[0055] The control method, device and equipment of the vehicle display screen provided by the embodiment of the present invention take into account the different angles between the sight lines and the screen of drivers of different heights, resulting in different perception differences of the reflection of the vehicle display screen by drivers of different heights.

Therefore, when controlling the vehicle display screen, it can first be determined whether the driver is disturbed by the reflection according to the driver's eyeball position, the direction of the sight line and the frequency of the driver viewing the vehicle display screen. If so, an adjustment angle of the vehicle display screen, i.e., the target angle, is calculated according to the driver's eyeball position information, and adjusted to reduce the impact of the screen reflection on the driver's sight line, help the driver keep his sight focused, reduce visual fatigue, and improve the comfort and safety during long-term driving.

[0056] The above description is only an overview of the technical solution of the embodiment of the present invention.

In order to make the above and other purposes, features and advantages of the embodiment of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are listed below.

[0063] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0064] In the prior art, in order to reduce the reflection effect of the vehicle display screen, the brightness adjustment method is usually adopted to adapt to the changes in ambient light. The ambient light sensor installed in the vehicle detects the lighting conditions inside and outside the vehicle in real time, and automatically adjusts the brightness of the display screen according to these conditions, thereby reducing the interference of reflection on the driver's vision. Specifically, when the vehicle is in a direct sunlight environment, the ambient light sensor will detect high-intensity lighting conditions, and automatically increase the brightness of the vehicle display screen to make the display area of ​​the screen content clearer, so that the contrast between the reflective area and the display area is greater, and the reading difficulty and blurred vision caused by the reflection effect are reduced; in darker environments (such as driving at night), the brightness of the vehicle display screen is automatically reduced to reduce the excessive reflection of the light of the vehicle display screen into the driver's eyes, avoid glare, and prevent visual fatigue caused by the vehicle display screen being too bright.

[0065] However, when light enters the car at a specific angle and reflects onto the display screen, simply adjusting the brightness of the car display screen cannot completely eliminate the glare caused by the reflected light to the driver, so the effect of reducing reflections is limited. In addition, during the driving process, the reflection of the car display screen may distract the driver's attention and increase driving risks.

[0066] Based on this, the present invention proposes a control method, device and equipment for a vehicle-mounted display screen. Considering that the reason for the reflection of the vehicle-mounted display screen is mainly due to the fact that the sight lines of different drivers and the angle of the vehicle-mounted display screen easily form a reflection path, the perception difference of the reflection of the vehicle-mounted display screen by drivers of different heights is also different. For example, the eyeball position of a tall driver is higher, so the sight line height is higher and closer to the horizontal position of the vehicle-mounted display screen, resulting in a smaller angle between the screen and the sight line, and the problem of reflection in the upper part of the screen is prone to occur; while the eyeball position of a short driver is lower, so the sight line height is lower, closer to the middle position of the vehicle-mounted display screen, resulting in a larger angle between the screen and the sight line, and the problem of reflection in the middle of the screen is prone to occur. Therefore, when controlling the vehicle-mounted display screen, it can be first determined whether the driver is disturbed by the reflection according to the driver's eyeball position, sight line direction and the frequency of the driver viewing the vehicle-mounted display screen. If so, according to the driver's eyeball position information, an adjustment angle of the vehicle-mounted display screen, i.e., the target angle, is calculated and adjusted to reduce the impact of screen reflection on the driver's sight line, help the driver keep his sight focused, reduce visual fatigue, and improve the comfort and safety during long-term driving.

[0067] Figure 1 The structure diagram of the control system of the vehicle display screen provided by the present invention is shown as follows: Figure 1 As shown, the system includes: a vision protection system, an energy consumption control system, and a safety protection system.

[0068] Among them, the vision protection system includes an eye tracking module, a vision protection module, and an eye protection mode control module. Specifically, the eye tracking module uses a high-precision camera installed in the car to monitor the occupant's eye position and gaze point in real time to assess eye fatigue and long-term visual concentration; the vision protection algorithm runs in the software, analyzes the camera data, identifies situations that require vision protection (such as long-term fixed viewing) and implements corresponding measures; the eye protection mode control module dynamically adjusts the brightness, color temperature, and blue light level of the vehicle display according to the system's commands, and even activates a mandatory rest reminder to protect the passenger's eyesight.

