Vehicle air conditioning control method, device, electronic equipment and vehicle

[0001] This application claims priority to the patent application number 2023117749558 filed with the China Patent Office on December 21, 2023, entitled “Vehicle Air Conditioning Control Method, Device, Electronic Device and Vehicle,” all contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of vehicle control technology, and in particular to a vehicle air-conditioning control method, device, electronic equipment and vehicle. Background Art

[0003] When a vehicle's speed increases, the air outside the vehicle flows faster and more rapidly, increasing the pressure inside the vehicle. If the air conditioner is in external circulation at this time, more outside air will enter the vehicle than when the vehicle is moving at a slower speed, causing air inside the vehicle to leak to the outside. This will result in energy loss during cooling or heating. Furthermore, excessive outside air entering the vehicle is detrimental to maintaining air cleanliness inside the vehicle.

To reduce air loss from the vehicle, the air conditioning's external circulation damper opening is reduced, thereby reducing energy losses caused by air flowing out of the vehicle. Furthermore, reducing the air conditioning's external circulation damper opening also reduces the amount of air entering the vehicle from outside, preventing dust particles carried by the outside air from affecting the cleanliness of the air inside the vehicle, thereby ensuring excellent air quality inside the vehicle.

[0060] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0061] This application proposes a vehicle air conditioning control method, which is applied to a vehicle controller. Referring to FIG1 , the method includes the following steps:

[0062] Step 102: Obtain the current speed of the vehicle.

[0063] Specifically, as the vehicle's speed changes during driving, the velocity of the air flowing outside the vehicle also changes, which in turn affects the air intake and output volumes of the air conditioner. These changes in air intake and output volumes will have a certain impact on the heating or cooling efficiency of the air conditioner. Therefore, when determining whether to adjust the air conditioner's internal and external circulation modes, it is necessary to consider the current vehicle speed in order to make appropriate adjustments.

[0064] Step 104 : In response to the current vehicle speed exceeding a first preset vehicle speed, adjusting the air conditioner external circulation damper opening of the vehicle according to the current vehicle speed and a preset adjustment rule, wherein, in the preset adjustment rule, the current vehicle speed is negatively correlated with the air conditioner external circulation damper opening.

[0065] Specifically, the first preset vehicle speed represents the minimum speed at which the air conditioning external circulation damper opening needs to be adjusted. When the vehicle speed reaches the first preset speed, the pressure of the external airflow will affect the air flow inside the vehicle. For example, the first preset vehicle speed may be 60 km / h. If the current vehicle speed exceeds the first preset speed, the air conditioning external circulation damper opening needs to be adjusted based on the current vehicle speed to avoid impacting air conditioning efficiency and the interior environment. The preset adjustment rule calibrates the correspondence between vehicle speed and air conditioning external circulation damper opening, with vehicle speed and air conditioning external circulation damper opening corresponding one-to-one. Once the current vehicle speed is determined, a unique air conditioning external circulation damper opening can be determined using the preset adjustment rule. The vehicle speed and air conditioning external circulation damper opening are negatively correlated. That is, the faster the vehicle speed, the smaller the air conditioning external circulation damper opening, and the slower the vehicle speed, the larger the air conditioning external circulation damper opening. When the external circulation damper is open, the faster the vehicle speed, the more outside air enters the vehicle through the air conditioning inlet, and the more air is squeezed out of the vehicle, resulting in increased air loss and energy loss. If the air conditioning is currently in cooling or heating mode, air loss inside the vehicle will increase the air conditioning load and reduce the cooling or heating efficiency of the air conditioning. Therefore, it is necessary to reduce the opening of the external circulation damper to reduce the amount of outside air entering the vehicle, avoid energy loss, and affect the vehicle's range. At the same time, the less outside air enters the vehicle, the fewer dust particles carried by the outside air enter the vehicle, which helps maintain the cleanliness of the vehicle interior.

[0066] Based on steps 102 to 104 above, the vehicle air conditioning control method provided in this embodiment obtains the vehicle's current speed. In response to the current speed exceeding a first preset speed, indicating a need to adjust the air conditioning's external circulation based on the current speed, the air conditioning's external circulation damper opening is adjusted based on the current speed and a preset adjustment rule. The current speed and the air conditioning's external circulation damper opening are negatively correlated. In other words, the faster the current vehicle speed, the more outside air enters the vehicle, and consequently, the more air flows out of the vehicle. To reduce air loss from the vehicle, the air conditioning's external circulation damper opening is reduced, thereby reducing energy losses caused by air flowing out of the vehicle. Furthermore, reducing the air conditioning's external circulation damper opening also reduces the amount of air entering the vehicle from outside, preventing dust particles carried by the outside air from affecting the cleanliness of the air inside the vehicle, thereby ensuring the air quality inside the vehicle.

[0067] It should be noted that, on the basis of adjusting the external circulation damper opening according to the current vehicle speed, in order to avoid destroying the slightly positive pressure state inside the vehicle, it is necessary to maintain a certain external circulation damper opening, which is explained in detail in the following embodiments.

[0068] In some embodiments, the air conditioner external circulation damper opening is greater than a preset minimum opening threshold.

[0069] Specifically, as the vehicle speed increases, the pressure inside the vehicle increases, breaking the micro-positive pressure state inside the vehicle, and dust particles outside the vehicle can easily enter the vehicle, thereby affecting the cleanliness of the air inside the vehicle. Among them, micro-positive pressure is to set the air supply volume entering the vehicle to be about 10% greater than the exhaust volume through the air pressure difference, and the polluted air is discharged outside the vehicle through the purified fresh air, which is conducive to maintaining the cleanliness of the vehicle. In order to maintain the micro-positive pressure state in the vehicle, it is necessary to maintain a certain external circulation damper opening. The preset minimum opening threshold represents the minimum external circulation damper opening that can maintain the micro-positive pressure state. When the external circulation damper opening of the air conditioner is greater than the minimum opening threshold, it can always ensure that the micro-positive pressure state is maintained in the vehicle. Exemplarily, the preset minimum opening threshold can be 1%.

[0070] Based on the above embodiment, the external circulation damper opening can be fixed within a certain vehicle speed range to reduce the frequency of adjusting the air conditioner external circulation damper opening, which is explained below through specific embodiments.

