[0099] As mentioned in the background technology section, as people pay more and more attention to environmental protection and low carbon, the pace of development of new energy vehicles has also accelerated significantly. The integration of automobiles with related technologies in the fields of energy, transportation, information and communications has accelerated, and electrification, networking and intelligence have become the development trend and trend of the automobile industry. New technologies for new energy vehicles have sprung up, for example:

[0100] The application number is CN202410658157.7, the publication number is CN118238797B, and the invention name is New Energy Vehicle Energy Intelligent Management System, Control Method and Related Equipment;

[0101] The application number is CN202410672579.X, the publication number is CN118597091A, and the invention name is new energy vehicle energy intelligent management method, system and related equipment;

[0102] The application number is CN202010470247.5, the publication number is CN113734146B, and the invention name is vehicle driving mode selection method, device, equipment and medium;

[0103] They all describe hybrid technology that is mainly electric, and has multiple advantages such as being fast, economical, quiet, smooth, and green.

[0104] The application number is CN202211678720.4, the publication number is CN117382629B, and the invention name is vehicle power control method, device, medium, vehicle controller and vehicle;

[0105] The application number is CN202311164098.X, the publication number is CN116890770B, and the invention name is vehicle control system, method and vehicle;

[0106] The application number is CN202311170393.6, the publication number is CN117533292B, and the invention name is vehicle control system, control method, controller and vehicle;

[0107] Both describe a new energy power system with four wheel-side motors independently driven as the core, which greatly improves the safety and power of new energy vehicles.

[0108] During the operation of car air conditioning, especially at the initial startup, two problems are often encountered: the air supply has an odor and the temperature comfort is not good.

[0109] First, regarding the problem of odor in the air supply, this is mainly due to the fact that the fine dust and impurities in the air will adhere to the microchannel structure of the heat exchanger after entering the air conditioning box. These tiny particles provide a breeding ground for bacteria and mold, especially in the dark and humid environment inside the air conditioning box, where bacteria and mold grow more rapidly. As the air is supplied by the air conditioner, the odors generated by these bacteria and mold will be brought into the passenger compartment, causing discomfort to the passengers.

[0110] Secondly, the temperature comfort when the air conditioner is first started is also an issue that needs attention. In hot weather, the air inlet temperature of the air conditioner is high, and the cooling effect is not ideal, resulting in a slow air supply and cooling speed. This makes the first breath of fresh air when the air conditioner is first started have a large difference from the temperature expected by the passengers. The hot air blows directly on the passengers, causing them to feel suddenly stuffy and uncomfortable. On the contrary, in a cold environment, the first breath of fresh air when the air conditioner is first started often makes the passengers feel suddenly cold and uncomfortable.

[0111] In the process of realizing the present invention, the applicant discovered that in order to solve the above-mentioned problems, the related technology turns on the foot blowing mode in the initial startup stage of the air conditioner to prevent the first breath of fresh air from blowing directly on the passenger's face, thereby reducing the passenger's intuitive feeling of the fresh air odor and wind temperature. However, in the foot blowing mode, the air supplied by the air conditioner still enters the passenger compartment, and the bacteria, dust and odor in the fresh air cannot be removed, and passengers with keen sense of smell and temperature will still feel uncomfortable. Alternatively, the odorous gas in the air conditioning box can be discharged by the reverse rotation of the blower. This requires the installation of a blower that can supply air in both directions, and the air inlet damper and the exhaust damper 202 need to be equipped with their own control mechanisms. Therefore, the cost of the air conditioning box is increased, and the structure of the air conditioning box is complicated and bloated, which is not conducive to layout and installation.

[0112] In order to solve the above problems and improve the use comfort of air conditioning, the present invention provides a control method for a vehicle air conditioning system that can improve the comfort of fresh air temperature and remove odor.

[0113] The technical solution of the present invention is further described in detail below through specific embodiments.

[0114] refer to Figure 1, is a schematic diagram of a vehicle air conditioning system provided in an embodiment of the present invention.

[0115] The vehicle air conditioning system includes an air conditioning box housing 10 , an internal circulation air inlet 101 , an external circulation air inlet 102 , an exhaust air outlet 201 , a component to be deodorized 301 , a control damper component 401 and a blower 501 .

