[0050] Here, exemplary embodiments will be described in detail, and examples thereof are shown in the accompanying drawings. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0051] When there is an obstruction on the vehicle glass, at least one of the multiple clearing devices matching the obstruction information is controlled according to the vehicle environment information to perform an operation of clearing the obstruction;

[0052] The obstruction information includes at least one of an obstruction type, an obstruction area, and an obstruction position;

[0053] And / or, the plurality of cleaning devices include at least one of a transparent heating film, a vehicle air conditioner, and a wiper.

[0054] The method controls a plurality of clearing devices to perform clearing operations suitable for at least one of the current obstruction position, obstruction type, and obstruction area through vehicle environment information of the vehicle in combination with obstruction information, so as to realize vehicle adaptive clearing of obstructions.

[0055] Vehicle glass includes the front windshield of the vehicle and also includes the side windows of the driver's seat. Frost, snow, fog, water droplets and other obstructions may block the driver's sight, thereby affecting driving safety. The front windshield is used as an example for explanation in the embodiment, and the side windows of the driver's seat are the same.

[0056] Normally, there is no vehicle adaptive clearing method and device. During driving, if there are obstructions such as frost, snow, fog, water droplets, etc. blocking the driver's driving vision, affecting driving realization or even making it difficult to see the road conditions, the driver can only judge whether there is frost or fog on the windshield based on his intuitive perception of the environment, and then turn on the car air conditioner, wipers or transparent heating film for defogger and defrost. The driver cannot feel the temperature outside the car, and the accuracy of judging whether there is frost or fog on the windshield is low. During road driving, the road conditions are very complicated. If the driver cannot distinguish between water mist and frost, or makes a wrong judgment whether it is fog inside the car or fog outside the car, or mistakenly turns on the car air conditioner for defrosting when there is frost outside the car, it may cause the driver to panic, seriously affecting the safety of vehicle driving. While driving on the road, the road conditions are very complicated. If the driver accurately identifies the shape and position of frost, snow, fog, water droplets, etc., he also needs to lower his head to turn on the wipers, car air conditioner or transparent heating film. Calculated based on the average speed of 65 kilometers per hour on urban roads, a small action of lowering the head to turn on the switch takes an average of about 1-4 seconds. Taking the attention away from the road for 4 seconds is equivalent to driving 72 meters with your eyes closed. In real life, there are countless traffic accidents caused by distracted drivers.

[0057] Usually, a single cleaning device is used, such as a single transparent heating film or a single car air conditioner. The heating efficiency of the car air conditioner is relatively low. When the ice and snow on the front windshield are thick in winter, it takes too long. If the defrosting is still done by air conditioning heating in the hot and humid summer, it will inevitably increase the temperature inside the car and reduce the user's driving experience. Although the thermal efficiency of the transparent heating film is high and will not increase the temperature inside the car, it has no dehumidification function. If the high-efficiency transparent heating film is turned on when the windshield is slightly fogged, it will cause energy waste. The car air conditioner relies on the refrigeration system to reduce the temperature inside the car, so that the water vapor in the car condenses into water, thereby reducing the absolute humidity in the car. This means that the air conditioner cannot dehumidify while heating and defrosting. That is, it is difficult for a single heating tool, such as a transparent heating film or a car air conditioner, to perform both defrosting and dehumidification functions at the same time, and it is difficult to balance the difficulty of defrosting and defogging with user comfort. In addition, there is no alternative plan for the single heating tool defrosting technology. When the heating tool malfunctions, the user can only consume his own physical strength and find other methods in bad weather, such as warm water compress, scrape with cardboard, wipe with a rag, sweep with a broom, etc., which is time-consuming and labor-intensive.

[0058] At least one of the clearing devices is turned on to adapt to the current vehicle environment information and obstruction information to ensure that the turned-on clearing device clears obstructions in the best manner. In other words, the vehicle adaptive clearing method provided in this embodiment can realize adaptive clearing of obstructions.

