According to the method, whether the image quality modes of the first vehicle-mounted screen and the second vehicle-mounted screen should be coordinated or not can be controlled based on the actual vehicle using scene, so that the vehicle using experience of a vehicle user can be improved.

Description

Technical Field

[0001] The present application relates to the field of vehicles, and more specifically, to a method, device and vehicle for switching image quality in the field of vehicles. Background Art

[0002] With the continuous advancement of vehicle technology and the improvement of people's living standards, the audience of vehicles is becoming more and more extensive. However, there are also more and more vehicle-related problems, including the image quality problem when watching videos on the in-car screen. These problems may affect the user's car experience. Summary of the invention

[0003] The present application provides a method, device and vehicle for switching image quality, which can improve the vehicle user's vehicle experience.

[0004] In a first aspect, a method for switching picture quality is provided, the method comprising: when the picture quality mode of a first vehicle-mounted screen is switched to a first picture quality mode, obtaining the current display content of a second vehicle-mounted screen, the picture quality mode of the second vehicle-mounted screen being in a collaborative relationship with the picture quality mode of the first vehicle-mounted screen; when the current display content is the preset display content, maintaining the picture quality mode of the second vehicle-mounted screen, and the preset display content is used to indicate that the first picture quality mode is not applicable to the vehicle user corresponding to the second vehicle-mounted screen.

[0005] In the above technical solution, when the picture quality mode of the first vehicle-mounted screen is switched to the first picture quality mode, the current display content on the second vehicle-mounted screen is analyzed. When the current display content on the second vehicle-mounted screen is the preset display content, the picture quality mode of the second vehicle-mounted screen is controlled to be the original picture quality mode, that is, the current picture quality mode is maintained, wherein the picture quality mode of the second vehicle-mounted screen is in a collaborative relationship with the picture quality mode of the first vehicle-mounted screen. This can avoid the situation where the picture quality is switched when the vehicle user is looking at the second vehicle-mounted screen, resulting in the switched picture quality mode being unsuitable for the vehicle user. When the vehicle user is a driver, it causes the driver's attention to be distracted and the driver's vision to be disturbed, thereby affecting the vehicle driving safety and even causing a traffic accident. Therefore, the method can control whether the picture quality modes of the first vehicle-mounted screen and the second vehicle-mounted screen should be coordinated based on the actual vehicle use scenario, rather than controlling the picture quality mode of the second vehicle-mounted screen to be consistent with the picture quality mode of the first vehicle-mounted screen in any scenario, which can improve the vehicle user's car experience.

[0006] In combination with the first aspect, in some possible implementations, the first picture quality mode is a standard picture quality mode, and a method for determining whether the picture quality mode of the first vehicle screen is switched to the first picture quality mode includes: responding to a play instruction for a first video of a target type on the first vehicle screen, determining that the picture quality mode of the first vehicle screen is switched to a standard picture quality mode, and the target type is a video type played in the standard picture quality mode.

[0007] In the above technical solution, when the first video of the target type on the first vehicle screen is triggered, the method can switch the image quality mode of the first vehicle screen to the standard image quality mode, and can play the first video in the standard image quality mode. This can meet the vehicle user's demand for playing the first video of the target type on the first 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 combination with the first aspect, in some possible implementations, the method also includes: when the currently displayed content is not the preset display content, switching the picture quality mode of the second vehicle screen to the first picture quality mode, and displaying a first prompt message and a target control in the first display area of ​​the second vehicle screen, the first prompt message being used to prompt that the picture quality mode of the second vehicle screen has been coordinated with the first vehicle screen, and the target control being used to trigger the picture quality mode of the second vehicle screen to switch from the first picture quality mode back to the original picture quality mode.

[0009] In the above technical solution, when the second vehicle-mounted screen does not display the preset display information, the vehicle in the method directly switches the picture quality mode of the second vehicle-mounted screen to the first picture quality mode. This is because when the second vehicle-mounted screen does not display the preset display information, switching the picture quality of the second vehicle-mounted screen will not affect the vehicle user, and can also ensure that the picture quality of the second vehicle-mounted screen is consistent with that of the first vehicle-mounted screen. Furthermore, the first prompt information is displayed in the first display area on the second vehicle-mounted screen, which can remind the vehicle user of the reason why the second vehicle-mounted screen switches the picture quality. In addition, the target control is also displayed on the first display area, which can prevent the vehicle user from being able to restore the picture quality mode when he is dissatisfied with the picture quality mode of the second vehicle-mounted screen.

[0010] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, after the picture quality mode of the second vehicle-mounted screen is switched to the first picture quality mode, the method also includes: determining whether the display optimization mode of the second vehicle-mounted screen is in an on state, and the display optimization mode is used to optimize the screen parameters of the second vehicle-mounted screen; when the display optimization mode is in an on state, controlling the display optimization mode to be in an off state.

[0011] In the above technical solution, after the image quality mode of the second vehicle-mounted screen is switched to the first image quality mode, the method controls the display optimization mode of the second vehicle-mounted screen to be turned off. This can turn off the display optimization mode when there is no need to use the display optimization mode, which can reduce the energy consumption of the vehicle.

