[0051] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0052] refer to Figure 1 A schematic diagram of the structure of a supercharged engine intake system is shown, and Figure 2 The schematic diagram of the structure of a naturally aspirated engine intake system is shown. Both the supercharged engine intake system and the naturally aspirated engine intake system include an air filter. A filter element is provided in the air filter. The side of the air filter close to the intake pipe is the intake side of the air filter, and the side of the air filter close to the outlet pipe is the outlet side of the air filter.

[0053] The filter element is used to block dust and impurities in the air to obtain clean air. To ensure the effective isolation of the filter element, the filter element should be replaced according to a certain replacement cycle. In a suitable environment, the replacement cycle of the filter element can be determined according to the conventional vehicle maintenance standards, and the replacement cycle in a suitable environment is usually longer.

[0054] However, in harsh environments such as deserts or high-temperature sandstorms, the service life of the filter element may be drastically shortened, rendering conventional maintenance standards invalid, and making it impossible to clearly determine the replacement cycle of the filter element, and as a result, it will be impossible to replace the filter element in time when the filter element fails.

[0055] Based on this, in order to solve the problem of how to replace the filter element in time, the present application proposes a filter element maintenance reminder method, system, storage medium and vehicle, which determines whether the vehicle is in the target environment through the vehicle's positioning information. When the vehicle is in the target environment, the first filter element maintenance reminder information is output based on the ambient temperature of the vehicle's air filter and the particle diameter and / or dust concentration on the air filter outlet side. When the filter element is working, if it is outside the appropriate operating temperature range, the filtering capacity of the filter element will be greatly reduced. At the same time, if the filtering capacity of the filter element is reduced, the particle diameter and dust concentration on the air filter outlet side will increase significantly. Therefore, it is possible to determine whether the filter element is in a normal working state through the ambient temperature and dust information, and then when it is determined that the filter element is in an abnormal working state, the driver can receive the first filter element maintenance reminder information in time, so as to replace the filter element in time. Specifically including:

[0056] The first aspect of the present application proposes an embodiment, such as Figure 3 As shown in the step diagram of a filter element maintenance reminder method, the method is applied to a vehicle controller, and the main steps include:

[0057] Step S101, based on the positioning information of the vehicle, determining whether the vehicle is in a target environment.

[0058] The positioning information can be the latitude and longitude coordinates of the vehicle, which can be obtained through the GPS (Global Positioning System) system installed on the vehicle, the Beidou positioning system, or a mobile device that is connected to the vehicle and has a positioning function. The target environment refers to an environment with high dust or sand content in the air, such as sandstorms, or deserts and Gobi areas.

[0059] In an optional implementation, if the target environment is sandstorm weather, the weather information of the vehicle's current location can be obtained from the weather detection system according to the vehicle's positioning information, and based on the obtained weather information, it is determined whether the vehicle is in the target environment. If the target environment is a desert or Gobi area, the positioning information can be compared with the range of the desert or Gobi predetermined in the map, and it can be determined whether the vehicle is currently in the range of the desert or Gobi according to the positioning information to determine whether the vehicle is in the target environment.

[0060] Step S102, when the vehicle is in the target environment, obtaining the ambient temperature around the air filter of the vehicle and the dust information on the outlet side of the air filter, wherein the dust information includes particle diameter and / or dust concentration.

[0061] Take the target environments of dusty weather and desert Gobi as examples. When the target environment is dusty weather, if the weather information obtained from the weather detection system indicates that the weather at the current location of the vehicle is dusty weather, then the vehicle is determined to be in the target environment; when the target environment is desert Gobi, if the positioning information indicates that the current location of the vehicle is within the range of the desert Gobi, then the vehicle is determined to be in the target environment.

[0062] When the vehicle is in the target environment, it indicates that the filter element is in a harsh environment where the service life may be drastically shortened. At this time, it is necessary to monitor various parameters of the filter element to determine whether the filter element is currently in normal working condition.

