Abstract

The present application provides a method, device, vehicle and storage medium for screen control. When the vehicle is in motion and the target user needs to watch the target picture through the in-vehicle screen, if the target user experiences motion sickness, the method reduces the current occupied area of ​​the picture-lit area on the in-vehicle screen.

Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and more specifically, to a method, device, vehicle, and storage medium for screen control in the field of vehicle technology. Background Art

[0002] With the continuous advancement of vehicle technology and the improvement of people's living standards, the user base of vehicles is becoming wider and wider. However, with this, there are also more and more vehicle-related problems, including motion sickness problems of users during driving.

[0003] In some scenarios, users need to use the in-vehicle screen for work or entertainment while the vehicle is in motion. However, looking at the in-vehicle screen for a long time and at a close distance can easily cause motion sickness.

[0004] Therefore, there is an urgent need for a screen control method to meet the user's viewing needs for the vehicle-mounted screen in the car and alleviate the user's motion sickness. Summary of the Invention

[0005] The present application provides a screen control method, device, vehicle and storage medium, which can meet the target user's viewing needs for the vehicle-mounted screen in the car and alleviate the target user's motion sickness symptoms.

[0006] In a first aspect, a screen control method is provided, the method comprising: when a vehicle is in a driving state and a target user in the vehicle is viewing a target picture through a first vehicle-mounted screen, determining whether the target user is in a motion sickness state; when the target user is in a motion sickness state, determining a target control parameter, the target control parameter being used to indicate that a picture lighting area on the first vehicle-mounted screen should be in a first occupied area and a first position on the first vehicle-mounted screen, a backlight source corresponding to the picture lighting area is turned on and the picture lighting area is used to display the target picture; based on the target control parameter, reducing the current occupied area of ​​the current picture lighting area on the first vehicle-mounted screen, and adjusting the current position of the current picture lighting area on the first vehicle-mounted screen.

[0007] In the above technical solution, when the vehicle is in motion and the target user in the vehicle must view the target image through the first vehicle-mounted screen, if the target user experiences motion sickness, the vehicle in the method can reduce the current occupied area of ​​the image lighting area on the first vehicle-mounted screen used to display the target image, and adjust the current position of the image lighting area on the first vehicle-mounted screen. That is, the backlight corresponding to the image lighting area is turned on, and the area of ​​the image lighting area viewed by the target user becomes smaller, which takes up less visual space and increases the contrast between the image lighting area and other display areas, so that the target user does not need to frequently adjust the eye focus, thereby reducing eye fatigue. In addition, the current position of the image lighting area viewed by the target user is adjusted to a first position adapted to the target user, which can prevent the target user from excessively tilting his head or neck, helps to keep his head stable, and reduces stimulation to the target user's vestibular system. Therefore, the method can alleviate the target user's motion sickness symptoms and meet the target user's viewing needs for the first vehicle-mounted screen in the car.

[0008] In combination with the first aspect, in some possible implementations, determining the target control parameters includes any one of the following: in response to the target user clicking the parameter configuration control on the first vehicle-mounted screen, displaying a parameter configuration list on the first vehicle-mounted screen, the parameter configuration list being used to configure the occupied area and position of the screen lighting area on the first vehicle-mounted screen; determining the first occupied area and the first position based on the parameter configuration list; determining the first occupied area based on the target user's motion sickness level, the target user's motion sickness level being negatively correlated with the first occupied area; and determining the first position based on the target user's eye position, the target user's eye position corresponding to the first position.

[0009] In the above technical solution, the target user can configure the first occupied area and first position in the parameter configuration list displayed on the first in-vehicle screen by clicking the parameter configuration control on the first in-vehicle screen. This allows the target user to customize the screen illumination area based on their motion sickness needs, thereby not only determining control parameters that can alleviate the target user's motion sickness symptoms but also fully considering the target user's preferences, which can enhance the target user's in-vehicle experience. Furthermore, the method can directly determine the first occupied area based on the target user's motion sickness level and the first position based on the target user's eye position. This adaptive control of the screen illumination area based on the target user's actual motion sickness level avoids situations where the target user fails to respond to the parameter configuration control and the target control parameters cannot be determined. Furthermore, target users with different motion sickness levels can obtain a first occupied area that is tailored to their individual motion sickness condition. This allows for precise adjustment based on their individual motion sickness condition. For example, when the motion sickness level is high, the screen illumination area occupies only a small portion, which can reduce visual scene switching and the visual impact of dynamic images. Furthermore, determining the first position based on the target user's eye position ensures that the target user views the target image from the most natural and comfortable perspective.

[0010] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the method also includes: determining the area difference between the display area on the first vehicle-mounted screen and the first occupied area; adjusting the display area corresponding to the area difference on the first vehicle-mounted screen to a blackout area, the backlight source corresponding to the blackout area is turned off and the blackout area is not used to display the target screen.

[0011] In the above technical solution, when the target user is in a state of motion sickness, the method reduces the occupied area of ​​the current screen lighting area used to display the target screen to the first occupied area, and adjusts the position of the current screen lighting area to the first occupied area. In addition, the other display areas on the first vehicle-mounted screen except the current screen lighting area are adjusted to the extinguished area. For the target user, the display area showing the target screen becomes smaller, which can greatly reduce the visual impact on the target user, reduce the focusing effort of the target user's eyes, and thus reduce the fatigue of the eyes. Moreover, the current screen lighting area is surrounded by a black background, which can absorb the brightness of the current screen lighting area, reduce the stimulation of light reflection on the target user's eyes, and thus relieve eye fatigue. In addition, the black background can increase the contrast between the current screen lighting area and the extinguished area, making the target screen clearer and more vivid, making it easier for the target user to identify and understand the target screen, and reducing the visual burden on the eyes.

[0012] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the method also includes: determining N brightnesses between the first brightness of the current picture lighting area and the second brightness of the unlit area according to a preset brightness step value, where N is a positive integer greater than or equal to 1; in the unlit area, determining a candidate display area, which is close to the boundary between the current picture lighting area and the unlit area; dividing the candidate display area into N target display areas in left-right order; turning on the backlight sources corresponding to the N target display areas, and adjusting the brightness of each target display area in the N target display areas to a corresponding brightness among the N brightnesses.

