Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and more specifically, to an air conditioner reminder method and a vehicle in the field of vehicle technology. Background Art

[0002] The air conditioning filter is the first line of defense for filtering air impurities in the car air conditioning system. If it is not replaced in time, it will easily cause the air conditioning filter to become seriously dirty. What's worse, the air conditioning filter will become moldy and cause certain harm to the human body. Therefore, it is particularly important to improve the accuracy of determining the replacement time of the air conditioning filter.

[0003] At present, whether to remind the user to replace the air conditioning filter is determined based on the accumulated mileage and accumulated time since the vehicle last replaced the air conditioning filter. However, since the time when the vehicle last replaced the air conditioning filter is only updated when the user replaces the air conditioning filter through an officially authorized vehicle repair shop, that is, when the user replaces the air conditioning filter through an unofficial authorized vehicle repair shop, the time will not be updated. Therefore, it is easy for the accumulated mileage and accumulated time after the vehicle last replaced the air conditioning filter to deviate greatly from the actual accumulated mileage and accumulated time after the vehicle last replaced the air conditioning filter, resulting in inaccurate determination of the timing to remind the user to replace the air conditioning filter. Summary of the invention

[0004] The present application provides an air conditioning reminder method and a vehicle, which can improve the accuracy of reminding users of the timing of replacing air conditioning filters, thereby avoiding waste of resources when the air conditioning filters are replaced too early, and affecting the air quality in the vehicle when the air conditioning filters are replaced too late.

[0006] In the above technical solution, the target aging rate of the air conditioning filter can be determined by obtaining the operating status data of the vehicle air conditioner and the service cycle data of the air conditioning filter of the vehicle air conditioner, and when the target aging rate of the air conditioning filter is greater than the first aging threshold, a prompt message for replacing the air conditioning filter is output. Since the target aging rate of the air conditioning filter is jointly determined by the operating status data of the vehicle air conditioner and the service cycle data of the air conditioning filter, and the operating status data of the vehicle air conditioner is not affected by the official maintenance record, it can improve the accuracy of the target aging rate of the air conditioning filter determined when there is a large deviation between the obtained service cycle data of the air conditioning filter and the actual service cycle data, that is, it can improve the accuracy of the target aging rate of the air conditioning filter determined when the user replaces the air conditioning filter through an unofficial authorized vehicle repair shop, thereby improving the accuracy of the timing of reminding the user to replace the air conditioning filter, avoiding waste of resources when the air conditioning filter is replaced too early, and affecting the air quality in the car when the air conditioning filter is replaced too late.

[0007] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the operating status data of the vehicle air conditioner includes the health status data of the vehicle air conditioner and the working data of the vehicle air conditioner, and the service life data of the air conditioning filter element includes the service life of the air conditioning filter element and the mileage of the vehicle; according to the operating status data of the vehicle air conditioner and the service life data of the air conditioning filter element, determining the target aging rate of the air conditioning filter element, including: processing the health status data of the vehicle air conditioner and the working data of the vehicle air conditioner respectively to obtain a first aging rate and a second aging rate of the air conditioning filter element, the first aging rate is used to indicate the working status and health level of the air conditioning filter element in the current environment, and the second aging rate is used to indicate the degree of wear of the air conditioning filter element in the actual working process; processing the service life of the air conditioning filter element and the mileage of the vehicle respectively to obtain a third aging rate and a fourth aging rate of the air conditioning filter element, the third aging rate is used to indicate the influence of dirt accumulated during the use of the air conditioning filter element on the performance of the air conditioning filter element, and the fourth aging rate is used to indicate the influence of the vehicle's mileage on the performance of the air conditioning filter element; summing the first aging rate, the second aging rate, the third aging rate and the fourth aging rate to obtain the target aging rate.

[0008] In combination with the first aspect and the above implementation manner, in some possible implementation manners, the health status data of the vehicle air conditioner includes the current alarm state of the vehicle air conditioner and the air quality of the environment in which the vehicle air conditioner is located; processing the health status data of the vehicle air conditioner to obtain a first aging rate of the air conditioning filter element includes: comparing the air quality of the environment in which the vehicle air conditioner is located with a corresponding target air quality index to obtain a first comparison result, and determining a threshold value corresponding to the first comparison result as a fifth aging rate of the air conditioning filter element;

[0009] Compare the current alarm state of the vehicle air conditioner with the target state to obtain a second comparison result, determine the flag corresponding to the second comparison result as the state value of the air conditioning filter element, the target state includes a first state and a second state, the first state is used to indicate that there is an abnormality in the air conditioning filter element, and the second state is used to indicate that there is no abnormality in the air conditioning filter element; sum the fifth aging rate and the state value of the air conditioning filter element to obtain the first aging rate.

[0010] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the working data of the vehicle air conditioner includes the usage data of the vehicle air conditioner within a preset time period; the working data of the vehicle air conditioner is processed to obtain a second aging rate of the air conditioning filter, including: comparing the usage data of the vehicle air conditioner within the preset time period with the corresponding usage threshold to obtain a third comparison result, and determining the threshold corresponding to the third comparison result as the second aging rate, and the usage threshold is the usage data of the vehicle air conditioner within the previous preset time period.

[0011] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the usage data of the vehicle air conditioner includes the startup duration, startup frequency and average set temperature of the vehicle air conditioner; the usage data of the vehicle air conditioner within a preset duration is compared with the corresponding usage threshold to obtain a third comparison result, and the threshold corresponding to the third comparison result is determined as the second aging rate, including: the startup duration, startup frequency and average set temperature of the vehicle air conditioner within the preset duration are compared with the corresponding target threshold to obtain a fourth comparison result, and the threshold corresponding to the fourth comparison result is determined as the second aging rate, and the corresponding target threshold is the startup duration, startup frequency and average set temperature of the vehicle air conditioner within the previous preset duration.

[0012] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the usage time of the air-conditioning filter is the cumulative time after the vehicle last replaced the air-conditioning filter or the cumulative time of using the air-conditioning filter after the vehicle last replaced the air-conditioning filter; the usage time of the air-conditioning filter is processed to obtain a third aging rate of the air-conditioning filter, including: comparing the cumulative time after the vehicle last replaced the air-conditioning filter with the corresponding first time threshold, obtaining a fifth comparison result, and determining the threshold corresponding to the fifth comparison result as the third aging rate; or, comparing the cumulative time of using the air-conditioning filter after the vehicle last replaced the air-conditioning filter with the corresponding second time threshold, obtaining a sixth comparison result, and determining the threshold corresponding to the sixth comparison result as the third aging rate.

[0013] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the vehicle's mileage is the cumulative mileage after the vehicle last replaced the air-conditioning filter or the cumulative mileage when the vehicle used the air-conditioning filter after the last replacement of the air-conditioning filter; the vehicle's mileage is processed to obtain a fourth aging rate of the air-conditioning filter, including: calculating the ratio between the cumulative mileage of the vehicle after the last replacement of the air-conditioning filter and the first benchmark mileage, obtaining the first ratio, determining the first ratio as the fourth aging rate, and the first benchmark mileage is the maximum mileage allowed for the vehicle after each replacement of the air-conditioning filter; or, calculating the ratio between the cumulative mileage of the vehicle when the air-conditioning filter was used after the last replacement of the air-conditioning filter and the second benchmark mileage, obtaining the second ratio, determining the second ratio as the fourth aging rate, and the second benchmark mileage is the maximum mileage allowed for the vehicle after each replacement of the air-conditioning filter.

