The embodiments are not to be considered as limiting the scope of the present application. In the drawings, the sizes of layers and regions and the relative sizes of the same can be exaggerated for clarity. Like numbers refer to like elements throughout.

[0046] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and / or "comprising", when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof. As used herein the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0047] For a thorough understanding of the present application, reference will be made to the following detailed description, taken in conjunction with the accompanying drawings, in which: preferred embodiments of the present application will be described, but the present application can also comprise other embodiments.

[0048] The application provides a control method 100 of a zero-gravity seat of a vehicle, as shown in FIG. 1, comprising the following steps:

[0049] Step S110: obtaining a zero-gravity seat opening signal;

[0050] Step S120: in response to the zero-gravity seat opening signal, performing zero-gravity seat running environment detection;

[0051] Step S130: when a zero-gravity seat running environment safety signal is obtained, at least one of headrest height adjustment, shoulder support adjustment or waist support adjustment is performed, wherein the headrest, shoulder support and waist support are arranged on a backrest, and the headrest height adjustment, shoulder support adjustment or waist support adjustment comprises moving the headrest, shoulder support or waist support relative to the backrest.

[0052] Exemplarily, before the zero-gravity seat opening signal is obtained, the method further comprises: obtaining a zero-gravity seat opening and closing signal; in response to the zero-gravity seat opening and closing signal, obtaining a current state of the zero-gravity seat; when the current state of the zero-gravity seat is not in the zero-gravity mode, obtaining the zero-gravity seat opening signal; and when the current state of the zero-gravity seat is in the zero-gravity mode, obtaining a zero-gravity seat reset signal.

[0053] Exemplarily, the zero-gravity seat opening and closing signal is obtained through a physical button, a virtual button or voice.

[0054] In one embodiment, the physical and virtual buttons include one or more buttons for setting a zero-gravity seat mode for the front passenger seat, which can integrate one or more functions of zero-gravity seat on, pause, reset, memory, etc., wherein the physical button can be a physical button provided on the center console or the seat, and the virtual button can be a non-physical button provided on the human-vehicle interaction interface (e.g., the center console interface), which is not limited in the present application. When the user interacts with the above-mentioned physical button or the above-mentioned virtual button for a duration greater than a preset threshold (e.g., 3s), a zero-gravity seat opening and closing signal is obtained. By setting a preset interaction duration threshold, the zero-gravity seat mode can be prevented from being turned on due to accidental touch, ensuring the safety of the user and avoiding startling the user. At the same time, in order to avoid misunderstanding of the user, a pop-up window will appear on the center console interface when the button is pressed for a short time, prompting "long press to turn on this function". In addition, the user can also turn on the zero-gravity seat mode through voice, for example, the user issues a "zero-gravity on" or "zero-gravity reset" voice command, and the vehicle's multimedia system converts the voice command into a voice signal and sends it to the control system to obtain the zero-gravity seat opening and closing signal. It should be noted that the above-mentioned method of obtaining the zero-gravity seat opening and closing signal is only exemplary, and any method capable of obtaining the zero-gravity seat opening and closing signal can be applied to the present application.

[0055] Exemplarily, after obtaining the zero-gravity seat opening and closing signal, it further includes: obtaining a driving state in response to the zero-gravity seat opening and closing signal; when the driving state is parking, obtaining the current state of the zero-gravity seat; when the driving state is driving, the zero-gravity seat opening and closing signal is invalid.

[0056] In one embodiment, as shown in FIG. 2, after obtaining the zero-gravity seat opening and closing signal, it is first necessary to determine whether the current vehicle is in a parking state: when the vehicle is not in a parking state, the seat does not turn on the zero-gravity mode, and there is a voice prompt: "the function cannot be used in the driving state"; when the vehicle is in a parking state, it is necessary to further determine whether the current zero-gravity seat is in a zero-gravity posture: if the current seat is not in a zero-gravity posture, step S120 is continued; if the current seat is in a zero-gravity posture, a reset step is performed.

[0057] Next, step S120 is performed, and zero-gravity seat operating environment detection is performed in response to the zero-gravity seat opening signal. The zero-gravity seat operating environment detection includes: obtaining a rear seat occupancy state; when the rear seat occupancy state is no one in the rear seat, obtaining a rear seat back state; when the rear seat back state is not reclined, obtaining a zero-gravity seat operating environment safety signal.

[0058] In one embodiment, continuing to refer to FIG. 2, if the current seat is not in the zero-gravity position, it is determined whether there is a person in the rear seat: when there is a person in the rear seat, the seat is not opened in the zero-gravity mode, and a voice prompt is given: there is a person in the rear seat, and the zero-gravity mode cannot be opened; when there is no person in the rear seat, it is determined whether the rear seat back is folded down: when the rear seat back is folded down, the seat is not opened in the zero-gravity mode, and a voice prompt is given: the rear seat back is folded down, and the zero-gravity mode cannot be opened; when the rear seat back is not folded down, the zero-gravity mode can be normally opened.