[0013] In the above technical solution, the method determines a candidate display area in the extinguished area, divides the candidate display area into N target display areas in a left-right order, turns on the backlight sources corresponding to the N target display areas, and adjusts the brightness of each target display area to a brightness corresponding to a first brightness and a second brightness. In other words, the method sets a multi-brightness gradient transition zone between the current display area and the extinguished area according to the actual first brightness of the current display area and the second brightness of the extinguished area. This can avoid the visual impact of the current display area on the target user when the contrast between the lit area and the extinguished area of ​​the current picture is very obvious. The gradient transition zone can act as a buffer, allowing the target user's eyes to gradually adapt to the change in brightness and not feel uncomfortable due to sudden changes in brightness.

[0014] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, based on the target control parameters, the current occupied area of ​​the current screen lighting area on the first vehicle-mounted screen is reduced, and the current position of the current screen lighting area on the first vehicle-mounted screen is adjusted, including: when the target user is the passenger seat user in the vehicle, determining whether the first vehicle-mounted screen is the passenger seat ceiling screen in the vehicle; when the first vehicle-mounted screen is the passenger seat ceiling screen, based on the target control parameters, reducing the current occupied area and adjusting the current position.

[0015] In the above technical solution, when the target user is the front passenger and the first in-vehicle screen is a front passenger ceiling screen, the front passenger's viewing behavior will not affect the driver's safe driving of the vehicle. Therefore, the method can directly adjust the current screen lighting area, reducing the current occupied area of ​​the current screen lighting area to the first occupied area, and adjusting the current position of the current screen lighting area to the first position. In this way, the method not only considers the impact of changes in the display parameters of the current screen lighting area on other users (drivers), avoiding traffic accidents, but also minimizes the front passenger's motion sickness symptoms.

[0016] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the method also includes: when the first vehicle-mounted screen is the passenger entertainment screen in the vehicle, determining whether the target screen is a preset display screen, and the preset display screen is used to display the driving content required by the driver; when the target screen is not the preset display screen, based on the target control parameters, the current occupied area is reduced, and the current position is adjusted; when the target screen is the preset display screen, the target screen is copied and switched to the passenger ceiling screen, and at the same time, the occupied area of ​​the first lighting area on the passenger ceiling screen is adjusted to the second occupied area, and the position of the first lighting area on the passenger ceiling screen is adjusted to the second position, the first lighting area is the display area on the passenger ceiling screen for displaying the target screen and the backlight source corresponding to the first lighting area is turned on, the second occupied area is related to the first occupied area, and the second position is related to the first position.

[0017] In the above technical solution, when the target user is the co-pilot user and the first vehicle-mounted screen is the co-pilot entertainment screen, and the target screen is not the preset display screen, the viewing behavior of the co-pilot user will not affect the driver's safe driving of the vehicle. Therefore, the method can directly adjust the current screen lighting area. When the target screen is the preset display screen, if the current screen lighting area is adjusted directly, it will cause the driver to lose his way because he cannot obtain driving content (such as navigation information), increase driving time, etc. When the target user is the co-pilot user and the first vehicle-mounted screen is the co-pilot entertainment screen, and the target screen is the preset display screen, the method copies the target screen and switches it to the co-pilot ceiling screen, and adjusts the first lighting area at the same time. This not only does not prevent the driver from continuing to obtain driving content through the co-pilot entertainment screen, but also ensures that the co-pilot user continues to watch the target screen and alleviates the co-pilot user's motion sickness symptoms.

[0018] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, based on the target control parameter, the current occupied area of ​​the current screen lighting area on the first vehicle-mounted screen is reduced, and the current position of the current screen lighting area on the first vehicle-mounted screen is adjusted, including: when the target user is a rear-seat user in the vehicle, determining a first number of target users in a motion sickness state and a second number of reference users who are not in a motion sickness state, the reference users being rear-seat users and watching the second vehicle-mounted screen; when the first number is a first preset number and the second number is a second preset number, based on the target control parameter, reducing the current occupied area and adjusting the current position; when the first number is the first preset number and the second number is greater than the second preset number, determining whether the second vehicle-mounted screen is the first vehicle-mounted screen; when the second vehicle-mounted screen is not the first vehicle-mounted screen, reducing the current occupied area and adjusting the current position based on the target control parameter.

[0019] In the above technical solution, when the target user is a rear-seat user, the method determines a first number of target users and a second number of reference users who are not experiencing motion sickness. This allows the determination of the number of rear-seat users viewing the in-vehicle screen and experiencing motion sickness, as well as the number of rear-seat users viewing the in-vehicle screen and not experiencing motion sickness. When the first number is the first preset number and the second number is the second preset number, only the target user is in the rear seat of the vehicle, and the current screen illumination area can be adjusted directly. However, when the first number is the first preset number and the second number is greater than the second preset number, there are also reference users viewing the in-vehicle screen. If the reference users and the target users are viewing the same in-vehicle screen, directly adjusting the current screen illumination area could cause a sudden change in the reference users' viewing field of view, impacting the reference users' viewing experience. When the first number is the first preset number and the second number is greater than the second preset number, the method further determines whether the reference users' viewing fields overlap with the target users'. Only when there is no overlap is the current screen illumination area adjusted. This prevents adjustments to the current screen illumination area from impacting the reference users' in-vehicle experience.

[0020] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the method also includes: when the second vehicle-mounted screen is the first vehicle-mounted screen, or when the first number is greater than the first preset number, determining a third vehicle-mounted screen adapted for the target user from multiple vehicle-mounted screens, and the third vehicle-mounted screen does not conflict with the vehicle-mounted screens viewed by other users; switching the target screen to the third vehicle-mounted screen, and adjusting the occupied area of ​​the second lighting area on the third vehicle-mounted screen to the third occupied area, and adjusting the position of the second lighting area on the third vehicle-mounted screen to the third position, the second lighting area is the display area on the third vehicle-mounted screen for displaying the target screen and the backlight source corresponding to the second lighting area is turned on, the third occupied area is related to the first occupied area, and the third position is related to the first position.

[0021] In the above technical solution, when a target user experiences motion sickness and is viewing the same in-vehicle screen as a reference user, or when multiple target users experience motion sickness, the method determines a third in-vehicle screen suitable for the target user from among the multiple in-vehicle screens, simultaneously switches the target image to the third in-vehicle screen, and adjusts the second illuminated area. This maximizes the matching of the unified in-vehicle screen, not only meeting the target user's viewing needs with minimal screen resources, but also alleviating the target user's motion sickness symptoms.

