Moreover, even after the screen position changes, the content displayed on the in-vehicle screens remains linked, achieving the goal of still presenting the linked results after the screen position changes.

[0021] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0022] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0023] First, the technical terms appearing in the embodiments of this invention are explained as follows:

[0024] In-Vehicle Infotainment (IVI): An IVI is a comprehensive in-vehicle information processing system that uses a dedicated onboard central processing unit, based on the vehicle's bus system and internet services. IVI can realize a range of applications including 3D navigation, real-time traffic information, driver assistance, fault detection, vehicle information, vehicle control, mobile office, wireless communication, and online entertainment functions, greatly enhancing the vehicle's level of electronic, networked, and intelligent capabilities.

[0025] Feature extraction: Feature extraction is a method of extracting desired features through image analysis and transformation. In machine learning, pattern recognition, and image processing, feature extraction starts with an initial set of measurement data and establishes derived values ​​(features) designed to provide information and avoid redundancy, thereby facilitating subsequent learning and generalization steps and, in some cases, leading to better interpretability. Feature extraction is related to dimensionality reduction. The quality of the features has a crucial impact on generalization ability.

[0026] Example 1

[0027] According to an embodiment of the present invention, an embodiment of a vehicle screen control method is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0028] Optionally, the vehicle screen includes: a main screen with a fixed position and multiple secondary screens with movable positions.

[0029] Figure 1 This is a flowchart of a vehicle screen control method according to an embodiment of the present invention, such as... Figure 1As shown, the method includes the following steps:

[0030] Step S102: Control the main screen to display the first output interface, and control multiple sub-screens to display the second output interface.

[0031] The first and second output interfaces mentioned above are obtained by dividing the preset output interface based on the screen parameters of the vehicle screen. The screen parameters include the number and size of the vehicle screen. The preset output interface includes vehicle functions and interface styles. The vehicle functions can be functions such as forward collision warning, lane departure warning, and traffic sign recognition. The interface style refers to the layout style of the screen display interface and the user's operation style.

[0032] In one alternative embodiment, the main screen can be controlled to display a first output interface, and multiple secondary screens can be controlled to display a second output interface, through a vehicle screen control device.

[0033] In one optional embodiment, a segmentation module algorithm can be used to segment a preset output interface based on the screen parameters of the vehicle screen to obtain a first output interface and a second output interface, which are then distributed by a processor. The vehicle screen control device can control the main screen to display the first output interface and control multiple sub-screens to display the second output interface. Segmenting the preset output interface based on the screen parameters of the vehicle screen to obtain the first and second output interfaces allows for better adaptation of the output interfaces to vehicle screens with different screen parameters, enhancing the flexibility between the screens.

[0034] Step S104: In response to a change in the position of any two sub-screens among the multiple sub-screens, determine the relative position of the multiple sub-screens to the main screen.

[0035] In one alternative embodiment, the position of the secondary screen can be changed by altering its size, manually dragging, or other means.

[0036] In response to a change in the position of any two sub-screens among multiple sub-screens, the relative positions of the multiple sub-screens and the main screen are determined, including: establishing a Cartesian coordinate system on a preset plane where the main screen is located, with the first position of the main screen as the origin; mapping the screen mark of each sub-screen to the preset plane where the main screen is located to obtain the second position of each sub-screen in the preset plane; and determining the relative positions of the multiple sub-screens and the main screen based on the multiple second positions and the first position.

[0037] The above establishes a rectangular coordinate system on the preset plane where the main screen is located, with the first position of the main screen as the origin. Here, the first position refers to the position of the main screen on the preset plane, and the preset plane refers to the plane where the main screen is located. The rectangular coordinate system can be a rectangular coordinate system with the first position of the main screen as the origin, the length of the preset plane as the x-axis, and the width of the preset plane as the y-axis.

[0038] In one optional embodiment, a mark can be made on the screen of each of the multiple sub-screens, and the mark can be mapped to a preset plane where the main screen is located. By observing the x-axis and y-axis coordinates of each mark in the Cartesian coordinate system on the preset plane, the second position (x, y) of each sub-screen in the preset plane can be obtained. The mark can be any form of mark, such as drawing a circle in the center of the screen.

[0039] The aforementioned determination of the relative positions of multiple secondary screens to the main screen based on multiple second and first positions refers to determining the positions of the multiple secondary screens and the main screen in a preset plane after obtaining their positions. The position of the main screen in the preset plane is then used as a reference point to determine the positions of the multiple secondary screens. Each screen has a relative position detection module that can detect the position code of the secondary screen relative to the main screen. When multiple screens change positions, the screen undergoing the change sends its transformed coordinate code to the main screen. The processor's algorithm analyzes the coordinate codes of each screen, and the analysis results are transmitted to the cloud segmentation module via the in-vehicle infotainment system (IVI). This process determines the relative positions of the multiple secondary screens to the main screen.

