[0002] With the rapid development of automotive electronic technology, people have higher and higher requirements for the intelligence of the vehicle's internal electronic system. Among them, the instrument display screen (vehicle dashboard) and the car computer display screen (vehicle central control large screen) are the two most commonly used electronic display devices in the car. The brightness synchronization function between the two directly affects the user experience. Therefore, it is necessary to perform a brightness synchronization test on the instrument display screen and the car computer display screen before the vehicle leaves the factory.

[0003] In related technologies, the brightness synchronization test of the instrument display screen and the vehicle computer display screen is usually detected by human naked eyes. Therefore, the testing process is very cumbersome and inefficient, and is easily affected by human visual fatigue. It is difficult to ensure the accuracy, sustainability and repeatability of the brightness synchronization test. At the same time, due to the inconsistent judgment of human vision on light sensitivity, it is difficult for developers to find problems in time during the R&D stage, which affects product quality and market competitiveness. Summary of the invention

[0004] The present application provides a brightness synchronization test system, which solves the problems of cumbersome test process and low efficiency caused by the current manual brightness synchronization test of instrument display screens and vehicle display screens, and is conducive to improving the accuracy, sustainability and repeatability of brightness synchronization test. At the same time, the light sensor can ensure the consistency of light sensitivity judgment relative to artificial vision, which is convenient for developers to discover problems in time during the research and development stage, thereby improving product quality and market competitiveness.

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

[0006] In a first aspect, an embodiment of the present application provides a brightness synchronization test system, comprising:

[0007] A test bench, the test bench comprising a light-proof cover;

[0008] The instrument display screen and the vehicle computer display screen are both arranged in the cover body;

[0009] A light isolating member, which is disposed in the cover and is suitable for isolating light between the instrument display screen and the vehicle display screen;

[0010] A first light sensor and a second light sensor, both of which are arranged in the cover;

[0011] The upper computer is communicatively connected with the instrument display screen, the vehicle computer display screen, the first light sensor, and the second light sensor. The upper computer is used to control the brightness synchronization of the instrument display screen and the vehicle computer display screen at different brightness levels, and determine the brightness synchronization test results of the instrument display screen and the vehicle computer display screen according to the first standard brightness, the second standard brightness, the first light brightness, and the second light brightness, wherein the first standard brightness is the standard brightness of the instrument display screen after brightness synchronization, the second standard brightness is the standard brightness of the vehicle computer display screen after brightness synchronization, the first light brightness is the light brightness of the instrument display screen after brightness synchronization collected by the first light sensor, and the second light brightness is the light brightness of the vehicle computer display screen after brightness synchronization collected by the second light sensor.

[0012] The brightness synchronization test system proposed in the first aspect of the embodiment of the present application, the brightness synchronization test system isolates the light between the instrument display screen and the vehicle computer display screen through a light isolation member, thereby avoiding interference of each other's light during the brightness synchronization test of the instrument display screen and the vehicle computer display screen. After the upper computer controls the instrument display screen and the vehicle computer display screen to perform brightness synchronization at different brightness levels, the upper computer obtains the first standard brightness of the instrument display screen after brightness synchronization and the second standard brightness of the vehicle computer display screen after brightness synchronization. At the same time, the first light sensor also collects the first light brightness of the instrument display screen after brightness synchronization and sends it to the upper computer, and the second light sensor also collects the second light brightness of the vehicle computer display screen after brightness synchronization and sends it to the upper computer. The upper computer determines the brightness synchronization test results of the instrument display screen and the vehicle computer display screen according to the first standard brightness, the second standard brightness, the first light brightness, and the second light brightness. As a result, automated testing of the brightness synchronization of the instrument display and the vehicle display is achieved. The entire testing process does not require human intervention, which solves the problems of cumbersome testing process and low efficiency caused by the current manual brightness synchronization testing of the instrument display and the vehicle display. The first light sensor and the second light sensor can ensure the consistency of light sensitivity judgment relative to artificial vision, which is conducive to improving the accuracy of the brightness synchronization test and makes it easier for developers to discover problems in a timely manner during the R&D stage, thereby improving product quality and market competitiveness.

[0017] Optionally, the host computer is also used to send a gear simulation signal to the CAN control module when controlling the brightness synchronization of the instrument display screen and the vehicle computer display screen at different brightness levels. The CAN control module controls the instrument display screen to display the gear simulation icon according to the gear simulation signal, and controls the vehicle computer display screen to display a simulated image around the vehicle.

[0018] In this way, the impact of different gear working conditions on the brightness synchronization of the instrument display screen and the vehicle computer display screen can be simulated as needed without manual intervention and adjustment, which further expands the simulation test range and further improves the brightness synchronization test function.

