Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicles, and more particularly, to a reminding method of an air conditioner and a vehicle in the technical field of vehicles. BACKGROUND

[0002] The air conditioner filter element is the first line of defense for filtering air impurities in the automobile air conditioning system, and if not replaced in time, it can easily cause the air conditioner filter element to be heavily soiled, and even worse, the air conditioner filter element can mildew and cause certain harm to the human body. Therefore, how to improve the accuracy of determining the replacement time of the air conditioner filter element is particularly important.

[0003] At present, whether to remind the user to replace the air conditioner filter element is determined based on the accumulated driving mileage and the accumulated time duration after the air conditioner filter element is replaced last time on the vehicle. However, since the time when the air conditioner filter element is replaced last time on the vehicle is only updated when the user replaces the air conditioner filter element through an officially authorized vehicle repair shop, i.e., when the user replaces the air conditioner filter element through a non-officially authorized vehicle repair shop, the time is not updated, so there is a large deviation between the accumulated driving mileage and the accumulated time duration after the air conditioner filter element is replaced last time on the vehicle obtained and the actual accumulated driving mileage and the accumulated time duration after the air conditioner filter element is replaced last time on the vehicle, thereby leading to inaccurate timing of reminding the user to replace the air conditioner filter element. SUMMARY

[0004] The present application provides a reminding method of an air conditioner and a vehicle, which can improve the accuracy of the timing of reminding the user to replace the air conditioner filter element, thereby avoiding the situation of wasting resources when the air conditioner filter element is replaced too early and affecting the air quality in the vehicle when the air conditioner filter element is replaced too late.

[0005] In a first aspect, a reminding method of an air conditioner is provided, which includes: obtaining running state data of a vehicle-mounted air conditioner and usage cycle data of an air conditioner filter element of the vehicle-mounted air conditioner; determining a target aging rate of the air conditioner filter element according to the running state data of the vehicle-mounted air conditioner and the usage cycle data of the air conditioner filter element; and outputting a prompt information of replacing the air conditioner filter element in a case where the target aging rate of the air conditioner filter element is greater than a first aging threshold.

[0006] In the technical solution, the target aging rate of the air conditioner filter element is determined based on the obtained running state data of the vehicle-mounted air conditioner and the use cycle data of the air conditioner filter element, and the prompt information for replacing the air conditioner filter element is output when the target aging rate of the air conditioner filter element is greater than the first aging threshold. Since the target aging rate of the air conditioner filter element is determined based on the running state data of the vehicle-mounted air conditioner and the use cycle data of the air conditioner filter element, and the running state data of the vehicle-mounted air conditioner is not affected by official maintenance records, the accuracy of the target aging rate of the air conditioner filter element can be improved in the case that there is a large deviation between the obtained use cycle data of the air conditioner filter element and the actual use cycle data, that is, the accuracy of the target aging rate of the air conditioner filter element can be improved in the case that the user replaces the air conditioner filter element through a non-officially authorized vehicle repair shop, so that the accuracy of the timing for prompting the user to replace the air conditioner filter element can be improved, and resource waste caused by early replacement of the air conditioner filter element and the influence on the air quality in the vehicle caused by late replacement of the air conditioner filter element can be avoided.

[0007] With reference to the first aspect and the above implementation manners, in some possible implementation manners, the running state data of the vehicle-mounted air conditioner includes health state data of the vehicle-mounted air conditioner and working data of the vehicle-mounted air conditioner, and the use cycle data of the air conditioner filter element includes a use duration of the air conditioner filter element and a driving mileage of the vehicle; the target aging rate of the air conditioner filter element is determined based on the running state data of the vehicle-mounted air conditioner and the use cycle data of the air conditioner filter element, including: the health state data of the vehicle-mounted air conditioner and the working data of the vehicle-mounted air conditioner are processed respectively to obtain a first aging rate and a second aging rate of the air conditioner filter element, the first aging rate is used to represent the working state and health degree of the air conditioner filter element in the current environment, and the second aging rate is used to represent the wear degree of the air conditioner filter element in the actual working process; the use duration of the air conditioner filter element and the driving mileage of the vehicle are processed respectively to obtain a third aging rate and a fourth aging rate of the air conditioner filter element, the third aging rate is used to represent the influence of the accumulated dirt of the air conditioner filter element in the use process on the performance of the air conditioner filter element, and the fourth aging rate is used to represent the influence of the driving mileage of the vehicle on the performance of the air conditioner filter element; and the first aging rate, the second aging rate, the third aging rate and the fourth aging rate are summed to obtain the target aging rate.

[0008] With reference to the first aspect and the above implementation manners, in some possible implementation manners, the health state data of the vehicle-mounted air conditioner includes a current alarm state of the vehicle-mounted air conditioner and air quality of an environment in which the vehicle-mounted air conditioner is located; the health state data of the vehicle-mounted air conditioner is processed to obtain the first aging rate of the air conditioner filter element, including: the air quality of the environment in which the vehicle-mounted air conditioner is located is compared with a corresponding target air quality index to obtain a first comparison result, and a threshold corresponding to the first comparison result is determined as a fifth aging rate of the air conditioner filter element.

[0009] The current alarm state of the vehicle-mounted air conditioner is compared with a target state to obtain a second comparison result, and a flag bit corresponding to the second comparison result is determined as a state value of the air conditioner filter element. The target state includes a first state and a second state. The first state is used to indicate that the air conditioner filter element has an abnormality, and the second state is used to indicate that the air conditioner filter element has no abnormality. The fifth aging rate and the state value of the air conditioner filter element are summed to obtain a first aging rate.

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

[0011] In combination with the first aspect and the above implementation manners, in some possible implementation manners, the usage data of the vehicle-mounted air conditioner includes a starting time length, a starting frequency, and an average set temperature of the vehicle-mounted air conditioner; and the second aging rate is obtained by comparing the usage data of the vehicle-mounted air conditioner in the preset time period with a corresponding usage threshold to obtain a third comparison result, and determining a threshold corresponding to the third comparison result as the second aging rate, including: comparing the starting time length, the starting frequency, and the average set temperature of the vehicle-mounted air conditioner in the preset time period with corresponding target thresholds respectively to obtain a fourth comparison result, and determining a threshold corresponding to the fourth comparison result as the second aging rate. The corresponding target threshold is the starting time length, the starting frequency, and the average set temperature of the vehicle-mounted air conditioner in a previous preset time period.

