Description

Technical Field

[0001] The present application relates to the field of smart cockpits, and in particular to a method, device and system for controlling cabin odor. Background Art

[0002] The air circulation in the vehicle cabin is poor and odor is easily generated in a closed vehicle cabin for a long time, which will cause discomfort to the driver and passengers, accelerate fatigue and even affect driving safety. In order to improve this situation, a fragrance system is usually installed in the vehicle cabin. The system can release fragrance to form a unique smell in the cabin to purify the air inside the cabin and even refresh the mind, improving the riding experience of the passengers.

[0003] However, the fragrance system in the related art is usually only used to release fragrances with fixed smells, so the smell in the cabin is often single, and the olfactory experience of the passengers is relatively monotonous and boring, which needs to be improved. Summary of the invention

[0004] In view of this, the present application provides a cabin odor control method, device and system to address the deficiencies in the related art.

[0005] Specifically, the present application is implemented through the following technical solutions:

[0006] According to a first aspect of the present application, a cabin odor control method is provided, the method being applied to a controller installed in a vehicle, the vehicle also being equipped with a fragrance system, the method comprising:

[0007] determining external aromas in the vehicle exterior space, the external aromas comprising a first aroma actually present in the exterior space and / or a second aroma expected to be present in the exterior space, the external aromas being emitted by an odor source in the exterior space;

[0008] The fragrance system is controlled to release a target fragrance into the cabin of the vehicle, wherein the target fragrance includes the external fragrance and / or a similar fragrance having a similar smell to the external fragrance.

[0009] According to a second aspect of the present application, a cabin odor control system is provided, the system comprising a controller and a fragrance system installed in a vehicle, wherein:

[0010] The controller is used to determine external aromas in the external space of the vehicle, wherein the external aromas include a first aroma actually present in the external space and / or a second aroma expected to exist in the external space, and the external aromas are emitted by an odor source in the external space;

[0011] The fragrance system is used to release target fragrance into the cabin of the vehicle under the control of the controller, and the target fragrance includes the external fragrance and / or similar fragrance with a similar smell to the external fragrance.

[0012] According to a third aspect of the present application, a cabin odor control device is provided, the device is applied to a controller installed in a vehicle, the vehicle is also equipped with a fragrance system, and the device includes:

[0013] an aroma determination unit, configured to determine external aromas in the vehicle external space, wherein the external aromas include first aromas actually present in the external space and / or second aromas expected to exist in the external space, and the external aromas are emitted by an odor source in the external space;

[0014] The aroma release unit is used to control the aroma system to release target aromas into the cabin of the vehicle, wherein the target aromas include the external aromas and / or similar aromas with similar odors to the external aromas.

[0015] The technical solution provided by the embodiments of the present application may have the following beneficial effects:

[0016] In the odor control scheme described in the present application, the controller installed in the vehicle can first determine the external aroma in the external space of the vehicle, that is, the first aroma actually existing in the external space and / or the second aroma expected to exist, and then control the fragrance system installed in the vehicle to release the target aroma composed of the external aroma and / or its similar aroma into the cabin, thereby distributing an odor corresponding to the external aroma in the cabin.

[0017] In this solution, the controller installed in the vehicle determines the first aroma actually contained in the air outside the vehicle and / or the second aroma expected to be contained, and then controls the fragrance system to release the above aroma or similar aroma close to its smell to emit the smell corresponding to the external aroma in the cabin. It can be seen that this solution can flexibly adjust the smell in the cabin according to the actual environment around the vehicle through the cooperation between the controller and the fragrance system, so as to achieve the smell following effect that the smell in the cabin changes with the changes in the surrounding environment of the vehicle (for example, when the vehicle is parked next to an osmanthus tree with osmanthus flowers, the cabin will be full of osmanthus fragrance; and when the vehicle is driving on a grassland / grass with green grass, the cabin will be full of grass smell, etc.), creating an olfactory environment in the cabin that is the same (or close) as the space outside the cabin. Obviously, compared with the relevant technology, this solution can be applied to scenes where it is not suitable to open the window or turn on the external circulation function (such as raining / snowing outside the car, poor air quality outside the car, etc.), and the olfactory perception of the occupants in the cabin can be enriched without the occupants opening the window, thereby improving their riding experience.

