Description

Technical Field

[0001] This application relates to the field of vehicle control, and more specifically, to a vehicle control method, apparatus, vehicle, and computer-readable storage medium in the field of vehicle control. Background Technology

[0002] Currently, the vehicle's defrosting and defogging functions are pre-defined and cannot be changed. After the user turns on the defrosting and defogging functions, the air conditioning fan speed and temperature are set to maximum, and the airflow direction is fixed. This causes the fog or frost on the area of ​​the windshield directly opposite the air conditioning vents to be removed first, followed by fog or frost in other areas. This process is a removal process from the middle to the sides, which cannot quickly make the area of ​​the windshield in the driver's line of sight clear, making it difficult for the driver to clearly see the environmental conditions in front of the vehicle in a short period of time. Summary of the Invention

[0003] This application provides a vehicle control method, device, vehicle, and computer-readable storage medium. This application realizes dynamic defrosting or defogging of the vehicle's windshield based on the driver's height. Specifically, it dynamically divides the windshield into zones based on the driver's line-of-sight height differences, dynamically prioritizing the removal of frost or fog from areas of high driver attention, followed by areas of low driver attention. This ensures that the driver can clearly see the environmental conditions in front of the vehicle in a short time, which is beneficial to improving driving safety and comfort. The vehicle's defrosting or defogging method is applicable to drivers of different heights, better meeting the actual driving needs of drivers.

[0004] Firstly, a vehicle control method is provided, comprising: when it is determined that the attachments on the windshield meet the removal conditions, dividing the windshield into regions according to the driver's field of vision to obtain multiple target regions; sorting the multiple target regions according to the driver's attention to each of the multiple target regions to obtain a sorting result; wherein the multiple target regions in the sorting result are sorted from high to low according to the attention level; and sequentially reducing the degree of obstruction of the driver's line of vision by the attachments on each target region in the sorting result.

[0005] In the above technical solution, this application embodiment adopts a method that, when determining that the attachments on the windshield meet the removal conditions, divides the windshield into multiple target areas based on the driver's field of vision. These target areas are then sorted according to the driver's level of attention to each area, resulting in a sorting result. The sorted target areas are ranked from highest to lowest level of attention, thereby reducing the degree to which the attachments on each target area obstruct the driver's view. This method achieves dynamic area division of the windshield based on the driver's height, dynamically prioritizing the removal of frost or fog from areas of high driver attention, followed by areas of low driver attention. This ensures that the driver can clearly see the environment in front of the vehicle in a short time, improving driving safety and comfort. It also makes the vehicle's defrosting or defogging method suitable for drivers of different heights, better meeting the actual driving needs of drivers.

[0006] In conjunction with the first aspect, in some possible implementations, the plurality of target regions include the first to fifth regions;

[0007] The step of dividing the windshield into multiple target areas based on the line of sight includes: defining the intersection of the line of sight and the windshield as a first area; one side of the first area is opposite to the area where the driver's seat is located, and the other side of the first area is opposite to the area where the passenger seat is located; based on the first area, using the dividing line between the areas where the driver's seat is located and the areas where the passenger seat is located as the dividing line, dividing the area on the windshield other than the first area into four areas; defining the area in the four areas that is opposite to the area where the driver's seat is located and located above the first area as a second area; defining the area in the four areas that is opposite to the area where the driver's seat is located and located below the first area as a third area; defining the area in the four areas that is opposite to the area where the passenger seat is located and located above the first area as a fourth area; and defining the area in the four areas that is opposite to the area where the passenger seat is located and located below the first area as a fifth area.

[0008] In combination with the first aspect and the above implementation methods, in some possible implementation methods, the step of sorting the multiple target areas according to the driver's attention to each of the multiple target areas to obtain the sorting result includes: the driver's attention to each of the first to fifth areas decreases in sequence, and the sorting result is the first area, the second area, the third area, the fourth area, and the fifth area.

