[0058] The present application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts in the drawings or descriptions are numbered the same. Implementations not shown or described in the drawings are known to those of ordinary skill in the art. In the description of this application, the terms "first," "second," etc. are used solely to distinguish descriptions and are not to be construed as indicating or implying relative importance.

[0059] Please refer to Figures 1 to 16 The present application provides a seat posture control method that can be applied to a vehicle having a cabin (such as a car, a ship, etc.) that is equipped with a control system. The cabin is provided with multiple rows of seats with reversible backrests, and the control system can be used to control the seats to perform a bed-forming operation.

[0060] The present application also provides a control system, which may be an electronic system on a vehicle and may include a processor and a memory. The memory stores a computer program that, when executed by the processor, enables the control system to perform the corresponding steps of the seat posture control method described below.

[0061] Please refer to Figure 2 and Figure 11 As an example, the riding scene in the cockpit can be as follows Figure 2As shown, the seats are arranged in a two-one-two arrangement. The first row of seats in the cabin includes the first seat 100 (driver's seat) and the second seat 200 (passenger seat); the second row of seats is the third seat 300 (middle row left seat); the third row of seats includes the fifth seat 500 (third row left seat) and the fourth seat 400 (third row right seat). The bottom of each seat is provided with an electric slide rail that can slide longitudinally. Among them, the third seat 300 is also provided with an electric lateral slide rail 303 that supports lateral sliding, and a turntable assembly 301 that supports seat rotation. In addition, the first seat 100 and the second seat 200 can also be provided with a turntable assembly for seat rotation. Each seat is provided with an OCS (Occupant Classification System) sensor, which can be used to detect whether there are passengers, objects, etc. on the seat, as well as the type of passenger (such as adults, children).

[0062] Please refer again Figure 1 In this embodiment, the seat posture control method may include the following steps:

[0063] S10, obtaining an interactive instruction for performing bed transformation;

[0064] S20, based on the interactive instruction, selecting a target bed-making mode from a bed-making mode library, wherein the bed-making mode library includes at least two modes of a first mode representing one or two rows of beds, a second mode representing two or three rows of beds, a third mode representing one or two or three rows of beds, and a fourth mode of a custom bed-making mode;

[0065] S30, controlling seats in the cabin corresponding to the target bed-forming mode to perform a bed-forming action, wherein the cabin includes a first row of seats, a second row of seats, and a third row of seats with foldable backrests.

[0066] The following are the steps of the seat posture control method:

[0067] In step S10, the interaction instruction can be any one of an instruction generated based on a physical button, an instruction generated based on a touch display screen, an instruction generated based on collecting the gesture action image of the current user, and an instruction generated based on collecting the voice of the current user. The generated interaction instruction can be sent to the processor (or controller) of the control system.

[0068] It should be noted that the method of generating the interactive instruction can be flexibly selected according to the actual situation and is not specifically limited here.

[0069] The interaction instruction carries identification information corresponding to the bed configuration mode, which serves as index information for selecting the target bed configuration mode from the bed configuration mode library. For example, the bed configuration mode library stores multiple bed configuration modes and their corresponding ID information. The identification information in the interaction instruction is the ID information. For example, the identification information corresponding to the first mode is "1," the identification information corresponding to the second mode is "2," the identification information corresponding to the third mode is "3," and the identification information corresponding to the fourth mode is "4."

[0070] In the bed-making mode library, the ID information of each bed-making mode can be flexibly set according to actual conditions and is not specifically limited here.

[0071] In step S20, the target bed-making mode is the bed-making mode in the bed-making mode library that has the same identification information as the one in the interaction instruction. For example, if the identification information in the interaction instruction is "1," the first mode is selected as the target bed-making mode. If the identification information in the interaction instruction is "2," the second mode is selected as the target bed-making mode.

[0072] In this embodiment, the first mode of forming a bed with two rows means that the first row of seats and the second row of seats in the cabin together form a bed.

[0073] The second mode of the second and third row beds means that the second row seats and the third row seats in the cabin form a bed together.

[0074] The third mode of forming a bed with the first, second and third rows of seats means that the first row of seats, the second row of seats and the third row of seats in the cabin form a bed together.

[0075] The fourth custom bed mode allows users to select seats within the cabin to form a bed based on their preferences. For example, users can select two seats on the same side of the first and second rows to form a bed, without having to use all seats in the first and second rows.

[0076] It should be noted that the bed mode library can also store other modes different from the aforementioned four bed modes. The modes stored in the bed mode library can be flexibly set based on the number of seat rows and seat distribution in the cabin, and are not specifically limited here.

