[0003] Luxury models now offer rear-seat passengers ceiling-mounted screens for audio, video, gaming, video conferencing, and other functions, providing a more versatile user experience. However, the opening, closing, angle, and movement of the ceiling screen can affect the passenger's viewing experience. The viewing angle of the ceiling screen differs when the seat is upright and when it is reclined, and external light reflects off the screen, causing glare. Different seating positions result in varying viewing distances, affecting screen clarity. These factors can easily cause visual fatigue when viewing the screen, and in severe cases, motion sickness.

[0041] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0042] In order to facilitate understanding of the implementation scheme provided in the embodiment of the present application, the relevant application background of the audio processing method provided in the embodiment of the present application is first explained.

[0043] Luxury models now offer rear-seat passengers ceiling-mounted screens for audio, video, gaming, video conferencing, and other functions, providing a more versatile user experience. However, the opening, closing, angle, and movement of the ceiling screen can affect the passenger's viewing experience. The viewing angle of the ceiling screen differs when the seat is upright and when it is reclined, and external light reflects off the screen, causing glare. Different seating positions result in varying viewing distances, affecting screen clarity. These factors can easily cause visual fatigue when viewing the screen, and in severe cases, motion sickness.

[0044] To address these issues, this solution controls the state of the ceiling screen based on at least one passenger's seat posture parameter. The screen's status indicates its angle and / or position. This means that the screen's position changes with different seat postures, resolving issues such as unclear or uncomfortable viewing for passengers.

[0045] In the existing technology, passenger characteristics are collected through additionally installed cameras, and the angle of the ceiling screen is adjusted based on the passenger characteristics. On the one hand, this increases the cost of hardware and software algorithms. On the other hand, the use of cameras leads to a lack of privacy in the rear space, greatly reducing the user experience.

[0046] Based on this, the solution provided by this program is to collect corresponding signals through the vehicle's own sensors without adding additional hardware costs, and automatically adjust the opening and closing, flip angle, displacement and other information of the ceiling screen based on the human visual comfort range and anti-screen glare principle.

[0047] like Figure 1 , which is a schematic diagram of the hardware structure provided by an embodiment of the present invention.

[0048] An embodiment of the present invention provides a control system for a ceiling screen. The control system 100 includes:

[0049] The seat sensor 110 is used to detect seat posture parameters of at least one passenger.

[0050] The controller 120 is connected to the seat sensor 110 and is used to control the state of the ceiling screen 130 according to the seat posture parameters of at least one passenger detected by the seat sensor. The state of the ceiling screen 130 is used to indicate the angle and / or position of the ceiling screen.

[0051] As an optional implementation, the seat sensor includes at least one of the following: an angle sensor, a pressure sensor, or a displacement sensor.

[0052] Furthermore, the above-mentioned angle sensor can be set on the backrest to detect the angle of the seat; the above-mentioned pressure sensor can be set on the surface of the seat cushion frame to detect the pressure of the seat, so that the controller determines whether there is someone on the seat based on the seat pressure; the above-mentioned displacement sensor can be set at any position of the seat to detect the distance the seat moves forward and backward.

[0053] Preferably, the above-mentioned angle sensors, pressure sensors or displacement sensors are all sensors in the seat system of the vehicle. Compared with the method of using additional cameras in the prior art, this solution uses the vehicle's own sensors. On the one hand, there is no need to increase additional costs. On the other hand, since these sensors do not involve the collection of user privacy information, there is no privacy security issue.

[0054] As an optional embodiment, the system further includes an adjustment mechanism connected to the controller, the controller being configured to control the state of the ceiling screen 130 via the adjustment mechanism. The ceiling screen 130 is connected to the adjustment mechanism, which enables angle and displacement adjustment of the ceiling screen 130. Angle adjustment includes vertical flipping and horizontal flipping, and displacement adjustment includes front-to-back and left-to-right displacement adjustment.

