Description

Technical Field

[0001] This application relates to the field of brightness synchronization testing technology, and in particular to a brightness synchronization testing system. Background Technology

[0002] With the rapid development of automotive electronics technology, people have higher and higher requirements for the intelligence of the electronic systems inside vehicles. Among them, the instrument display screen (vehicle dashboard) and the vehicle infotainment display screen (vehicle central control screen) are the two most commonly used electronic display devices in automobiles. The brightness synchronization function between the two directly affects the user experience. Therefore, it is necessary to conduct brightness synchronization tests on the instrument display screen and the vehicle infotainment display screen before the vehicle leaves the factory.

[0003] In related technologies, the brightness synchronization test of instrument panel displays and vehicle infotainment displays is usually carried out by manual visual inspection. Therefore, the testing process is very cumbersome and inefficient, and is easily affected by human visual fatigue. It is difficult to guarantee the accuracy, sustainability and repeatability of the brightness synchronization test. At the same time, due to the inconsistent evaluation of light sensitivity by human vision, it is difficult for developers to discover problems in time during the research and development stage, thereby affecting product quality and market competitiveness. Summary of the Invention

[0004] This application provides a brightness synchronization testing system, which solves the problems of cumbersome testing process and low efficiency in the current manual brightness synchronization testing of instrument panel displays and vehicle displays. It is conducive to improving the accuracy, sustainability and repeatability of brightness synchronization testing. At the same time, the light sensor can ensure the consistency of light sensitivity assessment compared with human vision, which makes it easier for developers to discover problems in time during the research and development stage, thereby improving product quality and market competitiveness.

[0005] To achieve the above objectives, the main technical solutions adopted in this application include:

[0006] In a first aspect, embodiments of this application provide a brightness synchronization testing system, including:

[0007] Test bench, the test bench includes an opaque enclosure;

[0008] Both the instrument panel display and the vehicle infotainment display are housed within a cover.

[0009] A light-blocking component is housed within the enclosure and is suitable for isolating light between the instrument panel display and the vehicle infotainment display.

[0010] The first light sensor and the second light sensor are both located inside the cover.

[0011] The host computer is communicatively connected to the instrument panel display, the vehicle infotainment display, the first light sensor, and the second light sensor. The host computer controls the instrument panel display and the vehicle infotainment display to synchronize their brightness at different brightness levels. It determines the brightness synchronization test results of the instrument panel display and the vehicle infotainment display based on the first standard brightness, the second standard brightness, the first ambient light brightness, and the second ambient light brightness. The first standard brightness is the standard brightness of the instrument panel display after brightness synchronization, the second standard brightness is the standard brightness of the vehicle infotainment display after brightness synchronization, the first ambient light brightness is the ambient light brightness of the instrument panel display after brightness synchronization collected by the first light sensor, and the second ambient light brightness is the ambient light brightness of the vehicle infotainment display after brightness synchronization collected by the second light sensor.

[0012] The brightness synchronization testing system proposed in the first aspect of this application isolates the light between the instrument panel display and the vehicle infotainment display by using a light-blocking component, thereby avoiding interference between the light from each other during the brightness synchronization test. After the upper control unit synchronizes the brightness of the instrument panel display and the vehicle infotainment display at different brightness levels, the upper control unit acquires the first standard brightness of the instrument panel display and the second standard brightness of the vehicle infotainment display after brightness synchronization. At the same time, the first light sensor also collects the first light brightness of the instrument panel display after brightness synchronization and sends it to the upper control unit, and the second light sensor also collects the second light brightness of the vehicle infotainment display after brightness synchronization and sends it to the upper control unit. The upper control unit determines the brightness synchronization test result of the instrument panel display and the vehicle infotainment display based on the first standard brightness, the second standard brightness, the first light brightness, and the second light brightness. This enables automated testing of the brightness synchronization of instrument panel displays and vehicle infotainment displays. The entire testing process requires no manual intervention, solving the problems of cumbersome and inefficient testing methods currently used for manual brightness synchronization testing of instrument panel displays and vehicle infotainment displays. The first and second light sensors ensure consistency in light sensitivity assessment compared to human vision, which helps improve the accuracy of brightness synchronization testing and allows developers to identify problems in a timely manner during the R&D phase, thereby improving product quality and market competitiveness. At the same time, the brightness synchronization testing system ensures that the conditions and environment are consistent for each test, guaranteeing the sustainability and repeatability of brightness synchronization testing.

[0013] Optionally, it also includes: a CAN control module, through which the host computer communicates with the instrument display and the vehicle display. The CAN control module is used to obtain the first standard brightness of the instrument display after brightness synchronization and send it to the host computer. The CAN control module is also used to obtain the second standard brightness of the vehicle display after brightness synchronization and send it to the host computer.

[0014] This setup enables the relay of commands from the host computer through the CAN control module. It can also feed back the acquired first and second standard brightness values ​​to the host computer. The CAN control module is connected to the instrument panel display and the vehicle display via a CAN network cable, which can simulate various vehicle communication conditions, making the test more closely resemble a real communication network.

[0015] Optionally, when the host computer is used to control the brightness synchronization of the instrument display and the vehicle display at different brightness levels, it sends a lighting simulation signal to the CAN control module. The CAN control module controls the instrument display to display a lighting simulation icon based on the lighting simulation signal.

[0016] Therefore, the impact of different simulated lights on the brightness synchronization of the instrument panel display and the vehicle display can be simulated as needed without manual intervention, thus expanding the simulation test range and improving the brightness synchronization test function.

[0017] Optionally, the host computer is also used to send a gear position simulation signal to the CAN control module when the instrument panel display and the vehicle display are synchronized at different brightness levels. The CAN control module controls the instrument panel display to display a gear position simulation icon and controls the vehicle display to display a simulated image of the vehicle's perimeter based on the gear position simulation signal.

[0018] Therefore, the impact of different operating conditions on the brightness synchronization of the instrument panel display and the vehicle display can be simulated as needed without manual intervention, further expanding the simulation test range and improving the brightness synchronization test function.

