Description

Technical Field

[0001] The present application relates to the technical field of automobile air conditioning, and in particular to a method for defrosting vehicle window glass, a vehicle, and a storage medium. Background Art

[0002] As people increasingly use their cars for travel, their demands for vehicle performance and safety are also increasing. Clear vision is crucial for safe driving. Frost on the windshield can severely impair the driver's vision, making it difficult to see road conditions, traffic signs, and other vehicles, compromising driving safety. Drivers can defrost the windshield by turning on the defrost function on the car's air conditioner.

[0003] In order to clear the frost and fog, the air conditioner operates in a high-power and high-air-volume mode, which has low efficiency and high energy consumption. Summary of the Invention

[0004] In view of this, the present application is dedicated to providing a method for defrosting vehicle window glass, a vehicle and a storage medium, which can improve the defrosting efficiency, reduce the defrosting time, and reduce the energy consumption of defrosting.

[0005] According to the first aspect of the present application, a method for defrosting vehicle windows is provided, comprising: detecting a frost fog area on the front windshield of a target vehicle; and adjusting the guide vanes at a target air outlet on the front windshield of the target vehicle so that the airflow blown out from the target air outlet is concentrated on the frost fog area. This maximizes the concentration of limited air-conditioning output energy to the local area where frost fog is truly needed, significantly improving the defrosting efficiency per unit airflow. As a result, frost fog in key visual areas can be quickly removed, effectively shortening the time required for defrosting, avoiding obstruction of the driver's vision due to frost fog blocking key visual areas, and thereby greatly reducing the driving safety risks caused by unclear vision. At the same time, by precisely controlling the direction of airflow to reduce unnecessary energy consumption, the overall energy consumption of the air-conditioning system during the defrosting process can be significantly reduced, thereby helping to improve the cruising range of pure electric vehicles or the pure electric mode cruising range of hybrid vehicles.

[0006] Optionally, adjusting the guide vanes at the target air outlet on the front windshield of the target vehicle so that the airflow blown out of the target air outlet is concentrated on the frost fog area includes: determining a target frost fog area with the highest priority from the frost fog areas; the priority corresponding to the frost fog area is positively correlated with the degree of interference of the frost fog in the frost fog area with the driver's field of vision; and adjusting the guide vanes so that the airflow is concentrated on the target frost fog area. Since the airflow has a more concentrated range of action, the overall defrosting time is further shortened, and the defrosting efficiency per unit airflow is improved, thereby further reducing the overall energy consumption of the air conditioning system during the defrosting process.

[0007] Optionally, adjusting the guide vanes to concentrate the airflow on the target frost area includes: if the target frost area exists on both the left and right sides of the front windshield, periodically adjusting the angle of the guide vanes so that the airflow alternately concentrates on each target frost area. Compared to simultaneously dispersing air across multiple areas, the alternating concentrated blowing mode delivers more focused energy to the target area, shortening defrost time and improving defrost efficiency, while also reducing the overall energy consumption of the air conditioning system during the defrost process.

[0008] Optionally, the first area is the area near the driver's seat at the center of the front windshield; the second area is the area near the passenger seat at the center of the front windshield; and when the target frost and fog areas exist on both the left and right sides of the front windshield, the angle of the guide vanes is periodically adjusted so that the airflow is alternately concentrated on each target frost and fog area, including: when both the first and second areas are target frost and fog areas, the following steps are alternately performed: cutting off the ventilation path on the side of the target air outlet near the second area, opening the ventilation path on the other side, and adjusting the angle of the guide vanes so that the airflow is concentrated on the first area; cutting off the ventilation path on the side of the target air outlet near the first area, opening the ventilation path on the other side, and adjusting the angle of the guide vanes so that the airflow is concentrated on the second area. Compared with blowing on the first and second areas simultaneously, the airflow acting on a single target frost and fog area is more concentrated, thereby further shortening the overall defrosting time and improving the defrosting efficiency per unit airflow, thereby further reducing the overall energy consumption of the air conditioning system during the defrosting process.

