[0019] In the related art, aromatherapy devices used in automobiles are usually turned on based on manual adjustment so that the aromatherapy devices continue to emit fragrance. However, manual adjustment may cause the driver to be distracted during operation, which poses certain safety hazards. In addition, aromatherapy devices usually spray fragrance in a fixed or single manner. Passengers in the car have different requirements for fragrance, so some passengers are suitable for the current fragrance, while some passengers are not, which affects the comfort of the driver and passengers.

[0020] In order to solve the above problems, the embodiments of the present application provide an aromatherapy device and an aromatherapy device control method.

[0021] In the method, by detecting that the aromatherapy device in the car has been turned on, the seating situation of the occupants in the car is determined, so that the opening and closing state of the aromatherapy device can be accurately understood, and the seating situation of the occupants in the car can be automatically determined when the aromatherapy device is turned on; according to the seating situation of the occupants in the car, the aromatherapy device is controlled to diffuse fragrance, and the aromatherapy device can be adjusted according to the seating situation of the occupants, which not only reduces the operating burden of the driver, but also can improve driving safety to a certain extent, avoid distraction due to manual adjustment of the aromatherapy device, and improve the riding experience.

[0022] The aromatherapy device control method provided in the embodiment of the present application can be applied to an aromatherapy device. In this case, the aromatherapy device is the execution subject of the aromatherapy device control method provided in the embodiment of the present application. The embodiment of the present application does not impose any restrictions on the specific type of the aromatherapy device.

[0023] For example, the aroma device may include a control device and a diffusion regulating device, and the control device is connected to the diffusion regulating device in communication. The diffusion regulating device may include a volatilizer and a fragrance storage; the volatilizer and the fragrance storage are both connected to the control device in communication; wherein the volatilization mode of the volatilizer may be heating volatilization and ultrasonic atomization volatilization. Heating volatilization is to heat the fragrance by a heating element so that the fragrance reaches the volatilization temperature and then emits it in the form of steam; ultrasonic atomization volatilization is to use the high-frequency vibration of ultrasound to atomize the liquid fragrance into tiny particles and then diffuse it into the air. The fragrance storage is a component for storing fragrances. The material of the container has good sealing properties to prevent the fragrance from leaking and volatilizing. The material of the container can be glass or high-quality plastic material, and it can be divided into multiple spaces according to the characteristics of different fragrances to store multiple fragrances. There may be multiple sensors in the car, such as sound sensors, position sensors, angle sensors or environmental sensors, etc. Each sensor is connected to the electronic control unit (ECU) of the car by wire, and the control device of the aroma device may be wirelessly connected to the electronic control unit (ECU) of the car.

[0024] In order to better understand the aromatherapy device control method provided in the embodiment of the present application, the specific implementation process of the aromatherapy device control method provided in the embodiment of the present application is exemplarily introduced below.

[0025] Figure 1 A schematic flow chart of a method for controlling an aromatherapy device provided in an embodiment of the present application is shown. The method for controlling an aromatherapy device includes: S100, when it is detected that the aromatherapy device in the car is turned on, determining the seating situation of the occupants in the car; wherein the seating situation of the occupants in the car is used to indicate whether there are occupants in the main driving seat, the co-pilot seat and the rear seating seat in the car.

[0026] It can be understood that the aromatherapy device can be controlled by the central control system in the car or the application on the mobile phone, so there will be a corresponding start signal. The signal monitoring mechanism can be set in the vehicle's central control system software or the background code of the mobile phone application. When the user clicks the start button, a specific start instruction will be sent to the aromatherapy device. This instruction will be transmitted in the system's communication protocol stack. By monitoring whether this instruction is successfully received, it can be detected whether the aromatherapy device is turned on. For example, in the Bluetooth communication protocol between the mobile phone application and the aromatherapy device, the start instruction can be a specific byte sequence. When the mobile phone application sends this sequence and receives a confirmation feedback signal from the aromatherapy device, it can be determined that the aromatherapy device is turned on. The determination of the seating situation of the people in the car can be determined by infrared sensors or image recognition; wherein, the image recognition determination can be determined by taking pictures with a camera and then using an image recognition method to identify the image to determine the seating situation of the people in the car.

[0027] In a possible implementation, S100, when it is detected that the aromatherapy device in the car is turned on, determining the riding status of the person in the car includes: S110, after detecting that the aromatherapy device in the car has been turned on, obtain the first seating position, the second seating position and the third seating position in the car; wherein the first seating position is the main driving position of the car, the second seating position is the co-pilot position of the car, and the third seating position is the rear seat of the car.

[0028] Exemplarily, obtaining the first sitting position, the second sitting position, and the third sitting position in the car may be obtained by images taken by a camera.

[0029] S120, performing occupant detection on the first seating position, the second seating position and the third seating position respectively to determine the seating situation of the occupants in the car; wherein the seating situation of the occupants in the car is used to indicate whether there is a main driver in the first seating position, whether there is a co-driver in the second seating position, and whether there are rear seat passengers in the third seating position.

[0030] Exemplarily, personnel detection can be performed on the first sitting position, the second sitting position and the third sitting position by an image recognition method; wherein, the image recognition method can be used to continuously capture images of the interior of the vehicle through a camera, and recognize the outline of the human body in the image based on the image, and then determine whether there are rear-seat passengers in the first sitting position, the second sitting position and the third sitting position based on the relative position relationship between the human body and the seat (for example, the human body is located within the driver's seat range, the human body is in the aisle between the co-pilot seat and the rear seats, etc.) and the shape and position of the seat; it can also be determined by a seat pressure sensor and a seat belt buckle recognition and seat mapping method; wherein, the determination by a seat pressure sensor and a seat belt buckle recognition and seat mapping method can be that the seat pressure sensor senses pressure, and a contact sensor is installed on the car seat belt buckle, and a signal is generated when the seat belt is inserted into the buckle, and by mapping the signal of the seat belt buckle with the corresponding seat position, it can be determined whether there are rear-seat passengers in the first sitting position, the second sitting position and the third sitting position.

