Description

Technical Field

[0001] The present invention relates to the field of automobile control technology, and in particular to an automobile fragrance control system and a control method. Background Art

[0002] Fragrance systems have become an indispensable part of car cabins. They can cover certain special odors in the car, such as luggage odor, tobacco odor, fish odor, and small animal body odor, making the air in the car fresh while also expressing the user's aesthetic taste.

[0003] However, existing car fragrance systems have some problems: every fragrance user should find a fragrance that suits them and is similar to their personality, so that people can resonate with this fragrance when using it and highlight the user's characteristics and character. However, existing car fragrance systems have a single fragrance and can only meet the user's needs for self-adjustment of the front, middle and back fragrances; existing car fragrance systems are more user-active in adjusting the fragrance volume and timing, making it difficult to adjust the fragrance taste and volume at the right time.

[0004] To address this technical issue, a prior art document titled "A Fragrance System and Fragrance Release Method" proposes a fragrance control system comprising a fragrance box, an off-vehicle sensor assembly, and a controller. The fragrance box contains at least three different fragrance materials, along with a corresponding fragrance-releasing fan for each fragrance material, and a fragrance-releasing port. The off-vehicle sensor assembly detects the vehicle's environmental information. The controller controls the operating state of the fragrance-releasing fan corresponding to each fragrance material based on the vehicle's environmental information detected by the off-vehicle sensor assembly, thereby adjusting the type of fragrance released by the fragrance box. This fragrance system has multiple modes, allowing for targeted adjustments based on customer needs, highlighting the user's unique characteristics and personality. It can also release fragrance based on environmental information, automatically adjusting the appropriate fragrance flavor and volume at the appropriate time.

[0005] However, this fragrance system also has some problems. It considers relatively few adjustment factors, such as only considering environmental factors. Such an adjustment control mode is relatively simple and often cannot provide a fragrance atmosphere that satisfies the passengers. In actual applications, it is often the case that a relatively strong fragrance is provided when the passengers do not need fragrance, and when the passengers need fragrance, the fragrance cannot be provided to the passengers in a timely and accurate manner. The single control mode leads to complaints from the passengers. Summary of the Invention

[0024] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] The present application relates to a car fragrance control system. The control system of the present application is capable of controlling the fragrance inside the car. By collecting environmental information and passenger information, and conducting a comprehensive analysis of the environmental information and passenger information, it is determined whether fragrance needs to be provided to the passengers. If fragrance is provided, the location, concentration, time and mode of the fragrance are determined. The fragrance control system of the present application is capable of controlling and adjusting the fragrance inside the car in a targeted manner, taking into full consideration the current environmental information inside and outside the car and the identity information of the passengers to perform targeted control, ensuring that the adjustment of the fragrance inside the car meets the requirements of the passengers to the greatest extent, providing the passengers with the best comfortable environment, and not causing complaints from the passengers.

[0026] Specifically, such as Figures 1-2 The automobile fragrance control system of the present application includes a fragrance providing module, an environmental information collection module, an occupant information collection module and a control module. The fragrance providing module is arranged in the air-conditioning duct to provide fragrance to any position in the car. Different from the prior art that only installs the fragrance unit in the air-conditioning system duct at the dashboard, the present application installs the fragrance unit in multiple positions in the car, which can provide fragrance for the car in an all-round way and provide different fragrance modes; the environmental information collection module is used to collect the current external and internal environmental information of the vehicle. By collecting the external and internal environmental information of the vehicle, the fragrance can be adjusted in a targeted manner. For example, in some cases where pollution is more serious, the fragrance concentration can be increased. Cover up polluting odors and improve the comfort of the vehicle environment; the passenger information collection module is used to collect passenger information in the vehicle. By collecting passenger information in the vehicle, the fragrance can be adjusted according to the passenger. For example, if the passengers in the vehicle have different preferences, adaptive adjustments can be made according to the passengers' preferences; the control module sends control instructions to the fragrance providing module based on environmental information and passenger information, indicating whether fragrance needs to be provided to the passengers, the location of fragrance provision, the concentration and time of fragrance, and the fragrance mode. The control module is the central module of the entire fragrance control system. It formulates control instructions for the fragrance providing module through comprehensive analysis of the collected information, and finally sends corresponding control instructions to the fragrance providing module to achieve the purpose of precise control.

[0027] Specifically, the specific control method of the automobile fragrance control system of this application is: S1. Collect the current vehicle external and internal environment information; S2. Collecting passenger information in the vehicle; S3, determining whether it is necessary to provide fragrance for the occupants based on the vehicle's external environment information, the vehicle's internal environment information, and the occupant information in the vehicle; First, determine whether it is necessary to provide fragrance for the passengers in the car. If it is not necessary to provide fragrance, just turn off the fragrance unit. Only when it is necessary to provide fragrance, the next step is required. S4. When it is determined that fragrance is needed for the occupants, the central fragrance unit on the instrument panel and the door fragrance units in the doors are controlled based on the vehicle's external environment information, the vehicle's internal environment information, and the occupant information to adjust the fragrance position, fragrance concentration, fragrance mode, and fragrance duration; This application controls the fragrance unit in all aspects, involving the location, concentration, mode and time of fragrance provision, ensuring that the fragrance provided meets the needs of the passengers in the car and does not cause complaints from the passengers, providing a more comfortable in-car environment for the passengers.