[0055] Further optionally, the above-mentioned adjustment mechanism includes: a first angle adjustment mechanism, a second angle adjustment mechanism, a third displacement adjustment mechanism and a fourth displacement adjustment mechanism, wherein: the first angle adjustment mechanism can realize the up and down flipping of the ceiling screen 130, the second angle adjustment mechanism can realize the left and right flipping of the ceiling screen 130, the third displacement adjustment mechanism can realize the front and back displacement adjustment of the ceiling screen 130, and the fourth displacement adjustment mechanism can realize the left and right displacement adjustment of the ceiling screen 130.

[0056] Illustratively, the first angle adjustment mechanism, the second angle adjustment mechanism, the third displacement adjustment mechanism, and the fourth displacement adjustment mechanism may be devices driven electrically or in other ways, and the present invention does not impose any limitation thereto.

[0057] Exemplarily, the above-mentioned controller may be a cockpit host computer, which is connected to a ceiling screen.

[0058] Exemplarily, the above system further includes: a power supply device for providing power to the controller, and the power supply device may be a low-voltage power supply device in a car.

[0059] For example, the above-mentioned ceiling screen can be placed in the middle of the ceiling inside the car, and is used for audio and video entertainment and other functions for rear passengers, and integrates a display screen assembly with an adjustment mechanism and a control unit.

[0060] The specific implementation process of the system is as follows:

[0061] When a passenger sits on a seat, the pressure sensor on the seat will detect the body weight signal and output it to the cockpit host; the cockpit host will determine whether it is a left passenger, a right passenger, or both passengers on the left and right seats based on the signal source.

[0062] When the rear passengers adjust the rear seat backrest angle, the angle sensor on the backrest inputs the backrest angle signal to the cockpit host; the cockpit host will calculate the position of the ceiling screen that is most suitable for the passengers to watch based on the backrest angle, and operate the adjustment mechanism to allow the ceiling screen to flip up and down at an angle of a.

[0063] When the rear passengers adjust the front and rear positions of the rear seats, the displacement sensors on the seats will transmit the displacement distance information to the cockpit host; the cockpit host will calculate the position of the ceiling screen that is most suitable for the passengers to watch based on the distance value, and operate the adjustment mechanism to allow the ceiling screen to move forward and backward by a distance b.

[0064] When the cockpit host does not receive the human body weight signal, the ceiling screen is in a closed state.

[0065] When the cockpit host only receives the human weight signal on the left or right side, the cockpit host calculates the optimal viewing angle for the passenger to view the ceiling screen at that position, and operates the adjustment mechanism to make the ceiling screen flip left or right by angle c and move left or right by distance d.

[0066] When the cockpit host receives the weight signal of the human body on the left and right seats, it will balance the viewing angles of the left and right passengers after calculation and command the ceiling screen to be in the initial open position.

[0067] The cockpit host improves the passenger's viewing comfort by commanding the flipping and movement of the adjustment mechanism through the optimal matching functional relationship between the passenger and the ceiling screen.

[0068] Further optionally, the above system further includes: an input component 140, which is connected to the controller 120; the controller 120 is further used to control the state of the ceiling screen according to the input signal of the input component.

[0069] Illustratively, the above-mentioned input components include but are not limited to: an operation panel, buttons, and a remote controller.

[0070] Optionally, when the above-mentioned input component is an operating panel, it can be set on the armrest of the seat to facilitate passengers to control the state of the ceiling screen through buttons on the operating panel, for example: controlling the ceiling screen to flip up and down, flip left and right, move forward and backward, and move left and right, etc. through buttons on the operating panel.

[0071] For example, when the above-mentioned input component is a button, it can specifically be a switch for manually adjusting the opening and closing, rotation, displacement, or special application scenarios of the ceiling screen.

[0072] To accommodate different passengers and different scenarios, if a passenger is dissatisfied with the automatically adjusted position of the ceiling screen, the passenger can use the above-mentioned input components to correct its position, thereby meeting the passenger's personalized needs.

