Description

Technical Field

[0001] This application relates to the field of automotive technology, and more specifically, to a method, device, and vehicle for controlling an in-vehicle screen. Background Technology

[0002] With the development of automotive intelligence, smart cockpits are increasingly equipped with a variety of entertainment facilities to meet passengers' entertainment needs. Besides the central control display screen, in-vehicle screens are common entertainment features, such as ceiling-mounted screens, sunroof displays, and rear-seat entertainment screens. In-vehicle screens offer high-definition picture quality, multi-functionality, and intelligent control, making them suitable for various application scenarios. For example, in business settings, in-vehicle screens can provide business professionals with an efficient and convenient meeting experience; during long journeys, rear passengers can watch videos on in-vehicle screens, providing a wealth of entertainment options.

[0003] However, considering driving safety, in-vehicle screens are usually installed behind the driver's seat, which limits the viewing range of the screen, allowing normal viewing only in the rear passenger area. Therefore, how to expand the viewing range of in-vehicle screens has become an urgent problem to be solved. Summary of the Invention

[0004] In view of the above problems, this application provides a vehicle-mounted screen control method, device, and vehicle to expand the viewing range of the vehicle-mounted screen. The specific solution is as follows:

[0005] The first aspect of this application provides a vehicle screen control method, applied to a controller for controlling a vehicle screen, wherein the vehicle screen is a double-sided display screen installed between the front and rear seats of a vehicle, and the vehicle screen control method includes:

[0006] The system receives control commands from the first screen of the vehicle-mounted screen. The control commands are generated after receiving a preset trigger signal. The preset trigger signal type includes at least: a front seat rotation signal. The first screen is the screen of the vehicle-mounted screen that faces the front seat.

[0007] The type of control command is determined based on the preset trigger signal type;

[0008] In response to the type of the control command, perform the operation corresponding to the type of the control command.

[0009] In one possible implementation, receiving control commands for the first screen of the vehicle-mounted screen includes:

[0010] Receives a first preset trigger signal containing a front seat rotation signal;

[0011] Based on the first preset trigger signal, a first control command is generated to control the startup of the first screen;

[0012] Within a preset time after receiving the first preset trigger signal, it is detected whether a second preset trigger signal containing a signal indicating that the user of the front seat has a viewing need is received.

[0013] If the second preset trigger signal is received, a second control command is generated to control the display of the first screen, and the second control command is determined as the control command;

[0014] If the second preset trigger signal is not received, the first control command is determined to be the control command.

[0015] In one possible implementation, the signal indicating that the user of the front seat has a viewing need includes at least: a voice signal for controlling the display of the first screen, a visual signal that the user of the front seat's eye gaze is on the first screen, a gesture signal that the user of the front seat points to the first screen, and a touch screen signal that the user of the front seat touches the first screen.

[0016] In one possible implementation, determining the type of the control command based on the preset trigger signal type includes:

[0017] When the preset trigger signal type includes the front seat rotation signal and a signal indicating that the user of the front seat has a viewing need, the type of the control command is determined to be: screen display command;

[0018] If the preset trigger signal type includes the front seat rotation signal, the type of the control command is determined to be: screen start command.

[0019] In one possible implementation, the step of performing an operation corresponding to the type of the control instruction in response to the type of the control instruction includes:

[0020] When the type of the control instruction is the screen start instruction, the first screen is started, and the first screen is put into a screen-off state.

[0021] When the type of the control instruction is the screen display instruction, the target display content of the first screen is obtained, and the first screen is controlled to start and display the target display content.

[0022] In one possible implementation, obtaining the target display content of the first screen includes:

[0023] Determine the display status of the second screen of the vehicle screen, wherein the second screen is the screen of the vehicle screen facing the rear seat;

[0024] When the display state of the second screen of the vehicle screen is in the off state, the preset startup screen of the vehicle screen is obtained and the preset startup screen is used as the target display content;

[0025] When the display state of the second screen of the vehicle screen is on, the display content of the second screen is obtained;

[0026] Identify the content type of the displayed content on the second screen;

[0027] Based on the content type and the preset synchronous display type, determine whether the displayed content needs to be displayed synchronously;

[0028] If the displayed content needs to be displayed synchronously, then the displayed content is determined as the target displayed content;

[0029] If the displayed content does not need to be displayed synchronously, the preset initial display screen of the vehicle screen is obtained, and the preset initial display screen is used as the target display content.