[0031] S200, controlling the aroma device to diffuse aroma according to the seating situation of the passengers in the car.

[0032] It can be understood that the aroma diffuser is controlled to diffuse the fragrance according to whether there are passengers in the main driving seat, the co-pilot seat and the rear seat in the car.

[0033] With this setting, the aromatherapy device can be adjusted according to the riding conditions of the occupants, which not only reduces the operating burden of the driver, but also improves driving safety to a certain extent, avoids distraction due to manual adjustment of the aromatherapy device, and improves the riding experience.

[0034] In one possible implementation, see Figure 2 S200 controls the aroma diffuser to diffuse the aroma according to the passenger situation in the car, including: S210, when the seating situation of the people in the car indicates that there is a main driver in the first seating position, retrieve the car owner data of the car; wherein the car owner data is used to indicate the behavior habits of the car owner.

[0035] For example, when the seating situation of the people in the car indicates that there is a main driver in the first seating position, the owner data of the car can be retrieved from the vehicle central control system; wherein the vehicle central control system has a local user profile; the user profile is created by the owner when setting up the vehicle for the first time after purchasing the car, and the owner data can be searched, accessed and retrieved in the user profile of the vehicle central console system. The behavior habits of the car owner include driving habits (such as seat position adjustment habits, steering wheel holding habits and rearview mirror adjustment angle habits, etc.) and multimedia preferences (such as radio stations, music playlists), the seat position adjustment habits can be the seat position adjustment distance value, the steering wheel holding habits can be the steering wheel holding position and the rearview mirror adjustment angle habits can be the rearview mirror adjustment angle value.

[0036] S220, detecting the personnel data of the current main driver; wherein the personnel data is used to indicate the behavior habits of the current main driver.

[0037] It can be understood that the personnel data of the current main driver can be detected by using sensors; for example, when using sensors for detection, since most car seats are electrically controlled, linear displacement sensors can be installed in the seat rails (front and rear adjustment) and lifting mechanisms (up and down adjustment). The linear displacement sensors can accurately measure the movement distance of the seat in all directions; the existing rearview mirror adjustment is mostly electrically adjusted, and an angle encoder can be installed in the regulator of the rearview mirror. The angle encoder can record the angle changes of the rearview mirror in the horizontal and vertical directions in real time; a pressure sensor array can also be installed on the surface or inside of the steering wheel. The sensor can be a pressure sensor based on capacitive, resistive or piezoelectric principles. When the driver holds the steering wheel, the pressure sensors at different positions will detect the change in pressure. For example, multiple pressure sensors are installed at the 3 o'clock and 9 o'clock positions of the steering wheel. When the driver holds these two positions with both hands, the pressure sensor will convert the pressure signal into an electrical signal, and the vehicle control system can analyze the distribution of the holding pressure based on these signals.

[0038] S230, obtaining first similarity data based on the personnel data and the vehicle owner data; wherein the first similarity data is used to indicate the similarity between the behavior habits indicated by the personnel data and the behavior habits indicated by the vehicle owner data.

[0039] Exemplarily, the behavioral habits indicated by the personnel data are compared with the behavioral habits indicated by the vehicle owner data to obtain the overlap between the behavioral habits indicated by the personnel data and the behavioral habits indicated by the vehicle owner data, and the overlap after comparison is determined as the first similar data.

[0040] In one possible implementation, see Figure 3 , S230, obtaining first similar data based on the personnel data and the vehicle owner data, including: S231, based on the comparison of the distance from the car seat to the accelerator pedal after the current main driver adjusted the car seat as indicated by the personnel data with the distance from the car seat to the accelerator pedal of the car owner as indicated by the car owner data, and the comparison of the adjustment amplitude of the rearview mirror by the current main driver as indicated by the personnel data with the adjustment amplitude of the rearview mirror by the car owner as indicated by the car owner data, to obtain adjustment data; the adjustment data is used to indicate the similarity obtained after comparing the distances from the car seat to the accelerator pedal and the similarity obtained after comparing the adjustment amplitudes of the rearview mirror.

[0041] It can be understood that the distance from the car owner's car seat to the accelerator pedal is obtained from the retrieved car owner data, and after the current main driver adjusts the car seat, the distance from the car seat to the accelerator pedal is obtained through real-time detection, and the distance from the current main driver's car seat to the accelerator pedal is compared with the distance from the car owner's car seat to the accelerator pedal to obtain a first comparison situation, wherein the comparison method can be to subtract the distance from the car owner's car seat to the accelerator pedal from the distance from the current main driver's car seat to the accelerator pedal to obtain a positive difference, 0 difference or negative difference, and perform similarity matching on the positive difference, 0 difference or negative difference to obtain a first matching result, and determine the first matching result as the first comparison situation; if the difference is 0 difference, it proves that the current driver has not adjusted the distance from the car seat to the accelerator pedal, and if the difference is a positive difference or a negative difference, it proves that the current driver has adjusted the distance from the car seat to the accelerator pedal. The positive difference, 0 difference or negative difference is matched for similarity. A 0 difference means a similarity of 100%; the larger the positive difference, the smaller the similarity. For example, in the first case, the distance from the car owner's car seat to the accelerator pedal is 10 cm. After the current main driver adjusts the car seat, the distance from the car seat to the accelerator pedal is 15 cm, so a positive difference of 5 is obtained; in the second case, the distance from the car owner's car seat to the accelerator pedal is 10 cm. After the current main driver adjusts the car seat, the distance from the car seat to the accelerator pedal is 12 cm, so a positive difference of 2 is obtained; comparing the first case with the second case, 2 is less than 5, so the similarity of the second case is greater than that of the first case; the similarity calculation formula is ; ; is the difference, It is the distance from the car seat to the accelerator pedal after the current driver adjusts the car seat. is the distance from the car owner's car seat to the accelerator pedal, S is the similarity, K is a constant, and its value is 0.1; that is, when the positive difference is 5, the similarity is , when the positive difference is 2, , that is, the similarity of the second case is greater than that of the first case.

