Description

Technical Field

[0001] This application relates to the field of automotive intelligent control technology, and in particular to a vehicle cooling method, system, and vehicle. Background Technology

[0002] After a vehicle has been parked outdoors for a long time in hot weather, the interior temperature may reach as high as 50 degrees Celsius. At this temperature, passengers will experience severe discomfort after getting into the vehicle and will need to wait until the interior temperature is suitable before they can perform any subsequent operations, such as driving the vehicle.

[0003] To address this issue, some car models on the market are equipped with the function of remotely turning on the air conditioning via a mobile phone, or turning on the air conditioning at specific times based on the settings pre-stored in the user's mobile phone or the car's system, so that passengers can feel a relatively comfortable temperature after getting into the car.

[0004] However, it is clear that the technical solutions currently available on the market require users to operate them manually after they have learned the corresponding functions. This makes them difficult to learn and lacks flexibility, making it impossible for every user to feel a relatively comfortable temperature when they get into the vehicle at any time. Summary of the Invention

[0005] In view of this, this application provides a vehicle cooling method that can rapidly cool the vehicle after a user gets in, the method comprising: When the vehicle controller determines that the preset conditions are met, it uses the window control unit to control all windows and the sunroof to be fully opened and maintained for a first preset time. The preset conditions include the body control module detecting that the vehicle has been unlocked and at least one of the driver's and passenger's doors has been opened, and the interior temperature sensor detecting that the current interior temperature is greater than the first preset temperature.

[0006] In some optional embodiments, the preset conditions also include: The rain sensor detected no rainfall at present.

[0007] In some optional embodiments, the method further includes: The wind sensor acquires the current ambient wind force and transmits it to the vehicle controller.

[0008] The vehicle controller determines the opening degree corresponding to the current ambient wind force based on the preset relationship between wind force and opening degree, and uses the window control unit to open all windows and sunroof to the desired opening degree and maintain it for a first preset time. In the preset relationship between wind force and opening degree, wind force and opening degree are negatively correlated.

[0009] In some optional embodiments, the method further includes: The vehicle controller uses the window control unit to control all windows and sunroof to be fully opened and maintained for a first preset time. If the outside temperature sensor determines that the outside temperature is lower than the second preset temperature, the vehicle controller turns on the air conditioner and switches to external circulation mode, adjusts the air volume to the maximum, and keeps the air conditioner compressor off. The second preset temperature is lower than the first preset temperature.

[0010] In some optional embodiments, after the vehicle controller uses the window control unit to control all windows and sunroof to be fully opened and maintained for a first preset time, the method further includes: The vehicle controller uses the window control unit to control the closing of all windows and the sunroof. The vehicle controller turns on the air conditioning and switches to the internal circulation mode, sets the air volume to the maximum, and keeps the air conditioning compressor running.

[0011] On the other hand, this application also provides a vehicle cooling system, which includes a vehicle controller, a body control module, an in-vehicle temperature sensor, and a window control unit, wherein: The vehicle controller is configured to, when it determines that preset conditions are met, use the window control unit to control all windows and sunroof to be fully opened and maintained for a first preset time. The preset conditions include the body control module detecting that the vehicle is unlocked and at least one of the driver's and passenger's doors is opened, and the interior temperature sensor detecting that the current interior temperature is greater than the first preset temperature.

[0012] In some optional embodiments, the system further includes a rain sensor, and the preset conditions also include: The rain sensor detected no rainfall at present.

[0013] In some optional embodiments, the system also includes a wind sensor configured to acquire the current ambient wind speed and transmit it to the vehicle controller.

[0014] The vehicle controller is configured to determine the opening degree corresponding to the current ambient wind force based on a pre-stored preset relationship between wind force and opening degree, and to open all windows and sunroof to the desired opening degree using the window control unit and maintain it for a first preset time. In the pre-stored preset relationship between wind force and opening degree, wind force and opening degree are negatively correlated.

