Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The air conditioner filter element of the vehicle is used for filtering the air sucked by the vehicle and has a filtering function. The filter can effectively filter and absorb pollen, dust, peculiar smell and the like, thereby ensuring the good air in the vehicle. However, the air conditioner filter element has certain dust holding capacity and absorption limit value, and the filtering efficiency of the air conditioner filter element is reduced in real time while the air conditioner filter element filters the substances. When the temperature is reduced to a certain limit value, the filter element can not play the necessary role. The untimely replacement of the vehicle air conditioner filter element can cause the pollution of the filter element to the sucked air, and certain harm is brought to passengers in the vehicle. And if the filter core just changes too early when the quality is good, will improve customer's vehicle use cost, also bring inconvenience to customer's use of vehicle. The remaining life of the vehicle air conditioning filter is therefore usually monitored.

Accordingly, an embodiment of the present invention provides a method for detecting a state of an air conditioner filter element, and referring to fig. 1, fig. 1 is a schematic flow diagram of a first embodiment of the method for detecting a state of an air conditioner filter element according to the present application. In this embodiment, the execution subject in the embodiment shown in fig. 1 may be a vehicle (specifically, may be a controller of the vehicle), or may be a cloud server, or the vehicle may implement the processing procedure steps in the embodiment shown in fig. 1 together with the user mobile terminal with the cloud server. The cloud server can be an intelligent networking server so as to run various algorithms by virtue of the advantages of mass data resources of the intelligent networking server; the user mobile terminal includes, but is not limited to, a smart phone, a desktop computer, a tablet computer, a notebook computer, a digital assistant, a smart wearable device, and the like, and may also include software running in the physical device, such as an Application APP (Application), a web page, a wechat applet, and the like, and may also include a vehicle-mounted system in a vehicle, which is not limited herein.

step S10, when a vehicle air conditioner starting signal is detected, acquiring a current filter element service life value of an air conditioner filter element, and acquiring air conditioner operation parameters of a vehicle;

in this embodiment, the air conditioner operation parameters include air conditioner operation mode information, air conditioner operation gear information, and air quality information outside the vehicle. The air quality information outside the vehicle can be detected by an air quality sensor mounted on the vehicle. The kind of the air quality sensor may include a PM2.5 concentration sensor, a carbon dioxide concentration sensor, a carbon monoxide concentration sensor, and the like, and the present embodiment is not particularly limited.

In some embodiments, the operation mode information of the vehicle air conditioner may include that the vehicle air conditioner is in an inside air circulation mode or an outside air circulation mode. The air conditioner operation gear information may include a gear in which the air conditioner wind is located, for example, 1, 2, 3, or 4. The off-board air quality information may include concentration data of particulate matter of a specific diameter in the air, such as concentration data of fine particulate matter PM 2.5. The air quality data can be acquired through a sensing detection device installed outside the vehicle, and also can be acquired from the air quality data issued by a professional organization through the communication between the vehicle and a network terminal.

Step S20, counting the air conditioner operation accumulated time corresponding to the air conditioner operation parameters, and determining a filter element service life loss value of the air conditioner filter element according to the air conditioner operation parameters and the air conditioner operation accumulated time;

in this embodiment, because the air flow through the air conditioner filter element is different under different air conditioner operation gears, and the larger the air flow through the air conditioner filter element is, the greater the deposition rate of dust and impurities in the air on the air conditioner filter element is in the process of filtering the air by the air conditioner filter element, and the faster the filter element life loss rate of the air conditioner filter element is. Therefore, in the embodiment, the current filter element life loss value of the air conditioner filter element is judged by taking the air conditioner running gear information of the vehicle air conditioner as one of the air conditioner running parameters and combining the corresponding air conditioner running accumulated time of the vehicle air conditioner under the air conditioner running parameters, so that the reliability of identifying the use state of the air conditioner filter element is improved.

