Description

Seat adjustment method and transportation

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on September 11, 2023, with application number 202311170407.4 and application name “Seat Adjustment Method and Vehicle”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of artificial intelligence technology, and in particular to a seat adjustment method and a vehicle. Background Art

[0003] Currently, to ensure passenger comfort in cars, buses, high-speed trains, airplanes, and other modes of transportation, seat comfort can often be adjusted. There are many ways to adjust seat comfort, such as providing comfortably shaped seats and seats with flexible adjustable functions (e.g., adjustable backrests, ventilation and heating, massage functions, etc.).

[0004] However, the adjustment functions of some seats, such as adjusting the seat pitch and seat back angle, while improving the riding experience and comfort of the passengers in the seat, will result in a reduction in the riding space for rear passengers. This can improve the riding experience of front passengers but affect the riding experience of rear passengers.

[0005] Summary of the Invention

[0006] The present application provides a seat adjustment method and a vehicle, which can ensure the comfort of a second user in the front seat while also taking into account the riding experience of a first user in the rear seat.

[0007] To achieve the above objectives, this application adopts the following technical solutions:

[0008] In a first aspect, a seat adjustment method is provided, which is applied to a vehicle, wherein the vehicle includes 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.

[0009] The method includes: a vehicle obtains first seat information of a first seat; when the first seat information indicates that a first user is present 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.

[0010] The above method can limit 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 front seat adjustment 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.

[0011] In one implementation 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.

[0012] 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 in the first seat. When the pressure value corresponding to the first seat is less than the first pressure value, the first seat information can indicate that no user is in the first seat, or the effect of the adjustment of the second seat on the presence of the first user can be ignored (for example, if a child is in the first seat).

[0013] In one implementation of the first aspect, the adjustable item includes a backrest angle of a second seat, and the adjustment restriction condition includes limiting the angular range of adjustment for the backrest angle of the second seat. When the pressure value corresponding to the first seat is greater than or equal to a first pressure value and less than a second pressure value, the vehicle acquires a first angular 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 a third pressure value, the vehicle acquires a second angular range corresponding to the backrest angle of the second seat; the first angular range is greater than the second angular range.

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

[0015] In one implementation of the first aspect, the adjustable item includes the position of a second seat, and the adjustment restriction condition includes limiting the distance range within which the second seat's position can be adjusted. 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 a first distance range corresponding to the second seat's position. 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 a second distance range corresponding to the second seat's position; the first distance range is greater than the second distance range.

[0016] In this implementation, when the pressure value corresponding to the first seat is in different ranges, the vehicle's restrictions 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 on the rear users when the front users adjust their seats.

[0017] 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.

[0018] In this implementation, 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.

[0019] In one implementation of the first aspect, the adjustable item includes the backrest angle of the second seat, and the adjustment restriction condition includes limiting the angular range of adjustment of the backrest angle of the second seat. The vehicle obtains user information of the first user in the first image and, based on the user information, determines the volume of the space occupied by the first user. When the volume of the 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 angular range corresponding to the backrest angle of the second seat. When the volume of the 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 angular range corresponding to the backrest angle of the second seat; the third angular range is greater than the fourth angular range.

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

[0021] In one implementation of the first aspect, the adjustable item includes the position of the second seat, and the adjustment restriction includes a distance range limiting the adjustment of the second seat's position. The vehicle obtains user information of the first user in the first image and, based on the user information, determines the volume of space occupied by the first user. 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.

[0022] In this implementation, when the space volume 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 on the rear users when the front users adjust their seats.

[0023] In one implementation method 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.

[0024] 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 be adjusted to the position corresponding to the maximum value of the distance range.

[0025] In the two aforementioned implementations, front seat adjustments can be restricted based on the first user's situation, reducing the impact of front seat adjustments on the first user in the rear seat. While ensuring the comfort of the second user in the front seat, the first user's riding experience in the rear seat can also be taken into consideration.

[0026] In one 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.

[0027] In this implementation, the seatbelt wearing information corresponding to the first seat can indicate whether the first seat is occupied. Furthermore, in addition to determining whether a user is currently seated, this seatbelt wearing information can also encourage users to actively use their seatbelts. In some potential scenarios, if a user is actually in the rear seat but not wearing a seatbelt, the vehicle may determine that no one is in the rear seat and, therefore, not restrict front seat adjustments. To avoid this, the rear seat user may actively use their seatbelt, allowing the vehicle to detect the presence of a user and restrict front seat adjustments. This not only allows rear seat users to ride more comfortably but also improves travel safety.

[0028] 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 be adjusted to a corresponding angle or position according to the adjustment operation of the second user.