[0015] In some optional embodiments, the system also includes an outside temperature sensor, and the vehicle controller is further configured to, while using the window control unit to control all windows and sunroof to be fully opened and maintained for a first preset time, if the outside temperature sensor determines that the outside temperature is lower than a second preset temperature, turn on the air conditioner and switch to external circulation mode, adjust the air volume to the maximum, and keep the air conditioner compressor off, wherein the second preset temperature is lower than the first preset temperature.

[0016] The vehicle controller is also configured to, after using the window control unit to fully open all windows and sunroof and maintain them for a first preset time, use the window control unit to close all windows and sunroof, turn on the air conditioning and switch to recirculation mode, set the air volume to maximum, and keep the air conditioning compressor running.

[0017] In another aspect, this application also provides a vehicle including the vehicle cooling system provided in the foregoing.

[0018] Using the vehicle cooling method provided in this application, when the vehicle controller determines that the vehicle has been unlocked and at least one of the driver's or passenger's doors has been opened (i.e., the vehicle is not armed and passengers need to get in), and the in-vehicle temperature sensor detects that the current in-vehicle temperature is high), it directly lowers all the windows completely and opens the sunroof completely. This allows for rapid exchange between the hot air inside the vehicle and the outside air, removing heat from the vehicle and quickly cooling the interior temperature. This enables users unfamiliar with remote air conditioning control to experience a relatively comfortable temperature after getting in the vehicle, improving the adaptability of the solution and enhancing the user experience.

Detailed Implementation

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Currently, some mid-to-high-end models are equipped with "remote start air conditioning" or "pre-ventilation" functions, and common implementation methods include: 1. Timed ventilation mode: The user presets a time to start the fan for ventilation, but it cannot be dynamically adjusted according to the real-time temperature and humidity environment.

[0023] 2. Remote APP control of air conditioner: The air conditioner can be remotely started via a mobile APP (such as BYD, NIO and other brands). This requires active operation by the user and has a limited level of intelligence.

[0024] 3. Sunlight sensor linked to air conditioning: The system uses light intensity to determine the temperature rise trend inside the car and activates the air conditioning (as in some Toyota models), but it does not respond to the door opening behavior in a contextualized manner.

[0025] 4. Automatic Window Lowering on One Side: A few models automatically lower the driver's side window when unlocking, mainly for emergency entry in situations where the key is forgotten. It does not have a full vehicle ventilation function.

[0026] The above-mentioned solutions generally suffer from problems such as reliance on human intervention, poor environmental adaptability, and poor suitability.

[0027] Therefore, there is an urgent need for a control method that can automatically sense user intentions, comprehensively judge environmental conditions, and intelligently execute vehicle ventilation to improve driving comfort and intelligence.

[0028] This application provides a vehicle cooling method, such as... Figure 1 As shown, this method can be executed by the vehicle controller, and the method includes step S101: In step S101, when the vehicle controller determines that the preset conditions are met, it uses the window control unit to control all windows and sunroof to be fully opened and maintained for a first preset time. The preset conditions include the body control module detecting that the vehicle is unlocked and at least one of the driver's and passenger's doors is opened, and the in-vehicle temperature sensor detecting that the current in-vehicle temperature is greater than the first preset temperature.

[0029] In some optional embodiments, the preset conditions also include: The rain sensor detected no rainfall at present.

[0030] In some optional embodiments, the method further includes: The wind sensor acquires the current ambient wind force and transmits it to the vehicle controller.

[0031] The vehicle controller determines the opening degree corresponding to the current ambient wind force based on the preset relationship between wind force and opening degree, and uses the window control unit to open all windows and sunroof to the desired opening degree and maintain it for a first preset time. In the preset relationship between wind force and opening degree, wind force and opening degree are negatively correlated.

[0032] In some optional embodiments, the method further includes: The vehicle controller uses the window control unit to control all windows and sunroof to be fully opened and maintained for a first preset time. If the outside temperature sensor determines that the outside temperature is lower than the second preset temperature, the vehicle controller turns on the air conditioner and switches to external circulation mode, adjusts the air volume to the maximum, and keeps the air conditioner compressor off. The second preset temperature is lower than the first preset temperature.

