[0002] Drivers in coastal cities need to change their driving habits when driving in areas with heavy sandstorms and pay attention to the condition of their air filters. A clogged filter can lead to insufficient air intake, reduced power, increased carbon buildup, and higher fuel consumption. If the filter is not replaced for a long time, it will age and deteriorate faster, increasing the risk of engine seizure. Especially in desert off-roading, dusty roads, or traversing uninhabited areas, engine seizure and breakdowns can have very serious consequences, affecting driving safety. Summary of the Invention
[0003] The purpose of this application is to provide a method, device, equipment, medium, and program product for identifying and controlling vehicle filter element failures, in order to solve the problem of severe clogging of existing vehicle air filters affecting driving safety.

[0005] In the above implementation process, the embodiments of this application acquire environmental parameters and filter element pressure difference; determine whether the filter element is faulty based on the environmental parameters and filter element pressure difference; if the filter element is faulty, acquire the fault type; determine the filter element is faulty based on the set fault judgment rules; perform fault handling based on the set processing rules combined with the fault type; preliminarily determine whether the filter element is normal based on the environmental parameters and filter element pressure difference, and if it is not normal, further identification is used to determine what kind of fault the filter element has experienced, and the fault is reconfirmed to minimize false alarms caused by air pressure disturbances; a warning can be issued when the air filter element is severely clogged or corroded, aged and damaged, reminding the driver to replace it in time, thereby improving driving safety and fuel economy.
[0006] Furthermore, the acquisition of environmental parameters includes: Environmental parameters are calibrated based on vehicle speed, altitude, ambient temperature, and ambient humidity.
[0007] During the above process, when the filter element is working normally, the pressure difference of the filter element will be stable within a specific range. The range of this range will fluctuate with the changes of many factors, including vehicle speed, altitude, air temperature, and ambient humidity.
[0008] Furthermore, obtaining the filter element pressure difference includes: The first air pressure is obtained by detecting the air pressure before it enters the air filter using the first air pressure sensor. The second air pressure is obtained by detecting the air pressure after passing through the air filter using a second air pressure sensor. The pressure difference of the filter element is calculated based on the first and second air pressures.
[0009] During the above process, the filter element clogging status can be determined based on the pressure difference of the filter element.
[0010] Furthermore, the step of determining whether the filter element is faulty based on environmental parameters and filter element pressure difference includes: If ΔP∈K* [P_Low~ P_Up], then the filter element is not faulty; Where ΔP is the filter element pressure difference, K is the environmental parameter; K*P_Low and K*P_Up are the theoretical lower and upper boundaries of the filter element pressure difference when the filter element is working normally under specific conditions, respectively. If P∉K* [P_Low~ P_Up], then the filter element has malfunctioned; obtain the malfunction type.
[0011] In the above implementation process, obtaining the fault type can help determine the fault situation.
[0012] Furthermore, obtaining the fault type includes: Define a fault code; the default value for this fault code is 0. When ΔP > K*P_Up, set the fault code to the first value to indicate that the filter is clogged; When ΔP < K*P_Low, set the fault code to the second value to indicate that the filter element is damaged; where neither the first nor the second value is 0.
[0013] In the above implementation process, obtaining the fault type can help determine the fault situation.
[0014] Furthermore, determining that the filter element is faulty based on the set fault judgment rules includes: Periodically run system software; If the fault code is equal to the fault code value of the previous running cycle of the system software and the fault code is not equal to 0; And, engine ignition or vehicle speed exceeding the set speed value; When the time exceeds the set time threshold, a fault is detected, the logic proceeds to the next step, and the counter count is automatically incremented by 1.
[0015] In the above process, it is confirmed that the filter element is indeed faulty, so as to avoid misjudgment and ensure the accuracy of identification.
[0016] Furthermore, it also includes: If no fault is detected, return to the filter element pressure difference acquisition stage and restart the logic judgment.

It should be understood that the following drawings only show some embodiments of this application and should not be regarded as a limitation of the scope.

Detailed Implementation
[0028] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.
[0029] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions.
[0030] Please refer to Figure 1 , Figure 1This is a flowchart illustrating a method for identifying and controlling vehicle filter element malfunctions, provided in an embodiment of this application. (Refer to...) Figure 1 The methods for identifying and controlling filter element failures in this vehicle include: 100. Obtain environmental parameters and filter element pressure difference.
