Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0031] The following describes the screen brightness adjustment method, device, electronic device and vehicle according to the embodiments of the present disclosure with reference to the accompanying drawings.

[0032] The present disclosure provides a screen control system, method, device, electronic device and vehicle. During the process of automatically adjusting the screen brightness, no manual intervention is required, the efficiency and accuracy of screen brightness adjustment can be improved, and the screen brightness of the car can be adjusted more conveniently and quickly, creating a good driving and riding experience for users.

[0033] like Figure 1 As shown, an embodiment of the present disclosure provides a screen brightness adjustment method, comprising:

[0034] Step 101: determine the screen saver interface of the screen to be adjusted in the screen-off state.

[0035] For the embodiments of the present disclosure, the screen to be adjusted may be a screen whose screen brightness is to be adjusted in the screen-off state. The screen-off state may be a state in which the backlight is normally turned off and the screen is off. The screen-off state means that no content is displayed anymore. If you need to view the content displayed on the screen, you can light up the screen by single-clicking, double-clicking, long pressing or sliding. The screen saver interface may be an interface entered when the screen enters the screen-off state without any touch operation during the screen-off time. The interface may generate backgrounds, patterns, etc., and the screen needs to be unlocked before entering the main interface.

[0036] For the embodiments of the present disclosure, the execution entity may be the vehicle computer system, which may dynamically identify the screen saver interface of the screen to be adjusted, and obtain the brightness curve corresponding to the screen saver interface in real time, determine the target screen brightness value that matches the current ambient brightness value in the brightness curve, and then adjust the screen brightness value of the screen to be adjusted to the target screen brightness value, so that the screen brightness of the screen to be adjusted is always adapted to the ambient brightness.

[0037] Step 102: Obtain a brightness curve corresponding to the screen saver interface, wherein different screen saver interfaces correspond to different brightness curves.

[0038] For the embodiments of the present disclosure, as a possible implementation method, the vehicle system can use the cloud server to obtain the brightness curve corresponding to the screen saver interface; as a possible implementation method, the vehicle system can obtain the brightness curve corresponding to the screen saver interface by itself. In the following embodiments of the present disclosure, the technical solution in the present disclosure is explained by taking the use of the cloud server to obtain the brightness curve as an example, but it does not constitute a specific limitation on the technical solution in the present disclosure. Among them, the cloud server can be a virtual server deployed on a virtualized platform for realizing software and hardware decoupling and providing services to the outside world; the brightness curve is set inside the vehicle system, and the brightness curve can be determined based on the pattern, background color or other image information of the screen saver interface. In the following embodiment steps, the background color of the screen saver interface is used to determine the brightness curve as an example to explain the technical solution in the present disclosure, but it does not constitute a specific limitation on the technical solution in the present disclosure. When the background color of the screen saver interface is different, the corresponding brightness curve is also different. Conversely, when the background color of the screen saver interface is the same, the corresponding brightness curve is also the same. For example, the background color of the screen saver interface is black, and the black background corresponds to brightness curve A. Brightness curve A is a pre-set brightness curve corresponding to the black background. By default, when the background color of the screen saver interface is black, it corresponds to brightness curve A.

[0039] In the disclosed embodiment, after the screen to be adjusted enters the screen saver interface, the screen saver program of the vehicle system will send a corresponding request notification to the cloud server according to the currently displayed screen saver interface. The cloud server receives the request notification and parses the request notification to determine the brightness curve corresponding to the screen saver interface, and sends the brightness curve to the automatic brightness adjustment program of the vehicle system, wherein the request notification is used to request the cloud server to send the brightness curve corresponding to the currently displayed screen saver interface to the vehicle system.

[0040] For the disclosed embodiments, since the brightness curves corresponding to different screen saver interfaces are stored in the cloud server, when a change in the screen saver interface is identified, the brightness curve corresponding to the screen saver interface can be re-acquired. By obtaining the brightness curve corresponding to the screen saver interface in the cloud server, the user does not need to upgrade the Android system later to change the brightness curve, and the user does not need to manually adjust the screen brightness, thereby improving the user experience.

[0041] Step 103: Determine a target screen brightness value that matches the current environment brightness value in the brightness curve.