[0042] The smaller the negative difference, the smaller the similarity. For example, in the first case, the distance from the car owner's car seat to the accelerator pedal is 10cm. After the current main driver adjusts the car seat, the distance from the car seat to the accelerator pedal is 8cm, so the negative difference is -2. In the second case, the distance from the car owner's car seat to the accelerator pedal is 10cm. After the current main driver adjusts the car seat, the distance from the car seat to the accelerator pedal is 5cm. Then, the negative difference is -5. Comparing the first and second cases, -2 is greater than -5, so the similarity of the first case is greater than the similarity of the second case. The similarity calculation formula is: ; ; is the difference, It is the distance from the car seat to the accelerator pedal after the current driver adjusts the car seat. is the distance from the car owner's car seat to the accelerator pedal, S is the similarity, K is a constant, and its value is 0.1; that is, when the negative difference is -5, the similarity is ; When the negative difference is -2, , that is, the similarity of the first case is greater than that of the second case.

[0043] The adjustment amplitude of the rearview mirror by the car owner is obtained from the retrieved car owner data, and the adjustment amplitude of the rearview mirror by the current main driver is compared with the adjustment amplitude of the rearview mirror by the car owner to obtain the second comparison situation; wherein, the adjustment amplitude of the rearview mirror by the current main driver is subtracted from the adjustment amplitude of the rearview mirror by the car owner to obtain a positive amplitude, a zero amplitude or a negative amplitude, and the positive amplitude, the zero amplitude or the negative amplitude are matched for similarity to obtain a second matching result, and the second matching result is determined as the second comparison situation; and then the first comparison situation and the second comparison situation are determined as the adjustment data; if the amplitude of the rearview mirror after comparison is zero amplitude, it proves that the current driver has not adjusted the rearview mirror, and if the amplitude after comparison is positive amplitude or negative amplitude, it proves that the current driver has adjusted the rearview mirror. The positive amplitude, the zero amplitude or the negative amplitude are matched for similarity. If the adjustment amplitude of the rearview mirror by the current main driver minus the adjustment amplitude of the rearview mirror by the car owner is zero amplitude, then the zero amplitude corresponds to a similarity of 100%, that is, the result of the second comparison situation is a similarity of 100%; The larger the positive amplitude, the smaller the similarity. For example, in the first case, the adjustment amplitude of the rearview mirror by the car owner is 10 degrees, and the current main driver car owner adjusts the rearview mirror by 15 degrees, so the positive amplitude is 5 degrees; in the second case, the adjustment amplitude of the rearview mirror by the car owner is 10 degrees, and the current main driver car owner adjusts the rearview mirror by 11 degrees, so the positive amplitude is 1 degree; then, comparing the first case with the second case, 1 is less than 5, so the similarity of the second case is greater than that of the first case. The similarity calculation formula is ; ; is the difference; k is a constant, and its value is 0.1; is the current adjustment range of the rearview mirror by the main driver, is the adjustment amplitude of the rearview mirror by the car owner. The specific calculation method is the same as the above method and will not be repeated here. The smaller the negative amplitude, the smaller the similarity. For example, in the first case, the adjustment amplitude of the rearview mirror by the car owner is 10 degrees, and the current main driver car owner adjusts the rearview mirror by 7 degrees, so the negative amplitude is -3 degrees; in the second case, the adjustment amplitude of the rearview mirror by the car owner is 10 degrees, and the current main driver car owner adjusts the rearview mirror by 5 degrees, so the negative amplitude is -5 degrees; then, comparing the first case with the second case, -3 is greater than -5, so the similarity of the first case is greater than the similarity of the second case. The similarity calculation formula is ; k is a constant, and its value is 0.1; ; is the difference, is the current adjustment range of the rearview mirror by the main driver, It is the adjustment range of the rearview mirror by the car owner. The specific calculation method is the same as the above calculation method and will not be repeated here. In addition, if the difference is 0 difference and the adjustment range of the rearview mirror is positive or negative, it is necessary to detect the adjustment degree of the positive or negative amplitude. If the adjustment degree of the positive or negative amplitude is large (it can be more than 40% or more of the adjustment range of the rearview mirror by the car owner), it indicates that it is not the car owner; if the difference is a positive difference or a negative difference, and the adjustment range of the rearview mirror is 0 amplitude, it is the same as the above method and will not be repeated here.

[0044] S232, based on the difference comparison between the current main driver's gripping of the car steering wheel reflected by the personnel data and the car owner's gripping of the car steering wheel indicated by the car owner data, the gripping data is obtained; the gripping data is used to indicate the similarity obtained after comparing the gripping of the car steering wheel.