In addition, it is easy to understand that, because the quality of the air outside the vehicle is poorer, that is, the concentration of particulate matters with specific diameters in the air is higher, the deposition rate of dust and impurities in the air deposited on the air conditioning filter element is higher in the process of filtering the air by the air conditioning filter element, and the service life loss rate of the air conditioning filter element is also higher. Therefore, the present embodiment determines the current filter element life loss value of the air conditioner filter element by using the air quality information outside the air conditioner as one of the air conditioner operation parameters and combining the air conditioner operation accumulated time corresponding to the air conditioner operation parameters of the vehicle, thereby being beneficial to more scientifically and accurately identifying the use state of the air conditioner filter element.

In the present embodiment, the air impurities such as dust and pollen in the air outside the vehicle tend to be more than the air inside the vehicle, that is, the air quality outside the vehicle tends to be worse than the air quality inside the vehicle. Therefore, when the vehicle air conditioner is in the outside air circulation mode, dust and foreign materials in the air are more easily deposited on the air conditioner filter element than in the inside air circulation mode. That is, the air conditioning filter element in the outside air circulation mode has a faster rate of filter element life loss than in the inside air circulation mode. Therefore, in the embodiment, the service life loss value of the current filter element of the air conditioner filter element is judged by taking the running mode information of the vehicle air conditioner as one of the air conditioner running parameters and combining the corresponding air conditioner running accumulated time of the vehicle air conditioner under the air conditioner running parameters, so that the accuracy of identifying the current use state of the air conditioner filter element is improved.

In this embodiment, it should be noted that one air conditioner operation parameter corresponds to an accumulated air conditioner operation time period, and the accumulated air conditioner operation time period is in a continuous accumulated state when none of the air conditioner operation mode information, the air conditioner operation gear information, and the outside air quality information is changed, that is, when the air conditioner operation parameter of the vehicle is not changed. And if the current air-conditioning operation parameter A of the vehicle is changed into the air-conditioning operation parameter B, accumulating the accumulated air-conditioning operation time length of the air-conditioning operation parameter B at the moment.

To facilitate understanding of the present application that "one air conditioner operation parameter corresponds to one air conditioner operation accumulated time period", an example is listed, for example, 10, 30, 09 in 2022: 30-2022 year 10, month 30, day 12: and (3) 30 operating air conditioner operating parameters A, wherein the air conditioner operating mode information is an external air circulation mode, the air conditioner operating gear information is 3-gear, and the air quality information outside the vehicle is good. During this time, the air-conditioning operation cumulative time period of the air-conditioning operation parameter a is cumulative, and if in 2022, 10, 30, 09:30 air-conditioning operation parameter a, the cumulative time period of air-conditioning operation is 0, then in 2022, 10 months, 30 days 12: the air-conditioning operation cumulative time period of the 30 air-conditioning operation parameter a has been accumulated for 3 hours. And 12 at 30/10/2022: 30-2022 year 10 month 30 day 15:00, 10, 30, 12 in 2022: 30-2022 year 10 month 30 day 15:00 operating air conditioner operating parameter B: the air conditioner operation mode information is an external air circulation mode, the air conditioner operation gear information is 2 gears, the external air quality information is good, and if 12 in 10 months, 30 days in 2022: 30 air-conditioning operation parameter a, the cumulative time period of air-conditioning operation is 0, then in 2022, 10 months, 30 days 15: the cumulative time period for air conditioning operation of 00 has accumulated for two and a half hours. Next, 10 months, 30 days, 15 in 2022: 10 month, 30 day, 00 to 2022 16: and the air-conditioning operation parameters of the 30 vehicles are changed into air-conditioning operation parameters A, wherein the air-conditioning operation mode information is an external air circulation mode, the air-conditioning operation gear information is 3 gears, and the air quality information outside the vehicles is good, and at the moment, the air-conditioning operation parameters A are continuously accumulated on the basis of 3 hours accumulated before, namely 16 in 10 months and 30 days in 2022: and 30, accumulating the air conditioner operation accumulated time length corresponding to the air conditioner operation parameter A to 4 half hours.