[0022] In a second aspect, a screen control device is provided, which includes: a determination module for: when a vehicle is in a driving state and a target user in the vehicle is watching a target picture through a first vehicle-mounted screen, determining whether the target user is in a motion sickness state; when the target user is in a motion sickness state, determining a target control parameter, the target control parameter being used to indicate that the picture lighting area on the first vehicle-mounted screen should be in a first occupied area and a first position on the first vehicle-mounted screen, the backlight source corresponding to the picture lighting area is turned on and the picture lighting area is used to display the target picture; an adjustment module for, based on the target control parameter, reducing the current occupied area of ​​the current picture lighting area on the first vehicle-mounted screen and adjusting the current position of the current picture lighting area on the first vehicle-mounted screen.

[0023] In combination with the second aspect, in some possible implementations, the device also includes: a display module for displaying a parameter configuration list on the first vehicle-mounted screen in response to the target user's click operation on the parameter configuration control on the first vehicle-mounted screen, wherein the parameter configuration list is used to configure the occupied area and position of the screen lighting area on the first vehicle-mounted screen; the determination module is specifically used for any one of the following: determining the first occupied area and the first position based on the parameter configuration list; determining the first occupied area based on the target user's motion sickness level, the target user's motion sickness level is negatively correlated with the first occupied area; and determining the first position based on the target user's eye position, the target user's eye position corresponding to the first position.

[0024] In combination with the second aspect and the above-mentioned implementation methods, in some possible implementation methods, the determination module is also used to determine the area difference between the display area on the first vehicle-mounted screen and the first occupied area; the adjustment module is also used to adjust the display area corresponding to the area difference on the first vehicle-mounted screen to a blackout area, and the backlight source corresponding to the blackout area is turned off and the blackout area is not used to display the target screen.

[0025] In combination with the second aspect and the above-mentioned implementation methods, in some possible implementation methods, the determination module is also used to: determine N brightnesses between the first brightness of the current picture lighting area and the second brightness of the unlit area according to a preset brightness step value, where N is a positive integer greater than or equal to 1; in the unlit area, determine a candidate display area, which is close to the boundary between the current picture lighting area and the unlit area; divide the candidate display area into N target display areas in a left-right order; the adjustment module is also used to turn on the backlight sources corresponding to the N target display areas, and adjust the brightness of each target display area in the N target display areas to a corresponding brightness among the N brightnesses.

[0038] The following is a clear and detailed description of the technical solutions in this application in conjunction with the accompanying drawings. In the description of the embodiments of this application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and" in the text is only a description of the association relationship between related objects, indicating that there can be three relationships, for example, A and B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of this application, "multiple" means two or more than two.

[0039] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood to imply or suggest relative importance or implicitly indicate the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0040] Figure 1 This is a schematic diagram of a vehicle usage scenario provided in an embodiment of the present application.

[0041] In some practical scenarios, users need to work on the vehicle screen while the vehicle is in motion. For example, Figure 1 As shown, in most cases, the business owner will have to handle business through the in-vehicle screen in vehicle A due to various emergencies. This may be due to fierce market competition, requiring the business owner to make an immediate decision; or a sudden change in customer demand, requiring the business owner to quickly adjust the plan.

[0042] However, if the user stares at the in-vehicle screen for a long time and at a close distance, the user may easily suffer from motion sickness, which may affect the user's riding experience to a certain extent.

[0043] In order to solve the above problems, this application provides a screen control method to meet the user's viewing needs for the car screen in the car and relieve the user's motion sickness symptoms. The specific implementation steps are as follows: Figure 2 shown.

[0044] Figure 2 This is a schematic flowchart of a screen control method provided in an embodiment of the present application.

[0045] It should be understood that the screen control method provided in the embodiment of the present application can be applied to Figure 1 The vehicle shown (eg, vehicle A). Specifically, the screen control method can be applied to the vehicle controller in the vehicle.

[0046] For example, Figure 2 As shown, the method 200 includes the following steps 201 to 203.

[0047] Step 201: When a vehicle is in a driving state and a target user in the vehicle is viewing a target image through a first vehicle-mounted screen, the vehicle controller determines whether the target user is in a motion sickness state.

[0048] It should be understood that the "first in-vehicle screen" in step 201 is any in-vehicle screen in the vehicle that can provide entertainment functions and work needs for the target user. In some embodiments, the first in-vehicle screen is any one of a passenger entertainment screen, a rear seatback screen, a passenger ceiling screen, and a rear ceiling screen.

[0049] It should also be understood that the “target image” in the above step 201 refers to the continuous frame images displayed on the first vehicle-mounted screen.

[0050] It should also be understood that, regardless of whether the "target user" in step 201 is the front-seat user or the back-seat user in the vehicle, if the target user watches the target image played on the first in-vehicle screen for a long time, the target user will suffer from motion sickness. Specifically, for the front-seat user, watching the target image for a long time will cause the neck muscles to continuously contract, resulting in compression of the blood vessels in the neck, which in turn reduces the blood supply to the brain tissue, and may cause symptoms of motion sickness. However, the front-seat user has a wider field of view and is less likely to suffer from motion sickness than the back-seat user. For the back-seat user, the back-seat user cannot see the road ahead, which means that the back-seat user lacks first visual information about how the vehicle is moving. In this case, there is a difference between the motion state perceived by the body and the position information perceived by the vision. This difference will stimulate the vestibular organs of the back-seat user, which will increase the probability of the back-seat user suffering from motion sickness.

[0051] It should also be understood that when the target user is in a motion sickness state in step 201, the target user may experience the following symptoms, including drowsiness (closing eyes and opening mouth, frequent nodding, bloodshot eyes, and tears in the eyes), nausea, vomiting, dizziness, headache, cold sweats, pale complexion, tinnitus, and stuffy ears, etc. When the vehicle is traveling on a bumpy road, or the vehicle's driving mode is the target driving mode (the target driving mode is used to affect the vehicle's driving stability), or the vehicle brakes frequently, the target user who views the target image for a long time is likely to experience motion sickness.

[0052] Step 202, when the target user is in a state of motion sickness, the vehicle controller determines the target control parameters, which are used to indicate that the picture lighting area on the first vehicle-mounted screen should be in the first occupied area and first position on the first vehicle-mounted screen, and the backlight source corresponding to the picture lighting area is turned on and the picture lighting area is used to display the target picture.