[0077] In step S30, different target bed-forming modes correspond to different seats. As an optional embodiment, step S30 controls the seats in the cabin corresponding to the target bed-forming modes to perform the bed-forming action, which may include:

[0078] When the target bed-forming mode is the first mode, the backrests of the first seat 100 and the second seat 200 in the first seat row are controlled to flip to a first preset angle for forming a bed, and the third seat 300 in the second seat row is controlled to rotate to a second preset angle for forming a bed, and the backrest of the third seat 300 is controlled to flip to the first preset angle;

[0079] Alternatively, the second seat 200 in the first row of seats is controlled to move to the second row, and the second seat 200 and the third seat 300 in the second row of seats are controlled to rotate so that the orientation of the second seat 200 and the third seat 300 is opposite to the orientation of the third row of seats, and the backrests of the second seat 200 and the third seat 300 are controlled to flip to the first preset angle for forming a bed, and the first seat 100 in the first row of seats is controlled to rotate to the second preset angle for forming a bed, and the backrest of the first seat 100 is controlled to flip to the first preset angle.

[0080] As an example, when the target bed mode is the first mode, the third seat 300 is controlled to rotate 90 degrees counterclockwise so that the backrest of the third seat 300 faces an empty position in the cabin, so that the backrest of the third seat 300 has enough space to flip over. Figure 3 Then, the backrest of the third seat 300 is controlled to flip so that the backrest is flush with the seat cushion. Figure 4 Next, the backrests of the first seat 100 and the second seat 200 are controlled to flip so that the backrests are flush with the seat cushions. Figure 5 At this time, the backrests of the first seat 100, the second seat 200 and the third seat 300 are all lowered, and the headrests of the longitudinal first seat 100 and the second seat 200 are abutted against the transverse third seat 300, thereby forming a "bed", see Figure 5 .

[0081] As another example, when the target bed-forming mode is the first mode, the second seat 200 is controlled to slide to the second row, and the second seat 200 and the third seat 300 are controlled to rotate 180° so that the second row seats are arranged opposite to the third row seats. Then, the backrests of the second seat 200 and the third seat 300 are controlled to flip over so that the backrests are flush with the seat cushion. In addition, the first seat 100 is controlled to rotate 90° counterclockwise so that the backrest of the first seat 100 faces the position where the co-pilot was originally located, and then the backrest of the first seat 100 is controlled to flip over so that the backrest is flush with the seat cushion. In this way, the headrests of the longitudinal second seat 200 and the third seat 300 are abutted against the transverse first seat 100, thereby forming a "bed", see Figure 13 .

[0082] In this embodiment, the first preset angle can be an angle where the backrest is flush with the seat cushion, for example, a 180° angle between the backrest and the seat cushion. The second preset angle can be 90° or close to 90°. The rotation direction can be flexibly determined based on the location of the third seat 300, as long as there is sufficient space for the backrest to be flat after rotation. In the first mode, the backrests of the fifth seat 500 and the fourth seat 400 remain in normal use and do not need to be flat.

[0083] As an optional implementation, step S30 of controlling the seat in the cabin corresponding to the target bed-forming mode to perform the bed-forming action may include:

[0084] When the target bed-forming mode is the second mode, the third seat 300 in the second row of seats is controlled to rotate to the second preset angle for forming a bed, and the backrest of the third seat 300 is controlled to flip to the first preset angle, and the backrests of the fourth seat 400 and the fifth seat 500 in the third row of seats are controlled to flip to the first preset angle for forming a bed.

[0085] As an example, when the target bed-forming mode is the second mode, the third seat 300 is controlled to rotate 90° counterclockwise so that the backrest of the third seat 300 faces an empty position in the cabin, thereby allowing enough space for the backrest of the third seat 300 to flip over. Then, the backrest of the third seat 300 is controlled to flip over so that the backrest is flush with the seat cushion. In addition, the backrests of the fourth seat 400 and the fifth seat 500 are controlled to flip over so that the backrest is flush with the seat cushion. At this time, the backrests of the fifth seat 500, the fourth seat 400 and the third seat 300 are all lowered, and the seat cushions of the fifth seat 500 and the fourth seat 400 are against the horizontal third seat 300, thereby forming a "bed", see Figure 6 In the second mode, the backrests of the first seat 100 and the second seat 200 maintain a normal use state and do not need to be laid flat.

