This embodiment is based on the technical solution of the present invention and provides a detailed implementation method and specific operation process, but the scope of protection of the present invention is not limited to the following embodiments.

[0020] The overall implementation scheme of the present invention is divided into the following steps.

[0021] like Figure 6, the whole vehicle controller receives, processes and transmits the fragrance state and demand signal, on the one hand, drives the air conditioner controller to control the air volume and air direction in a specific scene, and on the other hand, drives the combined fragrance generator device to realize fragrance control in multiple scenes (such as self-diffusion without wind and customized diffusion with wind); at the same time, it supports setting fragrance type custom renaming and resetting time on the car screen, can choose to start or close the default fragrance when getting on the car, supports default fragrance switching and special scene customized fragrance, air ventilation time setting and fragrance concentration high, medium and low three gear settings when the fragrance is turned on.

[0022] As Figure 1 and Figure 2 In the fragrance generator device, region I is composed of a cover plate 1, region I is the main action area of the fragrance self-diffusion function, and the mixed fragrance air is blown out to the fragrance outlet through the self-contained blowing assembly (such as a fan); region II is composed of a main body 2, region II is the storage area of the fragrance stick device in the fragrance generator device, which has sealing property, and the main body 2 has three independent spaces inside to store three fragrance sticks, and a driving assembly is arranged on the main body 2, which can push the fragrance sticks to region I and region III as needed; region III is the area after the fragrance generator device is assembled to the air conditioner box inlet pipe channel, and the mixed fragrance air is diffused to the air outlets of the air conditioner through air inlet circulation, realizing the function of customized diffusion with wind.

[0023] In the embodiment of the present application, the fragrance stick has a self-contained identification chip, and the fragrance stick device can be replaced as a whole or the fragrance stick inside the device can be replaced, the whole fragrance stick device can be replaced by identifying the fragrance type through the self-contained chip, and after replacing the fragrance stick inside the device, the user can customize the fragrance type on the car screen.

[0024] In the embodiment of the present application, the fragrance generator device can realize the following fragrance use scenarios. Specifically, in the embodiment of the present application, a vehicle-mounted fragrance control method is provided, which comprises: S101, obtaining the current vehicle state and / or driver state; S102, identifying the fragrance use scenario according to the current vehicle state and / or driver state; S103, determining the target working gear and target working mode of the fragrance generator device according to the fragrance use scenario; S104, controlling the fragrance generator device to cut into the target working gear and work in the target working mode; The fragrance generator device comprises a first working gear and a second working gear; When the target working gear is the first working gear, the fragrance emitted by the fragrance generator device is diffused into the passenger compartment by air conditioner circulating air; When the target working gear is the second working gear, the fragrance generator device blows fragrance out of the fragrance outlet 7 by means of the blowing assembly carried by the fragrance generator device.

[0025] In the embodiments of the present application, as Figure 3 After the vehicle is unlocked or a right door opening signal is sent, the air conditioning ventilation function is triggered, and if the fragrance setting of the vehicle terminal is set as the default opening state after power-on, the fragrance use scenario is identified as the first preset scenario.

[0026] According to user settings, the fragrance function is adjusted to the default opening or closing after power-on.

[0027] At this time, the synchronous driving fragrance generator device pushes the fragrance stick with the default fragrance setting out to region III, so that the fragrance is quickly spread throughout the vehicle under the action of the air conditioning circulating air. The ventilation time is 5 seconds (the vehicle ventilation time can be set to 3-10 seconds according to different vehicle models). After the ventilation after power-on, the air conditioning returns to the memory state before the last power-off, and the fragrance generator device retracts the fragrance stick device to region II after 10 seconds to ensure continuous use of the fragrance. That is, if the fragrance use scenario is the first preset scenario, the target working gear of the fragrance generator device is determined to be the first preset gear, the target working mode of the fragrance generator device is determined to be the working mode of continuously staying in the first preset gear, and the staying time of the generator device in the first preset gear is determined according to the continuous time of the air conditioning ventilation function.

[0028] After the ventilation, the air conditioning state before the last power-off is judged, and the following strategies are executed until the vehicle is powered off or the fragrance function of the vehicle terminal is actively closed, and then the fragrance generator control device drives the fragrance stick device to retract to region II.