[0009] Optionally, when the target frost fog area exists on both the left and right sides of the front windshield, the angle of the guide vane is periodically adjusted so that the airflow alternately concentrates on each of the target frost fog areas, including: when there is no frost fog area at the center of the front windshield and the target frost fog area exists on both the left and right sides of the front windshield, all ventilation paths at the target air outlet are opened, and the angle of the guide vane is periodically adjusted so that the airflow alternately covers the left and right parts of the front windshield. Compared with the traditional air supply method that covers the entire front windshield at the same time, this alternating air supply method can make the airflow more concentrated, thereby further shortening the overall defrosting time, while improving the defrosting efficiency per unit airflow, and thus reducing the overall energy consumption of the air conditioning system during the defrosting process.

[0010] Optionally, adjusting the guide vanes so that the airflow is concentrated on the target frost area includes adjusting the guide vanes so that the airflow is concentrated on the target frost area when the target frost area is located only on one side of the left or right side of the windshield. Compared to a conventional air supply method that simultaneously covers the entire windshield, this air supply method can more concentrated the airflow, thereby further shortening the overall defrost time and improving the defrost efficiency per unit airflow, thereby reducing the overall energy consumption of the air conditioning system during the defrost process.

[0011] Optionally, detecting frost and fog areas on the target vehicle's windshield includes: detecting, in descending order of priority, whether each preset area on the windshield is a frost and fog area; the preset areas are obtained by dividing the windshield; and the priority corresponding to the preset area is positively correlated with the degree to which the presence of frost and fog in the preset area interferes with the driver's field of vision. Thus, prioritizing detection of high-priority preset areas can trigger a defrost response most quickly when frost and fog are present in critical areas, shortening the start-up time for frost and fog removal in high-risk areas; and if there is no frost and fog in the high-priority area, the system can terminate subsequent area detection early to save computing resources.

[0012] Optionally, detecting whether each preset area on the front windshield is a frost area in descending order of priority includes: selecting a target detection area from each preset area on the front windshield in descending order of priority; detecting the frost area within the target detection area; and determining whether the target detection area is a frost area by comparing the frost area with the area of the target detection area. This ensures that the frost status of high-priority areas is quickly determined, shortening the frost confirmation time in key visual field areas and prioritizing the initiation of defrosting operations in high-priority areas. Furthermore, by comparing the area, misjudgment caused by a small amount of local frost can be avoided, effectively eliminating interference from thin frost on the edge.

[0013] Optionally, comparing the frost fog area with the area of the target detection area to determine whether the target detection area is a frost fog area includes: calculating a frost-free fog area within the target detection area based on the frost fog area and the area of the target detection area; calculating a ratio of the frost-free fog area to the area of the target detection area to obtain a defrost rate for the target detection area; and determining whether the target preset area is a frost fog area based on whether the defrost rate exceeds a preset threshold. By calculating the defrost rate of the target preset area, the degree of frost fog obstruction is converted into a numerical basis for accurate determination, effectively avoiding misjudgments due to trace amounts of frost fog and avoiding redundant responses to localized frost fog that does not reach the threshold.

[0014] According to the second aspect of the present application, a vehicle window defrosting device is provided, comprising: a detection module for detecting a frost and fog area on the front windshield of a target vehicle; and an adjustment module for adjusting the guide vanes at a target air outlet on the front windshield of the target vehicle so that the airflow blown out from the target air outlet acts concentratedly on the frost and fog area.

[0015] According to a third aspect of the present application, an electronic device is provided, comprising: a processor; a memory for storing instructions executable by the processor; and the processor is configured to execute the method described in any one of the above embodiments.

[0016] According to a fourth aspect of the present application, a computer-readable storage medium is provided, wherein the storage medium stores a computer program, and the computer program is used to execute the method described in any one of the above embodiments.