[0086] As an optional implementation, step S30 of controlling the seat in the cabin corresponding to the target bed-forming mode to perform the bed-forming action may include:

[0087] When the target bed-forming mode is the third mode, the backrests of the first seat 100 and the second seat 200 in the first seat row are controlled to flip to a first preset angle for forming a bed, the third seat 300 in the second seat row is controlled to rotate to a second preset angle for forming a bed, and the backrest of the third seat 300 is controlled to flip to the first preset angle, and the backrests of the fourth seat 400 and the fifth seat 500 in the third seat row are controlled to flip to the first preset angle for forming a bed;

[0088] Alternatively, the second seat 200 in the first row of seats is controlled to move to the second row, and the second seat 200 and the third seat 300 in the second row of seats are controlled to rotate so that the orientation of the second seat 200 and the third seat 300 is opposite to that of the third row of seats, and the backrests of the second seat 200 and the third seat 300 are controlled to flip to the first preset angle for forming a bed, the first seat 100 in the first row of seats is controlled to rotate to the second preset angle for forming a bed, the backrest of the first seat 100 is controlled to flip to the first preset angle, and the backrests of the fourth seat 400 and the fifth seat 500 in the third row of seats are controlled to flip to the first preset angle for forming a bed.

[0089] As an example, when the target bed-forming mode is the third mode, the backrests of the first seat 100, the second seat 200, the fourth seat 400 and the fifth seat 500 are controlled to flip over so that the backrests are flush with the seat cushion. In addition, the third seat 300 is controlled to rotate 90° counterclockwise so that the backrest of the third seat 300 faces an empty position in the cabin, so that there is enough space for the backrest of the third seat 300 to flip over. Then, the backrest of the third seat 300 is controlled to flip over so that the backrest is flush with the seat cushion. At this time, the longitudinal backrests of the first seat 100, the second seat 200, the fourth seat 400 and the fifth seat 500, and the transverse backrest of the third seat 300 are all lowered to form a "bed", see Figure 7 .

[0090] As another example, the second seat 200 is controlled to slide to the second row, and the second seat 200 and the third seat 300 are controlled to rotate 180° so that the second row seats are arranged opposite to the third row seats. Then, the backrests of the second seat 200, the third seat 300, the fourth seat 400 and the fifth seat 500 are controlled to flip over so that the backrests are flush with the seat cushion. In addition, the first seat 100 is controlled to rotate 90° counterclockwise so that the backrest of the first seat 100 faces the position where the co-pilot was originally located, and then the backrest of the first seat 100 is controlled to flip over so that the backrest is flush with the seat cushion. In this way, the longitudinal second seat 200, the third seat 300, the fourth seat 400 and the fifth seat 500, together with the transverse first seat 100, form a "bed", see Figure 14 .

[0091] As an optional implementation, step S30 of controlling the seat in the cabin corresponding to the target bed-forming mode to perform the bed-forming action may include:

[0092] When the target bed-forming mode is the fourth mode, the backrests of the seats corresponding to the fourth mode are controlled to flip to a first preset angle for forming a bed.

[0093] In the custom bed mode, users can select the adjacent seats in the front and back of the cabin to form a bed according to their needs. For example, if the cabin has two rows of seats, the first row of seats can be rotated 180 degrees, and then the backrests of the first and second rows of seats can be folded flat to form a bed. Figure 15 For example, when the seats in the cabin are arranged in a 2:2 layout, the second seat 200 can be moved to the second row, and the first seat 100, the second seat 200 and the fifth seat 500 can be selected to form a bed. Figure 16 .

[0094] As an optional implementation, between step S20 and step S30, the method may further include:

[0095] detecting, by a first sensor assembly, whether the current position of each seat corresponding to the target bed-forming mode is within a corresponding preset area;

[0096] A seat that is not within the preset area is taken as a target seat, and a sliding mechanism is controlled to drive the target seat to move into the corresponding preset area, wherein the sliding mechanism is arranged at the bottom of the target seat.

[0097] In this embodiment, the first sensor assembly may include a position sensor provided on each seat, which can detect the relative position of each seat in the cabin. When it is necessary to enter the bed-forming mode, it is necessary to ensure that the position of the seat is within the corresponding preset area of ​​the cabin to ensure that there is enough space for the seat backrest to be laid flat, and that the spacing between the seats after the bed is formed is appropriate (or there is no spacing). The same seat may have different positions in the preset area of ​​the cabin in different bed-forming modes. The preset area can be flexibly planned according to the actual bed-forming effect and is not specifically limited here.

