[0018] Figure 3 It is a schematic structural diagram of the vehicle of one embodiment of the present application. Detailed Description of the Embodiments

[0019] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are only examples of the devices consistent with some aspects of the present application as detailed in the appended claims.

[0020] Next, with reference to the drawings, the on-vehicle fragrance adjustment method, adjustment device and vehicle of each embodiment of the present application will be described in detail. Without conflict, the features in the following embodiments and implementation manners can be combined with each other.

[0021] In traditional Chinese medicine, the aroma of herbs can condition the human body through aromatherapy, and has various effects such as relieving stress, refreshing the mind, calming the nerves, and relieving fatigue. Based on this, the present application proposes an on-vehicle fragrance made by mixing traditional Chinese herbal medicine fragrance materials based on traditional Chinese medicine theory to regulate the physical and mental health of drivers, and combines human body recognition to adjust the fragrance formula in real time according to the physical condition, mood and needs of users, so as to achieve the most suitable curative effect.

[0022] Figure 1The flowchart of the in-vehicle fragrance adjustment method according to an embodiment of the present application is disclosed. As Figure 1 shown, the in-vehicle fragrance adjustment method according to an embodiment of the present application may include steps S1 to S3.

[0023] In step S1, obtain the current physiological and psychological state data of the user inside the vehicle.

[0024] The current physiological and psychological state data of the user can be obtained through one or more of a contact sensor scheme, a visual recognition scheme, and a driving behavior pattern scheme.

[0025] For the contact sensor scheme, one or more of the data such as the user's heart rate, changes in skin conductivity, and body temperature can be obtained through a contact sensor.

[0026] For example, the user's heart rate can be detected through a sensor (such as a photoelectric sensor) built into the seat or the steering wheel. The user's psychological state is reflected by the heart rate. A high heart rate may indicate a state of tension or anxiety; a low heart rate may indicate a state of relaxation.

[0027] For example, skin conductance response measurements can be performed through electrode sensors on the surface of the steering wheel or the seat to obtain changes in skin conductivity. The emotional fluctuations of the user are reflected by the changes in skin conductivity. For example, rapid changes in skin conductivity may indicate psychological stress or emotional excitement.

[0028] For example, the user's body temperature can be detected through a temperature sensor built into the seat or on the edge of the steering wheel. The user's physical state is reflected by the body temperature. For example, an increase in body temperature may indicate physiological stress or health problems.

[0029] For the visual recognition scheme, the in-vehicle camera can be used to detect the user's facial image, and visual algorithms can be used to identify the user's emotions, heart rate, blood oxygen, etc. states, reflecting the current various physiological indicators and psychological states of the user.

[0030] For example, the user's facial expression can be obtained by using facial recognition technology based on the facial image of the user captured by the camera, and the user's emotional state can be obtained through facial expression analysis, such as happy, sad, angry, surprised, etc. Certain expressions, such as frowning, may indicate annoyance or anxiety; a smile may indicate relaxation or happiness.

[0031] For example, eye movement tracking can be performed based on the facial image of the user captured by the camera to monitor and obtain the pupil position and blink frequency of the user. Frequent blinking or pupil dilation may indicate psychological stress or fatigue.

[0032] For example, based on the facial image of the user captured by the camera, the heart rate and / or blood oxygen saturation data of the user can be estimated from the change in facial color through image analysis technology. The health status and stress level of the user can be evaluated through the heart rate and / or blood oxygen data.

[0033] For the driving behavior pattern solution, a behavior pattern model can be established in advance through data such as the vehicle speed, acceleration, and steering wheel angle of the vehicle, etc., to analyze the regular and irregular driving behaviors of the driver. Then, the current driving data of the vehicle can be obtained, and the current driving data can include one or more of the vehicle speed, acceleration, and steering wheel angle; the current driving data is input into the pre-established behavior pattern model, and the current driving behavior pattern of the user is obtained through the analysis of the behavior pattern model, so as to identify the physiological and psychological states of the user. For example, frequent acceleration and hard braking may indicate the uneasiness or impatience of the driver; unstable or frequent steering wheel rotation may indicate anxiety or distraction; aggressive driving may be related to a high stress level; stable driving may indicate that the driver is in a relatively relaxed state.

