Description

Technical Field

[0001] The present invention relates to the technical field of vehicle monitoring, and in particular to a vehicle window fogging treatment method, device, equipment and storage medium. Background Art

[0002] In the process of using the car, the glass often "fogs up", such as when driving in the morning in winter, driving in the rain in summer, etc. The main reasons for this phenomenon are: 1. The air humidity in the car is high, especially when using a large panoramic sunroof and skylight, and the human body emits high humidity, which causes bacteria and odor to grow in the car, which is harmful to the health of the people in the car. 2. There is a certain temperature difference between the inside and the outside of the car. The fogging of the glass will lead to poor driving vision. The driver's loss of vision can easily cause traffic accidents. There are many forms of "fogging" in cars, including internal fogging and external fogging. The existing technical solutions cannot accurately determine whether it occurs on the inside or outside of the glass, and cannot provide the driver with effective information.

[0003] Therefore, how to accurately determine the source of fogging and remove it in a timely manner is a technical problem that urgently needs to be solved. Summary of the invention

[0018] When the vehicle is in winter, if it is determined that the interior glass has a tendency to fog up, turn on the air conditioner in advance and adjust it to the preset temperature, or turn on the window heating function to prevent the interior glass from fogging up;

[0019] If it is determined that the exterior glass of the vehicle has a tendency to fog, the front windshield will be wiped, the rearview mirror will be heated, and the glass on both sides of the door will be circulated internally to prevent fogging on the exterior glass.

[0036] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0037] Furthermore, the drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. Some of the blocks shown in the drawings are functional entities and do not necessarily correspond to physically or logically separate entities.

[0038] The embodiments of the present application provide a vehicle window fogging treatment method, device, equipment and storage medium, which can effectively determine the source of fogging and prompt the driver to take corresponding countermeasures, thereby avoiding safety accidents caused by obstructed vision.

[0039] In order to achieve the above technical effects, the general idea of ​​this application is as follows:

[0040] A method for treating vehicle window fogging, the method comprising the steps of:

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

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

[0043] S103: Implement corresponding defog strategies in advance according to the location of the fog source.

[0044] The embodiments of the present application are further described in detail below in conjunction with the accompanying drawings.

[0045] Reference Figure 1 , Figure 1 FIG. 1 is a flow chart of a vehicle window fogging treatment method provided by the present invention, as shown in FIG. Figure 1 As shown, the method comprises the steps of:

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

[0047] Specifically, humidity sensors are used to collect the temperature inside the car, the temperature outside the car, the humidity inside the car, and the humidity outside the car. It needs to be explained that humidity sensors are devices that can sense changes in external humidity and convert humidity into useful signals through changes in the physical or chemical properties of the device material. Humidity detection is more difficult than the detection of other physical quantities. This is firstly because the water vapor content in the air is much less than that in the air. The humidity is measured and collected (humid gas exhaled by people in the cabin, temperature changes inside and outside the car). Real-name sensors can collect humid air exhaled by cabin personnel and collect humidity change thresholds (for example, from 30%RH every 1%RH upward, that is, 31%RH, 32%RH, 33%RH...etc.). The speed of change varies with the number of people in the car, and is affected by a single person and a full load of people.

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

[0049] It should be explained that haze is the ratio of the scattered light flux that deviates from the direction of the incident light through the sample to the transmitted light flux, expressed as a percentage. Usually, only the scattered light flux that deviates from the direction of the incident light by more than 2.5 degrees (fogging) is used to calculate the haze. For example, if the haze is detected to be above 2.5 degrees, it is judged that the car window has been fogged. If the haze is detected to be below 2.5 degrees (in other words, if the light transmittance of the car window is greater than 70%, it means that it is not fogged, if the light transmittance of the car window is less than 70%, it means that it is fogged, or other factors, such as rain, ice and snow, dust, etc.), it is judged that the car window is not fogged. In addition, it should be explained that the haze meter is used to monitor the driver's driving field of vision, the front windshield area, the left front and right front glass areas, and the rear windshield area.

