[0002] While a car is in motion, outside air enters the passenger compartment. However, outside air contains many different particles, such as dust, pollen, soot, and abrasive particles. The car's air conditioning system absorbs these impurities through its filter, reducing the irritation to the driver's respiratory tract and making driving more comfortable. However, the air conditioning filter has a limited lifespan and needs to be replaced regularly.

[0003] Currently, replacing in-vehicle cabin air filters is a rather passive process, typically involving vehicle maintenance personnel inspecting the filter and providing recommendations for cleaning or replacement. This method relies heavily on the expertise of the maintenance personnel and is labor-intensive. Therefore, a solution is urgently needed. Summary of the Invention

[0020] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] In existing technologies, the replacement of vehicle cabin air conditioning filters is relatively passive, typically requiring vehicle maintenance personnel to inspect the filter and provide cleaning or replacement recommendations. This method relies heavily on the expertise of the maintenance personnel and incurs significant labor costs. To address this technical problem, this application provides a method for detecting the lifespan of vehicle cabin air conditioning filters in some embodiments.

[0022] In this method for detecting the lifespan of an in-vehicle air conditioning filter, the lifespan factor of the air conditioning filter can be determined based on the air quality of the vehicle's driving environment and the circulation mode of the vehicle's air conditioning system. The remaining lifespan of the air conditioning filter is calculated based on the duration of airflow at or below a specified setting, the duration of airflow above a specified setting, the lifespan factor, and the total lifespan of the air conditioning filter. Corresponding filter maintenance reminder information is then output based on the remaining lifespan of the air conditioning filter. The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0023] Figure 1 A schematic flowchart of a life testing method for an in-vehicle air conditioning filter provided as an exemplary embodiment of this application is shown below. Figure 1 As shown, the method includes:

[0024] Step 11: Determine the life factor of the air conditioner filter based on the air quality of the vehicle's driving environment and the circulation mode of the vehicle's air conditioner.

[0025] Step 12: Obtain the first duration during which the airflow of the vehicle air conditioner is less than or equal to the specified level, and the second duration during which the airflow is greater than the specified level.

[0026] Step 13: Calculate the remaining lifespan of the air conditioning filter element based on the first duration, the second duration, the lifespan factor, and the total lifespan of the vehicle air conditioning filter element.

[0027] Step 14: Output the corresponding filter maintenance reminder information based on the remaining lifespan of the air conditioner's filter.

[0028] This embodiment can be executed by an ECU (Electronic Control Unit), an on-board motion domain controller, or an on-board terminal deployed in the vehicle; this embodiment is not limited to any particular type. The following will use an ECU as an example for illustrative explanation.

[0029] Steps 11 and 12 can be executed in the order described above, or step 12 can be executed first and then step 11, or steps 11 and 12 can be executed simultaneously. This embodiment does not impose any restrictions.

[0030] In this embodiment, the ECU can determine the lifespan factor of the vehicle's air conditioning filter based on the air quality of the vehicle's driving environment and the air circulation mode of the vehicle's air conditioning system. The vehicle's driving environment may include the external environment and the interior environment of the vehicle cabin. The air circulation mode may include: internal circulation mode, external circulation mode, and internal / external circulation mode. The lifespan factor is a parameter required to calculate the remaining lifespan of the vehicle's air conditioning system.

[0031] In addition to the lifespan factor, the system can also obtain the first duration for which the vehicle's air conditioning fan speed is less than or equal to a specified level, and the second duration for which the fan speed is greater than a specified level. The specified level can be preset according to actual design requirements. The use of "first" and "second" to define the duration is only for distinguishing the obtained duration and does not restrict the length of the duration. For example, if the specified level is 4, the system can obtain a first duration of 100 hours for the vehicle's air conditioning fan speed being less than or equal to level 4, and a second duration of 90 hours for the fan speed being greater than level 4.

[0032] Based on the above steps, the remaining lifespan of the air conditioning filter can be calculated according to the first duration, the second duration, the lifespan factor, and the total lifespan of the vehicle air conditioning filter. The total lifespan can be preset based on the characteristics of the air conditioning filter itself, or it can be calibrated by the user based on the characteristics of the air conditioning filter itself.