[0030] One possible implementation also includes:

[0031] If either the first or second screen of the vehicle-mounted screen fails to display properly, adjust the angle of the vehicle-mounted screen so that the screen that can display properly faces the rear seat.

[0032] One possible implementation also includes:

[0033] If either the first or second screen of the vehicle screen fails to display normally and the control command is received, the screen that can display normally in the vehicle screen will output a prompt message, which will ask the user in the vehicle whether to adjust the angle of the vehicle screen.

[0034] In response to receiving a reply from the user inside the vehicle to the prompt message, if the reply message includes adjusting the target adjustment angle of the in-vehicle screen, the in-vehicle screen is controlled to rotate to the target adjustment angle.

[0035] One possible implementation also includes:

[0036] If either the first screen or the second screen of the vehicle screen fails to display normally, and control commands corresponding to the first screen and the second screen are received respectively, the preset priorities corresponding to the front seats and the rear seats are obtained.

[0037] The seat with higher priority is identified, and the display angle of the screen that can be displayed normally in the vehicle screen is adjusted so that the front of the screen that can be displayed normally faces the seat with higher priority.

[0038] A second aspect of this application provides a vehicle-mounted screen control device, which is used to control a vehicle-mounted screen, wherein the vehicle-mounted screen is a double-sided display screen installed between the front and rear seats of a vehicle, and the vehicle-mounted screen control device includes:

[0039] The instruction receiving unit is used to receive control instructions for the first screen of the vehicle screen. The control instructions are generated after receiving a preset trigger signal. The preset trigger signal type includes at least: a front seat rotation signal. The first screen is the screen of the vehicle screen facing the front seat.

[0040] The instruction type determination unit is used to determine the type of the control instruction based on the preset trigger signal type;

[0041] An instruction response unit is used to perform an operation corresponding to the type of the control instruction in response to the type of the control instruction.

[0042] A third aspect of this application provides a vehicle, including: an in-vehicle screen and a controller for controlling the in-vehicle screen;

[0043] The in-vehicle screen is a double-sided display screen installed between the front and rear seats of the vehicle.

[0044] The controller is used to implement the vehicle screen control method.

[0045] As can be seen from the above technical solutions, the vehicle screen control method, device, and vehicle provided in this application embodiment include a vehicle screen capable of double-sided display installed between the front and rear seats. Since the rear users of the vehicle screen can view the screen from the front, while the front users need to rotate the front seats to view the first screen, this application embodiment uses the front seat rotation signal as a preset trigger signal indicating that the front users have a viewing need for the vehicle screen. Furthermore, according to the type of control instruction determined by the preset trigger signal type, the corresponding operation is performed on the vehicle screen so that the first screen of the vehicle screen meets the needs of the front users.

[0046] This application expands the viewing area of ​​the in-vehicle screen by improving its display type and installation location. Simultaneously, by combining the rotation of the front seats and the types of control commands, it accurately identifies the viewing needs of the front-seat users and executes corresponding operations on both sides of the in-vehicle screen, thereby improving the accuracy of the in-vehicle screen's responsiveness.

[0053] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0054] In this embodiment, the in-vehicle screen, or in-vehicle entertainment screen, refers to any display screen installed in a vehicle, other than those related to driving such as the central control display and head-up display, primarily used for in-vehicle passenger entertainment and work, such as the passenger side screen and rear seat entertainment screens. In-vehicle screens provide in-vehicle users with a wealth of entertainment content and also enable in-vehicle connectivity and social interaction, meeting the entertainment needs of passengers during their journey.

[0055] To meet the entertainment needs of more passengers without affecting the driver's safe driving, in-vehicle screens are usually installed behind the driver's seat. However, this will affect the normal viewing experience for passengers in the front seats. (See reference) Figure 1This application provides a schematic diagram of a vehicle structure, in which an in-vehicle screen is installed between the front and rear seats. The front seats cannot view the content displayed on the screen, and the viewing range is limited. To solve this problem, existing vehicle models typically equip each seat with an in-vehicle screen, which can display content independently or synchronously, meeting the viewing needs of each seat user.

