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 audience of vehicles is becoming more and more extensive. However, there are also more and more vehicle-related problems, including motion sickness of users during driving.

[0003] In some scenarios, users need to work or entertain through the in-vehicle screen 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 in users.

[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 viewing needs of a target user for a vehicle-mounted screen in a vehicle 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 at 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 a current occupied area of ​​a current picture lighting area on the first vehicle-mounted screen, and adjusting a 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 a driving state and the target user in the vehicle must watch the target picture through the first vehicle-mounted screen, if the target user has motion sickness symptoms, the vehicle in the method can reduce the current occupied area of ​​the picture lighting area on the first vehicle-mounted screen for displaying the target picture, and adjust the current position of the picture lighting area on the first vehicle-mounted screen. In other words, the backlight source corresponding to the picture lighting area is turned on, and the area of ​​the picture lighting area watched by the target user becomes smaller, which will occupy less visual space, increase the contrast between the picture 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 picture lighting area watched by the target user is adjusted to the first position adapted to the target user, which can avoid the target user from tilting his head or neck excessively, help keep the head stable, and reduce the stimulation of the vestibular system of the target user. Therefore, the method can alleviate the motion sickness symptoms of the target user and can also meet the viewing needs of the target user for the first vehicle-mounted screen in the car.

[0008] In combination with the first aspect, in certain possible implementations, determining the target control parameters includes any one of the following: in response to the target user clicking a 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 the first position in the parameter configuration list displayed on the first vehicle screen by clicking the parameter configuration control on the first vehicle screen. In this way, the target user can customize the screen lighting area based on his own motion sickness needs, so that not only the control parameters that can alleviate the target user's motion sickness symptoms can be determined, but also the preferences of the target user can be fully considered, which can improve the target user's car experience. Furthermore, the method can directly determine the first occupied area based on the target user's motion sickness level, and determine the first position based on the target user's eye position. In this way, the way of adaptively controlling the screen lighting area according to the actual motion sickness state of the target user can avoid the situation where the target user does not respond to the parameter configuration control and cannot determine the target control parameter. At the same time, target users with different motion sickness levels can obtain the first occupied area adapted to them, which can be accurately adjusted according to the individual's motion sickness condition. For example, when the motion sickness level is high, the screen lighting area only occupies a small part, which can reduce the switching of visual scenes and the visual impact of dynamic pictures. In addition, determining the first position based on the target user's eye position can ensure that the target user views the target picture 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 picture lighting area used to display the target picture to the first occupied area, and adjusts the position of the current picture lighting area to the first occupied area. In addition, other display areas on the first vehicle-mounted screen except the current picture lighting area are adjusted to the extinguished area. For the target user, the display area showing the target picture becomes smaller, which can greatly reduce the visual impact on the target user and reduce the focusing effort of the target user's eyes, thereby reducing eye fatigue. In addition, the current picture lighting area is surrounded by a black background, which can absorb the brightness of the current picture lighting area, reduce the stimulation of light reflection to the target user's eyes, and thus relieve eye fatigue. In addition, the black background can increase the contrast between the current picture lighting area and the extinguished area, making the target picture clearer and more vivid, and the target user can more easily identify and understand the target picture, 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 candidate display area 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 the first brightness and the 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 current lit area and the extinguished area is very obvious. The gradient transition zone can play a buffering role, so that the eyes of the target user can gradually adapt to the change in brightness and will 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 picture lighting area on the first vehicle-mounted screen is reduced, and the current position of the current picture lighting area on the first vehicle-mounted screen is adjusted, including: when the target user is the co-pilot user in the vehicle, determining whether the first vehicle-mounted screen is the co-pilot ceiling screen in the vehicle; when the first vehicle-mounted screen is the co-pilot ceiling screen, based on the target control parameters, the current occupied area is reduced, and the current position is adjusted.

[0015] In the above technical solution, when the target user is the co-pilot user and the first vehicle-mounted screen is the co-pilot ceiling screen, the co-pilot user'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, reduce the current occupied area of ​​the current screen lighting area to the first occupied area, and adjust the current position of the current screen lighting area to the first position. In this way, the method can not only consider the impact of the change of the display parameters of the current screen lighting area on other users (drivers) to avoid traffic accidents, but also alleviate the motion sickness symptoms of the co-pilot user to the greatest extent.