[0071] In some embodiments, in response to the current vehicle speed exceeding a first preset vehicle speed, adjusting the opening of the vehicle's air conditioning external circulation damper according to the current vehicle speed and a preset adjustment rule includes:

[0072] In response to the current vehicle speed exceeding a first preset vehicle speed and being less than a second preset vehicle speed, determining the vehicle air conditioning external circulation damper opening to be a first preset opening;

[0073] In response to the current vehicle speed exceeding the second preset speed and being less than the third preset speed, the air conditioner external circulation damper opening of the vehicle is determined to be the second preset opening; wherein the first preset opening is greater than the second preset opening.

[0074] Specifically, in this embodiment, the first preset vehicle speed is less than the second preset vehicle speed, the second preset vehicle speed is less than the third preset vehicle speed, and the first preset opening is greater than the second preset opening. Within a certain speed range, the impact of vehicle speed on in-vehicle air quality is not significantly different. Therefore, the air conditioner's external circulation damper opening can be fixed within a certain speed range to reduce the frequency of adjusting the air conditioner's external circulation damper opening and the number of vehicle control signal interactions. When the vehicle speed exceeds the first preset speed but is less than the second preset speed, the air conditioner's external circulation damper opening is the first preset opening. When the vehicle speed exceeds the second preset speed but is less than the third preset speed, the air conditioner's external circulation damper opening is the second preset opening. For example, the first preset vehicle speed is 60 km / h, the second preset vehicle speed is 80 km / h, and the third preset vehicle speed is 100 km / h. The first preset opening is 60%, and the second preset opening is 40%. When the vehicle speed range is between 60km / h-80km / h, the outer circulation damper opening is controlled to 60%. When the vehicle speed range is between 80km / h-100km / h, the outer circulation damper opening is controlled to 40%.

[0075] Considering that the faster the vehicle speed, the greater the impact on the air quality inside the vehicle, when adjusting the opening of the air-conditioning external circulation damper according to the vehicle speed, when the vehicle speed is high, the closing speed of the external circulation damper opening can be accelerated to further reduce the impact on the air quality inside the vehicle at higher vehicle speeds. This is explained below through specific embodiments.

[0076] In some embodiments, the preset adjustment rule includes a first inverse ratio and a second inverse ratio; in response to the current vehicle speed exceeding the first preset vehicle speed, adjusting the air conditioner outer circulation damper opening of the vehicle according to the current vehicle speed and the preset adjustment rule includes:

[0077] In response to a current vehicle speed exceeding a first preset speed and being less than a second preset speed, adjusting the opening of the air conditioning external circulation damper of the vehicle according to the current vehicle speed and a first inverse ratio; wherein the first inverse ratio is equal to the ratio of the rate of change of the vehicle speed to the rate of change of the air conditioning external circulation damper opening;

[0078] In response to the current vehicle speed exceeding the second preset speed and being less than the third preset speed, the air conditioning external circulation damper opening of the vehicle is adjusted according to the current vehicle speed and the second inverse ratio; wherein the second inverse ratio is equal to the ratio of the vehicle speed change rate to the air conditioning external circulation damper opening change rate, and the first inverse ratio is greater than the second inverse ratio.

[0079] Specifically, within different speed ranges, the degree of impact of vehicle speed on in-vehicle air quality varies. When the vehicle speed is high, the impact on in-vehicle air quality is greater, while when the vehicle speed is low, the impact on in-vehicle air quality is smaller. In this embodiment, when the vehicle speed is between a first preset speed and a second preset speed, the air conditioning external circulation damper opening is adjusted based on the current vehicle speed and a first inverse ratio. The first inverse ratio is equal to the ratio of the vehicle speed change rate to the air conditioning external circulation damper opening change rate. For example, the first preset speed is 60 km / h and the second preset speed is 80 km / h. If the current vehicle speed increases from the first preset speed to 70 km / h, the vehicle speed change rate is (70 km / h - 60 km / h) / 60 km / h = 0.17. The preset first inverse ratio is 1:1, indicating that the vehicle speed increase rate is the same as the air conditioning external circulation damper opening decrease rate, and the air conditioning external circulation damper opening decrease rate is also 0.17. If the initial air conditioning external circulation damper opening is 80%, the adjusted air conditioning external circulation damper opening is 80% * (1-0.17) = 66%. When the vehicle speed is between the second preset speed and the third preset speed, the air conditioning external circulation damper opening is adjusted based on the current vehicle speed and a second inverse ratio. The second inverse ratio is equal to the ratio of the vehicle speed change rate to the air conditioning external circulation damper opening change rate, and the first inverse ratio is greater than the second inverse ratio. For example, if the second preset speed is 80 km / h and the third preset speed is 100 km / h, if the current vehicle speed increases from the second preset speed to 90 km / h, the vehicle speed change rate is (90 km / h - 80 km / h) / 80 km / h = 0.13. The preset first inverse ratio is 1:2, indicating that the vehicle speed increase rate is 1 / 2 of the air conditioning external circulation damper opening decrease rate. Therefore, the air conditioning external circulation damper opening decrease rate is also 0.26. If the initial opening degree of the air conditioner's external circulation damper is 70%, the adjusted opening degree of the air conditioner's external circulation damper is 70%*(1-0.26)=52%.

[0080] Through the vehicle air-conditioning control method in this embodiment, different inverse ratios are formulated in different vehicle speed ranges, that is, different ratios of the air-conditioning external circulation damper opening rate to the vehicle speed change rate are formulated. When the vehicle speed is high, the closing rate of the air-conditioning external circulation damper opening can be accelerated, further reducing the impact on the air quality in the vehicle at higher vehicle speeds.

[0081] Furthermore, when the vehicle speed is low, the air conditioning external circulation damper opening can be set to a fixed value to ensure ventilation needs within the vehicle, maintain a certain ventilation rate, and maintain the air quality within the vehicle. The specific method includes: in response to the current vehicle speed not exceeding a first preset speed, determining the vehicle's air conditioning external circulation damper opening to a third preset opening. The third preset opening is greater than the first preset opening and the second preset opening. For example, the first preset speed is 60 km / h and the third preset opening is 80%. When the vehicle speed is less than the first preset speed, changes in vehicle speed have little impact on the air quality within the vehicle. In this case, the air conditioning external circulation damper opening can be set to a larger value to ensure the ventilation rate within the vehicle, maintain the air quality within the vehicle, and improve driving comfort. In the aforementioned embodiment, the premise for adjusting the air conditioning external circulation damper opening based on vehicle speed is that the vehicle's external circulation mode is already enabled and the external circulation damper opening is adjustable. In other words, under certain operating conditions, the vehicle must first enable external circulation mode and then further adjust the external circulation damper opening based on the current vehicle speed to reduce vehicle energy consumption and improve vehicle range. The following uses several embodiments to illustrate the operating conditions when the external circulation mode is turned on, specifically including defogging conditions, conditions with high water vapor content, conditions with external pollutants, and congestion conditions.

