[0002] Air purification is an important means to improve air quality, ensure health, and enhance the user experience. Existing technologies generally perform air purification when the air quality inside the vehicle is poor, which is not conducive to the physical health of users. How to prevent users from inhaling poor-quality air inside the vehicle has become an urgent problem to be solved. Summary of the Invention

[0003] In view of this, this application provides an air purification method, system, vehicle, storage medium, and program product, which purify the air before it enters the vehicle cockpit to improve the air quality inside the vehicle.

[0004] In a first aspect, this application provides an air purification method applied to a vehicle. The method includes:

[0005] Using an air purification device disposed at a position associated with the air inlet of the vehicle's air conditioner to perform a purification operation on the air passing through the air inlet of the vehicle's air conditioner, so that the air entering the vehicle cockpit is the purified air obtained through the purification operation. The purification operation includes: electrostatically loading the air passing through the air inlet of the vehicle's air conditioner.

[0006] Beneficial Effects: This application uses an air purification device disposed at a position associated with the air inlet of the vehicle's air conditioner to perform an electrostatic loading purification operation on the air in advance after the air passes through the air inlet of the air conditioner and before it enters the vehicle cockpit, so that the air entering the vehicle cockpit is the purified air obtained through the purification operation. Thus, the users inside the cockpit are completely prevented from coming into contact with poor-quality air, which is beneficial to protecting the physical health of users and improving the user experience.

[0007] In an optional implementation, the method further includes:

[0008] When it is detected that the air conditioner is in the external circulation mode and the quality level of the outdoor air quality is greater than the quality level threshold, comparing the outdoor air quality with the indoor air quality to obtain a first comparison result;

[0009] When the first comparison result indicates that the outdoor air quality is lower than the indoor air quality, switching the air conditioner from the external circulation mode to the internal circulation mode;

[0010] When the first comparison result indicates that the outdoor air quality is not lower than the indoor air quality, determining that the air conditioner continues to be in the external circulation mode.

[0011] Beneficial effects: When it is detected that the air conditioner is in the external circulation mode and the quality grade of the outdoor air quality is greater than the quality grade threshold, if it is further detected that the outdoor air quality is lower than the indoor air quality, it indicates that although the outdoor air quality is in a relatively good state, it is still lower than the indoor air quality. At this time, the air conditioner is switched from the external circulation mode to the internal circulation mode to provide a comfortable breathing environment for the user.

[0012] In an alternative embodiment, the method further includes:

[0013] When it is detected that the air conditioner is in the internal circulation mode and the quality grade of the outdoor air quality is greater than the quality grade threshold, compare the outdoor air quality with the indoor air quality to obtain a second comparison result;

[0014] When the second comparison result indicates that the outdoor air quality is higher than the indoor air quality, switch the air conditioner from the internal circulation mode to the external circulation mode;

[0015] When the second comparison result indicates that the outdoor air quality is not higher than the indoor air quality, determine that the air conditioner continues to be in the internal circulation mode.

[0016] Beneficial effects: When it is detected that the air conditioner is in the internal circulation mode and the quality grade of the outdoor air quality is greater than the quality grade threshold, if it is further detected that the outdoor air quality is higher than the indoor air quality, it indicates that the outdoor air quality is relatively good and the outdoor air quality is in a relatively good state compared to the indoor air quality. At this time, the air conditioner is switched from the internal circulation mode to the external circulation mode, and fresh air with good quality is introduced from the outside, thereby improving the air quality in the cockpit.

[0017] In an alternative embodiment, the method further includes:

[0018] When it is detected that the quality grade of the outdoor air quality is not greater than the quality grade threshold, control the air conditioner to be in the internal circulation mode.

[0019] Beneficial effects: When it is detected that the air conditioner is in the internal circulation mode and the quality grade of the outdoor air quality is not greater than the quality grade threshold, it indicates that the outdoor air quality is not sufficient to significantly improve the indoor air quality. At this time, regardless of whether the indoor air quality is better than the outdoor air quality, the air conditioner mode remains in the internal circulation state, avoiding introducing poor-quality air from the outside and keeping the indoor air quality in a relatively good state.

[0020] When it is detected that the air conditioner is in the external circulation mode and the quality grade of the outdoor air quality is not greater than the quality grade threshold, in order to prevent polluted air from the outside from entering the cockpit, the air conditioner is switched from the external circulation mode to the internal circulation mode, and the indoor air is filtered through the purification operation of the air purification device to maintain the good state of the indoor air quality, thereby improving the user experience.

[0028] Beneficial effects: In this application, a high-voltage direct current output by the air purification device is used to form a corona electrode, and an electrostatic field is formed between the corona electrode and the dust collecting electrode formed by the vehicle's power supply. Thus, before the air enters the air inlet of the air conditioner and before entering the vehicle cockpit, electrostatic loading is performed on the air, making it easier for air pollutants with static electricity to be filtered by the air conditioner, improving the filtering effect. In this way, the air entering the vehicle cockpit is purified air, preventing the user from inhaling air with poor air quality, which not only protects the user's physical health but also improves the user's experience of using the product.