[0009] In combination with the first aspect and the above implementation methods, in some possible implementation methods, the step of sequentially reducing the degree of obstruction of the driving line of sight by the attachments on each target region in the sorting result includes: sequentially reducing the degree of obstruction of the driving line of sight by the attachments on the first to fifth regions to the first threshold corresponding to each of the first to fifth regions; wherein, the first threshold corresponding to each of the first to fifth regions increases sequentially.

[0010] In conjunction with the first aspect and the above implementation, in some possible implementations, after the obstruction of the driver's line of sight by the attachments on the first to fifth regions is sequentially reduced to the first threshold corresponding to each of the first to fifth regions, the vehicle control method further includes: sequentially reducing the obstruction of the driver's line of sight by the attachments on at least one of two adjacent regions in the first to fifth regions, so that the difference in the obstruction of the driver's line of sight by the attachments on the two adjacent regions is not less than a second threshold; wherein, the first threshold is greater than the second threshold.

[0011] In conjunction with the first aspect and the above implementation, in some possible implementations, after the degree of obstruction of the driver's line of sight by the attachments on at least one of two adjacent regions in the first to fifth regions is successively reduced, the vehicle control method further includes: successively reducing the degree of obstruction of the driver's line of sight by the attachments on the first to fifth regions to a third threshold, wherein the third threshold is less than the second threshold.

[0012] The aforementioned technical solution removes debris from the windshield in three stages. The first stage optimizes the driver's field of vision, ensuring the driver can clearly see the environment ahead of the vehicle in a short time, thus facilitating safe driving and preventing accidents. The second stage optimizes the field of vision even further, and the third stage achieves the same level of clarity. This dynamic approach, combining the driver's field of vision with the removal of debris from the windshield, makes the method suitable for drivers of different heights and better meets their actual driving needs.

[0013] In conjunction with the first aspect and the above implementation, in some possible implementations, after the obstruction of the driver's line of sight by the attachments on the first to fifth regions to the third threshold is sequentially reduced, the vehicle control method further includes: when it is determined again that the removal condition of the attachments on the windshield is met, determining whether the driver's line of sight has shifted relative to the height direction of the windshield; if not, performing the step of sequentially reducing the obstruction of the driver's line of sight by the attachments on each target region in the sorting result; if so, performing the step of dividing the windshield into regions according to the driver's line of sight to obtain multiple target regions.

[0014] Secondly, a vehicle control device is provided, the vehicle control device comprising:

[0015] The area division module is used to divide the windshield into multiple target areas based on the driver's field of vision when it is determined that the attachments on the windshield meet the removal conditions.

[0016] The region sorting module is used to sort the multiple target regions according to the driver's attention to each of the multiple target regions, and obtain a sorting result; wherein, in the sorting result, the multiple target regions are sorted from high to low according to the attention level;

[0017] The target removal module is used to sequentially reduce the degree to which the attachments on each target area in the sorting results obstruct the driver's line of sight.

[0018] In conjunction with the second aspect, in some possible implementations, the plurality of target areas includes first to fifth areas. Specifically, the area division module is used to determine the intersection area of ​​the line of sight and the windshield as the first area. One side of the first area is opposite to the area where the driver's seat is located, and the other side of the first area is opposite to the area where the passenger seat is located. Based on the first area, using the boundary line between the areas where the driver's seat and the passenger seat are located as the dividing line, the area on the windshield other than the first area is divided into four areas. The area among the four areas that is opposite to the area where the driver's seat is located and located above the first area is determined as the second area. The area among the four areas that is opposite to the area where the driver's seat is located and located below the first area is determined as the third area. The area among the four areas that is opposite to the area where the passenger seat is located and located above the first area is determined as the fourth area. The area among the four areas that is opposite to the area where the passenger seat is located and located below the first area is determined as the fifth area.

[0019] In combination with the second aspect and the above implementation methods, in some possible implementation methods, the region sorting module is specifically used to make the driver's attention to each of the first to fifth regions decrease sequentially, and the sorting result is the first region, the second region, the third region, the fourth region, and the fifth region.

[0020] In combination with the second aspect and the above implementation methods, in some possible implementations, the target removal module includes:

[0021] A first control unit is configured to sequentially reduce the degree to which the attachments on the first to fifth regions obstruct the driver's line of sight to a first threshold corresponding to each of the first to fifth regions; wherein the first threshold corresponding to each of the first to fifth regions increases sequentially.

