[0002] With the rapid popularization of new energy vehicles, users' expectations for their driving and riding experience are constantly increasing, among which cabin temperature comfort has become one of the key indicators for measuring product competitiveness. The cooling system of new energy vehicles, as the core of the vehicle's thermal management, directly affects driving and riding comfort. However, in hot weather, the temperature inside the cabin rises sharply after the vehicle has been exposed to the sun, reaching 60℃ or even higher, and the surfaces of components such as the steering wheel and seats become extremely hot to the touch, seriously affecting the user experience.

[0003] In related technologies, vehicle refrigeration systems rely on a single compressor drive, with a relatively fixed refrigerant flow rate and limited heat exchange efficiency. This makes it difficult to quickly reduce cabin temperatures above 60°C to a comfortable range after exposure to direct sunlight, often requiring users to endure 10 to 15 minutes of stuffy waiting.

[0012] According to another aspect of this application, a computer device is provided, the computer device including a processor and a memory, the memory storing at least one instruction, at least one program, code set or instruction set, the at least one instruction, the at least one program, the code set or instruction set being loaded and executed by the processor to implement the vehicle temperature control method as described above.

[0013] According to another aspect of this application, a computer-readable storage medium is provided, wherein at least one instruction, at least one program, code set, or instruction set is stored therein, wherein the at least one instruction, the at least one program, the code set, or the instruction set is loaded and executed by a processor to implement the vehicle temperature control method as described above.

[0015] The beneficial effects of the technical solution provided in this application include at least the following: By coordinating the control of the refrigeration and air supply systems, rapid and precise cabin temperature regulation is achieved. Utilizing the pressure difference naturally formed between the condenser and evaporator during refrigeration startup as a trigger condition, the siphon valve automatically activates when the pressure difference exceeds a threshold. Operating on the siphon principle, the siphon valve significantly increases the refrigerant flow rate within the evaporator, thereby accelerating the heat exchange rate between the refrigerant and the hot air inside the vehicle. This mechanism improves cooling efficiency from the source of the refrigeration cycle, allowing the cabin to cool from a high temperature to a comfortable temperature range in a shorter time, effectively reducing user waiting time and achieving rapid cooling. Simultaneously, temperature sensors continuously monitor the temperature of specific areas of interest within the cabin. When an excessively high temperature is detected at a target location, the system automatically adjusts the airflow direction and speed of the corresponding air vents. This ensures that cool air is delivered directly and concentratedly to the hottest areas requiring cooling, such as the steering wheel or seats that have become excessively hot after being exposed to direct sunlight. This precise airflow not only quickly reduces the surface temperature of components directly in contact with the user, improving tactile comfort, but also promotes a more even temperature drop across the cabin, reducing localized overheating or overcooling and achieving precise temperature control. By triggering siphon acceleration through pressure difference to improve basic cooling efficiency, and combining it with temperature feedback to achieve adaptive directional adjustment of the air outlet, the two work together to solve the pain points of slow cooling speed and excessively high local temperature after the vehicle has been exposed to the sun, thereby significantly improving the overall driving and riding comfort experience of the user.

[0022] Figure 1 This is a schematic diagram of a vehicle air conditioning control system provided in an embodiment of this application. See also... Figure 1 The system includes: a control device 101, a cooling system 102, a temperature sensor 103, a pressure sensor 104, and a light intensity sensor 105. The temperature sensor 103, pressure sensor 104, light intensity sensor 105, and cooling system 102 are all electrically connected to the control device 101.

[0023] In this embodiment, the temperature sensor 103 includes at least one temperature sensor disposed inside and / or outside the vehicle cabin. For example, at least one temperature sensor may be disposed at the driver's seat, passenger seat, rear seat headrest, rear seat legrest, steering wheel, front windshield, rear windshield, and side window positions. The temperature sensor 103 is used to monitor the temperature of each location of interest in the vehicle and transmit the temperature data to the control device 101.

[0029] Figure 2 This is a schematic flowchart illustrating a vehicle temperature control method provided in an exemplary embodiment of this application. This method can be used as... Figure 1 The temperature control system of the vehicle shown is executed by a control device within the temperature control system. The method includes the following steps.

[0030] Step 210: In the case of refrigeration startup, monitor the refrigerant pressure difference between the condenser and evaporator of the refrigeration system using a pressure sensor, and monitor the temperature at at least one location of interest in the vehicle's cabin using a temperature sensor.