[0012] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, when the currently displayed content is the preset display content, the picture quality mode of the second vehicle-mounted screen is maintained, including: when the currently displayed content is the preset display content, a second prompt message is displayed in the second display area of ​​the second vehicle-mounted screen, the second prompt message is used to prompt that the second vehicle-mounted screen is displaying the preset display content and in order not to affect the vehicle user's use of the second vehicle-mounted screen, it is not recommended to switch the picture quality mode, and is used to confirm whether to switch the picture quality mode of the second vehicle-mounted screen, and the area of ​​the second display area is larger than the area of ​​the first display area on the second vehicle-mounted screen; when the second prompt message is not confirmed, the picture quality mode of the second vehicle-mounted screen is maintained.

[0013] In the above technical solution, when the current display content of the second vehicle-mounted screen is the preset display information, the vehicle in the method displays a second prompt message on the second display area of ​​the second vehicle-mounted screen. The second prompt message is used to prompt that the second vehicle-mounted screen is displaying the preset display content and that it is not recommended to switch the picture quality mode in order not to affect the vehicle user's use of the second vehicle-mounted screen. This enables the vehicle user to know the reason why the second vehicle-mounted screen does not switch the picture quality. In addition, the second prompt message is also used to confirm whether to switch the picture quality of the second vehicle-mounted screen. This can provide the vehicle user with the right to independently choose whether to switch the picture quality of the second vehicle-mounted screen, and the vehicle user can switch or not based on his own needs. Therefore, this method can, to a certain extent, not only ensure that the vehicle user's use of the second vehicle-mounted screen is not affected, but also meet the vehicle user's needs for autonomous switching of the picture quality mode of the vehicle-mounted screen.

[0014] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the second vehicle-mounted screen is a central control screen, and the method also includes: when the second prompt information is confirmed, obtaining the driving environment parameters of the vehicle; based on the driving environment parameters and the screen brightness of the second vehicle-mounted screen, determining the switching duration, the switching duration being the duration required to switch the picture quality mode of the second vehicle-mounted screen from the original picture quality mode to the first picture quality mode; based on the switching duration, switching the picture quality mode of the second vehicle-mounted screen to the first picture quality mode.

[0015] In the above technical solution, when the driver needs to switch the picture quality mode of the second vehicle-mounted screen, the vehicle determines the switching duration based on the driving environment parameters of the vehicle and the screen brightness of the second vehicle-mounted screen. This is because the driver needs to obtain safety information from the second vehicle-mounted screen during vehicle driving. Therefore, the influence of the screen brightness of the second vehicle-mounted screen is considered in the determination of the switching duration. In addition, the driver has been in the ambient brightness for a long time and has adapted to the ambient brightness. In the process of switching the picture quality mode of the second vehicle-mounted screen, different switching durations have different effects on the driver's attention and vision. In order to make the effect of picture quality switching easier and faster for the driver to adapt, the switching duration is also related to the ambient brightness. Therefore, the vehicle in the method switches the picture quality mode of the second vehicle-mounted screen to the first picture quality mode based on the switching duration, which can avoid affecting the driver's attention and vision, ensure that the driver can clearly view the safety information on the second vehicle-mounted screen, and improve the safety of vehicle driving.

[0016] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the driving environment parameters include the congestion level of the vehicle's driving section and the ambient brightness inside the vehicle, and the switching duration is determined based on the driving environment parameters and the screen brightness of the second vehicle-mounted screen, including: when the congestion level is less than a first preset level, determining a first target duration as the switching duration, and the first target duration is the shortest duration when the vehicle switches the picture quality mode; when the congestion level is greater than or equal to the first preset level, determining the deviation amplitude of the screen brightness relative to the ambient brightness, and determining the product of the second target duration and the deviation amplitude as the adjustment duration, and the second target duration is related to the historical duration of the driver's gaze on the second vehicle-mounted 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.

[0017] In the above technical solution, when the congestion level of the driving section is very small, the driving process of the vehicle is relatively smooth, the driving speed is fast, and the driver's attention is mainly focused on the road. Therefore, a faster image quality switching can be allowed, and a short switching time can be determined. When the congestion level of the driving section is large, the driver needs to frequently operate the vehicle and view safety information (obtain traffic information, navigation instructions or entertainment content) through the second vehicle-mounted screen. Therefore, a longer image quality switching can be allowed, and a longer switching time can be determined. Specifically, the driver is more adapted to the ambient brightness. When the ambient brightness is low, the slower switching speed (longer switching time) in this method can allow the driver's eyes to have enough time to adapt to the changes in the picture. For example, when switching from one brightness and color mode to another mode, if it is a slow switch, the driver's visual system can smoothly transition without sudden visual impact, which is more conducive to accurately reading the information on the central control screen after switching. When the ambient brightness is large, the method adopts a faster switching speed (shorter switching time) because the driver's sight conditions are better. This can reduce the burden on the processor.