[0098] Controlling the sliding mechanism to drive the target seat to move to the corresponding preset area may include:

[0099] During the movement of the target seat driven by the sliding mechanism, if it is detected that the driving force of the sliding mechanism is greater than or equal to a preset threshold indicating the presence of an obstruction, the sliding mechanism is controlled to stop sliding, and a prompt module is controlled to issue a warning prompt message indicating the presence of an obstruction;

[0100] When the duration of stopping sliding is greater than or equal to the preset duration, the sliding mechanism is controlled to continue to drive the target seat to move, and the driving force of the sliding mechanism is detected until the target seat moves into the corresponding preset area, or the sliding mechanism repeatedly drives the target seat to move a preset number of times.

[0101] In this embodiment, the sliding mechanism can be an electric slide rail that can drive the seat to slide along the rail. The prompt module can be a central control display screen, a speaker, etc. of the vehicle.

[0102] During the sliding process of the seat driven by the sliding mechanism, an anti-stuck mechanism is provided. That is, during the sliding process, if the seat is stuck due to an obstacle and cannot continue to slide (that is, the driving force of the sliding mechanism is greater than or equal to the preset threshold indicating the presence of an obstacle), the control system can control the sliding mechanism to stop sliding to avoid burning the motor due to the seat being stuck and continuing to control the sliding mechanism to slide. In addition, the vehicle-mounted display screen can be controlled to play an animation to guide the user to remove the obstacle, and the speaker can be controlled to play a prompt voice similar to "Please remove the obstacle". In addition, the control system can issue a prompt for the stuck seat according to the control prompt module. That is, the prompt content includes the name of the stuck seat, so that the user can quickly locate the seat with abnormal sliding.

[0103] It should be noted that the driving force of the sliding mechanism to drive the seat to slide can be detected by a torque sensor, and the preset thresholds, preset time, preset number of times and other thresholds can be flexibly set according to actual conditions, and no specific restrictions are made here.

[0104] As an optional implementation, between step S20 and step S30, the method may further include:

[0105] detecting, by a second sensor assembly, whether there is an occupant and / or object interfering with bed formation on a seat corresponding to the target bed-forming mode;

[0106] If there are passengers and / or objects that interfere with the bed-making, the control prompt module will issue a first prompt message to guide the passengers to leave the seats or move the objects on the seats. If there are no passengers and / or objects that interfere with the bed-making, the execution step is allowed to control the seats in the cabin corresponding to the target bed-making mode to perform the bed-making action.

[0107] In this embodiment, the second sensing component may include a camera and an OCS sensor within the cabin, capable of detecting whether there are any occupants, objects, or other factors that could interfere with the formation of a bed. If there are any occupants or objects on the seat, step S30 is not permitted. Furthermore, the display screen may be controlled to play an animation guiding the user to leave the seat or remove objects, as well as a voice prompt such as "Please leave the seat / Please remove objects from the seat." If there are no occupants or objects on the seat that could interfere with the formation of a bed, step S30 is permitted.

[0108] As an optional implementation, between step S20 and step S30, the method may further include:

[0109] detecting, by a third sensor assembly, whether there is an obstacle that prevents the seat from forming a bed within a conversion space corresponding to the target bed-forming mode;

[0110] When the obstacle exists in the conversion space, the control prompt module issues a second prompt message for guiding the user to move the obstacle away. When the obstacle does not exist in the conversion space, the execution step is allowed to control the seat in the cabin corresponding to the target bed-forming mode to perform the bed-forming action.

[0111] In this embodiment, the third sensing component may include a camera or lidar within the cabin, capable of detecting whether there are obstacles (e.g., headrests, passengers) in the space occupied by the seat-to-bed conversion. Specifically, if an obstacle exists in the conversion space, step S30 is prohibited, and the user is prompted to remove the obstacle or leave the conversion space. If no obstacle exists in the conversion space, step S30 is permitted.

[0112] As an optional implementation, before step S30, the method may further include:

[0113] Obtain vehicle operating condition data;

[0114] When the operating condition data indicates that the vehicle is in a parking state, the seat in the control cabin corresponding to the target bed-forming mode is allowed to perform the bed-forming action; wherein, when the operating condition data indicates that the vehicle is in a non-parking state, the interactive instruction is not responded to.

[0115] In this embodiment, the operating condition data may include, but is not limited to, vehicle speed, gear position, and other information. If the vehicle is not parked, step S30 is not permitted. If the vehicle is parked, step S30 is permitted. This improves driving safety and bed-making safety, preventing the safety of drivers and passengers from being affected by bed-making operations while the vehicle is in motion.