[0116] Among them, the internal circulation air inlet 101 is provided on the air conditioning box shell 10, and is selectively connected to the cabin of the target vehicle through the internal and external circulation damper 103. The external circulation air inlet 102 is provided on the air conditioning box shell 10, and is selectively connected to the external environment of the target vehicle through the internal and external circulation damper 103. The exhaust air outlet 201 is provided on the air conditioning box shell 10, and is selectively connected to the external environment of the target vehicle through the exhaust damper 202, and is responsible for discharging the treated air out of the vehicle. The deodorizing component 301 is arranged inside the air conditioning box shell 10, including a filter element 3011, an evaporator 3012 and a heating component 3013. The filter element 3011 can filter out dust and particles in the air, the evaporator 3012 is used for cooling, and the heating component 3013 provides warm air. The control damper assembly 401 is arranged inside the air conditioning box housing 10, and includes a first control damper 4011, a second control damper 4012, a face damper 4013, a foot damper 4014 and a defrost damper 4015. The control damper assembly 401 can control the flow direction and distribution of air to meet the needs of different air conditioning control modes. The first control damper 4011 is arranged correspondingly with the heating assembly 3013 to control the ventilation state of the heating assembly 3013. Among them, the defrost damper 4015 is arranged coaxially with the exhaust damper 202. The blower 501 is arranged inside the air conditioning box housing 10, and is used to suck the air in the cabin of the target vehicle into the air conditioning box housing 10 through the internal circulation air inlet 101 or / and suck the air of the external environment of the target vehicle into the air conditioning box housing 10 through the external circulation air inlet 102. The blower 501 has sufficient suction and air supply capacity to ensure effective circulation and distribution of air.

[0117] As an optional embodiment, the heating component 3013 of the vehicle air conditioning system further includes an internal condenser, which is used to cool and convert the high-temperature and high-pressure refrigerant vapor into liquid, thereby releasing heat to the environment outside the vehicle. The heating component 3013 can be any combination of a heater core, a PTC heater, and an internal condenser.

[0118] The defrost damper 4015 is coaxially arranged with the exhaust damper 202, and the exhaust vent 201 is located at the front of the vehicle body, facing the front cabin, and is connected to the interior of the air conditioning box through the exhaust vent 201 (or exhaust duct) and the exhaust damper 202. The exhaust damper 202 is connected to the defrost damper 4015 via a common rotating shaft.

[0119] refer to Figure 2 , which is a schematic diagram of the structure of the exhaust damper, the defrost damper and the shared shaft clutch device.

[0120] The damper shares the rotating shaft 30 and the rotating shaft gear 31 to form a clutch device, which controls the opening and closing of the exhaust damper 202201 and the defrost damper 4015 in steps through the gear meshing transmission.

[0121] refer to Figure 3 , which is a flow chart of the control principle of the clutch device.

[0122] When the vehicle air conditioning system is started, the common shaft is placed in the initial position L0 ( Figure 2 At this time, the sleeve gear and the shaft gear 31 are separated, and the clutch device is not linked with the exhaust damper 202 and the defrost damper 4015. When the air conditioner controller receives the driving instruction of the defrost damper 4015, the motor pulls the common shaft to move the step displacement X1 along the A direction, so that the shaft gear meshes with the gear of the sleeve 32 of the defrost damper 4015, and the clutch device and the defrost damper 4015 form a linked state. Then the motor drives the common rotating shaft to rotate, and drives the defrost damper 4015 to rotate to the specified position through the meshing gear. The motor stops rotating and pulls the common rotating shaft along the B direction step displacement X1, so that the common rotating shaft returns to the initial position L0, and the clutch device and the defrost damper 4015 are disengaged; when the air conditioning controller receives the driving instruction of the exhaust damper 202, the motor pulls the common rotating shaft along the B direction step displacement X2, so that the rotating shaft gear 31 and the gear of the exhaust damper 202 sleeve 33 are meshed, and the clutch device and the exhaust damper 202 form a linkage state. At this time, the rotation of the motor can drive the exhaust damper 202 to rotate through the common rotating shaft and gear transmission. After completing the task, the motor pulls the common rotating shaft along the A direction step displacement X2 back to the initial position L0, and the clutch device and the exhaust damper 202 are disengaged.

