With the increase in the use frequency of automobiles, the use frequency of the on-vehicle air conditioner is also increasing. However, after the on-vehicle air conditioner has been used for a long time, a lot of dust will accumulate on the air-conditioning filter screen of the on-vehicle air conditioner. Since the air-conditioning filter screen is generally located near the air-conditioning evaporator, affected by the humid environment near the air-conditioning evaporator, the dust accumulated on the air-conditioning filter screen will breed bacteria and even mildew over time, and will be blown into the vehicle through the air conditioner, seriously affecting the health of automobile users.

[0052] Those skilled in the art can understand that Figure 1 the structure shown in

Figure 1 shown, the memory 1005, as a storage medium, may include an operating system, a network communication module, a user interface module, and an air conditioner filter state detection program.

The air conditioner filter state detection device calls the air conditioner filter state detection program stored in the memory 1005 through the processor 1001 and executes the air conditioner filter state detection method provided by the embodiment of the present invention.

[0055] An embodiment of the present invention provides an air conditioner filter state detection method. Refer to Figure 2 , Figure 2 which is a schematic flowchart of the first embodiment of an air conditioner filter state detection method of the present invention.

[0056] In this embodiment, the air conditioner filter state detection method includes the following steps:

[0057] Step S10: Detect the air quality of the current driving environment of the vehicle to be detected to obtain an environmental air detection result.

[0058] It should be noted that when this embodiment is applied to detecting the state of the air conditioner filter of the on-vehicle air conditioner on the vehicle to be detected, the air quality of the current driving environment of the vehicle to be detected is detected to obtain an environmental air detection result, the air quality of the vehicle cockpit of the vehicle to be detected is detected to obtain a cockpit air detection result, and the air conditioner filter state of the vehicle to be detected is determined based on the environmental air detection result and the cockpit air detection result.

[0059] Compared with the prior art that cannot effectively detect the state of the air conditioner filter, in this embodiment, by separately detecting the air quality of the current driving environment and the vehicle cockpit, the air quality of the current operating environment of the on-vehicle air conditioner of the vehicle to be detected is accurately determined, and then the air conditioner filter state of the vehicle to be detected is determined based on the environmental air detection result and the cockpit air detection result, realizing accurate detection of the air conditioner filter state, enabling the user to clean the air conditioner filter in time, ensuring the user's physical health, and effectively improving the user experience.

[0060] It should be understood that the execution subject of the method in this embodiment can be an air conditioner filter state detection device with data processing, network communication, and program running functions, such as an on-vehicle controller, or other devices or equipment that can achieve the same or similar functions. Here, the above-mentioned air conditioner filter state detection device (hereinafter referred to as the filter detection device) is used as an example for description.

[0061] It should be noted that the vehicle to be detected can be a vehicle that needs to detect the state of the air conditioner filter on the on-vehicle air conditioner. The above-mentioned current driving environment can be the environment where the vehicle to be detected is currently located, and the air quality of the above-mentioned current driving environment can be the air quality of the environment where the vehicle to be detected is currently located. For example, the air quality of the current driving environment can be the air particle concentration quality, temperature quality, and humidity quality of the current driving environment, etc.

[0062] It should be understood that due to different environmental factors in different environments, in order to accurately detect the air quality of the current driving environment of the vehicle to be tested, the filter detection device in this embodiment obtains the current geographical location information of the vehicle to be tested, queries the current weather information corresponding to the current geographical location information through a preset weather query server, determines the relative humidity, current wind speed, current temperature and current particulate matter concentration of the current driving environment according to the current weather information, and detects the air quality of the current driving environment of the vehicle to be tested according to the above relative humidity, current wind speed, current temperature and current particulate matter concentration, and obtains the environmental air detection result.

[0063] Step S20: Detect the air quality of the vehicle cockpit of the vehicle to be tested to obtain the cockpit air detection result.

