[0023] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0025] With the development of technology, the functions of vehicle seats are becoming more and more abundant. For example, equipping vehicle seats with calf rests can be used to relieve the leg fatigue caused by long-term riding. At present, the seats with leg rests can be unfolded in a single way, but there are differences in body shapes between different users. Therefore, when different users sit on the seats and use the leg rests, they cannot achieve a comfortable posture, resulting in a poor user experience.

[0026] In order to solve the problems of the prior art, the embodiments of the present application provide a method, device, equipment, storage medium and vehicle for adjusting a seat. The method for adjusting a seat provided in the embodiments of the present application is first introduced below.

[0027] Figure 1 FIG. 1 is a flow chart of a method for adjusting a seat provided by an embodiment of the present application. Figure 1 As shown, a method for adjusting a seat, the seat includes a seat cushion and a leg rest, and the method may include the following steps S101 to S103.

[0028] S101, obtaining vital sign information of a target user sitting on a seat;

[0029] S102, determining the pressure sharing rate value corresponding to the physical sign information of the target user as the target sharing rate value of the seat, the pressure sharing rate value being the ratio of the first pressure to the second pressure, the first pressure being the pressure borne by the leg rest, and the second pressure being the total pressure borne by the seat cushion and the leg rest;

[0030] S103, controlling the leg rest of the seat to adjust until the share rate value of the seat is adjusted to the target share rate value.

[0031] The method for adjusting the seat of the embodiment of the present application can determine the pressure sharing rate value corresponding to the physical sign information of the target user as the target sharing rate value of the seat according to the physical sign information of the user sitting on the seat, and the pressure sharing rate value is the ratio of the first pressure to the second pressure, the first pressure is the pressure borne by the leg rest, and the second pressure is the total pressure borne by the seat cushion and the leg rest; and by adjusting the leg rest of the seat, the sharing rate value of the seat is adjusted to the target sharing rate value to increase the leg comfort of the target user. In this way, the embodiment of the present application can determine the target sharing rate value of the seat according to the physical sign information of the user, thereby adjusting the leg rest of the seat, and adjusting the sharing rate value of the seat to the target sharing rate value, so as to meet the adjustment of the leg comfort of users of different body shapes, thereby improving the user experience.

[0032] The specific implementation methods of the above steps are introduced below.

[0033] In S101 , the target user may be a user sitting on a seat.

[0034] The above-mentioned physical sign information may be used to characterize the physical characteristics of the target user, and may be, for example, the height and weight of the target user.

[0035] The above-mentioned acquisition of the vital sign information of the target user sitting on the seat may be, illustratively, that the target user inputs the vital sign information into a processing terminal of the seat.

[0036] In S102, the pressure sharing ratio value is the ratio of the first pressure to the second pressure, the first pressure is the pressure borne by the leg rest, and the second pressure is the total pressure borne by the seat cushion and the leg rest.

[0037] The above-mentioned determination of the pressure sharing rate value corresponding to the target user's vital sign information as the target sharing rate value of the seat can be that the pressure sharing curve corresponding to the target user's vital sign information is determined as the target pressure sharing curve of the seat in a preset pressure sharing curve library, the preset pressure sharing curve library includes different vital sign information and pressure sharing curves corresponding to each vital sign information, each pressure sharing curve is used to represent the curve of the pressure sharing of the seat cushion and the leg rest when users with different vital sign information sit on the seat and adjust the seat to a comfortable state; the pressure sharing rate value of the target pressure sharing curve is determined as the target sharing rate value of the seat. Alternatively, the pressure sharing rate value corresponding to the target user's vital sign information can be determined as the target sharing rate value of the seat in the preset corresponding relationship between the vital sign information and the pressure sharing rate value.

[0038] In some embodiments, the above S102 may specifically include:

[0039] In the preset pressure sharing curve library, the pressure sharing curve corresponding to the physical sign information of the target user is determined as the target pressure sharing curve of the seat. The preset pressure sharing curve library includes different physical sign information and pressure sharing curves corresponding to each physical sign information. Each pressure sharing curve is used to represent the pressure sharing curve of the seat cushion and the leg rest when users with different physical sign information sit on the seat and adjust the seat to a comfortable state;

[0040] The pressure sharing rate value of the target pressure sharing curve is determined as the target sharing rate value of the seat.

[0041] The preset pressure sharing curve library may include different physical information and pressure sharing curves corresponding to each physical information. Each pressure sharing curve may be used to represent the pressure sharing curve of the seat cushion and leg rest when a user with different physical information sits on the seat and adjusts the seat to a comfortable state.