[0040] Step S106: Based on the relative positions of the multiple sub-screens and the main screen, the second output interfaces of the multiple sub-screens are redistributed to obtain the third output interfaces of the multiple sub-screens.

[0041] Based on the relative positions of multiple secondary screens and the main screen, the second output interfaces of the multiple secondary screens are redistributed to obtain the third output interfaces of the multiple secondary screens. This includes: generating a first segmented window corresponding to each secondary screen on a preset plane based on the second position and screen parameters of each secondary screen; segmenting the preset output interface based on the first segmented window to obtain the first segmented interface corresponding to each secondary screen; obtaining the vehicle function parameters and interface style parameters corresponding to the first segmented interface; and updating the second output interface of each secondary screen based on the vehicle function parameters and interface style parameters to obtain the third output interface.

[0042] In this approach, the shape formed by the borders of each sub-screen is treated as a window, and this window is the first segmentation window.

[0043] In an alternative embodiment, the borders of each sub-screen can be extracted by feature extraction to obtain the first segmentation window.

[0044] The above-mentioned segmentation of the preset output interface based on the first segmentation window to obtain the first segmentation interface corresponding to each sub-screen refers to using the first segmentation window to capture the interface on the preset output interface, and the captured interface is the first segmentation interface.

[0045] In one alternative embodiment, MATLAB can be used to capture the first segmented interface on a preset output interface using a first segmentation window, and the vehicle function parameters and interface style parameters corresponding to the first segmented interface can be obtained.

[0046] The above-mentioned update of the second output interface of each secondary screen based on vehicle function parameters and interface style parameters to obtain the third output interface refers to the process where, after multiple secondary screens change positions, the coordinate codes of the multiple secondary screens after the change are transmitted to the cloud segmentation module via IVI. The segmentation module then reallocates the vehicle function parameters and interface style parameters to each screen according to the vehicle function parameters and interface style parameters obtained in the first segmentation. Each screen automatically converts upon receiving the new vehicle function parameters and interface style parameters. For example, if the screens in the vehicle currently include a central control screen A, a secondary screen B, a rear screen C, and a rear screen D, the segmentation module segments the screens based on the screen parameters and assigns functions and themes 1, 2, 3, and 4, with the corresponding relationships A-1, B-2, C-3, D-4. When B moves to the position of D, D moves to the position of C, and C moves to the position of B, the updated correspondence is A-1, B-4, C-2, D-3 after processing by the detection module, the cloud processor, and the segmentation module. (The above positions are relative to the position of A and do not represent the actual positions).

[0047] The above-mentioned updating of the second output interface of each sub-screen based on vehicle function parameters and interface style parameters includes: obtaining the screen type corresponding to each sub-screen; responding to the screen type being a first preset type, controlling the vehicle function parameters and interface style parameters, and updating the second output interface according to the first preset method; responding to the screen type being a second preset type, controlling the vehicle function parameters and interface style parameters, and updating the second output interface according to the second preset method.

[0048] In one alternative embodiment, the screen type of each sub-screen can be obtained by manually determining the purpose of each sub-screen. The screen type can be office type, entertainment type, etc.

[0049] The above-mentioned response, when the screen type is a first preset type, controls the vehicle function parameters and interface style parameters, and updates the second output interface according to a first preset method; when the screen type is a second preset type, it controls the vehicle function parameters and interface style parameters, and updates the second output interface according to a second preset method. Here, the first preset type and the second preset type refer to two screen types with different uses. The first preset method means updating the second output interface according to the vehicle function parameters and interface style parameters required for the first preset type, and the second preset method means updating the second output interface according to the vehicle function parameters and interface style parameters required for the second preset type. For example, when the screen type is for office use, vehicle functions and interface styles can be filtered first to remove those that might interfere with office work; when the screen type is for entertainment use, the screen can be updated directly using the determined vehicle function parameters and interface style parameters.

[0050] In the above embodiments of the present invention, the method further includes: determining a first distance between the main screen and each sub-screen based on a first position and a second position; obtaining a first control parameter corresponding to the first distance from a preset database based on the first distance, wherein the preset database includes at least a plurality of distance parameters and a plurality of control parameters of the same number, the distance parameters and control parameters are in one-to-one correspondence, and the first control parameter is a parameter used to control vehicle functions and interface style; updating the second output interface based on the first control parameter to obtain a third output interface for each sub-screen.

[0051] In an optional embodiment, the first distance between the main screen and each sub-screen can be determined using the Cartesian coordinate system established in the preset plane. For example, if the coordinates of the main screen are (x1, y1) and the coordinates of a sub-screen are (x2, y2), then the distance between the main screen and this sub-screen is...

[0052] In one alternative embodiment, the first control parameter corresponding to the first distance can be obtained from a preset database based on the first distance by methods such as direct querying, reading data using an application, or reading data after connecting to the database through a tool.