[0053] It should be understood that the "target control parameter" in step 202 is used to control the occupied area and position of the screen lighting area displaying the target screen on the first vehicle screen. The first occupied area can be represented by the ratio between the screen lighting area and the area of ​​the first vehicle screen.

[0054] It should also be understood that the backlight source corresponding to the "screen lighting area" in the above step 202 (the light source behind the screen lighting area in the first vehicle screen) is turned on. The turned-on backlight source can ensure that the screen lighting area displays the target screen with a certain brightness, and can improve the contrast between the screen lighting area and other display areas.

[0055] In some embodiments, the first occupied area is represented by a percentage.

[0056] In some embodiments, the first occupied area is 60%.

[0057] In some embodiments, the first position includes any one of a middle position, a left position, a right position, an upper left corner position, an upper right corner position, a lower left corner position, and a lower right corner position.

[0058] The process of determining whether the target user is in a motion sickness state is described below.

[0059] In some embodiments, the method for determining that the target user is in a motion sickness state includes at least one of the following: when the target user triggers the anti-motion sickness mode in the vehicle, the vehicle controller determines that the target user is in a motion sickness state; when the vehicle is traveling at a level of stability higher than or equal to a preset level of stability and the target user lowers his head more than a first preset number of times, the vehicle controller determines that the target user is in a motion sickness state; when the level of stability is lower than the preset level of stability and the target user's eyes are closed for a period of time longer than a first preset period of time, the vehicle controller determines that the target user is in a motion sickness state; when the vehicle brakes more than a second preset number of times and the target user's mouth is open for a period of time longer than a second preset period of time, the vehicle controller determines that the target user is in a motion sickness state; when the target user's mouth is open and the target user's eyes are closed, the vehicle controller determines that the target user is in a motion sickness state.

[0060] It should be understood that the "anti-motion sickness mode" in the above solution refers to a mode used to alleviate the target user's motion sickness symptoms. In some embodiments, the target user triggers the anti-motion sickness mode by voice; or by clicking an anti-motion sickness button in the vehicle, which can be a physical button or a virtual button on the vehicle's screen; or by making an anti-motion sickness gesture, such as an open palm gesture.

[0061] In some embodiments, the smoothness of the vehicle during driving is lower than a preset smoothness, which includes the bumpiness of the road surface on which the vehicle is driving being within a preset range and the driving mode of the vehicle being a target driving mode, which is used to affect the smoothness of the vehicle.

[0062] In some embodiments, the target driving mode is any one of a sand mode, a snow mode, an off-road mode, and a sport mode.

[0063] In some embodiments, the method for determining the smoothness of the vehicle during driving includes: the vehicle controller obtains multiple accelerations of the vehicle within a target time length; the vehicle controller determines the variance of the multiple accelerations as the smoothness; or, the vehicle controller determines the mean square error of the multiple accelerations as the smoothness.

[0064] In some embodiments, when the variance of the multiple accelerations is greater than or equal to a preset variance, the vehicle controller determines that the vehicle's driving smoothness is higher than or equal to the preset smoothness; when the variance of the multiple accelerations is less than the preset variance, the vehicle controller determines that the vehicle's driving smoothness is lower than the preset smoothness; or, when the mean square error of the multiple accelerations is greater than or equal to the preset mean square error, the vehicle controller determines that the vehicle's driving smoothness is higher than or equal to the preset smoothness; when the mean square error of the multiple accelerations is less than the preset mean square error, the vehicle controller determines that the vehicle's driving smoothness is lower than the preset smoothness.

[0065] In some embodiments, when the target user's mouth is open and the target user's eyes are closed, the vehicle controller determines that the target user is in a motion sickness state, including: when the target user's mouth is open, the target user's eyes are open and the degree of opening is less than a first preset degree, and the eyes are in a congested state and contain tears, the vehicle controller determines that the target user is in a motion sickness state.

[0066] The process of determining the “target control parameter” is described below.

[0067] In one possible implementation, the vehicle controller in step 202 determines the target control parameters, including any one of the following: the vehicle controller displays a parameter configuration list on the first vehicle screen in response to the target user clicking the parameter configuration control on the first vehicle screen, and the parameter configuration list is used to configure the occupied area and position of the screen lighting area on the first vehicle screen; the vehicle controller determines the first occupied area and the first position based on the parameter configuration list; the vehicle controller determines the first occupied area based on the motion sickness level of the target user, and the motion sickness level of the target user is negatively correlated with the first occupied area; and the vehicle controller determines the first position based on the eye position of the target user, and the eye position of the target user corresponds to the first position.

[0068] It should be understood that in the above solution, after determining that the target user is in a state of motion sickness, the vehicle controller displays a parameter configuration control on the first vehicle screen. The parameter configuration control is used to control the display of a parameter configuration list, which includes multiple parameter configuration items and corresponding configuration boxes. Among them, the multiple parameter configuration items include a configuration item for configuring the area corresponding to the occupied area of ​​the screen lighting area on the first vehicle screen, a configuration item for configuring the position corresponding to the screen lighting area, etc. The configuration box is used to configure (fill in) the specific value of the corresponding parameter configuration item.

[0069] It should also be understood that the "negative correlation between the target user's motion sickness level and the first occupied area" in the above solution means that the lower the target user's motion sickness level, the larger the first occupied area; and the higher the motion sickness level, the smaller the first occupied area. However, if the first occupied area is greater than or equal to the preset occupied area, which is the minimum screen display area that meets the field of view, this preset occupied area does not affect the target user's ability to read information in the illuminated area of ​​the screen.

[0070] It should also be understood that "the target user's eye position corresponds to the first position" in the above solution means that the first position is consistent with the position of the target user's eyes relative to the first vehicle-mounted screen.

[0071] In the above technical solution, the target user can configure the first occupied area and first position in the parameter configuration list displayed on the first in-vehicle screen by clicking the parameter configuration control on the first in-vehicle screen. This allows the target user to customize the screen illumination area based on their motion sickness needs, thereby not only determining control parameters that can alleviate the target user's motion sickness symptoms but also fully considering the target user's preferences, which can enhance the target user's in-vehicle experience. Furthermore, the method can directly determine the first occupied area based on the target user's motion sickness level and the first position based on the target user's eye position. This adaptive control of the screen illumination area based on the target user's actual motion sickness level avoids situations where the target user fails to respond to the parameter configuration control and the target control parameters cannot be determined. Furthermore, target users with different motion sickness levels can obtain a first occupied area that is tailored to their individual motion sickness condition. This allows for precise adjustment based on their individual motion sickness condition. For example, when the motion sickness level is high, the screen illumination area occupies only a small portion, which can reduce visual scene switching and the visual impact of dynamic images. Furthermore, determining the first position based on the target user's eye position ensures that the target user views the target image from the most natural and comfortable perspective.