[0050] Step S102: Determine the location of the fogging source based on the current region, driving environment, changes in temperature and humidity inside and outside the vehicle, and window transmittance.

[0051] Specifically, the source of fogging of the vehicle is detected whether it is inside or outside the vehicle, and it is judged by the driving environment, temperature and humidity. For example, if the vehicle is in an underground parking lot, the temperature inside the car is detected to be greater than the outside temperature, the presence of users in the car is detected, and the light transmittance of the window is greater than 70%, and it is judged that the source of fogging is inside the car. It is understandable that the fogging on the inside mainly occurs in the scene (the scene in the parking lot in winter). When there is no one in the passenger compartment, the temperature inside and outside the car and the humidity on the glass are in relative balance. After the passenger compartment is occupied, the humidity of the humid air (water vapor) exhaled by the cabin occupants. It needs to be explained that when the temperature outside the car is low, the water vapor exhaled by the people in the car condenses into small water droplets when it encounters cold and adheres to the surface of the car glass to form fog.

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

[0053] There are differences in temperature and humidity between the southern and northern regions. The northern region has a dry climate, so fogging outside the car is not easy to occur, but fogging inside the car often occurs. The south is humid and rainy, so it is easy to have a variety of complex situations, such as fogging inside and outside. Different operations are required for different situations. Therefore, adding regions can more accurately judge the fogging situation.

[0054] Among them, if the vehicle is currently in the northern region (the first preset region), it is detected that there is a user in the car, the humidity inside the car is greater than the humidity outside the car, and the window transmittance is less than a threshold, then it is determined that the source of fogging is inside the car.

[0055] If the vehicle is currently in the second preset area and the driving environment is humid and rainy, the detected temperature inside the car is lower than the outside temperature, the outside humidity is higher than the humidity inside the car, and the window transmittance is lower than the threshold, then it is judged that the source of fogging is outside the car. It is understandable that if the vehicle is in the southern region (the second preset area), in the summer and rainy driving environment, the detected temperature inside the car is lower than the outside temperature, the detected outside humidity is higher than the humidity inside the car, and the window transmittance is lower than the threshold, then the source of fogging is outside the car. It is understandable that the temperature inside the car is lower than the outside temperature, the outside humidity is high, fog is attached to the external glass, and it is a driving environment in the rainy season in summer (external fogging).

[0056] If the vehicle is in a foggy and humid driving environment, the detected outside temperature is greater than the inside temperature, the detected outside humidity is greater than the inside humidity, and the window transmittance is less than the threshold, then the source of fogging is outside the vehicle. It can be understood that the outside temperature is greater than the inside temperature, and the outside humidity is greater than the inside humidity, and the vehicle is driving in a special environment with fog and humidity (external fogging).

[0057] If the vehicle is in an open-air driving environment, the detected outside humidity is lower than the inside humidity, the detected outside temperature is lower than the inside temperature, and the window transmittance is lower than the threshold, then the fogging source is inside the vehicle. It is understandable that the outside humidity is lower than the inside humidity, and the outside temperature is lower than the inside temperature, and the vehicle is parked in the open air for a long time in the rainy autumn season (fogging inside).

[0058] In addition, it needs to be explained that if the window transmittance is greater than 70%, it means that there is no fogging. If it is less than 70%, it is judged that there is fogging, or there are other interference factors, such as rain, wind, sand, ice and snow.

[0059] In the northern region, there is a lot of ice and snow, and the wipers are easily frozen and cannot be used. The air conditioner's hot air is used for defrosting and deicing, and the exterior rearview mirrors and rear glass heating functions are used together.

[0060] In the southern region, it is necessary to judge whether the inside and outside are fogged, and it is possible that fogging may occur while driving. In addition to relying on the air conditioning system to clear, if the outside of the front windshield is fogged, it needs to be defogged with a wiper, and if the outside of the four-door glass is fogged, it needs to be defogged by lifting the glass.

[0061] Optionally, if the vehicle is in dry or hot weather, the difference between the humidity inside and outside the vehicle is detected to be within a first preset range; the difference between the temperature inside and outside the vehicle is detected to be within a second preset range, then it is determined that the vehicle glass does not have a tendency to fog. It is understandable that fogging is not easy to occur in spring when the temperature is relatively cool, or in summer when it is dry (dog days), and the humidity and temperature are balanced and not easy to change (no fog).