[0029] In this implementation, if the first seat information indicates that no user is seated in the first seat, adjustments to the adjustable items of the second seat may not affect other users. In this case, if the second user adjusts the adjustable items of the second seat, the vehicle can control the adjustable items to the corresponding angle or position based on the second user's adjustment operation. In other words, the vehicle will not restrict the adjustment operation of the second user in the second seat, thereby improving the second user's riding comfort and ensuring the second user's riding experience.

[0030] In a second aspect, a vehicle is provided, comprising at least a first seat and a second seat facing the same direction, and a control unit connected to each of the first and second seats. 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. The control unit is configured to: obtain first seat information of the first seat; when the first seat information indicates that a first user is occupying the first seat, obtain an adjustment restriction corresponding to the adjustable item of the second seat; the adjustment restriction is configured to limit the adjustment range of the adjustable item; and when a second user adjusts the adjustable item of the second seat, restrict the second user's adjustment operation based on the adjustment restriction corresponding to the adjustable item.

[0031] In one implementation of the second aspect, the first seat includes a pressure sensor connected to a control unit; the first seat information includes a pressure value corresponding to the first seat. The pressure sensor is configured to obtain the pressure value corresponding to the first seat and transmit the pressure value corresponding to the first seat to the control unit. The control unit is further configured to determine that the first seat information indicates the presence of a first user in the first seat when the pressure value corresponding to the first seat is greater than or equal to the first pressure value; and to determine that the first seat information indicates the absence of a user in the first seat when the pressure value corresponding to the first seat is less than the first pressure value.

[0032] In one implementation of the second aspect, the adjustable item includes a backrest angle of a second seat, and the adjustment restriction condition includes limiting the angular range of adjustment of the second seat's backrest angle. The control unit is further configured to: when a pressure value corresponding to the first seat is greater than or equal to a first pressure value and less than a second pressure value, obtain a first angular range corresponding to the second seat's backrest angle; and when the pressure value corresponding to the first seat is greater than or equal to the second pressure value and less than a third pressure value, obtain a second angular range corresponding to the second seat's backrest angle; the first angular range being greater than the second angular range.

[0033] In one 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 within which the second seat's position can be adjusted. The control unit is further configured to: 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, obtain a first distance range corresponding to the position of the second seat; and 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, obtain a second distance range corresponding to the position of the second seat; the first distance range being greater than the second distance range.

[0034] In one 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 configured to capture the first image corresponding to the first seat and transmit the first image to a control unit. The control unit is further configured to determine, based on the first image, whether a first user is present in the first seat.

[0035] In one implementation of the second aspect, the adjustable item includes a backrest angle of a second seat, and the adjustment restriction condition includes limiting the angular range of adjustment of the backrest angle of the second seat. The control unit is further configured to: obtain user information of a first user in the first image, 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 a first preset value and less than a second preset value, obtain a third angular 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, obtain a fourth angular range corresponding to the backrest angle of the second seat; the third angular range is greater than the fourth angular range.

[0036] In one implementation of the second aspect, the adjustable item includes the position of the second seat, and the adjustment restriction includes a distance range limiting the adjustment of the second seat's position. The control unit is further configured to: obtain user information of the first user in the first image, 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 a first preset value and less than a fourth preset value, obtain 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, obtain a fourth distance range corresponding to the position of the second seat; the third distance range is greater than the fourth distance range.

[0037] In one implementation of the second aspect, the control unit is also used to control the backrest angle of the second seat to be adjusted to the 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.

[0038] In one implementation of the second aspect, the control unit is further 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.

[0039] In one implementation of the second aspect, the first seat includes a seatbelt detection unit connected to the control unit; the first seat information includes seatbelt wearing information corresponding to the first seat. The seatbelt detection unit is configured to obtain the seatbelt wearing information corresponding to the first seat and transmit the seatbelt wearing information to the control unit. The control unit is further configured to: determine that the first seat information indicates the presence of a first user in the first seat when the seatbelt wearing information corresponding to the first seat indicates that the seatbelt of the first seat is being worn; and determine that the first seat information indicates that no user is seated in the first seat when the seatbelt wearing information corresponding to the first seat indicates that the seatbelt of the first seat is not being worn.

[0040] In an implementation method of the second aspect, the control unit is also used to, 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, control the adjustable item to be adjusted to a corresponding angle or position according to the adjustment operation of the second user.

[0057] In addition, the business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. Ordinary technicians in this field can know 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.

[0058] Seats are a feature that users interact with for extended periods of time while riding in public transportation, and their comfort significantly impacts the user experience. Currently, to ensure a better user experience on vehicles, high-speed trains, airplanes, and other modes of transportation, seat comfort can often be adjusted. There are many ways to adjust seat comfort, including providing comfortably shaped seats and seats with flexible adjustable features (e.g., adjustable backrests, ventilation and heating, massage functions, etc.).

