[0056] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0057] This application provides a vehicle air conditioning control method, which is applied to a vehicle controller. Referring to FIG1 , the method includes the following steps:

[0058] Step 102: 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.

[0059] Specifically, air conditioning adjustment commands are generated based on the vehicle's current driving information and surrounding environmental information. Driving information is obtained from various on-board controllers or processors, and surrounding environmental information can be obtained from on-board sensors such as temperature sensors, humidity sensors, and cameras. The vehicle's current operating conditions may include multiple different conditions, such as defogging, the presence of air pollutants outside the vehicle, and energy-saving. Different air conditioning adjustment commands are generated for each operating condition, and each corresponds to different air conditioning control logic. In this embodiment, air conditioning adjustment commands are divided into three categories: safety, environmental, and energy-saving. Safety-related commands are those that can impact driving safety, such as defogger commands, which can eliminate fog on the windshield and prevent obstruction to the driver's vision, creating a driving safety hazard. Environmental-related commands are those that can affect the interior environment, such as pollutant control commands, ventilation commands, and window washing commands. Environmental-related air conditioning adjustment commands control the air conditioning's internal and external circulation systems to ensure excellent air quality within the vehicle, 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.

[0060] 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.

[0061] Step 104 : Determine a target adjustment instruction from at least one air conditioning adjustment instruction according to a preset priority order corresponding to the instruction category.

[0062] 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.

[0063] Step 106: Adjust the internal and external circulation modes of the air conditioner according to the target adjustment instruction.

[0064] 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.

[0065] Based on steps 102 to 106 above, this embodiment provides a vehicle air conditioning control method, including 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 are adjusted based on the target adjustment command to ensure vehicle driving safety and comfort, thereby enhancing the user's driving experience.

[0066] 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.

[0067] In some embodiments, referring to FIG2 , determining a target adjustment instruction from at least one air conditioning adjustment instruction according to a preset priority order corresponding to the instruction categories includes the following steps:

[0068] Step 202: Determine the category priority corresponding to each air conditioning adjustment instruction according to the category priority order in the 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;

[0069] Step 204: In response to the presence of multiple air conditioning adjustment instructions having the same category priority, determine the instruction priority of each of the multiple air conditioning adjustment instructions according to the instruction priority order in the preset priority order;

[0070] Step 206: The air conditioning adjustment instruction with the highest priority among all the air conditioning adjustment instructions is used as the target adjustment instruction.

[0071] 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.

[0072] 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.

[0073] 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:

[0074] 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.

[0075] 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 continues 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.

[0076] 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.

[0077] 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.

[0078] In some embodiments, generating at least one air conditioning adjustment instruction includes:

[0079] Obtain vehicle information and / or environmental information;

[0080] At least one air-conditioning adjustment instruction is generated according to the vehicle information and / or the environmental information.

[0081] Specifically, vehicle information refers to information related to vehicle driving and can be obtained from various controllers or components on the vehicle. Examples include vehicle speed and operating conditions. Environmental information includes the temperature inside and outside the vehicle, humidity, pollutant concentration, and so on, which can be obtained through various types of sensors installed on the vehicle. Vehicle information and environmental information can represent the vehicle's current driving state and environmental conditions. If the driving state and environmental conditions meet the corresponding preset operating conditions, corresponding air conditioning adjustment instructions are generated. The air conditioning adjustment instruction generation method of this embodiment can accurately generate adjustment instructions to further adjust the air conditioning to meet the user's vehicle needs.

[0082] The following describes a specific method for generating an air conditioning adjustment instruction through several embodiments.

[0083] 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;

[0084] Generating at least one air conditioning adjustment instruction according to vehicle information and / or environmental information includes:

[0085] The dew point is calculated based on the humidity inside the front windshield and the temperature inside the vehicle;

[0086] Determine the fogging risk level based on the front windshield surface temperature and dew point;

[0087] 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.

[0088] This embodiment is aimed at the defogging external circulation opening instruction, which corresponds to the defogging working condition. First, determine whether the front windshield of the vehicle has a risk of fogging based on the vehicle information. The humidity sensor obtains the humidity inside the front windshield, and the temperature sensor obtains the surface temperature of the front windshield and the temperature inside the vehicle. The dew point is calculated according to the humidity inside the front windshield and the temperature inside the vehicle through formulas (1)-(2).

