Description

Air conditioning unit, control method, control device and vehicle Technical Field

[0001] This application relates to the field of intelligent vehicles, and more particularly, to an air conditioning unit, a control method, a control device, and a vehicle. Background Technology

[0002] With the widespread application of smart cars in daily life, users increasingly expect them to provide a more comfortable and intelligent experience. Against this backdrop, equipping vehicles with efficient air conditioning systems has become the first choice for most car owners.

[0003] Traditional vehicle air conditioning systems are relatively simple in design, mostly possessing only a single air supply function. This means that air within the air conditioning unit can only flow in one direction along a predetermined path: fresh air enters the cabin through the vents, and existing air is expelled through the pressure relief vents due to pressure balance. However, this single airflow circulation method cannot efficiently remove accumulated stale air or odors from the vehicle. This design flaw becomes particularly apparent when the vehicle is used for extended periods, directly impacting the user's breathing comfort and overall riding experience.

[0004] Therefore, optimizing the ventilation and exhaust functions of the air conditioning system to improve the air quality inside the vehicle has become an important issue that urgently needs to be addressed in the development of intelligent vehicles. Summary of the Invention

[0005] This application provides an air conditioning unit, control method, control device, and vehicle that can actively expel stale air from the cabin to the outside of the vehicle, ensuring that the air inside the vehicle is always fresh and clean, thereby creating a comfortable breathing environment for the driver and passengers.

[0006] In a first aspect, an air conditioning unit is provided, comprising: a first channel, a second channel, and a third channel; the first channel has a first air inlet and an air outlet at both ends, the first air inlet being connected to the outside of the cabin via an external circulation damper, and the air outlet including a first air outlet being connected to the inside of the cabin via a surface air damper; the second channel has a second air inlet at one end, the second air inlet being connected to the inside of the cabin via an internal circulation damper, and the other end of the second channel being connected to the first channel, such that the second channel and the first channel share the first air outlet; the second channel is connected to the third channel via an exhaust damper, and one end of the third channel has an exhaust outlet, the exhaust outlet being connected to the outside of the cabin.

[0007] In one possible implementation, the air outlet also includes a second air outlet, which is connected to the outside of the cabin via a defrost damper.

[0008] In one possible implementation, the air vents can be located at the rear of the vehicle (e.g., inside the trunk trim panel or rear bumper).

[0009] The air conditioning unit provided in this application integrates smoke extraction and air circulation functions, which can expel bad air from the cabin to the outside of the vehicle while ensuring that the air inside the vehicle is always fresh and clean, thereby creating a comfortable breathing environment for the driver and passengers.

[0010] In conjunction with the first aspect, in some implementations of the first aspect, a shared blower is provided in the first channel and the second channel, the blower being used to deliver air from outside the cabin to the first channel and / or to deliver air from inside the cabin to the second channel.

[0011] In this embodiment of the application, the internal structure of the air conditioning unit can be simplified by sharing a blower, thereby reducing the installation cost of the air conditioning unit.

[0012] In conjunction with the first aspect, in some implementations of the first aspect, a shared air purification device is also provided in the first channel and the second channel, the air purification device being used to purify the air from the first air inlet and the second air inlet.

[0013] In this embodiment, the use of an air purification device ensures that the air inside the vehicle remains fresh and pure, creating a comfortable breathing environment for the driver and passengers. Furthermore, the shared air purification device design integrates the air purification function with the overall air conditioning system, simplifying the internal structure of the air conditioning unit and reducing the number of redundant components. This optimized design not only effectively reduces the manufacturing and installation costs of the air conditioning unit but also reduces the overall vehicle weight.

[0014] In conjunction with the first aspect, in some implementations of the first aspect, the air purification device includes an air conditioning filter, and a shared evaporator and a warm air core are also provided in the first channel and the second channel. The evaporator is used to cool the air passing through the air conditioning filter, and the warm air core is used to heat the air passing through the evaporator.

[0015] In one possible implementation, a temperature damper can be provided between the evaporator and the heating core to regulate the airflow entering the heating core.

[0016] In conjunction with the first aspect, in some implementations of the first aspect, the exhaust damper is disposed between the blower and the air purification device; when the exhaust damper is in the open state, the second channel is connected to the third channel, and air from the second air inlet is discharged from the exhaust port; when the exhaust damper is in the closed state, the second channel is not connected to the third channel, and air from the second air inlet is purified by the air purification device and discharged from the first air outlet.

[0017] In this embodiment, the connection between the second and third channels can be controlled by the exhaust damper. When the exhaust damper is open, pollutants in the cabin can be quickly discharged through the exhaust vent. When the air purification device includes an air conditioning filter, the exhaust damper is positioned before the air conditioning filter to avoid wasting the lifespan of the air conditioning filter, meaning that exhaust gas can be discharged directly outside the vehicle without passing through the air conditioning filter. When the exhaust damper is closed, residual pollutants in the cabin can be purified by the air purification device, thereby quickly removing odors from the cabin.