[0022] In combination with the second aspect and the above implementation methods, in some possible implementations, the target removal module includes:

[0023] The second control unit is configured to sequentially reduce the degree of obstruction of the driver's line of sight by the attachments on at least one of two adjacent areas in the first to fifth regions, such that the difference in the degree of obstruction of the driver's line of sight by the attachments on the two adjacent areas is not less than a second threshold; wherein the first threshold is greater than the second threshold.

[0024] In combination with the second aspect and the above implementation methods, in some possible implementations, the target removal module includes:

[0025] A third control unit is configured to sequentially reduce the degree to which the attachments on the first to fifth regions obstruct the driver's line of sight to a third threshold, the third threshold being less than the second threshold.

[0026] In conjunction with the second aspect and the above-described implementations, in some possible implementations, the vehicle control device further includes:

[0027] The judgment unit is used to determine whether the driver's field of vision has shifted relative to the height of the windshield when the removal conditions for the attachments on the windshield are met again; if not, the step of sequentially reducing the degree of obstruction of the driver's field of vision by the attachments on each target area in the sorting results is executed; if yes, the step of dividing the windshield into areas according to the driver's field of vision to obtain multiple target areas is executed.

[0028] Thirdly, a vehicle is provided, including a memory and a processor.

[0036] Figure 6 A schematic diagram of the structure of a vehicle provided in an embodiment of this application is shown. Detailed Implementation

[0037] The technical solutions in this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.

[0038] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0039] Currently, the vehicle's defrosting and defogging functions are pre-defined and cannot be changed. When the user activates these functions, the air conditioning fan speed and temperature are set to maximum, and the airflow direction is fixed. This causes the fog or frost on the area of ​​the windshield directly opposite the air conditioning vents to be removed first, followed by other areas. This process, where the fog or frost is removed from the center first and then the sides, fails to quickly clear the area of ​​the windshield directly in the driver's line of sight, making it difficult for the driver to clearly see the environment ahead of the vehicle in a short time. Furthermore, this fixed defrosting and defogging method is unsuitable for drivers of different heights. Taller drivers have a higher line of sight, making it difficult for them to see the environment ahead through the upper part of the windshield quickly. Similarly, shorter drivers have a lower line of sight, making it difficult for them to see the environment ahead through the lower part of the windshield quickly.

[0040] Addressing the problems of existing defogging and defrosting methods, this application provides a vehicle control method, device, vehicle, and computer-readable storage medium. This application divides the vehicle's windshield into multiple areas based on the driver's line of sight. Each area corresponds to the driver's level of attention to that area, indicating the priority for defrosting or defogging that area. Areas with higher attention are prioritized for defrosting or defogging. When defrosting or defogging is needed, priority is given to areas with higher attention to ensure the driver's view is unobstructed. Areas with lower attention are then defogging or defrosting, thus completing the defrosting or defogging of the entire windshield. This achieves dynamic area division of the windshield based on differences in the driver's line of sight height, dynamically prioritizing the removal of frost or fog from areas with higher driver attention, followed by areas with lower attention. This ensures the driver can clearly see the environment ahead of the vehicle in a short time, improving driving safety and comfort. The vehicle's defrosting or defogging method is applicable to drivers of different heights, better meeting the actual driving needs of drivers.

[0041] The following is an embodiment of a vehicle control method provided in this application.

[0042] Figure 1A schematic flowchart of a vehicle control method provided in an embodiment of this application is shown, such as... Figure 1 As shown, the vehicle control method provided in this application embodiment is applied to a vehicle, and the vehicle control method includes the following schemes:

[0043] S110: When it is determined that the attachments on the windshield meet the removal conditions, the windshield is divided into areas according to the driver's field of vision to obtain multiple target areas.