[0089] Among them, T d represents the dew point, T represents the interior temperature, RH represents the humidity inside the windshield, and a and b are constants. The fogging risk level is determined based on the windshield surface temperature and dew point. When the windshield surface temperature is greater than the dew point, the fogging risk level is considered zero risk; when the windshield surface temperature is equal to the dew point, the fogging risk level is considered low risk; and when the windshield surface temperature is less than the dew point, the fogging risk level is considered high risk. The preset threshold level can be low risk. In response to the fogging risk level exceeding low risk, a defogging external circulation start instruction is generated. The defogging external circulation start instruction includes a target external circulation damper opening, and the current external circulation damper opening is adjusted based on the target external circulation damper opening. The external circulation damper opening is positively correlated with the fogging risk level. That is, the higher the fogging risk level, the larger the external circulation damper opening, and the lower the fogging risk level, the lower the external circulation damper opening. The air conditioner's external circulation damper opening is adjusted based on the fogging risk level to prevent fogging of the vehicle's windshield, which could affect driving safety. For example, when the fogging risk level is low, the external circulation damper opening is increased by a first preset amount, for example, by 30%, based on the current opening. When the fogging risk level is high, the external circulation damper is fully opened, setting it to full external circulation.

[0090] 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.

[0091] 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:

[0092] 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.

[0093] The present embodiment targets the pollutant full internal circulation instruction, and the corresponding working condition is the vehicle external pollutant working condition. The vehicle external pollutants may 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, the concentration of sulfur oxides is detected by a sulfur oxide sensor, and the concentration of nitrogen oxides is detected by a nitrogen oxide sensor. When the concentration of pollutants outside the vehicle exceeds a preset concentration threshold, it indicates that the concentration of pollutants outside the vehicle is too high, and the external circulation needs to be closed immediately, generating a pollutant full internal circulation instruction to control the air conditioning controller to close the external circulation and start the full internal circulation. Exemplarily, the preset concentration threshold can be 500PPM.

[0094] In addition, when the concentration of pollutants outside the vehicle exceeds a preset concentration threshold, the external circulation can be appropriately turned on to meet the ventilation needs inside the vehicle. In response to the concentration of pollutants outside the vehicle being less than or equal to the minimum concentration threshold, the internal and external circulation mode of the air conditioner is switched to full external circulation. For example, the minimum concentration threshold can be 200 PPM. When the concentration of pollutants outside the vehicle is less than or equal to 200 PPM, it will not affect human health, and the full external circulation can be turned on to ensure the ventilation rate inside the vehicle. In response to the concentration of pollutants outside the vehicle being between the minimum concentration threshold and the preset concentration threshold, the external circulation damper opening and the internal circulation damper opening can be proportionally adjusted according to the preset concentration adjustment rule. The preset concentration adjustment rule calibrates the corresponding relationship between the concentration of pollutants outside the vehicle and the opening of the external circulation damper and the opening of the internal circulation damper. The higher the concentration of pollutants outside the vehicle, the smaller the opening of the external circulation damper 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 internal circulation damper to ensure air flow inside the vehicle. The higher the concentration of pollutants outside the vehicle, the wider the external circulation damper opening, ensuring the required ventilation rate inside the vehicle. At the same time, the smaller the internal circulation damper opening, the more air flow inside the vehicle relies on the external circulation. This embodiment of the air conditioning control method ensures both the quality of the air inside the vehicle and the ventilation requirements inside the vehicle. When the concentration of pollutants outside the vehicle exceeds the standard, the external circulation is immediately closed, ensuring the physical and mental health of the vehicle occupants and improving driving comfort.

[0095] In addition to controlling the air conditioning according to the concentration of pollutants outside the vehicle, the air conditioning can also be controlled according to the degree of congestion in the vehicle to ensure the air quality inside the vehicle.

[0096] In some embodiments, the vehicle air conditioning control method also includes: in response to the current vehicle speed exceeding a second preset speed, or there are no other vehicles within a preset range in front of the vehicle, switching the internal and external circulation mode of the air conditioning to full external circulation, wherein the second preset speed is less than the first preset speed.

[0097] This embodiment targets congested conditions. The distribution of vehicles within a preset range ahead of the vehicle can be determined using images captured by a camera mounted in front of the vehicle. When congestion is severe, there may be a large amount of exhaust gas around the vehicle, resulting in poor air quality. Therefore, the external circulation system needs to be disabled to prevent outside air from entering the vehicle and affecting the air quality. When congestion is less severe, the external circulation system can 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 the external circulation system needs 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.

[0098] 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:

[0099] 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.

[0100] 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.

[0101] 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 water vapor content.

[0102] 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.

[0103] 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:

[0104] 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.

[0105] 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.