[0033] After calculating the remaining lifespan of the air conditioning filter, corresponding filter maintenance reminders can be output based on the remaining lifespan of the filter. These reminders can be in the form of voice messages, vibration alerts, or text messages, etc., and this embodiment is not limited to any particular form. For example, the vehicle's Head Unit (HU) can output a voice message saying "Please replace the filter in time."

[0034] In this embodiment, the lifespan factor of the air conditioning filter can be determined based on the air quality of the vehicle's driving environment and the circulation mode of the vehicle's air conditioning system. Based on the duration of time the air conditioning fan speed is less than or equal to a specified setting, the duration of time the fan speed is greater than a specified setting, the lifespan factor, and the total lifespan of the air conditioning filter, the remaining lifespan of the air conditioning filter is calculated. Based on the remaining lifespan of the air conditioning filter, corresponding filter maintenance reminders are output. This implementation method allows for the calculation of the remaining lifespan of the vehicle's air conditioning filter, eliminating the need for vehicle maintenance personnel to assess the filter's lifespan, thus saving labor costs. Furthermore, it can remind passengers to maintain the filter in a timely manner based on the remaining lifespan, preventing harm to passengers' health due to decreased filter performance.

[0035] In some optional embodiments, the step 11 of the foregoing embodiments, "determining the life factor of the vehicle air conditioning filter based on the air quality of the vehicle's driving environment and the circulation mode of the vehicle's air conditioning," can be implemented based on the following steps:

[0036] Step 111: Determine the first lifespan factor of the vehicle's air conditioning system based on the air quality level of the area where the vehicle is located.

[0037] The air quality level of the vehicle's driving area can be obtained from a cloud server, which can perform big data analysis to determine the air quality level of the driving area. It's important to note that the air quality level of the vehicle's driving area is positively correlated with the first lifespan factor; in other words, the better the air quality, the higher the value of the first lifespan factor. For example, air quality levels can be categorized as excellent, lightly polluted, moderate, and heavily polluted. Based on the excellent air quality level of the driving area, the first lifespan factor of the vehicle's air conditioning system can be determined to be Y1 = 1. Based on the lightly polluted air quality level, the first lifespan factor of the vehicle's air conditioning system can be determined to be Y1 = 2. Based on the heavily polluted air quality level, the first lifespan factor of the vehicle's air conditioning system can be determined to be Y1 = 3.

[0038] Step 112: Determine the second life factor of the vehicle air conditioner based on the air quality level inside the vehicle's cabin.

[0039] The system uses a PM2.5 sensor inside the vehicle cabin to collect PM2.5 levels and determine the corresponding air quality level. It's important to note that the air quality level inside the cabin is positively correlated with the second lifespan factor; in other words, the better the air quality, the higher the second lifespan factor. For example, air quality levels are categorized as excellent, lightly polluted, moderate, and heavily polluted. Based on an excellent air quality level, the second lifespan factor Y2 for the vehicle's air conditioning system is determined to be 1. Based on a lightly polluted air quality level, the second lifespan factor Y2 is determined to be 2. Based on a heavily polluted air quality level, the second lifespan factor Y2 is determined to be 3.

[0040] Step 113: Select the larger value from the first lifespan factor and the second lifespan factor as the air quality lifespan factor of the vehicle air conditioner. That is, the air quality lifespan factor Y = max{Y1,Y2}. For example, if the first lifespan factor is 2 and the second lifespan factor is 3, the air quality lifespan factor Y is the larger value of 3.

[0041] Step 114: Determine multiple lifespan coefficients for the filter element based on the various circulation modes of the vehicle's air conditioning system. For example, the filter element's lifespan coefficient K1 can be determined based on the vehicle's internal circulation mode, the filter element's lifespan coefficient K2 can be determined based on the vehicle's external circulation mode, and the filter element's lifespan coefficient K3 can be determined based on the vehicle's internal and external circulation modes.

[0042] Based on the above steps, step 115 can be executed to obtain multiple lifetime factors.