[0044] In an exemplary embodiment, "attachment" can be understood as frost, dust, or other substances that can be automatically removed by the vehicle and that can interfere with the driver's vision. For example, the presence of attachment on the windshield can be understood as frost condensing on the windshield. The removal conditions for attachment on the windshield can be understood as defrosting conditions. Determining whether the removal conditions are met includes the vehicle automatically detecting attachment on the windshield and the attachment interfering with the driver's vision, preventing the driver from clearly observing the environmental conditions in front of the vehicle, and / or the driver actively triggering the attachment removal function, such as turning on the physical switch of the attachment removal function or issuing a voice command to activate the attachment removal function.

[0045] Once the removal conditions (such as defrosting conditions) are met, the in-vehicle camera captures a gaze image of the driver looking at the front of the vehicle. The gaze image includes the driver's eyes, the windshield, and the external environment. The driver's field of vision is identified through the gaze image, and then the driver's line of sight relative to the windshield is identified from the driver's field of vision.

[0046] A driver's field of vision refers to the visible area in front of and around the vehicle that the driver can directly observe while driving. The driver's field of vision is crucial for ensuring driving safety because it directly affects the driver's ability to promptly detect potential hazards and react appropriately. Specifically, the driver's line of sight refers to the direction of their gaze, directly related to the direction and focus of their vision; the driver's field of view refers to the entire spatial range that can be captured by the driver's eyes at any given moment, including the focal area of ​​their gaze and the surrounding visual range. For example... Figure 2 As shown, Figure 2 A schematic diagram of the driver's gaze image is shown. Figure 2 In this context, θ represents the driver's field of vision, and θ1 represents the driver's line of sight.

[0047] Drivers of different heights have different fields of vision relative to the windshield. For example... Figure 3 As shown, Figure 3 This diagram illustrates the field of vision relative to the windshield for drivers of different heights, where F represents the windshield. Figure 3The area S0 formed between the two solid horizontal lines is the horizontal middle area of ​​the windshield. Figure 3 In the left-hand diagram, the area S1 formed between the two dashed horizontal lines represents the driver B's field of vision. Figure 3 In the diagram on the right, the area S2 formed between the two dashed horizontal lines represents the line of sight of driver A. Driver A is shorter than driver B. Figure 3 As can be seen, region S1 is higher than region S0, region S2 is lower than region S0, and region S1 is higher than region S2. This means that driver B's field of vision is different from driver A's field of vision. Driver B's field of vision on the windshield is higher than driver A's field of vision.

[0048] After obtaining the driver's field of vision, the windshield of the vehicle is divided into areas based on the driver's field of vision, resulting in multiple target areas. These target areas include the target area corresponding to the driver's field of vision, the target area directly in front of the area where the driver's seat is located, and the area where the passenger seat is located.

[0049] The positions of the target areas on the windshield will differ depending on the driver's height. For example, if driver A is shorter than driver B, then driver A's field of vision will be different from driver B's, and the target areas defined by driver A's field of vision will appear differently on the windshield than those defined by driver B's field of vision.

[0050] S120: Based on the driver's level of attention to each target area, sort the multiple target areas to obtain a sorting result; wherein, in the sorting result, the multiple target areas are sorted from high to low according to the level of attention.

[0051] After obtaining multiple target areas, the driver's attention level is set for each target area. Since the windshield is located in front of the areas where the driver's seat and the passenger seat are located, removing the attachments on the windshield is to allow the driver to clearly see the environmental conditions in front of the vehicle. That is, the target area corresponding to the driver's line of sight has the highest attention level among the multiple target areas, the target area directly in front of the area where the driver's seat is located has the second highest attention level, and the target area directly in front of the area where the passenger seat is located has the lowest attention level.

[0052] Attention level indicates the priority of removing obstructions from a target area, and attention level is positively correlated with priority. Target areas with higher attention levels are ranked higher, meaning the obstructions on the target area should be removed earlier; target areas with lower attention levels are ranked lower, meaning the obstructions on the target area should be removed later. Target areas requiring early obstruction removal indicate that the obstructions in the target area severely interfere with the driver's vision, while target areas requiring later obstruction removal indicate that the obstructions in the target area less interfere with the driver's vision.

[0053] S130: Sequentially reduce the degree to which the attachments on each target area in the sorting results obstruct the driver's line of sight.