[0053] The aforementioned preset database includes at least a number of distance parameters and multiple control parameters, with each distance parameter and control parameter corresponding to the other. The first control parameter is used to control the vehicle's functions and interface style. It refers to the parameter that, when the positions of multiple sub-screens change, can be directly determined from the preset database based on the relative distance between the main screen and the multiple sub-screens, thereby redistributing the second output interface of the multiple sub-screens in a more efficient way.

[0054] Step S108: Control the main screen to display the first output interface, and control multiple secondary screens to display the third output interface.

[0055] In one alternative embodiment, the main screen can be controlled to display a first output interface, and multiple secondary screens can be controlled to display a third output interface, through a vehicle screen control device.

[0056] In the above embodiments of the present invention, the method further includes: obtaining multiple preset movement ranges corresponding to multiple sub-screens; performing fusion processing on the multiple preset movement ranges to obtain a first fusion region; performing expansion processing on the first fusion region to obtain a first control region, wherein the first control region is used to generate a preset output interface, and the first control region is the outer rectangle of the first fusion region.

[0057] The preset movement range refers to the maximum movement range of the sub-screen within a preset plane; the fusion processing involves combining the movement ranges of each sub-screen into a larger range, which is the first fusion region; the expansion processing involves expanding the first fusion region into a bounding rectangle, where the bounding rectangle is a rectangle that connects to every vertex of the first fusion region. Compared to irregular shapes, rectangles make it easier to arrange parameters and determine their positions within the output interface. Generating the preset output interface in this way can effectively improve efficiency.

[0058] In one alternative embodiment, fusion and extension processing can be performed using Open Source Computer Vision Library (OpenCV). Multiple preset movement ranges corresponding to multiple sub-screens can be determined based on the size of multiple sub-screens and the size of the entire preset plane.

[0059] In the above embodiments of the present invention, the method further includes: obtaining the current driving speed of the vehicle; in response to the driving speed being in a first speed range, generating a preset output interface in a first control region according to a first control parameter; and in response to the driving speed being in a second speed range, generating a preset output interface in the first control region according to a second control parameter.

[0060] The first and second speed ranges can be set by the user according to their driving habits. The first and second control parameters are two different parameters used to control vehicle functions and interface styles according to different speed ranges. For example, when the vehicle speed is [0, 20) km / h, a preset output interface can be generated in a minimalist style; when the vehicle speed is [20, ∞) km / h, a preset output interface can be generated in a punk style, etc. The driving style can be set by the user according to their driving habits.

[0061] In one alternative embodiment, a speed sensor can be used to obtain the vehicle's current speed.

[0062] Figure 2 This is a schematic diagram illustrating a specific process of a vehicle screen control method according to an embodiment of the present invention, as shown below. Figure 2 As shown, the specific process of this method is as follows: When the positions of the secondary screen, rear screen 1, rear screen 2, etc., change, the position detection module calculates the position coordinates relative to the central control screen based on the central control screen, where the central control screen is a stationary screen. Then, the transformed coordinate code is sent to the main screen. The processor's algorithm analyzes the coordinate codes of each screen to determine the relative positions of the multiple secondary screens and the main screen. At the same time, the analysis results, as well as the screen information and quantity of the multiple secondary screens, are transmitted to the cloud controller via IVI. The controller then transmits the information to the segmentation module. Finally, the processor reallocates the vehicle function parameters and interface style parameters according to the vehicle function parameters and interface style parameters obtained from the first segmentation and distributes them to the central control screen, secondary screen, rear screen 1, rear screen 2, etc.

[0063] Through the above steps, the main screen is controlled to display the first output interface, and multiple secondary screens are controlled to display the second output interface. In response to any change in the position of any two secondary screens, the relative position detection module determines the relative positions of the secondary screens with respect to the main screen. Based on the relative positions of the secondary screens with respect to the main screen, and the vehicle infotainment functions and theme results processed by the segmentation module, the second output interfaces of the secondary screens are redistributed to obtain the third output interfaces of the secondary screens. The main screen is then controlled to display the first output interface, and the multiple secondary screens are controlled to display the third output interface. Because the second output interface and the first output interface displayed on the main screen are interconnected, and the third output interface is obtained by redistributing the second output interfaces of the secondary screens based on the relative positions of the secondary screens with respect to the main screen, and the vehicle infotainment functions and interface styles processed by the segmentation module, the content displayed on the in-vehicle screens is interconnected. Moreover, even after the screen positions change, the content displayed on the in-vehicle screens remains interconnected, achieving the goal of maintaining interconnected results even after screen position changes. This realizes the technical effect of automatic conversion of vehicle infotainment functions and themes after each screen position change, thus solving the technical problem that vehicle screens cannot achieve multi-screen interconnection.
