[0057] The fragrance control unit 20 is in communication connection with the master control unit 10 and the fragrance device 30, the fragrance control unit 20 can receive upper-level control instructions from the master control unit 10, and can read and record fragrance information of the fragrance device 30, the fragrance control unit 20 is used to send lower-level control instructions to the fragrance device 30, so that the fragrance device 30 can respond to the upper-level control instructions of the master control unit 10, and make corresponding response actions according to the fragrance information, so as to present different fragrance modes in the vehicle interior, and adjust the odor in the vehicle interior to meet the odor adjusting needs of the vehicle user;

[0058] For example, the fragrance mode includes a general fragrance mode, a refreshing mode and an odor adjustment mode.

[0059] In the general fragrance mode, the user can set the fragrance type, fragrance concentration and fragrance duration by issuing control instructions.

[0060] In the refreshing mode, the system is automatically started intelligently, of course, the user can also set the fragrance type, fragrance concentration and fragrance duration to enter the refreshing mode, through the refreshing mode, the user can be refreshed and the brain can be refreshed.

[0061] In the odor adjustment mode, the user can set the fragrance type, fragrance concentration and fragrance duration by issuing control instructions when the user smells an odor in the vehicle interior space. The fragrance device 30 is installed on the vehicle and is in communication connection with the fragrance control unit 20, the fragrance device 30 stores different types of fragrance sources and fragrance information of the fragrance sources, and the fragrance device is used to execute lower-level control instructions from the fragrance control unit 20 to realize different fragrance modes;

[0062] Exemplarily, the different types of fragrance sources refer to that the fragrance sources have different fragrance types, and of course, different types (such as liquid, solid) of fragrance sources can be put in accordance with user preferences.

[0063] Exemplarily, the fragrance device 30 includes a fragrance storage unit for storing fragrance sources and a diffusion unit, the fragrance sources can be in the form of solid, liquid, etc., and the diffusion unit can adopt a fan, the rotation speed of the fan can be controlled by the fragrance control unit 20, thereby adjusting the fragrance concentration.

[0064] Exemplarily, the fragrance concentration includes three levels of low concentration, high concentration and highest concentration, and of course, other levels can also be set, which is not limited in this example.

[0065] Exemplarily, the fragrance information can include: fragrance type, fragrance remaining amount, fragrance available time, fragrance corresponding ambient light color, etc. The ambient light control unit 40 is in communication connection with the main control unit 10 and the ambient light device 50, the ambient light control unit 40 can receive the upper control instruction from the main control unit 10 and send the lower control instruction to the ambient light device 50, so that the ambient light device 50 can respond to the upper control instruction of the main control unit 10 and cooperate with the fragrance device 30 to realize different ambient light modes in linkage with the fragrance device 30.

[0066] The ambient light device 50 is located on the vehicle and is in communication connection with the ambient light control unit 40, the ambient light device 50 includes an instrument panel ambient light 51, a secondary instrument panel ambient light 52, a front-row door ambient light 53 and a rear-row door ambient light 54, the ambient light device 50 can be linked with the fragrance device 30 to light different ambient lights according to the lower control instruction sent by the ambient light control unit 40, thereby realizing different ambient light modes.

[0067] Exemplarily, the ambient light mode includes a general ambient light mode and a wake-up ambient light mode, the general ambient light mode corresponds to a general fragrance mode and an odor adjustment mode in the fragrance mode, in the general ambient light mode, the instrument panel ambient light 51 lights up the color corresponding to the fragrance type, and has a brightness Q1, then the secondary instrument panel ambient light 52, the front-row door ambient light 53 and the rear-row door ambient light 54 light up the color corresponding to the fragrance type in turn at a certain time interval T1, and have a brightness Q2, after all the ambient lights of the ambient light device 50 are lit up, the ambient light device 50 is extinguished after a certain time interval T2, through the lighting in turn, the user can visually perceive the release of the fragrance, thereby improving the use experience.

[0068] In an example, T1 is set to 0.5s.

[0069] In an example, T2 is set to 1min.

[0070] In an example, Q1=Q2.

[0071] For example, when different fragrance sources are selected, the ambient lighting device 50 uses different colors. For instance, when a rose fragrance source is selected, all ambient lights use a rose red color. Of course, the dashboard ambient light 51, the secondary instrument panel ambient light 52, the front door ambient light 53, and the rear door ambient light 54 can each be adjusted to have different colors.