[0033] In some optional embodiments, after the vehicle controller uses the window control unit to control all windows and sunroof to be fully opened and maintained for a first preset time, the method further includes: The vehicle controller uses the window control unit to control the closing of all windows and the sunroof. The vehicle controller turns on the air conditioning and switches to the internal circulation mode, sets the air volume to the maximum, and keeps the air conditioning compressor running.

[0034] The vehicle cooling method provided in this application involves the vehicle controller determining, through the body control module, that the vehicle is unlocked and at least one of the driver's or passenger's doors is open, indicating that the vehicle is not armed and passengers need to get in. When the in-vehicle temperature sensor detects a high in-vehicle temperature, all windows are fully lowered and the sunroof is fully opened. This allows for rapid exchange of hot air inside the vehicle with outside air, carrying away heat and quickly cooling the vehicle's interior. This enables users unfamiliar with remote air conditioning control to experience a relatively comfortable temperature after getting in, improving the adaptability of the solution and enhancing the user experience.

[0035] This application also provides a vehicle cooling method, such as... Figure 2 As shown, this method can be executed by the vehicle controller, and includes steps S201 and S202: In step S201, when the vehicle controller determines that the preset conditions are met, it uses the window control unit to control all windows and the sunroof to be fully opened and maintained for a first preset time. The preset conditions include the body control module detecting that the vehicle is unlocked and at least one of the driver's and passenger's doors is opened, and the in-vehicle temperature sensor detecting that the current in-vehicle temperature is greater than the first preset temperature.

[0036] In step S202, the vehicle controller uses the window control unit to control all windows and sunroof to be fully opened and maintained for a first preset time. If the outside temperature sensor determines that the outside temperature is lower than the second preset temperature, the vehicle controller turns on the air conditioner and switches to external circulation mode, adjusts the air volume to the maximum, and keeps the air conditioner compressor off, wherein the second preset temperature is lower than the first preset temperature.

[0037] It is understandable that if the temperature inside the vehicle is too high, simply opening the windows may not be sufficient to achieve a good and rapid ventilation effect. Therefore, the method described in step S202, which involves turning on the air conditioning's external circulation while keeping the compressor off, can also be used to enhance the cooling effect. Thus, in some optional embodiments, as a parallel step to step S202, the method may further include: The vehicle controller uses the window control unit to control all windows and sunroof to be fully opened and maintained for a first preset time. If the in-vehicle temperature sensor detects that the current in-vehicle temperature is higher than the third preset temperature, the vehicle controller turns on the air conditioner and switches to external circulation mode, adjusts the air volume to the maximum, and keeps the air conditioner compressor off. The third preset temperature is higher than the first preset temperature.

[0038] The first preset temperature can be 25 degrees or 40 degrees.

[0039] When the first preset temperature is 25 degrees, the third preset temperature can be 40 degrees, and the second preset temperature can be 20 degrees.

[0040] When the first preset temperature is 40 degrees, the third preset temperature can be 50 degrees, and the second preset temperature can be 25 degrees.

[0041] In some optional embodiments, the vehicle controller turns on the air conditioning and switches to external circulation mode, sets the air volume to the maximum, and keeps the air conditioning compressor off while setting the air conditioning temperature to the lowest setting.

[0042] In some optional embodiments, the condition "the vehicle control module detects that the vehicle is unlocked and at least one of the driver's and passenger's doors is opened" included in the preset conditions can be replaced with a condition with a specific sequence, such as the vehicle control module detecting that the vehicle is unlocked and at least one of the driver's and passenger's doors being opened within a preset time window after the vehicle is unlocked, which can be 30 seconds.