[0106] 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:

[0107] 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.

[0108] This embodiment targets the energy-saving full internal circulation activation instruction. Generally, activating the internal circulation consumes less energy than activating the external circulation, effectively saving vehicle energy and improving vehicle range. Activating the energy-saving full internal circulation activation instruction requires certain prerequisites, including: the current air conditioning control mode is heating mode and the current air conditioning internal and external circulation mode is automatic mode; the current air conditioning control mode is ventilation mode and the current air conditioning internal and external circulation mode is automatic mode; or the current air conditioning control mode is cooling mode and the vehicle interior temperature is less than or equal to the outside temperature.

[0109] If the current air conditioning control mode is heating mode and the current air conditioning internal and external circulation mode is automatic mode, the air conditioning internal and external circulation mode is adjusted to full internal circulation mode, which can minimize the loss of hot air in the car and quickly increase the temperature in the car to meet user needs. If the current air conditioning control mode is ventilation mode and the current air conditioning internal and external circulation mode is automatic mode, the air conditioning internal and external circulation mode is adjusted to full internal circulation mode, and the air flow in the car is achieved through internal circulation. Full internal circulation is more energy-efficient than full external circulation, effectively reducing vehicle energy consumption. If the current air conditioning control mode is cooling mode and the temperature in the car is less than or equal to the outside temperature, the air conditioning internal and external circulation mode is adjusted to full internal circulation mode to prevent the air in the car from losing to the outside, causing cold air loss. Turning on full internal circulation can improve the cooling efficiency of the air in the car and reach the driver's required temperature as soon as possible.

[0110] Furthermore, if the air conditioner's current air conditioning control mode is heating mode, and the internal and external circulation mode set by the driver is external circulation mode, then, in the current external circulation mode, the internal circulation damper opening is adjusted to the maximum value to reduce the loss of hot air inside the vehicle, thereby quickly raising the vehicle interior temperature to the driver's desired temperature. If the air conditioner's current air conditioning control mode is ventilation mode, and the current internal and external circulation mode is pre-set to external circulation mode, then the air conditioner's internal and external circulation mode is adjusted to full external circulation mode to complete vehicle interior ventilation at the fastest rate, thereby improving the air quality inside the vehicle. If the air conditioner's current air conditioning control mode is cooling mode, the vehicle interior and exterior temperatures must also be considered. If the vehicle interior temperature is greater than the exterior temperature, the air conditioner's internal and external circulation mode is adjusted to full external circulation mode, allowing a large amount of cool air outside to enter the vehicle, accelerating the cooling efficiency of the vehicle interior air, saving energy, and reducing the air conditioning load. The vehicle air conditioning control method of this embodiment further reduces vehicle energy consumption and improves driving comfort by finely adjusting the air conditioner's internal and external circulation modes, while being able to quickly meet the driver's requirements for interior temperature and air quality.

[0111] In order to further improve the driving comfort of the vehicle, before the driver uses the vehicle, the air conditioner can be remotely started and the internal and external circulation modes of the air conditioner can be adjusted according to the driver's actual needs. The specific adjustment method is explained in the following embodiment.

[0112] In some embodiments, the vehicle air conditioning control method further includes:

[0113] Get the current control mode of the air conditioner;

[0114] 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;

[0115] 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;

[0116] 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;

[0117] 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.

[0118] Specifically, the driver can remotely turn on the air conditioning or schedule it before using the vehicle, ensuring that the interior temperature or air quality meets the driver's desired setting. 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 vehicle 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 rapidly ventilate the interior air, accelerating the exchange of air between the interior and exterior. If the driver remotely selects cooling mode, both 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. This accelerates cooling efficiency, saves energy, and reduces 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.

[0119] When the vehicle is driving and it rains, the driver usually closes the windows and sunroof to prevent water from entering the car, but does not make targeted adjustments to the internal and external circulation modes of the air conditioner. If the current water vapor content is high and the air conditioner's external circulation damper is also open widely, the water vapor outside the car can enter the car through the external circulation channel, causing certain damage to the performance of the components inside the car. If the current water vapor content is low and the air conditioner's external circulation is closed, the ventilation needs cannot be met, and the air quality inside the car cannot be guaranteed. In view of this, the present application proposes a vehicle air conditioning control method that can ensure that the vehicle is ventilated while preventing excessive water vapor from entering the vehicle, thereby ensuring the air quality inside the vehicle and preventing water vapor from damaging the performance of vehicle components.