[0012] In combination with the first aspect and the above implementation manners, in some possible implementation manners, the usage time length of the air conditioner filter element is a cumulative time length after the vehicle last replaced the air conditioner filter element or a cumulative usage time length of the air conditioner filter element after the vehicle last replaced the air conditioner filter element; and the third aging rate of the air conditioner filter element is obtained by processing the usage time length of the air conditioner filter element, including: comparing the cumulative time length after the vehicle last replaced the air conditioner filter element with a corresponding first time threshold to obtain a fifth comparison result, and determining a threshold corresponding to the fifth comparison result as the third aging rate; or comparing the cumulative usage time length of the air conditioner filter element after the vehicle last replaced the air conditioner filter element with a corresponding second time threshold to obtain a sixth comparison result, and determining a threshold corresponding to the sixth comparison result as the third aging rate.

[0013] In a possible implementation, the driving mileage of the vehicle is the cumulative driving mileage after the air conditioner filter element is replaced last time or the cumulative driving mileage when the air conditioner filter element is used after the air conditioner filter element is replaced last time; the fourth aging rate of the air conditioner filter element is obtained by processing the driving mileage of the vehicle, including: calculating a ratio between the cumulative driving mileage after the air conditioner filter element is replaced last time and a first reference mileage, to obtain a first ratio, and determining the first ratio as the fourth aging rate, the first reference mileage being the longest mileage allowed to be driven after the air conditioner filter element is replaced each time; or calculating a ratio between the cumulative driving mileage when the air conditioner filter element is used after the air conditioner filter element is replaced last time and a second reference mileage, to obtain a second ratio, and determining the second ratio as the fourth aging rate, the second reference mileage being the longest mileage allowed to be driven when the air conditioner filter element is used after the air conditioner filter element is replaced each time.

[0014] In a possible implementation, the target aging rate is obtained by summing the first aging rate, the second aging rate, the third aging rate and the fourth aging rate, including: summing the third aging rate and the fourth aging rate to obtain a sixth aging rate of the air conditioner filter element, the sixth aging rate being used to represent the influence of the use period data of the air conditioner filter element on the performance of the air conditioner filter element; multiplying the first aging rate, the second aging rate and the sixth aging rate by respective preset weights to obtain adjusted first aging rate, second aging rate and sixth aging rate; and summing the adjusted first aging rate, second aging rate and sixth aging rate to obtain the target aging rate.

[0015] In the above technical solution, after the sixth aging rate representing the influence of the driving mileage of the vehicle and the use time of the air conditioner filter element on the performance of the air conditioner filter element is obtained, the first aging rate, the second aging rate and the sixth aging rate are considered to have different influences on the performance of the air conditioner filter element, that is, respective weights can be set for the first aging rate, the second aging rate and the sixth aging rate according to the size of the influence on the performance of the air conditioner filter element, 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 respective preset weights to obtain adjusted first aging rate, second aging rate and sixth aging rate, and the adjusted first aging rate, second aging rate and sixth aging rate are summed to obtain the target aging rate, so as to ensure the accuracy of the determined target aging rate.

[0016] In a possible implementation, in a case where the target aging rate of the air filter element is greater than the first aging threshold, the outputting of the prompt information for replacing the air filter element comprises: in a case where the state value of the air filter element is the second flag bit and the target aging rate of the air filter element is greater than a second aging threshold, the second aging threshold being greater than the first aging threshold, and the second flag bit being used to indicate that the air filter element is normal, the prompt information for replacing the air filter element is not outputted; in a case where the state value of the air filter element is the first flag bit and the target aging rate of the air filter element is greater than the first aging threshold, the first flag bit being used to indicate that the air filter element is abnormal, the prompt information for replacing the air filter element is outputted.

[0017] In the technical solution, in a case where the state value of the air filter element is the second flag bit, i.e., the air filter element is normal, and the target aging rate of the air filter element is greater than the second aging threshold, the prompt information for replacing the air filter element can not be outputted. Since the air filter element is normal, it indicates that the air filter element is just replaced. At this time, the target aging rate determined cannot timely reflect the performance of the air filter element. Therefore, in this case, the prompt information for replacing the air filter element can not be outputted, so as to avoid that the air filter element is replaced too early and resources are wasted. In a case where the state value of the air filter element is the first flag bit, i.e., the air filter element is abnormal, and the target aging rate of the air filter element is greater than the first aging threshold, it indicates that the air filter element is not replaced, and at this time, the performance of the air filter element is very poor. In this case, the prompt information for replacing the air filter element needs to be outputted, so as to remind the user to replace the air filter element, thereby avoiding that the air filter element is replaced too late and the air quality in the vehicle is affected.

[0018] In a second aspect, a reminding device of an air conditioner is provided, and the device comprises:

[0019] The obtaining module is configured to obtain running state data of the vehicle-mounted air conditioner and usage cycle data of an air filter element of the vehicle-mounted air conditioner.

[0020] The determining module is configured to determine a target aging rate of the air filter element according to the running state data of the vehicle-mounted air conditioner and the usage cycle data of the air filter element.

[0021] The outputting module is configured to output prompt information for replacing the air filter element in a case where the target aging rate of the air filter element is greater than a first aging threshold.

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

[0029] The technical solutions in the present application will be described clearly and thoroughly in combination with the drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " represents the meaning of or, for example, A / B can represent A or B: "and / or" in the text only describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which means that there are three cases of A alone, A and B together, and B alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0030] Hereinafter, the terms "first" and "second" are only used for description purposes, and cannot be understood as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined with "first" and "second" can explicitly or implicitly include one or more features.

[0031] The air conditioner filter core is the first line of defense for filtering air impurities in the automobile air conditioning system. If it is not replaced in time, it will cause the air conditioner filter core to be seriously dirty, and even worse, the air conditioner filter core will be moldy and cause certain harm to the human body. Therefore, how to improve the accuracy of determining the replacement time of the air conditioner filter core is particularly important.

[0032] Currently, whether to remind the user to replace the air conditioner filter is determined based on the accumulated driving distance and the accumulated time duration after the air conditioner filter is replaced last time on the vehicle. However, the time when the air conditioner filter is replaced last time on the vehicle is only updated when the user replaces the air conditioner filter through an officially authorized vehicle repair shop, that is, when the user replaces the air conditioner filter through a non-officially authorized vehicle repair shop, the time is not updated, so there is a large deviation between the accumulated driving distance and the accumulated time duration after the air conditioner filter is replaced last time on the vehicle obtained by the vehicle and the actual accumulated driving distance and the accumulated time duration after the air conditioner filter is replaced last time on the vehicle, thereby causing the timing of reminding the user to replace the air conditioner filter to be not accurate enough.

