Description

Technical Field

[0001] This application relates to the field of in-vehicle fragrance technology, and in particular to an in-vehicle fragrance control method, system, smart terminal and storage medium. Background Technology

[0002] In-car fragrance systems generate aromas through fragrance generators, which are then dispersed into the vehicle's interior via ventilation ducts, thereby maintaining clean air and creating a more comfortable in-car atmosphere.

[0003] In related technologies, in-vehicle fragrance systems are installed in front of the car's central control unit and typically include a fragrance box and a vaporizer. The fragrance box contains liquid fragrance. When a person needs to turn on the in-vehicle fragrance system, they need to press the switch of the in-vehicle fragrance system and select the type and concentration of fragrance to be released. This causes the vaporizer to be inserted into the corresponding fragrance to atomize and evaporate the fragrance and release it into the car cabin, allowing the fragrance to fill the cabin passively and undisturbed.

[0004] Regarding the aforementioned technologies, when a person presses the switch of the in-vehicle fragrance system to release the fragrance, the fragrance passively diffuses freely in the car, causing the seats closer to the fragrance release vent to feel the fragrance first, while the seats farther away from the fragrance release vent require a certain amount of time to feel the fragrance. This results in low synchronization between the people in the car and the fragrance, and there is still room for improvement. Summary of the Invention

[0005] To improve the synchronization of the in-vehicle fragrance experience for occupants, this application provides an in-vehicle fragrance control method, system, smart terminal, and storage medium.

[0006] Firstly, this application provides a method for controlling in-vehicle fragrance, employing the following technical solution:

[0007] A method for controlling in-vehicle fragrance includes:

[0010] The voice information is analyzed to determine the fragrance release type and concentration.

[0011] Control the in-vehicle fragrance device to release fragrance based on the fragrance type corresponding to the fragrance release type information;

[0012] Obtain the airflow speed information of the air vents corresponding to each seat in the vehicle;

[0013] The fragrance evaporation rate is determined by analyzing the air conditioner's airflow speed and fragrance release concentration information.

[0014] The system controls the in-vehicle fragrance device to release fragrance at a rate corresponding to the fragrance evaporation rate information, and controls the preset air conditioning device to start so that the evaporated fragrance can be delivered to the corresponding location through the air conditioning duct and air conditioning vent.

[0015] By adopting the above technical solution, the in-vehicle fragrance device is connected to the air conditioning duct according to voice information, and the fragrance release type and concentration information are determined according to the voice information. This allows the in-vehicle fragrance device to release the fragrance corresponding to the fragrance release type information. The air conditioning vent speed information is detected, and the fragrance evaporation speed information is determined according to the air conditioning vent speed information and the fragrance release concentration information. The in-vehicle fragrance device is controlled to evaporate the fragrance according to the fragrance evaporation speed information, and the air conditioning device is controlled to deliver the evaporated fragrance to the corresponding location through the air conditioning duct and air conditioning vent. This allows the people in the car to feel the fragrance simultaneously, thereby improving the synchronicity of the in-vehicle fragrance experience.

[0016] Optionally, methods for controlling the connection between the preset in-vehicle fragrance device and the air conditioning duct based on voice information include:

[0017] Based on the voice information, obtain the voice capture time information for different seats in the vehicle;

[0018] The times corresponding to the voice capture time information are sorted and compared to determine the fastest voice capture time information;

[0019] The seat corresponding to the fastest voice capture time is identified to determine the fragrance control location information;

[0020] The system controls the in-vehicle fragrance device to activate the fragrance release channel, which is connected to the air conditioning duct of the seat corresponding to the fragrance control location information.

[0021] By adopting the above technical solution, when voice information is detected, the voice capture time information of different seats in the vehicle is detected and sorted to obtain the fastest voice capture time information. The seat corresponding to the fastest voice capture time information is identified to determine the fragrance control position information. The vehicle fragrance device is then controlled to open the fragrance release channel and connect it with the air conditioning duct of the seat corresponding to the fragrance control position information, thereby improving the accuracy of the fragrance release position.

[0022] Optionally, methods for analyzing voice information to determine fragrance release type and fragrance release concentration include:

[0023] Determine whether the semantic features corresponding to the speech information contain information on the fragrance release type and fragrance release concentration;

[0024] If it exists, the fragrance release type information and fragrance release concentration information in the voice information will be directly retrieved;

[0025] If not, the timbre characteristics of the voice information are analyzed to determine the identity information of the control personnel;

[0026] Determine whether the identity information of the controlled personnel exists in the preset historical personnel identity information;

[0027] If it does not exist, output the preset release query message;

[0030] The identity information of the controlled personnel is recorded into the historical personnel identity information, and the fragrance release type information and fragrance release concentration information corresponding to the identity information of the controlled personnel are recorded into the historical fragrance database;

[0031] If it exists, the fragrance release type and fragrance release concentration information corresponding to the control personnel's identity information will be retrieved from the preset historical fragrance database based on the control personnel's identity information.

