Description

In-vehicle air quality control system and method and vehicle

Technical Field

The invention relates to the field of air quality, in particular to an in-vehicle air quality control system, an in-vehicle air quality control method and a vehicle, so that the operation of air conditioning equipment such as windows, air conditioners, air purifiers and the like is controlled according to the in-vehicle air quality condition, and the in-vehicle air quality control is realized.

Background

Due to the long-term development and application of industries such as power generation, metallurgy, petroleum, chemistry, textile printing and dyeing and the like, the exhaust discharged to the atmosphere by various vehicles is continuously accumulated in the running process, and the like, the PM2.5 data of the reactive air quality is seriously out of standard at present, and the negative influence on the health and travel of people is also more and more serious. There has been a great deal of epidemiological evidence that high PM2.5 increases the risk of acute respiratory and cardiovascular diseases, and also may induce chronic diseases such as lung cancer, COPD (chronic obstructive pulmonary disease), cardiovascular and cerebrovascular diseases, etc. This also results in the traditional concept that the practice of ventilation with windows does not necessarily favor the health of people, especially in the case of poor external air quality. That is, in addition to going out, people in the room are also at risk of being exposed to environments with high PM 2.5.

Therefore, people pay attention to air quality data such as PM2.5 on the same day and decide whether to window or not, so that indoor air is prevented from being polluted by outside air. But the method is suitable for indoor environments such as bedrooms and offices, the environmental condition change range of fixed places is small, and indoor people can check outdoor PM2.5 conditions by using mobile phones or computers at any time in working gaps. For the drivers driving, the external environment is different through different areas, for example, power generation industrial equipment is built in some areas, the surrounding air quality is poorer than that of areas without industrial equipment, the traffic jam or vehicles are more, and the concentrated emission of a large amount of vehicle tail gas can also lead to poorer surrounding air quality. That is, the PM2.5 is different for each stretch of travel of the vehicle, and some of the stretch is better than the interior of the vehicle, and some of the stretch is worse than the vehicle.

If the driver looks over the data from time to time, the driver can judge according to the data and actively control the switch of the equipment such as the car window, the air conditioner and the like, thereby being unfavorable for safe driving and easily causing traffic accidents.

In addition, if no professional equipment is used for detection, the air quality inside and outside the vehicle is difficult to judge by the feeling of a driver or the air quality data outside the vehicle. The interior space of the vehicle is smaller than that of bedrooms, offices and the like, and the long-time sealing can cause the increase of the content of harmful gases such as carbon dioxide and the like and the loss of oxygen, especially under the condition of full load or smoking of people in the vehicle. That is, the magnitude and frequency of the change in the air quality of the vehicle interior space is large as compared with the indoor environment where the space is large, and if the driver needs to frequently check data in order to secure the air quality in the vehicle, the air conditioning equipment such as windows, air conditioners, or air purifiers are frequently turned on and off.

In addition to the inability to accurately grasp whether to switch the air conditioning apparatus, and the timing of the switching apparatus, it is also difficult for an average driver to control the setting state of the air conditioning apparatus without expert knowledge in terms of air quality. That is, even if a detector for detecting the air quality in the vehicle is provided in the vehicle, the driver can know the air condition inside and outside the vehicle, and not only the active switching setting is troublesome, but also the ventilation state such as the air-conditioning exhaust speed, the opening of the front window or the rear window, the operating time of the air cleaner, and the like cannot be set well.

As shown in fig. 1 to 5, the present invention provides an in-vehicle air quality control system, method and vehicle, so as to achieve the purpose of actively adjusting and optimizing in-vehicle air by means of air interaction or purification according to the in-vehicle air quality conditions, and to meet the current air quality problem, and to protect the health of in-vehicle personnel.