[0063] During the production process, in order to ensure that the air entering the engine combustion chamber has been filtered, a circle of sealant needs to be applied to the edge of the filter element to prevent air leakage. Therefore, in order to ensure the effectiveness of the filter element's filtering function, the sealant should be in an effective state. Based on this, combined with the factors that affect the state of the sealant, it can be seen that when the ambient temperature of the air filter is higher than the melting point of the sealant, the sealant will melt and then fail. Therefore, when the vehicle is in the target environment, the state of the sealant can be determined by the ambient temperature of the air filter, and then based on the state of the sealant, it can be determined whether the filter element is currently in normal working conditions.

[0064] In an optional embodiment, since the ambient temperature around the air filter has a direct impact on the housing temperature of the air filter housing and the air temperature inside the air filter, the housing temperature and the air temperature can accurately reflect the ambient temperature around the air filter. Based on this, when obtaining the ambient temperature around the air filter, a temperature sensor can be installed on the lower housing of the air filter or inside the air filter, and the ambient temperature around the air filter can be determined by measuring the housing temperature of the air filter or the air temperature inside the air filter through the temperature sensor.

[0065] At the same time, if the filter element is damaged and the filtering effect is reduced, the particle diameter on the outlet side of the air filter will greatly increase, and the dust concentration will also greatly increase. Therefore, when the vehicle is in the target environment, the particle diameter and dust concentration on the outlet side of the air filter can also be used to determine whether the filter element is currently in normal working conditions.

[0066] In summary, when the vehicle is in the target environment, the ambient temperature of the air filter and the dust information on the outlet side of the air filter should be obtained.

[0067] Step S103: outputting first filter element maintenance reminder information based on the ambient temperature and / or the dust information.

[0068] After obtaining the ambient temperature and dust information, the first filter element maintenance reminder information can be output based on the ambient temperature, or based on the dust information, or based on the ambient temperature and dust particles.

[0069] In an optional embodiment, the first filter element maintenance reminder information can be output when the ambient temperature is within a preset range, or when the dust information meets the preset conditions, or when the ambient temperature is within a preset range and the dust information meets the preset conditions.

[0070] Considering that when the ambient temperature is within a preset range, or when the dust information meets the preset conditions, or when the ambient temperature is within a preset range and the dust information meets the preset conditions, the filter element may be in an irreparable damaged state, therefore, the first filter element maintenance reminder information may be a reminder information to remind the driver to replace the filter element. Specifically, the first filter element maintenance reminder information may be transmitted to the driver in the form of voice through the voice assistant on the vehicle, or displayed in the form of image text on the vehicle's central control screen or instrument screen.

[0071] The present application determines whether the vehicle is in the target environment through the positioning information of the vehicle. When the vehicle is in the target environment, the first filter element maintenance reminder information is output based on the ambient temperature of the vehicle air filter and the particle diameter and / or dust concentration on the air filter outlet side. When the filter element is working, if it is outside the suitable working temperature range, the filtering capacity of the filter element will be greatly reduced. At the same time, if the filtering capacity of the filter element is reduced, the particle diameter and dust concentration on the air filter outlet side will be greatly increased. Therefore, it is possible to determine whether the filter element is in a normal working state through the ambient temperature and dust information, and then when it is determined that the filter element is in an abnormal working state, the driver will receive the first filter element maintenance reminder information in time, so as to replace the filter element in time.

[0072] In another embodiment of the present application, in addition to the steps in the above-mentioned embodiment, the following steps are also included:

[0073] Alternatively, if Figure 4 As shown in the step diagram of a filter element maintenance reminder method for controlling the vehicle speed, after step S103, the method further includes:

[0074] Step S104: determining a speed threshold of the vehicle in the target environment based on the ambient temperature and / or the dust information.