[0031] For example, this method can be applied to a vehicle's temperature control system, and the method is executed by a control device in the temperature control system.

[0032] For example, a pressure sensor is installed between the condenser and evaporator of the refrigeration system. The pressure sensor can measure the refrigerant pressure difference between the condenser and evaporator in the refrigeration system in real time. Optionally, the pressure sensor is installed on the refrigerant pipeline connecting the condenser outlet and the evaporator inlet, and its measuring probe is in direct contact with the refrigerant in the pipeline. It can continuously monitor the real-time pressure values ​​on the high-pressure side (condenser outlet) and the low-pressure side (evaporator inlet), and convert the pressure signal into an electrical signal through internal circuitry and transmit it to the control device.

[0033] For example, at least one temperature sensor is installed at at least one location of interest within the vehicle's cabin. The location of interest is the location where temperature needs to be monitored, and can be determined based on temperature monitoring requirements. For example, the location of interest may include at least one of the following: driver's seat, front passenger seat, rear seat headrest, rear seat legrest, and steering wheel position.

[0034] To achieve precise temperature zone monitoring and adaptive adjustment, high-precision temperature sensors are installed in several key areas of concern within the vehicle cabin. These sensors are specifically positioned in the driver's seat, passenger seat, and rear head and leg areas, while also monitoring the surface temperature of components such as the steering wheel and seats. The temperature sensors collect temperature data from each area in real time, once per second, and transmit the data to the control equipment. Based on the real-time temperature data, the control equipment analyzes the temperature differences in various locations within the cabin, thereby precisely controlling the angle and airflow speed of the corresponding air vents. For example, when the steering wheel area is detected to be too hot, the system instructs the corresponding air vent to aim at the steering wheel and increase the airflow speed to quickly cool it down.

[0035] For example, each location of interest may be provided with at least one temperature sensor. The temperature of a location of interest may be the average value of the temperature measured by the at least one temperature sensor corresponding to that location of interest, or the temperature of a location of interest may be the maximum value of the temperature measured by the at least one temperature sensor corresponding to that location of interest.

[0036] For example, this method can be used to rapidly cool the interior of a vehicle when the interior temperature is high. For instance, it can be used to rapidly cool the interior of a vehicle after it has been exposed to direct sunlight. The control device can use the method provided in this embodiment to monitor pressure difference and temperature for a first preset time after the cooling system starts. Monitoring stops after a longer cooling start time. Specifically, within the first preset time after the cooling system starts, the pressure difference of the refrigerant between the condenser and evaporator of the cooling system is monitored by a pressure sensor, and the temperature of at least one location of interest within the vehicle's cabin is monitored by a temperature sensor. If the pressure difference or temperature meets preset conditions, steps 220 and / or 230 are executed.

[0037] Alternatively, the control device can detect the vehicle interior temperature after cooling is started (e.g., receive the temperature reported by at least one temperature sensor and calculate the average value to obtain the vehicle interior temperature). If the vehicle interior temperature is higher than a preset value, the method provided in this embodiment is used to monitor the pressure difference and temperature; if the vehicle interior temperature is lower, there is no need to monitor the pressure difference and temperature. That is, after cooling is started, the vehicle interior temperature is detected. If the vehicle interior temperature is higher than a preset value, the pressure difference of the refrigerant between the condenser and evaporator of the cooling system is monitored by a pressure sensor, and the temperature of at least one location of interest in the vehicle's cabin is monitored by a temperature sensor. If the pressure difference or temperature meets the preset conditions, steps 220 and / or 230 are executed.

[0038] Step 220: When the pressure difference is greater than the pressure difference threshold, activate the siphon valve located between the condenser and the evaporator; the siphon valve is used to increase the flow rate of refrigerant in the evaporator based on the siphon principle.

