to simulate the vehicle's signal environment through the VSPY, so as to complete the testing of the gateway through the test cases in the signal environment.

[0049] The following detailed description, in conjunction with the accompanying drawings, will further illustrate the present invention. Detailed Implementation

[0050] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of the invention are illustrated in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0051] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0052] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0053] As a routing component in the entire vehicle, the gateway plays a crucial role in the development of vehicle functions. Therefore, strict requirements are placed on the completeness and reliability of gateway functions. However, current technologies limit gateway function testing to checking each message after the vehicle is installed or on a test bench. This testing method is not only labor-intensive and tedious, but also prone to missing functions. Furthermore, the amount of data generated during testing is enormous, making it impossible to achieve complete and effective testing of the gateway component.

[0054] Please see Figure 1 The diagram shows a gateway testing method provided in the first embodiment of the present invention. The gateway testing method provided in this embodiment can generate corresponding test cases in real time according to the module parameters of each functional module in the vehicle gateway. At the same time, it can also simulate a test environment adapted to the current vehicle gateway in real time, thereby completing the testing of multiple functional modules in the vehicle gateway at the same time, which greatly reduces the workload of testing and will not cause the phenomenon of missing functional modules. It is suitable for widespread promotion and use.

[0055] Specifically, the gateway testing method provided in this embodiment includes the following steps:

[0056] Step S10: Receive the DBC file input by the user and generate corresponding gateway routing information based on the DBC file. The gateway routing information includes the various functional modules of the gateway.

[0057] Specifically, in this embodiment, it should first be noted that the gateway testing method provided in this embodiment is specifically applied to the gateways of different vehicle models. It is used to detect in real time whether the gateway in the vehicle is qualified before the vehicle leaves the factory, so as to ensure the quality of the vehicle and improve the user's driving experience.

[0058] Therefore, in this embodiment, in order to accurately complete the test of the vehicle gateway, this embodiment will first receive the DBC (Dynamic Body Control) file input by the user in real time. The DBC file can simulate the working state of the vehicle gateway during the vehicle's driving process in real time.

[0059] Furthermore, this embodiment will generate corresponding gateway routing information based on the real-time received DBC file. Specifically, the gateway routing information received in this embodiment includes the various functional modules of the gateway in the current vehicle.

[0060] Step S20: Detect the module parameters corresponding to each of the functional modules in the preset database, and generate a number of test cases corresponding to each of the module parameters, each of the test cases being unique;

[0061] Furthermore, in this step, it should be noted that after obtaining the various functional modules corresponding to the current vehicle gateway through the above steps, this step will further detect the module parameters corresponding to each current functional module in the pre-set parameter database. At the same time, several test cases corresponding to each current module parameter will be generated. In this embodiment, each test case is unique and corresponds one-to-one with each functional module.

[0062] Step S30: Establish a communication connection with the vehicle's CAN bus through VSPY, and simulate the CAN path corresponding to the CAN bus through VSPY.

[0063] Furthermore, in this embodiment, it should be noted that after generating the required test cases through the above steps, this step further establishes a communication connection with the CAN bus in the current vehicle using a pre-configured VSPY tool. Based on this, the VSPY tool is used to simulate the CAN path corresponding to the CAN bus of the current vehicle in real time. It should be noted that the VSPY provided in this embodiment is a tool that integrates network monitoring, data acquisition / recording, node simulation, diagnostics, and automatic testing functions, enabling effective testing of vehicle gateways.

[0064] Step S40: Transmit several test cases to the vehicle's gateway through the CAN channel, and simulate the vehicle's signal environment through VSPY, so as to complete the test of the gateway through the test cases in the signal environment.

[0065] Finally, it should be noted in this step that after obtaining the required CAN path and test cases through the above steps, this step will further transmit the current test cases to the current vehicle's gateway through the current CAN path. On this basis, the VSPY tool mentioned above will be used to simulate the current vehicle's signal environment, i.e., the current vehicle's test environment, so that the gateway in the current vehicle can be tested in the current signal environment through the above test cases.

[0066] In use, the system receives a DBC file input by the user and generates corresponding gateway routing information based on the DBC file. This gateway routing information includes the various functional modules of the gateway. Further, it detects module parameters corresponding to each functional module in a preset database and generates several test cases corresponding to each module parameter, each test case being unique. Further still, it establishes a communication connection with the vehicle's CAN bus via VSPY and simulates a CAN path corresponding to the CAN bus using VSPY. Finally, it transmits the test cases to the vehicle's gateway via the CAN path and simulates the vehicle's signal environment using VSPY, allowing the gateway to be tested within that signal environment. This method enables real-time generation of corresponding test cases based on the module parameters of each functional module in the vehicle gateway. Simultaneously, it can simulate a test environment compatible with the current vehicle gateway, allowing for simultaneous testing of multiple functional modules within the vehicle gateway. This significantly reduces the testing workload and prevents the omission of untested functional modules, making it suitable for widespread adoption and use.