[0014] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the first aging rate, the second aging rate, the third aging rate and the fourth aging rate are summed to obtain a target aging rate, including: summing the third aging rate and the fourth aging rate to obtain a sixth aging rate of the air-conditioning filter element, the sixth aging rate being used to indicate the impact of the usage cycle data of the air-conditioning filter element on the performance of the air-conditioning filter element; multiplying the first aging rate, the second aging rate and the sixth aging rate by their respective corresponding preset weights to obtain adjusted first aging rate, second aging rate and sixth aging rate; summing the adjusted first aging rate, second aging rate and sixth aging rate to obtain the target aging rate.

[0015] In the above technical scheme, after obtaining the sixth aging rate used to represent the influence of the vehicle's mileage and the usage time of the air-conditioning filter on the performance of the air-conditioning filter, taking into account that the first aging rate, the second aging rate and the sixth aging rate have different influences on the performance of the air-conditioning filter, that is, according to the influence on the performance of the air-conditioning filter, corresponding weights can be set for the first aging rate, the second aging rate and the sixth aging rate, respectively, and the target aging rate is determined in combination with the weights, that is, the first aging rate, the second aging rate and the sixth aging rate are multiplied by their respective corresponding preset weights to obtain the adjusted first aging rate, the second aging rate and the sixth aging rate, and the adjusted first aging rate, the second aging rate and the sixth aging rate are summed to obtain the target aging rate, thereby ensuring the accuracy of the determined target aging rate.

[0016] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, when the target aging rate of the air-conditioning filter is greater than the first aging threshold, a prompt message for replacing the air-conditioning filter is output, including: when the status value of the air-conditioning filter is the second flag bit and the target aging rate of the air-conditioning filter is greater than the second aging threshold, the prompt message for replacing the air-conditioning filter is not output, the second aging threshold is greater than the first aging threshold, and the second flag bit is used to indicate that there is no abnormality in the air-conditioning filter; when the status value of the air-conditioning filter is the first flag bit and the target aging rate of the air-conditioning filter is greater than the first aging threshold, a prompt message for replacing the air-conditioning filter is output, and the first flag bit is used to indicate that there is an abnormality in the air-conditioning filter.

[0017] In the above technical scheme, when the status value of the air-conditioning filter is the second flag bit, that is, there is no abnormality in the air-conditioning filter, and the target aging rate of the air-conditioning filter is greater than the second aging threshold, the prompt information for replacing the air-conditioning filter may not be output. Since there is no abnormality in the air-conditioning filter, it indicates that the air-conditioning filter has just been replaced. At this time, the target aging rate determined cannot reflect the performance of the air-conditioning filter in time. Therefore, in this case, the prompt information for replacing the air-conditioning filter may not be output, so as to avoid the air-conditioning filter being replaced too early and causing a waste of resources; when the status value of the air-conditioning filter is the first flag bit, that is, there is an abnormality in the air-conditioning filter, and the target aging rate of the air-conditioning filter is greater than the first aging threshold, it indicates that the air-conditioning filter has not been replaced, and the performance of the air-conditioning filter is very poor at this time, that is, in this case, it is necessary to output the prompt information for replacing the air-conditioning filter to remind the user to replace the air-conditioning filter, so as to avoid the air quality in the car being affected by the late replacement of the air-conditioning filter.

[0018] In a second aspect, a reminder device for an air conditioner is provided, the device comprising:

[0019] An acquisition module, used to acquire the operating status data of the vehicle air conditioner and the service life data of the air conditioning filter of the vehicle air conditioner;

[0021] The output module is used to output a prompt message for replacing the air conditioning filter element when the target aging rate of the air conditioning filter element is greater than a first aging threshold.

[0022] In a third aspect, a vehicle is provided, comprising a memory and a processor. The memory is used to store executable program code, and the processor is used to call and run the executable program code from the memory, so that the vehicle executes the air conditioning reminder method in the first aspect or any possible implementation of the first aspect.

[0029] The technical solution in the present application will be described clearly and in detail below in conjunction with the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0030] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0031] The air conditioning filter is the first line of defense for filtering air impurities in the car air conditioning system. If it is not replaced in time, it will easily cause the air conditioning filter to become seriously dirty. What's worse, the air conditioning filter will become moldy and cause certain harm to the human body. Therefore, it is particularly important to improve the accuracy of determining the replacement time of the air conditioning filter.

[0032] At present, whether it is necessary to remind the user to replace the air conditioning filter is determined based on the accumulated mileage and accumulated time since the vehicle last replaced the air conditioning filter. However, the time when the vehicle last replaced the air conditioning filter will only be updated when the user replaced the air conditioning filter through an officially authorized vehicle repair shop. That is, when the user replaces the air conditioning filter through an unofficial authorized vehicle repair shop, the time will not be updated. Therefore, it is easy for the accumulated mileage and accumulated time after the vehicle last replaced the air conditioning filter to deviate greatly from the actual accumulated mileage and accumulated time after the vehicle last replaced the air conditioning filter, resulting in inaccurate determination of the timing to remind the user to replace the air conditioning filter.

[0033] Based on the above problems, the present application provides an air conditioning reminder method, which can improve the accuracy of reminding users to replace the air conditioning filter, thereby avoiding waste of resources when the air conditioning filter is replaced too early, and affecting the air quality in the car when the air conditioning filter is replaced too late.

[0034] Figure 1 It is a schematic diagram of the implementation environment of an air conditioner reminder method provided in an embodiment of the present application.

[0035] For example, Figure 1 As shown, the implementation environment includes a vehicle control unit (VCU) 101 and an air conditioning management system 102 .

[0036] The vehicle controller 101 is an important control unit of the vehicle, which can obtain relevant data of the vehicle and control the vehicle to perform corresponding operations based on the relevant data. For example, the vehicle controller can obtain the operating status data of the vehicle air conditioner and the service life data of the air conditioning filter of the vehicle air conditioner, and based on the data, determine whether to output the prompt information of replacing the air conditioning filter.

[0037] In some embodiments, the vehicle controller 101 can receive the operating status data of the vehicle air conditioner and the usage cycle data of the air-conditioning filter of the vehicle air conditioner collected by the air-conditioning management system 102, and determine the health status of the air-conditioning filter based on the data, that is, the target aging rate of the air-conditioning filter, and then determine whether to output a prompt message for replacing the air-conditioning filter based on the target aging rate.

[0038] Below through Figure 2 The method of the embodiment of the present application is described in detail.

[0039] Figure 2 It is a schematic flow chart of an air conditioner reminder method provided in an embodiment of the present application.

[0040] For example, Figure 2 As shown, taking the execution subject as a vehicle controller as an example, the method 200 includes the following steps 201 to 203:

[0041] Step 201, obtaining the operating status data of the vehicle air conditioner and the service life data of the air conditioning filter of the vehicle air conditioner.

[0042] In a possible implementation, the vehicle controller may obtain the operating status data of the vehicle air conditioner and the service life data of the air conditioning filter of the vehicle air conditioner from the air conditioning management system via a controller area network (CAN) bus.

[0043] Step 202 , determining a target aging rate of the air conditioning filter element according to the operating status data of the vehicle air conditioning and the service life data of the air conditioning filter element.

[0044] Specifically, after obtaining the operating status data of the vehicle air conditioner and the service cycle data of the air-conditioning filter of the vehicle air conditioner, the vehicle controller can determine the health status of the air-conditioning filter, that is, the target aging rate of the air-conditioning filter, based on the operating status data of the vehicle air conditioner and the service cycle data of the air-conditioning filter of the vehicle air conditioner, so as to subsequently determine whether it is necessary to output a prompt message for replacing the air-conditioning filter based on the target aging rate.