[0059] Normally, the car air conditioner can be used to blow the front windshield in a directional manner to dehumidify and defog. The car air conditioner can blow cold air to reduce the temperature difference between the inside and outside of the car, or it can blow hot air to reduce the humidity in the car and effectively remove the fog in the car. The transparent heating film is mainly made of transparent PET and other materials. It can be well used in objects that require high transparency and temperature control. The heating function of the transparent heating film can effectively prevent frost and snow accumulation and maintain good visibility of the front windshield. The transparent heating film maintains a constant temperature during use, so that the front windshield can maintain good visibility even under low temperature conditions, which will not affect driving safety. The wiper is used to remove raindrops on the outside of the vehicle glass in rainy and foggy weather. And timely and quickly remove the obstructions on the vehicle glass to ensure the cleanliness of the vehicle glass and ensure driving safety.

[0060] This embodiment can adaptively select at least one of a plurality of clearing devices that matches at least one of the type, position, and area of ​​the obstruction to perform the obstruction clearing operation according to the vehicle environment information. This embodiment uses a variety of clearing devices, which cooperate with each other to perform defrosting and defogging operations. Compared with a single clearing tool, it can simultaneously realize multiple clearing functions, such as defrosting and dehumidifying functions, and can also better balance the difficulty of clearing obstructions and user comfort. The driver does not need to lower his head to turn on the corresponding clearing device switch, which helps to improve driving safety.

[0061] In one embodiment, the position of the obstruction includes at least one of information about the inside and outside of the vehicle glass and information about the area of ​​the obstruction on the vehicle glass.

[0062] It is understandable that the obstruction is located on the vehicle glass. Usually, the vehicle glass is transparent, and it is difficult to distinguish whether the obstruction is located on the inside or outside of the vehicle glass. If the obstruction is located on the inside of the vehicle, the vehicle air conditioner or transparent heating film can be turned on to remove the obstruction. At this time, if the wiper is turned on, the obstruction cannot be removed. Similarly, when the obstruction is located on the outside of the vehicle, it can be cleaned by turning on the transparent heating film or wiper, but the vehicle air conditioner is difficult to effectively remove the obstruction, and its removal effect is unsatisfactory.

[0063] In addition, the regional position of the obstruction on the vehicle glass is also related to the selection of the cleaning device. Specifically, if the obstruction is located at the front windshield, rearview mirror, or other locations that affect the driver's driving safety, a higher-power cleaning device is needed to remove it as soon as possible. If the obstruction is located at the side window glass of the rear seat, it will have a lower impact on the driver's driving safety. The in-car temperature adjustment device can be reused to remove it, or a lower-power cleaning device can be used to remove it. Furthermore, taking the front windshield as an example, when the obstruction is located in front of the main driving seat of the front windshield, blocking the driver's line of sight, it is necessary to remove the obstruction as soon as possible to ensure that the driver's field of vision is wide and bright, and to improve the driving safety of the driver and passengers. If the obstruction is located at the edge of the vehicle glass, or the co-pilot seat, and does not affect the driver's field of vision, a lower-power cleaning device can be turned on for cleaning.

[0064] In one embodiment, the vehicle environment information is used to indicate information about whether an obstruction is inside or outside the vehicle glass.

[0065] Specifically, according to the environment in which the vehicle is located, such as the temperature and humidity inside and outside the vehicle, it can be indicated whether the obstructions such as frost or fog are on the inside or outside of the vehicle glass according to the temperature difference and humidity inside and outside the vehicle, and then the corresponding removal device can be controlled to clean the obstructions. For example, the frost or fog inside the car can be removed by the car air conditioner inside the car or the transparent heating film on the vehicle glass. The frost or fog outside the car can be removed by the wiper or the transparent heating film on the vehicle glass. When there is frost or fog in the car, using wipers will not help. Similarly, when there is frost or fog outside the car, the heat of the car air conditioner can be slowly conducted to the outside of the glass through the vehicle glass to remove the frost and fog, but the effect is unsatisfactory.

