[0079] Figure 4 A scenario type of a scent releasing method according to exemplary embodiments of the present application is schematically illustrated.

[0080] The scenario type can optionally comprise a welcome scenario identified in response to detecting that a user opens a door of a vehicle to enter the vehicle. For example, by means of a door sensor 31 and / or a camera 32, it can be detected that a user opens a door of a vehicle to enter the vehicle. The control device 2 is communicatively connected to the door sensor 31 and / or the camera 32, so as to acquire feature information characterizing a door state and a user action. Based on the acquired feature information, the control device 2 can identify that a current scenario type is a welcome scenario. The control device 2 can generate an adjustment instruction according to the welcome scenario, and send the adjustment instruction to the scent releasing device 1.

[0081] The correspondence between the scenario type and the scent can be stored, for example, in the control device 2. The adjustment instruction can contain kind information of the scent. In particular, the adjustment instruction can contain recipe information. The recipe information can comprise kind information and proportion information of a plurality of scents. Optionally, the scent releasing device 1 releases a scent corresponding to the welcome scenario in response to the adjustment instruction.

[0082] Optionally, the correspondence between the scenario type and the scent can be stored in the scent releasing device 1. The adjustment instruction can contain scenario type information. The scent releasing device 1 reads kind and / or proportion information of a scent corresponding to the scenario type in response to the adjustment instruction.

[0083] Optionally, the smell corresponding to the greeting scenario is associated with the user entering the vehicle. For example, the user can pre-set his / her preferred smell. In the case of identifying the greeting scenario, the control device 2 can further identify the identity information of the user entering the vehicle in the greeting scenario. For example, the identity of the user can be identified based on the image containing the user taken by the camera 32 through image recognition technology. According to the identity information of the user, the pre-set preferred smell information can be read. The control device 2 can make the smell releasing device 1 release the smell preferred by the user through the adjustment instruction. When the user travels a long distance or commutes by the vehicle, the user can be greeted by the personalized fragrance as soon as he / she enters the vehicle. This is particularly advantageous for improving the user experience.

[0084] As an example, in response to the greeting scenario, the release port 13 integrated in the A-pillar can be selected to release the smell corresponding to the greeting scenario.

[0085] Figure 5 A scenario type of the fragrance releasing method according to the exemplary embodiments of the present application is schematically shown.

[0086] The scenario type can optionally include identifying a destination scenario in response to the user operating the navigation device 4 of the vehicle to navigate to a destination in a navigation operation. The control device 2 is communicatively connected to the navigation device 4 to obtain user operation information about the operation of the user on the navigation device 4. In turn, the control device 2 can identify that the current scenario type is the destination scenario based on the user operation information. The control device 2 can generate an adjustment instruction according to the destination scenario and send the adjustment instruction to the smell releasing device 1.

[0087] Optionally, the smell corresponding to the destination scenario is associated with the destination.

[0088] In particular, the smell associated with the destination can correspond to the brand information of the destination. For example, when the destination is a store or an activity site of a certain brand, the corresponding smell can be set as the associated fragrance of the brand. If the user drives the vehicle to the store of a certain brand for shopping, the in-vehicle fragrance system can provide the fragrance associated with the brand before the user arrives at the destination, so that the user can feel the atmosphere of the brand in advance. This helps to improve the user experience on the one hand, and on the other hand, it is advantageous to enhance the user's impression of the brand.

[0089] Figure 6 A scenario type of the fragrance releasing method according to the exemplary embodiments of the present application is schematically shown.

[0090] The scenario type can optionally include identifying a game scenario in response to the user playing a game in a game operation.

[0091] In an exemplary embodiment, a user can play a game by using an in-vehicle device. For example, a user can play a game on a display screen of a vehicle. Alternatively, a vehicle can be installed with a holographic projection device, which can project a game screen in front of a user, and recognize the user's operation through image recognition technology. In a further embodiment, a user can also play a game by using a mobile terminal device, such as a mobile phone. By means of a camera 32 of a vehicle, a game screen presented on a mobile phone and the user's operation can be captured.

[0092] The odor corresponding to the game scene is optionally associated with the content of the game operation. For example, if a user is playing a "fruit ninja" game, the odor released can be related to the fruit in the game, such as the odor of apples, watermelons and / or lemons being released accordingly.

[0093] In an exemplary embodiment according to the present application, the scene type can include a music scene identified in response to a music playing operation of a music playing device of a vehicle. The odor corresponding to the music scene is optionally associated with the style of music played by the music playing device.

[0094] The style information of music can be provided by the music playing device. Alternatively, the recognition device can determine the style of the played music according to the timbre characteristics, rhythm characteristics, pitch characteristics, lyrics characteristics, creator characteristics of the played music.

[0095] In an exemplary embodiment according to the present application, the scene type can include a drowsy driving scene identified in response to a drowsy driving operation of a user, so that the odor releasing device 1 is capable of releasing an odor corresponding to the drowsy driving scene. The odor corresponding to the drowsy driving scene can be particularly a refreshing odor, such as a mint, lemon, rosemary or eucalyptus fragrance with stimulating properties. These odors can act on the sympathetic nervous system of the human body through olfactory stimulation, helping to improve the driver's alertness, shorten the reaction time, and relieve mental fatigue and decreased attention caused by long driving.

[0096] For example, the image of the driver can be captured by means of the camera 32. By means of the head movement and / or the state of the eyes of the driver, etc., it can be detected whether the driver is performing a drowsy driving operation.