Specifically, the in-vehicle air quality control system includes a detection module 10 and an equipment control module 20, wherein the detection module 10 detects in-vehicle and out-of-vehicle air quality conditions, acquires in-vehicle air quality information 11 and out-of-vehicle air quality information 12, and the equipment control module 20 controls an air interaction device 100 and/or an air purification device 200 according to the in-vehicle air quality information 11 and the out-of-vehicle air quality information 12, so as to realize in-vehicle air adjustment and even optimization. The air interaction device 100 may be implemented as a device for realizing air adjustment and optimization through air interaction inside and outside a vehicle, such as a vehicle window system and/or an air conditioning system. The air interaction device 100 may be implemented as a vehicle-mounted air cleaner or the like that achieves air conditioning and optimization by purifying air in a vehicle.

The detection module 10 includes an in-vehicle air detection module 13 for detecting the air quality in the vehicle to form the in-vehicle air quality information 11. The in-vehicle air quality information 11 may include, but is not limited to, a PM2.5 value, a PM10 value, whether there is harmful gas, whether the carbon dioxide content is too high, temperature, humidity, and the like. The in-vehicle air detection module 13 may be implemented as one or more of a PM2.5 detector, a PM10 detector, a temperature detector, a humidity detector, a wind speed detector, a cigarette detector, an organic compound detector, etc. to measure in-vehicle air quality data and serve for intelligent control of subsequent devices.

The detection module 10 further includes an off-board air detection module 14 for detecting off-board air quality to form the off-board air quality information 12. The off-board air quality information 12 may include, but is not limited to, PM2.5 values, whether there is harmful gas, whether the carbon dioxide content is too high, temperature, humidity, and the like. The air detection module 14 outside the vehicle may also be implemented as one or more of a PM2.5 detector, a PM10 detector, a temperature detector, a humidity detector, a wind speed detector, a cigarette detector, etc. to measure air quality data outside the vehicle, and serve for intelligent control of subsequent devices.

Preferably, the in-vehicle air detection module 13 and the out-of-vehicle air detection module 14 are implemented as PM2.5 detectors, so that the device control module 20 can control devices according to the in-vehicle PM2.5 values to adjust in-vehicle air. It will be appreciated by those skilled in the art that the in-vehicle air detection module 13 and the out-of-vehicle air detection module 14 may share the same detector or sensor, or may be each independently provided with a corresponding detector or sensor, and the present invention is not limited thereto.

Preferably, in order to make the in-vehicle air quality information 11 more accurate, the in-vehicle air detection module 13 is installed in an air duct of a vehicle, such as an air conditioning duct or a separate detection duct, and samples of air inside and outside the vehicle are extracted for detection, thereby forming the in-vehicle air quality information 11 and the out-vehicle air quality information 12.

Furthermore, the in-vehicle air detection module 13 and/or the off-vehicle air detection module 14 are preferably implemented as a sensor having a water-air separation structure, in particular as a PM2.5 sensor. On one hand, the influence of humidity lower than detection precision is reduced, on the other hand, large particles are filtered, and the service life of the sensor is protected as much as possible.

Specifically, as shown in fig. 6 to 8, the water-gas separation structure 300 of the sensor includes a sample collection device 310, a water-gas separation body 320, and at least one communication device 330, wherein the communication device 330 connects the sample collection device 310 and the water-gas separation body 320, so that the sample collected by the sample collection device 310 can be circulated to the water-gas separation body 320. That is, the sample collection device 310 and the water vapor separation body 320 extend from both ends of the communication device 330, respectively. The communication means 330 may be implemented as a quick connector, a snap-on structure, a screw structure, etc. connection structure. Different quick connectors are selected, and different directions can be changed, so that the universal interface is selected.

The water-gas separation body 320 is used for removing moisture contained in the sample, and isolating the influence of external moisture on the detection of the sensor. The water-gas separation body 320 includes a housing 321, a filter screen 322, and a sealing valve 333, wherein the filter screen 322 is installed in the housing 321, and the sealing valve 333 is installed on a sidewall of the housing 321.