[0017] The present application provides a vehicle window defrosting method, a vehicle, and a storage medium. The solution includes: after detecting the frost fog area on the front windshield of a target vehicle, adjusting the guide vanes at the target air outlet on the front windshield of the target vehicle so that the airflow blown out from the target air outlet is concentrated on the frost fog area. By concentrating the air conditioning energy on the frost fog area, the unit airflow defrosting efficiency is significantly improved, the frost fog in the key visual area can be quickly cleared, the defrosting time can be shortened, the line of sight can be avoided, and the driving safety risk can be reduced. At the same time, precise control of the airflow direction reduces energy waste and reduces the defrosting energy consumption of the air conditioning system, which helps to improve the cruising range of pure electric vehicles or the pure electric mode cruising range of hybrid vehicles.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0027] Application Overview

[0028] Frost on the windshield while driving will seriously affect the driver's vision, making it difficult for the driver to see road conditions, traffic signs and other vehicles, reducing driving safety. The driver can defrost the windshield by turning on the defrost function of the car's air conditioner.

[0029] In order to clear the frost, the air conditioner is operated in a high-power, high-air-volume mode. This mode usually requires the air conditioning system to operate at maximum output, consuming a large amount of electricity or engine power, resulting in high energy consumption. More importantly, the hot air generated by this defrosting method acts indiscriminately on the entire front windshield surface. However, in actual frost condensation scenarios, the frost often does not evenly cover the entire glass, but may be concentrated in specific areas. This strategy of supplying air to the entire glass surface over a large area lacks specificity, resulting in a large amount of effective airflow not directly acting on the frost area that actually needs to be cleared, but being wasted on dissipation or heating of frost-free areas. This inefficient energy utilization not only increases the load on the air conditioning system and prolongs the time required to achieve the ideal defrosting effect, but also significantly increases unnecessary energy consumption.

[0030] To address this issue, the present embodiment detects a frost-fog area on the front windshield of a target vehicle and then adjusts the guide vanes at the target air outlet on the target vehicle's front windshield, concentrating the airflow from the target air outlet on the frost-fog area. This creates a highly efficient heat exchange effect in the frost-fog area, significantly shortening the defrost cycle and alleviating blind spots caused by frost and fog, providing a reliable technical guarantee for driving safety.

[0031] After introducing the basic principles of the present application, various non-limiting embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0032] Exemplary Methods

[0033] Figure 1 It is a flow chart of a method for defrosting vehicle window glass provided by one embodiment of the present application. Figure 1 The method is executed by a computing device at the target vehicle, and this embodiment of the application does not limit this. Figure 1 As shown, the method includes the following contents:

[0034] Step S110: Detecting the frost area on the front windshield of the target vehicle.

[0035] In the embodiments of the present application, the vehicles may be any type of vehicle equipped with onboard air conditioning and air outlet adjustment functions, and there is no specific limitation on this.

[0036] In the embodiment of the present application, the front windshield may refer to a transparent glass component in front of the target vehicle's cab that is used to isolate the external environment and provide the driver with a forward field of view.

[0037] In the embodiment of the present application, the frost and fog area may refer to the distribution area of frost or fog that condenses on the inner surface of the windshield due to low temperature or humidity and blocks the line of sight.

[0038] In an embodiment of the present application, the detection of frost and fog areas on the front windshield of the target vehicle can be achieved by sensors arranged inside the vehicle, for example: the infrared sensor senses the surface temperature distribution data of the windshield, and identifies the area with a temperature below a set threshold as the frost and fog area; or, calculates the dew point temperature by detecting the ambient humidity, and identifies the area with a temperature below the dew point temperature as the frost and fog area; or, captures the image of the windshield through a camera, and the control unit analyzes the transmittance changes or texture features of the local area in the image, and identifies the area with a transmittance below the set threshold or a texture blur higher than the set threshold as the frost and fog area.

[0039] Step S220: adjusting the guide vanes at the target air outlet on the front windshield of the target vehicle so that the airflow blown out from the target air outlet acts on the frost and fog area.