[0123] Among them, the exhaust air duct is used to discharge the air in the air conditioning box to the air duct outside the vehicle, the inlet is connected to the air conditioning box shell, and the outlet is connected to the front cabin. The exhaust air damper 202 is used to control the air damper flowing through the exhaust air duct, and is located at the connection between the exhaust air duct and the air conditioning box. The damper shaft sleeve is located at the rotating shaft position of the defrost damper 4015 and the exhaust damper 202, and is a hollow shaft sleeve with a gear, which can realize the rotation transmission from the shaft to the damper through the engagement with the shaft gear 31. The damper common rotating shaft 30, the defrost damper 4015 and the exhaust damper 202 common rotating shaft, is provided with a bidirectional rotating shaft gear 31, which can realize the step-by-step control of the rotation of the two dampers by one rotating shaft. The rotating shaft gear 31 is a bidirectional gear arranged on the damper common rotating shaft 30, and can realize the linkage between the damper common rotating shaft 30 and the defrost and exhaust dampers 202 through the engagement with the damper shaft sleeve gear. The clutch device is a gear clutch device composed of a common damper shaft 30 and the defrost damper 4015 and the exhaust damper 202 through a damper shaft sleeve gear and a shaft gear 31, and the linkage between the shaft and different dampers is achieved through the axial movement of the common damper shaft 30.

[0124] According to the above content, the present invention sets the defrost damper 4015 and the exhaust damper 202 coaxially. Through the coaxial setting and the clutch device, a compact design of the damper control is achieved, saving space. The motor traction and gear meshing transmission ensure the precise control of the opening and closing of the damper, and improve the stability and reliability of the system. The design of the clutch device allows the defrost damper 4015 and the exhaust damper 202 to be independently controlled, meeting the needs of the vehicle air conditioning system under different working conditions.

[0125] In addition, the exhaust damper 202 can be coaxially arranged with any at least one damper adjacent thereto. In practical applications, the exhaust damper 202 can also be coaxially arranged with the face damper (when the exhaust damper 202 is adjacent to the face damper), and the exhaust damper 202 can also be coaxially arranged with the foot damper (when the exhaust damper 202 is adjacent to the foot damper). Alternatively, the exhaust damper 202 may not be coaxially arranged with any damper.

[0126] refer to Figure 4 , which is a flow chart of a control method for a vehicle air conditioning system provided by an embodiment of the present invention.

[0127] Step S401, receiving a start instruction, obtaining real-time status information of a target vehicle, and determining whether the real-time status information meets a preset condition.

[0128] Step S402, in response to the real-time status information satisfying the preset conditions, the exhaust damper is controlled to open and the damper assembly is controlled so that after the air in the vehicle passes through the component to be deodorized, the odorous gas in the component to be deodorized is discharged outside the vehicle through the exhaust vent.

[0129] The control method of the vehicle air conditioning system provided by the present invention is provided with at least two deodorization modes: a quick deodorization mode and a deep deodorization mode, which can quickly remove the odor of the "first breath" of fresh air at the initial stage of air conditioning startup. The present invention can control the startup of different deodorization modes by judging conditions. In the deodorization mode, the odorous gas in the air conditioning box can be discharged out of the vehicle through the front cabin through the dedicated exhaust damper and exhaust duct. The exhaust damper and the exhaust duct have a large flow area, a large odorous gas exhaust flow rate, and a short air conditioning deodorization time.

[0130] In a specific implementation, air enters the air conditioning box from the internal circulation air inlet. Next, the air is filtered through the filter element to remove dust and impurities. The air is then cooled or dehumidified through the evaporator (if the system is in cooling mode). After that, the air has two possible directions of flow: part of the air can flow directly to the exhaust damper and be discharged out of the vehicle through it. Another part of the air (if the first control damper is open, and the heating component is present and has been started) will flow through the heating component for heating, and then flow to the exhaust damper to be discharged out of the vehicle.

[0131] Specifically, when both the first control damper and the second control damper are open, the air will be split, with one part being discharged directly and the other part passing through the heating component. When the first control damper is open and the second control damper is closed, all the air will flow through the heating component. When the first control damper is closed and the second control damper is open, the air will not flow through the heating component and will be directly discharged outside the vehicle.

[0132] As an optional embodiment, after receiving the start instruction, the method further includes: controlling the internal and external circulation dampers to switch to the internal circulation mode.

[0133] Specifically, the vehicle air conditioning system receives a start command from inside or outside the vehicle, which is usually triggered by the user through the control panel, smart device or the vehicle's own sensor. Before receiving the start command and preparing to enter the deodorization mode, the system first switches the internal and external circulation dampers to the internal circulation mode. This step helps reduce the entry of external pollutants and ensures that the air in the passenger compartment of the target vehicle is regulated synchronously while dealing with the odor in the vehicle.

[0134] As an optional embodiment, after controlling the opening of the damper assembly, the method further includes: controlling the starting of the blower.

