Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a method, apparatus, and vehicle for treating an air filter. Background Technology

[0002] A vehicle air filter is a device that removes particulate impurities from the air. Its function is to filter out dust, sand, and other particles suspended in the air, preventing them from entering the engine and affecting its performance. The filter element is the part of the air filter that performs this filtering function. Currently, many counterfeit and substandard filter elements exist on the market. These products have serious quality problems, cannot effectively filter out impurities in the air, and failure to replace them in a timely manner will affect the engine's lifespan, causing losses to users.

[0003] In related technologies, anti-counterfeiting barcodes are placed on the filter element, and users can scan the barcode with relevant software on their mobile phones to verify the authenticity of the filter element. However, anti-counterfeiting barcodes are easily copied, resulting in poor anti-counterfeiting effectiveness. Alternatively, an anti-counterfeiting chip is added to the filter element, and users can use a relevant anti-counterfeiting identification system on their mobile phones to identify the authenticity of the filter element based on the feedback from the system. However, this method is costly, and the anti-counterfeiting identification system is easily counterfeited, leading to failure in filter element authenticity verification. Furthermore, these methods do not promptly remind users to prepare filter elements, resulting in untimely filter replacement and potential damage to the engine. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, one objective of this application is to provide a method, apparatus, and vehicle for processing air filters, so as to inspect the quality of the controller and filter element in the air filter, and to replace and maintain the filter element in a timely manner, so as to avoid damage to the vehicle engine due to filter element quality problems and untimely replacement.

[0006] To achieve the above objectives, a first aspect of this application proposes a method for processing an air filter, wherein the air filter includes a controller and a filter element. The method includes: verifying the controller and the filter element using a verification code, a first encryption code, and a second encryption code, respectively; if both the controller and the filter element pass verification, processing the air filter based on the vehicle's mileage, the air filter's pressure, and the number of maintenance cycles; if at least one of the controller or the filter element fails verification, issuing a first prompt message to indicate controller damage and / or low filter element quality.

[0007] According to one embodiment of this application, the verification of the controller and the filter element using a verification code, a first encryption code, and a second encryption code includes: encrypting the verification code and the ID code of the controller to obtain a third encryption code, and encrypting the verification code and the ID code of the filter element to obtain a fourth encryption code; if the third encryption code is consistent with the first encryption code and the fourth encryption code is consistent with the second encryption code, then it is determined that both the controller and the filter element have passed verification; if the third encryption code is inconsistent with the first encryption code, and / or the fourth encryption code is inconsistent with the second encryption code, then it is determined that at least one of the controller and the filter element has failed verification.

[0008] According to one embodiment of this application, the verification code and the ID code of the controller are encrypted using the MD5 algorithm or the SHA256 algorithm, and the verification code and the ID code of the filter are encrypted using the MD5 algorithm or the SHA256 algorithm.

[0009] According to one embodiment of this application, processing the air filter based on the vehicle's mileage, the air filter's pressure, and the number of maintenance cycles includes: comparing the pressure with a first pressure threshold; if the pressure is greater than the first pressure threshold, determining a first processing method for the air filter based on the mileage, the pressure, and the number of maintenance cycles; otherwise, issuing a second prompt message to indicate pressure failure; if the first processing method requires filter replacement, determining a second processing method for the air filter based on the mileage, the pressure, and the number of maintenance cycles; otherwise, determining a third processing method for the air filter based on the mileage, the pressure, and the number of maintenance cycles; if the second processing method requires timely filter replacement, issuing a third prompt message to indicate timely filter replacement; otherwise, issuing a fourth prompt message to indicate advance preparation of filter replacement; if the third processing method requires maintenance, performing maintenance on the air filter and incrementing the maintenance cycle by 1; otherwise, returning to the step of comparing the pressure with the first pressure threshold.

[0010] According to one embodiment of this application, determining a first treatment method for the air filter based on the mileage, the pressure, and the number of maintenance cycles includes: comparing the mileage with a first mileage threshold; if the mileage is greater than the first mileage threshold, then determining that the first treatment method requires filter replacement; otherwise, comparing the pressure with a second pressure threshold, wherein the second pressure threshold is greater than the first pressure threshold; if the pressure is greater than the second pressure threshold, then determining that the first treatment method requires filter replacement; otherwise, further comparing the pressure with a third pressure threshold, wherein the third pressure threshold is greater than the first pressure threshold and less than the second pressure threshold; if the pressure is greater than or equal to the third pressure threshold, then determining that the first treatment method does not require filter replacement; otherwise, comparing the number of maintenance cycles with a number of maintenance cycles threshold; if the number of maintenance cycles is greater than the number of maintenance cycles threshold, then determining that the first treatment method requires filter replacement; otherwise, determining that the first treatment method does not require filter replacement.