It will be appreciated by those skilled in the art that each air conditioning operating parameter is required to correspond to a cumulative length of air conditioning operation since different air conditioning operating parameters will tend to correspond to different rates of filter element life loss. Illustratively, the service life of the filter element at the current life calculated at 21/11/2022 is 212t (the accumulated air conditioner operation time corresponding to all kinds of air conditioner operation parameters is reset at 22/11/2022), where the life loss rate corresponding to the air conditioner operation parameter a is 3 t/hr, the life loss rate corresponding to the air conditioner operation parameter B is 2 t/hr, and the life loss rate corresponding to the air conditioner operation parameter C is 5 t/hr, where the accumulated air conditioner operation time corresponding to the air conditioner operation parameter a counted at 22/11/2022/11/1 day is 5 hours, the accumulated air conditioner operation time corresponding to the air conditioner operation parameter B is 3 hours, and the accumulated air conditioner operation time corresponding to the air conditioner operation parameter C is 1 hour, then the service life loss value of the filter element at the current time is obtained: 5 + 3+ 2+1 + 5=26t, at this time, according to the filter element life loss value, updating the current filter element service life value, and obtaining a latest current filter element service life value as: 212t-26t =186t. It is easy to understand that if the service life value of the current filter element is 0t, the filter element of the air conditioner needs to be replaced.

And S30, dynamically updating the current filter element service life value according to the filter element service life loss value to obtain the latest current filter element service life value.

In this embodiment, the filter element life loss value may be subtracted from the current filter element life value to obtain the latest current filter element life value. It is easy to understand that the latest current filter element service life value at different moments is obtained by subtracting the current filter element service life loss value from the current filter element service life value at different moments, so that the dynamic update of the current filter element service life value is realized.

At present, whether an air conditioner filter element of an automobile needs to be replaced is generally judged according to driving mileage or driving duration, but for different automobile types, driving environments and air conditioner using habits, the using states of the air conditioner filter element in the automobile are different, the replacing time of the air conditioner filter element is also judged according to the actual condition of each automobile, in addition, the mounting position of the air conditioner filter element is hidden, the disassembly operation is inconvenient, an automobile owner basically cannot actively check the air conditioner filter element, the air conditioner filter element is generally checked by a 4S shop during large maintenance, the overuse of a plurality of filter elements is caused, the pollution degree of air in the automobile is increased, harm is brought to the health of the automobile owner, the air conditioner refrigerating effect is reduced, the wind power of an air outlet is insufficient, and the like; for some vehicles which are used less or have clean use environments, the air conditioner filter element is replaced when the state is good, and certain waste of resources and cost is caused. Therefore, there is a need to provide a more efficient solution.

And in this embodiment, when a vehicle air conditioner start signal is detected, the current filter element service life value of the air conditioner filter element is acquired, and the air conditioner operation parameter of the vehicle is acquired, wherein the air conditioner operation parameter includes air conditioner operation mode information, air conditioner operation gear information and vehicle exterior air quality information, then the air conditioner operation accumulated time corresponding to the air conditioner operation parameter is counted, and according to the air conditioner operation parameter and the air conditioner operation accumulated time, the filter element service life loss value of the air conditioner filter element is determined, and then according to the filter element service life loss value, the current filter element service life value is dynamically updated, the latest current filter element service life value is obtained, so that the current remaining service life of the vehicle air conditioner filter element can be accurately analyzed, the data reference for replacing the air conditioner filter element is provided, the resource waste caused by replacing the filter element in advance is avoided, meanwhile, the excessive use of the air conditioner filter element caused by late replacement can be avoided, the filtering effect cannot be achieved or the peculiar smell is generated, and the driving experience of a vehicle user is improved.

Compared with the prior art that whether the filter element needs to be replaced is judged according to the vehicle driving mileage and the vehicle service time, the practical driving environment of the vehicle (namely the air conditioner operation condition of the vehicle) is analyzed by collecting air conditioner operation parameters such as air conditioner operation mode information, air conditioner operation gear information, air quality information outside the vehicle and the like according to the embodiment, and further according to the air conditioner operation condition of the vehicle and the accumulated time of the air conditioner operation under the air conditioner operation condition, so that the filtering and purifying capacity of the air conditioner filter element in the current state is accurately detected, whether the service life value of the current filter element of the air conditioner filter element reaches the lower limit is objectively and scientifically judged, the replacement time of the air conditioner filter element of the vehicle is timely and accurately determined, the air purifying effect in the vehicle is ensured, the respiratory health problem of a driver is greatly reduced, the accuracy of identifying the current use state of the air conditioner filter element of the vehicle is improved, and the technical problem of low accuracy of identifying the current use state of the air conditioner filter element of the vehicle is solved.