[0116] During the bed-forming process, the seat can be folded with or without the headrest. Seat layouts in the cabin include, but are not limited to, a 2:1:2 layout, a 1:2:2 layout, a 2:2:2 layout, and a 2:3 layout. Seats capable of rotation include, but are not limited to, the first seat 100, the second seat 200, the middle row seats, the third row seats, and all seats.

[0117] In this embodiment, when the seats involve seat backs that are folded down to form a bed at the same time, one of the seat backs can be folded down to form a single bed mode, such as Figure 16As shown, the seat backs of the middle row seats and the third row seats are not folded down, and the other seats form a single bed mode. The embodiments listed in the present invention include but are not limited to one or several of the seats being folded down to form a bed.

[0118] Please refer to Figure 11 The first seat 100 is provided with a first electric slide rail, a first electric backrest angle adjustment motor, a first OCS sensor and a first anti-pinch unit.

[0119] The second seat 200 may be provided with a second electric slide rail, a second electric backrest angle adjustment motor, a second OCS sensor, a second anti-pinch unit, and a second headrest 205 .

[0120] The third seat 300 may be provided with a rotating turntable assembly 301 , an electric longitudinal slide 302 , an electric lateral slide 303 , a third backrest motor, a third anti-pinch unit, a third OCS sensor, and a third headrest 307 .

[0121] The fourth seat 400 may be provided with a fourth electric slide rail, a fourth electric backrest angle adjustment motor, an electric seat cushion lifting motor, a fourth OCS sensor, and a fourth anti-pinch unit.

[0122] The fifth seat 500 may be provided with a fifth electric slide rail, a fifth electric backrest angle adjustment motor, an electric seat cushion lifting motor, a fifth OCS sensor, and a fifth anti-pinch unit.

[0123] Please refer to Figure 8 、 Figure 9 and Figure 10 , is a schematic structural diagram of the third seat 300 in this application. The third seat 300 is a rotating seat, which may include a rotating turntable assembly 301, an electric longitudinal slide 302, and an electric lateral slide 303.

[0124] The third seat 300 slides laterally into the cabin on powered lateral rails 303, allowing it to pivot around door panels and pillars. The third seat 300 rotates via a rotating turntable assembly 301, providing support for a bed and expanding the range of in-cabin seating options for passengers.

[0125] like Figure 3 and Figure 4 As shown, the third seat 300 slides laterally into the cabin and rotates 90°, and then, under the action of the third backrest motor, is laid flat backward to form a bed through the seat backrest.

[0126] like Figure 5As shown, after the backrest of the third seat 300 is laid flat, it slides backward to the rearmost position through the electric longitudinal slide rail 302; the first seat 100 and the front passenger seat slide to the frontmost position through the first electric slide rail and the front passenger seat electric slide rail, with a stroke of 200mm; then the seat backs are laid flat backward through the first electric backrest angle adjustment motor and the front passenger seat electric backrest angle adjustment motor, forming a scene where the first and second rows of seats become a bed.

[0127] like Figure 6 As shown, after the backrest of the third seat 300 is laid flat, it slides backward to the final position through the electric longitudinal slide rail 302; the fourth seat 400 and the fifth seat 500, under the action of the electric backrest angle adjustment motor and the electric seat cushion lifting motor, the seat cushions are adjusted backward and laid flat along with the backrest, and the seat cushions and the backrest overlap smoothly, see the reference combination patent; forming a scene where the second and third rows of seats become a bed.

[0128] like Figure 7 As shown, the front seats slide to the frontmost position and then lie flat backward with a forward travel of 200mm. The third seat 300 slides inward and rotates 90°, then lies flat backward, and then slides to the rearmost position with a backward travel of 40mm. The three rows of seats are laid flat backward, forming a scene where the first, second and third rows of seats become a bed.

[0129] like Figure 13 As shown, this is a unique 2-1-2 / 1-2-2 seat layout for driving scenarios. The passenger seat can slide to the front row via a long slide rail to form a 2-1-2 seat layout, or it can slide to the second row to form a 1-2-2 seat layout. The first seat 100, the passenger seat, and the third seat 300 are all rotating seats, providing support for a variety of bed scenarios.