[0067] It should be noted that the above implementation process is only to illustrate the feasibility of this application, but it does not mean that the gateway testing method of this application has only the above-mentioned unique implementation process. On the contrary, as long as the gateway testing method of this application can be implemented, it can be included in the feasible implementation scheme of this application.

[0068] In summary, the gateway testing method provided by the above embodiments of the present invention can generate corresponding test cases in real time based on the module parameters of each functional module in the vehicle gateway. At the same time, it can also simulate a test environment adapted to the current vehicle gateway in real time, thereby enabling the simultaneous testing of multiple functional modules in the vehicle gateway. This significantly reduces the workload of testing and prevents the omission of untested functional modules, making it suitable for widespread promotion and use.

[0069] The second embodiment of the present invention also provides a gateway testing method. The gateway testing method provided in this embodiment differs from the gateway testing method provided in the first embodiment above in that:

[0070] Specifically, in this embodiment, it should be noted that the steps of detecting the module parameters corresponding to each of the functional modules in the preset database and generating several test cases corresponding to each of the module parameters include:

[0071] When each of the functional modules is obtained, the module type corresponding to each functional module is identified, and the module parameters corresponding to each functional module are detected in the preset database according to the module type.

[0072] Each module parameter is serialized using a first preset algorithm to generate several corresponding test sequences, each of which includes several test factors.

[0073] Several test cases are generated based on several test factors.

[0074] Specifically, in this embodiment, it should be noted that when this embodiment acquires various functional modules, such as Bluetooth, Wi-Fi, and media player modules, it immediately identifies the module type corresponding to each functional module. For example, the Bluetooth module corresponds to a transmission type module, and the media player corresponds to an entertainment type module. Based on this, this embodiment further detects the module parameters corresponding to each functional module in the aforementioned preset database according to the identified module type. For example, the transmission distance parameter and transmission frequency parameter corresponding to the Bluetooth module.

[0075] Furthermore, in this embodiment, the parameters of each module are serialized using a pre-set DTW algorithm to generate several required test sequences. Each test sequence includes several test factors. Further, several required test cases are generated based on the current test factors.

[0076] It should be noted that the method provided in the second embodiment of the present invention has the same implementation principle and some technical effects as the first embodiment. For the sake of brevity, any parts not mentioned in this embodiment can be referred to the corresponding content provided in the first embodiment.

[0077] In summary, the gateway testing method provided by the above embodiments of the present invention can generate corresponding test cases in real time based on the module parameters of each functional module in the vehicle gateway. At the same time, it can also simulate a test environment adapted to the current vehicle gateway in real time, thereby enabling the simultaneous testing of multiple functional modules in the vehicle gateway. This significantly reduces the workload of testing and prevents the omission of untested functional modules, making it suitable for widespread promotion and use.

[0078] The third embodiment of the present invention also provides a gateway testing method. The gateway testing method provided in this embodiment differs from the gateway testing method provided in the first embodiment above in that:

[0079] Furthermore, in this embodiment, it should be noted that the step of generating several test cases based on several test factors includes:

[0080] When several test factors are obtained, cluster analysis is performed on the several test factors respectively to generate several corresponding target test matrices, and test indicators corresponding to each module parameter are calculated based on the several target test matrices.

[0081] Generate the corresponding test cases based on each of the aforementioned test metrics.

[0082] Furthermore, in this embodiment, it should be noted that when this embodiment obtains several test factors, it will further perform cluster analysis on the current several test factors using the above-mentioned DTW algorithm to generate several corresponding target test matrices. It should be pointed out that each target test matrix includes several specific parameter values. Based on this, test indicators corresponding to each module parameter are calculated according to each target test matrix. Furthermore, corresponding test cases are generated according to each test indicator generated in real time.

[0083] It should be noted that the method provided in the third embodiment of the present invention has the same implementation principle and some technical effects as the first embodiment. For the sake of brevity, any parts not mentioned in this embodiment can be referred to the corresponding content provided in the first embodiment.