[0039] For example, a siphon valve is installed between the condenser and evaporator in the refrigeration system. In the refrigeration cycle pipeline, the siphon valve is installed in series on the pipeline between the condenser outlet and the evaporator inlet. Its two ends are directly connected to the condenser outlet and the evaporator inlet respectively via pipes, forming a channel that allows unidirectional refrigerant flow. The core function of the siphon valve is to significantly increase the refrigerant flow rate within the evaporator using the siphon principle. When the vehicle is exposed to direct sunlight and the cooling system is started, the condenser on the high-pressure side of the system has a relatively low temperature, while the evaporator on the low-pressure side has a higher temperature due to absorbing heat from the cabin, naturally creating a significant pressure difference between the two. When the pressure sensor detects that this pressure difference exceeds a pressure difference threshold (e.g., 0.5 MPa), the control device instructs the siphon valve to open. After the siphon valve opens, the liquid refrigerant on the high-pressure side will quickly flow to the evaporator on the low-pressure side under the combined drive of its own gravity and the pressure difference between the two sides. This process is similar to the siphon phenomenon, thus adding an extra and strong suction force to the conventional cycle driven by the compressor. This can increase the flow rate of the refrigerant in the evaporator pipeline by 30% to 50%, which greatly accelerates the speed at which the refrigerant evaporates and absorbs heat in the evaporator, thereby improving the instantaneous cooling power and cooling rate of the refrigeration system.

[0040] For example, when the pressure difference is less than the pressure difference threshold, the siphon valve is gradually closed.

[0041] Step 230: If the temperature at the target location in at least one location of interest is higher than the temperature threshold, adjust the target air outlet corresponding to the target location, control the air outlet direction to point towards the target location, and increase the air outlet speed.

[0042] The control system monitors the temperature of specific locations of interest within the cabin in real time using temperature sensors and compares it to preset temperature thresholds. When the control system detects that the temperature of a target location (such as the steering wheel or seat) exceeds the set temperature threshold (e.g., the steering wheel area exceeds 40°C), it immediately activates an adaptive adjustment mechanism. The control system adjusts the target air outlet corresponding to the target location, directing the airflow directly towards the overheated target location by controlling the rotation of the air outlet's guide vane. Simultaneously, it instructs to increase the airflow speed of the outlet (e.g., to 80% or higher of the rated speed). This concentrates and efficiently directs cool air to the surface of high-temperature components, accelerating their heat exchange process and achieving rapid, targeted cooling of the localized area. Once the temperature at the target location drops below a safe or comfortable range, the system gradually reduces the airflow speed and adjusts the guide vane angle to restore a balanced airflow state, thereby addressing localized overheating while optimizing energy consumption and overall comfort.

[0043] For example, different areas of concern can have their own temperature thresholds. For instance, the temperature threshold for the steering wheel area could be 40°C, while the temperature threshold for the rear seat leg area could be 50°C.

[0044] For example, a location of interest may correspond to at least one air outlet, and a target location may correspond to a target air outlet, which may include at least one air outlet. The air outlet corresponding to the location of interest may be preset; for example, an air outlet that can directly blow air onto the location of interest may be set as the air outlet corresponding to the location of interest.

[0045] For example, if the temperature at the target location is lower than the temperature threshold, the air outlet direction of the target air outlet is restored to its original position, and the air outlet speed is restored to its original speed.

[0046] In summary, the method provided in this application achieves rapid and precise cabin temperature regulation by coordinating the control of the refrigeration system and the air supply system. It utilizes the pressure difference naturally formed between the condenser and evaporator during refrigeration startup as a trigger condition; when the pressure difference exceeds a threshold, the siphon valve is automatically activated. The siphon valve operates based on the siphon principle, significantly increasing the refrigerant flow rate within the evaporator, thereby accelerating the heat exchange rate between the refrigerant and the hot air inside the vehicle. This mechanism improves refrigeration efficiency from the source of the refrigeration cycle, enabling the cabin to cool from a high temperature to a comfortable temperature range in a shorter time, effectively shortening the user's waiting time and achieving rapid cooling. Simultaneously, temperature sensors continuously monitor the temperature of specific locations of interest within the cabin. When a target location is detected to be too hot, the system automatically adjusts the airflow direction and speed of the corresponding air vents. This ensures that cool air is directly and concentratedly delivered to the hottest areas requiring cooling, such as the steering wheel or seat areas that have become excessively hot after being exposed to direct sunlight. By precisely delivering air, the system not only rapidly reduces the surface temperature of components in direct user contact, improving tactile comfort, but also promotes a more even temperature drop across the cabin, reducing localized overheating or overcooling and achieving precise temperature control. Pressure differential-triggered siphon acceleration enhances basic cooling efficiency, while temperature feedback enables adaptive directional adjustment of the air outlets. These two mechanisms work synergistically to address the pain points of slow cooling and excessively high localized temperatures after a vehicle has been exposed to direct sunlight, significantly improving the overall driving and riding comfort experience for users.