[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 a co-pilot entertainment screen in the vehicle, determining 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, based on the target control parameters, reducing the current occupied area and adjusting the current position; when the target screen is the preset display screen, copying the target screen and switching it to the co-pilot ceiling screen, and at the same time adjusting the occupied area of ​​the first lit area on the co-pilot ceiling screen to the second occupied area, and adjusting the position of the first lit area on the co-pilot ceiling screen to the second position, the first lit area is the display area on the co-pilot ceiling screen for displaying the target screen and the backlight source corresponding to the first lit 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, the driver will be lost 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 picture lighting area on the first vehicle-mounted screen is reduced, and the current position of the current picture 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 the first number of target users and the second number of reference users who are not in a motion sickness state. This can obtain the number of rear-seat users who are watching the in-vehicle screen and are motion sickness, and the number of rear-seat users who are watching the in-vehicle screen and are not motion sickness. When the first number is the first preset number and the second number is the second preset number, there are only target users in the back row of the vehicle, and the current screen lighting area can be adjusted directly. 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 watching the in-vehicle screen in the vehicle. If the reference user and the target user watch the same in-vehicle screen, directly adjusting the current screen lighting area will cause a sudden change in the viewing field of the reference user, affecting the viewing experience of the reference user, etc. When the first number is the first preset number and the second number is greater than the second preset number, the method further judges whether the viewing fields of the reference user and the target user overlap, and only when there is no overlap, the current screen lighting area is adjusted. This can avoid affecting the reference user's car experience when adjusting the current screen lighting area.

[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 there is no conflict between the third vehicle-mounted screen and 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 is in a state of motion sickness and the target user and the reference user watch the same in-vehicle screen, or when multiple target users are in a state of motion sickness, the method determines a third in-vehicle screen adapted to the target user from multiple in-vehicle screens, switches the target screen to the third in-vehicle screen, and adjusts the second lighting area. This can maximize the matching of a unified in-vehicle screen, not only can it meet the target user's needs for watching the in-vehicle screen with the least screen resources, but also can alleviate the target user's motion sickness symptoms.

[0022] In a second aspect, a screen control device is provided, which includes: a determination module, used to: 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, determine whether the target user is in a motion sickness state; when the target user is in a motion sickness state, determine 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 at 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; an adjustment module, used to reduce a current occupied area of ​​a current picture lighting area on the first vehicle-mounted screen and adjust a current position of the current picture lighting area on the first vehicle-mounted screen based on the target control parameter.

[0023] In combination with the second aspect, in some possible implementations, the device also includes: a display module, used to display 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, and 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, and 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, and the target user's eye position corresponds to the first position.

[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 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 will be combined with the accompanying drawings to clearly and thoroughly describe the technical solutions in this application. 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 of associated 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 are not to be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0040] Figure 1 It is a schematic diagram of a scenario of using a vehicle 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 affairs through the on-board screen in vehicle A due to various emergencies. This may be due to fierce market competition, requiring the business owner to make decisions immediately; or there may be a sudden change in customer demand, and the business owner needs to adjust the plan quickly.

[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, the present application provides a screen control method to meet the user's viewing needs for the vehicle 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 It is a schematic flow chart 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 the following Figure 1 The vehicle shown (eg, vehicle A). Specifically, the screen control method can be applied to a 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 picture 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 vehicle screen" in the above step 201 is any vehicle screen in the vehicle that can provide entertainment functions and work needs for the target user. In some embodiments, the first vehicle screen is any one of the passenger entertainment screen, the rear seat back screen, the passenger ceiling screen, and the 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-row user or the back-row user in the vehicle, after the target user watches the target picture played on the first vehicle-mounted screen for a long time, the target user will suffer from motion sickness. Specifically, for the front-row user, watching the target picture for a long time will cause the neck muscles to continuously contract, resulting in compression of the blood vessels in the neck, thereby reducing the blood supply to the brain tissue, which may cause symptoms of motion sickness. However, the front-row user has a wider field of vision, and is less likely to suffer from motion sickness than the back-row user. For the back-row user, the back-row user cannot see the road ahead, which means that the back-row user lacks the first visual information about how the vehicle moves. In this case, there is a difference between the motion state perceived by the body and the position information perceived by the vision, and this difference will stimulate the vestibular organs of the back-row user, which will increase the probability of the back-row user being in a state of motion sickness.