[0054] With the rapid development of automotive electronic technology, people have higher and higher requirements for the intelligence of the vehicle's internal electronic system. Among them, the instrument display screen (vehicle dashboard) and the car computer display screen (vehicle central control large screen) are the two most commonly used electronic display devices in the car. The brightness synchronization function between the two directly affects the user experience. For example, when the brightness of the car computer display screen decreases, the brightness of the instrument display screen must also decrease. When the brightness of the car computer display screen increases, the brightness of the instrument display screen must also increase, so that the user can get a better visual experience. If the brightness difference between the car computer display screen and the instrument display screen is too large during the brightness synchronization process, it will greatly affect the user experience, such as making the user feel glare and other unpleasant feelings. Therefore, in order to ensure that the instrument display screen and the car computer display screen can achieve a good brightness synchronization function, it is necessary to perform a brightness synchronization test on the instrument display screen and the car computer display screen before the vehicle leaves the factory.

[0055] In related technologies, the brightness synchronization test of the instrument display screen and the vehicle computer display screen is usually detected by human naked eyes. Therefore, the testing process is very cumbersome and inefficient, and is easily affected by human visual fatigue. It is difficult to ensure the accuracy, sustainability and repeatability of the brightness synchronization test. At the same time, due to the inconsistent judgment of human vision on light sensitivity, it is difficult for developers to find problems in time during the R&D stage, which affects product quality and market competitiveness.

[0056] Based on this, the present application proposes a brightness synchronization test system 100, which isolates the light between the instrument display screen 2 and the vehicle display screen 3 through a light isolation member 4, thereby avoiding interference of each other's light during the brightness synchronization test of the instrument display screen 2 and the vehicle display screen 3. After the upper control instrument display screen 2 and the vehicle display screen 3 perform brightness synchronization 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 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 results of the instrument display screen 2 and the vehicle display screen 3 according to the first standard brightness, the second standard brightness, the first light brightness, and the second light brightness. Thus, the automated test of the brightness synchronization of the instrument display screen 2 and the vehicle display screen 3 is realized, and the entire test process does not require human intervention, which solves the problems of cumbersome test process and low efficiency caused by the current manual brightness synchronization test of the instrument display screen 2 and the vehicle display screen 3. The first light sensor 5 and the second light sensor 6 can ensure the consistency of light sensitivity judgment relative to artificial vision, which is beneficial to improving the accuracy of the brightness synchronization test and facilitates developers to discover problems in time during the research and development stage, thereby improving product quality and market competitiveness. At the same time, the brightness synchronization test system 100 can ensure that the conditions and environment of each test are consistent, thereby ensuring the sustainability and repeatability of the brightness synchronization test.

[0057] The brightness synchronization test system 100 proposed in the embodiment of the present application is described below with reference to the accompanying drawings.

[0058] like Figure 1-Figure 2As shown, according to the brightness synchronization test system 100 of the first embodiment of the present application, it includes: a test bench 1, an instrument display screen 2 (vehicle instrument panel), a vehicle display screen 3 (vehicle central control large screen), a light isolation member 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 display screen 2 and the vehicle display screen 3 are both arranged in the cover 11, the light isolation member 4 is arranged in the cover 11, and the light isolation member 4 is suitable for isolating the light between the instrument display screen 2 and the vehicle display screen 3, the first light sensor 5 and the second light sensor 6 are both arranged in the cover 11, the host computer 7 and the instrument display screen 2, the vehicle display screen 3, the first light sensor 5, the second light sensor The sensors 6 are all communicatively connected, and the host computer 7 is used to control the brightness synchronization of the instrument display screen 2 and the vehicle display screen 3 at different brightness levels, and determine the brightness synchronization test results of the instrument display screen 2 and the vehicle display screen 3 according to the first standard brightness, the second standard brightness, the first light brightness, and the second light brightness, wherein 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.

[0059] Specifically, Figure 1 and Figure 2 As shown, the test bench 1 is provided with an opaque cover 11. For example, the cover 11 can be made of an opaque (such as dark yellow) acrylic glass plate. The shape of the cover 11 can be rectangular, or semicircular or other shapes. Further, in order to enhance the light-shielding effect of the cover 11, a black plastic film is provided above the cover 11. The black plastic film can further block the light above the cover 11. With such a configuration, when the instrument display screen 2 and the vehicle display screen 3 are installed in the cover 11, the cover 11 can well shield the influence of the extra external light on the brightness synchronization test of the instrument display screen 2 and the vehicle display screen 3, thereby facilitating the improvement of the accuracy of the test.

