[0002] In the process of car computer development, the user interface (UI) in the car computer is usually developed based on one language (hereinafter referred to as the source language), and the classical Chinese in the user interface is mainly in the source language. When it is necessary to develop a user interface in other language formats, the classical Chinese in the source language format in the user interface can be translated into classical Chinese in other language formats. There are large differences between different languages, so errors are very likely to occur during the classical Chinese translation process. During the car computer testing process, the classical Chinese in other language formats needs to be tested so that errors in the classical Chinese in other language formats can be corrected in time to prevent erroneous classical Chinese from appearing in the user interface.

[0039] Please refer to Figure 1 , Figure 1 This is a flowchart of the steps of an embodiment of the vehicle test method of the present application. According to different requirements, the order of the steps in the flowchart can be changed, and some steps can be omitted. The control method can be applied to terminal devices, but is not limited to this, and the embodiments of the present application are not limited to this.

[0040] In some embodiments, the terminal device may be a device including both receiving and transmitting hardware, that is, a device having receiving and transmitting hardware capable of performing two-way communication on a two-way communication link. Such a device may include: a cellular or other communication device having a single-line display or a multi-line display or a cellular or other communication device without a multi-line display. The terminal device may be a desktop terminal or a mobile terminal, and the terminal device may also be a mobile phone, a tablet computer, a laptop computer, etc., but is not limited thereto.

[0041] The specific process of this embodiment is as follows Figure 1 As shown, the following steps are included: Step 101: Send a language change instruction to a vehicle to change the text language displayed in the vehicle to a first target language.

[0042] In some embodiments, the first target language can be automatically determined by the terminal device. For example, the terminal device can read and parse the test case, which can be an Excel table, and the Excel table stores the language information to be tested. The terminal device generates a language change instruction based on the parsed language information, and the vehicle changes the text language to the first target language after receiving the language change instruction.

[0043] Step 102: Send a test instruction to a display device of the vehicle so that the display device displays a text interface matching the test instruction.

[0044] In some embodiments, the test instruction is an instruction for simulating a specific scenario in which the vehicle is in a specific scenario, and the display device will display a text interface that matches the specific scenario. For example, if the test instruction simulates a scenario in which the vehicle battery is low and needs to be charged, after the terminal device sends the test instruction to the vehicle, the display device will display a text interface including the words "Battery is low, please charge in time".

[0045] It is understandable that this embodiment does not specifically limit the type of test instructions and the display content of the text interface matching the test instructions, and can be set according to the actual configuration of the test vehicle.

[0046] Step 103: Control the display device to perform a screen capture operation to obtain a screenshot of the interface when the display device displays a text interface.

[0047] In some embodiments, the terminal device sends a screenshot command to the display device of the vehicle, and the display device performs a screenshot operation after receiving the screenshot command.

[0048] It is understandable that the specific types of display devices and how to control different types of display devices to perform screenshot operations to obtain interface screenshots are described in detail in subsequent embodiments. In order to avoid repetition, they will not be repeated here.

[0049] Step 104: extract the string from the interface screenshot to obtain the classical Chinese string in the text interface.

[0050] In some embodiments, OCR recognition is performed on the interface screenshot to obtain a classical Chinese character string.

[0051] It should be noted that this embodiment does not specifically limit the method for extracting character strings from the interface screenshot, and other methods can be selected to extract character strings from the interface screenshot according to actual needs.

[0052] In some embodiments, before extracting the string from the interface screenshot, it also includes: determining the location area where the classical Chinese string is located from the text interface according to the preset classical Chinese location information; extracting the string from the interface screenshot to obtain the classical Chinese string in the text interface includes: extracting the string from the location area to obtain the classical Chinese string. In this way, the amount of computation of the terminal device can be reduced, and the efficiency and accuracy of the classical Chinese testing method can be further improved.

