Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to an airflow control method, device, and vehicle. Background Technology

[0002] With the rapid development of the automotive industry, cars have become an integral part of life. Users' requirements for cars are no longer limited to transportation, but they are pursuing greater comfort inside the vehicle.

[0003] To enhance interior comfort, most vehicles are equipped with air conditioning and multiple air vents. The air conditioning system delivers air to the occupants through these vents, improving their experience and comfort.

[0004] Normally, the total air volume of an air conditioner is distributed by all air outlets. If passengers manually adjust the air volume of a specific air outlet, the air volume of other air outlets will also be forced to change, making intelligent control impossible and hindering the improvement of user experience and comfort. Summary of the Invention

[0005] This application provides an airflow control method, device, and vehicle to achieve intelligent control of vehicle air conditioning and improve user experience and comfort.

[0006] In a first aspect, embodiments of this application provide an airflow control method, including:

[0007] During air conditioner operation, upon receiving an air volume adjustment signal from any air outlet, the change in air volume is determined based on the air volume adjustment signal.

[0008] Based on the change in air volume, the opening of each air outlet that has not received an air volume adjustment signal is adjusted so that the air volume of each air outlet that has not received an air volume adjustment signal remains unchanged.

[0009] Based on the air volume change determined by the air volume adjustment signal, this application embodiment adjusts the opening of each air outlet that has not received the air volume adjustment signal, so that the air volume of each air outlet that has not received the air volume adjustment signal remains unchanged, thereby reducing the linkage effect between the air volume of each air outlet, realizing intelligent control of each air outlet, meeting diverse needs, and improving the user experience and comfort.

[0010] Optionally, the air volume change is the air volume change at each air outlet that has not received an air volume adjustment signal;

[0011] The adjustment of the opening of each air outlet that has not received an air volume adjustment signal based on the air volume change includes:

[0012] Based on the air volume change of each air outlet that did not receive an air volume adjustment signal, obtain the opening change of each air outlet that did not receive an air volume adjustment signal.

[0013] Based on the change in the opening of each air outlet that has not received an air volume adjustment signal, the opening of each air outlet that has not received an air volume adjustment signal is adjusted.

[0014] This application embodiment can determine the opening change of each air outlet that has not received an air volume adjustment signal by measuring the air volume change of each air outlet that has not received an air volume adjustment signal. Then, the opening is adjusted according to the opening change to keep the air volume of each air outlet that has not received an air volume adjustment signal constant, thereby avoiding the air volume adjustment signal affecting each air outlet that has not received an air volume adjustment signal and improving the experience and comfort of passengers.

[0015] Optionally, adjusting the opening of each air outlet that has not received an air volume adjustment signal based on the change in opening of each air outlet that has not received an air volume adjustment signal includes:

[0016] Based on the change in the opening of each air outlet that has not received an air volume adjustment signal and the current opening of each air outlet that has not received an air volume adjustment signal, determine the target opening of each air outlet that has not received an air volume adjustment signal.

[0017] Determine whether the target opening of each air outlet that has not received an air volume adjustment signal is within the preset opening range;

[0018] If it is determined that the target opening of each air outlet that has not received an air volume adjustment signal is within the opening range, then the opening of each air outlet that has not received an air volume adjustment signal is adjusted based on the change in the opening of each air outlet that has not received an air volume adjustment signal; otherwise, the total air volume of the air conditioner is adjusted based on the change in the air volume.

[0019] Before performing control adjustments, this embodiment pre-determines whether the target opening degree corresponding to the change in air volume is within a preset opening degree range. This determines whether the opening adjustment capability of the air outlet meets the adjustment requirements of the change in air volume. If it does, the opening degree can be adjusted according to the target opening degree. If it does not meet the requirements, the total air volume of the air conditioner is adjusted. By pre-determining whether the opening adjustment capability of the air outlet meets the air volume adjustment requirements, ineffective opening degree adjustment processes can be avoided, thus improving the efficiency of air volume adjustment.