The housing 321 has a filter chamber 3215 with an air inlet 3211 and an air outlet 3212, wherein the filter chamber 3215 communicates with the air inlet 3211 and the air outlet 3212, wherein the air inlet 3211 communicates with the sample collection device 310, and the air outlet 3212 is adapted to connect with the communication device 330 for removing sample gases. The filter screen 322 is mounted to the filter chamber 3215, such as by port snap fit, screw mounting, etc., and the invention is not limited.

That is, the sample gas collected by the sample collection device 310 enters the filter chamber 3215 through the gas inlet 3211, the large particles and the moisture are filtered by the filter screen 322, and the filtered sample gas is discharged through the gas outlet 3212 and transmitted to the detection portion for detection.

The housing 321 may further comprise an outer housing 3213 having the air inlet 3211 and an end housing 3214 having the air outlet 3212, wherein the outer housing 3213 and the end housing 3214 are assembled to form the housing 321, e.g., by snap fit, screw connection, etc. Or the housing 31 may be implemented as a unitary structure, the invention is not limited.

The filter screen 322 has a filter peripheral wall 3221 and at least one filter end wall 3222, wherein the filter peripheral wall 3221 extends from a periphery of the filter end wall 3222 to form a three-dimensional shape, such as a cylinder, defining a filter space. The wall 3221 and the end wall 3222 have a plurality of micro-holes, and when the sample gas passes through the micro-holes, the sample gas interacts with the wall, and water molecules in part of the moisture adhere to the periphery of the micro-holes of the filter screen. When the micropores are under the action of the tension of water, the micropores are sealed and gambed step by step to form a natural seal, so that the influence of external moisture on the detection of PM2.55 sensors and the like is isolated.

Further, the housing 321 has a drainage chamber 3216, wherein the drainage chamber 3216 is disposed below the filter screen 322 and communicates with the filter chamber 3215 for receiving the water blocked and filtered by the filter screen 322. The sealing valve 333 is operatively connected to the drain chamber 3216, and the water in the drain chamber 3216 is affected by gravity, causing the sealing valve 333 to open more and more until the water is completely drained. Preferably, the sealing valve 333 is implemented as an umbrella valve.

Further, the casing 321 protrudes from the periphery of the sealing valve 333 to form a water outlet groove 3217. That is, the sealing valve 333 is attached to the water outlet tank 3217. The water outlet tank 3217 may be adapted to be connected to other channels so as to remove water released by the sealing valve 333.

The principle of operation of the one-way valve will be known to those skilled in the art. When negative pressure is generated in the casing 321 under the action of fan suction, the tightness of the sealing valve 333 is tighter until the sealing valve is completely closed, so that air cannot enter and exit. When the negative pressure is lost, the original state is restored, and if filtered water is in the cavity, the valve body can be opened more and more under the action of water gravity until the water is completely discharged. In addition, since the member is installed in the cab, the artificial door is opened or closed, which will cause instantaneous positive and negative air pressure changes to the air in the vehicle, and will also play a role in opening the sealing valve 333 for drainage. An effective drainage can be obtained.

The sample collection device 310 is operably coupled to the sampling device of the sensor and receives a sample collected by the sampling device. The sampling device may be a device that samples by forming the intake air pressure, etc., and the present invention is not limited thereto. The sample collection device 310 may be implemented as a hose (air tube) having a length of no more than 300mm, so as to avoid excessively long lengths, affecting the intake pressure, and causing measurement accuracy errors such as PM 2.5. Of course, it will be appreciated by those skilled in the art that the sample collection device 310 may also be implemented directly as the air inlet of the water-gas separation body 320, and that a hose is not the only and necessary option.

In another embodiment of the present invention, the off-board air detection module 14 is communicatively connected to the internet to obtain the internet data of the off-board air quality in a localized manner to form the off-board air quality information 12, without the need for additional installation of detection equipment to detect the off-board air quality, thereby reducing costs. Further, the off-board air detection module 14 is operatively connected to the vehicle navigation module, and obtains the off-board air quality along the route in advance according to the navigation route of the vehicle, that is, the off-board air quality information 12 may include various air quality data along the navigation route. The equipment control module can take measures in advance according to various air quality data acquired in advance. For example, when the acquired internet data shows that PM2.5 data of a region to be passed in front exceeds a standard, the device control module 20 may control the window to close and the air cleaning apparatus to open so as to ensure that the air quality in the vehicle is not polluted by the air quality outside the vehicle when passing through the region.