[0066] In one embodiment, the vehicle environment information includes at least one of the temperature inside the vehicle, the temperature outside the vehicle, the humidity inside the vehicle, and the humidity outside the vehicle.

[0067] Specifically, by comparing the temperature inside the car with the temperature outside the car, it is possible to roughly determine whether it is fogging or frosting. Furthermore, by combining the humidity inside or outside the car, it is possible to more accurately determine whether it is frosting or fogging inside the car or frosting or fogging outside the car.

[0068] In addition, human comfort is mainly determined by two factors: ambient temperature and humidity. Therefore, ambient temperature and humidity can also determine the comfort of the driver and passengers. When selecting a variety of cleaning devices, the comfort of the driver and passengers can be comprehensively considered. Scientific research shows that when the temperature is in the range of 18-25℃ and the humidity is in the range of 40-70%, the human body feels most comfortable. When the temperature is in the range of 25-30℃ and the humidity is less than 60%, people will feel hot but not stuffy. When the temperature is greater than 30℃ and the humidity is higher than 70%, people will feel stuffy.

[0069] Preferably, the temperature of the present application is 20-25°C and the humidity is 40-60%.

[0070] Optionally, when the car is foggy, the car air conditioner can be used for defogger. If the car air conditioner is dehumidifying, it means that the temperature inside the car is greater than the temperature outside the car, and the humidity inside the car is greater than or equal to the preset value. At this time, the temperature inside the car is relatively high. Considering the driving comfort of the user, a transparent heating film can be used to defog the car.

[0071] Optionally, when fog appears in the car, because the fog is formed by the condensation of water vapor suspended in the atmosphere, it means that the humidity in the car needs to be higher than a preset value. If the car air conditioner is not turned on for dehumidification, and the temperature outside the car is higher than the temperature inside the car, the fog in the car can be heated and defogged by the car air conditioner. Since the temperature outside the car is higher than the temperature inside the car, even if the car air conditioner is heated, it will not affect the physical sensation of the driver and passengers.

[0072] Optionally, when frost forms inside or outside the vehicle, the transparent heating film can be used to melt the frost as quickly as possible. After the frost outside the vehicle melts into water, it can be cleaned by a windshield wiper. After the frost inside the vehicle melts, it can be cleared by the vehicle air conditioner.

[0073] In one embodiment, the types of obstructions include at least one of frost, snow, fog, and water droplets. Generally, obstructions on vehicle glass may be foreign matter such as dust, or may be obstructions caused by sudden weather. For example, foreign matter such as dust is accumulated during long-term storage, and is easy to detect and clean when the vehicle starts. Generally, it is removed before the vehicle starts. However, obstructions caused by weather are unpredictable and difficult to control during driving. The driving environment is complicated, and the driver and passengers need to concentrate. Tiny foreign matter will affect driving safety. Therefore, the types of obstructions in this embodiment include at least one of frost, snow, fog, and water droplets. The types of obstructions are caused by weather reasons. If the temperature is low, it may be frost or snow. Since frost and snow are both forms of ice, hail or other water condensation caused by the weather can be considered as frost.

[0074] In one embodiment, when there is an obstruction on the vehicle glass, before at least one of the plurality of cleaning devices performs a cleaning operation, the method further comprises:

[0075] The obstruction information of the vehicle glass is obtained according to the image information of the vehicle glass.

[0076] Specifically, the image information of the vehicle glass can be used to indicate the information of the obstruction. The obstruction can be photographed by a camera, or it can be identified by sensors and other means whether there is an obstruction on the vehicle glass. When there is an obstruction on the vehicle glass, a matching clearing device is selected to perform the obstruction clearing operation based on the vehicle environment information and the obstruction information.

[0077] Optionally, this embodiment takes the front windshield as an example to obtain the image information of the windshield. Usually, a camera is used to collect the image information of the windshield. In order to ensure that the camera can completely capture the entire front windshield, two wide-angle cameras can be installed on the A-pillar of the vehicle, near the upper left corner and the upper right corner of the front windshield. The A-pillar refers to the pillars on both sides of the front windshield, located between the engine compartment and the passenger compartment. The two wide-angle cameras are used to determine whether the front windshield is foggy or frosty, and to identify whether the sight lines of the driver's seat and the co-pilot's seat are blocked. When the vehicle clear switch is turned on, the camera will continue to monitor the frost and fogging on the front windshield.