[0043] Step 115: Calculate multiple lifespan factors of the filter element under various circulation modes based on the air quality lifespan factor and multiple lifespan coefficients. The lifespan factor under any given circulation mode can be calculated as: S = K × Y.

[0044] Continuing with the previous example, the filter element's lifespan factor S in recirculation mode can be calculated based on the air quality lifespan factor Y. 内 Let K1×Y be the filter element's lifespan factor S in external circulation mode. 外 The lifespan factor S of K2×Y and the filter element in external circulation mode. 内外 Let K3×Y be the value.

[0045] Alternatively, the lifespan of the air conditioning filter may be reduced due to driver habits (smoking or frequent switching of recirculation mode, etc.) and vehicle driving scenarios (industrial heavily polluted areas, etc.). Therefore, the multiple lifespan factors obtained through the above steps can be further trained by the cloud server according to the vehicle usage scenario and driver habits to make the multiple lifespan factors more accurate, thereby improving the accuracy of calculating the lifespan of the air conditioning filter.

[0046] In some optional embodiments, the remaining lifespan of the air conditioning filter is calculated based on a first duration, the second duration, a lifespan factor, and the total lifespan of the filter element. This can be achieved using the following steps, which will be explained in detail below with reference to Formulas 1 and 2.

[0047] Percentage of remaining lifespan = 1 – ((T1*S) 内 +T1*S 外 +T1*S 内外 )+(T2*S 内 +T2*S 外 +T2*S 内外 )) / T

[0048] (Formula 1)

[0049] By rearranging Formula 1, we can obtain Formula 2.

[0050] Percentage of remaining lifespan = 1 – (T1*(S) 内 +S 外 +S 内外 )+T2*(S 内 +S 外 +S 内外 )) / T

[0051] (Formula 2)

[0052] Where T1 is the first duration, T2 is the second duration, and S... 内 S is the lifespan factor in the internal circulation mode. 外 S is the lifetime factor in external circulation mode. 内外 This refers to the lifespan factor under both internal and external circulation modes.

[0053] First, the sum of multiple lifetime factors is used as the summation coefficient, i.e., S in Formula 2. 内 +S 外 +S 内外 The first and second durations are summed to obtain the filter cartridge usage time calculation result, i.e., T1*(S) in Formula 2. 内 +S 外 +S 内外 )+T2*(S 内 +S 外 +S 内外 ).

[0054] After obtaining the usage time calculation result, the ratio of the usage time calculation result to the total lifespan can be calculated as the filter element's lifespan consumption ratio, i.e., (T1*(S)) in Formula 2. 内 +S 外 +S 内外 )+T2*(S 内+S 外 +S 内外 )) / T.

[0055] Based on the above steps, the percentage of remaining lifespan of the air conditioning filter can be calculated according to the lifespan consumption ratio.

[0056] In some optional embodiments, outputting corresponding filter maintenance reminders based on the remaining lifespan of the air conditioner filter can be achieved through the following steps:

[0057] If the remaining lifespan of the air conditioner filter is less than a first threshold, a message prompting to clean the filter is output. If the remaining lifespan of the air conditioner filter is less than a second threshold, a message prompting to replace the filter is output. The second threshold is less than the first threshold. The first threshold can be preset according to actual design requirements, such as 65%, 30%, or 72%, etc., and this embodiment does not impose any restrictions. The second threshold can also be preset according to actual design requirements, such as 8%, 13%, or 15%, etc., and this embodiment does not impose any restrictions. The prompt message can be a voice message, a vibration prompt, or a text message, etc., and this embodiment does not impose any restrictions. For example, if the remaining lifespan of the air conditioner filter is 84%, which is less than the first threshold of 85%, a voice message saying "Please clean the filter in time" is output. If the remaining lifespan of the air conditioner filter is 15%, which is less than the second threshold of 20%, a voice message saying "Please replace the filter in time" is output.

[0058] This implementation method can promptly remind users to maintain the filter element based on its remaining lifespan, preventing passenger health and safety from being affected by a decline in filter performance.

[0059] Due to the inherent characteristics of the filter element, each cleaning reduces its lifespan. Therefore, cleaning too many times within a set cycle can lead to a short lifespan for the filter element, requiring timely replacement.