[0064] It should be noted that the vehicle cockpit can be the in-vehicle cockpit of the vehicle to be tested, and the air quality of the above vehicle cockpit can be the in-vehicle air quality of the vehicle to be tested. The air quality of the above vehicle cockpit can be the quality of the particulate matter concentration in the vehicle. When the air filter of the vehicle-mounted air conditioner is too dusty, it will cause the particulate matter concentration in the vehicle cockpit to rise, thus reducing the air quality of the vehicle cockpit. Therefore, the filter detection device can determine the current state of the air filter by detecting the air quality of the vehicle cockpit.

[0065] It should be understood that since too much dust accumulation on the air filter of the vehicle-mounted air conditioner will cause the particulate matter concentration in the vehicle cockpit to rise, in order to accurately detect the state of the air filter, the filter detection device in this embodiment detects the air quality of the vehicle cockpit of the vehicle to be tested according to the particulate matter concentration by obtaining the particulate matter concentration in the vehicle cockpit, and obtains the cockpit air detection result.

[0066] Step S30: Determine the air filter state of the vehicle to be tested based on the environmental air detection result and the cockpit air detection result.

[0067] It should be noted that the air filter state can be the current health state or usage state of the air filter of the vehicle-mounted air conditioner on the vehicle to be tested, that is, the current degree of dirtiness of the air filter. The filter detection device can judge whether it is necessary to remind the user to clean the air filter of the vehicle-mounted air conditioner by detecting the air filter state of the vehicle to be tested.

[0068] It should be understood that in order to accurately detect the state of the air-conditioning filter, the filter detection device in this embodiment obtains the current usage state of the vehicle-mounted air conditioner, where the current usage state includes the duration of the internal circulation operation, the duration of the external circulation operation, the duration of the blower operation, and the current air volume gear. The particulate matter concentration in the current driving environment and the particulate matter concentration in the vehicle cabin are obtained, and the particulate matter concentration in the current driving environment is compared with the particulate matter concentration in the vehicle cabin. According to the comparison result, the correction value of the particulate matter is determined. Referring to the following formula 1, formula 1 is the degree of dirtiness of the air-conditioning filter (i.e., the state of the air-conditioning filter), where Δa is the internal circulation calibration coefficient, Δb is the external circulation calibration coefficient, Δc is the blower calibration coefficient, nx is the duration of the internal circulation operation, wx is the duration of the external circulation operation, gf is the duration of the blower operation, fd is the air volume gear, Δf is the particulate matter concentration calibration coefficient, pme is the correction value obtained after comparing the particulate matter concentration in the current driving environment with the particulate matter concentration in the vehicle cabin, Δe is the weather correction coefficient, and WX is the temperature and humidity information of the current driving environment.

[0069] E = (Δa * nx + Δb * wx + Δc * gf * fd) + Δf * pme + Δe * WX Formula 1

[0070] In a specific implementation, the filter detection device determines the state of the air-conditioning filter of the vehicle to be detected based on the environmental air detection result and the cabin air detection result, determines the degree of dirtiness of the air-conditioning filter according to the state of the air-conditioning filter, and judges whether the degree of dirtiness of the air-conditioning filter exceeds the preset standard according to the preset conditions. If it needs to exceed the standard, a cleaning reminder message is generated according to the state of the air-conditioning filter, and the user is reminded to clean the air-conditioning filter based on the cleaning reminder message; if it does not exceed the standard, the state of the air-conditioning filter is continuously monitored.

[0071] Further, in order to timely remind the user to replace the air-conditioning filter, step S30 above may include:

[0072] Calibrate the dirtiness state of the vehicle-mounted air conditioner of the vehicle to be detected according to the air-conditioning filter state detection result, and obtain the current dirtiness parameter of the vehicle-mounted air conditioner;

[0073] Judge whether the current dirtiness parameter exceeds the preset threshold;

[0074] If so, generate a reminder message according to the current dirtiness parameter, and perform an air-conditioning filter replacement reminder based on the reminder message.

[0075] It should be noted that the dirtiness state can be the current dirtiness degree calibration state of the air-conditioning filter of the vehicle-mounted air conditioner by the filter detection device. The above current dirtiness parameter can be the parameter obtained by the filter detection device after calibrating the dirtiness degree of the vehicle-mounted air conditioner based on the dirtiness state. For example, the current dirtiness parameter can be a percentage parameter.