[0043] Understandably, in order to accurately predict whether passengers need to get into the vehicle, windows should be opened as early as possible to improve ventilation and cooling, so that passengers can feel a relatively comfortable temperature after opening the car door and entering the vehicle. In some optional embodiments, the preset conditions may only include the following first prediction condition, without determining whether the driver's and passenger's doors are opened: The vehicle control module detected that the key fob unlock button was pressed, and the interior temperature sensor detected that the current interior temperature was higher than the first preset temperature. It's understandable that if the occupant only wanted to retrieve items from the trunk, they would most likely only press the trunk unlock button on the key fob or the physical unlock button on the trunk. Therefore, detecting that the key fob unlock button was pressed can accurately predict whether the occupant needs to get into the vehicle.

[0044] In some optional embodiments, the preset conditions may include only the following second pre-judgment condition, without determining whether the driver's and passenger's doors are opened: The vehicle control module detected that the key unlock button was pressed, and determined that the key was less than a preset distance from the vehicle. Furthermore, the interior temperature sensor detected that the current interior temperature was higher than a first preset temperature. Understandably, by confirming that the key is less than a preset distance from the vehicle, it can more accurately predict whether an occupant intends to get in the car, preventing accidental activation of the key unlock button, and also ensuring the safety of valuables inside the vehicle if the windows are opened.

[0045] To ensure safety, in some optional embodiments, if the preset conditions only include the aforementioned first or second pre-judgment condition, without determining whether the driver and passenger doors are opened, the vehicle controller will continuously monitor whether the driver and passenger doors are opened and the distance between the car key and the vehicle (i.e., whether the car key is within a preset radius around the vehicle) during the process of controlling all windows and the sunroof to be fully open and maintained for a first preset time using the window control unit. If the driver and passenger doors are not detected to be opened after the first preset time has been completed, or if the car key is detected to have left the preset radius around the vehicle during the process of controlling all windows and the sunroof to be fully open and maintained for a first preset time, then the window control unit will close all windows and the sunroof to ensure the safety of valuables inside the vehicle.

[0046] It is understandable that opening all car windows and the sunroof during rain could allow rainwater to enter the vehicle, potentially damaging electrical appliances or valuables inside. Therefore: In some optional embodiments, the preset conditions also include: The rain sensor detected no rainfall at present.

[0047] In other words, the window control unit will only fully open and maintain the windows and sunroof for a first preset time when the vehicle controller determines that the following conditions are met: The vehicle control module detected that the vehicle was unlocked and at least one of the driver's and passenger's doors was opened. The rain sensor detected that there was no rain at present, and the interior temperature sensor detected that the current interior temperature was higher than the first preset temperature.

[0048] In some optional embodiments, the preset condition may also be that the rain sensor detects no rainfall based on the first prediction condition described above, or that the rain sensor detects no rainfall based on the second prediction condition described above.

[0049] Understandably, if the preset conditions include rainfall-related factors, then the window opening strategy can be flexibly determined based on different rainfall amounts. In some alternative embodiments, when the rain sensor detects that there is no rain, the window control unit controls all windows and the sunroof to be fully opened and maintained for a first preset time.

[0050] In some optional embodiments, when the rain sensor detects that the current rainfall is greater than zero but less than a first preset rainfall, the window control unit controls all windows to open to a preset degree and maintain this opening for a first preset time, while keeping the sunroof closed. The preset opening degree can be one-third, meaning the window is only partially open. It's important to understand that "window" refers to the vehicle's side windows, not the sunroof. In very light rainfall, opening only a small portion of the side windows will not result in a large amount of water entering the vehicle. Therefore, in very light rainfall, the side windows can be opened only slightly, while the sunroof remains closed, thus improving cooling efficiency while ensuring the safety of items inside the vehicle.

[0051] In some optional embodiments, the method further includes: The wind sensor acquires the current ambient wind force and transmits it to the vehicle controller. In some alternative embodiments, the current ambient wind speed can also be obtained by querying the network using an in-vehicle media system.

[0052] The vehicle controller determines the opening degree corresponding to the current ambient wind force based on the preset relationship between wind force and opening degree, and uses the window control unit to open all windows and sunroof to the desired opening degree and maintain it for a first preset time. In the preset relationship between wind force and opening degree, wind force and opening degree are negatively correlated.

