[0047] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0048] Refer to Figure 1 , Figure 1 Schematic flow diagram of an interface testing method for the cockpit domain controller provided by an embodiment of the present application. As Figure 1 shown, this interface testing method for the cockpit domain controller is applied to a signal output device. The signal output device includes a first interface module for outputting a digital voltage signal, a second interface module for outputting an analog voltage signal, and a third interface module for outputting a resistance signal. This interface testing method for the cockpit domain controller may include the following steps:

[0049] Step S102, obtain configuration parameters, and perform parameter configuration on the first interface module, the second interface module, and / or the third interface module based on the configuration parameters, where the configuration parameters are determined based on the interface testing requirements of the cockpit domain controller to be tested.

[0050] It should be noted that the interface test method for the cockpit domain controller provided in the embodiments of this application can be applied to a signal output device. The signal output device includes a first interface module for outputting digital voltage signals, a second interface module for outputting analog voltage signals, and a third interface module for outputting resistance signals. The first interface module, the second interface module, and / or the third interface module are respectively electrically connected to different interfaces in the cockpit domain controller to be tested. The signal output device is respectively communicatively connected to the host computer and the cockpit domain controller to be tested. Among them, the first interface module may include one or more digital voltage channels, and each digital voltage channel is used to output one or more digital voltage signals. The value of each digital voltage signal can be flexibly configured according to configuration parameters. For example, the low level in the digital voltage signal can be configured as 0V, and the high level in the digital voltage signal can be configured as 3.3V, 5V, or 12V, etc. The second interface module may include one or more analog voltage channels, and each analog voltage channel is used to output one or more analog voltage signals. The value of the analog voltage signal can be flexibly configured according to configuration parameters. For example, the analog voltage signal can be an analog voltage signal with an output range of 0 to 3.3V, 0 to 5V, or 0 to 12V, etc. The third interface module may include one or more resistance channels, and each resistance channel is used to output one or more resistance signals. The value of the resistance signal can be flexibly configured according to configuration parameters. For example, the resistance signal can be a resistance signal with an output range of 0 to 1M ohm, etc. In addition, the signal output device further includes a communication interface module, a storage module, a processing module, etc., as Figure 2 shown. Among them, the communication interface module supports Controller Area Network (CAN for short) communication, Universal Serial Bus (USB for short) communication, etc. The communication interface module is used to realize the communication between the signal output device and the cockpit domain controller to be tested and the host computer respectively. The storage module is used to store information such as test data, configuration parameters, and program codes. The storage module can be a storage chip such as an Electrically Erasable Programmable Read Only Memory (EEPROM for short), a Flash EEPROM Memory (Flash for short), or an Embedded Multi Media Card (EMMC for short). The processing module is used to realize functions such as data acquisition, processing, and analysis. The host computer here can be a terminal device such as a personal computer, a laptop computer, or a smart phone. The cockpit domain controller to be tested here can be any cockpit domain controller that needs to perform interface testing.

[0051] Since the vehicle cockpit domain controller usually needs to connect to a relatively large number of signals, such as the KL15 switch signal, fuel level signal, seat gravity signal, seat belt wearing signal, and various wake-up signals, etc., and the above signals can be classified into three types according to their electrical characteristics: digital voltage signals, analog voltage signals, and resistance signals. Therefore, the first interface module in the signal output device can be used to provide various digital voltage signals for the cockpit domain controller to be tested, and the second interface module in the signal output device can be used to provide various analog voltage signals for the cockpit domain controller to be tested, and the third interface module in the signal output device can be used to provide various resistance signals for the cockpit domain controller to be tested. This can meet the requirements of the cockpit domain controller to be tested for various signals, so as to implement interface testing on the cockpit domain controller to be tested.

[0052] Specifically, the above configuration parameters refer to the configuration parameters required for parameter configuration of one or more of the first interface module, the second interface module, and the third interface module in the signal output device. The configuration parameters are determined in advance based on the interface test requirements of the cockpit domain controller to be tested. For example, when this interface test only needs to test the interfaces corresponding to 3 digital voltage signals of a certain cockpit domain controller to be tested, only the configuration parameters of the corresponding 3 digital voltage channels in the first interface module need to be obtained; when this interface test needs to test the interfaces corresponding to 2 digital voltage signals, 2 analog voltage signals, and 2 resistance signals of a certain cockpit domain controller to be tested, the configuration parameters of the corresponding 2 digital voltage channels in the first interface module, the corresponding 2 analog voltage channels in the second interface module, and the corresponding 2 resistance channels in the third interface module need to be obtained.

