DETAILED DESCRIPTION

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0024] In view of the above problems, the embodiments of the present invention provide a fragrance control method, device and vehicle, which can achieve uniform control of fragrance in a bus, improve the air experience, and enhance the comfort of the driver and passengers. To facilitate understanding of this embodiment, a fragrance control method disclosed in an embodiment of the present invention is first introduced in detail. This method is applied to the controller of a fragrance control system, and the fragrance control system is configured in a bus. Figure 1 As shown, the method includes the following specific steps: Step S102 , responding to a fragrance activation signal acting on the fragrance control system.

[0025] The fragrance control system includes multiple fragrance mechanisms connected to a controller, located at pre-set locations throughout the bus. A dedicated fragrance control system for buses, the fragrance control system consists of a controller and multiple fragrance mechanisms, which adjust the release of fragrance within the bus and the type of fragrance released based on demand. The fragrance mechanisms, the actuators that release fragrance, can connect to the controller via wired (e.g., CAN bus, serial port) or wireless (e.g., Bluetooth, WiFi) connections. They receive commands from the controller and activate the internal fragrance units. In one embodiment, they can be distributed throughout the bus, installed near vents, under seats, on the roof interior panel, and other locations to ensure even fragrance diffusion. The installation location of the fragrance mechanism can be pre-planned based on the bus model (such as a large bus or a minibus), the interior space layout (such as the passenger area, driving area, and aisle area), and the fragrance diffusion efficiency. For example, a bus can be equipped with a fragrance mechanism on the side of the front driving area, the vent above the middle aisle, and on both sides of the rear passenger area to ensure that the fragrance can cover the entire vehicle and avoid local fragrance being too strong or too weak. In this embodiment of the present invention, each fragrance mechanism includes at least one fragrance unit, and each fragrance unit corresponds to a fragrance block of a certain fragrance type. In this embodiment of the present invention, the fragrance unit is a component that directly carries the fragrance raw materials and realizes the release of fragrance (such as a fragrance box with a heating module or a fan module). Only a fragrance block of one fragrance type is placed in each fragrance unit to ensure that a single fragrance unit releases only a specific fragrance type and avoid the mixing of different fragrance types. Fragrance blocks are solid carriers that carry fragrance ingredients. They can be made by mixing and pressing fragrances (natural or synthetic fragrances) with a molding base material (such as beeswax, resin). Fragrance can be released by heating (low-temperature heating to volatilize the fragrance) or ventilation (blowing with a fan to accelerate the diffusion of the fragrance). Its fragrance type is matched one-to-one with the corresponding fragrance unit.

[0026] In a specific implementation, the fragrance activation signal of the embodiment of the present invention carries the fragrance identifier of the target fragrance. The fragrance identifier is a code or symbol that uniquely identifies the target fragrance, allowing the controller to quickly identify and match the corresponding fragrance unit to avoid fragrance confusion. In one embodiment, this can be a digital code, such as 001 for ocean freshness and 002 for wood sandalwood; or a character identifier, such as SEA or WOOD.

[0027] In the embodiment of the present invention, the controller monitors in real time whether a fragrance activation signal is received, which is triggered externally (such as by a user operation) or internally (such as by a system preset). Upon detecting the signal, the controller parses the signal, extracts the fragrance identifier carried therein, and identifies the fragrance release requirement.

[0028] Step S104 : determining a target fragrance unit containing the target fragrance according to the fragrance identifier, and generating a control instruction for the target fragrance unit.

[0029] Step S106: activating the target fragrance unit based on the control instruction.

[0030] The target fragrance unit is the only fragrance unit that corresponds to the fragrance identifier and can release the target fragrance. After the fragrance identifier identifies the target fragrance unit to be activated, the controller controls its activation. This ensures that the fragrance concentration in the vehicle spreads uniformly throughout the vehicle, avoiding situations where the concentration in areas with first-activated units is too high and the concentration in areas with later-activated units is too low. This also prevents localized fragrance perception bias caused by concentration differences. Furthermore, in this embodiment of the present invention, only fragrance units that fully match the target fragrance are activated, and non-target units are forcibly locked. This prevents the mixing of molecules from different fragrances after the fragrance diffuses throughout the vehicle. Passengers experience a consistent fragrance at any location within the vehicle (e.g., the front, middle, and rear), avoiding a reduced experience caused by localized fragrance conflicts. In one implementation, the target fragrance unit can be determined from the fragrance units that meet the fragrance identifier based on the distribution of the fragrance mechanisms. This not only ensures that all activated fragrance units in the vehicle release the same fragrance but also prevents fragrance concentration.