[0053] It's understandable that when the outside wind is strong, even if the car windows are only partially open, good ventilation and cooling can still be achieved. Moreover, if the outside wind is strong and the car windows are fully open, it may blow away items inside the car, even lighter items, or cause dust to accumulate quickly inside the car. Therefore, setting the relationship between wind force and window opening to a negative correlation can improve the ventilation and cooling effect while ensuring the safety and cleanliness of items inside the car.

[0054] Depending on the angular relationship between the vehicle's orientation and the wind direction in its environment, the effectiveness of opening windows for ventilation and cooling will vary. Therefore, in some optional embodiments, the method may further include: When the vehicle controller determines that the preset conditions are met, it uses the vehicle navigation system to obtain the current vehicle orientation and the vehicle media system to obtain the current weather information, including the current wind direction.

[0055] The vehicle controller calculates the angle between the current vehicle orientation and the current wind direction.

[0056] When the angle is less than the preset angle, it means that the angle between the vehicle and the wind direction is relatively small, and the vehicle is facing the wind head-on or rear-facing. In this case, the window control unit will control all windows and sunroof to be fully opened and maintained for the first preset time. By utilizing Bernoulli's principle (the wind force outside the car is greater than inside the car, and the pressure outside the car is less than inside the car at the window), more windows will be used to extract the hot air inside the car more quickly.

[0057] When the angle is greater than the preset angle, it means that the angle between the vehicle and the wind direction is relatively large, and the vehicle is facing the wind from the side. At this time, the window control unit is used to control the left front window and the right rear window to be fully opened and maintained for the first preset time, or the window control unit is used to control the right front window and the left rear window to be fully opened and maintained for the first preset time, thereby using fewer windows to accelerate air convection and blow the hot air inside the car out faster.

[0058] Understandably, if occupants are sensitive to wind noise or dislike the feeling of wind blowing directly on their faces, consideration can be given to avoiding direct wind blowing on their faces while providing ventilation and cooling. Therefore, in some optional embodiments, when the vehicle controller determines that preset conditions are met, it uses the body control module to determine which door is being opened. When the driver's door is opened, the window control unit controls the right front window and left rear window to fully open and remain open for a first preset time; or, when the passenger door is opened, the window control unit controls the left front window and right rear window to fully open and remain open for a first preset time. This achieves ventilation and cooling while avoiding directly opening the side window closest to the occupant, thus preventing direct wind blowing on the occupant.

[0059] The above situation corresponds to the case where the vehicle is a left-hand drive vehicle. In some optional embodiments, when the vehicle is a right-hand drive vehicle, the window opening strategy can be completely opposite to that of the left-hand drive vehicle. That is, when the driver's door is opened, the window control unit controls the left front window and the right rear window to be fully opened and kept open for a first preset time. Alternatively, when the passenger door is opened, the window control unit controls the right front window and the left rear window to be fully opened and kept open for a first preset time. This achieves ventilation and cooling while avoiding directly opening the side window closest to the occupant and preventing the wind from blowing directly on the occupant.

[0060] In some optional embodiments, after the vehicle controller uses the window control unit to control all windows and sunroof to be fully opened and maintained for a first preset time, the method further includes: The vehicle controller uses the window control unit to control the closing of all windows and the sunroof. The vehicle controller turns on the air conditioning and switches to the internal circulation mode, sets the air volume to the maximum, and keeps the air conditioning compressor running.

[0061] In some optional embodiments, the method further includes: The vehicle controller uses the window control unit to control the closing of all windows and the sunroof. The vehicle controller turns on the air conditioning and switches it to the internal circulation mode, sets the air volume to the maximum, sets the air conditioning temperature to the minimum, and keeps the air conditioning compressor running.