[0076] In this embodiment, the air quality of the current driving environment of the vehicle to be detected is detected to obtain an ambient air detection result, the air quality of the vehicle cabin of the vehicle to be detected is detected to obtain a cabin air detection result, and the air-conditioning filter state of the vehicle to be detected is determined based on the ambient air detection result and the cabin air detection result; since the present invention detects the air quality of the current driving environment and the vehicle cabin respectively, thereby accurately determining the air quality of the current operating environment of the on-vehicle air conditioner of the vehicle to be detected, and then determining the air-conditioning filter state of the vehicle to be detected based on the ambient air detection result and the cabin air detection result, it realizes accurate detection of the air-conditioning filter state, enabling the user to clean the air-conditioning filter in a timely manner, ensuring the user's physical health, and effectively improving the user experience.

[0077] Reference Figure 3 , Figure 3 is a schematic flowchart of the second embodiment of a method for detecting the air-conditioning filter state of the present invention.

[0078] Based on the above first embodiment, in this embodiment, the step S20 includes:

[0079] Step S201: Obtain the air-conditioning operation information of the vehicle to be detected.

[0080] It should be noted that the air-conditioning operation information may be information related to the current operating state of the on-vehicle air conditioner of the vehicle to be detected. For example, the air-conditioning operation information may include the working duration and working state of the circulation system of the on-vehicle air conditioner, the working duration and working state of the blower, and the current air volume output of the on-vehicle air conditioner. The above circulation system may include the internal circulation system and the external circulation system of the on-vehicle air conditioner.

[0081] Furthermore, in order to accurately determine the operating state of the on-vehicle air conditioner, the above step S201 may include:

[0082] Step S2011: Obtain the current circulation duration of the circulation system of the on-vehicle air conditioner of the vehicle to be detected;

[0083] Step S2012: Obtain the current working duration and current air volume information of the blower of the on-vehicle air conditioner;

[0084] Step S2013: Determine the air-conditioning operation information of the vehicle to be detected according to the current circulation duration, the current working duration, and the current air volume information.

[0085] It should be noted that the current cycle duration can be the current working duration of the circulation system of the vehicle-mounted air conditioner, where the above-mentioned circulation system can include the external circulation system and the internal circulation system of the vehicle-mounted air conditioner, that is, the current cycle duration can include the external circulation duration and the internal circulation duration. The above-mentioned current air volume information can be the current air output volume information and the current air volume gear information of the vehicle-mounted air conditioner.

[0086] Further, in order to accurately calibrate the various operating parameters of the vehicle-mounted air conditioner to accurately obtain the air conditioner operating information, the above-mentioned step S2013 may include:

[0087] Obtain the current geographical information of the vehicle to be detected;

[0088] Determine the circulation calibration coefficient of the circulation system and the air blowing calibration coefficient of the blower according to the current geographical information;

[0089] Calibrate the current cycle duration based on the circulation calibration coefficient to obtain a circulation calibration result;

[0090] Calibrate the current working duration and the current air volume information respectively based on the air blowing calibration coefficient to obtain an air blowing calibration result;

[0091] Determine the air conditioner operating information of the vehicle to be detected according to the circulation calibration result and the air blowing calibration result.

[0092] It should be noted that in order to accurately calibrate the various air conditioner operating parameters to accurately obtain the air conditioner operating information, the filter detection device in this embodiment obtains the current geographical information of the vehicle to be detected, and determines the vehicle to be tested in different regions or locations with different temperatures according to the current geographical location information, such as North China and Northeast China in winter, South China in summer, Central China in spring and autumn, etc. According to the differences in regions, the calibration coefficient corresponding to each operating parameter of the vehicle-mounted air conditioner is determined, and parameter calibration is carried out according to the calibration coefficient. The above-mentioned various operating parameters may include: the external circulation duration, the internal circulation duration, the working duration of the blower, and the current air volume information of the vehicle-mounted air conditioner, etc.