[0045] It can be understood that the grip data is obtained by comparing the difference between the grip force diagram of the current main driver on the car steering wheel reflected by the personnel data and the grip force diagram of the car owner on the car steering wheel indicated by the car owner data; wherein, the grip force diagram can be obtained by measuring with a strain gauge, for example, a strain gauge is pasted on the surface of the steering wheel, and when the steering wheel is subjected to the grip force, the strain gauge will undergo a resistance change, which is converted into a stress value and a strain value through the resistance change of the strain gauge, thereby obtaining the grip force diagram. The grip force diagram of the current main driver on the car steering wheel can also be obtained by detecting with a pressure sensor, and the pressure sensor can be installed inside the outer ring wrapping layer of the steering wheel; in addition, whether the grip force diagram is obtained by using a strain gauge or a pressure sensor, multiple locations are required, and there can be 4 grip force diagrams on the steering wheel that need to be compared. The 4 grip force diagrams that need to be compared can be to divide the steering wheel into upper, lower, left and right parts, and the steering wheel is divided when the wheel is in the straightening state, wherein the 4 locations The grip force diagrams that need to be compared may each have a key comparison point, such as the 12 o'clock position (upper part), the 3 o'clock position (right part), the 6 o'clock position (lower part), and the 9 o'clock position (left part) as key comparison points. In addition, the 4 grip force diagrams that need to be compared may each have a common comparison point, such as the 11:30 position (upper part) and the 12:30 position (upper part), the 2:30 position (right part) and the 3:30 position (right part), the 5:30 position (lower part) and the 6:30 position. 8:30 position (left) and 9:30 position (left); in the comparison, the weight of the key comparison point is 60%, and the weight of the common point is 40%; for example, if the key comparison points in the upper part are all overlapped, then the calculation of the key comparison points in the upper part is 100×60%=60, that is, the similarity of the key comparison points is 60%, and the common points are half overlapped, then the calculation of the common comparison points is 50×40%=20, that is, the similarity of the common comparison points is 20%, and the similarity of the common comparison points is added to the similarity of the key comparison points. The similarity obtained is 20% + 60% = 80%, so the total similarity of the upper part is 80%, and the total similarity of the lower part, the total similarity of the left part and the total similarity of the right part are calculated in the same way, which will not be repeated here. After the total similarity of the upper part, the total similarity of the lower part, the total similarity of the left part and the total similarity of the right part are calculated, the total similarity of the upper part, the total similarity of the lower part, the total similarity of the left part and the total similarity of the right part are calculated according to the formula Xs = (A × 0.25) + (B × 0.25) + (C × 0.25) + (D × 0.25) Calculate the overall similarity (the overall similarity is the similarity indicated by the grip data, that is, the upper, lower, left and right parts are calculated with a weight of 25% respectively, and then the calculated weights are added together to obtain the grip data); Xs is the overall similarity, A is the upper part, B is the lower part, C is the left part, and D is the right part; for example, the total similarity of the upper part is 80%, the total similarity of the lower part is 90%, the total similarity of the left part is 79%, and the total similarity of the right part is 85%, (80%×0.25)+(90%×0.25)+(79%×0.25)+(85%×0.25))=83.5 , that is, Xs=83.5%, that is, the overall similarity is 83.5%, that is, the similarity indicated by the grip data is 83.5%; the grip force diagram of the car owner on the car steering wheel can be obtained from the car owner data; by checking whether the grip force diagram of the current main driver on the car steering wheel coincides with the grip force diagram of the car owner on the car steering wheel indicated by the car owner data, if the grip force diagram of the current main driver on the car steering wheel coincides with the grip force diagram of the car owner on the car steering wheel indicated by the car owner data, the similarity is 100%, and the similarity of 100% is determined as the grip data. .

[0046] S233: Obtain first similarity data according to the adjustment data and the holding data.

[0047] Exemplarily, the first similarity data is obtained by weighting the adjustment data and the gripping data; wherein the weight of the adjustment data is 60%, and the weight of the gripping data is 40%, the similarity indicated by the adjustment data is multiplied by 60% to obtain the first weighted similarity, and the similarity indicated by the gripping data is multiplied by 40% to obtain the second weighted similarity, and then the first weighted similarity and the second weighted similarity are added together to obtain the total weighted similarity, which is determined as the first similarity data. For example, the similarity indicated by the adjustment data is 90, and the similarity indicated by the gripping data is 95, and (90×60%)+(95×40%)=92, then the similarity indicated by the first similarity data is 92.

[0048] This setting not only allows the aromatherapy device to quickly confirm whether the current main driver is the car owner, so as to improve privacy protection and driving safety, but also provides different aroma adjustment methods and aromas for different main drivers, further enhancing the driving experience. It not only enhances the user's sense of belonging to the vehicle, but also effectively improves the overall driving comfort and safety.

[0049] S240, when the seating situation of the occupants in the car indicates that there is no front passenger in the second seating position and no rear passenger in the third seating position, and the similarity indicated by the first similarity data is within the value range of the first threshold, the aroma diffuser is controlled to diffuse the aroma according to the owner's preset data; wherein the owner's preset data is used to indicate the type of aroma diffused by the aroma diffuser and the aroma adjustment speed preset by the owner, and the value range of the first threshold is 80%-100%.

[0050] It can be understood that the car owner's preset data is used to indicate the type of fragrance diffused by the aroma diffuser and the fragrance adjustment speed preset by the car owner. The type of fragrance diffused by the aroma diffuser preset by the car owner can be understood as the fragrance set by the car owner according to his or her own preferences (for example, a refreshing fragrance (mint fragrance or lemon fragrance), a relaxing fragrance (lavender fragrance or sandalwood fragrance) or a fragrance customized by the car owner; wherein different fragrances are diffused according to different passengers, for example, the aroma diffuser may include a plurality of independent fragrance source storage chambers and a control structure (the control structure may be a microcontroller) that controls each independent fragrance source storage chamber to emit fragrance; each independent fragrance source storage chamber is equipped with a diffusion switch, and each diffusion switch is communicated with the control structure, and the control structure is configured to control different passengers when they are in the car. The structure receives a control instruction sent by a control device inside the aroma device. After receiving the control instruction, the control structure controls the corresponding diffusion switch to open so that the fragrance can diffuse. The fragrance adjustment speed refers to the speed at which the aroma device changes the fragrance concentration in the car, for example, it can be in cubic meters per hour (m³ / h). The speed at which the aroma device changes the fragrance concentration in the car is different in different time periods. The value range of the first threshold is 80%-100%, greater than 80% or equal to 100%, such as 80.1%, 80.5%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or 100%, etc., but not limited to this.

[0051] Exemplarily, when the seating situation of people in the car indicates that there is no front passenger in the second seating position and no rear passenger in the third seating position, and the similarity indicated by the first similarity data is within the range of 80%-100%, the aroma device is controlled according to the owner's preset data to diffuse the aroma according to the preset aroma type and adjust the aroma at the preset aroma adjustment speed.

[0052] In a possible implementation, the method further includes: S240A, when the seating situation of the people in the car indicates that there is no front passenger in the second seating position and no rear passenger in the third seating position, and the similarity indicated by the first similarity data is not within the value range of the first threshold, generate inquiry data; wherein the inquiry data is used to indicate the inquiry of the current main driver to select the fragrance type and diffusion speed of the aromatherapy device.

[0053] It can be understood that the inquiry data indicates that asking the current main driver about the type of fragrance and diffusion speed of the aromatherapy device selected can be done by using a car computer assistant, or by using an amplifier on the car to transmit the inquiry content as an inquiry voice; the car computer assistant can be, for example, Xiao Ai on a Xiaomi car, Siri in Car-play, etc., but is not limited to this.

