Rear passengers can use armrest screen 501's functions by touching it.

[0084] The overhead screen device 100 is mounted on the top of the vehicle 10000 (roof 2000). The overhead screen 10 can provide a better entertainment experience for rear passengers. For example, the overhead screen 10 can be used to display driving information of the vehicle 10000, navigation maps, or weather forecasts. The overhead screen 10 can also be used to play cartoons, educational programs, and other video materials. The first control instruction is an instruction for controlling the overhead screen 10. The processing module 20 is electrically connected to the overhead screen 10. After receiving the first control instruction, the processing module 20 can control the overhead screen 10 accordingly to put the overhead screen 10 into a target state. For example, after receiving the first control instruction, the processing module 20 can control the overhead screen 10 to rotate, control the overhead screen 10 to perform corresponding functions within a specified time, and control the overhead screen 10 to turn on and off.

[0085] See also Figures 1 to 3In one embodiment, the central control screen 301 is used to input the first control command. In this case, if the overhead screen 10 needs to be controlled, the front passenger can touch the central control screen 301 to input the first control command. After receiving the first control command, the processing module 20 controls the overhead screen 10 according to the first control command, so that the overhead screen 10 is in the target state. In another embodiment, the armrest screen 501 is used to input the first control command. In this case, if the overhead screen 10 needs to be controlled, the rear passenger can touch the armrest screen 501 on the seat 3000 to input the first control command. After receiving the first control command, the processing module 20 controls the overhead screen 10 according to the first control command, so that the overhead screen 10 is in the target state. In another embodiment, both the central control screen 301 and the armrest screen 501 can be used to input the first control command. At this time, both the front and rear passengers can operate the overhead screen 10. The overhead screen device 100 has multiple control methods, making it convenient for passengers to control and adjust the overhead screen device 100. In other embodiments, passengers can also control the overhead screen 10 by touching the user interface of the overhead screen 10 itself.

[0086] In the control method for the overhead screen device 100 according to the embodiment of the present application, a first control command is inputted to the armrest screen 501 or the central control screen 301. After receiving the first control command, the processing module 20 controls the overhead screen 10 according to the first control command. Passengers can control the overhead screen 10 by touching the central control screen 301 or the armrest screen 501. The overhead screen device 100 of the present application has multiple control methods, making it convenient for passengers to control and adjust the overhead screen device 100.

[0087] In some embodiments, 02: controlling the overhead screen device 100 according to the first control instruction includes:

[0088] 021: Control the movement of the overhead screen 10 according to the movement instruction to change the position and / or angle of the overhead screen 10 relative to the roof 2000.

[0089] Please combine Figure 1 and Figure 2 In some embodiments, the first control instruction includes a motion instruction, and the overhead screen 10 is used to input the first control instruction; the processing module 20 is used to control the movement of the overhead screen 10 according to the motion instruction to change the position and / or angle of the overhead screen 10 relative to the roof 2000.

[0090] See also Figure 1 、 Figure 2 and Figure 4Wherein, if the first control instruction is a motion instruction, upon receiving the motion instruction, the processing module 20 can control the movement of the overhead screen 10. Specifically, the processing module 20 can control the rotation of the overhead screen 10 about the connection between the overhead screen 10 and the roof 2000 (hereinafter referred to as the "connection"). Rotation of the overhead screen 10 about the connection can include: the overhead screen 10 flipping up and down relative to the roof 2000 about an axis parallel to the width direction of the vehicle 10000 (i.e., the overhead screen 10 can change the angle between the overhead screen 10 and the roof 2000), and the overhead screen 10 rotating horizontally about the connection within the plane formed by the length and width directions of the vehicle 10000. The movement of the overhead screen 10 can be controlled by the processing module 20, and the movement of the overhead screen 10 can also be achieved by manual control by a passenger.

[0091] In the case where the overhead screen 10 can be flipped up and down relative to the roof 2000, when the overhead screen 10 is not needed, the passenger can input motion instructions through the central control screen 301 and the armrest screen 501. The processing module 20 can control the overhead screen 10 to flip according to the motion instructions so that the overhead screen 10 is aligned with the roof 2000 (i.e., the angle between the overhead screen 10 and the roof 2000 can be approximately 0°). This can prevent passengers from colliding with the overhead screen 10 while moving around in the vehicle, thereby ensuring passenger safety and preventing the overhead screen 10 from snagging on passengers' clothing, backpacks, etc. When the overhead screen 10 is needed, the passenger can input motion instructions through the central control screen 301 and the armrest screen 501. The processing module 20 can control the overhead screen 10 to flip according to the corresponding motion instructions so that the overhead screen 10 is flipped to an angle suitable for the passenger's viewing.

