[0016] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0018] In the related art, in modern traffic environments, driving safety is extremely dependent on the driver's visual clarity, especially through the front windshield of the car. However, the visual clarity of the front windshield is often affected by a variety of adverse factors, including rain, snow, dust, oil film, and fog. These visual obstacles not only significantly reduce the driver's field of vision, but also increase the potential safety hazards during driving, especially at night or in severe weather conditions. At present, common solutions include using wipers and glass water to clean the windshield. Wipers can physically remove most of the solid particles and liquids on the surface of the glass, while glass water helps dissolve grease and reduce the surface tension of water droplets, thereby improving the cleaning effect of wipers. Although these methods are relatively effective in daily use, they have some limitations that cannot be ignored. First, the cleaning effect of wipers depends largely on the condition of the wipers themselves and the chemical composition of the glass water. Once the wipers are worn or the glass water formula is poor, the cleaning effect will be greatly reduced. In addition, these traditional methods have a relatively slow response speed, especially in extreme weather conditions, such as foggy or snowy weather, they often find it difficult to quickly and thoroughly remove obstacles on the windshield, thus affecting driving safety.
[0019] In addition, some high-end vehicles are equipped with a front windshield heating system, which can effectively increase the temperature of the glass surface by embedding heating wires in the glass, thereby accelerating the dissipation of frost or fog. This technology has shown relatively good results in improving the clarity of vision, especially in cold winter. However, the main disadvantages of the front windshield heating system are its high cost and complexity of installation. The heating wire needs to be precisely embedded in the glass, a process that not only increases the production cost of the glass, but also may affect the overall strength and durability of the glass. In addition, the energy consumption of this system is relatively high, and long-term use may affect the battery life of the vehicle. Therefore, although the existing technology can solve the problem of unclear vision of the front windshield to a certain extent, there are still problems such as low efficiency and high cost, which limits their application in a wide range of models.
[0020] Based on the above problems, the applicant found that: at least one row / column of multiple air outlets are set on the upper edge, lower edge or side edge of the outside of the vehicle windshield. When it is determined that the windshield needs to be cleaned, the target air outlet and air outlet parameters are determined according to the cleaning requirement type of the windshield; the windshield is cleaned through the target air outlet; by precisely controlling the opening and air outlet parameters of the air outlet, the pollutants on the windshield can be removed in a targeted manner, which not only improves the cleaning efficiency, but also saves energy and the consumption of cleaning materials.
[0021] The embodiments of the present application are described in detail below with reference to the accompanying drawings.
[0022] The present application provides a vehicle windshield cleaning method, such as Figure 1 As shown, in some embodiments, the method is executed by a vehicle controller or a data processor independently provided by the vehicle controller. The subsequent embodiments are all illustrated by taking the vehicle controller as an example. The vehicle includes a plurality of air outlets provided at the outer edge of the windshield. The method includes:
[0023] S101, in response to determining that there is a need to clean the windshield, determining a target air outlet and air outlet parameters according to the type of cleaning requirement of the windshield;
[0024] In specific implementation, the state of the windshield is first monitored by using sensors or visual systems. Sensors may include optical sensors, raindrop detection sensors, or other types of environmental sensors that can assess the degree of contamination on the windshield, such as dust, oil film, rain, snow, or ice. The need for cleaning the windshield can be determined by analyzing sensor data. For example, if the sensor detects a large amount of rain or snow covering the glass, it will be identified that there is a need for cleaning. The type of cleaning requirement can be divided into different levels according to the amount of pollutants on the windshield, such as light, relatively light, moderate, or heavy cleaning requirements. Each type of cleaning requirement is associated with a specific air outlet (target air outlet) and air outlet parameters (such as wind speed, temperature) to effectively deal with different degrees of pollution. For example, the cleaning requirement type is determined according to the occlusion rate of the windshield; the target air outlet and the air outlet parameters of the target air outlet are determined according to the relationship between the cleaning requirement type and the preset cleaning requirement type; the optical sensor can measure the attenuation of light passing through the windshield. When the glass is covered with pollutants, the transmittance will decrease. By comparing the light transmittance under normal conditions (no pollution) and the current situation, the occlusion rate can be estimated. The decrease in transmittance is proportional to the occlusion rate. In the face of severe pollution, it may be necessary to start more air outlets, increase wind speed and outlet temperature to quickly remove pollutants. The choice of air outlet can also be determined based on the specific location of the pollutants. If visual detection shows that the pollutants are mainly concentrated in the driver's line of sight, the air outlets (target air outlets) in that line of sight may be opened first.