[0054] Exemplarily, when the seating situation of the occupants in the car indicates that there is no front passenger in the second seating position and no rear passenger in the third seating position, and the similarity indicated by the first similarity data is less than 80% (i.e., any value between 0 and 79.99%), the current main driver will be asked to select the fragrance type and diffusion speed of the aromatherapy device.

[0055] S240B, acquiring voice data, and controlling the aroma device to diffuse fragrance based on the voice data.

[0056] It can be understood that the voice data is used to indicate what is said to the current main driver (i.e., the aroma type and aroma diffusion speed of the aroma diffuser); wherein, the voice of the current main driver can be recognized by the car assistant, and the recognized instructions are sent to the aroma diffuser, which processes it to diffuse the corresponding aroma type and aroma diffusion speed.

[0057] In one possible implementation, see Figure 4 S200 controls the aroma diffuser to diffuse the aroma according to the passenger situation in the car, including: S201, when the seating situation of the occupants of the automobile indicates that there is a main driver in the first seating position, a front passenger in the second seating position, and no rear seat occupant in the third seating position, and the similarity indicated by the first similarity data is within the value range of the first threshold, retrieve the front passenger position data of the automobile; wherein the front passenger position data is used to indicate the behavioral habits of the spouse of the automobile owner.

[0058] Exemplarily, the passenger seat position data of the car can be retrieved from the vehicle central control system. The retrieval step is similar to the operation method of step S210, that is, the local user profile in the vehicle central control system; the user profile is when the owner sets up the vehicle for the first time after purchasing the car. In addition to creating his own user profile, he also sets the situation of the passenger seat and the back row. The passenger seat position data can be searched, accessed and retrieved in the user profile of the vehicle central console system. The behavioral habits of the spouse of the car owner can be riding habits (such as the angle of the seat back, the opening angle of the sun visor makeup mirror and the distance after the seat is adjusted), etc.

[0059] S202, detecting the motion data of the co-pilot currently in the second seating position; wherein the motion data is used to indicate the current behavioral habits of the co-pilot.

[0060] Exemplarily, the motion data of the co-pilot in the current second seating position is detected by a sensor; among them, most car seats are electrically controlled, that is, linear displacement sensors can be installed in the seat guide rails (forward and backward adjustment) and lifting mechanisms (up and down adjustment). The linear displacement sensors can accurately measure the movement distance of the seat in all directions, and the angle sensors on the car seats can be used to obtain the adjustment angle of the car seat backrest; the sun visor makeup mirror can be detected by an angle encoder when it is opened, and the opening angle of the sun visor makeup mirror can be identified, and the angle encoder can record the opening angle of the sun visor makeup mirror in real time; both the angle encoder and the linear displacement sensor can be connected to the vehicle system.

[0061] S203, obtaining second similarity data based on the action data and the passenger seat position data; wherein the second similarity data is used to indicate the similarity between the behavior habit indicated by the passenger seat position data and the behavior habit indicated by the action data.

[0062] Exemplarily, the behavioral habits indicated by the action data are compared with the behavioral habits indicated by the vehicle owner data to obtain the overlap between the behavioral habits indicated by the action data and the behavioral habits indicated by the vehicle owner data, and the overlap after comparison is determined as the second similar data.

[0063] In one possible implementation, see Figure 5 , S203, obtaining second similar data based on the action data and the co-pilot position data, including: S2031, obtaining first angle data by comparing the angle value of the car backrest adjusted by the current co-pilot indicated by the action data with the angle value of the car backrest of the car owner's spouse indicated by the co-pilot position data; wherein the first angle data is used to indicate the similarity obtained after comparing the angle values ​​of the car backrest.

[0064] It can be understood that the angle value of the car backrest adjusted by the current co-pilot indicated by the action data is subtracted from the angle value of the car backrest of the car owner's spouse indicated by the co-pilot position data to obtain a positive angle value, a 0 angle value or a negative angle value, and the positive angle value, the 0 angle value or the negative angle value are matched with each other to obtain an angle similarity value, and the angle similarity value is determined as the first angle data. The positive angle value, 0 angle value or negative angle value are matched with similarity. If the value obtained by subtracting the angle value of the car backrest of the spouse of the car owner from the angle value of the car backrest adjusted by the current co-pilot is 0, then the 0 angle value corresponds to a similarity of 100, that is, the similarity indicated by the first angle data is 100%; the larger the positive angle value, the smaller the similarity. For example, in the first case, the angle value of the car backrest of the spouse of the car owner is 10, and the angle value of the car backrest adjusted by the current co-pilot is 15, then the positive angle value is 5; in the second case, the angle value of the car backrest of the spouse of the car owner is 10, and the angle value of the car backrest adjusted by the current co-pilot is 11, then the positive angle value is 1; then, comparing the first case with the second case, 1 is less than 5, so the similarity of the second case is greater than that of the first case. The similarity calculation formula is: ; ; is the difference; k is a constant, and its value is 0.1, is the angle value after the co-pilot adjusts the car backrest. is the angle value of the car backrest of the spouse of the car owner. The specific calculation method is the same as the above calculation method, which will not be repeated here. The smaller the negative angle value, the smaller the similarity. For example, in the first case, the angle value of the car backrest of the spouse of the car owner is 10, and the angle value after the current co-pilot adjusts the car backrest is 7, so the negative angle value is -3; in the second case, the angle value of the car backrest of the spouse of the car owner is 10, and the angle value after the current co-pilot adjusts the car backrest is 5, so the negative angle value is -5; then, comparing the first case with the second case, -3 is greater than -5, so the similarity of the first case is greater than the similarity of the second case. The similarity calculation formula is ; ; is the difference, k is a constant, and its value is 0.1; is the angle value after the co-pilot adjusts the car backrest. It is the angle value of the car backrest of the car owner's spouse. The specific calculation method is the same as the above calculation method and will not be repeated here.