[0054] The degree of obstruction is inversely related to the clarity of the driver's view of the environment ahead through the windshield (also known as the clarity of the driver's line of sight). A higher degree of obstruction results in lower clarity of the driver's line of sight, meaning a more blurred view, poorer visibility of the environment ahead, and more dangerous driving. Conversely, a lower degree of obstruction results in higher clarity of the driver's line of sight, meaning a clearer view, better visibility of the environment ahead, and safer driving. Specifically, when the deposit is frost, the degree of obstruction is determined by the degree of frost formation, and the degree of frost formation is inversely related to the clarity of the driver's line of sight. When the deposit is fog, the degree of obstruction is determined by the degree of fog formation, and the degree of fog formation is inversely related to the clarity of the driver's line of sight.

[0055] After obtaining the sorting results of multiple target areas, the degree to which the deposits on each target area obstruct the driver's view is reduced sequentially, ensuring unobstructed visibility and allowing the driver to observe the environment ahead of the vehicle normally through the windshield for safe driving. Specifically, the amount of deposits adhering to the windshield is reduced to decrease the degree of obstruction. If the deposits are frost or fog, the air conditioning vents can be controlled to blow warm air at a higher speed; if the deposits are dust, the air conditioning vents can be controlled to blow air at a higher speed.

[0056] The process of reducing the obstruction of the driver's line of sight by the attachments on each target area in the ranking results can be understood as first reducing the obstruction of the driver's line of sight by the attachments on the target area with the highest level of attention in the ranking results. After reducing the obstruction of the driver's line of sight by the attachments on the target area with the highest level of attention and ensuring that the driver's line of sight is not obstructed, the process of reducing the obstruction of the driver's line of sight by the attachments on the target area with the second highest level of attention continues, and so on, until the obstruction of the driver's line of sight by the attachments on the target area with the lowest level of attention is completed.

[0057] For example, if the deposit is frost, and there are multiple target areas including areas 1 to 3, and the sorting result is area 3, area 2 and area 1, then first remove the frost on area 3. After the degree of frost on area 3 is reduced and the driver's driving vision is not obstructed, continue to remove the frost on area 2. After the degree of frost on area 2 is reduced, continue to remove the frost on area 1. After the degree of frost on area 1 is reduced, the windshield is defrosted in this way.

[0058] This application embodiment employs a technical solution that, when determining that the deposits on the windshield meet the removal conditions, divides the windshield into multiple target areas based on the driver's field of vision. These target areas are then ranked according to the driver's level of attention to each area, resulting in a ranking result. The ranking of the target areas from highest to lowest level of attention reduces the degree to which the deposits on each target area obstruct the driver's view. This achieves dynamic area division of the windshield based on the driver's height, dynamically prioritizing the removal of frost or fog from areas of high driver attention, followed by areas of low driver attention. This ensures that the driver can clearly see the environment ahead of the vehicle in a short time, improving driving safety and comfort. Furthermore, it makes the vehicle's defrosting or defogging method suitable for drivers of different heights, better meeting the actual driving needs of drivers.

[0059] The following are Figure 1 The specific implementation methods of each step in the illustrated embodiment will be explained below:

[0060] In one possible implementation, the number of zones for dividing the windshield is predetermined, for example, five zones, meaning multiple target zones include zones one through five. The above-mentioned S110, which divides the windshield into zones based on the field of vision, yields multiple target zones including the following schemes:

[0061] like Figure 4 As shown, Figure 4 This diagram illustrates the division of the windshield into zones. After determining the driver's field of vision, the intersection area between the driver's field of vision and the windshield is determined; this intersection area is... Figure 4 The area formed by the two horizontal dotted lines is defined as the first area, denoted as area A, which is the intersection of the driver's line of sight and the windshield. One side of the first area is opposite to the area where the driver's seat is located, and the other side of the first area is opposite to the area where the passenger seat is located.