[0084] In summary, the gateway testing method provided by the above embodiments of the present invention can generate corresponding test cases in real time based on the module parameters of each functional module in the vehicle gateway. At the same time, it can also simulate a test environment adapted to the current vehicle gateway in real time, thereby enabling the simultaneous testing of multiple functional modules in the vehicle gateway. This significantly reduces the workload of testing and prevents the omission of untested functional modules, making it suitable for widespread promotion and use.

[0085] The fourth embodiment of the present invention also provides a gateway testing method. The gateway testing method provided in this embodiment differs from the gateway testing method provided in the first embodiment above in that:

[0086] Specifically, in this embodiment, it should also be noted that the step of serializing each module parameter using the first preset algorithm to generate several corresponding test sequences includes:

[0087] When several module parameters are obtained, the structured parameters and unstructured parameters contained in each module parameter are identified by a preset ARX model, and both the structured parameters and the unstructured parameters are stored in a preset MySQL relational database.

[0088] In the preset MySQL relational database, the structured parameters are serialized and the unstructured parameters are filtered using the first preset algorithm to generate several test sequences.

[0089] In this embodiment, it should be noted that when this embodiment obtains several required module parameters, it will further identify the structured parameters and unstructured parameters contained in each module parameter through a pre-set ARX model. Specifically, the structured parameters may include specific numerical values, and the corresponding unstructured parameters may include specific symbols and identifiers.

[0090] Furthermore, this embodiment will store both the identified structured and unstructured parameters in a preset MySQL relational database. Specifically, this embodiment will further serialize the current structured parameters in the current preset MySQL relational database using the aforementioned DTW algorithm, and correspondingly filter the current unstructured parameters to ultimately generate several required test sequences.

[0091] It should be noted that the method provided in the fourth embodiment of the present invention has the same implementation principle and some technical effects as the first embodiment. For the sake of brevity, any parts not mentioned in this embodiment can be referred to the corresponding content provided in the first embodiment.

[0092] In summary, the gateway testing method provided by the above embodiments of the present invention can generate corresponding test cases in real time based on the module parameters of each functional module in the vehicle gateway. At the same time, it can also simulate a test environment adapted to the current vehicle gateway in real time, thereby enabling the simultaneous testing of multiple functional modules in the vehicle gateway. This significantly reduces the workload of testing and prevents the omission of untested functional modules, making it suitable for widespread promotion and use.

[0093] The fifth embodiment of the present invention also provides a gateway testing method. The gateway testing method provided in this embodiment differs from the gateway testing method provided in the first embodiment above in that:

[0094] Furthermore, in this embodiment, it should be noted that after the steps described above, which involve simulating the vehicle's signal environment using VSPY to complete the testing of the gateway in that signal environment through the test cases, the method further includes:

[0095] Receive the test results output by VSPY in real time, and determine whether the test results are within a preset threshold;

[0096] If the test result is determined to be within the preset threshold, the gateway of the current vehicle is determined to meet the factory requirements, and a corresponding test tag is generated based on the test result.

[0097] If the test result is determined to be outside the preset threshold, the gateway of the current vehicle is determined to be non-compliant with the factory requirements, and the gateway of the current vehicle is retested.

[0098] In addition, in this embodiment, it should be noted that in order to enable staff to accurately know the current test results of the vehicle gateway, this embodiment will receive the test results output by the VSPY in real time and immediately determine whether the current test results are within the preset threshold.

[0099] Furthermore, if the current test result is determined to be within the aforementioned preset threshold, it can be determined that the current vehicle's gateway meets the factory requirements. At the same time, a corresponding test label is generated based on the real-time generated test result, and the test label is affixed to the current vehicle to indicate that the current vehicle meets the factory requirements.

[0100] Correspondingly, if it is determined that the current test result is not within the above-mentioned preset threshold, it is determined that the current vehicle's gateway does not meet the factory requirements. Furthermore, this embodiment will retest the current vehicle's gateway to avoid unnecessary test errors.

[0101] It should be noted that the method provided in the fifth embodiment of the present invention has the same implementation principle and some technical effects as the first embodiment. For the sake of brevity, any parts not mentioned in this embodiment can be referred to the corresponding content provided in the first embodiment.

[0102] In summary, the gateway testing method provided by the above embodiments of the present invention can generate corresponding test cases in real time based on the module parameters of each functional module in the vehicle gateway. At the same time, it can also simulate a test environment adapted to the current vehicle gateway in real time, thereby enabling the simultaneous testing of multiple functional modules in the vehicle gateway. This significantly reduces the workload of testing and prevents the omission of untested functional modules, making it suitable for widespread promotion and use.
