Description

Technical Field

[0001] The present application relates to the field of artificial intelligence technology, and in particular to a seat adjustment method and a vehicle. Background Art

[0002] At present, in order to ensure the comfort of users when riding in cars, buses, high-speed trains, airplanes and other means of transportation, the comfort of seats can usually be adjusted. There are many ways to adjust the comfort of seats, such as providing seats with comfortable shapes, providing seats with flexible adjustable functions (such as adjustable backrests, ventilation and heating, massage functions, etc.).

[0003] However, the adjustment functions of some seats, such as adjusting the seat spacing and the seat back angle, improve the riding experience and comfort of the passengers on the seat, but will reduce the riding space for the rear passengers. This can improve the riding experience of the front passengers, but affect the riding experience of the rear passengers. Summary of the invention

[0004] The present application provides a seat adjustment method and a vehicle, which can ensure the comfort of a second user on a front seat while also taking into account the riding experience of a first user on a rear seat.

[0005] In order to achieve the above purpose, this application adopts the following technical solutions:

[0006] In a first aspect, a seat adjustment method is provided, which is applied to a vehicle, wherein the vehicle comprises at least a first seat and a second seat facing the same direction, the second seat is located in a row in front of the first seat, and the second seat corresponds to at least one adjustable item.

[0007] The method includes: a vehicle obtains first seat information of a first seat; when the first seat information indicates that there is a first user on the first seat, obtains adjustment restriction conditions corresponding to adjustable items of a second seat, wherein the adjustment restriction conditions are used to limit the adjustment range of the adjustable items; when a second user adjusts the adjustable items of the second seat, the adjustment operation of the second user is restricted based on the adjustment restriction conditions corresponding to the adjustable items.

[0008] The above method can limit the adjustment of the front seat according to the situation of the first user sitting on the rear seat, thereby reducing the impact of the adjustment of the front seat on the first user on the rear seat. While ensuring the comfort of the second user on the front seat, the riding experience of the first user on the rear seat can also be taken into consideration.

[0009] In an implementation method of the first aspect, the first seat information includes a pressure value corresponding to the first seat; when the pressure value corresponding to the first seat is greater than or equal to the first pressure value, the first seat information indicates that there is a first user on the first seat; when the pressure value corresponding to the first seat is less than the first pressure value, the first seat information indicates that there is no user on the first seat.

[0010] In this implementation, the pressure value corresponding to the first seat can reflect whether the first seat is occupied and the weight of the first user. When the pressure value corresponding to the first seat is greater than or equal to the first pressure value, the first seat information can indicate that the first user is on the first seat, and when the pressure value corresponding to the first seat is less than the first pressure value, the first seat information can indicate that there is no user on the first seat, or the effect of the adjustment of the second seat on the existing first user can be ignored (such as a child sitting on the first seat, etc.).

[0011] In an implementation of the first aspect, the adjustable item includes a backrest angle of a second seat, and the adjustment restriction condition includes limiting the angle range of adjusting the backrest angle of the second seat. When the pressure value corresponding to the first seat is greater than or equal to the first pressure value and less than the second pressure value, the vehicle obtains the first angle range corresponding to the backrest angle of the second seat. When the pressure value corresponding to the first seat is greater than or equal to the second pressure value and less than the third pressure value, the vehicle obtains the second angle range corresponding to the backrest angle of the second seat; the first angle range is greater than the second angle range.

[0012] In this implementation, when the pressure value corresponding to the first seat is in different ranges, the vehicle's restrictions on the second seat back angle are also different. This can fully consider the weight, fatness and other physical conditions of the rear users, and reduce the impact of the front users on the rear users when adjusting their seats.

[0013] In an implementation of the first aspect, the adjustable item includes the position of the second seat, and the adjustment restriction condition includes limiting the distance range for adjusting the position of the second seat. When the pressure value corresponding to the first seat is greater than or equal to the first pressure value and less than a fourth pressure value, the vehicle acquires the first distance range corresponding to the position of the second seat. When the pressure value corresponding to the first seat is greater than or equal to the fourth pressure value and less than a fifth pressure value, the vehicle acquires the second distance range corresponding to the position of the second seat; the first distance range is greater than the second distance range.

[0014] In this implementation, when the pressure value corresponding to the first seat is in different ranges, the restrictions of the vehicle on the second seat position are also different. This can fully consider the weight, fatness and other physical conditions of the rear users and reduce the impact of the front users adjusting their seats on the rear users.

[0015] In an implementation manner of the first aspect, the first seat information includes a first image corresponding to the first seat, and the first image indicates that there is a first user on the first seat.

[0016] In this implementation, the content included in the first image can reflect whether the first seat is occupied and the volume of space occupied by the first user.

[0017] In an implementable manner of the first aspect, the adjustable item includes a backrest angle of a second seat, and the adjustment restriction condition includes limiting the angle range of adjusting the backrest angle of the second seat. The vehicle obtains user information of the first user in the first image, and determines the volume of space occupied by the first user based on the user information. When the volume of space occupied by the first user is greater than or equal to a first preset value and less than a second preset value, the vehicle obtains a third angle range corresponding to the backrest angle of the second seat. When the volume of space occupied by the first user is greater than or equal to the second preset value and less than the third preset value, the vehicle obtains a fourth angle range corresponding to the backrest angle of the second seat; the third angle range is greater than the fourth angle range.

[0018] In this implementation, when the volume of space occupied by the first user is in different ranges, the restrictions on the second seat back angle by the vehicle are also different. This can fully consider the size, weight and other physical conditions of the rear users and reduce the impact of the front users adjusting their seats on the rear users.

[0019] In an implementation of the first aspect, the adjustable item includes the position of the second seat, and the adjustment restriction condition includes limiting the distance range for adjusting the position of the second seat. The vehicle obtains user information of the first user in the first image, and determines the volume of space occupied by the first user based on the user information. When the volume of space occupied by the first user is greater than or equal to a first preset value and less than a fourth preset value, the vehicle obtains a third distance range corresponding to the position of the second seat. When the volume of space occupied by the first user is greater than or equal to a fourth preset value and less than a fifth preset value, the vehicle obtains a fourth distance range corresponding to the position of the second seat; the third distance range is greater than the fourth distance range.