[0028] In some embodiments of the present application, this embodiment optimizes the above-mentioned fragrance providing module. Specifically, the fragrance providing module of this embodiment includes multiple central fragrance units and multiple door fragrance units, such as Figure 2 As shown, multiple central fragrance units are arranged at intervals along the Y direction at the air inlet of the air-conditioning duct in the instrument panel; the door fragrance units are set at the air outlet of the built-in air-conditioning duct in the door.

[0029] In order to provide more targeted and precise fragrance adjustment for the passengers, this embodiment adds an air-conditioning duct in the car door. The air-conditioning duct in the car door is connected to the air-conditioning system. The air-conditioning system blows air into the air-conditioning duct in the car door. The car door fragrance unit is installed at the air outlet of the air-conditioning duct in the car door. By controlling the opening and closing of the air-conditioning duct in the car door, the opening and closing of the corresponding car door fragrance unit can be controlled.

[0030] The central fragrance unit is installed at the air inlet of the air-conditioning duct inside the dashboard, so that when the air-conditioning duct inside the dashboard is turned on, you can choose whether to provide fragrance into the car.

[0031] The central fragrance unit and the door fragrance unit of this embodiment both adopt the same fragrance unit structure. The specific structure can refer to the application number "202311108977.0" entitled "A fragrance device". Each fragrance unit is an independent structure with the functions of self-opening and closing and concentration adjustment. When the fragrance unit needs to be opened and closed, it is only necessary to adjust the valve on the fragrance unit. When the concentration needs to be adjusted, it can be done by adjusting the fan of the fragrance unit or by increasing the wind speed in the air duct or pipe.

[0032] Each fragrance unit of this embodiment can be equipped with multiple fragrance bottles as in the prior art described above, or each fragrance unit can have only one fragrance bottle; the central fragrance unit and the door fragrance units of this embodiment store fragrance bottles of different scents, for example, the central fragrance unit on the dashboard stores three different fragrance bottles, and the door fragrance units have four different fragrance bottles, or the central fragrance unit and the door fragrance units can store the same fragrance bottles.

[0033] In this embodiment, different fragrance modes can be realized by opening different fragrance bottles. Passengers can set their favorite fragrance modes according to their needs. Subsequently, as long as the passenger is detected to get on the car, the preference can be automatically called to control the fragrance to the fragrance mode that the passenger likes.

[0034] In this embodiment, four dedicated door fragrance units are set on the four doors, and four dedicated air-conditioning ducts are designed on the door guard panels. The door fragrance units are hidden in the ducts, and the external design is an easily removable shell, and the internal fragrance bottles are replaceable. The adjustment system sets independent air outlet ducts for the four doors, so that the fragrance of the four doors will not be confused with the fragrance on the dashboard, ensuring the three-dimensional surround effect of the fragrance. When the customer turns on the fragrance on the central control screen, the user will be prompted with a variety of fragrance types of different styles. After selecting the type, the user will be prompted to place the fragrance bottles of this type. After the placement is completed, the system can determine whether the placement is correct through the identification code of each fragrance and display it on the central control screen. The central fragrance unit at the instrument and the door fragrance units of the four doors can be controlled by the controller, which can achieve the surround three-dimensional effect of the fragrance and the coordination and superposition of different levels. Each fragrance unit has an independent chip and opening mechanism, which can independently control the speed of fragrance generation and monitor the dosage to ensure the normal operation of the entire system.

[0035] In a further embodiment of the present application, this embodiment optimizes step S3 described above. In actual application, this embodiment requires the collection of environmental information and occupant information. Environmental information includes in-vehicle and out-vehicle environmental information. Out-vehicle environmental information primarily includes vehicle location and weather, while in-vehicle environmental information primarily includes in-vehicle temperature, humidity, and air quality. Occupant information includes occupant distribution information and occupant identity information. Occupant distribution information primarily refers to the seating positions of occupants in the vehicle, while occupant identity information primarily refers to the occupant's identity. Obtaining the occupant's identity allows for matching it with pre-stored preferences and taboos corresponding to the occupant.

[0036] In actual application, after obtaining environmental information and passenger information, it can be preliminarily determined whether it is necessary to provide fragrance to the passengers in the car. Under normal circumstances, the fragrance control system defaults to providing fragrance to the passengers in the car, and the fragrance will only be turned off in special circumstances.