[0059] By detecting the operating environment before adjusting the seat, the safety of the seat adjustment process can be improved. By sequentially performing the driving state detection, the current state detection of the zero-gravity seat, and the operating environment detection before opening the zero-gravity seat mode, the detection process is improved, and faults in the seat adjustment process are avoided, for example, when the rear seat occupancy state is not detected before the seat adjustment, it may threaten the personal safety of the rear seat occupant.

[0060] Next, step S130 is performed, and when the zero-gravity seat operating environment safety signal is obtained, at least one of the headrest height adjustment, the shoulder support adjustment, or the waist support adjustment is performed. Among them, the headrest, the shoulder support, and the waist support are arranged on the backrest, and the headrest height adjustment, the shoulder support adjustment, or the waist support adjustment includes moving the headrest, the shoulder support, or the waist support relative to the backrest.

[0061] Referring to FIG. 3, the zero-gravity seat of the automobile includes a headrest (1), a backrest (2), a shoulder support (3), a backrest side wing support (4), a waist support (5), a seat cushion (6), a seat cushion side wing support (7), a leg rest (8), and a slide rail (9).

[0062] In one embodiment, the headrest 1 includes a large-stroke electrically suspended sleep headrest arranged on the backrest 2. The headrest height adjustment includes moving the headrest 1 in a first direction, and the first direction includes a direction parallel or close to parallel (for example, the included angle with the surface of the backrest 2 is less than 20°) to the surface of the backrest 2. By increasing the moving stroke of the headrest, the zero-gravity seat of the automobile can be suitable for users of different heights, such as child users, and meet the head and neck support needs of a larger range of human bodies.

[0063] In an embodiment, the shoulder support 3 comprises two or more shoulder air bags arranged on the backrest 2, for example, four shoulder air bags on both sides. The waist support 5 comprises one or more waist air bags arranged on the backrest 2, for example, three waist air bags. The shoulder support adjustment comprises moving the shoulder support 3 in a second direction, and the waist support adjustment comprises moving the waist support 5 in the second direction, the second direction comprising a direction perpendicular or close to perpendicular (for example, an angle range of 70°-110° with the surface of the backrest 2) to the surface of the backrest 2. By adjusting the inflation amount of the shoulder air bag or the waist air bag through the pneumatic system, the degree of bulging of the shoulder air bag or the waist air bag in the direction perpendicular to the backrest 2 can be adjusted to provide appropriate support for the user's shoulders or waist and meet the user's comfort needs. In addition, the shoulder support 3 and the waist support 5 can be adjusted in linkage to meet the back support needs of the human body in the zero-gravity posture and the design posture. Furthermore, by arranging the backrest side wing support 4 and the seat cushion side wing support 7, the automobile zero-gravity seat can meet the comfort needs of passengers of different sizes.

[0064] In an embodiment, the control of the automobile zero-gravity seat comprises slide rail (9) adjustment, seat cushion (6) height adjustment, seat cushion (6) angle adjustment, backrest (2) adjustment, leg rest (8) adjustment, headrest (1) height adjustment, shoulder support (3) adjustment, waist support (5) adjustment, seat cushion side wing support (7) adjustment, and backrest side wing support (4) adjustment. In addition, headrest side wing adjustment can also be performed manually. Among them, the slide rail adjustment can adjust the front and rear positions of the seat, maximize the optimization of the zero-gravity layout space, and maximize the range of each adjustment posture of the seat in the current vehicle cabin environment. The large lying posture of the zero-gravity is realized through the seat cushion height adjustment, the seat cushion angle adjustment, the backrest adjustment, and the leg rest adjustment. The headrest adjustment realizes the needs of passengers of different heights for head and neck support in the large lying posture. The seat back contour adjustment is realized through the shoulder support adjustment and the waist support adjustment. The seat transverse support surface adjustment is realized through the seat cushion side wing support adjustment and the backrest side wing support adjustment to meet the needs of passengers of different sizes.

[0065] Exemplarily, when the zero-gravity seat operating environment safety signal is acquired, the zero-gravity seat is adjusted according to a preset opening sequence. The preset opening sequence comprises: first performing the slide rail adjustment and the headrest height adjustment, then performing the waist support adjustment and the shoulder support adjustment, and then sequentially performing the seat cushion height adjustment and the seat cushion angle adjustment, and finally performing the backrest angle adjustment.

[0066] Further, the zero-gravity seat opening further comprises leg rest adjustment: the rear leg rest is stowed during the execution of the slide rail adjustment and the headrest height adjustment; the leg rest is opened to a preset angle after the execution of the seat cushion height adjustment and the seat cushion angle adjustment. Further, the execution of the waist support adjustment and the shoulder support adjustment further comprises the steps of executing the backrest side wing support adjustment and the seat cushion side wing support adjustment.

