Description

Technical Field

[0001] This invention relates to the field of intelligent cockpit technology, and in particular to a personalized fragrance adjustment method and system based on intelligent driving scenarios. Background Technology

[0002] With the development of autonomous driving technology and vehicle-to-everything (V2X) connectivity, the interior environment of automobiles is receiving increasing attention. Existing in-car fragrance systems typically only support manual switching or scenario-based triggering, lacking the ability to dynamically adjust based on user emotions, driving status, or the external environment. During driving, vision and hearing are often focused on road conditions, making it difficult to be distracted by more information. Smell, accounting for 3.5% of information acquisition, often remains relatively unchanged in daily driving. Therefore, using fragrance to stimulate the sense of smell as an information output method, supplementing the vehicle's notification system, can reduce the distraction of vision and hearing while driving, improving driving safety. While there are methods that actively identify and release corresponding fragrances based on the emotions of occupants in the cabin, existing methods do not consider the safety applications of fragrance and lack prioritization when multiple fragrance requests exist, potentially leading to overlooking important factors. Therefore, there is an urgent need for personalized fragrance adjustment methods and systems based on intelligent driving scenarios to address the existing technical problems. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art, and proposes a personalized fragrance adjustment method and system based on intelligent driving scenarios.

[0004] In a first aspect, embodiments of the present invention provide a personalized fragrance adjustment method based on intelligent driving scenarios, comprising:

[0005] The vehicle driving status is obtained, including parking status, normal driving status, and abnormal driving status.

[0006] The system acquires the physiological and psychological states of the occupants and the driving environment, and adjusts the personalized fragrance based on the vehicle's driving status.

[0007] Furthermore, the physiological and psychological states of the occupants and the driving environment are obtained, and the personalized fragrance is adjusted based on the vehicle's driving state. Specific methods include:

[0008] When the vehicle is in a parked state, the physiological state of the occupants and the overall atmosphere are obtained, and the corresponding type of fragrance is controlled to operate according to the physiological state of the occupants and the overall atmosphere.

[0009] When the vehicle is in normal driving condition, the driver's mood state, driving environment state and driver's physiological state are obtained, and the corresponding type of fragrance is controlled to operate according to the driver's mood state, driving environment state and driver's physiological state respectively.

[0010] When the vehicle is in an abnormal driving state, the driver's physiological and psychological states are obtained, and the corresponding type of fragrance is controlled to operate according to the driver's physiological and psychological states respectively.

[0011] Furthermore, when the vehicle is in a parked state, the corresponding type of fragrance is controlled to operate based on the physiological state of the occupants and the overall atmosphere. Specific steps include:

[0012] The system monitors the physiological signals of passengers inside the vehicle using in-vehicle sensors to determine if they are experiencing motion sickness. If a passenger is experiencing motion sickness, the system activates a fragrance that helps alleviate it.

[0013] If the passenger is not experiencing motion sickness, the in-vehicle sensors monitor the overall atmosphere inside the vehicle and determine if the current atmosphere is negative. If the atmosphere is negative, a calming fragrance is activated.

[0014] If the overall atmosphere inside the vehicle is not negative, the vehicle's sensors monitor the passengers' physiological signals to determine if they are drowsy. If they are drowsy, the system activates a fragrance with sleep-inducing effects; if they are not drowsy, the system activates a fragrance with uplifting effects.

[0015] Furthermore, the overall atmosphere of the occupants inside the vehicle is monitored by in-vehicle sensors to determine whether the current overall atmosphere is negative. Specific methods include: monitoring the facial expressions, tone of voice, and breathing rate of the occupants inside the vehicle using in-vehicle cameras and microphones to determine the current emotions of each occupant. The occupant emotions include at least normal, anxious, angry, surprised, fearful, happy, sad, and motion sickness; assigning a value to each emotion; and calculating a total score to obtain the overall atmosphere of the cabin when there are multiple occupants with different expressions.

[0016] Furthermore, if the overall atmosphere of the occupants is negative, the vehicle's infotainment system can play soothing playlists and activate seat massage to enhance the driver's comfort, while gentle cabin voice prompts can also improve the driver's mood.

[0017] Furthermore, when the vehicle is in normal driving condition, the corresponding type of fragrance is controlled to operate based on the driver's mood, driving environment, and driver's physiological state. Specific steps include:

[0018] The system monitors the mood of passengers inside the vehicle using in-vehicle sensors to determine if they are experiencing any of the following emotions: anxiety, anger, surprise, or fear. If a passenger is experiencing any of these emotions, the system activates a calming fragrance. If a passenger is drowsy, the system activates a sobering fragrance.