[0059] However, for seats that offer flexible adjustments, each seat's functional adjustment is completely independent. For example, adjusting the seat pitch or seat back angle only adjusts the current seat. This improves the riding experience and comfort of the passenger in the current seat, but reduces the riding space for rear passengers or causes inconvenience to them. Therefore, while the current seat adjustment method can improve the riding experience of front-seat passengers, it affects the riding experience of rear-seat passengers.

[0060] Based on the above, an embodiment of the present application provides a seat adjustment method for adjusting the second seat of a first seat and a second seat that have the same orientation, wherein the second seat is located in the row in front of the first seat and corresponds to at least one adjustable item. In this method, first seat information for the first seat is obtained. When the first seat information indicates that a first user is present in the first seat, adjustment restrictions corresponding to the adjustable items of the second seat are obtained, wherein the adjustment restrictions are used to limit the adjustment range of the adjustable items. Furthermore, when a second user adjusts the adjustable items of the second seat, the second user's adjustment operation is restricted based on the adjustment restrictions corresponding to the adjustable items.

[0061] The above method can limit 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 front seat adjustment 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.

[0062] 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.

[0063] As shown in Figure 1, the vehicle may include seats 1, 2, ..., and N, and a control unit 101 connected to each seat. Seats 1-N are arranged vertically and face the same direction. Control unit 101 can obtain seat information for each seat and, based on the seat information for the rear seats, determine whether a first user is seated in the rear seats. If a user is seated in the rear seats, control unit 101 can determine adjustment restrictions for adjustable items in the front seats. If a second user adjusts an adjustable item in the front seats, control unit 101 can restrict the second user's adjustment based on the adjustment restrictions corresponding to the adjustable item.

[0064] 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 based on the pressure value corresponding to the seat, for example, when the pressure value is greater than or equal to a 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; alternatively, the control unit 101 may determine whether there is a user on the seat based on the image corresponding to the seat, for example, by identifying the content in the image, and determining that there is a user when the image includes the user, and determining that there is no user when the image does not include the user; alternatively, the control unit 101 may determine whether there is a user on the seat based on the seat belt wearing information, for example, when the seat belt wearing information indicates that the seat belt is being worn, it is determined that there is a user, and when the seat belt wearing information indicates that the seat belt is not being worn, it is determined that there is no user.

[0065] In other possible application scenarios, the control unit 101 may also determine whether a user is in the seat by combining any two or all of the seat's corresponding pressure value, image, and seatbelt wearing information. For example, when the seatbelt wearing information indicates that the seatbelt is not being worn, the control unit 101 may further determine whether a user is in the seat based on the seat's corresponding pressure value or image. Alternatively, when the seat's corresponding image includes a user, the control unit 101 may further determine whether a user is in the seat based on the seat's corresponding pressure value (here, a user who can affect the adjustment range of the second seat).

[0066] The aforementioned seat adjustable items may include seat position, seat back angle, etc., and the adjustment restrictions of the adjustable items are used to limit the adjustment range of the adjustable items. When a user is in the rear seat, the control unit 101 may obtain the adjustment restrictions corresponding to the seat position, such as obtaining the limited distance range between the front and rear seats; or the control unit 101 may also obtain the adjustment restrictions corresponding to the seat back angle, such as obtaining the limited angle range of the front seat back; or, the control unit 101 may simultaneously obtain the adjustment restrictions corresponding to the seat position and the seat back angle.

[0067] For example, in FIG1 , seat 1 is the front seat and seat 2 is the rear seat. The control unit 101 determines whether a first user is present in seat 2 based on the seat information of seat 2. If so, the control unit 101 obtains an adjustment restriction condition that limits the adjustment of seat 1. When a second user adjusts the backrest angle of seat 1, the control unit 101 can restrict the backrest angle of seat 1 adjusted by the second user to a certain angle range based on the adjustment restriction condition of the backrest angle of seat 1. When a second user adjusts the position of seat 1, the control unit 101 can restrict the second user from adjusting the position of seat 1 based on the adjustment restriction condition of the position of seat 1, thereby limiting the position adjustment range of seat 1 to a certain distance range. In this way, while ensuring the comfort of the second user corresponding to seat 1, a certain amount of space is left for the first user in seat 2, ensuring the first user's riding experience in seat 2.

[0068] In some possible application scenarios, the above-mentioned vehicle may further include one or more of a pressure sensor, a camera, a seat belt detection unit, an infrared sensor, etc. Specifically, a pressure sensor may be provided on each seat to detect the pressure value applied to the seat and transmit the corresponding pressure value to the control unit 101. The control unit 101 then determines whether there is a user in the rear seat based on the corresponding pressure value.