[0063] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0064] According to an embodiment of the present application, an embodiment of an air purification method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.

[0065] In this embodiment, an air purification method is provided, which can be used for a vehicle. Figure 1 It is a flowchart of the air purification method according to an embodiment of the present application, as Figure 1 shown. The process includes the following steps:

[0066] Step S101: Use an air purification device arranged at a position associated with the air inlet of the vehicle's air conditioner to purify the air passing through the air inlet of the vehicle's air conditioner, so that the air entering the vehicle's cockpit is the purified air obtained through the purification operation. The purification operation includes: electrostatically loading the air passing through the air inlet of the vehicle's air conditioner.

[0067] It should be understood that the vehicle's cockpit is an environment with a small internal space and strong airtightness. Passengers in the cockpit will consume oxygen and increase the carbon dioxide concentration, and the switching between the internal and external circulation of the air conditioner can adjust the air freshness and temperature in the cockpit, thereby improving the comfort of the cockpit. Among them, the air inlet of the air conditioner includes an internal circulation air inlet and an external circulation air inlet. When the air conditioner is in the internal circulation mode, the air conditioner mainly intakes air from inside the vehicle through the internal circulation air inlet to isolate pollutants outside the vehicle; when the air conditioner is in the external circulation mode, the air conditioner mainly intakes air from outside the vehicle through the external circulation air inlet to avoid turbid air inside the vehicle.

[0068] In some alternative embodiments, the internal circulation air inlet of the air conditioner is located inside the vehicle, and the external circulation air inlet of the air conditioner is located outside the vehicle. The internal circulation air inlet is connected to the internal circulation air intake pipe, and the external circulation air inlet is connected to the external circulation air intake pipe. The internal circulation air intake pipe and the external circulation air intake pipe are respectively connected to the air filter of the air conditioner via the main pipe. The position associated with the air inlet of the vehicle's air conditioner can be at the main pipe, that is, the air purification device can be arranged at the main pipe. In this way, regardless of whether the air conditioner is in the internal circulation or the external circulation, the air can be purified after passing through the air inlet, and the air entering the vehicle's cockpit will be purified air.

[0069] In some alternative embodiments, the number of air purification devices can also be multiple. The positions associated with the air inlet of the vehicle's air conditioner can be the internal circulation air intake pipe and the external circulation air intake pipe. That is, multiple air purification devices can be respectively arranged in the internal circulation air intake pipe of the air conditioner and the external circulation air intake pipe of the air conditioner, so as to filter the air in advance by using the air purification devices before the air enters the vehicle's cockpit.

[0070] Specifically, the purification operation can be to apply electrostatic loading to the air, and perform pre-treatment on the air before it enters the vehicle's cockpit, so that the particles with static electricity in the air are more easily captured by the air filter of the air conditioner, with high filtration efficiency and effectively preventing pollutants in the air from entering the vehicle's cockpit.

[0071] The related art adopts an air negative ion system, in which oxygen molecules are ionized in a gas discharge tube to form electrons and positive ions. The electrons will be captured by oxygen molecules in the air, thus generating air negative ions. The negative ions are released into the air inside the vehicle. The negative ions have a negative charge and can combine with positively charged particles such as particulate matter, bacteria, and viruses in the air, making these positively charged particles lose their activity, playing a role in purifying the air and removing odors. However, the negative ion generator is generally arranged at the position of the air conditioner outlet, and it will only work when the air quality inside the vehicle is poor or only when pollutants enter the vehicle.

[0072] Compared with the air negative ion system in the related art, the air purification device in the present application is arranged at a position associated with the air inlet of the vehicle's air conditioner. Before the air passes through the air inlet of the air conditioner and enters the vehicle's cockpit, the air will be purified in advance, so that the air entering the vehicle's cockpit is purified air, avoiding users from inhaling air with poor quality and improving the user experience. Moreover, the present application has a higher purification efficiency for pollutants such as dust and bacteria.

[0073] The air purification method provided in this embodiment utilizes an air purification device disposed at a position associated with the air inlet of the vehicle's air conditioner to perform a purification operation of electrostatic loading on the air in advance after the air passes through the air inlet of the air conditioner and before entering the vehicle's cockpit, so that the air entering the vehicle's cockpit is purified air obtained through the purification operation, thereby avoiding the users in the cockpit from contacting the air with poor quality throughout the process, which is beneficial to protecting the users' physical health and improving the users' experience.

[0074] In this embodiment, an air purification method is provided, which can be used for vehicles. Figure 2 It is a flowchart of the air purification method according to an embodiment of the present application, as Figure 2 shown, and this process includes the following steps:

[0075] Step S201: Utilize an air purification device disposed at a position associated with the air inlet of the vehicle's air conditioner to perform a purification operation on the air passing through the air inlet of the vehicle's air conditioner, so that the air entering the vehicle's cockpit is purified air obtained through the purification operation. The purification operation includes: performing electrostatic loading on the air passing through the air inlet of the vehicle's air conditioner.