[0047] Figure 3 This is a schematic flowchart illustrating a vehicle temperature control method provided in an exemplary embodiment of this application. This method can be used as... Figure 1 The temperature control system of the vehicle shown is based on... Figure 2 In the illustrated embodiment, step 220 includes step 221.

[0048] Step 210: In the case of refrigeration startup, monitor the refrigerant pressure difference between the condenser and evaporator of the refrigeration system using a pressure sensor, and monitor the temperature at at least one location of interest in the vehicle's cabin using a temperature sensor.

[0049] For example, a siphon acceleration device, including a siphon valve and a pressure sensor, is added between the condenser and evaporator of the refrigeration system. When the vehicle is exposed to direct sunlight and the refrigeration is started, the condenser temperature is low, while the evaporator temperature is high, creating a pressure difference between them. When the pressure difference reaches a preset threshold (e.g., 0.5 MPa), the siphon valve automatically opens, using the siphon principle to increase the flow rate of the refrigerant in the evaporator by 30% - 50%, accelerating the heat exchange rate and rapidly reducing the surface temperature of the evaporator, thereby achieving rapid cooling.

[0050] Meanwhile, the intelligent control system on the control equipment dynamically adjusts the opening of the siphon valve and the operating frequency of the compressor according to the in-vehicle temperature and cooling demand, ensuring that the refrigerant circulation is always in a high-efficiency state, reducing energy consumption while rapidly cooling.

[0051] Step 221: When the pressure difference is greater than the pressure difference threshold, control the siphon valve to open at the first speed.

[0052] For example, the control device can also adjust the compressor frequency of the refrigeration system according to the actual temperature of the cabin and the target temperature of the refrigeration; when the actual temperature reaches the target temperature, it controls the siphon valve to close at a second speed; the second speed is less than the first speed.

[0053] For example, when the actual temperature is in a first temperature range, the compressor frequency of the refrigeration system is set to a first frequency; when the actual temperature is in a second temperature range, the compressor frequency of the refrigeration system is set to a second frequency; wherein, the second temperature range includes the target temperature, the highest temperature in the second temperature range is lower than the lowest temperature in the first temperature range, and the first frequency is higher than the second frequency.

[0054] When the pressure sensor detects that the refrigerant pressure difference between the condenser and evaporator exceeds a preset pressure difference threshold (e.g., 0.5 MPa), the intelligent control system controls the siphon valve to open rapidly at a first speed (a relatively fast speed). In the initial cooling startup phase, the pressure difference is utilized to quickly establish and accelerate refrigerant circulation through the siphon principle, thereby rapidly increasing the cooling speed. For example, when starting the cooling system after a vehicle has been exposed to direct sunlight, the pressure difference quickly reaches the threshold, and the siphon valve opens rapidly, increasing the refrigerant flow rate by 30%-50% in a short time, achieving rapid cooling. Simultaneously, the control system dynamically adjusts the compressor's operating frequency based on the actual temperature collected by the cabin temperature sensor and the user-set target temperature (e.g., 25°C), for example, initially increasing the frequency to 80%-90% to enhance cooling. Once the actual temperature reaches the target temperature, the system controls the siphon valve to gradually close at a second speed (a slower speed than the first speed). This slow shutdown helps the system smoothly transition from the "rapid shutdown" mode to the normal maintenance mode, avoiding drastic fluctuations in refrigerant circulation and temperature caused by the sudden closure of the siphon valve. This ensures a stable cabin temperature while achieving a balance between energy saving and comfort.

[0055] Step 230: If the temperature at the target location in at least one location of interest is higher than the temperature threshold, adjust the target air outlet corresponding to the target location, control the air outlet direction to point towards the target location, and increase the air outlet speed.

[0056] Optionally, at least one of the following is a focus position: driver's seat, front passenger seat, rear seat head position, rear seat leg position, and steering wheel position.

[0057] For example, temperature sensors (i.e., high-precision temperature sensors) can be integrated or installed near the aforementioned locations in a non-contact or contact manner. For instance, temperature sensors may be installed in areas of interest such as the inside of the steering wheel rim or wheel spokes, under the surface of the seat back or cushion, and on the A-pillars, B-pillars, or headliner facing the passenger's head, to collect the air temperature or surface temperature of the area in real time at a frequency of once per second.

