Technical Field
[0001] This invention belongs to the field of vehicle-mounted intelligent cockpit and near-field communication technology, and relates to a method and system for NFC fragrance recognition based on vehicle-mounted wireless charging. Background Technology
[0002] With the rapid development of the automotive industry, in-vehicle wireless charging modules and in-vehicle fragrance systems have become mainstream configurations in passenger vehicles, with their adoption rate increasing year by year, providing drivers and passengers with a more comfortable driving experience. NFC (Near Field Communication), as a short-range wireless communication technology, supports secure and fast data transmission between devices within 10 centimeters, and is also gradually being applied to fragrance recognition scenarios in in-vehicle fragrance systems.
[0003] Patent CN220031659U discloses a fragrance system and vehicle, which incorporates an NFC radio frequency module in each fragrance bottle interface and an NFC tag on the fragrance bottle. NFC tag recognition is triggered only when a fragrance bottle is inserted into the interface. This solution only achieves basic information recognition after fragrance insertion, lacking a complete fragrance authentication mechanism and failing to prevent counterfeit fragrance products from entering the market. Furthermore, the NFC radio frequency module needs to be additionally installed within the fragrance bottle carrier, making it impossible to reuse existing vehicle hardware and increasing overall vehicle hardware costs. Patent CN112766436A discloses a fragrance system and its control method, which equips each fragrance chamber with an NFC antenna and embeds an NFC tag in each fragrance unit. The identity information of the fragrance unit is identified through the NFC antenna. This solution requires a separate NFC antenna and matching radio frequency circuit for each fragrance chamber, resulting in high hardware costs and complex system wiring. It also only achieves basic identity recognition after fragrance insertion, lacking a robust anti-counterfeiting authentication and cross-vehicle reuse control mechanism, and failing to guarantee automakers' exclusive supply control of fragrance consumables.
[0004] It is known that the common shortcomings of existing in-vehicle fragrance NFC recognition technology include:
[0005] (1) The NFC recognition module needs to be additionally installed inside the fragrance system. It cannot reuse the in-vehicle wireless charging NFC module that has been widely installed in existing vehicles, resulting in high hardware costs and high system redundancy.
[0006] (2) It can only be identified after the fragrance is inserted into the fragrance system, and cannot realize the control logic of authentication before use, resulting in weak anti-counterfeiting and compliance control capabilities;
[0007] (3) It lacks a sound multi-dimensional legality verification mechanism, and can only read basic product information. It cannot realize full-dimensional anti-counterfeiting control such as chip authorization verification, cross-vehicle reuse control, and validity period verification.
[0008] (4) Without a sound system unlocking and locking closed-loop mechanism, it is easy for unauthorized fragrance access to occur, and the legitimate rights and interests of car manufacturers and users cannot be guaranteed. Summary of the Invention
[0009] This invention provides a method and system for identifying fragrance units based on in-vehicle wireless charging NFC. By relying on the NFC module built into the existing in-vehicle wireless charging module, the method can identify and authenticate fragrance units without the need for additional NFC identification hardware. This reduces the overall vehicle hardware cost while achieving full-dimensional anti-counterfeiting control of fragrance units, preventing counterfeit and illegal fragrance products from entering the market, and improving the user experience.
[0010] To achieve the above objectives, the present invention provides a method for NFC-based in-vehicle wireless charging fragrance recognition, comprising the following steps:
[0011] S1: Obtain the fragrance unit with a built-in passive NFC identification card, place the fragrance unit in the NFC identification area of the vehicle wireless charging module, activate the fragrance unit and establish a near-field communication link through the vehicle wireless charging module, and read the encrypted identity data pre-stored in the passive NFC identification card. The encrypted identity data includes the UID identification code and the compliance code.
[0012] S2: The vehicle wireless charging module calls the locally pre-stored official compliant UID fragrance whitelist, and performs pre-verification between the read UID identification code and the UID fragrance whitelist. If the pre-verification passes, the vehicle wireless charging module synchronously sends the encrypted identity data to the central control cockpit module and the fragrance controller module via the CAN bus.
[0013] S3: The central control cockpit module performs real-time verification of the UID identification code, and the fragrance controller module performs decryption verification of the compliance code. When both the real-time verification and the decryption verification are passed, the fragrance unit is determined to be a legal fragrance unit. The central control cockpit module displays the full information of the fragrance unit and prompts the user to insert the fragrance unit into the fragrance controller module.