[0135] After controlling the opening of the control damper assembly, the system controls the start of the blower. The start of the blower can form the flow of air from the vehicle to the air conditioning box, ensuring that the air can pass through the filter element, evaporator and other components more effectively. This step determines the air flow speed and deodorization efficiency.

[0136] As an optional embodiment, the real-time status information includes the shutdown duration of the blower; obtaining the real-time status information of the target vehicle, and judging whether the real-time status information meets a preset threshold, including: obtaining the shutdown duration of the blower, and judging whether the shutdown duration reaches a preset shutdown duration; in response to the shutdown duration reaching the preset shutdown duration, determining that the real-time status information meets a preset condition.

[0137] Specifically, after receiving the start-up instruction, the control method of the vehicle air conditioning system is performed according to the following steps, especially when considering the blower shutdown time as the start-up condition of the deodorization function: the vehicle air conditioning system receives a start-up instruction from a user or a vehicle system, triggering the acquisition and judgment process of real-time status information. The system first obtains the length of time since the blower was last shut down, that is, the shutdown time. This information can be collected by a timer or sensor inside the vehicle. The system compares the acquired shutdown time with a preset shutdown time threshold. The preset shutdown time is set based on factors such as vehicle usage habits and air quality changes, and is intended to ensure that after the blower is shut down for a period of time, if it is started again, the deodorization function can be triggered to improve the air quality inside the air conditioning box and in the car. If the shutdown time reaches or exceeds the preset shutdown time, the system determines that the real-time status information meets the preset conditions, that is, the deodorization function needs to be started. At this time, the system can continue to execute subsequent steps, such as controlling the opening of the control damper assembly, starting the blower (if it has not yet started), etc. Depending on the system design and user needs, it may be necessary to switch the internal and external circulation dampers to the internal circulation mode before starting the deodorization function to reduce the entry of external pollutants and treat the air in the passenger compartment. By introducing the blower shutdown time as one of the conditions for starting the deodorization function, this method can more intelligently determine when the deodorization function needs to be started, avoiding unnecessary energy consumption and noise. At the same time, combined with comprehensive monitoring of real-time status information and precise damper control, an efficient and intelligent in-vehicle air management system is formed.

[0138] As an optional embodiment, determining whether the downtime duration reaches the preset downtime duration includes: determining whether the downtime duration reaches the preset downtime duration based on the downtime duration, the first preset duration and the second preset duration; in response to the downtime duration being greater than the first preset duration and less than the second preset duration, or in response to the downtime duration being not less than the second preset duration, determining that the downtime duration reaches the preset downtime duration.

[0139] In this embodiment, determining whether the downtime duration reaches the preset downtime duration no longer relies solely on a single threshold, but makes a decision based on a comparison result between the downtime duration and two preset durations (a first preset duration and a second preset duration).

[0140] The first preset time length (t1) is a relatively short time period, which is used to distinguish the boundary of a short-term shutdown. The second preset time length (t2) is a relatively long time period, which is used to distinguish the boundary of a long-term shutdown.

[0141] When the downtime is longer than the first preset time (t1) and shorter than the second preset time (t2), the system may consider that although the downtime is relatively long and reaches the stage of starting the quick deodorization mode, it has not yet reached the stage of needing to start the deep deodorization mode. When the downtime is not shorter than the second preset time (t2), the system considers that the downtime is long enough to need to start the deep deodorization mode to remove the odor that may have accumulated.

[0142] As an optional embodiment, the control damper assembly includes a first control damper and a second control damper, the component to be deodorized includes a filter element, an evaporator, and a heating component, the first control damper and the heating component are correspondingly arranged to control the ventilation state of the heating component; the exhaust damper and the control damper assembly are controlled to open so that after the air inside the vehicle passes through the component to be deodorized, the odorous gas in the component to be deodorized is discharged out of the vehicle through the exhaust vent, including: in response to the shutdown time being greater than the first preset time and less than the second preset time, the first control damper is controlled to be closed and the second control damper is opened, so that the air inside the target vehicle is sucked in, and then passes through the filter element and the evaporator in turn, and the odorous gas in the filter element and the evaporator is taken out and discharged out of the vehicle through the exhaust vent.

[0143] In this embodiment, it can be determined whether to start the deodorization mode according to the downtime, and the air in the vehicle can be purified by precisely controlling the damper assembly. In particular, when the downtime is between the first preset time and the second preset time, the fast deodorization mode can be adopted.