[0033] Based on the above problems, the present application provides a reminding method of an air conditioner, which can improve the accuracy of the timing of reminding the user to replace the air conditioner filter, thereby avoiding the waste of resources when the air conditioner filter is replaced too early and the impact on the air quality in the vehicle when the air conditioner filter is replaced too late.

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

[0035] Exemplarily, as shown in Figure 1 , the implementation environment includes a vehicle control unit (VCU) 101 and an air conditioner management system 102.

[0036] The vehicle control unit 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 control unit can obtain running state data of the vehicle-mounted air conditioner and usage period data of the air conditioner filter of the vehicle-mounted air conditioner, and determine whether to output a prompt information for replacing the air conditioner filter based on the data.

[0037] In some embodiments, the vehicle control unit 101 can receive the running state data of the vehicle-mounted air conditioner and the usage period data of the air conditioner filter of the vehicle-mounted air conditioner collected by the air conditioner management system 102, and determine the health status of the air conditioner filter, that is, the target aging rate of the air conditioner filter, based on the data, so as to determine whether to output the prompt information for replacing the air conditioner filter based on the target aging rate.

[0038] The method of an embodiment of the present application will be described in detail below. Figure 2

[0039] Figure 2 is a schematic flowchart of a reminding method of an air conditioner provided by an embodiment of the present application.

[0040] Exemplarily, as shown in Figure 2 , taking the vehicle control unit as an example of the execution subject, the method 200 includes the following steps 201-203:​

[0041] In step 201, the running state data of the vehicle-mounted air conditioner and the use cycle data of the air conditioner filter element of the vehicle-mounted air conditioner are acquired.

[0042] In a possible implementation, the vehicle control unit can acquire the running state data of the vehicle-mounted air conditioner and the use cycle data of the air conditioner filter element of the vehicle-mounted air conditioner from the air conditioner management system through a Controller Area Network (CAN) bus.

[0043] In step 202, the target aging rate of the air conditioner filter element is determined according to the running state data of the vehicle-mounted air conditioner and the use cycle data of the air conditioner filter element.

[0044] Specifically, after the running state data of the vehicle-mounted air conditioner and the use cycle data of the air conditioner filter element of the vehicle-mounted air conditioner are acquired, the vehicle control unit can determine the health state of the air conditioner filter element, i.e., the target aging rate of the air conditioner filter element, according to the running state data of the vehicle-mounted air conditioner and the use cycle data of the air conditioner filter element of the vehicle-mounted air conditioner, so as to subsequently judge whether a prompt information of replacing the air conditioner filter element needs to be output based on the target aging rate.

[0045] In a possible implementation, the running state data of the vehicle-mounted air conditioner includes health state data of the vehicle-mounted air conditioner and working data of the vehicle-mounted air conditioner, and the use cycle data of the air conditioner filter element includes a use duration of the air conditioner filter element and a driving mileage of the vehicle.

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

[0047] The first part is to process the health state data of the vehicle-mounted air conditioner and the working data of the vehicle-mounted air conditioner respectively to obtain a first aging rate and a second aging rate of the air conditioner filter element, the first aging rate is used to represent the working state and health degree of the air conditioner filter element under the current environment, and the second aging rate is used to represent the wear degree of the air conditioner filter element in the actual working process.

[0048] The following first introduces the specific implementation of obtaining the first aging rate of the air conditioner filter element in detail.

[0049] The health state data of the vehicle air conditioner can include a current alarm state of the vehicle air conditioner and air quality of an environment in which the vehicle air conditioner is located. In a possible implementation, the health state data of the vehicle air conditioner is processed to obtain a first aging rate of the air conditioner filter, including: 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 corresponding to the first comparison result as a fifth aging rate of the air conditioner filter; comparing the current alarm state of the vehicle air conditioner with a target state to obtain a second comparison result, and determining a flag bit corresponding to the second comparison result as a state value of the air conditioner filter, the target state including a first state and a second state, the first state being used to indicate that the air conditioner filter has an abnormality, and the second state being used to indicate that the air conditioner filter has no abnormality; and summing the fifth aging rate and the state value of the air conditioner filter to obtain the first aging rate.

[0050] The fifth aging rate has a value range of 0-1, and the greater 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 conditioner filter is.

[0051] How to obtain the current alarm state of the vehicle air conditioner and the air quality of the environment in which the vehicle air conditioner is located is described below.

[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 being used to indicate that the air conditioner filter has an abnormality, and the second state being used to indicate that the air conditioner filter has no abnormality. The abnormality of the air conditioner filter can be understood as blockage of the air conditioner filter.

[0053] It should be noted that the air conditioner management system has a fault detection module, which can detect various abnormal conditions of the vehicle air conditioner, generate an alarm signal, and transmit the alarm signal to the vehicle controller through a 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 conditioner according to the alarm signal, and thus determine the current alarm state (first state / second state) of the vehicle air conditioner, i.e., determine whether the air conditioner filter currently has an abnormality, in a possible implementation, the alarm signal can indicate a specific fault type (for example, the alarm signal can indicate blockage of the air conditioner filter, a temperature sensor fault, or a fan fault, etc.), so that the vehicle controller can determine the current alarm state of the vehicle air conditioner according to the alarm signal.

[0054] It can be understood that the air quality of the environment where the vehicle air conditioner is located, i.e., the air quality inside the vehicle, is determined by the concentration of particulate matter (PM2.5) with a diameter less than or equal to 2.5 μm, carbon dioxide (CO2), and volatile organic compounds (VOCs). Specifically, when determining the air quality of the environment where 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 according to the highest air quality index. That is, in the embodiments of the present application, the concentrations of PM2.5, CO2, and VOCs inside the vehicle need to be obtained first, and the corresponding conversion table is used to convert them into air quality indexes, and finally the highest air quality index is determined as the air quality of the environment where the vehicle air conditioner is located.

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

[0056] The concentration conversion table of PM2.5, CO2, and VOCs is set in advance by the developer according to the national standard and stored in the internal memory of the vehicle.