[0069] The energy consumption control system includes an intelligent screen activation / sleep module and an environmental sensing adjustment module. Specifically, the intelligent screen activation / sleep module intelligently decides whether to wake up or shut down the vehicle display screen based on the data from the eye tracking module, thereby reducing the power consumption of the vehicle display screen during non-viewing time; the environmental sensing adjustment module obtains the light conditions inside and outside the vehicle through the ambient light sensor, and automatically adjusts the brightness of the vehicle display screen to meet visual needs while reducing energy consumption.

[0070] The safety protection system includes a driving protection module and an anti-glare module. Specifically, in non-emergency situations, when the driving protection module detects that the driver is overly distracted by the on-board display screen, it will reduce or suspend the information push to the driver's related screens to avoid distraction while driving; further, in emergency situations, that is, using the vehicle's sensors to determine that there is a potential collision risk ahead, etc., it will temporarily turn off non-critical on-board displays and use warning sounds or voice prompts to focus on driving conditions until the safety risk is eliminated. The anti-glare module can intelligently adjust the brightness and angle of the on-board display screen to reduce the interference of screen reflections on the driver's vision at night or in strong light environments.

[0071] Figure 2 The schematic diagram shows the process of the control method of the vehicle display screen provided by the present invention. Figure 1 ,like Figure 2 As shown, the method comprises the following steps:

[0072] Step 201: Determine the driver's gaze point based on the driver's eye activity data.

[0073] Among them, the eye activity data includes the driver's target eye position and line of sight direction.

[0074] It is understandable that through the high-precision camera installed in the car, the driver's target eye position and line of sight direction can be monitored in real time to determine whether the driver's gaze is on the on-board display screen. In this way, the driver's gaze point can be accurately obtained, and it can be accurately judged whether the driver is looking at the on-board display screen, providing a basis for subsequent dynamic adjustment of the on-board display screen.

[0075] Step 202: Determine the frequency of the driver viewing the vehicle display screen according to the gaze point.

[0076] Among them, the vehicle display screen can be a central control display screen, an instrument panel display screen, a co-pilot display screen, etc. In actual applications, for all display screens in the car, it is necessary to obtain and determine the frequency of the driver viewing the vehicle display screen in order to accurately adjust the vehicle display screen.

[0077] It is understandable that after determining the driver's gaze point, it is also necessary to determine the frequency with which the driver views each on-board display screen to determine whether the driver is stimulated by the reflection of the on-board display screen, resulting in an inability to see the display content of the on-board display screen clearly, affecting driving safety.

[0078] Step 203: If the frequency is greater than the preset frequency, the target angle is determined according to the target eye position.

[0079] Among them, the preset frequency can set the corresponding viewing frequency threshold according to the driver's driving habits, safety standards and the type of display screen, or it can be obtained according to industry standards or historical data. The embodiment of the present invention does not make specific restrictions here.

[0080] Among them, compared with the current angle of the vehicle display screen, the reflection effect of the vehicle display screen on the driver is reduced when the vehicle display screen is at the target angle.

[0081] It is understandable that by real-time monitoring and recording the driver's gaze point and the frequency of viewing the vehicle display screen, and comparing it with the preset frequency, if it is detected that the driver's viewing frequency of the vehicle display screen exceeds the preset threshold, it indicates that the driver may be affected by the reflection of the vehicle display screen and cannot accurately obtain the screen information of the vehicle display screen. The vehicle display screen needs to be adjusted to eliminate the impact of the reflection of the vehicle display screen on the driver and reduce the risk of distraction of the driver's attention.

[0082] In a possible implementation, the target angle can be determined based on the target eye position and the first mapping relationship. The first mapping relationship is used to indicate the correspondence between the eye position and the angle. Specifically, the first mapping relationship can be a correspondence between eye coordinates and angles, and the target angle corresponding to the target eye position can be directly determined from the first mapping relationship. The first mapping relationship can also be a correspondence between an eye coordinate interval and an angle, and the target eye coordinate interval can be first determined from the first mapping relationship based on the target eye position, and then the target angle corresponding to the target eye coordinate interval can be determined.

[0083] Step 204: Adjust the vehicle display screen to a target angle.