[0092] If the overhead screen 10 can rotate horizontally around its connection, it can adapt to different viewing angles. Passengers can input motion commands via the central control screen 301 or the armrest screen 501. The processing module 20 controls the rotation of the overhead screen 10 based on the motion commands, allowing the screen to rotate to the desired viewing angle. For example, if a passenger is seated near a vehicle door, the overhead screen 10 can rotate horizontally relative to the roof 2000 so that the user interface of the overhead screen 10 faces the passenger, making it easier for the passenger to view the content.

[0093] The passenger inputs motion instructions through the central control screen 301 or the armrest screen 501. After the processing module 20 receives the motion instructions, the processing module 20 can control the overhead screen 10 to move to the target position. The overhead screen 10 can meet the viewing needs of passengers at different angles. The passenger has a better experience when using the overhead screen 10. At the same time, the passenger's control over the overhead screen 10 is also relatively simple.

[0094] See also Figure 1 、 Figure 2 and Figure 5 In some embodiments, 021: controlling the movement of the top screen 10 according to the movement instruction to change the position and / or angle of the top screen 10 relative to the vehicle roof 2000 includes:

[0095] 0211: Get movement instructions;

[0096] 0213: Processing motion commands; and

[0097] 0215: Control the motion mechanism 50 to move according to the processed motion instruction to drive the top screen 10 to move.

[0098] In some embodiments, the top-mounted screen device 100 also has a motion mechanism 50, and the processing module 20 includes a host 30 and a second processor 23. The host 30 is provided with a first processor 21, and the second processor 23 is electrically connected to the first processor 21 and the motion mechanism 50; the first processor 21 is used to obtain motion instructions and process motion instructions; the second processor 23 is used to control the movement of the motion mechanism 50 according to the processed motion instructions to drive the top-mounted screen 10 to move.

[0099] See also Figure 1 、 Figure 2 and Figure 5 , wherein the second processor 23 is connected to the first processor 21 and the motion mechanism 50, and the first processor 21 and the second processor 23 of the present application are both microcontroller units (MCU). After the passenger inputs the motion instruction through the central control screen 301 or the armrest screen 501, the first processor 21 can obtain the motion instruction and process the motion instruction. The first processor 21 processes the motion instruction means that: the signal transmission between the first processor 21 and the second processor 23 is usually a controller area network signal (Controller Area Network, CAN), and the motion instruction obtained by the first processor 21 may be a serial peripheral interface signal (Serial Peripheral Interface, SPI) or an interconnected integrated circuit signal (Inter-Integrated Circuit, I2C). After the first processor 21 obtains the motion instruction of the SPI or I2C signal, the first processor 21 can convert the motion instruction of the SPI or I2C signal into a motion instruction of the CAN signal. The first processor 21 can output the processed motion instructions (motion instructions of the CAN signal) to the second processor 23. After receiving the motion instructions, the second processor 23 can control the motion mechanism 50 to drive the top screen 10 to move, that is, the motion mechanism 50 can drive the top screen 10 to flip up and down relative to the roof 2000 and rotate horizontally around the connection.

[0100] The first processor 21 obtains and processes motion instructions, and the second processor 23 controls the motion mechanism 50 to drive the overhead screen 10 to move according to the motion instructions, so that after the passenger inputs the motion instruction through the central control screen 301 or the armrest screen 501, the overhead screen 10 can effectively rotate to adapt to the different viewing needs of the passengers.

[0101] See also Figure 1 、 Figure 2 and Figure 6 In some embodiments, 0215: controlling the motion mechanism 50 to move according to the processed motion instruction to drive the top screen 10 to move, including:

[0102] 02151: When the current angle is different from the target angle, the motion mechanism 50 is controlled to move according to the processed motion instruction to drive the top screen 10 to rotate to the target angle.

[0103] In some embodiments, the motion instruction carries a target angle, and the overhead screen device 100 also includes an angle sensor 70, which is used to detect the current angle of the overhead screen 10; when the current angle is different from the target angle, the second processor 23 controls the motion mechanism 50 to move according to the processed motion instruction to drive the overhead screen 10 to rotate to the target angle.

[0104] In particular, if the overhead screen 10 can be flipped relative to the roof 2000, the current angle of the overhead screen 10 can be the angle between the user interface of the overhead screen 10 and the roof 2000. If the overhead screen 10 can be rotated horizontally about the connection, the current angle of the overhead screen 10 can be the angle between the rotated overhead screen 10 and the initial position of the overhead screen 10.