[0032] By adopting the above technical solution, it is determined whether fragrance release type information and fragrance release concentration information exist in the voice information. If they do not exist, the identity information of the controller is determined based on the voice information. If the identity information of the controller is not in the historical controller identity information, a release inquiry is output, and inquiry feedback information is obtained based on the release inquiry. After determining the fragrance release type information and fragrance release concentration information based on the inquiry feedback information, the controller identity information is recorded into the historical controller identity information, and the fragrance release type information and fragrance release concentration information corresponding to the controller identity information are recorded into the historical fragrance database. If the controller identity information is in the historical controller identity information, the fragrance release type information and fragrance release concentration information corresponding to the controller identity information in the historical fragrance database are directly called, thereby improving the convenience of determining the fragrance release type information and fragrance release concentration information.

[0033] Optionally, it also includes methods for controlling the fragrance after the in-vehicle fragrance device releases the fragrance, specifically including:

[0034] After the in-vehicle fragrance system releases fragrance, it acquires seat video information:

[0035] Each frame of the video footage corresponding to the seating arrangement is analyzed to determine the individual's reaction to the fragrance.

[0036] Determine whether the information provided by the person's response matches the preset requirements for turning off the in-vehicle fragrance system;

[0037] If the requirements are not met, continue to obtain seat video information;

[0038] If the requirements are met, each frame of the image corresponding to the seat video information will be analyzed to determine whether the seat information is turned off.

[0039] The system controls the in-vehicle fragrance system to turn off or reduce the concentration of fragrance for seats corresponding to the seat information that is turned off.

[0040] By adopting the above technical solution, seat video information is detected and each frame of the corresponding seat video information is analyzed to determine the personnel reaction information. When the personnel reaction information meets the requirements of the vehicle fragrance deactivation information, the seat information is deactivated based on the seat video information, thereby controlling the vehicle fragrance device to deactivate and reduce the concentration of the fragrance in the seat corresponding to the deactivated seat information, thereby improving the personnel's adaptability to the fragrance.

[0041] Optionally, methods for controlling the in-vehicle fragrance device to turn off or reduce the concentration of fragrance for seats corresponding to those with off seat information include:

[0044] Obtain information on the speed and concentration of fragrance release from the air conditioner;

[0045] The fragrance absorption rate information is determined by analyzing the release rate information corresponding to the fragrance release rate information and the fragrance concentration information corresponding to the fragrance concentration information.

[0046] The preset inhalation device is controlled to absorb fragrance at a speed corresponding to the fragrance absorption speed information.

[0047] By adopting the above technical solution, the in-vehicle fragrance device is controlled to turn off the fragrance of the seat corresponding to the seat information being turned off, and the air curtain device is controlled to blow air around the seat corresponding to the seat information being turned off to form an isolation air curtain to isolate the seat corresponding to the seat information being turned off. The fragrance release speed and fragrance concentration information of the air conditioner are detected, and the fragrance absorption speed information is determined based on the fragrance release speed and fragrance concentration information. The air intake device is then controlled to absorb the isolated fragrance according to the fragrance absorption speed information, thereby improving the efficiency and convenience of fragrance removal.

[0048] Optionally, methods for obtaining fragrance concentration information include:

[0049] Obtain information on fragrance release time and fragrance release speed;

[0050] Calculate the product between the time corresponding to the fragrance release time information and the speed corresponding to the fragrance release rate information, and define the calculated product as the fragrance release amount information;

[0051] The fragrance uniformity time information is determined based on the release rate corresponding to the fragrance release rate information and the volume corresponding to the preset vehicle interior volume information.

[0052] Determine whether the fragrance release time information is greater than the fragrance uniformity time information;

[0053] If it is not greater than, then the fragrance concentration information is determined by analyzing the volume corresponding to the preset single seat volume information, the leakage rate corresponding to the preset leakage rate information, the release time corresponding to the fragrance release time information, and the fragrance release amount corresponding to the fragrance release amount information.

[0054] If the value is greater than the specified value, the fragrance concentration information will be determined by analyzing the volume corresponding to the vehicle's internal volume information, the leakage rate corresponding to the preset leakage rate information, the release time corresponding to the fragrance release time information, and the fragrance release amount corresponding to the fragrance release amount information.