[0018] In conjunction with the first aspect, in some implementations of the first aspect, a smoke exhaust port is provided at the other end of the third channel, the smoke exhaust port is connected to the cabin, and a smoke exhaust fan and a smoke exhaust damper are sequentially arranged in the third channel, the smoke exhaust damper being used to open or block the third channel.

[0019] In conjunction with the first aspect, in some implementations of the first aspect, when the exhaust fan and the exhaust damper are open and the exhaust damper is closed, the air from the exhaust port passes through the third channel and is then discharged from the exhaust port.

[0020] In this embodiment, under conditions of high temperature or excessively high pollutant concentration in the cabin, the vehicle can control the opening of the exhaust fan and exhaust damper, and control the closing of the exhaust damper, allowing the gas in the cabin to be quickly discharged through the exhaust vent. In this way, users do not need to open the windows to expel unpleasant gases from the cabin after getting in the vehicle, thus improving the overall passenger experience.

[0021] In conjunction with the first aspect, in some implementations of the first aspect, a bypass ventilation door is provided in the second channel; when the bypass ventilation door is in the open state, the first channel and the second channel are connected, and the second channel and the first channel share the first air outlet.

The second channel shares the first air outlet with the first channel; the second channel is connected to the third channel through an exhaust damper, and one end of the third channel is provided with an exhaust port, which is connected to the outside of the cabin. The method includes: controlling the opening of the internal circulation damper, the external circulation damper, the face blowing damper, and the exhaust damper; wherein, when the exhaust damper is in the open state, the second channel is connected to the third channel, air from the second air inlet is discharged from the exhaust port, and air from the first air inlet is discharged from the face blowing damper.

[0023] In one possible implementation, before controlling the opening of the internal circulation damper, external circulation damper, face blowing damper and exhaust damper, the method further includes: acquiring a first temperature value inside the cabin and a second temperature value outside the cabin, and determining that the difference between the first temperature value and the second temperature value is greater than a first threshold.

[0024] In one possible implementation, a shared blower is provided in the first and second passages, the blower being used to deliver air from outside the cabin to the first passage and / or to deliver air from inside the cabin to the second passage.

[0025] In this embodiment, the vehicle can open the internal circulation damper, external circulation damper, face blowing damper, and exhaust damper. Unpleasant gases in the cabin can be quickly discharged through the exhaust vent, and fresh air from outside the vehicle can be continuously delivered to the cabin through the face blowing damper, thereby improving the overall riding experience for the user.

[0026] In conjunction with the second aspect, in some implementations of the second aspect, a shared air purification device is also provided in the first channel and the second channel. The air purification device is used to purify the air from the first air inlet and the second air inlet. The method further includes: controlling the exhaust damper to close so that the second channel is not connected to the third channel, and the air from the second air inlet is purified by the air purification device and then discharged from the first air outlet.

[0027] In one possible implementation, before controlling the exhaust damper to close, the method further includes: acquiring the contaminant concentration in a first area within the cabin and determining that the contaminant concentration is greater than or equal to a second threshold.

[0028] In one possible implementation, the air purification device includes an air conditioning filter, and a shared evaporator and a warm air core are also provided in the first and second channels. The evaporator is used to cool the air passing through the air conditioning filter, and the warm air core is used to heat the air passing through the evaporator.

[0029] In this embodiment of the application, when the exhaust damper is closed, the air inside and outside the cabin can be delivered to the cabin through the air purification device. During this process, the air purification device can effectively remove impurities such as dust, bacteria, and harmful gases from the air, thereby providing passengers with a fresh and clean breathing environment.

[0030] In conjunction with the second aspect, in some implementations of the second aspect, a smoke exhaust port is provided at the other end of the third channel, the smoke exhaust port is connected to the cabin, and a smoke exhaust fan and a smoke exhaust damper are sequentially arranged in the third channel. The smoke exhaust damper is used to open or block the third channel. The method further includes: controlling the smoke exhaust fan and the smoke exhaust damper to open, so that the air from the smoke exhaust port passes through the third channel and is discharged from the exhaust port.

[0031] In this embodiment of the application, by controlling the opening of the smoke exhaust fan and the smoke exhaust damper, the unpleasant gases in the cabin can be discharged more quickly, thereby further improving the user's overall riding experience.

[0032] Thirdly, a control device is provided, which is applied in an air conditioning unit. The air conditioning unit includes: a first channel, a second channel, and a third channel. The first channel has a first air inlet and an air outlet at both ends. The first air inlet is connected to the outside of the cabin via an external circulation damper.

[0033] In conjunction with the third aspect, in some implementations of the third aspect, a shared air purification device is also provided in the first channel and the second channel. The air purification device is used to purify the air from the first air inlet and the second air inlet. The processing unit is also used to control the exhaust damper to close so that the second channel is not connected to the third channel.

[0052] In the description of the embodiments of this application, unless otherwise stated, " / " means "or", for example, A / B can mean A or B; "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. In this application, "at least one" means one or more, and "more" means two or more. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or multiple items. For example, at least one of a, b, or c can represent: a, b, c, ab, ac, bc, or abc, where a, b, and c can be single or multiple.