[0144] refer to Figure 5 , which is a schematic diagram of the structure of the vehicle air conditioning system in the rapid deodorization mode.

[0145] Combination Figure 1 and Figure 5, in the quick deodorization mode, open the second control damper and the exhaust damper, close other dampers, and the air enters the air conditioning box from the internal circulation air inlet, and directly enters the front cabin and is discharged outside the car only after passing through the filter element and evaporator. The second control damper is another damper set in the entire internal cross-section of the air conditioning box, which can be used in conjunction with the first control damper to adjust the air flow direction. When the first control damper and the second control damper are all opened, after the air enters the air conditioning box from the internal circulation air inlet, part of it can flow directly to the exhaust vent, and part of it flows through the heating component; when the first control damper is opened and the second control damper is closed, after the air enters the air conditioning box from the internal circulation air inlet, all of it flows through the heating component; when the first control damper is closed and the second control damper is opened, after the air enters the air conditioning box from the internal circulation air inlet, it does not flow through the heating component and flows directly to the exhaust vent.

[0146] As an optional embodiment, the exhaust damper is controlled to open and the damper assembly is controlled so that after the air inside the vehicle passes through the component to be deodorized, the odorous gas in the component to be deodorized is discharged out of the vehicle through the exhaust vent. It also includes: in response to the shutdown time being not less than a second preset time, the first control damper is controlled to open and the second control damper is closed, and after the air inside the target vehicle is sucked in, it passes through the filter element, evaporator and heating component in turn, and the odorous gas in the filter element, evaporator and heating component is taken out and discharged out of the vehicle through the exhaust vent.

[0147] In this embodiment, when the downtime is not less than the second preset time, the system believes that there may be a serious odor in the car, and more thorough odor removal measures need to be taken, that is, a deep odor removal mode is adopted.

[0148] refer to Figure 6 , which is a schematic diagram of the structure of the vehicle air conditioning system in deep deodorization mode.

[0149] Combination Figure 1 and Figure 6 In the deep deodorization mode, open the first control damper and exhaust damper corresponding to the heating component, close other dampers, and the air enters the air conditioning box from the internal circulation air inlet, passes through the filter element, evaporator, and heating component, and enters the front cabin from the exhaust vent, and is discharged outside the vehicle. The first control damper is a "wind shield" set on the heating component. When the first control damper is opened, the air enters the air conditioning box from the internal circulation air inlet and can flow through the heating component. When the first control damper is closed, the air enters the air conditioning box from the internal circulation air inlet and is blocked by the first control damper, and does not need to flow through the heating component.

[0150] When the vehicle air conditioning control system determines that the deep deodorization mode needs to be executed, the system starts to execute a series of preset operations. First, the first control damper corresponding to the heating component is opened. This step ensures that the air can flow through the heating component (such as the heater core). Although the heating function is not necessary during the deodorization process, opening this damper helps to maintain the integrity of the air flow path and deodorize the surface of the microchannel of the heating component to achieve a more comprehensive and in-depth odor removal inside the air conditioning box. The opening of the exhaust damper is the key to exhausting the treated air (containing odorous gases) to ensure that the odor will not remain in the car. Close the damper including the external circulation air inlet and other dampers that may interfere with the air flow path to avoid introducing new pollutants or interfering with the deodorization process. Under the action of the blower, air enters the interior of the air conditioning box from the internal circulation air inlet. The air passes through the filter element, evaporator, and heating component in turn. Among them, the filter element is used to filter out particulate matter and impurities in the air, and may also have a certain deodorization effect. The evaporator is used to cool and dehumidify the air, and is used to cool down the gas entering the air-conditioning box. The heating component (including the heater core, PTC heater, and internal condenser) is used to heat the air, and is used to increase the temperature of the gas entering the air-conditioning box. Both the evaporator and the heating component are fin heat dissipation structures. The microchannels between the fins are easy to harbor dirt and produce fine dust particles and odors after long-term use, so they need to be cleaned and deodorized. The treated air (containing odorous gases) is discharged from the exhaust vent, enters the front cabin, and is finally discharged outside the vehicle. In the deep deodorization mode of the present invention, the air conditioning control system opens the first control damper and the exhaust damper, and the air flows through the evaporator and the heating component and is discharged by the exhaust damper. The surface of each heat exchange core can be cleaned, and the deodorization effect is more thorough.