[0084] It is understandable that by adjusting the car display screen to an angle that matches the driver's line of sight and ensuring that the information on the car display screen can be clearly read by the driver under various lighting conditions, the driver's line of sight deviation caused by frequent checking of the car display screen can be significantly reduced, thereby improving driving safety and reducing the risk of traffic accidents.

[0085] The control method of the vehicle display screen provided by the embodiment of the present invention first determines the driver's gaze point according to the driver's eye position and line of sight direction; then determines whether the driver is disturbed by reflections in combination with the gaze point and the frequency with which the driver checks the vehicle display screen; if so, calculates an adjustment angle of the vehicle display screen, i.e., a target angle, based on the driver's eye position information, and makes adjustments to reduce the impact of screen reflections on the driver's line of sight, ensuring that the information on the vehicle display screen can be clearly read by the driver under various lighting conditions, further helping the driver to keep his line of sight focused, reducing visual fatigue, and improving comfort and safety during long-term driving.

[0086] It should be noted that when determining the target angle that needs to be adjusted for the vehicle display screen based on the target eye position, the target angle can also be calculated in combination with different environments, such as the external brightness of the vehicle.

[0087] In a possible implementation, the specific process of calculating the target angle may include:

[0088] Determine the target angle based on the target eye position and the brightness outside the target vehicle.

[0089] It should be noted that there is a second mapping relationship between the eyeball position, the brightness outside the vehicle, and the angle. In actual use, the target eyeball position and the target brightness outside the vehicle can be used to find the target angle corresponding to the target eyeball position and the target brightness outside the vehicle in the second mapping relationship, so as to determine the optimal display angle of the vehicle display in different environments, thereby ensuring that the driver can clearly view the screen content.

[0090] It should be understood that the optimal display angle of the screen in different environments, ie, the target angle, can be determined based on the target eyeball position, the target exterior brightness, and the second mapping relationship.

[0091] In another achievable manner, the specific process of determining the target angle according to the target eyeball position and the target vehicle exterior brightness may also include:

[0092] First, the target reflectivity of the vehicle display screen is determined according to the target eyeball position and the target exterior brightness of the vehicle; then, the target angle is determined according to the target reflectivity and the mapping relationship.

[0093] The mapping relationship includes the corresponding relationship between reflectivity and angle. The reflectivity can first determine the first reflectivity according to the target eyeball position and the first reflectivity mapping relationship; then, determine the second reflectivity according to the target vehicle exterior brightness and the second reflectivity mapping relationship; finally, the reflectivity of the final vehicle display screen is obtained by weighting the first reflectivity and the second reflectivity.

[0094] It should be understood that the first reflective mapping relationship is used to indicate the correspondence between the eyeball position and the reflectivity, and the second reflective mapping relationship is used to indicate the correspondence between the brightness outside the vehicle and the reflectivity.

[0095] For example, at night, since the eye position directly determines the size of the reflective area, the weight of the first reflectivity determined by the eye position is 0.7, and the influence of the exterior brightness on the reflection is small, so the weight of the second reflectivity determined by the exterior brightness is 0.3. On this basis, the first reflectivity calculated according to the target eye position is 70, and the second reflectivity calculated according to the target exterior brightness is 50, then the target reflectivity can be calculated as follows:

[0096] Target reflectivity = 0.7*70+0.3*50=60

[0097] It should be noted that the weight of the first reflectivity and the weight of the second reflectivity can be set differently according to different environmental conditions. For example, because the brightness outside the car is usually high during daytime driving, the external light easily produces strong reflections on the display screen, so the brightness outside the car has a greater impact on the reflectivity. The weight of the second reflectivity can be increased and the weight of the first reflectivity can be reduced. In this way, different driving scenarios can be responded to more flexibly, ensuring that the adjustment effect of the vehicle display is maximized, effectively improving the driver's driving experience, reducing fatigue and visual interference, and enhancing driving safety.

