When the car window glass is in a scene with temperature difference, it is very easy to form fog and adhere to the car window glass, which will affect the driver's vision and endanger driving safety. Although the driver can start the car air conditioner to achieve defogger, this method will distract the driver's attention, not only the defogger effect is not ideal, but also brings certain safety hazards.

In one embodiment, as shown in FIG1 , a vehicle window defog control method is provided, and the method is described by taking the application of the method to a vehicle as an example, including the following steps:

Step 101, obtaining environmental information, wherein the environmental information includes in-vehicle environmental information and out-vehicle environmental information.

Specifically, the environmental information can be obtained through sensors installed on the vehicle, or the external environmental information can be obtained through networking.

Step 102: determine whether the vehicle windows have reached a fogging condition based on the vehicle interior environment information and the vehicle exterior environment information.

Among them, the fogging condition refers to the threshold (critical value) when water vapor in the air condenses into water droplets on the car window glass.

Specifically, when the air humidity and the temperature difference between the inside and outside of the vehicle reach a certain threshold, fog may form on the inside or outside of the vehicle window glass. Therefore, whether fogging is possible can be determined based on the inside and outside environment information.

Step 103: If yes, the environmental information is adjusted through a temperature control method, and the window information of the vehicle window is detected, and the temperature control method is controlled accordingly according to the window information.

Among them, the temperature control method refers to a method of controlling temperature, which prevents the car windows from fogging up. The temperature control method can be to adjust the temperature of the car interior and/or the windows by activating the car air conditioner, and/or there is a temperature control device that can control the temperature of the car window glass, such as heating or cooling the windows.

Specifically, when adjusting environmental information through temperature control, it is also necessary to detect the window information of the vehicle windows and control the temperature control method according to the window information, so that the temperature control method can be adaptively adjusted according to the real-time window information, and it can also prevent the temperature control method from being executed for too long, reducing the durability of the window glass.

In the above-mentioned vehicle window defogger control method, by acquiring environmental information, it is possible to determine whether the vehicle window has reached the fogging condition according to the vehicle interior environmental information and the vehicle exterior environmental information. If the fogging condition has been reached, the environmental information can be adjusted by temperature control to prevent the vehicle window from fogging. At the same time, the vehicle window information of the vehicle window is detected, and the temperature control method is controlled accordingly according to the vehicle window information, so that the vehicle window defogger process can be more effectively controlled. The vehicle window can be defogged effectively by the above-mentioned vehicle window defogger control method.

In one embodiment, it also includes:

Comparing the environmental information with the fogging threshold to obtain a comparison result, and judging whether the vehicle window reaches the fogging condition according to the comparison result, wherein the environmental information includes humidity information and temperature information, and the fogging threshold includes a humidity threshold and a temperature difference threshold;

When the vehicle window reaches the fogging condition, the environmental information is adjusted.

The fogging threshold is a fogging condition. When the vehicle interior and exterior environment information reaches the condition corresponding to the fogging threshold, the vehicle window glass may fog up.

Specifically, the temperature difference between inside and outside the vehicle is calculated based on the temperature information to obtain the temperature difference information, the humidity information is compared with the humidity threshold, and the temperature difference information is compared with the temperature difference threshold to obtain a comparison result, and whether the vehicle window reaches the fogging condition is determined based on the comparison result. If so, the environmental information is adjusted.

Preferably, relative humidity can be calculated through humidity information, wherein relative humidity refers to the percentage value of the actual water vapor content in the air (absolute humidity) to the saturated humidity (maximum possible water vapor content) at the same temperature. If the relative humidity reaches a humidity threshold (e.g. 100%), it proves that the water vapor in the air exceeds the saturation amount and has reached a saturated state, and may condense into water droplets, i.e., fog.

In one embodiment, it also includes:

Get real-time car window images;

Comparing the real-time vehicle window image with a normal vehicle window image to determine whether the vehicle window is fogged;

If so, a corresponding defog scheme is selected according to the environmental information and the vehicle window image to defog the vehicle window.

The normal window image is the image information when the window is not fogged, which can be pre-stored or obtained through the Internet.

Specifically, the real-time window image is compared with the normal window image to determine whether the window is fogged. If so, it is necessary to determine whether the fog is on the inside or outside of the window based on environmental information, and select the corresponding defogger solution to defog the window.

It is understandable that fogging is usually caused by hot air coming into contact with cold glass, which results in fogging on the glass. Depending on the environmental information, there may be two situations: fogging on the inside or fogging on the outside.

In one embodiment, it also includes:

comparing the humidity information with the humidity threshold;

When the humidity information is greater than the humidity threshold, acquiring the temperature information, wherein the temperature information includes the ambient temperature and the cabin temperature;

Obtaining a first temperature difference according to the ambient temperature and the cabin temperature, and comparing the first temperature difference with the first temperature difference threshold;

When the first temperature difference is greater than the first temperature difference threshold, the vehicle window is temperature controlled.

