Based on the above terminal device architecture, but not limited to the above architecture, the method embodiments of the present application are presented.

Referring to fig. 3, fig. 3 is a flow chart illustrating an exemplary embodiment of a method for adjusting a vehicle seat according to the present application. The vehicle seat adjustment method of the embodiment includes:

in step S101, a thermal image of a target occupant is acquired by a thermal imaging apparatus.

In one embodiment, the terminal device may activate the seat adjustment function upon detecting a person on the seat, thereby triggering the thermal imaging device to capture a thermal image of the target occupant.

In another embodiment, the terminal device may start the seat adjusting function after receiving a seat adjusting start instruction sent by the user through the mobile terminal APP or voice, so as to trigger the thermal imaging device to collect a thermal image of the target occupant.

Wherein the target occupant may be any one of a plurality of occupants (including a driver and a passenger) on the vehicle. The target occupant may include one or more.

Among them, a thermal imaging apparatus is an apparatus that generates a thermal image by non-contact detection of infrared energy (heat) and conversion thereof into an electrical signal. The thermal imaging apparatus may be mounted at one or more preset positions on the vehicle, and thermal images corresponding to respective occupants (including drivers and passengers) on the vehicle may be captured through the one or more preset positions.

Further, after the thermal image is acquired, preliminary processing may be performed on the thermal image, such as removing noise, adjusting contrast, to optimize the image quality of the thermal image.

Step S102, determining the body temperature of the target portion corresponding to the target occupant based on the thermal image.

The thermal image acquired by the thermal imaging device comprises a temperature value of each pixel point in the thermal image, so that body temperature distribution data of a target passenger can be acquired through the thermal image, and temperature differences of various body parts of the target passenger can be determined through the body temperature distribution data.

The terminal device may acquire body temperature distribution data of each target area from the body temperature distribution data, where the target area may be an area in contact with the seat. For example, the target area may include a back area and a hip area of the target occupant.

After acquiring the body temperature distribution data of each target area, the terminal device can determine the body temperature of each target part according to the body temperature distribution data of each target area. Specifically, the terminal device may calculate the average temperature of all the pixel points corresponding to each target area, obtain the average temperature corresponding to each target area, and use the average temperature corresponding to each target area as the body temperature of each target portion.

Step S103, determining the target power of the target temperature regulating system based on the body temperature of the target part, and controlling the target temperature regulating system to operate at the target power until the temperature of the target seat meets the preset temperature comfort condition.

The target temperature adjusting system is a temperature adjusting system corresponding to the target seat. The target seat is a seat on which a target occupant sits.

In this embodiment, each seat includes a temperature adjustment system corresponding to each seat. The target temperature adjustment system for the target seat may include one or more heating modules and one or more ventilation modules. The one or more heating modules may be distributed at a plurality of different locations on the target seat, and the one or more ventilation modules may be distributed at a plurality of different locations on the target seat.

In this embodiment, the above temperature comfort condition may include: the temperature of each seat contact area corresponding to the target seat is an ideal temperature value corresponding to each seat contact area, and the ideal temperature value corresponding to each seat contact area can be preset for each passenger and stored in a database; if the occupant does not preset the ideal temperature value corresponding to each seat contact area, acquiring the preset default comfort temperature value corresponding to each seat contact area from the database as the ideal temperature value corresponding to each seat contact area. Each seat contact area may be correspondingly provided with a temperature sensor for detecting a corresponding temperature of each seat contact area.

Accordingly, in this embodiment, the step of determining the target power of the target temperature adjustment system based on the body temperature of the target portion and controlling the target temperature adjustment system to operate with the target power until the temperature of the target seat meets the preset temperature comfort condition may include:

as an embodiment, the terminal device may calculate the absolute value of the difference between the body temperature of each target portion and the ideal temperature value of the seat contact area corresponding to each target portion, obtain the absolute value of the difference between each seat contact area, determine the target power of the heating module or the ventilation module disposed in each seat contact area based on the absolute value of the difference between each seat contact area, and control each heating module or each ventilation module to operate at the corresponding target power. Wherein, each target part corresponds to each seat contact area one by one, for example, the target part is the back, and the corresponding seat contact area is the chair back of the chair; the target part is buttocks, and the corresponding seat contact area is the cushion of the seat. The absolute value of the difference in the respective contact areas can be understood as: if the back body temperature of the target occupant is T1 and the ideal temperature value of the seat back is T2, the absolute value of the difference value of the seat back is |T1-T2|.