[0069] Multiple cameras may be installed in the vehicle's cabin, each camera capable of capturing seat images of multiple different seats and transmitting the seat images to the control unit 101. The control unit 101 can then determine whether a user is occupying the rear seat based on the seat images. Alternatively, a camera may be installed for each seat in the vehicle's cabin, each camera capable of capturing a seat image of a corresponding seat and transmitting the seat image to the control unit 101. The control unit 101 can then determine whether a user is occupying the rear seat based on the seat images.

[0070] A seat belt detection unit can also be set on each seat. Each seat belt detection unit can 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. The control unit 101 then determines whether there is a user on the rear seat based on the seat belt wearing information.

[0071] 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.

[0072] 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 seat, the occupied space volume, etc.

[0073] For example, when a user is in a rear seat, the system further determines whether the pressure value corresponding to the rear seat, while being greater than or equal to a first pressure value, is less than a second 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 may be restricted by a first gradient, i.e., obtaining a first angle range corresponding to the backrest angle of the front seat, or obtaining a first distance range corresponding to the position of the front seat. If the pressure value corresponding to the rear seat is greater than or equal to the second pressure value, the system further determines 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 may be restricted by a second gradient, i.e., obtaining a second angle range corresponding to the backrest angle of the front seat, or obtaining a second distance range corresponding to the position of the front seat. The fact that the first angle range is greater than the second angle range, and the first distance range is greater than the second distance range, indicates that the degree of restriction of the first gradient is less than that of the second gradient.

[0074] Furthermore, when the pressure value of the rear seat is greater than or equal to a third pressure value, the adjustable items of the front seat can be restricted by a third gradient, for example, prohibiting adjustment of the backrest angle or position of the front seat. This ensures the comfort of rear seat users even when they are heavier.

[0075] As another example, when a user is in a rear seat, the volume of space occupied by the user is further determined based on the image corresponding to the rear seat. If the volume of space occupied by the user is greater than or equal to a first preset value and less than a second preset value, the front seat's adjustable options may be restricted by a first gradient, i.e., a third angular range corresponding to the front seat's backrest angle is obtained, or a third distance range corresponding to the front seat's position is obtained. If the volume of space occupied by the user is greater than or equal to the second preset value and less than the third preset value, the front seat's adjustable options may be restricted by a second gradient, i.e., a fourth angular range corresponding to the front seat's backrest angle is obtained, or a fourth distance range corresponding to the front seat's position is obtained. If the third angular range is greater than the fourth angular range, and the third distance range is greater than the fourth distance range, then the first gradient's degree of restriction is less than the second gradient's degree of restriction.

[0076] Furthermore, when the volume of space occupied by rear seat users is greater than or equal to a third preset value, a third gradient of restrictions may be applied to the front seat adjustability, for example, prohibiting adjustment of the front seat backrest angle or position. This ensures rear seat user comfort even when the rear seat users occupy a large space.

[0077] The control unit 101 restricts user adjustment operations on the front seat. This may include, if the user in the front seat adjusts the front seat backrest angle, and the backrest angle exceeds an angle range corresponding to the front seat backrest angle (such as the first angle range, the second angle range, the third angle range, the fourth angle range, etc.), then controlling the front seat backrest angle to adjust to an angle corresponding to the maximum value of the angle range. If the user in the front seat adjusts the front seat position, and the front seat position exceeds a distance range corresponding to the front seat position (such as the first distance range, the second distance range, the third distance range, the fourth distance range, etc.), then controlling the front seat position to adjust to a position corresponding to the maximum value of the distance range. Thus, the control unit 101 can restrict front seat adjustment based on angle ranges or distance ranges, preventing the front seat backrest angle and / or front seat position from exceeding the restrictions.

[0078] It is understood that the "rear seat" mentioned above can be any seat other than the seat 1 shown in Figure 1. Moreover, the front seat and the rear seat are relative. For example, seat 2 is a rear seat relative to seat 1, and is a front seat relative to seat 3.

[0079] In other possible application scenarios, as shown in FIG2 , the vehicle may include a seat information detection unit 201 , a control unit 101 , a seat adjustment unit 202 , etc. Furthermore, the seat information detection unit 201 and the seat adjustment unit 202 are connected to the control unit 101 , respectively.

[0080] 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.

[0081] 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.

[0082] Each seat is equipped with a seat adjustment unit 202. In response to received control commands, the seat adjustment unit 202 can restrict the user's adjustment operations based on adjustment restriction conditions when the user adjusts an adjustable item of the front seat. For example, the seat adjustment unit 202 can restrict the user from adjusting the front seat backrest angle or the front seat position.

[0083] For example, the control unit 101 may be a low-cost microcontroller unit (MCU) and connected to the seat information detection unit 201 and the seat adjustment unit 202 via an interface such as CAN / RS485, thereby obtaining seat information from the seat detection unit 201 and sending adjustment restriction conditions to the seat adjustment unit 202. Alternatively, the control unit 101 may be another type of control device, which is not specifically limited in the embodiments of the present application.