[0034] In step S2, the current physiological and psychological state data of the user obtained in step S1 is input into the standard fragrance adjustment model established based on the efficacy of Chinese herbal fragrance materials and traditional Chinese medicine theory, and a fragrance formula matching the current physiological and psychological state data is output through the standard fragrance adjustment model, where the fragrance formula includes fragrance mixing materials and their proportions.

[0035] In some embodiments, the current environmental data is also obtained, and the current environmental data can also be used as one of the inputs of the standard fragrance adjustment model. Therefore, in this case, the standard fragrance adjustment model can output a fragrance formula matching the current physiological and psychological state data based on the current physiological and psychological state data and combined with the current environmental data.

[0036] In step S3, the fragrance is released in the vehicle according to the fragrance formula output in step S2 to adjust the physical and mental health of the user.

[0037] The vehicle-mounted fragrance adjustment method of the present application may further include step S4. In step S4, a standard fragrance adjustment model can be established in advance.

[0038] In some embodiments, step S4 may further include steps S41 to S42.

[0039] In step S41, a fragrance database is constructed in advance based on traditional Chinese medicine theory. The fragrance database divides the Chinese herbal fragrance materials according to their efficacy based on traditional Chinese medicine theory. The fragrance database includes the basic information and formulation schemes of various Chinese herbal fragrance materials.

[0040] The fragrance database contains a variety of Chinese herbal fragrance materials, and each fragrance material has a detailed description of its efficacy. Moreover, the fragrance database provides the compatibility rules and proportion principles among the fragrance materials.

[0041] I. The Efficacy Classification System of Fragrances under Traditional Chinese Medicine Theory

[0042] (1) Division of Fragrance Efficacy Based on Constitution Differentiation

[0043] Traditional Chinese medicine's constitution theory divides the human body into eight types, and fragrance compatibility needs to follow the principle of "applying fragrance according to syndrome differentiation":

[0044] Yin-deficient constitution (insufficient body fluids): It is advisable to use sweet and cool moistening fragrance materials such as lavender and chamomile, which can nourish yin and soothe the nerves and clear away deficiency heat;

[0045] Yang-deficient constitution (weak yang qi): Cinnamon, clove and other pungent and warm spices are recommended, combined with tropical floral notes, which can warm the mingmen and stimulate yang qi;

[0046] Qi-stagnant constitution (unsmooth qi movement): Aromatic qi-regulating fragrances such as rose and bergamot can soothe the liver and relieve depression and promote the secretion of "happy polyphenols";

[0047] Phlegm-damp constitution (internal accumulation of damp turbidity): Aromatic dampness-resolving Chinese medicinal materials such as patchouli and atractylodes, combined with cool fragrance notes such as mint, can arouse the spleen and promote diuresis and inhibit phlegm turbidity;

[0048] Blood-stasis constitution (blocked blood vessels): Blood-activating fragrance materials such as chuanxiong and frankincense, combined with pungent fragrance notes, can warm the meridians and dredge collaterals and improve microcirculation.

[0049] (2) The Fragrance System Based on the Efficacy of Traditional Chinese Medicine

[0050] According to the classification standard of "Traditional Chinese Medicine Aromatherapy", a six-dimensional efficacy system is formed:

[0051]

[0052]

[0053] Special compatibility example: Angelica dahurica belongs to both the exterior-resolving category (expelling wind and cold) and the stasis-removing category (detumescence and discharging pus), reflecting the characteristic of "one medicine with multiple effects".

[0054] II. The Compatibility Rules of Fragrance Materials

[0055] (1) Core Compatibility Principles

[0056] The combination of scents is in harmony: Following the theory of "harmonizing scents and flavors" in the Inner Canon of Huangdi, for example:

[0057] The combination of pungent and cool (mint + chrysanthemum): It can relieve the exterior without damaging yin;

[0058] The combination of bitter and pungent (tangerine peel + clove): It can regulate qi and relieve stagnation;

[0059] Sweet-acid nourishing yin (rose + smoked plum): Nourishing yin and moistening dryness;

[0060] Mutual generation and restriction of the five elements: For example:

[0061] Wood generating fire: Sandalwood (wood) combined with frankincense (fire) enhances the power of warming and dredging;

[0062] Metal generating water: Angelica dahurica (metal) combined with agarwood (water) realizes the dual regulation of the lung and kidney;

[0063] Avoiding restriction: Avoid using cinnamon (fire) and mint (metal) together to cause qi disorder;

[0064] Ascending, descending, floating and sinking: For example

[0065] Combination for ascending lucidity: Bupleurum + mint (ascending yang qi);

[0066] Combination for descending turbidity: Agarwood + magnolia bark (descending phlegm turbidity);

[0067] Balanced compatibility: Sandalwood (ascending) combined with frankincense (descending) maintains the dynamic balance of qi movement.