[0076] Specifically, the above step S201 includes:

[0077] Step S2011: Before the air passing through the air inlet of the vehicle's air conditioner enters the vehicle's cockpit, use the air purification device to form a corona electrode, and use the vehicle's power supply to form a dust collecting electrode, and an electrostatic field is formed between the corona electrode and the dust collecting electrode.

[0078] Specifically, as Figure 3 shown, the air purification device outputs high-voltage direct current, and the output high-voltage direct current serves as the corona electrode 301 of the air purification device. The first power supply of the vehicle is grounded to form a dust collecting electrode 302. An electrostatic field is formed between the corona electrode 301 and the dust collecting electrode 302. It should be noted that the operation of the air purification device to form a corona electrode can be any existing method of the air purification device outputting high-voltage direct current.

[0079] In some alternative embodiments, refer to again Figure 3, the air purification device includes a DC / AC circuit 303, a boost circuit 304, and a rectification circuit 305. Among them, the DC / AC circuit 303 is used to convert the second power supply provided by the vehicle to the air purification device from direct current to alternating current; the boost circuit 304 is used to boost the alternating current converted by the DC / AC circuit 303 to the voltage required by the air purification device, and then convert the alternating current output by the DC / AC circuit 303 into high-voltage alternating current; the rectification circuit 305 is used to convert the high-voltage alternating current output by the boost circuit 304 into high-voltage direct current. It should be noted that the voltage required by the air purification device can be about 6V, and can be specifically set according to the actual scenario.

[0080] In the embodiment of the present application, the DC / AC circuit 303, the boost circuit 304, and the rectification circuit 305 are used to perform DC / AC conversion, boosting, and rectification on the second power supply provided by the vehicle to the air purification device in sequence, so that the high-voltage direct current output by the rectification circuit 305 serves as the corona electrode 301 of the air purification device. Moreover, the first power supply of the vehicle is grounded to form a dust collecting electrode 302, and an electrostatic field is formed by the corona electrode 301 and the dust collecting electrode 302, and then the air passing through the air inlet of the vehicle's air conditioner is electrostatically loaded to improve the filtering efficiency of the air conditioner.

[0081] Refer to again Figure 3 , the DC / AC circuit 303 includes a full-bridge inverter circuit composed of four switching tubes. When the first group of switching tubes (the first transistor on the upper bridge arm and the corresponding fourth transistor on the lower bridge arm) is closed, the direct current of the second power supply starts from the positive pole, passes through the first transistor on the upper bridge arm, the primary coil of the boost circuit 304, and the corresponding fourth transistor on the lower bridge arm, and finally returns to the negative pole of the second power supply. At this time, a current in one direction is formed on the primary coil of the boost circuit 304, which is equivalent to the positive half cycle of the alternating current.

[0082] Then, when the first group of switching tubes is disconnected and the second group of switching tubes (the second transistor on the lower bridge arm and the corresponding third transistor on the upper bridge arm) is closed, the direct current of the second power supply starts from the positive pole, passes through the second transistor on the lower bridge arm, the primary coil of the boost circuit 304, and the corresponding third transistor on the upper bridge arm, and finally returns to the negative pole of the second power supply. At this time, the current direction of the primary coil of the boost circuit 304 is reversed, which is equivalent to the negative half cycle of the alternating current. By continuously repeating the above process, the four switching tubes are alternately turned on or off in pairs. By controlling the time and sequence of the switching tubes being turned on or off, an electric current with an alternating direction continuously appears on the primary coil of the boost circuit 304, realizing the inversion of the direct current provided by the second power supply into alternating current. Among them, the switching tube can be a MOS tube, and the present application is not limited thereto.

[0083] Specifically, refer to again Figure 3, the direct current provided by the second power supply is sequentially connected to the first end of the second inverter chip IC2 after passing through the first triode K1 and the first inverter chip IC1. The first end of the second inverter chip IC2 is respectively connected to the control end of the full-bridge inverter circuit and the second power supply after passing through the second triode K2. Moreover, the second end of the second inverter chip IC2 is connected to the voltage regulator D, and the third end of the second inverter chip IC2 is respectively connected to the first end of the third inverter chip IC3 and the first end of the fourth capacitor C4. The second end of the third inverter chip IC3 is respectively connected to the first end of the fourth inverter chip IC4 and the first end of the fourth resistor R4. The second end of the fourth inverter chip IC4 is respectively connected to the second end of the fourth resistor R4 and the second end of the fourth capacitor C4 after passing through the third resistor R3. Among them, the voltage regulator D is used to stabilize the voltage at the second inverter chip IC2 at a fixed value, and this fixed value can be 5V, which can be specifically set according to the actual scenario.

[0084] In the above embodiment, the first inverter chip IC1, the second inverter chip IC2, the third inverter chip IC3, and the fourth inverter chip IC4 are used to implement the inverting amplification function of the signal.