In order to further improve the accuracy of the current service state of the air conditioner filter element of the vehicle, the user is reminded to replace the air conditioner filter element more timely and accurately. In one possible embodiment, the air conditioner operation parameters further include current ambient temperature information, air humidity information, current location information, and the like of the vehicle.

In the present embodiment, the current ambient temperature information of the vehicle can be detected by a temperature sensor mounted on the vehicle. As known to those skilled in the art, a filtering layer of an air conditioning filter element is often added with a certain amount of highly effective adsorbing materials such as activated carbon and the like to achieve a better filtering effect. The current ambient temperature of the vehicle often affects the adsorption performance of the high efficiency adsorption material in the filter layer, for example, the adsorption performance of the high efficiency adsorption material is often low at low temperature. Therefore, under the higher air conditioner operating condition of ambient temperature, the higher the rate that the high efficiency adsorption material in the filter layer reaches saturation is, that is to say, the higher the consumption rate of the high efficiency adsorption material in the filter layer is, thereby the faster the life-span loss rate of the air conditioner filter element is. Therefore, the present embodiment determines the current filter element life loss value of the air conditioner filter element by using the ambient temperature information of the vehicle air conditioner as one of the air conditioner operation parameters, and combines the corresponding air conditioner operation accumulated duration of the vehicle air conditioner under the air conditioner operation parameters, thereby improving the accuracy of identifying the use state of the air conditioner filter element.

For example, the current air humidity information of the vehicle may be detected by a humidity sensor mounted on the vehicle. Because vehicle air conditioner is when the operation, air humidity is higher, and highly effective adsorption material such as active carbon in this filter layer is influenced by the vapor in the air more easily and is produced rotten, consequently, under the higher air conditioner operating condition of air humidity, the rate that highly effective adsorption material in the filter layer produced rotten is faster, and the high-efficient adsorption material in the filter layer consumes the rate that also is faster to make air conditioner filter element's life-span loss rate faster. Therefore, in the embodiment, the current filter element service life loss value of the air conditioner filter element is judged by taking the air humidity information of the vehicle air conditioner as one of the air conditioner operation parameters, and the corresponding air conditioner operation accumulated duration of the vehicle air conditioner under the air conditioner operation parameters is combined, so that the reliability of identifying the use state of the air conditioner filter element is improved.

In this embodiment, the current position information of the vehicle may be obtained through a Global Positioning System (GPS) mounted on the vehicle, and it is easily understood that since the vehicle is located at different driving positions, and the external air quality information, the ambient temperature information, and the air humidity information of the current time period of the area corresponding to the different driving positions are different, the current position information of the vehicle may be obtained, the current area of the vehicle may be determined according to the current position information, and then the external air quality information, the ambient temperature information, and the air humidity information of the current time period of the area may be obtained through a network. Specifically, the outside air quality information, the environment temperature information and the air humidity information of the current time period of the area can be obtained from an environment climate big data platform or an internet of vehicles communication platform (the internet of vehicles communication platform is an intelligent internet server) through a network, so that the outside air quality information, the environment temperature information and the air humidity information can be accurately obtained in real time and are used as partial factors in air conditioner operation parameters, the current filter element life loss value of the air conditioner filter element is judged by combining the corresponding air conditioner operation accumulated time of the vehicle air conditioner under the air conditioner operation parameters, and the accuracy of identifying the use state of the air conditioner filter element is improved.

The embodiment also collects the current environment temperature information, the air humidity information and the current position information of the vehicle on the basis of collecting the air conditioner running mode information, the air conditioner running gear information and the air quality information outside the vehicle, thereby fully combining more relevant influence factors influencing the loss rate of the air conditioner filter element, comprehensively considering the influence of the air conditioner running parameters such as the environment temperature information, the air humidity information, the current position information, the air conditioner running mode information, the air conditioner running gear information and the air quality information outside the vehicle on the loss rate of the air conditioner filter element, combining the corresponding air conditioner running accumulated duration of the vehicle air conditioner under the air conditioner running parameters, further obtaining a more real filter element life loss value, and further improving the identification accuracy of the use state of the air conditioner filter element.