Among them, the ambient temperature refers to the ambient temperature of the vehicle window, which includes the ambient temperature outside the vehicle and the ambient temperature inside the vehicle. However, in the process of fogging judgment, the ambient temperature outside the vehicle can be used as the basis for calculation and explanation, while the cabin temperature is used to indicate the temperature information inside the vehicle.

Specifically, a first temperature difference is calculated based on the ambient temperature and the cabin temperature, which is the ambient temperature difference between the inside and outside of the vehicle. The first temperature difference is compared with a first temperature difference threshold to determine whether fogging will occur under the current ambient temperature difference. If so, temperature control is performed.

In one embodiment, it also includes:

Acquiring a vehicle window temperature, and obtaining a second temperature difference according to the vehicle window temperature and the ambient temperature;

comparing the second temperature difference with the second temperature difference threshold;

When the second temperature difference is less than the second temperature difference threshold, the temperature control of the vehicle window is suspended.

Specifically, in addition to obtaining the temperature difference between the inside and outside environments of the vehicle, it is also necessary to obtain the temperature difference between the window temperature and the ambient temperature to reflect the temperature condition of the window relative to the surrounding environment, so as to more accurately control the temperature of the window.

In one embodiment, it also includes:

When the temperature of the vehicle window is controlled, the corresponding time is recorded to obtain the temperature control time;

When the temperature control of the vehicle window is suspended, the corresponding time is recorded to obtain the suspension time;

The temperature control time is compared with the pause time. When the temperature control time is greater than or equal to the pause time, the environmental information is compared with the fogging threshold to determine whether the vehicle window meets the fogging condition.

When temperature control is suspended, fogging conditions may form again. Therefore, by comparing the temperature control time and the pause time, after the temperature control time is greater than or equal to the pause time, the environmental information and the fogging threshold are compared again to determine whether the vehicle windows have reached the fogging conditions again.

In one embodiment, it also includes:

Acquire at least two vehicle window image frames in real time, wherein the vehicle window image frames include a first vehicle window image frame and a second vehicle window image frame;

Acquire first image information of the first frame vehicle window image and second image information of the second frame vehicle window image;

Determining whether the clarity of the first frame of the vehicle window image reaches a clarity threshold according to the first image information;

If yes, obtaining the change information of the first frame vehicle window image and the second frame vehicle window image according to the first image information and the second image information;

Determine whether the vehicle window is fogged according to the change information.

Among them, the first frame of the vehicle window image and the second frame of the vehicle window image are examples only for the convenience of explanation, and in fact, the number and/or acquisition conditions of the vehicle window images are not limited. It can be understood that this embodiment can also include a third frame of the vehicle window image, a fourth frame of the vehicle window image, etc., and the interval time between the first frame of the vehicle window image and the second frame of the vehicle window image is not limited to one frame.

Specifically, the collected window image is subjected to image processing, such as grayscale processing, filtering processing, edge recognition, etc., to obtain corresponding image information, wherein the image information includes pixel information, histogram information, RGB information, HSV information, etc. of the image, which will not be repeated here, and the clarity of the image can be further calculated based on the image information.

Exemplarily, the RGB image can be converted into a grayscale image through grayscale processing, and the distribution of the histogram information corresponding to the grayscale image can be used to determine whether the image has fog. It can be understood that if the image has no fog, the histogram of the grayscale image should be distributed relatively evenly.

Preferably, the image may also be converted from the RGB color space to the HSV color space, and the clarity detection may be performed using the HSV color space.

Preferably, the window image can be recognized and the clarity detected by a variety of clarity algorithms, focusing evaluation functions, etc., including Brenner function, Tenengrad gradient function, Laplacian gradient function, grayscale variance function, etc., which will not be repeated here.

When it is identified that the clarity of the first frame of the window image does not reach the clarity threshold, the current environmental information and fogging conditions are combined to determine whether the first frame of the window image at this moment is a fogged window image. If so, it is determined based on the environmental information whether the window is fogged on the inside or outside, and the corresponding defogger method (including temperature control, window cleaning, etc.) is selected according to different situations.

If it is recognized that the clarity of the first frame window image reaches the clarity threshold, the second image information of the second frame window image can be compared with the first image information of the first frame window image to obtain change information, and whether the second frame window image has changed in clarity relative to the first frame window image can be determined based on the change information. If the change information is greater than the change threshold, it may indicate that fogging has occurred during the acquisition process from the first frame window image to the second frame window image, which significantly affects the clarity of the second frame window image. Through dynamic detection, the detection of window fogging is more accurate, and the control efficiency of window defogger is further improved. Combined with the above embodiments, not only is control performed in terms of preventing window fogging, but there is also a corresponding control method to deal with it after detecting window fogging, which greatly improves the user experience of the vehicle user.

In addition, it should be noted that in the process of acquiring real-time window images, the acquired window images may be focused on the window glass or on one or more object targets outside the window, which is not limited here.

It should be understood that, although the various steps in the above flowchart are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the above flowchart may include multiple sub-steps or multiple stages, and these sub-steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these sub-steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the sub-steps or stages of other steps.