[0053] In some embodiments, the classical Chinese position information matches the test instruction. Specifically, as can be seen from the foregoing description, the test instruction is an instruction used to simulate the vehicle being in a specific scene. When the vehicle is in a specific scene and the vehicle functions normally, the display device will display an accurate text interface that matches the specific scene. The position information of the text in the accurate text interface is the preset classical Chinese position information of this embodiment. In this way, the terminal device can directly extract the required classical Chinese string based on the location area, avoiding the influence of other content in the interface screenshot on the string extraction process, and because the content in the location area is far less than the content of the interface screenshot, the efficiency and accuracy of the classical Chinese testing method are improved.

[0054] Step 105 : compare the classical Chinese character string with the standard classical Chinese character string, and detect whether the text displayed in the text interface is correct based on the comparison result, wherein the standard classical Chinese character string is the correct character string displayed by the display device under the test instruction.

[0055] For example, when the vehicle is operating normally, if the battery level of the vehicle is low and needs to be charged, the display device will display a text interface including the words "Battery level is low, please charge in time", and "Battery level is low, please charge in time" is the correct string. A test instruction is sent to the vehicle through the terminal device. The test instruction simulates a scenario where the battery level of the vehicle is low and needs to be charged. After the terminal device sends the test instruction to the vehicle, the display device will display a text interface. If a string is extracted from a screenshot of the text interface, the resulting classical Chinese string is assumed to be "Battery level is low, please charge in time", and the comparison result is that the text display is correct. If the resulting classical Chinese string is assumed to be "Battery level is low, please charge in time", the comparison result is that the text display is incorrect.

[0056] Compared with the related art, the embodiment of the present application has at least the following advantages: by setting the text language displayed by the vehicle to the first target language, so as to facilitate the classical Chinese test of the first target language; by sending a test instruction to the display device of the vehicle, the display device displays a text interface matching the test instruction after receiving the test instruction, and then controlling the display device to perform a screenshot operation to obtain an interface screenshot of the text interface, thereby realizing automatic acquisition of the interface screenshot without manual operation. By extracting the string from the interface screenshot, the classical Chinese string in the text interface can be obtained, and then the classical Chinese string is compared with the standard classical Chinese string, so as to detect whether there is an error in the text actually displayed in the text interface. The entire test process does not require the participation of testers, saving labor costs and ensuring the accuracy of the test, and the vehicle test can be completed in a domestic laboratory, improving the test efficiency.

The implementation environment described in the embodiment of the present application is intended to more clearly illustrate the technical solution of the embodiment of the present application, and does not constitute a limitation on the technical solution provided in the embodiment of the present application. A person of ordinary skill in the art can appreciate that with the emergence of new business scenarios, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

[0099] exist Figure 5 In the embodiment of the present application, the resource scheduling system provided by the embodiment of the present application may include a computer, a CANoe simulation device, a vehicle machine Android system and an instrument QNX system. The computer may be integrated with the vehicle textual language test device provided by the embodiment of the present application.

[0100] The computer is connected to CANoe and the vehicle Android system via a USB cable, the CANoe simulation device is connected to the vehicle Android system via a CAN bus or FlexRay bus, and the vehicle Android system is connected to the instrument QNX system via a Telnet bus or FTP bus.

[0101] It is understandable that the computer can be an independent server, or a server network or server cluster composed of servers. For example, the computer described in the embodiments of the present application includes but is not limited to a computer, a network host, a single network server, a plurality of network server sets or a cloud server composed of multiple servers. Among them, the cloud server is composed of a large number of computers or network servers based on cloud computing.

[0102] The interactive process of the vehicle's textual testing method includes: 1. The computer sends a test command to the CANoe simulation device. The CANoe simulation device sends a message to the vehicle Android system and the instrument QNX system based on the test command. The vehicle Android system and the instrument QNX system display specific classical Chinese prompts according to the message. That is, the vehicle Android system displays the first text interface, and the instrument QNX system displays the second text interface.