[0053] The use of prefixes such as "first" and "second" in this application embodiment is solely for distinguishing different descriptive objects and does not limit the position, order, priority, quantity, or content of the described objects. The use of ordinal numbers and other prefixes to distinguish descriptive objects in this application embodiment does not constitute a limitation on the described objects. The description of the described objects is found in the claims or the context of the embodiments, and the use of such prefixes should not constitute unnecessary restrictions.

[0054] As described in the background section, traditional vehicle air conditioning systems are relatively simple in design, mostly possessing only a single air supply function. This means that air within the air conditioning unit can only flow unidirectionally along a predetermined path: fresh air enters the cabin through the air vents, and the air inside the vehicle is expelled through the pressure relief vents due to pressure balance. However, this single airflow circulation method cannot efficiently remove accumulated unpleasant air or odors from the vehicle. Especially when the vehicle is used for extended periods, the design flaws of the air conditioning unit become particularly apparent, directly impacting the user's breathing comfort and overall riding experience.

[0055] For example, under the scorching sun, most vehicles are exposed to direct sunlight in parking spaces. After prolonged exposure, the interior temperature becomes extremely high. When users try to use the vehicle, they can only do so by opening the windows to expel and lower the heat. This method is very slow because hot air does not circulate and escape quickly enough, making it difficult for the interior temperature to drop rapidly. Users are forced to endure the stuffy and uncomfortable feeling inside the car for an extended period. Furthermore, when users open the windows for ventilation, they may also be affected by external noise, dust, and poor air quality, which will also impact their driving experience.

[0056] For example, when some drivers or passengers smoke in the car, it creates a certain amount of smoke inside. To keep the air inside the car fresh, drivers or passengers usually choose to open the sunroof or windows to allow natural ventilation to expel the smoke. However, this method of ventilation is often not ideal when the vehicle is stationary, as the smoke tends to linger inside and is difficult to expel quickly. Furthermore, in inclement weather such as rain or snow, or in extreme environments such as extreme heat or cold, opening windows or sunroofs may allow cold air or rainwater to enter the car. This not only affects the comfort of the interior temperature but may also disrupt the dry environment inside the car, causing discomfort to the driver and passengers.

[0057] This application provides an air conditioning unit, a control method, a control device, and a vehicle that can actively expel stale air from the cabin to the outside of the vehicle, ensuring that the air inside the vehicle is always fresh and clean, thereby creating a comfortable breathing environment for the driver and passengers.

[0058] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0059] As shown in Figure 1, the vehicle 100 involved in this application may include multiple subsystems, such as a sensing system 120, a computing platform 130, and an air conditioning system 140. Optionally, the vehicle 100 may include more or fewer subsystems, and each subsystem may include one or more components. In addition, each subsystem and component of the vehicle 100 can be interconnected via wired or wireless means.

[0060] The perception system 120 may include several types of sensors for sensing information about the environment surrounding the vehicle 100. For example, the perception system 120 may include a positioning system, which may be a global positioning system (GPS), a BeiDou system, or another positioning system. The perception system 120 may include one or more of the following: an inertial measurement unit (IMU), lidar, millimeter-wave radar, ultrasonic radar, and a camera device.

[0061] Some or all of the functions of vehicle 100 can be controlled by computing platform 130. Computing platform 130 may include processors 131 to 13n (n being a positive integer). A processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a central processing unit (CPU), microprocessor, graphics processing unit (GPU) (which can be understood as a type of microprocessor), or digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. These logical relationships are fixed or reconfigurable. For example, the processor may be a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In reconfigurable hardware circuits, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement some or all of the functions of the aforementioned units. Furthermore, the processor can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), tensor processing unit (TPU), deep learning processing unit (DPU), etc. In addition, the computing platform 130 may also include a memory for storing instructions. Some or all of the processors 131 to 13n can call the instructions in the memory to implement the corresponding functions.

[0062] The computing platform 130 can control the functions of the vehicle 100 based on inputs received from various subsystems (e.g., the sensing system 120). In some embodiments, the computing platform 130 can be used to provide control over many aspects of the vehicle 100 and its subsystems.

[0063] The air conditioning system 140 is responsible for regulating the temperature, humidity, and air quality inside the vehicle to improve passenger comfort and driving experience.

[0064] Optionally, the above components are just an example. In actual applications, the components in each of the above modules may be added or deleted as needed.

[0065] The vehicle 100 in this application may include: road vehicles, water vehicles, air vehicles, industrial equipment, agricultural equipment, or entertainment equipment, etc. For example, vehicle 100 may be a means of transportation (such as commercial vehicles, passenger cars, motorcycles, flying cars, trains, etc.), industrial vehicles (such as forklifts, trailers, tractors, etc.), engineering vehicles (such as excavators, bulldozers, cranes, etc.), agricultural equipment (such as lawnmowers, harvesters, etc.), amusement equipment, toy vehicles, etc. The embodiments of this application do not specifically limit the type of vehicle.