[0078] The camera collects the image information of the vehicle glass. The image information is used to indicate the obstruction information of the vehicle glass. The obstruction information includes the type of obstruction and the area of ​​the obstruction. The type of obstruction can be solid or liquid. If the obstruction type is solid, it indicates that there is frost or snow on the vehicle glass. When the obstruction type is liquid, there is fog or water droplets on the vehicle glass. Solid obstructions are more difficult to remove than liquid obstructions. If the vehicle air conditioner is used for defrosting, the heating efficiency of the air conditioner is relatively low and it takes a long time. A transparent heating film can be used to improve the efficiency of heating and defrosting.

[0079] Furthermore, the image information can also indicate the size of the obstruction area. Specifically, the obstruction area can be the ratio of the obstruction to the area of ​​the entire vehicle glass. If the obstruction area is large, it will seriously affect the driver's driving safety during driving, and the frost or fog on the vehicle glass needs to be quickly removed. Considering that the heating efficiency of transparent heating film is higher, it is more inclined to use transparent heating film for defrosting and defog.

[0080] The image information may also indicate the location of the obstruction, which may be the location of the obstruction on the vehicle glass, or the brightness of the obstruction in the image information may indicate whether the obstruction is inside or outside the vehicle.

[0081] In one embodiment, if Figure 1 As shown, the occlusion information includes the occlusion type,

[0082] If the type of obstruction includes a condensation obstruction, the vehicle air conditioner and the transparent heating film perform an operation of clearing the obstruction;

[0083] If the type of obstruction includes a liquid obstruction, at least one of the vehicle air conditioner, the transparent heating film, and the wiper performs an operation of clearing the obstruction.

[0084] Specifically, considering the difficulty of removing obstructions, it is more difficult to remove condensation obstructions. Using wipers to remove condensation obstructions may cause damage to the wipers. Condensation obstructions are snow, frost, etc., and the defrosting and snow removal operations can be performed by preferentially controlling the transparent heating film to improve the efficiency of defrosting and snow removal. If the thickness of the condensation obstruction is thin, or the area of ​​the condensation obstruction is small, the melting of condensation obstructions such as frost and snow can also be promoted by heating the vehicle air conditioner. Using a lower-power vehicle air conditioner instead of a higher-power transparent heating film can also help save energy. In general, when frost and snow appear on the vehicle glass, the temperature is low. Usually, in order to improve comfort, the driver and passengers will also turn on the vehicle air conditioner to increase the temperature inside the vehicle. When the thickness of the condensation obstruction is thin, or the area of ​​the obstruction is small, the vehicle air conditioner can not only improve the comfort of the driver and passengers, but also help to remove the obstruction on the vehicle glass. The reuse of heat is also conducive to energy saving.

[0085] When the types of obstructions include liquid obstructions, such as fog or water droplets, the obstruction removal operation can be performed through the wiper and the vehicle air conditioner. It is understandable that when the liquid obstruction is on the outside of the vehicle glass, the wiper can be used to remove the fog or water droplets on the outside. When the liquid obstruction is on the inside of the vehicle glass, the vehicle air conditioner can be used to heat or cool it to achieve the effect of quickly removing the obstruction. If the vehicle is heavily fogged, the transparent heating film can be used to quickly remove the obstruction to ensure that the vehicle glass is clean and improve driving safety.

[0086] In one embodiment, the hydrocondensation obstruction includes at least one of frost or snow; and / or the liquid obstruction includes at least one of fog or water droplets.