[0051] It should also be understood that when the target user is in a motion sickness state in the above step 201, the target user may experience the following symptoms, including drowsiness (closing eyes and opening mouth and nodding frequently and bloodshot eyes and tears in eyes), nausea, vomiting, dizziness, headache, cold sweat, pale face, tinnitus and stuffy ears, etc. When the vehicle is driving on a bumpy road, or the driving mode of the vehicle is the target driving mode (the target driving mode is used to affect the stability of the vehicle when driving), or the number of brakes of the vehicle is large, the target user who watches the target screen 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 screen should be at the first occupied area and the first position of the first vehicle 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 characterized 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 "picture lighting area" in the above step 202 (the light source behind the picture lighting area in the first vehicle-mounted screen) is turned on. The turned-on backlight source can ensure that the picture lighting area displays the target picture with a certain brightness, and can improve the contrast between the picture lighting area and other display areas.

[0055] In some embodiments, the first occupied area is characterized 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 that “the target user is in a motion sickness state” is described as follows.

[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 for alleviating the target user's motion sickness symptoms. In some embodiments, the target user triggers the anti-motion sickness mode by voice; or, the target user triggers the anti-motion sickness mode by clicking an anti-motion sickness button in the vehicle, which is a physical button or a virtual button on the vehicle screen; or, the target user triggers the anti-motion sickness mode by an anti-motion sickness gesture, which is a gesture of opening the palm.

[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 stability 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 sports 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 duration; 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 as follows.

[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 scheme, 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, and the parameter configuration control is used to control the display of a parameter configuration list, and the parameter configuration list 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 "target user's motion sickness level is negatively correlated with 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; the higher the motion sickness level, the smaller the first occupied area. However, 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, and the preset occupied area does not affect the target user from reading information from the screen lit area.

[0070] It should also be understood that "the eye position of the target user 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 the first position in the parameter configuration list displayed on the first vehicle screen by clicking the parameter configuration control on the first vehicle screen. In this way, the target user can customize the screen lighting area based on his own motion sickness needs, so that not only the control parameters that can alleviate the target user's motion sickness symptoms can be determined, but also the preferences of the target user can be fully considered, which can improve the target user's car experience. Furthermore, the method can directly determine the first occupied area based on the target user's motion sickness level, and determine the first position based on the target user's eye position. In this way, the way of adaptively controlling the screen lighting area according to the actual motion sickness state of the target user can avoid the situation where the target user does not respond to the parameter configuration control and cannot determine the target control parameter. At the same time, target users with different motion sickness levels can obtain the first occupied area adapted to them, which can be accurately adjusted according to the individual's motion sickness condition. For example, when the motion sickness level is high, the screen lighting area only occupies a small part, which can reduce the switching of visual scenes and the visual impact of dynamic pictures. In addition, determining the first position based on the target user's eye position can ensure that the target user views the target picture 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 to display the continuous 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 a first level, the vehicle controller determines the first occupied area as a first area percentage; when the motion sickness level is a second level, the vehicle controller determines the first occupied area as a second area percentage; when the motion sickness level is a 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 eyes of the target user may also be in other positions relative to the first vehicle-mounted screen. In the above scheme, only the above positions (such as the eyes being in the middle of the first vehicle-mounted screen, etc.) are described by way of example, and the situation where the eyes are in other positions relative to the first vehicle-mounted screen is similar to the above examples and will not be described in detail here.

[0076] 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 not to adjust the current screen lighting area is received, 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 as follows.

[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 front passenger user in the vehicle, the vehicle controller determines whether the first vehicle-mounted screen is the front passenger ceiling screen in the vehicle; when the first vehicle-mounted screen is the front passenger 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 solution, 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, the viewing behavior of the passenger seat user has no essential connection with whether the driver can drive the vehicle safely. For example, the driver will not obtain navigation information through the passenger seat ceiling screen.