[0018] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the method for determining the second target duration includes: when there is a first trip corresponding to the driving section in the historical trip of the vehicle, determining the first average duration of the driver's multiple gazes at the second vehicle-mounted screen in the first trip, and determining the first average duration as the second target duration; or, when the first trip does not exist in the historical trip and there is a second trip corresponding to other driving sections, determining the second average duration of the driver's multiple gazes at the second vehicle-mounted screen in the second trip, and determining the second average duration as the second target duration; or, when the first trip does not exist in the historical trip and the second trip does not exist, obtaining the third average duration of other drivers' multiple gazes at the second vehicle-mounted screen when other vehicles are driving on the driving section, 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 (the first average duration of looking at the second vehicle-mounted screen) in the historical journey (first journey) on the driving section. This can take into account the driver's special preferences when using the second vehicle-mounted screen, and the setting based on personal driving habits can also improve the driver's car experience. When the driver has not traveled the driving section in the historical period, the method determines the second target duration by the driver's driving habits when driving other sections (the second average duration of looking at the second vehicle-mounted screen). Compared with the first average duration, the accuracy of the second average duration is poor, because the road conditions of the driving section may be complex, while the road conditions of other sections 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 section (the third average duration of looking at the second vehicle-mounted screen). Although this method does not take into account the driver's driving habits, it can also avoid the situation where the second target duration cannot be determined when the first journey does not exist.

[0020] In a second aspect, a device for switching picture quality is provided, which includes: an acquisition module, used to acquire the current display content of a second vehicle-mounted screen when the picture quality mode of the first vehicle-mounted screen is switched to the first picture quality mode, and the picture quality mode of the second vehicle-mounted screen has a collaborative relationship with the picture quality mode of the first vehicle-mounted screen; a switching module, used to maintain the picture quality mode of the second vehicle-mounted screen when the current display content is the preset display content, and the preset display content is used to indicate that the first picture quality mode is not applicable to the vehicle user corresponding to the second vehicle-mounted screen.

[0021] In combination with the second aspect, in some possible implementations, the device also includes: a determination module, used to determine that the picture quality mode of the first vehicle screen is switched to a standard picture quality mode in response to a play instruction for a first video of a target type on the first vehicle screen, and the target type is the type of video played in the standard picture quality mode.

[0022] In combination with the second aspect and the above-mentioned implementation methods, in some possible implementation methods, the device also includes: a display module, used to switch the picture quality mode of the second vehicle screen to the first picture quality mode when the currently displayed content is not the preset display content, and display a first prompt information and a target control in the first display area of ​​the second vehicle screen, the first prompt information being used to prompt that the picture quality mode of the second vehicle screen has been coordinated with the first vehicle screen, and the target control being used to trigger the picture quality mode of the second vehicle screen to switch from the first picture quality mode back to the original picture quality mode.

[0023] In combination with the second aspect and the above-mentioned implementation methods, in some possible implementation methods, after the picture quality mode of the second vehicle-mounted screen is switched to the first picture quality mode, the determination module is also used to determine whether the display optimization mode of the second vehicle-mounted screen is in an on state, and the display optimization mode is used to optimize the screen parameters of the second vehicle-mounted screen; the switching module is also used to control the display optimization mode to be in an off state when the display optimization mode is in an on state.

The device also includes: a control module, which is used to maintain the picture quality mode of the second vehicle-mounted screen when the second prompt message is not confirmed.

[0035] The technical solution in the present application will be described clearly and in detail below in conjunction with the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0036] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0037] Figure 1 It is a schematic diagram of a scenario of using a vehicle provided in an embodiment of the present application.

[0038] For example, Figure 1 As shown, the front screen in vehicle A includes a central control screen and a co-pilot screen. The central control screen is usually installed in the central area of ​​the center console of the vehicle, that is, the area between the main driver's seat and the co-pilot seat, which is convenient for both the driver and the co-pilot user to operate and view. The co-pilot screen is usually installed on the dashboard in front of the co-pilot seat, which is convenient for the co-pilot user to operate the co-pilot screen, and it will not affect the driver's line of sight and operation. The position of the central control screen is close to that of the co-pilot screen.

[0039] In order to make the image quality effects between the central control screen and the co-pilot screen in the front screen consistent, it is usually stipulated that the image quality of the display screen of the co-pilot screen is coordinated with that of the display screen of the central control screen, that is, it is updated or switched synchronously. However, there will be some problems. In some embodiments, no matter what kind of screen information is displayed on the central control screen, the image quality will be switched along with the co-pilot screen. This embodiment will cause the driver who is looking at the central control screen to be unable to adapt to the switching effect of the image quality in time, and the driver's eyes will feel uncomfortable. For example, the eyes experience temporary visual blurring, slight tingling, and in extreme cases, it may even cause dizziness.

[0040] The following description will be made using the above-mentioned central control screen and co-pilot screen as examples. However, it should be understood that the present application is not limited to this. In fact, the present application is applicable to any two or more screens whose picture quality can be coordinated with each other. For example, for the rear screens including the rear left ceiling screen and the rear right ceiling screen, when one of the screens is used by children and the other is used by adults, children and adults have different needs at least in terms of eye protection and color. If an adult adjusts the picture quality of the screen according to his or her own needs, the picture quality may not be suitable for children. In this case, the picture quality of the screen that the child is using should obviously not be automatically adjusted synchronously.

[0041] In order to solve the above problems, this application provides a method for switching image quality to improve the vehicle user's vehicle experience. The specific implementation steps are as follows: Figure 2 shown.

[0042] Figure 2 It is a schematic flowchart of a method for switching image quality provided in an embodiment of the present application.