[0062] The vehicle cooling method provided in this application involves the vehicle controller determining, via the body control module, that the vehicle is unlocked and at least one of the driver's or passenger's doors is open (meaning the vehicle is not armed and passengers need to get in), and the in-vehicle temperature sensor detects a high in-vehicle temperature. In this case, all windows are fully lowered and the sunroof is fully opened. Furthermore, when the outside temperature is lower than the inside temperature, the air conditioning is turned on and switched to external circulation mode, with the fan speed set to maximum and the air conditioning compressor kept off. This allows for rapid exchange of hot air inside and outside the vehicle without significantly increasing energy consumption, removing heat and quickly cooling the interior. Ultimately, this allows users unfamiliar with remote air conditioning control to experience a relatively comfortable temperature after entering the vehicle, improving the adaptability of the solution and enhancing the user experience.

[0063] This application also provides a vehicle cooling system, such as... Figure 3 As shown, the system includes a vehicle controller 301, a body control module 302, an in-vehicle temperature sensor 303, and a window control unit 304, wherein: The vehicle controller 301 is configured to, when it determines that preset conditions are met, use the window control unit 304 to control all windows and sunroof to be fully opened and maintained for a first preset time. The preset conditions include the body control module 302 detecting that the vehicle is unlocked and at least one of the driver's and passenger's doors is opened, and the interior temperature sensor 303 detecting that the current interior temperature is greater than the first preset temperature.

[0064] In some optional embodiments, the system also includes an outside temperature sensor 307, and the vehicle controller 301 is further configured to, while using the window control unit 304 to control all windows and sunroof to be fully opened and maintained for a first preset time, if the outside temperature sensor 307 determines that the outside temperature is lower than a second preset temperature, turn on the air conditioner and switch to external circulation mode, adjust the air volume to the maximum, and keep the air conditioner compressor off, wherein the second preset temperature is lower than the first preset temperature.

[0065] Understandably, if the interior temperature is too high, simply opening the windows may not be sufficient to achieve a good and rapid ventilation effect. Therefore, the cooling effect can be enhanced by turning on the air conditioning's external circulation mode and keeping the compressor off. Thus, in some optional embodiments, the vehicle controller 301 uses the window control unit 304 to control all windows and the sunroof to be fully open and maintained for a first preset time. If the interior temperature sensor 303 detects that the current interior temperature is higher than a third preset temperature, the vehicle controller 301 turns on the air conditioning and switches to external circulation mode, sets the airflow to maximum, and keeps the air conditioning compressor off, where the third preset temperature is higher than the first preset temperature.

[0066] The first preset temperature can be 25 degrees or 40 degrees.

[0067] When the first preset temperature is 25 degrees, the third preset temperature can be 40 degrees, and the second preset temperature can be 20 degrees.

[0068] When the first preset temperature is 40 degrees, the third preset temperature can be 50 degrees, and the second preset temperature can be 25 degrees.

[0069] In some optional embodiments, the vehicle controller 301 turns on the air conditioner and switches it to external circulation mode, sets the air volume to the maximum, and keeps the air conditioner compressor off while also setting the air conditioner temperature to the lowest setting.

[0070] In some optional embodiments, the condition "the vehicle control module 302 detects that the vehicle is unlocked and at least one of the driver's and passenger's doors is opened" included in the preset conditions can also be replaced with a condition with a specific sequence, such as the vehicle control module 302 detecting that the vehicle is unlocked and at least one of the driver's and passenger's doors is opened within a preset time window after the vehicle is unlocked, which can be 30 seconds.

[0071] Understandably, in order to accurately predict whether passengers need to get into the vehicle, windows should be opened as early as possible to improve ventilation and cooling, so that passengers can feel a relatively comfortable temperature after opening the car door and entering the vehicle. In some optional embodiments, the preset conditions may only include the following first prediction condition, without determining whether the driver's and passenger's doors are opened: The vehicle control module 302 detects that the car key unlock button has been pressed, and the interior temperature sensor 303 detects that the current interior temperature is higher than a first preset temperature. It's understandable that if an occupant only wants to retrieve items from the trunk, they will most likely only press the trunk unlock button on the rear key or the physical unlock button on the trunk. Therefore, detecting that the car key unlock button has been pressed can accurately predict whether an occupant intends to get into the vehicle.