[0105] See also Figure 1 、 Figure 2 and Figure 6If the angle sensor 70 detects that the current angle of the overhead screen 10 is different from the target angle, the angle sensor 70 may send a signal to the second processor 23. The second processor 23 may then control the motion mechanism 50 to rotate the overhead screen 10 based on the signal and the motion instruction. If the angle sensor 70 detects that the current angle of the overhead screen 10 is the same as the target angle, the angle sensor 70 may send a signal to the second processor 23. The second processor 23 may then stop controlling the motion mechanism 50 to rotate the overhead screen 10. For example, the target angle carried in the motion instruction is 90°, and the angle sensor 70 detects that the current angle of the overhead screen 10 is 60°. In this case, the angle sensor 70 transmits the angle signal to the second processor 23. The second processor 23 controls the motion mechanism 50 to rotate the overhead screen 10 based on the signal and the motion instruction. If the angle sensor 70 detects that the current angle of the overhead screen 10 is 90°, the angle sensor 70 may transmit the angle signal to the second processor 23. The second processor 23 may then stop controlling the motion mechanism 50 to rotate the overhead screen 10.

[0106] When the overhead screen device 100 includes an angle sensor 70, the angle sensor 70 detects the angle of the overhead screen 10 and transmits the angle signal to the second processor 23. The second processor 23 can accurately control the rotation angle of the overhead screen 10 through the motion mechanism 50, and the rotation error of the overhead screen 10 during the rotation process is small.

[0107] See also Figure 1 、 Figure 2 and Figure 7 In some embodiments, 02: controlling the top screen 10 according to the first control instruction includes:

[0108] 022: Control the top screen 10 to perform a predetermined function at a predetermined time according to the timing function instruction.

[0109] In some embodiments, the first control instruction includes a timing function instruction, which is obtained through one of the overhead screen 10, the armrest screen 501 and the central control screen 301; the processing module 20 is used to control the overhead screen 10 to perform a predetermined function at a predetermined time according to the timing function instruction.

[0110] Passengers can input timing function instructions through the overhead screen 10, the armrest screen 501 or the central control screen 301. When the processing module 20 receives the timing function instruction, the processing module 20 can control the overhead screen 10 to perform a predetermined function within a predetermined time. The predetermined time can be, but is not limited to, 0.5 hours, 1 hour, 2 hours or other time. The predetermined functions include, but are not limited to, a shutdown function, a reminder function, and an alarm function. For example, after the processing module 20 receives the timing function instruction, the processing module 20 can control the overhead screen 10 to shut down after 0.5 hours, the processing module 20 can control the overhead screen 10 to remind the passenger after 1 hour, the processing module 20 can control the overhead screen 10 to turn on the alarm after 1 hour, and so on.

[0111] Passengers input timed function commands via the overhead screen 10, central control screen 301, or armrest screen 501. Upon receiving the timed function commands, the processing module 20 controls the overhead screen 10 to execute the predetermined function at the predetermined time. The overhead screen 10 can meet the diverse needs of passengers in different scenarios, providing a good user experience and making control of the overhead screen 10 relatively simple.

[0112] See also Figure 1 、 Figure 2 and Figure 8 In some embodiments, 022: controlling the top screen device 100 to perform a predetermined function at a predetermined time according to the timing function instruction includes:

[0113] 0221: Control the top screen 10 to perform a predetermined function at a predetermined time according to the timing function instruction.

[0114] In some embodiments, the first processor 21 is configured to execute a predetermined function at a predetermined time according to a timed function instruction.

[0115] Passengers can input timing function instructions through the overhead screen 10, the armrest screen 501 or the central control screen 301. When the first processor 21 receives the timing function instruction, it processes the timing function instruction and then turns on the timing function. The first processor 21 can control the overhead screen 10 to perform a predetermined function within a predetermined time.

[0116] See also Figure 1 、 Figure 2 and Figure 9 In some embodiments, 02: controlling the top screen device 100 according to the first control instruction includes:

[0117] 023: Control the top screen 10 to power on according to the power-on instruction, and / or control the top screen 10 to power off according to the power-off instruction.

[0118] In some embodiments, the first control instruction includes a power-on instruction and a power-off instruction, and the power-on instruction and the power-off instruction are obtained through one of the armrest screen 501 and the central control screen 301; the processing module 20 is used to control the top screen 10 to power on according to the power-on instruction, and / or control the top screen 10 to power off according to the power-off instruction.

[0119] See also Figure 1 、 Figure 2 and Figure 9 In one embodiment, a passenger can input power-on and power-off commands through the central control screen 301. When a passenger needs to use the overhead screen 10, the passenger touches the central control screen 301 to input a power-on command. After the processing module 20 receives the power-on command, the processing module 20 controls the overhead screen 10 to power on. When the passenger no longer needs to use the overhead screen 10, the passenger touches the central control screen 301 to input a power-off command. After the processing module 20 receives the power-off command, the processing module 20 controls the overhead screen 10 to power off. In this case, the front passenger can more conveniently control the power on and off of the overhead screen 10.