[0087] Specifically, if there is snow on the outside of the vehicle glass and frost inside the vehicle, the snow on the outside can be cleared with a transparent heating film, and the frost inside the vehicle can reuse the heat of the transparent heating film to help melt it. Considering that after the frost in the car melts into water, the water will slide irregularly and affect the driver's line of sight, it is necessary to turn on the car's air conditioner to blow away the water melted from the frost as soon as possible.

[0088] Similarly, when the liquid obstruction includes at least one of fog and water droplets, for example, when it is raining heavily outside the car and the car is foggy, the wipers can be turned on to clear the rain on the outside of the vehicle glass. At the same time, the car air conditioner can be turned on to defog to ensure the cleanliness of the vehicle glass and improve driving safety.

[0089] In one embodiment, the obstruction information includes the area of ​​the obstruction, and according to the ratio of the area of ​​the obstruction to the area of ​​the entire vehicle glass being greater than a first threshold, the vehicle air conditioner and the transparent heating film perform an operation of clearing the obstruction;

[0090] If the ratio of the area of ​​the obstruction to the area of ​​the entire vehicle glass is less than a first threshold, the vehicle air conditioner performs an operation of clearing the obstruction.

[0091] It is understandable that if the area ratio η of the obstruction to the area of ​​the entire vehicle glass is greater than the first threshold, it indicates that frost and fogging seriously affect the driver's driving vision, and defrosting and defogging need to be performed in time to improve driving safety. In addition, considering the difficulty of clearing obstructions, the difficulty of defrosting and defogging is also related to the size of the area of ​​the sight obstruction. Specifically, if the area ratio of the obstruction to the area of ​​the entire vehicle glass is greater than the first threshold, if the obstruction affects the driver's line of sight, the transparent heating film can be controlled to defrost and defog, which can speed up the efficiency of clearing the obstruction; in addition, if the obstruction does not affect the driver's line of sight, it can be considered to use a less efficient vehicle air conditioner to remove the obstruction.

[0092] If the ratio η of the area of ​​the obstruction to the area of ​​the entire vehicle glass is less than a first threshold, the vehicle air conditioner performs an operation of clearing the obstruction. When the area of ​​the obstruction is small, it is less difficult to clear it, and the vehicle air conditioner can be used to clear the obstruction, which helps save resources on the basis of effectively clearing the obstruction.

[0093] The first threshold is used to indicate the minimum area of ​​the driver's vision blocked by obstructions during driving to affect driving safety. Optionally, the numerical range of the first threshold can be [0.2, 1], 0.2≤first threshold≤1. For example, when the first threshold is 0.5, the ratio of the area of ​​the obstruction to the area of ​​the entire vehicle glass is greater than 0.5, and the vehicle air conditioner and the transparent heating film perform the operation of clearing the obstruction; if the ratio of the area of ​​the obstruction to the area of ​​the entire vehicle glass is less than 0.5, the vehicle air conditioner performs the operation of clearing the obstruction.

[0094] In one embodiment, the obstruction information includes the obstruction position, and the obstruction position includes the regional position information of the obstruction on the vehicle glass.

[0095] If the obstruction is located in the first area, the transparent heating film performs an operation of clearing the obstruction;

[0096] If the obstruction is outside the first area, the vehicle air conditioner performs the operation of clearing the obstruction;

[0097] The first area is the driver's field of vision.

[0098] It is understandable that during driving, the traffic road surface is complicated, and ensuring that the driver's vision is clear and broad is related to vehicle safety. If there are obstructions on the vehicle glass that affect the driver's field of vision, the obstructions need to be removed quickly and in a timely manner to ensure that the driver can accurately and timely observe the driving environment. Therefore, when the obstruction is within the driver's field of vision, a transparent heating film can be used to remove the obstruction to improve driving safety. When the obstruction is outside the driver's field of vision and does not affect driving safety, it can be removed with the vehicle air conditioner, which not only ensures driving safety, but also helps save energy.