[0045] In a possible implementation, the operating status data of the vehicle air conditioner includes health status data and working data of the vehicle air conditioner, and the service life data of the air conditioning filter includes the service time of the air conditioning filter and the mileage of the vehicle.

[0046] The following is divided into three parts, which introduce in detail the implementation method of determining the target aging rate of the air conditioning filter element in step 202.

[0047] In the first part, the health status data and the working data of the vehicle air conditioner are processed respectively to obtain the first aging rate and the second aging rate of the air conditioning filter. The first aging rate is used to indicate the working status and health level of the air conditioning filter in the current environment, and the second aging rate is used to indicate the degree of wear of the air conditioning filter during actual working.

[0048] The specific implementation method for obtaining the first aging rate of the air-conditioning filter element is first described in detail below.

[0049] Among them, the health status data of the vehicle air conditioner may include the current alarm status of the vehicle air conditioner and the air quality of the environment in which the vehicle air conditioner is located. Correspondingly, in a possible implementation manner, the health status data of the vehicle air conditioner is processed to obtain a first aging rate of the air conditioning filter element, including: comparing the air quality of the environment in which the vehicle air conditioner is located with the corresponding target air quality index to obtain a first comparison result, and determining the threshold corresponding to the first comparison result as the fifth aging rate of the air conditioning filter element; comparing the current alarm status of the vehicle air conditioner with the target status to obtain a second comparison result, and determining the flag corresponding to the second comparison result as the status value of the air conditioning filter element, the target status includes a first status and a second status, the first status is used to indicate that there is an abnormality in the air conditioning filter element, and the second status is used to indicate that there is no abnormality in the air conditioning filter element; the fifth aging rate and the status value of the air conditioning filter element are summed to obtain the first aging rate.

[0050] Among them, the value range of the fifth aging rate is 0 to 1. The larger the fifth aging rate is, the worse the air quality of the environment in which the vehicle air conditioner is located is, and the lower the performance of the air conditioning filter is.

[0051] The following describes how to obtain the current alarm status of the vehicle air conditioner and the air quality of the environment in which the vehicle air conditioner is located.

[0052] In a possible implementation, the current alarm state of the vehicle air conditioner includes a first state and a second state, the first state is used to indicate that the air conditioner filter element is abnormal, and the second state is used to indicate that the air conditioner filter element is not abnormal. The abnormality of the air conditioner filter element can be understood as a blockage of the air conditioner filter element.

[0053] It should be noted that there is a fault detection module in the air conditioning management system, which can detect various abnormal conditions of the vehicle air conditioning, generate an alarm signal, and transmit the alarm signal to the vehicle controller through the controller area network (CAN) bus or other communication protocols. It should be noted that in order to enable the vehicle controller to determine the fault type of the vehicle air conditioning according to the alarm signal, thereby determining the current alarm state (first state / second state) of the vehicle air conditioning, that is, to determine whether the air conditioning filter element is currently abnormal, in a possible implementation, the alarm signal can indicate a specific fault type (for example, the alarm signal can indicate that the air conditioning filter element is clogged, the temperature sensor is faulty, or the fan is faulty, etc.), so that the vehicle controller can determine the current alarm state of the vehicle air conditioning according to the alarm signal.

[0054] It is understandable that the air quality of the environment in which the vehicle air conditioner is located, that is, the air quality inside the vehicle is determined by the concentration of particulate matter (PM2.5) with a diameter less than or equal to 2.5μm, carbon dioxide (CO2), and volatile organic compounds (VOCs). Specifically, when determining the air quality of the environment in which the vehicle air conditioner is located, the vehicle controller can first convert the concentrations of PM2.5, CO2, and VOCs into corresponding air quality indexes, and then determine the air quality based on the highest air quality index. That is, in an embodiment of the present application, it is necessary to first obtain the concentrations of PM2.5, CO2, and VOCs inside the vehicle, and use the corresponding conversion table to convert them into air quality indexes, and finally determine the highest air quality index as the air quality of the environment in which the vehicle air conditioner is located.

[0055] In a possible implementation, the vehicle controller may obtain the PM2.5 concentration inside the vehicle through a PM2.5 monitor, obtain the CO2 concentration inside the vehicle through a CO2 monitor, and obtain the VOCs concentration inside the vehicle through a VOCs monitor.

[0056] Among them, the concentration conversion table of PM2.5, CO2 and VOCs is set in advance by the developers according to national standards and stored in the vehicle's internal memory.

[0057] For example, the conversion table between PM2.5 concentration and the corresponding air quality index is shown in Table 1 below:

[0058] Table 1

[0059] <![CDATA[PM2.5(μg / m 3 )]]> Air Quality Index 0～35 35 35～75 80 75～115 120 115～150 180 …… ……

[0060] For example, the conversion table between CO2 concentration and the corresponding air quality index is shown in Table 2 below:

[0061] Table 2

[0062]

[0063]

[0064] For example, the conversion table between VOCs concentration and the corresponding air quality index is shown in Table 3 below:

[0065] Table 3

[0066] <![CDATA[VOCs(mg / m 3 )]]> Air Quality Index 0～0.3 35 0.3～0.6 80 0.6～1.0 120 1.0～2.0 180 …… ……

[0067] For example, when the PM2.5 concentration is 120 μg / m 3 , CO2 concentration is 440ppm, VOCs concentration is 0.2mg / m 3When the PM2.5 concentration is 120 μg / m 3 The corresponding air quality index is 180, the corresponding air quality index for CO2 concentration is 440ppm, and the corresponding air quality index for VOCs concentration is 0.2mg / m 3 The corresponding air quality index is 35, and the highest air quality index will be 120μg / m 3 The corresponding air quality index (180) is determined as the air quality of the environment in which the vehicle air conditioner is located.

[0068] After obtaining the current alarm status of the vehicle air conditioner and the air quality of the environment in which the vehicle air conditioner is located, the process of determining the fifth aging rate of the air conditioning filter element is described in detail.

[0069] It should be noted that the air quality of the environment in which the vehicle air conditioner is located, that is, the concentration of PM2.5, CO2 and VOCs in the environment in which the vehicle air conditioner is located, can reflect the performance of the air conditioning filter element, that is, the higher the air quality of the environment in which the vehicle air conditioner is located, the higher the performance of the air conditioning filter element; the lower the air quality of the environment in which the vehicle air conditioner is located, the lower the performance of the air conditioning filter element. That is, in a possible implementation manner, the air quality of the environment in which the vehicle air conditioner is located can be compared with the first air quality index and the second air quality index respectively. When the air quality is less than or equal to the first air quality index, the first threshold is determined as the fifth aging rate; when the air quality is greater than the first air quality index and less than the second air quality index, the second threshold is determined as the fifth aging rate, and the second threshold is greater than the first threshold; when the air quality is greater than the second air quality index, the third threshold is determined as the fifth aging rate, and the third threshold is greater than the second threshold.

[0070] Among them, the first air quality index and the second air quality index are set in advance by the developer based on experimental data and stored in the vehicle's internal memory. For example, the first air quality index is 50 and the second air quality index is 150. The embodiment of the present application does not limit the number and size of the set air quality indicators.

