Description

Technical Field

[0001] This invention relates to the field of automotive technology, and in particular to a method, device, vehicle, and storage medium for monitoring the status of automotive air conditioning filters. Background Technology

[0002] Currently, vehicle users have increasingly higher requirements for in-vehicle air quality. Automotive air conditioning filters, widely used in the automotive industry, not only ensure the cleanliness of the vehicle's air conditioning system but also effectively reduce in-vehicle air pollution.

[0003] Air conditioning filters generally have a limited lifespan and need to be replaced when they expire. Otherwise, the filtration and purification effect of the filter will be greatly reduced, and it may even cause secondary pollution. Currently, vehicle users mainly rely on the usage time of the air conditioning filter or the vehicle's mileage to remind themselves to replace it. However, due to differences in temperature, humidity, air quality, and sandstorms in different regions, judging the remaining lifespan of the air conditioning filter based on usage time or mileage is inaccurate and can easily lead to over- or under-use of the filter. These problems urgently need to be addressed. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, the object of the present invention is to provide a method, device, vehicle, and storage medium for monitoring the status of automotive air conditioning filters.

[0005] The present invention proposes a method for monitoring the status of an automotive air conditioning filter, comprising: acquiring the operating parameters of a blower; determining the dirt value of the air conditioning filter based on the operating parameters; and determining the degree of dirtiness of the air conditioning filter based on the dirt value range in which the dirt value falls.

[0006] In addition, the automotive air conditioning filter status monitoring method according to embodiments of the present invention may also have the following additional technical features:

[0007] Further, determining the dirt value of the air conditioning filter element based on the operating parameters includes: determining the operating mode of the car air conditioning and the operating speed of the blower; determining the operating parameter-dirt value relationship curve model corresponding to the operating mode and the operating speed in a curve model database, wherein the curve model database includes multiple operating parameter-dirt value relationship curve models for different operating modes and operating speeds; inputting the operating parameters into the operating parameter-dirt value relationship curve model to obtain the dirt value corresponding to the operating parameters, wherein the operating parameter-dirt value relationship curve model includes a mapping relationship between multiple operating parameters and dirt values ​​corresponding one-to-one with the multiple operating parameters.

[0008] Furthermore, the relationship curve model between operating parameters and dirt values ​​is obtained by curve fitting of multiple sets of one-to-one correspondences between operating parameters and dirt values.

[0009] Furthermore, the automotive air conditioning filter status monitoring method also includes: issuing a reminder message to replace the filter when the degree of dirtiness is greater than a preset degree of dirtiness.

[0010] Furthermore, the automotive air conditioning filter status monitoring method further includes: displaying different icons or text information on the display device according to the different levels of dirt on the air conditioning filter.

[0011] Furthermore, the operating parameters include operating current or operating power.

[0012] According to the embodiment of the present invention, the method for monitoring the condition of an automotive air conditioning filter obtains the operating parameters of the blower, determines the dirt value of the air conditioning filter based on the operating parameters, and determines the degree of dirtiness of the air conditioning filter based on the dirt value range it falls within. Since the operating parameters of the blower can be obtained conveniently and accurately, the accuracy of judging the degree of dirtiness of the automotive air conditioning filter can be improved. This solves the problem of inaccurate monitoring of the condition of the automotive air conditioning filter, which easily leads to overuse or underuse of the automotive air conditioning filter. This ensures that the automotive air conditioning filter is fully utilized, reduces vehicle maintenance costs, and prevents overuse of the air conditioning filter from causing damage to air conditioning components.

[0013] To address the aforementioned problems, this invention also proposes an automotive air conditioning filter status monitoring device, comprising: an acquisition module for acquiring the operating parameters of a blower; a first determination module for determining the dirt value of the air conditioning filter based on the operating parameters; and a second determination module for determining the degree of dirtiness of the air conditioning filter based on the dirt value range in which the dirt value falls.

[0014] In addition, the automotive air conditioning filter status monitoring device according to embodiments of the present invention may also have the following additional technical features:

[0015] Furthermore, the first determining module is also used to: determine the operating mode of the car air conditioner and the operating speed of the blower; determine the operating parameter-dirt value relationship curve model corresponding to the operating mode and the operating speed in the curve model database, wherein the curve model database includes multiple operating parameter-dirt value relationship curve models for different operating modes and operating speeds; input the operating parameter into the pre-calibrated operating parameter-dirt value relationship curve model to obtain the dirt value corresponding to the operating parameter, wherein the operating parameter-dirt value relationship curve model includes multiple operating parameters and a mapping relationship between the dirt values ​​corresponding to the multiple operating parameters.

Since the operating parameters of the blower can be easily and accurately acquired, this solves the problem of inaccurate monitoring of the automotive air conditioning filter status, which can easily lead to overuse or underuse of the filter. This ensures that the air conditioning filter is fully utilized, reduces vehicle maintenance costs, and prevents damage to air conditioning components due to overuse. Furthermore, by displaying different icons or text information on the display device and issuing a filter replacement reminder when the filter is severely dirty, the degree of dirtiness of the air conditioning filter is clearly visible, allowing users to understand the usage status of the air conditioning filter and replace it promptly.

[0017] To address the aforementioned problems, the present invention also proposes a vehicle, comprising: a processor, a memory, and an automotive air conditioning filter status monitoring program stored in the memory and executable on the processor. When the automotive air conditioning filter status monitoring program is executed by the processor, it implements the automotive air conditioning filter status monitoring method as described in any of the above embodiments.

[0018] According to embodiments of the present invention, by acquiring the operating parameters of the blower, the dirt level of the air conditioning filter is determined based on the operating parameters, and the degree of dirtiness of the air conditioning filter is determined based on the dirt level range it falls within. Since the operating parameters of the blower can be easily and accurately acquired, this solves the problem of inaccurate monitoring of the condition of the car's air conditioning filter, which easily leads to overuse or underuse of the filter. This ensures that the air conditioning filter is fully utilized, reduces vehicle maintenance costs, and prevents damage to air conditioning components due to overuse. Furthermore, by displaying different icons or text information on the display device, and issuing a filter replacement reminder when the filter is severely dirty, the degree of dirtiness of the air conditioning filter is clearly visible, allowing users to understand the usage status of the air conditioning filter and replace it promptly.

[0019] To address the aforementioned problems, the present invention also proposes a computer-readable storage medium storing an automotive air conditioning filter status monitoring program. When the automotive air conditioning filter status monitoring program is executed by a processor, it implements the automotive air conditioning filter status monitoring method as described in any of the above embodiments.

Since the operating parameters of the blower can be easily and accurately acquired, this solves the problem of inaccurate monitoring of the automotive air conditioning filter's status, which can easily lead to overuse or underuse of the filter. This ensures that the air conditioning filter is fully utilized, reducing vehicle maintenance costs and preventing damage to air conditioning components due to overuse. Furthermore, by displaying different icons or text information on a display device and issuing a filter replacement reminder when the filter is severely dirty, the degree of dirtiness of the air conditioning filter is clearly visible, allowing users to understand the filter's usage status and replace it promptly.

[0027] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0028] The following is for reference. Figures 1-4 This invention describes a method, apparatus, vehicle, and storage medium for monitoring the status of automotive air conditioning filters according to embodiments of the present invention.

[0029] Example 1

[0030] Figure 1This is a flowchart of a method for monitoring the status of an automotive air conditioning filter according to an embodiment of the present invention. Figure 1 As shown, a method for monitoring the status of an automotive air conditioning filter includes the following steps:

[0031] Step S1: Obtain the operating parameters of the blower.

[0032] In a specific embodiment, when the car's air conditioning is operating, the blower's operating parameters can be obtained through relevant parameter detection circuits or sensor components. It should be noted that obtaining the blower's operating parameters through current detection circuits or sensor components is existing technology, and to avoid redundancy, it will not be elaborated upon here.

[0033] Step S2: Determine the dirt level of the air conditioning filter based on the operating parameters.

[0034] Specifically, under stable voltage, the operating parameters of a blower decrease as ventilation resistance increases. The degree of dirtiness of the air conditioning filter directly affects this resistance; for example, higher filter dirtiness results in greater ventilation resistance, and vice versa. Therefore, the blower's operating parameters change with the dirtiness level of the air conditioning filter. They may be directly proportional (the blower's operating parameters increase with increasing filter dirtiness) or inversely proportional (the blower's operating parameters decrease with increasing filter dirtiness). Under the same operating conditions, such as when the air conditioner's operating mode and the blower's operating setting are identical, the blower's operating voltage is stable, and its operating parameters correspond to the dirtiness level of the air conditioning filter. Therefore, the dirtiness level of the air conditioning filter can be determined based on the blower's operating parameters, thus characterizing the degree of dirtiness of the filter. Since the operating parameters of the blower can be obtained conveniently and accurately, the accuracy and convenience of judging the degree of dirtiness of the car's air conditioning filter can be improved. This solves the problem of inaccurate monitoring of the condition of the car's air conditioning filter, which can easily lead to overuse or underuse of the filter. This ensures that the air conditioning filter is fully utilized, reduces vehicle maintenance costs, and prevents overuse of the filter from damaging air conditioning components.

[0035] Step S3: Determine the degree of dirtiness of the air conditioning filter based on the dirtiness value range it falls within.

[0036] Specifically, the different dirt levels of the air conditioning filter can be divided into multiple dirt value ranges, with each dirt value range corresponding to a different degree of dirt. For example, the dirt value range includes [0, 50%], [50%, 80%], and [80%, 100%]. That is, the dirt value is divided into three ranges based on 50% and 80% dirt values. When the dirt value of the air conditioning filter is in the range [0, 50%], the filter is considered to be not too dirty and can continue to be used for a longer period of time. When the dirt value is in the range [50%, 80%], the filter is considered to be quite dirty and can continue to be used for a shorter period of time. When the dirt value is in the range [80%, 100%], the filter is considered to be severely dirty and needs to be replaced soon. This addresses the problem of inaccurate monitoring of the condition of the car's air conditioning filter, which can easily lead to overuse or underuse of the filter. This ensures that the air conditioning filter is used fully, reduces vehicle maintenance costs, and prevents damage to air conditioning components due to overuse of the filter.

[0037] According to the embodiment of the present invention, the method for monitoring the condition of an automotive air conditioning filter obtains the operating parameters of the blower, determines the dirt value of the air conditioning filter based on the operating parameters, and determines the degree of dirtiness of the air conditioning filter based on the dirt value range it falls within. Since the operating parameters of the blower can be obtained conveniently and accurately, the accuracy and convenience of judging the degree of dirtiness of the automotive air conditioning filter can be improved. This solves the problem of inaccurate monitoring of the condition of the automotive air conditioning filter, which easily leads to overuse or underuse of the automotive air conditioning filter. This ensures that the automotive air conditioning filter is fully utilized, reduces vehicle maintenance costs, and prevents damage to air conditioning components caused by overuse of the air conditioning filter.

[0038] Example 2

[0039] Based on Example 1, in this Example 2, determining the dirt value of the air conditioning filter according to operating parameters includes: determining the operating mode of the car air conditioner and the operating speed of the blower; determining the operating parameter-dirt value relationship curve model corresponding to the operating mode and operating speed in the curve model database, i.e., the pre-calibrated operating parameter-dirt value relationship curve model. The curve model database includes multiple operating parameter-dirt value relationship curve models for different operating modes and operating speeds; inputting the operating parameters into the pre-calibrated operating parameter-dirt value relationship curve model to obtain the dirt value corresponding to the operating parameters. The operating parameter-dirt value relationship curve model includes a mapping relationship between multiple operating parameters and the dirt values ​​corresponding to each of the multiple operating parameters.

[0040] In specific embodiments, the air conditioner's operating modes include, for example, a full-airflow internal circulation mode (commonly used for cooling) and a full-heat external circulation mode (commonly used for heating). The blower's operating speeds include, for example, speed 1 and speed 2 (determined by the OEM). Therefore, under different air conditioner operating modes and blower operating speeds, a blower operating parameter-dirt value relationship curve model can be pre-calibrated. For example, in the full-airflow internal circulation mode (commonly used for cooling), there are operating parameter-dirt value relationship curve models for speeds 1 and 2. Thus, multiple operating parameter-dirt value relationship curve models for different operating modes and speeds form a curve model database. In this embodiment of the invention, after determining the working mode of the car air conditioner and the working speed of the blower, the operating parameter-dirt value relationship curve model corresponding to the working mode and working speed can be determined in the curve model database. By inputting the operating parameters into the pre-calibrated operating parameter-dirt value relationship curve model, the dirt value corresponding to the current operating parameters can be obtained. Thus, the degree of dirtiness of the air conditioning filter can be determined according to the dirt value range in which the dirt value is located.

[0041] In Embodiment 2 of this invention, after determining the air conditioner's operating mode, for example, a full-cooling, internal circulation mode, the dirt levels corresponding to the blower's operating parameters at different operating speeds are determined to accurately assess the degree of dirt on the air conditioning filter. It should be noted that the car's air conditioning operating mode and blower speed can be manually set by the user via remote control or the car's air conditioning function buttons, or they can be automatically set according to the car's default operating mode and speed; no restrictions are imposed here.

[0042] According to the embodiment of the present invention, the method for monitoring the condition of an automotive air conditioning filter determines the operating mode and blower speed of the automotive air conditioning system, and determines the operating parameter-dirt value relationship curve model corresponding to the operating mode and speed in the curve model database. Then, the operating parameters are input into the determined operating parameter-dirt value relationship curve model to obtain the dirt value corresponding to the operating parameters. Based on the dirt value range in which the dirt value falls, the degree of dirtiness of the air conditioning filter is determined. Since the operating parameters of the blower can be obtained conveniently and accurately, the accuracy and convenience of judging the degree of dirtiness of the automotive air conditioning filter can be improved.

[0043] Example 3

[0044] Based on Embodiment 2, in this Embodiment 3, the operating parameters of the blower include the blower's operating current or operating power. It is understood that under the same operating conditions, the blower's operating voltage is stable, and the blower's operating current or operating power decreases as ventilation resistance increases. That is, the blower's operating current or operating power is inversely proportional to the dirt level or degree of dirt on the filter element. Therefore, by obtaining the blower's operating current or operating power, the degree of dirt on the air conditioning filter element can be accurately and conveniently identified, thus facilitating timely reminders to the vehicle owner to replace the filter element. In specific embodiments, the blower's operating current can be conveniently and accurately obtained through, but is not limited to, current detection devices or current detection circuits; the blower's operating power can be conveniently and accurately obtained through, but is not limited to, power detection devices or power detection circuits.

[0045] In one embodiment of the present invention, the relationship curve model between operating parameters and dirt values ​​is obtained by curve fitting of multiple sets of one-to-one correspondences between operating parameters and dirt values.

[0046] Specifically, when calibrating the blower's operating parameter-dirt value relationship curve model, the operating parameter values ​​of the blower can be experimentally determined under different air conditioning operating modes and blower operating speeds as the dirt value of the air conditioning filter changes from 0 to 100%. This involves obtaining multiple sets of one-to-one correspondences between operating parameters and dirt values ​​through experiments. Then, these multiple sets of operating parameter-dirt value correspondences are fitted to obtain the operating parameter-dirt value relationship curve model. It should be noted that the more sets of operating parameter-dirt value correspondences obtained through experiments, the more accurate the operating parameter-dirt value relationship curve model will be, and consequently, the more accurate the dirt value of the air conditioning filter determined based on the operating parameters.

[0047] For example, such as Figure 2 As shown, the explanation will be based on the operating current as the operating parameter. Figure 2 The curves represent the relationship between the operating current and the dirt level when the blower is at speed 1 and the air conditioner is in cooling and heating modes, respectively. For example, when the blower is at speed 1 and the air conditioner is in cooling mode, if the blower's operating current, as detected by the current detection circuit, is 6A, then... Figure 2 It can be seen that the dirt level of the air conditioning filter is 80%.

[0048] In one embodiment of the present invention, determining the degree of dirtiness of the air conditioning filter element based on the dirtiness value range includes: if the dirtiness value is less than the lower limit of a preset dirtiness value range, the air conditioning filter element is determined to be in a first degree of dirtiness; if the dirtiness value is within the preset dirtiness value range, the air conditioning filter element is determined to be in a second degree of dirtiness, wherein the second degree of dirtiness is greater than the first degree of dirtiness; if the dirtiness value is greater than the upper limit of the preset dirtiness value range, the air conditioning filter element is determined to be in a third degree of dirtiness, wherein the third degree of dirtiness is greater than the second degree of dirtiness.

[0049] In a specific embodiment, the preset dirt value range is, for example, [50%, 80%]. If the dirt value of the air conditioning filter obtained by the relationship curve model of operating parameters and dirt value is, for example, 30%, which is less than 50%, then the air conditioning filter is determined to be in the first dirt level. Similarly, if the dirt value of the air conditioning filter obtained by the relationship curve model of operating parameters and dirt value is, for example, 70%, then the air conditioning filter is determined to be in the second dirt level. If the dirt value of the air conditioning filter obtained by the relationship curve model of operating parameters and dirt value is, for example, 90%, then the air conditioning filter is determined to be in the third dirt level.

[0050] In one embodiment of the present invention, the method for monitoring the status of an automotive air conditioning filter further includes: issuing a reminder message to replace the filter when the degree of dirtiness is greater than a preset degree of dirtiness.

[0051] Specifically, if the preset dirt level is, for example, level three, then when the dirt level reaches level three, the cabin air filter is considered severely dirty and needs replacement. A replacement reminder will then be sent. This addresses the problem of inaccurate monitoring of the cabin air filter's condition, which can easily lead to overuse or underuse. It ensures the cabin air filter is used effectively, reducing vehicle maintenance costs, and preventing damage to air conditioning components due to overuse. It should be noted that the filter replacement reminder can be displayed as a text pop-up on an in-vehicle multimedia device such as a touchscreen DVD player, or it can be sent via Bluetooth to a smart terminal such as a mobile phone for voice reminders; there are no restrictions on this.

[0052] In one embodiment of the present invention, the method for monitoring the status of an automotive air conditioning filter further includes: displaying different icons or text information on a display device according to different levels of dirt on the air conditioning filter.

[0053] Specifically, if the display device is, for example, a touch-screen DVD display, different icons or text information can be displayed on the display device to make the degree of dirtiness of the air conditioning filter clear at a glance, so that users can understand the condition of the air conditioning filter in a timely manner.

[0054] In a specific embodiment, when the dirt level of the air conditioning filter is within the dirt level range [0, 50%], the filter is considered to be not too dirty, and a green icon or text is displayed on the display device at the location indicating the dirt level. When the dirt level is within the dirt level range [50%, 80%], the filter is considered to be relatively dirty, and a yellow icon or text is displayed on the display device at the location indicating the dirt level. When the dirt level is within the dirt level range [80%, 100%], the filter is considered to be severely dirty and needs to be replaced soon, and a red icon or text is displayed on the display device at the location indicating the dirt level to remind the user to replace the filter in time. This makes the dirt level of the air conditioning filter clear at a glance, allowing users to understand the usage status of the air conditioning filter in a timely manner. According to the embodiment of the present invention, the method for monitoring the status of an automotive air conditioning filter obtains the operating parameters of the blower, determines the dirt value of the air conditioning filter based on the operating parameters, and determines the degree of dirtiness of the air conditioning filter based on the dirt value range. Then, the degree of dirtiness of the automotive air conditioning filter is displayed on a display device by displaying different icons or text information. When the degree of dirtiness of the air conditioning filter is severe, a reminder message to replace the filter is issued. This method makes the degree of dirtiness of the air conditioning filter clear at a glance, making it convenient for users to understand the usage status of the air conditioning filter and replace it in a timely manner.
