Technical Field
[0001] This application relates to the field of vehicles, and more specifically, to methods, apparatus and vehicles for switching image quality in the field of vehicles. Background Technology
[0002] As automotive technology continues to advance and people's living standards improve, the target audience for vehicles is expanding. However, this also brings with it a growing number of vehicle-related problems, including image quality issues when watching videos on in-car screens. These problems can negatively impact the user experience. Summary of the Invention
[0003] This application provides a method, apparatus, and vehicle for switching image quality, which can improve the user experience of vehicle users.
[0004] In a first aspect, a method for switching image quality is provided, the method comprising: when the image quality mode of a first vehicle screen is switched to a first image quality mode, obtaining the current display content of a second vehicle screen, wherein the image quality mode of the second vehicle screen has a cooperative relationship with the image quality mode of the first vehicle screen; and when the current display content is the preset display content, maintaining the image quality mode of the second vehicle screen, wherein the preset display content is used to indicate that the first image quality mode is not applicable to the vehicle user corresponding to the second vehicle screen.
[0005] In the above technical solution, when the image quality mode of the first in-vehicle screen switches to the first image quality mode, the current display content on the second in-vehicle screen is analyzed. When the current display content on the second in-vehicle screen is preset display content, the image quality mode of the second in-vehicle screen is controlled to remain the original image quality mode, that is, the current image quality mode is maintained. The image quality mode of the second in-vehicle screen and the image quality mode of the first in-vehicle screen have a cooperative relationship. This avoids situations where the image quality is switched while the vehicle user is looking at the second in-vehicle screen, resulting in the switched image quality mode being unsuitable for the vehicle user. When the vehicle user is the driver, this can distract the driver's attention and interfere with the driver's vision, thereby affecting driving safety and even causing traffic accidents. Therefore, this method can control whether the image quality modes of the first and second in-vehicle screens should be cooperative based on the actual driving scenario, rather than controlling the image quality mode of the second in-vehicle screen to remain consistent with the image quality mode of the first in-vehicle screen in all scenarios. This improves the user experience.
[0006] In conjunction with the first aspect, in some possible implementations, the first image quality mode is a standard image quality mode, and the method for determining that the image quality mode of the first vehicle screen is switched to the first image quality mode includes: in response to a playback instruction for a first video of a target type on the first vehicle screen, determining that the image quality mode of the first vehicle screen is switched to the standard image quality mode, wherein the target type is the type of video played in the standard image quality mode.
[0007] In the above technical solution, when a first video of the target type is triggered on the first in-vehicle screen, the method can switch the image quality mode of the first in-vehicle screen to a standard image quality mode and play the first video in this standard image quality mode. This can meet the vehicle user's playback needs for the first video of the target type on the first in-vehicle screen, and can also play the first video in the image quality mode corresponding to the first video, so that the first video has a better display effect.
[0008] In conjunction with the first aspect, in some possible implementations, the method further includes: when the currently displayed content is not the preset display content, switching the image quality mode of the second vehicle screen to the first image quality mode, and displaying a first prompt message and a target control in the first display area of the second vehicle screen, wherein the first prompt message is used to indicate that the image quality mode of the second vehicle screen has been coordinated with the first vehicle screen, and the target control is used to trigger the image quality mode of the second vehicle screen to switch back from the first image quality mode to the original image quality mode.
[0009] In the above technical solution, when the second vehicle screen does not display preset display information, the vehicle directly switches the image quality mode of the second vehicle screen to the first image quality mode. This is because switching the image quality of the second vehicle screen when it does not display preset display information will not affect the vehicle user and can also ensure that the image quality of the second vehicle screen is consistent with that of the first vehicle screen. Furthermore, displaying a first prompt message in the first display area of the second vehicle screen can remind the vehicle user of the reason for the image quality switch. In addition, displaying a target control in the first display area can prevent the vehicle user from requesting a restoration of the image quality mode if they are dissatisfied with it.
[0010] In combination with the first aspect and the above implementation methods, in some possible implementation methods, after switching the image quality mode of the second vehicle screen to the first image quality mode, the method further includes: determining whether the display optimization mode of the second vehicle screen is in an on state, the display optimization mode being used to optimize the screen parameters of the second vehicle screen; and controlling the display optimization mode to be in a off state when the display optimization mode is in an on state.
[0011] In the above technical solution, after switching the image quality mode of the second vehicle screen to the first image quality mode, the method controls the display optimization mode of the second vehicle screen to be turned off. This allows the display optimization mode to be turned off when there is no need for its use, thereby reducing the vehicle's energy consumption.
[0012] In combination with the first aspect and the above implementation methods, in some possible implementation methods, when the currently displayed content is the preset display content, the image quality mode of the second vehicle screen is maintained, including: when the currently displayed content is the preset display content, displaying a second prompt message on the second display area of the second vehicle screen, the second prompt message being used to indicate that the second vehicle screen is displaying the preset display content and that switching the image quality mode is not recommended in order not to affect the vehicle user's use of the second vehicle screen, and to confirm whether to switch the image quality mode of the second vehicle screen, the area of the second display area being larger than the area of the first display area of the second vehicle screen; if the second prompt message is not confirmed, the image quality mode of the second vehicle screen is maintained.
[0013] In the above technical solution, when the current display content of the second vehicle screen is preset display information, the vehicle displays a second prompt message in the second display area of the second vehicle screen. This second prompt message indicates that the second vehicle screen is displaying the preset display content and that switching the image quality mode is not recommended to avoid affecting the vehicle user's use of the second vehicle screen. This allows the vehicle user to understand why the second vehicle screen is not switching image quality. Furthermore, the second prompt message also confirms whether to switch the image quality of the second vehicle screen. This provides the vehicle user with the right to choose whether to switch the image quality of the second vehicle screen based on their own needs. Therefore, this method, to a certain extent, ensures that the vehicle user's use of the second vehicle screen is not affected, and also meets the vehicle user's need to independently switch the image quality mode of the vehicle screen.
