In order to solve the technical problem, the invention provides an in-vehicle air quality control method which is used for controlling the air quality in an automobile and is executed by a control unit. The vehicle is provided with an air curtain for generating an air flow curtain for partitioning an interior space of the vehicle into at least a first space and a second space, an air filtering device, and a driving recording device. The method for controlling the quality of air in the vehicle comprises the following steps: (A) Collecting image information of the external environment of the automobile recorded by the driving recording device and air quality information of the area where the automobile is located; (B) Determining whether the image information is not matched with a plurality of specific conditions related to road conditions, facilities and environments by using an image identification technology, and determining whether the air quality information conforms to a preset air quality standard; (C) When it is determined that the image information matches one of the specific conditions or the air quality information does not meet the predetermined air quality standard, activating the air curtain to generate an airflow curtain blocking the first space and the second space from each other, and detecting the air quality of the interior space to obtain a detection result corresponding to the interior space; and (D) activating the air purification device when it is determined that the detection result corresponding to the interior space does not meet the predetermined air quality standard.

Preferably, the method for controlling the quality of air in a vehicle according to the present invention further includes, after the step (D) or the step (F), the steps of: (G) Detecting the air quality of the second space and estimating the air quality degradation rate of the second space according to the air quality; (H) When the air purification rate of the air filtering device is determined to be greater than the air quality degradation rate, stopping the operation of the air door curtain; and (I) stopping the operation of the air filtering device when the air quality of the second space is determined to meet the predetermined air quality standard.
Preferably, in the method for controlling the quality of the air in the vehicle according to the present invention, the specific situations include a vehicle jam situation, a tunnel facility situation, and a smoke haze situation.
In order to solve the technical problem, the invention provides an in-vehicle air quality control system which is used for controlling the air quality in an automobile. The vehicle is provided with a driving recording device. The in-vehicle air quality control system comprises an air door curtain, an air quality detection module, an air filtering device and a control unit. The air door curtain is suitable for being arranged on the automobile and generates an airflow door curtain when being started, and the airflow door curtain can at least block an inner space of the automobile into a first space and a second space. The air quality detection module is suitable for being arranged in the inner space and can be operated to selectively detect the air quality of any one of the inner space, the first space and the second space. The air filtering device is suitable for being arranged in the inner space and is operated to filter the air in the inner space. The control unit is suitable for receiving the image information of the external environment of the automobile recorded by the driving recording device and obtaining the air quality information of the area where the automobile is located, and is operated to control the operation of the air door curtain, the air quality detection module and the air filtering device.
The control unit determines whether the image information is not matched with a plurality of specific conditions related to road conditions, facilities and environments by using an image recognition technology, and determines whether the air quality information meets a predetermined air quality standard.
When the control unit determines that the image information matches one of the specific conditions or the air quality information does not meet the predetermined air quality standard, the control unit activates the air curtain to generate the air curtain blocking the first space and the second space from each other, and enables the air quality detection module to detect the air quality of the internal space to obtain a detection result corresponding to the internal space.
When the control unit determines that the detection result corresponding to the inner space does not meet the predetermined air quality standard, the control unit enables the air filtering device to be started to filter the air in the inner space.
Preferably, in the in-vehicle air quality control system according to the present invention, when the control unit determines that the image information is not matched with the specific situations and determines that the air quality information meets the predetermined air quality standard, the control unit enables the air quality detection module to detect the air quality of the first space to obtain a detection result corresponding to the first space. When the control unit determines that the detection result corresponding to the first space does not meet the predetermined air quality standard, the control unit activates the air curtain to generate the air flow curtain for blocking the first space and the second space from each other, and then activates the air filtering device to filter the air in the inner space.
Preferably, in the in-vehicle air quality control system according to the present invention, after the air filtering device performs the air filtering operation, the control unit causes the air quality detection module to detect the air quality of the second space and accordingly estimate the air quality degradation rate of the second space, when the control unit determines that the air purification rate of the air filtering device is greater than the air quality degradation rate, the control unit stops the operation of the air curtain, and when the control unit determines that the air quality of the second space detected by the air quality detection module meets the predetermined air quality standard, the control unit stops the operation of the air filtering device.
