Referring to FIG. 1 , an in-vehicle system 100 configured in an automobile 300 (see FIG. 2 ) is exemplarily shown. The in-vehicle system 100 includes, for example, a trip recording device 2 and an in-vehicle air quality control system 1 according to an embodiment of the present invention. The driving recorder 2 is used to record at least the image information of the external environment viewed from the front of the vehicle. The vehicle interior air quality control system 1 is used to control the air quality in the vehicle 300 , and may include an air curtain 11 , an air quality detection module 12 , an air filter device 13 , and a control unit 14 .

The air curtain 11 is suitable for being installed on the vehicle 300 and generates a Airflow curtain. In this embodiment, the air door curtain 11 can block an interior space 3 of the vehicle 300 into at least a first space 31 and a second space 32 , as shown in FIG. 2 . Specifically, the air door curtain 11 can be composed of, for example, four door curtain parts. When activated, each door curtain part generates a corresponding air curtain, and these air curtains constitute the air curtain, and for example, the corresponding air curtains of the two rear seats can be combined. The first space 31 is blocked from, for example, the second space 32 corresponding to the driver's seat and the passenger's seat. Please note that the first space 31 is often used to place an infant seat.

The air quality detection module 12 is suitable for being disposed in the inner space 3 and is operable to selectively detect the air quality of any one of the inner space 3 , the first space 31 and the second space 32 . More specifically, in this embodiment, the air quality detection module 12 may include at least two detection components (not shown) respectively disposed in the first space 31 and the second space 32 .

The air filtering device 13 is adapted to be installed in the inner space 3 and operate to filter out suspended particles, such as PM2.5, PM10, etc., contained in the inner space 3 , so as to filter the air in the inner space 3 .

The control unit 14 can be implemented by, for example, a computer unit, and is adapted to be electrically connected to the driving recorder 2 to receive the image information from the driving recorder 23 . In addition, the control unit 14 can support a networking function to obtain information from, for example, the driving recorder 2 . The information of an air quality information website, such as the air quality information of the area where the vehicle 300 is located, has image recognition, analysis and processing functions. In this embodiment, the control unit 14 is also connected to the air curtain 11. The air quality detection module 12 and the air filter device 13 are operated to control the operation of the air curtain 11 , the air quality detection module 12 and the air filter device 13 .

Hereinafter, referring to FIG. 1 and FIG. 3 , how the control unit 14 executes a vehicle air quality control program will be described in detail by way of example. The in-vehicle air quality control routine includes, for example, the following steps S31 to S42.

First, in step S31, the control unit 14 collects the image information of the external environment of the car recorded by the driving recorder 2 and the air quality information of the area where the car is located.

Then, in step S32, the control unit 14 utilizes image recognition technology to determine whether the image information does not match a plurality of specific conditions. These specific conditions are related to road conditions, facilities and environment, and specifically, these specific conditions may include, for example, traffic jam conditions, tunnel facility conditions, and smoke and haze conditions. If the determination result is affirmative, that is, if the control unit 14 determines that the external environment of the vehicle 300 is free of traffic jams, tunnel facilities and smoke and haze, the flow will proceed to step S33. On the contrary, if the determination result is negative, that is, if the control unit 14 determines that the external environment of the vehicle 300 has any one of traffic jams, tunnel facilities and smoke and haze, the flow will proceed. Go to step S34. It is worth mentioning that, in other embodiments, the control unit 14 can also be based on a GPS provided by a navigation device (not shown, which can be combined with the driving recorder 2 to form a single navigation driving recorder). speed data to determine whether there is a traffic jam in the external environment, and can compare the The GPS coordinates of 300 and the coordinates of the Point of Interest (POI) corresponding to the tunnel are used to determine whether the car 300 is passing through the tunnel facility (this means that the external environment matches the tunnel facility condition).

In step S33, the control unit 14 determines whether the air quality information meets a predetermined air quality standard (eg, the concentration of PM2.5 is not greater than 15.4 μg/m ³ , the concentration of PM10 is not greater than 54 μg/m ³ , etc.). If the determination result is positive, that is, if the control unit 14 determines that the air quality of the area where the vehicle 300 is located is better than or equivalent to the predetermined air quality standard (ie, the air contains relatively little CO, sulfur In the case of particles, suspended particles (such as PM2.5, PM10, etc.), the process will proceed to step S37. On the contrary, if the determination result is negative, that is, if the control unit 14 determines that the air quality of the area where the vehicle 300 is located is worse than the predetermined air quality standard (that is, the air contains relatively more CO, sulfide, suspended particles, etc.), the flow will proceed to step S34.