[0093] Step S202: Obtain the environmental particulate matter information of the current driving environment of the vehicle to be detected, and the cabin particulate matter information of the vehicle cabin of the vehicle to be detected.

[0094] It should be noted that the environmental particulate matter information can be information such as the type and concentration of particulate matter in the current driving environment of the vehicle to be detected. For example, the environmental particulate matter information may include information such as the PM2.5 concentration in the current driving environment. The above-mentioned cabin particulate matter information can be information such as the type and concentration of particulate matter in the vehicle cabin of the vehicle to be detected. For example, the cabin particulate matter information may include information such as the PM2.5 concentration in the vehicle cabin.

[0095] Step S203: Compare the environmental particulate matter information and the cabin particulate matter information, and perform particulate matter information calibration based on the comparison result to obtain target particulate matter information.

[0096] It should be noted that the target particulate matter information can be the comprehensive particulate matter information after comparing the environmental particulate matter information and the cabin particulate matter information, or the larger value after comparing the environmental particulate matter information and the cabin particulate matter information.

[0097] It should be understood that in order to accurately determine the particulate matter information in the current operating environment of the vehicle air conditioner, the filter detection device in this embodiment compares the environmental particulate matter information and the cabin particulate matter information, determines the larger value between the environmental particulate matter information and the cabin particulate matter information according to the comparison result, performs particulate matter information calibration based on the larger value, and uses the calibrated particulate matter information as the target particulate matter information.

[0098] Step S204: Detect the air quality of the vehicle cabin according to the target particulate matter information and the air conditioner operation information to obtain a cabin air detection result.

[0099] It should be noted that the cabin air detection result can be the air quality detection result in the vehicle cabin of the vehicle to be detected. The filter detection device can determine the operating state of the vehicle air conditioner according to the cabin air detection result, and then judge whether the filter state is healthy according to the health degree of the operating state. Refer to the following formula 2, where the formula 2 is the health degree value of the vehicle air conditioner. Here, D is the health degree value of the vehicle air conditioner, Δa is the internal circulation calibration coefficient, Δb is the external circulation calibration coefficient, Δc is the blower calibration coefficient, n is the internal circulation working duration, w is the external circulation working duration, g is the blower working duration, and f is the air volume gear.

[0100] D = Δa * n + Δb * w + Δc * g * f Formula 2

[0101] In this embodiment, by obtaining the air-conditioning operation information of the vehicle to be detected, the environmental particulate matter information of the current driving environment of the vehicle to be detected, and the particulate matter information of the vehicle cockpit of the vehicle to be detected, comparing the environmental particulate matter information and the particulate matter information of the cockpit, and calibrating the particulate matter information based on the comparison result to obtain target particulate matter information, detecting the air quality of the vehicle cockpit according to the target particulate matter information and the air-conditioning operation information to obtain a cockpit air detection result; since the present invention compares the environmental particulate matter information and the particulate matter information of the cockpit, calibrates the particulate matter information according to the comparison result, and obtains the target particulate matter information after comprehensive calibration, thereby accurately obtaining the particulate matter concentration in the current operating environment of the on-vehicle air conditioner, detecting the air quality of the vehicle cockpit according to the target particulate matter information and the air-conditioning operation information, and obtaining a cockpit air detection result, thus realizing accurate detection of the air quality of the vehicle cockpit and ensuring the accuracy of the cockpit air detection result.

[0102] Reference Figure 4 , Figure 4 is a schematic flowchart of the third embodiment of a method for detecting the state of an air-conditioning filter screen according to the present invention.

[0103] Based on the above first embodiment, in this embodiment, the step S10 includes:

[0104] Step S101: Obtain the current geographical information of the vehicle to be detected and the current weather information corresponding to the current geographical information.

[0105] It should be noted that the current geographical information may be the geographical information of the current location of the vehicle to be detected. For example, the current geographical information may include the current longitude and latitude information, current regional information, and current altitude information of the current location of the vehicle to be detected. The above current weather information may be the weather information of the current location of the vehicle to be detected. The filter screen detection device may query the current weather information corresponding to the current geographical information according to the weather server. For example, according to the current geographical information, it is determined that the vehicle to be detected is currently located in City A, and the weather corresponding to City A is queried from the weather server as a cloudy day with high humidity and low temperature.