[0020] In this implementation, when the volume of space occupied by the first user is in different ranges, the restrictions of the vehicle on the second seat position are also different. This can fully consider the size, weight and other physical conditions of the rear users and reduce the impact of the front users adjusting their seats on the rear users.

[0021] In one implementation of the first aspect, if the second user adjusts the backrest angle of the second seat and the backrest angle of the second seat exceeds the angle range corresponding to the backrest angle of the second seat, the vehicle controls the backrest angle of the second seat to be adjusted to the angle corresponding to the maximum value of the angle range.

[0022] In one implementation of the first aspect, if the second user adjusts the position of the second seat so that the position of the second seat relative to the first seat exceeds the distance range corresponding to the position of the second seat, the vehicle controls the position of the second seat to adjust to the position corresponding to the maximum value of the distance range.

[0023] In the above two implementations, the adjustment of the front seats can be restricted according to the situation of the first user sitting in the rear seat, so as to reduce the influence of the adjustment of the front seats on the first user sitting in the rear seat. While ensuring the comfort of the second user sitting in the front seat, the riding experience of the first user sitting in the rear seat can also be taken into consideration.

[0024] In an implementation of the first aspect, the first seat information includes seat belt wearing information corresponding to the first seat; when the seat belt wearing information corresponding to the first seat indicates that the seat belt of the first seat is worn, the first seat information indicates that there is a first user on the first seat; when the seat belt wearing information corresponding to the first seat indicates that the seat belt of the first seat is not worn, the first seat information indicates that there is no user on the first seat.

[0025] In this implementation, the seat belt wearing information corresponding to the first seat can reflect whether the first seat is occupied. In addition, in addition to being used to determine whether there is a user on the seat, the seat belt wearing information can also constrain the user to use the seat belt more actively. Because, in some possible application scenarios, if there is actually a user on the back seat, but the user is not using the seat belt, the vehicle may determine that there is no user on the back seat, and will not restrict the adjustment of the front seat. If the back seat user wants to avoid this situation, he will actively use the seat belt, so that the vehicle can determine that there is a user on the back seat and restrict the adjustment of the front seat. In this way, not only can the back seat users ride more comfortably, but the safety of travel can also be improved.

[0026] In one implementation of the first aspect, when the first seat information indicates that there is no user sitting on the first seat, if the second user adjusts the adjustable item of the second seat, the vehicle controls the adjustable item to adjust to a corresponding angle or position according to the adjustment operation of the second user.

[0027] In this implementation, when the first seat information indicates that there is no user sitting on the first seat, it means that the adjustment of the adjustable item of the second seat may not affect other users. In this case, if the second user adjusts the adjustable item of the second seat, the vehicle can control the adjustable item to adjust to the corresponding angle or position according to the adjustment operation of the second user, that is, the vehicle will not restrict the adjustment operation of the second user on the second seat, thereby improving the comfort of the second user riding the vehicle and ensuring the riding experience of the second user.

[0028] In a second aspect, a vehicle is provided, which at least includes a first seat and a second seat facing the same direction, and a control unit connected to the first seat and the second seat respectively, wherein the second seat is located in the row in front of the first seat, and the second seat corresponds to at least one adjustable item. The control unit is used to: obtain the first seat information of the first seat; when the first seat information indicates that there is a first user on the first seat, obtain the adjustment restriction condition corresponding to the adjustable item of the second seat; the adjustment restriction condition is used to limit the adjustment range of the adjustable item; when the second user adjusts the adjustable item of the second seat, the adjustment operation of the second user is restricted based on the adjustment restriction condition corresponding to the adjustable item.

[0029] In an implementation of the second aspect, the first seat includes a pressure sensor, which is connected to the control unit; the first seat information includes a pressure value corresponding to the first seat. The pressure sensor is used to: obtain the pressure value corresponding to the first seat, and send the pressure value corresponding to the first seat to the control unit. The control unit is also used to: when the pressure value corresponding to the first seat is greater than or equal to the first pressure value, determine that the first seat information indicates that the first user exists on the first seat; when the pressure value corresponding to the first seat is less than the first pressure value, determine that the first seat information indicates that the user does not exist on the first seat.

[0030] In an implementation of the second aspect, the adjustable item includes a backrest angle of the second seat, and the adjustment restriction condition includes limiting the angle range of the backrest angle of the second seat. The control unit is also used to: when the pressure value corresponding to the first seat is greater than or equal to the first pressure value and less than the second pressure value, obtain the first angle range corresponding to the backrest angle of the second seat; when the pressure value corresponding to the first seat is greater than or equal to the second pressure value and less than the third pressure value, obtain the second angle range corresponding to the backrest angle of the second seat; the first angle range is greater than the second angle range.

[0031] In an implementation of the second aspect, the adjustable item includes the position of the second seat, and the adjustment restriction condition includes limiting the distance range of adjusting the position of the second seat. The control unit is further used to: when the pressure value corresponding to the first seat is greater than or equal to the first pressure value and less than the fourth pressure value, obtain the first distance range corresponding to the position of the second seat; when the pressure value corresponding to the first seat is greater than or equal to the fourth pressure value and less than the fifth pressure value, obtain the second distance range corresponding to the position of the second seat; the first distance range is greater than the second distance range.

[0032] In an implementation of the second aspect, the vehicle further includes at least one camera, and the first seat information includes a first image corresponding to the first seat. The camera is used to obtain the first image corresponding to the first seat and send the first image to the control unit. The control unit is further used to determine a first user existing on the first seat based on the first image.

[0033] In an implementation of the second aspect, the adjustable item includes the backrest angle of the second seat, and the adjustment restriction condition includes limiting the angle range of adjusting the backrest angle of the second seat. The control unit is further used to: obtain user information of the first user in the first image, and determine the space volume occupied by the first user based on the user information; when the space volume occupied by the first user is greater than or equal to the first preset value and less than the second preset value, obtain the third angle range corresponding to the backrest angle of the second seat; when the space volume occupied by the first user is greater than or equal to the second preset value and less than the third preset value, obtain the fourth angle range corresponding to the backrest angle of the second seat; the third angle range is greater than the fourth angle range.

