Description

TECHNICAL FIELD

[0001] The present application relates to the field of automobile interaction, and in particular to an interaction method and system of an automobile massage seat. BACKGROUND

[0002] With the improvement of people's living standards and the enhancement of health awareness, long-time driving or riding in a car can easily lead to physical fatigue and discomfort, so the market demand for pneumatic automobile massage seats with massage function is increasing. With the maturity of technology and the reduction of cost, pneumatic automobile massage seats are expected to become standard equipment for cars, further promoting market popularization.

[0003] In order to improve the comfort of users, interaction between people and seats needs to be realized. In the prior art, buttons are usually provided on the seat, and users interact by controlling the buttons. However, in the current situation where intelligent technology has made great progress, such button interaction not only has high cost and affects the overall appearance of the seat, but also has the defects of complicated and inconvenient operation, which reduces the intelligence, convenience and safety of the whole car.

[0004] Therefore, how to better interact between the automobile massage seat and the person is an important problem. In this background, human-computer interaction technology is attracting more and more attention and has become one of the focuses of intelligent automobile research. Human-computer interaction can be realized by various means, such as voice recognition, gesture recognition, screen touch, etc. However, these technologies have some shortcomings, such as: voice recognition is not very ideal in terms of speed and response in a scene with frequent control operations; gesture recognition requires users to learn gesture operations in advance; in a driving scene, screen touch operation on the screen has driving risks. As for the interaction with the automobile massage seat, due to the possible changes in human posture, these technologies have more limitations, such as when the seat is in a "zero gravity" state, the human body is in a lying posture, which affects the operation of buttons, panels, etc. If the response speed of voice recognition is also not ideal, the user needs to get up to interact, which is very inconvenient and seriously affects the user experience.

[0040] The present invention will be further described below through specific embodiments.

[0041] like Figure 1 As shown, the interaction method of the car massage seat includes the following steps:

[0042] Step S1: Use the air pressure detection device to detect the pressure of each airbag 2 in real time and send the pressure to the main control board. The main control board calculates the pressure distribution on the car massage seat based on the pressure of each airbag 2 and determines the current posture of the human body accordingly. The current posture of the human body includes sitting, lying down or sitting up.

[0043] like Figure 2 and Figure 3 As shown, the car massage seat 1 is equipped with multiple airbags 2, each airbag 2 is connected to a pressure sensor 3, and the airbag 2 is also connected to an intake valve 4, a pressure holding valve 5, a pressure relief valve 7, an air inlet 6, and an air outlet 8. The connection structure between the airbag 2 and the intake valve 4, pressure holding valve 5, pressure relief valve 7, air inlet 6, and air outlet 8 is existing technology. Specifically, the car massage seat 1 includes a seat cushion 11, a leg rest located at the lower end of the seat cushion 11, and a backrest 12 rotatably mounted on the seat cushion 11. Multiple airbag groups are arranged parallel and spaced from the upper end of the backrest 12 to the front end of the seat cushion 11, and each airbag group includes two airbags 2 of the same size. These airbag groups are positioned corresponding to the seating and leaning areas of the seat where the passenger sits and leans, and are spaced to cover the length and width of the seating and leaning areas to fully support the passenger, collect the pressure data of the passenger on the airbags 2, and thus determine the passenger's sitting posture.

[0044] When in operation, the user only presses one air bag 2 in the air bag group, and the main control board determines whether the pressure value change on the one air bag 2 is the interactive instruction from the human body according to the real-time pressure change of the two air bags 2 in the air bag group. The reason for such arrangement is that the two air bags 2 in one air bag group are arranged in parallel, and the parts of the human body are the same, and the pressure received is also the same when normally sitting. At this time, the user presses one air bag 2, and the pressure change of the one air bag 2 relative to the other air bag 2 is significant, so that the main control board can subtract the pressure value change of the other air bag 2 from the pressure value change of the one air bag 2 to accurately calculate the size and duration of the pressure pressed by the user, and then determine whether the pressure value change is the interactive instruction from the human body according to the size and duration of the pressure pressed by the user. In this way, even if the car is bumpy during driving, since the air bag group is subjected to the same bump, the subtraction of the two can accurately determine whether the user presses one air bag 2.