[0058] To more comprehensively perceive the cabin's thermal environment and enhance comfort, temperature sensors can be placed in other areas of interest. For example, sensors can be installed on frequently touched surfaces such as the center console, door armrests, and rear center armrests to monitor areas that may become hot due to direct sunlight or material heat buildup. Furthermore, to optimize air circulation and avoid temperature dead zones, auxiliary monitoring points can be placed in footwells (such as under the front seats or near the rear floor vents), near the sunroof, or at the connection between the trunk and the front seats. The control system continuously receives temperature data reported by all temperature sensors. When the temperature at any point of interest (such as the door armrest) exceeds its set comfort threshold, the system can coordinate with the nearest air vent (such as the door panel vents) to adjust the airflow direction and increase the fan speed, providing targeted cooling to that area. Simultaneously, this data can also be used to more precisely control the airflow distribution of the dual-zone climate control or the seat ventilation / heating functions, achieving intelligent temperature control throughout the entire cabin without any blind spots.

[0059] Optionally, step 230 may include at least one of the following: (1) When the temperature detected by the first temperature sensor in the driver's seat is higher than the temperature threshold, adjust the first air outlet in the driver's seat, control the air outlet direction of the first air outlet to point to the driver's seat, and increase the air outlet speed of the first air outlet.

[0060] (2) When the second temperature sensor in the passenger seat detects that the temperature is higher than the temperature threshold, adjust the second air outlet in the passenger seat to control the air outlet direction to point to the passenger seat and increase the air outlet speed.

[0061] (3) When the third temperature sensor at the head of the rear seat detects that the temperature is higher than the temperature threshold, adjust the third air outlet at the head of the rear seat to control the air outlet direction to point to the head of the rear seat and increase the air outlet speed.

[0062] (4) When the fourth temperature sensor at the rear seat leg position detects that the temperature is higher than the temperature threshold, adjust the fourth air outlet at the rear seat leg position, control the air outlet direction of the fourth air outlet to point to the rear seat leg position, and increase the air outlet speed of the fourth air outlet.

[0063] (5) When the fifth temperature sensor at the steering wheel position detects that the temperature is higher than the temperature threshold, adjust the fifth air outlet at the steering wheel position to control the air outlet direction of the fifth air outlet to point towards the steering wheel position and increase the air outlet speed of the fifth air outlet.

[0064] The temperature thresholds for different attention positions can also be different. For example, the driver's seat corresponds to the first temperature threshold, the passenger seat corresponds to the second temperature threshold, the rear seat head position corresponds to the third temperature threshold, the rear seat leg position corresponds to the fourth temperature threshold, and the steering wheel position corresponds to the fifth temperature threshold.

[0065] For example, multiple high-precision temperature sensors can be installed in the cabin, such as those at the driver's seat, passenger seat, and rear head and leg positions, to monitor the temperature in each area in real time.

[0066] Based on temperature sensor data, the intelligent control system of the control equipment automatically adjusts the angle and speed of the air vent deflectors. For example, when the temperature in the steering wheel area is detected to be too high, the corresponding air vent deflector is adjusted to point towards the steering wheel, increasing the air speed and quickly reducing the surface temperature of the steering wheel. Similarly, for the seat area, the air vents are adjusted according to the temperature to quickly cool the seat surface. At the same time, the rear air vents are also independently adjusted according to the temperature in the rear seat area to ensure that rear passengers can also quickly feel cool.

[0067] As the cabin temperature gradually decreases, the intelligent control system gradually adjusts the air outlet angle and wind speed to maintain a uniform temperature distribution while avoiding excessive cooling that could lead to energy waste and human discomfort.

[0068] In an optional embodiment, the control device can also, during cooling startup, acquire a temperature distribution map of the cabin using an infrared thermal imager installed in the cabin; analyze the temperature distribution map using a pre-trained neural network model, identify the occupant area and cabin background, detect abnormal temperature areas in the cabin background, and output the center coordinates of the abnormal areas; if the temperature of the abnormal area is higher than a temperature threshold; calculate at least one direction vector from at least one air outlet to the abnormal area based on the center coordinates of the abnormal area and the position coordinates of at least one air outlet; convert the at least one direction vector into the pitch angle and yaw angle of the guide vane corresponding to the air outlet; and adjust the airflow direction of at least one air outlet according to the calculated pitch angle and yaw angle of the guide vane, so that the airflow is directed towards the abnormal area.