Preferably, in the in-vehicle air quality control system according to the present invention, the specific situations include a vehicle jam situation, a tunnel facility situation, and a smoke haze situation.

[ detailed description ] embodiments
Before the present invention is described in detail, it should be noted that in the following description, similar components are denoted by the same reference numerals.
Referring to fig. 1, an in-vehicle system 100 configured in an automobile 300 (see fig. 2) is schematically illustrated. The vehicle-mounted system 100 includes, for example, a driving recording device 2 and an in-vehicle air quality control system 1 according to an embodiment of the present invention. The drive recording device 2 is used for recording image information of an external environment at least viewed from the front of the vehicle. The in-vehicle air quality control system 1 is used for controlling the air quality in the vehicle 300, and may include an air curtain 11, an air quality detection module 12, an air filtering device 13, and a control unit 14.
The air curtain 11 is adapted to be disposed in the vehicle 300 and to create an air curtain upon startup. In the present embodiment, the 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. In particular, the air curtain 11 can be composed of, for example, four curtain portions, each of which, when activated, generates a corresponding curtain of air flow, which constitutes the air curtain, and which can block the first space 31, corresponding to, for example, two rear seats, from the second space 32, corresponding to, for example, a driver seat and a passenger seat. Note that the first space 31 is often used for placing an infant seat.
The air quality detecting module 12 is adapted to be disposed in the internal space 3 and is operable to selectively detect the air quality of any one of the internal space 3, the first space 31 and the second space 32. More specifically, in the present 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 disposed in the internal space 3 and is operative to filter out suspended particles, such as PM2.5, PM10, etc., contained in the internal space 3 to filter out the air in the internal space 3.
The control unit 14 can be implemented, for example, as a computer unit and is adapted to be electrically connected to the tachograph means 2 for receiving the image information from the tachograph means 23, and in addition, the control unit 14 can support networking functions for obtaining information from, for example, an air quality information website, such as air quality information of the area where the car 300 is located, and has image recognition, analysis and processing functions. In this embodiment, the control unit 14 is further connected to the air curtain 11, the air quality detection module 12 and the air filtering device 13, and is operative to control operations of the air curtain 11, the air quality detection module 12 and the air filtering device 13.
Hereinafter, how the control unit 14 performs an in-vehicle air quality control routine will be described in detail with reference to fig. 1 and 3. The in-vehicle air quality control program 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 vehicle recorded by the driving recording device 2 and the air quality information of the area where the vehicle is located.
Then, in step S32, the control unit 14 determines whether the image information matches any of a plurality of specific situations by using an image recognition technique. The specific situations are related to road conditions, facilities and environments, and specifically, the specific situations can include, for example, a traffic jam situation, a tunnel facility situation and a smoke haze situation. If the determination result is positive, that is, if the control unit 14 determines that the outside environment of the automobile 300 is free from a traffic jam situation, tunnel facilities, and a smoke haze situation, the flow will proceed to step S33. Conversely, if the determination result is negative, that is, if the control unit 14 determines that the environment outside the automobile 300 is one of the jammed condition, the tunnel facility, and the smoke haze condition, the flow proceeds to step S34. It should be noted that, in other embodiments, the control unit 14 can also determine whether the external environment is jammed according to speed data of a GPS provided by a navigation device (not shown, which can be combined with the driving recording device 2 into a single navigation driving recorder), and can determine whether the car 300 is passing through a tunnel facility (which means that the external environment matches the tunnel facility) by comparing GPS coordinates of the car 300 with Point of Interest (POI) coordinates corresponding to the tunnel.