[0045] As shown in Figure 4 , all air bag groups are divided into upper air bags 2 (top1-topN) and lower air bags 2 (bottom1-bottomN), the upper air bags 2 include the air bags 2 from the head to the lower end of the backrest 12, and the lower air bags 2 include the air bags 2 from the rear end of the seat cushion 11 to the front end of the seat cushion 11.

[0046] The air pressure detection module is as shown in Figure 5 , when the pressure is stable and the inlet valve 4 and the pressure maintaining valve 5 are closed, the pressure sensor 3 (WF100SPZ) collects the pressure data of the air bag 2, the filter circuit transmits the collected pressure data to the back-end analog-to-digital conversion chip HX710B for amplification collection and conversion into a digital signal, and the digital signal is sent to the MCU for analysis and conversion into an AD value (analog-to-digital conversion value). According to the AD value, the pressure value in each air bag 2 is calculated by using the known pressure conversion formula.

[0047] According to the accurate and real-time pressure value information of the air bags 2 detected by the air pressure detection module, the pressure value distribution position and fluctuation change of the user on the seat can be calculated, and through the pressure distribution position information and pressure fluctuation change information and in combination with the angle information of the car massage seat 1, it can be determined whether the user's posture is sitting or lying, or other objects are placed on the seat. Specifically:

[0048] When the angle between the seat cushion 11 and the backrest 12 is less than or equal to θ, and the average pressure value of the lower air bags 2 is higher than the set threshold value ∆data1 in at least N1 groups of air bag groups, it is judged that the current posture of the human body is a sitting posture; when the angle between the seat cushion 11 and the backrest 12 is greater than θ, and the average pressure value of the lower air bags 2 is higher than the set threshold value ∆data2 in at least N1 groups of air bag groups, and the average pressure value of the upper air bags 2 is less than the average pressure value of the lower air bags 2, it is judged that the current posture of the human body is a sitting posture;

[0049] When the angle between the seat cushion 11 and the backrest 12 is greater than θ, and the average pressure value of all air bag groups is higher than the set threshold value ∆data3 in at least N2 groups of air bag groups, it is judged that the current posture of the human body is a lying posture;

[0050] When the average pressure value of each air bag group decreases to less than the air pressure value when the air is fully charged and stabilizes for a period of time, it is judged that the current posture of the human body is a seat leaving posture, and the corresponding pressure change diagram of the seat leaving posture is as shown in Figure 6

[0051] Wherein, N1 < N2, ∆data2 >> ∆data3, 0° ≤ θ ≤ 180°. In this embodiment, N1 = 3, N2 = 6, and the specific values of ∆data2 and ∆data3 are set according to actual conditions.

[0052] Step S2, when the human body is in a sitting or lying posture, the user can press any air bag 2 in the above-mentioned air bag group to issue an interactive instruction, according to the position of the pressed air bag 2 and the change of the pressure value, the specific interactive instruction issued by the human body is judged, and the car massage seat 1 or other electronic components in the car are controlled to respond correspondingly according to the interactive instruction.

[0053] The present application obtains pressure fluctuation change information in the change of the pressure information of each group of air bags 2, and the main control board records and classifies the interactive instructions of the user according to the fluctuation information such as the amplitude of the pressure fluctuation, the number of fluctuations, and the time of the pressure fluctuation. The interactive instructions in this embodiment include single-hand pressing, double-hand pressing, short pressing, and long pressing, short pressing includes one-time pressing, twice pressing, and three-time pressing, and the corresponding pressure change diagrams of each interactive instruction are as shown in Figures 7 to 12 The horizontal axis in the figure is the time sequence, and the vertical axis is the pressure value. The pressure curve in each figure is obtained from the change of the pressure value of the air bag. The horizontal section with a lower amplitude in the pressure curve represents the pressure value when the person leaves the seat, and the horizontal section with a higher amplitude in the figure represents the pressure value after the person sits on the car massage seat. The wave crest appears in the horizontal section with a higher amplitude.