[0056] However, the more in-vehicle screens there are, the higher the vehicle manufacturing cost. This application, while minimizing vehicle manufacturing costs, proposes a vehicle design to expand the viewing area of ​​the in-vehicle screens, referring to... Figure 1 The vehicle includes: an in-vehicle screen and a controller for controlling the in-vehicle screen. The in-vehicle screen is a double-sided display screen installed between the front and rear seats of the vehicle. The double-sided display screen is a first screen and a second screen. The first screen is the screen of the in-vehicle screen facing the front seats, and the second screen is the screen of the in-vehicle screen facing the rear seats.

[0057] Specifically, the in-vehicle screen can be installed on the roof as a ceiling-mounted screen, or on the back of the front seats. When the user wants to view it, the folding structure between the screen and the seat can be manually unfolded to move the screen between the front and rear seats.

[0058] Reference Figure 2 This application provides a flowchart illustrating a method for controlling an in-vehicle screen. The method is applied to a controller to control the in-vehicle screen, enabling it to respond to the viewing needs of front-seat users. Specifically, the process may include:

[0059] Step S110: Receive control instructions from the first screen of the vehicle-mounted screen. The control instructions are generated after receiving a preset trigger signal.

[0060] Step S120: Determine the type of control command based on the preset trigger signal type.

[0061] Step S130: In response to the type of control instruction, perform the operation corresponding to the type of control instruction.

[0062] Among them, the preset trigger signal types include at least: front seat rotation signal.

[0063] It is understandable that rear-seat passengers can operate the second screen from the front. When the vehicle's infotainment system is activated or a rear passenger is detected, the second screen remains constantly displayed, directly responding to voice, facial, gesture, and touch controls from rear-seat passengers, displaying corresponding entertainment content for them to watch. When there are no rear-seat passengers or they do not require viewing the content, the second screen remains off or switched off, displaying no content to achieve energy savings. Therefore, this application does not impose excessive limitations on the control flow of the second screen, and its usage can refer to the traditional usage of in-vehicle screens.

[0064] Reference Figure 1 Since the front seats face the front of the vehicle and cannot view the first screen, this embodiment assumes that the front seat user does not need to view it. If the first screen were displayed using the same method as the second screen described above, it might remain constantly displayed even when the front seat user does not need to view it, increasing vehicle power consumption and potentially affecting the driver's visibility at night. Therefore, in this embodiment, the first screen is typically in an off or closed state until a viewing need is detected in the front seat user, at which point the first screen is illuminated and made displayable.

[0065] Currently, car seats can rotate 360°. Therefore, to allow front-seat users to view the first screen without twisting their bodies, the seats in this embodiment are designed to be rotatable. If a front-seat user wants to view the first screen, they need to rotate the front seat by a certain angle so that the screen is within their field of vision. Based on this, as soon as the controller receives a preset trigger signal indicating that the user is rotating the front seat, it proves that the user may have a viewing need, and generates a control command corresponding to the preset trigger signal to control the display of the first screen.

[0066] It's understandable that when a front-seat user rotates their seat to face the rear passengers, it might be because they want to have face-to-face communication with the rear passengers, and they don't necessarily need to view the main screen. Therefore, the signal of the front seat rotation can be considered a trigger signal, rather than a signal explicitly expressing a viewing need. In this case, a control command corresponding to the preset trigger signal is generated to prevent the main screen from displaying any content. If the preset trigger signal also includes a signal that explicitly expresses the front-seat user's viewing need, then a corresponding control command can be generated to turn on the main screen and display the corresponding content.

[0067] Therefore, the embodiments of this application need to determine the type of the generated control command based on the type of the preset trigger signal. For example, if the type of the preset trigger signal includes: a front seat rotation signal and a voice signal indicating that the vehicle screen is rotating, then the type of the generated control command is an instruction to control the rotation of the vehicle screen. When the type of the preset trigger signal includes: a front seat rotation signal and a voice signal indicating that the user wants to view the first screen, the type of the generated control command can be an instruction to control the content displayed on the first screen. Based on this, the accuracy of display control of the first screen can be improved.

[0068] Furthermore, in response to the type of control instruction determined in the above steps, the operation corresponding to the type of control instruction is executed. In one possible implementation, a corresponding operation flow is pre-defined for each type of control instruction. In response to the type of the received control instruction, the corresponding operation flow is matched, and each step in the operation flow is executed to achieve the screen effect required by the control instruction.