[0062] In one embodiment, if the detected temperature inside the vehicle changes from low to high relative to the outside humidity and temperature, it is judged that the glass inside the vehicle has a tendency to fog (for example, a scene when leaving a parking lot); if the detected temperature inside the vehicle changes from high to low relative to the outside humidity and temperature, it is judged that the glass outside the vehicle has a tendency to fog (for example, a scene when entering a parking lot).

[0063] Optionally, a reference for fogging of a driving vehicle (when the outside temperature is T2 = 16°C standard atmospheric pressure, the inside of the window begins to fog when the relative humidity inside the vehicle is greater than or equal to 30% RH). At this time, the humidity sensor senses the temperature inside and outside the vehicle and summarizes the data to the monitoring vehicle ECU. At the same time, the humidity sensor collects the humidity inside and outside the vehicle. When the humidity inside the vehicle reaches 30RH, the information is summarized by the vehicle ECU for calculation. If the indoor temperature is lower than the outdoor temperature and the humidity reaches 30RH, fog is generated on the inside of the glass. The field of view monitoring device will feedback the source of the problem to the driver to remind the driver to implement the corresponding defogger strategy.

[0064] Step S103: Implement corresponding defogging strategies in advance according to the location of the fog source.

[0065] Specifically, the location of the fogging source is determined based on the current region, driving environment, temperature and humidity changes inside and outside the vehicle, and window transmittance. When the vehicle is in summer, if it is determined that the glass inside the vehicle has a tendency to fog, turn on the vehicle's A / C switch in advance and adjust the temperature to the lowest, and turn on the internal circulation mode to prevent fogging on the glass inside the vehicle.

[0066] When the vehicle is in winter, if it is determined that the glass inside the car has a tendency to fog up, turn on the air conditioner in advance and adjust it to the preset temperature, or turn on the window heating function to prevent fogging on the glass inside the car.

[0067] For example, when the driver receives a message that the interior of the car is fogged, if it is summer, first turn on the A / C switch, adjust the temperature to the lowest, turn on the internal circulation mode, and then adjust the air volume, the fog on the front windshield will be quickly eliminated; if it is winter, blow cold air (normal temperature wind, i.e. 25°C) to defog, turn on the air conditioner or the front and rear window defogger and function (heating function) on the vehicle. The physical principle of this approach is that by accelerating the air flow on the surface of the liquid, its evaporation rate is accelerated.

[0068] If it is determined that the exterior glass of the vehicle has a tendency to fog, the front windshield will be wiped, the rearview mirror will be heated, and the glass on both sides of the door will be circulated internally to prevent fogging on the exterior glass.

[0069] It should be noted that fogging on the outside mainly occurs when there is a lot of rain in summer. When water mist appears on the outside of the glass, it is because the temperature difference between the inside and outside of the car is large, and the humidity outside the car is high. Therefore, the moisture in the air outside the car will condense on the colder glass surface and become water mist. It usually occurs when the air conditioner is turned on in the car, and it is most likely to occur on the front windshield. The main reason is that the cold air blown out of the front windshield outlet is directed at a certain area of ​​the glass for a long time, resulting in a large difference between the glass temperature and the ambient temperature, which causes water mist to appear on the outside of the glass. At this time, the front windshield is defogged with a wiper, the exterior rearview mirror is defogged by heating, and the glass on both sides is defogged by internal circulation.

[0070] In one embodiment, the degree of fog on the vehicle glass is detected by a haze meter. When fogging occurs, if the user turns on the defogger and the defogger strategy is released in advance, the haze detection sensor is used to detect whether the clarity of the vehicle glass meets the standard. If the clarity of the vehicle glass does not meet the standard, a prompt is given, such as a warning of obstruction of the windshield area, to remind the driver to use a corresponding strategy to remove the fog on the glass. It is understandable that when the driver stops the defogger operation, because the naked eye cannot clearly see whether there is still fog, therefore, when the haze does not meet the requirements, the driver is reminded that there is a safety risk.