[0042] In this embodiment, since users with different physical information sit on the seat and adjust the seat to a comfortable state, the pressure sharing curves of the seat cushion and the leg rest are different. The target pressure sharing curve is determined by the physical information of the target user, and the pressure sharing rate value of the target pressure sharing curve is calculated, so as to accurately obtain the target sharing rate value of the seat.

[0043] As an implementation of the present application, in order to obtain an accurate pressure sharing curve library, before determining the pressure sharing curve corresponding to the physical sign information of the target user in the preset pressure sharing curve library as the target pressure sharing curve of the seat, the following steps may also be included:

[0044] Acquire the vital sign information of a plurality of first users and a first pressure sharing curve corresponding to each first user, wherein the first pressure sharing curve is a curve of pressure sharing between a seat cushion and a leg rest when the first user sits on a seat and adjusts the seat to a comfortable state;

[0045] The abnormal pressure sharing curves in each pressure sharing curve group are removed to obtain each standard pressure sharing curve group, wherein the abnormal pressure sharing curve is the first pressure sharing curve in each pressure sharing curve group whose deviation exceeds a preset deviation threshold, and the pressure sharing curve group includes multiple first pressure sharing curves with the same vital sign information, and different pressure sharing curve groups correspond to different vital sign information;

[0046] Determine the average value curve or fitting curve of the first pressure sharing curve in each standard pressure sharing curve group as the pressure sharing curve of each standard pressure sharing curve group;

[0047] According to the pressure sharing curves of each standard pressure sharing curve group and the corresponding physical sign information, a preset pressure sharing curve library is constructed.

[0048] The first user may be a test user, and the first pressure sharing curve may, for example, be a curve that collects pressure values ​​shared by the seat cushion and the leg rest when the test user sits on the seat and adjusts the seat to a comfortable state, and converges them into the first pressure sharing curve.

[0049] The average value curve of the first pressure sharing curve in each of the above-mentioned standard pressure sharing curve groups may be an arithmetic average value curve.

[0050] The above-mentioned abnormal pressure sharing curves in each pressure sharing curve group are removed to obtain each standard pressure sharing curve group, and the average value curve or fitting curve of the first pressure sharing curve in each standard pressure sharing curve group is determined as the pressure sharing curve of each standard pressure sharing curve group. For example, it can be as follows Figure 2 As shown in the figure, the first pressure sharing curve of the seat cushion and the calf when the occupant adjusts to a comfortable sitting position by himself when collecting 100 identical physical signs information (i.e. Figure 2 The horizontal axis is the pressure collection point, and the vertical axis is the pressure sharing value. The data with large deviations are removed from the 100 groups of first pressure sharing curves, and the remaining curves are averaged or fitted to obtain the pressure sharing rate curve of the vital sign information (i.e. Figure 2 middle black line).

[0051] In some embodiments, the pressure value of each vehicle occupant can be collected through the pressure sensor pre-installed on the actual vehicle, and a real-time pressure sharing curve can be drawn. The preset pressure sharing curve library can be continuously updated and iterated through big data statistics.

[0052] In this embodiment, by removing the abnormal pressure sharing curves in each pressure sharing curve group to obtain each standard pressure sharing curve group, abnormal data can be eliminated and the pressure sharing curves of each standard pressure sharing curve group can be obtained more accurately. According to each pressure sharing curve and the corresponding vital sign information, a preset pressure sharing curve library can be accurately constructed.

[0053] In S103, the pressure sharing rate value of the seat is the real-time pressure sharing rate value of the target user sitting on the seat.

[0054] In some embodiments, the above-mentioned seat may further include a backrest;

[0055] The above S103 may specifically include:

[0056] When the backrest angle is determined, the target state parameter corresponding to the target user's physical sign information and the target sharing rate value is determined in the preset corresponding relationship, and the corresponding relationship is used to characterize the corresponding relationship between the pressure sharing rate value, the physical sign information and the state parameter of the leg support;

[0057] The leg support of the seat is adjusted to the target state parameter so that the share rate value of the seat is adjusted to the target share rate value.

[0058] The above-mentioned state parameters may be the unfolding angle and extension length of the leg rest.

[0059] The above correspondence can be used to characterize the corresponding relationship between the pressure sharing rate value, the physical sign information and the state parameters of the leg rest when the backrest angle is determined.

[0060] In this embodiment, when the backrest angle remains unchanged, in the preset corresponding relationship, the target state parameters corresponding to the target user's vital sign information and the target sharing rate value are directly determined and the leg rest is adjusted to quickly adjust the seat's sharing rate value to the target sharing rate value.

[0061] In some embodiments, the target state parameters may include a target deployment angle and a target extension length;

[0062] In the above-mentioned preset corresponding relationship, determining the target state parameter corresponding to the target user's vital sign information and the target sharing rate value may specifically include:

[0063] In the preset first sub-correspondence, a target deployment angle and / or a target extension length corresponding to the target user's vital sign information and the target sharing rate value is determined.