[0103] 2. The computer sends an adb command to the vehicle Android system. The vehicle Android system takes a screenshot of the first text interface based on the adb command to obtain a screenshot of the first interface, and then copies the screenshot of the first interface to the local computer through the adb command; the computer logs in to the vehicle Android system, and then logs in to the instrument QNX system through telnet in the vehicle Android system, and then executes the QNX system command in the instrument QNX system to take a screenshot of the instrument screen to obtain a screenshot of the first interface. After completing the screenshot operation, exit the instrument QNX system, return to the vehicle Android system, and copy the screenshot of the second interface in the instrument QNX system to the vehicle Android system through ftp. Finally, copy the screenshot of the second interface from the Android system to the local computer through the adb command.

[0104] 3. The computer calls the OCR algorithm to extract the character string from the first interface screenshot and the second interface screenshot to obtain the classical Chinese character string actually displayed on the vehicle computer and the instrument.

[0105] 4. The computer compares the classical Chinese character string extracted in step 3 with the correct character string to determine whether the character string displayed in this screenshot is correct.

[0106] Compared with the related art, the embodiment of the present application has at least the following advantages: by setting the text language displayed by the vehicle to the first target language, so as to facilitate the classical Chinese test of the first target language; by sending a test instruction to the display device of the vehicle, the display device displays a text interface matching the test instruction after receiving the test instruction, and then controlling the display device to perform a screenshot operation to obtain an interface screenshot of the text interface, thereby realizing automatic acquisition of the interface screenshot without manual operation. By extracting the string from the interface screenshot, the classical Chinese string in the text interface can be obtained, and then the classical Chinese string is compared with the standard classical Chinese string, so as to detect whether there is an error in the text actually displayed in the text interface. The entire test process does not require the participation of testers, saving labor costs and ensuring the accuracy of the test, and the vehicle test can be completed in a domestic laboratory, improving the test efficiency.

[0107] Please refer to Figure 6 , Figure 6 This is a flowchart of the steps of an embodiment of the vehicle language test method of the present application. According to different requirements, the order of the steps in the flowchart can be changed, and some steps can be omitted. The vehicle language test can be applied to the aforementioned terminal device, but is not limited thereto, and the embodiment of the present application does not limit this.

[0108] This embodiment is a further improvement of the above embodiment, and the main improvement is: in this embodiment, there are multiple test instructions and multiple languages ​​to be tested. This embodiment will perform a classical Chinese test of multiple test instructions on each language until all language tests are completed. In this way, the test efficiency and reliability of the classical Chinese test of the vehicle can be further improved.

[0109] The specific process of this embodiment is as follows Figure 6 As shown, the following steps are included: Step 501: Send a language change instruction to a vehicle to change the text language displayed by the vehicle to a first target language.

[0110] Step 502: Send a first test instruction among multiple test instructions to a display device, so that the display device displays a text interface matching the first test instruction.

[0111] Step 503: Control the display device to perform a screenshot operation to obtain a screenshot of the interface when the display device displays the text interface.

[0112] Step 504: extract the string from the interface screenshot to obtain the classical Chinese string in the text interface.

[0113] Step 505: compare the classical Chinese character string with the standard classical Chinese character string, and detect whether the text displayed in the text interface is correct based on the comparison result, wherein the standard classical Chinese character string is the correct character string displayed by the display device under the test instruction.

[0114] Step 506: Send the second test instruction among the multiple test instructions to the display device, and repeat the above steps of controlling the display device to perform the screenshot operation and the character string comparison until all the test instructions are sent to the display device.

[0115] Step 507: Send a new language change instruction to the vehicle to change the text language displayed by the vehicle to the second target language.

[0116] Step 508, repeat the above steps of sending multiple test instructions to the display device, controlling the display device to perform screenshot operations and performing string comparison to complete the classical Chinese test of the second target language, and repeat the above steps of sending new language change instructions and testing the reset language based on multiple test instructions until the classical Chinese test of all languages ​​is completed.

[0117] For ease of understanding, the following Figure 7 The process of the vehicle test of this application is specifically described as follows: Please refer to Figure 7 , which is a flow chart of the vehicle textual testing method provided in an embodiment of the present application.