[0098] It is understandable that since the excessive brightness outside the vehicle will cause the vehicle display screen to reflect, the size of the reflectivity is different for the adjustment size of the target angle, so it is also necessary to find the target first reflectivity corresponding to the target eye position in the first reflectivity mapping relationship according to the target eye position; then, find the target second reflectivity corresponding to the target vehicle brightness in the second reflectivity mapping relationship according to the target vehicle brightness; then, obtain the target reflectivity by weighting the target first reflectivity and the target second reflectivity; finally, according to the target reflectivity and the mapping relationship, that is, using the target reflectivity to find the target angle corresponding to the target reflectivity in the mapping relationship, determine the angle that the vehicle display screen needs to be adjusted. This method takes into account the two major factors of eye position and vehicle brightness, and by calculating multiple reflectivities and performing weighted processing, it can more accurately determine the optimal vehicle display screen angle, effectively reduce reflection problems, and ensure that the display content of the vehicle display screen is clearly visible under various lighting conditions.

[0099] Optionally, due to changes in the vehicle's external brightness, the default brightness of the screen may reduce the driver's visual comfort, so the screen brightness needs to be adjusted. The specific process includes:

[0100] First, the target display screen brightness is determined according to the target eyeball position and the target vehicle exterior brightness; then, the vehicle display is adjusted to the target display screen brightness.

[0101] The brightness of the vehicle display is adjusted intelligently through the ambient light sensor in the energy consumption control system. For example, the brightness is increased during the day or in a bright light environment, and reduced at night or in a dark environment.

[0102] Specifically, after the target reflectivity is determined according to the target eyeball position and the target exterior brightness of the vehicle, the target display screen brightness is determined according to the target reflectivity and the third mapping relationship. The third mapping relationship is used to indicate the mapping relationship between reflectivity and display screen brightness, that is, the target reflectivity is used to find the target display screen brightness corresponding to the target reflectivity in the third mapping relationship; then, while the vehicle display screen is adjusted to the target angle, the vehicle display screen is adjusted to the target display screen brightness, that is, the screen brightness is adjusted to a level suitable for driving and without generating reflections. Furthermore, in extreme cases, if it is determined that the screen reflection seriously threatens driving safety and cannot be resolved by adjusting the brightness or angle, the screen will be automatically turned off to prioritize driving safety.

[0103] Optionally, the target display screen brightness may also be determined according to the target vehicle exterior brightness and a fourth mapping relationship, wherein the fourth mapping relationship is used to indicate the correspondence between the vehicle exterior brightness and the screen brightness.

[0104] Optionally, the target display screen brightness can also be determined according to the target vehicle exterior brightness, the target eyeball position and a fifth mapping relationship, wherein the fifth mapping relationship is used to indicate the correspondence between the vehicle exterior brightness, the eyeball position and the screen brightness.

[0105] Optionally, in addition to adjusting the angle of the display screen according to the frequency with which the driver views the vehicle display screen to reduce the number of times the driver deviates from the driving line of sight, irrelevant information can also be reduced in the display screen to help the driver obtain information accurately. The specific process is as follows:

[0106] First, it is determined that the frequency of the driver viewing the vehicle display screen is greater than a preset frequency, and then the priority of the display content of the vehicle display screen is determined; then, the display content with a priority greater than the preset priority is enlarged and displayed.

[0107] Among them, the priority of displayed content is usually that driving information and safety warnings are of higher priority, such as navigation information, vehicle speed information, and vehicle status warning information; while entertainment content is of lower priority, such as multimedia details, incoming call and message notifications, and social media notifications.

[0108] Optionally, when it is determined that the driver checks the on-board display screen more frequently than a preset frequency and it is judged that the driver may be distracted, the "sport mode" can be automatically started to highlight driving performance-related content on the vehicle display screen, such as speed, power output and other information.

[0109] It is understandable that after determining that the frequency of the driver checking the vehicle-mounted display screen is greater than the preset frequency, a distraction assessment is performed. In addition to determining that the driver's line of sight may be affected by screen reflections, the driver may also be in a distracted state. Therefore, the priority of the content displayed on the vehicle display screen is adjusted to increase the display frequency or mode of high-priority information, such as placing it in the core area of ​​the screen or highlighting it through high brightness, color contrast, etc., while other priority information is hidden or concentrated in a position where the driver's line of sight is not easily distracted, such as the corners of the screen, to avoid interfering with the driver's attention.

[0110] Figure 3 The schematic diagram shows the process of the control method of the vehicle display screen provided by the present invention. Figure 2 .like Figure 3 As shown, the method comprises the following steps:

[0111] Step 301: Determine the time the driver stares at the vehicle display screen according to the gaze point.