[0082] In some embodiments, before obtaining the current speed of the vehicle, the method further includes:

[0083] Obtain the humidity inside the vehicle's front windshield, the surface temperature of the front windshield, and the temperature inside the vehicle;

[0084] The dew point is calculated based on the humidity inside the front windshield and the temperature inside the vehicle;

[0085] Determine the fogging risk level based on the front windshield surface temperature and dew point;

[0086] In response to the fogging risk level exceeding a preset level threshold, the external circulation damper opening of the air conditioner is adjusted based on the fogging risk level, wherein the external circulation damper opening is positively correlated with the fogging risk level.

[0087] This embodiment is aimed at the defogging condition. First, the vehicle information is used to determine whether the front windshield of the vehicle is at risk of fogging. The humidity inside the front windshield is obtained by the humidity sensor, and the surface temperature of the front windshield and the temperature inside the vehicle are obtained by the temperature sensor. The dew point is calculated based on the humidity inside the front windshield and the temperature inside the vehicle using equations (1) and (2).

[0088] Among them, T dRepresents the dew point, T represents the temperature inside the vehicle, RH represents the humidity inside the front windshield, and a and b are constants. The fogging risk level is determined based on the front windshield surface temperature and dew point. When the current windshield surface temperature is greater than the dew point temperature, the fogging risk level is no risk. When the current windshield surface temperature is equal to the dew point, the fogging risk level is low risk. When the current windshield surface temperature is less than the dew point, the fogging risk level is high risk. The preset level threshold can be low risk. In response to the fogging risk level exceeding the low risk, the air conditioner's external circulation damper opening is adjusted according to the fogging risk level to avoid fogging of the vehicle's front windshield, which affects driving safety. Exemplarily, when the fogging risk level is low risk, the external circulation damper opening is increased by a first preset opening amount based on the current opening, for example, by 30%. When the fogging risk level is high risk, the external circulation damper is fully opened and set to full external circulation.

[0089] It should be noted that, in addition to the three aforementioned fogging risk levels, multiple risk levels can be set between low and high risk using a differential method, such as a medium risk level. When the fogging risk level reaches medium, the external air circulation damper opening is increased by a second predetermined amount, for example, by 60%, based on the current opening. This embodiment of the air conditioning control method effectively prevents windshield fogging, obstructing the driver's vision and ensuring driving safety.

[0090] In some embodiments, before obtaining the current speed of the vehicle, the method further includes:

[0091] Get the current water vapor content outside the vehicle;

[0092] Adjust the vehicle's air conditioning internal and external circulation modes according to the current water vapor content.

[0093] This embodiment targets rainy or humid conditions. It adjusts the internal and external air conditioning circulation modes based on the current water vapor content. To prevent water from entering the vehicle, the external circulation can be appropriately activated to ensure good ventilation and excellent air quality inside the vehicle. If the current water vapor content is high and activating the external circulation could easily cause water to enter the vehicle, the external circulation can be disabled to prioritize vehicle safety.

[0094] Furthermore, the vehicle's air conditioning internal and external circulation modes are adjusted according to the current water vapor content, including:

[0095] The target external circulation damper opening of the air conditioner is determined based on the current water vapor content and a first preset adjustment relationship, and the external circulation damper opening of the air conditioner of the vehicle is adjusted based on the target external circulation damper opening, wherein in the first preset adjustment relationship, the current water vapor content is negatively correlated with the target external circulation damper opening.

[0096] Specifically, the current water vapor content can be determined using a water vapor measurement sensor. A water vapor measurement sensor installed in the vehicle can detect the amount of water vapor. When the current water vapor content exceeds a minimum limit, it can be determined that the vehicle is currently experiencing rainy conditions or high humidity. A first preset adjustment relationship pre-calibrates the correspondence between water vapor content and external circulation damper opening: the greater the water vapor content, the smaller the external circulation damper opening. When the water vapor content is high, the external circulation damper opening is reduced, effectively preventing external water vapor from entering the vehicle through the external circulation channel. When the water vapor content is low, while preventing external water vapor from entering the vehicle, the external circulation damper opening is appropriately increased to allow more external air to enter the vehicle, improving ventilation efficiency and enhancing the air quality inside the vehicle. Once the current water vapor content is determined, a target external circulation damper opening corresponding to the current water vapor content can be determined based on the first preset adjustment relationship. The air conditioner's external circulation damper opening is then adjusted from the current opening to the target opening, enabling flexible adjustment of the air conditioner's external circulation mode. This embodiment prevents excessive moisture from entering the vehicle while ensuring continuous ventilation of the vehicle, thereby ensuring the quality of the air inside the vehicle and preventing damage to the performance of vehicle components caused by moisture entering the vehicle.

[0097] In some embodiments, before obtaining the current speed of the vehicle, the method further includes:

[0098] Obtain the concentration of pollutants outside the vehicle;

[0099] In response to the concentration of pollutants outside the vehicle being less than or equal to a first preset concentration threshold, switching the internal and external circulation mode of the air conditioner to a full external circulation mode;

[0100] In response to the concentration of pollutants outside the vehicle being greater than a first preset concentration threshold and less than a second preset concentration threshold, the outer circulation damper opening and the inner circulation damper opening of the air conditioner are adjusted according to the concentration of pollutants outside the vehicle and a preset concentration adjustment rule, wherein, in the preset concentration adjustment rule, the concentration of pollutants outside the vehicle is negatively correlated with the outer circulation damper opening, and the concentration of pollutants outside the vehicle is positively correlated with the inner circulation damper opening.