[0069] For example, if the control instruction is a control instruction for displaying the first screen, then the operation flow for controlling the display of the first screen is matched. The operation flow may include, for example, obtaining the preset display screen of the first screen, or controlling the first screen and the second screen to display the same screen content synchronously.

[0070] In summary, by installing a dual-screen display between the front and rear seats of a vehicle, rear passengers can view the screen directly, while front passengers need to rotate their seats to view the first screen. Therefore, this embodiment uses the front seat rotation signal as a preset trigger signal indicating that the front passenger has a viewing need for the screen. Furthermore, based on the type of control command determined by the preset trigger signal, corresponding operations are performed on the screen to ensure that the first screen meets the needs of the front passenger.

[0071] This application expands the viewing area of ​​the in-vehicle screen by improving its display type and installation location. Simultaneously, by combining the rotation of the front seats and the types of control commands, it accurately identifies the viewing needs of the front-seat users and executes corresponding operations on both sides of the in-vehicle screen, thereby improving the accuracy of the in-vehicle screen's responsiveness.

[0072] Next, other possible implementations of the embodiments of this application will be described to refine the embodiments of this application.

[0073] In one possible implementation, receiving the control command for the first screen of the vehicle-mounted screen includes: receiving a first preset trigger signal containing a front seat rotation signal; generating a first control command to start the first screen based on the first preset trigger signal; within a preset time after receiving the first preset trigger signal, detecting whether a second preset trigger signal containing a signal indicating that the user of the front seat has a viewing need is received; if the second preset trigger signal is received, generating a second control command to control the display of the first screen and determining the second control command as the control command; if the second preset trigger signal is not received, determining the first control command as the control command.

[0074] In this embodiment, if the controller only receives a front seat rotation signal, it determines that the front seat has no viewing need. The first screen does not need to respond to the first control command generated corresponding to the first preset trigger signal. The first control command is a command to keep the first screen in a sleep or off state, reducing power consumption when there is no viewing need. Optionally, the first screen responds to the first control command, activating itself and entering a standby state. Once the user in the front seat sends a trigger message clearly indicating a viewing need to the controller again, the controller can promptly respond to the viewing need and display the corresponding content, reducing screen response time.

[0075] If the preset trigger signals received by the controller include a first preset trigger signal of front seat rotation signal and a second preset trigger signal containing a signal indicating that the user of the front seat has a viewing need, it proves that the purpose of the current front seat user rotating the seat is to view the first screen. Therefore, the type of control command generated is a command to control the content displayed on the first screen.

[0076] The signals indicating that the user of the front seat has a viewing need include at least: voice signals for controlling the display on the first screen, visual signals that the user of the front seat's eye gaze is on the first screen, gesture signals that the user of the front seat points to the first screen, and touch screen signals that the user of the front seat touches the first screen.

[0077] Voice signals, visual signals, motion signals, and touch screen signals can be collected by devices such as microphones, cameras, and sensors installed in the vehicle. Optionally, the microphone can be the microphone equipped with the voice assistant configured in the vehicle's intelligent driving system. The cameras and sensors that collect visual signals, motion signals, and touch screen signals may need to be installed on the vehicle screen so that the camera can capture image information of the front-seat user. The touch sensor is installed on the first screen to sense the user's touch operation on the first screen.

[0078] Furthermore, the aforementioned device uploads the collected signals to the controller, which analyzes the received voice and visual signals to determine whether the user's preset trigger signal contains a request to view the first screen. For example, the microphone records the user's voice information and uploads it to the controller, which analyzes the voice information to determine if it contains keywords indicating viewing the first screen after activation. The controller analyzes the user's facial image information captured by the camera to determine if the user's gaze point is on the first screen. If it is, the preset trigger signal is determined to contain a signal indicating viewing the first screen. Optionally, multiple signals can be combined to determine the user's viewing request. For example, combining voice and visual signals, when the user gestures towards the first screen and makes a "open" sound, the controller determines that the current preset trigger signal contains information indicating that the user has a viewing request.

[0079] As can be seen from the above, the preset trigger signal types can include: front seat rotation signals and signals indicating that the user of the front seat has a viewing need. Different preset trigger signal types correspond to different needs. Therefore, based on the preset trigger signal types, the type of control command is determined as follows: when the preset trigger signal type includes front seat rotation signals and signals indicating that the user of the front seat has a viewing need, the type of control command is determined to be: screen display command; when the preset trigger signal type includes front seat rotation signals, the type of control command is determined to be: screen start command.