[0084] In addition, when there is no user sitting in the rear seat, the control unit 101 will not restrict the adjustment operations of the user in the front seat. When the user in the front seat adjusts the adjustable items of the front seat, the control unit 101 can control the adjustable items to be adjusted to the corresponding angle or position according to the adjustment operations of the user in the front seat.

[0085] In some possible application scenarios, the connection between the control unit and the above-mentioned seat information detection unit and seat adjustment unit can adopt a centralized architecture or a distributed architecture.

[0086] For example, as shown in Figure 3, the control unit connects to the seat information detection unit and seat adjustment unit using a centralized architecture. Consequently, a single control unit is sufficient for each vehicle. For example, if each seat on the vehicle (e.g., seat 1, seat 2, seat 3, seat 4, ..., seat N, seat N+1) includes a seat information detection unit and a seat adjustment unit, the control unit is connected to each seat's seat information detection unit and seat adjustment unit.

[0087] The control unit receives the seat information sent by each seat information detection unit and, based on the seat information, determines whether a user is occupying the corresponding seat. If a user is occupying a seat, the control unit determines the adjustment restrictions corresponding to the adjustable items of the front row of seats in that seat and sends these restrictions as control commands to the seat adjustment unit of the front row of seats. For example, if a user is occupying seat 2 in Figure 3, the control unit may send a control command corresponding to the adjustment restrictions to the seat adjustment unit of seat 1 in front of seat 2.

[0088] As another example, referring to FIG4 , the connection between the control unit and the above-mentioned seat information detection unit and 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. Taking the example that each seat on a vehicle includes a seat information detection unit and a seat adjustment unit, each control unit can be connected to the seat information detection units and seat adjustment units of a part of the seats. For example, the control unit 1 in FIG4 can be connected to the seat information detection units and seat adjustment units of seats 1, 2, and 3, while the control unit 2 can be connected to the seat information detection units and seat adjustment units of seats 4, 5, and 6.

[0089] Control unit 1 receives seat information for seat 1 from the seat information detection unit of seat 1, seat information for seat 2 from the seat information detection unit of seat 2, and seat information for seat 3 from the seat information detection unit of seat 3. Control unit 1 determines, based on the seat information, whether a user is occupying the corresponding seat. If so, control unit 1 transmits a control instruction corresponding to an adjustment restriction condition to the seat adjustment unit of the seat in front of the seat. For example, if control unit 1 determines, based on the seat information of seat 2, that a user is occupying the seat, control unit 1 transmits a control instruction corresponding to an adjustment restriction condition to the seat adjustment unit of seat 1 in front of seat 2.

[0090] Control unit 2 receives seat information of seat 4, seat information of seat 5, and seat information of seat 6 from the seat information detection unit of seat 4. Control unit 2 determines whether a user is occupying the corresponding seat based on the seat information. If so, control unit 2 sends a control instruction corresponding to an adjustment restriction condition to the seat adjustment unit of the seat in front of the seat. For example, if control unit 2 determines based on the seat information of seat 5 that a user is occupying the seat, control unit 2 sends a control instruction corresponding to an adjustment restriction condition to the seat adjustment unit of seat 4 in front of seat 5.

[0091] In addition, 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.

[0092] 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.

[0093] The above-mentioned seat adjustment method is applied to a vehicle. When a user rides the vehicle, he or she can adjust the backrest angle or position of the seat he or she is currently riding in according to his or her own needs. If there are other users riding in the back seat at this time, the user in the front seat will be restricted in adjusting his or her seat. This will minimize the impact of the front seat adjustment on the users in the back seat while meeting the needs and comfort of the users in the front seat as much as possible.

[0094] As shown in FIG5 , the seat adjustment method may include the following steps S501 - S503 .

[0095] S501: A vehicle obtains first seat information of a first seat.

[0096] The vehicle includes at least a first seat and a second seat, wherein 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.

[0097] 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.

[0098] Exemplarily, the vehicle can obtain the pressure value corresponding to the first seat through the pressure sensor corresponding to the first seat, obtain the first image corresponding to the first seat through the camera corresponding to the first seat, and obtain the seat belt wearing information corresponding to the first seat through the seat belt detection unit corresponding to the first seat.

[0099] In some embodiments, the first seat information may indicate whether there is a first user in the first seat.

[0100] 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 in the first seat. When the pressure value corresponding to the first seat is less than the first pressure value, the first seat information can indicate that no user is in the first seat, or the impact of the adjustment of the second seat on the presence of the first user can be ignored (such as if a child is in the first seat). The first pressure value represents a preset pressure value, such as 35kg or 40kg (i.e., based on 40kg in the seat belt testing standard GB / T 24551). That is, when the pressure value corresponding to the first seat is greater than or equal to the first pressure value, the impact of the adjustment of the second seat on the first user can be considered.