[0053] The way to obtain the configuration parameters can be to directly write the relevant configuration parameters into the signal output device according to the interface test requirements; it can also be to send the relevant configuration parameters to the signal output device through the host computer according to the interface test requirements. The embodiments of the present application do not make specific limitations.

[0054] Step S104: Receive the test instruction sent by the host computer, and in response to the test instruction, control the first interface module to output at least one digital voltage signal, the second interface module to output at least one analog voltage signal, and / or the third interface module to output at least one resistance signal to the cockpit domain controller to be tested.

[0055] Specifically, the above test instruction can be triggered and generated by the user on the host computer and then sent to the signal output device. The test instruction is used to request the signal output device to output corresponding signals for interface testing of the cockpit domain controller to be tested. After receiving the test instruction, the signal output device can control the first interface module to output at least one digital voltage signal, the second interface module to output at least one analog voltage signal, and / or the third interface module to output at least one resistance signal to the cockpit domain controller to be tested according to the pre-configured configuration parameters. It should be noted that the quantity and values of the digital voltage signals output by the first interface module, the quantity and values of the analog voltage signals output by the second interface module, and the quantity and values of the resistance signals output by the third interface module are all determined based on the configuration parameters obtained by the signal output device, and they can be one or multiple to meet the interface testing requirements in different test scenarios.

[0056] Step S106: Receive the test data returned by the cockpit domain controller to be tested and send the test data to the host computer so that the host computer can determine the interface test result based on the test data, where the test data is generated by the cockpit domain controller to be tested in response to receiving at least one digital voltage signal, at least one analog voltage signal, and / or at least one resistance signal.

[0057] When the signal output device outputs digital voltage signals, analog voltage signals, and / or resistance signals to the cockpit domain controller to be tested, the cockpit domain controller to be tested can generate test data based on the received signals. For example, when the signal output device outputs a low-level signal of 0V to a certain interface of the cockpit domain controller to be tested, the cockpit domain controller to be tested can generate a test data for indicating that the seat belt is not worn; when outputting a high-level signal of 3.3V to this interface of the cockpit domain controller to be tested, the cockpit domain controller to be tested can generate a test data for indicating that the seat belt is worn. Another example is that when the signal output device outputs an analog signal with a voltage range of 0 - 3.3V to another interface of the cockpit domain controller to be tested, the cockpit domain controller to be tested can generate a test data for indicating the remaining fuel quantity or water temperature. Still another example is that when the signal output device outputs a resistance signal of 100 ohms to yet another interface of the cockpit domain controller to be tested, the cockpit domain controller to be tested can generate a test data for indicating that someone is sitting on the seat or for multimedia volume control.

[0058] In this way, the signal output device can also receive the test data returned by the cockpit domain controller to be tested and send the test data to the host computer. At this time, the host computer can determine the interface test result based on the test data.

[0059] In the above manner, the signal output device can automatically control the first interface module to output at least one digital voltage signal, the second interface module to output at least one analog voltage signal, and / or the third interface module to output at least one resistance signal to the cockpit domain controller to be tested, so as to meet the interface test requirements of the cockpit domain controller to be tested, without manually testing each interface of the cockpit domain controller, thereby improving the test efficiency.

[0060] In an alternative embodiment, the above step S102, obtaining configuration parameters, includes:

[0061] Receiving a configuration instruction sent by the host computer and parsing the configuration parameters from the configuration instruction, where the configuration parameters are manually configured based on the operation interface of the host computer, and the configuration instruction is manually triggered after the configuration parameters are configured.

[0062] Specifically, the above configuration parameters can be manually configured by the user on the operation interface of the host computer. As Figure 3 shown, the user can select the required digital voltage channels, analog voltage channels, and / or resistance channels on the operation interface of the host computer, and manually set relevant parameters for each selected channel. After the configuration is completed, the user can click the "Save Configuration" button to save the configuration parameters, and can also click the "Configuration Download" button to generate a configuration instruction and send it to the signal output device. In this way, the signal output device can receive the configuration instruction sent by the host computer and parse the configuration parameters from the configuration instruction.

[0063] In the above manner, the user can flexibly set relevant configuration parameters according to the interface test requirements of different cockpit domain controllers, without having to modify the logic in the program code every time the configuration parameters are modified, so the flexibility and practicability are stronger.

