[0002] As the space inside the vehicle gradually becomes larger, a single ceiling screen can no longer meet the entertainment needs of passengers.

[0003] In view of this, how to flexibly adjust the image quality of multiple ceiling screens has become a technical problem that needs to be solved urgently. Summary of the invention

[0020] In order to make the objectives, technical solutions and advantages of the present disclosure more clearly understood, the present disclosure is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0021] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present disclosure should be understood by people with ordinary skills in the field to which the present disclosure belongs. The "first", "second" and similar words used in the embodiments of the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. "Including" or "comprising" and similar words mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0022] Based on the description of the background technology, with the development of vehicle technology, the functions of the in-car entertainment system are becoming more and more abundant, especially the entertainment facilities for rear passengers, such as single ceiling screen and double ceiling screen.

[0023] A single ceiling screen is a screen installed in the middle of the rear roof for rear-seat entertainment. However, as the number of rear seats in vehicle design increases, the rear space gradually becomes larger, and there are more and more rear passengers with different viewing needs. Therefore, a single ceiling screen can no longer meet the traditional rear-seat entertainment needs.

[0024] At present, the rear dual ceiling screen has become a higher-end rear entertainment method that major car companies are competing to develop and design. The rear dual ceiling screen is to install the left and right ceiling screens on the left and right sides of the rear roof for rear entertainment. Under normal circumstances, the image quality of the left and right rear ceiling screens is in a collaborative relationship, because these two ceiling screens are both rear entertainment screens and are both located on the roof. That is, if the image quality of any of the two ceiling screens is changed, the other ceiling screen will also be changed accordingly, avoiding the rear passengers having to change the screen image quality twice. This saves the time of changing them separately, directly realizes image quality collaboration, and can ensure the consistency of the visual effect of the rear viewing. Although the automatic coordination of the image quality of the two ceiling screens can ensure a consistent display effect in the back row, for example, the horizontal direction of the car is very wide, that is, the horizontal spacing between the two ceiling screens is far. In theory, the necessity for the two ceiling screens to coordinate their image quality is low. At this time, the left and right passengers in the back row have different requirements for image quality. For example, the image quality of the left ceiling screen in the back row can be increased by voice active control, and the image quality of the right ceiling screen in the back row can be decreased by voice active control. If the image quality of the two ceiling screens is forced to coordinate directly, it will not meet the subjective needs of multiple different passengers in the back row. In another case, for example, the horizontal direction of the car is very narrow, that is, the horizontal spacing between the two ceiling screens is very close. In theory, the necessity for the two ceiling screens to coordinate their image quality is high. Otherwise, in the narrow space, it is easy for the rear passengers to see the two ceiling screens at the same time within their field of vision. At this time, if the image quality of the two ceiling screens is not coordinated, it is easy to cause visual discomfort.

[0025] In summary, when a vehicle is installed with a dual ceiling screen in the rear row, since these two ceiling screens are installed on the roof and are in different horizontal positions laterally, the horizontal distance between the two ceiling screens is dependent on the rear passengers' need for coordinated image quality of the two ceiling screens. Therefore, the disclosed embodiment needs to design a more reasonable method for intelligent coordination of the display effects of the dual ceiling screens in the rear row to solve the above problems.

[0026] As mentioned above, how to flexibly adjust the image quality of multiple ceiling screens has become an important research issue.

[0027] Based on the above description, if Figure 1 As shown, the control method of the vehicle screen proposed in this embodiment, the vehicle screen includes: at least two ceiling screens; the method includes:

[0028] Step 101, receiving an image quality adjustment instruction of a vehicle ceiling screen, and obtaining a horizontal distance between two ceiling screens.

[0029] During specific implementation, the image quality adjustment instruction is an instruction for adjusting the image quality of any one of the at least two ceiling screens.

[0030] After receiving the image quality adjustment instruction of any ceiling screen in the vehicle, in order to determine whether the two ceiling screens need to be controlled in linkage, the horizontal distance between the two ceiling screens is obtained, so as to determine whether the other ceiling screen needs to be controlled in linkage based on the horizontal distance between the two ceiling screens.

[0031] For example, the at least two ceiling screens include: a first ceiling screen and a second ceiling screen. Upon receiving the image quality adjustment instruction of the first ceiling screen, the horizontal distance between the first ceiling screen and the second ceiling screen is obtained, so as to determine whether linkage control of the second ceiling screen is required based on the horizontal distance.

[0032] Step 102: determining a control method of the two ceiling screens according to the horizontal distance, and adjusting the image quality of the two ceiling screens according to the control method based on the image quality adjustment instruction.

[0033] In specific implementation, when the horizontal distance between the two ceiling screens is small, it means that the two ceiling screens are close to each other, and the probability that the passenger can see the two ceiling screens at the same time is very high. In order to avoid visual discomfort caused by passengers watching two ceiling screens with different picture qualities at the same time, the control mode of the two ceiling screens is determined to be a synchronous control mode, and the two ceiling screens are controlled in linkage, and the two ceiling screens are controlled to adjust the picture quality at the same time based on the picture quality adjustment instruction.

[0034] When the horizontal distance between the two ceiling screens is large, it means that the two ceiling screens are far apart, and the probability of passengers viewing the two ceiling screens at the same time is very low. In order to meet the different image quality requirements of multiple passengers for the two ceiling screens, the control mode of the two ceiling screens is determined to be an asynchronous control mode, and the two ceiling screens are controlled separately, and the corresponding ceiling screens are controlled to adjust the image quality based on the image quality adjustment instruction.

[0035] Through the above embodiments, at least two ceiling screens are provided on the vehicle. An image quality adjustment instruction of the vehicle ceiling screen is received, and the horizontal distance between the two ceiling screens is obtained. The control mode of the two ceiling screens is determined according to the horizontal distance, and the image quality of the two ceiling screens is adjusted according to the control mode based on the image quality adjustment instruction. In this way, according to the horizontal distance between the two ceiling screens, the control mode of the two ceiling screens can be accurately determined, so that the image quality of the two ceiling screens can be flexibly adjusted based on the horizontal distance between the two ceiling screens, avoiding the situation where the image quality of multiple ceiling screens is directly adjusted synchronously, which cannot meet the needs of passengers, and improving the passenger experience.

[0036] In some embodiments, step 102 includes:

[0037] Step 1021, comparing the horizontal distance with a preset distance threshold.

[0038] Step 1022, in response to determining that the horizontal distance is less than or equal to a preset distance threshold, determining that the control mode of the two ceiling screens is a synchronous control mode, and adjusting the image quality of the two ceiling screens according to the synchronous control mode based on the image quality adjustment instruction.

[0039] Step 1023, in response to determining that the horizontal distance is greater than a preset distance threshold, determining that the control mode of the two ceiling screens is an asynchronous control mode, and adjusting the image quality of the two ceiling screens according to the asynchronous control mode based on the image quality adjustment instruction.

[0040] In specific implementation, the preset distance threshold is a preset distance boundary value at which the passenger's field of vision can simultaneously view two ceiling screens. The horizontal distance is compared with the preset distance threshold to obtain a distance judgment result, so as to determine whether the passenger's field of vision can simultaneously view the two ceiling screens according to the distance judgment result.

[0041] For example, the horizontal distance between the two ceiling screens is represented as X, and the preset distance threshold is represented as X'. When the horizontal distance between the two ceiling screens is less than or equal to the preset distance threshold (X≤X'), the passenger can see the two ceiling screens at the same time, and the control mode of the two ceiling screens is determined to be a synchronous control mode, and the image quality of the two ceiling screens is adjusted in linkage, and the two ceiling screens are controlled to adjust the image quality based on the image quality adjustment instruction. In this way, the problem of passengers' visual experience being affected by different image quality when they watch two ceiling screens at the same time can be avoided.