Further, the device control module 20 includes a processing module 21, an air purifying device control module 22, and an air interaction device control module 23, where the processing module 21 analyzes the air quality information 11 in the vehicle and the air quality information 12 outside the vehicle, and determines to adjust the air in the vehicle in a manner of air interaction or purification inside and outside the vehicle, so as to form a trigger message 211.

The air purification apparatus control module 22 selects whether to trigger the corresponding air purification apparatus 200 to operate according to the trigger information 211. The air cleaning device 200 may be communicatively coupled to the air cleaning device control module 22 via bluetooth, wiFi, or the like. That is, the consumer can additionally purchase the air cleaning device 200, and wirelessly connect to the in-vehicle air quality control system of the present invention, without modifying the vehicle itself to load the air cleaning device 200.

The air interaction device control module 23 selects whether to trigger the corresponding air interaction device 100 to operate according to the trigger information 211. The air interaction device 100 may be implemented as a window system and/or an air conditioning system carried by a vehicle itself, and may be connected by a wireless manner such as bluetooth, wiFi, or the like, or by a wired manner, which is not limited by the present invention.

The processing module 21 analyzes the in-vehicle air quality information 11 and the out-vehicle air quality information 12, and determines whether the in-vehicle air quality needs to be adjusted and the adjustment mode to trigger the corresponding air purifying device 200 or the air interaction device 100 to operate.

Specifically, the processing module 21 analyzes whether the air in the vehicle needs to be adjusted according to the air quality information 11 in the vehicle. For example, when the in-vehicle air information 11 shows that the in-vehicle air contains harmful gases such as second-hand smoke, the content of oxygen and carbon dioxide is high, the odor or the PM10 and PM2.5 do not meet one or more conditions of standards, etc., the in-vehicle air is judged to need to be adjusted. When the in-vehicle air information 11 indicates that the in-vehicle air quality is normal, and there are no harmful gases, oxygen and carbon dioxide contents, PM10, PM2.5 are normal, etc., it is determined that the in-vehicle air does not need to be adjusted, the air purifying device 200 or the air interaction device 100 does not need to be triggered to operate, or the current operating state of the air interaction device does not need to be changed.

Further, when the processing module 21 determines that the air in the vehicle needs to be adjusted, the analysis is applicable to the adjustment of the purification or air interaction mode according to whether the air quality of the vehicle exterior reflected by the air quality information 12 is good. For example, according to whether PM2.5 of the air outside the vehicle meets the standard, whether PM10 meets the standard, whether the content of toxic gases such as nitrogen dioxide, sulfur dioxide and the like is within a safe range, whether the wind speed and the humidity are suitable for personnel in the vehicle, and the like, the adjustment mode is analyzed and selected.

When the external air quality information 12 indicates that the external air quality is good, as shown in fig. 2A, the adjustment is preferably performed by using an internal-external air interaction mode, that is, the processing module 21 triggers the operation of the air interaction device control module 22 to further control the operation information of the air interaction device 100, for example, opening a vehicle window, opening a ventilation system of an air conditioner, etc., so as to achieve air quality in the air interaction device, as shown in fig. 2B and fig. 2C.

When the external air quality information 12 indicates that the external air quality is poor, as shown in fig. 1A, the processing module 21 triggers the operation of the air interaction device control module 23 and/or the air purification device control module 23 to stop the operation of the air interaction device 100, and starts the air purification device 200. For example, the air interaction device control module 23 is triggered to control the open window to be closed, and the ventilation system of the air conditioner is stopped, so that the outside air is prevented from polluting the air in the vehicle; air quality in the vehicle is purified and adjusted by an air purifier and other devices, as shown in fig. 1B.