[0062] After identifying the first region on the windshield, based on the first region and using the dividing line between the areas where the driver's seat and the passenger seat are located as the dividing line, the area on the windshield excluding the first region is divided into four regions: region B, region C, region D, and region E. The region in these four regions that is opposite to the area where the driver's seat is located and above the first region is designated as the second region, i.e., region B; the region in these four regions that is opposite to the area where the driver's seat is located and below the first region is designated as the third region, i.e., region C; the region in these four regions that is opposite to the area where the passenger seat is located and above the first region is designated as the fourth region, i.e., region D; and the region in these four regions that is opposite to the area where the passenger seat is located and below the first region is designated as the fifth region, i.e., region E.

[0063] In one possible implementation, the above-mentioned S120 sorts the multiple target areas according to the driver's level of attention to each of the multiple target areas, and the sorting result includes the following schemes:

[0064] Because the first area is the intersection of the driver's field of vision and the windshield, the driver primarily observes the environment ahead of the vehicle through this area, thus paying the highest attention to it. The second and third areas are directly in front of the driver, while the fourth and fifth areas are to the driver's right (in front of the passenger seat area). Therefore, the driver pays more attention to the second and third areas than to the fourth and fifth. The second area is above the first and is not obstructed by the vehicle body, allowing the driver to see further. The third area is below the first, and because it is close to the hood, the hood obstructs the driver's view through it. Therefore, the second area receives more attention than the third. Similarly, regarding the driver's attention to the fourth and fifth areas, the fourth area is located above the first area and is not obstructed by the vehicle body. The driver or front passenger can see a greater distance through the fourth area. The fifth area is located below the first area and is close to the vehicle's hood. The driver or front passenger can see the hood through the fifth area, meaning the hood will obstruct the driver's view of the outside environment through the fifth area. Therefore, the driver or front passenger's attention to the fourth area is higher than that to the fifth area. Thus, we can obtain the attention level corresponding to the first area > the attention level corresponding to the second area > the attention level corresponding to the third area > the attention level corresponding to the fourth area > the attention level corresponding to the fifth area. That is, the driver's attention level to each of the first to fifth areas decreases in that order. Therefore, the ranking result is the first area, the second area, the third area, the fourth area, and the fifth area. In other words, the priority order for removing attachments is: the priority of the first area > the priority of the second area > the priority of the third area > the priority of the fourth area > the priority of the fifth area.

[0065] In one possible implementation, the above-mentioned S130, which sequentially reduces the degree of obstruction of the driver's line of sight by the attachments on each target area in the sorting result, includes the following schemes:

[0066] The degree to which the attachments on the first to fifth regions obstruct the driver's line of sight is reduced sequentially to the first threshold corresponding to each of the first to fifth regions.

[0067] First thresholds are pre-set for each of the first to fifth regions, and the first thresholds for each of the first to fifth regions increase sequentially. For example, the first thresholds for each of the first to fifth regions are a, b, c, d and e, respectively, where a < b < c < d < e.

[0068] After obtaining the sorting results, it is determined whether the obstruction of the driver's view by the attachments in at least one of the first to fifth regions exceeds the first threshold corresponding to that region. If so, the obstruction of the driver's view by the attachments in the first region is first reduced to the first threshold corresponding to the first region. Next, the obstruction of the driver's view by the attachments in the second region is reduced to the first threshold corresponding to the second region, and so on. Finally, the obstruction of the driver's view by the attachments in the fifth region is reduced to the first threshold corresponding to the fifth region. However, after successively reducing the obstruction of the driver's view by the attachments in the first to fifth regions to their respective first thresholds, the attachments in each region are not completely removed. The external environment can still be clearly seen through each region. The driver's clarity of the external environment through the first region is higher than that through the second region, the driver's clarity of the external environment through the second region is higher than that through the third region, the driver's clarity of the external environment through the third region is higher than that through the fourth region, and the driver's clarity of the external environment through the fourth region is higher than that through the fifth region. Prioritizing the reduction of the obstruction of the driver's line of sight by attachments in the first area to the first threshold corresponding to the first area ensures that the obstruction of the driver's line of sight by attachments in the most important area is reduced first, so that the driver can see the environmental conditions in front of the vehicle through the first area at the first time, which helps to improve driving safety.