[0025] S102: Clean the windshield through the target air outlet.
[0026] In specific implementation, once the target air outlet and air outlet parameters are determined, the corresponding target air outlet will be opened. The target air outlet may be located at the upper edge, lower edge or side edge of the windshield, so as to discharge air in a targeted manner according to the set parameters to exert a cleaning effect on the polluted area, and directly physically clean the windshield. The direct airflow cleaning method can quickly and effectively remove pollutants on the windshield and restore the driver's line of sight. The vehicle can automatically respond to different environmental conditions and the pollution status of the windshield to achieve precise and efficient cleaning operations, thereby ensuring driving safety. It not only improves the reaction speed and cleaning efficiency, but also can be adjusted intelligently according to actual conditions, greatly improving the user experience and the practicality of the vehicle. During the cleaning process, the sensor can continue to monitor the cleaning status of the windshield. If the pollutants are not completely removed after cleaning, the target air outlet and air outlet parameters can be adjusted as needed. Monitoring of the cleaning effect ensures that each cleaning can achieve the expected effect and maintain the optimal line of sight of the windshield.
[0027] In this embodiment, by effectively removing pollutants on the front windshield, such as rain, snow, frost, dust and oil film, the driver can have a good view in all weather conditions. Compared with the traditional windshield wiper and glass water cleaning method, the airflow cleaning directly on the polluted area through the target air outlet can quickly remove pollutants and reduce driving risks caused by unclear vision. By accurately controlling the air outlet and adjusting the air outlet parameters, energy can be used effectively, excessive consumption is avoided, and the battery life of the vehicle is protected.
[0028] In some embodiments, determining the target air outlet and air outlet parameters according to the cleaning requirement type of the windshield includes:
[0029] Determine the type of cleaning requirement based on the windshield occlusion rate;
[0030] In specific implementation, the occlusion rate refers to the ratio of the area covered by pollutants on the windshield to the entire glass area. This includes raindrops, dust, oil film, snow, ice and any other substances that may obstruct vision. Measuring the occlusion rate usually requires the use of high-precision sensors or image processing technology. For example, the image of the windshield is captured by a camera installed on the front of the vehicle, and the coverage of pollutants in the image is analyzed by software; or the attenuation of light passing through the windshield is measured by an optical sensor. When the glass is covered with pollutants, the transmittance will decrease. By comparing the light transmittance in normal conditions (no pollution) and the current situation, the occlusion rate can be estimated. The reduction in transmittance is proportional to the occlusion rate. According to the different levels of occlusion rate, the cleaning needs are classified into different types, such as mild, mild, moderate, severe, etc. Each type corresponds to a different degree of pollution, thus requiring a different cleaning strategy. For example, a light cleaning requirement may correspond to an occlusion rate of 10% to 20%, a lighter cleaning requirement may correspond to an occlusion rate of 20% to 30%, a moderate cleaning requirement corresponds to an occlusion rate between 30% and 40%, and a heavy cleaning requirement corresponds to an occlusion rate of more than 40%.
[0031] The target air outlet and the air outlet parameters of the target air outlet are determined according to the cleaning requirement type and the preset cleaning requirement type relationship.