[0043] It should be understood that the method for switching image quality provided in the embodiment of the present application can be applied to the following examples: Figure 1 The vehicle shown (e.g., vehicle A). Specifically, the method for switching image quality can be applied to a target controller in the vehicle. The target controller is any one of a vehicle controller and a body domain controller. The body domain controller is used to control various vehicle components in the vehicle. In the method for switching image quality of the present application, the vehicle component is a vehicle screen, specifically a first vehicle screen and a second vehicle screen.

[0044] For example, Figure 2 As shown, the method 200 includes step 201 and step 202 .

[0045] Step 201, when the picture quality mode of the first vehicle-mounted screen is switched to the first picture quality mode, the vehicle obtains the current display content of the second vehicle-mounted screen, and the picture quality mode of the second vehicle-mounted screen has a collaborative relationship with the picture quality mode of the first vehicle-mounted screen.

[0046] It should be understood that the "picture quality mode of the second vehicle-mounted screen and the picture quality mode of the first vehicle-mounted screen have a collaborative relationship" in the above step 201 is used to indicate that the picture quality mode between the second vehicle-mounted screen and the first vehicle-mounted screen can be kept consistent. Normally, the position of the second vehicle-mounted screen is adjacent to the position of the first vehicle-mounted screen.

[0047] It should also be understood that the "image quality mode" in the above step 201 refers to the different processing methods and parameter settings used by the vehicle screen when displaying images to optimize the quality of the displayed image. The image quality mode includes standard image quality mode, vivid image quality mode, soft image quality mode, natural image quality mode and game image quality mode. Among them, the standard image quality mode is used to provide balanced image quality and performance; the vivid image quality mode is used to enhance the color saturation and vividness of the image; the soft image quality mode is used to provide a softer and more delicate image effect, and reduce the sharpening and contrast of the image; the natural image quality mode is used to provide a light and color performance that is closer to nature; the game image quality mode is used to provide faster response speed and lower latency.

[0048] In some embodiments, the vehicle in step 201 obtains the current display content of the second vehicle-mounted screen, including: the vehicle obtains the target application built into the vehicle's multimedia system to obtain the current display content of the second vehicle-mounted screen.

[0049] In one possible implementation, the first picture quality mode is a standard picture quality mode, and the method for determining whether the picture quality mode of the first vehicle screen is switched to the first picture quality mode in step 202 includes: the vehicle responds to a play instruction for a first video of a target type on the first vehicle screen, and determines that the picture quality mode of the first vehicle screen is switched to the standard picture quality mode, and the target type is the type of video played in the standard picture quality mode.

[0050] It should be understood that the "target type is a video type played in standard quality mode" in the above solution can be understood as: the target type of video is best displayed 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 (such as HDR video) has a dependent relationship with the standard quality mode and has a mutually exclusive relationship with other quality modes (bright quality mode, soft quality mode, natural quality mode and game quality mode).

[0051] In some embodiments, the co-pilot user in the vehicle triggers the play command by voice; or, the co-pilot user triggers the play command by clicking on the first video of the target type; or, the co-pilot user triggers the play command by a selection gesture, which is an open palm gesture.

[0052] Figure 3 It is a schematic diagram of an image quality function in a vehicle provided in an embodiment of the present application.

[0053] For example, Figure 3 As shown, the image quality function in the vehicle serves the display image (e.g., video) in the video playback component on the vehicle screen. The vehicle screen includes a first vehicle screen and a second vehicle screen, and the video types that can be played on the vehicle screen include HDR video types and other video types, and the other video types include standard dynamic range (SDR) video types and high-definition Blu-ray video types. The vehicle can control the image quality mode, eye protection mode, and color correction mode of the vehicle screen through the image quality control component. Among them, the image quality mode includes a standard image quality mode and other image quality modes, and the other image quality modes include a vivid image quality mode, a soft image quality mode, a natural image quality mode, and a game image quality mode.

[0054] Step 202, when the current display content is the preset display content, the vehicle maintains the image quality mode of the second vehicle-mounted screen, and the preset display content is used to indicate that the first image quality mode is not suitable for the vehicle user corresponding to the second vehicle-mounted screen.

[0055] It should be understood that "maintaining the picture quality mode of the second vehicle-mounted screen" in the above step 202 means not changing the original picture quality mode of the second vehicle-mounted screen, and controlling the picture quality mode of the second vehicle-mounted screen to remain the original picture quality mode. In some embodiments, the first vehicle-mounted screen is the co-pilot screen, and the second vehicle-mounted screen is the central control screen. In some embodiments, the preset display content includes navigation content, reversing images, tire status, and all-round images of the vehicle when moving forward. The driver needs to obtain safety information from the second vehicle-mounted screen to assist in vehicle driving. Therefore, arbitrarily switching the picture quality mode of the second vehicle-mounted screen will distract the driver's attention and interfere with the driver's vision, thereby affecting the safety of vehicle driving. Therefore, the picture quality mode of the second vehicle-mounted screen cannot be switched arbitrarily.

[0056] It should also be understood that 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-mounted screen" in the above step 202 means that if the image quality mode of the second vehicle-mounted screen is switched to the first image quality mode, it will affect the vehicle user's current use of the second vehicle-mounted screen. In some embodiments, the first vehicle-mounted screen is the rear left ceiling screen in the vehicle, the second vehicle-mounted screen is the rear screen of the rear right ceiling screen in the vehicle, the first vehicle-mounted screen is used by children, and the second vehicle-mounted screen is used by adults. Children and adults have different needs for eye protection and color. If adults switch the image quality mode of the second vehicle-mounted screen to the first image quality mode according to their own needs, switching the image quality mode of the first vehicle-mounted screen to the first image quality mode may not be applicable to children.