[0120] In another embodiment, passengers can input power-on and power-off commands via the armrest screen 501. When a passenger needs to use the overhead screen 10, they touch the armrest screen 501 to input a power-on command. Upon receiving the power-on command, the processing module 20 controls the overhead screen 10 to power on. When a passenger no longer needs to use the overhead screen 10, they touch the armrest screen 501 to input a power-off command. Upon receiving the power-off command, the processing module 20 controls the overhead screen 10 to power off. This makes it more convenient for rear passengers to control the powering on and off of the overhead screen 10.

[0121] In another embodiment, both the central control screen 301 and the armrest screen 501 can be used to input power-on and power-off commands. In this case, both front and rear passengers can conveniently control the power-on and power-off of the overhead screen 10. The vehicle 10000 has multiple means of controlling the power-on and power-off of the overhead screen 10, providing greater flexibility and simplicity for passengers. Both the central control screen 301 and the armrest screen 501 of the present application can be used to input power-on and power-off commands.

[0122] See also Figure 1 、 Figure 2 and Figure 10 Specifically, in some embodiments, 023: controlling the top screen 10 to power on according to the power-on instruction includes:

[0123] 0231: Get the power-on command;

[0124] 0233: Responding to the power-on command, obtaining the video image from the memory 33 and sending the video signal carrying the video image to the top screen 10; and

[0125] 0235: Display the video image carried by the video signal.

[0126] In some embodiments, the first control instruction includes a power-on instruction; the host 30 includes a memory 33 connected to the first processor 21, the memory 33 stores a video image, and the first processor 21 is used to obtain the power-on instruction; the first processor 21 is also used to respond to the power-on instruction, obtain the video image from the memory 33, and send a video signal carrying the video image to the overhead screen 10; and the overhead screen 10 is used to display the video screen carried by the video signal.

[0127] Memory 33 is used to store video images. After a passenger inputs a power-on command via the central control screen 301 or the armrest screen 501, the first processor 21 receives the power-on command, responds to the command, and communicates with memory 33. The first processor 21 retrieves the video signal from memory 33 and transmits it to the overhead screen 10, allowing the overhead screen 10 to display the video image upon powering on.

[0128] The overhead screen device 100 can be powered on after receiving the power-on command and display the video image through the overhead screen 10. The passenger can easily control the power-on of the overhead screen device 100, and there are many control methods for powering on the overhead screen device 100, so the passenger has a good user experience.

[0129] See also Figure 1 、 Figure 2 and Figure 11 In some embodiments, 0233: sending a video signal to the top screen 10 includes:

[0130] 02331: Send video signal to serializer 35;

[0131] 02333: Convert the video signal from a parallel data stream form to a serial data stream form and transmit it to the deserializer 11; and

[0132] 02335: Convert the video signal from a serial data stream to a parallel data stream and transmit it to the display interface of the top screen 10.

[0133] In some embodiments, the host 30 also includes a serializer 35, and a deserializer 11 is provided in the overhead screen 10; the first processor 21 is used to send the video signal to the serializer 35; the serializer 35 is used to convert the video signal from a parallel data stream form to a serial data stream form, and transmit it to the deserializer 11; and the deserializer 11 is used to convert the video signal from a serial data stream form to a parallel data stream form, and transmit it to the display interface of the overhead screen 10.

[0134] See also Figure 1 The serializer 35 is used to convert parallel data streams into serial data streams. Specifically, the serializer 35 converts the High-Definition Multimedia Interface (HDMI) signal sent from the first processor 21 into a serial data stream signal (Gigabit Multimedia Serial Link 2, GMSL2). This conversion process can increase the transmission speed and distance of the video signal within a limited transmission bandwidth, thereby increasing the transmission rate of the video signal. The serializer 35 can also send and receive control data, enabling full-duplex communication of video and data signals on the cable. The deserializer 11 is used to convert the serial data stream into a parallel data stream. Specifically, the deserializer 11 can convert the GMSL2 serial signal transmitted from the serializer 35 into an Open LVDS Display Interface (OLDI) signal. That is, the deserializer 11 is used to restore the signal received from the serializer 35 to the original video signal, so that the video signal can be transmitted to the overhead display 10 for display on the user interface of the overhead display 10. The deserializer 11 can also send and receive control data to achieve full-duplex communication of video and data signals on the cable.