[0024] Figure 1 FIG. 1 is a schematic diagram of the structure of a cabin odor control system provided by an exemplary embodiment. Figure 1 As shown, the system may include a controller 111 and a fragrance system 112 installed in the vehicle 11. The controller 111 may be a domain controller in the vehicle 11, such as a domain controller of a cockpit domain (or intelligent information domain); or it may be an independent controller installed in the vehicle 11 for controlling the cabin odor. The embodiment of the present application does not limit its type and quantity. The fragrance system 112 may be composed of a container for holding fragrance (or fragrance) (such as fragrance capsules, fragrance bottles / boxes, etc.), a movement mechanism for releasing fragrance (such as motors, switches, etc.), and a pipe for transmitting fragrance (such as an air pipe, an air outlet, etc.), wherein the opening of the pipe may be set at a suitable position of the cockpit 113 (such as an air conditioning outlet, etc.) so as to release fragrance into the cockpit 113. Exemplarily, the fragrance system 112 may release fragrance through a small sprayer or a dispenser. In addition, a passenger 12 may be seated in the cockpit 113.

[0025] Among them, the vehicle described in this application (such as vehicle 11) can be a pickup truck, a sedan, an SUV (Sport Utility Vehicle), a motorhome, a truck, etc. in terms of its functional form; in terms of its power form, it can be a fuel vehicle or a new energy vehicle (such as a hybrid vehicle, a pure electric vehicle, a hydrogen energy vehicle, a methanol energy vehicle, etc.), and the present invention does not limit the specific form of the vehicle. In addition, this application does not limit the number of seats and their layout in the cockpit 113, which can be set according to actual needs. Of course, there is no restriction on the number of passengers 12 in the cockpit 113 and their seating positions.

[0026] In addition to the controller 111 and the fragrance system 112, the cabin odor control system may also include an image acquisition device 114 and an odor recognition device 115. The image acquisition device 114 may include a vehicle-mounted camera (such as Figure 1 A camera installed on the vehicle 11) or an electronic device used by the passenger 12 ( Figure 1 Not shown) etc. Figure 1 As shown, the vehicle-mounted camera can be set on the roof and front of the vehicle 11, and of course, it can also be set at any other position of the vehicle 11 (such as a parking space, a side mirror bracket, etc.), which will not be repeated. Exemplarily, the electronic device used by the occupant 12 can be a mobile phone, a PC (Personal Computer), a workstation (Work Station), a PDA (Personal Digital Assistants), a wearable device (such as smart glasses, smart watches, etc.), a VR (Virtual Reality) device, an AR (Augmented Reality) device, etc., and one or more embodiments of the present application are not limited to this. The odor recognition device 115 (or "electronic nose") can be composed of an odor sensor and a necessary signal processing module, which can be used to detect and identify the odor molecules contained in the gas flowing through the odor sensor, and finally determine the aroma contained in the gas. Among them, the odor sensor can work based on the chemical reaction principle or the electrochemical principle, and can sense and detect odors, gases and volatile organic compounds in the surrounding air. The specific working principle can be found in the records in the relevant technology.

[0027] In addition, the vehicle may also be equipped with a communication device 116 and an interaction device 117 ( Figure 1The controller 111 can communicate with other related parties (such as the electronic devices used by the aforementioned passengers 12, the server 13 in the cloud for realizing a certain function, etc.) through the communication device 116. The server 13 can be a physical server including an independent host, or a virtual server carried by a host cluster, a cloud server, etc. It should be noted that although Figure 1 Only one server 13 is shown, but the server can be used to implement multiple functions, such as providing positioning services and date services to the server; or, the server 13 can actually include multiple servers, such as a server for providing positioning services and a server for providing date services, which will not be repeated. The passenger 12 can interact with the vehicle through the interactive device 117, such as opening the fragrance function setting interface by performing a touch operation on the central control screen of the vehicle 11 (the interactive device 117 is the central control screen in this case), adjusting the fragrance concentration by performing a preset action in a predetermined area in the cabin 113 (the interactive device 117 is a somatosensory device such as a camera installed in the cabin in this case), and adjusting the fragrance concentration by issuing voice control (the interactive device 117 is a sound receiving device such as a microphone installed in the cabin in this case).