[0060] Continue to refer Figure 1 and Figure 2As shown, the instrument display screen 2 and the vehicle display screen 3 are horizontally arranged in the cover body 11. The instrument display screen 2 and the vehicle display screen 3 can be arranged at the same horizontal height or at different horizontal heights, and no specific restrictions are made here. Furthermore, the instrument display screen 2 and the vehicle display screen 3 are arranged at intervals, and a light isolation member 4 is provided between the instrument display screen 2 and the vehicle display screen 3. Optionally, the light isolation member 4 can be selected from but not limited to a black opaque plastic plate. The present application does not make specific restrictions on the specific position and shape of the light isolation member 4, and it is sufficient to isolate the light between the instrument display screen 2 and the vehicle display screen 3. In this way, by providing a light isolation member 4 between the instrument display screen 2 and the vehicle display screen 3, it is possible to avoid interference of light from each other between the instrument display screen 2 and the vehicle display screen 3 during the brightness synchronization test, that is, to reduce the interference of light generated by the instrument display screen 2 on the vehicle display screen 3 and to reduce the interference of light generated by the vehicle display screen 3 on the instrument display screen 2, which is conducive to improving the accuracy of the test.

[0061] The cover body 11 is also provided with a first light sensor 5 and a second light sensor 6. It can be understood that Figure 1 and Figure 2 As shown, the first light sensor 5 is arranged above the instrument display screen 2, and the second light sensor 6 is arranged 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.

[0062] It should be noted that a host computer 7 is provided outside the cover body 11, and the host computer 7 is communicatively connected with the first light sensor 5, the second light sensor 6, the instrument display screen 2, and the vehicle display screen 3 inside the cover body 11, wherein the communication connection method can be a fiber optic wired communication connection, or it can be a wireless communication connection including WIFI and Bluetooth, and no specific restrictions are made here.

[0063] When it is necessary to perform a brightness synchronization test on the instrument display screen 2 and the vehicle computer display screen 3, the upper computer 7 can issue brightness synchronization test instructions to the instrument display screen 2 and the vehicle computer display screen 3 at different brightness levels, and the instrument display screen 2 and the vehicle computer display screen 3 start brightness synchronization according to the brightness synchronization test instructions. As a specific example, it is assumed that the instrument display screen 2 and the vehicle computer display screen 3 have 5 brightness levels, namely brightness level 1, brightness level 2, brightness level 3, brightness level 4, and brightness level 5, wherein at each brightness level, the instrument display screen 2 and the vehicle computer display screen 3 can perform brightness synchronization, and the instrument display screen 2 and the vehicle computer display screen 3 have corresponding first standard brightness and second standard brightness at each brightness level, that is, the instrument display screen 2 performs brightness synchronization adjustment according to the first standard brightness preset for the corresponding brightness level, and the vehicle computer display screen 3 adjusts the brightness according to the preset brightness of the corresponding brightness level. For example, when the host computer 7 issues brightness synchronization test instructions under brightness level 3 to the instrument display 2 and the vehicle display 3 respectively, the instrument display 2 performs brightness synchronization adjustment according to the first standard brightness preset at brightness level 3, and the vehicle display 3 performs brightness synchronization adjustment according to the second standard brightness preset at brightness level 3, wherein the first standard brightness and the second standard brightness can be preset calibration interval values, assuming that 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]. When 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 respectively send the first standard brightness and the second standard brightness under brightness level 3 to the host computer 7.

[0064] Furthermore, when the instrument display screen 2 and the vehicle display screen 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 screen 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 screen 3 after brightness synchronization under brightness level 3 and send it to the host computer 7.

[0065] After the host computer 7 obtains the first standard brightness, the second standard brightness, the first light brightness, and the second light brightness under the brightness level 3, the brightness synchronization test results of the instrument display screen 2 and the vehicle display screen 3 are determined according to the first standard brightness, the second standard brightness, the first light brightness, and the second light brightness under the brightness level 3. The specific test results are as follows: under the brightness level 3, if the first light brightness obtained by the first light sensor 5 is in the interval [2.5, 3.5], for example, 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 interval [25, 35], for example, the first light brightness is 25 , 30, 35, it means that the brightness synchronization function of the instrument display screen 2 and the vehicle display screen 3 is successful under the condition of brightness level 3; 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 interval [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 interval [25, 35], for example, the brightness of the second light is 20 or 40, 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 fails, and the host computer 7 will record the success and failure of the brightness synchronization function, so as to facilitate later search and improvement.

[0066] Further, as another example, when the host computer 7 needs to perform a brightness synchronization test under the condition of brightness level 5, the host computer 7 issues a brightness synchronization test instruction to the instrument display screen 2 and the vehicle display screen 3 under the condition of brightness level 5 respectively. When the instrument display screen 2 and the vehicle display screen 3 are adjusted to brightness level 5 and brightness synchronization is performed, the instrument display screen 2 and the vehicle display screen 3 respectively send the first standard brightness and the second standard brightness under the condition of brightness level 5 to the host computer 7, and the first light sensor 5 is used to collect the first light brightness of the instrument display screen 2 after brightness synchronization under the condition of brightness level 5 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 screen 3 after brightness synchronization under the condition of 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 the condition of brightness level 5, the brightness synchronization test results of the instrument display screen 2 and the vehicle display screen 3 are determined according to the first standard brightness, the second standard brightness, the first light brightness, and the second light brightness under the condition of brightness level 5, thereby realizing the brightness synchronization test of the instrument display screen 2 and the vehicle display screen 3 under the condition of brightness level 5.