[0075] When the vehicle controller outputs the first filter element maintenance information, it indicates that the filter element is actually damaged or about to be damaged. At this time, if the vehicle is still traveling at a high speed, the air flow velocity in the intake duct and the force of the air flow on the filter element will be at a high level to meet the air demand of the vehicle at high speed, thereby aggravating the damage of the filter element. Therefore, in order to avoid further deterioration of the damage to the filter element, the driving speed of the vehicle in the target environment should be limited.

[0076] Specifically, the speed threshold of the vehicle in the target environment can be determined by the ambient temperature, or by the dust information, or by the ambient temperature and the dust information. For example, since the higher the ambient temperature, the worse the adhesiveness of the sealant, the speed threshold should decrease with the increase of the ambient temperature. Or, since the greater the deviation between the dust information and the preset conditions, the worse the filtering effect of the filter element, and further inferring that the damaged area of ​​the filter element may be larger, the speed threshold should decrease with the increase of the deviation between the dust information and the preset conditions. Or, considering the influence weights of the ambient temperature and the dust information on the speed threshold, the speed threshold is determined by combining the two.

[0077] Step S105, controlling the vehicle's running speed to be less than the speed threshold to reduce the load on the engine.

[0078] After determining the speed threshold, a control signal carrying the speed threshold is sent to the engine controller, and the engine controller controls the engine speed to be below the speed threshold corresponding to the speed threshold, so that the vehicle's driving speed is maintained at a state less than the speed threshold, thereby reducing the load on the vehicle engine. For example, based on the ambient temperature and / or the dust information, if the speed threshold is determined to be 30 km / h, the vehicle's driving speed is controlled below 30 km / h until the driver completes the filter element replacement or the vehicle leaves the target environment.

[0079] Alternatively, if Figure 5 As shown in the step diagram of a filter element maintenance reminder method based on mileage, when the vehicle is in a target environment, the method includes:

[0080] Step S201, obtaining the mileage of the vehicle in the target environment.

[0081] Since the target environment is a dusty weather or desert Gobi environment with high dust or sand content in the air, even if the filter element is not damaged, it still needs to be replaced or cleaned after the vehicle has traveled a long distance. Based on this, when the vehicle is in the target environment, it is also necessary to determine whether maintenance measures are needed for the filter element based on the mileage of the vehicle in the target environment, so as to comprehensively and comprehensively consider the factors affecting the maintenance of the filter element and ensure the driving safety of the vehicle in the target environment to the greatest extent.

[0082] When the mileage is less than the mileage threshold, the process proceeds to step S202 ; when the mileage is greater than or equal to the mileage threshold, the process proceeds to step S203 .

[0083] Step S202, when the mileage is less than the mileage threshold, periodically execute the step of obtaining the ambient temperature around the air filter of the vehicle and the dust information on the outlet side of the air filter, wherein the dust information includes particle diameter and / or dust concentration; and outputting the first filter element maintenance reminder information based on the ambient temperature and / or the dust information.

[0084] Because when the vehicle mileage is less than the mileage threshold, the filter element is still in good condition and within its service life, so when the mileage is less than the mileage threshold, the only situation where maintenance measures need to be taken for the filter element is when the filter element is damaged. In other words, when the mileage is less than the mileage threshold, it is only necessary to monitor whether the filter element is damaged. Among them, the mileage threshold can be determined based on the remaining service life of the filter element. The longer the remaining service life, the greater the mileage threshold; the shorter the remaining service life, the smaller the mileage threshold.

[0085] Based on this, when the vehicle mileage is less than the mileage threshold, the steps of "obtaining the ambient temperature around the air filter of the vehicle and the dust information on the outlet side of the air filter, wherein the dust information includes particle diameter and / or dust concentration; based on the ambient temperature and / or the dust information, outputting the first filter element maintenance reminder information" can be periodically executed, which are steps S102 and S103 in the embodiment provided by the first aspect of the present invention.

[0086] At this time, considering that the filter element has been damaged or is about to be damaged, the first filter element maintenance reminder information can be a reminder information to remind the driver to replace the filter element.