[0019] If the occupants are in a happy mood, continue to monitor the current driving environment. If the current driving environment is that the road and vehicle conditions are normal but danger is foreseeable ahead, then activate the fragrance with a warning function. If the current driving environment is that there is a persistent high risk, then activate the fragrance with a focus function.

[0020] If the current driving environment is suitable for driving, continue to determine whether the passengers in the vehicle are experiencing motion sickness. If the passengers are experiencing motion sickness, then turn on the fragrance that relieves motion sickness.

[0021] If the passengers in the car are not experiencing motion sickness, determine whether the overall atmosphere among the passengers is negative. If the overall atmosphere is negative, turn on a fragrance with a calming effect; if the overall atmosphere is positive, turn on a fragrance with a cheerful effect.

[0022] Furthermore, when the vehicle is in an abnormal driving state, the corresponding type of fragrance is controlled to operate based on the physiological state of the occupants and the overall atmosphere. Specific steps include:

[0023] When the vehicle is in an abnormal driving state, the vehicle uses in-vehicle sensors to obtain the emotional state of the occupants and determine whether their emotions are stable. If the occupants are emotionally unstable, it is determined that the driver is driving dangerously due to emotional instability. At this time, the vehicle takes over the driving and pulls over to the side of the road and alarms when the surroundings are confirmed to be safe. If the driver is emotionally stable, it is determined that the driver is driving dangerously due to sudden external factors, and a calming fragrance is activated.

[0024] Secondly, embodiments of the present invention also disclose a personalized fragrance adjustment system based on intelligent driving scenarios, comprising: a vehicle driving status acquisition unit and a fragrance adjustment unit; wherein:

[0025] A vehicle driving status acquisition unit is used to acquire the vehicle driving status, which includes parking status, normal driving status and abnormal driving status.

[0026] The fragrance adjustment unit is used to acquire the physiological and psychological states of the occupants and the driving environment, and adjust the personalized fragrance based on the vehicle's driving state.

[0027] The fragrance adjustment unit is used to acquire the physiological and psychological states of the occupants and the driving environment, and adjusts the personalized fragrance based on the vehicle's driving state. Specific methods include:

[0028] When the vehicle is in a parked state, the physiological state of the occupants and the overall atmosphere are obtained, and the corresponding type of fragrance is controlled to operate according to the physiological state of the occupants and the overall atmosphere.

[0029] When the vehicle is in normal driving condition, the driver's mood state, driving environment state and driver's physiological state are obtained, and the corresponding type of fragrance is controlled to operate according to the driver's mood state, driving environment state and driver's physiological state respectively.

[0030] When the vehicle is in an abnormal driving state, the driver's physiological and psychological states are obtained, and the corresponding type of fragrance is controlled to operate according to the driver's physiological and psychological states respectively.

[0031] Furthermore, when the vehicle is in a parked state, the corresponding type of fragrance is controlled to operate based on the physiological state of the occupants and the overall atmosphere. Specific steps include:

[0032] The system monitors the physiological signals of passengers inside the vehicle using in-vehicle sensors to determine if they are experiencing motion sickness. If a passenger is experiencing motion sickness, the system activates a fragrance that helps alleviate it.

[0033] If the passenger is not experiencing motion sickness, the in-vehicle sensors monitor the overall atmosphere inside the vehicle and determine if the current atmosphere is negative. If the atmosphere is negative, a calming fragrance is activated.

[0034] If the overall atmosphere inside the vehicle is not negative, the vehicle's sensors monitor the passengers' physiological signals to determine if they are drowsy. If they are drowsy, the system activates a fragrance with sleep-inducing effects; if they are not drowsy, the system activates a fragrance with uplifting effects.

[0035] Thirdly, embodiments of the present invention also disclose an electronic device, comprising:

[0036] One or more processors;

[0037] Memory, used to store one or more programs;

[0038] When the one or more programs are executed by the one or more processors, the one or more processors implement the fragrance adjustment method.

[0039] Fourthly, embodiments of the present invention also disclose a computer-readable medium storing a computer program, characterized in that the computer program, when executed by a processor, implements the steps in the fragrance adjustment method.