[0151] As an optional embodiment, the method also includes: in response to the shutdown time being no greater than a first preset time, obtaining the inlet temperature of the gas at the air inlet and the target temperature value; calculating the first difference between the inlet temperature and the target temperature value; in response to the absolute value of the first difference being greater than the preset temperature difference, determining whether the first difference is a positive value; in response to the first difference being a positive value, controlling the first control damper to close and the second control damper to open, and controlling the vehicle air-conditioning system to enter the primary air cooling mode.

[0152] Specifically, if the downtime does not reach the first preset time, the system considers that the current real-time status information does not meet the preset condition. This may mean that the air conditioning system is in continuous working state without being shut down, is shut down for a short time, or the environment level is good, and there is no dust or water vapor on the surface of the internal components of the air conditioning box (such as evaporator, heater core, etc.) during the downtime.

[0153] Furthermore, if the real-time status information does not meet the preset conditions, that is, no odor removal is required, it can be further determined whether the air supply temperature of the air conditioner needs to be adjusted.

[0154] The present invention can regulate the temperature of the "first breath" of fresh air at the initial stage of air-conditioning startup. By setting two initial air temperature pre-control modes, the air-conditioning system can be controlled to enter different modes according to the difference between the air inlet and exhaust air temperatures and the target temperature value, and the air-conditioning air temperature can be pre-processed to increase / lower the temperature, thereby avoiding the problem of passengers suddenly feeling stuffy or cold due to the large temperature difference between the fresh air supply temperature and the air-conditioning command temperature when the air-conditioning is initially started, thereby improving the temperature comfort of the "first breath" of fresh air.

[0155] Specifically, the system first obtains the inlet temperature of the gas at the air inlet, which is an important basis for evaluating the comfort level of the current air-conditioning system's inlet temperature. Next, the system calculates the first difference between the inlet temperature and the target temperature value indicated by the air-conditioning start instruction. The target temperature value represented by the air-conditioning start instruction is usually set by the user through the vehicle interface or the remote control terminal. The system compares the calculated first difference with the preset temperature difference. The preset temperature difference is a threshold used to determine whether the current inlet temperature is close to or reaches the air-conditioning effect expected by the user. If the absolute value of the first difference is greater than the preset temperature difference, it means that the temperature comfort effect of the current air-conditioning system is not close to or reaches the user's expectations, then it is necessary to further determine whether the exhaust temperature at this time is higher than the target temperature value or lower than the target temperature value before it can be determined whether to enter the initial air cooling mode or the initial air heating mode.

[0156] If the first difference is a positive value, it means that the inlet air temperature is greater than the target temperature value. If the inlet air is not processed, the "first breath" of air delivered after starting the normal air supply mode of the air conditioner will be hotter. In this case, it is necessary to control the first control damper to close and open the second control damper to control the vehicle air conditioning system to enter the initial air cooling mode.

[0157] Specifically, once it is determined that the first difference is a positive value, the vehicle air-conditioning system is controlled to enter the initial air cooling mode, that is, the first control damper is closed, the second control damper is opened, and the compressor, condenser, and evaporator are started, the vehicle's air conditioning is turned on for cooling, the internal and external circulation dampers are switched to the external circulation intake, and the blower runs at the maximum gear to suck in the outdoor ambient air of the target vehicle for cooling.

[0158] As an optional embodiment, in response to the first difference being a negative value, the first control damper is controlled to be opened and the second control damper is controlled to be closed, and the vehicle air conditioning system is controlled to enter the primary air heating mode.

[0159] If the first difference is a negative value, it means that the intake air temperature is lower than the target temperature. If the intake air is not processed, the "first breath" of air delivered after starting the normal air supply mode of the air conditioner will be cooler. In this case, it is necessary to control the first control damper to open and the second control damper to close, and control the vehicle air conditioning system to enter the initial air heating mode.

[0160] Specifically, once it is determined that the first difference is a negative value, the vehicle air-conditioning system is controlled to enter the primary air heating mode, that is, the first control damper is opened, the second control damper is closed, the heating component is started, and the vehicle's air conditioning is turned on for heating; the internal and external circulation dampers are switched to the external circulation intake, and the blower runs at the maximum gear to suck in the outdoor ambient air of the target vehicle and then cool it down.

[0161] As an optional embodiment, the method also includes: continuously monitoring the exhaust air temperature of the exhaust outlet, calculating the second difference between the exhaust air temperature and the target temperature value; in response to the absolute value of the second difference being not greater than a preset temperature difference, controlling the vehicle air-conditioning system to exit the primary air cooling mode or the primary air heating mode.