[0019] Optionally, the instrument panel display and the vehicle infotainment display are connected in communication. The CAN control module is used to acquire brightness synchronization request signals at different brightness levels sent by the vehicle infotainment display. The CAN control module is used to control the instrument panel display and the vehicle infotainment display to synchronize their brightness according to the brightness synchronization request signals.

[0020] With this setup, the brightness synchronization test between the instrument panel display and the vehicle infotainment display can be performed using the brightness synchronization request signal generated by the vehicle infotainment display, thereby simulating manual adjustment operations on the vehicle infotainment display and making the test more closely resemble real-world application scenarios.

[0021] Optionally, it also includes: a robotic arm, which is housed inside the enclosure and communicates with a host computer. The host computer controls the robotic arm to click or slide the virtual brightness synchronization button on the vehicle display screen to generate brightness synchronization request signals at different brightness levels.

[0022] Therefore, by using a robotic arm to simulate manual adjustments on the vehicle's display screen, the testing becomes closer to real-world application scenarios. At the same time, it helps to further improve the automation level of the brightness synchronization testing system, greatly reducing manual intervention and significantly improving testing efficiency.

[0023] Optionally, it also includes: a first camera and a second camera, both of which are housed inside the housing and are connected to a host computer. The host computer is used to acquire the gear position simulation icon displayed on the instrument panel screen captured by the first camera, and to acquire the vehicle perimeter simulation image displayed on the vehicle infotainment screen captured by the second camera. The host computer is also used to determine the gear position simulation results of the instrument panel screen and the vehicle infotainment screen based on the gear position simulation icon and the vehicle perimeter simulation image.

[0024] Therefore, by using the first and second cameras, real-time monitoring of changes in the images displayed on the instrument panel and the vehicle infotainment system is achieved. This enables timely alarms when problems occur during gear position simulation testing, ensuring the normal operation of the gear position simulation test and preventing gear position simulation test failure.

[0025] Optionally, an installation space is formed inside the cover, a light-blocking component is disposed in the installation space and the installation space is divided into a first subspace and a second subspace, an instrument display screen is disposed in the first subspace and a vehicle infotainment display screen is disposed in the second subspace.

[0026] This setup further ensures the independence of the instrument panel display and the vehicle infotainment display during the testing process, and further avoids interference between the light from each other during the brightness synchronization test, which helps to improve the accuracy of the brightness synchronization test.

[0027] Optionally, the first light sensor is located in the first subspace, and the second light sensor is located in the second subspace.

[0028] This configuration reduces the mutual interference between the first and second light sensors, which helps to further improve the accuracy of brightness synchronization testing.

[0029] Optionally, the first camera is located in the first subspace, and the first camera is positioned opposite the instrument display screen;

[0030] The second camera is located in the second subspace and is positioned opposite the vehicle's infotainment display screen.

[0031] This setup avoids mutual interference between the images acquired by the first and second cameras, which helps improve the accuracy of gear position simulation. Attached Figure Description

[0049] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0051] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0052] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components.

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone.

[0054] In this application, "multiple" refers to two or more (including two), and similarly, "multiple groups" refers to two or more (including two), and "multiple pieces" refers to two or more (including two).

[0055] With the rapid development of automotive electronics technology, people have increasingly higher requirements for the intelligence of in-vehicle electronic systems. Among them, the instrument panel display (vehicle dashboard) and the infotainment display (vehicle central control screen) are the two most commonly used electronic display devices in automobiles. The brightness synchronization function between the two directly affects the user experience. For example, when the brightness of the infotainment display decreases, the brightness of the instrument panel display should also decrease accordingly, and when the brightness of the infotainment display increases, the brightness of the instrument panel display should also increase accordingly, so that the user can have a better visual experience. If the brightness difference between the infotainment display and the instrument panel display is too large during the brightness synchronization process, it will greatly affect the user experience, such as causing users to experience glare or other unpleasant sensations. Therefore, in order to ensure that the instrument panel display and the infotainment display can achieve a good brightness synchronization function, it is necessary to conduct brightness synchronization tests on the instrument panel display and the infotainment display before the vehicle leaves the factory.

[0056] In related technologies, the brightness synchronization test of instrument panel displays and vehicle infotainment displays is usually carried out by manual visual inspection. Therefore, the testing process is very cumbersome and inefficient, and is easily affected by human visual fatigue. It is difficult to guarantee the accuracy, sustainability and repeatability of the brightness synchronization test. At the same time, due to the inconsistent evaluation of light sensitivity by human vision, it is difficult for developers to discover problems in time during the research and development stage, thereby affecting product quality and market competitiveness.

[0057] Based on this, this application proposes a brightness synchronization test system 100. The brightness synchronization test system 100 isolates the light between the instrument display screen 2 and the vehicle display screen 3 through the light-blocking component 4, thereby avoiding interference between the light of the instrument display screen 2 and the vehicle display screen 3 during the brightness synchronization test. After the upper control instrument display screen 2 and the vehicle display screen 3 synchronize their brightness at different brightness levels, the upper computer 7 obtains the first standard brightness of the instrument display screen 2 after brightness synchronization and the second standard brightness of the vehicle display screen 3 after brightness synchronization. At the same time, the first light sensor 5 also collects the first light brightness of the instrument display screen 2 after brightness synchronization and sends it to the upper computer 7, and the second light sensor 6 also collects the second light brightness of the vehicle display screen 3 after brightness synchronization and sends it to the upper computer 7. The upper computer 7 determines the brightness synchronization test result of the instrument display screen 2 and the vehicle display screen 3 based on the first standard brightness, the second standard brightness, the first light brightness, and the second light brightness. This achieves automated testing of the brightness synchronization of the instrument panel display 2 and the vehicle infotainment display 3. The entire testing process requires no manual intervention, solving the problems of cumbersome and inefficient testing processes caused by manual brightness synchronization testing of the instrument panel display 2 and the vehicle infotainment display 3. The first light sensor 5 and the second light sensor 6 can ensure consistency in the judgment of light sensitivity compared to human vision, which is conducive to improving the accuracy of brightness synchronization testing. It also makes it easier for developers to identify problems in a timely manner during the R&D stage, thereby improving product quality and market competitiveness. At the same time, the brightness synchronization testing system 100 can ensure that the conditions and environment of each test are consistent, ensuring the sustainability and repeatability of brightness synchronization testing.