[0072] The Awakening Ambient Lighting mode corresponds to the Awakening mode in the Fragrance mode. In the Awakening Ambient Lighting mode, the dashboard ambient light 51 is lit first, stays on, and has a brightness of Q3. Then, the secondary instrument panel ambient light 52, the front door ambient light 53, and the rear door ambient light 54 are lit sequentially at intervals of a certain duration T3, stay on, and have a brightness of Q4. After all the ambient light devices 50 are lit, after a certain duration T4, the ambient light devices 50 are turned off.

[0073] For example, T3≤T1, T4≥T2, and in particular, T3<T1, T4>T2. By shortening the duration of sequential lighting of the ambient light devices 50 and increasing the lighting duration and rhythmic duration of the ambient light devices 50, it is possible to remind users to pay attention to safe driving and take timely rest.

[0074] For example, Q3 = Q4 ≥ Q1 = Q2.

[0075] For example, in the energizing ambient light mode, the ambient light device 50 uses a striking color, such as bright red or dark green.

[0076] In one example, the fragrance mode also includes a rest mode. In rest mode, the corresponding designated fragrance source in the fragrance device is activated to diffuse a specific fragrance and automatically selects a low concentration. The designated fragrance source can be a brand-related fragrance of the vehicle manufacturer, which brings a unique comfort experience to the user. The designated fragrance source can also be a fragrance set by the user. The user's favorite fragrance can be directly activated through rest mode to enhance the user's personalized experience.

[0077] In this example, the general ambient lighting mode in the ambient lighting mode corresponds to the rest mode. That is, when the rest mode is turned on, the ambient lighting mode will switch to the general ambient lighting mode.

[0078] In one possible example, as shown in the appendix Figure 1 As shown, the main control unit 10 includes control keys 11, which enable human-computer interaction. Users can input commands to the main control unit 10 by operating the control keys 11.

[0079] For example, the control key 11 is arranged on the instrument desk of the vehicle, and the control key 11 can be arranged as a button or a knob, and the user can directly operate the control key 11 on the instrument desk.

[0080] As shown in the accompanying drawings, Figure 2 The control key 11 includes an opening / closing 111 key position, a mode selection 112, and a fragrance selection 113, etc. By operating the opening / closing 111 key position, the opening or closing of the odor adjusting system can be realized. In an example, when the control key 11 is a button, it can be set as opening by pressing once and closing by pressing twice. When the control key 11 is a knob, it can be set as opening by rotating to a certain angle and closing by resetting. By operating the mode selection 112 key position, the fragrance mode of the odor adjusting system can be quickly selected. By operating the fragrance selection 113 key position, the user can quickly select the desired fragrance, which has strong interaction and is convenient for the user to adjust personally, and can bring good use experience to the user.

[0081] For example, the main control unit 10 further includes a memory unit, which can memorize the last setting of the user before power off, and automatically start the last setting of the user after the next system power on.

[0082] In a possible example, as shown in the accompanying drawings, Figure 3 The vehicle odor adjusting system further includes a display unit 60, which is used to display the fragrance information and the fragrance mode.

[0083] The display unit 60 is in communication connection with the fragrance control unit 20, the fragrance control unit 20 can send the read fragrance information of the fragrance device 30 to the display unit 60, the display unit 60 can display the fragrance information in real time, the fragrance control unit 20 can send the received superior control instruction from the main control unit 10 to the display unit 60, and the display unit 60 can display the current fragrance mode according to the information of the superior control instruction. The user can check the fragrance information and the fragrance mode in real time through the display unit 60, and the use experience of the user is ensured.

[0084] In this example, the display unit 60 can also communicate with the main control unit 10 simultaneously. The main control unit 10 can synchronously send the superior control commands sent to the fragrance control unit 20 and the ambient light control unit 40 to the display unit 60. The display unit 60 can display the current fragrance information, fragrance mode, and ambient light mode according to the received superior control commands. The control key 11 is set on at least one of the dashboard and the display unit 60. When it is set on the dashboard, as mentioned above, it will not be repeated here. When it is set on the display unit 60, it can be implemented through the display unit 60. The user can directly complete the interaction on the display unit 60, input commands through the control key 11, and then the main control unit 10 converts the commands into superior control commands and sends them to the fragrance control unit 20, thereby realizing the selection of the fragrance mode.