[0069] For example, after the cooling system is activated, the control equipment can acquire a temperature distribution map of the entire cabin using an infrared thermal imager pre-installed in the cabin. Infrared thermal imaging technology can perform non-contact imaging based on the infrared radiation of objects, forming a thermal distribution image reflecting temperature differences. Subsequently, a pre-trained neural network model is used to analyze the temperature distribution map. This model, trained on a large amount of data, can effectively identify different regions in the image, such as segmenting the image into occupant areas (e.g., the human body on the seat) and cabin background areas (e.g., the dashboard, center console, door trim panels, etc.). After identifying the cabin background, the model further detects whether there are any abnormal temperature areas, where the temperature exceeds a preset temperature threshold. Once an abnormal temperature area is detected, the model outputs the center coordinates of the abnormal area, providing a target location for subsequent directional adjustments.

[0070] Then, the control equipment performs calculations based on the center coordinates of the abnormal area and the position coordinates of at least one air vent inside the vehicle (the position coordinates of the air vents were pre-calibrated and stored in the control equipment during vehicle design). It calculates the direction vector from each air vent to the abnormal area. This vector, within the three-dimensional cockpit space, defines the direction and distance from the air vent to the target point.

[0071] Then, these directional vectors in three-dimensional space are converted into specific mechanical action parameters that the air conditioner vent guide vane can perform, namely the pitch angle (vertical swing angle) and yaw angle (left-right swing angle) of the guide vane. This ensures that the calculated angles enable the centerline of the airflow blowing from the vent to accurately point to the center of the abnormal area.

[0072] Finally, the control equipment drives the stepper motor or servo mechanism of the corresponding air outlet according to the calculated pitch and yaw angles of each air deflector, adjusting the orientation of the air deflector. In this way, the airflow from one or more air outlets is concentrated towards the identified abnormal temperature area. Directional airflow can quickly and forcibly cool localized overheated areas, improving cooling efficiency and avoiding discomfort caused by cold air blowing directly on the occupants, achieving intelligent and precise cabin thermal management based on infrared visual perception.

[0073] In another alternative embodiment, the control device may also monitor light intensity via a light intensity sensor installed on the window glass, and monitor glass temperature via a temperature sensor installed on the window glass; when the light intensity is higher than a light intensity threshold and the glass temperature is higher than a glass temperature threshold, the heat insulation function of the window glass is activated.

[0074] For example, when the light intensity is higher than the light intensity threshold and the glass temperature is higher than the glass temperature threshold, the control device sends a control command to the control unit of the vehicle window glass to reduce the light transmittance of the vehicle window glass; the vehicle window glass is electrochromic glass; and / or, when the light intensity is higher than the light intensity threshold and the glass temperature is higher than the glass temperature threshold, the sunshade of the vehicle window glass is deployed.

[0075] For example, the vehicle window glass may include at least one of the following: windshield, rear windshield, driver's side window, passenger side window, rear side window, and roof glass.

[0076] The vehicle uses electrochromic glass or windows with a smart heat-insulating coating. When the vehicle is exposed to direct sunlight, sensors detect the increase in sunlight intensity and interior temperature, automatically triggering the glass's heat-insulating function. For example, electrochromic glass changes its light transmittance, and the heat-insulating coating enhances the heat insulation effect, effectively blocking external heat from entering the cabin, reducing the heat absorbed by interior components, and lowering their surface temperature.

[0077] Meanwhile, in conjunction with the vehicle's windows, the sunshades on the roof and side windows are also linked to the cooling system. When high temperatures and strong sunlight are detected, the sunshades automatically deploy to further reduce direct sunlight and slow the rate at which the interior temperature rises. The degree of sunshade deployment can be intelligently adjusted according to the angle of sunlight and the temperature distribution inside the vehicle, ensuring effective heat insulation without affecting interior lighting and visibility.

[0078] For example, the intelligent control system monitors sunlight intensity and window temperature using sensors, and triggers the window's heat insulation function when sunlight intensity exceeds a set threshold (e.g., 8000 lux) and the glass surface temperature exceeds 45°C. For electrochromic glass, it sends instructions to its control unit to reduce light transmittance; for glass with an intelligent heat-insulating coating, it enhances its heat insulation performance. Simultaneously, it automatically deploys the sun visor to further reduce direct sunlight when high temperatures and strong light are detected.