It will be appreciated that, although the air inside the vehicle does not need to be adjusted, and the air outside the vehicle has poor quality, the processing module 21 may still form the trigger information 211, so as to trigger the air interaction device control module 23 to operate, and control the air interaction device 100 to stop operating or to close.

That is, the trigger information 211 formed after the analysis of the processing module 21 may include, but is not limited to, whether to activate or deactivate the ventilation system of the air conditioner, whether to open the window, whether to close the window, whether to activate the air cleaning device 200, and so on. The air cleaning device control module 22 and the air interaction device control module 23 trigger the corresponding air cleaning device 200 and the air interaction device 100 to operate according to the trigger information 211.

At the moment, the air quality control system can actively adjust and optimize the air quality in the vehicle, and the control of a driver is not needed, so that the distraction of the driver in the driving process is avoided, and the driving safety is improved. Moreover, the air quality control system can still double-layer ensure the control and optimization of the air quality in the vehicle through a mode of purification and air interaction.

Further, the air interaction device control module 23 includes a window control module 231 and an air conditioning control module 232. The window control module 231 controls the opening and closing, the opening degree, and the like of the window according to the trigger information 211. The air conditioner control module 232 controls the on-off, the set temperature, the wind speed, etc. of the vehicle-mounted air conditioner according to the trigger information 211.

The processing module 21 forms a selection trigger message 212 according to the in-vehicle air quality message 11 and/or the out-vehicle air quality message 12 to selectively trigger the window control module 231 and/or the air conditioner control module 232 to operate. For example, in the rainy day, in order to avoid rainwater entering the vehicle, the processing module 21 selects the air conditioner control module 232 to operate, exchanges air through the ventilation system of the air conditioner, and prevents rainwater from entering the vehicle, so as to form the selection trigger information 212, as shown in fig. 2B. When the weather is clear, the processing module 21 selects the window control module 231 to operate, and uses natural ventilation of air to exchange air, so as to avoid that the personnel in the vehicle are in the air-conditioning environment for a long time, and form the selection triggering information 212, as shown in fig. 2C.

It will be appreciated by those skilled in the art that the window control module 231 and the air conditioning control module 232 may also be activated simultaneously according to preset conditions, and the present invention is not limited thereto. In addition, the person skilled in the art may preset different conditions by triggering the window control module 231 or the air conditioning control module 232, or both, which are only examples and not limiting.

In one embodiment of the present invention, the device control module 20 further includes a setup module 24. The setting module 24 forms setting information 241 according to the triggering information 211, the in-vehicle air quality information 11, and the out-of-vehicle air quality information 12, for setting the corresponding working parameters of the air interaction device 100 and/or the air purification device 200. The setting information 241 may include, but is not limited to, a purge wind speed and a purge time of the purge device, etc., a switching state of each window, a window opening degree, an air conditioning ventilation speed, an air conditioning set temperature, etc.

According to the trigger information 211, the air cleaning device control module 22 triggers the air cleaning device 200 to start. Correspondingly, the setting module 24 forms setting information 241 such as a purge wind speed, a purge operation time, and the like according to the in-vehicle air quality information 11. The air cleaning device control module 22 sets the operation-like parameters of the air cleaning device 200 according to the setting information 241. For example, if the in-vehicle air quality information 11 indicates that there is a loss of harmful gas such as second hand smoke or oxygen in the vehicle, the setting information 241 may indicate that the purge wind speed is highest, so as to achieve rapid purging.

According to the triggering information 211, the window control module 231 is triggered to work. Correspondingly, the setting module 24 forms setting information 241 such as whether the driving area window is opened, whether the co-driving area window is opened, whether the rear seat area window is opened, whether the opening degree such as full opening or half opening is provided, and the like according to the in-vehicle air quality information 11 and the out-vehicle air quality information 12. The window control module 231 sets the working parameters of the window according to the setting information 241. For example, if the in-vehicle air quality information 11 indicates that there is harmful gas such as second-hand smoke in the vehicle, the setting information 241 may indicate that all windows are fully opened to quickly release the second-hand smoke. Or for example, the outside air quality information 12 indicates that the outside wind speed is high and the temperature is low, and the setting information 241 may indicate that only the rear seat area window is half open.