[0085] In some embodiments, referring again to Figure 3 , the DC / AC circuit further includes a fifth resistor R5, where the fifth resistor R5 is connected between the first triode K1 and the first inverter chip IC1.

[0086] In some embodiments, referring again to Figure 3 , the DC / AC circuit further includes a sixth resistor R6, where the sixth resistor R6 is connected between the first end of the second inverter chip IC2 and the second triode K2.

[0087] It should be noted that the fifth resistor R5 and the sixth resistor R6 have a biasing effect and can be used to set the base bias voltage of the first triode K1 and the second triode K2, determine the operating point of the triode, make the triode work in a suitable region, and ensure the stability and linearity of the circuit. In this embodiment, the fifth resistor R5 and the sixth resistor R6 can be 10KΩ, which can be specifically set according to the actual application scenario.

[0088] In this embodiment, the fourth capacitor C4 can couple the AC signal formed by the full-bridge inverter circuit of the previous stage to the subsequent stage circuit (the RC charging and discharging circuit composed of the fourth capacitor C4, the third resistor R3, and the fourth resistor R4), and the DC bias of the previous stage circuit will not affect the subsequent stage circuit, ensuring the independence and stability of the operating points of each stage circuit. Moreover, in the RC charging and discharging circuit, the third resistor R3 and the fourth resistor R4 can affect the charging and discharging speed of the fourth capacitor C4, thereby affecting the response time of the circuit and the waveform characteristics of the circuit output waveform. The circuit output waveform controls the conduction or cutoff time and sequence of the switching tubes in the full-bridge inverter circuit through the control terminal of the full-bridge inverter circuit. Among them, the fourth capacitor C4 can be 2.2 μF, and the third resistor R3 and the fourth resistor R4 can be 100 KΩ. Specifically, it can be set according to the actual application scenario, and this application is not limited thereto.

[0089] In the embodiment of the present application, the fourth capacitor C4, the third resistor R3, and the fourth resistor R4 form an RC charging and discharging circuit. The RC charging and discharging circuit is connected to the second triode K2 through the second inverter chip IC2, and the second triode K2 is connected to the control terminal of the full-bridge inverter circuit. The third resistor R3 and the fourth resistor R4 affect the charging and discharging speed of the fourth capacitor C4, thereby affecting the circuit output waveform, and further controlling the conduction and cutoff of the switching tubes in the full-bridge inverter circuit to achieve the effect of converting DC power into AC power.

[0090] In some alternative embodiments, referring again to Figure 3 , the DC / AC circuit 303 further includes a first resistor R1, and the first resistor R1 is connected between the second power supply and the first triode K1. Among them, the first resistor R1 can be 1 KΩ, which is used to limit the current passing through the circuit, prevent the current from being too large to damage components, limit the base current, and protect the triode.

[0091] In some alternative embodiments, referring again to Figure 3 , the DC / AC circuit 303 further includes a second resistor R2, and the second resistor R2 is connected between the second power supply and the second triode K2. Among them, the second resistor R2 can be 1 KΩ, which is used to limit the current passing through the circuit, prevent the current from being too large to damage components, limit the base current, and protect the triode.

[0092] In some embodiments, referring again to Figure 3, the DC / AC circuit 303 further includes a first capacitor C0. One end of the first capacitor C0 is connected to the second power supply, and the other end is grounded. In the power supply circuit, the first capacitor C0 is used to filter out the low-frequency ripples in the direct current output by the second power supply, making the output direct current voltage more stable and having stronger stability. In this embodiment, the first capacitor C0 is about 100 μF, the second power supply is 12V, and the connection of the first capacitor C0 to the 12V power supply helps to stabilize the voltage input to the subsequent circuit and reduce the impact of voltage fluctuations on the circuit performance. It should be noted that the specific specifications of the first capacitor C0 and the second power supply can be adjusted according to the actual application scenario.

[0093] In some embodiments, referring again to Figure 3 , the DC / AC circuit 303 further includes a second capacitor C2. One end of the second capacitor C2 is connected to the second power supply, and the other end of the second capacitor C2 is grounded. The second capacitor C2 is used to bypass high-frequency signals to the ground, filter out the high-frequency noise on the power line, and prevent these high-frequency noises from interfering with the normal operation of other components in the circuit. In this embodiment, the second capacitor C2 is about 0.1 μF, but the specific specifications can be adjusted according to the actual application scenario, and this application is not limited thereto.

[0094] In some embodiments, referring again to Figure 3 , the DC / AC circuit 303 further includes a third capacitor C3. One end of the third capacitor C3 is connected to the second power supply through a voltage regulator D, and the other end of the third capacitor C3 is grounded. The third capacitor C3 is used to bypass high-frequency signals to the ground, filter out the high-frequency noise on the power line, and prevent these high-frequency noises from interfering with the normal operation of other components in the circuit. In this embodiment, the third capacitor C3 is about 0.1 μF, but the specific specifications can be adjusted according to the actual application scenario, and this application is not limited thereto.