[0079] For example, when the vehicle is parked, the intelligent control system continuously monitors relevant sensor data. A light intensity sensor mounted on the window glass monitors the intensity of sunlight hitting the glass in real time, while a temperature sensor also mounted on the window glass monitors the real-time temperature of the glass surface. The system presets a light intensity threshold (e.g., 8000 lux) and a glass temperature threshold (e.g., 45°C). When the current light intensity is detected to be higher than this threshold, and the surface temperature of the window glass is also detected to be higher than this threshold, the intelligent control system determines that the vehicle is under intense sunlight and the window glass has become the main heat source, and then activates the window glass's heat insulation function. For windows using electrochromic glass, the control system sends a specific control command to the window glass's control unit. This command drives the electrochromic glass to rapidly change its optical state, significantly reducing the light transmittance from 70%-80% in its normal state to 30%-40%, thereby effectively blocking infrared rays and most visible light from sunlight and reducing heat transfer into the cabin. And / or, the system will coordinate with the corresponding sunshades (such as side window sunshades, windshield sunshades, and roof sunshades) to automatically deploy, further blocking direct sunlight from reaching the glass through physical barriers. For example, these operations are linked and can occur simultaneously. With the heat insulation function activated, heat radiation entering the cabin is reduced, lowering the interior temperature. The intelligent control system continuously monitors changes in light intensity and glass temperature. When light intensity decreases or the glass temperature drops below a threshold, the system will gradually restore the light transmittance of the window glass or retract the sunshades according to a preset strategy to achieve a balance between energy saving and comfort.

[0080] Optionally, when the vehicle is in motion, the control device can monitor the light intensity through light intensity sensors installed on the side windows and / or roof windows, and monitor the glass temperature through temperature sensors installed on the side windows and / or roof windows; if the light intensity is higher than the light intensity threshold and the glass temperature is higher than the glass temperature threshold, the heat insulation function of the side windows and / or roof windows can be activated.

[0081] In summary, the method provided in this application achieves rapid and precise cabin temperature regulation by coordinating the control of the refrigeration system and the air supply system. It utilizes the pressure difference naturally formed between the condenser and evaporator during refrigeration startup as a trigger condition; when the pressure difference exceeds a threshold, the siphon valve is automatically activated. The siphon valve operates based on the siphon principle, significantly increasing the refrigerant flow rate within the evaporator, thereby accelerating the heat exchange rate between the refrigerant and the hot air inside the vehicle. This mechanism improves refrigeration efficiency from the source of the refrigeration cycle, enabling the cabin to cool from a high temperature to a comfortable temperature range in a shorter time, effectively shortening the user's waiting time and achieving rapid cooling. Simultaneously, temperature sensors continuously monitor the temperature of specific locations of interest within the cabin. When a target location is detected to be too hot, the system automatically adjusts the airflow direction and speed of the corresponding air vents. This ensures that cool air is directly and concentratedly delivered to the hottest areas requiring cooling, such as the steering wheel or seat areas that have become excessively hot after being exposed to direct sunlight. By precisely delivering air, the system not only rapidly reduces the surface temperature of components in direct user contact, improving tactile comfort, but also promotes a more even temperature drop across the cabin, reducing localized overheating or overcooling and achieving precise temperature control. Pressure differential-triggered siphon acceleration enhances basic cooling efficiency, while temperature feedback enables adaptive directional adjustment of the air outlets. These two mechanisms work synergistically to address the pain points of slow cooling and excessively high localized temperatures after a vehicle has been exposed to direct sunlight, significantly improving the overall driving and riding comfort experience for users.

[0082] The method provided in this application utilizes the siphon principle to accelerate refrigerant circulation, thereby increasing the cooling speed by more than 50% compared to traditional methods. It can reduce the cabin temperature from high temperature to a comfortable range (25℃±2℃) within 3-5 minutes, significantly shortening the user's waiting time.

[0083] The method provided in this application embodiment can accurately cool the vehicle based on the temperature differences in different areas of the cabin through adaptive adjustment of the air outlet, making the temperature distribution in the cabin more uniform and controlling the temperature difference within 2°C. This effectively solves the problem of local overheating, especially by quickly reducing the surface temperature of components such as the steering wheel and seats, thereby improving the user's tactile comfort.