[0058] The brightness synchronization test system 100 proposed in this application is described below with reference to the accompanying drawings.

[0059] like Figures 1-2As shown, the brightness synchronization testing system 100 according to the first aspect of this application includes: a test bench 1, an instrument panel display 2 (vehicle dashboard), a vehicle infotainment display 3 (vehicle central control screen), a light-blocking component 4, a first light sensor 5, a second light sensor 6, and a host computer 7. The test bench 1 includes an opaque cover 11. The instrument panel display 2 and the vehicle infotainment display 3 are both disposed within the cover 11. The light-blocking component 4 is disposed within the cover 11 and is adapted to isolate the light between the instrument panel display 2 and the vehicle infotainment display 3. The first light sensor 5 and the second light sensor 6 are both disposed within the cover 11. The host computer 7 is connected to the instrument panel display 2, the vehicle infotainment display 3, the first light sensor 5, and the second light sensor 6. All 6 sensors are connected for communication. The host computer 7 is used to control the instrument display screen 2 and the vehicle display screen 3 to synchronize their brightness at different brightness levels. The host computer 7 determines the brightness synchronization test results of the instrument display screen 2 and the vehicle display screen 3 based on the first standard brightness, the second standard brightness, the first light brightness, and the second light brightness. The first standard brightness is the standard brightness of the instrument display screen 2 after brightness synchronization, the second standard brightness is the standard brightness of the vehicle display screen 3 after brightness synchronization, the first light brightness is the light brightness of the instrument display screen 2 after brightness synchronization collected by the first light sensor 5, and the second light brightness is the light brightness of the vehicle display screen 3 after brightness synchronization collected by the second light sensor 6.

[0060] Specifically, such as Figure 1 and Figure 2 As shown, the test bench 1 is equipped with an opaque cover 11. For example, the cover 11 can be made of opaque (e.g., dark yellow) acrylic glass. The shape of the cover 11 can be rectangular, semi-circular, or other shapes. Furthermore, to enhance the light-blocking effect of the cover 11, a black plastic film is provided on top of the cover 11. The black plastic film can further block the light above the cover 11. With this configuration, when the instrument display screen 2 and the vehicle display screen 3 are installed inside the cover 11, the cover 11 can effectively shield the influence of excess external light on the synchronous brightness testing of the instrument display screen 2 and the vehicle display screen 3, thereby improving the accuracy of the test.

[0061] Continue to refer to Figure 1 and Figure 2As shown, the instrument panel display 2 and the vehicle infotainment display 3 are horizontally arranged within the housing 11. They can be positioned at the same or different horizontal heights; no specific limitation is made here. Furthermore, the instrument panel display 2 and the vehicle infotainment display 3 are spaced apart, with a light-blocking component 4 positioned between them. Optionally, the light-blocking component 4 can be, but is not limited to, a black opaque plastic sheet. This application does not impose specific limitations on the specific location and shape of the light-blocking component 4, as long as it can isolate the light between the instrument panel display 2 and the vehicle infotainment display 3. This arrangement, by placing the light-blocking component 4 between the instrument panel display 2 and the vehicle infotainment display 3, avoids interference between their light sources during brightness synchronization testing. That is, it reduces the interference of light emitted by the instrument panel display 2 on the vehicle infotainment display 3 and vice versa, which helps improve the accuracy of the test.

[0062] The enclosure 11 also contains a first light sensor 5 and a second light sensor 6. It is understood that, for example... Figure 1 and Figure 2 As shown, the first light sensor 5 is positioned above the instrument display screen 2, and the second light sensor 6 is positioned above the vehicle display screen 3. The first light sensor 5 is used to detect the light intensity of the instrument display screen 2, and the second light sensor 6 is used to detect the light intensity of the vehicle display screen 3.

[0063] It should be noted that a host computer 7 is provided outside the cover 11. The host computer 7 is communicatively connected to the first light sensor 5, the second light sensor 6, the instrument display screen 2, and the vehicle display screen 3 inside the cover 11. The communication connection method can be a fiber optic wired communication connection or a wireless communication connection including WIFI and Bluetooth. No specific restrictions are made here.

[0064] When a brightness synchronization test is required for the instrument panel display 2 and the vehicle infotainment display 3, the host computer 7 can issue brightness synchronization test commands to the instrument panel display 2 and the vehicle infotainment display 3 at different brightness levels. The instrument panel display 2 and the vehicle infotainment display 3 will then begin brightness synchronization according to the commands. For example, suppose the instrument panel display 2 and the vehicle infotainment display 3 have five brightness levels: brightness level 1, brightness level 2, brightness level 3, brightness level 4, and brightness level 5. At each brightness level, the instrument panel display 2 and the vehicle infotainment display 3 can synchronize their brightness, and each brightness level has a corresponding first standard brightness and a second standard brightness. That is, the instrument panel display 2 adjusts its brightness according to the preset first standard brightness for each brightness level, and the vehicle infotainment display 3 adjusts its brightness according to the preset first standard brightness for each brightness level. The second standard brightness is used for brightness synchronization adjustment. For example, when the host computer 7 issues brightness synchronization test commands to the instrument display 2 and the vehicle display 3 under brightness level 3, the instrument display 2 adjusts its brightness according to the first standard brightness preset for brightness level 3, and the vehicle display 3 adjusts its brightness according to the second standard brightness preset for brightness level 3. The first standard brightness and the second standard brightness can be preset calibration range values. For example, the first standard brightness of the instrument display 2 under brightness level 3 is [2.5, 3.5], and the second standard brightness of the vehicle display 3 under brightness level 3 is [25, 35]. After the instrument display 2 and the vehicle display 3 are adjusted to brightness level 3 and brightness synchronization is performed, the instrument display 2 and the vehicle display 3 send the first standard brightness and the second standard brightness under brightness level 3 to the host computer 7, respectively.