[0135] A passenger inputs a power-on command through the central control screen 301 or the armrest screen 501, and the first processor 21 can obtain the power-on command. After processing the power-on command, the first processor 21 can control the host 30 to power on, thereby transmitting the video signal retrieved from the memory 33 to the serializer 35. The serializer 35 converts the video signal from a parallel data stream to a serial data stream (GMSL2). After the GMSL2 serial signal is transmitted at a high frequency in the serializer 35, it is output to the deserializer 11. After the deserializer 11 processes the signal, that is, converts the serial signal into a parallel signal, the deserializer 11 transmits the video signal to the overhead screen 10, so that the display interface of the overhead screen 10 can display the video image.

[0136] See also Figure 1 、 Figure 2 and Figure 11The serializer 35 and deserializer 11 within the overhead screen device 100 accelerate the transmission rate of video signals. After a passenger inputs a power-on command via the central control screen 301 or armrest screen 501, the first processor 21 controls the host computer 30 to power on. Once powered on, the host computer 30 quickly transmits the video signal to the overhead screen 10, displaying the video on the user interface of the overhead screen 10. After the overhead screen device 100 powers on, the video image on the overhead screen 10 displays promptly, avoiding signal delays.

[0137] When the overhead screen 10 needs to be controlled, the passenger inputs a signal through the central control screen 301, the armrest screen 501 and the user interface of the overhead screen 10. The signal is processed by the first processor 21 in the host 30, and then sent by the first processor 21 to the second processor 23 via a CAN signal or converted into a GMSL2 signal through the serializer 35 and sent to the overhead screen 10 to complete the corresponding operation.

[0138] See also Figure 1 、 Figure 2 and Figure 12 In some embodiments, the control method further comprises:

[0139] 03: Obtain the second control instruction input through the armrest screen 501 or the central control screen 301; and

[0140] 04: Control seat 3000 according to the second control instruction.

[0141] In some embodiments, the vehicle 10000 further includes a body controller 700, and the armrest screen 501 or the central control screen 301 is used to input a second control instruction; the body controller 700 is used to control the seat 3000 according to the second control instruction.

[0142] The second control instruction is an instruction for controlling the seat 3000 in the vehicle 10000. In one embodiment, the central control screen 301 is used to input the second control instruction. In this case, the central control screen 301 is connected to the body controller 700. If a passenger needs to adjust the seat 3000, the passenger touches the central control screen 301 to input the second control instruction, and the second control instruction is transmitted to the body controller 700 in the form of a CAN signal. After receiving the second control instruction, the body controller 700 can control the seat 3000 to achieve the target state. In another embodiment, the armrest screen 501 is used to input the second control instruction. In this case, the armrest screen 501 is connected to the body controller 700. If a passenger needs to adjust the seat 3000, the passenger touches the armrest screen 501 to input the second control instruction, and the second control instruction is transmitted to the body controller 700 in the form of a CAN signal. After receiving the second control instruction, the body controller 700 may control the seat 3000 so that the seat 3000 is in a target state.

[0143] See also Figure 1 、 Figure 2 and Figure 13 In the embodiment of the present application, both the central control screen 301 and the armrest screen 501 can be used to input the second control command. In this case, the passenger has more ways to control the seat 3000, and the passenger's control operation of the seat 3000 is relatively simple, which provides a better passenger experience.

[0144] Specifically, in some embodiments, 04: controlling the seat 3000 according to the second control instruction includes:

[0145] 041: Adjust the posture of the seat 3000 and / or the distance between the seat 3000 and the overhead screen device 100 according to the seat adjustment instruction.

[0146] In some embodiments, the second control instruction includes a seat adjustment instruction; the body controller 700 is used to adjust the posture of the seat 3000 and / or the distance of the seat 3000 relative to the overhead screen device 100 according to the seat adjustment instruction.

[0147] See also Figure 1 and Figure 2The body controller 700 may adjust the posture of the seat 3000 by adjusting the tilt angle of the seat backrest relative to the seat cushion, so that the seat 3000 can adapt to the passenger's needs in different scenarios. For example, if a passenger needs to maintain a more upright sitting posture, the body controller 700 may control the angle between the seat backrest and the seat cushion to be approximately 90° after the passenger enters a seat adjustment command via the central control screen 301 or the armrest screen 501. If a passenger needs to reduce fatigue during a long-distance drive of the vehicle 10000, the body controller 700 may control the angle between the seat backrest and the seat cushion to be greater than 90° (e.g., 120° or 130°) after the passenger enters a seat adjustment command via the central control screen 301 or the armrest screen 501. When a passenger needs to rest, after the passenger inputs a seat adjustment instruction through the central control screen 301 or the armrest screen 501, the body controller 700 can control the seat 3000 to a nearly lying position (for example, the angle between the backrest of the seat 3000 and the seat cushion of the seat 3000 can be 170°, or 180°, etc.).