[0095] In some alternative embodiments, referring again to Figure 3 , the first output terminal of the boost circuit 304 is connected to the first input terminal of the rectifier circuit 305, the second output terminal of the boost circuit 304 is connected to the second input terminal of the rectifier circuit 305, the first output terminal of the rectifier circuit 305 is grounded, and the second output terminal of the rectifier circuit 305 outputs high-voltage direct current.

[0096] Exemplarily, the boost circuit 304 includes a transformer, which converts the alternating current output by the DC / AC circuit 303 into high-voltage alternating current, so as to provide the voltage for forming the corona electrode 301. It should be noted that the first output terminal of the boost circuit 304 and the second output terminal of the boost circuit 304 are the ports for outputting high-voltage alternating current of the secondary coil of the transformer.

[0097] In this application, the first input terminal and the second input terminal of the rectifier circuit 305 are respectively connected to the first output terminal and the second output terminal of the boost circuit 304, and then the high-voltage alternating current of the boost circuit 304 is converted into high-voltage direct current and output through the second output terminal of the rectifier circuit 305, thereby forming the corona electrode 301.

[0098] In some alternative embodiments, the rectifier circuit 305 includes a first rectifier diode D1, a second rectifier diode D2, a third rectifier diode D3, and a fourth rectifier diode D4. Among them, the first input terminal of the rectifier circuit 305 is respectively connected to the input terminal of the first rectifier diode D1 and the output terminal of the second rectifier diode D2, and the output terminals of the first rectifier diode D1 and the third rectifier diode D3 are respectively connected to the first output terminal of the rectifier circuit 305.

[0099] Moreover, the second input terminal of the rectifier circuit 305 is respectively connected to the input terminal of the third rectifier diode D3 and the output terminal of the fourth rectifier diode D4, and the input terminal of the fourth rectifier diode D4 and the input terminal of the second rectifier diode D2 are respectively connected to the second output terminal of the rectifier circuit 305.

[0100] The rectifier circuit 305 of this application can conduct in both the positive half cycle and the negative half cycle of the high-voltage alternating current output by the boost circuit 304, realizing full-wave rectification, thereby converting the high-voltage alternating current into high-voltage direct current.

[0101] In some alternative embodiments, referring again to Figure 3 , the rectifier circuit 305 further includes a seventh resistor R7, and the second output terminal of the rectifier circuit 305 outputs high-voltage direct current after passing through the seventh resistor R7, thereby protecting the circuit.

[0102] In the above embodiment, the first power supply and the second power supply of the vehicle can both be 12V, and can be specifically adjusted according to the actual application scenario, and this application is not limited thereto.

[0103] Step S2012: Use an electrostatic field to electrostatically load the air passing through the air inlet of the vehicle's air conditioner, so that the air conditioner filters the air with static electricity.

[0104] Specifically, electrostatic loading is performed on the air between the corona electrode 301 and the dust collecting electrode 302, so that the pollutants in the passing air are charged with static electricity and are more easily captured and filtered by the air conditioner filter element, so that the air entering the vehicle's cockpit is the purified air obtained through purification operations. Among them, the pollutants can be particles such as pollen, dust, PM2.5, and microorganisms such as bacteria and viruses, and this application is not limited thereto.

[0105] This application utilizes the high-voltage direct current output by the air purification device to form a corona electrode. An electrostatic field is formed between the corona electrode and the dust collecting electrode formed by the vehicle power supply. Thus, after the air enters the air inlet of the air conditioner and before entering the vehicle cockpit, electrostatic loading is applied to the air, making it easier for air pollutants with static electricity to be filtered by the air conditioner, improving the filtering effect. In this way, the air entering the vehicle cockpit is purified air, avoiding the inhalation of poor-quality air by the user, not only ensuring the user's physical health but also enhancing the user's experience of using the product.

[0106] Step S202: When it is detected that the air conditioner is in the external circulation mode and the quality level of the outdoor air quality is greater than the quality level threshold, compare the outdoor air quality with the indoor air quality to obtain a first comparison result; when the first comparison result indicates that the outdoor air quality is lower than the indoor air quality, switch the air conditioner from the external circulation mode to the internal circulation mode; when the first comparison result indicates that the outdoor air quality is not lower than the indoor air quality, determine that the air conditioner continues to be in the external circulation mode.

[0107] In some alternative embodiments, the outdoor air quality and the indoor air quality are respectively related to the pollutant concentrations in the outdoor air and the indoor air. Therefore, the quality levels of the outdoor air quality and the indoor air quality can be determined by monitoring the pollutant concentrations in the outdoor air and the indoor air. Among them, an outdoor air quality sensor can be set outside the vehicle to monitor the pollutant concentration in the outdoor air; an indoor air quality sensor can be set inside the cockpit to monitor the pollutant concentration in the indoor air.