[0055] By employing the above technical solution, the fragrance release time and release rate information are detected, and the fragrance release amount information is obtained by calculating the product of the fragrance release time and release rate information. The fragrance uniformity time information is determined based on the fragrance release rate information and the vehicle's interior volume information. When the fragrance release time information is not greater than the fragrance uniformity time information, the fragrance concentration information is determined based on the single seat volume information, fragrance release time information, leakage rate information, and fragrance release amount information. When the fragrance release time information is greater than the fragrance uniformity time information, the fragrance concentration information is determined based on the vehicle's interior volume information, leakage rate information, fragrance release time information, and fragrance release amount information, thereby improving the accuracy of fragrance concentration information determination.

[0056] Optionally, it also includes methods for controlling the fragrance after the inhalation device absorbs the fragrance, specifically including:

[0057] Get the remaining fragrance concentration information for the seat corresponding to the closed seat information;

[0058] Determine whether the remaining fragrance concentration is less than the preset baseline remaining concentration.

[0059] If it is not less than, then control the inhalation device to continue absorbing the fragrance at the speed corresponding to the fragrance absorption speed information;

[0060] If it is less than, then the personnel response information corresponding to the personnel response information is analyzed to determine the comfort fragrance type information;

[0061] The in-vehicle fragrance system is controlled to release fragrance to the seats corresponding to the closed seat information based on the fragrance type corresponding to the comfort fragrance type information.

[0062] By adopting the above technical solution, the remaining fragrance concentration information is detected. When the remaining fragrance concentration information is not less than the baseline remaining concentration information, the inhalation device is controlled to continue absorbing fragrance at the speed corresponding to the fragrance absorption speed information. When the remaining fragrance concentration information is less than the baseline remaining concentration information, the comfortable fragrance type information is determined based on the personnel reaction information, thereby controlling the in-vehicle fragrance device to release fragrance to the seat corresponding to the closed seat information with the comfortable fragrance type information, thereby improving the comfort of the personnel with the fragrance.

[0063] Secondly, this application provides an in-vehicle fragrance control system, which adopts the following technical solution:

[0064] A vehicle-mounted fragrance control system includes:

[0065] The acquisition module is used to acquire voice information and air conditioner airflow speed information;

[0069] Thirdly, this application provides a smart terminal, which adopts the following technical solution:

[0070] A smart terminal includes a memory and a processor, wherein the memory stores a computer program that can be loaded by the processor and executed as any of the above-described in-vehicle fragrance control methods.

[0071] By adopting the above technical solution, and by operating the smart terminal, the processor loads and executes a computer program for a vehicle fragrance control method stored in the memory, thereby completing the control of the vehicle fragrance system and improving the synchronicity of the vehicle fragrance experience for the user.

[0072] Fourthly, this application provides a computer storage medium capable of storing corresponding programs, which facilitates the synchronization of the in-vehicle occupants' experience with the in-vehicle fragrance, and adopts the following technical solution:

[0073] A computer-readable storage medium storing a computer program that can be loaded by a processor and executed any of the above-described in-vehicle fragrance control methods.

[0074] By adopting the above technical solution, a computer program for a vehicle fragrance control method is stored in a computer-readable storage medium, thereby enabling the processor to directly load and execute the computer program stored in the memory, thereby completing the control of the vehicle fragrance and improving the synchronization of the vehicle fragrance experience for the user.

[0075] In summary, this application includes at least one of the following beneficial technical effects:

[0076] 1. By controlling the connection between the in-vehicle fragrance device and the air conditioning duct according to voice information, and determining the fragrance release type and concentration information according to the voice information, the in-vehicle fragrance device is controlled to release the fragrance corresponding to the fragrance release type information. The air conditioning vent speed information is detected, and the fragrance evaporation speed information is determined according to the air conditioning vent speed information and the fragrance release concentration information. The in-vehicle fragrance device is controlled to evaporate the fragrance according to the fragrance evaporation speed information, and the air conditioning device is controlled to deliver the evaporated fragrance to the corresponding location through the air conditioning duct and air conditioning vent, so that the people in the car can feel the fragrance at the same time, thereby improving the synchronicity of the people in the car feeling the in-vehicle fragrance.

[0077] 2. When voice information is detected, the voice capture time information of different seats in the car is detected and sorted to obtain the fastest voice capture time information. The seat corresponding to the fastest voice capture time information is identified to determine the fragrance control position information.

[0078] 3. By determining whether fragrance release type and fragrance release concentration information exist in the voice information, if not, the controller's identity information is determined based on the voice information. If the controller's identity information is not in the historical controller identity information, a release inquiry is output, and the inquiry feedback information is obtained based on the release inquiry information. The fragrance release type and fragrance release concentration information are determined based on the inquiry feedback information.

[0086] To make the purpose, technical solution, and advantages of this application clearer, the following description is provided in conjunction with the appendix. Figure 1-7 The present application will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the application.