[0101] This embodiment targets conditions involving external pollutants. When pollutants are present at a certain concentration outside the vehicle, they will have a certain impact on the air quality inside the vehicle and may harm the driver's health. However, when the concentration of pollutants outside the vehicle is low, external circulation can be appropriately activated to ensure air circulation inside the vehicle. External pollutants can include harmful substances such as sulfur oxides and nitrogen oxides. The concentration of pollutants outside the vehicle can be detected by sensors installed outside the vehicle, for example, a sulfur oxide sensor for detecting sulfur oxide concentrations, or a nitrogen oxide sensor for detecting nitrogen oxide concentrations. In response to the external pollutant concentration being less than or equal to a first preset concentration threshold, the air conditioner's internal and external circulation mode is switched to full external circulation. For example, the first preset concentration threshold may be 200 PPM. When the external pollutant concentration is less than or equal to 200 PPM, there is no impact on human health, and full external circulation can be activated to ensure adequate ventilation inside the vehicle. In response to the external pollutant concentration being less than or equal to a second preset concentration threshold, the air conditioner's internal and external circulation mode is switched to full internal circulation. This indicates that the external pollutant concentration is too high and could harm human health. For example, the second preset concentration threshold may be 500 PPM. In response to the concentration of pollutants outside the vehicle being between a first preset concentration threshold and a second preset concentration threshold, the outer circulation damper opening and the inner circulation damper opening can be proportionally adjusted according to a preset concentration adjustment rule. The preset concentration adjustment rule calibrates the correspondence between the concentration of pollutants outside the vehicle and the outer circulation damper opening and the inner circulation damper opening. The higher the concentration of pollutants outside the vehicle, the smaller the outer circulation damper opening is to prevent pollutants outside the vehicle from entering the vehicle and affecting the air quality inside the vehicle. At the same time, the larger the opening of the inner circulation damper is to ensure air flow inside the vehicle. The higher the concentration of pollutants outside the vehicle, the larger the opening of the outer circulation damper is to ensure the ventilation rate requirement inside the vehicle. At the same time, the smaller the opening of the inner circulation damper is, the air flow inside the vehicle is mainly guaranteed by the outer circulation. Through the air conditioning control method of this embodiment, it is possible to ensure the air quality inside the vehicle while meeting the ventilation requirements inside the vehicle and improving driving comfort.

[0102] In some embodiments, the vehicle air conditioning control method further includes:

[0103] In response to the current vehicle speed exceeding a second preset speed, or there being no other vehicles within a preset range in front of the vehicle, the air conditioning's internal and external circulation mode is switched to full external circulation, wherein the second preset speed is less than the first preset speed.

[0104] This embodiment targets congested conditions. The distribution of vehicles within a preset range ahead of the vehicle can be determined based on images captured by a camera positioned ahead of the vehicle. When congestion is severe, a large amount of exhaust gas may be present around the vehicle, resulting in poor air quality. External circulation may need to be disabled to prevent outside air from entering the vehicle and affecting the air quality. When congestion is less severe, external circulation may be appropriately enabled to meet vehicle ventilation needs. For example, the second preset speed may be 20 km / h, and the preset range may be a circle with a radius of 10 meters centered on the vehicle. When the current vehicle speed exceeds the second preset speed and there are no other vehicles within the preset range, it can be assumed that there is no traffic jam or that the traffic jam is not severe. The air conditioning system's internal and external circulation mode can be switched to full external circulation, effectively disabling the internal circulation and adjusting the external circulation damper to its maximum value to ventilate the vehicle at the fastest rate. For example, when the current vehicle speed does not exceed the second preset speed and there are other vehicles within the preset range ahead of the vehicle, it can be assumed that the traffic jam is severe and external circulation may need to be disabled to prevent outside air from entering the vehicle. When the current vehicle speed is between a first preset speed and a second preset speed, the external circulation mode can be proportionally adjusted. The corresponding external circulation damper opening is determined based on the current vehicle speed. The vehicle speed and the external circulation damper opening are positively correlated. When the vehicle speed is below the second preset speed, the faster the vehicle speed, the larger the external circulation damper opening, thereby achieving rapid ventilation and ensuring good in-vehicle air quality. The vehicle air conditioning control method provided in this embodiment can appropriately adjust the external circulation damper opening in congested conditions, appropriately increasing the in-vehicle air circulation rate while ensuring in-vehicle air quality, achieving rapid ventilation and providing a good driving experience for the user.

[0105] The preceding embodiments describe various operating conditions for activating the external circulation system. After activation, the air conditioning system's internal and external circulation modes can be further adjusted based on vehicle speed to reduce vehicle energy loss and increase range. To further enhance driving comfort, the air conditioning system can be remotely activated before use, allowing the driver to adjust the internal and external circulation modes based on their actual needs. The specific adjustment methods are described in the following embodiments.

[0106] In some embodiments, the vehicle air conditioning control method further includes:

[0107] Get the current control mode of the air conditioner;

[0108] In response to the current control mode being the heating mode, adjusting the internal and external circulation mode of the air conditioner to a full internal circulation mode;

[0109] In response to the current control mode being the ventilation mode, adjusting the internal and external circulation mode of the air conditioner to full external circulation;

[0110] In response to the current control mode being the cooling mode and the vehicle interior temperature being greater than the vehicle exterior temperature, adjusting the air conditioning's internal and external circulation mode to a full external circulation mode;

[0111] In response to the current control mode being the cooling mode and the vehicle interior temperature being less than or equal to the vehicle exterior temperature, the interior-exterior circulation mode of the air conditioner is adjusted to a full interior circulation mode.

[0112] Specifically, the driver can remotely turn on the air conditioning or schedule it before using the vehicle to ensure that the interior temperature or air quality meets the driver's requirements. If the driver remotely selects heating mode, the air conditioning's external circulation is turned off and full internal circulation is activated to quickly meet the desired interior temperature, while also considering energy conservation. This prevents heat loss caused by the loss of air from the interior to the outside during the heating process. If the driver remotely selects ventilation mode, the air conditioning's internal circulation is turned off and full external circulation is activated to quickly ventilate the interior air, accelerating the exchange of air between the interior and exterior. If the driver remotely selects cooling mode, the interior and exterior temperatures are also considered. If the interior temperature is higher than the exterior temperature, the air conditioning's internal and external circulation modes are adjusted to full external circulation, allowing a larger amount of cool air from outside to enter the vehicle, accelerating cooling efficiency, saving energy, and reducing air conditioning load. If the temperature inside the vehicle is lower than the outside temperature, the air conditioner's internal and external circulation mode is adjusted to full internal circulation mode to prevent air from leaking outside and causing cold air loss. Enabling full internal circulation improves the cooling efficiency of the vehicle's air, quickly reaching the driver's desired temperature. This embodiment of the vehicle air conditioning control method can quickly meet the driver's desired temperature and air quality while ensuring energy conservation, thereby improving driving comfort.