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

[0058] Table 1

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

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

[0061] Table 2

[0062]

[0063]

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

[0065] Table 3

[0066] 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 obtained concentration of PM2.5 is 120 μg / m 3 , the concentration of CO2 is 440 ppm, and the concentration of VOCs is 0.2 mg / m 3, the PM2.5 concentration is 120 μg / m3, the CO2 concentration is 440 ppm, and the VOCs concentration is 0.2 mg / m3, the corresponding air quality index is 180, and the air quality index corresponding to the PM2.5 concentration of 120 μg / m3, the CO2 concentration of 440 ppm, and the VOCs concentration of 0.2 mg / m3 is 80. 3 The corresponding air quality index is 180, and the air quality index corresponding to the CO2 concentration of 440 ppm and the VOCs concentration of 0.2 mg / m3 is 80. 3 The corresponding air quality index is 35, and the highest air quality index, i.e., the air quality index corresponding to the PM2.5 concentration of 120 μg / m3, the CO2 concentration of 440 ppm, and the VOCs concentration of 0.2 mg / m3, is determined to be the air quality of the environment in which the vehicle-mounted air conditioner is located. 3 The corresponding air quality index (180) is determined to be the air quality of the environment in which the vehicle-mounted air conditioner is located.

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

[0069] It should be noted that the air quality of the environment in which the vehicle-mounted air conditioner is located, i.e., the concentrations of PM2.5, CO2, and VOCs in the environment in which the vehicle-mounted air conditioner is located, can reflect the performance of the air conditioner filter element, i.e., the higher the air quality of the environment in which the vehicle-mounted air conditioner is located, the higher the performance of the air conditioner filter element; the lower the air quality of the environment in which the vehicle-mounted air conditioner is located, the lower the performance of the air conditioner filter element, i.e., in a possible implementation, the air quality of the environment in which the vehicle-mounted air conditioner is located can be compared with the first air quality index and the second air quality index, in the case where the air quality is less than or equal to the first air quality index, the first threshold is determined to be the fifth aging rate; in the case where the air quality is greater than the first air quality index and less than the second air quality index, the second threshold is determined to be the fifth aging rate, the second threshold being greater than the first threshold; in the case where the air quality is greater than the second air quality index, the third threshold is determined to be the fifth aging rate, the third threshold being greater than the second threshold.

[0070] The first air quality index and the second air quality index are set by the developer in advance according to experimental data and stored in the internal memory of the vehicle, for example, the first air quality index is 50 and the second air quality index is 150, and the number and size of the set air quality indexes are not limited in the embodiments of the present application.

[0071] It should be noted that in the case where 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-mounted air conditioner is located is good, i.e., the performance of the air conditioner filter element is good, i.e., in this case, the first threshold can be determined to be the second aging rate. The first threshold is the minimum value of the fifth aging rate. For example, when the minimum value of the fifth aging rate is 0, the first threshold is also 0, and in this case, the first threshold (0) is determined to be the fifth aging rate.

[0072] In the case that 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 where the vehicle air conditioner is located is poor, i.e. the performance of the air conditioner filter core is poor at this time, and 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 conditioner filter core. For example, when the second threshold value greater than the first threshold value is 0.4, the second threshold value (0.4) will be determined as the fifth aging rate in this case to increase the second aging rate of the air conditioner filter core.

[0073] In the case that the air quality is greater than the second air quality index, it indicates that the air quality of the environment where the vehicle air conditioner is located is very poor, i.e. the performance of the air conditioner filter core is very poor at this time, and in this case, the 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 conditioner filter core, thereby ensuring the accuracy of the determined target aging rate. For example, when the third threshold value greater than the second threshold value is 1, the third threshold value (1) will be determined as the fifth aging rate in this case to further increase the fifth aging rate of the air conditioner filter core, thereby ensuring the accuracy of the determined target aging rate.

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

[0075] After introducing the process of determining the fifth aging rate of the air conditioner filter core, the process of determining the state value of the air conditioner filter core will be introduced in detail.

[0076] As can be seen from the above examples, the current alarm state of the vehicle air conditioner includes a first state for indicating that the air conditioner filter core has an abnormality and a second state for indicating that the air conditioner filter core has no abnormality. 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 in the case that the current alarm state of the vehicle air conditioner is the first state, i.e. in the case that the air conditioner filter core has an abnormality, the first flag bit is determined as the state value of the air conditioner filter core; in the case that the current alarm state of the vehicle air conditioner is the second state, i.e. in the case that the air conditioner filter core has no abnormality, the second flag bit is determined as the state value of the air conditioner filter core.

[0077] For example, the first flag is 0, the first flag is 1, in the case of the presence of an abnormality of the air conditioner filter element, the first flag (0) is determined as the state value of the air conditioner filter element; in the case of the absence of an abnormality of the air conditioner filter element, the second flag (1) is determined as the state value of the air conditioner filter element.

[0078] After obtaining the fifth aging rate of the air conditioner filter element and the state value of the air conditioner filter element, the process of determining the first aging rate in detail is as follows.

[0079] In one possible implementation, after obtaining the fifth aging rate of the air conditioner filter element and the state value of the air conditioner filter element, the fifth aging rate and the state value of the air conditioner filter element can be summed to obtain the first aging rate.

[0080] For example, when the fifth aging rate is 0.4 and the state value of the air conditioner filter element is 0, the fifth aging rate (0.4) and the state value of the air conditioner filter element (0) can 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, the fifth aging rate of the air conditioner filter element and the state value of the air conditioner filter element can be respectively provided with corresponding weights, so that after obtaining the fifth aging rate of the air conditioner filter element and the state value of the air conditioner filter element, the fifth aging rate and the state value of the air conditioner filter element are respectively multiplied by the respective corresponding weights to obtain an adjusted fifth aging rate and an adjusted state value of the air conditioner filter element, and the adjusted fifth aging rate and the adjusted state value of the air conditioner filter element 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 conditioner filter element directly affects the air quality of the environment in which the vehicle-mounted air conditioner is located, i.e., the air quality of the environment in which the vehicle-mounted air conditioner is located can directly reflect the performance of the air conditioner filter element, and the current alarm state of the vehicle-mounted air conditioner is not a persistent indicator, i.e., the current alarm state of the vehicle-mounted air conditioner can only be the state of the air conditioner filter element at a certain moment, and therefore the current alarm state of the vehicle-mounted air conditioner cannot directly reflect the performance of the air conditioner filter element, i.e., in order to improve the accuracy of the determined first aging rate, the fifth aging rate determined based on the air quality of the environment in which the vehicle-mounted air conditioner is located and the state value of the air conditioner filter element determined based on the current alarm state of the vehicle-mounted air conditioner can be respectively provided with different weights (it should be understood that the weight provided for the fifth aging rate should be greater than the weight provided for the state value of the air conditioner filter element).

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

[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 can be 3 days, a week, or a month, etc., which is not limited in the present embodiment.