[0014] S4: The fragrance controller module monitors the in-place status of the legally inserted fragrance unit in real time through the in-place detector, and sends an in-place confirmation signal to the central control cockpit module after the unit is inserted into place.
[0015] S5: After receiving the presence confirmation signal, the central control cockpit module sends an unlock command to the fragrance controller module. The fragrance controller module responds to the unlock command, unlocks all fragrance driving and adjustment functions under its control, and grants user operation permissions.
[0016] Preferably, in step S1, the passive NFC identification card has a built-in passive NFC chip, and the vehicle wireless charging module emits a 13.56MHz high-frequency radio frequency signal through the built-in NFC module to activate the passive NFC chip and build a near-field communication link in accordance with the ISO14443A near-field communication protocol. The passive NFC chip completes power supply and data interaction through radio frequency induction.
[0017] Preferably, in step S3, the fragrance controller module decrypts and verifies the compliance code, which includes: the fragrance controller module uses a pre-agreed symmetrical decryption rule with the passive NFC identification card to decrypt the compliance code, obtains the decrypted fragrance information, and compares the obtained fragrance information with the locally stored official fragrance parameters one by one to check whether the fragrance information meets the vehicle adaptation parameter standards and whether the passive NFC chip is an officially authorized model.
[0018] Preferably, in step S3, the real-time verification of the UID identification code by the central control cockpit module includes: the central control cockpit module uploads the UID identification code to the cloud backend and verifies whether the UID identification code has an abnormal status. The abnormal status includes, but is not limited to, being reused across vehicles, being marked as expired and scrapped, or being included in the official blacklist.
[0019] Preferably, in step S3, if the real-state verification and / or decryption verification fail, the fragrance unit is determined to be an illegal fragrance unit. The fragrance controller module locks and disables the fragrance driving and adjustment functions, the central control cockpit module displays an illegal fragrance prompt, and blocks the fragrance operation permission. The fragrance controller module has built-in automatic locking rules for all scenes.
[0020] Preferably, any triggering condition for the built-in automatic locking rule of the fragrance controller module includes:
[0021] By monitoring the presence status of the fragrance unit in real time by the presence detector, automatic locking is triggered when the inserted fragrance unit is detected to be pulled out of the fragrance controller module.
[0022] After the fragrance unit passes the verification of real-state verification and decryption verification, the fragrance controller module starts timing. If the in-situ detector does not detect the insertion of the legitimate fragrance unit into the fragrance controller module within a preset time period, automatic locking is triggered.
[0023] The fragrance controller module obtains the lifespan data of the fragrance unit through decryption and combines it with real-time usage statistics to monitor the remaining lifespan of the fragrance unit. When it detects that the remaining lifespan of the fragrance unit has been exhausted, it triggers automatic locking.
[0024] Preferably, the fragrance driving and adjustment functions include start / stop control, air volume adjustment, fragrance switching, and timed start / stop.
[0025] Preferably, the full information includes authentication results, fragrance type, functional attributes, remaining service life, shelf life, brand and model, and production batch.
[0026] Preferably, in step S2, if the pre-verification fails, the vehicle wireless charging module determines that the fragrance unit is an illegal fragrance unit, does not send encrypted identity data to the central control cockpit module and the fragrance controller module, and terminates the entire fragrance recognition and verification process.
[0027] On the other hand, the present invention proposes an in-vehicle wireless charging NFC fragrance recognition system, including a reading module, a pre-verification module, a dual verification module, an in-situ detection module, and an unlocking module, wherein;
[0028] Reading module: Used to acquire the fragrance unit with a built-in passive NFC identification card, place the fragrance unit in the NFC identification area of the vehicle wireless charging module, activate the fragrance unit through the vehicle wireless charging module and establish a near-field communication link, and read the encrypted identity data pre-stored in the passive NFC identification card, the encrypted identity data including UID identification code and compliance code;
[0029] Pre-verification module: The vehicle wireless charging module calls the locally stored official compliant UID fragrance whitelist, and performs pre-verification between the read UID identification code and the UID fragrance whitelist. If the pre-verification is successful, the vehicle wireless charging module synchronously sends the encrypted identity data to the central control cockpit module and the fragrance controller module through the CAN bus.