[0064] In an alternative embodiment, the above step S104, in response to a test instruction, controlling the first interface module to output at least one digital voltage signal, the second interface module to output at least one analog voltage signal, and / or the third interface module to output at least one resistance signal to the cockpit domain controller to be tested, includes:

[0065] In response to the test instruction, determining at least one digital voltage channel with parameter configuration completed in the first interface module, at least one analog voltage channel with parameter configuration completed in the second interface module, and / or at least one resistance channel with parameter configuration completed in the third interface module, where the first interface module includes multiple digital voltage channels, the second interface module includes multiple analog voltage channels, and the third interface module includes multiple resistance channels;

[0066] Control at least one digital voltage channel to output at least one digital voltage signal, at least one analog voltage channel to output at least one analog voltage signal, and / or at least one resistance channel to output at least one resistance signal to the cockpit domain controller to be tested.

[0067] Specifically, when the signal output device outputs a digital voltage signal, an analog voltage signal, and / or a resistance signal to the cockpit domain controller to be tested, it is necessary to first determine the number of digital voltage channels with parameter configuration completed in the first interface module and the relevant configuration parameters, the number of analog voltage channels with parameter configuration completed in the second interface module and the relevant configuration parameters, and / or the number of resistance channels with parameter configuration completed in the third interface module and the relevant configuration parameters, and then control these digital voltage channels, analog voltage channels, and / or resistance channels to output the corresponding signals to the cockpit domain controller to be tested. In this way, the signal output device can accurately control the relevant channels to output the corresponding signals based on the obtained configuration parameters, thereby realizing the interface test function.

[0068] See Figure 4 , Figure 4 which is a schematic flowchart of another interface test method for the cockpit domain controller provided by the embodiment of the present application. As Figure 4 shown, this interface test method for the cockpit domain controller is applied to the host computer. This interface test method for the cockpit domain controller may include the following steps:

[0069] Step S402: Send a test instruction to the signal output device so that the signal output device, in response to the test instruction, controls the first interface module to output at least one digital voltage signal, the second interface module to output at least one analog voltage signal, and / or the third interface module to output at least one resistance signal to the cockpit domain controller to be tested.

[0070] It should be noted that the interface test method for the cockpit domain controller provided by the embodiment of the present application can be applied to the host computer. The host computer can be a terminal device such as a personal computer, a laptop computer, or a smart phone. The host computer is communicatively connected to the signal output device and is used to send configuration parameters and test instructions to the signal output device. The signal output device is also communicatively connected to the cockpit domain controller to be tested and is used to provide the required digital voltage signal, analog voltage signal, and / or resistance signal for the cockpit domain controller to be tested.

[0071] Specifically, the above test instructions can be generated by the user on the host computer and then sent to the signal output device. The test instructions are used to request the signal output device to output corresponding signals for interface testing of the cockpit domain controller to be tested. After receiving the test instructions, the signal output device can, according to the pre-configured configuration parameters, control the first interface module to output at least one digital voltage signal, the second interface module to output at least one analog voltage signal, and / or the third interface module to output at least one resistance signal to the cockpit domain controller to be tested. It should be noted that the quantity and values of the digital voltage signals output by the first interface module, the quantity and values of the analog voltage signals output by the second interface module, and the quantity and values of the resistance signals output by the third interface module are all determined based on the configuration parameters obtained by the signal output device. They can be one or multiple to meet the interface testing requirements in different test scenarios.

[0072] Step S404: Receive the test data returned by the signal output device, and based on the test data, determine the interface test result, where the test data is generated by the cockpit domain controller to be tested in response to receiving at least one digital voltage signal, at least one analog voltage signal, and / or at least one resistance signal.

[0073] When the signal output device outputs digital voltage signals, analog voltage signals, and / or resistance signals to the cockpit domain controller to be tested, the cockpit domain controller to be tested can generate test data based on the received signals. For example, when the signal output device outputs a low-level signal of 0V to a certain interface of the cockpit domain controller to be tested, the cockpit domain controller to be tested can generate a test data for indicating that the seat belt is not worn. When a high-level signal of 3.3V is output to this interface of the cockpit domain controller to be tested, the cockpit domain controller to be tested can generate a test data for indicating that the seat belt is worn. Another example is that when the signal output device outputs an analog signal with a voltage range of 0 - 3.3V to another interface of the cockpit domain controller to be tested, the cockpit domain controller to be tested can generate a test data for indicating the remaining fuel quantity or water temperature. For another example, when the signal output device outputs a resistance signal of 100 ohms to yet another interface of the cockpit domain controller to be tested, the cockpit domain controller to be tested can generate a test data for indicating that someone is sitting on the seat or for multimedia volume control.