[0067] It should be noted that the host computer 7 can also perform brightness synchronization tests under other brightness level conditions as needed, and the host computer 7 can issue brightness synchronization test instructions under corresponding brightness level conditions. The test method is similar to the above and will not be repeated here.

[0068] To summarize, according to the brightness synchronization test system 100 proposed in the embodiment of the first aspect of the present 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 isolation member 4, thereby avoiding the interference of the light of each other during the brightness synchronization test of the instrument display screen 2 and the vehicle display screen 3. After the upper control instrument display screen 2 and the vehicle display screen 3 perform brightness synchronization 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. 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 results of the instrument display screen 2 and the vehicle display screen 3 according to the first standard brightness, the second standard brightness, the first light brightness, and the second light brightness.

[0069] Thus, the automated test of the brightness synchronization of the instrument display screen 2 and the vehicle display screen 3 is realized, and the entire test process does not require human intervention, which solves the problems of cumbersome test process and low efficiency caused by the current manual brightness synchronization test of the instrument display screen 2 and the vehicle display screen 3. The first light sensor 5 and the second light sensor 6 can ensure the consistency of light sensitivity judgment relative to artificial vision, which is beneficial to improving the accuracy of the brightness synchronization test and facilitates developers to discover problems in time during the research and development stage, thereby improving product quality and market competitiveness. At the same time, the brightness synchronization test system 100 can ensure that the conditions and environment of each test are consistent, thereby ensuring the sustainability and repeatability of the brightness synchronization test.

[0070] In some embodiments of the present application, Figure 1 and Figure 2 As shown, it also includes: a CAN control module 8, the host computer 7 is communicated 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, and 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.

[0071] Specifically, the CAN control module 8 is connected to the instrument display screen 2 and the vehicle display screen 3 through a CAN network cable. The upper computer 7 sends brightness synchronization test instructions at different brightness levels to the CAN control module 8. The CAN control module 8 controls the instrument display screen 2 and the vehicle display screen 3 for brightness synchronization according to the brightness synchronization test instructions. That is to say, the brightness synchronization test instructions are first sent to the CAN control module 8 through the upper computer 7, and then the instrument display screen 2 and the vehicle display screen 3 are controlled for brightness synchronization through the CAN control module 8. Among them, the brightness synchronization test instructions can be preset in the test case. The upper computer 7 directly sends the test case to the CAN control module 8, and the CAN control module 8 obtains the corresponding brightness synchronization test instructions according to the analysis of the sent test case.

[0072] Furthermore, after the instrument display screen 2 and the vehicle display screen 3 perform brightness synchronization according to the brightness synchronization test instruction, the instrument display screen 2 and the vehicle display screen 3 send the first standard brightness and the second standard brightness at the corresponding brightness level to the CAN control module 8 respectively, and then feedback to the host computer 7 through the CAN control module 8. In this way, the transmission of the instructions issued by the host computer 7 is realized by setting the CAN control module 8, and the first standard brightness and the second standard brightness obtained can also be fed back to the host computer 7. The CAN control module 8 is connected to the instrument display screen 2 and the vehicle display screen 3 through the CAN network cable, which can simulate various vehicle conditions and make the test closer to the real communication network.

[0073] In some embodiments of the present application, the host computer 7 sends a light simulation signal to the CAN control module 8 when controlling the brightness synchronization of the instrument display screen 2 and the vehicle display screen 3 at different brightness levels, and the CAN control module 8 controls the instrument display screen 2 to display the light simulation icon according to the light simulation signal.

[0074] Specifically, the present application can also simulate the display of light simulation icons on the instrument display screen 2 to detect the impact of the light simulation icons on the brightness synchronization of the instrument display screen 2 and the vehicle display screen 3, wherein the light simulation icons displayed on the instrument display screen 2 can be low beam icons, high and low beam icons, position light icons or ignition icons, etc.

[0075] As a specific example, still taking brightness level 3 as an example, when it is necessary to detect the influence of the low beam icon displayed on the instrument display screen 2 under the condition of brightness level 3 on the brightness synchronization of the instrument display screen 2 and the vehicle display screen 3, the upper computer 7 issues a brightness synchronization test instruction and a low beam simulation signal under the condition of brightness level 3 to the CAN control module 8, and the CAN control module 8 controls the instrument display screen 2 to display the low beam icon and adjusts the brightness synchronously according to the first standard brightness preset at brightness level 3. At the same time, the CAN control module 8 also controls the vehicle display screen 3 to adjust the brightness synchronously according to the second standard brightness preset at brightness level 3. It can be understood that the display of the low beam icon on the instrument display screen 2 may cause a change in the first standard brightness, such as a change in the first standard brightness to [3.0, 4.0]. Similarly, the brightness of the first light collected by the first light sensor 5 will also change.