[0031] In summary, the fragrance control method provided by the embodiment of the present invention determines the target fragrance unit through fragrance identification, refines the control granularity to the fragrance unit level, and can achieve a technological breakthrough in the uniform release of a single fragrance throughout the vehicle, solving the industry pain point of large-space fragrance control. At the same time, the fragrance control system is equipped with multiple fragrance mechanisms and can be configured with a variety of fragrances, which not only enables multi-unit collaborative work but also meets the diverse needs of users. The embodiment of the present invention upgrades fragrance control from a simple switch to intelligent unified adjustment, expands the application value of the fragrance system, and enhances the personalization and comfort of the user experience.

[0032] Furthermore, based on the above embodiment, the embodiment of the present invention also provides another fragrance control method. Figure 2 A flow chart of an embodiment of the present invention is shown, referring to Figure 2 , the embodiment of the present invention includes the following steps: Step S202 , responding to a fragrance activation signal acting on the fragrance control system.

[0033] In one embodiment, this step is identical to step S102 described above and will not be further described here. Furthermore, the fragrance control system of this embodiment of the present invention is configured with a central control screen, which is communicatively connected to the controller. The central control screen provides the user with a core human-computer interaction interface, facilitating direct user interaction with the fragrance control system.

[0034] The central control screen displays multiple display controls, including a fragrance selection control. A fragrance activation signal can be generated based on touch operations performed on the fragrance selection control on the central control screen. For example, multiple fragrance selection controls are visually presented on the central control screen's display interface, such as through icons, text labels, or drop-down menus. The controls are typically labeled with the fragrance name and a characteristic icon for intuitive user identification. Each control corresponds to a preset fragrance, such as Fresh Ocean or Woody Cedar. When a user (driver or authorized passenger) performs a touch operation (such as a click or long press) on the selection control corresponding to the target fragrance, the operation's validity can be confirmed by capturing parameters such as the operation's location coordinates and duration (e.g., to eliminate accidental quick clicks).

[0035] Furthermore, the display controls also include position controls for the fragrance dispensers. Embodiments of the present invention can also respond to touch operations on the target position control on the central control screen. Based on the touch operations on the target position control, control instructions for the target fragrance dispenser are generated. The position control can be designed based on a bus interior layout diagram, displaying a schematic diagram consistent with the actual vehicle structure on the central control screen, such as the driver's area, front passenger area, middle passenger area, and rear passenger area. Each area corresponds to one or more position controls, each labeled with a symbol indicating the fragrance dispenser's installation location, such as a small fan icon. To release fragrance in a specific area (e.g., only in the front row), the user touches the position control for the corresponding area. The central control screen identifies the touched target position control, interprets its corresponding spatial zone code (e.g., "ZONE-01" for the front row), and associates the device identifiers of all fragrance dispensers within that area.

[0036] Step S204: determining all fragrance units containing the target fragrance according to the fragrance identifier.

[0037] Step S206: Acquire the location information of each fragrance unit from the pre-recorded fragrance location data table.

[0038] The embodiment of the present invention also pre-establishes a fragrance location data table to record in detail the exact location of each fragrance mechanism and its fragrance unit on the bus, so as to determine the specific locations of all fragrance units containing the target fragrance according to the fragrance control requirements.

[0039] When automatically registering the number and scent of fragrances, an embodiment of the present invention pages the installed fragrance mechanism (e.g., via a broadcast data message), determines its corresponding address and value, and then generates a fragrance location data table for the fragrance mechanism. In specific implementations, a paging command is issued to the fragrance mechanism in response to a signal identifying the fragrance mechanism's installation. Furthermore, a response signal is received from the fragrance mechanism in response to the paging command. The controller parses the response signal, including information such as the device ID, and assigns a unique registration address (e.g., a digital code like "Dev-001") to the fragrance mechanism. This address uniquely identifies the fragrance mechanism in subsequent communications. The registration address is then converted into a value message containing further management information, which may include the fragrance mechanism's communication port number, the control zone to which it belongs, and the maximum number of supported fragrance units.