[0065] Furthermore, when the instrument display 2 and the vehicle display 3 are adjusted to brightness level 3 and brightness synchronization is performed, the first light sensor 5 is used to collect the first light brightness of the instrument display 2 after brightness synchronization under brightness level 3 and send it to the host computer 7, and the second light sensor 6 is used to collect the second light brightness of the vehicle display 3 after brightness synchronization under brightness level 3 and send it to the host computer 7.

[0066] After the host computer 7 obtains the first standard brightness, second standard brightness, first light brightness, and second light brightness under brightness level 3, it determines the brightness synchronization test results of the instrument display screen 2 and the vehicle display screen 3 based on these values. The specific test results are as follows: Under brightness level 3, if the first light brightness obtained by the first light sensor 5 is in the range [2.5, 3.5] (e.g., the first light brightness is 2.5, 3.0, 3.5), and the second light brightness obtained by the second light sensor 6 is in the range [25, 35] (e.g., the first light brightness is 25), then... If the brightness of the instrument panel display 2 is 30 or 35, it indicates that the brightness synchronization function of the vehicle display screen 3 and the instrument panel display screen 2 is successful under the condition of brightness level 3. If the brightness of the first light obtained by the first light sensor 5 is not in the range [2.5, 3.5], for example, the brightness of the first light is 2.0 or 4.0, and / or the brightness of the second light obtained by the second light sensor 6 is not in the range [25, 35], for example, the brightness of the second light is 20 or 40, it indicates that the brightness synchronization function of the instrument panel display 2 and the vehicle display screen 3 is unsuccessful under the condition of brightness level 3. The host computer 7 will record the success and failure of the brightness synchronization function to facilitate later inspection and improvement.

[0067] Furthermore, as another example, when the host computer 7 needs to perform a brightness synchronization test under brightness level 5, the host computer 7 issues a brightness synchronization test command to the instrument display screen 2 and the vehicle display screen 3 respectively under brightness level 5. After the instrument display screen 2 and the vehicle display screen 3 are adjusted to brightness level 5 and brightness synchronization is achieved, the instrument display screen 2 and the vehicle display screen 3 respectively send the first standard brightness and the second standard brightness under brightness level 5 to the host computer 7. The first light sensor 5 is used to collect the first light brightness of the instrument display screen 2 after brightness synchronization under brightness level 5 and send it to the host computer 7. The second light sensor 6 is used to collect the second light brightness of the vehicle display screen 3 after brightness synchronization under brightness level 5 and send it to the host computer 7. After the host computer 7 obtains the first standard brightness, the second standard brightness, the first light brightness, and the second light brightness under brightness level 5, it determines the brightness synchronization test result of the instrument display screen 2 and the vehicle display screen 3 based on the first standard brightness, the second standard brightness, the first light brightness, and the second light brightness under brightness level 5, thereby realizing the brightness synchronization test of the instrument display screen 2 and the vehicle display screen 3 under brightness level 5.

[0068] It should be noted that the host computer 7 can also perform brightness synchronization tests under other brightness levels as needed. This can be done by issuing a brightness synchronization test command under the corresponding brightness level conditions through the host computer 7. The test method is similar to that described above and will not be repeated here.

[0069] In summary, according to the brightness synchronization test system 100 proposed in the first aspect embodiment of this application, the brightness synchronization test system 100 isolates the light between the instrument display screen 2 and the vehicle display screen 3 through the light-blocking component 4, thereby avoiding interference between the light of the instrument display screen 2 and the vehicle display screen 3 during the brightness synchronization test. After the upper control instrument display screen 2 and the vehicle display screen 3 synchronize their brightness at different brightness levels, the upper computer 7 obtains the first standard brightness of the instrument display screen 2 after brightness synchronization and the second standard brightness of the vehicle display screen 3 after brightness synchronization. At the same time, the first light sensor 5 also collects the first light brightness of the instrument display screen 2 after brightness synchronization and sends it to the upper computer 7, and the second light sensor 6 also collects the second light brightness of the vehicle display screen 3 after brightness synchronization and sends it to the upper computer 7. The upper computer 7 determines the brightness synchronization test result of the instrument display screen 2 and the vehicle display screen 3 based on the first standard brightness, the second standard brightness, the first light brightness, and the second light brightness.

[0070] This achieves automated testing of the brightness synchronization of the instrument panel display 2 and the vehicle infotainment display 3. The entire testing process requires no manual intervention, solving the problems of cumbersome and inefficient testing processes caused by manual brightness synchronization testing of the instrument panel display 2 and the vehicle infotainment display 3. The first light sensor 5 and the second light sensor 6 can ensure consistency in the judgment of light sensitivity compared to human vision, which is conducive to improving the accuracy of brightness synchronization testing. It also makes it easier for developers to identify problems in a timely manner during the R&D stage, thereby improving product quality and market competitiveness. At the same time, the brightness synchronization testing system 100 can ensure that the conditions and environment of each test are consistent, ensuring the sustainability and repeatability of brightness synchronization testing.

[0071] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, it also includes: CAN control module 8. The host computer 7 communicates with the instrument display screen 2 and the vehicle display screen 3 through the CAN control module 8. The CAN control module 8 is used to obtain the first standard brightness of the instrument display screen 2 after brightness synchronization and send it to the host computer 7. The CAN control module 8 is also used to obtain the second standard brightness of the vehicle display screen 3 after brightness synchronization and send it to the host computer 7.

[0072] Specifically, the CAN control module 8 is connected to the instrument panel display 2 and the vehicle infotainment display 3 via a CAN network cable. The host computer 7 sends brightness synchronization test commands at different brightness levels to the CAN control module 8. The CAN control module 8 controls the instrument panel display 2 and the vehicle infotainment display 3 to synchronize their brightness according to the brightness synchronization test commands. In other words, the brightness synchronization test commands are first sent from the host computer 7 to the CAN control module 8, and then the CAN control module 8 controls the instrument panel display 2 and the vehicle infotainment display 3 to synchronize their brightness. The brightness synchronization test commands can be preset in the test cases. The host computer 7 directly sends the test cases to the CAN control module 8, and the CAN control module 8 parses the sent test cases to obtain the corresponding brightness synchronization test commands.