[0099] In one embodiment, the vehicle environment information includes the temperature inside the vehicle. When the temperature inside the vehicle is higher than a second threshold, and / or the vehicle environment information includes the humidity inside the vehicle and the humidity inside the vehicle is higher than a third threshold, the transparent heating film performs the operation of clearing the obstruction. Since human comfort is related to the temperature and humidity of the environment, when the temperature inside the car is higher than the second threshold, the second threshold may be the most comfortable temperature perceived by the human body. For example, the second threshold is 25°C. When the temperature inside the car is higher than the most comfortable temperature perceived by the human body, if it is necessary to turn on the vehicle air conditioner for heating and defrosting and defogging, it will affect the driving experience of the driver and passengers. At this time, the transparent heating film is controlled to defrost and defog so that the driver and passengers can maintain a comfortable driving experience. Similarly, the humidity inside the car will also affect the comfort experienced by the driver and passengers. If the humidity inside the car is high, and the vehicle air conditioner is turned on for heating, defrosting and defogging, the temperature inside the car will be increased, which will make the driver and passengers feel stuffy and reduce the driver and passengers' experience. Optionally, the third threshold may be the most comfortable humidity experienced by the human body. For example, the third threshold may be 60%. When the humidity inside the car is greater than 60%, the transparent heating film may be turned on for defrosting and defogging to improve the driving comfort of the driver and passengers.

[0100] In one embodiment, the vehicle environment information includes the temperature inside the vehicle and the temperature outside the vehicle. When the temperature inside the vehicle is greater than the temperature outside the vehicle and the humidity inside the vehicle is greater than or equal to a preset value, the vehicle air conditioner performs dehumidification.

[0101] like Figure 2 As shown, when there is an obstruction on the vehicle glass, by comparing the temperature inside and outside the car, it can be roughly determined whether the obstruction is inside or outside the car. When the temperature inside the car is higher than that outside the car and the humidity inside the car is also high, the temperature inside the vehicle glass is higher and the temperature outside the vehicle glass is lower. The water vapor inside the car condenses into water droplets when it encounters the vehicle glass, which easily forms fog. In order to prevent fogging before it occurs and reduce the probability of fogging inside the car, you can turn on the car air conditioner to reduce the temperature inside the car to a level close to the temperature outside the car. Due to the low temperature difference between the inside and outside of the car, water will not condense on the vehicle glass. You can also use the car air conditioner to heat the car to reduce the humidity inside the car and reduce the generation of fog.

[0102] The preset value refers to the minimum humidity at which fogging occurs in the car under the current temperature conditions when there is a temperature difference between the inside and outside of the car. The preset value will vary depending on the size of the temperature difference between the inside and outside of the car. A high humidity in the car means that there is more water vapor in the car. When the water vapor encounters the windshield, due to the temperature difference between the inside and outside of the car, the water vapor in the car will condense to form small water droplets when it encounters the windshield, causing the glass surface to reach the dew point, thereby condensing and fogging. The humidity in the car usually comes from the passengers' breathing, the evaporation of the skin, and the evaporation of wet objects.

[0103] When the front windshield is fogged, it can be quickly defogged by reducing the humidity inside the car or reducing the temperature difference between the inside and outside of the car. Optionally, open the window for ventilation, maintain proper air flow, let the humid air flow out of the car, and introduce drier air; Optionally, turn on the cooling function of the car air conditioner and direct the wind toward the front windshield, which helps to reduce the temperature inside the car, reduce the temperature difference between the inside and outside of the car, and reduce the possibility of fogging; Optionally, turn on the heating system of the car air conditioner to reduce the humidity inside the car to reduce the possibility of fogging. During road driving, opening the window for ventilation may reduce the driving comfort of the driver or other passengers. Normally, by directing the wind toward the front windshield and turning on the air conditioner to cool the car to reduce the temperature difference between the inside and outside of the car, or turning on the car air conditioner to heat to reduce humidity and reduce the possibility of fogging, the car air conditioner prevents fogging in the car from affecting the vision of the driver and passengers.

[0104] In one embodiment, if Figure 3 As shown, the various cleaning devices include: vehicle air conditioning, transparent heating film, specifically:

[0105] If the vehicle air conditioner is dehumidifying, the transparent heating film removes the obstruction;

[0106] If the car air conditioner does not dehumidify, remove the obstruction of the car air conditioner.