[0066] The air conditioning unit provided in this application embodiment includes: a first channel, a second channel, and a third channel; the first channel has a first air inlet and an air outlet at both ends, the first air inlet is connected to the outside of the cabin through an external circulation damper, and the air outlet includes a first air outlet, which is connected to the inside of the cabin through a face-blowing damper; the second channel has a second air inlet at one end, which is connected to the inside of the cabin through an internal circulation damper, and the other end of the second channel is connected to the first channel, so that the second channel and the first channel share a first air outlet; the second channel is connected to the third channel through an exhaust damper, and one end of the third channel has an exhaust outlet, which is connected to the outside of the cabin.

[0067] Optionally, the air conditioning unit can be used in vehicle 100, and more preferably, the air conditioning unit is located in air conditioning system 140.

[0068] Optionally, the air outlet may also include a second air outlet, which is connected to the outside of the cabin via a defrost damper.

[0069] Optionally, a bypass ventilation door is provided in the second channel; when the bypass ventilation door is open, the first channel and the second channel are connected, and the second channel and the first channel share the first air outlet.

[0070] Optionally, a smoke exhaust port is provided at the other end of the third passage, which is connected to the cabin. A smoke exhaust fan and a smoke exhaust damper are sequentially installed in the third passage, which are used to open or close the third passage.

[0071] For example, when the exhaust fan and exhaust damper are open and the exhaust damper is closed, the air from the exhaust port passes through the third channel and is then discharged from the exhaust port.

[0072] It should be noted that the smoke exhaust fan, smoke exhaust damper, and third channel can form the smoke exhaust system of the air conditioning unit. When smoke or other visible particulate pollutants (such as smoking, smoke, etc.) are generated in the vehicle, the smoke exhaust system can quickly remove these smokes to ensure visibility and clean air inside the vehicle.

[0073] The air conditioning unit provided in this application integrates smoke extraction and air circulation functions, which can expel bad air from the cabin to the outside of the vehicle while ensuring that the air inside the vehicle is always fresh and clean, thereby creating a comfortable breathing environment for the driver and passengers.

[0074] In one possible implementation, a shared blower is provided in both the first and second passages. This blower is used to deliver air from outside the cabin to the first passage and / or to the second passage. This shared blower simplifies the internal structure of the air conditioning unit and reduces its installation costs.

[0075] In one possible implementation, a shared air purification device is also installed in both the first and second air intakes. This device purifies the air coming from both intakes. This ensures that the air inside the vehicle remains consistently fresh and clean, creating a comfortable breathing environment for the driver and passengers. Furthermore, the shared air purification device design integrates the air purification function with the overall air conditioning system, simplifying the internal structure and reducing the number of redundant components.

[0076] Optionally, the air purification device includes an air conditioning filter. Further optionally, the air purification device may also include a negative ion purifier, an ultraviolet sterilization module, and a photocatalytic sterilization module. That is, the air purification device can use ultraviolet light, plasma, or filters to disinfect and sterilize the air inside the vehicle, remove germs, viruses, and other harmful microorganisms from the air, and prevent the spread of infection.

[0077] Optionally, the first and second channels are also equipped with a shared evaporator and a warm air core. The evaporator is used to cool the air passing through the air conditioning filter, and the warm air core is used to heat the air passing through the evaporator.

[0078] Optionally, a temperature damper can be provided between the evaporator and the heating core to regulate the airflow entering the heating core.

[0079] In one possible implementation, the exhaust damper is positioned between the blower and the air purification device. When the exhaust damper is open, the second and third channels are connected, and air from the second air inlet is discharged from the exhaust outlet. When the exhaust damper is closed, the second and third channels are not connected, and air from the second air inlet is purified by the air purification device and then discharged from the first air outlet. Thus, when the air purification device includes an air conditioning filter, positioning the exhaust damper before the air conditioning filter avoids wasting the filter's lifespan, as exhaust gas is discharged directly outside the vehicle without passing through the filter. When the exhaust damper is closed, residual pollutants in the cabin can be purified by the air conditioning filter, thereby quickly removing odors from the cabin.

[0080] It should be noted that in this application, when the exhaust damper is in the open state, the second channel and the second channel are connected to form an exhaust system. The exhaust system can exhaust the polluted air in the vehicle to the outside. It can work in conjunction with the fresh air system to ensure air circulation in the vehicle, reduce the accumulation of exhaust gas, smoke and odors in the vehicle, and prevent air stagnation.

[0081] In one possible implementation, the internal structure of the air conditioning unit can be as shown in Figure 2.

[0082] Optionally, the air conditioning unit may also include more components. For example, the air conditioning unit may also include an air quality sensor module, a temperature control system, a control system, and other components. The air quality sensor module is used to detect air quality indicators inside the vehicle, including the concentration of harmful substances such as CO2 and PM2.5. The temperature control system can adjust the temperature inside the vehicle to a comfortable range set by the passengers, providing cooling and heating functions. The control system may include a controller for controlling the operation of the air conditioning unit, such as controlling the opening or closing of one or more dampers in the air conditioning unit. Other components may include a compressor and an electric air vent.