[0028] The network 10 for interaction between the vehicle 11 and the server 13 can be based on the communication mode supported by the corresponding device, and the specific type of wireless network can be selected to achieve communication, and this specification does not limit this. For example, the vehicle 11 can establish a wireless connection with the mobile phone used by the passenger 12 through communication modes such as Bluetooth, wifi, NFC (Near Field Communication) to achieve communication, and can establish a wireless connection with the server 13 through communication modes such as wifi, 4G, 5G, etc. to achieve communication, which will not be repeated.

[0029] With the aforementioned Figure 1 The vehicle 11 shown corresponds to, Figure 2 1 is a topological structure diagram of various devices inside a vehicle shown in an embodiment of the present application. Figure 2 As shown, the vehicle 11 includes, in addition to the controller 111 and the fragrance system 112, an image acquisition device 114, a communication device 116, and an interactive device 117. The fragrance system 112, the image acquisition device 114, the communication device 116, and the interactive device 117 are electrically connected to the controller 111 to interact with the controller 111 to implement the cabin odor control solution described in the embodiment of the present application. It should also be noted that the fragrance system 112 can be used to manage a variety of aromas, such as Figure 2The aromas 1 to n (where n≥2) shown in the figure can emit corresponding odors (including the target odors described below) in the cabin after being combined and released according to different component concentrations. In addition, in order to ensure that the gas released by the fragrance system is harmless to the passengers, the above-mentioned aromas can be made of food-grade materials. In order to improve the environmental protection level, natural ingredients and degradable materials can be used to make the above-mentioned aromas, and the embodiments of the present application are not limited to this.

[0030] The present application proposes a cabin odor control system, which includes a controller and a fragrance system installed in a vehicle, wherein:

[0031] The controller is used to determine external aromas in the external space of the vehicle, wherein the external aromas include a first aroma actually present in the external space and / or a second aroma expected to exist in the external space, and the external aromas are emitted by an odor source in the external space;

[0032] The fragrance system is used to release target fragrance into the cabin of the vehicle under the control of the controller, and the target fragrance includes the external fragrance and / or similar fragrance with a similar smell to the external fragrance.

[0033] The specific working method of the system can be found in the detailed description of the embodiments below, which will not be described here.

[0034] Figure 3 is a flow chart of a cabin odor control method shown in an embodiment of the present application, the method is applied to a controller (such as Figure 1 The vehicle is also equipped with a fragrance system (such as Figure 1 The method includes the following steps 302-304.

[0035] Step 302 : determining external aromas in the vehicle external space, wherein the external aromas include first aromas actually existing in the external space and / or second aromas expected to exist in the external space, and the external aromas are emitted by an odor source in the external space.

[0036] The external space of the vehicle described in this application refers to the physical space outside the vehicle cabin, and the embodiments of this application do not limit the position, size, shape, etc. of this space. There may be certain objects that can emit odors in the external space, and the embodiments of this application refer to these objects as "odor sources". Specifically, the above-mentioned odor sources will release aromatic substances into the external space, and these aromatic substances will diffuse into the air of the external space, thereby forming corresponding odors in the external space. For example, a flowering osmanthus tree will release aromatic substances with the fragrance of osmanthus, a flowering peony will release aromatic substances with the fragrance of peony, a lawn mowed by a lawn mower will release aromatic substances with the smell of grass, a barbecue stall that is grilling food will release aromatic substances with the aroma of spices and food, etc., which will not be repeated.