[0065] S2032, comparing the opening angle value of the sun visor makeup mirror of the current co-pilot indicated by the action data with the opening angle value of the sun visor makeup mirror of the car owner's spouse indicated by the co-pilot position data, to obtain second angle data; wherein the second angle data is used to indicate the similarity obtained after comparing the opening angle values ​​of the sun visor makeup mirror.

[0066] Exemplarily, the opening angle value of the sun visor makeup mirror of the current co-pilot indicated by the action data is subtracted from the opening angle value of the sun visor makeup mirror of the spouse of the car owner indicated by the co-pilot position data to obtain a positive opening angle value, a 0 opening angle value, or a negative opening angle value, and the positive opening angle value, the 0 opening angle value, or the negative opening angle value are matched for similarity to obtain an opening angle similarity value, and the opening angle similarity value is determined as the second angle data. The positive opening angle value, the 0 opening angle value, or the negative opening angle value are matched for similarity, and if the value obtained by subtracting the opening angle value of the sun visor makeup mirror of the spouse of the car owner from the opening angle value of the current co-pilot is 0, then the 0 opening angle value corresponds to a similarity of 100, that is, the similarity indicated by the second angle data is 100%.

[0067] The larger the positive opening angle value, the smaller the similarity. For example, in the first case, the opening angle value of the sun visor makeup mirror of the car owner's spouse is 12, and the current opening angle value of the sun visor makeup mirror of the co-pilot is 17, so the positive opening angle value is 5; in the second case, the opening angle value of the sun visor makeup mirror of the car owner's spouse is 12, and the current opening angle value of the sun visor makeup mirror of the co-pilot is 13, so the positive opening angle value is 1; then, comparing the first case with the second case, 1 is less than 5, so the similarity of the second case is greater than that of the first case. The similarity calculation formula is ; ; is the difference; k is a constant and takes the value of 0.1; is the current opening angle of the sun visor vanity mirror of the co-pilot; is the opening angle value of the sun visor makeup mirror of the spouse of the car owner. The specific calculation method is the same as the above calculation method, which will not be repeated here. The smaller the negative opening angle value, the smaller the similarity. For example, in the first case, the opening angle value of the sun visor makeup mirror of the spouse of the car owner is 13, and the current opening angle value of the sun visor makeup mirror of the co-pilot is 10, so the negative opening angle value is -3; the second case is that the opening angle value of the sun visor makeup mirror of the spouse of the car owner is 13, and the current opening angle value of the sun visor makeup mirror of the co-pilot is 8, so the negative opening angle value is -5; then, comparing the first case with the second case, -3 is greater than -5, so the similarity of the first case is greater than the similarity of the second case. The similarity calculation formula is ; ; is the difference, k is a constant, and its value is 0.1; is the current opening angle of the sun visor vanity mirror of the co-pilot; It is the opening angle value of the sun visor vanity mirror of the spouse of the car owner. The specific calculation method is the same as the above calculation method and will not be repeated here.

[0068] S2033, obtaining seat belt data by comparing the length of seat belt usage of the current front passenger indicated by the action data with the length of seat belt usage of the spouse of the car owner indicated by the front passenger position data; wherein the seat belt data is used to indicate the similarity obtained after comparing the lengths of seat belt usage.

[0069] It can be understood that by obtaining the length value of the seat belt used by the spouse of the car owner, by detecting the length value of the seat belt used by the current co-pilot indicated by the action data, the length difference is obtained by subtracting the length value of the seat belt used by the spouse of the car owner from the length value of the seat belt used by the current co-pilot, and the similarity is determined according to the length difference. Among them, the length value of the seat belt used by the current co-pilot indicated by the action data can be detected by a capacitive displacement sensor, and the capacitive displacement sensor can be installed on the housing of the seat belt retractor. The length difference obtained by subtracting the length value of the seat belt used by the spouse of the car owner from the length value of the seat belt used by the current co-pilot includes a 0 difference, a positive length difference and a negative length difference. When the length difference is a 0 difference, it proves that the length value of the seat belt used by the current co-pilot is the same as the length value of the seat belt used by the spouse of the car owner, and the similarity is 100%. If the length difference obtained by subtracting the length value of the seat belt used by the current co-pilot from the length value of the seat belt used by the spouse of the car owner is a positive length difference, according to the similarity calculation formula: ; ; is the difference; k is a constant and takes the value of 0.1; is the current length of the seat belt used by the co-pilot; is the length of the seat belt used by the spouse of the car owner. The specific calculation method is the same as the above calculation method and will not be repeated here. If the length difference between the current length of the seat belt used by the co-pilot and the length of the seat belt used by the spouse of the car owner is a negative length difference, the similarity calculation formula is: ; ; is the difference, k is a constant, and its value is 0.1; is the current length of the seat belt used by the co-pilot. is the length of the seat belt used by the spouse of the car owner; the specific calculation method is the same as the above calculation method, which will not be repeated here. In addition, if the current co-pilot does not open the sun visor makeup mirror and the current co-pilot does not adjust the car backrest, then only the similarity indicated by the seat belt data is the final similarity.

[0070] S2034: Obtain the second similarity data according to the first angle data, the second angle data and the seat belt data.

[0071] Exemplarily, the second similar data is obtained by weight calculation based on the first angle data, the second angle data and the seat belt data; wherein, the step of obtaining the second similar data is substantially similar to step S233, that is, the weight of the first angle data is 20%, the weight of the second angle data is 30%, the weight of the seat belt data is 50%, the similarity indicated by the first angle data is multiplied by 20% to obtain a third weighted similarity, the similarity indicated by the second angle data is multiplied by 30% to obtain a fourth weighted similarity, and the similarity indicated by the seat belt data is multiplied by 50% to obtain a fifth weighted similarity, and the third weighted similarity, the fourth weighted similarity and the fifth weighted similarity are added together to obtain a result weighted similarity, which is determined as the second similar data. For example, the similarity indicated by the first angle data is 85, and the similarity indicated by the second angle data is 90, and (85×20%)+(90×30%)+(90×50%)=89, then the similarity indicated by the first similar data is 89.