[0080] Furthermore, in response to the type of control instruction, the operation corresponding to the type of control instruction is performed, including: if the type of control instruction is a screen start instruction, starting the first screen and putting the first screen in a screen-off state; if the type of control instruction is a screen display instruction, obtaining the target display content of the first screen, controlling the first screen to start and display the target display content.

[0081] In this embodiment, the preset trigger signal type only includes the front seat rotation signal, proving that the front-seat user does not have a viewing need. However, when the front-seat user faces the first screen, the probability of the user viewing the first screen increases. To avoid the first screen failing to start in time when the user issues a command to control the display, resulting in excessively long waiting time for the user, this embodiment generates a control command of the screen start type based on the front seat rotation signal. The screen start command means that after the front seat rotates, the first screen is controlled to start, putting it in a screen-off state where it can be turned on at any time, reducing the user's waiting time for the screen to start when the next display is shown.

[0082] If the preset trigger signal includes a signal indicating that the front-seat user has a viewing need, then it can be confirmed that the current front-seat user has a viewing need, and a screen display command to control the display of the first screen can be generated. In one possible implementation, the type of control command can be classified not only according to the type of the preset trigger signal, but also in combination with the signal content in the preset trigger signal indicating that the front-seat user has a viewing need. For example, the screen display command can be subdivided into: commands for synchronous display of the first and second screens, commands for independent display of the first screen, commands for displaying a specific image on the first screen, etc. When a preset trigger signal indicating that the user wants to watch the same video as the user in the rear seat is collected, the type of the generated control signal is a command for synchronous display of the first and second screens.

[0083] In this embodiment, the screen display command corresponds to the following operations: First, the content to be displayed on the first screen is obtained according to the control command. For example, if the control command is an instruction for the first screen and the second screen to display synchronously, then the content currently displayed on the second screen is obtained as the target display content. Further, the obtained target display content is sent to the first screen for display.

[0084] In one possible implementation, obtaining the target display content of the first screen includes: determining the display state of the second screen of the vehicle screen, wherein the second screen is the screen facing the rear seats; if the second screen of the vehicle screen is in a screen-off state, obtaining the preset startup screen of the vehicle screen and using the preset startup screen as the target display content; if the second screen of the vehicle screen is in a screen-on state, obtaining the display content of the second screen; identifying the content type of the display content of the second screen; determining whether the display content needs to be displayed synchronously based on the content type and a preset synchronous display type; if the display content needs to be displayed synchronously, then determining the display content as the target display content; if the display content does not need to be displayed synchronously, then obtaining the preset initial display screen of the vehicle screen and using the preset initial display screen as the target display content.

[0085] In this embodiment, the content displayed on the second screen is acquired first. The type of content is used to determine if there is a need for different displays on both screens. The types of content that need to be displayed synchronously can be freely set according to the user's viewing habits. For example, in an office setting, if the second screen displays a video conference and the front-row user rotates to view the first screen, it is assumed that the front-row user wants to join the video conference, and therefore the video conference is considered the content type that needs to be displayed synchronously. In an entertainment setting, the front-row user may have different entertainment needs from the back-row user when turning around to view the first screen. In this scenario, videos and images displayed on the second screen are considered content types that do not need to be displayed synchronously. Optionally, the content can be categorized based on the platform to which the content displayed on the second screen belongs. For example, if the video displayed on the second screen belongs to a short video platform, then the video is considered not to be a content type that needs to be displayed synchronously.

[0086] Furthermore, if it is determined that the content displayed on the second screen is the type of content that needs to be displayed synchronously, the content displayed on the second screen is taken as the target display content and sent to the first screen, so that the first screen displays the target display content.

[0087] Understandably, if the second screen does not display any valid content or is closed, the preset display screen will be used as the target content. The preset display screen can be the default screen displayed after the second screen is opened, such as a page displaying multiple function icons, a preset browsing page, etc. Valid content refers to the content displayed after the second screen is opened and after secondary operation. (See reference...) Figure 3 The example diagrams provided in this application embodiment illustrate the display content. Image a shows the initial display screen after the second screen is opened. The initial display screen includes multiple function icons or application software icons, such as a video player, music player, navigation, video conferencing, and folder, as shown. The user in the back row selects any function icon in the initial display screen, and the content corresponding to the selected function icon is displayed. In this application embodiment, this "selection operation" is a secondary operation on the second screen. For example, refer to... Figure 3 In image a, the user sends a voice command to the controller to "start a video conference." This voice command can be seen as a secondary operation on the second screen. The controller responds to the command by displaying the corresponding video conference content on the second screen. Figure 3 Image b in the text.