[0074] In this way, the signal output device can receive the test data returned by the cockpit domain controller to be tested and send the test data to the host computer. At this time, the host computer can receive the test data returned by the signal output device and determine the interface test result based on the test data.

[0075] In the above - mentioned manner, the host computer can send a test instruction to the signal output device, so that the signal output device automatically controls the first interface module to output at least one digital voltage signal, the second interface module to output at least one analog voltage signal, and / or the third interface module to output at least one resistance signal to the cockpit domain controller to be tested according to the obtained configuration parameters, so as to meet the interface test requirements of the cockpit domain controller to be tested, without manually testing each interface of the cockpit domain controller, thus improving the test efficiency.

[0076] In an alternative embodiment, before the above - mentioned step S402 of sending a test instruction to the signal output device, the method further includes:

[0077] Sending a configuration instruction to the signal output device, so that the signal output device parses the configuration parameters from the configuration instruction and configures the parameters of the first interface module, the second interface module, and / or the third interface module based on the configuration parameters. Among them, the configuration instruction carries the configuration parameters, and the configuration parameters are determined based on the interface test requirements of the cockpit domain controller to be tested.

[0078] Specifically, the above - mentioned configuration parameters can be manually configured by the user on the operation interface of the host computer. As Figure 3 shown, the user can select the required digital voltage channels, analog voltage channels, and / or resistance channels on the operation interface of the host computer, and manually set the relevant parameters for each selected channel. After the configuration is completed, the user can click the "Save Configuration" button to save the configuration parameters, and can also click the "Configuration Download" button to generate a configuration instruction and send it to the signal output device. In this way, the signal output device can parse the configuration parameters from the configuration instruction and configure the parameters of the first interface module, the second interface module, and / or the third interface module based on the configuration parameters.

[0079] In the above - mentioned manner, the user can flexibly set the relevant configuration parameters by using the host computer according to the interface test requirements of different cockpit domain controllers, without modifying the logic in the program code every time the configuration parameters are modified, so the flexibility and practicality are stronger.

[0080] In an alternative embodiment, the above - mentioned step S404 of determining the interface test result based on the test data includes:

[0081] Determining the test data corresponding to each interface in the cockpit domain controller to be tested from the test data;

[0082] Comparing the test data corresponding to each interface in the cockpit domain controller to be tested with the preset expected values corresponding to each interface in the cockpit domain controller to be tested respectively;

[0083] Based on the comparison results, determine the working states of each interface in the cockpit domain controller to be tested, and based on the working states of each interface in the cockpit domain controller to be tested, determine the interface test results.

[0084] Specifically, when the host computer determines the interface test results based on the test data, it can determine the test data corresponding to each interface in the cockpit domain controller to be tested from the test data, and then compare the test data corresponding to each interface in the cockpit domain controller to be tested with the preset expected values corresponding to each interface in the cockpit domain controller to be tested respectively. Then, according to the comparison results, determine the working states of each interface in the cockpit domain controller to be tested, and based on the working states of each interface in the cockpit domain controller to be tested, determine the interface test results. It should be noted that the preset expected values corresponding to each interface in the cockpit domain controller to be tested can be stored in the host computer in advance. When the test data corresponding to a certain interface in the cockpit domain controller to be tested is consistent with the preset expected value corresponding to this interface, it indicates that the working state of this interface is normal; when the test data corresponding to a certain interface in the cockpit domain controller to be tested is inconsistent with the preset expected value corresponding to this interface, it indicates that the working state of this interface is abnormal, and thus the working states of each interface can be obtained.

[0085] Through the above method, the host computer can determine the working states of each interface in the cockpit domain controller to be tested based on the test data returned by the signal output device, and then automatically obtain the interface test results, without the need for manual reading of the test results of each interface, thereby improving the interface test efficiency.

[0086] In an alternative embodiment, after step S404, determining the interface test results based on the test data, the method further includes:

[0087] Display and export the interface test results.

[0088] Specifically, after the host computer determines the interface test results, it can also display the interface test results. As Figure 5 shown, the host computer can display the test results of each channel. In addition, the host computer can also export the interface test results. For example, the user can click the "Export Data" button in the operation interface to export data such as the configuration parameters and test results of each channel, which is convenient for subsequent problem analysis and processing.