[0042] When the horizontal distance between the two ceiling screens is greater than the preset distance threshold (X>X'), the passenger's field of vision cannot see the two ceiling screens at the same time, and the control mode of the two ceiling screens is determined to be an asynchronous control mode, and the image quality of the two ceiling screens is adjusted separately, and the corresponding ceiling screens are controlled to adjust the image quality based on the image quality adjustment instruction. In this way, the different image quality requirements of multiple passengers for the two ceiling screens can be met.

[0043] The ceiling screen may be a rear-row ceiling screen. When the ceiling screen is a rear-row ceiling screen, at least two ceiling screens include: a left-side rear-row ceiling screen and a right-side rear-row ceiling screen. Specifically, the horizontal distance between the left-side rear-row ceiling screen and the right-side rear-row ceiling screen is obtained. When X≤X', it is determined that the control mode of the left-side rear-row ceiling screen and the right-side rear-row ceiling screen is a synchronous control mode, and based on the image quality adjustment instruction, the left-side rear-row ceiling screen and the right-side rear-row ceiling screen are simultaneously controlled to adjust the image quality. When X>X', it is determined that the control mode of the left-side rear-row ceiling screen and the right-side rear-row ceiling screen is an asynchronous control mode, and based on the image quality adjustment instruction, the left-side rear-row ceiling screen and the right-side rear-row ceiling screen are respectively controlled to adjust the image quality.

[0044] In some scenarios, the preset distance threshold includes: a first distance threshold X1 and a second distance threshold X2, wherein the first distance threshold X1 is a lower distance limit, and the second distance threshold X2 is an upper distance limit.

[0045] When the horizontal distance between the two ceiling screens is less than the preset first distance threshold (X<X1), the control mode of the two ceiling screens is determined to be a synchronous control mode, and the image quality of the two ceiling screens is adjusted in the synchronous control mode based on the image quality adjustment instruction. When the horizontal distance between the two ceiling screens is greater than the preset second distance threshold (X>X2), the control mode of the two ceiling screens is determined to be an asynchronous control mode, and the image quality of the two ceiling screens is adjusted in the asynchronous control mode based on the image quality adjustment instruction.

[0046] When the horizontal distance between the two ceiling screens is greater than or equal to the preset first distance threshold and less than or equal to the second distance threshold (X1≤X≤X2), the image quality of the two ceiling screens is adjusted according to the preset control method based on the image quality adjustment instruction. The preset control method is a control method pre-set by the passenger, and the passenger can customize the preset control method. For example, when the preset control method is a synchronous control method, when X1≤X≤X2, the image quality of the two ceiling screens is adjusted according to the synchronous control method based on the image quality adjustment instruction. For another example, when the preset control method is an asynchronous control method, when X1≤X≤X2, the image quality of the two ceiling screens is adjusted according to the asynchronous control method based on the image quality adjustment instruction.

[0047] Through the above scheme, when the horizontal distance between the two ceiling screens is less than or equal to the preset distance threshold, the image quality of the two ceiling screens is adjusted in a synchronous control manner based on the image quality adjustment instruction. By adjusting the image quality of the two ceiling screens in linkage, it is possible to avoid the problem of passengers' visual experience being affected by different image quality when they watch the two ceiling screens at the same time. When the horizontal distance between the two ceiling screens is greater than the preset distance threshold, the image quality of the two ceiling screens is adjusted in an asynchronous control manner based on the image quality adjustment instruction. By adjusting the image quality of the two ceiling screens separately, it is possible to meet the different image quality requirements of multiple passengers for the two ceiling screens.

[0048] In some embodiments, the two ceiling screens include: a first ceiling screen and a second ceiling screen; step 1023 includes:

[0049] Step 1023A, determining the target control screen corresponding to the image quality adjustment instruction.

[0050] Step 1023B, in response to determining that the target control screen is the first ceiling screen, controlling the first ceiling screen to adjust the image quality based on the image quality adjustment instruction, and controlling the second ceiling screen to maintain the image quality.

[0051] Step 1023C, in response to determining that the target control screen is the second ceiling screen, controlling the second ceiling screen to adjust the image quality based on the image quality adjustment instruction, and controlling the first ceiling screen to maintain the image quality.

[0052] In a specific implementation, when the horizontal distance between the two ceiling screens is greater than a preset distance threshold, the two ceiling screens are controlled separately, and the corresponding ceiling screens are controlled to adjust the image quality based on the image quality adjustment instruction. In this scenario, the target control screen corresponding to the image quality adjustment instruction is determined, and the target control screen is controlled based on the image quality adjustment instruction.

[0053] Specifically, when the horizontal distance between the two ceiling screens is greater than a preset distance threshold, the target control screen corresponding to the image quality adjustment instruction is determined. When the target control screen is the first ceiling screen, the first ceiling screen is controlled to adjust the image quality based on the image quality adjustment instruction, and the second ceiling screen is controlled to maintain the image quality, that is, the second ceiling screen is not controlled to adjust the image quality. When the target control screen is the second ceiling screen, the second ceiling screen is controlled to adjust the image quality based on the image quality adjustment instruction, and the first ceiling screen is controlled to maintain the image quality, that is, the first ceiling screen is not controlled to adjust the image quality.

[0054] The ceiling screen may be a rear-row ceiling screen. When the ceiling screen is a rear-row ceiling screen, the at least two ceiling screens include: a left rear-row ceiling screen and a right rear-row ceiling screen.

[0055] When the horizontal distance between the two ceiling screens is greater than a preset distance threshold, the target control screen corresponding to the image quality adjustment instruction is determined. When the target control screen is the left rear ceiling screen, the left rear ceiling screen is controlled to adjust the image quality based on the image quality adjustment instruction, and the right rear ceiling screen is controlled to maintain the image quality, that is, the right rear ceiling screen is not controlled to adjust the image quality. When the target control screen is the right rear ceiling screen, the right rear ceiling screen is controlled to adjust the image quality based on the image quality adjustment instruction, and the left rear ceiling screen is controlled to maintain the image quality, that is, the left rear ceiling screen is not controlled to adjust the image quality.

[0056] Through the above scheme, in the process of adjusting the image quality of the two ceiling screens separately, when the target control screen corresponding to the image quality adjustment instruction is the first ceiling screen, the first ceiling screen is controlled to adjust the image quality based on the image quality adjustment instruction, and the second ceiling screen is controlled to maintain the image quality. When the target control screen corresponding to the image quality adjustment instruction is the second ceiling screen, the second ceiling screen is controlled to adjust the image quality based on the image quality adjustment instruction, and the first ceiling screen is controlled to maintain the image quality. In this way, when adjusting the image quality of the two ceiling screens separately, the image quality of the target control screen corresponding to the image quality adjustment instruction can be accurately adjusted to avoid affecting the image quality of other screens.

[0057] In some embodiments, after step 1022, the method further includes:

[0058] Step 1022A, receiving an image quality restoration instruction of any one of the two ceiling screens, and providing an image quality difference prompt.

[0059] Step 1022B, after the image quality difference prompt, a recovery instruction is received to control any of the ceiling screens to recover to the image quality before adjustment.

[0060] During specific implementation, the image quality restoration instruction is an instruction for restoring the image quality of any one of the two ceiling screens.