[0034] In an implementation of the second aspect, the adjustable item includes the position of the second seat, and the adjustment restriction condition includes limiting the distance range for adjusting the position of the second seat. The control unit is also used to: obtain user information of the first user in the first image, and determine the space volume occupied by the first user based on the user information; when the space volume occupied by the first user is greater than or equal to the first preset value and less than the fourth preset value, obtain the third distance range corresponding to the position of the second seat; when the space volume occupied by the first user is greater than or equal to the fourth preset value and less than the fifth preset value, obtain the fourth distance range corresponding to the position of the second seat; the third distance range is greater than the fourth distance range.

[0035] In an implementation method of the second aspect, the control unit is also used to control the backrest angle of the second seat to be adjusted to an angle corresponding to the maximum value of the angle range if the backrest angle of the second seat exceeds the angle range corresponding to the backrest angle of the second seat after the second user adjusts the backrest angle of the second seat.

[0036] In an implementation method of the second aspect, the control unit is also used to control the position of the second seat to be adjusted to a position corresponding to the maximum value of the distance range if the position of the second seat exceeds the distance range corresponding to the position of the second seat after the second user adjusts the position of the second seat.

A person of ordinary skill in the art can appreciate that with the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0056] Seats are facilities that users need to touch for a long time when riding in public transportation. The comfort of seats affects the user experience. At present, in order to ensure that users can have a better experience when riding in vehicles, high-speed trains, airplanes and other means of transportation, the comfort of seats can usually be adjusted. Among them, there are many ways to adjust the comfort of seats, such as providing comfortable seats, providing seats with flexible adjustable functions (such as adjustable backrests, ventilation and heating, massage functions, etc.), etc.

[0057] However, for seats that provide flexible adjustment functions, the functional adjustment of each seat is completely independent. For example, adjusting the seat spacing and the seat back angle are only adjusted for the current seat. In this way, although the riding experience and comfort of the passengers on the current seat are improved, the riding space for the rear passengers will be reduced, or inconvenience will be caused to the rear passengers. It can be seen that although the current seat adjustment method can improve the riding experience of the front passengers, it affects the riding experience of the rear passengers.

[0058] Based on the above content, an embodiment of the present application provides a seat adjustment method, which adjusts the second seat of a first seat and a second seat facing the same direction, and the second seat is located in the row in front of the first seat, and the second seat corresponds to at least one adjustable item. In this method, firstly, the first seat information of the first seat is obtained, and when the first seat information indicates that there is a first user on the first seat, the adjustment restriction condition corresponding to the adjustable item of the second seat is obtained, wherein the adjustment restriction condition is used to limit the adjustment range of the adjustable item; and when the second user adjusts the adjustable item of the second seat, the adjustment operation of the second user is restricted based on the adjustment restriction condition corresponding to the adjustable item.

[0059] The above method can limit the adjustment of the front seat according to the situation of the first user sitting on the rear seat, thereby reducing the impact of the adjustment of the front seat on the first user on the rear seat. While ensuring the comfort of the second user on the front seat, the riding experience of the first user on the rear seat can also be taken into consideration.

[0060] The above-mentioned seat adjustment method in the embodiment of the present application can be applied to vehicles such as cars, buses, high-speed trains, and airplanes that include at least two vertically arranged adjustable seats, wherein the orientations of the vertically arranged adjustable seats are also the same.

[0061] See also Figure 1 As shown, the vehicle may include seat 1, seat 2, ... seat N, and a control unit 101 connected to each seat. Among them, seats 1-seat N are arranged vertically and face the same direction. The control unit 101 can obtain the seat information of each seat respectively, and determine whether there is a first user sitting on the rear seat according to the seat information of the rear seat, and determine the adjustment restriction condition of the adjustable item of the front seat when there is a user sitting on the rear seat. When the second user adjusts an adjustable item of the front seat, the control unit 101 can restrict the adjustment operation of the second user based on the adjustment restriction condition corresponding to the adjustable item.

[0062] The seat information may include a pressure value corresponding to the seat, an image corresponding to the seat, seat belt wearing information corresponding to the seat, etc. In some possible application scenarios, the control unit 101 may determine whether there is a user on the seat according to the pressure value corresponding to the seat, for example, when the pressure value is greater than or equal to the first pressure value, it is determined that there is a user, and when the pressure value is less than the first pressure value, it is determined that there is no user; or, the control unit 101 may also determine whether there is a user on the seat according to the image corresponding to the seat, for example, by identifying the content in the image, when the image includes the user, it is determined that there is a user, and when the image does not include the user, it is determined that there is no user; or, the control unit 101 may also determine whether there is a user on the seat according to the seat belt wearing information, for example, when the seat belt wearing information indicates that the seat belt of the seat is worn, it is determined that there is a user, and when the seat belt wearing information indicates that the seat belt of the seat is not worn, it is determined that there is no user.

[0063] In some other possible application scenarios, the control unit 101 may also determine whether there is a user on the seat by combining any two or all three of the pressure value, image, and seat belt wearing information corresponding to the seat. For example, when the seat belt wearing information indicates that the seat belt is not worn, it is further determined whether there is a user based on the pressure value or image corresponding to the seat; or, when the image corresponding to the seat includes a user, it is further determined whether there is a user based on the pressure value corresponding to the seat (the user here refers to a user who can affect the adjustment range of the second seat).

[0064] The above-mentioned seat adjustable items may include seat position, seat back angle, etc., and the adjustment restriction conditions of the adjustable items are used to limit the adjustment range of the adjustable items. When there is a user on the rear seat, the control unit 101 may obtain the adjustment restriction conditions corresponding to the seat position, such as obtaining the limited distance range between the front seat and the rear seat; or the control unit 101 may also obtain the adjustment restriction conditions corresponding to the seat back angle, such as obtaining the limited angle range of the front seat back, etc.; or the control unit 101 may also simultaneously obtain the adjustment restriction conditions corresponding to the seat position and the adjustment restriction conditions corresponding to the seat back angle.

[0065] For example, Figure 1The middle seat 1 is the front seat, and the seat 2 is the back seat. The control unit 101 determines whether there is a first user on the seat 2 according to the seat information of the seat 2. If there is, the adjustment restriction condition that restricts the adjustment of the seat 1 is obtained. When the second user adjusts the backrest angle of the seat 1, the control unit 101 can restrict the backrest angle of the seat 1 adjusted by the second user to a certain angle range based on the adjustment restriction condition of the backrest angle of the seat 1. When the second user adjusts the position of the seat 1, the control unit 101 can restrict the second user from adjusting the position of the seat 1 based on the adjustment restriction condition of the position of the seat 1, thereby limiting the position adjustment range of the seat 1 to a certain distance range. In this way, while ensuring the comfort of the second user corresponding to the seat 1, a certain space is also left for the first user on the seat 2 to ensure the riding experience of the first user on the seat 2.

