Technical Field

[0001] This invention relates to the field of vehicle technology, and more specifically, to a seat adaptive adjustment method, device, electronic device, and vehicle. Background Technology

[0002] In traditional vehicles, the seats can be unfolded into a zero-gravity posture for passengers to lie down with one click. This zero-gravity posture is a fixed default posture that does not distinguish between the height and weight of passengers. If the zero-gravity posture is to be adapted to the passenger's body shape, the passenger needs to manually adjust the seat variables such as the leg rest angle, leg rest extension length, seat cushion flip angle, and backrest rotation angle according to their own feelings, which is quite cumbersome. Summary of the Invention

[0004] To address the aforementioned problems, the present invention provides a seat adaptive adjustment method, device, electronic device, and vehicle.

[0005] In a first aspect, the present invention provides a seat adaptive adjustment method, comprising: Obtain the user's height parameters; The seat is adjusted to an initial zero-gravity posture corresponding to the height parameters. Obtain the seat surface parameters when the user is lying on the seat in the initial zero-gravity posture; The seat is adjusted to a target zero-gravity posture that meets the user's comfort requirements based on the seat surface parameters.

[0006] Optionally, the seat surface parameters include the seat surface indentation and seat surface pressure at various parts of the seat; The step of controlling the seat to adjust to a target zero-gravity posture that meets the user's needs based on the seat surface parameters includes: When the indentation of the seat surface at at least one location exceeds the preset indentation range, and / or the pressure distribution of the seat surface is uneven, adjust the variable parameters of the seat until the seat reaches the target zero-gravity posture; When the indentation of the seat surface at all locations meets the preset indentation range and the seat surface pressure distribution is balanced, the initial zero-gravity posture is taken as the target zero-gravity posture, and the seat is controlled to maintain the current initial zero-gravity posture.

[0007] Optionally, adjusting the variable parameters of the seat until the seat reaches the target zero-gravity posture includes: If an air bag is provided at a location where the seat surface indentation exceeds a preset indentation range, the inflation amount of the air bag and the variable parameter are adjusted until the seat surface indentation meets the preset indentation range and the seat surface pressure distribution is balanced. If an airbag is not installed in a part of the seat surface where the indentation exceeds the preset indentation range, the variable parameter is adjusted until the indentation of the seat surface meets the preset indentation range and the pressure distribution of the seat surface is even.

[0008] Optionally, controlling the seat to adjust to an initial zero-gravity posture corresponding to the height parameter based on the height parameter includes: When the height parameter is greater than or equal to the first preset height, the seat is controlled to adjust to the first initial zero-gravity posture; When the height parameter is greater than or equal to the second preset height and less than the first preset height, the seat is controlled to adjust to the second initial zero-gravity posture. When the height parameter is greater than or equal to the third preset height and less than the second preset height, the seat is controlled to adjust to the third initial zero-gravity posture; When the height parameter is less than the third preset height, the seat is controlled to adjust to the fourth initial zero-gravity posture.

[0009] Optionally, the seat surface indentation of each part includes backrest indentation, seat cushion indentation, and leg rest indentation; the preset indentation range includes preset backrest indentation range, preset seat cushion indentation range, and preset leg rest indentation range; the variable parameters include seat cushion flip angle, backrest flip angle, leg rest lifting angle, and leg rest extension length; and the seat surface pressure distribution includes backrest pressure distribution, seat cushion pressure distribution, and leg rest pressure distribution. Adjusting the variable parameters of the seat until the seat reaches the target zero-gravity posture includes: When the backrest indentation exceeds the preset backrest indentation range or the backrest pressure distribution is uneven, adjust the backrest flip angle and / or the seat cushion flip angle to increase the angle between the backrest and the seat cushion until the backrest indentation is within the preset backrest indentation range and the backrest pressure distribution is even. When the cushion indentation exceeds the preset cushion indentation range or the cushion pressure distribution is uneven, adjust the backrest flip angle and / or the cushion flip angle to increase the angle between the backrest and the cushion until the cushion indentation is within the preset cushion indentation range and the cushion pressure distribution is even. When the leg support indentation exceeds the preset leg support indentation range or the leg support pressure distribution is uneven, reduce the leg support lifting angle and / or increase the leg support extension length until the leg support indentation is within the preset leg support indentation range and the leg support pressure distribution is even.

[0010] Optionally, the seat includes a backrest, a seat cushion, and a leg rest. Pressure sensors and strain gauges are arranged on the backrest, the seat cushion, and the leg rest.