[0088] This can be understood as follows: as long as the content displayed on the second screen is not the initial display screen, the displayed content can be considered valid content. This is because even if the first screen is not displayed synchronously with the second screen, the same preset display screen is displayed first when the first screen is opened. Figure 3For image 'a' in the sequence, no additional synchronization step is required.

[0089] In one possible implementation, the vehicle screen control method implemented by the controller in this application embodiment further includes: adjusting the angle of the vehicle screen so that the screen that can be displayed normally faces the rear seat when either the first screen or the second screen of the vehicle screen cannot be displayed normally.

[0090] When either side of the dual-screen display in a vehicle becomes black, displays a distorted image, freezes, or is damaged, the user facing that side will be unable to view the screen. In this embodiment, the angle of the vehicle screen can be adjusted so that the screen that can display normally can meet the viewing needs of as many users as possible. In this embodiment, it is assumed that the number of viewers in the rear seats is greater than that in the front seats; therefore, the front of the screen that can display normally is turned towards the rear seats for viewing by rear seat users.

[0091] In another possible implementation, if either the first or second screen of the vehicle screen fails to display properly and a control command is received, the screen that can display properly in the vehicle screen is controlled to output a prompt message asking the user in the vehicle whether to adjust the angle of the vehicle screen; in response to receiving a reply message from the user in the vehicle to the prompt message, if the reply message includes adjusting the target adjustment angle of the vehicle screen, the vehicle screen is controlled to rotate to the target adjustment angle.

[0092] It is understandable that users' preferences often differ from the program's default settings. To avoid the in-vehicle screen simply adjusting its angle according to the default settings, thus preventing users who genuinely need the screen from viewing it, this application embodiment solicits users' opinions on angle adjustments by sending a prompt message, ensuring that users who genuinely need the screen can view it.

[0093] For example, if only the first screen of the in-vehicle display can function normally, the first screen can ask the user questions such as "Do you want to turn the first screen towards the rear seats?" or "How much should I rotate the first screen?" via pop-up windows or voice prompts. At the same time, the system can collect the user's voice information within a preset time after the question is asked, use this voice information as the user's answer to the question, further analyze the voice information to extract the target adjustment angle for the first screen, or display multiple adjustment angle options on the first screen to solicit the user's adjustment needs for the screen that can display normally through various means, and adjust the orientation angle of the screen that can display normally based on the user's feedback.

[0094] In another possible implementation, if either the first or second screen of the vehicle screen fails to display properly and control commands corresponding to the first and second screens are received respectively, the priorities corresponding to the front and rear seats are obtained in advance; the seat with higher priority is determined, and the display angle of the screen that can display properly in the vehicle screen is adjusted so that the front of the screen that can display properly faces the seat with higher priority.

[0095] The viewing needs of the front and rear seats can also be preset. For example, if the viewing needs of the front seats are higher than those of the rear seats, then when both the front and rear seats receive control commands for the in-vehicle screen, and the control commands are screen display commands, the viewing needs of the front seats with higher priority will be satisfied. Therefore, the display angle of the screen that can be displayed normally in the in-vehicle screen will be adjusted so that the front of the screen that can be displayed normally faces the front seats.

[0096] Therefore, the above-mentioned methods of adjusting the angle of the screen that can be displayed normally in the vehicle screen are all aimed at meeting the viewing needs of users in the vehicle as much as possible when the vehicle screen cannot display normally.

[0097] Next, refer to Figure 4 This application provides another structural diagram of a vehicle, which serves as an example of the practical application of the aforementioned vehicle screen control method. The vehicle has two rows of seats, a common sedan seating layout. The vehicle screen is a ceiling-mounted screen capable of double-sided display, installed between the front and rear seats, without obstructing the driver's view. The front seats include a driver's seat and a front passenger seat. The front passenger seat can rotate 180° to face the rear passenger, with the passenger facing the first screen of the ceiling-mounted screen, which is the screen facing the front passenger seat.