In step S34, the control unit 14 activates the air curtain 11 to generate the airflow curtain that blocks the first space 31 and the second space 32 from each other, and makes the air quality detection module 12 detect the interior The air quality of the space 3 is obtained to obtain a detection result corresponding to the inner space 3 . It is worth noting that in this case, since the air curtain 11 is activated, the air pollution from the external environment will be blocked by the air curtain and it is difficult to enter the first space 31 , thereby ensuring the first space 31 The inner air quality is protected from the influence of the outer air pollution.

Next, in step S35, the control unit 14 determines that the internal space corresponds to the Whether the detection result in time 3 meets the predetermined air quality standard. If the determination result is affirmative, step S35 is repeated; otherwise, this situation represents that the air quality in the inner space 3 is relatively bad, and the flow will go to step S36.

In step S36 , the control unit 14 activates the air filtering device 13 to filter the air in the interior space 3 , thereby achieving air purification of the interior space 3 to improve the air quality of the interior space 3 .

On the other hand, in step S37 , the control unit 14 enables the air quality detection module 12 to detect the air quality of the first space 31 to obtain a detection result corresponding to the first space 31 . In this case, since the air door curtain 11 has not been activated, the air mass of the first space 31 is the air mass of the second space 32 and the inner space 3 .

Then, in step S38 immediately after step S37, the control unit 14 determines whether the detection result corresponding to the first space 31 meets the predetermined air quality standard. If the determination result is affirmative, the flow returns to step S32; otherwise (it means that the air quality of the first space 31 is relatively poor), the flow will go to step S39.

In step S39, the control unit 14 activates the air curtain 11 to generate the airflow curtain that blocks the first space 31 and the second space 32 from each other. Then the flow proceeds to step S36 to filter the air in the inner space 3 .

In step S40 after step S36, the control unit 14 enables the air quality detection module 12 to detect the air quality (for example, the concentrations of PM2.5 and PM10, but not limited to this example) of the second space 32 ), and estimate the air quality deterioration rate of the second space 32 accordingly (eg For example, the concentration of PM2.5 and PM10 versus time).

Next, in step S41, the control unit 14 determines whether the air purification rate of the air filter device 13 is greater than the air quality deterioration rate. If the determination result is affirmative, the flow will go to step S42, otherwise, the flow will return to step S40, so as to repeatedly execute steps S40 and S41.

In step S42, the control unit 14 stops the operation of the air curtain 11.

Next, in step S43, the control unit 14 determines whether the air quality of the second space 32 detected by the air quality detection module 12 meets the predetermined air quality standard. If the determination result is affirmative, the process will go to step S44; otherwise, the process will repeatedly execute step S43.

When the control unit 14 determines that the air quality of the second space 32 conforms to the predetermined air quality standard, then, in step S44, the control unit 14 stops the operation of the air cleaning device 13, and then the flow returns to Step S32.

However, in other embodiments, regardless of the air purification performance of the air purifying device 13 and the air quality deterioration degree of the second space 32, the control unit 14 can make the air quality detection after step S36. The measuring module 12 detects the air quality of the second space 32 to obtain an air quality detection result corresponding to the second space 32, and makes the air quality detection result meet the predetermined air quality standard only when it is determined that the air quality detection result complies with the predetermined air quality standard. The air curtain 11 and the air cleaning device 13 stop working.

To sum up, since the control unit 14 is determined by the driving record Set 2 whether the recorded image information conforms to the traffic congestion road conditions, tunnel facility conditions or smoke and haze environment conditions, and determine whether the air quality information in the area where the car 300 is located conforms to the predetermined air quality standard to control the air curtain. Therefore, when the control unit 14 determines that the external environment has relatively high air pollution, since the air door curtain 11 has been activated first, at least the first space 31 can be ensured first (such as infants and young children usually ride The space where the location is located) is blocked from air pollution from the outside, and then the air purifying device 13 is activated when the air quality in the vehicle is lower than the predetermined air quality standard, so as to effectively and immediately maintain the interior space 3 at a relatively high level. good air quality. Therefore, the vehicle interior air quality control system 1 of the present invention can indeed achieve the object of the present invention.

However, the above are only examples of the present invention, and should not limit the scope of implementation of the present invention. Any simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the contents of the patent specification are still included in the scope of the present invention. within the scope of the invention patent.