[0061] After the two ceiling screens are simultaneously controlled to adjust the picture quality based on the picture quality adjustment instruction, when a picture quality recovery instruction is received for any of the two ceiling screens, indicating that the passenger does not want to synchronously adjust the picture quality of either ceiling screen, in order to avoid the visual discomfort of the passengers when watching the two ceiling screens when the picture qualities of the two ceiling screens are different, a picture quality difference prompt is made. Through the picture quality difference prompt, the passengers can be explained the disadvantage of the picture quality difference of the two ceiling screens affecting the visual effect.

[0062] Receiving a confirmation recovery instruction after the image quality difference prompt indicates that the passenger has decided not to synchronously adjust the image quality of any ceiling screen. In order to satisfy the passengers' good experience when watching the ceiling screen, any ceiling screen is controlled to restore to the image quality before adjustment.

[0063] The ceiling screen may be a rear-row ceiling screen. When the ceiling screen is a rear-row ceiling screen, the at least two ceiling screens include: a left-side rear-row ceiling screen and a right-side rear-row ceiling screen. For example, a picture quality adjustment instruction is received for the left-side rear-row ceiling screen, and when the horizontal distance between the two ceiling screens is less than or equal to a preset distance threshold, the left-side rear-row ceiling screen and the right-side rear-row ceiling screen are controlled to simultaneously adjust the picture quality based on the picture quality adjustment instruction. After the picture quality adjustment, a picture quality restoration instruction is received for the right-side rear-row ceiling screen, and a picture quality difference prompt is given. After the picture quality difference prompt, a confirmation restoration instruction is received, and the right-side rear-row ceiling screen is controlled to restore to the picture quality before adjustment.

[0064] Through the above scheme, after the image quality of the two ceiling screens is adjusted in linkage, an image quality restoration instruction of any of the two ceiling screens is received, and a picture quality difference prompt is given. By giving a picture quality difference prompt, the disadvantage of the difference in image quality of the two ceiling screens affecting the visual effect can be explained to the passengers, and the visual impact of the difference in image quality of the two ceiling screens on the passengers when watching the ceiling screens can be avoided to the greatest extent. After the picture quality difference prompt, a confirmation restoration instruction is received, and any ceiling screen is controlled to restore to the picture quality before adjustment. In this way, when passengers have different requirements for the picture quality of the two ceiling screens, by restoring any ceiling screen to the picture quality before adjustment, the different requirements of passengers for the picture quality of the ceiling screens can be met, ensuring a good experience for passengers when watching the ceiling screens.

[0065] In some embodiments, the two ceiling screens include: a first ceiling screen and a second ceiling screen; the image quality adjustment instruction includes: a first image quality adjustment instruction for the first screen and a second image quality adjustment instruction for the second screen; after step 101, it also includes:

[0066] Step 101A: determine the difference between the first image quality adjustment instruction and the second image quality adjustment instruction, and compare the difference with a preset difference threshold.

[0067] Step 101B, in response to determining that the degree of difference is less than a preset difference threshold, controlling the first ceiling screen to adjust image quality based on the first image quality adjustment instruction, and controlling the second ceiling screen to adjust image quality based on the second image quality adjustment instruction.

[0068] Step 101C, in response to determining that the degree of difference is greater than or equal to a preset difference threshold, a picture quality difference prompt is given, and an adjustment instruction is received after the picture quality difference prompt, and the first ceiling screen is controlled to adjust the picture quality based on the first picture quality adjustment instruction, and the second ceiling screen is controlled to adjust the picture quality based on the second picture quality adjustment instruction.

[0069] In a specific implementation, the first image quality adjustment instruction is an instruction for adjusting the image quality of the first ceiling screen, and the second image quality adjustment instruction is an instruction for adjusting the image quality of the second ceiling screen.

[0070] When adjusting the image quality of the first ceiling screen and the second ceiling screen, judging the degree of difference between the first image quality adjustment instruction and the second image quality adjustment instruction can determine whether there will be a large difference in image quality between the first ceiling screen and the second ceiling screen after adjusting the image quality, affecting the passengers' visual experience.

[0071] When the difference is less than the preset difference threshold, it means that after the image quality of the first ceiling screen and the second ceiling screen is adjusted, there will be no problem of large image quality difference affecting the visual experience of passengers. In this scenario, the image quality of the first ceiling screen and the second ceiling screen are directly adjusted respectively, the first ceiling screen is controlled to adjust the image quality based on the first image quality adjustment instruction, and the second ceiling screen is controlled to adjust the image quality based on the second image quality adjustment instruction.

[0072] For example, a rear passenger issues a voice command "Raise the left rear ceiling screen to 35% brightness, and lower the right rear ceiling screen to 30% brightness". That is, the first image quality adjustment command is "35% brightness of the left rear ceiling screen", and the second image quality adjustment command is "lower the right rear ceiling screen to 35% brightness". In this scenario, the difference between the first adjustment command and the second adjustment command is small, and the left rear ceiling screen is directly adjusted to 35% brightness, and the right rear ceiling screen is adjusted to 30% brightness.

[0073] When the difference is greater than or equal to the preset difference threshold, it means that after the picture quality of the first ceiling screen and the second ceiling screen is adjusted, there will be a large difference in picture quality that affects the visual experience of passengers. In this scenario, a picture quality difference prompt is first given, and after the picture quality difference prompt is received, a confirmation adjustment instruction is received, and then the picture quality of the first ceiling screen and the second ceiling screen are adjusted respectively.

[0074] For example, a rear passenger issues a voice command "Raise the left rear ceiling screen to 90% brightness, and lower the right rear ceiling screen to 30% brightness". That is, the first image quality adjustment command is "90% brightness of the left rear ceiling screen", and the second image quality adjustment command is "lower the right rear ceiling screen to 35% brightness". In this scenario, the difference between the first adjustment command and the second adjustment command is relatively large, and the image quality difference prompt is performed first. After the image quality difference prompt, the confirmation adjustment command is received, and then the left rear ceiling screen is adjusted to 35% brightness, and the right rear ceiling screen is adjusted to 30% brightness.

[0075] Through the above scheme, when a first picture quality adjustment instruction of the first screen and a second picture quality adjustment instruction of the second screen are received, the difference between the first picture quality adjustment instruction and the second picture quality adjustment instruction is determined. When the difference is less than a preset difference threshold, the first ceiling screen is directly controlled to adjust the picture quality based on the first picture quality adjustment instruction, and the second ceiling screen is controlled to adjust the picture quality based on the second picture quality adjustment instruction. In this way, when passengers watch the two ceiling screens at the same time, the picture quality requirements of different passengers for the first ceiling screen and the second ceiling screen can be met respectively without affecting the visual effects of the passengers. When the degree of difference is greater than or equal to a preset difference threshold, a picture quality difference prompt is first given. By giving the picture quality difference prompt, the passengers can be informed of the disadvantages of the picture quality difference between the two ceiling screens affecting the visual effect, and the visual impact on the passengers when watching the ceiling screens when the picture quality difference between the two ceiling screens is large can be avoided to the greatest extent. After the picture quality difference prompt, an adjustment instruction is received and confirmed, and then the first ceiling screen is controlled to adjust the picture quality based on the first picture quality adjustment instruction, and the second ceiling screen is controlled to adjust the picture quality based on the second picture quality adjustment instruction, thereby meeting the passengers' demands for the difference in picture quality of the ceiling screens and ensuring a good experience for the passengers when watching the ceiling screens.

[0076] In some embodiments, the ceiling screen is a rear ceiling screen; after step 101, the method further includes:

[0077] Step 1011, determine whether there is a passenger in the middle position of the rear seat, and obtain a determination result.

[0078] Step 1012, determining a control method for the two rear ceiling screens according to the horizontal distance and the judgment result, and adjusting the image quality of the two rear ceiling screens according to the control method based on the image quality adjustment instruction.