[0057] In one possible implementation, in step 202, when the current display content is the preset display content, the vehicle maintains the picture quality mode of the second vehicle screen, including: when the current display content is the preset display content, the vehicle displays a second prompt message in the second display area on the second vehicle screen, the second prompt message being used to prompt that the second vehicle screen is displaying the preset display content and that it is not recommended to switch the picture quality mode in order not to affect the vehicle user's use of the second vehicle screen, and being used to confirm whether to switch the picture quality mode of the second vehicle screen, the area of ​​the second display area being larger than the area of ​​the first display area on the second vehicle screen; when the second prompt message is not confirmed, the vehicle maintains the picture quality mode of the second vehicle screen.

[0058] It should be understood that "the area of ​​the second display area is larger than the area of ​​the first display area on the second vehicle-mounted screen" in the above scheme can be regarded as the second display area being more eye-catching than the first display area, and compared with the first display area, the second display area can preferentially attract the driver's attention.

[0059] It should also be understood that the "second prompt information" in the above scheme has two functions: first, it prompts that the second vehicle screen is displaying the preset display content and in order not to affect the vehicle user's use of the second vehicle screen, it is not recommended to switch the picture quality mode; second, it gives the vehicle user the right to choose whether to switch the picture quality of the second vehicle screen.

[0060] In the above technical solution, when the current display content of the second vehicle-mounted screen is the preset display content, the vehicle in the method displays a second prompt message on the second display area of ​​the second vehicle-mounted screen. The second prompt message is used to prompt that the second vehicle-mounted screen is displaying the preset display content and that it is not recommended to switch the picture quality mode in order not to affect the vehicle user's use of the second vehicle-mounted screen. This enables the vehicle user to know the reason why the second vehicle-mounted screen does not switch the picture quality. In addition, the second prompt message is also used to confirm whether to switch the picture quality of the second vehicle-mounted screen. This can provide the vehicle user with the right to independently choose whether to switch the picture quality of the second vehicle-mounted screen, and the vehicle user can switch or not based on his own needs. Therefore, this method can, to a certain extent, not affect the vehicle user's use of the second vehicle-mounted screen, but also meet the vehicle user's needs for autonomous switching of the picture quality mode of the vehicle-mounted screen.

[0061] In some embodiments, the vehicle displays the second prompt information in the second display area on the second vehicle-mounted screen, including: the vehicle displays the second prompt information in the upper middle area of ​​the second vehicle-mounted screen.

[0062] In some embodiments, the vehicle displays the second prompt information in the second display area on the second vehicle-mounted screen, including: the vehicle displays the second prompt information in the second display area on the second vehicle-mounted screen in a pop-up window.

[0063] In one possible implementation, the second vehicle-mounted screen is a central control screen, and the method 200 also includes: when the second prompt information is confirmed, the vehicle obtains the driving environment parameters of the vehicle; the vehicle determines the switching duration based on the driving environment parameters and the screen brightness of the second vehicle-mounted screen, and the switching duration is the duration required to switch the picture quality mode of the second vehicle-mounted screen from the original picture quality mode to the first picture quality mode; based on the switching duration, the vehicle switches the picture quality mode of the second vehicle-mounted screen to the first picture quality mode.

[0064] It should be understood that in the above scheme, after the second prompt information is confirmed, it indicates that the driver needs to switch the picture quality mode of the second vehicle-mounted screen. In order to reduce the impact on the driver's attention and vision when the picture quality of the second vehicle-mounted screen is switched, the vehicle determines the switching duration based on the vehicle's driving environment parameters and the screen brightness of the second vehicle-mounted screen, and switches the picture quality of the second vehicle-mounted screen according to the switching duration.

[0065] It should also be understood that the "driving environment parameters" in the above solution refer to environmental parameters that affect the driver's visual behavior and driving experience during vehicle driving. The driving environment parameters include at least one of the congestion level, bumpiness and road type of the vehicle's driving section, 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 picture quality mode of the second vehicle-mounted screen, the vehicle determines the switching duration based on the driving environment parameters of the vehicle and the screen brightness of the second vehicle-mounted screen. This is because the driver needs to obtain safety information from the second vehicle-mounted screen during vehicle driving. Therefore, the influence of the screen brightness of the second vehicle-mounted screen is considered in the determination of the switching duration. In addition, the driver has been in the ambient brightness for a long time and has adapted to the ambient brightness. In the process of switching the picture quality mode of the second vehicle-mounted screen, different switching durations have different effects on the driver's attention and vision. In order to make the effect of picture quality switching easier and faster for the driver to adapt, the switching duration is also related to the ambient brightness. Therefore, the vehicle in the method switches the picture quality mode of the second vehicle-mounted screen to the first picture quality mode based on the switching duration, which can avoid affecting the driver's attention and vision, ensure that the driver can clearly view the safety information on the second vehicle-mounted screen, and improve the safety of vehicle driving.

[0067] The process of "determining the switching duration" is described below according to different situations.

[0068] Case 1: Driving environment parameters include the congestion level of the driving section and the ambient brightness inside the vehicle.