The target power of each heating module may be determined based on a pre-established correspondence between the absolute value of the difference and the target power of the heating module, and the target power of each ventilation module may be determined based on a pre-established correspondence between the absolute value of the difference and the target power of the ventilation module.

Further, if the body temperature of the target portion is greater than the ideal temperature value of the seat contact area corresponding to the target portion, after determining the absolute value of the difference value of the seat contact area corresponding to the target portion, controlling the ventilation module in the seat contact area corresponding to the target portion to operate at the corresponding target power until the temperature of the seat contact area corresponding to the target portion reaches the corresponding ideal temperature value. And if the body temperature of the target part is smaller than the ideal temperature value of the seat contact area corresponding to the target part, after determining the absolute value of the difference value of the seat contact area corresponding to the target part, controlling the heating module in the seat contact area corresponding to the target part to operate at the corresponding target power until the temperature of the seat contact area corresponding to the target part reaches the corresponding ideal temperature value.

In another embodiment, the terminal device may calculate the absolute value of the difference between the body temperature of each target portion and the ideal temperature value of the seat contact area corresponding to each target portion, obtain the absolute value of the difference of each contact area, and determine the target power of the heating module or the ventilation module disposed in each seat contact area based on the absolute value of the difference of each seat contact area and the current ambient temperature. Wherein the current ambient temperature may include a current in-vehicle ambient temperature and/or a current out-of-vehicle ambient temperature.

The target power of each heating module may be determined according to the desired adjustment time T, the absolute value of the difference a, and the current ambient temperature Te, specifically, the target power f of each heating module is determined by a function Z (f 1) = (T, a, te). Wherein Z (f 1) is a related function with respect to the desired conditioning time t, the temperature difference a and the current ambient temperature Te and the target power f1 of the heating module. The target power of each ventilation module may also be determined from the desired conditioning time T, the temperature difference a and the current ambient temperature Te, in particular by the function U (f 2) = (T, a, te) the target power f2 of each ventilation module. Where U (f 2) is a related function with respect to the desired conditioning time t, the difference a and the current ambient temperature Te and the target power f2 of the ventilation module.

Based on the above embodiment, in the case where the temperature comfort condition includes that the temperature of each seat contact area of the target seat is the ideal temperature value corresponding to each seat contact area, the step of determining the target power of the target temperature adjustment system based on the body temperature of the target site may further include:

the identity of the target occupant is identified.

If the seat temperature comfort values corresponding to the seat contact areas corresponding to the target occupant identities are found in the database, the seat temperature comfort values corresponding to the seat contact areas are used as ideal temperature values corresponding to the seat contact areas;

and if the seat temperature comfort values corresponding to the seat contact areas corresponding to the target occupant identities are not found in the database, acquiring default comfort temperature values corresponding to the seat contact areas as ideal temperature values corresponding to the seat contact areas.

Specifically, the terminal device may collect a face image of an occupant through an image collecting device (e.g., a thermal imaging device), identify features of the face image through a neural network, and match corresponding occupant identity faces in a face image feature library through the features of the face image, so as to obtain information of the corresponding identity occupant and the corresponding identity occupant, where the information may include an occupant ID, a height, an age, a sex, a weight, and the like.

Further, the step of controlling the target temperature adjustment system to operate at the target power until the temperature of the target seat satisfies the preset temperature comfort condition may further include:

and after the received configuration instruction or update instruction is responded, acquiring the configuration instruction or update quality-contained seat parameter configuration information, and generating or updating a target seat parameter configuration table based on the seat parameter configuration information.