[0066] In some possible application scenarios, the above-mentioned transportation tool may also include one or more of a pressure sensor, a camera, a seat belt detection unit, an infrared sensor, etc. Among them, a pressure sensor may be respectively provided on each seat, and the pressure sensor may detect the pressure value borne by the seat and send the corresponding pressure value of the seat to the control unit 101, so that the control unit 101 determines whether there is a user on the rear seat according to the corresponding pressure value of the seat.

[0067] Multiple cameras may be provided in the vehicle compartment, and each camera may obtain seat images of multiple different seats respectively, and send the seat images to the control unit 101, so that the control unit 101 determines whether there is a user in the rear seat according to the seat images. Alternatively, a camera may be provided for each seat in the vehicle compartment, and each camera may obtain a seat image of a seat corresponding to the seat, and send the seat image to the control unit 101, so that the control unit 101 determines whether there is a user in the rear seat according to the seat images.

[0068] A seat belt detection unit may also be provided on each seat, each of which may detect the wearing status of the seat belt on the seat and send the seat belt wearing status to the control unit 101 in the form of seat belt wearing information, so that the control unit 101 determines whether there is a user in the rear seat based on the seat belt wearing information.

[0069] An infrared sensor can also be set on each seat, and each infrared sensor can detect whether there is a user in the back seat.

[0070] In some possible application scenarios, the control unit 101 may limit the adjustment range of the adjustable items of the front seats in steps according to the weight of the user on the rear seats, the occupied space volume, etc.

[0071] Exemplarily, when there is a user on the rear seat, it is further determined whether the pressure value corresponding to the rear seat is less than the second pressure value when it is greater than or equal to the first pressure value. If the pressure value corresponding to the rear seat is less than the second pressure value, the adjustable items of the front seat can be restricted by a first gradient, that is, the first angle range corresponding to the backrest angle of the front seat is obtained, or the first distance range corresponding to the position of the front seat is obtained. If the pressure value corresponding to the rear seat is greater than or equal to the second pressure value, it can be further determined whether the pressure value corresponding to the rear seat is less than a third pressure value. If the pressure value corresponding to the rear seat is less than the third pressure value, the adjustable items of the front seat can be restricted by a second gradient, that is, the second angle range corresponding to the backrest angle of the front seat is obtained, or the second distance range corresponding to the position of the front seat is obtained. Among them, the first angle range is greater than the second angle range, and the first distance range is greater than the second distance range, indicating that the restriction degree of the first gradient is less than the restriction degree of the second gradient.

[0072] In addition, when the pressure value of the rear seat is greater than or equal to the third pressure value, the adjustable items of the front seat can be restricted by a third gradient, such as prohibiting the adjustment of the backrest angle or position of the front seat, so as to ensure the comfort of the user in the rear seat when the user in the rear seat is heavier.

[0073] As another example, when there is a user on the rear seat, the space volume occupied by the user is further determined based on the image corresponding to the rear seat. When the space volume occupied by the user is greater than or equal to the first preset value and less than the second preset value, the adjustable items of the front seat can be restricted by a first gradient, that is, the third angle range corresponding to the backrest angle of the front seat is obtained, or the third distance range corresponding to the position of the front seat is obtained. If the space volume occupied by the user is greater than or equal to the second preset value and less than the third preset value, the adjustable items of the front seat can be restricted by a second gradient, that is, the fourth angle range corresponding to the backrest angle of the front seat is obtained, or the fourth distance range corresponding to the position of the front seat is obtained. The third angle range is greater than the fourth angle range, and the third distance range is greater than the fourth distance range, indicating that the restriction degree of the first gradient is less than the restriction degree of the second gradient.

[0074] In addition, when the space occupied by the user of the rear seat is greater than or equal to the third preset value, the adjustable items of the front seat can be restricted by a third gradient, such as prohibiting the adjustment of the backrest angle or position of the front seat. Thus, when the space occupied by the user of the rear seat is large, the comfort of the user of the rear seat is guaranteed.

[0075] The control unit 101 limits the user adjustment operation on the front seat, which may include: after the user on the front seat adjusts the backrest angle of the front seat, if the backrest angle of the front seat exceeds the angle range corresponding to the backrest angle of the front seat (such as the first angle range, the second angle range, the third angle range, the fourth angle range, etc.), then the backrest angle of the front seat is controlled to be adjusted to the angle corresponding to the maximum value of the angle range. After the user on the front seat adjusts the position of the front seat, if the position of the front seat exceeds the distance range corresponding to the position of the front seat (such as the first distance range, the second distance range, the third distance range, the fourth distance range, etc.), then the control unit 101 controls the position of the front seat to be adjusted to the position corresponding to the maximum value of the distance range. Thus, the control unit 101 can achieve the purpose of limiting the adjustment of the front seat according to the angle range or the distance range, and prevent the backrest angle of the front seat from exceeding the limit and / or the position of the front seat from exceeding the limit.

[0076] It is understandable that the "rear seats" mentioned above may include any Figure 1 Any seat other than the seat 1 shown in . And, the front row seat and the rear row seat are relative, for example, seat 2 is a rear row seat relative to seat 1, and is a front row seat relative to seat 3.

[0077] For other possible application scenarios, see Figure 2 As shown, the above-mentioned vehicle may include a seat information detection unit 201 , a control unit 101 , a seat adjustment unit 202 , etc. Moreover, the seat information detection unit 201 and the seat adjustment unit 202 are connected to the control unit 101 , respectively.

[0078] Among them, the seat information detection unit 201 may include one or more of the pressure sensor, camera, seat belt detection unit, etc. in the aforementioned embodiments. The seat information detection unit 201 can obtain seat information such as pressure value, image, seat belt wearing information corresponding to each seat, and send the seat information to the control unit 101.

[0079] The control unit 101 determines whether there is a user on the rear seat based on the received seat information, and when there is a user on the rear seat, determines the adjustment restriction conditions corresponding to the adjustable items of the front seat, and can send the adjustment restriction conditions to the seat adjustment unit 202 of the front seat in the form of a control instruction.