[0076] When the brightness of the instrument display screen 2 and the vehicle display screen 3 are synchronized, the first light sensor 5 collects the first light brightness when the instrument display screen 2 displays the low beam icon after brightness synchronization under the brightness level 3 condition and sends it to the CAN control module 8. The second light sensor 6 is used to collect the second light brightness of the vehicle display screen 3 after brightness synchronization under the brightness level 3 condition and send it to the CAN control module 8. Finally, the first standard brightness, the second standard brightness, the first light brightness, and the second light brightness under the brightness level 3 condition and when the instrument display screen 2 displays the low beam icon are fed back to the upper computer 7 through the CAN control module 8. The upper computer 7 determines the brightness synchronization test results of the instrument display screen 2 and the vehicle display screen 3 according to the acquired first standard brightness, second standard brightness, first light brightness, and second light brightness.

[0077] For example, under the condition of brightness level 3 and when the instrument display screen 2 displays the low beam icon, the first standard brightness of the instrument display screen 2 is [3.0, 4.0], and the second standard brightness of the vehicle display screen 3 under the condition of brightness level 3 is [25, 35]. If the first light brightness obtained by the first light sensor 5 is in the interval [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 interval [25, 35], for example, the first light brightness is 25, 30, 35, then it means that the instrument display screen 2 and the vehicle display screen 3 are under the condition of brightness level 3 and the instrument display The brightness synchronization function is successful when screen 2 displays the low beam icon; 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 interval [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 interval [25, 35], for example, the brightness of the second light is 20 or 40, then it means that the brightness synchronization function of the instrument display screen 2 and the vehicle display screen 3 fails under the condition of brightness level 3 and the instrument display screen 2 displays the low beam icon. The host computer 7 will record the success and failure of the brightness synchronization function, so as to facilitate later search and improvement.

[0078] Furthermore, as another example, still taking brightness level 3 as an example, when it is necessary to detect the influence of the high beam icon displayed on the instrument display screen 2 under brightness level 3 on the brightness synchronization of the instrument display screen 2 and the vehicle display screen 3, the upper computer 7 issues a brightness synchronization test instruction and a high beam simulation signal under brightness level 3 to the CAN control module 8. The specific test process is similar to the above-mentioned test process of detecting the low beam icon displayed on the instrument display screen 2 under brightness level 3, and will not be repeated here.

[0079] Therefore, the influence 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 and adjustment, thereby expanding the simulation test range and improving the brightness synchronization test function.

[0080] In some embodiments of the present application, the host computer 7 is also used to send a gear simulation signal to the CAN control module 8 when controlling the instrument display screen 2 and the vehicle display screen 3 to perform brightness synchronization at different brightness levels. The CAN control module 8 controls the instrument display screen 2 to display the gear simulation icon according to the gear simulation signal, and controls the vehicle display screen 3 to display a simulated image around the vehicle.

[0081] Specifically, the present application can also simulate the instrument display screen 2 to display the gear simulation icon and simulate the vehicle display screen 3 to display the vehicle surrounding simulation image, so as to detect the influence of the gear simulation icon and the vehicle surrounding simulation image on the brightness synchronization of the instrument display screen 2 and the vehicle display screen 3, wherein the gear simulation icon displayed on the instrument display screen 2 can be a forward gear icon or a reverse gear icon, and the vehicle surrounding simulation image displayed on the vehicle display screen 3 can be a 360° vehicle surrounding simulation image or a reverse gear simulation image.

[0082] As a specific example, still taking brightness level 3 as an example, when it is necessary to detect the influence of the display of the reverse gear icon on the instrument display screen 2 and the display of the reverse gear simulation image on the brightness synchronization of the instrument display screen 2 and the vehicle display screen 3 under the condition of brightness level 3, the upper computer 7 issues a brightness synchronization test instruction and a reverse gear simulation signal under the condition of brightness level 3 to the CAN control module 8, and the CAN control module 8 controls the instrument display screen 2 to display the reverse gear icon and adjusts the brightness synchronously according to the first standard brightness preset at brightness level 3. At the same time, the CAN control module 8 also controls the vehicle display screen 3 to display the reverse gear simulation image and adjusts the brightness synchronously according to the second standard brightness preset at brightness level 3. It can be understood that the display of the reverse gear icon on the instrument display screen 2 may cause the change of the first standard brightness, such as the change of the first standard brightness to [3.0, 4.0]. Similarly, the brightness of the first light collected by the first light sensor 5 will also change. At the same time, the display of the reverse gear simulation image on the vehicle display screen 3 may cause the change of the second standard brightness, such as the change of the second standard brightness to [30, 40]. Similarly, the brightness of the second light collected by the second light sensor 6 will also change.

[0083] When the brightness of the instrument display screen 2 and the vehicle computer display screen 3 are synchronized, the first light sensor 5 collects the first light brightness when the instrument display screen 2 displays the reverse gear icon after brightness synchronization under the brightness level 3 condition and sends it to the CAN control module 8, the second light sensor 6 collects the second light brightness of the vehicle computer display screen 3 when the vehicle computer display screen 3 displays the reverse gear simulation image after brightness synchronization under the brightness level 3 condition and sends it to the CAN control module 8, and finally the first standard brightness, second standard brightness, first light brightness, and second light brightness under the brightness level 3 condition and when the instrument display screen 2 displays the reverse gear icon and the vehicle computer display screen 3 displays the reverse gear simulation image are fed back to the upper computer 7 through the CAN control module 8, and the upper computer 7 determines the brightness synchronization test result of the instrument display screen 2 and the vehicle computer display screen 3 according to the acquired first standard brightness, second standard brightness, first light brightness, and second light brightness.

[0084] For example, under the condition of brightness level 3 and when the instrument display screen 2 displays the reverse gear icon, the first standard brightness of the instrument display screen 2 is [3.0, 4.0], and under the condition of brightness level 3 and when the vehicle display screen 3 displays the reverse gear simulation image, the second standard brightness of the vehicle display screen 3 is [30, 40]. If the first light brightness acquired by the first light sensor 5 is in the interval [3.0, 4.0], for example, the first light brightness is 3.0, 3.5, 4.0, and the second light brightness acquired by the second light sensor 6 is in the interval [30, 40], for example, the first light brightness is 30, 35, 40, then it means that the instrument display screen 2 and the vehicle display screen 3 are under the condition of brightness level 3 and the instrument display screen 2 displays the reverse gear icon And the brightness synchronization function is successful when the vehicle display screen 3 displays the reverse gear simulation image; 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 interval [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 interval [3.0, 4.0], for example, the brightness of the second light is 20 or 50, then it means that the instrument display screen 2 and the vehicle display screen 3 are under the condition of brightness level 3 and the instrument display screen 2 displays the reverse gear icon and the vehicle display screen 3 displays the reverse gear simulation image. The brightness synchronization function fails, and the upper computer 7 will record the success and failure of the brightness synchronization function, so as to facilitate later search and improvement.

[0085] Further, as another example, still taking brightness level 3 as an example, when it is necessary to detect the impact of the forward gear icon displayed on the instrument display screen 2 and the 360° vehicle surrounding simulated image displayed on the vehicle computer display screen 3 on the brightness synchronization of the instrument display screen 2 and the vehicle computer display screen 3 under brightness level 3, the upper computer 7 issues a brightness synchronization test instruction and a forward gear simulation signal under brightness level 3 to the CAN control module 8. The specific test process is similar to the above-mentioned test process of detecting the reverse gear icon displayed on the instrument display screen 2 and the reverse gear simulated image displayed on the vehicle computer display screen 3 under brightness level 3, and will not be repeated here.

[0086] Therefore, the influence of different gear working 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 and adjustment, which further expands the simulation test range and further improves the brightness synchronization test function.

[0087] In some embodiments of the present application, the instrument display screen 2 and the vehicle display screen 3 are communicatively connected, and the CAN control module 8 is used to obtain the brightness synchronization request signal at different brightness levels sent by the vehicle display screen 3, and the CAN control module 8 is used to control the brightness synchronization of the instrument display screen 2 and the vehicle display screen 3 according to the brightness synchronization request signal.

[0088] Specifically, the vehicle display screen 3 has a controller inside, and the controller can send brightness synchronization request signals at different brightness levels to the CAN control module 8 according to test requirements. The CAN control module 8 controls the instrument display screen 2 and the vehicle display screen 3 to synchronize the brightness according to the brightness synchronization request signal. The brightness synchronization request signal generated by the controller of the vehicle display screen 3 can come from the test case of the host computer 7, and no specific restrictions are made here.

[0089] Furthermore, the controller of the vehicle display screen 3 can generate brightness synchronization request signals at different brightness levels. For example, the controller of the vehicle display screen 3 generates a brightness synchronization request signal under the condition of brightness level 3 and sends it to the CAN control module 8. The CAN control module 8 controls the instrument display screen 2 and the vehicle display screen 3 to synchronize brightness according to the brightness synchronization request signal. In this way, the brightness synchronization test of the instrument display screen 2 and the vehicle display screen 3 can be performed through the brightness synchronization request signal generated by the vehicle display screen 3, thereby simulating the manual adjustment operation on the vehicle display screen 3, making the test closer to the real application scenario.

[0090] In some embodiments of the present application, Figure 1 and Figure 2 As shown, it also includes: a mechanical arm 9, which is arranged in the cover body 11 and is communicated with the host computer 7, and the host computer 7 is used to control the mechanical arm 9 to click or slide the brightness synchronization virtual button of the vehicle display screen 3 to generate brightness synchronization request signals under different brightness levels.

[0091] Specifically, the robotic arm 9 in the present application can be used to simulate operations such as clicking or sliding of a human hand on the vehicle display screen 3. Specifically, the upper computer 7 is used to send test cases to the robotic arm 9. For example, the test case includes a brightness synchronization test instruction for the instrument display screen 2 and the vehicle display screen 3 under the condition of brightness level 3. The robotic arm 9 controls the robotic arm 9 to click or slide the brightness synchronization virtual button on the vehicle display screen 3 according to the brightness synchronization test instruction so that the vehicle display screen 3 controller generates a brightness synchronization request signal under the condition of brightness level 3. As a specific example, the brightness level 3 is taken as an example for explanation. The generated brightness synchronization request signal under the condition of brightness level 3 is fed back to the CAN control module 8, and the CAN control module 8 controls the instrument display according to the brightness synchronization request signal. The instrument display screen 2 is synchronously adjusted in brightness according to the first standard brightness preset at the brightness level 3, and the vehicle display screen 3 is synchronously adjusted in brightness according to the second standard brightness preset at the brightness level 3, wherein the first standard brightness and the second standard brightness can be preset calibration interval values. Assuming that the first standard brightness of the instrument display screen 2 under the brightness level 3 condition is [2.5, 3.5], and the second standard brightness of the vehicle display screen 3 under the brightness level 3 condition is [25, 35], when the instrument display screen 2 and the vehicle display screen 3 are adjusted to the brightness level 3 and the brightness is synchronized, the instrument display screen 2 and the vehicle display screen 3 respectively send the first standard brightness and the second standard brightness under the brightness level 3 condition to the CAN control module 8, so as to be sent to the host computer 7 through the CAN control module 8.

[0092] Furthermore, when the instrument display screen 2 and the vehicle display screen 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 screen 2 after brightness synchronization under brightness level 3 and send it to the CAN control module 8, and 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 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.

[0093] After the host computer 7 obtains the first standard brightness, the second standard brightness, the first light brightness, and the second light brightness under the brightness level 3, the brightness synchronization test results of the instrument display screen 2 and the vehicle display screen 3 are determined according to the first standard brightness, the second standard brightness, the first light brightness, and the second light brightness under the brightness level 3. The specific test results are as follows: under the brightness level 3, if the first light brightness obtained by the first light sensor 5 is in the interval [2.5, 3.5], for example, 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 interval [25, 35], for example, the first light brightness is 25 , 30, 35, it means that the brightness synchronization function of the instrument display screen 2 and the vehicle display screen 3 is successful under the condition of brightness level 3; 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 interval [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 interval [25, 35], for example, the brightness of the second light is 20 or 40, 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 fails, and the host computer 7 will record the success and failure of the brightness synchronization function, so as to facilitate later search and improvement.

[0094] Therefore, by simulating the manual adjustment operation on the vehicle display screen 3 through the robotic arm 9, the test is closer to the real application scenario. At the same time, it is conducive to further improving the automation level of the brightness synchronization test system 100, greatly reducing manual intervention, and greatly improving the efficiency of the test.

[0095] In some embodiments of the present application, 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 arranged in the cover body 11, and the first camera 10 and the second camera 20 are both communicatively connected to the host computer 7, the host computer 7 is used to obtain the gear simulation icon displayed on the instrument display screen 2 captured by the first camera 10, and is used to obtain the vehicle surrounding simulation image displayed on the vehicle display screen 3 captured by the second camera 20, and the host computer 7 is also used to determine the gear simulation results of the instrument display screen 2 and the vehicle surrounding simulation image.