[0087] This application discloses a car central control unit, an air conditioning unit, an air conditioning duct, an air conditioning vent, and a car fragrance device. The car central control unit controls the opening and closing of the air conditioning unit and the car fragrance device separately via electrical signals. The air conditioning duct and the air conditioning vent are connected, so that the air conditioning unit delivers air from the air conditioning duct and the air conditioning vent to different seats in the car. The car fragrance device is connected to the air conditioning duct, so when the car fragrance device releases fragrance into the air conditioning duct, the air conditioning unit delivers the fragrance in the air conditioning duct to different seats in the car through the air conditioning vent, thereby improving the synchronicity of the car fragrance experience for the occupants.

[0088] Reference Figure 1 This application discloses a method for controlling in-vehicle fragrance, including the following steps:

[0089] Step S100: Obtain voice information from the occupants inside the vehicle.

[0090] Voice information refers to the voices of people speaking inside the car, which are captured by microphones installed in different seats and uploaded to the car's central control system.

[0091] Step S101: Control the preset in-vehicle fragrance device to connect with the air conditioning duct according to the voice information.

[0092] The in-vehicle fragrance system refers to a device used to release in-vehicle fragrances. It includes a fragrance pipe, different types of fragrance sticks, and a motor. The fragrance pipe has different areas for inserting the fragrance sticks and different outlets. The air conditioning duct has inlets corresponding to the outlets. When the motor drives the fragrance pipe to rotate, the outlets and inlets align, allowing different fragrances to enter the air conditioning duct. The in-vehicle fragrance system is connected to the air conditioning duct based on voice commands, allowing the fragrance to be delivered to different seats in the vehicle. The method for controlling the connection between the in-vehicle fragrance system and the air conditioning duct based on voice commands is described in [reference needed]. Figure 2 The steps.

[0093] Step S102: Analyze the voice information to determine the fragrance release type information and fragrance release concentration information.

[0094] Among them, fragrance release type information refers to different scents, and fragrance release concentration information refers to the concentration of fragrance in the car. Both fragrance release type and concentration information are obtained by the car's central control system through semantic feature recognition or timbre feature recognition based on voice information. For specific methods, please refer to [link to relevant documentation]. Figure 3 The steps.

[0095] Step S103: Control the in-vehicle fragrance device to release fragrance based on the fragrance type corresponding to the fragrance release type information.

[0096] After determining the fragrance release type information, the vehicle fragrance device is controlled to release the fragrance of the corresponding fragrance type. The specific release method is as follows: the motor controls the outlet of the area corresponding to the fragrance release type information on the fragrance duct to connect with the inlet of the air conditioning duct, so that the fragrance corresponding to the fragrance release type information is released into the air conditioning duct.

[0097] Step S104: Obtain the airflow speed information of the air vents corresponding to each seat in the vehicle.

[0098] Among them, the air conditioning air outlet speed information refers to the air outlet speed corresponding to each seat in the car. The air conditioning air outlet speed information is selected and controlled by the people in the car on the central control of the car.

[0099] Step S105: Analyze the airflow speed information and fragrance release concentration information to determine the fragrance evaporation rate information.

[0100] Among them, the fragrance evaporation rate information refers to the amount of fragrance entering the air conditioning duct from the fragrance pipe in the vehicle fragrance device per unit time. It is obtained by analyzing the air conditioning air outlet speed information and fragrance release concentration information retrieved by the vehicle's central control system. The analysis method is as follows: when the fragrance concentration corresponding to the fragrance release concentration information is constant, the air outlet speed corresponding to the air conditioning air outlet speed information is inversely proportional to the evaporation speed corresponding to the fragrance evaporation rate information. That is, the higher the air outlet speed corresponding to the air conditioning air outlet speed information, the lower the evaporation speed corresponding to the fragrance evaporation rate information, thus ensuring that the fragrance release concentration information is quantitative.

[0101] Step S106: Control the in-vehicle fragrance device to release fragrance at the evaporation rate corresponding to the fragrance evaporation rate information, and control the preset air conditioning device to start so that the evaporating fragrance can be delivered to the corresponding location through the air conditioning duct and air conditioning vent.

[0102] The air conditioning unit refers to the air conditioner installed in the vehicle. Air vents are installed in front of different seats inside the vehicle. The air conditioning unit delivers air from the air conditioning duct to different locations inside the vehicle through these vents. The corresponding location is the point where the air vent exits. After determining the fragrance evaporation rate, the in-vehicle fragrance device releases the fragrance into the air conditioning duct at the evaporation rate corresponding to this information. This allows the air conditioning unit to deliver the fragrance from the duct to the corresponding location, thereby improving the synchronicity of the fragrance experience for the occupants.