[0083] It should be noted that the internal structure of the air conditioning unit shown in Figure 2 is merely an illustrative example and does not constitute a limitation of this application. Those skilled in the art can add, reduce, or replace the components shown in Figure 2 according to actual needs.

[0084] Figure 3 is a schematic flowchart of an air purification method provided in an embodiment of this application. The execution subject of method 300 can be a controller, control system or vehicle of an air conditioning unit. Method 300 describes the working process of the air conditioning unit in any of the aforementioned implementations. Method 300 may include step S301.

[0085] S301 controls the opening of the internal circulation damper, external circulation damper, face blowing damper, and exhaust damper.

[0086] When the internal circulation damper is open, the air inside the cabin can enter the second channel under the action of the blower. When the external circulation damper is open, fresh air from outside the vehicle can enter the first channel. When the exhaust damper and the air blowing damper are open, the second channel is connected to the third channel. Air from the second air intake is discharged from the exhaust port, and air from the first air intake is discharged from the air blowing damper.

[0087] In one possible implementation, before step S301, method 300 further includes: obtaining a first temperature value inside the cabin and a second temperature value outside the cabin, then step S301 includes: if the difference between the first temperature value and the second temperature value is greater than or equal to a first threshold, controlling the opening of the internal circulation damper, the external circulation damper, the face blowing damper and the exhaust damper.

[0088] Optionally, one or more temperature sensors can be installed in key locations within the vehicle (e.g., in the center of the cabin, near the dashboard, or at the air conditioning vents) to monitor the air temperature inside the vehicle in real time, thereby obtaining a first temperature value. One or more temperature sensors can be installed at the front of the vehicle (e.g., inside the front bumper or below the rearview mirror) to monitor the outside air temperature in real time, thereby obtaining a second temperature value. Further optionally, the vehicle can obtain the second temperature value via a cloud server.

[0089] Optionally, acquiring a first temperature value inside the cabin and a second temperature value outside the cabin includes: acquiring the first and second temperature values ​​at a second travel time, provided that a first travel time has been acquired, wherein the second travel time is earlier than the first travel time. This allows the vehicle to quickly expel hot air from the cabin through the exhaust vents in advance, and allows fresh air from outside the vehicle to be continuously delivered into the cabin through the air vents in advance.

[0090] Optionally, the vehicle can obtain the user's first travel time through cloud data, or the user can set the first travel time in advance through a mobile application, and the vehicle can obtain the user's set first travel time from the mobile phone.

[0091] For example, the difference between the first travel time and the second travel time is a first preset value, such as 5 minutes.

[0092] For example, when the difference between the first temperature value and the second temperature value is greater than or equal to 10 degrees Celsius, the vehicle controls the opening of the internal circulation damper, external circulation damper, face blowing damper and exhaust damper.

[0093] In this embodiment, the vehicle can open the internal circulation damper, external circulation damper, face blowing damper, and exhaust damper. Unpleasant gases in the cabin can be quickly discharged through the exhaust vent, and fresh air from outside the vehicle can be continuously delivered to the cabin through the face blowing damper, thereby improving the overall riding experience for the user.

[0094] In one possible implementation, a shared air purification device is provided in the first and second channels of the air conditioning unit. After step S301, method 300 further includes: controlling the exhaust damper to close so that the second channel is not connected to the third channel, and the air from the second air inlet is purified by the air purification device and then discharged from the first air outlet.

[0095] In one possible implementation, before controlling the exhaust damper to close, method 300 further includes: obtaining the contaminant concentration in a first area within the cabin and determining that the contaminant concentration is greater than or equal to a second threshold.

[0096] For example, when the particulate matter concentration is greater than 100 micrograms per cubic meter, the exhaust damper should be closed.

[0097] Optionally, the air purification device includes an air conditioning filter. Further optionally, the air purification device may also include a negative ion purifier, an ultraviolet sterilization module, and a photocatalytic sterilization module. That is, the air purification device can use ultraviolet light, plasma, or filters to disinfect and sterilize the air inside the vehicle, remove germs, viruses, and other harmful microorganisms from the air, and prevent the spread of infection.

[0098] Optionally, the concentration of pollutants in the cabin can be detected by setting up a smoke sensor or a PM2.5 sensor. Further optionally, the concentration of pollutants may include at least one of the following: particulate matter concentration, CO concentration, CO2 concentration, or nitrogen oxide concentration.

[0099] Optionally, the first area can be the entire cabin area, or the first area can be a portion of the cabin.

[0100] In this embodiment of the application, when the exhaust damper is closed, the air inside and outside the cabin can be delivered to the cabin through the air purification device. During this process, the air purification device can effectively remove impurities such as dust, bacteria, and harmful gases from the air, thereby providing passengers with a fresh and clean breathing environment.

[0101] In one possible implementation, a smoke exhaust fan and a smoke exhaust damper are sequentially arranged in the third channel of the air conditioning unit. After step S301, method 300 further includes: controlling the smoke exhaust fan and the smoke exhaust damper to open, so that air from the smoke exhaust port passes through the third channel and is discharged from the exhaust port.