[0014] In combination with the first aspect and the above implementation methods, in some possible implementation methods, the second vehicle screen is a central control screen, and the method further includes: when the second prompt information is confirmed, obtaining the driving environment parameters of the vehicle; determining the switching duration based on the driving environment parameters and the screen brightness of the second vehicle screen, the switching duration being the duration required to switch the image quality mode of the second vehicle screen from the original image quality mode to the first image quality mode; and switching the image quality mode of the second vehicle screen to the first image quality mode based on the switching duration.
[0015] In the above technical solution, when the driver needs to switch the image quality mode of the second in-vehicle screen, the vehicle determines the switching duration based on the vehicle's driving environment parameters and the screen brightness of the second in-vehicle screen. This is because the driver needs to obtain safety information from the second in-vehicle screen while driving; therefore, the influence of the screen brightness is considered in determining the switching duration. Furthermore, the driver has become accustomed to the ambient brightness after prolonged exposure. Different switching durations have varying impacts on the driver's attention and vision during the switching of the second in-vehicle screen's image quality mode. To make the image quality switching effect easier and faster for the driver to adapt to, the switching duration is also related to the ambient brightness. Therefore, in this method, the vehicle switches the image quality mode of the second in-vehicle screen to the first image quality mode based on the switching duration, avoiding impact on the driver's attention and vision, ensuring the driver can clearly view the safety information on the second in-vehicle screen, and improving vehicle driving safety.
[0016] In conjunction with the first aspect and the above-described implementation methods, in some possible implementation methods, the driving environment parameters include the congestion level of the road segment in which the vehicle is driving and the ambient brightness inside the vehicle. Based on the driving environment parameters and the screen brightness of the second in-vehicle screen, the switching duration is determined, including: when the congestion level is less than a first preset level, determining a first target duration as the switching duration, the first target duration being the shortest duration for the vehicle to switch image quality modes; when the congestion level is greater than or equal to the first preset level, determining the deviation of the screen brightness from the ambient brightness, and determining the adjustment duration by multiplying the second target duration by the deviation duration, the second target duration being related to the historical duration of the driver's gaze at the second in-vehicle screen; when the screen brightness is greater than the ambient brightness, determining the switching duration by the sum of the second target duration and the adjustment duration; when the screen brightness is less than or equal to the ambient brightness, determining the switching duration by the difference between the second target duration and the adjustment duration.
[0017] In the aforementioned technical solution, when traffic congestion is low, vehicle movement is relatively smooth and at a relatively high speed, with the driver's attention primarily focused on the road. Therefore, faster image quality switching is permissible, allowing for shorter switching durations. When traffic congestion is high, the driver needs to frequently operate the vehicle to view safety information (traffic information, navigation instructions, or entertainment content) on the second in-vehicle screen. Therefore, longer image quality switching is permissible, allowing for longer switching durations. Specifically, drivers are more adaptable to ambient brightness. In low-light conditions, the slower switching speed (longer switching duration) in this method allows the driver's eyes sufficient time to adapt to changes in image quality. For example, when switching from one brightness and color mode to another, a slow switch allows the driver's visual system to transition smoothly without sudden visual shock, thus facilitating accurate reading of information on the central control screen after the switch. Conversely, in high-light conditions, this method employs a faster switching speed (shorter switching duration) due to better driver visibility. This reduces the processor's workload.
[0018] In conjunction with the first aspect and the above-described implementation methods, in some possible implementation methods, the method for determining the second target duration includes: if a first trip corresponding to the driving segment exists in the vehicle's historical travel history, determining the first average duration for which the driver repeatedly looks at the second in-vehicle screen during the first trip, and determining the first average duration as the second target duration; or, if the first trip does not exist in the historical travel history but a second trip corresponding to other driving segments exists, determining the second average duration for which the driver repeatedly looks at the second in-vehicle screen during the second trip, and determining the second average duration as the second target duration; or, if neither the first trip nor the second trip exists in the historical travel history, obtaining the third average duration for which other drivers repeatedly look at the second in-vehicle screen when other vehicles are driving on the driving segment, and determining the third average duration as the second target duration.
[0019] In the above technical solution, the second target duration is determined by the driver's driving habits (first average duration of looking at the second in-vehicle screen) during the driver's historical journey (first journey) on the driving segment. This takes into account the driver's specific preferences when using the second in-vehicle screen, and the setting based on individual driving habits can also improve the driver's driving experience. When the driver has not driven on the driving segment in the historical period, the method determines the second target duration by the driver's driving habits when driving on other segments (second average duration of looking at the second in-vehicle screen). Compared to the first average duration, the accuracy of the second average duration is lower because the road conditions on the driving segment may be complex, while the road conditions on other segments may be better. However, this method can avoid the situation where the second target duration cannot be determined when the first journey does not exist. In addition, when the driver does not have a historical journey, the second target duration is determined by the driving habits of other drivers on the driving segment (third average duration of looking at the second in-vehicle screen). Although this method does not consider the driver's driving habits, it can still avoid the situation where the second target duration cannot be determined when the first journey does not exist.
[0020] Secondly, an apparatus for switching image quality is provided, the apparatus comprising: an acquisition module, configured to acquire the current display content of a second vehicle screen when the image quality mode of a first vehicle screen is switched to a first image quality mode, wherein the image quality mode of the second vehicle screen has a cooperative relationship with the image quality mode of the first vehicle screen; and a switching module, configured to maintain the image quality mode of the second vehicle screen when the current display content is the preset display content, wherein the preset display content is used to indicate that the first image quality mode is not applicable to the vehicle user corresponding to the second vehicle screen.
[0021] In conjunction with the second aspect, in some possible implementations, the device further includes: a determining module, configured to determine, in response to a playback instruction for a first video of a target type on the first vehicle screen, that the image quality mode of the first vehicle screen is switched to a standard image quality mode, wherein the target type is a video type played in the standard image quality mode.
[0022] In conjunction with the second aspect and the above implementation methods, in some possible implementation methods, the device further includes: a display module, configured to switch the image quality mode of the second vehicle screen to the first image quality mode when the currently displayed content is not the preset display content, and to display a first prompt message and a target control in a first display area on the second vehicle screen, wherein the first prompt message is used to indicate that the image quality mode of the second vehicle screen has been coordinated with the first vehicle screen, and the target control is used to trigger the image quality mode of the second vehicle screen to switch back from the first image quality mode to the original image quality mode.