[0042] For the embodiments of the present disclosure, the target screen brightness value is a brightness value that adapts the screen saver interface to the current ambient light brightness. The greater the ambient light brightness, the greater the brightness value of the target screen. Among them, ambient light is a low-intensity light formed by multiple reflections of light from the surrounding environment surface. Ambient light can be used to describe the brightness of an area. Usually, ambient light can be represented by a constant.

[0043] In the disclosed embodiment, the brightness curve corresponding to the screen saver interface sent by the cloud server can be used to determine the target screen brightness value that the screen saver interface can achieve under the current ambient light.

[0044] Step 104: adjust the screen brightness of the screen to be adjusted to the target screen brightness value.

[0045] For the disclosed embodiment, the screen brightness is the screen brightness value of the screen to be adjusted when the screen brightness is not adjusted after entering the screen saver interface; the vehicle system adjusts the screen brightness of the screen to be adjusted to the target screen brightness value calculated in step 103.

[0046] In summary, according to the screen brightness adjustment method, device, electronic device and vehicle provided by the present disclosure, compared with the prior art, the present application can first determine the screen saver interface of the screen to be adjusted in the screen off state; obtain the brightness curve corresponding to the screen saver interface, wherein different screen saver interfaces correspond to different brightness curves; determine the target screen brightness value that matches the current ambient brightness value in the brightness curve; and adjust the screen brightness of the screen to be adjusted to the target screen brightness value. Through the scheme of the present disclosure, the corresponding brightness curve can be automatically adapted according to the screen saver interface of the screen to be adjusted, and the screen brightness adapted to the current ambient brightness value can be adjusted in real time based on the brightness curve. The entire process can automatically select the brightness curve adapted to the screen saver interface without manual intervention, which can improve the efficiency and accuracy of screen brightness adjustment, and can more conveniently and quickly adjust the screen brightness of the car, creating a good driving and riding experience for users.

[0047] Further, as a refinement and extension of the above embodiment, in order to fully illustrate the specific implementation process of the method of this embodiment, this embodiment provides the following Figure 2The specific method shown includes:

[0048] Step 201: Obtain screen information of each screen among multiple screens, where the screen information includes configuration information and touch operation information, and determine a screen to be adjusted among the multiple screens based on the screen information.

[0049] The configuration information may include the screen off time, which can be the system preset screen off time. For example, if the screen off time is set to 2 minutes, the screen will automatically turn off after 2 minutes. The screen off time can also be determined based on the user's usage habits, for example, by counting the user's click frequency or browsing time on a page. The touch operation information may include the cumulative time of the user's non-touch operation. The touch operation may include: single click, double click, long press or slide on the screen.

[0050] For the disclosed embodiment, after obtaining the user touch operation information, the user touch operation information can be matched with the configuration information of the corresponding screen, and the screen to be adjusted for screen brightness adjustment can be determined according to the matching result. Specifically, among multiple screens, a screen with a screen off time equal to the cumulative time is selected in real time as the screen to be adjusted, wherein the cumulative time is the user's touch time on the screen as the starting point, and if the user has no touch operation afterwards, the cumulative time starts counting, and the touch time is the moment when the touch operation is detected. For example, the screen off time of screen A is set to 3 minutes. If it is detected that a touch operation is performed on screen A at 13:00, the touch time of the user's touch operation is recorded as 13:00. If the user has no touch operation afterwards, the timing starts. When the touch time of the user's touch operation (13:00) and the cumulative time without touch operation at the current time (such as 13:03) are equal to the screen off time (3 minutes), screen A is further determined as the screen to be controlled. By comparing the screen off time of each of the multiple screens and the cumulative time since the user has no touch operation, the screen whose screen brightness is to be adjusted in the screen off state can be accurately determined, so that the screen brightness of the screen can be adaptively adjusted in a targeted manner to adapt its screen brightness to the ambient brightness, thereby improving the user's driving experience.

[0051] Step 202: Determine the screen saver interface of the screen to be adjusted in the screen-off state.

[0052] In specific application scenarios, smart cars are equipped with multiple screens. When the screen is off, the screen will display the screen saver interface. After connecting to the Internet, the car system will continuously push and update the screen saver interface in the resource library. As a possible method, users can independently select the desired screen saver interface, or automatically match the screen saver interface according to time, ambient light, etc.