[0060] Based on this, in some optional embodiments, after outputting the filter element cleaning prompt message, the number of times the filter element is cleaned can be recorded. If the number of times the filter element is cleaned within a set period exceeds a set threshold, a filter element replacement prompt message is output. The set period can be half a month, one month, three months, or half a year, etc., and this embodiment does not impose any restrictions. The set threshold can be set according to actual design requirements, such as 3, 4, etc., and this embodiment does not impose any restrictions. For example, if the set threshold is 3, and the filter element is cleaned 4 times within half a year, a filter element replacement prompt message is output.

[0061] In some alternative embodiments, after each cleaning, the total lifespan of the filter element can be updated to a specified percentage of its pre-cleaning lifespan. This specified percentage can be 75%, 80%, or 85%, etc. For example, if the total lifespan of the filter element is 600 hours, after the first cleaning, the total lifespan is 80% of its pre-cleaning lifespan, i.e., 600 hours * 80% = 480 hours. After the second cleaning, the total lifespan is 80% of its pre-cleaning lifespan, i.e., 480 hours * 80% = 384 hours. After each cleaning, the updated total lifespan can be used in the calculations of the aforementioned embodiments (e.g., Formula 2), which will not be elaborated further.

[0062] In some optional embodiments, after replacing the filter element, the user can reset the filter element's lifespan. The ECU can respond to the filter element lifespan reset operation, obtain the usage time of the new filter element and use it as the new filter element's total lifespan, so as to perform lifespan detection on the new filter element based on the new filter element's total lifespan. The reset operation can include, but is not limited to, the following two implementations.

[0063] Implementation Method 1: When a diagnostic device is installed on the vehicle, a diagnostic command can be sent through the diagnostic device to reset the life of the filter element.

[0064] Implementation Method 2: In the absence of diagnostic equipment installed in the vehicle, the filter's lifespan can be reset using preset reset rules (such as key combination rules or air conditioning parameter setting rules). For example, pressing the recirculation button three times within 10 seconds will reset the filter's lifespan. Alternatively, setting the air conditioning temperature to 22°C, fan speed to level 1, recirculation mode to recirculation mode, and air conditioning mode to face / feet, then turning off the air conditioning will reset the filter's lifespan.

[0065] Through the above implementation method, after the vehicle's air conditioning filter is replaced, the ECU can reset the filter's lifespan through preset reset rules and diagnostic equipment, eliminating the need for vehicle maintenance personnel to reset the air conditioning filter's lifespan, saving labor costs, and avoiding false filter replacement prompts after filter replacement.

[0066] It should be noted that the execution subject of each step of the method provided in the above embodiments can be the same device, or the method can be executed by different devices. For example, the execution subject of steps 11 to 14 can be device A; or the execution subject of steps 11 and 12 can be device A, and the execution subject of steps 13 and 14 can be device B; and so on.

[0067] Furthermore, some processes described in the above embodiments and accompanying drawings include multiple operations that appear in a specific order. However, it should be clearly understood that these operations may not be executed in the order they appear herein, or they may be executed in parallel. The operation numbers, such as 11, 12, etc., are merely used to distinguish different operations and do not represent any execution order. In addition, these processes may include more or fewer operations, and these operations may be executed sequentially or in parallel.

[0068] It should be noted that the terms "first" and "second" in this article are used to distinguish different messages, devices, modules, etc., and do not represent a chronological order, nor do they limit "first" and "second" to different types.

[0069] This application provides a life testing device for vehicle air conditioning filters, such as... Figure 2 As shown, the life detection device for the vehicle air conditioning filter includes: a life factor determination module 201, a duration acquisition module 202, a life calculation module 203, and an information output module 204.

The duration acquisition module 202 is used to acquire a first duration when the airflow of the air conditioner is less than or equal to a specified level and a second duration when the airflow is greater than the specified level. The lifespan calculation module 203 is used to calculate the remaining lifespan of the air conditioner filter based on the first duration, the second duration, the lifespan factor, and the total lifespan of the air conditioner filter. The information output module 204 is used to output corresponding filter maintenance reminder information based on the remaining lifespan of the air conditioner filter.