[0073] The embodiment of the present invention also provides a method for controlling a ceiling screen. Figure 2 As shown, the method includes:

[0074] 201. Control a state of a ceiling screen based on a seat posture parameter of at least one passenger, where the state of the ceiling screen is used to indicate an angle and / or position of the ceiling screen.

[0075] Further optionally, before the above step 201, the method further includes:

[0076] 200. Obtain seat posture parameters of at least one passenger.

[0077] Exemplarily, the above-mentioned seat posture parameters include angle information and / or displacement information.

[0078] The above-mentioned angle information can be obtained by collecting the angle sensor provided on the vehicle backrest, and the above-mentioned displacement information can be obtained by collecting the displacement sensor on the vehicle seat.

[0079] Illustratively, different states of the ceiling screen correspond to different angles and / or positions.

[0080] As an optional implementation, the above step 201 specifically includes:

[0081] 2011. Searching for parameter information of the ceiling screen corresponding to the seat posture parameters of at least one passenger from the correspondence table.

[0082] 2012. Control the status of the ceiling screen according to the parameter information of the ceiling screen.

[0083] For example, the above correspondence table can be pre-stored in the vehicle or in the cloud, and the corresponding data can be obtained from the vehicle or the cloud as needed. The correspondence table is used to represent the correlation between the seat posture parameters and the parameters of the ceiling screen.

[0084] Here's a simple example to illustrate the aforementioned correspondence table: For example, if a1 represents a seat posture parameter, the corresponding ceiling screen parameter information is b1; if a2 represents a seat posture parameter, the corresponding ceiling screen parameter information is b2; and if a3 represents a seat posture parameter, the corresponding ceiling screen parameter information is b3. When the acquired seat posture parameter of at least one passenger is a1, the controller searches the aforementioned correspondence table and finds that the ceiling screen parameter information corresponding to a1 is b1. Based on b1, the controller controls the state of the ceiling screen, adjusting the angle and position of the ceiling screen according to the parameter corresponding to b1.

[0085] As a preferred implementation, the above 201 further specifically includes:

[0086] 2013. Calculating parameter information of the ceiling screen based on seat posture parameters of at least one passenger;

[0087] 2014. Control the status of the ceiling screen according to the parameter information of the ceiling screen.

[0088] Preferably, this solution can calculate the parameter information of the ceiling screen based on the passenger comfort mathematical model. Specifically: the input of the above-mentioned passenger comfort mathematical model is the seat posture parameter of at least one passenger, and the output is the parameter information of the ceiling screen. The passenger comfort mathematical model involves automobile ergonomics, etc., and is closely related to factors such as passenger body size, seat position, backrest angle, and ceiling screen position. The theoretical calculation formula can be derived by using the rear seat layout parameters in the early design, and the design formula can be corrected through data statistics during the later verification, so that the determined angle and / or position of the ceiling screen is more in line with passenger comfort. The specific calculation formula or model parameters of the mathematical model will not be described in detail here, as this is not the focus of this solution.

[0089] As an optional implementation, the above step 201 specifically includes the following:

[0090] 201a. When at least one passenger is in an initial seat position, control the ceiling screen to be in a first state.

[0091] For example, in this solution, the initial position of the ceiling screen can be set to the position when the ceiling screen is centered, and the position of the ceiling screen in the center is the origin. The first state mentioned above corresponds to the state when the passenger is in the initial seat position, that is, the initial position state after the ceiling screen is opened. The up and down flip angle of the ceiling screen in the initial position is the first threshold, the left and right flip angle is 0°, the front and back position is the second threshold, and the left and right displacement is 0 meters. For example, referring to Figure 3 As shown in the schematic diagram, when the passenger's initial seat position is a backrest angle of 25°, the corresponding control ceiling screen is in the first state, the up and down flip angle of the ceiling screen can be 110°, and the front and rear position is 1 meter.

[0092] Further optionally, the method also includes: detecting seat pressure data through a pressure sensor on the seat to determine whether there is someone on the rear seat, and further determining whether there is one person or two people based on whether the seat pressure data comes from the left seat or the right seat.