[0040] This invention provides a personalized fragrance adjustment method based on intelligent driving scenarios. It acquires the vehicle's driving status, including stopped, normal driving, and abnormal driving states; it also acquires the physiological and psychological states of the occupants and the driving environment. Based on these driving states, the personalized fragrance is adjusted. This invention comprehensively assesses the current state of the vehicle and driver by considering the cabin conditions and the external environment. The fragrance helps regulate the mood of the occupants and serves to alert, calm, and soothe them, making the driving process safer and more comfortable. Attached Figure Description

[0045] To enable those skilled in the art to better understand the technical solutions of the present invention, exemplary embodiments of the present invention are described below in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to aid understanding. These should be considered merely exemplary. Therefore, those skilled in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0046] Where there is no conflict, the various embodiments of the present invention and the features thereof may be combined with each other.

[0047] As used herein, the term “and / or” includes any and all combinations of one or more related enumerated entries.

[0048] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. As used herein, the singular forms “a” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that when the terms “comprising” and / or “made of” are used in this specification, the presence of the stated feature, integral, step, operation, element, and / or component is specified, but the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or groups thereof is not excluded.

[0049] Unless otherwise specified, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art. It will also be understood that terms such as those defined in commonly used dictionaries should be interpreted as having the meaning consistent with their meaning in the context of the relevant art and the invention, and will not be interpreted as having an idealized or overly formal meaning unless expressly so defined herein.

[0050] In the technical solution of this invention, the collection, storage, use, processing, transmission, provision, and disclosure of user personal information all comply with relevant laws and regulations and do not violate public order and good morals. The use of user data in this technical solution follows relevant national laws and regulations (e.g., the "Information Security Technology - Personal Information Security Specification").

[0051] To address at least one of the technical problems existing in the aforementioned related technologies, the present invention provides a personalized fragrance adjustment method and system based on intelligent driving scenarios.

[0052] This invention provides a personalized fragrance adjustment method based on intelligent driving scenarios, such as... Figure 1 ,include:

[0053] S100. Obtain the vehicle driving status, which includes parking status, normal driving status and abnormal driving status;

[0054] Specifically, vehicle driving data such as speed, acceleration, and tilt angle are acquired through the backend to determine the vehicle's driving status. This status includes stopped, normal driving, and abnormal driving states. Abnormal driving states include excessive speed, rapid braking / starting, and sharp turns. The data is transmitted to the backend via an onboard T-Box (Telematics Box) at a certain frequency (e.g., 10Hz). More meaningful features are extracted from the raw data, such as: calculating the derivative of acceleration (jerk), i.e., the rate of change of acceleration, to identify rapid acceleration or deceleration; calculating the duration and trend of tilt angle to assess stability during turns or uphill / downhill driving; and statistically analyzing the speed variance over a period of time to assess driving smoothness.

[0055] The vehicle status is determined based on features and preset thresholds. Common vehicle statuses and determination conditions include:

[0056] Stationary state: speed close to 0 (e.g., less than 0.5 km / h) and maintained for a period of time (e.g., 5 seconds).

[0057] Acceleration state: longitudinal acceleration is greater than the threshold (e.g., 0.3 m / s²).

[0058] Deceleration state: longitudinal acceleration is less than the threshold (e.g., -0.3m / s²).

[0059] Uniform state: The rate of change of velocity is small and the acceleration is close to 0.

[0060] Turning state: The absolute value of lateral acceleration is greater than the threshold (e.g., 0.5 m / s²) or the absolute value of roll angle is greater than the threshold (e.g., 10 degrees) and this condition persists for a certain period of time.

[0061] Uphill / Downhill status: The pitch angle is consistently greater than the uphill threshold (e.g., 5 degrees) or less than the downhill threshold (e.g., -5 degrees).

[0062] Emergency braking state: longitudinal acceleration is less than the emergency braking threshold (e.g., -0.6 m / s²).

[0063] Rollover risk status: The absolute value of the roll angle exceeds the danger threshold (e.g., 25 degrees).

[0064] The vehicle's driving status is obtained through the above vehicle status.

[0065] S200. Obtain the physiological and psychological states of the occupants and the driving environment, and adjust the personalized fragrance based on the vehicle's driving state.

[0066] In this embodiment, as Figure 2 Based on the physiological state of the occupants and the overall atmosphere, the corresponding type of fragrance is controlled to operate, specifically including:

[0067] S201. When the vehicle is in a parked state, the physiological state of the occupants and the overall atmosphere are obtained, and the corresponding type of fragrance is controlled to operate according to the physiological state of the occupants and the overall atmosphere.

[0068] S202. When the vehicle is in normal driving condition, obtain the driver's mood state, driving environment state and driver's physiological state, and control the operation of the corresponding type of fragrance according to the driver's mood state, driving environment state and driver's physiological state respectively;

[0069] S203. When the vehicle is in an abnormal driving state, the driver's physiological and psychological states are obtained, and the corresponding type of fragrance is controlled to operate according to the driver's physiological and psychological states respectively. In this embodiment, the order of steps S201, S202, and S203 is not limited.