[0108] In some alternative embodiments, the pollution index can be determined based on the classification strategy of pollutant concentrations, and then the quality levels of the outdoor air quality and the indoor air quality can be obtained according to the pollution index. Among them, the classification strategy of pollutant concentrations is used to indicate the pollution index corresponding to any pollutant concentration, and this classification strategy can be set according to test data. It should be noted that different target pollutants may have different corresponding classification strategies.

[0109] Exemplarily, the concentration value of the target pollutant in the outdoor air can be obtained to get the first pollution index C1 of the target pollutant in the outdoor air. Compare the first pollution index C1 with the air pollution index (C2, C3, C4, C5). If C1 < C2, the quality level of the outdoor air quality is excellent; if C2 ≤ C1 < C3, the quality level of the outdoor air quality is good; if C3 ≤ C1 < C4, the quality level of the outdoor air quality is medium; if C4 ≤ C1 < C5, the quality level of the outdoor air quality is poor; if C5 ≤ C1, the quality level of the outdoor air quality is severely polluted.

[0110] Moreover, the concentration value of the target pollutant in the vehicle interior air can be obtained, and the second pollution index C6 of the target pollutant in the vehicle interior air is obtained. The second pollution index C6 is compared with the air pollution indexes (C2, C3, C4, C5). If C6 < C2, the quality grade of the vehicle interior air quality is excellent; if C2 ≤ C6 < C3, the quality grade of the vehicle interior air quality is good; if C3 ≤ C6 < C4, the quality grade of the vehicle interior air quality is medium; if C4 ≤ C6 < C5, the quality grade of the vehicle interior air quality is poor; if C5 ≤ C6, the quality grade of the vehicle interior air quality is severely polluted.

[0111] It should be noted that, in the above embodiments, the description is made by taking the concentration of a single target pollutant as an example. The target pollutant can be a pollutant that is toxic or harmful to the human body, such as formaldehyde, nitrogen dioxide, carbon monoxide, PM2.5, dust, etc. The present application is not limited thereto.

[0112] In some embodiments, taking the vehicle exterior air quality as an example for description, the concentration values of multiple target pollutants in the vehicle exterior air can be obtained, and based on the corresponding grading strategy, the pollution index corresponding to each target pollutant is determined. The pollution indexes of multiple target pollutants are comprehensively analyzed, and corresponding weights are assigned to each target pollutant according to the degree of harm to the human body and the concentration of the target pollutant. The greater the degree of harm and the higher the concentration, the higher the weight. The pollution indexes of multiple target pollutants are weighted and calculated to obtain the total pollution index C7. The total pollution index C7 is compared with the air pollution indexes (C2, C3, C4, C5), so as to determine the quality grade of the vehicle exterior air quality. The quality grade of the vehicle interior air quality is the same by analogy and will not be elaborated here.

[0113] Specifically, when the user does not turn on the air conditioner, if the quality grade of the vehicle exterior air quality is greater than the quality grade threshold (for example, the quality grade of the vehicle exterior air quality is excellent or good), the quality grade of the vehicle interior air quality and the quality grade of the vehicle exterior air quality are compared. If the vehicle exterior air quality is better than the vehicle interior air quality (C1 < C6), the air conditioner circulation mode is switched to the external circulation mode to increase the air circulation in the vehicle interior, reduce the concentration of pollutants in the vehicle interior and improve the vehicle interior air quality at the same time; if the vehicle interior air quality is better than the vehicle exterior air quality (C1 ≥ C6), the air conditioner circulation mode is switched to the internal circulation mode.

[0114] Specifically, when the user turns on the air conditioner and the air conditioner is in the external circulation mode, if the quality level of the outdoor air quality is greater than the quality level threshold (for example, the quality level of the outdoor air quality is excellent or good), compare the quality level of the indoor air quality with the quality level of the outdoor air quality. If the indoor air quality is better than the outdoor air quality (C1≥C6), then switch the air conditioner to the internal circulation state and at the same time prompt the user that "the air conditioner has been switched to the internal circulation due to poor outdoor air quality"; if the outdoor air quality is better than the indoor air quality (C1<C6), then the air conditioner remains in the external circulation state.

[0115] In the embodiment of the present application, when it is detected that the air conditioner is in the external circulation mode and the quality level of the outdoor air quality is greater than the quality level threshold, if it is further detected that the outdoor air quality is lower than the indoor air quality, it indicates that although the outdoor air quality is already in a relatively good state, it is still lower than the indoor air quality. At this time, the air conditioner is switched from the external circulation mode to the internal circulation mode to provide a comfortable breathing environment for the user.

[0116] Step S203, when it is detected that the air conditioner is in the internal circulation mode and the quality level of the outdoor air quality is greater than the quality level threshold, compare the outdoor air quality with the indoor air quality to obtain a second comparison result; when the second comparison result indicates that the outdoor air quality is higher than the indoor air quality, switch the air conditioner from the internal circulation mode to the external circulation mode; when the second comparison result indicates that the outdoor air quality is not higher than the indoor air quality, determine that the air conditioner continues to be in the internal circulation mode.