[0097] In an exemplary embodiment according to the present application, the scene type can include an energy recovery scene identified in response to the vehicle being parked and the user staying in the vehicle to rest, so that the odor releasing device 1 is capable of releasing an odor corresponding to the energy recovery scene.

[0098] Optionally, in response to identifying the energy recovery scenario, a music playing device, a light, a display screen, and / or other vehicle components of the vehicle can cooperate with the scent releasing device 1 to create an atmosphere suitable for calming, meditation, or rest. For example, the music playing device can play soothing music, and the brightness of the light can be reduced.

[0099] In an example embodiment according to the present application, the scenario type can include a health scenario identified in response to detecting a physiological discomfort feature of a user and / or a pet in the vehicle, so that the scent releasing device 1 is capable of releasing a scent of Chinese herbal medicine according to the identified health scenario.

[0100] For example, an image of the user and / or the pet in the vehicle can be captured by means of the camera 32. By identifying feature information such as the posture, movement, and / or expression of the user, it can be detected whether the user has a physiological discomfort symptom such as car sickness or a cold. In the case of identifying the health scenario, the released scent of Chinese herbal medicine helps to relieve the physiological discomfort.

[0101] Optionally, car sickness can be relieved by releasing scents of peppermint, ginger, and / or agastache.

[0102] In an example embodiment according to the present application, the control device 2 can identify the mood of the user, and control the scent releasing device 1 to release a corresponding scent according to the mood of the user.

[0103] In an example embodiment according to the present application, the control device 2 can identify a voice instruction issued by the user, and according to the identified voice instruction, control the scent releasing device 1 to release a corresponding scent.

[0104] In an example embodiment according to the present application, the control device 2 can identify the location of the vehicle, and according to the location of the vehicle, control the scent releasing device 1 to release a corresponding scent.

[0105] Figure 7 A vehicle according to an example embodiment of the present application is schematically shown. The vehicle is equipped with an in-vehicle fragrance system according to an example embodiment of the present application.

[0106] As described above, the in-vehicle fragrance system includes the scent releasing device 1. The scent releasing device 1 may, for example, have a flower shape. As an example, the scent releasing device 1 has a flower shape with 5 petals. Optionally, each petal portion is provided below with a holding cavity for holding a scent medium. Each petal portion can be used to release a different scent.

[0107] Optionally, the scent releasing device 1 can apply a non-heritage embroidery process. For example, the petal component of the scent releasing device 1 can be wrapped with an embroidery fabric.

[0108] The in-vehicle fragrance system can further comprise a display device 5. The display device 5 is configured to display information associated with the odor released by the odor releasing device 1. Through the display device 5, a visual experience corresponding to the olfactory experience can be provided.

[0109] For example, in the case where the control device 2 identifies the greeting scenario, the identity information of the user can be further identified, and the preferred odor information is read according to the identity information of the user. If the user has previously set the preferred odor as lavender fragrance, the gas releasing device can release lavender fragrance, and the display device 5 can correspondingly display image information associated with lavender, such as a lavender theme animation. Alternatively, the display device 5 can reflect the storage amount of the odor medium providing lavender through the growth state of lavender in the animation.

[0110] In this way, the user can intuitively experience the sensory linkage experience of olfaction and vision.

[0111] The display device 5 can be, for example, a central control display screen. The display device 5 can also include other in-vehicle display devices, such as a heads-up display system (HUD) and / or a Shy Tech texture smart surface, etc.

[0112] Alternatively, the in-vehicle fragrance system further comprises an odor recognition device 6. The odor recognition device 6 can be configured to recognize a non-active release odor in the vehicle that is not released by the odor releasing device 1. The display device 5 can display information associated with the non-active release odor.

[0113] Compared with the technology of identifying the user state based on images, the scheme of realizing customer interaction through odor recognition technology can more effectively protect the privacy of users. Since this technology does not involve the collection and processing of personal biological information such as images and videos, but makes identity or state judgments through the detection and analysis of odor molecules, the exposure risk of sensitive personal information is avoided, and it has a significant advantage in privacy protection.

[0114] Alternatively, the non-active release odor can include an odor introduced by the user. The odor introduced by the user can include, for example, an odor released by the user's perfume and / or beverage.

[0115] For example, if the smell recognition device 6 recognizes that the user's perfume contains a certain floral scent, such as daisy, rose, etc., the display device 5 can display information related to such flower. For example, in the case that the smell recognition device 6 recognizes that the user's perfume contains a rose scent, an image of a rose greeting the customer can be generated by a pre-trained image generation model and displayed on the display device 5. The image generation model is, for example, based on a diffusion model architecture that is capable of directly generating continuous video frames from textual prompts, which are generated based on the recognized smell. Thereby, the customer's fragrance preferences and tastes can be echoed by visual art. This helps to improve the user experience.

[0116] If the smell recognition device 6 recognizes that the user's beverage releases a coffee scent, the display device 5 can display information related to coffee. For example, an animation of a virtual digital life form (e.g. a car genie) playing in coffee beans can be generated by an image generation model and displayed on the display device 5.

[0117] Alternatively, the non-proactively released smell includes a smell generated due to an abnormal working condition of the vehicle, such as a smell caused by combustion. In this case, a warning information can be generated to remind the customer to pay attention to safety. The control device can identify the abnormal working condition based on the smell type, the concentration value, and the current working condition of the vehicle (such as vehicle speed, engine speed, brake state, etc.).

[0118] Although specific embodiments of the present application are described in detail herein, they are offered by way of illustration and for purposes of explanation only, and are not intended to limit the scope of the present application. Various substitutions, alterations and modifications can be conceived without departing from the spirit and scope of the present application.