[0029] If the air conditioning state before the last power-off is the opening state, the air conditioning keeps the state before the last power-off (consistent with the air volume, air direction, mode and temperature), and continuously ventilates, and simultaneously: The strategy is executed: the combined fragrance generator control device is driven, the default fragrance stick device is pushed out to region III every X1, and is retracted to region II after X2. ①The current air conditioning wind gear ≤ 3 gears When the vehicle terminal sets the fragrance concentration to high: X1=1 minute, X2=30 seconds When the vehicle terminal sets the fragrance concentration to medium: X1=1 minute, X2=20 seconds When the vehicle terminal sets the fragrance concentration to low: X1=1 minute, X2=10 seconds ②The current air conditioning wind gear is greater than 3 gears When the vehicle terminal sets the fragrance concentration to high: X1=3 minutes, X2=30 seconds When the vehicle terminal sets the fragrance concentration to medium: X1=3 minutes, X2=20 seconds When the car machine sets the fragrance concentration to low: X1 = 3 minutes, X2 = 10 seconds.

[0030] That is, after the first preset scene exits, if the air conditioning state of the vehicle before the last power-off is an open state, the fragrance use scene is identified as the second preset scene. If the fragrance use scene is the second preset scene, the target working gear of the fragrance generator device is determined to be the first preset gear, the target working mode of the fragrance generator device is determined to be a working mode of repeatedly switching between the first preset gear and the off gear, and the residence time of the fragrance generator device in the first preset gear and the off gear is adjusted according to the air conditioning wind gear and the fragrance concentration. The step of adjusting the residence time of the fragrance generator device in the first preset gear and the off gear according to the air conditioning wind gear and the fragrance concentration includes: determining the residence time of the fragrance generator device in the first preset gear and the off gear according to a corresponding relationship table of the air conditioning wind gear, the fragrance concentration, the residence time of the first preset gear and the off gear, and the residence time of the first preset gear and the off gear.

[0031] If the air conditioning state before the last power-off is off, the strategy is executed: drive the combined fragrance generator control device, push the default fragrance stick device out to area I every 3 minutes, drive the rear cover fan at the same time, blow the fragrance out of the fragrance outlet, and the fan speed r satisfies the following strategy: When the car machine sets the fragrance concentration to high: speed r = 5000 rpm When the car machine sets the fragrance concentration to medium: speed r = 3500 rpm When the car machine sets the fragrance concentration to low: speed r = 2500 rpm After 10s, the fan of the fragrance rear cover is retracted and closed; The time X1 and X2 in the above strategy are variable parameter values, which can be calibrated to specific values according to the vehicle model. X1 can be selected from 1-60 minutes, and X2 can be selected from 5-60 seconds.

[0032] That is, after the first preset scene exits, if the air conditioning state of the vehicle before the last power-off is the off state, the fragrance use scene is identified as the third preset scene. If the fragrance use scene is the third preset scene, the target working gear of the fragrance generator device is determined to be the second preset gear, the target working mode of the fragrance generator device is determined to be a working mode of repeatedly switching between the second preset gear and the off gear, and the residence time of the fragrance generator device in the second preset gear and the off gear is adjusted according to the fragrance concentration. The step of adjusting the residence time of the fragrance generator device in the second preset gear and the off gear according to the fragrance concentration includes: determining the residence time of the fragrance generator device in the second preset gear and the off gear according to a correspondence table of the fragrance concentration, the residence time of the second preset gear and the off gear, and the residence time of the fragrance generator device in the second preset gear and the off gear.