[0040] A fragrance system typically consists of multiple fragrance units, each corresponding to a specific fragrance type. The system uses the fragrance unit's built-in recognition module (such as an RFID tag or optical sensor) to read the fragrance type information of the fragrance type and determine the fragrance type each fragrance unit can release (e.g., "001 - Ocean Fresh"). This fragrance type information is then associated and stored with the fragrance unit's assigned value information, forming a "assignment information - fragrance unit - fragrance type" correspondence. This ensures that the assigned value information can be used to quickly locate the fragrance unit of a specific fragrance type. Furthermore, the assigned value information is associated with the location of the fragrance units within the bus to generate a fragrance unit location data table. In implementation, the fragrance unit's assigned value information is linked to the coordinates of the actual installation location (e.g., the pre-recorded location code "Pos-A01" corresponding to the "front left air vent") to record the physical location of the fragrance unit within the vehicle. Finally, the assignment information, associated fragrance information, and distribution location information of all fragrance mechanisms are integrated to generate a structured fragrance location data table, providing data support for location query and unit screening in the subsequent fragrance control process.

[0041] Among them, the fragrance of the incense block can be of many kinds, and the fragrance of the incense block can be divided based on the dimensions of smell style (such as fresh, woody, floral and fruity, oriental), functional scenes (such as refreshing, soothing and sleep-inducing, space purification), seasonal adaptation (such as summer cool fragrance, winter warm fragrance), etc., and a variety of specific fragrances are derived under each dimension. For example, fresh tones can include ocean freshness, lemon mint, green tea Longjing, etc., and woody tones can include cedar sandalwood, oak moss, white pine, etc., and support the addition of customized fragrances according to customer needs (such as brand-exclusive fragrances and regional fragrances). Correspondingly, Figure 3The following diagram illustrates the architecture of a fragrance control system corresponding to an embodiment of the present invention. Furthermore, all scent blocks adopt uniform physical specifications (e.g., a cylindrical shape with a diameter of 3 cm and a height of 5 cm, or a rectangular block of uniform dimensions) and incorporate standardized identification modules (e.g., a universal RFID tag or an NFC chip with a uniform frequency band). Regardless of the scent type, the blocks can be adapted to any fragrance unit's mounting compartment, eliminating the need for hardware modifications to the fragrance mechanism, thus eliminating physical limitations on scent switching. Each fragrance unit in the fragrance mechanism is capable of adapting to universal scents, without pre-set fixed scents. For example, a fragrance mechanism may contain three fragrance units, initially configured with Ocean Fresh, Woody Sandalwood, and Peach Sweet, respectively. These can be subsequently changed to Cedar, Citrus, or Lavender as needed, without requiring hardware replacement of the fragrance units; only scent identification and registration are required to update the association. When a new block is used up and replaced, the embodiment of the present invention also verifies the replacement's scent type to ensure that the replacement matches the pre-configured scent, thus preventing management failures.

[0042] The fragrance unit's built-in timing module (e.g., a high-precision real-time clock) can record the unit's operating time and parameters. Timing begins the moment the unit starts, updating the current operating time period at a frequency (e.g., every 10 seconds) until the unit stops operating. The start and stop timestamps of each operation are automatically recorded, along with the duration of each operation. The remaining fragrance block in the fragrance unit is then counted, and a fragrance block replacement signal is generated based on the remaining block. Furthermore, if the user replaces the fragrance block after receiving the fragrance block replacement signal, this embodiment of the present invention, in response to receiving the fragrance block installation signal from the fragrance unit, identifies the installed fragrance block and performs a consistency check against the pre-configured fragrance of the fragrance unit. If the consistency check fails, the fragrance unit's operating status is set to disabled. In one embodiment, the display status of the control corresponding to the fragrance unit on the central control screen can be modified. For example, the fragrance mechanism icon on the front right row can be grayed out to indicate that activation is disabled. Alternatively, it can be changed to a flashing red state, accompanied by a pop-up window warning of a fragrance mismatch. In the above embodiment, the identification code of the fragrance block in the fragrance unit can be obtained and compared with the pre-stored fragrance block identification code to determine the fragrance type verification result of the fragrance block. If the preset fragrance type is FR-002 and the actual identification is FR-005, the controller will immediately send an abnormal signal to the central control screen, triggering an alert action.

[0043] In order to meet the diversified needs of customers for different concentrations of fragrance and customized fragrance blocks (such as some customers temporarily need to increase the fragrance concentration in a certain area of ​​the bus, or replace it with an unpreset limited fragrance block), the embodiment of the present invention supports manual registration of the number of fragrances (i.e. the number of fragrance units enabled) and the fragrance of the fragrance blocks. Among them, the embodiment of the present invention also responds to the fragrance configuration signal for the fragrance unit; according to the target fragrance indicated by the fragrance configuration signal, the fragrance configured for the fragrance unit is updated. Among them, the configuration update can be performed through the central control screen, such as setting the fragrance management menu and setting the manual registration-fragrance quantity configuration option for it. The user can select the newly added fragrance unit to be enabled (check through the position control, such as "middle row left fragrance unit" and "back row middle fragrance unit"), enter the registration instruction (such as confirmation password or authorization code), and after receiving the instruction, the controller updates the "enabled fragrance unit list" and adds the assignment information and location information of the newly added unit to the database. After manual registration, the newly added fragrance unit can respond to subsequent fragrance start-up signals, participate in the fragrance release, and adjust the concentration or coverage range. Correspondingly, Figure 4 A flow chart of scent verification is shown.