[0015] The beneficial effects of the seat adaptive adjustment method of the present invention are as follows: By acquiring the user's height parameters and controlling the seat adjustment to an initial zero-gravity posture corresponding to the height parameters, the initial zero-gravity posture of the seat can be better matched to users of different heights while coarsely adjusting the zero-gravity posture of the seat, so that the user has a certain degree of comfort throughout the entire process of subsequent adaptive adjustment while lying on the seat. Moreover, by acquiring the seat surface parameters when the user lies on the seat in the initial zero-gravity posture, and controlling the seat adjustment to a target zero-gravity posture that meets the user's comfort requirements based on the seat surface parameters, the zero-gravity posture of the seat can be finely adjusted according to the height of different users after coarse adjustment, so that the seat can automatically adjust to a zero-gravity posture that meets the comfort needs of users of different heights. The entire adjustment process is simple, convenient, and efficient. In addition, by first coarsely adjusting the seat to the initial zero-gravity posture and then finely adjusting it to the target zero-gravity posture, the difficulty of seat adjustment can be reduced and the range of seat fine adjustment can be reduced, thereby further improving the adjustment efficiency.

[0021] In related technologies, the seat supports one-click unfolding to a zero-gravity posture for passengers to lie down. However, this zero-gravity posture is a default fixed posture that does not distinguish between the height and weight of passengers. If the zero-gravity posture is to be adapted to the passenger's body shape, the passenger needs to manually adjust the seat's variables such as the leg rest angle, leg rest extension length, seat cushion flip angle, and backrest rotation angle according to their own feelings, which is quite cumbersome.

[0022] To address the problems existing in the aforementioned related technologies, embodiments of the present invention provide a seat adaptive adjustment method, device, electronic device, and vehicle.

[0023] Combination Figure 1 As shown, an embodiment of the present invention provides a seat adaptive adjustment method comprising the following steps: S100: Obtain the user's height parameters; Specifically, a user's height can be obtained through voice interaction with the vehicle's intelligent control system, or by manually inputting their height on the in-vehicle central control screen or a vehicle-compatible mobile app. Alternatively, a 3D scan of the user can be performed using an in-vehicle VR (Virtual Reality) device when they enter the vehicle. In other words, methods for obtaining a user's height include at least one of the following: voice interaction, screen input, mobile app input, and VR device scanning.

[0024] S200: Adjust the seat to the initial zero-gravity posture corresponding to the height parameters based on the height parameters; Specifically, the space between the dashboard and the second-row seats is the maximum boundary that allows users to lie down on the front seats, and it is also the environmental boundary that constrains the user's legs, feet, and torso. When the user lies down on the front seats, the gaps between the front seat back and the second-row seat cushion, the gaps between the user's calves and the dashboard, the gaps between the user's toes and the dashboard, and the gaps between the user's heels and the carpet need to meet the MTM (Meat to Metal) constraint. The MTM constraint is a standard used in ergonomic design to quantify the minimum gap between human body parts and hard surfaces. It is mainly used to evaluate seat comfort and ensure that key body parts maintain a reasonable distance from the seat frame, backrest, and other hard structures. When a user lies down in a chair, environmental constraints cause various angles to fall within a certain range, such as the backrest angle (the angle between the backrest and the vertical plane), thigh angle (the angle between the thigh axis and the horizontal plane), ankle angle (the angle between the foot and the lower leg), knee angle (the angle between the lower leg axis and the thigh axis), and trunk angle (the angle between the trunk axis and the thigh axis). These ranges typically differ for users of different heights, resulting in different zero-gravity chair postures. Therefore, user heights can be divided into multiple height ranges. An initial zero-gravity chair posture can be pre-set for each height range based on simulation analysis or actual human comfort tests, establishing a one-to-one correspondence between each height range and each initial zero-gravity posture of the chair.

[0025] S300: Obtain the seat surface parameters when the user is lying on the seat in the initial zero-gravity posture; Specifically, since users exert pressure on the seat surface when lying down, causing the seat surface to indent, the amount of seat surface indentation and seat surface pressure are usually used as seat surface parameters to more accurately determine whether there is stress concentration when the user lies down, so that the target zero-gravity posture after the seat adaptively adjusts is more in line with the user's comfort requirements.

[0026] S400 controls the seat adjustment to a target zero-gravity posture that meets the user's comfort requirements based on the seat surface parameters.