[0087] In an optional embodiment, the above-mentioned cycle can be determined as 1 hour, that is, the step of "obtaining the ambient temperature around the air filter of the vehicle and the dust information on the outlet side of the air filter, the dust information including particle diameter and / or dust concentration; based on the ambient temperature and / or the dust information, outputting the first filter element maintenance reminder information" is performed once every 1 hour.

[0088] Step S203, when the mileage is greater than or equal to the mileage threshold, directly outputting the second filter element maintenance reminder information.

[0089] When the mileage is greater than or equal to the mileage threshold, since the vehicle has traveled a long distance in a harsh environment and the filter element is nearing the end of its service life, maintenance measures should be taken regardless of whether the filter element is damaged. Based on this, when the mileage is greater than or equal to the mileage threshold, the second filter element maintenance reminder information should be directly output.

[0090] At this time, considering that the filter element is not damaged, the second maintenance reminder information can be a reminder information for prompting the driver to replace or clean the filter element. Specifically, the second filter element maintenance reminder information can be transmitted to the driver in the form of voice through the voice assistant on the vehicle, or displayed in the form of image text on the vehicle's central control screen or instrument screen.

[0091] Alternatively, if Figure 6 As shown in the step diagram of a filter element maintenance reminder method based on the filter element brand, the step S103 outputs the first filter element maintenance reminder information based on the ambient temperature and / or the dust information, including:

[0092] Step S1031, obtaining the brand of the filter element.

[0093] The brand of the filter element actually represents the manufacturer of the filter element. The brand of the filter element can be used to know the production standard and quality of the filter element, which has a great impact on the conditions that lead to filter element damage. Generally speaking, larger manufacturers have stricter control over the production process and higher standards for manufacturing raw materials, so the quality of the filter elements they produce is better. Based on this, the quality of the filter element can be determined by the brand of the filter element, and the conditions that lead to filter element damage can be determined based on the quality of the filter element.

[0094] Step S1032: determining a temperature threshold of the ambient temperature based on the brand.

[0095] In actual use, there is a temperature limit. When the ambient temperature is below the temperature limit, the probability of filter element damage is small. When the ambient temperature is above the temperature limit, the probability of filter element damage increases greatly. Therefore, the temperature limit at which the filter element is prone to damage can be determined as the temperature threshold of the ambient temperature.

[0096] Step S1033, when the ambient temperature is greater than the temperature threshold and / or the dust information does not meet the preset conditions, output the first filter element maintenance reminder information, wherein the preset conditions are that the particle diameter is greater than the diameter threshold and / or the dust concentration is greater than the concentration threshold.

[0097] After determining the temperature threshold of the ambient temperature, the first filter element maintenance reminder information can be output when the ambient temperature is greater than the temperature threshold, or when the dust information does not meet the preset conditions, or when the ambient temperature is greater than the temperature threshold and the dust information does not meet the preset conditions.

[0098] By determining the temperature threshold of the ambient temperature through the brand of the filter element, the timing of outputting the first filter element maintenance reminder information can be determined based on the conditions of different filter elements, thereby realizing a flexible reminder strategy based on specific analysis of specific situations and improving the refinement of the filter element maintenance reminder.

[0099] Optionally, determining the temperature threshold of the ambient temperature based on the brand in step S1031 includes: scanning a brand logo configured for the filter element to obtain the brand to which the filter element belongs; wherein the brand logo includes at least one of a barcode and a QR code.

[0100] The filter element is provided with a brand logo consisting of a barcode or a QR code. By scanning the brand logo with a camera, the brand of the filter element can be directly obtained, thereby reducing the steps of manually inputting the filter element brand and realizing the automation of filter element brand acquisition. At the same time, the influence of human factors is reduced in the process of obtaining the filter element brand, and the accuracy of filter element brand acquisition is improved.