[0054] As Figure 7 For the pressure curve of each air bag group, if a wave crest appears in the high pressure value part of a certain pressure curve, it is judged as single-hand pressing; as Figure 8 ​As shown, if the change trend and change amplitude of two pressure curves are the same, it is determined as double-hand pressing. In actual determination, a certain time error and amplitude error are allowed. For example, Figure 9 As shown, if a wave crest appears in a high-amplitude horizontal section of a pressure curve, it is determined as one pressing; for example, Figure 10 As shown, if two wave crests appear continuously in a pressure curve, it is determined as two pressings; for example, Figure 11 As shown, if three wave crests appear continuously in a pressure curve, it is determined as three pressings; for example, Figure 12 As shown, if a high-pressure section with a duration of t2=3s appears in a pressure curve, it is determined as long pressing. The short pressing and long pressing instructions can be issued by single-hand pressing or double-hand pressing.

[0055] In order to distinguish whether the pressure change is caused by an interactive instruction (short pressing or long pressing) or caused by jolting or human riding, a false touch prevention process is set. Specifically, when the pressure change amount of a single group of air bags 2 is large and the pressures of other air bags 2 are in the change amount range caused by normal riding or lying, or when the pressure change trends of multiple groups of air bags 2 are consistent and only the pressure of a single group of air bags 2 is significantly different from the other air bags 2, it is determined that an interactive instruction is issued. Otherwise, it is considered that the pressure change is caused by vehicle jolting or other object collision, and it is not determined as an interactive instruction. For short pressing, one pressing, two pressings, and three pressings all have corresponding total time consumption, and the width of a single wave crest should be greater than a set first threshold time1 and less than a second threshold time2. Otherwise, it is determined as invalid pressing. For long pressing, if the duration of the high-pressure section reaches a set third threshold time3, it is determined as long pressing. Otherwise, it is determined as invalid pressing. For example, when the air bag 2 is pressed and the timing starts, after 1.5s, it is determined as long pressing. If the air bag 2 is released before the timing reaches 1.5s, the timing is cleared, and this long pressing is considered invalid, so as to avoid determining the pressure caused by normal human riding as a long pressing instruction. The specific values of time1, time2, and time3 are set according to actual conditions.

[0056] As shown, in this embodiment, the seat actions corresponding to each interactive instruction are: Figure 2

[0057] ​When the human body sits or lies on the seat, the backrest 12 air bag 2 is pressed for a long time, and the control seat backrest 12 is inclined forward or backward. The specific setting is: by pressing the left air bag 2 at the lowermost part of the backrest 12 for a long time, triggering the long press action, at this time the backrest 12 continuously inclines forward until the press is released; the right air bag 2 at the lowermost part of the backrest 12 is pressed for a long time, triggering the long press action, at this time the backrest 12 continuously inclines backward until the press is released; for seats other than the main driver, adjustment can be made at any time, for the main driver position, for safety considerations, this function can only be used during the non-driving process of the car, and the driving state of the car is read through the car interface.

[0058] When the cushion 11 air bag 2 is pressed for a long time, the seat is controlled to move forward or backward, or the car massage seat 1 height is controlled to increase or decrease, or the leg support is controlled to be adjusted up or down. The specific setting is: by pressing the right air bag 2 at the rear end of the upper end surface of the cushion 11 for a long time, triggering the long press action, at this time the seat continuously moves backward until the press is released; the left air bag 2 at the rear end of the upper end surface of the cushion 11 is pressed for a long time, triggering the long press action, at this time the seat continuously moves forward until the press is released; for seats other than the main driver, adjustment can be made at any time, for the main driver position, for safety considerations, this function can only be used during the non-driving process of the car, and the driving state of the car is read through the car interface.