[0079] In a specific implementation, when the ceiling screen is a rear-row ceiling screen, the at least two ceiling screens include: a left rear-row ceiling screen and a right rear-row ceiling screen.

[0080] Figure 2 FIG. 1 is a schematic diagram of the linkage control of two rear ceiling screens in an embodiment of the present disclosure. Figure 2 As shown, in general, the left rear passenger watches the left rear ceiling screen, the right rear passenger watches the right rear ceiling screen, and the middle rear passenger may watch the left and right rear ceiling screens at the same time. By judging whether there is a passenger in the middle position of the rear seat, it can be determined whether there is a situation where a passenger watches two rear ceiling screens at the same time.

[0081] By comparing the horizontal distance between the two rear-row ceiling screens with the preset distance threshold and judging whether there is a passenger in the middle of the rear seats, it is possible to accurately judge whether the different image qualities of the two rear-row ceiling screens will cause visual discomfort to the passengers. When the different image qualities of the two rear-row ceiling screens will cause visual discomfort to the passengers, the two rear-row ceiling screens will be controlled in conjunction. When the different image qualities of the two rear-row ceiling screens will not cause visual discomfort to the passengers, the two rear-row ceiling screens will be controlled separately.

[0082] Through the above scheme, according to the horizontal distance between the two rear ceiling screens and whether there are passengers in the middle position of the rear seats, it is possible to accurately judge whether the different picture quality of the two rear ceiling screens will cause visual discomfort to the passengers, thereby more accurately determining the control method of the two rear ceiling screens, and adjusting the picture quality of the two rear ceiling screens according to the control method based on the picture quality adjustment instruction.

[0083] In some embodiments, step 1012 includes:

[0084] Step 1012A, in response to determining that the horizontal distance is less than or equal to a preset distance threshold or the judgment result is that there is a passenger in the middle position of the rear seat, determine that the control mode of the two rear ceiling screens is a synchronous control mode.

[0085] Step 1012B, in response to determining that the horizontal distance is greater than a preset distance threshold and the judgment result is that there is no passenger in the middle position of the rear seat, determine that the control mode of the two rear ceiling screens is an asynchronous control mode.

[0086] In specific implementation, when the horizontal distance between the two rear-row ceiling screens is less than or equal to the preset distance threshold or there is a passenger in the middle of the rear seat, the rear passenger is more likely to watch the two rear-row ceiling screens at the same time. When the image quality of the two rear-row ceiling screens is different, there will be visual discomfort for the passengers. In order to avoid visual discomfort when passengers watch the two rear-row ceiling screens at the same time, the control mode of the two rear-row ceiling screens is determined to be a synchronous control mode, and the image quality of the two rear-row ceiling screens is adjusted in linkage. Based on the image quality adjustment instruction, the left rear-row ceiling screen and the right rear-row ceiling screen are simultaneously controlled to adjust the image quality.

[0087] When the horizontal distance between the two rear ceiling screens is greater than the preset distance threshold and there is no passenger in the middle of the rear seats, the probability of the rear passengers watching the two rear ceiling screens at the same time is low, and there will be no visual discomfort for the passengers when the two rear ceiling screens have different picture qualities. In order to meet the different picture quality requirements of multiple passengers for the two rear ceiling screens, the control mode of the two rear ceiling screens is determined to be an asynchronous control mode, and the picture quality of the two rear ceiling screens is adjusted separately, and the corresponding rear ceiling screens are controlled to adjust the picture quality based on the picture quality adjustment instruction.

[0088] Through the above scheme, when the horizontal distance between the two ceiling screens is less than or equal to the preset distance threshold or there is a passenger in the middle position of the rear seat, the control mode of the two rear ceiling screens is determined to be a synchronous control mode, and the image quality of the two rear ceiling screens is adjusted in linkage, which can avoid the problem of visual discomfort when passengers watch the two rear ceiling screens at the same time. When the horizontal distance between the two ceiling screens is greater than the preset distance threshold and there is no passenger in the middle position of the rear seat, the control mode of the two rear ceiling screens is determined to be an asynchronous control mode, and the image quality of the two rear ceiling screens is adjusted separately, which can meet the different image quality requirements of multiple passengers for the two rear ceiling screens.

[0089] Through the above embodiments, at least two ceiling screens are provided on the vehicle. An image quality adjustment instruction of the vehicle ceiling screen is received, and the horizontal distance between the two ceiling screens is obtained. The control mode of the two ceiling screens is determined according to the horizontal distance, and the image quality of the two ceiling screens is adjusted according to the control mode based on the image quality adjustment instruction. In this way, according to the horizontal distance between the two ceiling screens, the control mode of the two ceiling screens can be accurately determined, so that the image quality of the two ceiling screens can be flexibly adjusted based on the horizontal distance between the two ceiling screens, avoiding the situation where the image quality of multiple ceiling screens is directly adjusted synchronously, which cannot meet the needs of passengers, and improving the passenger experience.

[0090] This embodiment also proposes a method for controlling a vehicle screen, wherein the vehicle screen includes: a ceiling screen being displayed, and a roof light is arranged on the top of the vehicle; the method includes:

[0091] Step 201, obtaining the state of the roof light, and determining whether the state of the roof light is on.

[0092] During specific implementation, the state of the roof light is obtained, and by judging whether the state of the roof light is on, it is possible to accurately judge whether the roof light has an impact on the image quality of the ceiling screen.

[0093] The roof light is a light-emitting device arranged on the top of the vehicle. Among them, the roof light includes a ceiling light, an illumination light and a starry sky ceiling. The roof light in the embodiment of the present disclosure is preferably a starry sky ceiling.

[0094] Step 202, in response to determining that the state of the ceiling light is on, obtaining lighting parameters of the ceiling light, determining a lighting area of ​​the ceiling light based on the lighting parameters, and determining whether the lighting area is within a preset area.

[0095] In specific implementation, when the roof light is on, it can be determined that the roof light has an impact on the image quality of the ceiling screen. In order to further determine whether the roof light has a significant impact on the image quality of the ceiling screen, the lighting parameters of the roof light are obtained, and the lighting area of ​​the roof light is determined based on the lighting parameters of the roof light. By determining whether the lighting area of ​​the roof light is within the preset area, it can be accurately determined whether the roof light has a significant impact on the image quality of the ceiling screen.

[0096] Among them, the preset area range is the roof light lighting area that can have a greater impact on the picture quality of the ceiling screen.

[0097] Step 203, in response to determining that the lighting area is within a preset area, determining that the ceiling light has image quality interference on the ceiling screen, and adjusting the image quality of the ceiling screen according to the lighting parameters.

[0098] When it comes to specific implementation, Figure 3 Schematic diagram of the safety threshold of the lighting area of ​​the starry sky top in the embodiment of the present disclosure. Figure 3 As shown, a ceiling screen is set on the roof, and there is a lighting area safety threshold (i.e., a preset area range) around the ceiling screen. When the lighting area of ​​the ceiling light is within the lighting area safety threshold (i.e., a preset area range), the ceiling light will interfere with the image quality of the ceiling screen. When the lighting area of ​​the ceiling light is not within the lighting area safety threshold (i.e., a preset area range), the ceiling light will not interfere with the image quality of the ceiling screen.

[0099] When the lighting area of ​​the roof light is within the preset area, it can be accurately determined that the roof light has a significant impact on the image quality of the ceiling screen, that is, the roof light interferes with the image quality of the ceiling screen. After determining that the headlight interferes with the image quality of the ceiling screen, the image quality of the ceiling screen is adjusted according to the lighting parameters of the roof light, so that the ceiling screen can achieve the image quality before the interference in terms of visual perception.