According to the trigger information 211, the air conditioner control module 232 is triggered to operate. Correspondingly, the setting module 24 forms setting information 241 such as an air conditioning ventilation speed level, dehumidification, temperature, whether a front seat area air conditioning vent is opened, whether a rear seat area air conditioning vent is opened, and the like according to the in-vehicle air quality information 11 and the out-vehicle air quality information 12. The air conditioner control module 232 sets the operation parameters of the air conditioning system according to the setting information 241. For example, the in-vehicle air quality information 11 indicates that the temperature in the vehicle is 6 degrees celsius, the humidity is not suitable, more dust exists or the PM10 value is larger, and the setting information 241 may indicate that the air conditioning temperature is 17 degrees celsius, the dehumidification is performed, and meanwhile, the front seat air conditioning ventilation openings and the rear seat air conditioning ventilation openings are all opened.

It will be appreciated by those skilled in the art that the above is by way of example only and not by way of limitation, and that the setting information 241 of other content may be formed in the same manner. Those skilled in the art may design different conditions as needed to form the corresponding setting information 241, and the present invention is not limited thereto.

In another embodiment of the present invention, the in-vehicle air quality control system further comprises a display module 30, wherein the display module 30 displays the in-vehicle air quality information 11 and the out-of-vehicle air quality information 12 so that the in-vehicle personnel can know the current environmental status, in particular, the in-vehicle air quality. The display module 30 may be implemented as a vehicle-mounted display screen, a mobile phone for a person in the vehicle, a tablet, or other electronic devices, and the present invention is not limited thereto.

Such as whether the current air conditioning mode is interactive or purifying, the operating state and operating parameters of the vehicle window, the operating state and operating parameters of the air conditioner, the operating state and operating parameters of the air purifier, etc.

According to another aspect of the present invention, the present invention further provides a method of controlling air quality in a vehicle. The in-vehicle air quality control method can be applied to the in-vehicle air quality control system, achieves the aims and advantages and solves the problems of the invention.

FIG. 4 is a flow chart of the method for adjusting the air quality in the vehicle according to the present invention.

Step 301: the air quality in the vehicle is detected, and the air quality information 11 in the vehicle is formed.

Because the space inside the vehicle is limited, the amplitude and frequency of the change of the air quality in the vehicle are increased, especially under the condition of more people in the vehicle, taking the bus as an example, most of windows of the bus are closed and cannot be opened at present, and when the bus is fully loaded, the carbon dioxide and dust amount of the air in the vehicle can rise in a short time. Therefore, the air quality in the vehicle is detected in real time to deal with the situation, and the air quality in the vehicle can be ensured to be in a better state.

The detection of the air quality in the vehicle can be performed by one or a combination of a PM10 detector, a PM2.5 detector, a temperature detector, a humidity detector, a wind speed detector, a cigarette detector and the like, and the method of the invention is not limited. Correspondingly, the in-vehicle air quality information 11 may include, but is not limited to, PM2.5, PM10, temperature, humidity, whether there are harmful gases, and so forth.

Step 303: an off-board air quality information 12 is obtained.

The acquiring of the external air quality information 12 can be acquired through an external air quality detecting instrument configured by the vehicle, and can also be acquired from a network in a positioning mode. The vehicle-mounted outside air quality detecting instrument can be one or a combination of more of a PM10 detector, a PM2.5 detector, a temperature detector, a humidity detector, a wind speed detector, a cigarette detector and the like.

Most buses are long-distance buses, routed through different areas, particularly cross-provincial buses, that is, for vehicles, the mass of air outside the vehicle is continuously changing without being used in a stationary room, as shown in fig. 1A and 2A. Real-time detection is required when the outside air quality information 12 is acquired using an outside air quality detection instrument, and timely supply is required. When the outside air quality information 12 is acquired from the network, the route can be navigated, and the data corresponding to the route can be acquired in advance, so that the response can be advanced.