[0023] In conjunction with the second aspect and the above implementation methods, in some possible implementation methods, after the image quality mode of the second vehicle screen is switched to the first image quality mode, the determining module is further used to determine whether the display optimization mode of the second vehicle screen is in the open state, the display optimization mode is used to optimize the screen parameters of the second vehicle screen; the switching module is further used to control the display optimization mode to be in the closed state when the display optimization mode is in the open state.
[0024] In conjunction with the second aspect and the above implementation methods, in some possible implementation methods, the display module is specifically used to display a second prompt message in the second display area of the second vehicle screen when the currently displayed content is the preset display content. The second prompt message is used to prompt that the second vehicle screen is displaying the preset display content and that it is not recommended to switch the image quality mode in order not to affect the vehicle user's use of the second vehicle screen, and to confirm whether to switch the image quality mode of the second vehicle screen. The area of the second display area is larger than the area of the first display area of the second vehicle screen. The device further includes: a control module, used to maintain the image quality mode of the second vehicle screen when the second prompt message is not confirmed.
[0025] In conjunction with the second aspect and the above implementation methods, in some possible implementation methods, the second vehicle screen is a central control screen, and the acquisition module is further used to acquire the driving environment parameters of the vehicle when the second prompt information is confirmed; the device further includes: a determining module, used to determine the switching duration based on the driving environment parameters and the screen brightness of the second vehicle screen, the switching duration being the duration required to switch the image quality mode of the second vehicle screen from the original image quality mode to the first image quality mode; the switching module is specifically used to switch the image quality mode of the second vehicle screen to the first image quality mode based on the switching duration.
[0026] In conjunction with the second aspect and the above implementation methods, in some possible implementation methods, the driving environment parameters include the congestion level of the road segment in which the vehicle is driving and the ambient brightness inside the vehicle. The determining module is specifically used for: when the congestion level is less than a first preset level, determining a first target duration as the switching duration, wherein the first target duration is the shortest duration for the vehicle to switch the image quality mode; when the congestion level is greater than or equal to the first preset level, determining the deviation of the screen brightness relative to the ambient brightness, and determining the product between the second target duration and the deviation as the adjustment duration, wherein the second target duration is related to the historical duration for which the driver looks at the second in-vehicle screen; when the screen brightness is greater than the ambient brightness, determining the sum of the second target duration and the adjustment duration as the switching duration; and when the screen brightness is less than or equal to the ambient brightness, determining the difference between the second target duration and the adjustment duration as the switching duration.
[0027] In conjunction with the second aspect and the above implementation methods, in some possible implementation methods, the determining module is further configured to: if a first trip corresponding to the driving segment exists in the vehicle's historical travel history, determine the first average duration for which the driver repeatedly looks at the second in-vehicle screen during the first trip, and determine the first average duration as the second target duration; or, if the first trip does not exist in the historical travel history but a second trip corresponding to other driving segments exists, determine the second average duration for which the driver repeatedly looks at the second in-vehicle screen during the second trip, and determine the second average duration as the second target duration; or, if neither the first trip nor the second trip exists in the historical travel history, obtain the third average duration for which other drivers repeatedly look at the second in-vehicle screen when other vehicles are driving on the driving segment, and determine the third average duration as the second target duration.
[0028] Thirdly, a vehicle is provided, including a memory and a processor. The memory is used to store executable program code, and the processor is used to call and run the executable program code from the memory, causing the vehicle to perform the methods described in the first aspect or any possible implementation thereof.
[0029] Fourthly, a computer-readable storage medium is provided that stores executable program code, which, when run on a computer, causes the computer to perform the methods described in the first aspect or any possible implementation thereof. Attached Figure Description

[0034] Figure 5 This is a schematic diagram of the structure of a vehicle provided in an embodiment of this application. Detailed Implementation
[0035] The technical solutions in this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.
[0036] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting 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 that feature.
[0037] Figure 1 This is a schematic diagram of a scenario where a vehicle is used, as provided in an embodiment of this application.
[0038] For example, such as Figure 1 As shown, the front screens in vehicle A include a central control screen and a passenger-side screen. The central control screen is typically installed in the central area of the vehicle's center console, between the driver's and passenger's seats, making it convenient for both the driver and passenger to operate and view. The passenger-side screen is usually installed on the dashboard in front of the passenger seat, allowing the passenger to operate it easily without obstructing the driver's view or operation. The central control screen and the passenger-side screen are located adjacent to each other.
[0039] To ensure consistent image quality between the central control screen and the passenger-side screen, the image quality of the passenger-side screen is typically coordinated with that of the central control screen, meaning they are updated or switched synchronously. However, this presents some problems. In some embodiments, regardless of the information displayed on the central control screen, the image quality switches along with that of the passenger-side screen. This can cause the driver, who is looking directly at the central control screen, to be unable to adapt to the image quality changes in a timely manner, leading to eye discomfort. For example, the driver may experience temporary blurred vision, slight stinging, or, in extreme cases, even dizziness.
[0040] The following description will use the aforementioned central control screen and passenger-side screen as examples. However, it should be understood that this application is not limited to this. In fact, this application applies to any two or more screens whose image quality can be coordinated with each other. For example, for rear screens including a left rear ceiling screen and a right rear ceiling screen, when one screen is used by a child and the other by an adult, the child and adult have different needs, at least in terms of eye protection and color. If an adult adjusts the screen's image quality according to their own needs, that image quality may not be suitable for a child. In this case, the image quality of the screen being used by the child should obviously not be automatically adjusted synchronously.
[0041] To address the aforementioned issues, this application provides a method for switching image quality to improve the user experience for vehicle users. The specific implementation steps are as follows: Figure 2 As shown.
[0042] Figure 2 This is a schematic flowchart illustrating a method for switching image quality provided in an embodiment of this application.
[0043] It should be understood that the method for switching image quality provided in this application embodiment can be applied to, for example, Figure 1 The vehicle shown is an example, vehicle A. Specifically, the method for switching image quality can be applied to a target controller in the vehicle. The target controller is either a vehicle controller or a body domain controller. The body domain controller is used to control various vehicle components within the vehicle. In the image quality switching method of this application, the vehicle component is an in-vehicle screen, specifically a first in-vehicle screen and a second in-vehicle screen.