[0027] Specifically, when a user is comfortably lying on the seat, their body is not being pressed against by any foreign objects. At this time, the seat surface parameters are within a reasonable range. If the seat surface parameters exceed this reasonable range, it indicates that there is a foreign object in a certain part of the user's body, such as the lower back or shoulders being pressed against. At this time, the vehicle controller can control the seat to make adaptive adjustments, such as adjusting the backrest flip angle, seat cushion flip angle, leg rest lift angle, and leg rest extension length, until the seat surface parameters are within a reasonable range. The current zero-gravity posture of the seat is the target zero-gravity posture that meets the user's comfort requirements.

[0028] In this embodiment, by acquiring the user's height parameters and controlling the seat to adjust to an initial zero-gravity posture corresponding to those parameters, the initial zero-gravity posture of the seat can be more suitable for users of different heights while coarsely adjusting the zero-gravity posture. This ensures that the user is comfortable throughout the subsequent adaptive adjustment process while lying on the seat. Furthermore, by acquiring the seat surface parameters when the user is lying on the seat in the initial zero-gravity posture and controlling the seat to adjust to a target zero-gravity posture that meets the user's comfort requirements, the zero-gravity posture of the seat can be finely adjusted according to the different heights of users after the coarse adjustment. This allows the seat to automatically adjust to a zero-gravity posture that meets the comfort needs of users of different heights. The entire adjustment process is simple, convenient, and efficient. In addition, by first coarsely adjusting the seat to the initial zero-gravity posture and then finely adjusting it to the target zero-gravity posture, the difficulty of adjusting the seat can be reduced, the range of fine-tuning can be decreased, and the adjustment efficiency can be further improved.

[0029] Optionally, the seat surface parameters include the seat surface indentation and seat surface pressure at various parts of the seat; Step S400 specifically includes: When the indentation of the seat surface at at least one location exceeds the preset indentation range, and / or the seat surface pressure distribution is uneven, adjust the variable parameters of the seat until the seat reaches the target zero-gravity posture. When the indentation of the seat surface at all locations meets the preset indentation range and the seat surface pressure distribution is balanced, the initial zero-gravity posture is taken as the target zero-gravity posture, and the seat is controlled to maintain the current initial zero-gravity posture.

[0030] Specifically, a chair mainly includes a backrest and a seat cushion. Some chairs also include a leg rest. For ease of description, this example uses a chair with a backrest, seat cushion, and leg rest. Pressure sensors and strain gauges can be installed in the backrest, seat cushion, and leg rest. When a user lies on the chair, the strain gauges measure the indentation at different parts of the seat to obtain the seat surface indentation, and the pressure sensors measure the pressure on different parts of the seat to obtain the seat surface pressure. The seat surface indentation includes the backrest indentation, seat cushion indentation, and leg rest indentation. Correspondingly, preset indentation ranges include preset backrest indentation ranges, preset seat cushion indentation ranges, and preset leg rest indentation ranges. For example, the preset backrest indentation range can be designed to be between 30mm and 40mm, and the preset seat cushion indentation range can be designed to be between 25mm and 35mm. When the seat indentation exceeds the preset indentation range at at least one location—that is, the backrest indentation exceeds the preset backrest indentation range, and / or the seat cushion indentation exceeds the preset seat cushion indentation range, and / or the leg rest indentation exceeds the preset leg rest indentation range—it indicates that the pressure distribution in that area is high, resulting in stress concentration and a larger indentation. This also indirectly indicates that the MTM gap in that area is smaller, causing the corresponding part of the user's body to experience a foreign object sensation, i.e., a hard object pressing against it. At this time, the vehicle controller can adjust the seat to the target zero-gravity posture to eliminate the foreign object sensation. Seat surface pressure includes backrest pressure, seat cushion pressure, and leg rest pressure. A backrest pressure distribution map can be plotted based on the detected backrest pressure, a seat cushion pressure distribution map can be plotted based on the detected seat cushion pressure, and a leg rest pressure distribution map can be plotted based on the detected leg rest pressure. When a user lies comfortably on a seat, different parts of the seat will display corresponding comfort pressure value distribution maps, such as backrest comfort pressure value distribution maps, seat cushion comfort pressure value distribution maps, and leg rest comfort pressure value distribution maps. These comfort pressure value distribution maps for different parts of the seat can be drawn based on comfort pressure value ranges obtained from simulation analysis or actual large-scale model tests. When there is an uneven distribution of seat surface pressure at at least one location—that is, when the seat surface pressure in different parts of the seat exceeds the corresponding comfort pressure value distribution range (e.g., backrest pressure distribution exceeds the backrest comfort pressure value distribution range, and / or seat cushion pressure distribution exceeds the seat cushion comfort pressure value distribution range, and / or leg rest pressure distribution exceeds the leg rest comfort pressure value distribution range)—it indicates that the pressure distribution in that area is too high, resulting in stress concentration, and also suggests that a hard object is pressing against the corresponding part of the user's body.When either the seat indentation or seat pressure at various points on the seat does not meet comfort requirements—that is, when the seat indentation exceeds the preset range and / or the seat pressure distribution is uneven—the seat can be adjusted using parameters such as the backrest tilt angle, seat cushion tilt angle, leg rest lift angle, and leg rest extension length until the foreign body sensation disappears. This indicates that the seat indentation meets the preset range and the seat pressure distribution is balanced, and the seat's posture at this point is the target zero-gravity posture. Conversely, when the seat indentation at all points meets the preset range and the seat pressure distribution is balanced, the initial zero-gravity posture of the seat meets the user's comfort requirements. In this case, the initial zero-gravity posture can be used as the target zero-gravity posture, and the seat can be maintained in this initial zero-gravity posture.