[0040] In the embodiment of the present application, the target air outlet refers to an air conditioning outlet located near the front windshield of the target vehicle and configured to blow air toward the glass surface. The form of the target air outlet is not specifically limited and can be a single air outlet or a combination of multiple air outlets.

[0041] In the embodiments of the present application, the guide vanes may refer to blade assemblies installed at the target air outlet that adjust the direction and spread of the airflow by changing their angle. The angle of the guide vanes can be precisely controlled by a stepper motor or servo motor. The motor calculates the optimal rotation angle parameters based on the location coordinates, area size, and shape characteristics of the frost and fog area according to a preset control algorithm, and drives the vanes to rotate to the corresponding position to achieve directional focusing of the airflow.

[0042] When the target air outlet is configured as a single outlet, its shape can be configured as an elongated strip to achieve wide airflow coverage over the front windshield. The angle of each guide vane within the target air outlet can be controlled individually, or multiple vanes can be controlled in conjunction with a single motor. When the target air outlet is configured as multiple outlets, they can be distributed across the target vehicle's front windshield, with the angle of the guide vanes at each outlet being individually controllable.

[0043] In an embodiment of the present application, when it is detected that there are multiple scattered frost and fog areas on the front windshield, the angle of the guide blade can be controlled so that the airflow blown out from the target air outlet can accurately act on the corresponding frost and fog areas respectively; when there is only a single frost and fog area, the angle of the guide blade can be controlled so that the airflow can be more concentrated and efficiently swept through the area, thereby achieving targeted treatment of the frost and fog area.

[0044] In an embodiment of the present application, after detecting a frost-fog area on the front windshield of a target vehicle, the guide vanes at the target air outlet on the front windshield of the target vehicle are adjusted so that the airflow from the target air outlet is concentrated on the frost-fog area. This maximizes the delivery of limited air conditioning output energy to the local area that truly needs to clear the frost and fog, significantly improving the defrosting efficiency per unit airflow. This allows for rapid removal of frost and fog from critical visual areas, effectively shortening the defrosting time and preventing the driver's vision from being obstructed by frost and fog. This significantly reduces the driving safety risks associated with blurred vision.

[0045] At the same time, by precisely controlling the direction of airflow and reducing unnecessary energy consumption, the overall energy consumption of the air-conditioning system during the defrosting process can be significantly reduced, thereby helping to increase the cruising range of pure electric vehicles or the pure electric mode cruising range of hybrid vehicles.

[0046] based on Figure 1 The method in this specification also provides some specific implementation plans of the method, which are described below.

[0047] Optionally, adjusting the guide vanes at the target air outlet on the front windshield of the target vehicle so that the airflow blown out from the target air outlet acts concentratedly on the frost and fog area includes:

[0048] determining a target frost fog area with the highest priority from the frost fog areas; the priority corresponding to the frost fog area is positively correlated with the degree of interference of the frost fog in the frost fog area on the driver's field of vision;

[0049] The guide blades are adjusted so that the airflow acts on the target frost fog area in a concentrated manner.

[0050] In the embodiment of the present application, the target frost fog area may refer to the frost fog area that interferes most with the driver's field of vision; the target frost fog area is the primary action area of the current defrosting operation.

[0051] In an embodiment of the present application, the priority can be used to characterize the degree of interference of the frost and fog area on the driver's field of vision, and its value can be positively correlated with the position, area and degree of obstruction of the line of sight of the frost and fog area. For example, the frost and fog area located in the driver's central field of vision has a higher priority than the peripheral field of vision area; under similar positions, the larger the proportion of frost and fog area or the more severe the degree of obstruction, the higher the priority.

[0052] In an embodiment of the present application, the front windshield can be pre-divided into a plurality of preset areas. A priority is determined for each preset area based on the degree to which frost and fog interfere with the driver's field of vision. When the frost and fog area or proportion of a preset area exceeds a threshold, the preset area is determined as a frost and fog area.