[0044] For example, such as Figure 2 As shown, the method 200 includes steps 201 and 202.
[0045] Step 201: When the image quality mode of the first vehicle screen is switched to the first image quality mode, the vehicle obtains the current display content of the second vehicle screen. The image quality mode of the second vehicle screen has a cooperative relationship with the image quality mode of the first vehicle screen.
[0046] It should be understood that the phrase "the image quality mode of the second vehicle screen has a cooperative relationship with the image quality mode of the first vehicle screen" in step 201 above is used to indicate that the image quality mode of the second vehicle screen and the first vehicle screen can be kept consistent. Under normal circumstances, the position of the second vehicle screen is adjacent to the position of the first vehicle screen.
[0047] It should also be understood that the "image quality mode" in step 201 above refers to the different processing methods and parameter settings used by the in-vehicle screen when displaying images to optimize the quality of the displayed images. These image quality modes include Standard Image Quality Mode, Vivid Image Quality Mode, Soft Image Quality Mode, Natural Image Quality Mode, and Game Image Quality Mode. Specifically, the Standard Image Quality Mode provides a balanced image quality and performance; the Vivid Image Quality Mode enhances the color saturation and vibrancy of the image; the Soft Image Quality Mode provides a softer and more delicate image effect while reducing image sharpening and contrast; the Natural Image Quality Mode provides a more natural light and color representation; and the Game Image Quality Mode provides faster response times and lower latency.
[0048] In some embodiments, the process of the vehicle obtaining the current display content of the second in-vehicle screen in step 201 includes: the vehicle obtaining the current display content of the second in-vehicle screen from a target application built into the vehicle's multimedia system.
[0049] In one possible implementation, the first image quality mode is a standard image quality mode. The method for determining the image quality mode of the first vehicle screen to switch to the first image quality mode in step 202 includes: the vehicle responding to a playback instruction for a first video of a target type on the first vehicle screen, determining that the image quality mode of the first vehicle screen is switched to the standard image quality mode, where the target type is the type of video played in the standard image quality mode.
[0050] It should be understood that "the target type is the video type played in standard quality mode" in the above scheme can be interpreted as: the target type of video displays best when played in standard quality mode. In some embodiments, the target type is a High Dynamic Range (HDR) video type. It should be understood that the target type of video (e.g., HDR video) is dependent on the standard quality mode and mutually exclusive with other quality modes (vivid quality mode, soft quality mode, natural quality mode, and game quality mode).
[0051] In some embodiments, the passenger in the vehicle triggers the playback command via voice; or, the passenger triggers the playback command by clicking on a first video of the target type; or, the passenger triggers the playback command by a selection gesture, wherein the selection gesture is an open palm gesture.
[0052] Figure 3 This is a schematic diagram of an image quality function in a vehicle provided in an embodiment of this application.
[0053] For example, such as Figure 3 As shown, the image quality functions in the vehicle serve the displayed images (e.g., videos) on the video playback components of the in-vehicle screens. These in-vehicle screens include a first in-vehicle screen and a second in-vehicle screen. The types of videos that can be played on these screens include HDR video and other video types, including Standard Dynamic Range (SDR) video and High Definition Blu-ray video. The vehicle can control the image quality mode, eye protection mode, and color correction mode of the in-vehicle screens via an image quality control component. The image quality modes include a standard image quality mode and other image quality modes, including vivid image quality mode, soft image quality mode, natural image quality mode, and game image quality mode.
[0054] Step 202: When the currently displayed content is the preset display content, the vehicle maintains the image quality mode of the second in-vehicle screen. The preset display content is used to indicate that the first image quality mode is not applicable to the vehicle user corresponding to the second in-vehicle screen.
[0055] It should be understood that "maintaining the image quality mode of the second in-vehicle screen" in step 202 above means not changing the original image quality mode of the second in-vehicle screen, and controlling the image quality mode of the second in-vehicle screen to remain at the original image quality mode. In some embodiments, the first in-vehicle screen is a passenger-side screen, and the second in-vehicle screen is a central control screen. In some embodiments, the preset display content includes navigation content, reversing image, tire status, and a 360-degree view of the vehicle while it is moving forward. The driver needs to obtain safety information from the second in-vehicle screen to assist in driving. Therefore, arbitrarily switching the image quality mode of the second in-vehicle screen will distract the driver and interfere with the driver's vision, thereby affecting driving safety. Therefore, the image quality mode of the second in-vehicle screen cannot be arbitrarily switched.
[0056] It should also be understood that the phrase "preset display content is used to indicate that the first image quality mode is not applicable to the vehicle user corresponding to the second in-vehicle screen" in step 202 above means that if the image quality mode of the second in-vehicle screen is switched to the first image quality mode, it will affect the vehicle user's current use of the second in-vehicle screen. In some embodiments, the first in-vehicle screen is the rear left ceiling screen in the vehicle, and the second in-vehicle screen is the rear screen of the rear right ceiling screen in the vehicle. The first in-vehicle screen is used by children, and the second in-vehicle screen is used by adults. Children and adults have different needs in terms of eye protection and color. If an adult switches the image quality mode of the second in-vehicle screen to the first image quality mode according to their own needs, switching the image quality mode of the first in-vehicle screen to the first image quality mode may not be suitable for children.
[0057] In one possible implementation, step 202, where the vehicle maintains the image quality mode of the second vehicle screen when the currently displayed content is the preset display content, includes: when the currently displayed content is the preset display content, the vehicle displays a second prompt message in the second display area of the second vehicle screen. The second prompt message is used to indicate that the second vehicle screen is displaying the preset display content and that switching the image quality mode is not recommended to avoid affecting the user's use of the second vehicle screen, and to confirm whether to switch the image quality mode of the second vehicle screen. The area of the second display area is larger than the area of the first display area of the second vehicle screen. If the second prompt message is not confirmed, the vehicle maintains the image quality mode of the second vehicle screen.
[0058] It should be understood that the phrase "the area of the second display area is larger than the area of the first display area on the second vehicle screen" in the above scheme can be regarded as the second display area being more eye-catching than the first display area. Compared with the first display area, the second display area can attract the driver's attention first.