[0112] It can be understood that the eye tracking module captures the driver's eye position in real time, analyzes the direction of his gaze, and records the start time when the driver's line of sight is within the range of the vehicle display screen to obtain the length of time the driver stares at the vehicle display screen.

[0113] Step 302: If the duration is less than the preset duration, the vehicle display screen is controlled to turn off.

[0114] It should be understood that if it is detected that the driver's gaze stays on the vehicle display screen for a time shorter than a set threshold, it is determined that the driver does not need to watch the content on the vehicle display screen. In order to reduce interference to the driver and the use of energy inside the vehicle, the intelligent screen activation / sleep module in the energy consumption control system will automatically control the vehicle display screen to enter a sleep state or reduce the screen brightness.

[0115] It should be noted that in order to ensure that the driver can still obtain key navigation or entertainment information without being disturbed by visual information, even if the in-vehicle display is in sleep mode, the background information can still continue to be played in the form of sound, such as navigation announcements and music. Furthermore, the driver can also choose the type of voice information in the screen sleep mode according to their own habits, such as keeping only navigation instructions, or providing navigation prompts while playing music, to help the driver get a better user experience.

[0116] It is understandable that by obtaining the time the driver is looking at the screen and intelligently reducing the brightness of the screen or putting it into sleep mode, the interference to the driver can be minimized while ensuring that the driver obtains relevant information, and a balance between energy saving and information transmission can be achieved.

[0117] In one feasible method, if the duration is longer than the preset duration, in order to prevent the driver from visual fatigue, the screen needs to be adjusted. The specific adjustment methods include:

[0118] If the duration is greater than or equal to the preset duration, the vehicle display screen will be adjusted to eye protection mode.

[0119] Optionally, if the duration is greater than or equal to the preset duration, and the ambient light sensor in the vehicle obtains that the light conditions inside and outside the vehicle are at a dark level, the vehicle display screen is adjusted to dark mode, that is, the background color of the vehicle display screen is changed to a dark color, and the text or image is changed to a light color, thereby reducing the stimulation of the strong light of the vehicle display screen to the eyes.

[0120] It should be understood that if the eye tracking module monitors the driver's eye activities in real time and continuously pays attention to the flickering frequency, eye movement speed and continuous time of looking at the screen, if the driver looks at the vehicle display screen for a time greater than or equal to the preset time, it is determined that the driver may need to view the screen content for a long time, and the vision protection module is activated to dynamically adjust the brightness, color temperature and blue light level of the screen display to protect eyesight.

[0121] It should be noted that in addition to monitoring the driver's gaze point, the gaze points of other passengers in the vehicle can also be monitored, and different preset durations for looking at the vehicle display screen can be set for minors and adults. For example, if a child stares at the screen for more than 15 minutes or an adult stares at the screen for more than 30 minutes, the eye protection mode is triggered. In this way, the age of passengers in different positions can be obtained first to determine the maximum time the passenger stares at the screen, and the corresponding passenger's screen staring duration can be captured in real time to further determine whether to turn on the eye protection mode.

[0122] Furthermore, if the vehicle-mounted display screen turns on the eye protection mode, the length of time the passenger at that position stares at the screen is re-acquired. If the length of time is still greater than or equal to the preset length of time, the priority of the screen display content is first determined. If the priority is high, such as continuously paying attention to road navigation information, the eye protection mode is continuously turned on; if the priority is not high, such as playing cartoons and other entertainment information, the screen is automatically turned off or locked for a period of time (for example, 30 minutes) to encourage the occupant to rest.

[0123] For example, the high-precision camera of the eye tracking module captures the facial information and eye positions of the driver and the passenger in the front passenger seat, and obtains that the driver is 30 years old and stares at the central control display for 10 minutes, and the passenger in the front passenger seat is 15 years old and stares at the front passenger display for 31 minutes. First, the screen brightness of the central control display is reduced to save energy, and then the screen brightness of the front passenger display is reduced, the color temperature is adjusted to warm tones, and the blue light output ratio is reduced to turn on the eye protection mode.

[0124] Optionally, in addition to adjusting the display status of the vehicle display, it is also necessary to provide prompt information to the driver, including:

[0125] Displays a prompt message.

[0126] Among them, the prompt information is used to remind the driver to protect his eyesight.