[0032] In specific implementation, when a specific cleaning requirement type is identified, a preset mapping relationship table of cleaning requirement types and air outlet configurations is referenced to quickly set the corresponding air outlets and air outlet parameters, and determine which air outlet combinations and air outlet parameter settings are more effective under different cleaning requirements. The preset mapping relationship table of cleaning requirement types and air outlet configurations is based on past experience and testing. Each type of cleaning requirement corresponds to one or more specific groups of air outlets. The selection of air outlets is based on their location and capabilities to maximize the cleaning effect. For example, for mild cleaning requirements, only a small portion of the air outlets located at the lower edge of the windshield, such as the lower edge, may need to be opened; while for severe cleaning requirements, more air outlets may need to be opened to cover a larger polluted area. The air outlet parameters include wind speed and temperature. The air outlet parameters will be adjusted according to the type of cleaning requirement to adapt to different degrees of pollution. For mild pollution, a lower wind speed and normal temperature wind may be set; for severe pollution, high wind speed and heated wind may be required to more effectively remove frost or oil film.
[0033] In this embodiment, by accurately measuring the occlusion rate and determining the type of cleaning requirement, it is possible to provide appropriate responses to different degrees of pollution, ensure the pertinence and effectiveness of the cleaning operation, and avoid excessive or insufficient cleaning. By adjusting the air outlet and air outlet parameters (such as wind speed and temperature) according to the specific type of cleaning requirement, pollutants on the windshield can be more effectively removed to quickly restore the driver's vision clarity, especially in severe weather conditions, thereby improving overall driving safety and user experience.
[0034] In some embodiments, determining the cleaning requirement type according to the occlusion rate of the windshield includes:
[0035] In response to the occlusion rate of the windshield being greater than or equal to a first preset occlusion rate and less than a second preset occlusion rate, determining that the cleaning requirement type is a light cleaning requirement;
[0036] In response to the occlusion rate of the windshield being greater than or equal to the second preset occlusion rate and less than the third preset occlusion rate, determining that the cleaning requirement type is a lighter cleaning requirement;
[0037] In response to the occlusion rate of the windshield being greater than or equal to a third preset occlusion rate and less than a fourth preset occlusion rate, determining that the cleaning requirement type is a moderate cleaning requirement;
[0038] In response to the occlusion rate of the windshield being greater than or equal to a fourth preset occlusion rate, it is determined that the cleaning requirement type is a heavy cleaning requirement.
[0039] During specific implementation, multiple preset occlusion rates are set to distinguish different degrees of pollution. The preset occlusion rate can be derived based on experiments and actual driving experience, and can effectively indicate different levels of cleaning needs. When the occlusion rate is greater than or equal to the first preset occlusion rate and less than the second preset occlusion rate (for example, the first preset occlusion rate can be set to 10%, and the second preset occlusion rate can be set to 20%), it is judged as a mild cleaning demand, which is usually suitable for slight dust or a small amount of rain and snow. When the occlusion rate is greater than or equal to the second preset occlusion rate and less than the third preset occlusion rate (for example, the third preset occlusion rate can be set to 30%), it is judged as a relatively mild cleaning demand, which is suitable for moderate amounts of rain and snow or slight mud pollution. When the occlusion rate is greater than or equal to the third preset occlusion rate and less than the fourth preset occlusion rate (for example, the fourth preset occlusion rate can be set to 40%), it is judged as a moderate cleaning demand, and more serious pollution may need to be handled, such as thicker mud or slight frost. When the obstruction rate is equal to or exceeds a fourth preset obstruction rate, it is determined as a severe cleaning requirement, which usually involves a serious pollution situation, such as thick ice, oil film, or a large amount of mud.
[0040] In this embodiment, by clearly defining different preset occlusion rates, the pollution degree of the windshield can be accurately determined, so as to be more targeted and ensure that each pollution condition is properly handled. By adjusting the air outlet and air outlet parameters, such as wind speed and temperature, according to different cleaning needs, cleaning resources can be used effectively to avoid resource waste.