[0100] In some scenarios, the ceiling screen synchronizes image quality with other screens in the vehicle. When the ceiling light interferes with the image quality of the ceiling screen, the user may feel that the image quality of the ceiling screen is inconsistent with that of other screens. The image quality of the ceiling screen is adjusted according to the lighting parameters of the ceiling light, so that the user may feel that the image quality of the ceiling screen is consistent with that of other screens.

[0101] When the roof light is a starry sky ceiling, the image quality of the ceiling screen is adjusted based on the starry sky ceiling. The specific process includes: obtaining the state of the starry sky ceiling, and judging whether the starry sky ceiling state is on, so as to judge whether the starry sky ceiling has an impact on the image quality of the ceiling screen. When the starry sky ceiling state is on, the lighting parameters of the starry sky ceiling are obtained, the lighting area of ​​the starry sky ceiling is determined based on the lighting parameters, and it is judged whether the lighting area is within the preset area, so as to further judge whether the starry sky ceiling has a greater impact on the image quality of the ceiling screen. When the lighting area of ​​the starry sky ceiling is within the preset area, it means that the starry sky ceiling interferes with the image quality of the ceiling screen, and the image quality of the ceiling screen is adjusted according to the lighting parameters of the starry sky ceiling.

[0102] Through the above embodiment, the vehicle screen includes: a ceiling screen being displayed, and a ceiling light is arranged on the top of the vehicle. The state of the ceiling light is obtained, and it is determined whether the state of the ceiling light is on. When the state of the ceiling light is on, the lighting parameters of the ceiling light are obtained, the lighting area of ​​the ceiling light is determined based on the lighting parameters, and it is determined whether the lighting area is within the preset area. When the lighting area is within the preset area, it is determined that the ceiling light has image quality interference on the ceiling screen, and the image quality of the ceiling screen is adjusted according to the lighting parameters. In this way, when the ceiling light is on and the lighting area is within the preset range, it can be accurately determined that the ceiling light has image quality interference on the ceiling screen, and the image quality of the ceiling screen is adjusted according to the lighting parameters of the ceiling light, so that the ceiling screen can achieve the image quality before the interference in terms of visual perception, thereby ensuring the user experience when watching the ceiling screen.

[0103] In some embodiments, step 203 includes:

[0104] Step 2031, obtaining the current brightness of the ceiling screen at the current moment.

[0105] Step 2032: determine the brightness of the ceiling light based on the lighting parameter, and compare the brightness of the ceiling light with a preset brightness threshold.

[0106] Step 2033, in response to determining that the brightness of the roof light is greater than a preset brightness threshold, controlling the ceiling screen to adjust from the current brightness to the target brightness according to the brightness of the roof light.

[0107] In specific implementation, the brightness of the roof light is determined based on the lighting parameters of the roof light. When the brightness of the roof light is greater than a preset brightness threshold, it indicates that the roof light interferes with the brightness of the ceiling screen and the brightness of the ceiling screen needs to be compensated.

[0108] The target brightness of the ceiling screen after compensation is determined based on the brightness of the roof lights, and the ceiling screen is controlled to adjust from the current brightness to the target brightness, so that the ceiling screen can reach the brightness before interference in terms of visual perception.

[0109] In some scenarios, the ceiling screen synchronizes image quality with other screens in the vehicle. When the ceiling light interferes with the brightness of the ceiling screen, the user visually feels that the brightness of the ceiling screen is inconsistent with that of other screens. The ceiling screen is controlled to adjust from the current brightness to the target brightness according to the brightness of the ceiling light, so that the user visually feels that the brightness of the ceiling screen is consistent with that of other screens.

[0110] When the roof light is a starry sky ceiling, the brightness of the ceiling screen is adjusted based on the starry sky ceiling. The specific process includes: determining the brightness of the starry sky ceiling based on the lighting parameters of the starry sky ceiling. When the brightness of the starry sky ceiling is greater than the preset brightness threshold, the ceiling screen is controlled to adjust from the current brightness to the target brightness according to the brightness of the starry sky ceiling.

[0111] Through the above scheme, when the brightness of the roof light is greater than the preset brightness threshold, the ceiling screen is controlled to adjust from the current brightness to the target brightness according to the brightness of the roof light. In this way, when the roof light interferes with the brightness of the ceiling screen, the brightness of the ceiling screen is compensated according to the brightness of the roof light, so that the ceiling screen can reach the brightness before the interference in visual perception, thereby ensuring the user's experience when viewing the ceiling screen.

[0112] In some embodiments, step 2033 includes:

[0113] Step 20331, in response to determining that the brightness of the roof light is greater than a preset brightness threshold, determining an initial compensation brightness according to the brightness of the roof light.

[0114] Step 20332: Based on the lighting parameters, the initial compensation brightness is corrected to obtain the target compensation brightness.

[0115] Step 20333: sum the current brightness and the target compensation brightness to obtain the target brightness, and control the ceiling screen to adjust from the current brightness to the target brightness.

[0116] In a specific implementation, when controlling the ceiling screen to adjust from the current brightness to the target brightness, the target compensation brightness is determined based on the lighting parameters of the roof lights, and the brightness of the ceiling screen is compensated according to the target compensation brightness.

[0117] Specifically, the initial compensation brightness corresponding to the brightness of the roof light is determined according to the pre-stored correspondence. Based on the target distance between the light on the roof light and the ceiling screen and the target number of lights on the roof light, the initial compensation brightness is corrected to obtain the target compensation brightness. The current brightness and the target compensation brightness are summed to obtain the target brightness, and the ceiling screen is controlled to adjust from the current brightness to the target brightness, so that the user visually feels that the ceiling screen is consistent with the brightness of other screens.

[0118] When the roof light is a starry sky roof, the brightness of the ceiling screen is compensated based on the starry sky roof. The specific process includes: determining the initial compensation brightness according to the brightness of the starry sky roof, and correcting the initial compensation brightness based on the lighting parameters of the starry sky roof to obtain the target compensation brightness. The current brightness of the ceiling screen and the target compensation brightness are summed to obtain the target brightness, and the ceiling screen is controlled to adjust from the current brightness to the target brightness.

[0119] Through the above scheme, the initial compensation brightness can be determined according to the brightness of the roof light, and the initial compensation brightness is corrected based on the lighting parameters of the roof light, so that the target compensation brightness is more accurate, and the target brightness of the ceiling screen after compensation can be more accurately determined according to the current brightness and the target compensation brightness. In this way, when compensating the brightness of the ceiling screen, the brightness of the roof light and other lighting parameters of the roof light can be comprehensively considered, so as to compensate the ceiling screen more accurately, so that the user can visually feel that the brightness of the ceiling screen is consistent with that of other screens.

[0120] In some embodiments, the brightness threshold includes: a first brightness threshold and a second brightness threshold; step 20331 includes:

[0121] Step 20331A, determining a brightness difference according to the brightness of the roof light and the current brightness, and determining a target brightness difference range to which the brightness difference belongs from a plurality of preset brightness difference ranges.

[0122] Step 20331B, in response to determining that the brightness of the roof light is greater than or equal to the first brightness threshold and less than or equal to the second brightness threshold, determine the first compensation brightness corresponding to the target brightness difference range according to a pre-stored first correspondence relationship, and use the first compensation brightness as the initial compensation brightness.

[0123] Step 20331C, in response to determining that the brightness of the roof light is greater than the second brightness threshold, determine the second compensation brightness corresponding to the target brightness difference range according to a pre-stored second correspondence relationship, and use the second compensation brightness as the initial compensation brightness; wherein the first compensation brightness is less than the second compensation brightness.

[0124] In specific implementation, the pre-stored correspondence is the correspondence between the brightness difference range and the compensation brightness. For example, the brightness difference range A corresponds to the compensation brightness a, the brightness difference range B corresponds to the compensation brightness b, and the brightness difference range C corresponds to the compensation brightness c.

[0125] Specifically, the brightness difference between the brightness of the roof lamp and the current brightness of the ceiling screen is determined, and the target brightness difference range to which the brightness difference belongs is determined. The initial compensation brightness corresponding to the target brightness difference range is determined according to a pre-stored corresponding relationship.

[0126] The brightness threshold includes: a first brightness threshold AA1 and a second brightness threshold AA2. Wherein, AA1<AA2. The brightness of the roof light (starry sky roof brightness) is represented as AA.

[0127] When AA1≤AA≤AA2, it means that the ceiling light has a relatively small interference on the brightness of the ceiling screen. The first compensation brightness corresponding to the target brightness difference range is determined according to the first corresponding relationship, and the first compensation brightness is used as the initial compensation brightness. When AA>AA2, it means that the ceiling light has a relatively large interference on the brightness of the ceiling screen. The second compensation brightness corresponding to the target brightness difference range is determined according to the second corresponding relationship, and the second compensation brightness is used as the initial compensation brightness. Among them, when the target brightness difference range is the same, the corresponding first compensation brightness is less than the second compensation brightness. In this way, the corresponding initial compensation brightness can be determined according to the degree of interference of the ceiling light on the brightness of the ceiling screen.

[0128] When the roof light is a starry sky roof, the initial compensation brightness of the ceiling screen is determined based on the starry sky roof. The specific process includes: determining the brightness difference between the brightness of the starry sky roof and the current brightness of the ceiling screen, and determining the target brightness difference range to which the brightness difference belongs. The initial compensation brightness corresponding to the target brightness difference range is determined according to a pre-stored corresponding relationship.

[0129] Specifically, when AA1 ≤ AA ≤ AA2, the initial compensation brightness corresponding to the target brightness difference range is determined according to the first correspondence. For example, when the target brightness difference range is within 5 cd / m² - 10 cd / m², the initial compensation brightness is 5 cd / m²; when the target brightness difference range is within 10 cd / m² - 20 cd / m², the initial compensation brightness is 10 cd / m²; when the target brightness difference range is above 20 cd / m², the initial compensation brightness is 12 cd / m²; when the target brightness difference range is within 0 cd / m² - 5 cd / m², the initial compensation brightness is 1 cd / m². Here, CC represents the target brightness, and BB represents the current brightness. The specific first correspondence is as follows: ① 5 cd / m² < AA2 - AA < 10 cd / m², then CC = BB + 5 cd / m²; ② 10 cd / m² < AA2 - AA < 20 cd / m², then CC = BB + 10 cd / m²; ③ AA2 - AA ≥ 20 cd / m², then CC = BB + 12 cd / m²; ④ 0 ≤ AA2 - AA < 5 cd / m², then CC = BB + 1 cd / m².

[0130] Specifically, when AA > AA2, the initial compensation brightness corresponding to the target brightness difference range is determined according to the second correspondence. For example, when the target brightness difference range is within 5 cd / m² - 10 cd / m², the initial compensation brightness is 7 cd / m²; when the target brightness difference range is within 10 cd / m² - 20 cd / m², the initial compensation brightness is 12 cd / m²; when the target brightness difference range is above 20 cd / m², the initial compensation brightness is 15 cd / m²; when the target brightness difference range is within 0 cd / m² - 5 cd / m², the initial compensation brightness is 2 cd / m². Here, CC represents the target brightness, and BB represents the current brightness. The specific second correspondence is as follows: ① 5 cd / m² < AA2 - AA < 10 cd / m², then CC = BB + 7 cd / m²; ② 10 cd / m² < AA2 - AA < 20 cd / m², then CC = BB + 12 cd / m²; ③ AA2 - AA ≥ 20 cd / m², then CC = BB + 15 cd / m²; ④ 0 ≤ AA2 - AA < 5 cd / m², then CC = BB + 2 cd / m².

[0131] Through the above scheme, the brightness difference between the brightness of the roof light and the current brightness of the ceiling screen is determined, and the target brightness difference range to which the brightness difference belongs is determined. According to the pre-stored correspondence, the initial compensation brightness corresponding to the target brightness difference range can be accurately determined. In addition, when the brightness of the roof light is greater than or equal to the first brightness threshold and less than or equal to the second brightness threshold, it means that the interference of the roof light on the brightness of the ceiling screen is relatively small, and the initial compensation brightness corresponding to the target brightness difference range is determined according to the pre-stored first correspondence. When the brightness of the roof light is greater than the second brightness threshold, it means that the interference of the roof light on the brightness of the ceiling screen is relatively large, and the initial compensation brightness corresponding to the target brightness difference range is determined according to the pre-stored second correspondence. In this way, the initial compensation brightness can be determined according to the degree of interference of the roof light on the brightness of the ceiling screen, so that the obtained initial compensation brightness is more accurate.

[0132] In some embodiments, step 20332 includes:

[0133] Step 20332A, determining a target distance between the lit light in the roof light and the ceiling screen based on the lighting parameters, and determining a first correction coefficient according to the target distance.

[0134] Step 20332B, determining a target number of lights to be lit in the roof light based on the lighting parameters, and determining a second correction coefficient according to the target number.

[0135] Step 20332C, summing the initial compensation brightness, the first correction coefficient and the second correction coefficient to obtain the target compensation brightness.

[0136] In a specific implementation, the target distance between the light of the ceiling lamp and the ceiling screen is determined based on the lighting parameters of the ceiling lamp, and the first correction coefficient corresponding to the target distance is determined according to the pre-stored third corresponding relationship, wherein the third corresponding relationship is the corresponding relationship between the distance and the correction coefficient.

[0137] The target number of lights to be lit in the roof lamp is determined based on the lighting parameters of the roof lamp, and the second correction coefficient corresponding to the target number is determined according to the pre-stored fourth corresponding relationship, wherein the fourth corresponding relationship is a corresponding relationship between the number and the correction coefficient.

[0138] The initial compensation brightness, the first correction coefficient, and the second correction coefficient are summed to obtain the target compensation brightness. In this way, based on the target distance between the lighted light in the ceiling light and the ceiling screen and the target number of the lighted lights in the ceiling light, the initial compensation brightness is corrected so that the target compensation brightness is more accurate.

[0139] When the roof light is a starry sky ceiling, the target compensation brightness of the ceiling screen is determined based on the starry sky ceiling. The specific process includes: determining a first correction coefficient based on the target distance between the lit LED lights in the starry sky ceiling and the ceiling screen, determining a second correction coefficient based on the target number of lit LED lights in the starry sky ceiling, and summing the initial compensation brightness, the first correction coefficient and the second correction coefficient to obtain the target compensation brightness.

[0140] Through the above scheme, the first correction coefficient is determined based on the target distance between the light on the ceiling light and the ceiling screen, and the second correction coefficient is determined based on the target number of the light on the ceiling light. Based on the target distance between the light on the ceiling light and the ceiling screen and the target number of the light on the ceiling light, the initial compensation brightness is corrected so that the target compensation brightness is more accurate.

[0141] In some embodiments, step 2033 includes:

[0142] Step 2033A, in response to determining that the brightness of the ceiling light is greater than a preset brightness threshold, dividing the ceiling screen into multiple screen areas, and determining the brightness interference parameter of the ceiling light on each screen area.

[0143] Step 2033B, determining whether the brightness interference parameters of multiple screen areas are consistent.