[0059] By pressing the right air bag 2 at the front end of the upper end surface of the cushion 11 for a long time, triggering the long press action, at this time the leg support continuously adjusts up until the press is released; the left air bag 2 at the front end of the upper end surface of the cushion 11 is pressed for a long time, triggering the long press action, at this time the leg support continuously adjusts down until the press is released; for seats other than the main driver, adjustment can be made at any time, for the main driver position, for safety considerations, this function can only be used during the non-driving process of the car, and the driving state of the car is read through the car interface.

[0060] By pressing the right air bag 2 at the front end of the upper end surface of the cushion 11 for a long time, triggering the long press action, at this time the leg support continuously adjusts up until the press is released; the left air bag 2 at the front end of the upper end surface of the cushion 11 is pressed for a long time, triggering the long press action, at this time the leg support continuously adjusts down until the press is released; for seats other than the main driver, adjustment can be made at any time, for the main driver position, for safety considerations, this function can only be used during the non-driving process of the car, and the driving state of the car is read through the car interface.

[0061] The ventilation function is turned on or off by pressing twice. Specifically, the ventilation function is divided into two positions: the backrest 12 and the seat cushion 11. To turn on the ventilation function of the backrest 12, either airbag 2 of the backrest 12 is pressed twice; to turn it off, it is pressed twice again. The same operation is performed to turn on the ventilation function of the seat cushion 11. The specific implementation of the ventilation function is existing technology.

[0062] Pressing the airbag 2 of the backrest 12 or the airbag 2 of the seat cushion 11 three times controls the opening or closing of the heating function of the backrest 12 or the airbag. The specific implementation of the heating function is existing technology.

[0063] Pressing the left or right airbag 2 at the front of the upper end of the seat cushion 11 once activates the massage function; pressing it again deactivates it. The specific implementation of the massage function is based on existing technology.

[0064] If the seat position memory function is enabled, when someone is detected sitting down, the seat height and fore-aft position will be automatically adjusted to a reasonable position based on the pressure value; when someone is detected leaving the seat, the seat height and fore-aft position will be automatically adjusted back to the initial position for easy getting on and off the next time.

[0065] Pressing actions trigger the activation and deactivation of related functions. Some press responses are easily perceived by the user, such as a long press triggering adjustments to the seat back angle, fore-aft position, seat height, and leg rest. Other press responses are less noticeable, meaning the user may not easily know if the button operation was successful, such as a short press turning on / off seat ventilation and seat heating. Therefore, appropriate feedback is needed for each operation. This invention uses the rapid inflation and deflation of the press-activated airbag 2 to notify the user that the button operation was successful.

[0066] When the massage function is in progress, the airbag 2 will regularly inflate and deflate to achieve the massage action. At this time, the pressure detection of the massage airbag 2 is turned off, while the pressure detection of the left and right armrest airbags 2 of the car massage seat 1 is turned on. Pressing the armrest airbag 2 twice controls the massage function to be turned off. After the massage function is turned off, the pressure detection of the massage airbag 2 is turned on.

[0067] To make airbag 2 fit the human body better, such as Figure 13 As shown, multiple support adjustment mechanisms 14 are provided on the seat frame 13, and airbags 2 are mounted on the support adjustment mechanisms 14. The pressure value of each airbag 2 is detected to determine whether the back support and leg support are conforming to the human body. When the conformity is not high, some airbags 2 have high pressure, while related airbags 2 have low pressure (related airbags 2, such as upper back and lower back airbags 2). By adjusting the extension and retraction of the support adjustment mechanisms 14, the massage structure of the airbags 2 is propelled to conform to the human body, making the pressure of related airbags 2 more consistent. The support adjustment mechanism 14 is existing technology.

[0068] The support adjustment mechanism 14 has three, two of which are on the backrest 12, one of which is located on the upper backrest 12 and the lower backrest 12, and one of which is located on the seat cushion 11, which is located at the leg support position.