In this embodiment, the vehicle central control screen may provide a seat parameter configuration interface, and the target occupant may execute a feedback result for the current seat adjustment on the central control screen, where the feedback result may include a target seat parameter target value that the target occupant selects to adjust to, and submit the feedback result through a submit button of the seat parameter configuration interface to trigger generation of a configuration instruction or an update instruction. For example, in the adjustment, the terminal device adjusts the temperature of the seat to 26 degrees of imaging, the target occupant can adjust the temperature of the seat to 28 degrees of imaging through the seat parameter configuration interface, and at the same time, the terminal device updates the target seat parameter configuration table in response to the feedback result so as to set the ideal temperature value of the seat corresponding to the target occupant to 28 degrees of imaging. Of course, in other embodiments, the feedback result may be generated by the target occupant by clicking the seat physical adjustment button, while triggering generation of the update command. Or the feedback result is submitted and generated by a target passenger through a seat parameter configuration interface of the mobile terminal APP.

According to the scheme of the embodiment, the sensitivity of each passenger to the body feeling is considered to be different, the preference of different passengers to the seat temperature is different, different ideal seat temperature values are supported to be set by different passengers, personalized configuration is realized, and each passenger can obtain optimal comfort level. Meanwhile, by providing the seat parameter configuration interface for interaction with the user, the user can configure or update the seat parameters through the seat parameter configuration interface, so that the usability is high, and the interaction experience is friendly.

Referring to fig. 4, fig. 4 is a flow chart illustrating a method for adjusting a vehicle seat according to another exemplary embodiment of the present application. Compared to the above embodiment, the present embodiment may further include:

step S201, determining the degree of back bending of the target occupant based on the thermal image.

Specifically, the thermal image acquired by the thermal imaging apparatus contains contour information of the target occupant. Referring to fig. 5, fig. 5 is a thermal image of a target occupant according to an embodiment of the present application, and as can be seen from fig. 5, the thermal image acquired by the thermal imaging device includes contour information of the target occupant, so that the terminal device can identify the contour of the target occupant in the thermal image through an artificial intelligent algorithm such as a neural network or a decision tree, and extract a back curve belonging to the back, then select a target location point in the back curve, calculate a tangential tilt angle corresponding to the target location point, and characterize the back bending degree of the target occupant through the tangential tilt angle corresponding to the target location point. For example, if the tangential tilt angle corresponding to the target position point is equal to 0, which indicates that the back bending degree of the target occupant is 0 at this time, it is further possible to determine that the current sitting posture of the target occupant on the target seat is upright.

Step S202, adjusting the inclination of the seat based on the degree of back bending.

Specifically, the terminal device may obtain a preset correspondence between the back bending degree and the inclination of the seat from the target seat parameter configuration table, and adjust the inclination of the seat. Wherein the correspondence may be preset for the target occupant or set based on ergonomic criteria. For example, at a back curve level of 0, the seat tilt is set to 0 to provide better spinal support to the target occupant, particularly under the back, to accommodate spinal pressure from an upright sitting position. For another example, when the target occupant sits on the target seat in an inclined sitting position, the degree of back bending of the target occupant detected at this time is 110 degrees, and the seat inclination is set to 110 degrees to accommodate the relaxed sitting position, particularly to accommodate the natural bending of the waist and back.

Further, after the terminal device adjusts the inclination of the seat, the terminal device may respond to the feedback result of the current adjustment of the inclination of the seat by the terminal device submitted by the target occupant through the vehicle central control interface, or the mobile terminal APP interface and the target seat physical adjustment button, where the feedback result may include the inclination of the seat selected by the target occupant to be adjusted, and update the correspondence between the back bending degree and the inclination of the seat based on the inclination of the seat selected by the target occupant to be adjusted.

According to the technical scheme, the back bending degree of the target passenger is determined based on the thermal image, and the inclination of the seat is adjusted based on the back bending degree of the target passenger, so that the inclination of the seat can be matched with the natural curve of the back of the passenger, the spine pressure of the passenger during riding can be reduced, and the riding comfort of the passenger can be improved.

Turning to fig. 6, fig. 6 is a flow chart illustrating a method of adjusting a vehicle seat according to yet another exemplary embodiment of the present application. Compared to the above embodiment, the present embodiment may further include:

step S301, determining the hip-to-knee distance of the target occupant based on the thermal image.