[0020] Optionally, after determining the airflow change based on the airflow adjustment signal, the method further includes:

[0021] Based on the change in air volume, the total air volume of the air conditioner is adjusted so that the air volume of each air outlet that has not received an air volume adjustment signal remains unchanged.

[0022] In this embodiment, when passengers actively adjust the airflow of the air vents inside the vehicle, the total airflow of the air conditioner can be adjusted accordingly to keep the airflow of other air vents that are not actively adjusted by passengers unchanged. This avoids the airflow of other air vents that are not actively adjusted by passengers being affected by the linkage, realizes intelligent control of the air conditioner, meets the diverse needs of different passengers, and improves the user experience and comfort.

[0023] Optionally, the airflow adjustment signal is generated by the passenger triggering the damper adjustment structure in the air outlet;

[0024] The damper adjustment structure includes: a push-pull rod, a connecting rod, a damper rotor, and a sensor; wherein, the damper rotor is provided with a damper control end and a sensor control end, and the damper control end and the sensor control end rotate along the central axis of the damper rotor;

[0025] The push-pull rod is connected to one end of the connecting rod;

[0026] The other end of the connecting rod is connected to the damper control end of the damper rotor, and the damper control end is used to adjust the damper opening in the air outlet;

[0027] The sensor control terminal of the damper rotor is located at the trigger position of the sensor to trigger the sensor so that the sensor sends an air outlet opening adjustment signal.

[0028] Optionally, the method further includes:

[0029] After receiving the air conditioning start signal, it detects the distribution information of the passengers inside the vehicle;

[0030] Based on the distribution information of the passengers and the number of air vents on each seat in the vehicle, determine the air volume corresponding to each air vent in the vehicle.

[0031] Based on the air conditioning start signal, the air conditioning is controlled to start, and the air conditioning is controlled to deliver air to each air outlet in the vehicle according to the corresponding air volume of each air outlet.

[0032] This embodiment of the application, upon receiving an air conditioning start signal, first detects the distribution information of the occupants inside the vehicle. Then, based on the occupant distribution information and the information of the air vents on each seat, it determines the airflow volume corresponding to each air vent. Next, based on the air conditioning start signal, it controls the air conditioning to start and directs airflow to each vent according to its corresponding airflow volume, thereby achieving intelligent control of the air conditioning. This embodiment considers not only the occupant distribution information but also the information of the air vents on each seat. By combining the occupant distribution information and the air vent information, the relationship between the occupants and the air vents can be determined. Based on this relationship, the airflow volume corresponding to each vent can be determined, intelligently delivering airflow to each occupant to meet diverse needs and improve user experience and comfort.

[0033] Optionally, the passenger distribution information includes the passenger's location and number;

[0034] The step of determining the air volume corresponding to each air vent in the vehicle based on the distribution information of the passengers and the number of air vents on each seat includes:

[0035] Based on the total air volume of the air conditioner and the number of passengers, determine the air volume corresponding to each passenger;

[0036] Based on the distribution of the passengers and the number of air vents on each seat, the number of air vents corresponding to each passenger is obtained.

[0037] The air volume corresponding to each air outlet in the vehicle is determined based on the air volume corresponding to each passenger and the number of air outlets corresponding to each passenger.

[0038] In this embodiment, the air volume corresponding to each passenger is determined based on the total air volume of the air conditioner and the number of passengers. The number of air outlets corresponding to each passenger is obtained based on the distribution of passengers and the number of air outlets on each seat. Thus, the air volume corresponding to each air outlet is determined based on the air volume corresponding to each passenger and the number of air outlets corresponding to each passenger, thereby controlling the air conditioner to blow air effectively. This can reduce the airflow to seats where there are no passengers, making it suitable for practical applications.

[0039] Optionally, after controlling the air conditioner to deliver air to each air vent in the vehicle according to the corresponding air volume, the method further includes:

[0040] Real-time detection of the distribution information of passengers inside the vehicle;

[0041] Determine whether the distribution information of the passengers has changed;

[0042] If the distribution information of the passengers changes, the air volume corresponding to each air outlet in the vehicle is re-determined based on the number of air outlets on each seat in the vehicle and the changed distribution information of the passengers. The air conditioner is then controlled to deliver air to each air outlet in the vehicle according to the re-determined air volume corresponding to each air outlet in the vehicle.