[0072] In some embodiments, the parameter configuration list is also used to configure the screen lighting area to occupy an area and a position and display duration on the first vehicle screen.

[0073] In some embodiments, the vehicle controller determines the first occupied area based on the motion sickness level of the target user, including: when the motion sickness level is the first level, the vehicle controller determines the first occupied area as a first area percentage; when the motion sickness level is the second level, the vehicle controller determines the first occupied area as a second area percentage; when the motion sickness level is the third level, the vehicle controller determines the first occupied area as a third area percentage, the first level is higher than the second level, the second level is higher than the third level, the first area percentage is smaller than the second area percentage, and the second area percentage is smaller than the third area percentage.

[0074] In some embodiments, the vehicle controller determines the first position based on the eye position of the target user, including: when the eye position indicates that the target user's eyes are in the middle of the first vehicle-mounted screen, the vehicle controller determines the first position as the middle position; when the eye position indicates that the target user's eyes are on the upper left side of the first vehicle-mounted screen, the vehicle controller determines the first position as the upper left corner position; when the eye position indicates that the target user's eyes are on the left side of the first vehicle-mounted screen, the vehicle controller determines the first position as the left position; when the eye position indicates that the target user's eyes are on the upper right side of the first vehicle-mounted screen, the vehicle controller determines the first position as the upper right corner position; when the eye position indicates that the target user's eyes are on the lower left side of the first vehicle-mounted screen, the vehicle controller determines the first position as the lower left corner position; when the eye position indicates that the target user's eyes are on the lower right side of the first vehicle-mounted screen, the vehicle controller determines the first position as the lower right corner position.

[0075] It should be understood that the target user's eyes can also be located in other positions relative to the first in-vehicle screen. In the above solution, only the above-mentioned positions (such as the eyes being located in the center of the first in-vehicle screen, etc.) are described as examples. The cases where the eyes are located in other positions relative to the first in-vehicle screen are similar to the above examples and will not be repeated here.

[0076] In step 203 , the vehicle controller reduces the current occupied area of ​​the current picture lighting area on the first vehicle screen and adjusts the current position of the current picture lighting area on the first vehicle screen based on the target control parameter.

[0077] It should be understood that the above step 203 describes: based on the target control parameters, the current occupied area of ​​the current picture lighting area on the first vehicle screen is reduced to the first occupied area, and the current position of the current picture lighting area (the current position of the current picture lighting area on the first vehicle screen) is adjusted to the first position.

[0078] In some embodiments, step 203 includes: the vehicle controller displays a first reminder message on the first vehicle screen, and the first reminder message is used to remind whether the current screen lighting area can be adjusted; when receiving a confirmation instruction from the target user for the first reminder message, the vehicle controller reduces the current occupied area of ​​the current screen lighting area on the first vehicle screen based on the target control parameters, and adjusts the current position of the current screen lighting area on the first vehicle screen.

[0079] In some embodiments, after the vehicle controller displays the first reminder information on the first vehicle screen, the method 200 also includes: when no confirmation instruction from the target user for the first reminder information is received, or when an instruction is received not to adjust the current screen lighting area, the vehicle controller maintains the current occupied area and current position of the current screen lighting area on the first vehicle screen.

[0080] The process of “adjusting the current screen lighting area when the target user is a different user” is described below.

[0081] The first type: The target user is the front passenger seat user.

[0082] In one possible implementation, step 203 includes: when the target user is the passenger seat user in the vehicle, the vehicle controller determines whether the first vehicle-mounted screen is the passenger seat ceiling screen in the vehicle; when the first vehicle-mounted screen is the passenger seat ceiling screen, the vehicle controller reduces the current occupied area and adjusts the current position based on the target control parameters.

[0083] It should be understood that in the above scenario, the passenger seat user may view the target image through the passenger seat ceiling screen or through the passenger seat entertainment screen. When the passenger seat user views the target image through the passenger seat ceiling screen, their viewing behavior has no essential relevance to the driver's ability to safely operate the vehicle. For example, the driver would not use the passenger seat ceiling screen to obtain navigation information.

[0084] In the above technical solution, when the target user is the front passenger and the first in-vehicle screen is a front passenger ceiling screen, the front passenger's viewing behavior will not affect the driver's safe driving of the vehicle. Therefore, the method can directly adjust the current screen lighting area, reducing the current occupied area of ​​the current screen lighting area to the first occupied area, and adjusting the current position of the current screen lighting area to the first position. In this way, the method not only considers the impact of changes in the display parameters of the current screen lighting area on other users (drivers), avoiding traffic accidents, but also minimizes the front passenger's motion sickness symptoms.

[0085] In one possible implementation, the method 200 also includes: when the first vehicle-mounted screen is the passenger entertainment screen in the vehicle, the vehicle controller determines whether the target screen is a preset display screen, which is used to display the driving content required by the driver; when the target screen is not the preset display screen, the vehicle controller reduces the current occupied area and adjusts the current position based on the target control parameters; when the target screen is the preset display screen, the vehicle controller copies the target screen and switches it to the passenger ceiling screen, and at the same time adjusts the occupied area of ​​the first lighting area on the passenger ceiling screen to the second occupied area, and adjusts the position of the first lighting area on the passenger ceiling screen to the second position, the first lighting area is the display area on the passenger ceiling screen for displaying the target screen and the backlight source corresponding to the first lighting area is turned on, the second occupied area is related to the first occupied area, and the second position is related to the first position.

[0086] It should be understood that in the above solution, when the passenger seat user views the target image on the passenger entertainment screen, the target image may be driving content required by the driver, such as navigation information or a 360-degree rearview camera. The driver needs to use this driving content to assist in safe driving. Therefore, the process of adjusting the current display area also requires prioritizing the analysis of the target image.

[0087] It should also be understood that in the above solution, when the target image currently displayed in the passenger seat entertainment screen is the preset display image, in order to alleviate the passenger seat user's motion sickness symptoms and not affect the driver's need to obtain driving content, the target image can be copied and switched to the passenger seat ceiling screen. In this case, the driver can still obtain driving content through the passenger seat entertainment screen, and the passenger seat user can still view the target image, and the passenger seat user's motion sickness symptoms can be alleviated.