[0033] As Figure 4 , after the vehicle end receives the fragrance opening signal, the signal is input to the vehicle controller and is synchronously transmitted to the combined fragrance generator control device to set the currently selected fragrance type to the default fragrance type. The vehicle judges the air conditioning state and performs the following operations until the vehicle is powered off or the vehicle actively closes the fragrance function, and then drives the combined fragrance generator control device to retract the fragrance stick device to area II: (1) If it is in the on state, the air conditioner keeps the state before the last power-off (the air volume, air direction, mode and temperature are consistent), and continues to ventilate, and at the same time: The execution strategy is to drive the combined fragrance generator control device to push the default fragrance stick device out to area III every X1 minutes, and retract it after X2 minutes. ① The current air conditioning damper position is less than or equal to 3 gears When the vehicle sets the fragrance concentration to high: X1=1 minute, X2=30 seconds When the vehicle sets the fragrance concentration to medium: X1=1 minute, X2=20 seconds When the vehicle sets the fragrance concentration to low: X1=1 minute, X2=10 seconds When the vehicle sets the fragrance concentration to high: X1=3 minutes, X2=30 seconds When the vehicle sets the fragrance concentration to medium: X1=3 minutes, X2=20 seconds When the vehicle sets the fragrance concentration to low: X1=3 minutes, X2=10 seconds (2) If it is in the off state, The execution strategy is to drive the combined fragrance generator control device to push the default fragrance stick device out to area I every 3 minutes, and drive the rear cover fan to blow the fragrance out of the fragrance outlet. The fan speed r satisfies the following strategy: When the vehicle sets the fragrance concentration to high: speed r=5000 rpm When the car machine sets the fragrance concentration to medium: rotating speed r = 3500 rpm When the car machine sets the fragrance concentration to low: rotating speed r = 2500 rpm The fan is retracted and the fragrance cover is closed after 10s; The time X1 and X2 in the above strategy are variable parameter values, and specific values can be calibrated according to the vehicle model. X1 can be selected from 1-60 minutes, and X2 can be selected from 5-60 seconds.

[0034] That is, when the fragrance function is the default power-on off, if the vehicle receives the user's opening of the fragrance function during driving and the air conditioner is in the on state, the fragrance scene is identified as the fifth preset scene; When the fragrance function is the default power-on off, if the vehicle receives the user's opening of the fragrance function during driving and the air conditioner is in the off state, the fragrance scene is identified as the sixth preset scene. If the fragrance use scene is the fifth preset scene, the target working gear of the fragrance generator device is determined to be the first preset gear, the target working mode of the fragrance generator device is determined to be the working mode of repeatedly switching between the first preset gear and the off gear, and the respective residence time of the fragrance generator device in the first preset gear and the off gear is adjusted according to the air conditioner wind gear and the fragrance concentration. The step of adjusting the respective residence time of the fragrance generator device in the first preset gear and the off gear according to the air conditioner wind gear and the fragrance concentration comprises: determining the respective residence time of the fragrance generator device in the first preset gear and the off gear according to a pre-calibrated corresponding relationship table of the air conditioner wind gear, the fragrance concentration, the respective residence time of the first preset gear and the off gear.

[0035] If the fragrance use scene is the sixth preset scene, the target working gear of the fragrance generator device is determined to be the first preset gear, the target working mode of the fragrance generator device is determined to be the working mode of repeatedly switching between the first preset gear and the off gear, and the respective residence time of the fragrance generator device in the first preset gear and the off gear is adjusted according to the fragrance concentration.

[0036] The step of adjusting the respective residence time of the fragrance generator device in the second preset gear and the off gear according to the fragrance concentration comprises: According to a pre-calibrated corresponding relationship table of the fragrance concentration, the respective residence time of the second preset gear and the off gear, the respective residence time of the fragrance generator device in the second preset gear and the off gear is determined.

[0037] For example, Figure 4The vehicle machine end inputs the replacement fragrance type and fragrance concentration level signal and transmits the signal to the vehicle controller for processing. The vehicle machine end executes the steps in the fifth preset scene and the sixth preset scene until the vehicle is powered off or the vehicle machine end actively closes the fragrance function. Then, the combined fragrance generator control device retracts the fragrance stick device to area II.

[0038] As Figure 5 When the vehicle camera and infrared sensor detect that the driver is not paying attention, yawns, closes his eyes, and is tired or sleepy, the vehicle machine end inputs the signal to the vehicle controller to execute the anti-fatigue reminder. First, the vehicle voice reminds the driver to pay attention and prompts the in-vehicle user that the main driver's exclusive fragrance has been temporarily turned on. At the same time, it is detected whether the combined fragrance generator control device is equipped with fatigue exclusive fragrance. If not, the vehicle voice reminds the user that there is no fatigue reminder fragrance, please replenish in time (this reminder can be set to remind once every time the vehicle is powered on). If so, the strategy is executed: drive the combined fragrance generator control device to push the fatigue reminder fragrance stick device to area III: control the in-vehicle air conditioner to open the left front two air outlets and turn on the air conditioning ventilation function. After 10s, the fragrance stick is retracted and the air conditioner is set to the front state (if the air conditioner was off before, turn off the air conditioner; if the air conditioner was on before, keep the air conditioner parameters such as air speed, air outlet, air speed and temperature the same as before).