[0059] It should also be understood that the "second prompt message" in the above scheme has two functions: First, it prompts that the second in-vehicle screen is displaying the preset display content and that it is not recommended to switch the image quality mode in order not to affect the vehicle user's use of the second in-vehicle screen; Second, it gives the vehicle user the right to choose whether to switch the image quality of the second in-vehicle screen.
[0060] In the above technical solution, when the current displayed content of the second vehicle screen is the preset display content, the vehicle displays a second prompt message in the second display area of the second vehicle screen. This second prompt message indicates that the second vehicle screen is displaying the preset display content and that switching the image quality mode is not recommended to avoid affecting the vehicle user's use of the second vehicle screen. This allows the vehicle user to understand why the second vehicle screen is not switching image quality. Furthermore, the second prompt message also confirms whether to switch the image quality of the second vehicle screen. This provides the vehicle user with the right to choose whether to switch the image quality of the second vehicle screen based on their own needs. Therefore, this method, to a certain extent, can both avoid affecting the vehicle user's use of the second vehicle screen and meet the vehicle user's need to independently switch the image quality mode of the vehicle screen.
[0061] In some embodiments, the vehicle displays a second prompt message in a second display area on the second in-vehicle screen, including: the vehicle displays the second prompt message in the upper-middle area of the second in-vehicle screen.
[0062] In some embodiments, the vehicle displays a second prompt message in a second display area on the second vehicle screen, including: the vehicle displays the second prompt message in a pop-up window in the second display area on the second vehicle screen.
[0063] In one possible implementation, the second in-vehicle screen is a central control screen. The method 200 further includes: when the second prompt information is confirmed, the vehicle obtains the vehicle's driving environment parameters; the vehicle determines a switching duration based on the driving environment parameters and the screen brightness of the second in-vehicle screen, the switching duration being the time required to switch the image quality mode of the second in-vehicle screen from the original image quality mode to the first image quality mode; the vehicle switches the image quality mode of the second in-vehicle screen to the first image quality mode based on the switching duration.
[0064] It should be understood that in the above scheme, after the second prompt message is confirmed, it indicates that the driver needs to switch the image quality mode of the second vehicle screen. In order to reduce the impact on the driver's attention and vision when switching the image quality of the second vehicle screen, the vehicle determines the switching duration based on the vehicle's driving environment parameters and the screen brightness of the second vehicle screen, and switches the image quality of the second vehicle screen according to the switching duration.
[0065] It should also be understood that the "driving environment parameters" in the above scheme refer to environmental parameters that affect the driver's visual behavior and driving experience during vehicle driving. These driving environment parameters include at least one of the following: the degree of congestion, the degree of bumpiness and the type of road segment in which the vehicle is driving; the ambient brightness inside the vehicle; and the weather conditions and lighting conditions outside the vehicle.
[0066] In the above technical solution, when the driver needs to switch the image quality mode of the second in-vehicle screen, the vehicle determines the switching duration based on the vehicle's driving environment parameters and the screen brightness of the second in-vehicle screen. This is because the driver needs to obtain safety information from the second in-vehicle screen while driving; therefore, the influence of the screen brightness is considered in determining the switching duration. Furthermore, the driver has become accustomed to the ambient brightness after prolonged exposure. Different switching durations have varying impacts on the driver's attention and vision during the switching of the second in-vehicle screen's image quality mode. To make the image quality switching effect easier and faster for the driver to adapt to, the switching duration is also related to the ambient brightness. Therefore, in this method, the vehicle switches the image quality mode of the second in-vehicle screen to the first image quality mode based on the switching duration, avoiding impact on the driver's attention and vision, ensuring the driver can clearly view the safety information on the second in-vehicle screen, and improving vehicle driving safety.
[0067] The process of "determining the switching duration" is explained in the following sections, categorized by scenario.
[0068] Scenario 1: Driving environment parameters include the level of traffic congestion on the road and the ambient light inside the vehicle.
[0069] In one possible implementation, the driving environment parameters include the congestion level of the road segment the vehicle is traveling on and the ambient brightness inside the vehicle. Based on these driving environment parameters and the screen brightness of the second in-vehicle screen, the vehicle determines the switching duration, including: if the congestion level is less than a first preset level, the vehicle determines a first target duration as the switching duration, where the first target duration is the shortest duration for the vehicle to switch image quality modes; if the congestion level is greater than or equal to the first preset level, the vehicle determines the deviation of the screen brightness from the ambient brightness and determines the adjustment duration by multiplying the second target duration by the deviation, where the second target duration is related to the historical duration the driver has viewed the second in-vehicle screen; if the screen brightness is greater than the ambient brightness, the vehicle determines the switching duration by summing the second target duration and the adjustment duration; if the screen brightness is less than or equal to the ambient brightness, the vehicle determines the switching duration by the difference between the second target duration and the adjustment duration.
[0070] It should be understood that, in the above scheme, "the degree of congestion of the road segment" refers to the degree to which the vehicle's speed and traffic capacity are restricted on the road segment. Here, traffic capacity refers to the number of vehicles passing through the road segment per unit time, which is one hour. "Ambient brightness inside the vehicle" refers to the ambient brightness inside the cabin. "First preset level" refers to the degree to which the vehicle's speed on the road segment exceeds a preset speed and traffic capacity exceeds a preset number of vehicles. In some embodiments, the preset speed is 60 km / h, and the preset number of vehicles is 1000 vehicles / hour.
[0071] It should also be understood that the "second target duration" in the above plan is longer than the "first target duration".
[0072] In the aforementioned technical solution, when traffic congestion is low, vehicle movement is relatively smooth and at a relatively high speed, with the driver's attention primarily focused on the road. Therefore, faster image quality switching is permissible, allowing for shorter switching durations. When traffic congestion is high, the driver needs to frequently operate the vehicle to view safety information (traffic information, navigation instructions, or entertainment content) on the second in-vehicle screen. Therefore, longer image quality switching is permissible, allowing for longer switching durations. Specifically, drivers are more adaptable to ambient brightness. In low-light conditions, the slower switching speed (longer switching duration) in this method allows the driver's eyes sufficient time to adapt to changes in image quality. For example, when switching from one brightness and color mode to another, a slow switch allows the driver's visual system to transition smoothly without sudden visual shock, thus facilitating accurate reading of information on the central control screen after the switch. Conversely, in high-light conditions, this method employs a faster switching speed (shorter switching duration) due to better driver visibility. This reduces the processor's workload.