[0101] Optionally, the brand of the filter element includes a certified brand and a non-certified brand. The temperature threshold of the ambient temperature is determined based on the brand in step S1032, including two cases, as follows:

[0102] A certified brand refers to a manufacturer that is certified as a qualified supplier by the vehicle's OEM; a non-certified brand refers to a manufacturer that is not certified as a qualified supplier by the vehicle's OEM. Generally speaking, the production standards of certified brand filter elements are more stringent and the manufacturing materials are more excellent, so the heat resistance is better than that of non-certified brand filter elements. For example, based on the melting points of sealants used in multiple filter elements on the market, the melting point of sealants used in certified brand filter elements is usually 120°C, while the melting point of sealants used in non-certified brands is usually 80°C, so the sealants used by certified brands are better than those used by non-certified brands.

[0103] In case one, when the brand of the filter element is a certified brand, the temperature threshold is determined to be the first temperature threshold.

[0104] Case 2: when the brand of the filter element is a non-certified brand, the temperature threshold is determined to be the second temperature threshold; wherein the first temperature threshold is greater than the second temperature threshold.

[0105] In the above cases 1 and 2, when the brand of the filter element is a certified brand, the temperature threshold is the first temperature threshold, and when the brand of the filter element is a non-certified brand, the temperature threshold is the second temperature threshold. Since the certified brand filter element has better heat resistance, the first temperature threshold should be greater than the second temperature threshold. For example, since the sealant of the certified brand filter element begins to fail at 120°C and the filter element begins to be damaged, the sealant of the non-certified brand filter element begins to fail at 80°C and the filter element begins to be damaged, the heat resistance of the certified brand filter element is better than that of the non-certified brand filter element. At this time, 120°C can be determined as the first temperature threshold, and 80°C can be determined as the second temperature threshold. Obviously, 120°C is greater than 80°C, so the first temperature threshold is greater than the second temperature threshold.

[0106] This embodiment adopts different filter element maintenance reminder strategies for filter elements of certified brands and filter elements of non-certified brands, thereby achieving flexible reminders based on specific analysis of specific situations and improving the refinement of filter element maintenance reminders.

[0107] Alternatively, if Figure 7 As shown in the step diagram of a method for outputting first filter element maintenance prompt information, the outputting first filter element maintenance prompt information in step S103 includes:

[0108] Step S1034, obtaining the pressure difference between the air inlet side of the filter element and the air outlet side of the filter element.

[0109] The air inlet side of the filter element is the side of the filter element close to the air inlet pipe, and the air outlet side of the filter element is the side of the filter element close to the air outlet pipe. When the air containing dust and other impurities flows from the air inlet side of the filter element to the air outlet side of the filter element, the dust and other impurities are blocked by the filter element and remain on the air inlet side of the filter element, and the clean air flows out from the air outlet side of the filter element. At this time, the surface pressure of the air inlet side of the filter element is greater than the surface pressure of the air inlet side of the filter element due to the effect of the dust and air flowing through, thereby generating a pressure difference between the air inlet side and the air outlet side of the filter element.

[0110] During normal use, the pressure difference between the air inlet and air outlet of the filter element will increase with the increase of usage time. If the filter element is suddenly damaged, a large amount of air on the air inlet side will flow from the damaged part to the air outlet side, thereby reducing the surface pressure on the air inlet side and reducing the pressure difference between the air inlet and air outlet sides. Therefore, when outputting the first filter element maintenance reminder information, the pressure difference between the air inlet and air outlet sides can be taken into consideration.

[0111] Step S1035, determining the risk level of the filter element based on the air pressure difference.

[0112] Since the larger the damaged area of ​​the filter element, the more air will flow from the damaged area to the outlet side, the smaller the surface pressure on the inlet side of the filter element, and the smaller the pressure difference between the inlet side and the outlet side of the filter element, the damaged area of ​​the filter element can be determined by the pressure difference, and different risk levels can be defined based on different damaged areas. For example, when the damaged area of ​​the filter element is smaller than the first area, the risk level is determined as low risk; when the damaged area of ​​the filter element is greater than or equal to the first area and smaller than the second area, the risk level is determined as medium risk; when the damaged area of ​​the filter element is greater than or equal to the second area, the risk level is determined as high risk, where the first area is smaller than the second area.