[0103] Reference Figure 2 The method for controlling the connection between the preset in-vehicle fragrance device and the air conditioning duct according to voice information includes the following steps:

[0104] Step S200: Obtain voice capture time information for different seats in the vehicle based on the voice information.

[0105] Among them, the voice capture time information refers to the time when the voice information is detected in different seats after the existence of voice information is determined. It is obtained by the car's central control system calling the detection time of the microphones in different seats.

[0106] Step S201: Sort and compare the times corresponding to the voice capture time information to determine the fastest voice capture time information.

[0107] Among them, the fastest voice capture time information refers to the fastest time to detect voice information among different seats. The voice capture time information is called by the car's central control system and sorted by size to obtain the smallest voice capture time information, thereby determining the fastest voice capture time information.

[0108] Step S202: Identify the seat corresponding to the fastest voice capture time information to determine the fragrance control location information.

[0109] Among them, the fragrance control location information refers to the specific location where the air conditioning vent delivers fragrance. It is obtained by the car's central control system calling the fastest voice capture time information and identifying the seat corresponding to the fastest voice capture time information. For example, if the seat corresponding to the fastest voice capture time information is the driver's seat, then the fragrance control location information is the driver's seat.

[0110] Step S203: Control the in-vehicle fragrance device to open the fragrance release channel and connect it with the air conditioning duct of the seat corresponding to the fragrance control location information.

[0111] Once the fragrance control location information is determined, the in-vehicle fragrance device is controlled to open the fragrance release channel, connecting the fragrance release channel with the air conditioning duct of the seat corresponding to the fragrance control location information. This allows the fragrance to be delivered to the seat corresponding to the fragrance control location information, improving the synchronicity of the fragrance experience for the person.

[0112] Reference Figure 3 A method for determining fragrance release type and concentration information based on voice information includes the following steps:

[0113] Step S300: Determine whether there is fragrance release type information and fragrance release concentration information in the semantic features corresponding to the voice information.

[0114] In this process, semantic feature recognition of voice information is performed to determine whether there is specific information about the type and concentration of fragrance release in the voice information. For example, the release of mint fragrance at a concentration of 10 ml per cubic meter can determine whether the person has given instructions on the specific type and concentration of fragrance release.

[0115] Step S301: If it exists, directly call the fragrance release type information and fragrance release concentration information in the voice information.

[0116] If the semantic features corresponding to the voice information contain fragrance release type information and fragrance release concentration information, it indicates that the person has given specific instructions on fragrance release type information and fragrance release concentration information. Therefore, the car's central control system directly calls the fragrance release type information and fragrance release concentration information in the voice information.

[0117] Step S302: If not, analyze the timbre characteristics of the voice information to determine the identity information of the control personnel.

[0118] Among them, the control personnel identity information refers to the identity of the person who issued the voice information when there is no information on the fragrance release type and fragrance release concentration in the voice information. The control personnel identity information is obtained by the car's central control system calling the voice information and recognizing the timbre characteristics of the voice information.

[0119] If the semantic features corresponding to the voice information do not contain information on the fragrance release type and fragrance release concentration, it indicates that the person did not give specific instructions on the fragrance release type and fragrance release concentration, but only gave instructions such as "turn on the fragrance". Therefore, the identity information of the control person can be obtained by analyzing the timbre features of the voice information.

[0120] Step S303: Determine whether the identity information of the controlled personnel exists in the preset historical personnel identity information.

[0121] The historical user identity information refers to the identities of those who have previously controlled the in-car air freshener, which are recorded and retrieved by the car's central control system. By determining whether the user's identity information exists in the historical user identity information, it can be determined whether the user has previously used the in-car air freshener.

[0122] Step S3031: If it does not exist, output the preset release query information.

[0123] Among them, the release inquiry information refers to the voice inquiry output to the people in the vehicle regarding the type and concentration of fragrance release when the control personnel's identity information does not exist in the historical personnel identity information. The release inquiry information is set by those skilled in the art according to the actual situation, and will not be elaborated here. For example: Please enter the type and concentration of fragrance release.

[0124] Step S30311: Obtain inquiry feedback information based on the released inquiry information.

[0125] Among them, the inquiry feedback information refers to the voice response of the person to the release of inquiry information, which is detected by the microphones in each seat of the car and uploaded to the car's central control, for example: releasing 10 milliliters of mint fragrance per cubic meter.

[0126] Step S30312: Analyze the semantic features corresponding to the query feedback information to determine the fragrance release type information and fragrance release concentration information.

[0127] In this step, the fragrance release type information refers to the type of fragrance released based on the query feedback information, and the fragrance release concentration information refers to the concentration of the released fragrance based on the query feedback information, which is obtained by the car's central control system by calling the query feedback information for semantic feature recognition.