[0148] The body controller 700 can adjust the distance between the seat 3000 and the overhead screen device 100 by controlling the base of the seat 3000 to slide relative to the roof 2000, thereby adjusting the distance between the seat 3000 and the overhead screen device 100, so that the seat 3000 can adapt to the passenger's usage needs in different scenarios. For example, when a passenger is watching the overhead screen 10 and needs to pay attention to eye protection, after the passenger inputs a seat adjustment instruction through the central control screen 301 or the armrest screen 501, the body controller 700 can control the distance between the seat 3000 and the overhead screen device 100 (for example, controlling the distance between the seat 3000 and the overhead screen device 100 to 1mm or 1.5mm, etc.).

[0149] After the passenger inputs a seat adjustment instruction via the central control screen 301 or the armrest screen 501, the vehicle body controller 700 can adjust the seat 3000 to the desired position. Passengers can adjust the seat 3000 in a relatively simple manner, and there are many ways to adjust the seat 3000, making it convenient for passengers to adjust the seat 3000.

[0150] See also Figure 1 、 Figure 2 and Figure 14 In some embodiments, 041: adjusting the posture of the seat 3000 according to the seat adjustment instruction includes:

[0151] 0411: Obtaining seat adjustment instructions transmitted from the armrest screen device 500 or the central control screen device 300; and

[0152] 0413: According to the seat adjustment instruction, the adjustment mechanism 800 is controlled to move to drive the seat 3000 to move, so as to change the posture of the seat 3000 and / or the distance between the seat 3000 and the overhead screen device 100.

[0153] In some embodiments, the vehicle 10000 also includes an adjustment mechanism 800, which is connected to both the body controller 700 and the seat 3000; the body controller 700 is also used to obtain seat adjustment instructions transmitted from the armrest screen device 500 or the central control screen device 300; and the body controller 700 is also used to control the movement of the adjustment mechanism 800 according to the seat adjustment instructions to drive the seat 3000 to move, so as to change the posture of the seat 3000 and / or the distance of the seat 3000 relative to the overhead screen device 100.

[0154] The adjustment mechanism 800 is used to adjust the posture of the seat 3000 and / or the distance between the seat 3000 and the overhead screen device 100. When a passenger needs to adjust the seat 3000, the passenger inputs a seat adjustment command through the central control screen 301 or the armrest screen 501. After the body controller 700 receives the seat 3000 control command, the body controller 700 controls the movement of the adjustment mechanism 800. During the movement, the adjustment mechanism 800 drives the seat 3000 to move, thereby adjusting the seat 3000 to the desired target state.

[0155] See also Figure 1 、 Figure 2 and Figure 15 In some embodiments, the control method further comprises:

[0156] 05: Obtaining the third control instruction input by the user through the central control screen 301; and

[0157] 06: Lock, unlock or customize the control functions of the armrest screen 501 according to the third control instruction.

[0158] In some embodiments, the armrest screen device 500 also includes a third processor 503 electrically connected to the armrest screen 501; the central control screen 301 is also used to input a third control instruction; the third processor 503 is used to lock, unlock or customize the control function of the armrest screen 501 according to the third control instruction.

[0159] Among them, when the third processor 503 locks the control function of the armrest screen 501, the armrest screen 501 does not respond to the second control instruction input by the passenger through the armrest screen 501 (that is, when the passenger inputs the seat adjustment instruction through the armrest screen 501, the seat 3000 does not move), and the armrest screen 501 also does not respond to the first control instruction input by the passenger through the armrest screen 501 (that is, when the passenger inputs the first control instruction through the armrest screen 501, the state of the overhead screen 10 does not change). At this time, after the front passenger adjusts the rear seat 3000 and the overhead screen 10 to the correct position, the control function of the armrest screen 501 can be locked by inputting the third control instruction to the central control screen 301, which can effectively prevent the rear passenger from accidentally touching the armrest screen 501.

[0160] If the front passenger allows rear passengers to use the control functions of armrest screen 501, the front passenger can unlock the control functions of armrest screen 501 by inputting a third control command into central control screen 301. After receiving the third control command, third processor 503 unlocks the control functions of armrest screen 501, allowing armrest screen 501 to respond to the first and second control commands input by the passenger via armrest screen 501. Inputting the first control command via armrest screen 501 changes the state of overhead screen 10. Inputting the second control command via armrest screen 501 changes the state of seat 3000.

[0161] If a front-seat passenger wishes to customize the control functions of armrest screen 501, the front-seat passenger can input a third control instruction into central control screen 301. After receiving the third control instruction, third processor 503 can customize the control functions of armrest screen 501. For example, if a passenger wishes to control the vehicle's air conditioning through armrest screen 501, the passenger can input the third control instruction into central control screen 301, and third processor 503 can enable armrest screen 501 to control the vehicle's air conditioning.