[0086] The second aging rate has a value range of 0 to 1. A larger second aging rate indicates a lower performance of the air conditioning filter element.

[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-conditioning, the acquired usage data of the vehicle air-conditioning can be compared with the usage data of the vehicle air-conditioning 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. In this case, the fifth threshold value 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 significantly decreased. In this case, the sixth threshold value that is less than the fifth threshold value can be determined as the second aging rate.

[0089] In a possible embodiment, 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: comparing the startup duration, startup frequency and average set temperature of the vehicle air conditioner within the preset duration with the corresponding target threshold to obtain a fourth comparison result, and determining the threshold corresponding to the fourth comparison result 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] The corresponding target threshold is the starting time, starting frequency and average set temperature of the vehicle-mounted air conditioner in the last preset time length.

[0091] The following describes how to obtain the starting time, starting frequency and average set temperature of the vehicle-mounted air conditioner.

[0092] In a possible implementation, the vehicle controller can detect the state (on and off) of the vehicle-mounted air conditioner through an air conditioner state sensor, record the starting time and starting time length of the vehicle-mounted air conditioner each time through a time sensor, detect the set temperature of the vehicle-mounted air conditioner each time through a temperature sensor, and generate a log file from the collected data (i.e., the starting time, starting time length and set temperature of the vehicle-mounted air conditioner), and store the log file in the internal memory or external storage device of the vehicle, such as an SD card or a cloud server, so that the vehicle controller can extract the required data, i.e., the starting time, starting time length and set temperature of the vehicle-mounted air conditioner each time, from the log file. After extracting the starting time, starting time length and set temperature of the vehicle-mounted air conditioner each time, the vehicle controller will accumulate the starting time and starting frequency of the vehicle-mounted air conditioner in the preset time length, and calculate the average of the set temperature of the vehicle-mounted air conditioner when starting in the preset time length.

[0093] After obtaining the starting time, starting frequency and average set temperature of the vehicle-mounted air conditioner, the process of determining the second aging rate of the air conditioner filter element is described in detail.

[0094] It should be noted that when the air conditioner filter element is seriously aged, i.e., the performance of the air conditioner filter element is very low, the user will increase the starting time, frequency and set temperature of the vehicle-mounted air conditioner, so that the temperature inside the vehicle can meet the user's own needs. That is, in the embodiments of the present application, after obtaining the usage data of the vehicle-mounted air conditioner in the preset time length, i.e., the starting time, starting frequency and average set temperature of the vehicle-mounted air conditioner in the preset time length, the starting time, starting frequency and average set temperature of the vehicle-mounted air conditioner are compared with the corresponding target threshold, so that in the case where the starting time, starting frequency and average set temperature of the vehicle-mounted air conditioner are equal to the corresponding target threshold, the seventh threshold is determined as the second aging rate; in the case where any one of the starting time, starting 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; in the case where the starting time, starting 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, in the case that the starting duration, the starting frequency and the average set temperature are all equal to the corresponding target threshold, it indicates that the user's use mode of the vehicle air conditioner has not changed (it can be understood that the user's starting duration, frequency and average set temperature of the vehicle air conditioner have not changed compared with the starting duration, frequency and average set temperature in the last preset duration), that is, the performance of the air conditioner filter core is better at this time, that is, in this case, the seventh threshold value can be determined as the second aging rate. The seventh threshold value is the minimum value of the second aging rate. For example, when the minimum value of the second aging rate is 0, the seventh threshold value is also 0, and in this case, the seventh threshold value (0) is determined as the second aging rate.

[0096] In the case that any one of the starting duration, the starting frequency and the average set temperature is less than or greater than the corresponding target threshold, it indicates that the user's use mode of the vehicle air conditioner has changed slightly, that is, the performance of the air conditioner filter core decreases slightly at this time, that is, the performance of the air conditioner filter core is poor at this time, that is, in this case, the eighth threshold value greater than the seventh threshold value can be determined as the second aging rate to increase the first aging rate of the air conditioner filter core. For example, when the eighth threshold value greater than the seventh threshold value is 0.3, the eighth threshold value (0.3) is determined as the second aging rate to increase the second aging rate of the air conditioner filter core in this case.

[0097] In the case that the starting duration, the starting frequency and the average set temperature are all less than or greater than the corresponding target threshold, it indicates that the user's use mode of the vehicle air conditioner has changed greatly, that is, the performance of the air conditioner filter core decreases significantly at this time, that is, the performance of the air conditioner filter core is very poor at this time, that is, 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 conditioner filter core, thereby ensuring the accuracy of the determined target aging rate. For example, when the ninth threshold value greater than the eighth threshold value is 1, the ninth threshold value (1) is determined as the second aging rate to further increase the second aging rate of the air conditioner filter core, thereby ensuring the accuracy of the determined target aging rate.

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

[0099] The second part respectively processes the use length of the air conditioner filter element and the driving mileage of the vehicle to obtain a third aging rate and a fourth aging rate of the air conditioner filter element, the third aging rate is used to represent the influence of the accumulated dirt of the air conditioner filter element in the use process on the performance of the air conditioner filter element, and the fourth aging rate is used to represent the influence of the driving mileage of the vehicle on the performance of the air conditioner filter element.

[0100] The third aging rate has a value range of 0-1, and the greater the fourth aging rate, the longer the use length of the air conditioner filter element, and the lower the performance of the air conditioner filter element at this time.

[0101] The fourth aging rate has a value range of 0-1, and the greater the fourth aging rate, the higher the driving mileage of the vehicle, and the lower the performance of the air conditioner filter element at this time.

[0102] Next, the specific implementation manner of obtaining the third aging rate of the air conditioner filter element is introduced in detail.

[0103] The use length of the air conditioner filter element can be the accumulated length after the vehicle last replaced the air conditioner filter element or the accumulated use length of the air conditioner filter element after the vehicle last replaced the air conditioner filter element, and in a possible implementation manner, the use length of the air conditioner filter element is processed to obtain the third aging rate of the air conditioner filter element, including: comparing the accumulated length after the vehicle last replaced the air conditioner filter element with a 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 accumulated use length of the air conditioner filter element after the vehicle last replaced the air conditioner filter element with a 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] Next, how to obtain the accumulated length after the vehicle last replaced the air conditioner filter element and the accumulated use length of the air conditioner filter element after the vehicle last replaced the air conditioner filter element is introduced.

[0105] In a possible implementation manner, the vehicle control unit can access the maintenance record of the vehicle through the database interface of the officially authorized vehicle repair shop, query the date of the vehicle last replacing the air conditioner filter element, and then calculate the accumulated length after the vehicle last replaced the air conditioner filter element according to the current date.