[0128] Step S30313: Record the control personnel's identity information into the historical personnel identity information, and record the fragrance release type information and fragrance release concentration information corresponding to the control personnel's identity information into the historical fragrance database.

[0129] The historical fragrance database stores fragrance release type and concentration information corresponding to the identity information of the controller. This database is created by the vehicle's central control system (NCS) by recording past controller identity information and the corresponding fragrance release type and concentration information. The NCS retrieves and records the controller's identity information from historical records, and also retrieves and records the corresponding fragrance release type and concentration information into the historical fragrance database. This facilitates subsequent determination of fragrance release type and concentration information based on historical data.

[0130] Step S3032: If it exists, then according to the identity information of the controller, call the fragrance release type information and fragrance release concentration information corresponding to the identity information of the controller in the preset historical fragrance database.

[0131] The historical fragrance database refers to a database that stores fragrance release type and concentration information corresponding to the identity information of the control personnel. Different control personnel identity information corresponds to different fragrance release type and concentration information. For example, personnel A corresponds to 15 ml of rose fragrance per cubic meter, and personnel B corresponds to 10 ml of mint fragrance per cubic meter.

[0132] If the controller's identity information exists in the historical controller information, it means that the controller has previously controlled the vehicle fragrance system. Therefore, the controller's identity information is directly input, and the fragrance release type information and fragrance release concentration information corresponding to the controller's identity information are matched and output from the historical fragrance database. For example, if the controller's identity information is A, then the fragrance release type information is rose fragrance, and the fragrance release concentration information is 15 ml per cubic meter.

[0133] Reference Figure 4 The in-vehicle fragrance control method also includes a method for controlling the fragrance after the in-vehicle fragrance device releases the fragrance, specifically including the following steps:

[0134] Step S400: After the fragrance is released by the in-vehicle fragrance device, the seat video information is obtained.

[0135] Among them, seat video information refers to the video taken of each seat in the car after the in-car fragrance device releases fragrance. The video is taken by the camera installed in the car and uploaded to the car's central control system.

[0136] Step S401: Analyze each frame of the image corresponding to the seat video information to determine the person's reaction information to the fragrance.

[0137] Among them, the human reaction information refers to the physical and facial reactions of the people in each seat in the car. It is obtained by the car's central control system calling the seat video information and performing image recognition on each frame of the corresponding seat video information. For example, a person waving their hand in front of their face, a person closing their eyes and pressing their temples, etc.

[0138] Step S402: Determine whether the personnel's reaction information meets the preset requirements for turning off the car fragrance.

[0139] Among them, the in-vehicle fragrance deactivation information refers to the person's reaction when the in-vehicle fragrance needs to be turned off, such as waving their hand in front of their face, closing their eyes and pressing their temples, etc., which can be set by those skilled in the art according to the actual situation.

[0140] By determining whether the person's reaction to the information on turning off the in-vehicle fragrance system matches the person's reaction to the information on turning off the in-vehicle fragrance system, it can be determined whether the fragrance or environmental factors are causing discomfort to the person.

[0141] Step S4021: If the requirements are not met, continue to obtain seat video information.

[0142] If the personnel response information does not match the personnel response information corresponding to the in-vehicle fragrance facilitator ...

[0143] Step S4022: If the requirements are met, analyze each frame of the image corresponding to the seat video information to determine whether the seat information is turned off.

[0144] Among them, "closing seat information" refers to the situation where the person's reaction information matches the person's reaction information corresponding to the in-vehicle fragrance closure information. That is, when the fragrance or environmental factors cause the person to feel uncomfortable, the person is in the seat inside the car. The car's central control system calls up the seat video information and performs image feature recognition on each frame of the seat video information. For example, person A is in the driver's seat.

[0145] Step S403: Control the in-vehicle fragrance device to turn off and reduce the concentration of the fragrance for the seat corresponding to the seat information that is turned off.

[0146] Specifically, after determining that fragrance or environmental factors are causing discomfort to a person, and confirming that the uncomfortable person is in a closed seat, the vehicle's fragrance system will turn off the fragrance at the corresponding seat and reduce its concentration. The specific control method is as follows: Figure 5 The steps.

[0147] Reference Figure 5 A method for controlling an in-vehicle fragrance device to turn off or reduce the concentration of fragrance for seats corresponding to the seat information that is turned off includes the following steps:

[0148] Step S500: Control the in-vehicle fragrance device to turn off the fragrance of the seat corresponding to the seat information to be turned off.

[0149] Specifically, the vehicle fragrance control device will turn off the fragrance of the seat corresponding to the seat information being turned off, so that the concentration of the fragrance of the seat corresponding to the seat information being turned off will no longer increase per unit time, making it convenient to reduce the fragrance concentration of the seat corresponding to the seat information being turned off in the future.