[0041] In some embodiments, determining the target air outlet and the air outlet parameters of the target air outlet according to the cleaning requirement type and the preset cleaning requirement type relationship includes:
[0042] In response to determining that the cleaning requirement type is a heavy cleaning requirement, a first preset number of air outlets extending from the air outlet corresponding to the main driving position to both sides and covering the air outlets are determined as target air outlets, and the wind speed is the first preset wind speed, and the air outlet temperature is the first preset temperature;
[0043] In response to determining that the cleaning requirement type is a moderate cleaning requirement, a second preset number of air outlets extending from the air outlet corresponding to the main driving position to both sides and covering the air outlets are determined as target air outlets, and the wind speed is the second preset wind speed, and the air outlet temperature is the second preset temperature;
[0044] In response to determining that the cleaning requirement type is a relatively mild cleaning requirement, a third preset number of air outlets extending from the air outlet corresponding to the main driving position to both sides and covered are determined as target air outlets, and the wind speed is the third preset wind speed, and the air outlet temperature is the third preset temperature;
[0045] In response to determining that the cleaning requirement type is a light cleaning requirement, a fourth preset number of air outlets extending from the air outlet corresponding to the main driving position to both sides and covered are determined as target air outlets, and the wind speed is the fourth preset wind speed, and the air outlet temperature is the fourth preset temperature;
[0046] Among them, the first preset number is greater than the second preset number, the second preset number is greater than the third preset number, the third preset number is greater than the fourth preset number, the first preset wind speed is greater than the second preset wind speed, the second preset wind speed is greater than the third preset wind speed, the third preset wind speed is greater than the fourth preset wind speed, the first preset temperature is greater than the second preset temperature, the second preset temperature is greater than the third preset temperature, and the third preset temperature is greater than the fourth preset temperature.
[0047] In specific implementation, the corresponding number of air outlets is selected according to the severity of the cleaning needs (mild, mild, moderate, severe). These air outlets start from the air outlet corresponding to the main driving position and extend to both sides to cover a wider area to deal with a wider range of pollution. For example, for severe cleaning needs, more air outlets are needed, which cover a larger area extending from the main driving position to both sides to ensure sufficient cleaning strength and coverage. Exemplarily, the first preset number can be set to 100% of the number of vehicle air outlets, the second preset number can be set to 80% of the number of vehicle air outlets, the third preset number can be set to 60% of the number of vehicle air outlets, and the fourth preset number can be set to 40% of the number of vehicle air outlets; the first preset wind speed can be set to 100% of the maximum wind speed of the air outlet, the second preset wind speed can be set to 80% of the maximum wind speed of the air outlet, the third preset wind speed can be set to 60% of the maximum wind speed of the air outlet, and the fourth preset wind speed can be set to 40% of the maximum wind speed of the air outlet; the first preset temperature can be set to 100% of the maximum air outlet temperature of the air outlet, the second preset temperature can be set to 80% of the maximum air outlet temperature of the air outlet, the third preset temperature can be set to 60% of the maximum air outlet temperature of the air outlet, and the fourth preset temperature can be set to 40% of the maximum air outlet temperature of the air outlet. The wind speed and air outlet temperature are adjusted according to the severity of the cleaning demand. Stronger cleaning demands usually require higher wind speeds and higher temperatures to quickly remove stubborn pollutants, such as frost or thick mud. As the level of cleaning demand decreases, the wind speed and temperature are reduced accordingly to avoid unnecessary pressure or damage to the windshield and save energy. Through this refined control strategy, it can effectively respond to various pollution situations, ensure the driver's clear vision, thereby improving driving safety, not only improving cleaning efficiency, but also reducing energy consumption by intelligently adjusting the air outlet parameters, enhancing the economy and environmental protection of the system.