[0106] It should be understood that, in order to accurately determine the weather of the current location of the vehicle to be detected, the filter screen detection device in this embodiment obtains the current geographical information of the location of the vehicle to be detected, extracts the current longitude and latitude and the current altitude from the current geographical information, generates a coordinate to be searched according to the current longitude and latitude and the current altitude, determines the city information corresponding to the current location according to the coordinate to be searched, and queries the current weather information corresponding to the above city information according to the weather server.

[0107] Step S102: Determine the target air information of the current driving environment of the vehicle to be detected according to the current geographical information and the current weather information.

[0108] It should be noted that the target air information may be information related to the air quality of the current driving environment of the vehicle to be detected. For example, the target air information may include information such as the concentration of particulate matter, the types of particulate matter, the types of gases, and the gas concentration in the air of the current driving environment.

[0109] It should be understood that, in order to determine the air quality of the current driving environment of the vehicle to be detected, the filter detection device in this embodiment determines the regional information of the current location of the vehicle to be detected according to the current geographical information, determines the climate information of the current location of the vehicle to be detected according to the current weather information, and determines the gas information and particulate matter information in the air of the current driving environment of the vehicle to be detected according to the regional information and the climate information. Among them, the above gas information includes the types and concentrations of various gases contained in the air, and the above particulate matter information includes the types and concentrations of various particulate matters contained in the air.

[0110] Step S103: Detect the air quality of the current driving environment of the vehicle to be detected according to the target air information, and obtain an environmental air detection result.

[0111] It should be noted that, in order to calibrate air information based on different geographical locations, the filter detection device in this embodiment obtains the current geographical information and the current weather information of the vehicle to be detected, determines the climate of the region where the vehicle to be detected is located according to the current geographical information and the current weather information, such as North China and Northeast China in winter, South China in summer, Central China in spring and autumn, etc. According to the differences in regions, the weather correction coefficient is determined to correct the target air information, the current temperature, and the current humidity according to the weather correction coefficient, so as to obtain more accurate air quality parameters. Refer to the following formula 3, which is the calculation formula for air quality parameters, where A is the air quality parameter, Δf is the air information correction coefficient, p is the target air information in the current driving environment, Δe is the weather correction coefficient, and WX is the temperature and humidity information of the current driving environment.

[0112] A = Δf * p + Δe * WX Formula 3

[0113] Further, in order to effectively avoid air information differences caused by environmental and climate differences in different regions, the above step S103 may include:

[0114] S1031: Determine the initial air information of the current driving environment of the vehicle to be detected according to the current geographical information and the current weather information;

[0115] S1032: Determine the air correction coefficient of the current driving environment according to the current geographical information;

[0116] S1033: Correct the initial air information according to the air correction coefficient to obtain the target air information.

[0117] It should be noted that due to the climate differences, longitude and latitude differences, and altitude differences of each geographical location, the air information of each geographical location will be different. In order to effectively avoid the errors caused by geographical location differences, the filter detection device can calibrate the air correction coefficient of each geographical location according to the current geographical information, so as to correct the initial air information of the current driving environment according to the air correction coefficient to obtain more accurate target air information.

[0118] In this embodiment, by obtaining the current geographical information of the vehicle to be detected and the current weather information corresponding to the current geographical information, the target air information of the current driving environment of the vehicle to be detected is determined according to the current geographical information and the current weather information, and the air quality of the current driving environment of the vehicle to be detected is detected according to the target air information to obtain the environmental air detection result; since the present invention determines the target air information of the current driving environment of the vehicle to be detected according to the current geographical information and the current weather information of the location of the vehicle to be detected, and detects the air quality of the current driving environment of the vehicle to be detected according to the target air information to obtain the environmental air detection result, thus realizing the accurate detection of the air quality of the current driving environment and ensuring the accuracy of the environmental air detection result.