[0053] Figure 2 FIG. 1 is a schematic diagram of a preset area on a front windshield provided by an embodiment of the present application; FIG. Figure 2 As shown, the front windshield is divided into eight preset areas: A1, B1, C1, D1, A2, B2, C2, and D2. Areas A1, B1, C1, and D1 are located on the driver's side, while areas A2, B2, C2, and D2 are located on the passenger side. The driver's side includes D1 at the top, A1 in the middle, the core field of view, C1 at the bottom, and B1 below A1 and above C1. Correspondingly, the passenger side includes D2 at the top, A2 in the middle, the core field of view, C2 at the bottom, and B2 below A2 and above C2. The priority of these preset areas can be set as follows: A1 = A2 > B1 = B2 > C1 = C2 > D1 = D2. Alternatively, A1 and A2 can be set as first priority, and B1, C1, D1, B2, C2, and D2 as second priority.

[0054] In another embodiment, the front windshield may not be pre-divided into preset areas, and the frost area on the front windshield of the target vehicle may be directly detected. The frost area may be continuous or discontinuous; the frost area that most interferes with the driver's field of view is determined as the target frost area.

[0055] In an embodiment of the present application, after detecting the frost and fog area on the front windshield of the target vehicle, the target frost and fog area that interferes most with the driver's field of vision is determined from the frost and fog area; and then the guide vanes are adjusted so that the airflow is concentrated on the target frost and fog area. In this way, the frost and fog areas that interfere most with the driver's field of vision and have the highest safety risks are cleared first, which significantly shortens the defrosting time of the key field of vision areas and further reduces the driving safety risks caused by obstructed vision. At the same time, during the entire defrosting process, the airflow is precisely directed to the target frost and fog areas that need to be cleared the most according to priority, that is, the airflow is concentrated only on the target frost and fog areas with the highest current priority. Since the airflow action range is more concentrated, the overall defrosting time is further shortened, and the defrosting efficiency per unit airflow is improved, thereby further reducing the overall energy consumption of the air-conditioning system during the defrosting process.

[0056] Optionally, adjusting the guide blades so that the airflow acts on the target frost fog area includes:

[0057] In the case that the target frost and fog areas exist on both the left and right sides of the front windshield, the angles of the guide blades are periodically adjusted so that the airflow acts alternately and concentratedly on each of the target frost and fog areas.

[0058] In the embodiment of the present application, making the airflow alternately concentrated on each of the target frost and fog areas may mean periodically switching the action area of the airflow at a preset time interval so that the airflow is focused on different target frost and fog areas in turn.

[0059] In this embodiment of the present application, after determining the highest-priority target frost area from the frost and fog areas, if there are multiple target frost and fog areas, and they are distributed on both the left and right sides of the front windshield, the angles of the guide vanes are adjusted so that the airflow is alternately concentrated on each of the target frost and fog areas. Compared to simultaneously dispersing air across multiple areas, the alternating concentrated blowing pattern delivers more focused energy to the target areas, shortening defrost time and improving defrost efficiency, while also reducing the overall energy consumption of the air conditioning system during the defrost process.

[0060] Optionally, the first area is an area on the driver's side of the center of the front windshield; the second area is an area on the passenger side of the front windshield;

[0061] When the target frost and fog areas exist on both the left and right sides of the front windshield, the angles of the guide blades are periodically adjusted so that the airflow acts alternately and concentratedly on each of the target frost and fog areas, including:

[0062] When both the first area and the second area belong to the target frost fog area, the following steps are taken in turn:

[0063] Cutting off the ventilation path on one side of the target air outlet close to the second area, opening the ventilation path on the other side, and adjusting the angle of the guide blades so that the airflow is concentrated on the first area;

[0064] The ventilation path on one side of the target air outlet close to the first area is cut off, the ventilation path on the other side is opened, and the angle of the guide blade is adjusted so that the airflow is concentrated on the second area.

[0065] In an embodiment of the present application, the first area is the area on the driver's side of the center part of the front windshield; the second area is the area on the passenger side of the center part of the front windshield; both the first area and the second area are areas with the strongest interference to the driver's field of vision, that is, areas with the highest priority.