Correspondingly, the off-board air quality information 12 may include, but is not limited to, PM2.5, PM10, temperature, humidity, whether there are harmful gases, and the aforementioned parameters for the different sites, among others.

Step 305: and analyzing whether the air in the vehicle needs to be adjusted according to the air quality information 11 in the vehicle.

The in-vehicle air quality information 11 may reflect whether the passenger is in a good air environment according to the detection results of the respective detectors. For example, when the in-vehicle air quality information 11 reflects one or more of second-hand smoke, too high carbon dioxide content, too high temperature and the like, all the passengers on the surface are in a bad air environment, and the in-vehicle air needs to be adjusted and optimized to ensure the health of the passengers.

It will be appreciated that the order of step 303 is not limited by the numerical sequence number. One skilled in the art may first perform step 303, steps 301 and 305; or step 301 is executed first, and then step 305 and step 303 are executed; or step 301 and step 303 are performed simultaneously.

Step 307: and when the air in the vehicle needs to be adjusted, analyzing whether the air outside the vehicle is good or not according to the air quality information 12 outside the vehicle.

That is, whether or not the air outside the vehicle is good affects the air conditioning system in the vehicle, and thus it is necessary to determine whether or not the air outside the vehicle is good.

The outside air quality information 12 can reflect whether the outside air environment quality is good. For example, when the outside air PM2.5 or PM10 exceeds the standard, it indicates that the outside air is poor. For example, when the outside air contains toxic gas, it indicates that the outside air is poor. At this time, the standard of good air can be preset according to the requirements of the user besides the national standard, but cannot be inconsistent with the national standard so as to avoid being threatened by health.

Step 309: when the air outside the vehicle is good, an air interaction device 100 is triggered to operate.

Because the air outside the vehicle is good, the air exchange circulation inside and outside the vehicle can be realized by opening the vehicle window or the air conditioning ventilation system, thereby adjusting the air quality inside the vehicle. For example, when the inside and outside air is circulated, the carbon dioxide and oxygen ratio in the vehicle is normal, and the dust amount and PM2.5 are reduced.

Step 311: and setting working parameters of the air interaction device 100 according to the air quality information 12 outside the vehicle and the air quality information 11 inside the vehicle.

Corresponding operating parameters of the air interaction device 100 can be set according to different air quality conditions inside and outside the vehicle, so as to provide services for personnel in the vehicle more humanized and in accordance with requirements. For example, the opening size of the window is set according to the wind speed outside the vehicle, whether it is a front window or a rear window. For example, the ventilation speed of the air conditioner is set according to the severity of the air in the vehicle, and if the air in the vehicle contains toxic gas, the highest wind speed is set.

In particular, when the off-board air quality information 12 is acquired through a network, the operation parameters of the air interaction device 100 may be preset.

Step 313: when the air is bad outside the vehicle, i.e. below a preset level, an air purification device 200 is triggered to operate.

Because the air outside the vehicle is bad, if the air inside and outside the vehicle exchanges and circulates, the air inside the vehicle is polluted by the air outside the vehicle, and the adjustment function cannot be achieved. The air conditioning can be achieved by purifying the air in the vehicle by the air purifying device 200.

Step 315: according to the air quality information 11 in the vehicle, the working parameters of the air purifying device 200 are set.

According to the in-vehicle air quality information 11, the in-vehicle air quality condition is reflected, and the working parameters of the air purifying device 200 are set correspondingly. For example, the purge wind level is set according to the severity of the air in the vehicle, and the highest wind speed is set if the air in the vehicle contains toxic gas. The basic purge operation time is set, for example, according to the air condition in the vehicle, so that the effective purge duration is packed.

Further, in order to improve the working efficiency of the air purification apparatus 200 without being disturbed by the air outside the vehicle, the step 313 may be further performed with the step 308: so that the space inside the vehicle is closed. Such as closing an open window, stopping an air conditioning ventilation system, etc.