Specifically, after the thermal image is acquired, the terminal device can identify the outline of the target occupant in the thermal image through an artificial intelligent algorithm such as a neural network or a decision tree, identify the buttocks and knees of the occupant through an artificial intelligent algorithm such as a neural network or a decision tree, position the rearmost end of the buttocks and the foremost end of the knees of the target occupant on the thermal image, calculate the image distance between the rearmost end of the buttocks and the foremost end of the knees on the thermal image, and determine the distance from the buttocks of the target occupant to the knees based on the proportion of the thermal image and the image distance. For example, if the ratio of the thermal images is 1/100 and the image distance is A, the distance from the buttocks to the knees of the target occupant is A/(1/100).

Step S302, the seating depth of the target seat is adjusted based on the distance.

Specifically, the terminal device may acquire a corresponding relationship between a preset distance and a seating depth from the target seat parameter configuration table, and adjust the seating depth of the seat based on the corresponding relationship. Wherein the correspondence may be preset for the target occupant or set based on ergonomic criteria. For example, according to ergonomic principles, the ideal seating depth for each distance is calculated so that the knees of the occupant are just at the edge of the seat, but without a sense of compression.

Further, after adjusting the seating depth of the target seat, the terminal device may respond to a feedback result of the seating depth adjusted by the target seat through the vehicle central control interface, or the mobile terminal APP interface and the target seat physical adjustment button, where the feedback result may include the seating depth adjusted by the target seat selected by the target seat occupant, and update the correspondence between the distance in the target seat parameter configuration table and the seating depth based on the seating depth adjusted by the target seat selected by the target seat occupant.

According to the technical scheme, the distance from the buttocks to the knees of the target seat is determined through the thermal image, and the sitting depth of the target seat is adjusted based on the distance, so that the position of the knees of the seat is matched with the edge of the seat when the seat is ridden, and the riding comfort of the seat is improved.

Turning to fig. 7, fig. 7 is a flow chart illustrating a method of adjusting a vehicle seat according to still another exemplary embodiment of the present application. In contrast to the above-described embodiments, the seat of the present embodiment includes a lumbar support, and the vehicle seat adjustment method may further include:

step S401, determining the lumbar curve curvature of the target occupant based on the thermal image.

Specifically, the terminal device can identify the outline of the target passenger in the thermal image through a neural network or an artificial intelligent algorithm such as a decision tree and the like, extract a waist curve belonging to the waist, select a target waist position point in the waist curve, calculate the curvature corresponding to the target waist position point, and represent the curvature of the waist curve of the target passenger through the curvature corresponding to the target position point. For example, if the curvature corresponding to the target position point is equal to 0, which means that the lumbar curve curvature of the target occupant is 0 at this time, it is further possible to determine that the current sitting posture of the target occupant on the target seat is upright. The target waist position point can be selected according to actual conditions.

Step S402, adjusting the height and the supporting depth of the lumbar support based on the curvature of the lumbar curve.

In particular, the seat on the vehicle of the embodiments of the present application may further include a lumbar support, the height and the support depth of which are set to be adjustable. The height of the lumbar support refers to the height of the lumbar support in the vertical direction of the seat back portion, namely the height relative to the seat cushion. The support depth of the lumbar support refers to the extent to which the lumbar support protrudes forward, i.e., the distance it protrudes from the back of the seat toward the lumbar region of the occupant.

In this embodiment, the terminal device may obtain a corresponding relationship between a preset lumbar curve curvature and a lumbar support height and a lumbar support depth from the target seat parameter configuration table, and adjust the lumbar support height and the support depth of the target seat based on the corresponding relationship.