[0101] The content included in the first image may reflect whether the first seat is occupied and the volume of space occupied by the seated first user.

[0102] 6 , when the first image includes the image of the first user, the first image may indicate that the first user is sitting in the first seat. The first image may also include the image of the first seat, making it easier to determine whether the first user is sitting in the first seat.

[0103] The seatbelt wearing information corresponding to the first seat can reflect whether the first seat is occupied. When the seatbelt wearing information corresponding to the first seat indicates that the seatbelt of the first seat is being worn, the first seat information can indicate that the first user is in the first seat; when the seatbelt wearing information corresponding to the first seat indicates that the seatbelt of the first seat is not being worn, the first seat information can indicate that no user is in the first seat.

[0104] In some possible application scenarios, the vehicle may determine whether the first user is in the first seat based on any of the above first seat information. In other possible application scenarios, the vehicle may also determine whether the first user is in the first seat based on any two or all of the above first seat information.

[0105] For example, the vehicle may first determine whether the pressure value corresponding to the first seat is greater than or equal to the first pressure value. If the pressure value corresponding to the first seat is greater than or equal to the first pressure value, the vehicle may further determine whether the seatbelt wearing information corresponding to the first seat indicates that the seatbelt of the first seat is being worn. If the seatbelt wearing information indicates that the seatbelt of the first seat is being worn, the vehicle may determine that the first user is in the first seat. Furthermore, the first seat information also indicates that the first user is in the first seat. In this way, the presence of the first user can be determined based on both the pressure value and the seatbelt wearing, thereby improving the accuracy of determining the first user.

[0106] S502: When the first seat information indicates that the first user is present on the first seat, the vehicle obtains an adjustment restriction condition corresponding to an adjustable item of the second seat.

[0107] 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, 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.

[0108] In some embodiments, when the adjustment constraint includes limiting the angle range of the second seat's backrest angle, the adjustment constraint may also include the first user's weight, occupied space volume, etc., with different weights and / or occupied space volumes corresponding to different restricted angle ranges. Furthermore, the vehicle can employ different restricted angle ranges in the adjustment constraint under different circumstances.

[0109] For example, 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 a 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 a second angle range corresponding to the backrest angle of the second seat.

[0110] 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 indicates that the first user in the first seat is relatively light, likely a thin person. Therefore, the restrictions on the second seat backrest angle can be relaxed, resulting in a larger first angle range. See FIG7(a), where the position of the seat backrest indicated by the solid line represents the initial position of the backrest angle, and the position of the seat backrest indicated by the dashed 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 indicates that the first user in the first seat is relatively heavy, likely a slightly overweight or slightly overweight person. Therefore, the restrictions on the second seat backrest angle need to be stricter, resulting in a smaller second angle range than the first angle range. See FIG7(b). The first, second, and third pressure values ​​all represent preset pressure values. The second pressure value can be 60 kg, 65 kg, 70 kg, etc., and the third pressure value can be 80 kg, 85 kg, etc.

[0111] It can be seen that when the pressure value corresponding to the first seat is in different ranges, the vehicle's restrictions on the second seat backrest 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.

[0112] 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.

[0113] 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 the space occupied by the first user based on the user information. When the volume of the 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 the 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.

[0114] When the volume of the space occupied by the first user is greater than or equal to the first preset value and less than the second preset value, it indicates that the first user is relatively small and may be a thin person. In this case, the restriction on the second seat back angle can be relaxed, and the third angle range is larger. When the volume of the space occupied by the first user is greater than or equal to the second preset value and less than the third preset value, it indicates that the first user is relatively large and may be a slightly overweight or slightly plump person. In this case, the restriction on the second seat back angle needs to be stricter, and the fourth angle range is smaller than the third angle range.

[0115] 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, which is not specifically limited in the embodiments of the present application.

[0116] 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, weight and other physical conditions of the rear users, and reduce the impact of the front users on the rear users when adjusting their seats.

[0117] 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.

[0118] In other embodiments, when the adjustment constraint includes limiting the distance range for adjusting the position of the second seat, the adjustment constraint may also be configured with corresponding distance limits based on the weight of the first user, the volume of space occupied, etc., with different weights and / or volumes of space corresponding to different distance limits. Furthermore, the vehicle may obtain different distance limits in the adjustment constraint under different circumstances.

[0119] For example, 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 a 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 a second distance range corresponding to the position of the second seat.

[0120] 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 indicates that the first user on the first seat is relatively light, possibly a thin person. In this case, the restrictions on the second seat position can be relaxed, and the first distance range is larger, as shown in FIG8 (a), where the seat position indicated by the solid line represents the initial position of the seat, and the seat position 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 indicates that the first user on the first seat is relatively heavy, possibly a slightly overweight or slightly plump person. In this case, the restrictions on the second seat position need to be stricter, and the second distance range is smaller than the first distance range, as shown in FIG8 (b).

