[0043] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present invention.

[0044] In order to illustrate the technical solution of the present invention, a specific embodiment is provided below for illustration.

[0045] As people's requirements for intelligent cockpits continue to increase, equipping rear passengers with audio and video screens and using table boards have become a must-have for high-end cars.

[0046] In the related art, the rear cabin is not only used for riding in the traditional sense, but also for working. People spend more and more time working in the car. When the screen is placed on the seat, only one screen is turned on, which cannot display the screen content well for all the passengers in the back row. Multiple screens need to be used at the same time, but because the multiple screens are distributed in different positions of the vehicle (such as the roof, the backrests of the two front seats, etc.), it is difficult to operate. In another scenario, when a child or an elderly person sits on one side of the seat and it is inconvenient to operate the screen, other passengers also need to operate the screen, which is very inconvenient.

[0047] Therefore, the present application discloses a strategy to improve the convenience of operating the screen in the above-mentioned scenario through the linkage control of multiple screens in the vehicle.

[0048] In this application, the proposed multi-screen linkage control method is integrated into the vehicle-mounted host as a program and implemented by the vehicle-mounted host. The vehicle-mounted host acts as an intermediate processing device to perform linkage control of each screen. In addition, the multi-screen linkage control method can also be integrated into a separate controller, which is installed in the vehicle to achieve linkage control of multiple screens. This application does not limit the specific way to implement this strategy.

[0049] Figure 1 is a schematic diagram of the implementation flow of a multi-screen linkage control method provided by an embodiment of the present invention, see Figure 1 As shown, the method includes:

[0050] Step S101, receiving a control instruction sent by a first screen in a vehicle for controlling at least one second screen in the vehicle; wherein the second screen is any screen in the vehicle except the first screen.

[0051] Here, a vehicle is usually equipped with multiple screens, such as an instrument screen, a central control screen, a multimedia screen on the roof, a multimedia screen on the seat back, etc. In this embodiment, the multimedia screen on the roof and the multimedia screens on the seat backs can be linked and controlled to facilitate passengers in the vehicle to use these screens for entertainment and office work. Optionally, when any screen receives a control instruction input by the user, the screen becomes the first screen, and the remaining screens in the vehicle become the second screen.

[0052] Step S102, detecting whether the at least one second screen is in an open state.

[0053] In this embodiment, the execution subject is taken as the vehicle host as an example. For example, when the passenger on the left side of the rear seat of the vehicle inputs a control instruction for the multimedia screen on the right side of the front seat back through the function options in the multimedia screen on the left side of the front seat back, the control instruction is first received by the vehicle host. After receiving the control instruction, the vehicle host first determines whether the multimedia screen on the right side of the front seat back is turned on.

[0054] Step S103: if the at least one second screen is not in an open state, open the at least one second screen.

[0055] In this embodiment, for the unopened second screen, the vehicle-mounted host will first open the unopened second screen, such as transmitting the screen opening instruction to its screen controller, so that the screen controller receives the vehicle-mounted host signal and controls the screen motor to complete the screen opening work.

[0056] Step S104: controlling the at least one second screen according to the control instruction.

[0057] Here, the second screen that is not in an open state automatically wakes up after being opened, and executes the control instruction sent by the first screen.

[0058] It can be seen that in the embodiment of the present invention, the user can input control instructions for other screens through any screen. After receiving the control instruction, the vehicle-mounted host determines whether the screen to be controlled is in an open state, turns on the screen that is not in an open state, and controls the screen to be controlled according to the control instruction. Thus, it is achieved by operating on one screen to complete the linkage control of other screens, which greatly improves the convenience of passengers operating multiple screens in the vehicle. Moreover, in this way, it can solve the problem of screen usage in scenarios such as work reporting, business office, or when children or the elderly are sitting on one side of the seat and it is inconvenient to operate the screen, which greatly increases the convenience of multi-screen operation, meets the needs of various multi-screen usage scenarios, and improves the passenger experience.

[0059] As a possible implementation, at least one second screen includes a seat back screen, which is arranged behind a seat back of a preset seat in the vehicle, and a table is also arranged behind the seat back, and when the table is folded, the seat back screen is covered;

[0060] Detect whether the seat back screen is in the open state, including:

[0061] Check whether the screen power of the table and seat back screen is turned on;

[0062] If the screen power of the table top and the seat back screen are both turned on, it is determined that the seat back screen is in the on state; otherwise, it is determined that the seat back screen is not in the on state.

[0063] Accordingly, if the seat back screen is not in the open state, the seat back screen is opened, including:

[0064] If the table is open and the screen power of the seat back screen is not turned on, directly turn on the screen power of the seat back screen;

[0065] If both the table top and the seat back screen are powered off, open the table top, and at the same time or after opening the table top, turn on the seat back screen power.

[0066] In this embodiment, the seat back screen is arranged on the back side of the seat back, generally on the back side of the two front seats, and is closely attached to the back. At the same time, a table board is also arranged on the back side of the seat back. The table board is foldable and can be used by rear passengers to place items when opened, which is convenient for passengers to dine, study, etc. in the car. At this time, the seat back screen is exposed and users can use the seat back screen. When the table board is closed, it covers the seat back screen, which can protect the screen and does not take up space.

[0067] Therefore, after issuing the command to open the seat back screen, the table is first determined in its state. If it is open, the seat back screen is directly awakened and the desktop is shared; if it is closed, the table is first controlled to open, and the seat back screen is turned on at the same time or after the table is opened. In the solution of turning on the table and screen power at the same time, the opening efficiency can be further improved and time can be saved.