[0030] Dual verification module: The central control cockpit module performs real-time verification of the UID identification code, and the fragrance controller module performs decryption verification of the compliance code. When both real-time verification and decryption verification are passed, the fragrance unit is determined to be a valid fragrance unit. The central control cockpit module displays the full information of the fragrance unit and prompts the user to insert the fragrance unit into the fragrance controller module.
[0031] In-situ detection module: The fragrance controller module uses an in-situ detector to monitor the in-situ status of the legally inserted fragrance unit in real time, and sends an in-situ confirmation signal to the central control cockpit module after the unit is inserted into place;
[0032] Unlocking module: After the central control cockpit module receives the presence confirmation signal, it sends an unlocking command to the fragrance controller module. The fragrance controller module responds to the unlocking command, unlocks all fragrance driving and adjustment functions under its control, and grants user operation permissions.
[0033] The advantages of this invention over the prior art are:
[0034] This invention provides a method and system for NFC-based fragrance recognition using in-vehicle wireless charging. Utilizing the built-in NFC function of the vehicle's wireless charging module, it reads the encrypted identity data of the fragrance unit and pre-verifies the local UID whitelist. Then, through dual collaborative verification by the central control cockpit module and the fragrance controller module, it determines the legitimacy of the fragrance unit. Only fragrance units that have completed the full-process legal verification and are properly inserted are unlocked for fragrance driving and adjustment functions, ultimately granting access to the system. This method completely eliminates the redundant design of existing technologies that require additional NFC recognition hardware within the fragrance system. It fully reuses existing mass-produced vehicle hardware, significantly reducing overall vehicle hardware costs and system wiring complexity. Simultaneously, it overturns the lagging control logic of existing technologies that require insertion before recognition. Through a closed-loop control process of verification, insertion, and unlocking, it achieves comprehensive anti-counterfeiting control of fragrance units, preventing counterfeit and illegal fragrance products from entering the vehicle system at the source. This effectively protects automakers' exclusive supply control rights for fragrance consumables, while simplifying user operation processes and improving the intelligence and convenience of in-vehicle fragrance use.
[0035] To more clearly illustrate the structural features and effects of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.
[0040] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0041] To achieve the above objectives, embodiments of the present invention provide a method for NFC-based fragrance recognition using in-vehicle wireless charging, referencing... Figure 1 and Figure 2 As shown, it includes the following steps:
[0042] S1: Obtain the fragrance unit with a built-in passive NFC identification card, place the fragrance unit in the NFC identification area of the vehicle wireless charging module, activate the fragrance unit through the vehicle wireless charging module and establish a near-field communication link, and read the encrypted identity data pre-stored in the passive NFC identification card. The encrypted identity data includes the UID identification code and compliance code.
[0043] In this embodiment, the fragrance unit is an in-vehicle fragrance consumable officially adapted by the car manufacturer. It integrates a sealed passive NFC identification card, which contains a passive NFC chip. The passive NFC chip pre-stores encrypted identity data. The encrypted identity data is written to the fragrance unit at the factory and cannot be tampered with by the user. The encrypted identity data includes at least the UID identification code (the unique UID identification code of the fragrance unit) and the compliance code. It can also be expanded to include fragrance-related parameters such as fragrance type code, capacity level, remaining service life, production batch, and shelf life as needed. All data is stored in a non-plaintext encrypted format to avoid data leakage and malicious cracking. The NFC recognition area of the in-vehicle wireless charging module is usually located in the center of the wireless charging panel. The surface is printed with an NFC-specific logo and an anti-slip silicone structure, making it convenient for the driver and passenger to operate accurately with one hand. After placement, the NFC module built into the in-vehicle wireless charging module automatically emits a 13.56MHz high-frequency radio frequency signal. This radio frequency signal can provide inductive power to the passive NFC chip in the fragrance unit. After the passive NFC chip is activated, it completes a two-way handshake with the NFC module of the in-vehicle wireless charging module according to the ISO14443A near-field communication protocol to establish a stable near-field communication link. After the communication link is established, the NFC module of the in-vehicle wireless charging module sends an encrypted data read command to the passive NFC chip. After receiving the command, the passive NFC chip sends back the pre-stored encrypted identity data to the in-vehicle wireless charging module, completing the power supply and data interaction. It features fully reusable in-vehicle wireless charging NFC hardware, eliminating the need for any additional identification devices. Furthermore, it employs passive NFC technology, which eliminates the need for independent power supply to the fragrance unit, significantly reducing the hardware cost of fragrance consumables. The data reading process is also fast and secure, perfectly meeting the convenient usage needs of in-vehicle scenarios.