[0037] It should be noted that the "aromatic substance" or "fragrance" described in the embodiment of the present application is not limited to substances that form "fragrance" in the conventional sense, but can be captured by the human olfactory system and recognized as substances of any taste, and the embodiment of the present application does not limit this. In other words, although the substance released by the fragrance system in the embodiment of the present application is "aromatic substance", since the definition of "fragrance" and "odor" is highly subjective, it does not mean that the odor emitted by the above substances in the cabin will definitely be considered as "fragrance" by the occupants in the cabin, and it may also be some unique odors or even "odors". However, it should be emphasized that this solution can ensure that the target aroma released in the cabin is the external aroma in the external space (specifically the actual first aroma and / or the expected second aroma) or a similar aroma, so as to ensure that the odor emitted by the released target aroma in the cabin is the same or close to the odor emitted by the external aroma outside the vehicle, so that the occupants can smell the same or close odor in the cabin even if they do not open the car window or only turn on the internal circulation, thereby improving their olfactory experience and the ability to perceive external odors. Moreover, the external fragrance released in the cabin in the embodiment of the present application should not contain toxic, harmful, allergenic and other ingredients to avoid causing harm to the health of the occupants or affecting the riding comfort of the occupants.

[0038] In one embodiment, the controller may execute the scheme in real time when the vehicle cabin is powered on, that is, the external aroma in the external space may be determined in real time after the cabin is powered on.

[0039] In another embodiment, considering that there may be no passengers in the cabin after the cabin is powered on, and the cabin odor is controlled to provide a more comfortable olfactory environment for the passengers in the cabin, in order to avoid ineffective odor control, the scheme can be executed only when the passengers have a need. For example, the controller can determine the external aroma in the external space when there are passengers in the cabin, wherein the vehicle can be equipped with corresponding sensors (such as infrared sensors facing the seats, pressure sensors under the seats, etc.), and at this time, it can be determined whether there are passengers in the cabin at the current moment according to the detection results of the sensors. In this way, the cabin odor can be controlled by this scheme when there are passengers in the cabin, and the control can be stopped when there are no passengers in the cabin, thereby reducing the cost of the system for controlling the cabin odor (computational cost, power cost, and aroma cost, etc.), and improving the efficiency of odor control.

[0040] For another example, the controller may also determine the external aroma in the external space when a passenger will enter the cabin within a preset time after the current moment. Exemplarily, the vehicle may have a reservation boarding function, that is, the user may make an appointment with the vehicle for the passenger to board the vehicle (such as the driver pre-setting "boarding at 7:30 a.m. on weekdays" in the vehicle system of the vehicle, or any passenger initiates a reservation boarding instruction to the vehicle "boarding in 5 minutes" through his own electronic device, etc.); based on this, the controller may determine whether a passenger will enter the cabin within a preset time after the current moment through the current moment and the aforementioned boarding time. In this way, the cabin odor control system can control the odor in the cabin in advance when the passenger is about to board the vehicle, thereby creating an olfactory environment in the cabin that matches the current landscape for the user in advance, avoiding the odor in the car being dirty when the user just gets on the car, and helping to improve the riding experience of the passenger after getting on the car.

[0041] For another example, in view of the fact that certain activities of the occupants in the cabin (such as smoking, moxibustion, sneezing, etc.) may affect the air quality in the cabin, the controller can also monitor the degree of pollution of the air in the cabin, and determine the external aroma in the external space when the degree of pollution is not less than the degree threshold. Exemplarily, the pollutant concentration value in the air in the cabin can be monitored, that is, the concentration of various pollutants in the air is directly used to characterize the degree of pollution of the air in the cabin. Alternatively, the air quality index (Air Quality Index, AQI for short, or air index) in the cabin can also be calculated based on the detected pollutant concentration value. Among them, the above-mentioned pollutants may include at least one of the following: sulfur dioxide (SO2), nitrogen dioxide (NO2), inhalable particulate matter (PM10), fine particulate matter (PM2.5), ozone (O3) and carbon monoxide (CO), etc. Of course, the vehicle should also be equipped with sensors for detecting the above-mentioned pollutants, and be provided with necessary structures that allow the air in the cabin to contact the sensors, which will not be repeated one by one. It is understandable that the pollution level is not less than the level threshold, indicating that the air in the cabin is already relatively polluted. At this time, controlling the smell in the cabin through the solution described in the present application can improve the air quality in the cabin to a certain extent through odor control and enhance the olfactory experience of the passengers. Of course, it is also possible to directly control the opening of the external circulation and / or control at least one window to open when the pollution level is not less than the level threshold, so as to improve the air quality in the cabin through ventilation, which will not be repeated.