Further, the terminal equipment can also combine the waist temperature distribution data and the curvature of the waist curve in the thermal image to adjust the height and the supporting depth of the waist support. Since the portion of the body of the target occupant in contact with the seat will typically have a different thermal profile, the lumbar pressure profile may be analyzed by lumbar temperature profile data, e.g., a hotter region may indicate greater pressure therein. Then, the terminal device may determine that the pressure of the partial area is greater than a preset pressure threshold value based on the lumbar temperature distribution data if the temperature of the partial area in the lumbar temperature distribution data is greater than the preset temperature threshold value, calculate a temperature average value of the partial area, and then adjust the support depth of the target seat based on a corresponding relationship between the preset temperature average value and the lumbar support depth. The height of the lumbar support can be determined based on the corresponding relation between the curvature of the preset lumbar curve and the supporting height of the lumbar support.

Further, after adjusting the height and the supporting depth of the lumbar support of the target seat, the terminal device may respond to the feedback result of the height and the supporting depth of the lumbar support adjusted by the terminal device through the vehicle central control interface, or the mobile terminal APP interface and the target seat physical adjustment button, where the feedback result may include the height and the supporting depth of the lumbar support selected and adjusted by the target seat occupant, and update the corresponding relationship between the curvature of the lumbar curve and the height and the supporting depth of the lumbar support in the target seat parameter configuration table based on the height and the supporting depth of the lumbar support selected and adjusted by the target seat occupant.

According to the technical scheme, the lumbar curve curvature of the target passenger is determined through the thermal image of the target passenger, and the height and the supporting depth of the lumbar support of the target seat are adjusted based on the lumbar curve curvature, so that the comfort level of the passenger is improved, and meanwhile, the lumbar fatigue and discomfort caused by long-time riding can be reduced.

Referring to fig. 8, fig. 8 is a flow chart illustrating a vehicle seat adjustment method according to still another exemplary embodiment of the present application. Compared to the above embodiment, the present embodiment may further include:

Step S501, based on the thermal image, determines the relative position of the head of the target occupant with respect to the headrest.

Specifically, the thermal imaging map includes a body region of the target occupant and a seat portion in contact with the body, including a headrest region. Therefore, the terminal equipment can identify the outline of the target passenger and the outline of the headrest in the thermal image through a neural network or a decision tree and other artificial intelligent algorithms to obtain the head position of the target passenger and the headrest position of the target seat, and then the terminal equipment can determine the relative position of the head of the target passenger relative to the headrest based on the head position of the target passenger and the headrest position of the target seat.

Step S502, the height of the headrest is adjusted based on the relative position.

The terminal device may acquire a correspondence between the head relative position and the headrest adjustment height from the target seat parameter configuration table, and adjust the height of the headrest based on the correspondence. For example, assuming that the relative position of the head of the target occupant with respect to the headrest is that the head midpoint position is lower by 2cm in the headrest vertical direction with respect to the head midpoint position, the headrest adjustment height is determined to be 2cm higher in the headrest vertical direction.

Step S503, determining the back bending degree of the target occupant based on the thermal image.

The implementation principle of determining the back bending degree in this embodiment is consistent with that of the foregoing embodiment, and the specific implementation process refers to the foregoing related content and is not repeated herein.

Step S504 adjusts the pitch angle of the headrest based on the degree of back bending.

The pitching angle of the headrest refers to the inclination angle of the headrest relative to the back of the seat. The terminal device may acquire a correspondence between the back bending degree and the headrest pitch angle from the target seat parameter configuration table, and adjust the pitch angle of the headrest based on the correspondence. The correspondence may be determined based on ergonomic principles, for example, when the degree of back bending is tilting, where the headrest pitch angle needs to be greater than 90 degrees (backward tilt angle); when the degree of back bending is upright, the headrest pitch angle may be set to 90 degrees (upright angle).

Further, after the height and the pitching angle of the headrest are adjusted, the terminal device may respond to a feedback result of the height and the pitching angle of the headrest adjusted by the terminal device through the vehicle central control interface, or the mobile terminal APP interface and the target seat physical adjustment button, where the feedback result may include the height and the pitching angle of the headrest adjusted by the target occupant, and update the correspondence between the head relative position and the headrest adjustment height in the target seat parameter configuration table, and the correspondence between the back bending degree and the headrest pitching angle based on the height and the pitching angle of the headrest adjusted by the target occupant.