[0068] (2) Dosage ratio system

[0069] Adopt the four-level structure of "sovereign, ministerial, assistant, and courier":

[0070] Sovereign drug (40%): Dominating the efficacy, such as lavender in the calming sachet;

[0071] Ministerial drug (30%): Strengthening the main efficacy, such as cooperating with semen platycladi to enhance calming;

[0072] Assistant drug (20%): Harmonizing the properties of drugs, such as adding licorice to balance cold and heat;

[0073] Courier drug (10%): Guiding the meridian and reporting the effect, such as borneol promoting transdermal absorption;

[0074] Advanced ratio techniques:

[0075] Adjustment according to physical constitution differences: For those with yang deficiency, the proportion of the sovereign drug is increased to 50% (such as cinnamon);

[0076] Adjustment according to seasonal fluctuations: In summer, the proportion of the assistant drug is increased by 10% (such as adding mint to prevent heatstroke);

[0077] Principle of carrier adaptation: The proportion of fat-soluble components (such as sandalwood) in the aromatherapy oil agent needs to reach more than 60%.

[0078] Thus, the Chinese herbal medicine fragrance materials can be classified according to their effects by combining traditional Chinese medicine theory and the effects of Chinese herbal medicine fragrance materials.

[0079] Optionally, it is also possible to classify the Chinese herbal medicine fragrance materials according to the following effects by combining traditional Chinese medicine theory:

[0080] 1. Regulate qi and blood:

[0081] - Tonify qi: Such as ginseng, astragalus, wolfberry, etc., which are suitable for people with qi deficiency, enhancing spirit and physical strength;

[0082] - Tonify blood: Such as angelica, red date, wolfberry, which are suitable for the state of blood deficiency, enhancing vitality;

[0083] 2. Soothe emotions:

[0084] - Soothing nerves: Such as chrysanthemum, lavender, cypress, which help soothe anxiety and relax nerves;

[0085] - Refreshing: Such as mint, citrus, rosemary, which help refresh the mind and relieve fatigue;

[0086] 3. Warm yang and dispel cold:

[0087] - Warming yang: Such as cinnamon, tangerine peel, ginger, etc., which are suitable for users with cold body constitution, improving blood circulation;

[0088] 4. Detoxify and clear heat:

[0089] - Clear heat and detoxify: Such as honeysuckle, chrysanthemum, lotus leaf, which help clear heat and reduce internal heat, expelling dampness and toxins in the body.

[0090] It can be understood that the above are only some examples of the utility classification of Chinese herbal medicine fragrance materials in this application. However, the utility classification of Chinese herbal medicine fragrance materials in this application is not limited to this, and more subtle or comprehensive utility classifications can be made according to actual needs. Any scheme for classifying the utility of Chinese herbal medicine fragrance materials in combination with traditional Chinese medicine theory will be within the protection scope of this application.

[0091] The mixing principle of fragrance materials can be carried out according to traditional Chinese medicine theories such as the generation and restriction of the five elements and the balance of yin and yang. For example, when yang qi is insufficient, warm yang fragrance can be selected; if there is excessive internal fire in the body, fragrance for clearing heat and detoxifying can be selected.

[0092] The proportioning between fragrance materials can be determined according to the physiological state of the user and / or according to the user's mood. Through the user's physiological data, such as temperature, heart rate, pressure, etc., the proportioning of the fragrance is dynamically adjusted. For example, in a high-temperature state, the proportion of cool and detoxifying fragrance is increased, and the proportion of warm yang fragrance is reduced. If the user feels anxious, the proportion of soothing nerves fragrance can be increased; if the user feels fatigued, the proportion of refreshing fragrance can be increased.

[0093] In step S42, based on the physiological and psychological state data of people, using the data provided by the fragrance database, a standard fragrance adjustment model can be established through machine learning algorithms.

[0094] According to the physiological and psychological states of people, the model can select appropriate types of fragrances from the fragrance database, and according to the fragrance compatibility rules and proportion principles given by the fragrance database, give multiple fragrance formula combinations. Through machine learning algorithms, the model is continuously trained and optimized to select the corresponding fragrance formula that conforms to the physiological and psychological states of people.