[0102] In this embodiment, the vehicle can control the opening of the exhaust fan and exhaust damper. This allows for the faster removal of unpleasant gases from the cabin, thereby further improving the overall passenger experience.

[0103] The working process of the air conditioning unit in various application scenarios is explained in detail below with reference to Figures 4 to 10.

[0104] Figure 4 is a schematic diagram of the operation of an air conditioning unit in a high-temperature scenario, according to an embodiment of this application.

[0105] As shown in Figure 4, when the cabin temperature is too high and hot air needs to be quickly expelled, the vehicle can operate the blower and control the opening of the internal circulation damper, external circulation damper, and exhaust damper. At this time, the hot air in the cabin can enter the second channel through the internal circulation damper, and under the action of the blower, it is exhausted outside the vehicle through the exhaust damper and vent. At the same time, fresh air from outside the vehicle enters the first channel through the external circulation damper. Under the action of the blower, the fresh air is purified by the air conditioning filter, and then passes through the evaporator and heater core for cooling and heating. Finally, the treated fresh air is sent into the cabin through the air vent.

[0106] Figure 5 is a schematic diagram of a process for rapid air exchange and cooling of an air conditioning unit in a high-temperature scenario provided by an embodiment of this application. Method 500 can be a detailed description of step S301 in method 300. Method 500 can include steps S501 to S503.

[0107] S501, obtains users' regular travel times.

[0108] Optionally, the vehicle can obtain the user's regular travel time through cloud data, or the user can set the travel time in advance through a mobile application, and the vehicle can obtain the user's set regular travel time from the mobile phone. The regular travel time can be the first travel time in method 300.

[0109] For example, the vehicle obtains the user's regular travel time through cloud data, which is 9:00 AM every day.

[0110] S502 determines whether the vehicle's ventilation function should be activated.

[0111] Specifically, the vehicle can detect the temperature inside and outside the cabin some time in advance (e.g., at the second travel time) based on the regular travel time. If the difference between the first temperature value inside the cabin and the second temperature value outside the cabin is greater than or equal to the first threshold, step S503 is performed; otherwise, the vehicle will not activate the ventilation function.

[0112] For example, the vehicle obtains the user's regular travel time from cloud data, which is 9:00 AM every day. At 8:50 AM, the vehicle detects the temperature inside the cabin and the temperature outside the cabin. When the temperature difference between the cabin and the outside cabin is greater than or equal to 10 degrees Celsius, step S503 is performed.

[0113] Optionally, one or more temperature sensors can be installed in key locations within the vehicle (e.g., in the center of the cabin, near the dashboard, or at the air vents) to monitor the air temperature inside the vehicle in real time. One or more temperature sensors can also be installed at the front of the vehicle (e.g., inside the front bumper or below the rearview mirror) to monitor the outside air temperature in real time. Further optionally, the vehicle can obtain the outside ambient temperature from a cloud server.

[0114] S503, activate the ventilation function.

[0115] Specifically, activating the ventilation function includes: turning on the air conditioner, setting the blower to maximum airflow, fully opening the internal circulation damper, opening the external circulation damper to a certain degree, fully opening the exhaust damper, setting the temperature damper to the cold end (i.e., the evaporator is working, and the heater filter is not working), closing the side ventilation damper, opening the face ventilation damper, closing the foot ventilation damper, closing the defrost damper, activating the seat ventilation function, and setting the electric air outlet to blow air onto the seat.

[0116] In this embodiment, in high-temperature scenarios, the vehicle can control the exhaust vent to open in advance, allowing the high-temperature gas in the cabin to be quickly discharged through the exhaust vent, while fresh air from outside the vehicle can be continuously delivered to the cabin through the air vent. In this way, users do not need to open the windows to drive away and reduce the heat inside the vehicle after getting in, thereby improving the overall riding experience of the user.

[0117] Figure 6 is a schematic diagram of another air conditioning unit for rapid air exchange and cooling in a high-temperature scenario provided by an embodiment of this application. Method 600 can be a detailed description of step S301 in method 300. Method 600 can include steps S601 to S603.

[0118] S601, detected that the air conditioning was turned on after the user got into the car.

[0119] Alternatively, the vehicle can determine whether a user has boarded the vehicle using door sensors, seat sensors, or the vehicle's infotainment system.

[0120] Optionally, the vehicle can turn on the air conditioning after detecting a first user input, which can be the user clicking an option on the center console or pressing a physical button, or the first input can be the user's voice input.

[0121] S602 detects the cabin temperature and ambient temperature to determine whether to activate the vehicle's ventilation and cooling function.

[0122] Specifically, if the difference between the first temperature value inside the cabin and the second temperature value outside the cabin is greater than or equal to the first threshold, step S603a is performed; otherwise, step S603b can be performed.

[0123] For example, when the difference between the first temperature value inside the cabin and the second temperature value outside the cabin is greater than or equal to 10 degrees Celsius, step S603a is performed.

[0124] Optionally, one or more temperature sensors can be installed in key locations within the vehicle (e.g., in the center of the cabin, near the dashboard, or at the air vents) to monitor the air temperature inside the vehicle in real time. One or more temperature sensors can also be installed at the front of the vehicle (e.g., inside the front bumper or below the rearview mirror) to monitor the outside air temperature in real time. Further optionally, the vehicle can obtain the outside ambient temperature from a cloud server.