According to the scheme, the relative position of the head of the target passenger relative to the headrest is determined through the thermal image, then the height of the headrest is adjusted based on the relative position, the back bending degree of the target passenger is determined based on the thermal image, and then the pitching angle of the headrest is adjusted based on the back bending degree, so that the height and the pitching angle of the pillow are adapted to different sitting postures of the passenger, the head and the neck of the passenger are properly supported, and neck fatigue and discomfort caused in long-distance driving can be relieved.

Referring to fig. 9, fig. 9 is a flowchart illustrating a vehicle seat adjustment method according to still another exemplary embodiment of the present application. In contrast to the above-described embodiments, the target seat of the present embodiment includes the side wings, and the support positions and the support strengths of the side wings are adjustable. The present embodiment may further include:

step S601, determining contact points of the body of the target occupant and the side wings and temperature values corresponding to the respective contact points based on the thermal image.

Specifically, the thermal imaging map includes a body region of the target occupant and a seat portion region of the target seat that is in contact with the body of the target occupant, including a region that is in contact with the side wings. The terminal equipment can identify the body of the target passenger and the side wings of the seat in the thermal image through a neural network or an artificial intelligent algorithm such as a decision tree and the like, and obtain an area where the body area of the target passenger and the side wing area of the seat are overlapped, wherein each pixel point in the repeated area is the contact point of the body of the target passenger and the side wings, and because each pixel point has a corresponding temperature value, the terminal equipment can simultaneously determine the temperature value corresponding to each contact point.

Step S602, determining the pressure corresponding to each contact point based on the temperature value corresponding to each contact point, and determining the contact degree of the target occupant with the side wings based on the pressure corresponding to each contact point.

Specifically, the terminal device may obtain a preset correspondence between a temperature value and a pressure value from the database, and determine the pressure of each contact point based on the correspondence. Alternatively, the terminal device may be based on a function p=f (T), where P represents the pressure of each contact point, T represents the temperature value corresponding to each contact point, f () is a function of the temperature value and the pressure, and determine the pressure of each contact point based on the function p=f (T).

After the terminal device obtains the pressure of each contact point, the average value of the pressures of all the contact points can be calculated, and according to the average value of the pressures of all the contact points, the corresponding relation between the preset average value of the pressures and the contact degree of the side wing, the contact degree of the target passenger and the side wing is determined. For example, if the pressure average is in the first pressure range, determining that the flank contact is strong; for another example, if the pressure average is in the second pressure range, the flank contact level is determined to be a stronger contact. Wherein, the first pressure range and the second pressure range are determined according to actual conditions.

Step S603, adjusting the support position and the support strength of the side wing based on the position and the contact degree of each contact point.

In vehicle seat design, the adjustment of the side wings generally involves two main aspects: the strength of the support and the support position. These adjustments may be accomplished by different mechanisms, including an inflator and an electric adjustment mechanism. In particular, a vehicle seat may use an inflator to adjust the support strength of the side wings by increasing or decreasing the amount of air in the inflator. Still alternatively, the vehicle seat may use electromechanical means to adjust the support strength and position of the side wings. Because the adjusting structure of the side wings is the prior art, the description is omitted here.

The support position of the side wings refers to a position of the seat side wings in a horizontal direction or a vertical direction for supporting the waist or chest of the occupant. The support strength of the side wings refers to the support pressure provided by the seat side wings to the occupant.

After determining each contact point, the terminal device may analyze the relative position of each contact point with respect to the entire body of the target occupant based on the thermal image, to obtain the position of each contact point. Then, a contact position range is determined based on the positions of the respective contact points, and the support position of the side wing is adjusted to a support position corresponding to the current contact position range based on the correspondence between the preset contact position range and the support position of the side wing. Meanwhile, the terminal equipment can adjust the supporting strength of the side wings based on the corresponding relation between the preset contact degree and the supporting strength of the side wings.