[0085] In this example, the display unit 60 can be a mobile phone screen, a tablet screen, etc., and can establish a communication connection with the fragrance control unit 20 via Bluetooth, WIFI, etc., so that users can view fragrance information and fragrance modes in real time, which is more convenient.

[0086] In this example, the display unit 60 is mounted on the vehicle and can be configured as the vehicle's central control screen.

[0087] In one possible example, as shown in the appendix Figure 4 As shown, the display unit 60 is communicatively connected to the main control unit 10. The main control unit 10 synchronously sends the communication information with the fragrance control unit 20 and the ambient light control unit 40 to the display unit 60. The display unit 60 can display fragrance information, fragrance mode, ambient light mode and other information in real time. At this time, the central control unit 10 realizes the communication control of the entire system.

[0088] In this example, control key 11 may be located on the dashboard or on the display unit 60.

[0089] In this example, the display unit 60 can be a mobile phone screen, a tablet screen, etc., and can establish a communication connection with the main control unit 10 via Bluetooth, WIFI, etc., so that users can view fragrance information and fragrance modes in real time, which is more convenient.

[0090] In this example, the display unit 60 can also be installed in a vehicle, using the vehicle's central control screen.

[0091] For example, when the control keys 11 are arranged on the display unit 60, the on / off 111 key has the first priority, the mode selection 112 key has the second priority, and the fragrance type selection 113 key has the third priority. That is, when the display unit 60 is powered on, the display unit 60 displays a first interface on which the on / off 111 key is displayed. When the user operates the on / off key to turn on the odor adjusting system, the display unit 60 jumps to a second interface on which the mode selection 112 key is displayed. When the user operates the mode selection 112 key, the display unit 60 jumps to a third interface on which fragrance modes, such as a general fragrance mode, an invigorating mode, an odor adjustment mode, and a rest mode, are displayed. After the user selects a mode, the display unit 60 jumps to a fourth interface on which the fragrance type selection 113 key is displayed for the user to select a desired fragrance type.

[0092] It can be understood that each interface of the display unit 60 is provided with a return key to facilitate the user to return to the previous interface for other operations.

[0093] For example, on the third interface, in addition to the fragrance type key, fragrance information is also displayed. Optionally, the fragrance type selection 113 key can be set as an icon corresponding to the fragrance type, such as a rose pattern for a rose fragrance type. Optionally, the fragrance type key can be hollow and filled with a color inside to correspond to the remaining amount and available time of the fragrance source. Optionally, the color filled inside the fragrance type key can be associated with the color of the atmosphere lamp.

[0094] Optionally, the fragrance remaining amount can also be displayed in the form of a pop-up window. When the fragrance remaining amount is less than 10%, the remaining amount pop-up window reminds the user when the user enters the third interface of the display unit 60. To improve the user experience and reduce the user's hunger, the remaining amount pop-up window appears only once after the first power-on, that is, the remaining amount pop-up window appears only when the user enters the third interface for the first time after turning on the odor adjusting system.

[0095] In another example, the control keys 11 further include a rest mode key. The rest mode key has the second priority, that is, in addition to the mode selection 112 key, the rest mode key is also displayed on the second interface of the display unit 60. The user can directly enter the rest mode by operating the rest mode key to increase the brand effect of the vehicle manufacturer. If the fragrance device 30 does not install a brand fragrance, the display unit 60 displays a pop-up window to remind the user that the brand fragrance is not installed, or when the brand fragrance is insufficient, the pop-up window reminds the user that the brand fragrance is insufficient.

[0096] Optionally, the control key 11 further comprises a rest setting key position, which is in communication connection with the main control unit 10 or the fragrance control unit 20, and can obtain the fragrance source installed in the fragrance device 30, so as to set the fragrance type corresponding to the rest mode by the user, and improve the personalized experience of the user.

[0097] Optionally, when the display unit 60 pops up the pop-up window of the brand fragrance not installed, the rest setting key position can be displayed on the pop-up window page and associated, so as to set the fragrance type corresponding to the rest mode by the user, and improve the personalized experience of the user.

[0098] In one possible example, as shown in the accompanying Figure 5 The in-vehicle odor adjusting system provided by the present application comprises a voice unit 70, which is in communication connection with the main control unit 10, and is used to receive external voice instructions and send the voice instructions to the main control unit 10, and the main control unit 10 generates upper control instructions according to the received voice instructions.