[0042] Determining the external aroma in the external space is actually determining the first aroma actually existing in the external space, and / or determining the second aroma expected to exist in the external space. The difference between the first aroma and the second aroma is that the first aroma is an aroma that can be determined by the controller and exists in the air of the external space, that is, an aroma that can be actually detected; and the second aroma is an aroma that should theoretically exist in the air of the external space, but the vehicle does not detect the aroma or does not detect the aroma. It is understandable that the external aroma determined by the controller may only include the first aroma, may only include the second aroma, and may also include the first aroma and the second aroma at the same time. In addition, the first aroma and the second aroma may both contain at least one aroma, and the aromas contained in the two may be completely different, or may be partially or even completely the same, and the embodiment of the present application does not limit this. For any odor source actually existing in the external space, if the aroma released by it is detected by the vehicle, the aroma is regarded as the first aroma; if the vehicle does not detect the odor outside the cabin or detects it but does not detect the aroma, the aroma will be regarded as the second aroma.

[0043] It is understandable that the first fragrance actually present in the air of the external space can form a corresponding smell (hereinafter referred to as the actual smell) in the space, and the second fragrance (theoretically) should also be able to form a corresponding smell (hereinafter referred to as the expected smell) in the air of the external space.

[0044] Among them, the external aroma described in this specification can be any type of aroma that can be obtained by natural extraction or artificial synthesis. Exemplarily, the external aroma can include at least one of the following: plant flower aroma (such as terpene compounds such as phenylethyl alcohol and linalool that produce flower aroma, ester compounds such as methyl salicylate that produce flower aroma), fruit aroma (such as terpene compounds such as limonene and myrcene that produce fruit aroma), herbal aroma (such as alcohol compounds such as menthol that produce herbal aroma, aldehyde compounds such as geranial (i.e., citral a) and neral (i.e., citral b), etc.), plant essential oils (such as lavender essential oil, rose essential oil, jasmine essential oil, etc.), synthetic fragrances (such as coumarin, musk ketone, ionone, etc.), natural aroma (such as vanillin, limonene, α-pinene, β-pinene, etc.), artificial synthetic aroma (such as lily of the valley aldehyde, jasminaldehyde, etc.), no more details.

[0045] In one embodiment, the first aroma contained in the air outside the vehicle can be identified (or detected) by an odor recognition device (i.e., an "electronic nose"). For example, when the vehicle itself is equipped with the odor recognition device, the controller can call the odor recognition device to identify the first aroma. Alternatively, when the odor recognition device is installed on other electronic devices, the vehicle can communicate with the electronic device to obtain the first aroma recognized by the odor recognition device called by the electronic device. Among them, the electronic device can be a drone, a remote control car, or other equipment that has a wireless connection with the vehicle, or a mobile phone, a wearable device, or other equipment of an outside user, and the embodiment of the present application is not limited to this. In addition, the working principle and specific working method of the odor recognition device can refer to the records in the relevant technology, which will not be repeated here. Obviously, the first aroma recognized by the above method is an aroma that actually exists in the air of the external space and forms an actual odor. By controlling the fragrance system to release the first aroma in the cabin, the above actual odor can also be formed in the cabin, so that the occupants in the cabin can smell the real odor that actually exists outside the cabin without leaving the cabin.

[0046] In one embodiment, the controller may first identify the odor source in the external space, and then determine the second aroma associated with the odor source. The odor source described in the embodiment of the present application is any object in the external space that can emit aromas. It is understandable that the second aroma determined in this way is an aroma that should theoretically exist in the external space, that is, the identified odor source will theoretically emit the second aroma. This solution can form the above-mentioned expected odor in the cabin by controlling the fragrance system to release the second aroma in the cabin, thereby creating an olfactory atmosphere corresponding to the odor in the cabin.