[0080] Each seat is provided with a seat adjustment unit 202. The seat adjustment unit 202 can respond to the received control instruction and, when a user adjusts the adjustable items of the front seat, restrict the user's adjustment operation according to the adjustment restriction condition. For example, the seat adjustment unit 202 can restrict the user from adjusting the backrest angle of the front seat, restrict the user from adjusting the position of the front seat, etc.

[0081] For example, the control unit 101 may be a low-cost microcontroller unit (MCU), and may be connected to the seat information detection unit 201 and the seat adjustment unit 202 via interfaces such as CAN / RS485, so as to obtain seat information from the seat detection unit 201 and send adjustment restriction conditions to the seat adjustment unit 202. Alternatively, the control unit 101 may also be other types of control devices, which are not specifically limited in the embodiments of the present application.

[0082] In addition, when there are no users sitting in the back seats, the control unit 101 will not restrict the adjustment operations of the users of the front seats. When the users of the front seats adjust the adjustable items of the front seats, the control unit 101 can control the adjustable items to be adjusted to the corresponding angles or positions according to the adjustment operations of the users of the front seats.

[0083] In some possible application scenarios, the connection between the control unit and the seat information detection unit and the seat adjustment unit may adopt a centralized architecture or a distributed architecture.

[0084] For example, see Figure 3 As shown, the connection between the control unit and the seat information detection unit and the seat adjustment unit adopts a centralized architecture. Furthermore, a control unit can be installed on the vehicle. For example, each seat on the vehicle (such as seat 1, seat 2, seat 3, seat 4...seat N, seat N+1) includes a seat information detection unit and a seat adjustment unit, and the control unit is respectively connected to the seat information detection unit and the seat adjustment unit of each seat.

[0085] The control unit receives the seat information sent by each seat information detection unit, and determines whether there is a user on the corresponding seat according to the seat information. When there is a user on a certain seat, the control unit determines the adjustment restriction conditions corresponding to the adjustable items of the front seat of the seat, and sends the adjustment restriction conditions to the seat adjustment unit of the front seat in the form of a control instruction. For example, when Figure 3 When there is a user on the middle seat 2 , the control unit may send a control instruction corresponding to the adjustment restriction condition to the seat adjustment unit of the front seat 1 of the seat 2 .

[0086] For further example, see Figure 4 As shown, the connection between the control unit and the seat information detection unit and the seat adjustment unit adopts a distributed architecture. Furthermore, multiple control units can be installed on a vehicle, and the control units can communicate with each other. For example, each seat on a vehicle includes a seat information detection unit and a seat adjustment unit, and each control unit can be connected to the seat information detection unit and the seat adjustment unit of a part of the seats. For example, Figure 4 The control unit 1 can be connected to the seat information detection unit and the seat adjustment unit of seat 1, seat 2, and seat 3, while the control unit 2 can be connected to the seat information detection unit and the seat adjustment unit of seat 4, seat 5, and seat 6.

[0087] The control unit 1 receives the seat information of seat 1 sent by the seat information detection unit of seat 1, receives the seat information of seat 2 sent by the seat information detection unit of seat 2, and receives the seat information of seat 3 sent by the seat information detection unit of seat 3. And, according to the seat information, it is determined whether there is a user on the corresponding seat, and if so, a control instruction corresponding to the adjustment restriction condition is sent to the seat adjustment unit of the front seat of the seat. For example, if the control unit 1 determines that there is a user on the seat according to the seat information of seat 2, it sends a control instruction corresponding to the adjustment restriction condition to the seat adjustment unit of the front seat 1 of seat 2.

[0088] The control unit 2 receives the seat information of seat 4 sent by the seat information detection unit of seat 4, receives the seat information of seat 5 sent by the seat information detection unit of seat 5, and receives the seat information of seat 6 sent by the seat information detection unit of seat 6. And, according to the seat information, it is determined whether there is a user on the corresponding seat, and if so, a control instruction corresponding to the adjustment restriction condition is sent to the seat adjustment unit of the front seat of the seat. For example, if the control unit 2 determines that there is a user on the seat according to the seat information of seat 5, it sends a control instruction corresponding to the adjustment restriction condition to the seat adjustment unit of the front seat 4 of seat 5.

[0089] Furthermore, if there is a user on seat 4, the control unit 2 can also communicate with the control unit 1 and send the adjustment restriction conditions of the front seat 3 of seat 4 to the control unit 1, so that the control unit 1 can send control instructions corresponding to the adjustment restriction conditions to the seat adjustment unit of seat 3.

[0090] As another example, no matter which of the above connection modes is used, the control unit can communicate with the seat information detection unit and the seat adjustment unit through the data communication module.

[0091] The above-mentioned seat adjustment method is applied to a vehicle. When a user rides in the vehicle, he can adjust the backrest angle or position of the current seat according to his own needs. If there are other users sitting in the back seats at this time, the user in the front seat will be restricted in adjusting his own seat. This can reduce the impact of the front seat adjustment on the users in the back seats while meeting the needs and comfort of the users in the front seats as much as possible.

[0092] See also Figure 5 As shown, the seat adjustment method may include the following steps S501-S503.

[0093] S501: A vehicle obtains first seat information of a first seat.

[0094] The vehicle at least includes a first seat and a second seat, and the second seat is located in a row in front of the first seat. Also, the first seat can be represented as a rear seat, and the second seat can be represented as a front seat.

[0095] In some embodiments, the first seat information includes one or more of a pressure value corresponding to the first seat, a first image corresponding to the first seat, and seat belt wearing information corresponding to the first seat.

[0096] Exemplarily, the vehicle can obtain a pressure value corresponding to the first seat through a pressure sensor corresponding to the first seat, obtain a first image corresponding to the first seat through a camera corresponding to the first seat, and obtain seat belt wearing information corresponding to the first seat through a seat belt detection unit corresponding to the first seat.

[0097] In some embodiments, the first seat information may indicate whether there is a first user in the first seat.