[0031] For details, please refer to Figure 2 Outside air passes through the air filter at position A, then through position B, and is finally drawn into the engine to participate in fuel combustion. Air pressure sensors are installed at both positions A and B to monitor the filtration effect of the air filter. Under normal circumstances, the air pressure Pa at A will be slightly lower than the ambient atmospheric pressure, but higher than the air pressure Pb at B.
[0032] 110. Based on vehicle speed, altitude, ambient temperature, and ambient humidity, calibrate environmental parameters.
[0033] It is understandable that environmental parameters refer to a correction coefficient calculated based on real-time environmental conditions. When the filter element is working normally, the difference between the air pressure Pa at point A and the air pressure Pb at point B will be stable within a specific range. However, the range of this range will fluctuate with changes in many factors, such as vehicle speed V, altitude H, air temperature T, and ambient humidity RH.
[0034] The air pressure at the engine intake varies at different vehicle speeds, the air concentration varies at different altitudes, the atmospheric pressure varies at different ambient temperatures, and the air flow varies at different humidity levels. Based on these factors, calibration sampling was conducted under different environments, and the functional relationship between the environmental parameter K and V / H / T / RH was obtained through inductive calculation: K=f(v,h,t,RH).
[0035] 120. The first air pressure is obtained by detecting the air pressure before it enters the air filter using the first air pressure sensor.
[0036] Specifically, a first air pressure sensor is installed at location A to monitor the air pressure (Pa) before it passes through the air filter.
[0037] 130. The second air pressure is obtained by detecting the air pressure after passing through the air filter using the second air pressure sensor.
[0038] Specifically, a second air pressure sensor is installed at location B to monitor the air pressure Pb after it has passed through the air filter.
[0039] 140. The pressure difference of the filter element is calculated based on the first air pressure and the second air pressure.
[0040] For example, the filter pressure difference ΔP generated by the air filter element is Pa-Pb. As the air filter element filters more dust, its blockage will intensify and its ventilation performance will decrease, resulting in the filter pressure difference ΔP becoming larger and larger. If the filter element is blocked for a long time without maintenance, it may corrode, age, or even break, at which point ΔP will become very small.
[0041] 200. Determine if the filter element is faulty based on environmental parameters and filter element pressure difference.
[0042] 210. If ΔP∈K* [P_Low~ P_Up], then the filter element is not faulty.
[0043] Where ΔP is the filter element pressure difference, K is the environmental parameter; K*P_Low and K*P_Up are the theoretical lower and upper boundaries of the filter element pressure difference when the filter element is working normally under specific conditions.
[0044] 220. If P∉K* [P_Low~ P_Up], then the filter element has failed. Obtain the fault type.
[0045] Under normal circumstances, ΔP ∈ K* [P_Low ~ P_Up], meaning the filter element pressure difference is within this range. Here, K*P_Low and K*P_Up are the theoretical lower and upper boundaries of the filter element pressure difference ΔP when the filter element is working normally under specific conditions. If P ∉ K* [P_Low ~ P_Up], it indicates that the filter element has malfunctioned, and the following logical arbitration process will begin.
[0046] 300. If the filter element is faulty, obtain the fault type.
[0047] It is understandable that filter cartridge failure can have many causes. Therefore, it is important to obtain the specific type of failure so that appropriate troubleshooting measures can be taken accordingly.
[0048] 310. Define fault codes; the default value for a fault code is 0.
[0049] 320. When ΔP > K*P_Up, set the fault code to the first value to indicate that the filter element is clogged.
[0050] 330. When ΔP < K*P_Low, set the fault code to the second value to determine that the filter element is damaged; where neither the first nor the second value is 0.
[0051] For example, a fault code ErrCode is defined with a default value of 0. When ΔP > K*P_Up, ErrCode = 1, indicating that the filter element is clogged. When ΔP < K*P_Low, ErrCode = 2, indicating that the filter element is damaged.
[0052] Understandably, filter clogging occurs when the pores of the filter element are filled with impurities, leading to reduced flow rate, excessively low negative pressure in the equipment, and in severe cases, even equipment shutdown. In water purifiers, this manifests as reduced water output and decreased pressure; in automotive air filters, it manifests as increased intake resistance, insufficient engine air intake, and affected power output. Causes include excessively high concentrations of dust-laden gas, excessively fine dust particles, sticky dust, easy absorption of moisture, and leaks in the filter cartridge dust collector's outer shell, allowing humid air to enter. When filter clogging is detected, the filter element needs to be cleaned.
[0053] Understandably, a damaged filter element—that is, a torn or perforated filter element—leads to air leakage or the direct release of unfiltered gas, significantly reducing the equipment's filtration efficiency. When a damaged filter element is detected, it should be replaced promptly.