[0072] In some optional embodiments, the preset conditions may include only the following second pre-judgment condition, without determining whether the driver's and passenger's doors are opened: The vehicle control module 302 detects that the car key unlock button has been pressed, and also determines that the car key is less than a preset distance from the vehicle, while the interior temperature sensor 303 detects that the current interior temperature is greater than a first preset temperature. Understandably, by confirming that the car key is less than a preset distance from the vehicle, it can more accurately predict whether an occupant intends to get in the car, rather than accidentally pressing the unlock button, and it also ensures the safety of valuables inside the vehicle after the windows are opened.

[0073] To ensure safety, in some optional embodiments, if the preset conditions only include the aforementioned first or second pre-judgment condition, without determining whether the driver and passenger doors are opened, the vehicle controller 301, while controlling all windows and the sunroof to be fully open and maintained for a first preset time using the window control unit 304, will continuously monitor whether the driver and passenger doors are opened, and monitor the distance between the car key and the vehicle (i.e., whether the car key is within a preset radius around the vehicle). If, after controlling all windows and the sunroof to be fully open and maintained for the first preset time using the window control unit 304, the driver and passenger doors are still not detected to be opened, or if the car key is detected to have left the preset radius around the vehicle during the process of controlling all windows and the sunroof to be fully open and maintained for the first preset time using the window control unit 304, then the window control unit 304 will control all windows and the sunroof to close, to ensure the safety of valuables inside the vehicle.

[0074] In some optional embodiments, the system further includes a rain sensor 305, and preset conditions also include: Rain sensor 305 detected no rainfall at present.

[0075] In other words, the vehicle controller 301 will only use the window control unit 304 to fully open all windows and sunroof and maintain them for a first preset time when it determines that the following conditions are met: The vehicle control module 302 detects that the vehicle has been unlocked and at least one of the driver's and passenger's doors has been opened, the rain sensor 305 detects that there is currently no rain, and the interior temperature sensor 303 detects that the current interior temperature is greater than a first preset temperature.

[0076] In some optional embodiments, the preset condition may also be that the rain sensor 305 detects no rainfall based on the first prediction condition described above, or that the rain sensor 305 detects no rainfall based on the second prediction condition described above.

[0077] Understandably, if the preset conditions include rainfall-related factors, then the window opening strategy can be flexibly determined based on different rainfall amounts. In some alternative embodiments, when the rain sensor 305 detects that there is no rain, the window control unit 304 controls all windows and the sunroof to be fully opened and maintained for a first preset time.

[0078] In some optional embodiments, when the rain sensor 305 detects that the current rainfall is greater than zero but less than a first preset rainfall, the window control unit 304 controls all windows to open to a preset degree and maintain this opening for a first preset time, while keeping the sunroof closed. The preset opening degree can be one-third, meaning the window is only partially open. It's important to understand that "window" refers to the vehicle's side windows, which are different from the sunroof. In very light rainfall, opening only a small portion of the side windows will not result in a large amount of rainwater entering the vehicle. Therefore, in very light rainfall, the side windows can be opened only slightly, while the sunroof remains closed, thus improving cooling efficiency while ensuring the safety of items inside the vehicle.

[0079] In some alternative embodiments, the system also includes a wind sensor 306 configured to acquire the current ambient wind force and transmit the current ambient wind force to the vehicle controller 301.

[0080] The vehicle controller 301 is configured to determine the opening degree corresponding to the current ambient wind force based on a preset relationship between wind force and opening degree, and to use the window control unit 304 to open all windows and sunroof to the desired opening degree and maintain them for a first preset time. In the preset relationship between wind force and opening degree, wind force and opening degree are negatively correlated.