[0069] In a possible implementation, the driving environment parameters include the congestion level of the vehicle's driving section 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 vehicle-mounted screen, including: when the congestion level is less than a first preset level, the vehicle determines a first target duration as the switching duration, and the first target duration is the shortest duration when the vehicle switches the picture quality mode; when the congestion level is greater than or equal to the first preset level, the vehicle determines the deviation amplitude of the screen brightness relative to the ambient brightness, and determines the product of the second target duration and the deviation amplitude as the adjustment duration, and the second target duration is related to the historical duration of the driver's gaze on the second vehicle-mounted screen; when the screen brightness is greater than the ambient brightness, the vehicle determines the sum of the second target duration and the adjustment duration as the switching duration; when the screen brightness is less than or equal to the ambient brightness, the vehicle determines the difference between the second target duration and the adjustment duration as the switching duration.

[0070] It should be understood that in the above scheme, "the degree of congestion of the vehicle's driving section" refers to the degree to which the vehicle's driving speed and traffic capacity on the driving section are restricted. Among them, the traffic capacity refers to the number of vehicles passing through the driving section per unit time, and the unit time is one hour. "The ambient brightness inside the vehicle" refers to the ambient brightness inside the cabin. "The first preset degree" refers to the degree to which the vehicle's driving speed on the driving section is greater than the preset speed and the traffic capacity is greater than the preset number of vehicles. In some embodiments, the preset speed is 60 kilometers per hour, and the preset number of vehicles is 1,000 vehicles per hour.

[0071] It should also be understood that the "second target duration" in the above scheme is greater than the "first target duration".

[0072] In the above technical solution, when the congestion level of the driving section is very small, the driving process of the vehicle is relatively smooth, the driving speed is fast, and the driver's attention is mainly focused on the road. Therefore, a faster image quality switching can be allowed, and a short switching time can be determined. When the congestion level of the driving section is large, the driver needs to frequently operate the vehicle and view safety information (obtain traffic information, navigation instructions or entertainment content) through the second vehicle-mounted screen. Therefore, a longer image quality switching can be allowed, and a longer switching time can be determined. Specifically, the driver is more adapted to the ambient brightness. When the ambient brightness is low, the slower switching speed (longer switching time) in this method can allow the driver's eyes to have enough time to adapt to the changes in the picture. For example, when switching from one brightness and color mode to another mode, if it is a slow switch, the driver's visual system can smoothly transition without sudden visual impact, which is more conducive to accurately reading the information on the central control screen after switching. When the ambient brightness is large, the method adopts a faster switching speed (shorter switching time) because the driver's sight conditions are better. This can reduce the burden on the processor.

[0073] In some embodiments, the method for determining the congestion level of the driving section includes: the vehicle obtains the actual driving speed of the vehicle and the actual number of vehicles passing through the driving section per unit time; the vehicle determines the ratio between the actual driving speed and the free flow speed as the speed ratio, and determines the ratio between the actual number of vehicles and the theoretical number of passing vehicles as the flow ratio, the free flow speed being the normal driving speed of the driving section in a non-congested condition, and the theoretical number of passing vehicles being the maximum number of vehicles that can pass through the driving section per unit time under ideal conditions; the vehicle determines the congestion level of the driving section based on the speed ratio and the flow ratio.

[0074] It should be understood that in the above scheme, the "speed ratio" represents the ratio between the actual driving speed and the 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. The "flow ratio" represents the ratio of the actual number of vehicles (actual traffic volume) to the theoretical number of vehicles passing (ideal normal traffic volume). The closer the flow ratio is to 1, the closer the actual traffic volume of the driving section is to its theoretical traffic volume, and the congestion level is moderate; if the flow ratio is greater than 1, it means that the actual traffic volume exceeds its theoretical traffic volume, and the congestion level is high.

[0075] In some embodiments, the free flow speed is the speed limit of the driving section.

[0076] In some embodiments, the vehicle determines the congestion level of the driving section based on the speed ratio and the flow ratio, including: the vehicle determines the congestion level of the driving section based on the following formula (1);

[0077]

[0078] Among them, C I is the congestion level of the driving section, v is the actual driving speed, and v t is the free flow speed, q is the actual number of vehicles, q t is the theoretical number of vehicles passing through.

[0079] It should be understood that the first half of formula (1) It is used to indicate the contribution of the speed ratio. The smaller the speed ratio, the larger the value of the first half, the higher the congestion level, and the smaller the value of the second half. Used to indicate the part where the traffic ratio exceeds the theoretical capacity. The larger the value in the second half, the higher the congestion level.

[0080] In some embodiments, the vehicle determines the deviation amplitude of the screen brightness relative to the ambient brightness, including: the vehicle determines the difference between the screen brightness and the ambient brightness as the brightness deviation; the vehicle determines the ratio between the brightness deviation and the ambient brightness as the deviation amplitude.

[0081] In one possible implementation, the method for determining the second target duration includes: when there is a first trip corresponding to the driving section in the historical trip of the vehicle, the vehicle determines the first average duration that the driver repeatedly stares at the second vehicle-mounted screen during the first trip, and determines the first average duration as the second target duration; or, when the first trip does not exist in the historical trip and there is a second trip corresponding to other driving sections, the vehicle determines the second average duration that the driver repeatedly stares at the second vehicle-mounted screen during the second trip, and determines the second average duration as the second target duration; or, when the first trip and the second trip do not exist in the historical trip, the vehicle obtains the third average duration that other drivers of other vehicles repeatedly stare at the second vehicle-mounted screen when they travel on the driving section, and determines the third average duration as the second target duration.