[0066] In an embodiment of the present application, the ventilation path may refer to a channel structure inside the target air outlet for conveying the defrost airflow, which can be opened and closed by adjusting the guide blades or valves.

[0067] In an embodiment of the present application, the target air outlet can be a single long air outlet; cutting off the ventilation path on the side of the target air outlet close to the second area can be done by adjusting the angle of the guide blade to a closed state, or by setting two or more solenoid valves for control.

[0068] In an embodiment of the present application, when the target air outlet is provided as a plurality of air outlets, each air outlet is provided with a guide vane. Cutting off the ventilation path on the side of the target air outlet close to the second area can be done by adjusting the guide vane of the corresponding air outlet to close the air outlet, or by providing an independent solenoid valve for control.

[0069] Figure 3-Figure 4 These are all schematic diagrams of airflow distribution provided by the embodiments of this application. Figure 3 The image shows the passenger side guide vanes moving downward to close the target air outlet near the passenger side, while the driver side guide vanes moving upward to concentrate the defrost airflow on area A1 (i.e., the first area). Figure 4 The guide vanes on the driver's side are downward to close the target air outlet close to the driver's side, and the guide vanes on the passenger side are upward, so that the defrost airflow is concentrated on the A2 area (i.e. the second area).

[0070] When the two areas with the highest priority, A1 and A2, are both target frost and fog areas, they can be used alternately. Figure 3 and Figure 4 The two methods can be used for the same or different durations. If there is a difference, such as the driver's side takes longer, the cycle can be set to 30 seconds. Figure 3 The method shown acts for 20 seconds. Figure 4 The method shown works for 10 seconds; the time can also be divided according to the severity of the frost and fog in A1 and A2. In this way, when areas A1 and A2 are both target frost and fog areas, the frost and fog in A1 and A2 can be quickly cleared.

[0071] In this embodiment of the present application, the driver's side of the center of the front windshield is designated as the first zone, and the passenger side is designated as the second zone. When both the first and second zones are target frost and fog areas, the guide vanes are periodically adjusted to alternately focus the airflow on the first and second zones. Compared to blowing across the first and second zones simultaneously, this results in a more concentrated airflow on a single target frost and fog area, further shortening the overall defrost time and improving the defrost efficiency per unit airflow, thereby further reducing the overall energy consumption of the air conditioning system during the defrost process.

[0072] Optionally, when the target frost and fog areas exist on both the left and right sides of the front windshield, the angle of the guide vane is periodically adjusted so that the airflow acts alternately and concentratedly on each of the target frost and fog areas, including:

[0073] When there is no frost area at the center of the front windshield and the target frost area exists on both the left and right sides of the front windshield, all ventilation paths at the target air outlet are opened and the angle of the guide blades is periodically adjusted so that the airflow alternately covers the left and right parts of the front windshield.

[0074] In an embodiment of the present application, the ventilation path may refer to a channel structure inside the target air outlet for conveying the defrost airflow, which can be opened and closed by adjusting the guide blades or valves.

[0075] Figure 5-Figure 6 These are all schematic diagrams of airflow distribution provided in the embodiments of this application. Figure 5 The target air outlet is fully opened, the guide vanes are tilted toward the driver's side, and the defrost airflow covers the area of the front windshield near the driver's side; Figure 6 The central air outlet is also fully opened, with the guide blades biased toward the co-pilot side, and the defrost airflow covers the part of the front windshield close to the co-pilot side.

[0076] When the two areas A1 and A2 (i.e. the first and second areas) with the highest priority are not target frost fog areas, and there is at least one target frost fog area among B1, C1, and D1, and there is also at least one target frost fog area among B2, C2, and D2, you can alternately use Figure 5 and Figure 6 The two methods have similar action time, which can be the same or different. For example, with a cycle of 60 seconds, you can set Figure 5and Figure 6 The methods shown are each effective for 30 seconds, which allows for quick removal of frost and fog from the edges of the windshield.