[0098] The pressure value corresponding to the first seat can reflect whether the first seat is occupied and the weight of the first user. When the pressure value corresponding to the first seat is greater than or equal to the first pressure value, the first seat information can indicate that there is a first user on the first seat, and when the pressure value corresponding to the first seat is less than the first pressure value, the first seat information can indicate that there is no user on the first seat, or the effect of the adjustment of the second seat on the existing first user can be ignored (such as a child sitting on the first seat, etc.). The first pressure value represents a preset pressure value, such as 35KG, 40KG (i.e., based on 40kg in the seat belt test standard GB / T 24551), etc., that is, when the pressure value corresponding to the first seat is greater than or equal to the first pressure value, the effect of the adjustment of the second seat on the first user can be considered.

[0099] The content included in the first image may reflect whether the first seat is occupied and the volume of space occupied by the first user who is seated there.

[0100] See also Figure 6 As shown, when the first image contains the image of the first user, the first image may indicate that the first user is on the first seat. The first image may also include the image of the first seat, thereby making it easier to determine whether the first user is on the first seat.

[0101] The seat belt wearing information corresponding to the first seat can reflect whether the first seat is occupied. When the seat belt wearing information corresponding to the first seat indicates that the seat belt of the first seat is worn, the first seat information can indicate that there is a first user on the first seat; when the seat belt wearing information corresponding to the first seat indicates that the seat belt of the first seat is not worn, the first seat information can indicate that there is no user on the first seat.

[0102] In some possible application scenarios, the vehicle may determine whether the first user is in the first seat according to any of the first seat information. In other possible application scenarios, the vehicle may also determine whether the first user is in the first seat according to any two or all of the first seat information.

[0103] Exemplarily, the vehicle may first determine whether the pressure value corresponding to the first seat is greater than or equal to the first pressure value, and when the pressure value corresponding to the first seat is greater than or equal to the first pressure value, further determine whether the seat belt wearing information corresponding to the first seat indicates that the seat belt of the first seat is worn. If the seat belt wearing information indicates that the seat belt of the first seat is worn, the vehicle may determine that the first user exists on the first seat, and at the same time, the first seat information also indicates that the first user exists on the first seat. In this way, it is possible to determine whether the first user exists from the two aspects of the pressure value and the seat belt wearing, thereby improving the accuracy of determining the first user.

[0104] S502: When the first seat information indicates that there is a first user on the first seat, the vehicle obtains an adjustment restriction condition corresponding to an adjustable item of the second seat.

[0105] Among them, the adjustable items include the backrest angle of the second seat, the position of the second seat, etc., and the adjustment restriction conditions are used to limit the adjustment range of the adjustable items. That is to say, the adjustment restriction conditions may include limiting the angle range for adjusting the backrest angle of the second seat, and may also include limiting the distance range for adjusting the position of the second seat.

[0106] In some embodiments, when the adjustment restriction condition includes limiting the angle range of adjusting the backrest angle of the second seat, the adjustment restriction condition may also be the weight of the first user, the space volume occupied, etc., and different weights and / or occupied space volumes correspond to different restricted angle ranges. Furthermore, the vehicle may obtain different restricted angle ranges in the adjustment restriction condition under different circumstances.

[0107] Exemplarily, when the pressure value corresponding to the first seat is greater than or equal to the first pressure value and less than the second pressure value, the vehicle obtains the first angle range corresponding to the backrest angle of the second seat. When the pressure value corresponding to the first seat is greater than or equal to the second pressure value and less than the third pressure value, the vehicle obtains the second angle range corresponding to the backrest angle of the second seat.

[0108] When the pressure value corresponding to the first seat is greater than or equal to the first pressure value and less than the second pressure value, it means that the first user on the first seat has a small weight and may be a thin person. In this case, the restriction on the backrest angle of the second seat can be relaxed, so that the first angle range is larger. Figure 7 As shown in (a), the position of the seat back indicated by the solid line represents the initial position of the backrest angle, and the position of the seat back indicated by the dotted line represents the adjusted position of the backrest angle. When the pressure value corresponding to the first seat is greater than or equal to the second pressure value and less than the third pressure value, it means that the first user on the first seat is heavier, and may be a slightly fat or slightly fat person, then the restriction on the second seat backrest angle needs to be stricter, and thus the second angle range is smaller than the first angle range, see Figure 7 As shown in (b) in FIG. 1 , the first pressure value, the second pressure value, the third pressure value, etc. all represent preset pressure values, and the second pressure value can be 60KG, 65KG, 70KG, etc., and the third pressure value can be 80KG, 85KG, etc.

[0109] It can be seen that when the pressure value corresponding to the first seat is in different ranges, the restrictions on the second seat back angle of the vehicle are also different. This can fully consider the weight, fatness and other physical conditions of the rear users and reduce the impact of the front users on the rear users when adjusting their seats.

[0110] In some possible application scenarios, when the pressure value corresponding to the first seat is greater than or equal to the third pressure value, it may indicate that the weight of the first user on the first seat is particularly large. In order to ensure that the adjustment of the second seat does not affect the first user on the first seat, the second user on the second seat may be prohibited from adjusting the backrest angle of the second seat.

[0111] As another example, the vehicle may also obtain user information of the first user in the first image corresponding to the first seat, and determine the volume of space occupied by the first user based on the user information. When the volume of space occupied by the first user is greater than or equal to the first preset value and less than the second preset value, the vehicle obtains a third angle range corresponding to the backrest angle of the second seat. When the volume of space occupied by the first user is greater than or equal to the second preset value and less than the third preset value, the vehicle obtains a fourth angle range corresponding to the backrest angle of the second seat.

[0112] When the space volume occupied by the first user is greater than or equal to the first preset value and less than the second preset value, it means that the first user is small in size and may be a thin person, so the restriction on the second seat back angle can be relaxed, and the third angle range is larger. When the space volume occupied by the first user is greater than or equal to the second preset value and less than the third preset value, it means that the first user is large in size and may be a slightly fat or slightly fat person, so the restriction on the second seat back angle needs to be stricter, and the fourth angle range is smaller than the third angle range.

[0113] In some possible application scenarios, the third angle range may be the same as the first angle range described above, and the fourth angle range may be the same as the second angle range described above. This embodiment of the present application does not impose any specific limitation on this.

[0114] It can be seen that when the volume of space occupied by the first user is in different ranges, the restrictions of the vehicle on the angle of the second seat backrest are also different. This can fully consider the size, fatness and other physical conditions of the rear users, and reduce the impact of the front users on the rear users when adjusting their seats.