[0082] It should be understood that the "first trip corresponding to the driving section in the historical trips of the vehicle" in the above solution can be simply understood as the trips of the vehicle using the driving section in the historical period, and the number of trips of the first trip is greater than or equal to 1. In a single trip, for driving safety, the driver needs to look at the second vehicle screen multiple times to obtain safety information from the second vehicle screen.

[0083] In the above technical solution, the second target duration is determined by the driver's driving habits (the first average duration of looking at the second vehicle-mounted screen) in the historical journey (first journey) on the driving section. This can take into account the driver's special preferences when using the second vehicle-mounted screen, and the setting based on personal driving habits can also improve the driver's car experience. When the driver has not traveled the driving section in the historical period, the method determines the second target duration by the driver's driving habits when driving other sections (the second average duration of looking at the second vehicle-mounted screen). Compared with the first average duration, the accuracy of the second average duration is poor, because the road conditions of the driving section may be complex, while the road conditions of other sections 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 section (the third average duration of looking at the second vehicle-mounted screen). Although this method does not take into account the driver's driving habits, it can also 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 drivers includes: the vehicle determines the gender, driving experience and age group of the driver; the vehicle compares the gender with the sample genders of multiple sample drivers, and determines multiple first candidate drivers with the same gender from the multiple sample drivers; the vehicle compares the driving experience with the sample driving experience of the multiple first candidate drivers, and determines multiple second candidate drivers with the same driving experience from the multiple first candidate drivers; the vehicle compares the age group with the sample age group of the multiple second candidate drivers, determines multiple third candidate drivers with the same age group from the multiple second candidate drivers, and determines the multiple third candidate drivers as the other drivers.

[0085] Case 2: The driving environment parameters also include the bumpiness of the road the vehicle is traveling on.

[0086] In some embodiments, the driving environment parameters include the congestion level, the bumpiness level and the ambient brightness inside the vehicle of the driving section of the vehicle. The vehicle determines the switching duration based on the driving environment parameters and the screen brightness of the second vehicle-mounted screen, including: when the congestion level is less than a first preset level and the bumpiness level is less than a second preset level, the vehicle determines a first target duration as the switching duration, and the first target duration is the shortest duration when the vehicle switches the image quality mode; when the congestion level is greater than or equal to the first preset level and the bumpiness level is greater than or equal to the second preset level, the vehicle determines the deviation amplitude of the screen brightness relative to the ambient brightness, and determines the product of the second target duration and the deviation amplitude as the first adjustment duration, and the second target duration is related to the historical duration of the driver's gaze on the second vehicle-mounted screen; the vehicle determines the product of the first adjustment duration and the bumpiness factor as the second adjustment duration, and the bumpiness factor is related to the bumpiness 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. as the switching duration; when the screen brightness is less than or equal to the ambient brightness, the vehicle determines the difference between the second target duration and the second adjustment duration as the switching duration; when the congestion level is less than the first preset level and the bumpiness 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 sum of the first target duration and the second adjustment duration as the switching duration; when the screen brightness is less than or equal to the ambient brightness, the vehicle determines the difference between the first target duration and the second adjustment duration as the switching duration; when the congestion level is greater than or equal to the first preset level and the bumpiness 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 sum of the second target duration and the first adjustment duration as the switching duration; when the screen brightness is less than or equal to the ambient brightness, the vehicle determines the difference between the second target duration and the first adjustment duration as the switching duration.

[0087] It should be understood that the "bumping degree of the vehicle's driving section" in the above solution refers to the vibration degree caused by the uneven road surface of the driving section during the vehicle's driving. In addition, the bump factor is equal to the sum of a preset value and the bumping degree, and the preset value is 1.

[0088] In the above technical solution, when the driving environment parameter also includes the degree of bumpiness of the driving section of the vehicle, the method considers the determination process of the switching duration in various cases. Specifically, when the congestion degree and the bumpiness degree are small when the vehicle is driving, the driving process of the vehicle is relatively smooth, the driving speed is fast, and the driver's attention is mainly focused on the road. Therefore, it is allowed to switch the image quality faster and determine a short switching duration. When the congestion degree and the bumpiness degree are large when the vehicle is driving, the driver needs to operate the vehicle more frequently and view safety information (obtain traffic information, navigation instructions or entertainment content) through the second vehicle-mounted screen. The driver adapts slowly to the image quality changes of the second vehicle-mounted screen. Therefore, it is allowed to switch the image quality for a longer time and determine a longer switching duration. When the congestion degree is small but the bumpiness degree is large when the vehicle is driving, most of the driver's attention is mainly focused on the road. Therefore, a slightly longer switching duration can be allowed. When the congestion degree is large but the bumpiness degree is small when the vehicle is driving, most of the driver's attention is mainly focused on the second vehicle-mounted screen. Therefore, a longer switching duration can be allowed.