[0113] Step S1036, outputting the first filter element maintenance reminder information corresponding to the risk level.

[0114] After determining the risk level of the filter element, output the first filter element maintenance reminder information corresponding to the risk level. For example, when the risk level is a low risk level, the first filter element maintenance reminder information with voice or image text "The filter element is damaged, the current damaged area is smaller than the first area, the risk level is a low risk level, please replace the filter element in time" can be output. When the risk level is a medium risk level, the first filter element maintenance reminder information with voice or image text "The filter element is damaged, the current damaged area is greater than or equal to the first area and smaller than the second area, the risk level is a medium risk level, please replace the filter element in time" can be output. When the risk level is a high risk level, the first filter element maintenance reminder information with voice or image text "The filter element is damaged, the current damaged area is greater than or equal to the second area, the risk level is a high risk level, please replace the filter element in time" can be output.

[0115] Based on the pressure difference between the air inlet side and the air outlet side, the risk level of the filter element is divided, and the first filter element maintenance prompt information corresponding to the risk level is output, which can improve the driver's understanding of the current status of the filter element, and make it easier for the driver to take flexible maintenance measures based on the current status of the filter element.

[0116] The third aspect of the present application proposes an embodiment, such as Figure 8 As shown in the flowchart of a filter element maintenance reminder method, the method includes:

[0117] Based on the vehicle's positioning information, determine whether the vehicle is in the target environment; when the vehicle is in the target environment, obtain the vehicle's mileage in the target environment.

[0118] When the mileage is less than the mileage threshold, the ambient temperature around the air filter of the vehicle and the dust information on the outlet side of the air filter are periodically obtained; the brand of the filter element is obtained; when the brand of the filter element is a certified brand, the temperature threshold is determined to be a first temperature threshold; when the brand of the filter element is a non-certified brand, the temperature threshold is determined to be a second temperature threshold; wherein the first temperature threshold is greater than the second temperature threshold; when the ambient temperature is greater than the temperature threshold and / or the dust information does not meet the preset conditions, the first filter element maintenance prompt information is output, wherein the preset conditions are that the particle diameter is greater than the diameter threshold and / or the dust concentration is greater than the concentration threshold; and the step of controlling the vehicle's driving speed.

[0119] The step of obtaining the brand of the filter element includes: scanning the brand logo configured for the filter element to obtain the brand of the filter element; wherein the brand logo includes at least one of a barcode and a QR code. The step of outputting the first filter element maintenance reminder information includes: obtaining the pressure difference between the air inlet side of the filter element and the air outlet side of the filter element; based on the pressure difference, determining the risk level of the filter element; and outputting the first filter element maintenance reminder information corresponding to the risk level. The step of controlling the vehicle's driving speed includes: determining the speed threshold of the vehicle in the target environment based on the ambient temperature and / or dust information; controlling the vehicle's driving speed to be less than the speed threshold to reduce the load on the engine.

[0120] When the mileage is greater than or equal to the mileage threshold, the second filter element maintenance reminder information is directly output.

[0121] In addition, reference Fig. 9 A structural schematic diagram of a vehicle filter element maintenance reminder device is shown, and Fig.10 The following is a situation enumeration diagram of a filter element maintenance reminder method, taking a specific application scenario as an example to illustrate the filter element maintenance reminder system described in this application:

[0122] like Fig. 9As shown, a dust sensor is installed on the upper shell of the air filter, and a temperature sensor is installed on the lower shell, which are used to collect the ambient temperature of the air filter and the dust information on the air outlet side of the air filter when the vehicle is in the target environment.

[0123] After collecting the ambient temperature and dust information, the two are sent to the vehicle controller, and the vehicle controller provides filter maintenance reminders based on the two.