[0121] 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.

[0122] 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.

[0123] 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.

[0124] As another example, the vehicle may also obtain user information of the first user in the first image and, based on the user information, determine the volume of the space occupied by the first user. When the volume of the space occupied by the first user is greater than or equal to a first preset value and less than a fourth preset value, a third distance range corresponding to the position of the second seat is obtained. When the volume of the space occupied by the first user is greater than or equal to a fourth preset value and less than a fifth preset value, a fourth distance range corresponding to the position of the second seat is obtained.

[0125] When the volume of the space occupied by the first user is greater than or equal to the first preset value and less than the fourth preset value, it indicates that the first user is relatively small and may be a thin person. In this case, the restriction on the second seat position can be relaxed, and the third distance range is larger. When the volume of the space occupied by the first user is greater than or equal to the fourth preset value and less than the fifth preset value, it indicates that the first user is relatively large and may be a slightly overweight or slightly plump person. In this case, the restriction on the second seat position needs to be stricter, and the fourth distance range is smaller than the third distance range.

[0126] In some possible application scenarios, the fourth preset value may be the same as the second preset value described above, and the fifth preset value may be the same as the third preset value described above. Furthermore, the third distance range may be the same as the first distance range described above, and the fourth distance range may be the same as the second distance range described above. This is not specifically limited in the embodiments of the present application.

[0127] 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, weight and other physical conditions of the rear users, and reduce the impact of the front users on the rear users when adjusting their seats.

[0128] 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.

[0129] In addition, it can be understood that the above-mentioned 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 embodiment of the present application are all preset, and the specific values ​​are determined according to the actual situation of the vehicle and / or the users on board. The specific values ​​of the above-mentioned preset values ​​are not specifically limited in the embodiment of the present application.

[0130] 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.

[0131] The restriction on the adjustment operation of the second user by the vehicle means restricting the backrest angle of the second seat to not exceed the corresponding angle range, and / or restricting the position of the second seat to not exceed the distance range corresponding to the second seat.

[0132] For example, if the second user adjusts the backrest angle of the second seat so that the backrest angle of the second seat exceeds the angle range corresponding to the second seat backrest angle, 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, if the angle range corresponding to the backrest angle of the second seat is 90-100 degrees, if the backrest angle of the second seat is adjusted by the second user from 90 degrees to 105 degrees, or from 95 degrees to 105 degrees, both of which will cause the backrest angle to exceed the angle range limit, the vehicle will control the backrest angle of the second seat to finally be 100 degrees.

[0133] As another example, if the second user adjusts the second seat's position so that the second seat's position exceeds the distance range corresponding to the second seat's position, the vehicle controls the second seat's position to adjust to the position corresponding to the maximum value of the distance range. For example, if the second seat's position corresponds to a distance range of 0-0.2m (the range of adjustment backward from the initial position), and if the second user adjusts the second seat's position from 0m (i.e., the initial position) to 0.3m, or from 0.1m to 0.3m, both of which cause the seat's position to exceed the corresponding distance range limit, the vehicle will control the second seat's position to ultimately be at 0.2m.

[0134] As can be seen from the above, the seat adjustment method provided in the embodiment of the present application can restrict the adjustment of the front seat based on the situation of the first user sitting in the rear seat, thereby reducing the impact of the front seat adjustment 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.

[0135] In some embodiments, when the first seat information indicates that no user is seated in the first seat, adjustments to the adjustable items of the second seat may not affect other users. In this case, if the second user adjusts the adjustable items of the second seat, the vehicle can control the adjustable items to the corresponding angle or position based on the second user's adjustment operation. In other words, the vehicle will not restrict the adjustment operation of the second user in the second seat, thereby improving the second user's riding comfort and ensuring the second user's riding experience.

[0136] It is understood 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 seat backrest can be adjusted from the initial position, or the seat backrest can be adjusted from the current position. For example, the initial position of the seat backrest can be a position where the backrest can be 90 degrees to the seat cushion, and the seat backrest angle 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.

[0137] Exemplarily, the angle range for limiting the adjustment of the backrest angle in the embodiment of the present application refers to the angle range for adjusting from the initial position of the seat back shown in Figure 7 (a) to a direction greater than 90°, and the distance range for limiting the adjustment of the seat position refers to the distance range for adjusting from the initial position of the seat position shown in Figure 8 (a) toward the rear seat direction.

[0138] In some embodiments, the vehicle may first determine a restriction strategy for the second seat's adjustable items based on the pressure value corresponding to the first seat and the seatbelt wearing information. The vehicle may then determine the weight and volume of the first user based on the pressure value of the first seat and / or the first image, thereby obtaining adjustment restrictions under the corresponding restriction strategy, such as a restricted angle range and / or a restricted distance range.