[0125] S603a, activate the ventilation and cooling function.

[0126] Specifically, activating the ventilation and cooling function includes: controlling the air conditioner to turn on, setting the blower to maximum airflow, fully opening the internal circulation damper, setting the external circulation damper to a certain opening degree, fully opening the exhaust damper, setting the temperature damper to the cold end, closing the bypass ventilation damper, opening the face ventilation damper, closing the foot ventilation damper, closing the window ventilation damper, activating the seat ventilation function, and setting the electric air vents to blow air towards people.

[0127] S603b, ventilation and cooling function not activated.

[0128] Specifically, not activating the ventilation and cooling function includes: turning on the air conditioner, setting the blower to automatic airflow, fully opening the internal circulation damper, closing the external circulation damper, fully closing the exhaust damper, setting the temperature damper to the cold end, closing the bypass ventilation damper, opening the face ventilation damper, closing the foot ventilation damper, closing the window ventilation damper, activating the seat ventilation function, and setting the electric air vents to the swing mode.

[0129] In this embodiment, in a high-temperature scenario, after detecting that a user has entered the vehicle and turned on the air conditioning, the vehicle can open the exhaust vent, allowing the high-temperature gas in the cabin to be quickly discharged through the exhaust vent, while fresh air from outside the vehicle can be continuously delivered to the cabin through the air vent. In this way, the user does not need to open the window to drive away and reduce the heat inside the vehicle after entering, thereby improving the user's overall riding experience.

[0130] Figure 7 is a schematic diagram of an air conditioning unit in the odor removal scenario provided in an embodiment of this application.

[0131] As shown in Figure 7, when the vehicle detects that the concentration of pollutants in the cabin is too high, the vehicle can control the opening of the exhaust fan and exhaust damper, and control the closing of the exhaust damper. At this time, the smoke in the cabin can be transported to the third channel through the exhaust vent and then discharged outside the vehicle through the exhaust vent. At the same time, the vehicle can control the opening of the in-vehicle recirculation damper and open the external recirculation damper to a certain degree. At this time, the in-vehicle air and fresh air enter the vehicle and are purified by the air conditioning filter under the action of the blower. The purified air is then sent into the cabin through the air vent.

[0132] For example, as shown in Figure 8, the exhaust vent can be located at the front of the vehicle (e.g., below the hood or near the hood partition), the exhaust port can be located on the vehicle infotainment system and the front seats, and the air vent can be located at the rear of the vehicle (e.g., inside the trunk trim panel or the rear bumper). Pollutants in the cabin can enter the exhaust vent through each exhaust port and then be discharged from the air vent through the third channel.

[0133] Figure 9 is a flowchart illustrating an air conditioning unit in an odor removal scenario according to an embodiment of this application. Method 900 can be a specific description of the air purification scenario steps in method 300, and method 900 can include steps S901 to S903.

[0134] The S901 uses sensors to detect the concentration of pollutants inside the cabin.

[0135] Optionally, the concentration of pollutants in the cabin can be detected by a smoke sensor or a PM2.5 sensor.

[0136] Optionally, the concentration of pollutants may include at least one of the following: particulate matter concentration, CO concentration, CO2 concentration, or nitrogen oxide concentration.

[0137] Optionally, the pollutant concentration detected in step S901 may refer to the pollutant concentration of the entire cabin or the pollutant concentration of a portion of the cabin.

[0138] S902, determine whether the concentration of pollutants is greater than or equal to the second threshold.

[0139] Specifically, step S903 can be performed if the concentration of pollutants is greater than or equal to the second threshold; otherwise, no special treatment is required.

[0140] For example, when the particulate matter concentration is greater than 100 micrograms per cubic meter, step S903 can be performed.

[0141] S903, activate the odor removal function.

[0142] For example, activating the odor removal function includes: controlling the air conditioner to turn on, controlling the air purification system to turn on, controlling the exhaust fan to turn on, controlling the exhaust damper to close, fully opening the exhaust damper, and controlling the electric air outlet to avoid blowing air onto the user.

[0143] Optionally, when the vehicle detects that the concentration of pollutants in the entire cabin is greater than the second threshold, the vehicle can control all the electric air vents to avoid blowing air onto the user; when the vehicle detects that the concentration of pollutants in a certain area of ​​the cabin is greater than the second threshold, the vehicle can control the air vents in the corresponding area to avoid blowing air onto the user.

[0144] In this embodiment, when the concentration of pollutants in the cabin is too high, the vehicle can close the exhaust vent and open the smoke exhaust vent. In this way, the pollutants in the cabin can be quickly discharged through the air outlet. Moreover, the exhaust vent is located before the air conditioning filter, which can avoid wasting the life of the air conditioning filter. That is, the exhaust gas does not need to pass through the air conditioning filter and is directly discharged outside the vehicle. On the other hand, the pollutants remaining in the cabin can be purified by the air conditioning filter, thereby quickly removing the odor in the cabin.