[0162] By inputting a third control command into the central control screen 301, the functions of the armrest screen 501 can be controlled. The front passenger can restrict the rear passenger's control of the armrest screen 501, which can meet the needs of passengers in different scenarios. The central control screen device 300 has multiple functions and a good user experience for passengers.

[0163] See also Figure 1 、 Figure 2 and Figure 16 In some embodiments, the control method further comprises:

[0164] 07: Obtaining the fourth control instruction input by the user through the central control screen 301; and

[0165] 08: Lock, unlock or customize the control functions of the top screen 10 according to the fourth control instruction.

[0166] In some embodiments, the processing module 20 includes a first processor 21; the central control screen 301 is also used to input a fourth control instruction; the first processor 21 is used to lock, unlock or customize the control function of the top screen 10 according to the fourth control instruction.

[0167] When the first processor 21 locks the control functions of the overhead screen 10, the overhead screen 10 does not respond to passenger manipulation of the overhead screen 10 through its user interface, nor does it respond to control of the overhead screen 10 by the armrest screen 501. In this case, after the front passenger has adjusted the overhead screen 10 to its proper position, they can input a fourth control command into the central control screen 301, thereby locking the control functions of the overhead screen 10. Rear passengers can view the video currently playing on the overhead screen 10 but cannot control it.

[0168] If the front passenger allows rear passengers to use the control functions of the overhead screen 10, the front passenger can unlock the control functions of the overhead screen 10 by inputting a fourth control command into the central control screen 301. After receiving the fourth control command, the first processor 21 unlocks the control functions of the overhead screen 10, allowing the overhead screen 10 to respond to the first control command input by the passenger via the armrest screen 501 and to control commands input by the passenger via the user interface of the overhead screen 10. The passenger can control the overhead screen 10 via both the armrest screen 501 and the user interface of the overhead screen 10.

[0169] If a front-seat passenger wishes to customize the control functions of overhead screen 10, the front-seat passenger can input a fourth control instruction into central control screen 301. After receiving the fourth control instruction, first processor 21 can customize the control functions of overhead screen 10. For example, if a passenger wishes to play audio on overhead screen 10, the passenger can input the fourth control instruction into central control screen 301, thereby enabling first processor 21 to enable audio playback on overhead screen 10.

[0170] By inputting the fourth control command into the central control screen 301, the functions of the overhead screen 10 can be controlled. The front passenger can restrict the rear passenger's control of the overhead screen 10, which can meet the passengers' usage conditions in different scenarios. The central control screen device 300 has multiple functions and provides a good user experience for passengers.

[0171] See also Figure 1 、 Figure 2 and Figure 17 In some embodiments, the control method further comprises:

[0172] 09: Obtaining the fifth control instruction input by the user through the central control screen 301; and

[0173] 010: Lock, unlock or customize the control function of the remote controller of vehicle 10000 according to the fifth control command.

[0174] In some embodiments, the vehicle 10000 also includes a remote control for controlling the overhead screen 10, and a fourth processor is provided in the remote control; the central control screen 301 is also used to input a fifth control instruction; the fourth processor is also used to lock, unlock or customize the control function of the remote control according to the fifth control instruction.

[0175] The remote control can control the movement, power on and off, or video switching of the overhead screen 10. When the fourth processor locks the control functions of the remote control, the overhead screen 10 will not respond to any passenger's manipulation of the overhead screen 10 via the remote control. This prevents passengers from accidentally touching the remote control, which could cause the overhead screen 10 to respond to functions other than those intended.

[0176] If the front passenger allows the rear passengers to use the control functions of the remote control, the front passenger can unlock the control functions of the remote control by inputting a fifth control command into the central control screen 301. After the fourth processor receives the fifth control command, the fourth processor unlocks the control functions of the remote control, so that the overhead screen 10 can respond to the control commands input by the passenger via the remote control.

[0177] If a front-seat passenger wishes to customize the control functions of the remote control, the passenger can input a fifth control instruction into central control screen 301. Upon receiving the fifth control instruction, the fourth processor can customize the control functions of the remote control. For example, if a passenger wishes to control the vehicle's air conditioning using the remote control, the passenger can input the fifth control instruction into central control screen 301, and the fourth processor can enable the remote control to control the vehicle's air conditioning.

[0178] By inputting the fifth control command into the central control screen 301, the functions of the remote control can be controlled. The front passenger can restrict the rear passengers from controlling the overhead screen 10 via the remote control, which can meet the needs of passengers in different scenarios. The central control screen device 300 has multiple functions and provides a good user experience for passengers.