[0073] In some embodiments, the method for determining the congestion level of the road segment includes: a vehicle acquiring its actual driving speed and the actual number of vehicles passing through the road segment per unit time; the vehicle determining the ratio between the actual driving speed and the free-flow speed as a speed ratio, and the ratio between the actual number of vehicles and the theoretical number of vehicles as a flow ratio, wherein the free-flow speed is the normal driving speed of the road segment under congestion-free conditions, and the theoretical number of vehicles is the maximum number of vehicles that can pass through the road segment per unit time under ideal conditions; and the vehicle determining the congestion level of the road segment based on the speed ratio and the flow ratio.
[0074] It should be understood that in the above scheme, "speed ratio" represents the ratio between actual driving speed and free-flow speed. The closer the speed ratio is to 1, the closer the actual driving speed is to the free-flow speed, and the lower the congestion level. "Flow ratio" represents the ratio between the actual number of vehicles (actual traffic volume) and the theoretical number of vehicles (ideal normal traffic volume). The closer the flow ratio is to 1, the closer the actual traffic volume of the road segment is to its theoretical traffic volume, and the moderate congestion level; a flow ratio greater than 1 indicates that the actual traffic volume exceeds its theoretical traffic volume, and the high congestion level.
[0075] In some embodiments, the free-flow speed is the speed limit for the road segment.
[0076] In some embodiments, the vehicle determines the congestion level of the travel segment based on the speed ratio and the flow ratio, including: the vehicle determines the congestion level of the travel segment based on the following formula (1);
[0077]
[0078] Among them, C I v represents the congestion level of the road segment, and v represents the actual driving speed. t Let q be the free-flow velocity, and q be the actual number of vehicles. t This represents the number of vehicles that can travel according to this theory.
[0079] It should be understood that the first half of formula (1) This is used to indicate the contribution of the speed ratio. The smaller the speed ratio, the larger the value in the first half, indicating a higher degree of congestion, and the smaller the value in the second half. This indicates the portion of the flow rate that exceeds the theoretical capacity; the larger the value in the latter half, the higher the degree of congestion.
[0080] In some embodiments, the vehicle determines the deviation of the screen brightness relative to the ambient brightness by: the vehicle determining the difference between the screen brightness and the ambient brightness as a brightness deviation; and the vehicle determining the ratio between the brightness deviation and the ambient brightness as the deviation magnitude.
[0081] In one possible implementation, the method for determining the second target duration includes: if a first trip corresponding to the driving segment exists in the vehicle's historical travel history, the vehicle determines a first average duration for which the driver repeatedly looks at the second in-vehicle screen during the first trip, and determines the first average duration as the second target duration; or, if the first trip does not exist in the historical travel history but a second trip corresponding to other driving segments exists, the vehicle determines a second average duration for which the driver repeatedly looks at the second in-vehicle screen during the second trip, and determines the second average duration as the second target duration; or, if neither the first trip nor the second trip exists in the historical travel history, the vehicle obtains a third average duration for which other drivers repeatedly look at the second in-vehicle screen when other vehicles are driving on the driving segment, and determines the third average duration as the second target duration.
[0082] It should be understood that the phrase "the vehicle's historical travel history includes a first trip corresponding to a certain road segment" in the above scheme can be simply understood as the trips taken by the vehicle using that road segment during the historical time period, where the number of these first trips is greater than or equal to 1. During a single trip, for driving safety, the driver needs to repeatedly look at the second in-vehicle screen to obtain safety-related information.
[0083] In the above technical solution, the second target duration is determined by the driver's driving habits (first average duration of looking at the second in-vehicle screen) during the driver's historical journey (first journey) on the driving segment. This takes into account the driver's specific preferences when using the second in-vehicle screen, and the setting based on individual driving habits can also improve the driver's driving experience. When the driver has not driven on the driving segment in the historical period, the method determines the second target duration by the driver's driving habits when driving on other segments (second average duration of looking at the second in-vehicle screen). Compared to the first average duration, the accuracy of the second average duration is lower because the road conditions on the driving segment may be complex, while the road conditions on other segments may be better. However, this method can avoid the situation where the second target duration cannot be determined when the first journey does not exist. In addition, when the driver does not have a historical journey, the second target duration is determined by the driving habits of other drivers on the driving segment (third average duration of looking at the second in-vehicle screen). Although this method does not consider the driver's driving habits, it can still avoid the situation where the second target duration cannot be determined when the first journey does not exist.
[0084] In some embodiments, the method for determining the other driver includes: the vehicle determining the driver's gender, years of driving experience, and age group; the vehicle comparing the gender with sample genders of multiple sample drivers to determine multiple first candidate drivers with the same gender from the multiple sample drivers; the vehicle comparing the years of driving experience with sample driving years of the multiple first candidate drivers to determine multiple second candidate drivers with the same years of driving experience from the multiple first candidate drivers; the vehicle comparing the age group with sample age groups of the multiple second candidate drivers to determine multiple third candidate drivers with the same age group from the multiple second candidate drivers, and identifying the multiple third candidate drivers as the other driver.
[0085] Scenario 2: Driving environment parameters also include the degree of bumpiness of the road section the vehicle is traveling on.