[0043] In this embodiment, after the air conditioner is started, the distribution information of the passengers in the vehicle is continuously monitored in real time to determine whether the distribution information of the passengers has changed. Based on the changed distribution information of the passengers, the air volume corresponding to each air outlet is re-determined. Thus, during the operation of the air conditioner, the air volume corresponding to each air outlet can be intelligently adjusted in real time according to the changes in the passengers, thereby improving the experience and comfort of the passengers in the vehicle.

[0044] Secondly, embodiments of this application provide an airflow control device, including:

[0045] The determination module is used to determine the change in air volume based on the air volume adjustment signal received from any air outlet during air conditioner operation.

[0046] The control module is used to adjust the opening of each air outlet that has not received an air volume adjustment signal based on the air volume change, so as to keep the air volume of each air outlet that has not received an air volume adjustment signal constant.

[0047] Thirdly, embodiments of this application provide a vehicle including a memory and a processor. The memory stores a computer program that can run on the processor, and the processor executes the computer program to implement the audio processing method as described in any of the first aspects.

[0069] The applicant discovered that the total airflow of the vehicle's interior air conditioning system is typically distributed across all vents. This means that when any passenger manually adjusts the airflow from their assigned vent, the airflow from other vents is also forced to change, thus affecting the airflow experience for other passengers. Therefore, it is necessary to consider a new airflow control method to avoid mutual interference between vents, achieving intelligent control, meeting diverse user needs, and improving the overall experience and comfort.

[0070] To avoid mutual interference between air outlets, achieve intelligent control, meet diverse needs, and improve user experience and comfort, in the embodiments of this application, during air conditioner operation, upon receiving an air volume adjustment signal from any air outlet, control adjustment is performed according to the air volume adjustment signal to keep the air volume of each air outlet that has not received an air volume adjustment signal unchanged, thereby avoiding mutual interference between air outlets, achieving intelligent control, meeting diverse needs, and improving user experience and comfort.

[0071] First refer to Figure 1 , Figure 1 The diagram illustrates an application scenario according to an embodiment of this application. The device involved in this application scenario includes an in-vehicle host 101, an air conditioning controller 102, and an air conditioner 103. The in-vehicle host 101 and the air conditioning controller 102 can communicate. The air conditioning controller 102 is used to control the operation of the air conditioner 103.

[0072] The application scenario involves passengers adjusting the airflow at the vents while the air conditioning is running: After receiving an airflow adjustment signal from any vent, the vehicle-mounted unit 101 determines the change in airflow based on the signal. The vehicle-mounted unit 101 then sends this change in airflow to the air conditioning controller 102. Based on the change in airflow, the air conditioning controller 102 adjusts the airflow to ensure that the airflow from vents that have not received an airflow adjustment signal remains constant.

[0073] The following is combined Figure 1 Application scenarios, refer to Figures 2-8 This application describes an airflow control method provided according to exemplary embodiments. It should be noted that the above application scenarios are shown only to facilitate understanding of the spirit and principles of this application, and the embodiments of this application are not limited in any way. Rather, the embodiments of this application can be applied to any applicable scenario.

[0074] It should be noted that the implementation methods of this application can be applied to vehicle-mounted hosts, that is, the air volume control method provided by the exemplary implementation methods of this application can be executed on the vehicle-mounted host.

[0075] refer to Figure 2 , Figure 2 This is a schematic flowchart of an air conditioning method provided in an embodiment of this application. Figure 2 As shown, the method in the embodiments of this application may include:

[0076] Step 201: During air conditioner operation, upon receiving an air volume adjustment signal from any air outlet, determine the change in air volume based on the air volume adjustment signal.