[0125] If the filter element maintenance reminder is performed through method one, then when the filter element brand is a certified brand, the first filter element maintenance reminder information is output when the ambient temperature is greater than 120°C and the particle diameter is greater than 20um; when the filter element brand is a non-certified brand, the first filter element maintenance reminder information is output when the ambient temperature is greater than 80°C and the particle diameter is greater than 20um.

[0126] If the filter element maintenance reminder is performed through method 2, when the mileage is less than the mileage threshold, if the filter element brand is a certified brand, the ambient temperature is greater than 120°C, and the particle diameter is greater than 20um, the first filter element maintenance reminder information is output; if the filter element brand is a non-certified brand, the ambient temperature is greater than 80°C, and the particle diameter is greater than 20um, the first filter element maintenance reminder information is output. When the mileage is greater than or equal to the mileage threshold, the second maintenance reminder information is output.

[0127] The fourth aspect of the present application proposes an embodiment, such as Fig.11 As shown in the structural schematic diagram of a filter element maintenance reminder system, the system includes:

[0128] A judgment module, used to determine whether the vehicle is in a target environment based on the positioning information of the vehicle;

[0129] an acquisition module, configured to acquire, when the vehicle is in the target environment, an ambient temperature around an air filter of the vehicle and dust information on an outlet side of the air filter, wherein the dust information includes a particle diameter and / or a dust concentration;

[0130] The first execution module is used to output first filter element maintenance reminder information based on the ambient temperature and / or the dust information.

[0131] Optionally, the system also includes a speed regulation module, which is used to determine a speed threshold of the vehicle in the target environment based on the ambient temperature and / or the dust information; and control the driving speed of the vehicle to be less than the speed threshold to reduce the load on the engine.

[0132] Optionally, the system also includes a second execution module, which is used to obtain the mileage of the vehicle in the target environment; when the mileage is less than a mileage threshold, periodically execute the step of obtaining the ambient temperature around the air filter of the vehicle and the dust information on the outlet side of the air filter, wherein the dust information includes particle diameter and / or dust concentration; based on the ambient temperature and / or the dust information, outputting first filter element maintenance reminder information; when the mileage is greater than or equal to the mileage threshold, directly outputting second filter element maintenance reminder information.

[0133] Optionally, the first execution module is also used to obtain the brand of the filter element; based on the brand, determine the temperature threshold of the ambient temperature; when the ambient temperature is greater than the temperature threshold and / or the dust information does not meet the preset conditions, output the first filter element maintenance reminder information, wherein the preset conditions are that the particle diameter is greater than the diameter threshold and / or the dust concentration is greater than the concentration threshold.

[0134] Optionally, the first execution module is further used to scan the brand logo configured for the filter element to obtain the brand to which the filter element belongs; wherein the brand logo includes at least one of a barcode and a QR code.

[0135] Optionally, the first execution module is also used to determine that the temperature threshold is a first temperature threshold when the brand of the filter element is a certified brand; when the brand of the filter element is a non-certified brand, determine that the temperature threshold is a second temperature threshold; wherein the first temperature threshold is greater than the second temperature threshold.

[0138] An embodiment of the present application also provides a vehicle, including a filter element maintenance reminder system provided by the present application, or including a control module, wherein the control module is used to implement the steps of the filter element maintenance reminder method described in the embodiment of the present application.

[0139] The present application determines whether the vehicle is in the target environment through the positioning information of the vehicle. When the vehicle is in the target environment, the first filter element maintenance reminder information is output based on the ambient temperature of the vehicle air filter and the particle diameter and / or dust concentration on the air filter outlet side. When the filter element is working, if it is outside the suitable working temperature range, the filtering capacity of the filter element will be greatly reduced. At the same time, if the filtering capacity of the filter element is reduced, the particle diameter and dust concentration on the air filter outlet side will be greatly increased. Therefore, it is possible to determine whether the filter element is in a normal working state through the ambient temperature and dust information, and then when it is determined that the filter element is in an abnormal working state, the driver will receive the first filter element maintenance reminder information in time, so as to replace the filter element in time.