[0071] It should be noted that when the air quality is less than or equal to the first air quality index, it indicates that the air quality of the environment in which the vehicle air conditioner is located is good, that is, the performance of the air conditioning filter is good at this time, that is, in this case, the first threshold can be determined as the second aging rate. Among them, the first threshold is the minimum value of the fifth aging rate. Exemplarily, when the minimum value of the fifth aging rate is 0, the first threshold is also 0, in which case the first threshold (0) will be determined as the fifth aging rate.

[0072] When the air quality is greater than the first air quality index and less than the second air quality index, it indicates that the air quality of the environment in which the vehicle air conditioner is located is poor, that is, the performance of the air conditioning filter is poor at this time, that is, in this case, the second threshold value greater than the first threshold value can be determined as the fifth aging rate to increase the fifth aging rate of the air conditioning filter element. Exemplarily, when the second threshold value greater than the first threshold value is 0.4, in this case, the second threshold value (0.4) will be determined as the fifth aging rate to increase the second aging rate of the air conditioning filter element.

[0073] When the air quality is greater than the second air quality index, it indicates that the air quality of the environment in which the vehicle air conditioner is located is very poor, that is, the performance of the air conditioning filter is very poor at this time, that is, in this case, the sixth third threshold value greater than the second threshold value can be determined as the fifth aging rate to further increase the fifth aging rate of the air conditioning filter element, thereby ensuring the accuracy of the determined target aging rate. Exemplarily, when the third threshold value greater than the second threshold value is 1, in this case, the third threshold value (1) will be determined as the fifth aging rate to further increase the fifth aging rate of the air conditioning filter element, thereby ensuring the accuracy of the determined target aging rate.

[0074] In order to improve the accuracy of the fifth aging rate of the determined air conditioning filter, in a possible implementation, when the air quality is greater than the first air quality index and less than the second air quality index, it can also be determined whether the air quality is greater than the third air quality index and less than the fourth air quality index, so that when the air quality is greater than the third air quality index and less than the fourth air quality index, the fourth threshold value greater than the second threshold value and less than the third threshold value is determined as the second aging rate. Exemplarily, when the second threshold value is 0.4 and the third threshold value is 1, the fourth threshold value can be 0.8, that is, in this case, the fourth threshold value (0.8) will be determined as the fifth aging rate.

[0075] After introducing the process of determining the fifth aging rate of the air conditioning filter, the process of determining the status value of the air conditioning filter is introduced in detail.

[0076] It can be seen from the above embodiments that the current alarm state of the vehicle air conditioner includes a first state for indicating that there is an abnormality in the air conditioning filter element and a second state for indicating that there is no abnormality in the air conditioning filter element. That is, in a possible implementation, the current alarm state of the vehicle air conditioner can be compared with the first state and the second state, so that when the current alarm state of the vehicle air conditioner is the first state, that is, when there is an abnormality in the air conditioning filter element, the first flag bit is determined as the state value of the air conditioning filter element; when the current alarm state of the vehicle air conditioner is the second state, that is, when there is no abnormality in the air conditioning filter element, the second flag bit is determined as the state value of the air conditioning filter element.

[0077] Exemplarily, the first flag bit is 0, and the second flag bit is 1. When there is an abnormality in the air-conditioning filter, the first flag bit (0) is determined as the status value of the air-conditioning filter; when there is no abnormality in the air-conditioning filter, the second flag bit (1) is determined as the status value of the air-conditioning filter.

[0078] After obtaining the fifth aging rate of the air conditioning filter element and the status value of the air conditioning filter element, the process of determining the first aging rate is then described in detail.

[0079] In a possible implementation manner, after the fifth aging rate of the air conditioning filter element and the state value of the air conditioning filter element are obtained, the fifth aging rate and the state value of the air conditioning filter element may be summed to obtain the first aging rate.

[0080] Exemplarily, when the fifth aging rate is 0.4 and the state value of the air conditioning filter is 0, the fifth aging rate (0.4) and the state value of the air conditioning filter (0) may be summed to obtain the first aging rate = 0.4 + 0 = 0.4.

[0081] In order to improve the accuracy of the determined first aging rate, in another possible implementation manner, corresponding weights can be set for the fifth aging rate of the air-conditioning filter and the status value of the air-conditioning filter, so that after obtaining the fifth aging rate of the air-conditioning filter and the status value of the air-conditioning filter, the fifth aging rate and the status value of the air-conditioning filter are multiplied by their respective corresponding weights to obtain the adjusted fifth aging rate and the adjusted status value of the air-conditioning filter, and the adjusted fifth aging rate and the adjusted status value of the air-conditioning filter are summed to obtain the first aging rate, thereby improving the accuracy of the determined first aging rate.

[0082] It should be noted that the performance of the air-conditioning filter element will directly affect the air quality of the environment in which the vehicle air-conditioning is located, that is, the air quality of the environment in which the vehicle air-conditioning is located can directly reflect the performance of the air-conditioning filter element, and the current alarm status of the vehicle air-conditioning is not a continuous indicator, that is, the current alarm status of the vehicle air-conditioning may only be the status of the air-conditioning filter element at a certain moment. Therefore, the current alarm status of the vehicle air-conditioning cannot directly reflect the performance of the air-conditioning filter element. In order to improve the accuracy of the determined first aging rate, in an embodiment of the present application, different weights can be assigned to the fifth aging rate determined based on the air quality of the environment in which the vehicle air-conditioning is located and the status value of the air-conditioning filter element determined based on the current alarm status of the vehicle air-conditioning (it should be understood that the weight set for the fifth aging rate should be greater than the weight set for the status value of the air-conditioning filter element).

[0083] After introducing the specific implementation method for obtaining the first aging rate of the air-conditioning filter element, the specific implementation method for obtaining the second aging rate of the air-conditioning filter element will be introduced in detail below.

[0084] Among them, the working data of the vehicle air conditioner may include the usage data of the vehicle air conditioner within a preset time period. Correspondingly, in a possible implementation manner, the working data of the vehicle air conditioner is processed to obtain the second aging rate of the air-conditioning filter element, including: comparing the usage data of the vehicle air conditioner within the preset time period with the corresponding usage threshold to obtain a third comparison result, and determining the threshold corresponding to the third comparison result as the second aging rate, and the usage threshold is the usage data of the vehicle air conditioner within the previous preset time period.

[0085] The preset duration is set by the developer based on experimental data or real vehicle simulation. For example, the preset duration may be 3 days, a week, or a month, etc., which is not limited in the present embodiment.

[0086] The value range of the second aging rate is 0 to 1. The larger the second aging rate is, the lower the performance of the air conditioning filter element is.

[0087] Specifically, after obtaining the usage data of the vehicle air conditioner within a preset time period, the usage data of the vehicle air conditioner within the preset time period can be compared with the corresponding usage threshold. When the usage data of the vehicle air conditioner is less than or greater than the corresponding usage threshold, the fifth threshold is determined as the second aging rate; when the usage data of the vehicle air conditioner is equal to the corresponding usage threshold, the sixth threshold is determined as the second aging rate, and the sixth threshold is less than the fifth threshold.

[0088] It should be noted that since the performance of the air-conditioning filter will affect the user's usage habits, that is, it will affect the usage data of the vehicle air conditioner, the acquired usage data of the vehicle air conditioner can be compared with the usage data of the vehicle air conditioner within the previous preset time period. When there is a deviation between the two, it indicates that the performance of the air-conditioning filter is significantly reduced, that is, in this case, the fifth threshold can be determined as the second aging rate. When there is no deviation between the two, it indicates that the performance of the air-conditioning filter has not declined significantly, that is, in this case, the sixth threshold that is less than the fifth threshold can be determined as the second aging rate.