[0139] For example, as shown in FIG9 , a vehicle determines the presence of a first user in the first seat based on the pressure value corresponding to the first seat. The vehicle then determines whether the first seat belt is being used based on the seat belt wearing information. If the seat belt is not being used, the vehicle determines a restriction policy that restricts the adjustment of the second seat's adjustable items to a certain extent. If the seat belt is being used, the vehicle determines a restriction policy that disallows adjustment of the second seat's adjustable items, or significantly restricts adjustment of the second seat's adjustable items.

[0140] Afterwards, the vehicle further determines the restricted angle range 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 embodiment, and determines the restricted distance range under different restriction strategies, such as the first distance range, the second distance range, etc. in the above embodiment.

[0141] In some embodiments, the aforementioned seatbelt wearing information can not only be used to determine whether a user is seated, but can also be used to encourage users to actively use their seatbelts. This is because, in some possible scenarios, if a user is actually seated in the rear seat but not wearing a seatbelt, the vehicle may determine that no one is in the rear seat and, therefore, not restrict front seat adjustment. To avoid this, the rear seat user may actively use their seatbelt, prompting the vehicle to detect the presence of a user and restrict front seat adjustment. This not only allows rear seat users to ride more comfortably, but also improves travel safety.

[0142] 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.

[0143] When the vehicle obtains the adjustment restriction condition for the second seat, it can send the adjustment restriction condition to the seat adjustment unit of the second seat. The seat adjustment unit can determine whether to restrict the adjustment operation of the adjustable items of the second seat or whether to restrict the adjustment operation of the second user based on the seating situation of the second user in the second seat.

[0144] For example, as shown in FIG10 , after the seat adjustment unit receives the adjustment restriction condition, if no user is seated in the second seat, the adjustment restriction condition takes effect immediately. Subsequently, if a user adjusts an adjustable item of the second seat, the seat adjustment unit imposes restrictions based on the adjustment restriction condition.

[0145] After the seat adjustment unit receives the adjustment restriction, if a user is already seated in the second seat, the adjustment restriction will not take effect. The seat adjustment unit will not force the second seat's already adjusted adjustable items to meet the adjustment restriction, thus avoiding any negative impact on the user in the second seat. If the user in the second seat then stands up or readjusts the second seat, the adjustment restriction will take effect, and the seat adjustment unit will apply the restriction based on the adjustment restriction.

[0146] 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 a timely manner according to the riding conditions of the first user on the first seat, the weight of the first user, the volume of the first user, etc.

[0147] For example, the vehicle obtains first seat information in real time. If the first seat information initially obtained indicates that no user is occupying the first seat, the vehicle may not restrict the adjustment of the second seat. Subsequently, if the first seat is occupied by the first user, the vehicle will determine the presence of the first user based on the first seat information obtained at this time, and will then begin restricting the adjustment of the second seat according to the method of the aforementioned embodiment. If the first user in the first seat changes, due to the potential difference in weight and size, the vehicle may also adjust the restricted angle range and / or distance range for the second seat based on the pressure value, first image, and other factors in the first seat information.

[0148] It is understood that the collection, storage, use, processing, transmission, provision, and disclosure of user information in the embodiments of this application all comply with relevant laws and regulations and do not violate public order and good morals. For example, in the embodiments of this application, obtaining user information from the first image and determining the volume of space occupied by the user based on the user information are all performed with the user's authorization.

[0149] In some schemes, multiple embodiments of the present application can be combined, and the combined scheme can be implemented. Optionally, some operations in the process of each method embodiment are optionally combined, and / or the order of some operations is optionally changed. In addition, the execution order between the steps of each process is only exemplary and does not constitute a restriction on the execution order between the steps. There can also be other execution orders between the steps. It is not intended to indicate that the execution order is the only order in which these operations can be performed. Those of ordinary skill in the art will think of many ways to reorder the operations described in the embodiments of the present application. In addition, it should be noted that the process details involved in a certain embodiment of the present application are also applicable to other embodiments in a similar manner, or different embodiments can be used in combination.

[0150] Furthermore, some steps in the method embodiments may be equivalently replaced with other possible steps. Alternatively, some steps in the method embodiments may be optional and may be deleted in certain usage scenarios. Alternatively, other possible steps may be added to the method embodiments.

[0151] Furthermore, the various method embodiments may be implemented separately or in combination.

[0152] It is understandable that in order to achieve the above functions, the aforementioned means of transport includes hardware and / or software modules corresponding to the execution of each function. In combination with the algorithm steps of each example described in the embodiments disclosed herein, the present application can be implemented in the form of hardware or a combination of hardware and computer software.