[0150] Step S501: Control the preset air curtain device to blow air around the seat corresponding to the closed seat information to form an isolation air curtain to isolate the seat corresponding to the closed seat information.

[0151] The air curtain device refers to the air ducts installed on the roof around each seat in the vehicle. The air ducts are connected to the air conditioning ducts, but not to the in-vehicle fragrance device. Therefore, the air conditioning system can blow the air in the air conditioning ducts out through the air curtain device's air ducts, thereby forming an isolation air curtain around the seat corresponding to the closed seat information, thus minimizing the possibility of fragrance from outside the closed seat information entering the area of ​​the closed seat information.

[0152] Step S502: Obtain information on the speed and concentration of fragrance released by the air conditioner.

[0153] The air conditioner fragrance release speed information refers to the amount of fragrance expelled from the air conditioning duct per unit time; that is, the fragrance release speed information corresponds to the fragrance evaporation speed information. The fragrance concentration information refers to the fragrance concentration at the seat corresponding to the seat with the information turned off. For specific methods of obtaining the fragrance concentration information, please refer to [link / reference needed]. Figure 6 The steps.

[0154] Step S503: Analyze the release rate corresponding to the air conditioner's fragrance release rate information and the fragrance concentration corresponding to the fragrance concentration information to determine the fragrance absorption rate information.

[0155] Among them, the fragrance absorption speed information refers to the speed at which the fragrance in the seat area corresponding to the closed seat information is absorbed. It is obtained by the car's central control system after analyzing the air conditioning fragrance release speed information and fragrance concentration information. The analysis method is as follows: the speed corresponding to the air conditioning fragrance release speed information is the base value of the fragrance absorption speed information. The higher the fragrance concentration corresponding to the fragrance concentration information, the higher the fragrance absorption speed information is based on the speed corresponding to the air conditioning fragrance release speed information.

[0156] Step S504: Control the preset inhalation device to absorb fragrance at the speed corresponding to the fragrance absorption speed information.

[0157] The air intake device refers to the device used by each seat in the vehicle to extract fragrance within its seating area. It can be composed of a fan connected to the air conditioning duct. The air intake device is controlled to extract the fragrance from the seat corresponding to the fragrance absorption speed information, thereby continuously reducing the fragrance in the seat corresponding to the closed seat information.

[0158] Reference Figure 6 The method for obtaining fragrance concentration information includes the following steps:

[0159] Step S600: Obtain fragrance release time information and fragrance release speed information.

[0160] Among them, the fragrance release time information refers to the length of time from the start of the in-vehicle fragrance release to the acquisition of fragrance concentration information, which is detected by a timer and uploaded to the vehicle's central control system. The fragrance release speed information refers to the quantity released by the in-vehicle fragrance device per unit time, that is, the speed corresponding to the fragrance release speed information is equal to the speed corresponding to the fragrance evaporation speed information.

[0161] Step S601: Calculate the product between the time corresponding to the fragrance release time information and the speed corresponding to the fragrance release speed information, and define the calculated product as the fragrance release amount information.

[0162] Among them, the fragrance release amount information refers to the total amount of fragrance released by the in-vehicle fragrance device. It is obtained by the car's central control system calling the fragrance release time information and fragrance release speed information, and calculating the product between the time corresponding to the fragrance release time information and the speed corresponding to the fragrance release speed information.

[0163] Step S602: Determine the fragrance uniformity time information based on the release rate corresponding to the fragrance release rate information and the volume corresponding to the preset vehicle interior volume information.

[0164] Among them, the vehicle interior volume information refers to the volume of the vehicle compartment. The specific value is set by those skilled in the art based on actual conditions and will not be elaborated here. The fragrance uniformity time information refers to the time value in which the fragrance is evenly distributed throughout the vehicle compartment corresponding to the vehicle interior volume information at the release rate corresponding to the fragrance release speed information. It is determined by the vehicle's central control system after analyzing the fragrance release speed information and the vehicle interior volume information. The analysis method is as follows: when the vehicle interior volume information is constant, the larger the speed value corresponding to the fragrance release speed information, the smaller the time value corresponding to the fragrance uniformity time information.

[0165] Step S603: Determine whether the fragrance release time information is greater than the fragrance uniformity time information.

[0166] Specifically, by determining whether the time value corresponding to the fragrance release time information is greater than the time value corresponding to the fragrance uniformity time information, it can be determined that the fragrance release has evenly filled the carriage.

[0167] Step S6031: If it is not greater than, then analyze the volume corresponding to the preset single seat volume information, the leakage rate corresponding to the preset leakage rate information, the release time corresponding to the fragrance release time information, and the fragrance release amount corresponding to the fragrance release amount information to determine the fragrance concentration information.