[0113] Furthermore, during vehicle travel, in order to further reduce the load of the air conditioner, the internal and external circulation modes of the air conditioner may be finely controlled, which will be described in detail in the following embodiments.

[0114] In some embodiments, the vehicle air conditioning control method further includes:

[0115] Get the current control mode of the air conditioner;

[0116] In response to the current control mode being the heating mode and the current internal and external circulation mode being the external circulation mode, the internal circulation damper opening of the air conditioner is adjusted to the maximum value; in response to the current control mode being the heating mode and the current internal and external circulation mode being the automatic mode, the internal and external circulation mode of the air conditioner is adjusted to the full internal circulation;

[0117] In response to the current control mode being the ventilation mode and the current internal and external circulation mode being the external circulation mode, the internal and external circulation mode of the air conditioner is adjusted to the full external circulation mode; in response to the current control mode being the ventilation mode and the current internal and external circulation mode being the automatic mode, the internal and external circulation mode of the air conditioner is adjusted to the full internal circulation mode;

[0118] In response to the current control mode being cooling mode and the temperature inside the vehicle being greater than the temperature outside the vehicle, the internal and external circulation modes of the air conditioner are adjusted to full external circulation mode; in response to the current control mode being cooling mode and the temperature inside the vehicle being less than or equal to the temperature outside the vehicle, the internal and external circulation modes of the air conditioner are adjusted to full internal circulation mode.

[0119] Specifically, to further reduce energy consumption while the vehicle is in motion, the air conditioning's internal and external circulation modes are finely controlled in each control mode. If the air conditioning's current control mode is heating, and the internal and external circulation mode set by the driver is external, then in the current external mode, the internal circulation damper opening is adjusted to the maximum value to reduce the loss of hot air in the vehicle, allowing the vehicle temperature to quickly rise to the driver's desired temperature. If the air conditioning's current control mode is heating, and the internal and external circulation mode set by the driver is automatic, then the internal and external circulation mode is adjusted to full internal circulation to minimize the loss of hot air in the vehicle.

[0120] If the air conditioner's current control mode is ventilation mode, and the current internal and external circulation mode is set to external circulation mode, the air conditioner's internal and external circulation mode will be adjusted to full external circulation mode to complete the vehicle's ventilation at the fastest rate and improve the air quality inside the vehicle. If the air conditioner's current control mode is ventilation mode, and the current internal and external circulation mode is set to automatic mode, the air conditioner's internal and external circulation mode will be adjusted to full internal circulation mode, achieving air circulation inside the vehicle through internal circulation. Full internal circulation is more energy-efficient than full external circulation, effectively reducing vehicle energy consumption.

[0121] If the current control mode of the air conditioner is cooling mode, the temperature inside the car and outside the car also need to be considered. If the temperature inside the car is higher than the temperature outside the car, the internal and external circulation modes of the air conditioner are adjusted to full external circulation, allowing a large amount of cold air outside the car to enter the car, accelerating the cooling efficiency of the air inside the car, saving energy, and reducing the air conditioning load. If the temperature inside the car is lower than the temperature outside the car, the internal and external circulation modes of the air conditioner are adjusted to full internal circulation to prevent the air inside the car from leaking to the outside of the car, causing cold air loss. Turning on full internal circulation can improve the cooling efficiency of the air inside the car and reach the driver's required temperature as soon as possible. The vehicle air conditioning control method of this embodiment further reduces vehicle energy consumption and improves driving comfort by finely adjusting the internal and external circulation modes of the air conditioner to quickly meet the driver's requirements for temperature and air quality inside the car.

[0122] With the development of vehicle electronic technology, vehicle control functions are becoming increasingly complex, and different vehicle operating conditions correspond to different control logics. For air-conditioning control systems, the simultaneous existence of multiple control logics may cause the air-conditioning system to fail to operate normally. The execution of inappropriate control logic may pose a driving safety hazard and cause physical and mental damage to the driver. For example, the current vehicle's air-conditioning internal and external circulation mode is internal circulation and has lasted for a period of time. It is necessary to regularly turn on the external circulation for ventilation. However, if the concentration of air pollutants outside the vehicle is high at this time, it is not appropriate to turn on the external circulation for ventilation, resulting in a control logic conflict problem. In view of this, the present application also proposes a vehicle air-conditioning control method to solve the problem of control logic conflicts in the air-conditioning control system, and to formulate a more reasonable priority order by refining the instruction category of the air-conditioning adjustment instruction to ensure driving safety and comfort.

[0123] The present application provides a vehicle air conditioning control method, referring to FIG2 , comprising the following steps:

[0124] Step 202: Generate at least one air conditioning adjustment instruction, wherein the instruction category of the air conditioning adjustment instruction includes at least one of a safety category, an environmental category, and an energy-saving category.

[0125] Specifically, air conditioning adjustment commands are generated based on the vehicle's current driving information and surrounding environment information. The vehicle's current operating conditions may include multiple different operating conditions, such as defogging, the presence of air pollutants outside the vehicle, and energy-saving conditions. Different air conditioning adjustment commands are generated for different operating conditions, and different air conditioning adjustment commands correspond to different air conditioning control logic. In this embodiment, air conditioning adjustment commands are divided into three command categories: safety, environment, and energy-saving. Safety commands are those that can affect driving safety, such as defogging commands, which can eliminate fog on the vehicle's windshield, preventing obstruction to the driver's vision and posing a driving safety hazard. Environment commands are those that can affect the in-vehicle environment, such as pollutant adjustment commands, ventilation commands, and window washing commands. Air conditioning adjustment commands in the environment category can control the air conditioning's internal and external circulation systems to ensure excellent in-vehicle air quality, providing a comfortable and healthy driving environment for the user. The energy-saving category is a category of instructions that can affect vehicle energy consumption. For example, energy-saving instructions can be used to adjust the internal and external circulation modes of the air conditioner. On the basis of meeting the user's demand for air conditioning use, the operating mode and operating efficiency of the air conditioner can be further optimized, thereby reducing vehicle energy consumption and improving vehicle endurance.

[0126] By finely dividing the instruction categories, it is helpful to formulate a priority order that can adapt to different vehicle operating conditions, so as to meet users' needs for air conditioning under complex operating conditions.