[0031] In this way, by using the seat indentation and seat pressure of various parts of the seat as seat parameters, it is easier to accurately determine whether there is stress concentration when the user is lying on the seat. This makes the target zero-gravity posture after the seat adaptively adjusts more in line with the user's comfort requirements. Moreover, by using one of the seat indentation and seat pressure for secondary judgment, that is, both the seat indentation and seat pressure must meet the comfort conditions, the accuracy of adjustment can be improved.

[0032] Optionally, the variable parameters of the seat include the backrest flip angle, the seat cushion flip angle, the leg rest lift angle, and the leg rest extension length; the seat surface pressure distribution includes the backrest pressure distribution, the seat cushion pressure distribution, and the leg rest pressure distribution; wherein, the backrest flip angle refers to the angle between the backrest and the vertical plane parallel to the backrest flip axis, the seat cushion flip angle refers to the angle between the seat cushion and the horizontal plane, and the leg rest lift angle refers to the angle between the leg rest and the horizontal plane; In step S400, adjusting the variable parameters of the seat until the seat reaches the target zero-gravity posture specifically includes: When the backrest indentation exceeds the preset backrest indentation range or the backrest pressure distribution is uneven, adjust the backrest tilt angle and / or seat cushion tilt angle to increase the angle between the backrest and seat cushion until the backrest indentation is within the preset backrest indentation range and the backrest pressure distribution is even. Specifically, when the backrest indentation exceeds the preset backrest indentation range or the backrest pressure distribution is uneven, meaning that either the backrest indentation or the backrest pressure does not meet the comfort requirements, it indicates that there is stress concentration in local areas of the user's torso, such as the waist or shoulders. In this case, based on the initial zero-gravity posture of the seat, the angle between the backrest and the seat cushion can be increased by increasing the backrest tilt angle and / or decreasing the seat cushion tilt angle, thereby eliminating the stress concentration in this area and ensuring that the backrest indentation and backrest pressure meet the comfort requirements, that is, the backrest indentation is within the preset backrest indentation range and the backrest pressure distribution is balanced.

[0033] When the seat cushion indentation exceeds the preset seat cushion indentation range or the seat cushion pressure distribution is uneven, adjust the backrest flip angle and / or seat cushion flip angle to increase the angle between the backrest and the seat cushion until the seat cushion indentation is within the preset seat cushion indentation range and the seat cushion pressure distribution is even. Specifically, when the seat cushion indentation exceeds the preset seat cushion indentation range or the seat cushion pressure distribution is uneven, meaning that either the seat cushion indentation or the seat cushion pressure does not meet the comfort requirements, it indicates that there is stress concentration on the user's buttocks. In this case, based on the initial zero-gravity posture of the seat, the angle between the backrest and the seat cushion can be increased by increasing the backrest tilt angle and / or decreasing the seat cushion tilt angle, thereby eliminating the stress concentration in this area and ensuring that the seat cushion indentation and seat cushion pressure meet the comfort requirements, that is, the seat cushion indentation is within the preset seat cushion indentation range and the seat cushion pressure distribution is even.