[0168] The single-seat volume information refers to the volume of a single seat inside the vehicle, which can be set by those skilled in the art based on actual conditions and will not be elaborated here. The leakage rate information refers to the rate at which the fragrance naturally leaks into the vehicle cabin, which can be set by those skilled in the art based on actual conditions and will not be elaborated here.

[0169] The fragrance concentration information in this step refers to the fragrance concentration value inside the car when the time value corresponding to the fragrance release time information is not greater than the time value corresponding to the fragrance uniformity time information. It is determined by the car's central control system after analyzing the single-seat volume information, leakage rate information, fragrance release time information, and fragrance release amount information. The specific analysis method is as follows: calculate the product of the leakage rate information and the fragrance release time information to obtain the fragrance leakage amount, calculate the difference between the fragrance release amount information and the fragrance leakage amount to obtain the remaining fragrance amount, and then calculate the quotient of the remaining fragrance amount and the single-seat volume information to obtain the fragrance concentration information.

[0170] Step S6032: If it is greater than the specified value, then analyze the volume corresponding to the vehicle interior volume information, the leakage rate corresponding to the preset leakage rate information, the release time corresponding to the fragrance release time information, and the fragrance release amount corresponding to the fragrance release amount information to determine the fragrance concentration information.

[0171] In this step, the fragrance concentration information refers to the fragrance concentration value inside the vehicle when the time value corresponding to the fragrance release time information is greater than the time value corresponding to the fragrance uniformity time information. This information is obtained by the vehicle's central control system after analyzing the vehicle's internal volume information, leakage rate information, fragrance release time information, and fragrance release amount information. The specific analysis method is as follows: calculate the product of the leakage rate information and the fragrance release time information to obtain the fragrance leakage amount; calculate the difference between the fragrance release amount information and the fragrance leakage amount to obtain the remaining fragrance amount; and then calculate the quotient of the remaining fragrance amount and the vehicle's internal volume information to obtain the fragrance concentration information.

[0172] Reference Figure 7 The method for controlling the fragrance after the car air freshener releases the fragrance also includes a method for controlling the fragrance after the inhalation device absorbs the fragrance, specifically including the following steps:

[0173] Step S700: Obtain the remaining fragrance concentration information for the seat corresponding to the seat with the seat information turned off.

[0174] Among them, the remaining fragrance concentration information refers to the fragrance concentration value remaining within the seat area corresponding to the seat information that is turned off. The car's central control system detects the absorption time, calculates the product of the absorption speed and absorption time to obtain the absorption amount, and then calculates the difference between the fragrance concentration information and the absorption amount to obtain the remaining fragrance concentration information.

[0175] Step S701: Determine whether the remaining fragrance concentration information is less than the preset baseline remaining concentration information.

[0176] The baseline remaining concentration information refers to the maximum fragrance concentration value remaining within the seat area when the inhalation device stops inhaling. This value is set by those skilled in the art based on actual conditions and will not be elaborated here.

[0177] By determining whether the fragrance concentration corresponding to the remaining fragrance concentration information is less than the fragrance concentration corresponding to the baseline remaining concentration information, it is determined whether to stop the inhalation device from continuing to inhale the fragrance.

[0178] Step S7011: If it is not less than, then control the inhalation device to continue absorbing the fragrance at the speed corresponding to the fragrance absorption speed information.

[0179] If the fragrance concentration corresponding to the remaining fragrance concentration information is not less than the fragrance concentration corresponding to the baseline remaining concentration information, it indicates that the fragrance concentration within the seat range corresponding to the closed seat information is still too high. Therefore, the air intake device is controlled to absorb the fragrance at the speed corresponding to the fragrance absorption speed information in order to reduce the fragrance concentration.

[0180] Step S7012: If it is less than, then analyze the personnel reaction information corresponding to the personnel reaction information to determine the comfort fragrance type information.

[0181] Among them, the comfortable fragrance type information refers to the type of fragrance released by the in-vehicle fragrance device that is suitable for the human response information when the fragrance concentration corresponding to the remaining fragrance concentration information is less than the fragrance concentration corresponding to the baseline remaining concentration information. It is obtained by analyzing the human response information called by the car's central control system. The analysis method is as follows: if the human response information corresponds to pressing the temples, a refreshing fragrance, such as lemon and mint, is released to reduce the human's dizziness symptoms.

[0182] Step S702: Control the in-vehicle fragrance device to release the fragrance to the seat corresponding to the closed seat information based on the fragrance type corresponding to the comfort fragrance type information.

[0183] Specifically, after determining the comfort fragrance type information, the vehicle fragrance device is controlled to release the fragrance corresponding to the comfort fragrance type information to the seat corresponding to the closed seat information, so that people feel more comfortable in the fragrance environment.