[0069] The above technical solution achieves the first removal of deposits on the windshield, that is, while ensuring that the driver can drive the vehicle normally, it reduces the amount of deposits on the windshield, such as reducing the thickness of frost on the windshield, thereby ensuring that the driver can see the external environment through the entire windshield.

[0070] In one possible implementation, after the degree of obstruction of the driver's line of sight by the attachments in the first to fifth regions is reduced to the first threshold corresponding to each of the first to fifth regions, the vehicle control method further includes the following scheme:

[0071] Since there are still some attachments on the windshield after the first removal of the attachments, and the attachments are not completely removed, a second removal is performed on the windshield. This involves successively reducing the degree of obstruction of the driver's view by the attachments in at least one of the two adjacent areas in the first to fifth regions, so that the difference in the degree of obstruction of the driver's view by the attachments in the two adjacent areas is not less than a second threshold, and the first threshold is greater than the second threshold.

[0072] For example, a=20, b=25, c=30, d=35, and e=40, with the second threshold being greater than or equal to 6. After reducing the obstruction of the driver's view by the attachments in the first area to 20, the obstruction by the attachments in the second area to 25, the obstruction by the attachments in the third area to 30, the obstruction by the attachments in the fourth area to 35, and the obstruction by the attachments in the fifth area to 40, for cases where the first and second areas are adjacent, for example, reducing the obstruction by the attachments in the first area to 12 and reducing the obstruction by the attachments in the second area to 20; for cases where the second and third areas are adjacent, for example, reducing the obstruction by the attachments in the second area to 15 and reducing the obstruction by the attachments in the third area to 22, and so on, a second removal of the attachments on the windshield is achieved. After the second removal of the debris from the windshield, some debris remained on the windshield. After the second removal, the driver could see the outside environment through the windshield more clearly than after the first removal, thus further improving the driver's visibility.

[0073] In one possible implementation, after successively reducing the degree of obstruction of the driver's line of sight by attachments on at least one of two adjacent areas in the first to fifth regions, the vehicle control method further includes the following:

[0074] Since there are still some attachments on the windshield after the second removal of the attachments, and the attachments are not completely removed, a third removal is performed on the windshield. This means that the degree of obstruction of the driver's vision by the attachments in the first to fifth areas is reduced to a third threshold, which is less than the second threshold. The third threshold is generally set to 0.

[0075] The third removal of debris from areas one through five follows the same sequence as the first removal. First, the obstruction of the driver's view by the debris in area one is reduced to the third threshold, meaning the debris in area one is completely removed. Then, the obstruction of the driver's view by the debris in area two is reduced to the third threshold, meaning the debris in area two is completely removed, and so on, until all debris on the windshield is completely removed. After the third removal of debris, the driver can see the outside environment through the windshield more clearly than after the second removal of debris, thus further optimizing the driver's view.

[0076] The aforementioned technical solution removes debris from the windshield in three stages. The first stage optimizes the driver's field of vision, ensuring the driver can clearly see the environment ahead of the vehicle in a short time, thus facilitating safe driving and preventing accidents. The second stage optimizes the field of vision even further, and the third stage achieves the same level of clarity. This dynamic approach, combining the driver's field of vision with the removal of debris from the windshield, makes the method suitable for drivers of different heights and better meets their actual driving needs.

[0077] In one possible implementation, after successively reducing the degree of obstruction of the driver's line of sight by the attachments on each target area in the sorting results, when it is determined again that the removal conditions of the attachments on the windshield are met, it is determined whether the driver's line of sight has shifted relative to the height of the windshield.

[0078] If not, proceed with the steps of successively reducing the degree to which the attachments on each target area in the sorting results obstruct the driver's view;

[0079] If so, proceed with the step of dividing the windshield into zones based on the driver's line of sight to obtain multiple target zones.