[0088] It should also be understood that the “second occupied area is related to the first occupied area” in the above scheme refers to the second occupied area of ​​the first lighting area on the passenger ceiling screen, which is related to the first occupied area of ​​the picture lighting area on the first vehicle-mounted screen. In some embodiments, the second occupied area is the same as the first occupied area. The “second position is related to the first position” in the above scheme refers to the second position of the first lighting area on the passenger ceiling screen, which is consistent with the first position of the picture lighting area on the first vehicle-mounted screen. For example, the current picture lighting area is in the middle position on the first vehicle-mounted screen, and the first lighting area is in the middle position on the passenger ceiling screen. For another example, the current picture lighting area is on the right side of the first vehicle-mounted screen, and the first lighting area is on the right side of the passenger ceiling screen.

[0089] In the above technical solution, when the target user is the co-pilot user and the first vehicle-mounted screen is the co-pilot entertainment screen, and the target screen is not the preset display screen, the viewing behavior of the co-pilot user will not affect the driver's safe driving of the vehicle. Therefore, the method can directly adjust the current screen lighting area. When the target screen is the preset display screen, if the current screen lighting area is adjusted directly, it will cause the driver to lose his way because he cannot obtain driving content (such as navigation information), increase driving time, etc. When the target user is the co-pilot user and the first vehicle-mounted screen is the co-pilot entertainment screen, and the target screen is the preset display screen, the method copies the target screen and switches it to the co-pilot ceiling screen, and adjusts the first lighting area at the same time. This not only does not prevent the driver from continuing to obtain driving content through the co-pilot entertainment screen, but also ensures that the co-pilot user continues to watch the target screen and alleviates the co-pilot user's motion sickness symptoms.

[0090] In some embodiments, when the target screen is the preset display screen, the vehicle controller copies the target screen and switches it to the passenger ceiling screen, and at the same time adjusts the occupied area of ​​the first lighting area on the passenger ceiling screen to the second occupied area, and adjusts the position of the first lighting area on the passenger ceiling screen to the second position, including: when the target screen is the preset display screen, the vehicle controller displays a second reminder message on the first vehicle screen, and the second reminder message is used to remind whether to copy and switch the target screen to the passenger ceiling screen, and adjust the first lighting area used to display the target screen on the passenger ceiling screen; when receiving a confirmation instruction from the target user for the second reminder message, the vehicle controller copies and switches the target screen to the passenger ceiling screen, and at the same time adjusts the occupied area of ​​the first lighting area on the passenger ceiling screen to the second occupied area, and adjusts the position of the first lighting area on the passenger ceiling screen to the second position.

[0091] In some embodiments, after the vehicle controller displays the second reminder information on the first vehicle screen, the method 200 also includes: when the target user does not receive a confirmation instruction for the second reminder information, or when an instruction is received not to copy the target screen and switch to the co-pilot ceiling screen, the vehicle controller maintains the current occupied area and current position of the current screen lighting area on the co-pilot entertainment screen.

[0092] The second type: the target users are the back row users.

[0093] In one possible implementation, step 203 includes: when the target user is a rear-seat user in the vehicle, the vehicle controller determines a first number of target users who are in a motion sickness state and a second number of reference users who are not in a motion sickness state, and the reference users are rear-seat users and watch the second vehicle-mounted screen; when the first number is a first preset number and the second number is a second preset number, the vehicle controller reduces the current occupied area and adjusts the current position based on the target control parameter; when the first number is the first preset number and the second number is greater than the second preset number, the vehicle controller determines whether the second vehicle-mounted screen is the first vehicle-mounted screen; when the second vehicle-mounted screen is not the first vehicle-mounted screen, the vehicle controller reduces the current occupied area and adjusts the current position based on the target control parameter.

[0094] It should be understood that the "first preset number" in the above solution is greater than the "second preset number", and that the first preset number is 1 and the second preset number is 0. Furthermore, the "determining whether the second in-vehicle screen is the first in-vehicle screen" in the above solution is to determine whether the viewing fields of the target user and the reference user overlap, that is, whether they are viewing the same in-vehicle screen.

[0095] In the above technical solution, when the target user is a rear-seat user, the method determines a first number of target users and a second number of reference users who are not experiencing motion sickness. This allows the determination of the number of rear-seat users viewing the in-vehicle screen and experiencing motion sickness, as well as the number of rear-seat users viewing the in-vehicle screen and not experiencing motion sickness. When the first number is the first preset number and the second number is the second preset number, only the target user is in the rear seat of the vehicle, and the current screen illumination area can be adjusted directly. However, when the first number is the first preset number and the second number is greater than the second preset number, there are also reference users viewing the in-vehicle screen. If the reference users and the target users are viewing the same in-vehicle screen, directly adjusting the current screen illumination area could cause a sudden change in the reference users' viewing field of view, impacting the reference users' viewing experience. When the first number is the first preset number and the second number is greater than the second preset number, the method further determines whether the reference users' viewing fields overlap with the target users'. Only when there is no overlap is the current screen illumination area adjusted. This prevents adjustments to the current screen illumination area from impacting the reference users' in-vehicle experience.

[0096] In one possible implementation, the method 200 also includes: when the second vehicle-mounted screen is the first vehicle-mounted screen, or when the first number is greater than the first preset number, the vehicle controller determines a third vehicle-mounted screen adapted for the target user from multiple vehicle-mounted screens, and the third vehicle-mounted screen does not conflict with the vehicle-mounted screens viewed by other users; the vehicle controller switches the target screen to the third vehicle-mounted screen, and adjusts the occupied area of ​​the second lighting area on the third vehicle-mounted screen to the third occupied area, and adjusts the position of the second lighting area on the third vehicle-mounted screen to the third position, the second lighting area is the display area on the third vehicle-mounted screen for displaying the target screen and the backlight source corresponding to the second lighting area is turned on, the third occupied area is related to the first occupied area, and the third position is related to the first position.

[0097] It should be understood that in the above solution, when a target user and a reference user are viewing the same in-vehicle screen, or when multiple target users are experiencing motion sickness, the target image is uniformly displayed on a third in-vehicle screen. The third in-vehicle screen is positioned in the vehicle so that it is convenient for the aforementioned users (the target user or users) to view the image. In some embodiments, the third in-vehicle screen is a rear-row ceiling screen.