[0072] S204, when the similarity indicated by the second similarity data is within the value range of the second threshold, the aroma diffuser is controlled to diffuse the aroma according to the spouse preset data; wherein the spouse preset data is used to indicate the aroma type and aroma adjustment speed of the aroma diffuser preset by the spouse of the car owner, and the second threshold range is 80%-100%.

[0073] It can be understood that the spouse preset data is used to indicate the type of aroma diffused by the aroma diffuser preset by the spouse and the aroma adjustment speed. The type of aroma diffused by the aroma diffuser preset by the spouse can be understood as the aroma set by the car owner according to the needs of the spouse or the spouse of the car owner according to his or her own preferences (for example, a relaxing aroma (lavender aroma, fruity aroma, milk aroma or sandalwood) or an aroma customized by the spouse. The aroma adjustment speed can be adjusted according to different road conditions, distance to home or mood. For example, the closer the distance to home is, the slower the aroma adjustment speed will be. The first threshold range is 80%-100%, that is, greater than 80% is equal to 100%, for example, it can be 80.1%, 80.4%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or 100%, etc., but not limited to this.

[0074] In a possible implementation, the method further includes: When the similarity indicated by the second similarity data is not within the value range of the second threshold, the aroma device is controlled to diffuse the fragrance according to the preset data of the vehicle owner.

[0075] It can be understood that when the seating situation of people in the car indicates that there are no rear passengers in the third seating position, and when the similarity indicated by the second similarity data is less than 80% (i.e., any value between 0 and 79.99%), the aromatherapy device will be controlled to diffuse the fragrance according to the owner's preset data.

[0076] In one possible implementation, see Figure 6 S200 controls the aroma diffuser to diffuse the aroma according to the passenger situation in the car, including: S2001, when the seating situation of the occupants in the car indicates that there is a main driver in the first seating position and there is a rear passenger in the third seating position, obtain the sound feature data of the rear passenger currently sitting in the third seating position; wherein the sound feature data is used to indicate the timbre value, pitch value and speaking speed value of the rear passenger in the third seating position.

[0077] Exemplarily, the sound characteristic data of the rear passenger currently sitting in the third seating position is acquired through a sound collecting device, and the sound collecting device may acquire the sound characteristic data through a sound sensor or a vocal cord analyzer.

[0078] S2002, determining seating data of rear seat passengers in a third seating position based on the sound feature data; wherein the seating data is used to indicate whether the rear seat passengers in the third seating position include children.

[0079] Exemplarily, the seating data of the rear seat passengers in the third seat is determined by analyzing the timbre value, pitch value and speech speed value of the rear seat seats. Among them, multiple frequencies of the timbre are obtained, and the proportion of low frequency and high frequency in the multiple frequencies is compared. If one-third, one-half or two-thirds are high frequencies, it is proved that the rear seat passengers include children; when obtaining multiple fundamental frequencies of the pitch, if one-third, one-half or two-thirds of the values ​​of the multiple fundamental frequencies are 165Hz-450Hz, it is proved that the rear seat passengers include children; obtain multiple sentences, and change the speech speed value used from the beginning to the end of each sentence to obtain a speech speed value change curve. If the speech speed value in each sentence has a significant increase or decrease, the speech speed value is calculated. If the speed of the sentence is slower than normal, or there are multiple obvious speed increases or decreases in a sentence, then it proves that the passengers in the back seat include children; if the speed of the sentence is obviously faster or slower; for example, a sentence has 16 words, if the speed of the first four words is 3, there is a pause of 5 seconds when speaking the 4th to 9th words, and the speech is not continuous, the speed of the sentence suddenly increases to 8 when speaking the 10th to 12th words, and drops to 5 when speaking the 13th to 16th words, then the sentence change curve is normal speed, pause + incoherence, fast speed, and faster than normal speed, which proves that the passengers in the back seat include children.

[0080] S2003, controlling the aroma device to diffuse aroma according to the riding data.

[0081] It can be understood that when the rear passengers in the third seating position indicated by the seating data include children, the aromatherapy device is controlled to diffuse fragrance.

[0082] In one possible implementation, see Figure 7 , S2003, controlling the aroma device to diffuse aroma according to the riding data, including: S20031, when the seating data indicates that there is a child in the third seating position, determining the child's emotional data based on the sound feature data; wherein the emotional data is used to indicate the child's current emotion, and the child's current emotion is good or bad, a good emotion means that the timbre value is less than or equal to a preset timbre value, the pitch value is less than or equal to a preset pitch value, and the speech speed value is less than or equal to a preset speech speed value, and a bad emotion means that the timbre value is greater than the preset timbre value, the pitch value is greater than the preset pitch value, and the speech speed value is greater than the preset speech speed value.

[0083] Exemplarily, when the seating data indicates that there is a child in the third seating position, the child's emotional data is determined based on the timbre value, pitch value and speech speed value; wherein, the timbre value, pitch value and speech speed value emitted by the child in the third seating position are obtained, and the timbre value is detected by spectrum. If the center of mass of the spectrum (the center of gravity of the energy distribution in the sound spectrum) is high, it means that there are more high-frequency components, which proves that the child's emotion is good in the process of timbre value judgment, otherwise it is bad; the obtained pitch value is detected, that is, the fundamental frequency (the basic frequency of sound vibration) in the pitch value is detected. If the fundamental frequency increases, the average fundamental frequency is 30-50Hz higher than that of the calm state, and at the same time, the standard deviation of the pitch value also becomes larger, which proves that the child's emotion is good in the process of pitch value judgment. The obtained speech speed value is tested. If the number of words spoken per second increases by 20%-30% compared with the preset speech speed, and fewer pauses indicate good language coherence, then it proves that the child's emotion is good in the process of pitch value judgment, otherwise it is bad emotion; wherein the speech speed value can be preset, for example, 15 words can be spoken in 10 seconds, 8 words can be spoken in 5 seconds, etc.; bad emotions can include anger, grievance and crying, etc., and when angry, the number of words spoken is small and there are few pauses. When aggrieved, the speech speed is slower than the preset speech speed, and the pitch value and timbre value are small. When crying, the speech has pauses during the intervals, and there are many pauses (for example, many pauses can be one to three normal pauses, while the number of pauses in crying may be greater than 5 times or even more than 10 times), and the number of words is small.