[0162] In this embodiment, the vehicle air conditioning system not only controls the start of the initial air cooling or initial air heating mode according to the shutdown time and the inlet air temperature, but also determines when to exit these modes by continuously monitoring the exhaust air temperature at the exhaust vent and comparing it with the target temperature value. This strategy is designed to ensure that the temperature inside the vehicle can be stably maintained within the comfortable range set by the user while avoiding unnecessary energy consumption.

[0163] Specifically, if the absolute value of the second difference is not greater than the preset temperature difference, the system believes that the temperature of the air in the car has approached or reached the target temperature after processing, and there is no need to continue to run the initial air cooling or initial air heating mode. When the exit condition is met, the system controls the shutdown of the corresponding cooling or heating components, and adjusts the working state of the damper components to ensure that the air in the car can continue to circulate but no longer undergoes significant heating or cooling. The system may enter standby mode or adjust to other appropriate operating modes based on other conditions (such as occupant activity, changes in the external environment, etc.).

[0164] It should be noted that the system compares the absolute value of the calculated second difference with the preset temperature difference. The preset temperature difference is a threshold value used to determine whether the current exhaust air temperature deviates too much from the user's expected air conditioning effect. If the absolute value of the second temperature difference is greater than the preset difference, the system continues to adjust the initial air temperature.

[0165] As an optional embodiment, after controlling the vehicle air conditioning system to exit the primary air cooling mode or the primary air heating mode, the method further includes: responding to a start instruction to enter a normal air supply mode.

[0166] refer to Figure 8 , which is a structural diagram of the vehicle air conditioning system in normal air supply mode.

[0167] Specifically, if the second difference is not greater than the preset temperature difference, it means that the current supply air temperature after processing inside the air-conditioning box is not much different from the air-conditioning effect expected by the user, and the system can respond to the air-conditioning start instruction to enter the normal air supply mode.

[0168] In this embodiment, after the vehicle air-conditioning system completes the initial air cooling or initial air heating task, that is, the temperature in the vehicle has approached or reached the comfort range set by the user, it will not immediately enter the standby state or shut down completely, but can further respond to the user's start command (or wait until responding to the user's next start command). The system will quickly adjust to the normal air supply mode and continue to provide suitable airflow and temperature environment for the vehicle.

[0169] As an optional embodiment, the control damper assembly also includes a face damper, a foot damper and a defrost damper; in response to a start command, entering a normal air supply mode, including: in response to the start command to instruct the vehicle air conditioning system to enter an air supply cooling mode, controlling the closing of the first control damper, closing the exhaust damper and opening the second control damper, sucking in the air in the target vehicle, passing through the filter element and the evaporator in sequence, and then passing through the face damper and / or the foot damper and / or the defrost damper to enter the cabin of the target vehicle.

[0170] As an optional embodiment, after responding to the start-up instruction instructing the vehicle air conditioning system to enter the air supply cooling mode, the method further includes: controlling to turn off the heating component.

[0171] Specifically, once it is determined that the vehicle air conditioning system enters the air supply cooling mode, it is necessary to control the heating component to be turned off.

[0172] Specific operations may include:

[0173] Control and close the exhaust damper corresponding to the exhaust vent: stop discharging the treated air out of the vehicle to reduce energy loss.

[0174] Close the first control damper (when only the air conditioning cooling function is required): If the first control damper is previously used to guide air to flow through the heating component, close it at this time to disconnect the path.

[0175] Open the second control damper: Opening the second control damper can increase the flow width of fresh air inside the air-conditioning box.

[0176] At this time, as an optional embodiment, the internal and external circulation dampers can be controlled to switch to the external circulation mode, allowing more fresh air to enter the air conditioning box for circulation. The ratio of the internal circulation mode or the external circulation mode can also be adjusted by controlling the opening of the internal and external circulation dampers. For example, if the ratio of the internal and external circulation dampers to the internal circulation air inlet is 30% and the ratio to the external circulation air inlet is 70%, then 30% of the air inhaled into the air conditioning box comes from the vehicle compartment and 70% comes from the external environment of the target vehicle.

[0177] Adjustment of the air flow path: After the air in the vehicle is sucked in, it passes through the filter element and the evaporator in sequence for cleaning and cooling, then passes through the air outlet area corresponding to the second control damper, and selectively enters the cabin of the target vehicle through the face damper, foot damper and / or defrost damper as needed.