[0086] In some embodiments, the driving environment parameters include the congestion level and bump level of the road segment in which the vehicle is driving, and the ambient brightness inside the vehicle. The vehicle determines the switching duration based on the driving environment parameters and the screen brightness of the second in-vehicle screen, including: when the congestion level is less than a first preset level and the bump level is less than a second preset level, the vehicle determines a first target duration as the switching duration, where the first target duration is the shortest duration for the vehicle to switch image quality modes; when the congestion level is greater than or equal to the first preset level and the bump level is greater than or equal to the second preset level, the vehicle determines the deviation of the screen brightness from the ambient brightness, and determines the product of the second target duration and the deviation as a first adjustment duration, where the second target duration is related to the historical duration of the driver's gaze at the second in-vehicle screen; the vehicle determines the product of the first adjustment duration and a bump factor as a second adjustment duration, where the bump factor is related to the bump level; when the screen brightness is greater than the ambient brightness, the vehicle determines the sum of the second target duration and the second adjustment duration... The switching duration is determined as follows: When the screen brightness is less than or equal to the ambient brightness, the vehicle determines the switching duration as the difference between the second target duration and the second adjustment duration; when the congestion level is less than the first preset level and the bump level is greater than or equal to the second preset level, the vehicle determines whether the screen brightness is greater than the ambient brightness; when the screen brightness is greater than the ambient brightness, the vehicle determines the switching duration as the sum of the first target duration and the second adjustment duration; when the screen brightness is less than or equal to the ambient brightness, the vehicle determines the switching duration as the difference between the first target duration and the second adjustment duration; when the congestion level is greater than or equal to the first preset level and the bump level is less than the second preset level, the vehicle determines whether the screen brightness is greater than the ambient brightness; when the screen brightness is greater than the ambient brightness, the vehicle determines the switching duration as the sum of the second target duration and the first adjustment duration; when the screen brightness is less than or equal to the ambient brightness, the vehicle determines the switching duration as the difference between the second target duration and the first adjustment duration.
[0087] It should be understood that the "bumpiness of the road section in the above scheme" refers to the degree of vibration caused by the unevenness of the road surface during vehicle operation. Furthermore, this bump factor is equal to the sum of a preset value and the bumpiness level, where the preset value is 1.
[0088] In the above technical solution, when the driving environment parameters also include the degree of bumpiness of the road segment the vehicle is traveling on, the method considers the process of determining the switching duration under various conditions. Specifically, when both congestion and bumpiness are low, the vehicle's journey is relatively smooth, the speed is relatively high, and the driver's attention is mainly focused on the road. Therefore, a faster image quality switch is allowed, and a shorter switching duration is determined. When both congestion and bumpiness are high, the driver needs to operate the vehicle more frequently to view safety information (obtain traffic information, navigation instructions, or entertainment content) on the second in-vehicle screen, and the driver adapts to changes in image quality on the second in-vehicle screen more slowly. Therefore, a longer image quality switch is allowed, and a longer switching duration is determined. When congestion is low but bumpiness is high, the driver's attention is mostly focused on the road. Therefore, a slightly longer switching duration is allowed. And when congestion is high but bumpiness is low, the driver's attention is mostly focused on the second in-vehicle screen. Therefore, a longer switching duration is allowed.
[0089] In some embodiments, the method for determining the bumpiness of the driving segment includes: the vehicle acquiring multiple longitudinal accelerations and multiple wheel rotation speeds at multiple moments during a preset time period; the vehicle determining a first standard deviation of the multiple longitudinal accelerations and a second standard deviation of the multiple rotation speeds; the vehicle performing a weighted summation of the first standard deviation and the second standard deviation based on a first weight and a second weight to obtain the bumpiness of the driving segment, wherein the first weight is used to indicate the contribution of longitudinal acceleration in determining the bumpiness, and the second weight is used to indicate the contribution of wheel rotation speed in determining the bumpiness.
[0090] It should be understood that in the above scheme, each moment corresponds to a longitudinal acceleration and a rotational speed. This rotational speed is either the rotational speed of a single wheel at that moment or the average rotational speed of multiple wheels at that moment.
[0091] In one possible implementation, the method 200 further includes: when the currently displayed content is not the preset display content, the vehicle switches the image quality mode of the second vehicle screen to the first image quality mode, and displays a first prompt message and a target control in the first display area of the second vehicle screen. The first prompt message is used to indicate that the image quality mode of the second vehicle screen has been coordinated with the first vehicle screen, and the target control is used to trigger the image quality mode of the second vehicle screen to switch back from the first image quality mode to the original image quality mode.
[0092] It should be understood that the "first prompt information is used to prompt that the image quality mode of the second vehicle screen is coordinated with the first vehicle screen" in the above solution means that when the second vehicle screen does not display safety information, the image quality mode of the second vehicle screen is switched to the first image quality mode because the image quality mode of the first vehicle screen needs to be switched to the first image quality mode, and the image quality mode of the second vehicle screen needs to be consistent with the image quality mode of the first vehicle screen.
[0093] In the above technical solution, when the second vehicle screen does not display preset display information, the vehicle directly switches the image quality mode of the second vehicle screen to the first image quality mode. This is because switching the image quality of the second vehicle screen when it does not display preset display information will not affect the vehicle user and can also ensure that the image quality of the second vehicle screen is consistent with that of the first vehicle screen. Furthermore, displaying a first prompt message in the first display area of the second vehicle screen can remind the vehicle user of the reason for the image quality switch. In addition, displaying a target control in the first display area can prevent the vehicle user from requesting a restoration of the image quality mode if they are dissatisfied with it.
[0094] In some embodiments, when the currently displayed content is not the preset displayed content, the vehicle switches the image quality mode of the second vehicle screen to the first image quality mode, including: when the currently displayed content is not the preset displayed content, the vehicle determines whether the image quality mode of the second vehicle screen is the first image quality mode; when the image quality mode of the second vehicle screen is not the first image quality mode, the vehicle switches the image quality mode of the second vehicle screen to the first image quality mode.
[0095] In one possible implementation, after the vehicle switches the image quality mode of the second in-vehicle screen to the first image quality mode, the method 200 further includes: the vehicle determining whether the display optimization mode of the second in-vehicle screen is in an on state; if the display optimization mode is in an on state, the vehicle controls the display optimization mode to be in a off state.
[0096] It should be understood that the "display optimization mode" in the above solution includes an eye protection mode and a color correction mode. The eye protection mode is used to reduce the impact of blue light on the eyes by adjusting the screen brightness and screen color temperature to reduce blue light radiation. The color correction mode is used to correct the colors of the images displayed on the in-vehicle screen by adjusting the color distribution or color channels of the displayed image to restore the colors in the real scene.
[0097] In the above technical solution, after switching the image quality mode of the second vehicle screen to the first image quality mode, the method controls the display optimization mode of the second vehicle screen to be turned off. This allows the display optimization mode to be turned off when there is no need for its use, thereby reducing the vehicle's energy consumption.