[0118] 1. According to Figure 5 The Wenyan test system shown completes the connection between the computer, CANoe simulation equipment, vehicle Android system and instrument QNX system.

[0119] 2. Set up an Excel table, which stores test instructions, whether the classical Chinese is displayed on the vehicle computer or the instrument, the classical Chinese position information and the correct string in rows. Different sheets in the Excel table store the above information in different languages, and the sheet page name is named after the language name.

[0120] It should be noted that each test instruction corresponds to a classical Chinese display position (ie, whether the classical Chinese is displayed on the vehicle computer or the instrument, or on the vehicle computer and the instrument), a classical Chinese position information and a correct character string.

[0121] 3. The computer reads and parses the Excel spreadsheet, obtains the number of sheet pages, the name of each sheet page, and the data content of each sheet page. The name of each sheet page contains language information.

[0122] 4. The computer initializes the loop variables i (corresponding to the order of the sheet pages) and j (corresponding to the number of rows of data in each sheet page), with i being initialized to 0 and j being initialized to 1.

[0123] 5. The computer sets the vehicle to the corresponding language according to the sheet page name, such as English, French, German, etc.

[0124] 6. The computer takes the data in the jth row of the ith sheet and parses its contents cell by cell.

[0125] 7. The computer constructs the corresponding signal according to the required signal and timing in the acquired data and sends it to the vehicle computer. That is, if the classical Chinese is required to be displayed on the vehicle computer, the test command is directly sent to the vehicle computer. If the classical Chinese is required to be displayed on the instrument, the test command needs to be forwarded to the instrument through the vehicle computer.

[0126] 8. The computer takes a screenshot on the vehicle computer and the instrument according to the display position of the classical Chinese text, and copies the screenshot file to the local computer. The specific process has been described in detail in the above embodiment and will not be repeated here.

[0127] 9. The computer extracts the classical Chinese display part from the screenshot file based on the classical Chinese position coordinates in the retrieved data and saves it as a separate picture.

[0128] 10. The computer uses the OCR algorithm to extract the character string from the image that only displays classical Chinese in step 9, and obtains the classical Chinese character string actually displayed on the vehicle instrument panel.

[0129] 11. The computer compares the classical Chinese character string extracted in step 10 with the correct character string read from the Excel data to determine whether the character string displayed in this screenshot is correct.

[0130] As of step 11, the automated test of a certain piece of classical Chinese in a certain language has been completed. Starting from step 12, the main task is to determine whether the end condition is met. If the end condition is not met, the process of steps 3-11 is repeated to complete the automatic screenshot, extraction and comparison test of the classical Chinese one by one.

[0131] 12. Add 1 to the variable j. The computer determines whether the value of j after adding 1 is greater than the maximum number of rows on this sheet. If the result is "No", continue to execute steps 6-12; if the result is "Yes", execute step 13.

[0132] 13. The variable i is incremented by 1. The computer determines whether the value of i after incrementing by 1 is greater than the number of sheet pages. If the result is "no", the value of the variable j is reset to 1, and then steps 5-12 are executed; if the result is "yes", the entire program is terminated.

[0133] Compared with the related art, the embodiment of the present application has at least the following advantages: by setting the text language displayed by the vehicle to the first target language, so as to facilitate the classical Chinese test of the first target language; by sending a test instruction to the display device of the vehicle, the display device displays a text interface matching the test instruction after receiving the test instruction, and then controlling the display device to perform a screenshot operation to obtain an interface screenshot of the text interface, thereby realizing automatic acquisition of the interface screenshot without manual operation. By extracting the string from the interface screenshot, the classical Chinese string in the text interface can be obtained, and then the classical Chinese string is compared with the standard classical Chinese string, so as to detect whether there is an error in the text actually displayed in the text interface. The entire test process does not require the participation of testers, saving labor costs and ensuring the accuracy of the test, and the vehicle test can be completed in a domestic laboratory, improving the test efficiency.