In a possible embodiment, the step of dynamically updating the current filter element service life value according to the filter element service life loss value to obtain a latest current filter element service life value includes:

step A10, determining the best date information for replacing the air conditioner filter element according to the latest current filter element service life value;

and step A20, outputting the optimal date information.

In this embodiment, the best date information of replacing the air conditioner filter element can be displayed on a central control display screen of the vehicle, or the best date information of replacing the air conditioner filter element can be played through a loudspeaker carried by the vehicle in a voice broadcasting mode, so that the purpose of outputting the best date information is achieved. Of course, the best date information for replacing the air conditioner filter element can be sent to a mobile terminal of a user in a short message mode, for example, a mobile phone of the user, so that the purpose of outputting the best date information is achieved.

In the embodiment, the optimal date information for replacing the air conditioner filter element is determined according to the latest current service life value of the filter element, and the optimal date information is output, so that a user can conveniently master the current use condition of the air conditioner filter element in real time to be used as a parameter for evaluating whether the vehicle air conditioner filter element needs to be replaced or not,

further, as an example, after the step of determining optimal date information for replacing an air conditioner filter element, the method further comprises:

step B10, acquiring current date information;

and step B20, if the difference value between the current date information and the optimal date information is smaller than a preset threshold value, outputting prompt information that the air conditioner filter element needs to be replaced.

In this embodiment, correspondingly, the accessible shows the suggestion information that the air conditioner filter core of will exporting needs to be changed in the well accuse display screen of vehicle, perhaps plays the suggestion information that this output air conditioner filter core needs to be changed through the speaker that the vehicle carried through voice broadcast's mode, reaches the purpose of exporting this suggestion information. The prompt message that the air conditioner filter element needs to be replaced can be sent to a mobile terminal of a user in a short message mode, for example, a mobile phone of the user, so that the aim of outputting the prompt message can be fulfilled.

In the embodiment, by acquiring the current date information, if the difference value between the current date information and the optimal date information is smaller than the preset threshold value, the prompt information that the air conditioner filter element needs to be replaced is output, so that the user is prompted to replace the air conditioner filter element timely and accurately.

In one practical implementation, after the step of outputting the prompt that the air conditioner filter element needs to be replaced, the method further includes:

and step C20, if the vehicle is detected to replace the air conditioner filter element, obtaining filter element object information of the replaced air conditioner filter element, and resetting the service life value of the current filter element of the air conditioner filter element according to the filter element object information.

In this embodiment, it should be noted that the filter element object information may include one or more of a filter element model of the air conditioner filter element, a filter element manufacturer, a filter element brand, a maximum allowable dust holding capacity of the filter element, and a service life of the filter element.

Therefore, the maximum allowable dust holding capacity of the filter element of the replaced air conditioner filter element can be determined according to one or more of the model of the filter element of the air conditioner filter element, the manufacturer of the filter element and the brand of the filter element. It can be understood that the maximum allowable dust holding capacity of the filter element is related to the service life of the filter element, that is, the larger the maximum allowable dust holding capacity of the filter element of the air conditioner filter element is, the longer the service life of the filter element is.

In a possible implementation manner, please refer to fig. 2, and fig. 2 is a flowchart illustrating a method for detecting a state of an air conditioner filter element according to a second embodiment of the present invention. The step of determining the filter element service life loss value of the air conditioner filter element according to the air conditioner operation parameters and the accumulated air conditioner operation duration comprises the following steps:

step S40, according to the air conditioner operation parameters, the air conditioner filter element loss coefficients corresponding to the air conditioner operation parameters are obtained through query from a preset loss coefficient mapping table;

and S50, determining a filter element service life loss value of the air conditioner filter element according to the air conditioner filter element loss coefficient and the accumulated air conditioner operation time length.