[0011] According to one embodiment of this application, the step of obtaining a second processing method based on the mileage, the pressure, and the number of maintenance includes: comparing the mileage with a second mileage threshold and comparing the pressure with a second pressure threshold, wherein the second mileage threshold is greater than a first mileage threshold; if the mileage is greater than the second mileage threshold or the pressure is greater than the second pressure threshold, then the second processing method is determined to require timely replacement of the filter element; otherwise, the second processing method is determined to require no timely replacement of the filter element.

[0012] According to one embodiment of this application, the maintenance of the air filter includes: sending an automatic dust removal command to the air filter after the vehicle's engine stops; determining whether there is pressure fluctuation in the air filter within a first preset time before dust removal; if there is fluctuation, sending a stop automatic dust removal command to the air filter and issuing a third prompt message to indicate a malfunction in the air filter's backflushing system; otherwise, controlling the backflushing system to operate for a second preset time, and then sending a stop automatic dust removal command to the air filter.

[0013] According to one embodiment of this application, the first preset time is 5-15s, and the second preset time is 50-70s.

[0014] To achieve the above objectives, a second aspect of this application provides an air filter processing device, wherein the air filter includes a controller and a filter element, comprising: a verification module (10) for verifying the controller and the filter element using a verification code, a first encryption code, and a second encryption code respectively; a processing module (20) for processing the air filter based on the mileage of the vehicle where the air filter is located, the pressure of the air filter, and the number of maintenance cycles when both the controller and the filter element pass verification; and a prompting module (30) for issuing a first prompting message when at least one of the controller and the filter element fails verification, to indicate that the controller is damaged and / or the filter element is of low quality.

[0015] To achieve the above objectives, a third aspect of this application provides a vehicle comprising an air filter and a processing device for the air filter as described in the second aspect of this application.

[0016] The air filter processing method, apparatus, and vehicle of this application improve the reliability of air filter quality verification by verifying the controller and filter element in the air filter separately. At the same time, different processing methods for the air filter are determined according to the vehicle's mileage, air filter pressure, and maintenance frequency, which enables timely maintenance and replacement of the vehicle's filter element. When the filter element is about to be replaced, the user is reminded to prepare the filter element in time, avoiding damage to the vehicle's piston mechanism due to untimely replacement or maintenance or the use of inferior filter elements.

[0017] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0026] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] The following description, with reference to the accompanying drawings, describes a method, apparatus, and vehicle for processing air filters according to embodiments of the present invention.

[0028] Figure 1 This is a flowchart of an air filter processing method according to an embodiment of this application. It should be noted that the air filter processing method implemented in this application can be applied to vehicles.

[0029] like Figure 1 As shown, the air filter's treatment method may include:

[0030] S110 uses a verification code, a first encryption code, and a second encryption code to verify the controller and the filter element, respectively.

[0031] Specifically, the verification code, the first encryption code, and the second encryption code can be output by the air filter. The verification code can be a random code, such as an 8-bit hexadecimal random number.

[0032] Furthermore, the air filter and the vehicle's ECU (Electronic Control Unit) can communicate via a CAN (Controller Area Network) bus. During controller and filter verification, the controller in the air filter sends a verification code to the ECU, along with a first encryption code and a second encryption code that have been encrypted using the controller's encryption algorithm. The first encryption code uses the encryption algorithm corresponding to the controller to encrypt the verification code, while the second encryption code uses the encryption algorithm corresponding to the filter.

[0033] It is understandable that there is a correspondence between the verification code output by the air filter and the first and second encryption codes; different verification codes correspond to different first and second encryption codes. Different air filters output different verification codes, first encryption codes, and second encryption codes.

[0034] As an example, the correspondence between different verification codes, first encryption codes, and second encryption codes output by the air filter can be stored in a database in advance. When it is necessary to verify the controller and filter, the air filter can randomly select a set of verification codes, first encryption codes, and second encryption codes from the database to verify the controller and filter.