[0077] In this embodiment, the vehicle interior typically has multiple air vents. The air conditioner delivers air to passengers in different locations through these vents. During air conditioner operation, passengers can send airflow adjustment signals by triggering the corresponding airflow adjustment button on the vent, thereby increasing or decreasing the airflow from the vent to meet their needs.

[0078] In this embodiment, airflow sensors can be installed at each air outlet to obtain the airflow volume of each outlet in real time. When an airflow adjustment signal is received from any air outlet, the change in airflow at each outlet after receiving the signal can be obtained from the airflow sensors, so that subsequent adjustment and control can be performed based on the change in airflow.

[0079] Step 202: Based on the change in air volume, adjust the opening of each air outlet that has not received an air volume adjustment signal or the total air volume of the air conditioner so that the air volume of each air outlet that has not received an air volume adjustment signal remains unchanged.

[0080] Here, the opening of the air outlet can be used to characterize the air outlet area. It can be understood that the larger the opening of the air outlet, the larger the air outlet area, and correspondingly, the greater the air volume.

[0081] The opening degree of the air outlet and the total air volume of the air conditioner are both factors affecting the air volume of the air outlet. Based on the above two influencing factors, this application provides the following three implementation methods for control and adjustment to keep the air volume of each air outlet that has not received an air volume adjustment signal constant.

[0082] In the first implementation, the opening of each air outlet that has not received an air volume adjustment signal can be adjusted based on the change in air volume, so that the air volume of each air outlet that has not received an air volume adjustment signal remains unchanged.

[0083] When the airflow of any air vent in the vehicle is adjusted by the user via a fan speed control signal, the airflow of the other air vents that have not received fan speed control signals will change accordingly, while the total airflow of the air conditioning system remains unchanged. In order to keep the airflow of the other air vents that have not received fan speed control signals constant, this embodiment of the application can adjust the opening of each air vent that has not received a fan speed control signal in reverse, based on the change in airflow of the vents that have not received a fan speed control signal, so that the airflow of the vents that have not received a fan speed control signal remains constant.

[0084] For example, when a user actively reduces the airflow from any air vent in the vehicle, in order to prevent the airflow from other air vents that have not been adjusted by the user from increasing, the opening of the other air vents that have not been adjusted by the user can be reduced, thereby blocking the excess airflow in the air duct and keeping the airflow from the other air vents that have not been adjusted by the user unchanged.

[0085] The degree of adjustment of the opening of each air outlet that has not been adjusted by the user can be determined based on the change in air volume of each air outlet that has not been adjusted by the user. It can be understood that the greater the change in air volume, the greater the degree of adjustment of the opening of the air outlet.

[0086] In scenarios where a user actively reduces the airflow from any air vent in the vehicle, this embodiment of the application reduces the opening of each air vent that has not received an airflow adjustment signal by measuring the change in airflow from the air vent that has not received an airflow adjustment signal. This can block excess airflow within the air duct, ensuring that the airflow from the air vent that has not been adjusted by the user remains constant, thus avoiding the influence of the air vent that has received an airflow adjustment signal, and consequently affecting the airflow experience of other passengers.

[0087] In the second implementation, the total air volume of the air conditioner can be adjusted based on the change in air volume, so that the air volume of each air outlet that has not received an air volume adjustment signal remains unchanged.

[0088] In this embodiment, after passengers actively increase or decrease the airflow of the air outlets, the total airflow of the air conditioner can be increased or decreased accordingly, thereby ensuring that the airflow of each air outlet that has not received an airflow adjustment signal remains unchanged. The degree of adjustment of the total airflow of the air conditioner can be determined based on the change in airflow at the air outlet that has received the airflow adjustment signal.

[0089] For example, when a passenger reduces the air volume of any air outlet from A to 0, the total air volume of the air conditioner can be reduced by A accordingly to ensure that the air volume of other air outlets that have not received the air volume adjustment signal remains unchanged.

[0090] In this embodiment of the application, when passengers actively increase or decrease the air volume of the air outlet, the total air volume of the air conditioner can be increased or decreased accordingly, so that the air volume of other air outlets that have not been adjusted by passengers remains unchanged. This avoids the air volume of the unadjusted air outlets being affected by the adjusted air outlets, thus affecting the passengers' air blowing experience.