[0084] In the above technical solution, when the target user is the co-pilot user and the first vehicle-mounted screen is the co-pilot ceiling screen, the co-pilot user'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, reduce the current occupied area of ​​the current screen lighting area to the first occupied area, and adjust the current position of the current screen lighting area to the first position. In this way, the method can not only consider the impact of the change of the display parameters of the current screen lighting area on other users (drivers) to avoid traffic accidents, but also alleviate the motion sickness symptoms of the co-pilot user to the greatest extent.

[0085] In one possible implementation, the method 200 also includes: when the first vehicle-mounted screen is a co-pilot 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 co-pilot ceiling screen, and at the same time adjusts the occupied area of ​​the first lit area on the co-pilot ceiling screen to the second occupied area, and adjusts the position of the first lit area on the co-pilot ceiling screen to the second position, the first lit area is the display area on the co-pilot ceiling screen for displaying the target screen and the backlight source corresponding to the first lit 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 screen through the passenger seat entertainment screen, the target screen may be the driving content required by the driver, such as navigation information or 360-degree reversing images. The driver needs to assist in safe driving based on the driving content. Therefore, the process of adjusting the current display area also needs to give priority to analyzing the target screen.

[0087] It should also be understood that in the above scheme, when the target screen displayed on the current display area of ​​the co-pilot entertainment screen is the preset display screen, in order to alleviate the co-pilot user's motion sickness symptoms and not affect the driver's need to obtain driving content, the target screen can be copied and switched to the co-pilot ceiling screen. At this time, the driver can also obtain driving content through the co-pilot entertainment screen, and the co-pilot user can also watch the target screen, and alleviate the co-pilot user's motion sickness symptoms.

[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 co-pilot 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 co-pilot 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 co-pilot ceiling screen. For another example, the current picture lighting area is in the right position on the first vehicle-mounted screen, and the first lighting area is in the right position on the co-pilot 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, the driver will be lost 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 and switches the target screen to the passenger ceiling screen, and 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 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 not receiving a confirmation instruction from the target user for the second reminder information, or when receiving an instruction 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, the reference users being rear-seat users and watching a 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 the first preset number is 1, and the second preset number is 0. In addition, the "determining whether the second vehicle-mounted screen is the first vehicle-mounted 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 vehicle-mounted screen.

[0095] In the above technical solution, when the target user is a rear-seat user, the method determines the first number of target users and the second number of reference users who are not in a motion sickness state. This can obtain the number of rear-seat users who are watching the in-vehicle screen and are motion sickness, and the number of rear-seat users who are watching the in-vehicle screen and are not motion sickness. When the first number is the first preset number and the second number is the second preset number, there are only target users in the back row of the vehicle, and the current screen lighting area can be adjusted directly. 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 watching the in-vehicle screen in the vehicle. If the reference user and the target user watch the same in-vehicle screen, directly adjusting the current screen lighting area will cause a sudden change in the viewing field of the reference user, affecting the viewing experience of the reference user, etc. When the first number is the first preset number and the second number is greater than the second preset number, the method further judges whether the viewing fields of the reference user and the target user overlap, and only when there is no overlap, the current screen lighting area is adjusted. This can avoid affecting the reference user's car experience when adjusting the current screen lighting area.

[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 there is no conflict between the third vehicle-mounted screen and 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 scheme, when a target user and a reference user watch the same in-vehicle screen, or when multiple target users are in a state of motion sickness, the target screen is uniformly displayed through a third in-vehicle screen. The position of the third in-vehicle screen in the vehicle is a position convenient for the above-mentioned users (a target user or multiple target users) to watch. In some embodiments, the third in-vehicle screen is a rear ceiling screen.