[0089] In a possible implementation, the usage data of the vehicle air conditioner may include the startup duration, startup frequency and average set temperature of the vehicle air conditioner; the usage data of the vehicle air conditioner within a preset duration is compared with the corresponding usage threshold to obtain a third comparison result, and the threshold corresponding to the third comparison result is determined as the second aging rate, including: the startup duration, startup frequency and average set temperature of the vehicle air conditioner within the preset duration are compared with the corresponding target threshold to obtain a fourth comparison result, and the threshold corresponding to the fourth comparison result is determined as the second aging rate, and the corresponding target threshold is the startup duration, startup frequency and average set temperature of the vehicle air conditioner within the previous preset duration.

[0090] Among them, the corresponding target threshold is the startup duration, startup frequency and average set temperature of the vehicle air conditioner within the previous preset time period.

[0091] The following describes how to obtain the startup duration, startup frequency and average set temperature of the car air conditioner.

[0092] In one possible implementation, the vehicle controller can detect the status (on and off) of the vehicle air conditioner through an air-conditioning status sensor, record the duration and start-up time of each start-up of the vehicle air conditioner through a time sensor, detect the temperature set for each time of the vehicle air conditioner through a temperature sensor, and generate a log file with the above-mentioned collected data (i.e., the start-up time, start-up duration and set temperature of the vehicle air conditioner), and store the log file in the vehicle's internal memory or an external storage device, such as an SD card or a cloud server, so that the vehicle controller can extract the required data from the log file, i.e., the start-up time, start-up duration and set temperature of each start-up of the vehicle air conditioner. After extracting the start-up time, start-up duration and set temperature of each start-up of the vehicle air conditioner, the vehicle controller will accumulate the start-up time and start-up frequency of the vehicle air conditioner within the preset time, and calculate the average value of the temperature set when the vehicle air conditioner is started within the preset time.

[0093] After obtaining the startup duration, startup frequency and average set temperature of the vehicle air conditioner, the process of determining the second aging rate of the air conditioner filter is described in detail.

[0094] It should be noted that when the air conditioning filter is seriously aged, that is, the performance of the air conditioning filter is very low, the user will increase the duration and frequency of starting the vehicle air conditioning and change the set air conditioning temperature, so that the temperature inside the vehicle can meet their own needs. That is, in the embodiment of the present application, after obtaining the usage data of the vehicle air conditioning within the preset time, that is, the start-up time, start-up frequency and average set temperature of the vehicle air conditioning within the preset time, the start-up time, start-up rate and average set temperature of the vehicle air conditioning can be compared with the corresponding target thresholds, so that when the start-up time, start-up frequency and average set temperature of the vehicle air conditioning are all equal to the corresponding target thresholds, the seventh threshold is determined as the second aging rate; when any one of the start-up time, start-up frequency and average set temperature is less than or greater than the corresponding target threshold, the eighth threshold is determined as the second aging rate, and the eighth threshold is greater than the seventh threshold; when the start-up time, start-up frequency and average set temperature are all less than or greater than the corresponding target threshold, the ninth threshold is determined as the second aging rate, and the ninth threshold is greater than the eighth threshold.

[0095] It should be noted that when the startup duration, startup frequency and average set temperature are all equal to the corresponding target thresholds, it indicates that the user's usage pattern of the car air conditioner has not changed (it can be understood that the duration, frequency and average set temperature of the user starting the car air conditioner have not changed compared with the startup duration, startup frequency and average set temperature within the previous preset duration), that is, the performance of the air conditioning filter is better at this time, that is, in this case, the seventh threshold can be determined as the second aging rate. Among them, the seventh threshold is the minimum value of the second aging rate. Exemplarily, when the minimum value of the second aging rate is 0, the seventh threshold is also 0, in which case the seventh threshold (0) will be determined as the second aging rate.

[0096] When any one of the startup duration, startup frequency, and average set temperature is less than or greater than the corresponding target threshold, it indicates that the user's usage pattern of the vehicle air conditioner has slightly changed, that is, the performance of the air conditioning filter element has slightly decreased, and the performance of the air conditioning filter element is poor. In this case, the eighth threshold greater than the seventh threshold can be determined as the second aging rate to increase the first aging rate of the air conditioning filter element. Exemplarily, when the eighth threshold greater than the seventh threshold is 0.3, in this case, the eighth threshold (0.3) will be determined as the second aging rate to increase the second aging rate of the air conditioning filter element.

[0097] When the startup duration, startup frequency, and average set temperature are all less than or greater than the corresponding target threshold, it indicates that the user's usage pattern of the vehicle air conditioner has changed greatly, that is, the performance of the air conditioning filter element has significantly decreased, and the performance of the air conditioning filter element is very poor. In this case, the ninth threshold value greater than the eighth threshold value can be determined as the second aging rate to further increase the second aging rate of the air conditioning filter element, thereby ensuring the accuracy of the determined target aging rate. Exemplarily, when the ninth threshold value greater than the eighth threshold value is 1, in this case, the ninth threshold value (1) will be determined as the second aging rate to further increase the second aging rate of the air conditioning filter element, thereby ensuring the accuracy of the determined target aging rate.

[0098] In order to improve the accuracy of the second aging rate of the determined air conditioning filter, in a possible implementation, when any one of the startup duration, startup frequency and average set temperature is less than or greater than the corresponding target threshold, it can also be determined whether any two of the startup duration, startup frequency and average set temperature are less than or greater than the corresponding target threshold, so that when any two of the startup duration, startup frequency and average set temperature are less than or greater than the corresponding target threshold, the tenth threshold greater than the eighth threshold and less than the ninth threshold is determined as the second aging rate. Exemplarily, when the eighth threshold is 0.3 and the ninth threshold is 1, the tenth threshold can be 0.7, that is, in this case, the tenth threshold (0.7) will be determined as the second aging rate.

[0099] In the second part, the usage time of the air-conditioning filter and the mileage of the vehicle are processed respectively to obtain the third and fourth aging rates of the air-conditioning filter. The third aging rate is used to indicate the influence of the dirt accumulated during the use of the air-conditioning filter on the performance of the air-conditioning filter. The fourth aging rate is used to indicate the influence of the vehicle's mileage on the performance of the air-conditioning filter.

[0100] Among them, the value range of the third aging rate is 0 to 1. The larger the fourth aging rate is, the longer the air-conditioning filter is used, and the lower the performance of the air-conditioning filter is.

[0101] The value range of the fourth aging rate is 0 to 1. The larger the fourth aging rate is, the higher the mileage of the vehicle is, and the lower the performance of the air conditioning filter is.

[0102] The specific implementation method for obtaining the third aging rate of the air conditioning filter element is first described in detail below.

[0103] Among them, the usage time of the air-conditioning filter can be the cumulative time after the vehicle last replaced the air-conditioning filter or the cumulative time of using the air-conditioning filter after the vehicle last replaced the air-conditioning filter. Correspondingly, in a possible implementation mode, the usage time of the air-conditioning filter is processed to obtain the third aging rate of the air-conditioning filter, including: comparing the cumulative time after the vehicle last replaced the air-conditioning filter with the corresponding first time threshold to obtain a fifth comparison result, and determining the threshold corresponding to the fifth comparison result as the third aging rate; or, comparing the cumulative time after the vehicle last replaced the air-conditioning filter with the corresponding second time threshold to obtain a sixth comparison result, and determining the threshold corresponding to the sixth comparison result as the third aging rate.