[0077] In an embodiment of the present application, if there is no frost area at the center of the windshield and the target frost area exists on both the left and right sides of the windshield, all ventilation paths at the target air outlet are opened, and the angles of the guide vanes are periodically adjusted so that the airflow alternates between the left and right parts of the windshield. Compared to the traditional air supply method that simultaneously covers the entire windshield, this alternating air supply method can more concentrated the airflow, further shortening the overall defrost time and improving the defrost efficiency per unit airflow, thereby reducing the overall energy consumption of the air conditioning system during the defrost process.

[0078] Optionally, adjusting the guide blades so that the airflow acts on the target frost fog area includes:

[0079] In a case where the target frost fog area is located only on one side of the left side or the right side of the front windshield, the guide vanes are adjusted so that the airflow acts on the target frost fog area in a concentrated manner.

[0080] In an embodiment of the present application, when one of the first area and the second area belongs to the target frost fog area, the guide vanes are adjusted so that the airflow acts on the target frost fog area.

[0081] In an embodiment of the present application, when neither the first area nor the second area belongs to the target frost area, and the target frost area is located only on one side of the front windshield, the guide blades are adjusted so that the airflow acts concentratedly on the side of the front windshield where the target frost area exists.

[0082] Figure 3-Figure 6 are all airflow distribution diagrams provided in the embodiments of the present application; when the A1 area or A2 area with the highest priority is a frost fog area, Figure 3 and Figure 4 In the case that the target frost fog area only includes one or more of the B1, C1, and D1 areas, that is, in the case that only the left edge of the front window glass belongs to the frost fog area, you can use Figure 5 In the case where the target frost fog area only includes one or more of the B2, C2, and D2 areas, that is, when only the right edge of the front window glass belongs to the frost fog area, you can use Figure 6 The way to clear the frost fog.

[0083] In an embodiment of the present application, when the target frost area is located only on one side of the windshield, the guide vanes are adjusted to concentrate the airflow on the target frost area. Compared to conventional air supply methods that simultaneously cover the entire windshield, this air supply method can more concentrated the airflow, thereby further shortening the overall defrosting time and improving the defrosting efficiency per unit airflow, thereby reducing the overall energy consumption of the air conditioning system during the defrosting process.

[0084] Optionally, detecting a frost area on a front windshield of a target vehicle includes:

[0085] In descending order of priority, detect whether each preset area on the front windshield belongs to the frost and fog area; the preset areas are obtained by dividing the front windshield; the priority corresponding to the preset area is positively correlated with the degree of interference of the frost and fog in the preset area on the driver's field of vision.

[0086] In the embodiment of the present application, the predetermined area may refer to an independent sub-area formed by spatially dividing the front windshield, and the interference degree of each part in the same predetermined area to the driver's field of vision is roughly the same.

[0087] In the embodiment of the present application, the preset area can be divided according to the degree of interference to the driver's field of vision, for example, into a central field of vision area and a peripheral field of vision area. In order to improve the pertinence of the airflow, the central field of vision area and the peripheral field of vision area can be further divided, for example, the central field of vision area and the peripheral field of vision area can be divided into left and right parts, or the central field of vision area and / or the peripheral field of vision area can be divided into smaller areas. Specifically, Figure 2 As shown, the central visual area is evenly divided into two parts, A1 and A2; the peripheral visual area on the driver's side is further divided into three areas B1, C1, and D1, and the peripheral visual area on the co-pilot's side is further divided into three areas B2, C2, and D2.

[0088] In another embodiment, the preset area may also be a plurality of rectangular sub-areas divided into the front windshield according to horizontal and vertical grids, and then the priorities are set according to their locations.

[0089] In an embodiment of the present application, the priority is used to characterize the interference level of frost and fog in a preset area on the driver's vision. For example, the priority of the preset area located in the driver's central field of vision is higher than that of the peripheral field of vision, and the priority of the top area is lower than that of the central field of vision.