[0095] In some embodiments, the in-vehicle fragrance adjustment method of the present application may further include step S5 and step S6.

[0096] In step S5, the preferences and / or requirements of the user for fragrance use can be obtained.

[0097] Optionally, the historical fragrance use data of the vehicle and / or the feedback of the user can be obtained, and the preferences of the user for fragrance use can be analyzed based on the historical fragrance use data of the vehicle and / or the feedback of the user.

[0098] In step S6, the standard fragrance adjustment model can be updated according to the preferences and / or requirements of the user, so that the fragrance formula output by the standard fragrance adjustment model can meet the personalized needs of the user. The update of the standard fragrance adjustment model can include, for example, appropriate adjustment of materials and proportions, etc.

[0099] For example, when the standard fragrance adjustment model selects fragrance materials from the fragrance database for mixing, it starts to consider the user's usage preferences. Among the fragrance materials with the same efficacy, the fragrance materials liked by the user are preferentially selected for mixing. Or, without changing the basic efficacy, the proportion of the fragrance materials liked by the user can be appropriately increased for fragrance mixing, etc. Thus, while regulating the physiological and psychological states of the user, the preference requirements of the user for the fragrance are satisfied as much as possible, and the comfort of the user is improved.

[0100] In some embodiments, there can be multiple corresponding fragrance formulas selected by the standard fragrance adjustment model that conform to the physiological and psychological state data of people. In this case, the standard fragrance adjustment model can score the multiple fragrance formulas respectively through machine learning by combining mechanisms such as the historical fragrance formula usage situation, the user's usage preferences, the user's usage requirements, and the user's usage feedback, give a score corresponding to each fragrance formula, and can sort the multiple fragrance formulas according to the high and low scores. Finally, the standard fragrance adjustment model can output the fragrance formula with the highest score. Of course, in other embodiments, the multiple fragrance formulas can also be divided into priorities, sorted according to the priority order, and finally the fragrance formula with the highest priority is output.

[0101] Optionally, usage data of the historical fragrance formula of the vehicle and / or feedback from the user regarding the used fragrance formula can be obtained; and based on the usage data of the historical fragrance formula and / or the user's feedback, the score of the fragrance formula in the standard fragrance adjustment model can be adjusted. Thus, the standard fragrance adjustment model can be dynamically updated according to the user's preferences and / or needs to meet the user's personalized needs and improve comfort.

[0102] For example, when the fragrance formula output according to the standard fragrance adjustment model releases fragrance in the vehicle, if the user directly turns off the fragrance release function, it means that the user may not like the fragrance formula, or, for example, the feedback given through the user's voice input is that they do not like the fragrance formula. Then, in this case, the standard fragrance adjustment model can reduce the score of this fragrance formula through machine learning. Thus, when the user is in the same state next time, the standard fragrance adjustment model will not recommend outputting this fragrance formula.

[0103] The in-vehicle fragrance adjustment method of the present application can be based on traditional Chinese medicine theory, mix different Chinese herbal medicine fragrance materials, and can dynamically adjust the fragrance formula in real time according to the user's physiological and psychological states, achieving the curative effect of adjusting the user's current physiological and psychological states, helping the user relieve stress, fatigue, anxiety and other problems, regulating the user's physical and mental health, and improving the user's comfort.

[0104] In addition, the in-vehicle fragrance adjustment method of the present application can update the standard fragrance adjustment model according to the user's preferences and / or needs for fragrance use. Thus, personalized fragrance adjustment of the fragrance formula by the user can be realized, and further personalized and precise treatment and soothing effects can be achieved to meet the needs of different groups of people.

[0107] The standard fragrance adjustment model 202 can be established based on the efficacy of Chinese herbal medicine fragrance materials and traditional Chinese medicine theory. The standard fragrance adjustment model 202 is used to receive the current physiological and psychological state data of the user as input and output a fragrance formula that matches the current physiological and psychological state data. The fragrance formula includes fragrance mixing materials and their ratios.

[0108] The release module 203 can release fragrance in the vehicle according to the fragrance formula to adjust the physical and mental health of the user.

[0109] The in-vehicle fragrance adjustment device of the present application can have beneficial technical effects similar to those of the in-vehicle fragrance adjustment method described above. Therefore, it will not be elaborated here.