[0098] When the passenger seat rotates 180°, it sends a rotation signal to the controller. Upon receiving the rotation signal, the controller also detects whether the user inside the vehicle is explicitly signaling to view the first screen. For example, if the passenger double-clicks the first screen, the controller generates a control signal corresponding to that signal. This control signal is a screen display instruction for the first screen.

[0099] When the controller detects an anomaly such as a distorted or black screen on the first screen of the ceiling-mounted display, and if the second screen is not in use or displaying content at that time, the ceiling-mounted display structure will automatically rotate 180°. This means the first screen will then face the rear passengers, automatically lighting up and responding to their display needs. However, if the first screen is currently in use or displaying content, it indicates that the front passengers may be viewing or displaying specific information on it. In this case, both front and rear passengers have display needs, and there is no priority in this example because it's impossible to determine whose needs are more urgent. Therefore, the controller will prompt the first screen or other in-vehicle devices via voice / pop-up to confirm whether rotation is allowed. If the user confirms, rotation will occur automatically. If the user does not agree to rotation, a prompt will appear asking if they want to rotate the screen to a specific angle to allow both front and rear passengers to view the content simultaneously. This maximizes the satisfaction of the in-vehicle users' needs and reduces complaints from rear passengers due to ceiling-mounted screen malfunctions or inability to view content.

[0100] Furthermore, due to the unique installation location of the vehicle-mounted screen in this embodiment—between the front and rear seats, similar to the installation location of a ceiling-mounted screen—the content displayed on the first screen of the vehicle-mounted screen is visible to people outside the vehicle through the windshield. Therefore, when picking up people at a train station or searching for people in other scenarios, the driver or users inside the vehicle can input and display customized content on the vehicle-mounted screen to show relevant information on the first screen of the ceiling-mounted screen, thus achieving the purpose of picking up or finding people. Similarly, the vehicle-mounted screen can also be used for advertising, product display, and other information display.

[0101] In another scenario, when the controller detects information such as vehicle malfunction, accident, or collision, it automatically controls the first screen of the in-vehicle display to alert the driver outside the vehicle or display emergency assistance requests, thanks to the unique installation position of the ceiling-mounted screen. Unlike ordinary exterior or window displays, which are specifically designed for external warnings and are expensive with limited practical applicability, the ceiling-mounted screen integrates external display needs using its unique location and dual-sided screen properties. It can also automatically trigger such functions, making it a novel solution while simultaneously catering to the display needs of users inside the vehicle.

[0102] The following describes a vehicle screen control device provided in an embodiment of this application. The vehicle screen control device described below can be referred to in correspondence with the vehicle screen control method described above.

[0103] First, combined Figure 5 This section introduces the vehicle screen control device, which is used to control the controller of the vehicle screen. Figure 5 As shown, the vehicle-mounted screen control device may include:

[0104] The instruction receiving unit 100 is used to receive control instructions for the first screen of the vehicle screen. The control instructions are generated after receiving a preset trigger signal. The preset trigger signal type includes at least: a front seat rotation signal.

[0107] In summary, by installing a dual-screen display between the front and rear seats of a vehicle, rear passengers can view the screen directly, while front passengers need to rotate their seats to view the first screen. Therefore, this embodiment uses the front seat rotation signal as a preset trigger signal indicating that the front passenger has a viewing need for the screen. Furthermore, based on the type of control command determined by the preset trigger signal, corresponding operations are performed on the screen to ensure that the first screen meets the needs of the front passenger.

[0108] This application expands the viewing area of ​​the in-vehicle screen by improving its display type and installation location. Simultaneously, by combining the rotation of the front seats and the types of control commands, it accurately identifies the viewing needs of the front-seat users and executes corresponding operations on both sides of the in-vehicle screen, thereby improving the accuracy of the in-vehicle screen's responsiveness.

[0127] The synchronization requirement judgment subunit is used to determine whether the display content needs to be displayed synchronously based on the content type and the preset synchronization display type.

[0128] The second sub-unit for determining target display content is used to determine the display content as the target display content if the judgment result of the synchronization requirement judgment sub-unit is yes.

[0129] The second sub-unit for determining the target display content is used to obtain the preset initial display screen of the vehicle screen and use the preset initial display screen as the target display content if the judgment result of the synchronization requirement judgment sub-unit is negative.
