Description

Technical Field

[0001] The present invention belongs to the field of automobile technology, and in particular relates to a novel intelligent fragrance and emotional atmosphere control method. Background Art

[0002] With the rapid development of the connected car (IoV) and the advancement of in-vehicle equipment, cars are becoming increasingly intelligent. More and more automakers are opting for features like ambient lighting, emotion recognition, and fragrance systems. Ambient lighting can be installed on interior door panels, carpets, and other locations, allowing the driver to control its color, brightness, and other aspects. Emotion recognition requires cameras, which can be mounted on the steering wheel, rearview mirror, A-pillar, and other locations. These cameras provide prompts, such as voice greetings, when the driver's mood changes. Fragrance systems work in conjunction with the vehicle's air conditioning system. Several fragrance cartridges are installed in the vehicle, allowing the driver to freely select the fragrance type and air volume. This means that existing in-vehicle features can only operate independently and lack interoperability. Currently, car central control screens often integrate online music players, such as Kugou Music, QQ Music, and Baidu Music. These apps categorize music with specific tags. Drivers can link music tags with features like ambient lighting, emotion recognition, and fragrance systems while listening, creating an intelligent, immersive in-vehicle atmosphere system. This has become a pressing technical challenge.

[0003] A search revealed the following patent: "An In-Vehicle Intelligent Immersive Atmosphere System" (202011428009.4). This system comprises an entertainment system controller, an ambient light unit, a fragrance system, and a facial recognition controller. The facial recognition controller is connected to the entertainment system controller, which is in turn connected to the ambient light unit and the fragrance system. The facial recognition controller is used to identify the driver's emotion recognition signal and transmit it to the entertainment system controller. The entertainment system controller processes the emotion recognition signal, music tag information, and user operation behavior, and outputs ambient light control signals and fragrance system control signals to the ambient light unit and the fragrance system, respectively. The ambient light unit and the fragrance system operate accordingly. This system combines emotion recognition with in-vehicle music, ambient light, and fragrance functions to achieve intelligent control, creating an intelligent immersive atmosphere space and is suitable for widespread use. However, the aforementioned existing patents only provide corresponding control for the control unit, failing to achieve automatic learning and interactive effects. At the same time, compared to most current solutions that mechanically bind scents to scenarios, such as simply associating a vehicle's motion mode with a scent, this approach ignores dynamic environments and the user's real-time emotional changes. Current fragrance solutions often force users to passively accept preset scents, rather than generating scents based on their personal preferences. Summary of the Invention

[0004] In order to solve the above technical problems, the purpose of the present invention is to provide a new intelligent fragrance and emotional atmosphere control method.

[0005] To achieve the above object, the present invention adopts the following technical solutions: A novel intelligent fragrance and emotional atmosphere control method includes the following steps: Step 1: Monitor different input sources in the car; Step 2: Fragrance selection control, controlling the required fragrance type through information output from different input sources; Step 21: Classify different input sources into scenarios; Step 22: Perform numbering for the current scene; Step 23: Determine whether the current scene has been learned. If so, output the learned fragrance settings. If not, output the default fragrance settings. Step 3: Output the corresponding fragrance into the car according to the fragrance type selected in step 2.

[0008] Preferably, in the novel intelligent fragrance and emotional atmosphere control method, the determination in step 23 is processed by an onboard processing chip, wherein the onboard processing chip model includes NXP S32K146 / 148.

[0009] Preferably, the novel intelligent fragrance and emotional atmosphere control method, after outputting the fragrance setting in step 23, confirms whether the user has changed the setting; If the user changes the settings, the current scene output settings are recorded and marked as learned and / or updated; If the user has not changed the settings, the system will periodically check whether the scene has been updated. If so, the fragrance selection control will start again from step 2. If not, the system will return to the user's setting change.

[0010] Preferably, in the novel intelligent fragrance and emotional atmosphere control method, the driver fatigue detection information (DMS) includes normal state, fatigue state and inattention state; Ambient light information includes warm, soft and cool tones Intelligent driving information includes highway sections, elevated sections, urban sections and the activation of assisted driving mode; Vehicle body sensor information includes sunny days, dark nights, rainy days, and dark nights and rainy days; The user information includes no input, fragrance A, fragrance B, and fragrance C.

[0026] In Table 1, different inputs are classified into multiple states during the implementation process. Each state corresponds to a unique code, and the corresponding states have scenario priorities, which can be divided into S: high-risk scenario A: risky scenario B: normal driving scenario C: low-risk scenario. The learned fragrance output or the default fragrance output can be output based on whether the scenario has been learned.

[0027] The determination in step 23 is processed by an onboard processing chip, wherein the onboard processing chip model includes NXP S32K146 / 148.

[0028] Example 2 Based on the first embodiment, Figure 2 As shown, when the user reselects in this scenario, re-learning and memorization are performed, and the fragrance settings are continuously updated as the scene changes and the current scene information is learned, maintaining the interaction between the fragrance system and the driver and scene changes throughout the driving process.

[0029] The specific operation is as follows: after outputting the fragrance setting in step 23, confirm whether the user has changed the setting; If the user changes the settings, the current scene output settings are recorded and marked as learned and / or updated; If the user has not changed the settings, the system will periodically check whether the scene has been updated. If so, the fragrance selection control will start again from step 2. If not, the system will return to the user's setting change.