Step 317: and when the air in the vehicle is good, continuously monitoring the air quality in the vehicle. That is, when the in-vehicle air is good, steps 301 and 303 are performed until the in-vehicle air quality needs to be adjusted to perform the subsequent steps.

Of course, the above step 305 is not an essential step, and steps 307, 308, 309 may be executed after analyzing whether the air outside the vehicle is good or not even if the air inside the vehicle is not required to be adjusted but is in a good state. That is, when the in-vehicle air quality information 11 shows that the in-vehicle air quality is good, in order to avoid contamination by the outside air quality, when the outside air is bad, the in-vehicle space is closed, and the operation of the air cleaning device 200 is triggered.

Fig. 5 is a schematic diagram of an in-vehicle air flow adjustment for an air interaction device 100, such as a vehicle window system and an air conditioning system, in the in-vehicle air quality control method according to the present invention.

Step 402: based on the in-vehicle air quality information 11 and the out-of-vehicle air quality information 12, a selection trigger information 212 is formed.

The selection trigger information 212 includes, but is not limited to, whether to open a window, whether to open an air conditioner, whether to open an air conditioning ventilation system, and the like. Specifically, the formation of the selection trigger information 212 may be formed by analyzing the in-vehicle air quality information 11 and the out-of-vehicle air quality information 12 using the trigger module 21, and the trigger module 21 may be implemented as a central processor, a server, or the like, and the present invention is not limited thereto.

For example, if the amount of rain or wind speed outside the vehicle, which is displayed according to the outside air quality information 12, exceeds a preset value, the selection trigger information 212 displays triggering air conditioning ventilation instead of opening windows for comfort in the vehicle.

Step 403: and judging whether the quality of the air outside the vehicle is good or not according to the quality information 12 of the air outside the vehicle.

Step 404: when the quality of the air outside the vehicle is good, the operation of a window system is triggered according to the selection triggering information 212.

When the selection trigger information 212 indicates that the window is triggered to exchange air between the interior and exterior of the vehicle, the window system is triggered to operate, e.g., the closed window is opened.

Step 406: and setting working parameters of the vehicle window system according to the air quality information 11 in the vehicle and the air quality information 12 outside the vehicle.

For example, working parameters such as whether the driving area window is opened, whether the co-driving area window is opened, whether the rear seat area window is opened, whether the vehicle is fully opened or half opened and the like are set. The difference between the air quality information 11 in the vehicle and the air quality information 12 outside the vehicle also affects the setting of the working parameters, for example, the air quality information 12 outside the vehicle shows that the wind speed outside the vehicle is high, and the temperature is low, and only the vehicle window in the rear seat area is half-opened.

Or step 408: when the quality of the air outside the vehicle is good, an air conditioning system is triggered to work according to the selection triggering information 212.

When the selection trigger information 212 indicates that the air conditioning system is triggered to exchange air between the interior and exterior of the vehicle, the window system is triggered to operate, such as when the ventilation system is started, when the heating or warming system is started, when the dehumidification function is started, etc.

Step 410: and setting working parameters of the air conditioning system according to the air quality information 11 in the vehicle and the air quality information 12 outside the vehicle.

For example, working parameters such as air conditioning ventilation speed, dehumidification, temperature, whether the front seat area air conditioning ventilation opening is opened, whether the rear seat area air conditioning ventilation opening is opened and the like are set. Likewise, the difference between the in-vehicle air quality information 11 and the out-of-vehicle air quality information 12 also affects the setting of the operating parameters. For example, the air quality information 12 indicates that there is second hand smoke in the vehicle, and the front seat area and rear seat area air conditioning vents are all open to quickly exchange air.

Step 412: when the air quality outside the vehicle is poor, the space inside the vehicle is closed.

It will be appreciated that the order of occurrence and numerical order of the steps described above are for illustration only and not limiting, e.g. step 403 may be performed before step 402.

It will be appreciated by persons skilled in the art that the embodiments of the invention described above and shown in the drawings are by way of example only and are not limiting.