[0044] Step S208: determining a target fragrance unit based on the location information.

[0045] In summary, the target fragrance unit determined by the embodiment of the present invention satisfies the preset distribution method, and the target fragrance unit to be activated is finally selected from all fragrance units containing the target fragrance, ensuring that the fragrance is evenly covered in the car and the released fragrance is always uniform.

[0046] Furthermore, the fragrance activation signal can also carry information about the target fragrance concentration. This embodiment of the present invention also determines the target number of fragrance units to activate based on this concentration information, and then determines the target fragrance units based on the target number of activations. This further meets the user's personalized needs for fragrance concentration, achieving precise control across both spatial and quantitative dimensions.

[0047] The fragrance activation signal may carry parameters that represent the intensity of the fragrance that the user expects in the car, such as level 1 light fragrance, level 2 standard fragrance, level 3 strong fragrance, or fragrance molecule concentration of 200-500mg / m 3This specific numerical parameter can be used to calculate the total number of target fragrance units to be activated based on the corresponding concentration information. For example, level 1 light fragrance corresponds to 2 activated fragrance units, and level 2 standard fragrance corresponds to 4 activated fragrance units, ensuring that the number of activated units matches the desired concentration. Furthermore, the final distribution position of the target fragrance units is determined based on the bus's spatial structure (such as length, seat layout, and ventilation path) to ensure that the activated fragrance units can evenly cover the entire bus and avoid local concentrations that are too high or too low. For example, distribution methods such as front-to-back symmetrical distribution, full regional coverage distribution, and uniform distribution along the ventilation openings can be adopted.

[0048] Step S210: Generate a control instruction for the target fragrance unit.

[0049] Step S212: activating the target fragrance unit based on the control instruction.

[0050] After identifying the target fragrance units, the controller generates control instructions for these target fragrance units. These instructions contain various information, such as the target fragrance unit's identifier (used to accurately point to the corresponding unit), a start signal (instructing the unit to begin operation), and a release intensity parameter (adjusting the intensity of the fragrance release as needed). Furthermore, the generated control instructions are sent to each target fragrance unit. Upon receiving the instructions, the target fragrance unit activates operation according to the instructions. For example, the heating device inside the fragrance unit begins heating, causing the fragrance substance to volatilize, or the fan starts, blowing the volatilized fragrance into the vehicle, creating a comfortable in-vehicle fragrance environment for passengers.

[0051] Among them, the fragrance control system can also be connected to the user terminal for communication. The user can initiate a fragrance control request (such as selecting a fragrance, setting a concentration, and specifying an area) through the APP interface of the user terminal (such as a mobile phone or other electronic device), thereby realizing remote operation control.

[0052] Furthermore, fragrance control can be implemented based on the vehicle's air conditioning ducts. Distributed fragrance units (e.g., 2-7, scalable) can be embedded in the vehicle's air conditioning duct nodes (such as the front air conditioning outlet duct, the rear independent air conditioning duct, the roof duct, etc.). This allows the fragrance molecules generated by the fragrance units to directly enter the air conditioning ducts, where the airflow of the air conditioning system creates a fragrance cycle. Furthermore, the control parameters of the fragrance units (e.g., number of activations, volatilization intensity) can be dynamically adjusted based on the vehicle's air conditioning operating status, creating scenario-based, linked control.

[0053] In summary, the embodiments of the present invention distribute the fragrance units at preset positions in the vehicle, or at key nodes in the air-conditioning duct, and combine the independent regulation of each fragrance unit by the controller. This allows the fragrance concentration and fragrance experience to be consistent in the front driving area, the middle passenger area, and the rear corners of the bus, completely resolving the pain point of uneven fragrance coverage in large-space vehicles and creating a comfortable and unified olfactory environment for passengers.

[0054] Furthermore, based on the above embodiment, an embodiment of the present invention further provides a fragrance control device, which is applied to a controller of a fragrance control system, and the fragrance control system is configured in a passenger vehicle; Figure 5 A schematic diagram showing the structure of an embodiment of the present invention is shown.