[0107] It is understandable that the various removal devices are coordinated with each other. When the temperature and humidity in the car are high, the car air conditioner can dehumidify to prevent fogging in the car. If there are liquid water droplets on the vehicle glass, the transparent heating film can also be turned on for rapid defrosting and defogging. In other words, when fogging occurs in the car, both the car air conditioner and the transparent heating film can be turned on for defogging. In addition, if there is no fogging in the car and the car air conditioner is not turned on for dehumidification, the car air conditioner can also be used for dehumidification to prevent the occurrence of fog.

[0108] like Figure 2 As shown, in one embodiment, the clearing device includes a wiper, and the vehicle environment information includes the temperature inside the vehicle and the temperature outside the vehicle. When the temperature inside the vehicle is lower than the temperature outside the vehicle, and when the type of the obstruction includes a liquid obstruction, the wiper performs an operation of clearing the obstruction. It can be understood that when the water on the vehicle glass is in liquid form and the temperature inside the vehicle is lower than the temperature outside the vehicle, it indicates that the outside of the vehicle glass is fogged. At this time, the wiper can be used to quickly clear the fog or other water droplets on the outside of the front windshield, and the defogging speed is fast and the defogging effect is good.

[0109] When there is an obstruction on the outside of the vehicle, such as ice, frost, or snow, and the obstruction on the outside of the vehicle glass is solid, using a windshield wiper to clear it may damage the wiper. A transparent heating film can be used to clear it.

[0110] In one embodiment, when an obstruction on the vehicle glass is cleared, at least one of the clearing devices performs an operation to prevent the obstruction from being generated.

[0111] Specifically, there are two situations in which there are no obstructions on the vehicle. One is that the temperature difference in the environment where the vehicle is located is low, or the humidity is not high, so the vehicle glass has not yet formed obstructions, such as frost or fog. The vehicle air conditioner and transparent heating film can be used to prevent the formation of frost or fog. The second is that the vehicle has used the vehicle adaptive clearing method, and the clearing device has performed the obstruction clearing operation, and after clearing it, the corresponding prevention mode can be turned on to prevent obstructions, such as frost, snow, fog, and water droplets from accumulating to block the line of sight through the vehicle air conditioner and transparent heating film.

[0112] Furthermore, if the temperature difference between the inside and outside of the car is large, the temperature inside the car is higher than the temperature outside the car, and the lower temperature outside the car makes the vehicle glass tend to frost, the transparent heating film can be turned on for heating to prevent frost on the vehicle glass.

[0113] In a second aspect, the present application provides an electronic device, comprising a memory and a processor, wherein the processor is configured to execute program instructions stored in the memory to implement any of the above vehicle adaptive clearing methods.

[0114] In a third aspect, the present application provides a vehicle adaptive clearing system, the vehicle adaptive clearing system comprising the electronic device provided above.

[0115] In one embodiment, if Figure 4 As shown, the vehicle adaptive clearing system includes a temperature sensor and a humidity sensor. The temperature sensor is used to detect the temperature inside the vehicle and the temperature outside the vehicle; the humidity sensor is used to detect the humidity inside the vehicle and the humidity outside the vehicle.

[0116] Specifically, the vehicle environment information includes the temperature inside the vehicle, the temperature outside the vehicle, the humidity inside the vehicle, and the humidity outside the vehicle. The vehicle environment information can be used to indicate the information of the obstruction. The temperature and humidity inside and outside the vehicle are used to indicate the position of the obstruction. The vehicle adaptive clearing system includes a temperature sensor and a humidity sensor. The temperature sensor is used to detect the temperature inside and outside the vehicle; the humidity sensor is used to detect the humidity inside and outside the vehicle; the temperature inside the vehicle, the temperature outside the vehicle, the humidity inside the vehicle, and the humidity outside the vehicle are used to indicate the position of the obstruction.