[0106] In a possible implementation, the vehicle controller can detect the state (on and off) of the vehicle air conditioner through an air conditioner state sensor, record the time length and starting time of each start of the vehicle air conditioner through a time sensor, and generate a log file of the starting time length and starting time of the vehicle air conditioner. The log file is stored in the internal storage of the vehicle or an external storage device such as an SD card or a cloud server, so that the vehicle controller can extract the required data, i.e., the time length and starting time of each start of the vehicle air conditioner, from the log file, and according to the current date and the date of replacing the air conditioner filter, the time length of starting the vehicle air conditioner since the last replacement of the air conditioner filter on the vehicle is accumulated, so as to obtain the time length of accumulated use of the air conditioner filter since the last replacement of the air conditioner filter on the vehicle.

[0107] After obtaining the accumulated time length since the last replacement of the air conditioner filter on the vehicle and the time length of accumulated use of the air conditioner filter since the last replacement of the air conditioner filter on the vehicle, the process of determining the third aging rate of the air conditioner filter based on the accumulated time length since the last replacement of the air conditioner filter on the vehicle is described in detail.

[0108] It should be noted that the longer the accumulated time length since the last replacement of the air conditioner filter on the vehicle, the more the performance of the air conditioner filter decreases, that is, the lower the performance of the air conditioner filter. In other words, the performance of the air conditioner filter decreases with the increase of the accumulated time length since the last replacement of the air conditioner filter on the vehicle. That is, in a possible implementation, the accumulated time length since the last replacement of the air conditioner filter on the vehicle can be compared with the third time threshold and the fourth threshold, respectively, so that the eleventh threshold is determined as the third aging rate when the accumulated time length is less than or equal to the third time threshold; the twelfth threshold is determined as the third aging rate when the accumulated time length is greater than the third time threshold and less than the fourth time threshold, the twelfth threshold being greater than the eleventh threshold; and the thirteenth threshold is determined as the third aging rate when the accumulated time length is greater than the fourth time threshold, the thirteenth threshold being greater than the twelfth threshold.

[0109] The third time threshold and the fourth time threshold are set in advance by the developer according to experimental data and stored in the internal storage of the vehicle. 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 number and size of the set time thresholds are not limited in the embodiments of the application.

[0110] It should be noted that, in the case that the cumulative duration after the last replacement of the air conditioner filter element on the vehicle is less than or equal to the third time threshold, it indicates that the air conditioner filter element has been used for a short time, i.e. the performance of the air conditioner filter element is good at this time, and the eleventh threshold value can be determined as the third aging rate. The eleventh threshold value is the minimum value of the third aging rate. For example, when the minimum value of the third aging rate is 0, the eleventh threshold value is also 0, and in this case the eleventh threshold value (0) is determined as the third aging rate.

[0111] In the case that the cumulative duration after the last replacement of the air conditioner filter element on the vehicle is greater than the third time threshold and less than the fourth time threshold, it indicates that the air conditioner filter element has been used for a long time, and at this time the performance of the air conditioner filter element decreases slightly, i.e. the performance of the air conditioner filter element is poor at this time, and in this case the twelfth threshold value greater than the eleventh threshold value can be determined as the third aging rate to increase the third aging rate of the air conditioner filter element. For example, when the twelfth threshold value greater than the eleventh threshold value is 0.5, in this case the twelfth threshold value (0.5) is determined as the third aging rate to increase the third aging rate of the air conditioner filter element.

[0112] In the case that the cumulative duration after the last replacement of the air conditioner filter element on the vehicle is greater than the fourth time threshold, it indicates that the air conditioner filter element has been used for a very long time, and at this time the performance of the air conditioner filter element decreases significantly, i.e. in this case the thirteenth threshold value greater than the twelfth threshold value can be determined as the third aging rate to further increase the third aging rate of the air conditioner filter element, thereby ensuring the accuracy of the determined target aging rate. For example, when the thirteenth threshold value greater than the twelfth threshold value is 1, in this case the thirteenth threshold value (1) is determined as the third aging rate to further increase the third aging rate of the air conditioner filter element, thereby ensuring the accuracy of the determined target aging rate.

[0113] After introducing the process of determining the third aging rate of the air conditioner filter element based on the cumulative duration after the last replacement of the air conditioner filter element on the vehicle, the process of determining the third aging rate of the air conditioner filter element based on the cumulative duration of using the air conditioner filter element after the last replacement of the air conditioner filter element on the vehicle is introduced.

[0114] Similarly, the longer the accumulated time of using the air conditioner filter element since the last time the air conditioner filter element is replaced in the vehicle, the more the performance of the air conditioner filter element decreases, i.e. the lower the performance of the air conditioner filter element. In other words, the performance of the air conditioner filter element decreases with the increase of the accumulated time of using the air conditioner filter element since the last time the air conditioner filter element is replaced in the vehicle, i.e. in a possible implementation, the accumulated time of using the air conditioner filter element since the last time the air conditioner filter element is replaced in the vehicle can be compared with the fifth time threshold and the sixth time threshold respectively, so that the fourteenth threshold is determined as the third aging rate in the case that the accumulated time of using the air conditioner filter element is less than or equal to the fifth time threshold, the fifteenth threshold is determined as the third aging rate in the case that the accumulated time of using the air conditioner filter element is greater than the fifth time threshold and less than the sixth time threshold, the fifteenth threshold is greater than the fourteenth threshold; the sixteenth threshold is determined as the third aging rate in the case that the accumulated time of using the air conditioner filter element is greater than the sixth time threshold, the sixteenth threshold is greater than the fifteenth threshold.

[0115] The fifth time threshold and the sixth time threshold are set in advance by the developer according to experimental data and stored in the internal memory of the vehicle. It can be understood that the increase of the accumulated time of using the air conditioner filter element since the last time the air conditioner filter element is replaced in the vehicle also increases the accumulated time of using the air conditioner filter element since the last time the air conditioner filter element is replaced in the vehicle, i.e. 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 respectively, for example, the fifth time threshold can also be 183 days, the sixth time threshold can also be 365, etc., which are not limited in the embodiments of the present application.