[0084] The method provided in this application embodiment dynamically adjusts the siphon valve and compressor according to the cooling demand of the intelligent control system. At the same time, the window glass is linked to heat insulation to reduce the air conditioning cooling load. Compared with the traditional air conditioning cooling method, energy consumption is reduced by 15%-20%, which is conducive to improving the driving range of new energy vehicles.

[0085] The method provided in this application comprehensively solves problems such as high cabin temperature, scalding hot parts, and uneven cooling after a vehicle has been exposed to the sun, providing users with a more comfortable and convenient driving environment and enhancing the market competitiveness of new energy vehicles.

[0086] The following is an embodiment of the vehicle temperature control method provided in this application.

[0087] (I) System Initialization When the vehicle starts, the intelligent control system performs self-checks on various sensors (temperature sensor, pressure sensor, light intensity sensor, etc.), siphon valve, compressor, air outlet actuator, and window glass control unit to ensure normal system operation.

[0088] Read the air conditioning settings and window status information from when the vehicle was last turned off as an initial reference.

[0089] (II) Temperature monitoring and data acquisition Multiple high-precision temperature sensors inside the cabin collect temperature data from various areas at a frequency of 1 second, including the head and leg positions of the driver, front passenger, and rear passengers, as well as the surface temperature of the steering wheel and seats.

[0090] A sunlight intensity sensor monitors the intensity of external sunlight in real time, while a window glass temperature sensor monitors the surface temperature of the glass.

[0091] The pressure sensor monitors the refrigerant pressure difference between the condenser and the evaporator, and is used to control the opening and closing of the siphon valve.

[0092] (III) Siphon-type refrigerant accelerated circulation control When the vehicle is exposed to direct sunlight and the cooling system is activated, and the pressure sensor detects that the pressure difference between the condenser and the evaporator reaches 0.5 MPa, the intelligent control system sends an opening command to the siphon valve. The siphon valve opens quickly, using the siphon principle to accelerate the circulation of refrigerant in the evaporator.

[0093] Meanwhile, based on the in-vehicle temperature and cooling demand, the intelligent control system dynamically adjusts the compressor's operating frequency. In the initial stage of cooling, the compressor frequency is increased to 80%-90% of the rated frequency to accelerate the cooling speed; as the cabin temperature decreases, the compressor frequency is gradually reduced to 60%-70% to maintain the cooling effect while reducing energy consumption.

[0094] When the average temperature inside the cabin drops below 28°C, the intelligent control system gradually closes the siphon valve, restoring the refrigerant circulation to normal.

[0095] (iv) Adaptive adjustment of air conditioning vents The intelligent control system analyzes the temperature differences in different areas based on data collected by temperature sensors. When the temperature of the steering wheel area exceeds 40°C, it controls the corresponding air vent deflector to rotate 30°-45° towards the steering wheel and increases the wind speed to 80% of the rated wind speed, continuously blowing towards the steering wheel until its surface temperature drops below 35°C. Then, it gradually reduces the wind speed and adjusts the angle of the deflector.

[0096] For the seating area, if the seat surface temperature is detected to be too high, the corresponding air outlet deflector will be adjusted to point towards the seat, and the air speed will be dynamically adjusted between 60% and 100% of the rated air speed according to the temperature to cool the seat quickly.

[0097] The rear air vents are independently adjusted based on the temperature in the rear area. When the rear temperature is higher than the front temperature, the airflow speed of the rear air vents is increased, and the angle of the air deflectors is adjusted to ensure effective cooling for the rear passengers. As the cabin temperature decreases evenly, the airflow speed and air deflector angle of each vent gradually return to a normal, comfortable state.

[0098] (v) Integrated heat insulation control of vehicle window glass When the sunlight intensity sensor detects that the sunlight intensity exceeds a set threshold (such as 8000 lux) and the window glass temperature sensor detects that the glass surface temperature exceeds 45°C, the intelligent control system triggers the heat insulation function of the window glass.

[0099] For electrochromic glass, a command is sent to its control unit to rapidly reduce its light transmittance from the normal 70%-80% to 30%-40%, effectively blocking infrared and ultraviolet rays from sunlight and reducing heat entering the cabin.

[0100] For glass with a smart heat-insulating coating, the heat insulation performance of the coating is enhanced, increasing the heat insulation rate of the glass from the conventional 40%-50% to 70%-80%.