[0115] In some possible application scenarios, when the volume of the space occupied by the first user is greater than or equal to a third preset value, it may indicate that the volume of the first user is particularly large. In order to ensure that the adjustment of the second seat does not affect the first user, the second user on the second seat may be prohibited from adjusting the backrest angle of the second seat.

[0116] In other embodiments, when the adjustment restriction condition includes limiting the distance range of adjusting the position of the second seat, the adjustment restriction condition can also be configured with a corresponding limited distance range for the weight of the first user, the space volume occupied, etc., and different weights and / or space volumes occupied correspond to different limited distance ranges. Furthermore, the vehicle can obtain different limited distance ranges in the adjustment restriction condition under different circumstances.

[0117] Exemplarily, when the pressure value corresponding to the first seat is greater than or equal to the first pressure value and less than the fourth pressure value, the vehicle obtains the first distance range corresponding to the position of the second seat. When the pressure value corresponding to the first seat is greater than or equal to the fourth pressure value and less than the fifth pressure value, the vehicle obtains the second distance range corresponding to the position of the second seat.

[0118] When the pressure value corresponding to the first seat is greater than or equal to the first pressure value and less than the fourth pressure value, it means that the first user on the first seat has a small weight and may be a thin person. In this case, the restriction on the second seat position can be relaxed, and the first distance range is larger. Figure 8 As shown in (a), the position of the seat indicated by the solid line represents the initial position of the seat, and the position of the seat indicated by the dotted line represents the adjusted position of the seat. When the pressure value corresponding to the first seat is greater than or equal to the fourth pressure value and less than the fifth pressure value, it means that the first user on the first seat is heavier, and may be a slightly fat or slightly fat person, then the restriction on the second seat position needs to be stricter, and thus the second distance range is smaller than the first distance range, see Figure 8 As shown in (b) in .

[0119] In some possible application scenarios, the fourth pressure value may be the same as the second pressure value, and the fifth pressure value may be the same as the third pressure value, which is not specifically limited in the embodiments of the present application.

[0120] It can be seen that when the pressure value corresponding to the first seat is in different ranges, the restrictions of the vehicle on the second seat position are also different. This can fully consider the weight, fatness and other physical conditions of the rear users and reduce the impact of the front users on the rear users when adjusting their seats.

[0121] In some possible application scenarios, when the pressure value corresponding to the first seat is greater than or equal to the fifth pressure value, it may indicate that the weight of the first user on the first seat is particularly large. In order to ensure that the adjustment of the second seat does not affect the first user on the first seat, the second user on the second seat may be prohibited from adjusting the position of the second seat.

[0122] As another example, the vehicle may also obtain user information of the first user in the first image, and determine the space volume occupied by the first user based on the user information. When the space volume occupied by the first user is greater than or equal to the first preset value and less than the fourth preset value, the third distance range corresponding to the position of the second seat is obtained. When the space volume occupied by the first user is greater than or equal to the fourth preset value and less than the fifth preset value, the fourth distance range corresponding to the position of the second seat is obtained.

[0123] When the space volume occupied by the first user is greater than or equal to the first preset value and less than the fourth preset value, it means that the first user is small and may be a thin person, so the restriction on the second seat position can be relaxed, and the third distance range is larger. When the space volume occupied by the first user is greater than or equal to the fourth preset value and less than the fifth preset value, it means that the first user is large and may be a slightly fat or slightly fat person, so the restriction on the second seat position needs to be stricter, and the fourth distance range is smaller than the third distance range.

[0124] In some possible application scenarios, the fourth preset value may be the same as the second preset value, and the fifth preset value may be the same as the third preset value. Also, the third distance range may be the same as the first distance range, and the fourth distance range may be the same as the second distance range. This is not specifically limited in the embodiments of the present application.

[0125] It can be seen that when the volume of space occupied by the first user is in different ranges, the restrictions of the vehicle on the second seat position are also different. This can fully consider the size, fatness and other physical conditions of the rear users and reduce the impact of the front users adjusting their seats on the rear users.

[0126] In some possible application scenarios, when the volume of the space occupied by the first user is greater than or equal to the fifth preset value, it may indicate that the volume of the first user is particularly large. In order to ensure that the adjustment of the second seat does not affect the first user, the second user on the second seat may be prohibited from adjusting the position of the second seat.

[0127] In addition, it can be understood that the first pressure value, second pressure value, third pressure value, fourth pressure value, fifth pressure value, first preset value, second preset value, third preset value, fourth preset value, fifth preset value, etc. in the embodiments of the present application are all preset, and the specific values ​​are determined according to the actual conditions of the vehicle and / or the passengers. The specific values ​​of the above-mentioned preset values ​​are not specifically limited in the embodiments of the present application.

[0128] S503: When the second user adjusts the adjustable item of the second seat, the vehicle restricts the adjustment operation of the second user based on the adjustment restriction condition corresponding to the adjustable item.

[0129] The restriction of the adjustment operation of the second user by the vehicle means that the backrest angle of the second seat is restricted to not exceed the corresponding angle range, and / or the position of the second seat is restricted to not exceed the distance range corresponding to the second seat.

[0130] For example, if the backrest angle of the second seat exceeds the angle range corresponding to the backrest angle of the second seat after the second user adjusts the backrest angle of the second seat, the vehicle controls the backrest angle of the second seat to be adjusted to the angle corresponding to the maximum value of the angle range. For example, the angle range corresponding to the backrest angle of the second seat is 90-100°. If the backrest angle of the second seat changes from 90° to 105° or from 95° to 105° after the second user adjusts the backrest angle, which will cause the backrest angle to exceed the limit of the angle range, the vehicle will control the backrest angle of the second seat to be 100° in the end.

[0131] For another example, if the second user adjusts the position of the second seat so that the position of the second seat exceeds the distance range corresponding to the position of the second seat, the vehicle controls the position of the second seat to be adjusted to the position corresponding to the maximum value of the distance range. For example, the distance range corresponding to the position of the second seat is 0-0.2m (the range that can be adjusted backward from the initial position). If the position of the second seat is adjusted by the second user, it will change from the position of 0m (i.e., the initial position) to the position of 0.3m, or from the position of 0.1m to the position of 0.3m, which will make the seat position exceed the limit of the corresponding distance range, then the vehicle will control the position of the second seat to finally be at the position of 0.2m.