[0120] This application proposes a vehicle air conditioning control method, which is applied to a vehicle controller. Referring to FIG3 , the specific method includes the following steps:

[0121] Step 302: Obtain the current water vapor content outside the vehicle.

[0122] The current water vapor content is the ratio of the mass of water vapor in the humid air outside the vehicle to the total mass of the humid air. This current water vapor content can be collected by a water vapor detection sensor installed outside the vehicle. This information can be used to determine whether it is raining or whether the air humidity on the road is high.

[0123] Step 304: Determine a target opening according to the current water vapor content and a first preset adjustment relationship, and adjust the air conditioner's external circulation damper opening from the current opening to the target opening; wherein, in the first preset adjustment relationship, the current water vapor content is negatively correlated with the target opening.

[0124] Specifically, when the current water vapor content exceeds the minimum limit, it can be considered that the current working condition is raining, or the current air humidity is high. The first preset adjustment relationship pre-calibrates the corresponding relationship between the water vapor content and the external circulation damper opening. The greater the current water vapor content, the smaller the external circulation damper opening. When the current water vapor content is large, the external circulation damper opening is small, which can effectively prevent the water vapor outside the vehicle from entering the vehicle through the external circulation channel. When the current water vapor content is small, 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, improve the efficiency of ventilation, and improve the air quality in the vehicle. After determining the current water vapor content, the target opening corresponding to the current water vapor content can be determined according to the first preset adjustment relationship. The target opening is the expected opening of the external circulation damper under the current water vapor content. The opening of the air conditioner's external circulation damper is adjusted from the current opening to the target opening to achieve flexible adjustment of the air conditioner's external circulation state.

[0125] Based on steps 302 to 304 above, the vehicle air conditioning control method provided in this embodiment includes obtaining the current water vapor content outside the vehicle, determining a corresponding target opening based on the current water vapor content and a first preset adjustment relationship, and different current water vapor contents correspond to different target openings, and the current water vapor content and the target opening are negatively correlated. The greater the current water vapor content, the smaller the target opening, which can effectively prevent a large amount of water vapor from entering the vehicle while meeting the ventilation requirements. The smaller the current water vapor content, the larger the target opening, while meeting the requirements of preventing water vapor from entering the vehicle, and maximizing the ventilation volume to improve the air quality inside the vehicle. After determining the target opening, the air conditioning's external circulation damper opening is adjusted from the current opening to the target opening, achieving the purpose of flexibly adjusting the air conditioning's external circulation damper opening. This application prevents excessive water vapor from entering the vehicle while ensuring continuous ventilation of the vehicle, ensuring the air quality inside the vehicle and preventing water vapor from damaging the performance of vehicle components.

[0126] Furthermore, after the air conditioner's external circulation damper opening is controlled according to different water vapor contents through the above-mentioned embodiment, the air conditioner's internal and external circulation modes can be finely controlled in combination with the current vehicle speed, and the air conditioner's internal and external circulation can be effectively utilized to improve the vehicle's driving safety, reduce the air conditioning load, and increase the vehicle's cruising range, etc.

[0127] In some embodiments, referring to FIG4 , the vehicle air conditioning control method further includes the following steps:

[0128] Step 402: Obtain the current speed of the vehicle.

[0129] Step 404: In response to the current vehicle speed exceeding a preset vehicle speed threshold, the inner circulation damper opening and the outer circulation damper opening of the air conditioner are adjusted according to the current vehicle speed and a second preset adjustment relationship, wherein, in the second preset adjustment relationship, the current vehicle speed is positively correlated with the inner circulation damper opening, and the current vehicle speed is negatively correlated with the outer circulation damper opening.

[0130] Specifically, the preset vehicle speed threshold represents the minimum vehicle speed at which the internal and external circulation modes of the air conditioner need to be adjusted according to the vehicle speed. The second preset adjustment relationship calibrates the correspondence between the vehicle speed and the internal circulation damper opening and the external circulation damper opening. The faster the vehicle speed, the larger the corresponding internal circulation damper opening and the smaller the external circulation damper opening. This is because when the vehicle speed increases and the external circulation is turned on, more fresh air enters the car, and the air inside the car is lost to the outside of the car. If the air conditioner is in cooling or heating mode, it will cause a certain amount of energy loss. Therefore, it is necessary to reduce the external circulation damper opening. At the same time, increasing the internal circulation damper opening can reduce the air conditioning load, achieve energy-saving effects, and thus improve the vehicle's cruising range.

[0131] It should be noted that in this embodiment, the inner circulation damper and the outer circulation damper of the air conditioner are controlled separately. Adjusting the opening of the inner circulation damper does not affect the opening of the outer circulation damper, and adjusting the opening of the outer circulation damper does not affect the opening of the inner circulation damper.