[0071] Optionally, when determining the lifespan factor of the air conditioner filter element based on the air quality of the vehicle's driving environment and the circulation mode of the vehicle's air conditioner, the lifespan factor determination module 201 is specifically used for: determining a first lifespan factor of the vehicle's air conditioner based on the air quality level of the area where the vehicle is driving; determining a second lifespan factor of the vehicle's air conditioner based on the air quality level inside the vehicle's cabin; selecting the larger value from the first lifespan factor and the second lifespan factor as the air quality lifespan factor of the vehicle's air conditioner; determining multiple lifespan coefficients of the filter element based on multiple circulation modes of the vehicle's air conditioner; and calculating multiple lifespan factors of the filter element under multiple circulation modes based on the air quality lifespan factor and the multiple lifespan coefficients.

[0073] Further optionally, when the information output module 204 outputs corresponding filter maintenance reminder information based on the remaining lifespan of the air conditioner's filter, it is specifically used to: if the remaining lifespan of the air conditioner's filter is less than a first threshold, output a reminder message to clean the filter; if the remaining lifespan of the air conditioner's filter is less than a second threshold, output a reminder message to replace the filter; the second threshold is less than the first threshold.

[0074] Further optionally, after outputting a prompt message to clean the filter element, the information output module 204 is also used to: record the number of times the filter element is cleaned, and output a prompt message to replace the filter element when the number of times the filter element is cleaned within a set period is greater than a set number threshold; and / or, after each cleaning of the filter element, update the total lifespan of the filter element to a specified percentage of the total lifespan before cleaning.

[0075] Optionally, after outputting the prompt message to replace the filter element, the information output module 204 is further configured to: after replacing the new filter element, respond to the filter element life reset operation, obtain the usage time of the new filter element as the total life of the new filter element, and perform life detection on the new filter element based on the total life of the new filter element.

[0076] In this embodiment, the lifespan factor of the air conditioning filter can be determined based on the air quality of the vehicle's driving environment and the circulation mode of the vehicle's air conditioning system. Based on the duration of time the air conditioning fan speed is less than or equal to a specified setting, the duration of time the fan speed is greater than a specified setting, the lifespan factor, and the total lifespan of the air conditioning filter, the remaining lifespan of the air conditioning filter is calculated. Based on the remaining lifespan of the air conditioning filter, corresponding filter maintenance reminders are output. This implementation method allows for the calculation of the remaining lifespan of the vehicle's air conditioning filter, eliminating the need for vehicle maintenance personnel to assess the filter's lifespan, thus saving labor costs. Furthermore, it can remind passengers to maintain the filter in a timely manner based on the remaining lifespan, preventing harm to passengers' health due to decreased filter performance.

[0077] Figure 3 This is a schematic diagram of the structure of an electronic device provided in an exemplary embodiment of this application, such as... Figure 3 As shown, the electronic device includes a memory 301 and a processor 302.

[0078] Memory 301 is used to store computer programs and can be configured to store various other data to support operation on the terminal device. Examples of this data include instructions for any application or method used to operate on the terminal device, contact data, phone book data, messages, pictures, videos, etc.

[0079] The memory 301 can be implemented by any type of volatile or non-volatile storage device or a combination thereof, such as static random access memory (SRAM), electrically erasable programmable read-only memory (EEPROM), erasable programmable read-only memory (EPROM), programmable read-only memory (PROM), read-only memory (ROM), magnetic storage, flash memory, magnetic disk or optical disk.

[0080] The processor 302, coupled to the memory 301, is used to execute the computer program in the memory 301 to: determine the life factor of the air conditioner filter based on the air quality of the vehicle's driving environment and the circulation mode of the vehicle's air conditioner; obtain a first duration when the airflow of the air conditioner is less than or equal to a specified level and a second duration when the airflow is greater than the specified level; calculate the remaining life of the air conditioner filter based on the first duration, the second duration, the life factor, and the total lifespan of the air conditioner filter; and output corresponding filter maintenance reminder information based on the remaining lifespan of the air conditioner filter.