[0098] It should also be understood that the phrase "the third occupied area is related to the first occupied area" in the above solution means that the third occupied area of ​​the second illuminated area on the third vehicle-mounted screen is related to the first occupied area of ​​the picture illuminated area on the first vehicle-mounted screen. The phrase "the third position is related to the first position" means that the third position of the second illuminated area on the third vehicle-mounted screen is consistent with the first position of the picture illuminated area on the first vehicle-mounted screen.

[0099] In the above technical solution, when a target user experiences motion sickness and is viewing the same in-vehicle screen as a reference user, or when multiple target users experience motion sickness, the method determines a third in-vehicle screen suitable for the target user from among the multiple in-vehicle screens, simultaneously switches the target image to the third in-vehicle screen, and adjusts the second illuminated area. This maximizes the matching of the unified in-vehicle screen, not only meeting the target user's viewing needs with minimal screen resources, but also alleviating the target user's motion sickness symptoms.

[0100] In some embodiments, the vehicle controller determines a third vehicle screen adapted for the target user from multiple vehicle screens, including: the vehicle controller displays a third reminder message on the first vehicle screen, the third reminder message being used to remind multiple users to simultaneously watch the target screen through the current screen lighting area or the number of target users in motion sickness is greater than a first preset number, reminding the target user whether to select a vehicle screen from multiple vehicle screens, copying and switching the target screen to the selected vehicle screen, and adjusting the second lighting area for displaying the target screen on the selected vehicle screen; upon receiving a confirmation instruction from the target user for the third reminder message, the vehicle controller displays multiple vehicle screens on the first vehicle screen; in response to the target user's selection operation of the target vehicle screen from the multiple vehicle screens, the vehicle controller determines the target vehicle screen as the third vehicle screen.

[0101] In some embodiments, when the second vehicle-mounted screen is the first vehicle-mounted screen, the vehicle controller determines a third vehicle-mounted screen adapted for the target user from multiple vehicle-mounted screens, including: when the second vehicle-mounted screen is the first vehicle-mounted screen, the vehicle controller determines whether the first number is the first preset number and whether the second number is greater than the second preset number; when the first number is the first preset number and the second number is greater than the second preset number, the vehicle controller determines whether the first vehicle-mounted screen is a rear headrest screen or a rear armrest screen; when the first vehicle-mounted screen is a rear headrest screen or a rear armrest screen, the vehicle controller determines that the third vehicle-mounted screen is a rear ceiling screen; when the first vehicle-mounted screen is a rear ceiling screen, the vehicle controller determines that the third vehicle-mounted screen is a rear headrest screen or a rear armrest screen.

[0102] In some embodiments, when the first number is greater than the first preset number, the vehicle controller determines a third vehicle screen adapted for the target user from multiple vehicle screens, including: when the first number is greater than the first preset number, the vehicle controller determines whether the second number is greater than the second preset number; when the second number is greater than the second preset number, the vehicle controller determines whether the screen type of the first vehicle screen is the same as the screen type of the second vehicle screen; when the screen types are the same, the vehicle controller determines whether the screen type is a rear headrest screen or a rear armrest screen; when the screen type is a rear headrest screen or a rear armrest screen, the vehicle controller determines that the third vehicle screen is a rear ceiling screen; when the screen type is a rear ceiling screen, the vehicle controller determines that the third vehicle screen is a rear headrest screen or a rear armrest screen; when the screen types are different, the vehicle controller determines the idle rear vehicle screen corresponding to the position of the target user as the third vehicle screen.

[0103] It should be understood that the "screen type is the rear headrest screen" in the above scheme can be specifically as follows: the first vehicle-mounted screen and the second vehicle-mounted screen are both left rear headrest screens; or, the first vehicle-mounted screen and the second vehicle-mounted screen are both right rear headrest screens, or, the first vehicle-mounted screen is the left rear headrest screen and the second vehicle-mounted screen is the right rear headrest screen, or, the second vehicle-mounted screen is the left rear headrest screen and the first vehicle-mounted screen is the right rear headrest screen.

[0104] It should also be understood that the "rear-seat screen corresponding to the target user's position" in the above solution refers to the rear-seat screen that is adapted to the target user in terms of viewing distance and angle. For example, if the target user is located on the left side of the rear seat, the rear-seat screen corresponding to the target user's position is the left rear headrest screen, not the right rear headrest screen. Furthermore, "idle" means unused.

[0105] In some embodiments, the method 200 also includes: when the rear-seat car screen corresponding to the target user's position is used by the reference user, the vehicle controller determines whether the rear-seat car screen corresponding to the reference user is in use; when the rear-seat car screen corresponding to the reference user is not in use, the vehicle controller switches the playback screen watched by the reference user to the rear-seat car screen corresponding to the reference user, and determines the rear-seat car screen corresponding to the target user's position as the third car screen.

[0106] The “other display areas on the first in-vehicle screen” are described as follows.

[0107] In one possible implementation, after step 203, the method 200 also includes: the vehicle controller determines the area difference between the display area on the first vehicle screen and the first occupied area; the vehicle controller adjusts the display area corresponding to the area difference on the first vehicle screen to a blackout area, the backlight source corresponding to the blackout area is turned off and the blackout area is not used to display the target screen.

[0108] It should be understood that in the above solution, the "display area on the first vehicle screen" is 1, and the "area difference" can be represented by a percentage. The above solution describes that the currently lit area of ​​the screen occupies a first occupied area (first percentage) on the first vehicle screen, and the unlit area occupies a fourth occupied area (area difference, i.e., second percentage) on the first vehicle screen, and the sum of the first percentage and the second percentage is 1.

[0109] It should also be understood that, generally, the current screen lighting area for displaying the target screen on the first vehicle screen occupies a large area on the first vehicle screen, that is, there is almost no flameout area.

[0110] It should also be understood that the above technical solution can be regarded as switching the image quality of the first vehicle-mounted screen to low motion sickness quality (automatically turning off the local backlight source of the first vehicle-mounted screen to form lit areas and unlit areas of the screen) when the target user is in a motion sickness state.