[0127] Step 204 : Determine a target adjustment instruction from at least one air conditioning adjustment instruction according to a preset priority order corresponding to the instruction category.

[0128] Specifically, the priority corresponding to each instruction category is marked in the preset priority order, and different instruction categories have different priorities. Exemplarily, the instruction categories include safety category, environment category and energy-saving category, and the preset priority order includes three levels of priority, which can be level one priority, level two priority and level three priority respectively. Different instruction categories are assigned different priority levels according to the degree of influence of the instruction category on driving safety and comfort, forming a preset priority order. The preset priority order can be set according to different vehicle models and different vehicle usage requirements. After determining the preset priority order, the air-conditioning adjustment instruction corresponding to the highest priority can be determined from at least one air-conditioning adjustment instruction as the target adjustment instruction. The target adjustment instruction can reflect the most important vehicle usage requirement of the current vehicle, and the priorities of other air-conditioning adjustment instructions are lower than the priority of the target adjustment instruction. According to the preset priority order, the instruction with the highest priority can be accurately determined from at least one air-conditioning adjustment instruction, avoiding the problem of control logic conflict caused by the simultaneous execution of multiple instructions.

[0129] Step 206: Adjust the internal and external circulation modes of the air conditioner according to the target adjustment instruction.

[0130] Specifically, after determining the target adjustment instruction, the air conditioner's internal and external circulation modes are adjusted according to the target adjustment instruction to meet the user's driving needs. For example, if the target adjustment instruction indicates that full internal circulation is required, then based on the current air conditioner internal and external circulation mode, the external circulation is disabled and the internal circulation damper opening is adjusted to the maximum value; if the target adjustment instruction indicates that full external circulation is required, then based on the current air conditioner internal and external circulation mode, the internal circulation is disabled and the external circulation damper opening is adjusted to the maximum value; if the target adjustment instruction indicates that proportional internal and external circulation is required, then the current internal and external circulation damper opening is adjusted according to the target internal circulation damper opening and the target external circulation damper opening contained in the target adjustment instruction.

[0131] Based on steps 202 to 206 above, this embodiment provides a vehicle air conditioning control method, comprising generating at least one air conditioning adjustment command. The at least one air conditioning adjustment command is generated based on the current vehicle condition and environmental information, indicating that the current operating condition satisfies multiple vehicle operating conditions, and different adjustment commands correspond to different vehicle operating conditions. The air conditioning adjustment command includes at least one of a safety category, an environmental category, and an energy-saving category. This fine-grained classification of the command categories facilitates the rational prioritization of commands. Executing the air conditioning adjustment commands in this order of priority helps ensure driving safety and comfort. When multiple adjustment commands for the air conditioning control system are simultaneously issued, a target adjustment command is determined from the at least one air conditioning adjustment command based on a preset priority order. Specifically, the target adjustment command is the air conditioning adjustment command with the highest current priority, which satisfies the user's most important driving needs. This avoids control logic conflicts when multiple adjustment commands are executed simultaneously, which could result in improper operation of the air conditioning system. After determining the target adjustment command, the internal and external circulation modes of the air conditioning system are adjusted based on the target adjustment command to ensure vehicle driving safety and comfort, thereby enhancing the user's driving experience.

[0132] At least one air conditioning adjustment instruction may include air conditioning adjustment instructions of the same instruction category, for example, air conditioning adjustment instructions of multiple environmental categories. In this case, it is necessary to further determine the priority corresponding to the air conditioning adjustment instructions of each environmental category to determine the final target adjustment instruction. The specific method is described in detail through the following embodiments.

[0133] In some embodiments, determining a target adjustment instruction from at least one air conditioning adjustment instruction according to a preset priority order corresponding to the instruction category includes:

[0134] Determining the category priority corresponding to each air conditioning adjustment instruction according to a category priority order in a preset priority order, wherein the instruction categories in the category priority order are safety category, environment category, and energy-saving category from high to low;

[0135] In response to the presence of a plurality of air conditioning adjustment instructions having the same category priority, determining the instruction priority of each of the plurality of air conditioning adjustment instructions having the same category priority according to an instruction priority order in a preset priority order;

[0136] The air conditioning adjustment instruction with the highest priority among all the air conditioning adjustment instructions is used as the target adjustment instruction.

[0137] Specifically, the preset priority order includes a category priority order and an instruction priority order. The category priority order specifies the priorities corresponding to different instruction categories, while the instruction priority order specifies the priorities corresponding to different instructions within the same instruction category. After generating at least one air conditioning control instruction, the category priority corresponding to each air conditioning control instruction must first be determined. If there are multiple air conditioning control instructions with the same category priority, the instruction priority for each air conditioning control instruction is then determined from the multiple air conditioning control instructions corresponding to the same category priority. Finally, the air conditioning control instruction with the highest category priority and the air conditioning control instruction with the highest instruction priority among the at least one air conditioning control instruction is selected as the target control instruction. The instruction categories specified in the category priority order are, from highest to lowest, safety category, environmental category, and energy-saving category. Specifically, safety category has a first-level priority, environmental category has a second-level priority, and energy-saving category has a third-level priority. If there are air conditioning control instructions with the same category priority, the final target priority is determined based on the instruction priorities corresponding to the corresponding instruction categories. For example, if the instruction categories of at least one air conditioning control instruction include safety category, environmental category, and energy-saving category, the air conditioning control instruction corresponding to the safety category is selected as the candidate control instruction. If there is only one candidate adjustment instruction, then the candidate adjustment instruction is the target adjustment instruction. If there are multiple candidate adjustment instructions, the instruction priority of each candidate adjustment instruction is determined, and the instruction with the highest instruction priority is used as the target adjustment instruction. In other words, if the target adjustment instruction can be directly determined by the category priority, there is no need to determine the instruction priority. If the target adjustment instruction cannot be directly determined by the category priority, it is necessary to confirm the target adjustment instruction by the instruction priority. Through the target adjustment instruction determination method of this embodiment, the target adjustment instruction can be quickly determined from at least one air-conditioning adjustment instruction, and the target adjustment instruction can be executed in a timely manner through the air-conditioning control system, quickly responding to the user's air-conditioning usage needs during driving, and improving the user's driving experience.