[0035] As another example, the air filter can periodically generate random verification codes, along with corresponding first and second encryption codes, to verify the controller and filter element. For instance, when the air filter is operating, the controller can send an 8-digit hexadecimal random number to the ECU every 5 minutes as plaintext for verifying the authenticity of the intelligent air filter controller. The controller will also send this plaintext as 8-digit hexadecimal ciphertext calculated using two preset encryption algorithms corresponding to the controller and filter element, respectively—the first and second encryption codes.

[0036] S120: If both the controller and the filter element pass the verification, the air filter will be processed according to the vehicle's mileage, the air filter's pressure, and the number of maintenance cycles.

[0037] Specifically, if both the controller and the filter element pass the verification, it means that the controller and the filter element in the air filter are of qualified quality. On this basis, the vehicle's mileage, the air filter pressure and maintenance frequency are further obtained to determine whether the air filter needs further operation, such as replacing the filter element or performing maintenance on the air filter.

[0038] S130, if at least one of the controller or filter element fails verification, a first prompt message is issued to indicate that the controller is damaged and / or the filter element is of low quality.

[0039] Optionally, if at least one of the controller or filter fails to be verified, a notification message indicating that the controller is damaged and / or the filter is of low quality can be sent to the user via their mobile phone or vehicle display screen.

[0040] This air filter processing method improves the reliability of air filter quality verification by verifying both the controller and the filter element separately. Furthermore, it determines different processing methods for the air filter based on vehicle mileage, air filter pressure, and maintenance frequency. This allows for timely maintenance and replacement of the vehicle's filter element, and reminds users to prepare replacement filters when they are due, preventing damage to the vehicle's piston mechanism due to untimely replacement or maintenance, or the use of inferior filter elements.

[0041] Figure 2 This is a flowchart of a processing method for an air filter according to a specific embodiment of this application.

[0042] According to one embodiment of the present invention, such as Figure 2 As shown, the controller and the filter element are verified using a verification code, a first encryption code, and a second encryption code, respectively, including the following steps:

[0043] S210 encrypts the verification code and the controller's ID code to obtain the third encryption code, and encrypts the verification code and the filter's ID code to obtain the fourth encryption code.

[0044] Optionally, the ID codes of the controller and filter element in the air filter can be obtained by looking up the vehicle configuration table. The air filter can automatically read the controller ID and filter element ID from the vehicle configuration table, or the user can manually enter them.

[0045] The ECU can use an encryption algorithm to encrypt the controller's ID code based on the verification code output by the air filter, thus obtaining a third encryption code. It can also use an encryption algorithm to encrypt the filter element's ID code based on the verification code output by the air filter, thus obtaining a fourth encryption code.

[0046] In this embodiment, upon obtaining the first encryption key, the controller needs to use a corresponding encryption algorithm to encrypt the verification code and the controller's ID code; upon obtaining the second encryption key, the controller needs to use a corresponding encryption algorithm to encrypt the ID code of the verification code filter.

[0047] S220, if the third encryption code is the same as the first encryption code, and the fourth encryption code is the same as the second encryption code, then it is determined that both the controller and the filter element have passed the verification.

[0048] Specifically, the controller in the air filter sends a verification code to the vehicle's ECU at preset intervals, and at the same time sends a first encryption code to the ECU. When the ECU receives the verification code, it uses an encryption algorithm to encrypt the verification code to obtain a third encryption code. When the first encryption code sent by the controller matches the third encryption code obtained by the ECU, it means that the controller has successfully verified the code.

[0049] When the air filter controller verifies the filter as genuine, the vehicle's ECU reads the filter's ID code and second encryption code sent by the controller. The vehicle's ECU generates a fourth encryption code based on the verification code and the filter's ID code. When the second and fourth encryption codes match, it indicates that the filter has passed verification.

[0050] Specifically, when verifying the controller and filter element, for qualified controllers and filter elements, the first encryption cipher and the third encryption cipher are consistent with each other, and the second encryption cipher and the fourth encryption cipher are consistent with each other, after being encrypted with the verification code using an encryption algorithm. For unqualified controllers and filter elements, the third encryption cipher and the fourth encryption cipher cannot be calculated using the encryption algorithm, or the third encryption cipher calculated using the encryption algorithm is inconsistent with the first encryption cipher, and the fourth encryption cipher is inconsistent with the second encryption cipher.