[0111] In the above technical solution, when the target user is in a state of motion sickness, the method reduces the occupied area of ​​the current screen lighting area used to display the target screen to the first occupied area, and adjusts the position of the current screen lighting area to the first occupied area. In addition, the other display areas on the first vehicle-mounted screen except the current screen lighting area are adjusted to the extinguished area. For the target user, the display area showing the target screen becomes smaller, which can greatly reduce the visual impact on the target user, reduce the focusing effort of the target user's eyes, and thus reduce the fatigue of the eyes. Moreover, the current screen lighting area is surrounded by a black background, which can absorb the brightness of the current screen lighting area, reduce the stimulation of light reflection on the target user's eyes, and thus relieve eye fatigue. In addition, the black background can increase the contrast between the current screen lighting area and the extinguished area, making the target screen clearer and more vivid, making it easier for the target user to identify and understand the target screen, and reducing the visual burden on the eyes.

[0112] Figure 3 This is a schematic diagram of a first vehicle-mounted screen for alleviating motion sickness symptoms provided by an embodiment of the present application.

[0113] For example, the display process of the first in-vehicle screen is described when the target user's eyes are on the left side of the first in-vehicle screen and the target user's motion sickness level is the second level. Figure 3 As shown, the currently lit area of ​​the screen is displayed on the left side of the first vehicle screen, and the area occupied by it on the first vehicle screen is the first occupied area. The other display areas on the first vehicle screen except the currently lit area of ​​the screen are the unlit areas. The backlight corresponding to the currently lit area of ​​the screen is turned on, and the backlight corresponding to the unlit area is turned off.

[0114] In one possible implementation, the method 200 also includes: the vehicle controller determines N brightnesses between the first brightness of the current screen lighting area and the second brightness of the unlit area according to a preset brightness step value, where N is a positive integer greater than or equal to 1; in the unlit area, the vehicle controller determines a candidate display area, which is close to the boundary between the current screen lighting area and the unlit area; the vehicle controller divides the candidate display area into N target display areas in left-right order; the vehicle controller turns on the backlight sources corresponding to the N target display areas, and adjusts the brightness of each target display area in the N target display areas to a corresponding brightness among the N brightnesses.

[0115] It should be understood that the backlight source corresponding to the “off area” in the above solution is turned off, and the second brightness of the off area is 0 cd / m 2 Typically, the brightness range of the display area used to display the image is (100,300) cd / m 2 The first brightness is any brightness within the brightness range.

[0116] In the above technical solution, the method determines a candidate display area in the extinguished area, divides the candidate display area into N target display areas in a left-right order, turns on the backlight sources corresponding to the N target display areas, and adjusts the brightness of each target display area to a brightness corresponding to a first brightness and a second brightness. In other words, the method sets a multi-brightness gradient transition zone between the current display area and the extinguished area according to the actual first brightness of the current display area and the second brightness of the extinguished area. This can avoid the visual impact of the current display area on the target user when the contrast between the lit area and the extinguished area of ​​the current picture is very obvious. The gradient transition zone can act as a buffer, allowing the target user's eyes to gradually adapt to the change in brightness and not feel uncomfortable due to sudden changes in brightness.

[0117] In some embodiments, the vehicle controller determines N brightnesses between the first brightness of the currently lit area of ​​the screen and the second brightness of the unlit area according to a preset brightness step value, including: the vehicle controller determines the brightness difference between the first brightness and the second brightness; the vehicle controller determines the ratio of the brightness difference to the preset brightness step value as a first value; the vehicle controller determines the difference between the first value and the first preset value as the N brightnesses.

[0118] It should be understood that the “first preset value” in the above solution is 1.

[0119] In some embodiments, the first brightness is 200, the second brightness is 0, the preset brightness step value is 50, and three brightnesses can be determined, specifically 150, 100, and 50.

[0120] In some embodiments, in the blackout area, the vehicle controller determines the candidate display area, including: the vehicle controller obtains the duration of the target user watching the first vehicle-mounted screen; the vehicle controller determines the ratio of the duration to the total time of using the first vehicle-mounted screen as a second value; when the second value is less than a second preset value, the vehicle controller determines the product of the second value and the length of the blackout area as the first length; the vehicle controller determines the candidate display area in the blackout area based on the first length and the width of the blackout area; when the second value is greater than the second preset value, the vehicle controller determines the candidate display area in the blackout area based on the second length and the width of the blackout area, the second length being the product of a third value and the length of the blackout area, and the third value being the difference between the second value and the second preset value.

[0121] It should be understood that the "second preset value" in the above solution refers to the maximum percentage that can alleviate the visual impact of strong contrast on multiple users. In some embodiments, the second preset value is 50%.

[0122] Figure 4 This is a schematic diagram of another embodiment of the present application showing a first vehicle-mounted screen for alleviating motion sickness symptoms.

[0123] For example, the display process of the first in-vehicle screen is described when the target user's eyes are on the left side of the first in-vehicle screen and the target user's motion sickness level is the second level. Figure 4 As shown, the current screen lighting area is displayed on the left side of the first vehicle screen, and its occupied area on the first vehicle screen is the first occupied area. Figure 4 The black display area in the image is the off area. A gradient transition area is set between the current screen lit area and the off area (see Figure 4 The backlight corresponding to the currently lit area of ​​the image is turned on, the backlight corresponding to the unlit area is turned off, and the backlight corresponding to the gradual transition area is turned on. Figure 4 The gradient transition area set in includes three target display areas, and the brightness of the three target display areas gradually changes from bright to dark from left to right.

[0124] In some embodiments, the method 200 also includes: the vehicle controller restores the first occupied area of ​​the current screen lighting area to the original current occupied area, and restores the first position of the current screen lighting area to the original current position in response to the target user's triggering operation on the target control on the first vehicle-mounted screen. The target control is used to exit the adjustment process of the current screen lighting area so that the occupied area and position of the current screen lighting area on the first vehicle-mounted screen are restored to the original settings; or, when the target user changes from a motion sickness state to a non-motion sickness state, the vehicle controller restores the first occupied area of ​​the current screen lighting area to the original current occupied area, and restores the first position of the current screen lighting area to the original current position.

[0125] It should be understood that in other cases, the vehicle controller may also restore the first occupied area of ​​the current screen lighting area to the original current occupied area, and restore the first position of the current screen lighting area to the original current position (exiting low-halo quality). For example, when the first vehicle screen needs to display information that affects vehicle safety or driving safety, the vehicle controller controls the first vehicle screen to exit low-halo quality.

[0126] Figure 5 It is a structural diagram of a screen control device provided in an embodiment of the present application.

[0127] For example, Figure 5 As shown, the apparatus 500 includes:

[0128] The determination module 501 is configured to:
