[0001] The present application relates to the technical field of vehicle monitoring, and in particular to a vehicle window fogging processing method, device, equipment and storage medium. BACKGROUND

[0002] During the use of a vehicle, the phenomenon of glass "fogging" often occurs, for example, when driving in the morning in winter or in rainy weather in summer. The main reasons for this phenomenon are: 1. High humidity in the vehicle, especially for large-area panoramic sunroofs, the use of a sunroof, combined with the high humidity emitted by the human body, leading to the breeding of bacteria and odors in the vehicle, which is harmful to the health of the occupants. 2. There is a certain temperature difference between the inside and outside of the vehicle, and glass fogging will cause poor driving visibility, which can easily cause traffic accidents. There are various forms of "fogging" in a vehicle, including internal fogging and external fogging. The prior art solution cannot accurately determine whether the fogging occurs on the inside or outside of the glass, and cannot provide effective information to the driver.

[0003] Therefore, how to accurately determine the source of the fog and remove it in time is a technical problem that needs to be solved at present. SUMMARY

[0004] The main purpose of the present application is to provide a vehicle window fogging processing method, device, equipment and storage medium, which can effectively determine the source of the fog and prompt the driver to take appropriate countermeasures, thereby avoiding the occurrence of safety accidents caused by visual obstruction.

[0005] In a first aspect, the present application provides a vehicle window fogging processing method, wherein the method comprises the following steps:

[0006] Collecting the temperature inside and outside the vehicle, the humidity inside and outside the vehicle, and the light transmittance of the vehicle window;

[0007] Based on the current region, driving environment, temperature inside and outside the vehicle, humidity change inside and outside the vehicle, and light transmittance of the vehicle window, determining the position of the fogging source;

[0008] According to the position of the fogging source, the corresponding defogging strategy is performed in advance.

[0009] In combination with the above first aspect, as an optional implementation manner,

[0010] If the vehicle is in an underground parking lot, the temperature inside the vehicle is greater than the temperature outside the vehicle, there is a user inside the vehicle, and the light transmittance of the vehicle window is less than a threshold value, it is determined that the fogging source is inside the vehicle;

[0011] If the vehicle is currently in a first preset region, there is a user inside the vehicle, the humidity inside the vehicle is greater than the humidity outside the vehicle, and the light transmittance of the vehicle window is less than a threshold value, it is determined that the fogging source is inside the vehicle;

[0012] If the vehicle is currently in the second preset area and the vehicle is in a wet and rainy driving environment, it is detected that the temperature inside the vehicle is less than the temperature outside the vehicle, the humidity outside the vehicle is greater than the humidity inside the vehicle, and the light transmittance of the vehicle window is less than a threshold value, and it is determined that the source of the fog is outside the vehicle.

[0013] If the vehicle is in a foggy and wet driving environment, it is detected that the temperature outside the vehicle is greater than the temperature inside the vehicle, the humidity outside the vehicle is greater than the humidity inside the vehicle, and the light transmittance of the vehicle window is less than a threshold value, and it is determined that the source of the fog is outside the vehicle.

[0014] If the vehicle is in an open-air driving environment, it is detected that the humidity outside the vehicle is less than the humidity inside the vehicle, the temperature outside the vehicle is less than the temperature inside the vehicle, and the light transmittance of the vehicle window is less than a threshold value, and it is determined that the source of the fog is inside the vehicle.

[0015] In combination with the first aspect, as an optional implementation manner, if it is detected that the temperature inside the vehicle is relatively low to the humidity and temperature outside the vehicle, it is determined that the vehicle interior glass has a fogging trend.

[0016] If it is detected that the temperature inside the vehicle is relatively high to the humidity and temperature outside the vehicle, it is determined that the vehicle exterior glass has a fogging trend.

[0017] In combination with the first aspect, as an optional implementation manner, when the vehicle is in summer, if it is determined that the vehicle interior glass has a fogging trend, the A / C switch of the vehicle is turned on in advance and the temperature is adjusted to the lowest, and the interior circulation mode is turned on, to prevent the fog existing in the vehicle interior glass;

[0018] When the vehicle is in winter, if it is determined that the vehicle interior glass has a fogging trend, the air conditioner is turned on in advance and adjusted to a preset temperature, or the windshield heating function is turned on, to prevent the fog existing in the vehicle interior glass;

[0019] If it is determined that the vehicle exterior glass has a fogging trend, the front windshield glass adopts a wiper mode, the rearview mirror adopts a heating mode, and the glass on both sides of the vehicle door adopts an interior circulation mode, to prevent the fog existing in the vehicle exterior glass.

[0020] In combination with the first aspect, as an optional implementation manner, if the defogging strategy is removed in advance, the clarity of the vehicle glass is detected by using a haze detection sensor;

[0021] If it does not meet the standard, a prompt is given.

[0022] In combination with the first aspect, as an optional implementation manner, the degree of fogging, the degree of snow accumulation, the degree of ice layer and the degree of dust on the vehicle glass are detected by using the haze meter.

When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention.

[0038] This application provides a method, apparatus, device, and storage medium for dealing with fogging of vehicle windows, which can effectively determine the source of fogging and prompt the driver to take corresponding countermeasures, thereby avoiding obstruction of vision and the occurrence of safety accidents.

[0039] To achieve the aforementioned technical effects, the general concept of this application is as follows:

[0040] A method for dealing with fogging on car windows, the method comprising the following steps:

[0041] S101: Collects the temperature and humidity inside and outside the vehicle, as well as the light transmittance of the windows.

[0042] S102: Determine the location of the fogging source based on the current location, driving environment, changes in temperature and humidity inside and outside the vehicle, and the light transmittance of the windows.

[0043] S103: Implement appropriate defogging strategies in advance based on the location of the fogging source.

[0044] The embodiments of this application will be further described in detail below with reference to the accompanying drawings.

[0045] Reference Figure 1 , Figure 1 The diagram shown is a flowchart of a method for dealing with fogging of car windows provided by the present invention. Figure 1 As shown, the method includes the following steps:

[0046] Step S101: Collect the temperature inside and outside the vehicle, the humidity inside and outside the vehicle, and the light transmittance of the windows.

[0047] Specifically, humidity sensors are used to collect data on the vehicle's interior and exterior temperatures, as well as the interior and exterior humidity. It's important to understand that a humidity sensor is a device that detects changes in external humidity and converts this humidity into a useful signal through changes in the physical or chemical properties of its materials. Humidity detection is more challenging than detecting other physical quantities, primarily because the water vapor content in the air is much lower than that in the cabin. The humidity is calculated by collecting data from the humid air exhaled by occupants and changes in interior and exterior temperatures. A humidity sensor can collect data from the humid air exhaled by cabin occupants, collecting humidity change thresholds (e.g., increasing in 1% RH increments from 30% RH, i.e., 31% RH, 32% RH, 33% RH, etc.). The rate of change varies with the number of occupants, affecting whether the vehicle is occupied by a single person or is fully loaded.

[0048] Optionally, a haze meter can be installed on the windshield. This haze meter can detect the light transmittance of the windshield and monitor fog. In addition, it can also monitor snow, ice, and dust.

[0049] It's important to explain that haze is the ratio of scattered light flux deviating from the incident light direction to the transmitted light flux, expressed as a percentage. Typically, only scattered light flux deviating from the incident light direction by more than 2.5 degrees (fogging) is used to calculate haze. For example, if haze is detected above 2.5 degrees, the car window is considered fogged; if haze is detected below 2.5 degrees (in other words, if the window transmittance is greater than 70%, it's not fogged; if the window transmittance is less than 70%, it's fogged, or other factors such as rain, snow, or dust indicate fogging), the window is not considered fogged. Furthermore, it should be noted that haze meters are used for monitoring the driver's field of vision, detecting haze in the windshield area, the left and right front windshield areas, and the rear windshield area.

[0050] Step S102: Based on the current location, driving environment, changes in temperature and humidity inside and outside the vehicle, and light transmittance of the windows, determine the location of the fogging source.

[0051] Specifically, determining whether the source of vehicle fogging is inside or outside the vehicle is based on the driving environment, temperature, and humidity. For example, if the vehicle is in an underground parking lot, and the interior temperature is higher than the outside temperature, there are users inside the vehicle, and the window light transmittance is greater than 70%, then the source of fogging is determined to be inside the vehicle. It's understandable that interior fogging primarily occurs in scenarios (like winter parking lots) where the temperature inside and outside the vehicle is relatively balanced when no one is in the passenger compartment. However, once passengers are seated, the humidity increases due to the humid air (water vapor) exhaled by the occupants. It's important to explain that when the outside temperature is low, the water vapor exhaled by passengers condenses into small water droplets that adhere to the car window surface, forming fog.

[0052] If the vehicle is currently in the first preset area, and a user is detected inside the vehicle, the humidity inside the vehicle is greater than the humidity outside the vehicle, and the light transmittance of the windows is less than the threshold, then it is determined that the source of fogging is inside the vehicle.

[0053] There are differences in temperature and humidity between southern and northern regions. Northern regions generally have a dry climate, so fogging outside the car is less common; it usually occurs inside. Southern regions are humid and rainy, leading to various complex situations, such as fogging on the inside or outside of the car. Different actions are required depending on the situation. Therefore, including the region can help in more accurately assessing the fogging situation.

[0054] If the vehicle is currently in a northern region (the first preset region), and a user is detected inside the vehicle, the humidity inside the vehicle is greater than the humidity outside the vehicle, and the light transmittance of the windows is less than the threshold, then the source of the fogging is determined to be inside the vehicle.

[0055] If the vehicle is currently in a humid and rainy driving environment in the second preset region, and the detected interior temperature is lower than the outside temperature, the outside humidity is higher than the interior humidity, and the window light transmittance is lower than the threshold, then the source of fogging is determined to be outside the vehicle. This is understandable if the vehicle is in a southern region (the second preset region), in a summer and rainy driving environment, and the detected interior temperature is lower than the outside temperature, the detected outside humidity is higher than the interior humidity, and the window light transmittance is lower than the threshold; in this case, the source of fogging is outside the vehicle. This is understandable because the interior temperature is lower than the outside temperature, the outside humidity is high, fog adheres to the exterior windows, and this occurs in the rainy season of summer (external fogging).

[0056] If a vehicle is in a foggy and humid driving environment, and the outside temperature is higher than the inside temperature, the outside humidity is higher than the inside humidity, and the window light transmittance is below a threshold, then the source of the fogging is outside the vehicle. This can be understood as the outside temperature being higher than the inside temperature, and the outside humidity being higher than the inside humidity, while driving in a foggy and humid environment (external fogging).

[0057] If a vehicle is in an open-air driving environment, and the detected outside humidity is lower than the inside humidity, the detected outside temperature is lower than the inside temperature, and the window light transmittance is below a threshold, then the source of fogging is inside the vehicle. This is understandable, as the outside humidity is lower than the inside humidity, and the outside temperature is lower than the inside temperature; during the rainy season in autumn, vehicles parked outdoors for extended periods will experience fogging inside.

[0058] In addition, it should be explained that a light transmittance of more than 70% indicates that fogging has not occurred, while less than 70% indicates that fogging has occurred, or that other factors are interfering, such as rain, wind, sand, ice, and snow.

[0059] In northern regions, where there is a lot of ice and snow, windshield wipers can easily freeze and become unusable. In such cases, it is necessary to rely on the air conditioning to blow hot air to defrost and defog, as well as the heated exterior mirrors and rear window functions.

[0060] In southern regions, it's necessary to determine if fogging occurs on both the inner and outer sides of the windows, and if fogging is likely to occur while driving. Besides relying on the air conditioning system for defogging, if fogging occurs on the outer side of the windshield, the wipers should be used to defog it; if fogging occurs on the outer sides of all four door windows, the windows should be defogged using the power windows.

[0061] Optionally, if the vehicle is in dry or hot weather, the humidity difference between the inside and outside of the vehicle is detected within a first preset range; the temperature difference between the inside and outside of the vehicle is detected within a second preset range, then it is determined that there is no tendency for the vehicle windows to fog up. It is understandable that fogging is less likely to occur in the relatively cool spring or dry summer (the hottest days of summer), as humidity and temperature are more balanced and less prone to change (no fogging).

[0062] In one embodiment, if the temperature inside the vehicle is detected to be increasing relative to the ambient humidity and temperature, it is determined that the interior glass of the vehicle is prone to fogging (e.g., when leaving a parking lot); if the temperature inside the vehicle is detected to be decreasing relative to the ambient humidity and temperature, it is determined that the exterior glass of the vehicle is prone to fogging (e.g., when entering a parking lot).

[0063] Optionally, a vehicle fogging reference (when the outside temperature T2 = 16℃ and the relative humidity inside the vehicle is greater than or equal to 30%RH, fogging begins to form on the inside of the windows) is established. At this time, the humidity sensor detects the temperature inside and outside the vehicle and summarizes the data to the vehicle ECU. At the same time, the humidity sensor collects the humidity inside and outside the vehicle. When the humidity inside the vehicle reaches 30%RH, the information is summarized by the vehicle ECU and calculated. If the indoor temperature is lower than the outdoor temperature and the humidity reaches 30%RH, fog will form on the inside of the glass. The monitoring vision device will then feed back the source of the problem to the driver to remind the driver to take appropriate defogging measures.

[0064] Step S103: Implement appropriate defogging strategies in advance based on the location of the fogging source.

[0065] Specifically, based on the current location, driving environment, changes in temperature and humidity inside and outside the vehicle, and the light transmittance of the windows, the location of the fogging source is determined. When the vehicle is in summer, if it is determined that there is a tendency for the interior glass to fog up, the vehicle's A / C switch is turned on in advance, the temperature is set to the lowest level, and the internal circulation mode is turned on to prevent fogging on the interior glass.

[0066] When the vehicle is in winter, if you are sure that the interior windows are about to fog up, turn on the air conditioning in advance and set it to the preset temperature, or turn on the window defrosting function to prevent fogging on the interior windows.

[0067] For example, when a driver receives a fogging warning from inside the car, in summer, they should first turn on the A / C, set the temperature to the lowest setting, switch to recirculation mode, and adjust the fan speed; the fog on the windshield will quickly dissipate. In winter, they can use cool air (normal temperature, i.e., 25°C) to defog, or turn on the air conditioning or the car's front and rear window defoggers and heating functions. The physical principle behind this is that by accelerating the airflow over the liquid surface, the evaporation rate is increased.

[0068] If it is determined that the exterior windows are likely to fog up, the windshield wipers will be used, the side mirrors will be heated, and the windows on both sides of the doors will be set to internal air circulation mode to prevent fogging.

[0069] It's important to note that fogging on the exterior of the glass primarily occurs during rainy summer months. When fog appears on the outside of the glass, it's due to a significant temperature difference between the inside and outside of the car, coupled with higher humidity outside. This causes moisture in the outside air to condense on the cooler glass surface. This fogging typically occurs when the air conditioning is on inside the car, and it's most common on the windshield. The main reason is that the cold air blowing from the windshield vents is directed at a specific area of ​​the glass for an extended period, creating a large temperature difference between the glass and the ambient air, leading to fogging on the outside. In this situation, use the windshield wipers to clear the fog, use the heated side mirrors to clear the fog, and use the internal air circulation mode on the side windows to defog.

[0070] In one embodiment, a haze meter detects the degree of fog on the vehicle's windshield. When fog forms, if the user activates the defroster and prematurely cancels the defroster, a haze detection sensor checks if the windshield's clarity meets the required standard. If the windshield's clarity is below standard, a warning is issued, such as a windshield visibility obstruction warning, to alert the driver and prompt them to employ appropriate strategies to clear the fog. It is understood that even when the driver stops the defroster operation, the presence of fog may still be difficult to discern with the naked eye. Therefore, alerting the driver when the fog level is insufficient indicates a potential safety risk.

[0071] It is understood that the method, apparatus, equipment, and storage medium for handling vehicle window fogging provided in this application include the following steps: collecting the temperature and humidity inside and outside the vehicle, as well as the light transmittance of the vehicle window; determining the location of the fogging source based on the current location, driving environment, changes in temperature and humidity inside and outside the vehicle, and the light transmittance of the vehicle window; and implementing appropriate defogging strategies in advance depending on whether the fogging source is inside or outside the vehicle. This method can effectively identify the source of fogging when visibility is impaired due to fogging in environments with high humidity or large temperature differences between indoors and outdoors, informing the driver of the cause of the impaired visibility and providing operational countermeasures to quickly restore visibility, ensure driving safety, and prevent accidents. Furthermore, it can monitor indoor and outdoor humidity in real time to prevent fogging, control indoor humidity, and reduce the probability of fogging in areas with high rainfall, preventing mold growth and a poor driving environment.

[0072] Reference Figure 2 , Figure 2 The diagram shown is a schematic of a car window fogging treatment device provided by the present invention. Figure 2 As shown, the device includes:

[0073] Data acquisition module 201: It is used to collect the temperature inside and outside the vehicle, the humidity inside and outside the vehicle, and the light transmittance of the windows.

[0074] Judgment module 202: It is used to determine the location of the fogging source based on the current location, driving environment, changes in temperature and humidity inside and outside the vehicle, and light transmittance of the windows.

[0075] Execution module 203: It is used to implement corresponding defogging strategies in advance based on the location of the fogging source.

[0076] Furthermore, in one possible implementation, the determination module is also used for

[0077] If the vehicle is in an underground parking lot, and the temperature inside the vehicle is higher than the outside temperature, there is a user inside the vehicle, and the light transmittance of the windows is less than the threshold, then the source of the fogging is determined to be inside the vehicle.

[0078] If the vehicle is currently in the first preset area, and a user is detected inside the vehicle, the humidity inside the vehicle is greater than the humidity outside the vehicle, and the light transmittance of the windows is less than the threshold, then it is determined that the source of fogging is inside the vehicle.

[0079] If the vehicle is currently in the second preset area and the driving environment is humid and rainy, and the temperature inside the vehicle is lower than the outside temperature, the outside humidity is higher than the inside humidity, and the light transmittance of the windows is lower than the threshold, then it is determined that the source of fogging is outside the vehicle.

[0080] If a vehicle is in a foggy and humid driving environment, and the outside temperature is higher than the inside temperature, the outside humidity is higher than the inside humidity, and the window light transmittance is less than the threshold, then the source of fogging is determined to be outside the vehicle.

[0081] If the vehicle is in an open-air driving environment, and the external humidity is lower than the internal humidity, the external temperature is lower than the internal temperature, and the window light transmittance is lower than the threshold, then the source of fogging is determined to be inside the vehicle.

[0082] Furthermore, in one possible implementation, the judgment module is also used to determine that the interior glass has a tendency to fog up if the detected interior temperature is increasing relative to the external humidity and temperature.

[0083] If the temperature inside the car decreases relative to the outside humidity and temperature, it indicates that the exterior windows are showing a tendency to fog up.

[0084] Furthermore, in one possible implementation, the execution module is also configured to, when the vehicle is in summer, if it is determined that there is a tendency for the interior glass to fog up, turn on the vehicle A / C switch in advance and set the temperature to the lowest level, and turn on the internal circulation mode to prevent fogging on the interior glass.

[0085] When the vehicle is in winter, if you are sure that the interior windows are about to fog up, turn on the air conditioning in advance and set it to the preset temperature, or turn on the window defrosting function to prevent fogging on the interior windows.

[0086] If it is determined that the exterior windows are likely to fog up, the windshield wipers will be used, the side mirrors will be heated, and the windows on both sides of the doors will be set to internal air circulation mode to prevent fogging.

[0087] Furthermore, in one possible implementation, the judgment module is also used to detect whether the clarity of the vehicle glass meets the standard if the defogging strategy is prematurely deactivated;

[0088] If the standard is not met, a prompt will be displayed.

[0089] Furthermore, in one possible implementation, the acquisition module is also used to detect the degree of fogging, snow accumulation, ice layer, and dust on the vehicle glass using the haze meter.

Claims

1. A method for dealing with fogging of car windows, characterized in that, include: Collect data on the temperature and humidity inside and outside the vehicle, as well as the light transmittance of the windows. Based on the current location, driving environment, changes in temperature and humidity inside and outside the vehicle, and the light transmittance of the windows, the location of the fogging source is determined. If the vehicle is in an underground parking lot, and the detected interior temperature is higher than the outside temperature, there is a user inside the vehicle, and the light transmittance of the windows is less than the threshold, then the source of the fogging is determined to be inside the vehicle. If the vehicle is currently in a northern region, and the presence of a user inside the vehicle, the humidity inside the vehicle being greater than the humidity outside the vehicle, and the light transmittance of the windows being less than the threshold are detected, then the source of the fogging is determined to be inside the vehicle. If the vehicle is currently in a humid and rainy driving environment in the south, and the detected interior temperature is lower than the outside temperature, the outside humidity is higher than the interior humidity, and the window light transmittance is lower than the threshold, then the source of fogging is determined to be outside the vehicle. If a vehicle is in a foggy and humid driving environment, and the outside temperature is higher than the inside temperature, the outside humidity is higher than the inside humidity, and the window light transmittance is less than the threshold, then the source of fogging is determined to be outside the vehicle. If the vehicle is in an open-air driving environment, and the external humidity is lower than the internal humidity, the external temperature is lower than the internal temperature, and the window light transmittance is lower than the threshold, then the source of fogging is determined to be inside the vehicle. Based on the location of the fog source, implement appropriate defogging strategies in advance.

2. The method according to claim 1, characterized in that, Also includes: If the vehicle is in dry or hot weather, the humidity difference between the inside and outside of the vehicle is detected within the first preset range. If the temperature difference between the inside and outside of the vehicle is within a second preset range, it is determined that the vehicle windows do not have a tendency to fog up.

3. The method according to claim 1, characterized in that, Also includes: If the temperature inside the car is detected to be increasing relative to the outside humidity and temperature from low to high, it is determined that the car windows are showing a tendency to fog up. If the temperature inside the car decreases relative to the outside humidity and temperature, it indicates that the exterior windows are showing a tendency to fog up.

4. The method according to claim 1, characterized in that, The aforementioned defogging strategy, implemented in advance based on the location of the fogging source, includes: When the vehicle is in summer, if you are sure that the interior windows are going to fog up, turn on the vehicle's A / C switch in advance, set the temperature to the lowest setting, and turn on the recirculation mode to prevent fogging on the interior windows. When the vehicle is in winter, if you are sure that the interior windows are about to fog up, turn on the air conditioning in advance and set it to the preset temperature, or turn on the window defrosting function to prevent fogging on the interior windows. If it is determined that the exterior windows are likely to fog up, the windshield wipers will be used, the side mirrors will be heated, and the windows on both sides of the doors will be set to internal air circulation mode to prevent fogging.

5. The method according to claim 4, characterized in that, Also includes: If the defogging strategy is discontinued in advance, the fog detection sensor will be used to check whether the clarity of the vehicle glass meets the standard. If the standard is not met, a prompt will be displayed.

The judgment module is used to determine the location of the fogging source based on the current location, driving environment, changes in temperature and humidity inside and outside the vehicle, and the light transmittance of the windows. If the vehicle is in an underground parking lot, and the temperature inside the vehicle is higher than the outside temperature, there is a user inside the vehicle, and the light transmittance of the windows is less than the threshold, then the source of the fogging is determined to be inside the vehicle. If the vehicle is currently in a northern region, and the presence of a user inside the vehicle, the humidity inside the vehicle being greater than the humidity outside the vehicle, and the light transmittance of the windows being less than the threshold are detected, then the source of the fogging is determined to be inside the vehicle. If the vehicle is currently in a humid and rainy driving environment in the south, and the detected interior temperature is lower than the outside temperature, the outside humidity is higher than the interior humidity, and the window light transmittance is lower than the threshold, then the source of fogging is determined to be outside the vehicle. If a vehicle is in a foggy and humid driving environment, and the outside temperature is higher than the inside temperature, the outside humidity is higher than the inside humidity, and the window light transmittance is less than the threshold, then the source of fogging is determined to be outside the vehicle. If the vehicle is in an open-air driving environment, and the external humidity is lower than the internal humidity, the external temperature is lower than the internal temperature, and the window light transmittance is lower than the threshold, then the source of fogging is determined to be inside the vehicle.