[0127] Optionally, in addition to displaying prompt information in text form on the vehicle display screen, passengers can also be reminded to take adequate rest through voice, or the tone and rhythm of background music can be changed to attract the attention of passengers or drivers, prompting them to temporarily shift their gaze and relieve visual fatigue.

[0128] It is understandable that when it is detected that the time a passenger or driver in different positions looks at the screen is longer than the preset time, in addition to turning on the eye protection mode, a prompt message will be displayed. For example, a vision protection prompt will pop up, suggesting that the occupant take a short break or do eye exercises. For minors, the prompt may be presented in an animated form to increase its appeal.

[0129] The control method of the vehicle-mounted display screen provided in the embodiment of the present invention obtains the screen staring time of passengers or drivers in different positions and determines whether the screen staring time exceeds the corresponding preset time, so as to specifically perform screen sleep or turn on the eye protection mode, thereby reducing the vehicle's energy consumption while ensuring the driver obtains information, reducing interference to the driver and protecting the passengers' eyesight, enhancing the safety and comfort of riding, and realizing the intelligent and personalized information display, providing passengers with a higher quality riding experience.

[0130] Figure 4 The schematic diagram of the structure of the control device of the vehicle display screen provided by the present invention is shown. Figure 4 As shown, the control device 40 of the vehicle-mounted display screen includes: a first determination module 401 , a second determination module 402 , a third determination module 403 and an adjustment module 404 .

[0131] A first determination module 401 is used to determine the driver's gaze point based on the driver's eye activity data, where the eye activity data includes the driver's target eye position and sight direction;

[0132] A second determination module 402 is used to determine the frequency of the driver viewing the vehicle display screen according to the gaze point;

[0133] The third determination module 403 is used to determine the target angle according to the target eye position if the frequency is greater than the preset frequency; compared with the current angle of the vehicle display screen, the reflection effect of the vehicle display screen on the driver is reduced when the vehicle display screen is at the target angle.

[0134] The adjustment module 404 is used to adjust the vehicle-mounted display screen to a target angle.

[0135] In an optional manner, the third determining module 403 is specifically configured to:

[0136] Determine the target angle based on the target eye position and the brightness outside the target vehicle.

[0137] In an optional manner, the third determining module 403 is specifically configured to:

[0138] Determine the target reflectivity of the vehicle display screen according to the target eyeball position and the target exterior brightness of the vehicle;

[0139] The target angle is determined according to the target reflectivity and the mapping relationship, wherein the mapping relationship includes the corresponding relationship between the reflectivity and the angle.

[0140] In an optional manner, the third determining module 403 is further configured to:

[0141] Determine the target display screen brightness according to the target eyeball position and the target vehicle exterior brightness;

[0142] Adjust the vehicle display to the target display brightness.

[0143] In an optional manner, the control device of the vehicle-mounted display screen further includes a processing module, which is used to:

[0144] Determine the length of time the driver stares at the in-vehicle display based on the gaze point;

[0145] If the duration is less than the preset duration, the vehicle display screen will be turned off.

[0146] In an optional manner, the third determining module 403 is further configured to:

[0147] Determining that the frequency of the driver viewing the vehicle display screen is greater than a preset frequency, then determining the priority of the content displayed on the vehicle display screen;

[0148] The display content with a priority greater than a preset priority is enlarged and displayed.

[0149] In an optional manner, the adjustment module 404 is further configured to:

[0150] If the duration is greater than or equal to the preset duration, the vehicle display screen will be adjusted to eye protection mode.

[0151] In an optional manner, the processing module is further configured to:

[0152] Display prompt information to remind the driver to protect his eyesight.

[0153] From the above, it can be seen that the control device 50 of the vehicle-mounted display screen provided in the embodiment of the present invention not only reduces the impact of screen reflection on the driver's line of sight, ensuring that the information on the screen can be clearly read by the driver under various lighting conditions, but also further helps the driver to keep his line of sight focused, reduces visual fatigue, and improves comfort and safety during long-term driving. On this basis, the energy efficiency of the vehicle can be improved by intelligently adjusting the screen brightness and turning on the eye protection mode, providing passengers with a safer, more comfortable and personalized riding environment, which is of great significance for protecting children's eyesight and enhancing driving safety.