[0048] In this embodiment, by adjusting the number and position of the air outlets, as well as the wind speed and temperature according to different types of cleaning needs (mild, relatively mild, moderate, and severe), cleaning can be more accurately targeted to the degree of pollution, ensuring that each pollution situation is properly handled. By avoiding excessive use of wipers and other mechanical parts, it helps to reduce the wear and maintenance requirements of these parts. In the long run, this can extend the service life of the equipment and reduce maintenance costs. Through refined control based on the type of cleaning needs, not only the accuracy and efficiency of the operation are improved, but also the use of resources is optimized, driving safety is enhanced, and the overall user experience is improved.
[0049] In some embodiments, Figure 2 As shown, the cleaning of the windshield through the target air outlet also includes:
[0050] S201, obtaining the remaining energy ratio of the vehicle;
[0051] In specific implementation, the energy remaining ratio refers to the ratio of the vehicle's currently available energy (such as battery power or fuel remaining) to the vehicle's fully charged energy state. The current energy remaining ratio is obtained through the vehicle's energy management system, which usually involves real-time monitoring of the vehicle's battery power or fuel gauge readings, and calculating its percentage of the full state. In electric vehicles, this may involve obtaining data from the battery management system (BMS), while in fuel vehicles, this may involve obtaining data from the fuel sensor.
[0052] S202A, in response to determining that the remaining energy ratio is greater than or equal to a preset remaining energy ratio, opening all target air outlets to clean the windshield;
[0053] In specific implementation, when the remaining energy ratio is sufficient, that is, the remaining energy ratio is greater than or equal to the preset remaining energy ratio (exemplarily, the preset remaining energy ratio can be set to 60%), all target air outlets on the windshield are started to ensure that pollutants such as dust, raindrops, snowflakes or oil films can be removed to ensure that the driver's vision maintains optimal clarity under all weather and road conditions.
[0054] S202B, in response to determining that the remaining energy ratio is less than a preset remaining energy ratio, opening the target air outlet corresponding to the main driving position to clean the windshield and determining whether the occlusion rate of the windshield is reduced;
[0055] In specific implementation, when the remaining energy ratio is insufficient, that is, the remaining energy ratio is less than the preset remaining energy ratio, the target air outlet corresponding to the main driving position is opened to clean the windshield and determine whether the occlusion rate of the windshield is reduced, giving priority to energy saving, so all target air outlets will not be fully opened. On the contrary, only the target air outlet corresponding to the main driving position is opened, which is usually the most critical line of sight area, to ensure that the driver's forward field of vision is as clear as possible, which helps to reduce energy consumption and meet basic safety needs. After opening the target air outlet corresponding to the main driving position for cleaning, the occlusion rate of the windshield will continue to be monitored, and the cleaning status of the windshield will be analyzed in real time. While ensuring the driver's clear line of sight, it can effectively manage the vehicle's energy consumption, improve the adaptability and reliability of the vehicle system, and ensure that good driving conditions can be maintained under various energy conditions.
[0056] S203: In response to determining that the occlusion rate of the windshield is reduced, opening the remaining target air outlets to clean the windshield.
[0057] In specific implementation, only the target air outlets corresponding to the main driver's position are activated for preliminary cleaning at first, aiming to prioritize clearing the occlusion of the driver's field of vision when energy is limited. Once the occlusion rate is confirmed to be reduced through this local cleaning operation, it is considered that there is sufficient evidence to show that further cleaning is necessary and the improvement of vision will be effective. After confirming that the occlusion rate has been reduced, the remaining target air outlets will be opened. To cover other key areas of the windshield, including the co-pilot side and a wider front view area, to further enhance the cleaning effect and ensure the overall transparency of the windshield and driving safety. It helps to protect the vehicle's energy supply, especially when the battery is low or the fuel is insufficient, to ensure that the vehicle can remain in operation for longer, to minimize the demand for energy while ensuring safety, to effectively manage the cleaning of the windshield under different energy states, to ensure driving safety, while optimizing energy use and improving overall vehicle efficiency and reliability.