[0064] The corresponding relationship includes a first sub-corresponding relationship, and the first sub-corresponding relationship is used to characterize the corresponding relationship between the pressure sharing rate value, the physical sign information, and the unfolding angle and / or extension length of the leg rest.

[0065] The first sub-correspondence relationship can be obtained by fitting formula (1) according to the physical sign information of the plurality of first users, the pressure sharing rate value corresponding to the first pressure sharing curve, the unfolding angle and the extension length of the seat, which is specifically expressed as follows:

[0066] Z=k1*x+k2*y+k3*a+k4*b+k5 (1)

[0067] Among them, Z represents the pressure sharing rate value; x represents the unfolding angle of the leg rest; y represents the extended length of the leg rest; a represents the height in the physical sign information; b represents the weight in the physical sign information, and k1 to k5 are fitting coefficients.

[0068] In this embodiment, the target state parameters may include a target deployment angle and a target extension length, so that the leg comfort of the target user can be increased by adjusting the deployment angle and / or extension length of the leg rest of the seat.

[0069] In some embodiments, if the backrest angle changes, the above S103 may specifically include:

[0070] When the state parameter of the leg rest is adjusted according to the preset adjustment range for the i-th time, the share rate value of the seat is detected, where i is a positive integer;

[0071] If it is determined that the sharing rate value reaches the target sharing rate value, then the adjustment of the state parameters of the leg support is stopped;

[0072] If it is determined that the sharing rate value does not reach the target sharing rate value, i is updated to i+1, and the i-th adjustment of the state parameters of the leg rest according to the preset adjustment range is re-executed.

[0073] The preset adjustment range, for example, may be a preset adjustment angle of 5°, or a preset extension length of 5 cm. In this embodiment, the value of the preset adjustment range is not limited thereto, and may also be other values, which are not specifically limited here.

[0074] In this embodiment, the state parameters of the leg rest are adjusted according to a preset adjustment range until the detected seat sharing rate value reaches the target sharing rate value, then the adjustment of the state parameters of the leg rest is stopped. This allows the leg rest of the seat to be dynamically adjusted when the backrest angle changes, thereby increasing the leg comfort of the target user.

[0075] As another implementation of the present application, in order to adjust the leg comfort of the new user, before the above S101, the following steps may be further included:

[0076] Obtain a pressure distribution map of a target user sitting on the seat;

[0077] calculating a similarity between the pressure distribution map and each historical distribution map in at least one historical distribution map, each historical distribution map being a pressure distribution map of each second user sitting on the seat and using a leg rest;

[0078] The above S101 may specifically include:

[0079] When the similarities of the historical distribution graphs are all less than a preset threshold, the vital sign information of the target user sitting on the seat is obtained.

[0080] The above pressure distribution diagram, for example, can be a distribution diagram of the pressure on the seat cushion and the leg support when the target user sits on the seat for the third minute, such as Figure 3 As shown, the area of ​​rows 0-10 is the cushion area, and the area of ​​rows 13-23 is the calf area. The values ​​in the figure are pressure values. The pressure distribution diagram is not limited to the third minute, but can also be other moments, which is not specifically limited in this application.

[0081] The second user mentioned above may be, for example, a historical user who has used the seat and the leg rest.

[0082] The situation where the similarities of the above-mentioned historical distribution graphs are all less than the preset threshold value means that the target user is a new user different from the second user. Therefore, the seat leg rest can be adjusted according to the physical sign information of the target user.

[0083] In this embodiment, by calculating the similarity between the target user's pressure distribution map and each historical distribution map, it is determined whether the target user is a new user, so that the seat leg rest can be adjusted according to the target user's physical information to achieve adjustment of the new user's leg comfort.

[0084] As another implementation of the present application, in order to meet the personalized needs of old users, after calculating the similarity between the pressure distribution map and each historical distribution map in the at least one historical distribution map, the following may also be included:

[0085] Determine the historical distribution map whose similarity among the historical distribution maps is greater than or equal to a preset threshold as the target distribution map;

[0086] Determine the historical state parameters of the leg support corresponding to the target distribution diagram as the target state parameters;

[0087] Adjust the seat's leg rest to the target state parameters.

[0088] The above historical state parameters are state parameters for adjusting the seat leg rest to a state that the second user feels comfortable.

[0089] The similarity between the pressure distribution map and the historical distribution map is greater than or equal to a preset threshold, which means that the target user is a user of at least one second user, that is, the target user is an old user.

[0090] In this embodiment, the historical state parameters of the leg rest corresponding to the target distribution diagram are determined as the target state parameters, and the leg rest of the seat is directly adjusted to the target state parameters, which can meet the personalized needs of old users.