[0117] Specifically, if it is detected that the air conditioner is in the internal circulation mode and the quality level of the outdoor air quality is greater than the quality level threshold (for example, the quality level of the outdoor air quality is excellent or good), compare the quality level of the indoor air quality with the quality level of the outdoor air quality. If the outdoor air quality is better than the indoor air quality, switch the air conditioner circulation mode to the external circulation mode to improve the indoor air quality, and at the same time prompt the user that "the air conditioner has been switched to the external circulation due to poor indoor air quality"; if the indoor air quality is better than the outdoor air quality, then the air conditioner circulation mode remains in the internal circulation mode.

[0118] In the embodiment of the present application, when it is detected that the air conditioner is in the internal circulation mode and the quality level of the outdoor air quality is greater than the quality level threshold, if it is further detected that the outdoor air quality is higher than the indoor air quality, it indicates that the outdoor air quality is relatively good and the outdoor air quality is in a relatively good state compared to the indoor air quality. At this time, the air conditioner is switched from the internal circulation mode to the external circulation mode to introduce air with good quality from the outside, thereby improving the air quality in the cockpit.

[0119] Step S204, when it is detected that the quality level of the outdoor air quality is not greater than the quality level threshold, control the air conditioner to be in the internal circulation mode.

[0120] Specifically, when the user turns on the air conditioner and the air conditioner is in the internal circulation mode, if the quality level of the outdoor air quality is not greater than the quality level threshold (for example, the quality level of the outdoor air quality is not excellent or good), it indicates that the outdoor air quality is not sufficient to significantly improve the indoor air quality. At this time, regardless of whether the indoor air quality is better than the outdoor air quality, the air conditioner mode remains in the internal circulation state to prevent the introduction of poor-quality air from outside the vehicle and keep the indoor air quality in a relatively good state.

[0121] Moreover, when the air conditioner is in the external circulation mode and the quality level of the outdoor air quality is not greater than the quality level threshold, in order to prevent polluted air from the outside from entering the cockpit, the air conditioner is switched from the external circulation mode to the internal circulation mode, and the indoor air is filtered through the purification operation of the air purification device to maintain the good state of the indoor air quality, thereby improving the user experience.

[0122] Step S205: Upload the quality level of the outdoor air quality and the quality level of the indoor air quality to the server, so that the server can send the quality level of the outdoor air quality and the quality level of the indoor air quality to the user terminal.

[0123] Specifically, a communication connection is established between the vehicle and the server, enabling the vehicle to upload the quality level of the outdoor air quality and the quality level of the indoor air quality to the server, and the server can communicate with the user terminal to push the quality level of the outdoor air quality and the quality level of the indoor air quality to the user, facilitating the user to understand the air quality inside and outside the vehicle and meeting the user's need to view air quality information.

[0124] In some alternative embodiments, regardless of whether the outdoor air quality is better than the indoor air quality, the air quality inside and outside the vehicle should not differ too much. If it is detected that the quality level gap between the quality level of the outdoor air quality and the quality level of the indoor air quality exceeds the gap threshold, it indicates that one or more of the air conditioner, the air purification device, and the air quality sensor have failed, and a fault prompt is issued to remind the user to perform maintenance in a timely manner.

[0125] The air purification method provided in this embodiment utilizes an air purification device to electrostatically load the air in advance before the air enters the vehicle's cockpit, so that the air entering the vehicle's cockpit is purified air, avoiding the users in the cockpit from coming into contact with air of poor quality. Moreover, the air quality outside the vehicle and inside the vehicle is monitored in real time. Combining the relationship between the air quality outside the vehicle and the quality level threshold, as well as the relationship between the air quality inside the vehicle and the air quality outside the vehicle, the circulation mode of the air conditioner is switched, enabling the users in the cockpit to inhale air of better quality, ensuring the health of the users, and improving the user experience. In addition, the quality level of the air quality inside the vehicle and the quality level of the air quality outside the vehicle are sent to the user terminal through the server for the user to view.

[0126] The air purification solution of the present application will be described in detail below in conjunction with a specific application example.

[0127] This application example provides an air purification system, as Figure 4 shown. The air purification system includes an in-vehicle air purifier, an in-vehicle host, an in-vehicle air quality sensor (outside), an in-vehicle air quality sensor (inside), a body controller, and an in-vehicle telematics processor (Telematics BOX, T-BOX). Among them, a communication connection is established between the T-BOX and the telematics service (Telematics Service Provider, TSP), and the TSP can communicate with the user mobile phone APP.

[0128] It should be noted that the in-vehicle air quality sensor (outside) refers to the air quality sensor outside the vehicle arranged outside the vehicle, and the in-vehicle air quality sensor (inside) refers to the air quality sensor inside the cockpit arranged inside the vehicle. The air purification system may also include other vehicle systems such as the power system and the communication system.

[0129] The working principle of the above air purification system is as Figure 5 shown.