[0093] As an optional implementation manner, based on the above 201a, the method further includes:

[0094] 201b. When there is only one person in the rear seat, the ceiling screen is controlled to change from the first state to the second state according to the seat posture parameters.

[0095] For example, when there is only one person on the rear seat, it corresponds to the left passenger or the right passenger. The second state is the position of the ceiling screen when there is someone on the left seat or the right seat. At this time, the up-down flip angle of the ceiling screen is the first threshold, the left-right flip angle is the third threshold, the front-to-back position is the second threshold, and the left-right displacement is the fourth threshold. When the ceiling screen switches from the first state to the second state, its left-right flip angle and left-right displacement change, and the other parameters remain the same as the first state. For example, referring to Figure 4 As shown in the schematic diagram, when the ceiling screen is controlled to switch from the first state to the second state, the corresponding up and down flip angle of the ceiling screen can remain unchanged at 110°, the left flip angle (if it is a right passenger, it is a right flip angle) is c degrees, the front and rear positions remain unchanged at 1 meter, and the left translation (if it is a right passenger, it is to the right) is d meters.

[0096] Based on the above 201a, the method may further optionally include:

[0097] 201c. Obtaining seat posture change parameters;

[0098] 201d. Control the ceiling screen to change from the first state to the third state according to the seat posture change parameter.

[0099] For example, the seat posture change parameters can be detected by sensors on the vehicle, and the trigger for the seat posture change can be user input. For example, the user can manually adjust the seat angle or fore-aft movement according to their needs. Alternatively, the seat controller can automatically adjust the seat posture based on the passenger's own parameters (such as height, weight, etc.).

[0100] When the ceiling screen is in the first state (for example, the screen angle remains at 110°), if the passenger wants to increase the backrest angle before viewing the ceiling screen, the passenger's viewing distance from the screen will increase after adjusting the seat angle, and the light from the rear glass will easily be reflected by the ceiling screen and enter the human eye range, causing glare. Figure 5 As shown;

[0101] Optionally, in order to avoid such dazzling situation, this solution controls the ceiling screen to change from the first state to the third state according to the seat posture change parameter. Figure 6 As shown in the schematic diagram, when the ceiling screen is controlled to switch from the first state to the third state, the corresponding up and down flip angle of the ceiling screen flips a degree and moves back b meters. At this time, the viewing distance is improved, the reflection disappears and there is no glare.

[0102] As an optional implementation method, in order to allow passengers on both sides of the rear row to use the ceiling screen at the same time, the above-mentioned step 201 specifically includes: 201e, when there are people on the rear seats, controlling the ceiling screen to be in the first state.

[0103] For example, when there are passengers on both the left and right seats in the rear row, the state diagram of the ceiling screen is shown in FIG7 .

[0104] As an optional implementation method, in order to improve the passenger experience and maximize the use of the ceiling screen, based on the above-mentioned 201e, the method also includes: 201f, when there is only one person in the rear seat using the ceiling screen, controlling the ceiling screen to change from the first state to the second state.

[0105] For example, the user's input operation can be used to determine whether the ceiling screen is used by the left or right passenger. For example, a display panel can be set at the seat armrest. When the left or right passenger does not use the ceiling screen, a click operation can be performed on the display panel to inform the controller whether to use or not, and then the controller controls the ceiling screen to switch from the first state to the second state.

[0106] As an optional embodiment, to save space and avoid collisions, the method further includes: 202, when no one is using the ceiling screen in the rear seats, controlling the ceiling screen to be in a closed state. Alternatively, 203, when no one is using the rear seats, controlling the ceiling screen to be in a closed state.

[0107] For example, the closed state mentioned above means that the ceiling screen is in the center position and does not flip over. Figure 8 As shown in the schematic diagram, when the ceiling screen is in a closed state, the corresponding ceiling screen is located in the center of the roof above the front seats, and the up and down and left and right flip angles are 0 degrees.