As an example, in step S50, the step of determining the filter element life loss value of the air conditioner filter element according to the air conditioner filter element loss coefficient and the accumulated air conditioner operation time period includes:

d10, constructing a filter element service life loss prediction model according to the air conditioner filter element loss coefficient;

and D20, inputting the air conditioner operation accumulated time into the constructed filter element life loss prediction model, and predicting to obtain a filter element life loss value of the air conditioner filter element.

It should be noted that the model function corresponding to the filter element life loss prediction model can be used to represent the life loss rate of the filter element at the air conditioner operation parameter a, so that the accumulated air conditioner operation duration corresponding to the air conditioner operation parameter a can be input to the constructed filter element life loss prediction model, and the filter element life loss value of the air conditioner filter element can be predicted.

To facilitate understanding, an example is given, in which the model function corresponding to the filter element life loss prediction model represents that the life loss rate of the filter element at the air conditioner operation parameter a is 2 t/h, and the accumulated air conditioner operation time length corresponding to the air conditioner operation parameter a of the current statistical period (one statistical period may be one day, or one week, without limitation) is: and 6 hours, inputting the parameters into the constructed filter element life loss prediction model, and predicting the filter element life loss value of the air conditioner filter element as follows: 2 × 6=12t.

In this embodiment, the loss coefficient mapping table stores a mapping relationship between an air conditioner operation parameter and an air conditioner filter element loss coefficient, and since a vehicle air conditioner operates under different air conditioner operation parameters, the service life loss rates of the air conditioner filter elements are often different, and the air conditioner filter element loss coefficient reflects or represents the service life loss rate of the air conditioner filter element, the air conditioner operation parameter is associated with the air conditioner filter element loss coefficient. Therefore, the loss coefficient mapping table can be calibrated by testing the vehicle through various set air conditioner operating conditions before leaving the factory, and is prestored in a memory of the vehicle or prestored in an intelligent network server. Specifically, the vehicle air conditioner can be operated under different air conditioner operation conditions, air conditioner operation parameters under different air conditioner operation conditions are collected, then the service life loss rate of the air conditioner filter element mapped by the different air conditioner operation parameters is recorded, and different air conditioner filter element loss coefficients are set according to the mapped service life loss rate of the air conditioner filter element, so that the pre-calibration of the loss coefficient mapping table is completed.

Step S70, if the number of the information samples of the prompt accuracy evaluation information is larger than a preset number threshold, correcting the loss coefficient mapping table according to the prompt accuracy evaluation information to obtain a corrected loss coefficient mapping table;

as can be understood by those skilled in the art, the greater the number of information samples of the prompt accuracy evaluation information, the more accurately the accuracy of the current filter element service life value calculated by the present embodiment can be reflected, and the more accurately the prompt information prompting that the air conditioner filter element needs to be replaced in the present embodiment can be reflected.

According to the embodiment, the step of correcting the loss coefficient mapping table according to the prompt accuracy evaluation information is executed only when the number of the information samples of the prompt accuracy evaluation information is larger than the preset number threshold, so that the condition that the loss coefficient of the air conditioner filter element mapped by the current air conditioner operation parameter of the vehicle cannot be accurately inquired according to the loss coefficient mapping table due to the fact that the number of the samples of the prompt accuracy evaluation information is too small and whether the loss coefficient mapping table calibrated by preselection is accurate or not can be objectively and accurately reflected is avoided.

In step S40, the step of obtaining the air conditioner filter element loss coefficient corresponding to the air conditioner operation parameter by querying from a preset loss coefficient mapping table includes:

and E10, inquiring the loss coefficient of the air conditioner filter element corresponding to the air conditioner operation parameter from the corrected loss coefficient mapping table.

In the embodiment, the prompt accuracy evaluation information generated by evaluating the accuracy of the prompt information is acquired, and if the number of information samples of the prompt accuracy evaluation information is greater than the preset number threshold, the loss coefficient mapping table is corrected according to the prompt accuracy evaluation information to obtain the corrected loss coefficient mapping table, so that the loss coefficient mapping table is dynamically corrected through the prompt accuracy evaluation record of the replacement of the air conditioner filter element by a user, the prediction precision of the filter element life loss value by the filter element life loss prediction model is rolled and improved, and the accuracy of identifying the current use state of the air conditioner filter element of the vehicle is continuously improved.