[0138] Among the instruction categories, there are many types of air conditioning adjustment instructions corresponding to the environmental category. Establishing the instruction priority order corresponding to the environmental category will help to reasonably control the air conditioning in a complex environment to ensure the air quality in the car and the physical and mental health of the user. This will be explained in detail through examples below.

[0139] In some embodiments, in response to the presence of multiple air conditioning adjustment instructions having the same category priority, determining the instruction priority of each of the multiple air conditioning adjustment instructions having the same category priority according to the instruction priority order in a preset priority order includes:

[0140] In response to the fact that the instruction categories corresponding to multiple air-conditioning adjustment instructions are all environmental categories, the instruction priority of each air-conditioning adjustment instruction in the multiple air-conditioning adjustment instructions is determined according to the instruction priority order corresponding to the environmental categories, wherein the instructions in the instruction priority order corresponding to the environmental categories are, from high to low, the pollutant full internal circulation instruction, the car and window washing full internal circulation instruction, and the ventilation external circulation instruction.

[0141] Specifically, if the instruction categories of multiple air conditioning adjustment instructions are all environmental categories, the instruction priority corresponding to each air conditioning adjustment instruction needs to be determined according to the pre-calibrated instruction priority order. Instructions of the environmental category include full internal circulation instructions for pollutants, full internal circulation instructions for car and window washing, and external circulation instructions for ventilation. The corresponding instruction priorities are A, B, and C, respectively. Class A has the highest priority, Class B has the second highest priority, and Class C has the lowest priority. The full internal circulation instruction for pollutants means that when the concentration of air pollutants outside the vehicle reaches a certain concentration, the external circulation needs to be turned off and the full internal circulation needs to be turned on to prevent pollutants from entering the vehicle through the external circulation channel and affecting the air quality inside the vehicle. Air pollutants outside the vehicle may cause damage to the physical and mental health of users in the vehicle. Therefore, when the air pollutants outside the vehicle exceed a certain concentration, the external circulation needs to be turned off immediately. The highest priority of the full internal circulation instruction for pollutants is Class A. The full internal circulation instruction for car and window washing means that the external circulation needs to be turned off when car washing or window washing conditions occur. During car washing, due to the large amount of water, turning on the external circulation can easily cause a large amount of water vapor to enter the car through the external circulation channel, causing damage to the components inside the car, and thus affecting the service life of the vehicle. Therefore, it is necessary to turn off the external circulation and turn on the full internal circulation. During window washing, since the glass water used for window washing usually has a pungent chemical smell, in order to prevent external odors from entering the car, it is necessary to turn off the external circulation and turn on the internal circulation. The priority of the full internal circulation command for car washing and window washing is Class B. The ventilation external circulation command means that after the full internal circulation in the car is turned on and maintained for a certain period of time, in order to maintain the air quality in the car, it is necessary to regularly turn on the external circulation for ventilation. At the same time, the fresh air entering from the outside can keep the driver clear-headed and improve driving safety. The priority of the ventilation external circulation command is Class C.

[0142] For example, if at least one air conditioning adjustment instruction includes an environmental category and an energy-saving category, since the priority of the environmental category is a second-level priority and the priority of the energy-saving category is a third-level priority, the air conditioning adjustment instruction corresponding to the environmental category is used as a candidate adjustment instruction. If there are multiple candidate adjustment instructions, the instruction priority of each candidate adjustment instruction is determined. If the candidate adjustment instructions are a pollutant full internal circulation instruction and a car and window washing full internal circulation instruction, since the priority of the pollutant full internal circulation instruction is Class A and the priority of the car and window washing full internal circulation instruction is Class B, the pollutant full internal circulation instruction is used as the final target adjustment instruction. This embodiment can formulate reasonable instruction priorities for complex driving environments, and quickly determine the target adjustment instruction based on the instruction priority, and promptly execute the target adjustment instruction through the air conditioning control system, quickly respond to the user's air conditioning usage needs during driving, and enhance the user's driving experience.

[0143] The above embodiments describe how to determine a target adjustment instruction after generating at least one air conditioning adjustment instruction. The following describes how to generate at least one air conditioning adjustment instruction through an embodiment.

[0144] In some embodiments, generating at least one air conditioning adjustment instruction includes:

[0145] Obtain vehicle information and / or environmental information;

[0146] At least one air-conditioning adjustment instruction is generated according to the vehicle information and / or the environmental information.

[0147] Specifically, vehicle information refers to information related to vehicle operation. This information can be obtained from various on-board controllers or processors, including, for example, vehicle speed and operating conditions. Environmental information includes interior and exterior temperature, humidity, and pollutant concentrations, and can be obtained through various on-board sensors. These two information represent the vehicle's current driving and environmental conditions. If these conditions meet the corresponding preset operating conditions, corresponding air conditioning adjustment instructions are generated.

[0148] The following describes a specific method for generating an air conditioning adjustment instruction through several embodiments.

[0149] In some embodiments, the vehicle information includes humidity inside the vehicle's front windshield and the surface temperature of the front windshield, the environmental information includes the temperature inside the vehicle, and the air conditioning adjustment instruction includes an instruction to turn on a defogger external circulation;

[0150] Generating at least one air conditioning adjustment instruction according to vehicle information and / or environmental information includes:

[0151] The dew point is calculated based on the humidity inside the front windshield and the temperature inside the vehicle;

[0152] Determine the fogging risk level based on the front windshield surface temperature and dew point;

[0153] In response to the fogging risk level exceeding the preset level threshold, a demisting external circulation start instruction is generated, wherein the external circulation damper opening in the demisting external circulation start instruction is positively correlated with the fogging risk level, and the instruction category of the demisting external circulation start instruction is a safety category.

[0154] In some embodiments, the environmental information includes a concentration of pollutants outside the vehicle, and the air conditioning adjustment instruction includes an instruction for full internal circulation of pollutants; determining at least one air conditioning adjustment instruction based on the vehicle information and / or the environmental information includes:

[0155] In response to the concentration of pollutants outside the vehicle exceeding a preset concentration threshold, a pollutant full internal circulation instruction is generated, wherein the pollutant full internal circulation instruction is used to switch the current internal and external circulation mode of the air conditioner to a full internal circulation mode, and the instruction category of the pollutant full internal circulation instruction is an environmental category.