[0039] That is to say, during the driving process of the vehicle and when the driver is in a fatigue state, the fragrance scene is identified as the fourth preset scene. If the fragrance use scene is the fourth preset scene, the target working position of the fragrance generator device is determined to be the first preset position, the target working mode of the fragrance generator device is determined to be the working mode of continuously staying at the first preset position, and the staying time of the fragrance generator device at the first preset position is determined according to the duration of the driver being in a fatigue state.

[0040] In the fourth preset scene, it is detected whether the fatigue exclusive fragrance pre-marked in the fragrance generator device is equipped; if the fatigue exclusive fragrance pre-marked in the fragrance generator device is not equipped, the user is prompted to supplement the fatigue exclusive fragrance.

[0041] In the embodiments of the present application, other customized scenes are also provided, such as game, audio and video, and nap break, and the like, which can be defined by the user at the vehicle machine end, and the vehicle machine input signal is sent to the vehicle controller, and then the combined fragrance generator device is driven to execute the corresponding strategy. That is to say, when the vehicle machine is in a game state, the fragrance scene is identified as the seventh preset scene; when the vehicle machine is in an audio and video playing state, the fragrance scene is identified as the eighth preset scene; and when the occupant is in a nap state, the fragrance scene is identified as the ninth preset scene. If the fragrance use scene is the seventh preset scene, the eighth preset scene or the ninth preset scene, the target working gear of the fragrance generator device is determined according to the opening and closing state of the air conditioner, and the residence time of the fragrance generator device at the target working gear is determined according to the fragrance duration time set by the user in different scenes.

[0042] In the embodiments of the present application, the fragrance system can also be started according to the time set by the user, and the timing push function such as morning start or fragrance surrounding before nap is provided.

[0043] When the user inputs the parameters related to the fragrance control to the vehicle machine, the user can directly control the running state of the fragrance system through voice instructions such as “turn on the fragrance”, “strengthen the fragrance”, “turn on the fresh fragrance” and the like.

[0044] By using the vehicle-mounted fragrance control method provided by the present application, the functions such as active diffusion of fragrance with ventilation when the vehicle is powered on, timing push, push of fragrance in fatigue scene to wake up the driver, voice control push, and push without turning on the air conditioner are met.

[0045] The multi-scene fragrance diffusion mode of the present application supports double-mode fragrance diffusion. In the state that the air conditioner is turned on, the fragrance is quickly diffused to the whole vehicle by using the main air inlet of the air conditioner, a wide coverage range is realized, the diffusion speed of the fragrance is improved, and the perception of the user is improved.

[0046] In the state that the air conditioner is turned off, the fragrance is directly distributed to the fragrance outlet arranged in the central control box area by the fan and the pipeline of the fragrance generator device, so that the fragrance can be effectively diffused when the air conditioner is not turned on.

[0047] No matter what state the air conditioner is in, the fragrance can be effectively diffused, the adaptability and user experience of the fragrance generator device are improved, and the needs of different driving scenes such as long-distance driving and short-distance travel are met, and the comfort is enhanced.

[0048] By designing three cavities for the fragrance generator device, the fragrance stick is of a modular structure, the fragrance stick belt is automatically identified by a chip, and is usually stored in the sealed cabin of the main body. When in use, the specific fragrance stick device is automatically judged according to the scene and is pushed out by an electric control mode, and is retracted after work is completed. The sealed cabin design effectively protects the fragrance, prevents volatilization and failure, prolongs the use time of the fragrance, and ensures the best fragrance effect each time.

[0049] The above method meets the needs of consumers for intelligent, personalized and efficient in-vehicle environment, and has a broad market application prospect.

[0050] In addition, the fragrance stick in the embodiment of the present application can be customized; the fragrance stick is internally provided with a movable clamp, and can be loaded with various types of fragrance stick cores with a diameter of 5-10 mm, supports customizing the fragrance type name of a specific position, and supports user self-customization of the fragrance type.