[0070] Specifically, this embodiment provides a set of fragrance combinations that can meet the needs of specific scenarios.

[0071] 1. Calming Fragrances: Fragrances with citrus, floral, and woody notes, such as lavender, chamomile, bergamot, and cedar, use soft, soothing, and refreshing scents to relieve tension and reduce negative emotions.

[0072] 2. Alert / Warning Fragrances: Fragrances with a blend of citrus and green notes, such as bergamot and mint, use fresh and spicy scents to help users perceive changes in smell more quickly and serve as a warning.

[0073] 3. Focus on Fragrance: Fragrances with floral, green, and woody notes, such as lavender, cedar, and grass, combined with calming and soothing scents to help users concentrate while driving.

[0074] 4. Soothing Fragrances: Fragrances that primarily blend fougère, woody, and floral notes, such as lavender, chamomile, sandalwood, and green tea, use gentle scents to soothe emotions and calm the user.

[0075] 5. Motion Sickness Relief Fragrances: Fragrances with citrus, green, and oriental notes, such as bergamot, mint, eucalyptus, patchouli oil, and perilla leaf oil, can relieve motion sickness through their strong, stimulating scents.

[0076] 6. Joyful Fragrances: Fragrances with floral and fruity notes, such as rose and tea, create a happy and carefree atmosphere through rich floral and fruity aromas.

[0077] 7. Sleep-aiding fragrances: Fragrances with floral and woody notes, such as rosemary, chamomile, vanilla, and cedarwood, provide a sleep-inducing effect through their soft and soothing scents.

[0078] In some preferred embodiments, when the vehicle is in a parked state, the operation of corresponding types of fragrances is controlled according to the physiological state of the occupants and the overall atmosphere. Specific steps include:

[0079] The system monitors the physiological signals of passengers inside the vehicle using in-vehicle sensors to determine if they are experiencing motion sickness. If a passenger is experiencing motion sickness, the system activates a fragrance that helps alleviate it.

[0080] If the occupants are not experiencing motion sickness, the overall atmosphere inside the vehicle is monitored by in-vehicle sensors to determine if it is negative. If it is, a calming fragrance is activated. The method for monitoring the overall atmosphere using in-vehicle sensors to determine if it is negative includes: monitoring the occupants' facial expressions, tone of voice, and breathing rate using an in-vehicle camera and microphone to determine the current emotions of each occupant. These emotions include at least normal, anxious, angry, surprised, fearful, happy, sad, and motion sickness. Each emotion is assigned a value. When multiple occupants with different expressions are present, a total score is calculated to obtain the overall atmosphere inside the cabin.

[0081] For example, assign scores to facial expressions: anger = -3, fear = -2, sadness = -2, anxiety = -1, surprise = -1, motion sickness = 0, normal = 0, drowsiness = 0, happiness = 1. Multiply the adult score by 2 and the child score by 1; calculate the total score to obtain the overall emotional atmosphere inside the cabin.

[0082] In some preferred embodiments, if the overall atmosphere of the occupants in the vehicle is negative, the vehicle system can be used to play soothing playlists and activate seat massage to improve the driver's comfort, and gentle cabin voice prompts can be used to improve the driver's mood.

[0083] If the overall atmosphere inside the vehicle is not negative, the vehicle's sensors monitor the passengers' physiological signals to determine if they are drowsy. If they are drowsy, the system activates a fragrance with sleep-inducing effects; if they are not drowsy, the system activates a fragrance with uplifting effects.

[0084] In some preferred embodiments, when the vehicle is in normal driving condition, the operation of corresponding types of fragrances is controlled according to the driver's mood, driving environment, and driver's physiological state. Specific steps include:

[0085] The system monitors the mood of passengers inside the vehicle using in-vehicle sensors to determine if they are experiencing any of the following emotions: anxiety, anger, surprise, or fear. If a passenger is experiencing any of these emotions, the system activates a calming fragrance. If a passenger is drowsy, the system activates a sobering fragrance.

[0086] If the occupants are in a happy mood, continue to monitor the current driving environment. If the current driving environment is that the road and vehicle conditions are normal but danger is foreseeable ahead, then activate the fragrance with a warning function. If the current driving environment is that there is a persistent high risk, then activate the fragrance with a focus function.