Further, after adjusting the supporting strength and supporting position of the side wing, the terminal device may respond to feedback information of the supporting strength and supporting position of the side wing submitted by the target occupant through the vehicle central control interface, or the mobile terminal APP interface and the physical button of the target seat, where the feedback information includes the supporting strength and supporting position of the side wing selected by the target occupant to be adjusted, and update the corresponding relationship between the contact position range and the supporting position of the side wing, and the corresponding relationship between the contact degree and the supporting strength of the side wing based on the supporting strength and supporting position of the side wing selected by the target occupant to be adjusted.

According to the technical scheme, the contact points of the body of the target passenger and the side wings and the temperature values corresponding to the contact points are determined through the thermal images, the pressure corresponding to the contact points is determined based on the temperature values corresponding to the contact points, so that the contact degree of the target passenger and the side wings is determined based on the pressure corresponding to the contact points, and then the supporting positions and the supporting strength of the side wings are adjusted based on the positions and the contact degrees of the contact points, so that the passenger can be supported more appropriately, discomfort in lateral movement is reduced, and the overall riding comfort of the passenger is improved.

Referring to fig. 10, fig. 10 is a flowchart illustrating a vehicle seat adjusting method according to still another exemplary embodiment of the present application. Compared to the above embodiment, the present embodiment may further include:

in step S701, based on the temperature value corresponding to each pixel in the thermal image, the pressure corresponding to each pixel is determined.

Specifically, the terminal device may obtain a correspondence between the temperature value and the pressure value from the database, and determine the pressure of each pixel point based on the correspondence. Alternatively, the terminal device may determine the pressure of each pixel point based on a function p=f (T), where P represents the pressure of each pixel point, T represents a temperature value corresponding to each pixel point, and f () is a function of the temperature value and the pressure.

Step S702, determining the fatigue part of the target occupant and the pressure corresponding to the fatigue part based on the pressure corresponding to each pixel point.

The terminal device may identify each portion of the target occupant based on the thermal image, and calculate an average value of pressures of all pixel points in each portion as the pressures of each portion, and determine a portion whose average pressure is greater than a preset fatigue pressure threshold as a fatigue portion. For example, the fatigue site may be the waist.

Step S703 of adjusting the massage mode of the target seat based on the fatigue part and the pressure corresponding to the fatigue part.

The terminal device may adjust the massage mode of the target seat based on the fatigue portion, the correspondence between the pressure corresponding to the fatigue portion and the seat massage mode. The correspondence may be set according to actual situations. The massage mode may include a kneading, tapping or mixing mode, and the kneading mode may include a gentle, medium or strong massage of various grades.

Further, after the massage mode of the seat is adjusted, the terminal device may respond to feedback information of the massage mode adjusted by the terminal device submitted by the target occupant through the vehicle central control interface, or the mobile terminal APP interface, and the seat massage adjustment button, where the feedback information includes the massage mode selected by the target occupant to be adjusted, and update the correspondence between the fatigue portion and the pressure corresponding to the fatigue portion and the seat massage mode based on the massage mode selected by the target occupant to be adjusted.

According to the scheme, the pressure corresponding to each pixel point is determined based on the temperature value corresponding to each pixel point in the thermal image, the fatigue part of the target passenger and the pressure corresponding to the fatigue part are determined based on the pressure corresponding to each pixel point, and then the massage mode of the target seat is adjusted based on the fatigue part and the pressure corresponding to the fatigue part. The massage device can provide massage functions for the passengers, and can adjust the massage modes based on the pressure corresponding to each fatigue part, so that the optimal relaxing effect of the passengers can be provided.

Based on the above embodiment, the vehicle seat adjustment method of the present example may further include:

step a1, determining the body shape of the target occupant based on the thermal image.

Specifically, the terminal device may recognize the contour of the target occupant based on the thermal image, determine the area of the target occupant based on the contour of the target occupant, and determine the body shape of the target occupant based on the area.

The terminal device may determine whether the body type of the target occupant belongs to a small, medium or large size based on a preset correspondence between the occupant area and the body type.

And a step a2 of adjusting the seat parameters of the target seat based on the body type. The seat parameters may include, among other things, seating depth and seat height.

For example, for small passengers, a small sitting depth point is provided to avoid suspending the legs and a small seat height is provided. For medium passengers, the seating depth is set at the neutral position and the seat height is at the default position. For large passengers, the seat depth is set to be a little greater and the seat height is set to be a little lower to provide more support and comfort.