[0053] For the embodiments of the present disclosure, as a possible implementation method, the screen saver interface of the screen to be adjusted in the screen-off state is determined, and the specific implementation process can be described as: determining the vehicle driving characteristics, the vehicle driving characteristics include the in-vehicle environment characteristics and / or the vehicle driving time characteristics; selecting the screen saver interface based on the vehicle driving characteristics, and determining the screen saver interface of the screen to be adjusted in the screen-off state, wherein the vehicle driving characteristics are used to reflect the in-vehicle environment and the vehicle driving time. During vehicle driving, due to the complex and changeable ambient light, different screen saver interfaces produce different colors under different ambient lights and at different vehicle driving times. By determining the screen saver interface and its corresponding color, the brightness corresponding to the current environment and its screen saver interface color can be adjusted, and the user's comfort in the process of looking at the screen saver interface can be ensured.

[0054] For the embodiment of the present disclosure, the specific implementation process of determining the vehicle driving characteristics can be described as: obtaining the vehicle driving state information, the vehicle driving state information includes at least one of the in-vehicle environment information and the vehicle driving time information; inputting the vehicle driving state information into the trained feature recognition model for feature extraction to obtain the vehicle driving characteristics, wherein the in-vehicle environment information may include the in-vehicle environment temperature, the in-vehicle environment light, etc.; the vehicle driving time information may include the current date and its corresponding key festivals (such as the passenger's birthday, the Spring Festival, the National Day, etc.). In a specific application scenario, the in-vehicle environment information and the vehicle driving time information can be dynamically obtained through an environmental perception system, such as a driving recorder, a camera, a sensor, etc. Among them, the feature recognition model can be any computing model that can realize the vehicle driving state recognition function, such as a neural network model, a deep learning model, etc. Exemplarily, the feature recognition model in the present disclosure can be selected as a hidden Markov model, a conditional random field, and a neural network model, etc., which are not specifically limited here.

[0055] For the disclosed embodiment, the screen saver interface is selected based on the vehicle driving characteristics, and the screen saver interface of the screen to be adjusted in the screen-off state is determined. As a possible implementation method, the specific implementation process can be described as: inputting the vehicle driving characteristics into the screen saver prediction model to obtain the first prediction score of the vehicle driving characteristics corresponding to different preset screen saver interfaces; and using the preset screen saver interface with the highest first prediction score as the screen saver interface of the screen to be adjusted in the screen-off state. The screen saver prediction model is used to calculate the first prediction score of the vehicle driving characteristics corresponding to different preset screen saver interfaces.

[0056] In specific application scenarios, different in-vehicle environment information and vehicle driving time information can correspond to a variety of different preset screen saver interfaces, as well as a first predicted score corresponding to each preset screen saver interface, wherein the preset screen saver interface is a pre-set screen saver interface resource library that can be connected to the Internet and continuously updated, which can be adjusted according to actual conditions. The first predicted scores are sorted in order from high to low, and the preset screen saver interface with the highest first predicted score is selected as the screen saver interface for the screen to be adjusted in the screen-off state. The screen saver interface that matches the user's current environment can be accurately selected, which can meet the user's personalized setting requirements for the screen saver interface and improve the user's viewing comfort of the screen saver interface.

[0057] For the disclosed embodiment, the screen saver interface is selected based on the vehicle driving characteristics, and the screen saver interface of the screen to be adjusted in the screen-off state is determined. As a possible implementation method, the specific implementation process can be described as: inputting the vehicle driving characteristics into the screen saver prediction model to obtain the second prediction score of the vehicle driving characteristics corresponding to different preset screen saver interface types; and selecting the screen saver interface of the screen to be adjusted in the screen-off state from at least one preset screen saver interface under the preset screen saver interface type with the highest second prediction score. The screen saver prediction model is used to calculate the second prediction score of the vehicle driving characteristics corresponding to different preset screen saver interface types.