[0087] If the current driving environment is suitable for driving, continue to determine whether the passengers in the vehicle are experiencing motion sickness. If the passengers are experiencing motion sickness, then turn on the fragrance that relieves motion sickness.

[0088] If the passengers in the car are not experiencing motion sickness, determine whether the overall atmosphere among the passengers is negative. If the overall atmosphere is negative, turn on a fragrance with a calming effect; if the overall atmosphere is positive, turn on a fragrance with a cheerful effect.

[0089] In some preferred embodiments, when the vehicle is in an abnormal driving state, the operation of corresponding types of fragrances is controlled according to the physiological state of the occupants and the overall atmosphere. Specific steps include:

[0090] When the vehicle is in an abnormal driving state, the vehicle uses in-vehicle sensors to obtain the emotional state of the occupants and determine whether their emotions are stable. If the occupants are emotionally unstable, it is determined that the driver is driving dangerously due to emotional instability. At this time, the vehicle takes over the driving and pulls over to the side of the road and alarms when the surroundings are confirmed to be safe. If the driver is emotionally stable, it is determined that the driver is driving dangerously due to sudden external factors, and a calming fragrance is activated.

[0091] In some preferred embodiments, several diffusers can be provided for the in-vehicle fragrance device. Each diffuser has a corresponding fragrance base. Each fragrance base has an adjustable concentration level, and the release amount can be precisely controlled by an electronic pump to adjust the fragrance concentration in real time. When a scene is executed, a suitable fragrance is selected from a preset scene-fragrance mapping table based on the scene recognition result, and released at a specified concentration.

[0092] Furthermore, each diffuser can be paired with a different type of fragrance base essential oil. When executing a scene, based on the scene recognition results, a suitable fragrance combination is selected from a preset scene-fragrance mapping table to release different base fragrances at a specified concentration, mixing to achieve the specified complex fragrance notes.

[0093] Furthermore, depending on the purpose and type of fragrance, different types of materials can be used. For example, woody and oriental base notes can be achieved using heated liquid diffusers, while citrus and green notes, which serve a warning function, can be achieved using a misting and evaporating fragrance system to deliver their effects in a shorter time.

[0094] This embodiment provides a personalized fragrance adjustment method based on intelligent driving scenarios. It acquires the vehicle's driving status, including stopped, normal driving, and abnormal driving states; it also acquires the physiological and psychological states of the occupants and the driving environment. Based on these driving states, the personalized fragrance is adjusted. This invention comprehensively assesses the vehicle and driver's current condition by considering the cabin environment and external conditions. The fragrance helps regulate the occupants' moods and provides warning, calming, and soothing effects, making the driving process safer and more comfortable.

[0097] The fragrance adjustment unit is used to acquire the physiological and psychological states of the occupants and the driving environment, and adjust the personalized fragrance based on the vehicle's driving state.

[0098] In some preferred embodiments, the fragrance adjustment unit is used to acquire the physiological state, psychological state, and driving environment state of the occupants in the vehicle, and adjust the personalized fragrance based on the vehicle's driving state. Specific methods include:

[0099] When the vehicle is in a parked state, the physiological state of the occupants and the overall atmosphere are obtained, and the corresponding type of fragrance is controlled to operate according to the physiological state of the occupants and the overall atmosphere.

[0100] When the vehicle is in normal driving condition, the driver's mood state, driving environment state and driver's physiological state are obtained, and the corresponding type of fragrance is controlled to operate according to the driver's mood state, driving environment state and driver's physiological state respectively.

[0101] When the vehicle is in an abnormal driving state, the driver's physiological and psychological states are obtained, and the corresponding type of fragrance is controlled to operate according to the driver's physiological and psychological states respectively.

[0102] In some preferred embodiments, when the vehicle is in a parked state, the operation of corresponding types of fragrances is controlled according to the physiological state of the occupants and the overall atmosphere. Specific steps include:

[0103] The system monitors the physiological signals of passengers inside the vehicle using in-vehicle sensors to determine if they are experiencing motion sickness. If a passenger is experiencing motion sickness, the system activates a fragrance that helps alleviate it.

[0104] If the passenger is not experiencing motion sickness, the in-vehicle sensors monitor the overall atmosphere inside the vehicle and determine if the current atmosphere is negative. If the atmosphere is negative, a calming fragrance is activated.

[0105] If the overall atmosphere inside the vehicle is not negative, the vehicle's sensors monitor the passengers' physiological signals to determine if they are drowsy. If they are drowsy, the system activates a fragrance with sleep-inducing effects; if they are not drowsy, the system activates a fragrance with uplifting effects.