[0080] Considering that the driver of the same vehicle may change or the driver's posture may change or not, the driver's field of vision generally does not change when the driver does not change or the posture does not change. Therefore, it is not necessary to divide the windshield into sections every time it is necessary to remove the attachments on the windshield. Therefore, after initially dividing the windshield into zones based on the driver's field of vision, and sequentially reducing the degree of obstruction to the driver's view by the attachments on each target zone in the sorting results, so that the attachments on the windshield are completely removed, if the removal conditions for the attachments on the windshield are met again, it is determined whether the driver's field of vision has shifted relative to the height of the windshield. If not, it means that the driver has not changed and the seating posture has not changed, and S130 is executed directly, thereby quickly removing the attachments and improving driving safety. If yes, it means that the driver has changed or the seating posture has changed, and S110-S130 are executed. This achieves dynamic removal of the attachments on the windshield based on the driver's field of vision, making the attachment removal method applicable to drivers of different heights and more in line with the actual driving needs of drivers.

[0081] The above embodiments will be described below using frost as an example of the deposited substance.

[0082] The above vehicle control methods can be understood as vehicle defrosting methods, and the vehicle control methods include the following schemes:

[0083] Step 201: When it is determined that the defrosting conditions of the windshield are met, the windshield is divided into regions according to the driver's line of sight, resulting in multiple target regions. The multiple target regions include regions one through five. Region one is the first region, and one side of region one is opposite to the region where the driver's seat is located, and the other side of region one is opposite to the region where the passenger seat is located. Region two is opposite to the region where the driver's seat is located and is located above region one. Region three is opposite to the region where the driver's seat is located and is located below region one. Region four is opposite to the region where the passenger seat is located and is located above region one. Region five is opposite to the region where the passenger seat is located and is located below region one.

[0084] Step 202: Based on the driver's level of attention to each of the multiple target areas, sort the multiple target areas to obtain a sorting result. In the sorting result, the multiple target areas are sorted from high to low according to the level of attention, that is, the sorting result is the first area, the second area, the third area, the fourth area, and the fifth area.

[0085] Step 203: Determine whether the first condition for the first defrosting is met; if it is met, proceed to step 204; if it is not met, proceed to step 205; the first condition is that the degree of frost in at least one of the first, second, third, fourth and fifth regions is greater than the first threshold corresponding to that region.

[0086] Step 204: Sequentially reduce the frosting level of the first to fifth regions to the first threshold corresponding to each of the first to fifth regions, and sequentially increase the first threshold corresponding to each of the first to fifth regions.

[0087] Step 205: Determine whether the second condition for the second defrosting is met; if it is met, proceed to step 206; if it is not met, proceed to step 207; the second condition is that the difference in the degree of frost between two adjacent areas in the first to fifth regions is less than the second threshold.

[0088] Step 206: Sequentially reduce the frosting level of at least one of two adjacent regions in the first to fifth regions, so that the difference in frosting level between two adjacent regions is not less than the second threshold.

[0089] Step 207: Determine whether the third condition for the third defrosting is met; if it is met, proceed to step 208; if it is not met, proceed to step 209; the third condition is that the degree of frost in at least one of the first, second, third, fourth, and fifth regions is greater than the third threshold corresponding to that region, and the third threshold is less than the second threshold.

[0090] Step 208: Sequentially reduce the frosting level of the first to fifth regions to the third threshold.

[0091] Step 209: Exit defrosting.

[0092] Based on the completion of steps 201 to 202, further steps 203, 204, 205, 206, 207, and 208 are performed for cases of severe frost buildup (thick frost) on the windshield, involving three defrosting steps. Based on the completion of steps 201 to 202, further steps 203, 205, 206, 207, and 208 are performed for cases of moderate frost buildup on the windshield, involving two defrosting steps. Based on the completion of steps 201 to 202, further steps 203, 205, 207, and 208 are performed for cases of thin frost buildup on the windshield, involving a single defrosting step.

[0093] Based on the above technical solution, the windshield is dynamically divided into zones according to the driver's line of sight height. The frost is dynamically removed first from the areas that the driver pays more attention to, and then from the areas that the driver pays less attention to. This ensures that the driver can clearly see the environment in front of the vehicle in a short time, which is conducive to improving driving safety and comfort. The vehicle defrosting method is suitable for drivers of different heights and is more in line with the actual driving needs of drivers.