[0058] In this embodiment, the scope of the cleaning operation is determined by considering the remaining energy ratio of the vehicle, which helps to optimize energy use, ensure comprehensive cleaning when energy is sufficient, and take energy-saving measures when energy is low, giving priority to ensuring the clarity of key visual areas, enhancing adaptability to different driving and energy conditions, and improving the reliability and practicality of the vehicle.
[0059] In some embodiments, Figure 3 As shown, the opening of the remaining target air outlets to clean the windshield includes:
[0060] S301, determining a reduction rate of the occlusion rate;
[0061] In specific implementation, the rate of reduction of the occlusion rate refers to the degree of reduction of the occlusion rate on the windshield within a certain period of time, which is usually calculated by comparing two consecutive (or more) occlusion rate measurement results; the calculation of the rate of reduction of the occlusion rate can be expressed as: (initial occlusion rate-current occlusion rate) / time interval.
[0062] S302A, in response to the reduction rate being less than a preset reduction rate, extending from the target air outlet corresponding to the main driving position to both sides to sequentially open the remaining target air outlets;
[0063] In specific implementation, when the reduction rate of the occlusion rate does not reach the preset standard, that is, the reduction rate is less than the preset reduction rate (for example, the preset reduction rate can be set to reduce by 10% per minute), it indicates that the current cleaning effect is not enough to quickly remove pollutants on the windshield. In order to improve the cleaning efficiency, more air outlets are gradually opened to increase the cleaning range. Starting from the air outlet corresponding to the main driving position, the air outlets are gradually extended to both sides to open because the main driving position is usually the most critical line of sight area, and its cleaning needs to be prioritized. Then gradually expanding to both sides can evenly improve the cleaning effect of the entire windshield.
[0064] S302B: in response to the reduction rate being greater than or equal to a preset reduction rate, all remaining target air outlets are opened simultaneously.
[0065] In specific implementation, if the rate of reduction of the occlusion rate is greater than or equal to the preset rate of reduction, it indicates that the initial cleaning measures are very effective and the pollutants on the windshield are being removed at a faster rate than or equal to the expected rate. In this case, it is judged that the cleaning process can be completed faster, so it is decided to start all the remaining target air outlets at the same time. Opening all the remaining target air outlets at the same time can significantly increase the scope of the cleaning effect, help to quickly reduce the occlusion rate on the windshield, thereby restoring the driver's vision clarity more quickly, and provide a large amount of cleaning capacity in a short time. Especially when encountering heavy pollution, it can effectively reduce the total time required for cleaning; it can optimize energy utilization and time management while ensuring efficient cleaning, and improve overall efficiency and user driving experience.
[0066] In this embodiment, by monitoring the reduction rate of the occlusion rate in real time and adjusting the cleaning strategy based on the comparison result with the preset reduction rate, it can dynamically respond to the actual cleaning needs of the windshield, ensuring that the cleaning operation always matches the current pollution conditions; it helps to avoid unnecessary waste of energy and resources, not only improves energy efficiency, but also reduces operating costs.
[0067] In some embodiments, determining that the windshield needs to be cleaned includes:
[0068] Get the occlusion rate of the windshield;
[0069] In specific implementation, the occlusion rate is a quantitative indicator to measure the degree of coverage of pollutants on the windshield. It reflects the severity of the obstruction of the view on the windshield and is the basis for judging the urgency of cleaning. Obtaining the occlusion rate usually requires the use of high-precision sensors or image processing technology. For example, the image of the windshield is captured by a camera installed on the front of the vehicle, and the coverage of pollutants in the image is analyzed by software; or the attenuation of light passing through the windshield is measured by an optical sensor. When the glass is covered with pollutants, the transmittance will decrease. By comparing the light transmittance in normal conditions (no pollution) and the current situation, the occlusion rate can be estimated. The reduction in transmittance is proportional to the occlusion rate.