[0156] In some embodiments, the vehicle information includes the current operating condition, and the air conditioning adjustment instruction includes a full internal circulation instruction for washing the car and windows; determining at least one air conditioning adjustment instruction based on the vehicle information and / or environmental information includes:

[0157] In response to the current operating condition being a car washing condition or a window washing condition, a car washing and window washing full internal circulation instruction is generated, wherein the car washing and window washing full internal circulation instruction is used to switch the current internal and external circulation mode of the air conditioner to a full internal circulation mode, and the instruction category of the car washing and window washing full internal circulation instruction is an environmental category.

[0158] This embodiment is directed to a full internal circulation instruction for car washing and window washing. If the current operating condition is a car washing condition or a window washing condition, a full internal circulation instruction for car washing and window washing is generated. The window washing condition refers to spraying glass water on the outside of the front windshield to clean the front windshield. Glass water is usually added with some chemical reagents that are harmful to the human body. Chemical reagents usually have a certain pungent odor. In order to prevent the odor of chemical reagents from entering the car during the window washing condition and affecting the health of the people in the car, the opening of the external circulation damper is adjusted to zero, that is, the external circulation is closed, and the odor outside the car is prevented from entering the car through the external circulation channel, ensuring that the air quality inside the car is not affected and improving the driver's driving experience.

[0159] When the external circulation damper of the air conditioner is closed in the window washing condition, the pungent smell of the chemical reagent can be isolated. When the external smell dissipates, the external circulation damper can be opened to continue to maintain the ventilation needs in the vehicle. Therefore, in some embodiments, the vehicle air conditioning control method further includes: in response to the duration for which the external circulation damper opening is continuously zero for more than a preset duration, restoring the external circulation damper opening to a target opening. Exemplarily, the preset duration can be 1 minute. When the external circulation damper is completely closed for more than 1 minute, reopen the external circulation damper and restore the external circulation damper opening to the target opening. The target opening is the opening after adjusting the external circulation damper opening according to the current rainfall.

[0160] When the current operating condition is detected as a car wash, in addition to closing the windows, the external circulation damper must also be closed to prevent water from entering the vehicle through the external circulation channel. The air conditioner's external circulation damper opening is reduced from its current value to zero, effectively shutting off the external circulation and preventing large amounts of water from entering the vehicle and damaging internal components. This embodiment is suitable for use when the vehicle is powered on, such as when the driver is performing an automatic car wash while inside the vehicle. Closing the doors and windows while shutting off the external circulation effectively prevents water from entering the vehicle.

[0161] In some embodiments, the vehicle information includes the air conditioner outlet temperature, and the air conditioner adjustment instruction includes a ventilation external circulation instruction; determining at least one air conditioner adjustment instruction based on the vehicle information and / or environmental information includes:

[0162] In response to the fact that the current internal and external circulation mode of the air conditioner is a full internal circulation mode and the duration exceeds a first preset duration threshold, a ventilation external circulation instruction is generated, wherein the ventilation external circulation instruction is used to switch the current internal and external circulation mode from a full internal circulation mode to a full external circulation mode, and the instruction category of the ventilation external circulation instruction is an environmental category.

[0163] Specifically, when the current internal and external circulation mode of the air conditioner is switched to full internal circulation, the timer is started and starts timing. When the duration exceeds the first predetermined duration, it is switched to full external circulation, ventilation is started, and the timer is reset and restarted. If the external circulation duration exceeds the second predetermined duration, it is switched to full internal circulation, and the timer is reset and restarted. If the external circulation duration does not exceed the second predetermined duration, and the temperature change at the air conditioner outlet exceeds the preset temperature difference, the current internal and external circulation mode of the air conditioner is switched to full internal circulation, and the timer is reset and restarted. The fact that the temperature change at the air conditioner outlet exceeds the preset temperature difference indicates that the temperature difference between the inside and outside of the car is large. In order to prevent energy loss caused by air loss in the car, the current internal and external circulation mode of the air conditioner is switched to full internal circulation in time to avoid further air loss in the car. For example, the first predetermined duration is 15 minutes, the second predetermined duration is 15 seconds, and the preset temperature difference is 6°C. The air conditioning control method of this embodiment can ensure that the air quality in the car remains good. Turning on the external circulation for a certain period of time can increase the oxygen content in the car, keep the driver clear-headed, and improve driving safety.

[0164] In some embodiments, the vehicle information includes a current air conditioning internal and external circulation mode and a current air conditioning control mode, the environmental information includes an interior temperature and an exterior temperature, and the air conditioning adjustment instruction includes an energy-saving full interior circulation activation instruction; determining at least one air conditioning adjustment instruction based on the vehicle information and / or the environmental information includes:

[0165] In response to the current air conditioning control mode being the heating mode and the current air conditioning internal and external circulation mode being the automatic mode, or the current air conditioning control mode being the ventilation mode and the current air conditioning internal and external circulation mode being the automatic mode, or the current air conditioning control mode being the cooling mode and the temperature inside the vehicle being less than or equal to the temperature outside the vehicle, an energy-saving full internal circulation start instruction is generated. The energy-saving full internal circulation start instruction is used to switch the current internal and external circulation mode of the air conditioning to the full internal circulation mode. The instruction category of the energy-saving full internal circulation start instruction is the energy-saving category.

[0166] 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 in a distributed scenario and performed by multiple devices working together. In such a distributed scenario, one of the multiple devices may only perform one or more steps of the method of the embodiment of the present application, and the multiple devices will interact with each other to complete the method.

[0167] It should be noted that the above description is limited to some embodiments of the present application. Other embodiments are within the scope of the appended claims. In some cases, the actions or steps recited in the claims may be performed in an order different from that described in the above embodiments and still achieve the desired results. Furthermore, the processes depicted in the accompanying drawings do not necessarily require the specific order or sequential order shown to achieve the desired results. In certain embodiments, multitasking and parallel processing are also possible or may be advantageous.

[0168] Based on the same technical concept, corresponding to any of the above-mentioned embodiment methods, the present application also provides a vehicle air-conditioning control device.

[0169] Referring to FIG3 , a vehicle air conditioning control device includes:

[0170] An acquisition module 302 is configured to acquire the current speed of the vehicle;

[0171] The adjustment module 304 is configured to adjust the air conditioning external circulation damper opening of the vehicle in response to the current vehicle speed exceeding the first preset vehicle speed according to the current vehicle speed and a preset adjustment rule, wherein in the preset adjustment rule, the current vehicle speed is negatively correlated with the air conditioning external circulation damper opening.