[0068] As a possible implementation, the at least one second screen includes a roof screen, which is mounted on the inner side of the roof of the vehicle through a foldable component, and when the foldable component is folded, the screen of the roof screen faces the roof;

[0069] Detect whether the roof screen is in the open state, including:

[0070] Detect whether the screen power of the foldable component and the roof screen is turned on;

[0071] If the screen power of the foldable component and the roof screen are both turned on, it is determined that the roof screen is in the open state; otherwise, it is determined that the roof screen is not in the open state.

[0072] Correspondingly, if the roof screen is not in the open state, opening the roof screen includes:

[0073] If the foldable component is opened and the screen power of the roof screen is not turned on, directly turn on the screen power of the roof screen;

[0074] If the screen power of both the foldable component and the roof screen is not turned on, open the foldable component, and turn on the screen power of the roof screen at the same time or after opening the foldable component.

[0075] In this embodiment, the roof screen is installed on the inner side of the roof of the vehicle and is foldable. When the folding component is folded, the screen of the roof screen faces the roof, which protects the screen and avoids occupying the space inside the vehicle. Therefore, after issuing the opening instruction of the roof screen, it is first determined whether the roof screen is in the open state. If it is, the roof screen is directly awakened and the desktop is shared; otherwise, the foldable component of the roof screen is first controlled to open, and the screen power of the roof screen is turned on at the same time or after the foldable component is opened. Similarly, in the solution of turning on the foldable component and the screen power at the same time, the opening efficiency can be further improved and time can be saved.

[0076] The above seat back screen and roof screen are only two examples given in this application. The first screen and the second screen can also be other types of screens, such as an instrument screen, a central control screen, a co-pilot screen, etc. This application does not limit this.

[0077] In a specific embodiment, after the vehicle host receives the control instruction, the control instruction may carry the identification of the screen to be controlled. The type of the corresponding screen may be determined based on the identification of the corresponding screen. If the screen is an ordinary central control screen or instrument screen, it is determined whether the screen power is turned on. If the screen power is turned on, the control instruction is directly executed. If the screen power is not turned on, the vehicle host transmits the screen turn-on instruction to the screen controller. The screen controller receives the vehicle host signal, controls the screen motor to complete the screen power-on work, and then executes the control instruction.

[0078] If the corresponding screen is a seat back screen or a roof screen, the vehicle-mounted host can identify the status of the table or foldable component through the corresponding sensor. If the table or foldable component is in a closed state, the sensor will feed back a signal to the vehicle-mounted host, and the vehicle-mounted host will perform an opening operation, such as controlling the table to open through the seat controller; if the table or foldable component is in an open state or the vehicle-mounted host receives the feedback signal that the table or foldable component has completed the opening operation, the screen-on command is passed to the screen controller of the screen to be controlled; the screen controller receives the signal from the vehicle-mounted host, controls the screen motor to complete the screen opening work, and automatically wakes up after the screen is opened, and then executes the control command.

[0079] In this way, this embodiment realizes the function of using any one screen to control the opening and power-on of the table top or foldable components of other screens, making it convenient for users to operate different screens at the same time.

[0080] As a possible implementation manner, the control instruction includes a screen sharing instruction.

[0081] Step S104 of controlling the at least one second screen according to the control instruction includes:

[0082] According to the screen sharing instruction, the at least one second screen is controlled to establish a sharing connection with the first screen, so that the at least one second screen displays the content of the first screen.

[0083] In this embodiment, through the screen sharing connection, the first screen shares its screen display content to other screens, so that the same content can be viewed on multiple screens.

[0084] As a possible implementation manner, the control instruction includes a screen operation instruction.

[0085] Step S104 of controlling the at least one second screen according to the control instruction includes:

[0086] According to the screen operation instruction, the at least one second screen is controlled to establish an operation connection with the first screen, so that the at least one second screen executes the operation instruction received by the first screen.

[0087] In this embodiment, through the screen operation connection, the user can control other screens through the first screen, which is convenient for operating multiple screens at the same time. Exemplarily, the first screen is set with a switch button corresponding to the other screens. The first screen obtains the operation of the user clicking the switch button, and the interface of the other screen pops up, and the user can operate the other screen. The first screen obtains the operation of the user clicking the switch button again, switches back to the interface of the first screen, and displays the content of the first screen.

[0088] This embodiment is based on the above control strategy. In one scenario, the rear screen can also establish a connection with the central control screen to call up address navigation, switch music, etc. for the driver when it is inconvenient for the driver.

[0089] As a possible implementation, the method further includes:

[0090] receiving an adjustment instruction sent by the first screen for adjusting an angle corresponding to at least one second screen;

[0091] According to the angle adjustment instruction, adjust the angle of the corresponding second screen.

[0092] In some embodiments, for some screens with adjustable angles, such as a multimedia screen hanging on the roof, the user can also adjust the angle of the roof screen through the screen on the front seat to facilitate viewing.

[0093] As a possible implementation, the method further includes:

[0094] Receiving a screen closing instruction sent by the first screen and corresponding to closing at least one second screen in an opened state;

[0095] According to the screen closing instruction, the corresponding second screen is controlled to be closed.

[0096] In this embodiment, when the user does not need to use the second screen, the user can also send a screen closing instruction through the first screen to control each second screen to close, so as to facilitate the user to close each second screen.

[0097] In combination with the above, in one embodiment, the interaction of each component in the multi-screen linkage control strategy can be seen in Figure 2 As shown, including:

[0098] (1) The user inputs control instructions through the first screen;

[0099] (2) The vehicle host receives the control command and determines whether the corresponding table top is open through the table top sensor;

[0100] (3) If the table top is not open, control the table top to open through the seat controller;

[0101] (4) The vehicle-mounted host controls the screen power of the second screen to turn on through the screen controller;

[0102] (5) The second screen is powered on and executes the control instructions.

[0103] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.