In step S33, the control unit 14 determines whether the air quality information meets a predetermined air quality criterion (e.g., the concentration of PM2.5 is not more than 15.4 μ g/m3, the concentration of PM10 is not more than 54 μ g/m3, etc.). If the determination is positive, that is, if the control unit 14 determines that the air quality of the area in which the automobile 300 is located is better than or equal to the predetermined air quality standard (i.e., the air contains relatively less CO, sulfides, aerosols (e.g., PM2.5, PM 10), etc.), the flow proceeds to step S37. Conversely, if the determination is negative, that is, if the control unit 14 determines that the air quality of the area in which the automobile 300 is located is worse than the predetermined air quality standard (i.e., the air contains relatively more CO, sulfides, aerosols, etc.), the flow proceeds to step S34.
In step S34, the control unit 14 activates the air curtain 11 to generate the air curtain for blocking the first space 31 and the second space 32 from each other, and causes the air quality detection module 12 to detect the air quality of the internal space 3 to obtain a detection result corresponding to the internal space 3. It is noted that in this case, as the air curtain 11 is activated, the air from the outside environment will be blocked by the air curtain and less accessible to the first space 31, thereby ensuring that the air quality in the first space 31 is protected from outside air.
Next, in step S35, the control unit 14 determines whether the detection result corresponding to the inner space 3 meets the predetermined air quality standard. If the determination result is positive, repeating the step S35; otherwise, this situation represents that the air quality in the inner space 3 is relatively bad, the process proceeds to step S36.
In step S36, the control unit 14 activates the air filtering device 13 to filter the air in the internal space 3, thereby achieving air purification of the internal space 3 to improve the air quality of the internal 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 curtain 11 is not yet activated, the air quality of the first space 31 is the air quality 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 positive, the flow returns to step S32; otherwise (this represents that the air quality of the first space 31 is relatively bad), the process proceeds to step S39.
In step S39, the control unit 14 activates the air curtain 11 to generate the air curtain blocking the first space 31 and the second space 32 from each other. The flow then proceeds to step S36 to filter the air in the internal space 3.
In step S40 after step S36, the control unit 14 enables the air quality detection module 12 to detect the air quality (e.g., but not limited to, the concentrations of PM2.5 and PM 10) of the second space 32, and accordingly, estimates the air quality degradation rate (e.g., the change of the concentrations of PM2.5 and PM10 with respect to time) of the second space 32.
Next, in step S41, the control unit 14 determines whether the air cleaning rate of the air filtering device 13 is greater than the air quality deterioration rate. If the determination result is positive, the flow proceeds to step S42, otherwise, the flow returns to step S40 to repeatedly execute step S40 and step 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 flow will proceed to step S44; otherwise, the flow will repeat the execution of step S43.
When the control unit 14 determines that the air quality of the second space 32 meets the predetermined air quality criterion, then, in step S44, the control unit 14 stops the operation of the air filter 13, and then, the flow returns to step S32.
However, in other embodiments, regardless of the air purification performance of the air filtering device 13 and the air quality degradation degree of the second space 32, after step S36, the control unit 14 can enable the air quality detection module 12 to detect the air quality of the second space 32 to obtain an air quality detection result corresponding to the second space 32, and disable the air curtain 11 and the air filtering device 13 when determining that the air quality detection result meets the predetermined air quality standard.
As described above, since the control unit 14 controls the operation of the air curtain 11 according to the determination result of determining whether the image information recorded by the driving recording device 2 corresponds to the traffic jam condition, the tunnel facility condition or the smoke haze environment condition and determining whether the air quality information of the area where the automobile 300 is located corresponds to the predetermined air quality standard, when the control unit 14 determines that the external environment has relatively high air pollution, since the air curtain 11 is already activated, it is at least possible to ensure that the first space 31 (the space where the infant is usually located) is blocked from the external air pollution first, and then activate the air filtering device 13 when the air quality in the automobile is lower than the predetermined air quality standard, so as to effectively and real-timely maintain the internal space 3 at a relatively good air quality condition. Therefore, the in-vehicle air quality control system 1 of the present invention can surely achieve the object of the present invention.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