[0178] As an optional embodiment, responding to the start instruction and entering the normal air supply mode further includes:

[0179] In response to the start command instructing the vehicle air conditioning system to enter the air supply and heating mode, the first control damper is controlled to open, the exhaust damper is closed, and the second control damper is closed. After the air inside the target vehicle is sucked in, it passes through the filter element, the evaporator and the heating component in sequence, and then passes through the face-blowing damper and / or the foot-blowing damper and / or the defrost damper and enters the cabin of the target vehicle.

[0180] As an optional embodiment, after responding to the start-up instruction instructing the vehicle air conditioning system to enter the air supply and heating mode, the method further includes: controlling to turn on the heating component.

[0181] Specifically, once it is determined that the vehicle air conditioning system enters the air supply and heating mode, it is necessary to control the heating component to be turned on for heating.

[0182] Specific operations may include:

[0183] Control and close the exhaust damper corresponding to the exhaust vent: stop discharging the treated air out of the vehicle to reduce energy loss.

[0184] Open the first control damper (when only the air conditioning heating function is required): If the first control damper has not been used to guide air to flow through the heating component, it is now opened to open the path.

[0185] Close the second control damper: to ensure that all air is introduced into the heating component.

[0186] As can be seen from the above content, when there is no need to clean and deodorize the internal components of the air conditioner, the embodiment of the present invention can also realize intelligent adjustment of the working state of the air conditioning system by real-time monitoring of the air inlet temperature and the exhaust air temperature and comparing them with the preset command value, so as to pre-adjust the initial air supply temperature of the air conditioner to the most suitable. This feedback-based control strategy can ensure that the air conditioning system can provide stable and efficient performance in different environments, while reducing unnecessary energy consumption.

[0187] It should be noted that in actual operation, the system may also need to consider other factors, such as the ambient temperature, the temperature distribution in the car, the specific temperature set by the user, etc., to comprehensively determine whether the heating component needs to be turned on and the degree to which it should be turned on. In addition, if the system detects that the concentration of odorous gas in the passenger compartment, the filter element in the air-conditioning box, the evaporator or the heating component is too high, even if the shutdown time is lower than the preset threshold, additional deodorization measures may be required.

[0188] refer to Figure 8 , which is a schematic diagram of the overall flow of the control method for the vehicle air-conditioning system provided in an embodiment of the present invention.

[0197] Step S809, calculating the first temperature difference, that is, the inlet air temperature difference (inlet air temperature difference = inlet air temperature - air conditioning command value).

[0198] Step S810, determining whether the absolute value of the first temperature difference is greater than a preset threshold value, if the determination result is "yes", proceed to step S811; if the determination result is "no", proceed to step S822.

[0199] Step S811, determine whether the first temperature difference is a positive value, if the determination result is "yes", proceed to step S812; if the determination result is "no", proceed to step S818.

[0200] Step S812, enter the initial air cooling mode: ① Keep the mode damper closed and the exhaust damper open; ② Adjust the second control damper to the open state and the first control damper to the closed state; ③ Start the compressor, condenser, and evaporator, and turn on the air conditioner for cooling; ④ Switch to external circulation air intake, and the blower runs at the maximum gear.

[0209] Step S821, exit the initial air heating mode.

[0210] Step S822, in response to receiving the air-conditioning start instruction, directly start the air-conditioning to supply air normally.

[0211] In summary, the control method of the present invention can make the first breath of fresh air delivered by the car air conditioner cleaner, odor-free, and at a more comfortable temperature by controlling the air-conditioning box damper without adding too many additional auxiliary equipment and making the HVAC assembly structure complicated and bloated.

[0212] It should be noted that the difference between the deep deodorization mode and the quick deodorization mode is that the deep deodorization mode cleans and deodorizes all components inside the air-conditioning box after the vehicle air-conditioning system is started, so that the fresh air initially delivered by the air-conditioning is as clean, odor-free, and fresher as possible. In the quick deodorization mode, the components inside the air-conditioning box are selectively cleaned and deodorized (that is, the heating components are not cleaned and deodorized). In the quick deodorization mode, compared with the comprehensive deodorization mode, it can ensure that the vehicle air-conditioning system can clean and deodorize the internal components more quickly. Since the heating components do not need to be cleaned and deodorized in the quick deodorization mode, the quick deodorization mode is more suitable for air-conditioning use scenarios that only require cooling, while the comprehensive deodorization mode is more suitable for air-conditioning use scenarios that require heating, the air-conditioning is shut down for a long time, or the air quality in the vehicle stagnant environment is poor.