[0084] S20032, identifying the child in the third seating position based on the emotion data to obtain child identity data; wherein the child identity data is used to indicate the child's gender.

[0085] Exemplarily, a first analysis result is obtained by identifying the timbre value of the child in the third seating position, a second analysis result is obtained by identifying the pitch value, and a third analysis result is obtained by identifying the speech rate value. The first analysis result, the second analysis result, and the third analysis result are weighted to obtain a weight determination result, and the weight determination result is determined as the child identity data. Among them, the frequency displayed according to the obtained timbre value of the child is determined as the resonance frequency, and the number of high-frequency components of the peak value of the resonance frequency accounts for one-third or less than one-third of the total resonance frequency, which means that the result reflected by the timbre value is male, that is, male is determined as the first analysis result, otherwise female is determined as the first analysis result; the frequency band composed of multiple low frequencies and multiple high frequencies is called the resonance frequency; according to the multiple fundamental frequency values ​​of the pitch value of the child obtained, the change curve of the pitch value can be described according to the multiple fundamental frequency values. If the multiple fundamental frequency values ​​are between 150 Hz and 280 Hz, and the average fundamental frequency value is below 200, and the change curve of the pitch value is gentle, then the result reflected by the pitch value is male, that is, male is determined as the second analysis result; if the multiple fundamental frequency values ​​are between 285 Hz and 350 Hz, the fundamental frequency of the child is between 200 Hz and 350 Hz. Hz, and the average fundamental frequency value is above 300, the change curve of the pitch value changes greatly, and female is determined as the second analysis result; the speech rate value analysis can be analyzed by the speech rate analysis method, and the speech rate value is calculated by analyzing the syllables and pause duration in the signal. The syllable counting method can be used to analyze the number of syllables in the unit interval audio. The number of syllables in the unit interval of female will be more, and the number of syllables in the unit interval of male will be less, so as to determine the third analysis result; the timbre value, pitch value and speech rate value are determined with a weight ratio of 45%, 35% and 20% respectively. Determine gender. For example, the first analysis result is male, the second analysis result is female, and the third analysis result is female. Then, the weight percentage of the child's gender being male is calculated as 100×45%=45 (because only the analysis result of the timbre value is male). The weight percentage of the child's gender being female is calculated as (100×35%) + (100×25%) = 55 (because the analysis results of the pitch value and the speaking speed value are both female). 45 is less than 55 (male is less than female), that is, the result is female, and female is determined as the child's identity data.

[0086] S20033, when the emotion data indicates that the current emotion of the child is a bad emotion, and the child identity data indicates that the child's gender is male, the aroma diffuser is controlled to diffuse the aroma according to the male child's fragrance data; wherein the male child's fragrance data is used to indicate the aroma type and aroma adjustment speed diffused by the aroma diffuser preset according to the male child's preferences.

[0087] Exemplarily, the type of aroma diffused by the aroma device preset according to the male child's preferences indicated by the male child's aroma data can be an aroma type set according to the fruit aroma or food aroma that the male child likes, and the aroma adjustment speed can be adjusted according to the child's age and mood.

[0088] S20034, when the emotion data indicates that the current emotion of the child is a bad emotion, and the child identity data indicates that the child's gender is female, the aroma diffuser is controlled to diffuse the aroma according to the female child's aroma data; wherein the female child's aroma data is used to indicate the aroma type and aroma adjustment speed diffused by the aroma diffuser preset according to the male child's preferences.

[0089] Exemplarily, this step is similar to step S20033, and the type of aroma diffused by the aroma diffuser preset according to the female child's preferences indicated by the female child's aroma data can be an aroma type set according to the female child's favorite fruit aroma or food aroma, and the aroma adjustment speed can be adjusted according to the child's age and mood.

[0090] Such a setting can soothe children's emotions through fragrance, and can reduce the situation where the main driver is disturbed by children's noise, so as to improve the driving safety of the main driver, enhance the passenger comfort and reduce the discomfort of the ride.

[0091] In a possible implementation, S200, according to the riding situation of the passengers in the car, controlling the aroma device to diffuse the aroma includes: S20001: If the emotion data indicates that the child is in a good mood, the aroma device is controlled to diffuse the aroma according to the spouse's preset data or the owner's preset data.

[0092] It can be understood that when the seating situation of the occupants in the car indicates that there is a main driver who is the car owner in the first seating position, a co-pilot who is the car owner's spouse in the second seating position, and a rear passenger in the third seating position who is a male child or a female child in a good mood, the aromatherapy device is preferentially controlled to operate with the preset fragrance type and fragrance diffusion speed according to the spouse's preset data or the owner's preset data; the priority method of preferentially controlling the aromatherapy device according to the spouse's preset data or the owner's preset data may be to make a priority selection based on the current status or mood of the car owner or the car owner's spouse.

[0093] S20002: If the seating data indicates that there is no child in the third seating position, the aroma diffuser is controlled to diffuse aroma according to the spouse preset data or the owner preset data.

[0094] It can be understood that when the seating situation of the occupants in the car indicates that there is a main driver who is the car owner in the first seating position, there is or is not a co-pilot who is the car owner's spouse in the second seating position, and there is no child in the third seating position, the aromatherapy device is preferentially controlled to operate with the preset fragrance type and fragrance diffusion speed according to the spouse preset data or the owner preset data; wherein the priority method of preferentially controlling the aromatherapy device according to the spouse preset data or the owner preset data may be to make a priority selection based on the current state or mood of the car owner or the car owner's spouse.

[0095] With this setting, when a child is in a bad mood, the emotional care of the people in the car can be enhanced, helping the child to relieve negative emotions, effectively improving their emotional state, reducing the interference factors of children's crying to the main driver while driving, ensuring driving safety, and further improving driving safety; when the child is in a good mood, the fragrance is adjusted according to the preset data of the owner or spouse to meet the owner's needs for the driving environment and improve the overall riding experience.

[0096] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