[0047] In one embodiment, the controller can use image recognition technology to identify the odor source. As mentioned above, the vehicle can be equipped with an image acquisition device such as a camera, so that the controller can obtain the environmental image of the external space captured by the image acquisition device, and identify the odor source in the external space based on the environmental image. In this way, the controller can use image recognition technology to identify the odor source within the field of view of the vehicle (actually the image acquisition device), and determine its associated fragrance as the second fragrance, so that by controlling the fragrance system to release the second fragrance, the olfactory atmosphere corresponding to the odor source can be created in the cabin, presenting a "visible and audible" olfactory effect for the occupants.

[0048] The controller may locally run the odor source identification logic to identify the odor sources around the vehicle; or the controller may upload the environmental image captured by the image acquisition device to the server, so that the server can run the odor source identification logic to identify the odor sources around the vehicle.

[0049] The odor source identification logic may be based on the identification logic of the odor source identification model or the screening logic based on image similarity. Exemplarily, in the identification logic based on the odor source identification model, the environmental image may be input into the pre-trained odor source identification model, and the odor source identification result output by the model after inference calculation based on the environmental image is obtained. This method has high recognition accuracy and high efficiency (such as the model can process multiple environmental images in parallel). In the screening logic based on image similarity, the image similarity between the environmental image and each standard odor source image may be calculated, or the content similarity between each image content (such as trees, flowers, etc.) in the environmental image and the standard odor source content intercepted from the standard odor source image may be calculated, and then the standard odor source image with the highest image similarity or the standard odor source content with the highest content similarity is used as the screening result, and then the odor source represented by the screening result is determined as the odor source identified from the environmental image. The above-mentioned image similarity and content similarity can adopt parameters such as PSNR (Peak Signal-to-Noise Ratio), SSIM (Structural Similarity), MSE (Mean Squared Error), cosine similarity, hash similarity, MD5 (MD5 Message-Digest Algorithm), histogram, mutual information, pixel matching, etc., and the embodiments of the present application are not limited to this. This method has a faster recognition speed, which helps to achieve fast or even real-time control of odor.

[0050] In one embodiment, for the identified odor source, the controller can query the second aroma associated with the odor source based on a pre-created object odor relationship table, wherein the object odor relationship table can record the association between at least one odor source and the aroma it releases. Based on this, the controller can use the aroma associated with the odor source queried from the object odor relationship table as the second aroma; that is, after identifying the odor source, the controller can query the aroma associated with the odor source in the above-mentioned object odor relationship table and use it as the second aroma. In this way, the controller can quickly and accurately find the second aroma corresponding to the odor source based on the pre-created object odor relationship table.

[0051] Wherein, one odor source in the object odor relationship table may correspond to one or more aromatic substances. Exemplarily, the object odor relationship table can be shown in Table 1 below.

[0052] Table 1

[0053] Odor source Aroma Osmanthus / Osmanthus tree Linalool, Linalool Oxide, β-Ionone Pine Tree / Pine Needles Pinene, longifolene, camphene, elemene, limonene Grass / lawn mower Chlorophyll, Chlorophyll BBQ / BBQ stall Dimethyl disulfide, dimethyl trisulfide, mercaptan, thiophene

[0054] It is worth noting that, in the case where any odor source corresponds to multiple aromas, the above-mentioned object odor relationship table can also record the concentration ratio of various aromas (specifically, it can be volume ratio, weight ratio, etc.), so that the controller can simultaneously determine the release concentration of various aromas. For example, for the two aromas corresponding to the green grass in Table 1 above, the table can also record that the proportion of green leaf alcohol is 60%, the proportion of green leaf aldehyde is 40, etc. Of course, the concentration ratio of various aromas corresponding to each odor source can be obtained through precision instrument detection, such as obtaining from an authoritative detection agency, etc., and the embodiments of the present application are not limited to this.

[0055] Step 304 : Control the fragrance system to release target fragrance into the cabin of the vehicle, wherein the target fragrance includes the external fragrance and / or similar fragrance having a similar smell to the external fragrance.