[0044] S2: The vehicle wireless charging module calls the locally stored official compliant UID fragrance whitelist, and performs pre-verification between the read UID identification code and the UID fragrance whitelist. If the pre-verification is successful, the vehicle wireless charging module synchronously sends the encrypted identity data to the central control cockpit module and the fragrance controller module via the CAN bus.
[0045] In this embodiment, pre-verification is the first legality verification step. Its purpose is to quickly complete the basic legality screening of the fragrance unit through the local official UID fragrance whitelist, directly blocking illegal and counterfeit fragrance units whose UID identification codes are not within the official authorization range. At the same time, it avoids invalid data occupying the vehicle's CAN bus resources, improving verification efficiency. In addition, the UID fragrance whitelist supports OTA upgrades for the whole vehicle, and car manufacturers can add compatible fragrance models and blacklist cracked UID identification codes at any time, which has strong scalability.
[0046] If the UID identification code completely matches any authorized code segment in the UID fragrance whitelist, the pre-verification is deemed successful. The vehicle wireless charging module then simultaneously sends the complete encrypted identity data read through the vehicle's CAN bus to the central control cockpit module and the fragrance controller module, entering the second verification stage. If the UID identification code is not within the authorized code segment range of the UID fragrance whitelist, the pre-verification is deemed unsuccessful. The vehicle wireless charging module directly determines that the fragrance unit is an illegal fragrance unit, does not send any encrypted identity data to the central control cockpit module or the fragrance controller module, immediately terminates the entire fragrance identification and verification process, and simultaneously sends the illegal determination result to the central control cockpit module through the CAN bus. The central control cockpit module then displays an illegal fragrance warning on the central control screen, blocking all operation permissions of the fragrance system.
[0047] For example, the official compliant UID fragrance whitelist pre-stores the UID identification code ranges of three official fragrance series adapted to this car model: Ocean series 00000001-00099999, Forest series 00100000-00199999, and Soothing series 00200000-00299999. If the UID identification code of the fragrance unit is 00012345, it matches the whitelist code range, and the pre-verification passes. If the UID identification code is 00300001, which is not within the whitelist code range, the pre-verification fails, and the process is terminated directly.
[0048] S3: The central control cockpit module performs real-time verification of the UID identification code, and the fragrance controller module performs decryption verification of the compliance code. When both real-time verification and decryption verification are passed, the fragrance unit is determined to be a legitimate fragrance unit. The central control cockpit module displays the full information of the fragrance unit and prompts the user to insert the fragrance unit into the fragrance controller module.
[0049] The central control cockpit module and the fragrance controller module form the second verification stage. They are started simultaneously and verified in parallel without interfering with each other. Through the cloud-based dynamic real-time verification of the central control cockpit module and the local authorized decryption verification of the fragrance controller module, the legality of the fragrance unit is verified in all dimensions. This solves the pain point of existing technologies that can only read basic information and cannot achieve full-dimensional anti-counterfeiting control, and completely prevents cracked, stolen, and expired fragrance units from passing the verification.
[0050] Specifically, in step S3, the fragrance controller module decrypts and verifies the compliance code, including: the fragrance controller module uses a pre-agreed symmetrical decryption rule with the passive NFC identification card to decrypt the compliance code, obtaining the decrypted fragrance information. This information is then compared one by one with the locally stored official fragrance parameters to verify whether the fragrance information conforms to the vehicle's compatibility parameter standards and whether the passive NFC chip is an officially authorized model. The vehicle compatibility parameter standards include information such as fragrance type, capacity, and production batch. The officially authorized passive NFC chip model from the automaker is a customized chip model.
[0051] In step S3, the central control cockpit module performs real-time verification of the UID identification code, including: the central control cockpit module uploads the UID identification code to the cloud backend and verifies whether the UID identification code has an abnormal status. The abnormal status includes, but is not limited to, being reused across vehicles, being marked as expired and scrapped, or being included in the official blacklist.