[0130] As Figure 5 shown, the in-vehicle air quality sensor (outside) is used to monitor the air quality outside the vehicle and transmit the air quality outside the vehicle to the body controller; the in-vehicle air quality sensor (inside) is used to monitor the air quality inside the vehicle and transmit the air quality inside the vehicle to the body controller.

[0131] After the vehicle is powered on, the in-vehicle air purifier starts to work and electrostatically loads the air, making the particulate matter, bacteria, and viruses in the air carry static electricity. The in-vehicle air purifier electrostatically loads the air entering the air conditioner intake, loading charges on the particulate matter, bacteria, and viruses in the air after they enter the intake, making them "stickier" and easier to be captured by the air conditioner filter.

[0132] The body controller is used to receive the working status signal of the in-vehicle air purifier, feedback the working status signal of the in-vehicle air purifier to the in-vehicle host (such as normal, abnormal, etc.), and receive the outdoor air quality and the indoor air quality.

[0133] The in-vehicle host is used to display the working status of the in-vehicle air purifier on the host, display the outdoor air quality and the indoor air quality on the host, and upload the outdoor air quality and the indoor air quality to the T-BOX.

[0134] The in-vehicle host compares the outdoor and indoor air quality. If the outdoor air quality is better than the indoor air quality, the in-vehicle host sends an instruction to the body controller to switch the air conditioner to the external circulation mode. The body controller receives the air conditioner circulation mode switching instruction, switches the air conditioner circulation mode, and after the air conditioner circulation mode switching is successful, feeds back the relevant signal to the in-vehicle host. The in-vehicle host receives the air conditioner circulation mode feedback signal, and the host pops up a window to prompt the user that the air conditioner circulation mode has been switched.

[0135] The BOX is used to receive the outdoor air quality and the indoor air quality, and upload the outdoor air quality and the indoor air quality to the TSP. The TSP is used to upload the outdoor air quality and the indoor air quality to the cloud server through the TSP. The server is used to receive the outdoor air quality and the indoor air quality, and push the outdoor air quality and the indoor air quality to the mobile APP.

[0136] In some alternative embodiments, the outdoor air quality sensor transmits the first pollution index C1 corresponding to the pollutant concentration of the outdoor air monitored to the body controller through the LIN signal. The body controller transmits the first pollution index C1 to the in-vehicle host. The in-vehicle host compares the first pollution index C1 with the air pollution index (C2, C3, C4, C5). If C1 < C2, the in-vehicle host displays that the outdoor air quality is excellent; if C2 ≤ C1 < C3, the host displays that the outdoor air quality is good; if C3 ≤ C1 < C4, the host displays that the outdoor air quality is medium; if C4 ≤ C1 < C5, the host displays that the outdoor air quality is poor; if C5 ≤ C1, the host displays that the outdoor air quality is severely polluted. The display logic of the indoor air quality is the same and will not be elaborated here.

[0137] When the user does not turn on the air conditioner, if the outdoor air quality is excellent or good, the in-vehicle host will compare the outdoor and indoor air quality. If the outdoor air quality is better than the indoor air quality (C1 < C6), the in-vehicle host will send a switching to external circulation instruction to the body controller. After the body controller receives the switching instruction, it will automatically switch the air conditioner circulation mode to the external circulation mode to increase the indoor air circulation, reduce the indoor carbon dioxide concentration and improve the indoor air quality at the same time; otherwise, it will switch the air conditioner mode to the internal circulation state.

[0138] When the user turns on the air conditioner and the air conditioner is in the external circulation mode, if the air quality outside the vehicle is excellent or good, the in-vehicle host will compare the air quality inside and outside the vehicle. If the air quality outside the vehicle is better than that inside the vehicle (C1 < C6), the air conditioner will remain in the external circulation state; if the air quality outside the vehicle is lower than that inside the vehicle (C1 ≥ C6), the air conditioner will be switched to the internal circulation state, and at the same time, the host will pop up a window to prompt the user that "the air conditioner has been switched to the internal circulation due to poor air quality outside the vehicle".

[0139] When the user turns on the air conditioner and the air conditioner is in the internal circulation mode, if the air quality outside the vehicle is not excellent or good, regardless of whether the air quality inside the vehicle is better than that outside the vehicle, the air conditioner mode will remain in the internal circulation state. If the air quality outside the vehicle is excellent or good, the in-vehicle host will compare the air quality parameters inside and outside the vehicle. If the air quality outside the vehicle is better than that inside the vehicle, the in-vehicle host will send a switching-to-external-circulation instruction to the body controller. After receiving the switching instruction, the body controller will automatically switch the air conditioner circulation mode to the external circulation mode to improve the air quality inside the vehicle, and at the same time, the host will pop up a window to prompt the user that "the air conditioner has been switched to the external circulation due to poor air quality inside the vehicle". If the air quality inside the vehicle is better than that outside the vehicle, the air conditioner circulation mode will remain in the internal circulation.

[0140] This application is an active air purification technology that starts working before the air enters the vehicle's cockpit, improving the air purification effect, enhancing the air quality in the cockpit, and being beneficial to the customer's physical health.