[0104] The following describes how to obtain the cumulative length of time since the vehicle's last air conditioning filter replacement and the cumulative length of time the vehicle's air conditioning filter has been used since the vehicle's last air conditioning filter replacement.

[0105] In one possible implementation, the vehicle controller can access the vehicle's maintenance record through the database interface of an officially authorized vehicle repair shop, query the date when the vehicle's air conditioning filter was last replaced, and then calculate the cumulative time since the vehicle's last air conditioning filter was replaced based on the current date.

[0106] In one possible implementation, the vehicle controller can detect the status (on and off) of the vehicle air conditioner through an air-conditioning status sensor, record the duration and start-up time of each start-up of the vehicle air conditioner through a time sensor, and generate a log file for the startup duration and start-up time of the above-mentioned vehicle air conditioner, and store the log file in the vehicle's internal memory or an external storage device, such as an SD card or a cloud server, so that the vehicle controller can extract the required data from the log file, that is, the duration and start-up time of each start-up of the vehicle air conditioner, and according to the current date and the date of replacing the air-conditioning filter, accumulate the time of starting the vehicle air conditioner after the vehicle last replaced the air-conditioning filter, thereby obtaining the cumulative time of using the air-conditioning filter after the vehicle last replaced the air-conditioning filter.

[0107] After obtaining the cumulative time since the vehicle last replaced the air-conditioning filter and the cumulative time the air-conditioning filter was used since the vehicle last replaced the air-conditioning filter, the process of determining the third aging rate of the air-conditioning filter based on the cumulative time since the vehicle last replaced the air-conditioning filter is described in detail.

[0108] It should be noted that the longer the cumulative time since the vehicle last replaced the air conditioning filter, the more the performance of the air conditioning filter will decline, that is, the lower the performance of the air conditioning filter. In other words, the performance of the air conditioning filter will decrease as the cumulative time since the vehicle last replaced the air conditioning filter increases. That is, in a possible implementation, the cumulative time since the vehicle last replaced the air conditioning filter can be compared with the third time threshold and the fourth threshold, respectively, so that when the cumulative time is less than or equal to the third time threshold, the eleventh threshold is determined as the third aging rate; when the cumulative time is greater than the third time threshold and less than the fourth time threshold, the twelfth threshold is determined as the third aging rate, and the twelfth threshold is greater than the eleventh threshold; when the cumulative time is greater than the fourth time threshold, the thirteenth threshold is determined as the third aging rate, and the thirteenth threshold is greater than the twelfth threshold.

[0109] The third time threshold and the fourth time threshold are set in advance by the developer based on experimental data and stored in the vehicle's internal memory. For example, the third time threshold is 183 days (which can also be understood as half a year) and the fourth time threshold is 365 (which can also be understood as one year). The embodiment of the present application does not limit the number and size of the set time thresholds.

[0110] It should be noted that, when the cumulative time after the last replacement of the air conditioning filter of the vehicle is less than or equal to the third time threshold, it indicates that the air conditioning filter has been used for a short time, that is, the performance of the air conditioning filter is better at this time, and the eleventh threshold can be determined as the third aging rate. Among them, the eleventh threshold is the minimum value of the third aging rate. Exemplarily, when the minimum value of the third aging rate is 0, the eleventh threshold is also 0, in which case the eleventh threshold (0) will be determined as the third aging rate.

[0111] When the accumulated time after the last replacement of the air conditioning filter of the vehicle is greater than the third time threshold and less than the fourth time threshold, it indicates that the air conditioning filter has been used for a long time, and the performance of the air conditioning filter has slightly decreased, that is, the performance of the air conditioning filter is poor at this time, that is, in this case, the twelfth threshold greater than the eleventh threshold can be determined as the third aging rate to increase the third aging rate of the air conditioning filter. Exemplarily, when the twelfth threshold greater than the eleventh threshold is 0.5, in this case, the twelfth threshold (0.5) will be determined as the third aging rate to increase the third aging rate of the air conditioning filter.

[0112] When the accumulated time after the last replacement of the air conditioning filter of the vehicle is greater than the fourth time threshold, it indicates that the air conditioning filter has been used for a long time, and the performance of the air conditioning filter has significantly decreased. In this case, the thirteenth threshold greater than the twelfth threshold can be determined as the third aging rate to further increase the third aging rate of the air conditioning filter, thereby ensuring the accuracy of the determined target aging rate. Exemplarily, when the thirteenth threshold greater than the twelfth threshold is 1, in this case, the thirteenth threshold (1) will be determined as the third aging rate to further increase the third aging rate of the air conditioning filter, thereby ensuring the accuracy of the determined target aging rate.

[0113] After introducing the process of determining the third aging rate of the air-conditioning filter based on the cumulative time since the vehicle last replaced the air-conditioning filter, the following introduces the process of determining the third aging rate of the air-conditioning filter based on the cumulative time since the vehicle last replaced the air-conditioning filter.

[0114] Similarly, the longer the cumulative time of using the air conditioning filter after the vehicle last replaced the air conditioning filter, the more the performance of the air conditioning filter will decrease, that is, the lower the performance of the air conditioning filter. In other words, the performance of the air conditioning filter will decrease as the cumulative time of using the air conditioning filter after the vehicle last replaced the air conditioning filter increases, that is, in a possible implementation, the cumulative time of using the air conditioning filter after the vehicle last replaced the air conditioning filter can be compared with the fifth time threshold and the sixth time threshold, respectively, so that when the cumulative time of using the air conditioning filter is less than or equal to the fifth time threshold, the fourteenth threshold is determined as the third aging rate, and when the cumulative time is greater than the fifth time threshold and less than the sixth time threshold, the fifteenth threshold is determined as the third aging rate, and the fifteenth threshold is greater than the fourteenth threshold; when the cumulative time is greater than the sixth time threshold, the sixteenth threshold is determined as the third aging rate, and the sixteenth threshold is greater than the fifteenth threshold.

[0115] Among them, the fifth time threshold and the sixth time threshold are set in advance by the developer based on experimental data and stored in the vehicle's internal memory. It is understandable that the increase in the cumulative use time of the air conditioning filter after the vehicle last replaced the air conditioning filter will also increase the cumulative time after the vehicle last replaced the air conditioning filter, that is, the fifth time threshold and the sixth time threshold set by the developer can be the same as the third time threshold and the fourth time threshold, for example, the fifth time threshold can also be 183 days, the sixth time threshold can also be 365, etc., and the embodiments of the present application do not limit this.

[0116] It should be noted that the above-mentioned comparing the cumulative time of using the air-conditioning filter after the vehicle last replaced the air-conditioning filter with the fifth time threshold and the sixth time threshold respectively, so as to determine the corresponding threshold according to the comparison result, and determining the corresponding threshold as the implementation method and principle of the third aging rate is the same as the above-mentioned comparing the cumulative time after the vehicle last replaced the air-conditioning filter with the third time threshold and the fourth time threshold respectively, so as to determine the corresponding threshold according to the comparison result, and determining the corresponding threshold as the implementation method and principle of the third aging rate. Please refer to the above embodiment for details, which will not be repeated here.

[0117] After introducing the specific implementation method of obtaining the third aging rate of the air-conditioning filter element, the specific implementation method of obtaining the fourth aging rate of the air-conditioning filter element will be introduced in detail below.