[0179] See also Figure 1 、 Figure 2 and Figure 18 In some embodiments, the control method further comprises:

[0180] 011: Obtaining the sixth control instruction input by the user through the central control screen 301; and

[0181] 012: According to the sixth control instruction, the entertainment audio-visual system 900 is controlled to be in the supervision mode. In the supervision mode, the distance between the seat 3000 and the overhead screen device 100 is adjusted to within the preset distance range. During the display of the overhead screen 10, the armrest screen 501 can respond to the overhead screen 10 control instructions (motion instructions, timing function instructions, power-on instructions and power-off instructions) input through it for controlling the overhead screen device 100, and is prohibited from responding to the seat adjustment instructions input through it. The overhead screen 10 can respond to the overhead screen 10 control instructions input through it; after the overhead screen 10 is turned off, the armrest screen 501 resumes responding to the seat adjustment instructions input through it, and is prohibited from responding to the overhead screen 10 control instructions input through it, and the overhead screen 10 is prohibited from responding to the power-on instructions input through it.

[0182] See also Figure 1 、 Figure 2 and Figure 18 In some embodiments, the vehicle 10000 includes an entertainment audio-visual system 900, which includes an overhead screen device 100, a seat 3000, and an adjustment mechanism 800 for adjusting the seat 3000; the central control screen 301 is further used to input a sixth control instruction; in response to the sixth control instruction, the entertainment audio-visual system 900 is in a supervision mode. In the supervision mode, the adjustment mechanism 800 adjusts the distance between the seat 3000 and the overhead screen device 100 to a preset distance range. During the display period of the overhead screen 100, the armrest screen 50 1 can respond to the overhead screen 10 control instructions (motion instructions, timing function instructions, power-on instructions and power-off instructions) inputted therethrough for controlling the overhead screen device 100, and is prohibited from responding to the seat adjustment instructions inputted therethrough. The overhead screen 10 can respond to the overhead screen 10 control instructions inputted therethrough. After the overhead screen 10 is turned off, the armrest screen 501 resumes responding to the seat adjustment instructions inputted therethrough, and is prohibited from responding to the overhead screen 10 control instructions inputted therethrough. Furthermore, the armrest screen 501 is prohibited from responding to the power-on instructions inputted therethrough.

[0183] The supervision mode can be used for parents to supervise their children's use of the entertainment and audio-visual system 900. When the front passenger (parent) inputs the sixth control command via the central control screen 301, the entertainment and audio-visual system 900 enters the supervision mode. Upon receiving the sixth control command, the body controller 700 controls the adjustment mechanism 800 to adjust the distance between the seat 3000 and the overhead screen device 100 to within a preset distance range. For example, the preset distance range can be 1mm, 1.5mm, or 1.8mm. When the armrest screen device 500 receives the sixth control command, the passenger can control the overhead screen 10 via the armrest screen 501. However, the passenger cannot adjust the seat 3000 via the armrest screen 501, nor can the passenger control the seat 3000 via buttons on the seat 3000 (e.g., mechanical buttons or touch buttons). For example, the passenger can control the motion, timing, power on, and power off of the overhead screen 10 via the armrest screen 501. After the overhead screen 10 is turned off, the passenger can control the seat 3000 through the armrest screen 501, but the passenger cannot control the overhead screen 10 through the armrest screen 501, and the passenger cannot turn on the overhead screen 10 directly through the overhead screen device 100.

[0184] After the front passenger inputs the sixth control command to the central control screen 301, the entertainment audio and video mode can be in the supervision mode. At this time, parents can effectively supervise the entertainment audio and video system 900 in the back row to prevent children from overusing their eyes and becoming addicted.

[0185] See also Figure 1 、 Figure 2 and Figure 19 In some embodiments, the control method further comprises:

The overhead screen 10 can respond to overhead screen 10 control instructions input through it.

[0189] When the front passenger inputs the seventh control command via the central control screen 301, the entertainment audio-visual system 900 enters the enjoyment mode. At this point, upon receiving the seventh control command via the armrest screen device 500, the passenger can control the overhead screen 10 as needed via the armrest screen 501. The passenger can also control the adjustments of the seat 3000 via the armrest screen 501. For example, the passenger can control the movement, timing, power on, and power off of the overhead screen 10 via the armrest screen 501. The passenger can also adjust the position of the seat 3000 and / or the distance between the seat 3000 and the overhead screen device 100 via the armrest screen 501.

[0190] After the passenger inputs the seventh control instruction to the central control screen 301, the rear passengers can adjust the status of the overhead screen 10 and the posture of the seat 3000 as needed. They can also select the required application by touching the overhead screen 10, and the rear passengers have a better user experience.