[0081] It's understandable that when the outside wind is strong, even if the car windows are only partially open, good ventilation and cooling can still be achieved. Moreover, if the outside wind is strong and the car windows are fully open, it may blow away items inside the car, even lighter items, or cause dust to accumulate quickly inside the car. Therefore, setting the relationship between wind force and window opening to a negative correlation can improve the ventilation and cooling effect while ensuring the safety and cleanliness of items inside the car.

[0082] Depending on the angular relationship between the vehicle's orientation and the wind direction of the surrounding environment, the effect of opening windows for ventilation and cooling will vary. Therefore, in some optional embodiments, when the vehicle controller 301 determines that the preset conditions are met, it uses the vehicle navigation system to obtain the current vehicle orientation and uses the vehicle media system to obtain the current weather information, including the current wind direction.

[0083] The vehicle controller 301 calculates the angle between the current vehicle orientation and the current wind direction.

[0084] When the angle is less than the preset angle, it means that the angle between the vehicle and the wind direction is relatively small, and the vehicle is facing the wind head-on or rear-facing. At this time, the window control unit 304 is used to control all windows and sunroof to be fully opened and maintained for the first preset time. By using Bernoulli's principle (the wind force outside the car is greater than inside the car, and the pressure outside the car is less than inside the car at the window), more windows are used to extract the hot air inside the car more quickly.

[0085] When the angle is greater than the preset angle, it means that the angle between the vehicle and the wind direction is relatively large, and the vehicle is facing the wind from the side. At this time, the window control unit 304 is used to control the left front window and the right rear window to be fully opened and maintained for the first preset time, or the window control unit 304 is used to control the right front window and the left rear window to be fully opened and maintained for the first preset time, thereby using fewer windows to accelerate air convection and blow the hot air inside the car out faster.

[0086] Understandably, if occupants are sensitive to wind noise or dislike the feeling of wind blowing directly on their faces, it is also possible to avoid direct wind blowing on their faces while ventilating and cooling. Therefore, in some optional embodiments, when the vehicle controller 301 determines that the preset conditions are met, it uses the body control module 302 to determine which door is being opened. When the driver's door is opened, the window control unit 304 controls the right front window and left rear window to be fully opened and maintained for a first preset time. Alternatively, when the passenger door is opened, the window control unit 304 controls the left front window and right rear window to be fully opened and maintained for a first preset time. This achieves ventilation and cooling while avoiding directly opening the side window closest to the occupant and preventing direct wind blowing on the occupant.

[0087] The above situation corresponds to the case where the vehicle is a left-hand drive vehicle. In some optional embodiments, when the vehicle is a right-hand drive vehicle, the window opening strategy can be completely opposite to that of the left-hand drive vehicle. That is, when the driver's door is opened, the window control unit 304 controls the left front window and the right rear window to be fully opened and kept open for a first preset time. Alternatively, when the passenger door is opened, the window control unit 304 controls the right front window and the left rear window to be fully opened and kept open for a first preset time. This achieves ventilation and cooling while avoiding directly opening the side window closest to the occupant and preventing the wind from blowing directly on the occupant.

[0088] The vehicle controller 301 is also configured to, after controlling all windows and sunroof to be fully opened and maintained for a first preset time using the window control unit 304, control all windows and sunroof to be closed using the window control unit 304, turn on the air conditioner and switch to the internal circulation mode, adjust the air volume to the maximum, and keep the air conditioner compressor running.

[0089] Using the vehicle cooling system provided in this application embodiment, when the vehicle controller 301 determines through the body control module 302 that the vehicle is unlocked and at least one of the driver's or passenger's doors is open, i.e., the vehicle is not armed and the occupants need to get in, and the in-vehicle temperature sensor 303 detects that the current in-vehicle temperature is high, the window control unit 304 directly lowers all the windows completely and opens the sunroof completely, thereby enabling rapid exchange between the hot air inside the vehicle and the outside air, removing the heat from the vehicle and rapidly cooling the interior temperature. This allows users unfamiliar with remote air conditioning control to experience a relatively comfortable temperature after getting in the vehicle, improving the adaptability of the solution and enhancing the user experience.