[0118] Among them, the vehicle's mileage is the cumulative mileage after the vehicle last replaced the air-conditioning filter or the cumulative mileage when the vehicle used the air-conditioning filter after the last replacement of the air-conditioning filter. Correspondingly, in a possible implementation mode, the vehicle's mileage is processed to obtain a fourth aging rate of the air-conditioning filter, including: calculating the ratio between the cumulative mileage of the vehicle after the last replacement of the air-conditioning filter and the first benchmark mileage to obtain a first ratio, and determining the first ratio as the fourth aging rate, the first benchmark mileage being the maximum mileage allowed for the vehicle after each replacement of the air-conditioning filter; or calculating the ratio between the cumulative mileage when the vehicle used the air-conditioning filter after the last replacement of the air-conditioning filter and the second benchmark mileage to obtain a second ratio, and determining the second ratio as the fourth aging rate, the second benchmark mileage being the maximum mileage allowed for the vehicle after each replacement of the air-conditioning filter.

[0119] The following describes how to obtain the vehicle's cumulative mileage after the last air conditioning filter replacement and the vehicle's cumulative mileage while using the air conditioning filter after the last air conditioning filter replacement.

[0120] In one possible implementation, the vehicle controller can access the vehicle's maintenance record through the database interface of an officially authorized vehicle repair shop, query the mileage of the vehicle's last air-conditioning filter replacement, and then calculate the vehicle's cumulative mileage since the last air-conditioning filter replacement based on the current mileage.

[0121] In one possible implementation, the vehicle controller can extract the time of each start-up of the vehicle air conditioner and the corresponding mileage of the vehicle through a log file stored in the vehicle's internal memory or external storage device, so that after each start-up of the vehicle air conditioner, when the air-conditioning status sensor detects that the vehicle air conditioner is turned off, the increase in the vehicle's mileage during the vehicle air-conditioning start-up period can be recorded, and then based on the current date and the date of replacement of the air-conditioning filter, the increase in mileage each time the vehicle air conditioner is started after the last replacement of the air-conditioning filter is accumulated, thereby obtaining the cumulative mileage of the vehicle when using the air-conditioning filter after the last replacement of the air-conditioning filter.

[0122] After obtaining the cumulative mileage of the vehicle after the last replacement of the air-conditioning filter and the cumulative mileage of the vehicle when the air-conditioning filter is used after the last replacement of the air-conditioning filter, the process of determining the fourth aging rate of the air-conditioning filter based on the cumulative mileage of the vehicle after the last replacement of the air-conditioning filter is described in detail.

[0123] It should be noted that after each replacement of the air conditioning filter, the vehicle can usually travel a certain distance while the air conditioning filter is in a healthy state. In other words, the performance of the air conditioning filter will decrease as the cumulative mileage of the vehicle increases after the last replacement of the air conditioning filter. That is, in a possible implementation, the ratio between the cumulative mileage of the vehicle after the last replacement of the air conditioning filter and the first reference mileage can be calculated to obtain a first ratio, and the first ratio is determined as the fourth aging rate.

[0124] Among them, the first benchmark mileage is the maximum mileage allowed for the vehicle after each replacement of the air-conditioning filter. The benchmark mileage is pre-set by the developer based on the life of the air-conditioning filter and saved in the vehicle's internal memory.

[0125] Exemplarily, when the first benchmark mileage is 10,000 km and the cumulative mileage of the vehicle after the last replacement of the air-conditioning filter is 8,000 km, the ratio between the first benchmark mileage (8,000 km) and the cumulative mileage of the vehicle after the last replacement of the air-conditioning filter (10,000 km) can be calculated, that is, the first ratio = 8,000 km / 1,000 km = 0.8, and the first ratio (0.8) is determined as the fourth aging rate.

[0126] It should be noted that in order to avoid complex mathematical relationships, the maximum ratio of the cumulative mileage of the vehicle after the last replacement of the air-conditioning filter to the first benchmark mileage is 1, that is, when the cumulative mileage of the vehicle after the last replacement of the air-conditioning filter is greater than the first benchmark mileage, the maximum value of the fourth aging rate is 1.

[0127] After introducing the process of determining the fourth aging rate of the air-conditioning filter based on the cumulative mileage of the vehicle after the last replacement of the air-conditioning filter, the process of determining the fourth aging rate of the air-conditioning filter based on the cumulative mileage of the vehicle when using the air-conditioning filter after the last replacement of the air-conditioning filter is introduced in detail.

[0128] Similarly, each time the vehicle replaces the air-conditioning filter, it can usually use the air-conditioning filter to travel a certain distance while the air-conditioning filter is in a healthy state. In other words, the performance of the air-conditioning filter will decrease with the increase of the cumulative mileage of the vehicle when the air-conditioning filter was used after the last replacement of the air-conditioning filter. That is, in one possible implementation, the ratio between the cumulative mileage of the vehicle when the air-conditioning filter was used after the last replacement of the air-conditioning filter and the second benchmark mileage can be calculated to obtain the second ratio, and the second ratio is determined as the fourth aging rate.

[0129] Among them, the second benchmark mileage is the longest mileage allowed for the vehicle to travel when using the air-conditioning filter after each replacement of the air-conditioning filter. The benchmark mileage is pre-set by the developer according to the life of the air-conditioning filter and saved in the internal memory of the vehicle. It should be noted that since the second benchmark mileage is the longest mileage allowed for the vehicle to travel when using the air-conditioning filter after the vehicle replaces the air-conditioning filter, and the first benchmark mileage is the longest mileage allowed for the vehicle to travel after the vehicle replaces the air-conditioning filter, the second benchmark mileage is less than the first benchmark mileage. For example, when the first benchmark mileage is 10,000 km, the second benchmark mileage can be 5,000 km, 6,000 km or 7,000 km, etc., and this embodiment of the present application is not limited to this.

[0130] Exemplarily, when the second benchmark mileage is 5000 km and the cumulative mileage of the vehicle when using the air-conditioning filter after the last replacement of the air-conditioning filter is 4000 km, the ratio between the second benchmark mileage (5000 km) and the cumulative mileage (4000 km) of the vehicle when using the air-conditioning filter after the last replacement of the air-conditioning filter can be calculated, that is, the second ratio = 4000 km / 5000 km = 0.8, and the second ratio (0.8) is determined as the fourth aging rate.

[0131] Similarly, in order to avoid complex mathematical relationships, the maximum ratio of the cumulative mileage of the vehicle when using the air-conditioning filter after the last replacement of the air-conditioning filter to the second benchmark mileage is also 1, that is, when the cumulative mileage of the vehicle when using the air-conditioning filter after the last replacement of the air-conditioning filter is greater than the second benchmark mileage, the maximum value of the fourth aging rate is 1.

[0132] In the third part, the first aging rate, the second aging rate, the third aging rate and the fourth aging rate are summed to obtain a target aging rate.

[0133] Exemplarily, when the first aging rate is 0.4, the second aging rate is 0.3, the third aging rate is 0.5, and the fourth aging rate is 0.8, the first aging rate (0.4), the second aging rate (0.3), the third aging rate (0.5), and the fourth aging rate (0.5) can be summed, that is, 0.4+0.3+0.5+0.8=2, and the sum (2) is determined as the target aging rate.

[0134] The following is divided into three steps to introduce in detail the specific implementation process of obtaining the target aging rate.

[0135] Step (1), summing the third aging rate and the fourth aging rate to obtain a sixth aging rate of the air conditioning filter element, where the sixth aging rate is used to indicate the effect of the service life data of the air conditioning filter element on the performance of the air conditioning filter element.