[0071] It is understandable that the present application provides a method, device, equipment and storage medium for handling fogging of vehicle windows, wherein the method includes the steps of: collecting the temperature inside and outside the vehicle, the humidity inside and outside the vehicle, and the light transmittance of the vehicle windows; judging the location of the fogging source based on the current region, driving environment, the temperature inside and outside the vehicle, the changes in the humidity inside and outside the vehicle, and the light transmittance of the vehicle windows; and implementing the corresponding defogger strategy in advance according to whether the fogging source is inside or outside the vehicle. When the vehicle is driving in an environment with high humidity or a large temperature difference between indoor and outdoor environments, the poor vision is caused by fogging, and the source of fogging can be effectively judged, and the cause of the abnormal driving vision can be informed to the driver, and operational countermeasures can be prompted to restore the driving vision as soon as possible, ensure driving safety, and avoid accidents. In addition, the indoor and outdoor humidity can be monitored in real time to prevent the "fogging" phenomenon, control the humidity inside the vehicle, and reduce the probability of fogging in areas with heavy rain to avoid the growth of mold and a poor driving environment.

[0072] Reference Figure 2 , Figure 2 FIG. 1 is a schematic diagram of a vehicle window fogging treatment device provided by the present invention, such as Figure 2 As shown, the device comprises:

[0075] Execution module 203: It is used to implement the corresponding defogging strategy in advance according to the location of the fog source.

[0076] Furthermore, in a possible implementation manner, the judgment module is also used to

[0077] If the vehicle is in an underground parking lot, if the temperature inside the vehicle is greater than the outside temperature, there is a user in the vehicle, and the window transmittance is less than a threshold, then it is determined that the source of fogging is inside the vehicle;

[0078] If the vehicle is currently in the first preset area, it is detected that there is a user in the vehicle, the humidity inside the vehicle is greater than the humidity outside the vehicle, and the light transmittance of the window is less than a 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 detected to be lower than the outside temperature, the outside humidity is higher than the humidity inside the vehicle, and the window transmittance is lower than the threshold, it is determined that the source of fogging is outside the vehicle;

[0080] If the vehicle is in a foggy and humid driving environment, if the outside temperature is greater than the inside temperature, the outside humidity is greater than the inside humidity, and the window transmittance is less than a threshold, it is determined that the fogging source is outside the vehicle;

[0081] If the vehicle is in an open-air driving environment, and the outside humidity is detected to be lower than the humidity inside the vehicle, the outside temperature is lower than the temperature inside the vehicle, and the window transmittance is lower than a threshold, it is determined that the source of fogging is inside the vehicle.

[0082] Furthermore, in a possible implementation manner, the judgment module is further configured to judge that the glass inside the vehicle has a tendency to fog if the detected temperature inside the vehicle changes from low to high relative to the humidity and temperature outside;

[0083] If the detected temperature inside the vehicle changes from high to low relative to the outside humidity and temperature, it is determined that the exterior glass of the vehicle has a tendency to fog.

[0084] Further, in a possible implementation manner, the execution module is also used for, when the vehicle is in summer, if it is determined that the glass inside the vehicle has a tendency to fog, turning on the vehicle A / C switch in advance and adjusting the temperature to the lowest, and turning on the internal circulation mode to prevent fogging on the glass inside the vehicle;

[0085] When the vehicle is in winter, if it is determined that the interior glass has a tendency to fog up, turn on the air conditioner in advance and adjust it to the preset temperature, or turn on the window heating function to prevent the interior glass from fogging up;

[0086] If it is determined that the exterior glass of the vehicle has a tendency to fog, the front windshield will be wiped, the rearview mirror will be heated, and the glass on both sides of the door will be circulated internally to prevent fogging on the exterior glass.

[0087] Furthermore, in a possible implementation manner, the judgment module is further configured to use a haze detection sensor to detect whether the clarity of the vehicle glass meets the standard if the defogging strategy is released in advance;

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

[0089] Furthermore, in a possible implementation manner, 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.