[0052] The central control cockpit module uploads the UID identification code of the fragrance unit to the car manufacturer's cloud backend via 4G / 5G network to verify the real-time dynamic status of the UID identification code. For example, it checks whether the code is already bound to the VIN code (Vehicle Unique Identifier) of another vehicle. If it is, it is considered to be reused across vehicles and the verification fails. It also checks whether the code is marked as expired or scrapped (e.g., exceeding its shelf life or having exhausted its service life). If it is, the verification fails. Furthermore, it checks whether the code is on the official blacklist (e.g., cracked or counterfeit products). If it is, the verification fails. If none of the above are abnormal, the real-time verification is considered to have passed.
[0053] Only when both the real-world verification and decryption verification are passed will the fragrance unit be finally determined to be an officially legitimate fragrance unit. The central control cockpit module will display the full information of the fragrance unit on the central control display screen and prompt the user through pop-up windows and voice prompts: "Fragrance authentication passed. Please insert the fragrance unit into the fragrance controller module for use." The full information includes authentication results, fragrance type, functional attributes, remaining service life, shelf life, brand, model and production batch.
[0054] If either the real-time verification or the decryption verification fails, or if both fail, the fragrance unit is determined to be an illegal fragrance unit. The fragrance controller module immediately locks all fragrance driving and adjustment functions, and the central control cockpit module displays an illegal fragrance prompt on the central control screen with the corresponding reason (such as "This fragrance is already bound to another vehicle" or "The fragrance has expired"). All operation permissions of the fragrance system are blocked throughout the process. The fragrance controller module has built-in automatic locking rules for all scenarios.
[0055] Furthermore, the fragrance controller module has built-in automatic locking rules for all scenarios, and any triggering condition includes:
[0056] By monitoring the presence status of the fragrance unit in real time by the presence detector, automatic locking is triggered when the inserted fragrance unit is detected to be pulled out of the fragrance controller module.
[0057] After the fragrance unit passes the verification of real-state verification and decryption verification, the fragrance controller module starts timing. If the in-situ detector does not detect the insertion of the legitimate fragrance unit into the fragrance controller module within a preset time period (e.g., 30 minutes), automatic locking is triggered.
[0058] The fragrance controller module obtains the lifespan data of the fragrance unit through decryption and combines it with real-time usage statistics to monitor the remaining lifespan of the fragrance unit. When it detects that the remaining lifespan of the fragrance unit has been exhausted, it triggers automatic locking.
[0059] S4: The fragrance controller module monitors the presence status of legally inserted fragrance units in real time through the presence detector, and sends a presence confirmation signal to the central control cockpit module after the unit is inserted.
[0060] The in-situ detector is at least one of an infrared sensor, a Hall sensor, or a physical contact sensor. Optionally, the fragrance controller module has a built-in fragrance slot. The fragrance unit is inserted into the fragrance slot. The infrared sensor determines whether an object is inserted into the fragrance slot by detecting the infrared light blockage. It can be deployed at both ends of the inner side of the fragrance slot. The Hall sensor can determine the insertion depth and position of the fragrance unit by sensing the magnet built into the tail of the fragrance unit. It can be deployed at the bottom of the fragrance slot. The physical contact sensor can determine whether the fragrance unit is fully inserted by detecting the continuity of the contacts after insertion. It can be deployed at the interface of the fragrance slot.
[0061] S5: After receiving the presence confirmation signal, the central control cockpit module sends an unlock command to the fragrance controller module. The fragrance controller module responds to the unlock command, unlocking all fragrance driving and adjustment functions under its control and granting user operation permissions. The fragrance driving and adjustment functions include start / stop control, air volume adjustment, fragrance switching, and timed start / stop.
[0062] Working Principle: When replacing a new fragrance unit, place it in the NFC recognition area of the existing in-vehicle wireless charging module. The module automatically activates the passive NFC chip of the fragrance unit, reads its encrypted identity data, and completes the first pre-verification of the local UID fragrance whitelist, quickly blocking counterfeit products. After successful pre-verification, the central control module and the fragrance controller module simultaneously perform a second verification. Cloud-based real-time verification handles cross-vehicle reuse, expired products, and blacklist dynamic management, while local decryption verification verifies chip authorization and vehicle compatibility. Only after both verifications pass is the fragrance unit deemed a legitimate product, prompting the user to insert it into the fragrance slot. Once the fragrance controller module detects the legitimate fragrance unit inserted, it unlocks all functions of the fragrance system for normal user use. Simultaneously, a full-scenario automatic locking mechanism covers all scenarios, including fragrance unit removal, verification timeout, and lifespan exhaustion. Each use of the fragrance unit requires a complete re-verification and security control loop.