[0054] 400. Based on the established fault diagnosis rules, determine that the filter element is faulty.
[0055] Specifically, the system software runs periodically; the fault code is equal to the fault code value of the previous running cycle of the system software and the fault code is not equal to 0, and the engine ignition or vehicle speed is greater than the set vehicle speed value; when the fault code is equal to the fault code value of the previous running cycle of the system software and the fault code is not equal to 0, and the time for engine ignition or vehicle speed to be greater than the set vehicle speed value exceeds the set time threshold, a fault is determined to have occurred, the logic proceeds to the next step, and the counter count is automatically incremented by 1.
[0056] For example, the system software runs periodically. When the following three conditions are met simultaneously, a fault is determined to have occurred, the logic proceeds to the next step, and the counter N is incremented by 1: 1)ErrCode=Last Value, and ErrCode≠0; 2) Engine ignition, or vehicle speed V > 3 km / h; 3) Both of the above conditions must be met simultaneously for more than 5 minutes (TBD).
[0057] The Last Value here refers to the ErrCode value of the system software in the previous runtime cycle. Condition 1 is significant in ensuring the stability of the fault. If the faults in two adjacent software cycles are different, it indicates that the fault has abruptly changed, and there is a possibility of misidentification, thus lacking the preconditions for taking further measures.
[0058] When the engine is ignited and running, or the vehicle is in motion, the engine will operate actively or passively. Only then will a faulty filter affect the engine. Condition 2 is to prevent blindly troubleshooting when the engine is not running.
[0059] Condition 3 can ensure the continuity of the fault and further prevent false alarms and mishandling.
[0060] If no fault occurs, the system returns to the filter element pressure difference acquisition stage and restarts the logic judgment. That is, if the above three conditions are not met, the system returns to the filter element pressure difference ΔP calculation stage and restarts the logic judgment.
[0061] When the counter N > 10, it means that the current fault has been triggered multiple times or has accumulated for a long enough time. At this time, the fault is reliable and it is necessary to take corresponding measures. Then proceed to the next step and take different fault handling measures based on different faults.
[0062] 500. Handle faults based on the set processing rules and the fault type.
[0063] Optionally, when the fault code is the first value, the instrument panel will issue an alarm and prompt for maintenance; limit the engine's operating power; store the fault code; and remotely push fault information to the terminal.
[0064] For example, when ErrCode=1, fault handling measure 1 is taken: 1) The instrument issues an alarm and displays the message "Air filter clogged, please have it checked immediately!"; 2) The engine operates at limited power to reduce the intake air volume; 3) Store fault codes; Remotely push fault information to the terminal and mobile APP.
[0065] Optionally, when the fault code is the second value, the instrument will issue an alarm and prompt for maintenance; store the fault code; limit the engine's operating power until a set time is reached; and remotely push fault information to the terminal.
[0066] For example, when ErrCode=2, fault handling measure 2 is taken: 1) The instrument alarm sounds and displays the message "Air filter damaged, please have it repaired immediately!"; 2) Store fault codes; 3) Run the engine at limited power for 30 minutes, then turn it off; 4) Remotely push fault information to the terminal and mobile APP.
[0067] As described above, this application embodiment obtains environmental parameters and filter element pressure difference; determines whether the filter element is faulty based on the environmental parameters and filter element pressure difference; if the filter element is faulty, obtains the fault type; determines that the filter element is faulty based on the set fault judgment rules; performs fault handling based on the set processing rules combined with the fault type; initially judges whether the filter element is normal based on the environmental parameters and filter element pressure difference; if it is not normal, further identification is used to determine what kind of fault the filter element has experienced, and the fault is reconfirmed to minimize false alarms caused by air pressure disturbances; it can issue a warning when the air filter element is severely clogged or corroded, aged and damaged, reminding the driver to replace it in time, improving driving safety and fuel economy.
[0068] Understandably, internal combustion engines require a large amount of air to operate. Excessive dust and other solid particles in the air can affect fuel combustion and even cause irreversible engine damage such as cylinder scoring. Therefore, passenger cars equipped with internal combustion engines are fitted with an air filter at the engine intake. Air filters are consumables and need to be replaced regularly. The replacement cycle varies depending on the engine's operating environment and frequency of use. For the same mileage, air filter replacement is less frequent in coastal areas with less wind and sand and good air quality, and more frequent in Northwest China, Inner Mongolia, or other environments with poor air quality.
[0069] The steps described above are not strictly performed in the order of their numbers; they should be understood as a whole.