[0073] Furthermore, after the instrument panel display 2 and the vehicle infotainment display 3 synchronize their brightness according to the brightness synchronization test command, the instrument panel display 2 and the vehicle infotainment display 3 respectively send the first standard brightness and the second standard brightness at the corresponding brightness level to the CAN control module 8, and then the CAN control module 8 feeds back to the host computer 7. This configuration allows the CAN control module 8 to relay commands issued to the host computer 7, and also to feed back the acquired first and second standard brightness to the host computer 7. The CAN control module 8 is connected to the instrument panel display 2 and the vehicle infotainment display 3 via a CAN network cable, enabling the simulation of various vehicle communication conditions and making the test more closely resemble a real communication network.

[0074] In some embodiments of this application, the host computer 7 sends a lighting simulation signal to the CAN control module 8 when controlling the instrument display screen 2 and the vehicle display screen 3 to synchronize their brightness at different brightness levels. The CAN control module 8 then controls the instrument display screen 2 to display a lighting simulation icon based on the lighting simulation signal.

[0075] Specifically, this application can also simulate the display of light simulation icons on the instrument panel display 2 to detect the effect of the light simulation icons on the brightness synchronization of the instrument panel display 2 and the vehicle display 3. The light simulation icons displayed on the instrument panel display 2 can be low beam icons, high beam icons, position light icons, or ignition icons, etc.

[0076] As a concrete example, let's take brightness level 3 as an illustration. When it's necessary to detect the impact of the low beam headlight icon displayed on the instrument panel display 2 at brightness level 3 on the brightness synchronization of the instrument panel display 2 and the vehicle infotainment display 3, the host computer 7 sends a brightness synchronization test command and a low beam headlight simulation signal to the CAN control module 8 at brightness level 3. The CAN control module 8 controls the instrument panel display 2 to display the low beam headlight icon and adjusts the brightness synchronization according to the first standard brightness preset for brightness level 3. Simultaneously, the CAN control module 8 also controls the vehicle infotainment display 3 to adjust the brightness synchronization according to the second standard brightness preset for brightness level 3. It's understandable that displaying the low beam headlight icon on the instrument panel display 2 might cause a change in the first standard brightness, for example, changing it to [3.0, 4.0]. Similarly, the brightness of the first light source collected by the first light sensor 5 will also change.

[0077] After the brightness of the instrument panel display 2 and the vehicle infotainment display 3 is synchronized, the first light sensor 5 collects the first light brightness when the instrument panel display 2 displays the low beam headlight icon under brightness level 3 and sends it to the CAN control module 8. The second light sensor 6 collects the second light brightness of the vehicle infotainment display 3 under brightness level 3 and sends it to the CAN control module 8. Finally, the CAN control module 8 feeds back to the host computer 7 the first standard brightness, second standard brightness, first light brightness, and second light brightness when the instrument panel display 2 displays the low beam headlight icon under brightness level 3. The host computer 7 determines the brightness synchronization test result of the instrument panel display 2 and the vehicle infotainment display 3 based on the acquired first standard brightness, second standard brightness, first light brightness, and second light brightness.

[0078] For example, under brightness level 3 and when the instrument display 2 shows the low beam headlight icon, the first standard brightness of the instrument display 2 is [3.0, 4.0], and the second standard brightness of the vehicle display 3 under brightness level 3 is [25, 35]. If the first light brightness obtained by the first light sensor 5 is in the range [3.0, 4.0], for example, the first light brightness is 3.0, 3.5, 4.0, and the second light brightness obtained by the second light sensor 6 is in the range [25, 35], for example, the first light brightness is 25, 30, 35, then it means that the instrument display 2 and the vehicle display 3 are under brightness level 3 and the instrument display shows... The brightness synchronization function is successful when the low beam headlight icon is displayed on screen 2. Under brightness level 3, if the brightness of the first light source obtained by the first light sensor 5 is not in the range [3.0, 4.0], for example, the brightness of the first light source is 2.0 or 5.0, and / or the brightness of the second light source obtained by the second light sensor 6 is not in the range [25, 35], for example, the brightness of the second light source is 20 or 40, it means that the brightness synchronization function of the instrument display screen 2 and the vehicle display screen 3 is unsuccessful under brightness level 3 and when the instrument display screen 2 displays the low beam headlight icon. The host computer 7 will record both the success and failure of the brightness synchronization function to facilitate later inspection and improvement.

[0079] Furthermore, as another example, taking brightness level 3 as an example, when it is necessary to detect the effect of the high beam icon displayed on the instrument display screen 2 on the brightness synchronization of the instrument display screen 2 and the vehicle display screen 3 under the brightness level 3 condition, the host computer 7 issues a brightness synchronization test command under the brightness level 3 condition and a high beam simulation signal to the CAN control module 8. The specific test process is similar to the test process described above for detecting the low beam icon displayed on the instrument display screen 2 under the brightness level 3 condition, and will not be repeated here.

[0080] Therefore, the effect of different simulated lights on the brightness synchronization of the instrument display screen 2 and the vehicle display screen 3 can be simulated as needed without manual intervention, thus expanding the simulation test range and improving the brightness synchronization test function.

[0081] In some embodiments of this application, the host computer 7 is also used to send a gear position simulation signal to the CAN control module 8 when the instrument display screen 2 and the vehicle display screen 3 are synchronized at different brightness levels. The CAN control module 8 controls the instrument display screen 2 to display a gear position simulation icon and controls the vehicle display screen 3 to display a vehicle perimeter simulation image according to the gear position simulation signal.

[0082] Specifically, this application can also simulate the display of a gear position simulation icon on the instrument panel display 2 and the display of a vehicle surrounding simulation image on the vehicle infotainment display 3, in order to detect the influence of the gear position simulation icon and the vehicle surrounding simulation image on the brightness synchronization of the instrument panel display 2 and the vehicle infotainment display 3. The gear position simulation icon displayed on the instrument panel display 2 can be a forward gear icon or a reverse gear icon, and the vehicle surrounding simulation image displayed on the vehicle infotainment display 3 can be a 360° vehicle surrounding simulation image or a reverse gear simulation image.

[0083] As a specific example, let's take brightness level 3 as an illustration. When it's necessary to detect the impact of the reverse gear icon displayed on instrument panel display 2 and the reverse gear simulation image displayed on vehicle infotainment display 3 on the brightness synchronization of instrument panel display 2 and vehicle infotainment display 3 under brightness level 3 conditions, the host computer 7 sends a brightness synchronization test command and a reverse gear simulation signal to the CAN control module 8 under brightness level 3 conditions. The CAN control module 8 controls instrument panel display 2 to display the reverse gear icon and adjusts the brightness synchronization according to the first standard brightness preset for brightness level 3. Simultaneously, the CAN control module 8 also controls vehicle infotainment display 3 to display the reverse gear simulation image and adjusts the brightness synchronization according to the second standard brightness preset for brightness level 3. It's understandable that displaying the reverse gear icon on instrument panel display 2 might cause a change in the first standard brightness, for example, changing it to [3.0, 4.0]. Similarly, the brightness of the first light source collected by the first light sensor 5 will also change. Similarly, displaying the reverse gear simulation image on vehicle infotainment display 3 might cause a change in the second standard brightness, for example, changing it to [30, 40]. Likewise, the brightness of the second light source collected by the second light sensor 6 will also change.

[0084] After the brightness of the instrument panel display 2 and the vehicle infotainment display 3 is synchronized, the first light sensor 5 collects the first light intensity of the instrument panel display 2 when it displays the reverse gear icon under brightness level 3 and sends it to the CAN control module 8. The second light sensor 6 collects the second light intensity of the vehicle infotainment display 3 when it displays the reverse gear simulation image under brightness level 3 and sends it to the CAN control module 8. Finally, the CAN control module 8 feeds back to the host computer 7 the first standard brightness, second standard brightness, first light intensity, and second light intensity when the instrument panel display 2 displays the reverse gear icon and the vehicle infotainment display 3 displays the reverse gear simulation image under brightness level 3. The host computer 7 determines the brightness synchronization test result of the instrument panel display 2 and the vehicle infotainment display 3 based on the acquired first standard brightness, second standard brightness, first light intensity, and second light intensity.

[0085] For example, under brightness level 3 and when the instrument panel display 2 shows the reverse gear icon, the first standard brightness of the instrument panel display 2 is [3.0, 4.0]. Under brightness level 3 and when the vehicle infotainment display 3 shows the reverse gear simulation image, the second standard brightness of the vehicle infotainment display 3 is [30, 40]. If the first light brightness obtained by the first light sensor 5 is in the range [3.0, 4.0], for example, the first light brightness is 3.0, 3.5, 4.0, and the second light brightness obtained by the second light sensor 6 is in the range [30, 40], for example, the first light brightness is 30, 35, 40, then it means that the instrument panel display 2 and the vehicle infotainment display 3 are under brightness level 3 and the instrument panel display 2 shows the reverse gear icon. The brightness synchronization function of the instrument display screen 2 and the vehicle display screen 3 when displaying the reverse gear simulation image is successful. Under the condition of brightness level 3, if the brightness of the first light obtained by the first light sensor 5 is not in the range [3.0, 4.0], for example, the brightness of the first light is 2.0 or 5.0, and / or, the brightness of the second light obtained by the second light sensor 6 is not in the range [3.0, 4.0], for example, the brightness of the second light is 20 or 50, it means that the brightness synchronization function of the instrument display screen 2 and the vehicle display screen 3 under the condition of brightness level 3, when the instrument display screen 2 displays the reverse gear icon and the vehicle display screen 3 displays the reverse gear simulation image, is unsuccessful. The host computer 7 will record the success and failure of the brightness synchronization function, so as to facilitate later search and improvement.

[0086] Furthermore, as another example, taking brightness level 3 as an example, when it is necessary to detect the impact of the forward gear icon displayed on the instrument panel display 2 and the 360° vehicle surround simulation image displayed on the vehicle display 3 on the brightness synchronization of the instrument panel display 2 and the vehicle display 3 under brightness level 3 conditions, the host computer 7 issues a brightness synchronization test command and a forward gear simulation signal under brightness level 3 conditions to the CAN control module 8. The specific test process is similar to the test process described above for detecting the reverse gear icon displayed on the instrument panel display 2 and the reverse gear simulation image displayed on the vehicle display 3 under brightness level 3 conditions, and will not be repeated here.

[0087] Therefore, the impact of different operating conditions on the brightness synchronization of the instrument display screen 2 and the vehicle display screen 3 can be simulated as needed without manual intervention, further expanding the simulation test range and improving the brightness synchronization test function.

[0088] In some embodiments of this application, the instrument display 2 and the vehicle display 3 are communicatively connected. The CAN control module 8 is used to acquire brightness synchronization request signals at different brightness levels sent by the vehicle display 3. The CAN control module 8 is used to control the instrument display 2 and the vehicle display 3 to synchronize their brightness according to the brightness synchronization request signals.

[0089] Specifically, the vehicle display screen 3 has a controller inside. The controller can send brightness synchronization request signals at different brightness levels to the CAN control module 8 according to the test requirements. The CAN control module 8 then controls the instrument display screen 2 and the vehicle display screen 3 to synchronize their brightness according to the brightness synchronization request signals. The brightness synchronization request signals generated by the controller of the vehicle display screen 3 can come from the test cases of the host computer 7, and no specific restrictions are made here.

[0090] Furthermore, the vehicle infotainment display 3 controller can generate brightness synchronization request signals at different brightness levels. For example, the vehicle infotainment display 3 controller generates a brightness synchronization request signal at brightness level 3 and sends it to the CAN control module 8. The CAN control module 8 controls the instrument panel display 2 and the vehicle infotainment display 3 to synchronize their brightness according to the brightness synchronization request signal. With this setup, the brightness synchronization of the instrument panel display 2 and the vehicle infotainment display 3 can be tested using the brightness synchronization request signal generated by the vehicle infotainment display 3, thereby simulating manual adjustment operations on the vehicle infotainment display 3 and making the test more closely resemble real-world application scenarios.

[0091] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, it also includes: a robotic arm 9, which is located inside the housing 11 and is connected to the host computer 7. The host computer 7 is used to control the robotic arm 9 to click or slide the brightness synchronization virtual button on the vehicle display screen 3 to generate brightness synchronization request signals at different brightness levels.

[0092] Specifically, the robotic arm 9 in this application can be used to simulate human hand operations such as clicking or sliding on the vehicle infotainment display 3. Specifically, the host computer 7 is used to send test cases to the robotic arm 9. For example, the test cases may include a brightness synchronization test instruction for the instrument panel display 2 and the vehicle infotainment display 3 under brightness level 3. The robotic arm 9, according to the brightness synchronization test instruction, controls itself to click or slide the virtual brightness synchronization button on the vehicle infotainment display 3 to cause the vehicle infotainment display 3 controller to generate a brightness synchronization request signal under brightness level 3. As a specific example, using brightness level 3 as an example, the generated brightness synchronization request signal under brightness level 3 is fed back to the CAN control module 8. The CAN control module 8 controls the instrument panel display based on the brightness synchronization request signal. The instrument panel display 2 adjusts its brightness synchronously according to the first standard brightness preset in brightness level 3, and simultaneously controls the vehicle display screen 3 to adjust its brightness synchronously according to the second standard brightness preset in brightness level 3. The first standard brightness and the second standard brightness can be preset calibration range values. For example, under brightness level 3, the first standard brightness of the instrument panel display 2 is [2.5, 3.5], and the second standard brightness of the vehicle display screen 3 is [25, 35]. After the instrument panel display 2 and the vehicle display screen 3 are adjusted to brightness level 3 and synchronized, the instrument panel display 2 and the vehicle display screen 3 respectively send the first standard brightness and the second standard brightness under brightness level 3 to the CAN control module 8, so that they can be sent to the host computer 7 through the CAN control module 8.

[0093] Furthermore, after the instrument display 2 and the vehicle display 3 are adjusted to brightness level 3 and brightness synchronization is performed, the first light sensor 5 is used to collect the first light brightness of the instrument display 2 after brightness synchronization under brightness level 3 and send it to the CAN control module 8. The second light sensor 6 is used to collect the second light brightness of the vehicle display 3 after brightness synchronization under brightness level 3 and send it to the CAN control module 8. Finally, the first light brightness and the second light brightness are sent to the host computer 7 through the CAN control module 8.

[0094] After the host computer 7 obtains the first standard brightness, second standard brightness, first light brightness, and second light brightness under brightness level 3, it determines the brightness synchronization test results of the instrument display screen 2 and the vehicle display screen 3 based on these values. The specific test results are as follows: Under brightness level 3, if the first light brightness obtained by the first light sensor 5 is in the range [2.5, 3.5] (e.g., the first light brightness is 2.5, 3.0, 3.5), and the second light brightness obtained by the second light sensor 6 is in the range [25, 35] (e.g., the first light brightness is 25), then... If the brightness of the instrument panel display 2 is 30 or 35, it indicates that the brightness synchronization function of the vehicle display screen 3 and the instrument panel display screen 2 is successful under the condition of brightness level 3. If the brightness of the first light obtained by the first light sensor 5 is not in the range [2.5, 3.5], for example, the brightness of the first light is 2.0 or 4.0, and / or the brightness of the second light obtained by the second light sensor 6 is not in the range [25, 35], for example, the brightness of the second light is 20 or 40, it indicates that the brightness synchronization function of the instrument panel display 2 and the vehicle display screen 3 is unsuccessful under the condition of brightness level 3. The host computer 7 will record the success and failure of the brightness synchronization function to facilitate later inspection and improvement.

[0095] Therefore, by using the robotic arm 9 to simulate manual adjustment operations on the vehicle display screen 3, the test becomes closer to the real application scenario. At the same time, it helps to further improve the automation level of the brightness synchronization test system 100, greatly reduces manual intervention, and significantly improves the efficiency of the test.

[0096] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, it also includes: a first camera 10 and a second camera 20. The first camera 10 and the second camera 20 are both located inside the cover 11, and the first camera 10 and the second camera 20 are both connected to the host computer 7. The host computer 7 is used to acquire the gear simulation icon displayed on the instrument display screen 2 captured by the first camera 10, and to acquire the vehicle perimeter simulation image displayed on the vehicle display screen 3 captured by the second camera 20. The host computer 7 is also used to determine the gear simulation results of the instrument display screen 2 and the vehicle display screen 3 based on the gear simulation icon and the vehicle perimeter simulation image.

[0097] Specifically, the first camera 10 is used to acquire images displayed on the instrument panel display 2 in real time, and the second camera 20 is used to acquire images displayed on the vehicle infotainment display 3 in real time. When the host computer 7 controls the instrument panel display 2 and the vehicle infotainment display 3 to synchronize brightness at different brightness levels and sends a gear position simulation signal to the CAN control module 8, the first camera 10 is used to acquire the gear position simulation icon displayed on the instrument panel display 2 and send it to the host computer 7, and the second camera 20 is used to acquire the vehicle perimeter simulation image displayed on the vehicle infotainment display 3 and send it to the host computer 7. The host computer 7 is also used to determine the gear position simulation based on the gear position simulation icon and the vehicle perimeter simulation image. The gear simulation results of instrument panel display 2 and vehicle infotainment display 3 are as follows: If instrument panel display 2 displays the forward gear icon and vehicle infotainment display 3 displays a 360° vehicle surround simulation image, or instrument panel display 2 displays the reverse gear icon and vehicle infotainment display 3 displays a reverse gear simulation image, then the gear simulation is successful. If instrument panel display 2 displays the forward gear icon but vehicle infotainment display 3 displays a reverse gear simulation image, or instrument panel display 2 displays the reverse gear icon but vehicle infotainment display 3 displays a 360° vehicle surround simulation image, then the gear simulation fails. In this case, the brightness synchronization test system will issue a 100 alarm to indicate that the test has failed.

[0098] Therefore, the first camera 10 and the second camera 20 enable real-time monitoring of changes in the images displayed on the instrument panel display 2 and the vehicle display 3. This allows for timely alarms when problems occur during gear position simulation testing, ensuring the normal operation of the gear position simulation test and preventing gear position simulation test failure.

[0099] In some embodiments of this application, such as Figure 2 As shown, an installation space 111 is formed inside the cover 11. The light-blocking component 4 is disposed in the installation space 111 and divides the installation space 111 into a first subspace 1111 and a second subspace 1112. The instrument display screen 2 is disposed in the first subspace 1111 and the vehicle display screen 3 is disposed in the second subspace 1112.

[0100] Specifically, the light-blocking component 4 can divide the installation space 111 into a first subspace 1111 and a second subspace 1112 that are not connected to each other. The instrument display screen 2 is placed in the first subspace 1111 and the vehicle display screen 3 is placed in the second subspace 1112. This arrangement can further ensure the independence of the instrument display screen 2 and the vehicle display screen 3 during the testing process, and further avoid interference between the light of the instrument display screen 2 and the vehicle display screen 3 during the brightness synchronization test, which is conducive to further improving the accuracy of the brightness synchronization test.

[0101] In some embodiments of this application, such as Figure 2As shown, the first light sensor 5 is located in the first subspace 1111, and the second light sensor 6 is located in the second subspace 1112. That is, the first light sensor 5 and the second light sensor 6 are each located in an independent space. The first light sensor 5 is used to detect the light intensity of the instrument display screen 2 within the first subspace 1111, and the second light sensor 6 is used to detect the light intensity of the vehicle infotainment display screen 3 within the second subspace 1112. This arrangement reduces the mutual interference between the first light sensor 5 and the second light sensor 6, which helps to further improve the accuracy of brightness synchronization testing.

[0102] In some embodiments of this application, such as Figure 2 As shown, the first camera 10 is located in the first subspace 1111, and is positioned opposite to the instrument panel display 2. The second camera 20 is located in the second subspace 1112, and is positioned opposite to the vehicle infotainment display 3. In other words, the first camera 10 and the second camera 20 are each located in an independent space. The first camera 10 is used to detect the image displayed on the instrument panel display 2 within the first subspace 1111, and the second camera 20 is used to detect the image displayed on the vehicle infotainment display 3 within the second subspace 1112. This arrangement avoids mutual interference between the images acquired by the first camera 10 and the second camera 20, which helps improve the accuracy of gear shift simulation.

[0103] Furthermore, to enable those skilled in the art to better understand this solution, this application also provides a test flowchart of the brightness synchronization test system. For example... Figure 3 As shown, the test process includes:

[0104] S201, the host computer 7 edits test cases. Specifically, the operator starts the host computer 7 and edits test cases on it. The test cases include the actions of the robotic arm 9 clicking or sliding the virtual button for brightness synchronization on the vehicle display screen 3, the simulated light or gear position signals to be simulated by the CAN control module 8, the display image information collected by the first camera 10 and the second camera 20, and the light intensity information collected by the first light sensor 5 and the second light sensor 6, etc.

[0105] S202, Execute test cases. Robotic arm 9, first camera 10, second camera 20, first light sensor 5, and second light sensor 6 execute their respective instructions in the test cases.

[0106] S203, the robotic arm 9 clicks or slides the vehicle infotainment display 3 to control the brightness synchronization of the instrument panel display 2 and the vehicle infotainment display 3. The robotic arm 9 clicks or slides the virtual brightness synchronization button on the vehicle infotainment display 3 to generate brightness synchronization request signals at different brightness levels. The CAN control module 8 is used to control the brightness synchronization of the instrument panel display 2 and the vehicle infotainment display 3 according to the brightness synchronization request signals. For example, by clicking the virtual brightness synchronization button, the brightness synchronization setting interface of the vehicle infotainment display 3 is entered. Then, the brightness synchronization function is enabled by clicking, and the brightness level value is set by sliding. At this time, the screen brightness of the vehicle infotainment display 3 and the instrument panel display 2 begins to synchronize.

[0107] In S204, the CAN control module 8 executes either a lighting simulation signal or a gear position simulation signal. S204 is synchronized with S203. When the CAN control module 8 sends a lighting simulation signal, it controls the instrument display screen 2 to display a lighting simulation icon based on the signal. When the CAN control module 8 sends a gear position simulation signal, it controls the instrument display screen 2 to display a gear position simulation icon and controls the vehicle infotainment display screen 3 to display a simulated image of the vehicle's perimeter. This is to improve the brightness synchronization between the vehicle infotainment display screen 3 and the instrument display screen 2 under different driving conditions.

[0108] S205, the first light sensor 5 and the second light sensor 6 collect light intensity. The first light sensor 5 is used to collect the first light intensity of the instrument display screen 2 after brightness synchronization, and the second light sensor 6 is used to collect the second light intensity of the instrument display screen 2 after brightness synchronization.

[0109] S206, the first camera 10 and the second camera 20 acquire and display images. The first camera 10 is used to acquire the gear position simulation icon displayed on the instrument display screen 2, and the second camera 20 is used to acquire the simulated image of the vehicle's perimeter displayed on the vehicle infotainment display screen 3.

[0110] S207, CAN control module 8 collects the first and second standard brightness values. S205, S206, and S207 are performed synchronously.

[0111] S208, the host computer 7 acquires the test results. The host computer 7 determines the brightness synchronization test results of the instrument display screen 2 and the vehicle display screen 3 based on the acquired first standard brightness, second standard brightness, first light brightness, and second light brightness. At the same time, it also acquires the gear simulation test results based on the image information collected by the first camera 10 and the second camera 20.