[0136] Exemplarily, when the third aging rate is 0.5 and the fourth aging rate is 0.8, the third aging rate (0.5) and the fourth aging rate (0.8) may be added, ie, 0.5+0.8=1.3, and the sum (1.3) may be determined as the sixth aging rate.

[0137] Step (2), respectively multiplying the first aging rate, the second aging rate and the sixth aging rate by their corresponding preset weights to obtain the adjusted first aging rate, the second aging rate and the sixth aging rate.

[0138] It should be noted that after obtaining the sixth aging rate used to represent the impact of the air-conditioning filter's usage cycle data on the performance of the air-conditioning filter, taking into account that the first aging rate, the second aging rate and the sixth aging rate have different impacts on the performance of the air-conditioning filter, in order to improve the accuracy of the target aging rate obtained by combining the first aging rate, the second aging rate and the sixth aging rate, in a possible implementation, the first aging rate, the second aging rate and the sixth aging rate can be respectively assigned corresponding weights, and the first aging rate, the second aging rate and the sixth aging rate can be multiplied by their respective corresponding preset weights to obtain the adjusted first aging rate, the second aging rate and the sixth aging rate, so that the target aging rate can be obtained subsequently based on the adjusted first aging rate, the second aging rate and the sixth aging rate.

[0139] For example, a first weight is assigned to the first aging rate, a second weight is assigned to the second aging rate, and a third weight is assigned to the sixth aging rate. Then, the first aging rate is multiplied by the first weight to obtain the adjusted first aging rate, the second aging rate is multiplied by the second weight to obtain the adjusted second aging rate, and the sixth aging rate is multiplied by the third weight to obtain the adjusted sixth aging rate.

[0140] It should be noted that since the health status data of the vehicle air conditioner can directly reflect the performance of the air conditioning filter, and the health status data of the vehicle air conditioner is not affected by the official maintenance record, the first aging rate obtained based on the health status data of the vehicle air conditioner can be given the highest weight of the three weights, that is, the first weight is greater than the second weight and the third weight.

[0141] In addition, since the obtained usage cycle data of the air-conditioning filter (i.e., the usage time of the air-conditioning filter and the mileage of the vehicle) is affected by unofficial maintenance records, the obtained usage cycle data of the air-conditioning filter may have a large deviation from the actual usage cycle data of the air-conditioning filter. Therefore, in order to minimize the impact of this deviation on the timing of determining whether it is necessary to remind the user to replace the air-conditioning filter, in an embodiment of the present application, the sixth aging rate obtained based on the usage cycle data of the air-conditioning filter can be given the lowest weight of the three weights, that is, the third weight is less than the second weight and the third weight.

[0142] Finally, since the working data of the vehicle air conditioner cannot directly reflect the performance of the air conditioning filter, but the working data of the vehicle air conditioner is not affected by the official maintenance record, the second aging rate obtained based on the working data of the vehicle air conditioner can be given a second weight greater than the third weight and less than the first weight.

[0143] Exemplarily, the first weight assigned to the first aging rate is 0.7, the second weight assigned to the second aging rate is 0.2, and the first weight assigned to the sixth aging rate is 0.1.

[0144] Step (3), summing the adjusted first aging rate, second aging rate and sixth aging rate to obtain a target aging rate.

[0145] Exemplarily, when the first aging rate is 0.4, the first weight is 0.7, the second aging rate is 0.3, the second weight is 0.2, the sixth aging rate is 1.3, and the third weight is 0.1, the adjusted first aging rate is 0.4×0.7=0.28, the adjusted second aging rate is 0.3×0.2=0.06, and the adjusted sixth aging rate is 1.3×0.1=0.13. Then, the adjusted first aging rate (0.28), the adjusted second aging rate (0.06) and the adjusted sixth aging rate (0.13) are summed to obtain the final target aging rate, that is, the target aging rate=0.28+0.06+0.13=0.47.

[0146] Step 203: When the target aging rate of the air conditioning filter element is greater than the first aging threshold, output a prompt message for replacing the air conditioning filter element.

[0147] Among them, the first aging threshold is pre-set by the developer according to experimental data and stored in the internal memory of the vehicle. For example, the first aging threshold is 0.5, 0.6 or 0.65, etc., which is not limited in the embodiment of the present application.

[0148] The prompt message for replacing the air conditioning filter may be text or voice, etc. For example, the prompt message may be text displayed on the vehicle's central control electronic screen, "Please replace the air conditioning filter in time" or "The air conditioning filter has poor performance, please replace the air conditioning filter", etc., which is not limited in the present embodiment of the application.

[0149] Exemplarily, when the first aging threshold is 0.6 and the target aging rate of the air-conditioning filter is determined to be 0.66, since the target aging rate (0.66) is greater than the first aging threshold (0.6), in this case the vehicle controller will control the vehicle's central control electronic screen to output a prompt message for replacing the air-conditioning filter.

[0150] In summary, the air conditioning reminder method provided by the present application can determine the target aging rate of the air conditioning filter element by acquiring the operating status data of the vehicle air conditioning and the service cycle data of the air conditioning filter element of the vehicle air conditioning, and output the prompt information of replacing the air conditioning filter element when the target aging rate of the air conditioning filter element is greater than the first aging threshold. Since the target aging rate of the air conditioning filter element is jointly determined by the operating status data of the vehicle air conditioning and the service cycle data of the air conditioning filter element, and the operating status data of the vehicle air conditioning is not affected by the official maintenance record, it can improve the accuracy of the target aging rate of the air conditioning filter element determined when there is a large deviation between the service cycle data of the acquired air conditioning filter element and the actual service cycle data, that is, it can improve the accuracy of the target aging rate of the air conditioning filter element determined when the user replaces the air conditioning filter element through an unofficial authorized vehicle repair shop, thereby improving the accuracy of the timing of reminding the user to replace the air conditioning filter element, avoiding the waste of resources when the air conditioning filter element is replaced too early, and affecting the air quality in the car when the air conditioning filter element is replaced too late.

[0151] Considering that the air conditioning filter has just been replaced, the target aging rate determined at this time cannot reflect the performance of the air conditioning filter in time. In a possible implementation, when the state value of the air conditioning filter is the second flag bit (1), that is, when there is no abnormality in the air conditioning filter and the target aging rate of the air conditioning filter is greater than the second aging threshold, the prompt information for replacing the air conditioning filter may not be output. Since there is no abnormality in the air conditioning filter, it indicates that the air conditioning filter has just been replaced. The target aging rate determined at this time cannot reflect the performance of the air conditioning filter in time. Therefore, in this case, the prompt information for replacing the air conditioning filter may not be output, so as to avoid the air conditioning filter being replaced too early and causing waste of resources. Among them, the second aging threshold is a threshold greater than the first aging threshold set in advance by the developer based on experimental data and stored in the internal memory of the vehicle. For example, when the first threshold is 0.6, the second aging threshold may be 0.7, 0.8 or 0.85, etc., and the embodiments of the present application do not limit this. When the status value of the air conditioning filter is the first flag bit (0), that is, there is an abnormality in the air conditioning filter, and the target aging rate of the air conditioning filter is greater than the first aging threshold, it indicates that the air conditioning filter has not been replaced, and the performance of the air conditioning filter is very poor at this time. In this case, it is necessary to output a prompt message for replacing the air conditioning filter to remind the user to replace the air conditioning filter, so as to avoid affecting the air quality in the car when the air conditioning filter is replaced too late.