[0098] It should be understood that the second in-vehicle screen (such as the central control screen) can also serve as the main body for image quality switching. The following description illustrates the control process of the image quality mode of the first in-vehicle screen when the second in-vehicle screen serves as the main body for image quality switching.
[0099] In some embodiments, the method 200 further includes: when the image quality mode of the second vehicle screen is switched to the first image quality mode, the vehicle determines whether the image quality mode of the first vehicle screen is the first image quality mode; when the image quality mode of the first vehicle screen is not the first image quality mode, the vehicle switches the image quality mode of the first vehicle screen to the first image quality mode.
[0100] In the above technical solution, when switching the image quality mode of the second vehicle screen to the first image quality mode, in order to maintain the same image quality effect between the first and second vehicle screens, the image quality mode of the first vehicle screen can be directly switched to the first image quality mode. This is because switching the image quality of the first vehicle screen does not affect the vehicle user.
[0101] Figure 4 This is a schematic diagram of a device for switching image quality provided in an embodiment of this application.
[0102] For example, such as Figure 4 As shown, the device 400 includes:
[0103] The acquisition module 401 is used to acquire the current display content of the second vehicle screen when the image quality mode of the first vehicle screen is switched to the first image quality mode, wherein the image quality mode of the second vehicle screen has a cooperative relationship with the image quality mode of the first vehicle screen.
[0104] The switching module 402 is used to maintain the image quality mode of the second vehicle screen when the current display content is the preset display content.

[0108] Optionally, the display module is specifically used to display a second prompt message in the second display area of the second vehicle screen when the currently displayed content is the preset display content.

The area of the second display area is larger than the area of the first display area of the second vehicle screen. The device 400 further includes a control module, used to maintain the image quality mode of the second vehicle screen if the second prompt message is not confirmed.
[0109] Optionally, the second vehicle screen is a central control screen. The acquisition module 401 is further used to acquire the driving environment parameters of the vehicle when the second prompt information is confirmed. The device 400 also includes: a determination module, used to determine the switching duration based on the driving environment parameters and the screen brightness of the second vehicle screen. The switching duration is the time required to switch the image quality mode of the second vehicle screen from the original image quality mode to the first image quality mode.

[0111] Optionally, the determining module is further configured to: if a first trip corresponding to the driving segment exists in the vehicle's historical travel history, determine a first average duration for which the driver repeatedly looks at the second in-vehicle screen during the first trip, and determine the first average duration as the second target duration; or, if the first trip does not exist in the historical travel history but a second trip corresponding to other driving segments exists, determine a second average duration for which the driver repeatedly looks at the second in-vehicle screen during the second trip, and determine the second average duration as the second target duration; or, if neither the first trip nor the second trip exists in the historical travel history, obtain a third average duration for which other drivers repeatedly look at the second in-vehicle screen when other vehicles are driving on the driving segment, and determine the third average duration as the second target duration.

5. The method according to claim 1 or 2, characterized in that, The area of the second display area is larger than the area of the first display area on the second vehicle screen.
6. The method according to claim 5, characterized in that, The second in-vehicle screen is a central control screen, and the switching time is the time required to switch the image quality mode of the second in-vehicle screen from the original image quality mode to the first image quality mode.
7. The method according to claim 6, characterized in that, The method for determining the duration of the second target includes: If a first trip corresponding to the aforementioned route segment exists in the vehicle's historical travel history, determine the first average duration for which the driver repeatedly looks at the second in-vehicle screen during that first trip, and set this first average duration as the second target duration; or, If the first trip does not exist in the historical travel records but a second trip exists corresponding to other travel segments, determine the second average duration of the driver's multiple glances at the second in-vehicle screen during the second trip, and set the second average duration as the second target duration; or, If neither the first trip nor the second trip exists in the historical travel history, obtain the third average duration of time other drivers repeatedly look at the second in-vehicle screen while other vehicles are traveling on the same road segment, and determine the third average duration as the second target duration.
8. A device for switching image quality, characterized in that, The device includes: The acquisition module is used to acquire the current display content of the second vehicle screen when the image quality mode of the first vehicle screen is switched to the first image quality mode. The image quality mode of the second vehicle screen has a cooperative relationship with the image quality mode of the first vehicle screen. The processing module is configured to: display a second prompt message on a second display area of the second vehicle screen when the currently displayed content is a preset display content; maintain the image quality mode of the second vehicle screen if the second prompt message is not confirmed; and determine a switching duration based on driving environment parameters and the screen brightness of the second vehicle screen if the second prompt message is confirmed. The driving environment parameters include the congestion level of the road segment the vehicle is traveling on and the ambient brightness inside the vehicle. Determining the switching duration based on the driving environment parameters and the screen brightness of the second vehicle screen includes: determining a first target duration as the switching duration if the congestion level is less than a first preset level, where the first target duration is the vehicle's... The shortest duration for switching image quality modes; when the congestion level is greater than or equal to the first preset level, the deviation of the screen brightness from the ambient brightness is determined, and the product of the second target duration and the deviation is determined as the adjustment duration, wherein the second target duration is related to the historical duration of the driver's gaze at the second in-vehicle screen; when the screen brightness is greater than the ambient brightness, the sum of the second target duration and the adjustment duration is determined as the switching duration; when the screen brightness is less than or equal to the ambient brightness, the difference between the second target duration and the adjustment duration is determined as the switching duration; based on the switching duration, the image quality mode of the second in-vehicle screen is switched to the first image quality mode; The preset display content is used to indicate that the first image quality mode is not applicable to the vehicle user corresponding to the second vehicle screen. The second prompt information is used to indicate that the second vehicle screen is displaying the preset display content and that it is not recommended to switch the image quality mode in order not to affect the vehicle user's use of the second vehicle screen. It is also used to confirm whether to switch the image quality mode of the second vehicle screen. The confirmation of the second prompt information is used to indicate that the vehicle user needs to switch the image quality mode of the second vehicle screen.
9. A vehicle, characterized in that, The vehicles include: Memory, used to store executable program code; A processor for calling and running the executable program code from the memory, causing the vehicle to perform the method as described in any one of claims 1 to 7.