[0070] In response to determining that the blocking ratio is greater than or equal to a first preset blocking ratio, it is determined that there is a need to clean the windshield.
[0071] In specific implementation, when it is determined that the occlusion rate is greater than or equal to a first preset occlusion rate (for example, the first preset occlusion rate can be set to 10%), it is determined that the windshield needs to be cleaned. The first preset occlusion rate represents a safe limit for the coverage of pollutants on the windshield, exceeding which may affect the driver's line of sight and the safe operation of the vehicle. The determination of the preset occlusion rate usually takes into account a variety of factors, including the design of the vehicle, the use environment, typical weather conditions, and driving safety regulations.
[0072] In this embodiment, by setting a preset occlusion rate as the trigger point for cleaning requirements, cleaning can be actively performed before the occlusion rate reaches a level that may affect the driver's vision, thereby ensuring that the driver has a clear field of vision at all times. Triggering the cleaning operation based on the actual occlusion rate can avoid unnecessary frequent cleaning, save cleaning resources, and also avoid potential damage to the windshield due to excessive cleaning.
[0073] In some embodiments, the windshield includes a front windshield and a rear windshield; in response to determining that there is a need to clean the windshield, determining a target air outlet and air outlet parameters according to the type of cleaning requirement of the windshield includes:
[0074] In response to determining that there is a need to clean the front windshield, determining a target air outlet and air outlet parameters according to the type of cleaning requirement for the front windshield;
[0075] In specific implementation, the status of the windshield is first monitored by using sensors or visual systems. Sensors may include optical sensors, raindrop detection sensors, or other types of environmental sensors that can assess the degree of contamination on the windshield, such as dust, oil film, rain, snow, or ice. The need for cleaning the windshield can be determined by analyzing sensor data. For example, if the sensor detects a large amount of rain or snow covering the glass, it will be identified that there is a need for cleaning. The type of cleaning requirement can be divided into different levels according to the amount of pollutants on the windshield, such as light, relatively light, moderate, or heavy cleaning requirements. Each type of cleaning requirement is associated with a specific air outlet (target air outlet) and air outlet parameters (such as wind speed, temperature) to effectively deal with different degrees of pollution.
[0076] The method further comprises:
[0077] In response to determining that there is a need to clean the rear windshield, a fifth preset number of air outlets corresponding to the middle area of the rear windshield are determined as target air outlets.
[0078] In specific implementation, similar to the front windshield, the cleaning demand of the rear windshield is usually based on the measurement of the occlusion rate. When the occlusion rate exceeds the preset safety threshold (such as the first preset occlusion rate), it is determined that the rear windshield needs to be cleaned. The middle area of the rear windshield is usually the most critical sight area because it directly affects the driver's ability to observe the rear traffic conditions through the rearview mirror. At this time, the fifth preset number of air outlets corresponding to the middle area of the rear windshield are determined as the target air outlets (exemplarily, the fifth preset number can be set to 50% of the number of air outlets of the vehicle) to clean the rear windshield. By precisely controlling the cleaning of the middle area of the rear windshield, the driver can maintain a clear rear view and avoid vehicle collisions and other safety accidents.
[0079] In this embodiment, by ensuring the cleanliness of the front windshield and the rear windshield, the driver's front and rear vision can be kept clear, especially the cleanliness of the rear windshield, which directly affects the driver's ability to observe the traffic conditions behind through the rearview mirror, provides a flexible and efficient cleaning solution under different driving conditions, and enhances the overall performance of the vehicle and user satisfaction.
[0080] It should be noted that the method of the embodiment of the present application can be performed by a single device, such as a computer or server. The method of this embodiment can also be applied to a distributed scenario and completed by multiple devices cooperating with each other. In the case of such a distributed scenario, one of the multiple devices can only perform one or more steps in the method of the embodiment of the present application, and the multiple devices will interact with each other to complete the described method.