[0116] It should be noted that the above implementation and principle of comparing the accumulated time of using the air conditioner filter element since the last time the air conditioner filter element is replaced in the vehicle with the fifth time threshold and the sixth time threshold respectively, and determining the corresponding threshold according to the comparison result and determining the corresponding threshold as the third aging rate are the same as the above implementation and principle of comparing the accumulated time of using the air conditioner filter element since the last time the air conditioner filter element is replaced in the vehicle with the third time threshold and the fourth time threshold respectively, and determining the corresponding threshold according to the comparison result and determining the corresponding threshold as the third aging rate, which can be referred to the above embodiments and will not be described here.

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

[0118] The cumulative mileage of the vehicle after the last time the air conditioner filter is replaced is the cumulative mileage of the vehicle after the last time the air conditioner filter is replaced, or the cumulative mileage of the vehicle when the air conditioner filter is used after the last time the air conditioner filter is replaced. In a possible implementation, the cumulative mileage of the vehicle is processed to obtain the fourth aging rate of the air conditioner filter, including: calculating the ratio between the cumulative mileage of the vehicle after the last time the air conditioner filter is replaced and the first reference mileage to obtain a first ratio, and determining the first ratio as the fourth aging rate, and the first reference mileage is the longest mileage allowed to be driven by the vehicle after the air conditioner filter is replaced each time; or calculating the ratio between the cumulative mileage of the vehicle when the air conditioner filter is used after the last time the air conditioner filter is replaced and the second reference mileage to obtain a second ratio, and determining the second ratio as the fourth aging rate, and the second reference mileage is the longest mileage allowed to be driven by the vehicle when the air conditioner filter is used after the air conditioner filter is replaced each time.

[0119] The cumulative mileage of the vehicle after the last time the air conditioner filter is replaced and the cumulative mileage of the vehicle when the air conditioner filter is used after the last time the air conditioner filter is replaced will be introduced below.

[0120] In a possible implementation, the vehicle controller can access the maintenance record of the vehicle through the database interface of the officially authorized vehicle repair shop, query the mileage of the vehicle after the last time the air conditioner filter is replaced, and then calculate the cumulative mileage of the vehicle after the last time the air conditioner filter is replaced according to the current mileage.

[0121] In a possible implementation, the vehicle controller can extract the time of starting the vehicle air conditioner each time and the corresponding mileage of the vehicle through the log file stored in the internal memory or external storage device of the vehicle, so that when the vehicle air conditioner is turned off again after being turned on each time, the increase in the mileage of the vehicle during the period when the vehicle air conditioner is turned on can be recorded through the air conditioner state sensor, and then the increase in the mileage of the vehicle each time the vehicle air conditioner is started after the last time the air conditioner filter is replaced is accumulated according to the current date and the date of replacing the air conditioner filter, so as to obtain the cumulative mileage of the vehicle when the air conditioner filter is used after the last time the air conditioner filter is replaced.

[0122] After obtaining the cumulative mileage of the vehicle after the last time the air conditioner filter is replaced and the cumulative mileage of the vehicle when the air conditioner filter is used after the last time the air conditioner filter is replaced, the process of determining the fourth aging rate of the air conditioner filter based on the cumulative mileage of the vehicle after the last time the air conditioner filter is replaced will be introduced in detail.

[0123] It should be noted that the vehicle can generally travel a certain distance with the air conditioner filter in a healthy state after replacing the air conditioner filter each time, in other words, the performance of the air conditioner filter will decrease with the increase of the cumulative driving distance after the vehicle replaces the air conditioner filter last time. That is, in one possible implementation, the ratio between the cumulative driving distance after the vehicle replaces the air conditioner filter last time 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] The first reference mileage is the longest mileage allowed to be traveled by the vehicle after replacing the air conditioner filter each time, which is pre-set by the developer according to the service life of the air conditioner filter and saved in the internal memory of the vehicle.

[0125] For example, when the first reference mileage is 10000km and the cumulative driving distance after the vehicle replaces the air conditioner filter last time is 8000km, the ratio between the first reference mileage (8000km) and the cumulative driving distance after the vehicle replaces the air conditioner filter last time (10000km) can be calculated, that is, the first ratio = 8000km / 1000km = 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 ratio of the cumulative driving distance after the vehicle replaces the air conditioner filter last time and the first reference mileage is at most 1, that is, when the cumulative driving distance after the vehicle replaces the air conditioner filter last time is greater than the first reference 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 conditioner filter based on the cumulative driving distance after the vehicle replaces the air conditioner filter last time, the process of determining the fourth aging rate of the air conditioner filter based on the cumulative driving distance when using the air conditioner filter after the vehicle replaces the air conditioner filter last time will be introduced in detail.

[0128] Similarly, the vehicle can generally travel a certain distance with the air conditioner filter in a healthy state after replacing the air conditioner filter each time, in other words, the performance of the air conditioner filter will decrease with the increase of the cumulative driving distance when using the air conditioner filter after the vehicle replaces the air conditioner filter last time, that is, in one possible implementation, the ratio between the cumulative driving distance when using the air conditioner filter after the vehicle replaces the air conditioner filter last time and the second reference mileage can be calculated to obtain a second ratio, and the second ratio is determined as the fourth aging rate.

[0129] The second reference mileage is the longest mileage allowed for the vehicle to travel when using the air conditioner filter after the air conditioner filter is replaced once, which is preset by the developer according to the service life of the air conditioner filter and stored in the internal memory of the vehicle. It should be noted that, since the second reference mileage is the longest mileage allowed for the vehicle to travel when using the air conditioner filter after the air conditioner filter is replaced once, and the first reference mileage is the longest mileage allowed for the vehicle to travel after the air conditioner filter is replaced once, the second reference mileage is less than the first reference mileage. For example, when the first reference mileage is 10,000 km, the second reference mileage can be 5,000 km, 6,000 km, or 7,000 km, etc., which is not limited by the embodiments of the present application.

[0130] For example, when the second reference mileage can be 5,000 km, and the cumulative mileage of the vehicle when using the air conditioner filter after the air conditioner filter is replaced once is 4,000 km, the ratio between the second reference mileage (5,000 km) and the cumulative mileage of the vehicle when using the air conditioner filter after the air conditioner filter is replaced once (4,000 km) can be calculated, i.e. the second ratio = 4,000 km / 5,000 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 ratio between the cumulative mileage of the vehicle when using the air conditioner filter after the air conditioner filter is replaced once and the second reference mileage is also at most 1, i.e. when the cumulative mileage of the vehicle when using the air conditioner filter after the air conditioner filter is replaced once is greater than the second reference mileage, the maximum value of the fourth aging rate is 1.

[0132] The third part is to sum the first aging rate, the second aging rate, the third aging rate and the fourth aging rate to obtain the target aging rate.