According to the scheme, the body types of the passengers are classified based on the thermal images, and the parameters of the seat are adjusted based on the body types, so that the running mode of the seat is suitable for the passengers with different body types, and the riding comfort of the passengers can be improved.

Based on the above embodiment, the vehicle seat adjustment method of the present embodiment may further include:

and b1, determining the body shape or height of the target occupant.

The implementation manner of determining the height of the target occupant according to the embodiment may be: the terminal device may search the height of the corresponding identity occupant from the database after identifying the identity information of the occupant. Alternatively, the terminal device may obtain the height of the occupant by acquiring the occupant sitting position (i.e., the height difference between the highest position of the head top of the occupant and the position of the seat when the occupant sits on the seat) captured by the thermal image, and analyzing the occupant based on the phantom and the sitting position.

The implementation manner of determining the body shape of the target occupant in this embodiment may refer to the relevant content of step a1 in the above embodiment, and will not be described herein.

And b2, if the front road has an ascending slope or a descending slope, acquiring the ascending slope or the descending slope and acquiring the running speed of the vehicle.

In this embodiment, the terminal device may locate the current vehicle position, and detect, in combination with the map information, the topographic information of the road ahead of the current vehicle position, so as to determine whether there is an uphill slope or a downhill slope on the road ahead of the current vehicle position. If the front road has an ascending slope or a descending slope, the ascending slope or the descending slope of the front road is acquired based on the map information. The upward gradient or the downward gradient may be expressed in degrees, and α represents the upward gradient as shown in fig. 11.

And b3, adjusting the height of the seat based on the height/body type, the running speed and the downhill gradient of the target occupant, or adjusting the height of the seat based on the height/body type, the running speed and the uphill gradient of the target occupant.

In this embodiment, the implementation scheme of adjusting the height of the seat based on the height/body type, the traveling speed and the ascending slope of the target occupant may be:

searching a seat height value corresponding to the height/body type of the target passenger from a database to obtain an initial seat height;

determining the distance travelled by the vehicle in each unit time according to the corresponding travelling speed in each unit time;

determining the height of the ramp where the vehicle is located in each unit time according to the distance travelled by the vehicle in each unit time and the ascending slope;

correcting the initial seat height based on the ramp height of the vehicle in each unit time to obtain a target seat height corresponding to each unit time;

and adjusting the height of the seat to the target seat height corresponding to each unit time according to the unit time.

For example, assuming that the vehicle enters the uphill road at time T0, the vehicle travels Vi (i is greater than or equal to 1 and i is less than n, n being the total length of time the vehicle travels on the uphill road) at time Ti, the vehicle travels on the uphill road at time Ti by a distance L _i =t1+v1+ … +ti+vi+, then the following formula can be combined according to the uphill gradient α: hti =lti×sin α gives the ramp height hti at which the vehicle is located at each moment. Assuming that the seat height value corresponding to the height/body type of the target occupant is H0, since the vehicle is on an ascending slope, the terminal device reduces the height of the seat based on the original seat height value H0 so that the target occupant can obtain a better view on the ascending slope, and thus, the following formula H can be used _{Adjustment of} ti=h0-hti ×q to adjust the height of the seat; wherein q is a preset proportion. If the vehicle enters a downhill path, the vehicle can pass through H _{Adjustment of} ti=h0+ hti q adjusts the height of the seat.

For the scene of the downhill slope, the principle of realizing the adjustment of the seat height is consistent with that of the uphill slope, and the content of the uphill slope can be specifically referred to, which is not repeated herein.

In another embodiment, if there is no upward or downward slope on the road ahead, the seat height corresponding to the target occupant height/body shape is acquired from the database, and the seat height is adjusted to the corresponding seat height.

By the scheme of the embodiment, the seat height is adaptively adjusted by combining the scene that the road has an ascending slope and a descending slope and considering the ascending slope and the descending slope, so that an occupant can have enough view when the vehicle passes through the ascending slope and the descending slope.