[0037] The obtained passenger identity information is compared with the pre-stored identity information. If it is found that there is a passenger in the car who is allergic to or dislikes the fragrance in the car, the car fragrance is turned off. In this case, if the fragrance is provided, it may cause discomfort to the passengers in the car. To avoid this situation, all fragrance units should be turned off immediately. In addition, the system analyzes the vehicle's location information and automatically turns off the fragrance if the location indicates the vehicle is at a gas station and the fragrance is on. This location-based activation and deactivation of the fragrance system is primarily used in certain scenarios where volatile gases are present in the external environment. To prevent the fragrance from masking the passengers' sense of smell and causing them to ignore the safety hazards posed by these gases, deactivating the fragrance can mitigate this risk. Practical applications are not limited to gas stations but can also be applied to chemical plants, pharmaceutical factories, and more.

[0038] Turning off the fragrance based on the passenger identity information and turning off the fragrance based on the vehicle location information are parallel, that is, no matter which situation occurs, the fragrance needs to be turned off immediately.

[0039] In a preferred embodiment of the present application, this embodiment optimizes the above-mentioned step S4. Specifically, when it is determined that the fragrance needs to be turned on, that is, when there are no passengers in the car who are allergic or do not like fragrance and the vehicle is not at a gas station, the fragrance is turned on, and then the fragrance needs to be further controlled.

[0040] First, the specific location of the fragrance unit is determined by the distribution of passengers in the car. For example, if there is only the driver in the car, only the central fragrance unit on the dashboard and the door fragrance unit of the main driver's door need to be turned on. The fragrance units in other positions can be closed. This can provide a good fragrance atmosphere for the main driver without wasting too much fragrance.

[0041] After determining the fragrance unit that needs to be turned on, a judgment can be made based on the passenger identity information. For example, if it is recognized that there is a passenger in the current car who has stored personal preference information in the control system in advance, the passenger's preferences can be directly called to determine the fragrance mode; if no passenger in the car has stored personal preferences in the control system, the fragrance mode will be adjusted according to the external weather in the environmental information, such as a cloudy fragrance mode for cloudy days, a sunny fragrance mode for sunny days, and a rainy fragrance mode for rainy days.

[0042] After determining the fragrance mode, the concentration of the fragrance is further determined. The concentration of the fragrance is directly linked to the senses of the occupants. In this embodiment, there are two adjustment factors for controlling the fragrance concentration, one is the air quality, and the other is the air temperature and humidity. When the air quality is poor, mainly when the formaldehyde content in the car air is detected to be relatively high, the fragrance concentration needs to be increased. The higher the formaldehyde concentration in the car, the higher the corresponding fragrance concentration, that is, the fragrance concentration and the formaldehyde concentration in the car are positively correlated; the higher the air temperature in the car, the lower the fragrance concentration. This is mainly because when the temperature in the car is high, the fragrance will aggravate the sensory stimulation of the occupants and cause adverse effects. Therefore, the temperature in the car is negatively correlated with the fragrance concentration. The humidity in the car is also negatively correlated with the fragrance concentration. This is mainly because when the humidity in the car is high, if the fragrance atomization interval is too short, the fragrance particles will condense. Therefore, the humidity in the car is negatively correlated with the fragrance concentration in the car. In actual application, the standard relationship curve of formaldehyde concentration, temperature, humidity and fragrance concentration can be calibrated. In subsequent actual application, the fragrance concentration can be determined according to the standard relationship curve by collecting the formaldehyde concentration, temperature and humidity in the car.

[0043] The fragrance concentration of this embodiment is controlled by the fragrance release speed of the fragrance bottle. When the fragrance concentration needs to be increased, the fragrance release speed is increased, and when the fragrance concentration needs to be reduced, the fragrance release speed is reduced.

[0044] After the fragrance concentration is determined, the fragrance time is determined. There are standard regulations for the fragrance release time. A single continuous release should not exceed 15 minutes, and the interval should be at least 5 minutes.

[0045] In actual application, the control operation can be performed according to the following methods: like Figure 1 As shown, the passenger identity information and vehicle location information are collected, and the obtained passenger identity information is compared with the pre-stored identity information. If it is found that there is a passenger in the car who is allergic to fragrance or does not like the fragrance in the car, the fragrance in the car is turned off; the obtained vehicle location information is analyzed, and when the location information shows that the current vehicle is at a gas station, the fragrance in the car is turned off; The fragrance is activated when there are no passengers in the vehicle who are allergic or do not like fragrance and the vehicle is not at a gas station. The specific location of the fragrance unit to be activated is determined based on the distribution of passengers in the vehicle. The obtained passenger identity information is compared with the pre-stored identity information. If the passenger's preferred pattern is found in the compared information, the fragrance in the car is adjusted to the passenger's preferred fragrance pattern; if the passenger's preferred pattern is not found in the compared information, the fragrance pattern is adjusted according to the external weather; Detect the air quality, temperature and humidity in the car, and determine the fragrance concentration based on the formaldehyde concentration, temperature and humidity in the car; A single continuous release should not exceed 15 minutes, with an interval of at least 5 minutes; The fragrance unit in the car is controlled to function according to the determined fragrance position, fragrance mode, fragrance concentration and fragrance time.