[0144] Step 2033C: in response to determining that the brightness interference parameters of the multiple screen areas are inconsistent, determining a target screen area and a corresponding target brightness interference parameter from the multiple screen areas.

[0145] Step 2033D: Determine the target compensation brightness of the target screen area based on the roof light brightness and the target brightness interference parameter.

[0146] Step 2033E: The current brightness and the target compensation brightness are summed to obtain the target brightness, and the target screen area of ​​the ceiling screen is controlled to adjust from the current brightness to the target brightness.

[0147] In specific implementation, when the ceiling light interferes with the brightness of the ceiling screen, the brightness interference may only occur in a part of the ceiling screen. Therefore, when the brightness of the ceiling screen is compensated according to the brightness of the ceiling light, the brightness of the ceiling screen may be compensated in different areas.

[0148] Specifically, the ceiling screen is divided into multiple screen areas, and the brightness interference parameter of the ceiling light on each screen area is determined. When the brightness interference parameters of multiple screen areas are inconsistent, it is determined that the degree of brightness interference of the ceiling light on each area of ​​the ceiling screen is different. In addition, it is determined whether the target area of ​​the lighting light of the ceiling light is uniform. When the target area is not uniform, it is determined that the degree of brightness interference of the ceiling light on each area of ​​the ceiling screen is different.

[0149] When performing zone compensation for the brightness of the ceiling screen, determine the target screen area where the ceiling light has brightness interference on the ceiling screen, and determine the target compensation brightness of the target screen area. The current brightness of the ceiling screen and the target compensation brightness are summed to obtain the target brightness, and control the target screen area of ​​the ceiling screen to adjust from the current brightness to the target brightness.

[0150] When the roof light is a starry sky roof, the brightness of the ceiling screen is zoned and compensated based on the starry sky roof. The specific process includes: judging whether the LED lights at the top of the starry sky are evenly distributed around the ceiling screen. When the LED lights at the top of the starry sky are uneven, the target screen area with brightness interference in the ceiling screen is determined, and the target compensation brightness of the target screen area is determined. The current brightness of the ceiling screen and the target compensation brightness are summed to obtain the target brightness, and the target screen area of ​​the ceiling screen is controlled to adjust from the current brightness to the target brightness.

[0151] For example, the brightest LED light at the top of the starry sky is on the left side of the ceiling screen, and the left area of ​​the ceiling screen with brightness interference is determined, and the target compensation brightness of the left area is determined. The current brightness of the ceiling screen and the target compensation brightness are summed to obtain the target brightness, and the left area of ​​the ceiling screen is controlled to adjust from the current brightness to the target brightness.

[0152] Through the above scheme, when the brightness interference parameters of multiple screen areas of the ceiling screen are inconsistent, the target screen area with brightness interference in the ceiling screen is determined, and the target compensation brightness of the target screen area is determined. The current brightness of the ceiling screen and the target compensation brightness are summed to obtain the target brightness, and the target screen area of ​​the ceiling screen is controlled to adjust from the current brightness to the target brightness. In this way, by performing partition compensation on the brightness of the ceiling screen, the brightness of the target screen area with brightness interference in the ceiling screen can be accurately compensated, so that the user visually feels that the brightness of the ceiling screen is consistent with that of other screens.

[0153] In some embodiments, step 203 includes:

[0154] Step 203A, obtaining the current color temperature of the ceiling screen at the current moment.

[0155] Step 203B, determining the color temperature of the ceiling light based on the lighting parameters, determining the color temperature difference according to the color temperature of the ceiling light and the current color temperature, and comparing the color temperature difference with a preset color temperature threshold.

[0156] Step 203C, in response to determining that the color temperature difference is greater than a preset color temperature threshold, controlling the ceiling screen to adjust from the current color temperature to the target color temperature according to the color temperature of the ceiling light.

[0157] In the specific implementation, the color temperature of the ceiling light is determined based on the lighting parameters of the ceiling light. When the color temperature difference between the color temperature of the ceiling light and the current color temperature of the ceiling screen is greater than the preset color temperature threshold, it means that the ceiling light has color temperature interference on the ceiling screen, and the color temperature of the ceiling screen needs to be compensated.

[0158] The target color temperature of the ceiling screen after compensation is determined based on the color temperature of the roof light, and the ceiling screen is controlled to adjust from the current color temperature to the target color temperature, so that the ceiling screen can reach the color temperature before interference in terms of visual perception.

[0159] In some scenarios, the ceiling screen synchronizes image quality with other screens in the vehicle. When the ceiling light interferes with the color temperature of the ceiling screen, the user will feel that the color temperature of the ceiling screen is inconsistent with that of other screens. The ceiling screen is controlled to adjust from the current color temperature to the target color temperature according to the color temperature of the ceiling light, so that the user will feel that the color temperature of the ceiling screen is consistent with that of other screens.

[0160] When the roof light is a starry sky ceiling, the color temperature of the ceiling screen is adjusted based on the starry sky ceiling. The specific process includes: determining the color temperature of the starry sky ceiling based on the lighting parameters of the starry sky ceiling, and determining the color temperature difference between the color temperature of the starry sky ceiling and the current color temperature of the ceiling screen. When the color temperature difference is greater than the preset color temperature threshold, the ceiling screen is controlled to adjust from the current color temperature to the target color temperature according to the color temperature of the starry sky ceiling.

[0161] Through the above scheme, when the color temperature difference between the color temperature of the ceiling light and the current color temperature of the ceiling screen is greater than the preset color temperature threshold, the ceiling screen is controlled to adjust from the current color temperature to the target color temperature according to the color temperature of the ceiling light. In this way, when the ceiling light has color temperature interference on the ceiling screen, the color temperature of the ceiling screen is compensated according to the color temperature of the ceiling light, so that the ceiling screen can reach the color temperature before the interference in terms of visual perception, thereby ensuring the user's experience when watching the ceiling screen.

[0162] It should be noted that the embodiments of the present disclosure may be further described in the following manner:

[0163] Figure 2 FIG. 1 is a schematic diagram of the linkage control of two rear ceiling screens according to an embodiment of the present disclosure. Figure 2 As shown, the horizontal spacing between the two screens represents the horizontal distance (X) between the rear ceiling screen (left) and the rear ceiling screen (right), that is, the distance between the two ceiling screens.

[0164] ① The larger the X, the farther the distance between the rear ceiling screen (left) and the rear ceiling screen (right), the wider the vehicle horizontally, and the lower the visual consistency correlation between the two ceiling screens. That is, when the distance between the two ceiling screens is very far, it may not be necessary to overly ensure the picture quality consistency of the two ceiling screens. In other words, when X is large enough, the horizontal distance between the left and right rear passengers is far enough, and the two ceiling screens are far enough apart. When the picture quality of the two ceiling screens is inconsistent, the impact on visual consistency is small. At this time, because X is large enough, generally, the left rear passenger in the back row basically only looks at the left rear ceiling screen, and the right rear passenger in the back row basically only looks at the right rear ceiling screen. When there is no passenger in the middle position of the rear seat, the picture quality of the two ceiling screens can be different.

[0165] ② The smaller the X, the closer the distance between the rear ceiling screen (left) and the rear ceiling screen (right), the closer the vehicle horizontally, and the higher the visual consistency correlation between the two ceiling screens. At this time, the distance between the two ceiling screens is very close, and the horizontal distance between the left and right rear passengers is also very close, indicating that the vehicle is relatively narrow in the width direction. Then, the probability that the left and right passengers' fields of vision simultaneously observe the two ceiling screens is very high. Therefore, it is not recommended to keep the two ceiling screens different or to keep a large difference between the two ceiling screens, so as to avoid the discomfort caused by visual inconsistency when the probability of a certain passenger in the back row seeing the two ceiling screens simultaneously increases in a narrow space.