[0034] When the leg support indentation exceeds the preset leg support indentation range or the leg support pressure distribution is uneven, reduce the leg support lifting angle and / or increase the leg support extension length until the leg support indentation is within the preset leg support indentation range and the leg support pressure distribution is even.

[0035] Specifically, when the leg support indentation exceeds the preset leg support indentation range or the leg support pressure distribution is uneven, that is, when either the leg support indentation or the leg support pressure does not meet the comfort conditions, it indicates that there is stress concentration in the user's legs. At this time, based on the initial zero-gravity posture of the seat, the stress concentration in this area can be eliminated by raising the lower leg support angle and / or increasing the leg support extension length, so that the leg support indentation and leg support pressure meet the comfort conditions, that is, the leg support indentation is within the preset leg support indentation range and the leg support pressure distribution is even.

[0036] This allows for targeted adjustments to the corresponding seat parameters based on the pressure applied to specific parts of the user's body, ensuring that the seat's target zero-gravity posture better meets the user's comfort requirements while achieving adaptive adjustment.

[0037] Optionally, in step S400, adjusting the variable parameters of the seat until the seat reaches the target zero-gravity posture includes: If airbags are installed in areas where the seat surface indentation exceeds the preset indentation range and / or in areas where the seat surface pressure distribution is uneven, adjust the inflation volume and variable parameters of the airbags until the seat surface indentation meets the preset indentation range and the seat surface pressure distribution is even. If airbags are not installed in areas where the seat surface indentation exceeds the preset indentation range and / or in areas where the seat surface pressure distribution is uneven, adjust the variable parameters until the seat surface indentation meets the preset indentation range and the seat surface pressure distribution is even.

[0038] In this optional embodiment, airbags are provided in localized areas (e.g., areas with high pressure distribution) of the seat back, seat cushion, and leg rest. When airbags are provided in areas where the seat indentation and / or seat pressure do not meet comfort requirements, the inflation level of the airbags can be adjusted by inflating or deflating them. If adjusting the inflation level eliminates the user's discomfort in that area, there is no need to adjust the seat's variable parameters. If adjusting the inflation level to the maximum does not eliminate the user's discomfort, the seat's variable parameters are then adjusted until the seat indentation and seat pressure meet comfort requirements, i.e., the seat indentation meets a preset range and the seat pressure distribution is balanced. When the seat does not have airbags in areas where the seat indentation and / or seat pressure do not meet comfort requirements, the seat's variable parameters are directly adjusted until the seat reaches the target zero-gravity posture. This achieves the adjustment of the zero-gravity posture of the seat equipped with airbags.

[0039] Optionally, step S200 specifically includes: When the height parameter is greater than or equal to the first preset height, control the seat to adjust to the first initial zero-gravity posture; When the height parameter is greater than or equal to the second preset height and less than the first preset height, control the seat to adjust to the second initial zero-gravity posture. When the height parameter is greater than or equal to the third preset height and less than the second preset height, control the seat to adjust to the third initial zero-gravity posture. When the height parameter is less than the third preset height, the control seat is adjusted to the fourth initial zero-gravity posture.

[0040] In this optional embodiment, the height of different users is divided into four ranges. For example, the first preset height is set to 1.88m, the second preset height is set to 1.75m, and the third preset height is set to 1.55m. The four height ranges are: a first height range greater than or equal to 1.88m, a second height range greater than 1.75m and less than 1.88m, a third height range greater than 1.55m and less than 1.75m, and a fourth height range less than or equal to 1.55m. After the user gets in the vehicle, if the user's height falls within the first height range, the seat is adjusted to a first initial zero-gravity posture; if the user's height falls within the second height range, the seat is adjusted to a second initial zero-gravity posture; if the user's height falls within the third height range, the seat is adjusted to a third initial zero-gravity posture; and if the user's height falls within the fourth height range, the seat is adjusted to a fourth initial zero-gravity posture. In this way, while coarsely adjusting the zero-gravity posture of the seat, it is ensured that the initial zero-gravity posture of the seat can better match users of different heights, so that users can have a certain degree of comfort throughout the entire process of lying on the seat and making subsequent adaptive adjustments.

The second acquisition module 230 is used to acquire the seat surface change parameters of the seat when the user is lying on the seat in the initial zero gravity posture; The second control module 240 is used to control the seat to adjust to a target zero-gravity posture that meets the user's needs based on the seat surface change parameters.