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

[0099] In the above technical solution, when a target user is in a state of motion sickness and the target user and the reference user watch the same in-vehicle screen, or when multiple target users are in a state of motion sickness, the method determines a third in-vehicle screen adapted to the target user from multiple in-vehicle screens, switches the target screen to the third in-vehicle screen, and adjusts the second lighting area. This can maximize the matching of a unified in-vehicle screen, not only can it meet the target user's needs for watching the in-vehicle screen with the least screen resources, but also can alleviate 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 that the number of target users in a motion sickness state is greater than a first preset number, reminding the target user whether to select a vehicle screen from multiple vehicle screens, and 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 among 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-side rear headrest screens; or, the first vehicle-mounted screen and the second vehicle-mounted screen are both right-side rear headrest screens, or, the first vehicle-mounted screen is the left-side rear headrest screen and the second vehicle-mounted screen is the right-side rear headrest screen, or, the second vehicle-mounted screen is the left-side rear headrest screen and the first vehicle-mounted screen is the right-side rear headrest screen.

[0104] It should also be understood that the "rear-row car screen corresponding to the position of the target user" in the above solution refers to the rear-row car screen that is adapted to the target user in terms of viewing distance and viewing angle. For example, if the position of the target user is the left rear row, the rear-row car screen corresponding to the position of the target user is the left rear headrest screen, not the right rear headrest screen. In addition, "idle" means not being used.

[0105] In some embodiments, the method 200 also includes: when the rear-seat vehicle screen corresponding to the position of the target user is used by the reference user, the vehicle controller determines whether the rear-seat vehicle screen corresponding to the reference user is in use; when the rear-seat vehicle screen corresponding to the reference user is not in use, the vehicle controller switches the playback picture watched by the reference user to the rear-seat vehicle screen corresponding to the reference user, and determines the rear-seat vehicle screen corresponding to the position of the target user as the third vehicle 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 scheme, the "display area on the first vehicle screen" is 1, and the "area difference" can be represented by a percentage. The above scheme describes that the current screen lit area occupies the first occupied area (first percentage) on the first vehicle screen, and the extinguished area occupies the 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, usually, the current screen lighting area on the first vehicle-mounted screen for displaying the target screen occupies a large area on the first vehicle-mounted 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 a lit area and an unlit area of ​​the picture) 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 picture lighting area used to display the target picture to the first occupied area, and adjusts the position of the current picture lighting area to the first occupied area. In addition, other display areas on the first vehicle-mounted screen except the current picture lighting area are adjusted to the extinguished area. For the target user, the display area showing the target picture becomes smaller, which can greatly reduce the visual impact on the target user and reduce the focusing effort of the target user's eyes, thereby reducing eye fatigue. In addition, the current picture lighting area is surrounded by a black background, which can absorb the brightness of the current picture lighting area, reduce the stimulation of light reflection to the target user's eyes, and thus relieve eye fatigue. In addition, the black background can increase the contrast between the current picture lighting area and the extinguished area, making the target picture clearer and more vivid, and the target user can more easily identify and understand the target picture, reducing the visual burden on the eyes.

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

[0113] Exemplarily, 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 current picture light-on 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, and other display areas on the first vehicle screen except the current picture light-on area are the black-out areas. Among them, the backlight source corresponding to the current picture light-on area is turned on, and the backlight source corresponding to the black-out area is turned off.

[0114] In a 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 of 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 "extinguished area" in the above solution is turned off, and the second brightness of the extinguished 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 in 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 the first brightness and the 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 current lit area and the extinguished area is very obvious. The gradient transition zone can play a buffering role, so that the eyes of the target user can gradually adapt to the change in brightness and will 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 a candidate display area, including: the vehicle controller obtains the duration of the target user viewing 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 first vehicle-mounted screen for alleviating motion sickness symptoms provided by an embodiment of the present application.

[0123] Exemplarily, 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 light 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 gradual 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 responds to the target user's triggering operation of the target control on the first vehicle-mounted screen, restoring the first occupied area of ​​the current screen lighting area to the original current occupied area, and restoring the first position of the current screen lighting area to the original current position, and the target control is used to exit the adjustment process of the current screen lighting area to restore the occupied area and position of the current screen lighting area on the first vehicle-mounted screen 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 (exit low-halo quality). For example, when the first vehicle screen needs to display information that affects vehicle safety and driving safety, the vehicle controller controls the first vehicle screen to exit low-halo quality.

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

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