[0096] Specifically, the first camera 10 is used to collect the image displayed on the instrument display screen 2 in real time, and the second camera 20 is used to collect the image displayed on the vehicle display screen 3 in real time. When the host computer 7 controls the instrument display screen 2 and the vehicle display screen 3 to synchronize brightness at different brightness levels and sends a gear simulation signal to the CAN control module 8, the first camera 10 is used to obtain the gear simulation icon displayed on the instrument display screen 2 and send it to the host computer 7, and the second camera 20 is used to obtain the simulated image of the vehicle surroundings displayed on the vehicle display screen 3 and send it to the host computer 7. The host computer 7 is also used to determine the gear simulation icon and the simulated image of the vehicle surroundings according to the gear simulation icon and the simulated image of the vehicle surroundings. The gear simulation results of the instrument display screen 2 and the vehicle computer display screen 3 are determined. The specific test results are as follows: if the instrument display screen 2 displays the forward gear icon and the vehicle computer display screen 3 displays a 360° simulated image around the vehicle, or the instrument display screen 2 displays the reverse gear icon and the vehicle computer display screen 3 displays a reverse gear simulated image, it means that the gear simulation is successful. If the instrument display screen 2 displays the forward gear icon but the vehicle computer display screen 3 displays a reverse gear simulated image, or the instrument display screen 2 displays the reverse gear icon but the vehicle computer display screen 3 displays a 360° simulated image around the vehicle, it means that the gear simulation has failed. At this time, the brightness synchronization test system 100 alarms to remind that the test has failed.

[0097] Therefore, real-time monitoring of image changes displayed on the instrument display screen 2 and the vehicle display screen 3 is achieved through the first camera 10 and the second camera 20, and timely alarm can be issued when problems occur in the gear simulation test, thereby ensuring the normal progress of the gear simulation test and avoiding failure of the gear simulation test.

[0098] In some embodiments of the present application, Figure 2 As shown, an installation space 111 is formed in the cover body 11, the light isolation member 4 is arranged 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 arranged in the first subspace 1111, and the vehicle display screen 3 is arranged in the second subspace 1112.

[0099] Specifically, the light isolation member 4 can divide the installation space 111 into a first subspace 1111 and a second subspace 1112 which are not connected to each other, and respectively arrange the instrument display screen 2 in the first subspace 1111 and the vehicle display screen 3 in the second subspace 1112. Such arrangement can further ensure the mutual independence of the instrument display screen 2 and the vehicle display screen 3 during the testing process, further avoid interference of light from each other between the instrument display screen 2 and the vehicle display screen 3 during the brightness synchronization test, and help to further improve the accuracy of the brightness synchronization test.

[0100] In some embodiments of the present application, Figure 2As shown, the first light sensor 5 is arranged in the first subspace 1111, and the second light sensor 6 is arranged in the second subspace 1112. That is to say, the first light sensor 5 and the second light sensor 6 are arranged in independent spaces respectively, the first light sensor 5 is used to detect the light intensity of the instrument display screen 2 in the first subspace 1111, and the second light sensor 6 is used to detect the light intensity of the vehicle display screen 3 in the second subspace 1112. Such arrangement reduces the mutual influence between the first light sensor 5 and the second light sensor 6, which is conducive to further improving the accuracy of the brightness synchronization test.

[0101] In some embodiments of the present application, Figure 2 As shown, the first camera 10 is arranged in the first subspace 1111, and the first camera 10 is arranged opposite to the instrument display screen 2, and the second camera 20 is arranged in the second subspace 1112, and the second camera 20 is arranged opposite to the vehicle display screen 3. In other words, the first camera 10 and the second camera 20 are respectively arranged in an independent space, the first camera 10 is used to detect the display image of the instrument display screen 2 in the first subspace 1111, and the second camera 20 is used to detect the display image of the vehicle display screen 3 in the second subspace 1112. Such an arrangement can avoid the mutual influence of the images obtained by the first camera 10 and the second camera 20, which is conducive to improving the accuracy of the gear simulation.

The mechanical arm 9 clicks or slides the brightness synchronization virtual button of the vehicle display screen 3 to generate a brightness synchronization request signal at different brightness levels. The CAN control module 8 is used to control the instrument display screen 2 and the vehicle display screen 3 to synchronize brightness according to the brightness synchronization request signal. For example, by clicking the brightness synchronization virtual button to enter the brightness synchronization setting interface of the vehicle display screen 3, then turn on the brightness synchronization function by clicking, and set the brightness level value by sliding. At this time, the screen brightness of the vehicle display screen 3 and the instrument display screen 2 begins to synchronize.

[0106] S204, the CAN control module 8 executes the light simulation signal or the gear simulation signal. S204 is performed synchronously with S203. When the CAN control module 8 sends the light simulation signal, the CAN control module 8 controls the instrument display screen 2 to display the light simulation icon according to the light simulation signal. When the CAN control module 8 sends the gear simulation signal, the CAN control module 8 controls the instrument display screen 2 to display the gear simulation icon according to the gear simulation signal, and controls the vehicle display screen 3 to display the simulated image around the vehicle, so as to increase the brightness synchronization performance of the vehicle display screen 3 and the instrument display screen 2 under different vehicle operating conditions.

[0107] 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 brightness of the instrument display screen 2 after brightness synchronization, and the second light sensor 6 is used to collect the second light brightness of the instrument display screen 2 after brightness synchronization.