[0051] For example, suppose the air filter randomly outputs a verification code of 001 when verifying the controller and filter element. The corresponding first and second encryption codes are 0011 and 0012, respectively. A preset encryption algorithm is used to encrypt the verification code 001 with the controller ID and the verification code 001 with the filter element ID, resulting in encrypted third and fourth encryption codes. If the air filter obtains the third encryption code as 0011 and the fourth encryption code as 0012, the ECU determines that both the controller and filter element have passed verification. By encrypting the controller and filter element with the randomly output verification code from the air filter and comparing the third and fourth encryption codes with the first and second encryption codes to verify their qualification, the authenticity of the controller and filter element can be effectively prevented from being tampered with by criminals during the verification process, thus avoiding the difficulty in distinguishing genuine and counterfeit filters.

[0052] S230, if the third encryption code is inconsistent with the first encryption code, and / or the fourth encryption code is inconsistent with the second encryption code, then at least one of the controller and the filter element is determined to have failed verification.

[0053] According to one embodiment of the present invention, the verification code and the ID code of the controller can be encrypted using the MD5 algorithm or the SHA256 algorithm, and the verification code and the ID code of the filter can be encrypted using the MD5 algorithm or the SHA256 algorithm.

[0054] Optionally, one of the MD5 and SHA256 algorithms can be randomly selected to encrypt the verification code and the controller ID, or one of the encryption algorithms can be specified to encrypt the verification code and the controller ID.

[0055] Alternatively, different batches of controllers and filter elements may use different encryption algorithms, or the same batch of controllers and filter elements may use the same encryption algorithm.

[0056] Furthermore, other hashing or encryption algorithms can be used to encrypt the verification code and the ID code of the filter.

[0057] Figure 3 This is a flowchart of a processing method for an air filter according to another specific embodiment of this application.

[0058] According to one embodiment of the present invention, such as Figure 3 As shown, the air filter is treated based on the vehicle's mileage, air filter pressure, and maintenance frequency, including the following steps:

[0059] S310, compare the pressure with a first pressure threshold.

[0060] Specifically, the pressure of the air filter can be obtained by collecting the output value of the air filter's pressure sensor.

[0061] Optionally, a sampling period can be set to collect the pressure value once every sampling period. For example, the sampling period can be 10 seconds, and the pressure value output by the pressure sensor of the air filter can be acquired once every 10 seconds.

[0062] S320: If the pressure is greater than the first pressure threshold, the first treatment method for the air filter is determined based on the mileage, pressure and maintenance frequency; otherwise, a second prompt message is issued to indicate pressure failure.

[0063] Specifically, when the pressure exceeds a first pressure threshold, the vehicle's mileage, air filter pressure, and maintenance frequency are acquired. When these parameters meet a first preset condition, a first treatment method for the air filter is determined. The first preset condition is a threshold condition for each of the mileage, air filter pressure, and maintenance frequency, or a combination of these threshold conditions. For example, the first preset condition could be that the mileage exceeds 80% of the maximum mileage, or it could be set as needed. The first preset condition does not require specific air filter pressure or maintenance frequency.

[0064] Optionally, if the pressure remains above a first threshold for a first duration, a first handling method for the pressure is determined based on mileage, pressure, and maintenance frequency; otherwise, a second prompt message is issued to indicate pressure failure. Pressure failure indicates damage to the air filter's pressure sensor, prompting a warning of pressure sensor malfunction. Determining whether the current pressure value remains above the first threshold for the first duration avoids interference from pressure fluctuations in the judgment.

[0065] S330: If the first treatment method requires filter replacement, the second treatment method for the air filter is determined based on mileage, pressure, and maintenance frequency; otherwise, the third treatment method for the air filter is determined based on mileage, pressure, and maintenance frequency.

[0066] Specifically, if the first treatment method requires filter replacement, when the mileage, pressure, and maintenance frequency meet the second preset conditions, the second treatment method for the air filter is determined, wherein the second preset conditions are the threshold conditions for mileage, pressure, and maintenance frequency, or a combination of the threshold conditions for each. Otherwise, the third treatment method for the air filter is determined based on the mileage, pressure, and maintenance frequency.

[0067] For example, the second preset condition could be a mileage greater than 100% of the maximum mileage and / or a pressure exceeding 100% of the final flow resistance. The second preset condition can also be set as needed. For instance, when the vehicle's mileage is greater than 100% of the maximum mileage, the second preset condition is met; or when the vehicle's mileage is less than the maximum mileage and the pressure exceeds 100% of the final flow resistance, the second preset condition is also met, thereby determining the second treatment method for the air filter.

[0068] Furthermore, if the first treatment method requires filter replacement, then when the mileage, pressure, and maintenance frequency meet the third preset condition, a third treatment method for the air filter is determined, wherein the third preset condition is a threshold condition for each of the mileage, pressure, and maintenance frequency, or a combination of the respective threshold conditions.