[0063] In this embodiment, the vehicle's existing in-vehicle wireless charging NFC hardware is fully reused, eliminating the need for any additional identification equipment and significantly reducing the overall vehicle hardware cost. Simultaneously, it overturns the existing technology's delayed control logic of insertion followed by identification, achieving pre-authentication and pre-use anti-counterfeiting control. Through a multi-level verification system, it achieves full-dimensional anti-counterfeiting control of the fragrance unit, completely solving the shortcomings of existing technologies such as high hardware costs, weak anti-counterfeiting control capabilities, and system control vulnerabilities. This not only protects the automaker's exclusive supply control rights over fragrance consumables but also improves the user experience.
[0064] On the other hand, reference Figure 3 As shown, this invention proposes an in-vehicle wireless charging NFC fragrance recognition system, including a reading module, a pre-verification module, a dual verification module, an in-situ detection module, and an unlocking module, wherein;
[0065] Reading module: Used to obtain the fragrance unit with a built-in passive NFC identification card. Place the fragrance unit in the NFC identification area of the vehicle wireless charging module, activate the fragrance unit through the vehicle wireless charging module and establish a near-field communication link. The vehicle wireless charging module reads the encrypted identity data pre-stored in the passive NFC identification card. The encrypted identity data includes the UID identification code and compliance code.
[0066] Pre-verification module: Used by the vehicle wireless charging module to call the locally stored official compliant UID fragrance whitelist, and pre-verify the read UID identification code with the UID fragrance whitelist. If the pre-verification is successful, the vehicle wireless charging module will synchronously send the encrypted identity data to the central control cockpit module and the fragrance controller module through the CAN bus.
[0067] Dual verification module: The central control cockpit module performs real-time verification of the UID identification code, and the fragrance controller module performs decryption verification of the compliance code. When both real-time verification and decryption verification are passed, the fragrance unit is determined to be a legal fragrance unit. The central control cockpit module displays the full information of the fragrance unit and prompts the user to insert the fragrance unit into the fragrance controller module.
[0068] In-place detection module: The fragrance controller module uses an in-place detector to monitor the in-place status of legally inserted fragrance units in real time, and sends an in-place confirmation signal to the central control cockpit module after the unit is inserted.
[0069] Unlocking module: After the central control cockpit module receives the presence confirmation signal, it sends an unlocking command to the fragrance controller module. The fragrance controller module responds to the unlocking command, unlocking all fragrance driving and adjustment functions under its control, and granting user operation permissions.

A system for implementing the method of any one of claims 1-9 based on in-vehicle wireless charging NFC fragrance recognition, characterized in that, It includes a reading module, a pre-verification module, a dual verification module, an in-situ detection module, and an unlocking module, among which; Reading module: Used to acquire the fragrance unit with a built-in passive NFC identification card, place the fragrance unit in the NFC identification area of the vehicle wireless charging module, activate the fragrance unit through the vehicle wireless charging module and establish a near-field communication link, and read the encrypted identity data pre-stored in the passive NFC identification card, the encrypted identity data including UID identification code and compliance code; Pre-verification module: The vehicle wireless charging module calls the locally stored official compliant UID fragrance whitelist, and performs pre-verification between the read UID identification code and the UID fragrance whitelist. If the pre-verification is successful, the vehicle wireless charging module synchronously sends the encrypted identity data to the central control cockpit module and the fragrance controller module through the CAN bus. Dual verification module: The central control cockpit module performs real-time verification of the UID identification code, and the fragrance controller module performs decryption verification of the compliance code. When both real-time verification and decryption verification are passed, the fragrance unit is determined to be a valid fragrance unit. The central control cockpit module displays the full information of the fragrance unit and prompts the user to insert the fragrance unit into the fragrance controller module. In-situ detection module: The fragrance controller module uses an in-situ detector to monitor the in-situ status of the legally inserted fragrance unit in real time, and sends an in-situ confirmation signal to the central control cockpit module after the unit is inserted into place; Unlocking module: After the central control cockpit module receives the presence confirmation signal, it sends an unlocking command to the fragrance controller module. The fragrance controller module responds to the unlocking command, unlocks all fragrance driving and adjustment functions under its control, and grants user operation permissions.