[0067] In one embodiment, the zero-gravity seat opening is performed in the following four steps: Step 1: the slide rail (9) and the headrest (1) of the zero-gravity seat are moved to a designated position, the waist support (5), the shoulder support (3), the backrest side wing support (4), and the seat cushion side wing support (7) are adjusted according to a preset program, and the rear leg rest is stowed; Step 2: the zero-gravity seat cushion (6) is raised to the lowest; Step 3: the zero-gravity seat cushion (6) is adjusted to a designated angle, and the leg rest (8) is opened to a designated angle; Step 4: the zero-gravity seat backrest (2) is adjusted to a designated angle.

[0068] In one embodiment, when the zero-gravity seat is adjusted according to the above, further customized adjustment of the "headrest height", "backrest angle", "leg rest angle", "seat cushion angle", "waist support", and "shoulder support" can be performed to meet the fine adjustment requirements of the seat posture due to differences in customer body size.

[0069] In one embodiment, during the above adjustment process, pressing any physical button can stop the seat from moving. Pressing the zero-gravity button again will cause the seat to perform the same mode of action as before, for example, if the zero-gravity opening process is interrupted, pressing the zero-gravity button again for 3 seconds will cause the seat to continue moving to the zero-gravity position.

[0070] By opening the zero-gravity seat according to the above steps, the dynamic comfort of the user during the seat adjustment process is improved. At the same time, by adjusting the various components of the seat step by step, the problem of excessive current caused by synchronous adjustment is avoided.

[0071] Exemplarily, when the acquired signal is a zero-gravity seat reset signal, at least one of the headrest height adjustment, the shoulder support adjustment, or the waist support adjustment is performed in response to acquiring the zero-gravity seat reset signal. The headrest height adjustment comprises moving the headrest in a first direction, and the shoulder support adjustment or the waist support adjustment comprises moving the shoulder support or the waist support in a second direction, which is generally opposite to the moving direction in response to acquiring the zero-gravity seat opening signal, which will not be described here again.

[0072] Exemplarily, the control method of the automobile zero-gravity seat further comprises: in response to the zero-gravity seat reset signal, adjusting the zero-gravity seat according to a preset reset sequence, wherein the preset reset sequence comprises: first, sequentially performing seat cushion angle reset and seat cushion height reset, then performing waist support reset and shoulder support reset, then performing backrest angle reset, and finally performing slide rail reset and headrest height reset.

[0073] In one embodiment, the zero-gravity seat reset step is performed in the following four steps: first step: the zero-gravity seat cushion (6) and leg rest (8) are reset to the pre-opening position; second step: the zero-gravity seat cushion (6), waist support (5), shoulder support (3), backrest side wing support (4) and seat cushion side wing support (7) are reset to the pre-opening position; third step: the zero-gravity seat backrest (2) is reset to the pre-opening position; fourth step: the zero-gravity seat slide rail (9) and headrest (1) are reset to the pre-opening position, and the rear leg rest is reset to the pre-opening position.

[0074] In addition, considering safety issues, when the zero-gravity seat is in a zero-gravity state and the vehicle is started, a voice prompt will be given: the vehicle has started, for your safety, the seat will be reset in 10 seconds. During this period, if the occupant resets it by physical buttons, virtual buttons or voice, the zero-gravity seat will be reset immediately.

[0075] Exemplarily, after the zero-gravity seat is adjusted according to the preset opening sequence, the step of storing the position of the zero-gravity seat is further included.

[0076] In one embodiment, each adjusting motor of the zero-gravity seat is a Hall motor, which memorizes the current position through a Hall signal, and each air bag of each pneumatic system is separately designed with a pressure sensor on the loop of the pneumatic controller, which memorizes the form of the pneumatic system through the pressure in the air bag. In this way, when the zero-gravity seat is customized and adjusted, a pop-up window will appear on the central control interface after the seat is reset, asking whether to memorize the current adjusted zero-gravity position: if "yes" is selected, the memory setting of the zero-gravity part is entered, the current zero-gravity position can be named, and after the memory is successful, the position of the next zero-gravity function opening defaults to this memory position; if "no" is selected, no memory is performed and the pop-up window disappears. The stored zero-gravity position can be selected in the memory setting menu of the zero-gravity position as the subsequent zero-gravity opening position, including the recommended zero-gravity position when the factory is restored.

[0077] FIG. 4 shows a schematic block diagram of a control device 400 according to an embodiment of the present application. The control device 400 comprises a memory 410 and a processor 420.

[0078] The memory 410 stores program codes for implementing corresponding steps in the control method 100 of the automobile zero-gravity seat according to the embodiments of the present application.

[0079] The processor 420 is configured to execute the program codes stored in the memory 410 to perform corresponding steps of the control method 100 of the automobile zero-gravity seat according to the embodiments of the present application.

[0080] In addition, the present application also includes an automobile zero-gravity seat assembly, which comprises the automobile zero-gravity seat and the control device of the automobile zero-gravity seat as described above.

[0081] In addition, the present application also includes a vehicle, which comprises the automobile zero-gravity seat assembly as described above.