[0145] Figure 10 is a flowchart of another air conditioning unit in the odor removal scenario provided by the embodiment of this application. Method 1000 can be a detailed description of the air purification scenario steps in method 300. Method 1000 can include steps S1001 to S1004.

[0146] S1001, detects that the concentration of pollutants in the cabin is greater than or equal to the second threshold.

[0147] Optionally, the concentration of pollutants in the cabin can be detected by a smoke sensor or a PM2.5 sensor.

[0148] Optionally, the concentration of pollutants may include at least one of the following: particulate matter concentration, CO concentration, CO2 concentration, or nitrogen oxide concentration.

[0149] For example, when the particulate matter concentration is greater than 100 micrograms per cubic meter, step S1002 can be performed.

[0150] S1002 prompts the user to select the area where odors will be removed.

[0151] For example, the vehicle can prompt the user to select the area to remove odors by displaying a prompt box on the central control screen, or the vehicle can prompt the user to select the area to remove odors by voice or by playing specific music. Accordingly, the user can click the corresponding control on the central control screen to select the area to remove odors, or the user can issue a voice command to the interactive assistant to select the area to remove odors.

[0152] S1003, It was detected that the user selected the first area.

[0153] For example, the first area can be a specific area in the cabin, such as the driver's area, the passenger's area, the left rear seat area, and the right rear seat area. Alternatively, the first area can be the front or rear area of ​​the cabin. Or, the first area can be the entire area of ​​the cabin.

[0154] Alternatively, no special action may be taken if the vehicle detects that the user has not made a selection.

[0155] It should be noted that this application does not limit the method of dividing the interior areas of the vehicle or the scope of the first area. Those skilled in the art can divide the cabin into areas according to actual needs.

[0156] S1004, removes odors from the first area.

[0157] Specifically, removing odors from the first area includes: turning on the air conditioner, turning on the air purification system, turning on the exhaust fan, closing the exhaust damper, fully opening the exhaust damper, and controlling the electric air outlet of the first area to avoid blowing air onto the user.

[0158] In this embodiment, when the concentration of pollutants in the cabin is too high, the vehicle can, based on the user's choice, close the exhaust vent and open the smoke vent. This allows pollutants in the corresponding area of ​​the cabin to be quickly expelled through the air vents, while residual pollutants in the cabin can be purified by the air conditioning filter, thus rapidly removing odors from the cabin.

[0159] Figures 11 to 13 are application scenario diagrams of the air conditioning unit opening and odor removal function provided in the embodiments of this application. Methods 300, 900 and 1000 can be applied to this application scenario.

[0160] As shown in Figure 11(a), the vehicle's central control screen displays: interface 1100 and function bar 1110. Interface 1100 includes user account login information 1101 (the vehicle is not currently logged into), Bluetooth icon 1102, Wi-Fi icon 1103, cellular network signal icon 1104, in-vehicle map application search box 1105, a card to switch to displaying all applications installed in the vehicle 1106, a card to switch to displaying the in-vehicle music application 1107, a display card for the vehicle's remaining battery power and remaining driving range 1108, and a display card for the vehicle's 360-degree (°) surround view function 1109. The in-vehicle map application search box 1105 may include user-defined controls for going home 11051 and going to work 11052. The function bar 1110 includes an icon 1111 for switching to the central control screen desktop, an icon 1112 for vehicle internal circulation, an icon 1113 for driver's seat heating function, an icon 1114 for driver's area air conditioning temperature display, an icon 1115 for passenger's area air conditioning temperature display, an icon 1116 for passenger's seat heating function, and an icon 1117 for volume settings.

[0161] When the vehicle detects that the concentration of pollutants in the cabin is greater than or equal to the second threshold through the smoke sensor or PM2.5 sensor, the graphical user interface (GUI) shown in Figure 11(b) can be displayed on the vehicle's central control screen.

[0162] As shown in Figure 11(b), the GUI includes voice broadcast content 1118 and voice assistant 1119. The voice assistant 1119 can prompt the user with "The concentration of pollutants in the cabin is too high. Do you want to turn on the regional odor function?" through voice broadcast.

[0163] As shown in Figure 12, after the vehicle detects the user's voice command to "activate the odor removal function", the vehicle's central control screen can display the divided areas in the cabin and a prompt box 1120. The prompt box 1120 is used to prompt the user to "select the area to remove odors". After the vehicle detects that the user clicks the control of "Area 1", as shown in Figure 13, the vehicle can control the air conditioner to turn on, control the air purification system to turn on, control the exhaust fan to turn on, close the exhaust damper, fully open the exhaust damper, and control the electric air outlet of Area 1 to avoid blowing air onto the user.

[0164] It should be noted that the first area in method 1000 may include "area 1", and this application does not limit the way the area is divided in the cockpit.

[0165] It should also be noted that the user-vehicle interaction scenarios shown in Figures 11 to 13 are merely illustrative examples and do not constitute a limitation on this application. Those skilled in the art can modify the scenarios shown in Figures 11 to 13 according to actual needs.