[0069] S340, if the second processing method requires timely replacement of the filter element, a third prompt message is issued to remind the user to replace the filter element in time; otherwise, a fourth prompt message is issued to remind the user to prepare the filter element in advance.

[0070] Specifically, the third reminder message is a reminder to the user to replace the filter in a timely manner, which can be delivered via the user's mobile phone or the vehicle's display screen.

[0071] Optionally, when it is determined that the second treatment for the air filter is to replace the filter element in a timely manner, that is, when the result of the vehicle's mileage and pressure judgment is that the filter element has reached its maximum limit of use, the user needs to be reminded to replace the filter element in a timely manner.

[0072] Understandably, the vehicle's mileage increases during the use of the filter. When the vehicle's mileage meets the first preset condition but not the second preset condition, that is, when the vehicle's mileage is between the first and second preset conditions, a fourth prompt message is issued to remind the user to prepare the filter in advance.

[0073] For example, the mileage is greater than 80% of the maximum mileage in the first preset condition and greater than 100% of the maximum mileage in the second preset condition. That is, when the vehicle's mileage is between 80% and 100% of the maximum mileage, the user is reminded to prepare the filter in time so that it can be replaced when needed.

[0074] S350, if the third processing method requires maintenance, then perform maintenance on the air filter and increment the maintenance count by 1; otherwise, return to the step of comparing the pressure with the first pressure threshold.

[0075] Understandably, when it is determined that the air filter does not need to be replaced, and the vehicle's mileage, pressure, and maintenance frequency meet the third preset condition, the third treatment method for the air filter is determined. The third preset condition is a threshold condition for each of the mileage, pressure, and maintenance frequency, or a combination of the threshold conditions. Otherwise, the process returns to the step of comparing the pressure with the first pressure threshold.

[0076] For example, the third preset condition could include mileage exceeding 30% of the maximum mileage. When the vehicle's mileage exceeds 30% of the maximum mileage, the air filter is maintained, and the number of maintenance visits and the corresponding mileage are recorded. Alternatively, the third preset condition could include the mileage corresponding to the last maintenance visit and the current mileage. For instance, if the last maintenance visit was the second visit, corresponding to 10,000 km, and the vehicle requires air filter maintenance every 5,000 km, then the current third preset condition is mileage exceeding 15,000 km. When the vehicle's mileage exceeds 15,000 km, maintenance is performed.

[0077] Figure 4 This is a flowchart of a processing method for an air filter according to another specific embodiment of this application.

[0078] According to one embodiment of the present invention, such as Figure 4 As shown, based on mileage, pressure, and maintenance frequency, the first treatment method for the air filter is determined, including the following steps:

[0079] S410 compares the mileage driven with a first mileage threshold.

[0080] Optionally, the first mileage threshold can be 80% of the maximum mileage, wherein the maximum mileage can be the cumulative mileage of the vehicle when the vehicle's filter reaches its usage limit.

[0081] S420 If the mileage exceeds the first mileage threshold, the first treatment is to replace the filter element; otherwise, the pressure is compared with the second pressure threshold, where the second pressure threshold is greater than the first pressure threshold.

[0082] Optionally, the second pressure threshold can be 100% of the final flow resistance.

[0083] If the mileage exceeds the first mileage threshold, it means that the vehicle is about to reach the limit mileage for replacing the filter, that is, the maximum mileage.

[0084] For example, assuming the vehicle's maximum mileage is 60,000 km, and the first mileage threshold is 80% of the maximum mileage, which is 48,000 km, if the vehicle's mileage is 50,000 km, which is above the first mileage threshold, the first course of action for the air filter is to replace the filter element promptly. If the vehicle's mileage is 30,000 km, which is below the first mileage threshold, then the pressure is compared with a second pressure threshold.

[0085] S430, if the pressure is greater than the second pressure threshold, the first treatment is to replace the filter element; otherwise, the pressure is further compared with the third pressure threshold, where the third pressure threshold is greater than the first pressure threshold and less than the second pressure threshold.

[0086] Optionally, the third pressure threshold can be 70% of the final flow resistance.

[0087] When the vehicle's mileage is less than or equal to the first mileage threshold and the pressure is greater than the second pressure threshold, the first course of action is to replace the filter. When the vehicle's mileage is less than or equal to the first mileage threshold and the pressure is less than or equal to the second pressure threshold, the pressure is compared with the third pressure threshold.