[0133] For example, 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, i.e. 0.4+0.3+0.5+0.8 = 2, and the sum (2) after addition is determined as the target aging rate.

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

[0135] Step (1), sum the third aging rate and the fourth aging rate to obtain the sixth aging rate of the air conditioner filter, and the sixth aging rate is used to represent the influence of the service life data of the air conditioner filter on the performance of the air conditioner filter.

[0136] For example, 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) can be added, that is, 0.5+0.8=1.3, and the sum (1.3) is determined as the sixth aging rate.

[0137] In step (2), the first aging rate, the second aging rate, and the sixth aging rate are multiplied by the respective preset weights to obtain the adjusted first aging rate, the adjusted second aging rate, and the adjusted sixth aging rate.

[0138] It should be noted that after obtaining the sixth aging rate for indicating the influence of the use cycle data of the air conditioner filter element on the performance of the air conditioner filter element, it is considered that the first aging rate, the second aging rate, and the sixth aging rate have different influences on the performance of the air conditioner filter element. Therefore, 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 are respectively multiplied by the respective preset weights to obtain the adjusted first aging rate, the adjusted second aging rate, and the adjusted sixth aging rate. Thus, the target aging rate is obtained based on the adjusted first aging rate, the adjusted second aging rate, and the adjusted sixth aging rate.

[0139] For example, the first aging rate is assigned a first weight, the second aging rate is assigned a second weight, and the sixth aging rate is assigned a third weight. 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-mounted air conditioner can directly reflect the performance of the air conditioner filter element, and the health status data of the vehicle-mounted air conditioner is not affected by the official maintenance record, the first aging rate obtained based on the health status data of the vehicle-mounted air conditioner can be assigned the highest weight among the three weights, that is, the first weight is greater than the second weight and the third weight.

[0141] In addition, since the obtained use cycle data of the air conditioner filter element (i.e., the use time of the air conditioner filter element and the driving mileage of the vehicle) is affected by the non-official maintenance record, that is, there is a large deviation between the obtained use cycle data of the air conditioner filter element and the actual use cycle data of the air conditioner filter element. Therefore, in order to reduce the influence of the deviation on determining the timing of prompting the user to replace the air conditioner filter element as much as possible, in the embodiments of the present application, the sixth aging rate obtained based on the use cycle data of the air conditioner filter element can be assigned the lowest weight among 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-mounted air conditioner cannot directly reflect the performance of the air conditioner filter element, but the working data of the vehicle-mounted air conditioner is not affected by the official maintenance record, the second aging rate obtained based on the working data of the vehicle-mounted air conditioner can be given a second weight greater than the third weight and less than the first weight.

[0143] For example, the first weight given to the first aging rate is 0.7, the second weight given to the second aging rate is 0.2, and the first weight given to the sixth aging rate is 0.1.

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

[0145] For example, 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 can be obtained as 0.4*0.7=0.28, the adjusted second aging rate can be obtained as 0.3*0.2=0.06, and the adjusted sixth aging rate can be obtained as 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, i.e. the target aging rate=0.28+0.06+0.13=0.47.

[0146] Step 203, in the case where the target aging rate of the air conditioner filter element is greater than the first aging threshold, outputting the prompt information for replacing the air conditioner filter element.

[0147] 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 by the embodiments of the present application.

[0148] The prompt information for replacing the air conditioner filter element can be text or voice, etc. For example, the prompt information can be the text "please replace the air conditioner filter element" or "the performance of the air conditioner filter element is poor, please replace the air conditioner filter element" displayed on the vehicle central electronic screen, etc., which is not limited by the embodiments of the present application.

[0149] For example, when the first aging threshold is 0.6 and the target aging rate of the air conditioner filter element is determined to be 0.66, since the target aging rate (0.66) is greater than the first aging threshold (0.6), i.e. in this case, the vehicle control unit will control the vehicle central electronic screen to output the prompt information for replacing the air conditioner filter element.

[0150] In summary, the reminding method of the air conditioner provided in the application can determine the target aging rate of the air conditioner filter element by obtaining the running state data of the vehicle-mounted air conditioner and the use cycle data of the air conditioner filter element of the vehicle-mounted air conditioner, and output the prompt information for replacing the air conditioner filter element when the target aging rate of the air conditioner filter element is greater than the first aging threshold. Since the target aging rate of the air conditioner filter element is determined by the running state data of the vehicle-mounted air conditioner and the use cycle data of the air conditioner filter element, and the running state data of the vehicle-mounted air conditioner is not affected by the official maintenance record, the accuracy of the target aging rate of the air conditioner filter element can be improved in the case that there is a large deviation between the obtained use cycle data of the air conditioner filter element and the actual use cycle data, i.e., in the case that the user replaces the air conditioner filter element through a vehicle maintenance shop that is not officially authorized, so that the accuracy of the timing for reminding the user to replace the air conditioner filter element can be improved, and resource waste caused by the air conditioner filter element being replaced too early and the influence on the air quality in the vehicle caused by the air conditioner filter element being replaced too late can be avoided.

[0151] In view of the fact that the target aging rate determined at the time when the air conditioner filter element is just replaced cannot timely reflect the performance of the air conditioner filter element, in a possible implementation manner, the prompt information for replacing the air conditioner filter element can not be output in the case that the state value of the air conditioner filter element is the second flag bit (1), i.e., in the case that the air conditioner filter element is normal and the target aging rate of the air conditioner filter element is greater than the second aging threshold. Since the air conditioner filter element is normal, it indicates that the air conditioner filter element is just replaced, and the target aging rate determined at this time cannot timely reflect the performance of the air conditioner filter element, so in this case, the prompt information for replacing the air conditioner filter element can not be output, so as to avoid resource waste caused by the air conditioner filter element being replaced too early. The second aging threshold is a threshold greater than the first aging threshold, which is set in advance by the developer according to experimental data and stored in the internal storage of the vehicle, for example, when the first threshold is 0.6, the second aging threshold can be 0.7, 0.8 or 0.85, etc., which is not limited in the embodiments of the application. In the case that the state value of the air conditioner filter element is the first flag bit (0), i.e., in the case that the air conditioner filter element is abnormal and the target aging rate of the air conditioner filter element is greater than the first aging threshold, it indicates that the air conditioner filter element is not replaced, and the performance of the air conditioner filter element is very poor at this time, i.e., in this case, the prompt information for replacing the air conditioner filter element needs to be output to remind the user to replace the air conditioner filter element, so as to avoid the influence on the air quality in the vehicle caused by the air conditioner filter element being replaced too late.