[0132] As can be seen from the above content, the seat adjustment method provided in the embodiment of the present application can restrict the adjustment of the front seat according to the situation of the first user sitting in the rear seat, thereby reducing the impact of the adjustment of the front seat on the first user in the rear seat. While ensuring the comfort of the second user in the front seat, the riding experience of the first user in the rear seat can also be taken into consideration.

[0133] In some embodiments, when the first seat information indicates that there is no user sitting on the first seat, it means that the adjustment of the adjustable item of the second seat may not affect other users. In this case, if the second user adjusts the adjustable item of the second seat, the vehicle can control the adjustable item to adjust to the corresponding angle or position according to the adjustment operation of the second user, that is, the vehicle will not restrict the adjustment operation of the second user on the second seat, thereby improving the comfort of the second user riding the vehicle and ensuring the riding experience of the second user.

[0134] It is understandable that the backrest angle and position of the seat in the embodiment of the present application each have their own initial positions. When the user adjusts the adjustable items of the seat, the backrest of the seat can be adjusted from the initial position, or the backrest of the seat can be adjusted from the current position. Exemplarily, the initial position of the seat backrest can be a position where the backrest can be 90° to the seat cushion, and the backrest angle of the seat can refer to the angle between the backrest and the seat cushion. Also, when the user adjusts the adjustable items of the seat, the seat can be adjusted from the initial position, or the seat can be adjusted from the current position.

[0135] For example, the angle range for limiting the adjustment of the backrest angle in the embodiment of the present application refers to Figure 7 The angle range of the seat backrest shown in (a) is greater than 90°, and the distance range for limiting the seat position adjustment is from Figure 8 (a) shows the distance range of the seat from the initial position to the rear seat.

[0136] In some embodiments, the above-mentioned vehicle may also first determine a restriction strategy for the adjustable items of the second seat in combination with the pressure value corresponding to the first seat and the seat belt wearing information. Then, the weight and volume of the first user are determined based on the pressure value of the first seat and / or the first image, so as to obtain adjustment restriction conditions under the corresponding restriction strategy, such as a restricted angle range and / or a restricted distance range.

[0137] For example, see Fig. 9 As shown, the vehicle determines that there is a first user in the first seat according to the pressure value corresponding to the first seat, and then the vehicle continues to determine whether the seat belt of the first seat is used according to the seat belt wearing information. If the seat belt is not used, the restriction strategy determined by the vehicle is to restrict the adjustment of the adjustable item of the second seat to a certain extent. If the seat belt is used, the restriction strategy determined by the vehicle is not to allow the adjustment of the adjustable item of the second seat, or to restrict the adjustment of the adjustable item of the second seat to a greater extent.

[0138] Afterwards, the vehicle further determines the restricted angle ranges under different restriction strategies based on the pressure value and / or the first image corresponding to the first seat, such as the first angle range, the second angle range, etc. in the above embodiments, and determines the restricted distance ranges under different restriction strategies, such as the first distance range, the second distance range, etc. in the above embodiments.

[0139] In some embodiments, the aforementioned seat belt wearing information can not only be used to determine whether there is a user on the seat, but also to constrain the user to use the seat belt more actively. Because, in some possible application scenarios, if there is actually a user on the rear seat, but the user does not use the seat belt, then the vehicle may determine that there is no user on the rear seat, and then will not restrict the adjustment of the front seat. If the rear user wants to avoid this situation, he will actively use the seat belt, so that the vehicle can determine that there is a user on the rear seat and restrict the adjustment of the front seat. In this way, not only can the rear users ride more comfortably, but also the safety of travel can be improved.

[0140] In some possible application scenarios, the above-mentioned vehicle can trigger the operation of obtaining the first seat information each time it is ignited or started, and determine whether there is a first user on the first seat based on the first seat information, and whether to obtain the adjustment restriction conditions corresponding to the adjustable items of the second seat.

[0141] When the vehicle obtains the adjustment restriction condition of the second seat, the adjustment restriction condition may be sent to the seat adjustment unit of the second seat. The seat adjustment unit may determine whether to restrict the adjustment operation of the adjustable item of the second seat or the adjustment operation of the second user according to the sitting condition of the second user on the second seat.

[0142] For example, see Fig.10 As shown, after the seat adjustment unit receives the adjustment restriction condition, if there is no user sitting on the second seat, the adjustment restriction condition takes effect immediately. Thereafter, if there is a user adjusting the adjustable item of the second seat, the seat adjustment unit will impose restrictions according to the adjustment restriction condition.

[0143] After the seat adjustment unit receives the adjustment restriction condition, if there is a user sitting on the second seat, the adjustment restriction condition will not take effect, and the seat adjustment unit will not force the second seat to adjust the adjustable items that have been adjusted to meet the requirements of the adjustment restriction condition, so as to avoid negative impact on the user sitting on the second seat. Afterwards, if the user sitting on the second seat stands up or readjusts the second seat, the adjustment restriction condition will take effect, and the seat adjustment unit will impose restrictions according to the adjustment restriction condition.

[0144] In other possible application scenarios, the vehicle can also obtain the first seat information in real time, so as to promptly determine whether there is a first user on the first seat, and promptly obtain the adjustment restriction conditions corresponding to the adjustable items of the second seat, so as to more flexibly limit the adjustment of the adjustable items of the second seat in time according to the sitting conditions of the first user on the first seat, the weight of the first user, the volume of the first user, etc.

[0145] Exemplarily, the vehicle obtains the first seat information in real time. If the first seat information obtained for the first time indicates that there is no user on the first seat, in this case, the vehicle may not restrict the adjustment of the second seat. Afterwards, if the first user is sitting on the first seat, the vehicle will determine that there is the first user on the first seat based on the first seat information obtained at this time, and then start to restrict the adjustment of the second seat according to the method of the above embodiment. If the first user sitting on the first seat changes, since the weight and volume of the two may be different, the vehicle can also change the restricted angle range and / or restricted distance range of the second seat based on the pressure value, the first image, etc. in the first seat information.

[0146] It is understandable that in the embodiments of the present application, the collection, storage, use, processing, transmission, provision and disclosure of user information involved are in compliance with the provisions of relevant laws and regulations and do not violate public order and good morals.