[0088] S440, if the pressure is greater than or equal to the third pressure threshold, then the first treatment method is determined to be that the filter element does not need to be replaced; otherwise, the maintenance number is compared with the number threshold.

[0089] When the vehicle's mileage is less than or equal to the first mileage threshold, the pressure is greater than or equal to the third pressure threshold, and less than or equal to the second threshold, the corresponding first treatment is that the filter element does not need to be replaced. In other words, if the vehicle's mileage is within the normal driving range and the pressure value is normal, then the filter element does not need to be replaced.

[0090] S450: If the number of maintenance operations exceeds the threshold, the first treatment method is determined to be that the filter element needs to be replaced; otherwise, the first treatment method is determined to be that the filter element does not need to be replaced.

[0091] When the vehicle's mileage is less than or equal to the first mileage threshold and the pressure is less than the third pressure threshold, the need to replace the filter element is determined based on whether the number of maintenance cycles is greater than the number of maintenance cycles. The number of maintenance cycles can be set according to different filter elements.

[0092] Figure 5This is a flowchart of a processing method for an air filter according to another specific embodiment of this application.

[0093] According to one embodiment of the present invention, such as Figure 5 As shown, based on mileage, pressure, and maintenance frequency, a second treatment method is derived, including the following steps:

[0094] S510 compares the driving mileage with a second mileage threshold and the pressure with a second pressure threshold, wherein the second mileage threshold is greater than the first mileage threshold.

[0095] Optionally, the second mileage threshold can be 100% of the maximum mileage.

[0096] S520: If the mileage exceeds the second mileage threshold or the pressure exceeds the second pressure threshold, then the second treatment method is determined to require timely replacement of the filter element; otherwise, the second treatment method is determined to require no timely replacement of the filter element.

[0097] For example, when the second mileage threshold is 100% of the maximum mileage, the second pressure threshold is 100% of the final flow resistance, the mileage is greater than 100% of the maximum mileage, or the pressure is greater than 100% of the final flow resistance, it is determined that the filter needs to be replaced.

[0098] Figure 6 This is a flowchart of a processing method for an air filter according to another specific embodiment of this application.

[0099] According to one embodiment of the present invention, such as Figure 6 As shown, maintaining an air filter includes the following steps:

[0100] S610 sends an automatic dust removal command to the air filter after the vehicle's engine stops.

[0101] S620 determines whether there is pressure fluctuation in the air filter within a first preset time before dust removal.

[0102] Optionally, the pressure value of the air filter before dust removal is continuously acquired within a first preset time period. The voltage value is acquired three times in a sliding window manner. The absolute value of the difference between the three consecutive voltage values ​​is taken, and the range of the absolute value of the difference is compared with the first preset difference value to determine whether there is pressure fluctuation.

[0103] S620, if there is fluctuation, a stop automatic dust removal command is sent to the air filter and a third prompt message is issued to indicate a malfunction in the air filter's backflushing system; otherwise, the backflushing system is controlled to operate for a second preset time, after which a stop automatic dust removal command is sent to the air filter.

[0104] When the absolute values ​​of the differences are all less than the first preset difference, it indicates that the pressure fluctuation is very small, and it can be approximated as having no pressure fluctuation. The backflushing system is then controlled to operate for a second preset time, after which a stop automatic dust removal command is sent to the air filter. The second preset time is the duration for which the backflushing system operates on the air filter.

[0105] If the absolute values ​​obtained from the difference are all greater than or equal to the first preset difference, it indicates that the pressure fluctuation is large, the dust removal will be stopped, and a warning of a backflushing system failure will be issued to the user.

[0106] According to one embodiment of the present invention, the first preset time can be 5-15s, and the second preset time can be 50-70s.

[0107] Corresponding to the air filter processing methods provided in the above embodiments, one embodiment of this application also provides an air filter processing apparatus.

[0108] Figure 7 This is a schematic diagram of a processing apparatus for an air filter according to an embodiment of this application. The air filter includes a controller and a filter element. Figure 7 As shown, the air filter processing device 100 may include: a verification module 10, a processing module 20, and a prompting module 30.

[0109] Specifically, the verification module 10 is used to verify the controller and the filter element using a verification code, a first encryption code, and a second encryption code, respectively.

[0110] The processing module 20 is used to process the air filter based on the vehicle's mileage, air filter pressure, and maintenance frequency when both the controller and filter element have passed verification.