[0130] like Figure 13 As shown, the front passenger seat slides to the second row position via a long slide rail, the first seat 100 is rotated 90° via a rotation unit, and the seat back is folded back flat; the front passenger seat and the third seat 300 are rotated 180° and then slide to the rearmost position, with the backrest folded back flat to form a bed scene at the front end of the cabin;

[0131] like Figure 14 As shown, in Figure 13 On the basis of the third row of seats, the backrest is folded back flat, and the seat cushion is linked with the backrest and smoothly overlapped with the backrest, forming an overall bed scene in the cabin.

[0132] like Figure 15 As shown, this is a unique 2-2 or 2-3 seat layout for driving scenarios, where the first seat 100 and the front passenger seat are both rotating seats, providing support for a variety of bed scenarios.

[0133] The first seat 100 and the front passenger seat rotate 180° and slide to the rearmost position, with the backrests folded backward. The backrests of the third row seats are all folded backward, and the seat cushions are linked with the backrests to overlap smoothly, forming an overall bed scene in the cabin.

[0134] Please refer to Figure 12 In this embodiment, the specific implementation process of the seat-to-bed can be as follows:

[0135] S100: Accepts user interaction instructions for bed transformation, which can be recognized by microphone K11. When the acquired voice matches the preset activation instruction, the instruction is started; for example, special instructions such as "Hello XX" and "Start interaction". At the same time, interactive control can also be performed through the seat control switch panel K21 and the central control screen touch panel K22. After startup, it is transmitted by the central controller A to the intelligent cockpit domain controller X for processing, and fed back to the head-up display, central control display, instrument display or central control panel display interface function area for display. The usage status of all vehicle seats is obtained through the vehicle-mounted camera G: wherein, the usage status parameters include at least the location; and interactive guidance is displayed in the vehicle-mounted system to guide users in switching all vehicle seats in the vehicle cabin;

[0136] S200: Determine and select a bed-forming mode based on the user's instruction. A custom bed-forming mode may also be configured based on the customer's needs, such as a single bed-forming mode with only one seat back folded down.

[0137] Mode 1: One or two rows form a bed;

[0138] Mode 2: two or three rows form a bed;

[0139] Mode 3: One, two, three rows form a bed;

[0140] Mode 4: Custom mode, such as prompting users to make choices through voice, and displaying, guiding and indicating the next operation on the central control screen guidance interface;

[0141] S300: Based on the user's instructions, the vehicle's driving state is detected to determine whether it is in the parking state. If the vehicle is not in the parking state, intelligent space transformation cannot be performed. The user is guided to park the vehicle through the vehicle guidance interface and voice broadcast. If the vehicle is in the parking state, the next step is entered.

[0142] S400: Based on the bed-forming mode, the infrared camera G and the seat OCS unit are used to determine whether there are passengers or objects on the seat that interfere with the bed-forming scenario;

[0143] S500: If there are passengers or objects interfering with the bed scene, the user is guided to leave or move away the interfering objects through the vehicle guidance interface and voice announcement;

[0144] Example: The user selects mode 1 to arrange the beds into 1-2 positions.

[0145] The vehicle is detected to be in the parked state. The infrared camera G and the seat OCS unit are used to detect that three rows of seats are occupied. If a large object is placed to the right of the third seat 300, the vehicle guidance interface and voice broadcast will remind the third row passengers to leave and move the large object to the right of the third seat 300.

[0146] S600: If there are no passengers or objects interfering with the bed-forming scene, the bed-forming scene switching is completed; after the bed-forming scene switching adjustment is completed, the current scene and completion status are fed back through the vehicle guidance interface and voice broadcast;

[0147] During the process of entering the bed scene adjustment, the occupant status and position are monitored in real time through the on-board camera G and anti-pinch unit to prevent the occupant from entering the bed scene adjustment space and causing safety hazards; if the occupant enters the conversion space and affects or hinders the bed scene adjustment, the adjustment will be stopped immediately, and the passenger will be reminded to leave through the on-board guidance interface and voice broadcast. The bed scene adjustment will continue after the occupant leaves.

[0148] The embodiment of the present application provides a car cabin with a unique car seat layout and a car seat with an electric lateral slide rail 303 and a rotating turntable. This unique layout and rotating seat are conducive to forming a variety of bed scenarios, which is more flexible and changeable than the existing model that can only form a single bed.

[0149] In addition, the seat cushion of the car seat is adjusted in conjunction with the backrest. After the backrest is laid flat, the seat cushion will automatically overlap smoothly with the backrest, which can improve the sleeping and rest comfort of the bed.

[0150] This application provides a complete control method and control system for flexible and changeable bed-making scenarios, and provides scalability of the control method, which is conducive to passengers adding more scene applications on their own, increasing the variability and fun of the cabin.