[0058] In specific application scenarios, different in-vehicle environment information and vehicle driving time information can correspond to a variety of different preset screen saver interface types, as well as a second prediction score corresponding to each preset screen saver interface type, wherein different preset screen saver interface types can include a variety of corresponding types of preset screen saver interfaces, and the second prediction scores are sorted in order from high to low. By selecting at least one preset screen saver interface under the preset screen saver interface type with the highest second prediction score as the screen saver interface for the screen to be adjusted in the screen off state, you can choose to automatically replace the preset screen saver interface of the same type. By automatically changing and adjusting the preset screen saver interface, you can prevent damage to the screen to be adjusted due to long-term static screen saver interface, thereby extending the service life of the screen to be adjusted.

[0059] Step 203: Obtain a brightness curve corresponding to the screen saver interface, wherein different screen saver interfaces correspond to different brightness curves.

[0060] For the implementation process of the embodiment of the present disclosure, please refer to the relevant description in step 102 of the embodiment, which will not be repeated here.

[0061] Step 204: Determine a target screen brightness value that matches the current environment brightness value in the brightness curve.

[0062] For the embodiments of the present disclosure, before determining the target screen brightness value that matches the current ambient brightness value in the brightness curve, it may include: using a light sensor or the like to dynamically and in real time obtain the current ambient brightness value of the environment in which the screen to be adjusted is located, wherein the ambient brightness value can be used to describe the brightness of the ambient light in the vehicle, and the higher the brightness of the ambient light, the greater the ambient brightness value; the automatic brightness adjustment program of the vehicle system can determine the target screen brightness value that matches the current ambient brightness value in the brightness curve, and the specific implementation process can be described as: searching for a brightness point with the current ambient brightness value as the X-axis coordinate in the brightness curve, and determining the Y-axis coordinate corresponding to the brightness point as the target screen brightness value, wherein the brightness curve is used to characterize the positive linear relationship between the ambient brightness value and the screen brightness value, so that the screen brightness adjustment can be adjusted according to the current ambient brightness value, that is, the larger the current ambient brightness value, the higher the screen brightness value.

[0063] Step 205: adjust the screen brightness of the screen to be adjusted to the target screen brightness value.

[0064] For the implementation process of the embodiment of the present disclosure, please refer to the relevant description in step 104 of the embodiment, which will not be repeated here.

[0065] In the embodiments of the present disclosure, Figure 3 As shown, for example, there are three screens in the car, among which the secondary screen and the rear screen will enter the screen saver interface (screen saver interface) when no one touches them for more than 10 minutes, which is similar to the screen saver function of a computer when it times out. Because the ambient light on the road is complex and changeable, different screen saver interfaces (screen saver interfaces) have different colors, and corresponding appropriate brightness is required to make the user look comfortable in the car. When entering the screen saver interface (screen saver interface), the screen saver program will send a request notification to the cloud server, and the request notification is used to request the corresponding brightness curve from the cloud server according to the currently displayed screen saver interface (screen saver interface). After receiving the request notification, the cloud server will parse it and send the brightness curve corresponding to the screen saver interface (screen saver interface) to the car system (Android device). The automatic brightness adjustment program (brightness service) of the car system (Android device) will calculate the brightness value of the current interface according to the current ambient light and the brightness curve, and send the brightness value of the current interface to the car screen. The car screen will adjust the current screen brightness value to the calculated brightness value to achieve the effect that the screen saver interface (screen saver interface) looks comfortable under different ambient light.

[0066] In summary, according to the screen brightness adjustment method, device, electronic device and vehicle provided by the present disclosure, compared with the prior art, the present application can first determine the screen saver interface of the screen to be adjusted in the screen off state; obtain the brightness curve corresponding to the screen saver interface, wherein different screen saver interfaces correspond to different brightness curves; determine the target screen brightness value that matches the current ambient brightness value in the brightness curve; and adjust the screen brightness of the screen to be adjusted to the target screen brightness value. Through the scheme of the present disclosure, the corresponding brightness curve can be automatically adapted according to the screen saver interface of the screen to be adjusted, and the screen brightness adapted to the current ambient brightness value can be adjusted in real time based on the brightness curve. The entire process can automatically select the brightness curve adapted to the screen saver interface without manual intervention, which can improve the efficiency and accuracy of screen brightness adjustment, and can more conveniently and quickly adjust the screen brightness of the car, creating a good driving and riding experience for users.