[0117] Temperature sensors and humidity sensors can provide more accurate detection performance.

[0118] In one embodiment, the vehicle adaptive clearing system includes an image collector, and the image collector is used to obtain image information.

[0119] It is understandable that whether there are obstructions on the vehicle glass, such as frost, snow, fog or water droplets, can be identified through image information obtained by an image collector, and the image collector can be a camera, such as a fisheye camera, a wide-angle camera, etc. The image information is used to indicate whether there are obstructions on the vehicle glass, and also includes the type of obstruction, the area of ​​the obstruction, etc. The image information of the vehicle glass can be collected by installing an image collector near the vehicle glass, and the image information of the vehicle glass can be collected in real time. The type of obstruction, whether it is solid frost, snow or liquid fog or water droplets, and the area of ​​the obstruction can be reflected in real time through the vehicle glass image information. By comprehensively considering the type of obstruction and the area of ​​the obstruction, the most suitable removal device for the current environment can be turned on to clear the obstruction, so as to remove the obstruction as soon as possible and improve the driving safety performance.

[0120] The temperature sensor, humidity sensor and image collector can be collectively referred to as a data acquisition module, which is used to collect vehicle environment information and obstruction information to assist the subsequent controller to adaptively activate at least one of the most matching removal devices. The data acquisition module can collect corresponding data in a timely and accurate manner to ensure that the selected removal device can both meet the difficulty of clearing obstructions and improve the comfort of drivers and passengers.

[0121] The execution module may be a clearing device. Optionally, the execution module includes at least one of a vehicle air conditioner, a transparent heating film, and a wiper.

[0122] In one embodiment, the vehicle adaptive clearing system further includes a clearing switch, which includes at least one of a vehicle button, a vehicle central control screen, and a mobile phone application. It is understandable that the vehicle adaptive clearing system can be turned on by a vehicle button, a vehicle central control screen, or a mobile phone application, and the clearing switch can be a vehicle button on the vehicle. With the development of intelligence, the vehicle central control screen or the mobile phone application can also control the vehicle to turn on the clearing switch.

[0123] After the execution module has executed the operation of clearing the obstruction and the obstruction has been cleared, the central control screen, mobile phone application, or other speaker devices in the car will make a voice broadcast to inform the driver and passengers that the obstruction has been cleared, and remind the driver and passengers to choose whether to turn off the adaptive clearing function or turn on the energy-saving mode. The energy-saving mode can dehumidify to prevent fogging and frost.

[0124] In a fourth aspect, the present application provides a computer-readable storage medium having program instructions stored thereon, and when the program instructions are executed by a processor, the above-mentioned vehicle adaptive clearing method is implemented.

[0125] In a fifth aspect, the present application provides a vehicle comprising the electronic device described above.

[0126] After the above vehicles turn on the vehicle adaptive clearing system, the image collector collects image information of obstructions on the vehicle glass. The obstruction information includes, for example, the type of obstruction and the area of ​​the obstruction. The temperature sensor and humidity sensor are used to monitor the humidity and temperature conditions inside and outside the vehicle. The position of the obstruction is judged according to the image information on the vehicle glass and the temperature and humidity conditions inside and outside the vehicle. Taking into account the comfort experience of the driver and passengers, the most suitable clearing device is adaptively selected for cleaning. There is no need for manual judgment and processing based on experience, which helps to improve driving safety.

[0127] Regarding the device in the above embodiment, the specific manner in which each module performs operations has been described in detail in the embodiment of the method, and will not be elaborated here.

[0128] The preferred embodiments of the present application are described in detail above in conjunction with the accompanying drawings; however, the present application is not limited to the specific details in the above embodiments. Within the technical concept of the present application, a variety of simple modifications can be made to the technical solution of the present application, and these simple modifications all fall within the protection scope of the present application.

[0129] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this application will not further describe various possible combinations.

[0130] In addition, the various implementation modes of the present application may be arbitrarily combined, and as long as they do not violate the concept of the present application, they should also be regarded as the contents disclosed in the present application.