[0132] It should be noted that, on the basis of adjusting the external circulation damper opening according to the current water vapor content, 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 embodiment.

[0133] In some embodiments, the external circulation damper opening is greater than a preset minimum opening threshold.

[0134] 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%.

[0135] The above embodiment describes how to adjust the internal and external circulation modes of the air conditioner after the current vehicle speed exceeds the preset vehicle speed threshold. If the current vehicle speed does not exceed the preset vehicle speed threshold, the internal and external circulation modes of the air conditioner are adjusted through the following embodiment.

[0136] In some embodiments, the vehicle air conditioning control method further includes:

[0137] In response to the current vehicle speed not exceeding the preset vehicle speed threshold, the external circulation air door opening is restored to an opening before the target opening.

[0138] Exemplarily, the preset vehicle speed threshold may be 10 km / h. If the current vehicle speed does not exceed the preset vehicle speed threshold, it indicates that the current vehicle speed is relatively slow, and the rainfall and vehicle speed have little impact on the vehicle interior environment. There is no need to adjust the internal and external circulation modes of the air conditioner, and the current state of the air conditioner can be maintained. The opening before the target opening is the external circulation damper opening of the air conditioner before the external circulation damper opening of the air conditioner is adjusted according to the current water vapor content. Exemplarily, the current damper opening is 60%. If the current water vapor content is large, the external circulation damper opening is reduced to 30% according to the current water vapor content, and the current vehicle speed is judged. If the current vehicle speed is low, the external circulation damper opening is restored to 60% to increase the ventilation rate and improve the air quality in the vehicle.

[0139] The following embodiment illustrates a method for adjusting the internal and external circulation modes of an air conditioner under window washing conditions.

[0140] In some embodiments, the vehicle air conditioning control method further includes:

[0141] Get the current working condition of the vehicle;

[0142] In response to the current operating condition being the window washing condition, the opening of the air conditioner's external circulation damper is reduced to zero.

[0143] Specifically, due to the complexities of vehicle driving scenarios and road conditions, vehicles experience a variety of operating conditions during driving. Different control strategies can be employed based on these conditions to ensure vehicle stability and comfort, and enhance the driver's driving experience. The window-washing condition involves spraying glass water on the outside of the windshield to clean it. Glass water typically contains chemicals that are harmful to the human body and have a pungent odor. To prevent chemical odors from entering the vehicle during the window-washing condition and potentially affecting the health of those inside, the external circulation damper is adjusted to zero, effectively shutting off the external circulation. This prevents odors from entering the vehicle through the external circulation channel, ensuring that the air quality inside the vehicle is not affected and enhancing the driver's driving experience.

[0144] 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 water vapor content.

[0145] In addition to the window washing working condition described in the above embodiment, it also includes a car washing working condition. The following embodiment illustrates a method for adjusting the internal and external circulation modes of the air conditioner under the car washing working condition.

[0146] In some embodiments, the vehicle air conditioning control method further includes: obtaining a current operating condition of the vehicle;

[0147] In response to the current operating condition being a car wash operating condition, the opening of the air conditioner's external circulation damper is reduced to zero.

[0148] Specifically, 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.

[0149] During vehicle driving, if the vehicle is moving at a high speed and a certain external circulation is activated, the amount of air entering the vehicle from outside increases compared to when the vehicle is moving at a slower speed. This in turn increases the amount of air squeezed out of the vehicle, causing some air to be lost from the vehicle. When the air conditioner is in cooling or heating mode, this air loss from the vehicle will result in some energy loss, increasing the air conditioning load and energy consumption. At the same time, a large amount of outside air enters the vehicle, and the dust particles carried by this outside air have a certain impact on the cleanliness of the air inside the vehicle, causing it to decrease cleanliness and affect driving comfort. In view of this, the present application proposes a vehicle air conditioning control method that reduces air conditioning energy loss while preventing a decrease in air quality inside the vehicle.

[0150] This application proposes a vehicle air conditioning control method, referring to FIG5 , comprising the following steps:

[0151] Step 502: Obtain the current speed of the vehicle.

[0152] 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.

[0153] Step 504: In response to the current vehicle speed exceeding a first preset vehicle speed, the air conditioning external circulation damper opening of the vehicle is adjusted 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.

[0154] 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.

[0155] Based on steps 502 to 504 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.

[0156] 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 completed 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.

[0157] 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.

[0158] 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.