[0089] In an alternative embodiment, the interface test process of the cockpit domain controller provided in the embodiments of the present application is as Figure 6 shown, and it may include the following steps:

[0090] Step S602: Configure the parameters of the signal output device using the host computer.

[0091] The host computer can be communicatively connected to the signal output device through the CAN communication method. According to the interface electrical characteristics of the cockpit domain controller to be tested, it is necessary to configure the parameters of each channel of the first interface module, the second interface module, and the third interface module of the signal output device. The configuration method is as follows:

[0092] a. The first interface module needs to configure the high and low levels of each channel. The typical value of the low-level configuration is 0V, and the typical value of the high-level configuration is 3.3V;

[0093] b. The second interface module needs to configure the voltage range and voltage step value of each channel. The typical value is 0~3.3V, and the step is 0.1V;

[0094] c. The third interface module needs to configure the resistance value of each channel. The typical values are 150 ohms and 1M ohm.

[0095] After the user configures in the host computer, by clicking the "Configuration Download" button, the parameter configuration of the signal output device can be realized. After the signal output device completes the parameter configuration, it can generate a configuration completion flag and send it to the host computer. At this time, the host computer can indicate that the parameter configuration has been completed based on this configuration completion flag.

[0096] Step S604: Test the interfaces corresponding to all digital voltage signals.

[0097] After the parameter configuration is completed, the host computer can send a test instruction to the signal output device, so that the signal output device can sequentially test each channel in the order of the interface corresponding to the preset analog voltage signal, the interface corresponding to the analog voltage signal, and the interface corresponding to the resistance signal.

[0098] When testing the interface corresponding to a certain digital voltage signal in the cockpit domain controller to be tested, the signal output device can first control the corresponding digital voltage channel to output a low level, and obtain the test data of this interface through the CAN message. Then, it controls the corresponding digital voltage channel to output a high level and obtains the test data of this interface through the CAN message. After testing this interface, in the same way as above, test the interface corresponding to the next digital voltage signal in the cockpit domain controller to be tested until all the interfaces corresponding to the digital voltage signals have been tested.

[0099] Step S606: Test the interfaces corresponding to all analog voltage signals.

[0100] When testing an interface corresponding to a certain analog voltage signal in the cockpit domain controller under test, the signal output device can first control the corresponding analog voltage channel to output a 0V voltage, obtain the test data of this interface through a CAN message, then increase the output voltage of this channel in steps of 0.1V, and obtain the test data of this interface through a CAN message every time the output voltage of this channel is increased until the output voltage of this channel reaches the set value. After testing this interface, the next interface corresponding to the analog voltage signal in the cockpit domain controller under test is tested in the same manner as above.

[0101] Step S608: Test all interfaces corresponding to the resistance signals.

[0102] When testing an interface corresponding to a certain resistance signal in the cockpit domain controller under test, the signal output device can control the corresponding resistance channel to output according to the set resistance value, and obtain the test data of this interface through a CAN message every time the resistance value is output until all set resistance values are output. After testing this interface, the next interface corresponding to the resistance signal in the cockpit domain controller under test is tested in the same manner as above.

[0103] Step S610: Analyze the test data and output the test result.

[0104] After all interfaces in the cockpit domain controller under test are tested, the signal output device generates a test completion flag and sends the test completion flag to the host computer. At this time, the host computer can indicate that the interface test has been completed based on this test completion flag. The test results of each channel can be viewed on the host computer, and the test results can be selected for export and analysis.

[0105] Thus, the above interface test method can achieve the following beneficial effects:

[0106] 1. Improve test efficiency and save test costs: The cockpit domain controller has a large number of interfaces. The existing interface test methods basically rely on manual testing, which takes a long time and has low efficiency in the test process; in this application, by combining the signal output device and the host computer, high-efficiency testing can be achieved, and the test results can be quickly analyzed.

[0107] 2. Improve test coverage: Due to the large number of interfaces in the cockpit domain controller, and it is time-consuming and laborious to build a test environment. In order to improve test efficiency, manual testing often uses a sampling method for interfaces, and the test does not cover all interfaces, there is a risk of missing potential problems; while in this application, multiple channels can be set in the first interface module, the second interface module and the third interface module of the signal output device, so the test coverage can be significantly improved.

[0108] 3. Strong compatibility: The electrical parameter specifications of the interfaces of different cockpit domain controllers are different. The signal output device of the present application can be configured to output interface signals with different parameters, so it can be compatible with the interface tests of different cockpit controllers.