[0090] In an embodiment of the present application, each preset area on the front windshield is detected in descending order of priority to see whether it belongs to the frost and fog area; thus, the high-priority preset areas are detected first, which can trigger the defrost response as quickly as possible when frost and fog exist in the key areas, thereby shortening the frost and fog removal start-up time in the high-risk areas; at the same time, if there is no frost and fog in the high-priority areas, the system can terminate the subsequent area detection in advance to save computing resources.

[0091] Optionally, detecting whether each preset area on the front windshield belongs to the frost area in descending order of priority includes:

[0092] Select a target detection area from each preset area on the front windshield in descending order of priority:

[0093] Detecting the frost and fog area within the target detection area;

[0094] By comparing the frost and fog area with the area of the target detection area, it is determined whether the target detection area belongs to the frost and fog area.

[0095] In the embodiment of the present application, the target detection area refers to the current area to be detected selected from the preset areas in descending order of priority, that is, the preset area with a high priority is preferentially selected as the current target detection area.

[0096] In the embodiment of the present application, the frost and fog area may refer to the actual area of the portion covered by frost and fog within the target detection area.

[0097] In an embodiment of the present application, a specific method for detecting the frost and fog area can be: obtaining surface temperature distribution data of the target detection area through an infrared sensor, identifying frost and fog areas with temperatures lower than a set threshold, and then calculating the area of the frost and fog areas; calculating the dew point temperature based on ambient humidity data, identifying areas within the target detection area with surface temperatures lower than the dew point temperature as frost and fog areas, and then calculating the area of the frost and fog areas; collecting a local image of the target detection area through a camera, identifying areas in the image with a transmittance lower than a set threshold or a texture blur higher than a threshold as frost and fog areas, and then calculating the area of the frost and fog areas.

[0098] In this embodiment, target detection areas are selected from the pre-set areas in descending order of priority. Frost and fog areas are compared with the area of the target area to determine whether they are within the frost and fog area. This ensures that the frost and fog status of high-priority areas is quickly determined, shortening the time required to confirm frost and fog in key visual areas and prioritizing defrosting operations in high-priority areas. Furthermore, area comparison avoids misjudgments caused by small amounts of localized frost and fog, effectively eliminating interference from thin frost on the edges.

[0099] Optionally, the determining whether the target detection area belongs to the frost and fog area by comparing the frost and fog area with the area of the target detection area includes:

[0100] Calculating a frost-free area within the target detection area based on the frost-fog area and the area of the target detection area;

[0101] Calculating a ratio of the frost-free fog area to the area of the target detection area to obtain a defrost rate of the target detection area;

[0102] According to whether the defrost rate exceeds a preset threshold, it is determined whether the target preset area belongs to a frost and fog area.

[0103] In the embodiment of the present application, the frost-free fog area refers to the area within the target detection area that is not covered by frost or fog, which is calculated by subtracting the frost-free fog area from the total area of the target detection area.

[0104] In the embodiment of the present application, the defrost rate is the ratio of the frost-free fog area to the area of the target detection area, which can represent the current frost-free fog state of the area in the form of a percentage.

[0105] In an embodiment of the present application, the preset threshold may refer to a critical value used to determine whether a specific area belongs to a frost and fog area; the preset threshold may be set differently according to the priority of the preset area, and the preset threshold of the high priority area is higher than that of the low priority area. For example, the preset threshold of the high priority area (such as the central visual field) is 65%, and the preset threshold of the low priority area (such as the bottom of the windshield) is 50%. The defrost rate is compared with the corresponding threshold to determine whether it belongs to the frost and fog area.

[0106] In this embodiment of the present application, the frost-free area within the target detection area is calculated based on the frost-free area and the area of the target detection area. The defrost rate of the target detection area is calculated by calculating the ratio of the frost-free area to the area of the target detection area. Whether the preset area is a frost-free area is determined based on whether the defrost rate exceeds a preset threshold. By calculating the defrost rate of the target preset area, the degree of frost obstruction is converted into a numerical value that can be accurately determined, effectively avoiding misjudgments caused by trace amounts of frost and fog, and avoiding redundant responses to localized frost and fog that does not reach the threshold.