[0056] After determining the external aroma in the external space, the fragrance system can be controlled to release the target aroma (specifically the external aroma and / or its similar aroma) to emit a corresponding smell (hereinafter referred to as the target smell) in the cabin. Because the aromas that can be released by the fragrance system (hereinafter referred to as the alternative aromas) are often pre-stored, and the external aromas are determined by the location of the vehicle and its surrounding environment, for any external aroma determined, the external aroma may or may not exist in the alternative aromas stored in the fragrance system. In this regard, when the fragrance system stores any external aroma, the fragrance system can be controlled to release the external aroma; and when the fragrance system does not store any external aroma, a similar aroma to the external aroma is determined from the alternative aromas stored in the fragrance system, and the fragrance system is controlled to release the similar aroma. In other words, after determining each external aroma, the controller can query whether the external aroma is included in all the candidate aromas stored in the fragrance system for each external aroma: if it is included, the fragrance is controlled to be released in the cabin; if it is not included, a similar aroma to the external aroma can be further determined from the candidate aromas: if a similar aroma is determined, the similar aroma is controlled to be released in the cabin. Of course, if a similar aroma is not determined, the external aroma and its similar aromas may not be released, and only the queried / determined external aromas and / or their similar aromas may be released. In this way, the fragrance system can be controlled to release external aromas first, so as to form a target smell that is the same as the external smell in the cabin as much as possible; and when the fragrance system does not store external aromas, similar aromas that are close to the external aromas are determined from the stored candidate aromas and controlled to be released, so as to form a target smell that is close to the external smell in the cabin.

[0057] It is understandable that, when the target aroma includes the first aroma, the target odor formed in the cabin is the same as or similar to the actual odor in the external space; and when the target aroma includes the second aroma, the target odor formed in the cabin is the same as or similar to the expected odor that the odor source in the external space will theoretically release. Of course, given that different passengers often have different current physical conditions, olfactory sensitivities, and odor perceptions, when passengers actually smell the released target aroma, the odors they personally experience may not be completely consistent, and the embodiments of the present application are not limited to this.

[0058] As can be seen from the above embodiments, in this solution, the controller installed in the vehicle determines the first aroma actually contained in the air outside the vehicle and / or the second aroma expected to be contained, and then controls the fragrance system to release the above aroma or similar aroma close to its smell to emit the smell corresponding to the external aroma in the cabin. It can be seen that this solution can flexibly adjust the smell in the cabin according to the actual environment around the vehicle through the cooperation between the controller and the fragrance system, thereby achieving the smell following effect that the smell in the cabin changes with the changes in the surrounding environment of the vehicle (for example, when the vehicle is parked next to an osmanthus tree with osmanthus flowers, the cabin will be full of osmanthus fragrance; and when the vehicle is driving on a grassland / grass with green grass, the cabin will be full of grass smell, etc.), creating an olfactory environment in the cabin that is the same (or close) as the space outside the cabin. Obviously, compared with the relevant technology, this solution can be applied to scenes where it is not suitable to open the window or turn on the external circulation function (such as raining / snowing outside the car, poor air quality outside the car, etc.), and the olfactory experience of the occupants in the cabin can be enriched without the occupants opening the window, thereby improving their riding experience.

[0059] In one embodiment, when the controller controls the fragrance system to release the target fragrance, it can first determine the release parameters of the target fragrance, and the release parameters include at least the release concentration and the release duration; then control the fragrance system to release the target fragrance into the cabin of the vehicle according to the release parameters. Among them, the release concentration shown can include the concentration ratio of different fragrances, the release amount ratio, and / or the concentration value of each fragrance. Of course, considering that the fragrances released by the fragrance system are usually contained (or sealed) in fragrance capsules, fragrance bottles / boxes and other containers according to a certain concentration, that is, the concentration value of the fragrance is a preset fixed value, it is also possible to only ensure the concentration ratio and / or release amount ratio of various fragrances. The release duration can be the duration of the release process, or it can also be the single release duration and the interval between each release, etc., which will not be repeated. It can be understood that by controlling the fragrance system to release the target fragrance in strict accordance with the above-mentioned release concentration and release duration, precise control of the fragrance release amount is achieved, which helps to ensure that the target smell formed by the released fragrance in the cabin is as close as possible to the aforementioned actual smell and / or expected smell, thereby creating a more realistic olfactory experience in the cabin (i.e., the degree of smell simulation is higher).