[0166] The preset distance thresholds include the first distance threshold X1 and the second distance threshold X2, where X1 < X2, X2 is the upper limit of the horizontal distance between the two ceiling screens, and X1 is the lower limit of the horizontal distance between the two ceiling screens.

[0167] (1)X > X2

[0168] X2 is the upper limit of the horizontal distance between the two ceiling screens. At this time, X > X2, indicating that the horizontal distance between the two ceiling screens is very large. Therefore, the rear passengers' dependence on the picture quality consistency of the two ceiling screens is relatively low. That is, at this time, the picture quality of the two ceiling screens can be different, and the difference has little impact on the vision of the rear passengers.

[0169] For example, the width of a business luxury car is relatively large, aiming to reflect the comfort of the luxury car. Therefore, it is more necessary to fully guarantee the different picture quality requirements of all rear passengers while taking into account visual consistency.

[0170] ① Changing the picture quality of any rear ceiling screen

[0171] a. When a rear passenger changes the picture quality of the first ceiling screen alone through voice or other means, the first ceiling screen responds to the parameters of the picture quality change, and the picture quality of the second ceiling screen remains unchanged.

[0172] b. Considering that passengers in the middle position of the rear seats will see two ceiling-mounted screens with different picture qualities successively when turning their heads, but the interior of the vehicle is relatively wide horizontally and the field of vision is relatively broad at this time. Therefore, when the picture quality of the first ceiling-mounted screen is changed, passengers in the middle position of the rear seats can simply choose the ceiling-mounted screen they are used to watching without the need for excessive prompts.

[0173] ② Simultaneous change of the picture qualities of the two ceiling-mounted screens in the rear row

[0174] a. When rear passengers change the picture qualities of the two ceiling-mounted screens simultaneously by voice or other means, regardless of whether the changed contents of the picture qualities of the two ceiling-mounted screens are the same or different, the two ceiling-mounted screens can directly respond to the same or different picture quality parameters because the two ceiling-mounted screens are far apart at this time and rear passengers have a low dependence on the picture quality consistency.

[0175] b. Regarding passengers in the middle position of the rear seats, it is the same as a in ①.

[0176] (2)X < X1

[0177] X1 is the lower limit of the horizontal distance between the two ceiling-mounted screens. At this time, X < X1, indicating that the horizontal distance between the two ceiling-mounted screens is very small. Therefore, rear passengers have a high dependence on the picture quality consistency of the two ceiling-mounted screens, that is, it is not recommended that there be a difference in the picture qualities of the two ceiling-mounted screens at this time. If there is a difference, it will have a greater impact on the vision of rear passengers. At this time, the distance between the two ceiling-mounted screens and the rear left and right passengers are all very compact, and the probability of seeing the two ceiling-mounted screens simultaneously is very high. In order to maximize the visual consistency and coherence effect of rear passengers and avoid causing visual discomfort, the following judgments are required.

[0178] For example, the vehicle width of a compact vehicle is small, but two rear ceiling-mounted screens still need to be designed to meet the entertainment needs. At this time, the interior of the vehicle is narrow, so it is necessary to give priority to ensuring visual consistency.

[0179] ① Change of the picture quality of any one of the rear ceiling-mounted screens

[0180] a. When a rear passenger changes the picture quality of the first ceiling-mounted screen alone by voice or other means, the picture quality of the second ceiling-mounted screen automatically coordinates.

[0181] b. After the picture qualities of the two ceiling-mounted screens are coordinated, it is a good experience for the visual experience of any rear passenger in the narrow and compact space. Therefore, the relevant description of passengers in the middle position of the rear seats is not elaborated separately.

[0182] c. Of course, after the picture quality of the two ceiling screens is automatically coordinated, if a passenger in the back row changes the picture quality of the second ceiling screen that is coordinated with it again (for example: the picture quality of the left rear ceiling screen is actively changed in a, and then the picture quality of the right rear ceiling screen is automatically coordinated, but within a period of time afterwards, if other passengers in the back row still actively change the picture quality of the right rear ceiling screen through voice or other means to restore the previous picture quality parameters or other parameters of the right rear ceiling screen, it means that the passenger subjectively hopes that the two ceiling screens will maintain a difference), it means that the passenger subjectively hopes that the picture quality of the two rear ceiling screens will maintain a difference. At this time, the system can first give a prompt on the right rear ceiling screen to explain the disadvantages of the picture quality difference. If the passenger still chooses the difference, the system can respond to the difference parameters.

[0183] ②The image quality of the two rear ceiling screens is changed at the same time

[0184] For example, the rear passengers can change the image quality of the two rear ceiling screens at the same time through voice or other means. However, when changing, the two ceiling screens have the same parameters or different parameters, so they need to be judged separately.

[0185] a. The image quality changes are the same

[0186] For example, the rear passenger says by voice: Please increase the brightness of the two rear ceiling screens, which means that the passenger subjectively hopes that the image quality of the two ceiling screens will be coordinated. At this time, the image quality of the two ceiling screens will be synchronously coordinated to respond to the same parameters.

[0187] b. The image quality changes are different, but the difference is small

[0188] For example, the rear passenger says through voice: Please increase the brightness of the left rear ceiling screen to 35%, and lower the brightness of the right rear ceiling screen to 30%. The voice can make differentiated demands at the same time, or one after another. It means that the passenger subjectively hopes that the image quality of the two ceiling screens will be differentiated, but the difference between 30% and 35% is small, and the perception of differentiation is low. Therefore, at this time, the image quality of the two ceiling screens responds with different parameters synchronously or one after another.

[0189] c. The content of the image quality changes is different, but the difference is large

[0190] For example, the rear passengers say at the same time or successively through voice: Please increase the brightness of the left rear ceiling screen to 90%, and lower the brightness of the right rear ceiling screen to 30%. This means that the passengers subjectively hope that the image quality of the two ceiling screens can be differentiated, but the difference between 90% and 30% is large, and the perception of differentiation is large, which affects the visual consistency of all rear passengers, especially the passengers in the middle position of the rear seats. In a narrow space, it is easy to cause visual discomfort when the eyeballs move slightly between the two compact ceiling screens. At this time, the image quality parameters of the two ceiling screens cannot respond directly. Passengers need to be informed through active prompts or voice interactions on the two ceiling screens that such changes will have disadvantages, which will play a sufficient prompting role and be executed according to the passengers' choices.

[0191] (3) X1≤X≤X2

[0192] At this time, the distance between the two ceiling screens is normal, not too large or too small.

[0193] Under normal circumstances, the picture quality only needs to be coordinated. After coordination, the screen will display coordination prompts and support passengers to customize changes.

[0194] Through the above embodiment, when the vehicle is installed with dual ceiling screens in the rear row, the two ceiling screens cannot directly coordinate the image quality. According to the comparison results between the horizontal distance between the two ceiling screens and the preset first distance threshold, the second distance threshold and other factors, the dependence of the rear passengers on the coordinated image quality of the two ceiling screens is judged, and finally the coordinated relationship (cooperation or differentiation) of the image quality of the two ceiling screens is determined in different scenarios.

[0195] It should be noted that the method of the embodiment of the present disclosure can be performed by a single device, such as a computer or a server. The method of the present embodiment can also be applied in a distributed scenario and completed by multiple devices cooperating with each other. In the case of such a distributed scenario, one of the multiple devices can only perform one or more steps in the method of the embodiment of the present disclosure, and the multiple devices will interact with each other to complete the described method.