[0089] In some embodiments, the method for determining the degree of bumpiness of the driving section includes: the vehicle obtains multiple longitudinal accelerations of the vehicle and multiple rotational speeds of the wheels at multiple moments in a preset time period; the vehicle determines a first standard deviation of the multiple longitudinal accelerations, and determines a second standard deviation of the multiple rotational speeds; the vehicle performs weighted summation of the first standard deviation and the second standard deviation based on a first weight and a second weight to obtain the degree of bumpiness of the driving section, the first weight being used to indicate the degree of contribution of the longitudinal acceleration when determining the degree of bumpiness, and the second weight being used to indicate the degree of contribution of the wheel rotational speed when determining the degree of bumpiness.

[0090] It should be understood that in the above solution, each moment corresponds to a longitudinal acceleration and a rotation speed, which is the rotation speed of a certain wheel at the corresponding moment or the average rotation speed of multiple wheels at the corresponding moment.

[0091] In one possible implementation, the method 200 also includes: when the currently displayed content is not the preset display content, the vehicle switches the picture quality mode of the second vehicle-mounted screen to the first picture quality mode, and displays a first prompt message and a target control in the first display area of ​​the second vehicle-mounted screen, the first prompt message being used to prompt that the picture quality mode of the second vehicle-mounted screen has been coordinated with the first vehicle-mounted screen, and the target control being used to trigger the picture quality mode of the second vehicle-mounted screen to switch from the first picture quality mode back to the original picture quality mode.

[0092] It should be understood that the "first prompt information is used to prompt that the picture quality mode of the second vehicle-mounted screen has been coordinated with the first vehicle-mounted screen" in the above scheme means that when the second vehicle-mounted screen does not display safety information, the picture quality mode of the second vehicle-mounted screen is switched to the first picture quality mode because the picture quality mode of the first vehicle-mounted screen needs to be switched to the first picture quality mode, and the picture quality mode of the second vehicle-mounted screen needs to be consistent with the picture quality mode of the first vehicle-mounted screen.

[0093] In the above technical solution, when the second vehicle-mounted screen does not display the preset display information, the vehicle in the method directly switches the picture quality mode of the second vehicle-mounted screen to the first picture quality mode. This is because when the second vehicle-mounted screen does not display the preset display information, switching the picture quality of the second vehicle-mounted screen will not affect the vehicle user, and can also ensure that the picture quality of the second vehicle-mounted screen is consistent with that of the first vehicle-mounted screen. Furthermore, the first prompt information is displayed in the first display area on the second vehicle-mounted screen, which can remind the vehicle user of the reason why the second vehicle-mounted screen switches the picture quality. In addition, the target control is also displayed on the first display area, which can prevent the vehicle user from being able to restore the picture quality mode when he is dissatisfied with the picture quality mode of the second vehicle-mounted screen.

[0094] In some embodiments, when the currently displayed content is not the preset display content, the vehicle switches the picture quality mode of the second vehicle-mounted screen to the first picture quality mode, including: when the currently displayed content is not the preset display content, the vehicle determines whether the picture quality mode of the second vehicle-mounted screen is the first picture quality mode; when the picture quality mode of the second vehicle-mounted screen is not the first picture quality mode, the vehicle switches the picture quality mode of the second vehicle-mounted screen to the first picture quality mode.

[0095] In one possible implementation, after the vehicle switches the picture quality mode of the second vehicle-mounted screen to the first picture quality mode, the method 200 also includes: the vehicle determines whether the display optimization mode of the second vehicle-mounted screen is in an on state; when the display optimization mode is in an on state, the vehicle controls the display optimization mode to be in an 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 color of the image displayed on the car screen by adjusting the color distribution or color channel of the displayed image to restore the color in the real scene.

[0097] In the above technical solution, after the image quality mode of the second vehicle-mounted screen is switched to the first image quality mode, the method controls the display optimization mode of the second vehicle-mounted screen to be turned off. This can turn off the display optimization mode when there is no need to use the display optimization mode, which can reduce the energy consumption of the vehicle.

[0098] It should be understood that the second vehicle-mounted screen (such as the central control screen) can also serve as the main body for switching picture quality. The following description describes the control process of the picture quality mode of the first vehicle-mounted screen when the second vehicle-mounted screen serves as the main body for switching picture quality.

[0099] In some embodiments, the method 200 also includes: when the picture quality mode of the second vehicle-mounted screen is switched to the first picture quality mode, the vehicle determines whether the picture quality mode of the first vehicle-mounted screen is the first picture quality mode; when the picture quality mode of the first vehicle-mounted screen is not the first picture quality mode, the vehicle switches the picture quality mode of the first vehicle-mounted screen to the first picture quality mode.

[0100] In the above technical solution, when the picture quality mode of the second vehicle-mounted screen is switched to the first picture quality mode, in order to maintain the same picture quality effect between the first vehicle-mounted screen and the second vehicle-mounted screen, the picture quality mode of the first vehicle-mounted screen can be directly switched to the first picture quality mode. This is because the picture quality of the first vehicle-mounted screen is switched and has no impact on the vehicle user.

[0102] For example, Figure 4 As shown, the device 400 includes:

[0104] The switching module 402 is used to maintain the image quality mode of the second vehicle-mounted screen when the current display content is the preset display content, and the preset display content is used to indicate that the first image quality mode is not suitable for the vehicle user corresponding to the second vehicle-mounted screen.

The device 400 also includes: a control module being used to maintain the picture quality mode of the second vehicle screen when the second prompt message is not confirmed.