[0060] In addition, in addition to the release concentration and release duration, the release parameters may also include whether to heat before release, (if heated) the heating temperature, the release mode (spray, evaporation, etc.), the release channel (when the fragrance system includes multiple channels located at different positions in the cabin), etc., which will not be repeated here.

[0061] Among them, for a variety of specific application scenarios, a variety of methods (i.e., at least one of the following) can be used to determine the release parameters of the target aroma. For example, the controller can obtain the weather information of the external space and determine the release parameters of the target aroma based on the weather information. Exemplarily, the weather information may include but is not limited to information such as temperature, humidity, wind speed, and wind direction. Exemplarily, it may be assumed that the odor source is an osmanthus tree and the target aroma is the above-mentioned various aromas that form the osmanthus fragrance. Taking the temperature weather information as an example, given that the higher the temperature within a certain temperature range, the stronger the osmanthus fragrance tends to be, the higher the current temperature outside the vehicle is determined, the higher the release concentration of the above-mentioned various aromas can be set and the longer the release time. Of course, the change curve of the weather information of each release parameter of each fragrance of the aroma in the actual scene can be obtained from an authoritative agency to ensure that the determined release parameters conform to the actual laws and improve the accuracy of the parameters.

[0062] For another example, the distance from the odor source to the vehicle can also be determined, and the release parameters of the target aroma can be determined based on the distance. For example, since the concentration of aroma tends to gradually decrease with increasing distance (i.e., the farther from the odor source, the weaker the odor), the release concentration of the target aroma can be determined according to the rule that it is negatively correlated with the distance. This method can create a simulated effect for users in the cabin that "the farther from the odor source, the weaker the odor you smell."

[0063] For another example, the odor preference information of the occupants in the cabin can also be determined, and the release parameters of the target aroma can be determined based on the odor preference information, so that the released target aroma creates a realistic olfactory atmosphere in the cabin, making the atmosphere more in line with the personal preferences of the occupants.

[0064] For example, if it is determined based on the historical adjustment record of the current occupant U1 on the fragrance system that the occupant prefers a fragrance with a strong smell, it can be determined that the release concentration of the target fragrance is higher; conversely, if the occupant U2 prefers a fragrance with a light smell, it can be determined that the release concentration of the target fragrance is lower. Of course, if the odor preferences of different occupants in the cabin are different, the release parameters can be determined according to the odor preference of one of the occupants (such as a driver or a child, etc.), or the sub-release parameters can be determined separately according to the odor preferences of multiple occupants, and the average value (such as arithmetic mean or weighted average, etc.) of each sub-release parameter is determined as the release parameter of the target fragrance, and the fragrance system is controlled to release the target fragrance according to the parameter, which will not be repeated. In one embodiment, after the fragrance system releases the target fragrance, the occupants in the cabin may have a need to adjust the smell after smelling the corresponding target odor, such as feeling that the odor is too strong or not refreshing enough. At this time, the occupant can issue a smell adjustment instruction to the vehicle (the instruction is ultimately responded to by the controller) by performing specific actions (such as touch screen operation, voice and / or gesture, etc.), wherein the degree of the above-mentioned behavior (such as the sliding distance of the touch screen operation) or content (the voice content of the voice instruction) can be used to characterize the direction and length of the adjustment. Based on this, the controller can adjust the release parameters of the target fragrance in response to the smell adjustment instruction, and control the fragrance system to release the target fragrance into the cabin according to the adjusted release parameters, so as to adjust the smell in the cabin according to the user's wishes. In this way, the occupant can flexibly adjust the smell in the cabin according to his own feelings and wishes to better meet his olfactory needs.