[0108] As an optional implementation method, in order to meet the individual needs of different passengers and different scene requirements, passengers can also adjust the position of the ceiling screen by themselves. The above method also includes:

[0109] 204. Control the state of the ceiling screen according to the operation information input by the user.

[0110] Exemplarily, the above-mentioned user input may be manual operation input or voice input.

[0111] This solution controls the state of the ceiling screen based on at least one passenger's seat posture parameter. The screen's state indicates its angle and / or position. This allows the screen's position to change with different seat postures, resolving issues such as unclear or uncomfortable viewing for passengers.

[0112] like Figure 9 FIG. 1 is a flow chart of a control method according to an embodiment of the present invention. The method includes:

[0113] Step S01: After the vehicle is powered on, a connection signal between the seat pressure sensor and the cockpit host is obtained.

[0114] Step S02, determine whether the rear seat pressure exceeds the preset threshold of human body weight. If yes, proceed to step S03; if not, keep the ceiling screen in the closed state.

[0115] Step S03, determining whether the signal source is the left rear seat or the right rear seat, or both.

[0116] Step S04: If the pressure signal comes from the left seat, the ceiling screen flips left by c degrees and moves horizontally by d meters.

[0117] Step S05: If the pressure signal comes from the right seat, the ceiling screen flips right by c degrees and moves horizontally by d meters.

[0118] In step S06, if the pressure signal comes from the left and right seats, the ceiling screen remains in the initial position after opening, that is, in the first state, and the process goes to step S13.

[0119] Step S07, determine whether the left seat back angle has been adjusted, if yes, proceed to step S09, if not, maintain the state in step S04.

[0120] Step S08, determine whether the right seat back angle has been adjusted, if yes, proceed to step S10, if not, maintain the state in step S05.

[0121] Step S09: the ceiling screen is flipped up and down by a degree.

[0122] Step S10: The ceiling screen is flipped up and down by a degree.

[0123] Step S11, determine whether the left seat has forward and backward displacement, if yes, proceed to step 14, if not, maintain the state in step S09.

[0124] Step S12, determine whether the right seat has forward and backward displacement, if yes, proceed to step 15, if not, maintain the state in step S10.

[0125] Step S13, determine whether only passengers on one side are watching, if yes, proceed to step S16, if not, remain in the state of step S06.

[0126] Step S14: The ceiling screen moves forward and backward by b meters.

[0127] Step S15: The ceiling screen moves forward and backward by b meters.

[0128] Step S16: The passenger manually presses a button to correct the position.

[0129] Step S17, the left passenger checks to see if he is comfortable. If so, the comfortable state is maintained. If not, the process proceeds to step S16, where the left passenger manually presses a button to correct the position.

[0130] Step S18, the right passenger checks to see if he is comfortable. If so, the comfortable state is maintained. If not, the process proceeds to step S16, where the position is corrected manually by pressing a button.

[0131] As can be seen from the present invention, steps S04, S05, S09, S10, S14, and S15 are used to perform actions a, b, c, and d, thereby automatically adjusting the ceiling screen to a position that is comfortable for passengers to view. The specific action values involved involve human factors and automotive ergonomics, and are closely related to factors such as passenger body size, seat position, backrest angle, and ceiling screen position. A theoretical calculation formula can be derived using rear seat layout parameters during early design, and the design formula can be modified through statistical data during later verification to ensure that the automatically adjusted ceiling screen position is more consistent with passenger comfort.

[0132] The above-mentioned step S16 is to correct the position of the ceiling screen by manually adjusting the physical buttons in the scenario where the position of the ceiling screen does not meet the passenger comfort requirements, thereby improving the adaptability of the invention.

[0133] Figure 10 This is a schematic diagram of the structure of an electronic device according to an embodiment of this specification. The electronic device 1000 includes a processor 1001 with one or more processing cores, a memory 1002 with one or more computer-readable storage media, and a computer program stored in the memory 1002 and executable on the processor.