[0091] In the third implementation, it can be determined in advance whether the opening adjustment capability of the air outlet that has not received the air volume adjustment signal meets the adjustment requirements of the air volume change. If its opening adjustment capability can meet the adjustment requirements of the air volume change, then adjustment is carried out based on the opening adjustment method. If its adjustment capability cannot meet the adjustment requirements of the air volume change, then adjustment is carried out by adjusting the total air volume of the air conditioner, so as to ultimately achieve the purpose of keeping the air volume of each air outlet that has not received the air volume adjustment signal unchanged.

[0092] This application embodiment considers that the opening degree of the air outlet has limited ability to adjust the air volume of the air outlet. When the air volume changes significantly, it may be impossible to maintain a constant air volume at each air outlet that has not received an air volume adjustment signal by adjusting the opening degree. Therefore, this application embodiment can pre-determine the opening degree adjustment capability of the air outlet. If the opening degree adjustment capability can meet the adjustment requirements of the air volume change, then adjustment is performed based on the opening degree adjustment method. If the adjustment capability of the air outlet cannot meet the requirements of the air volume change, then the total air volume of the air conditioner is directly adjusted.

[0093] Here, by pre-judging the opening adjustment capability of the air outlet that has not received an air volume adjustment signal, and then determining the adjustment method, the ineffective opening adjustment process can be avoided, and the adjustment efficiency can be improved.

[0094] This application embodiment, by adjusting the opening degree of each air outlet that has not received an air volume adjustment signal or the total air volume of the air conditioner, can keep the air volume of each air outlet that has not received an air volume adjustment signal constant, thereby avoiding the air volume of each air outlet that has not received an air volume adjustment signal being affected by the air volume adjustment signal, realizing intelligent control of each air outlet, meeting diverse needs, and improving the user experience and comfort.

[0095] The three implementation methods described above will be further elaborated below using different examples.

[0096] See Figure 3 , Figure 3 A flowchart illustrating another embodiment of the airflow control method provided in this application is shown below. Figure 3 As shown, the method includes:

[0097] Step 301: During air conditioner operation, upon receiving an air volume adjustment signal from any air outlet, determine the change in air volume based on the air volume adjustment signal.

[0098] Here, for the implementation of step 301, please refer to [link / reference]. Figure 2 The relevant descriptions in the embodiments will not be repeated here.

[0099] When adjusting the opening of each air outlet that has not received an air volume adjustment signal based on the change in air volume, so as to keep the air volume of each air outlet that has not received an air volume adjustment signal constant, the following steps 302-303 can be followed.

[0100] Step 302: Based on the air volume change of each air outlet that has not received an air volume adjustment signal, obtain the opening change of each air outlet that has not received an air volume adjustment signal.

[0101] Step 303: Based on the change in the opening of each air outlet that has not received an air volume adjustment signal, adjust the opening of each air outlet that has not received an air volume adjustment signal.

[0102] In this embodiment of the application, the change in air volume can be the change in air volume at each air outlet that has not received an air volume adjustment signal.

[0103] It is understood that there is a preset correspondence between the change in airflow at the air outlet and the change in the air outlet opening. Based on this preset correspondence and the change in airflow at the air outlet, the embodiment of this application can determine the change in the air outlet opening accordingly. This allows for the adjustment of the opening of each air outlet based on the change in opening of each outlet that has not received an airflow adjustment signal, ensuring that the airflow at each outlet that has not received an airflow adjustment signal remains constant.

[0104] This application embodiment uses a preset correspondence between air volume change and opening change, as well as the air volume change of each air outlet that has not received an air volume adjustment signal, to determine the opening change of each air outlet that has not received an air volume adjustment signal. Then, the opening is adjusted according to the opening change to keep the air volume of each air outlet that has not received an air volume adjustment signal constant, thereby reducing the linkage effect between the air volume of each air outlet and improving the experience and comfort of passengers.

[0105] See Figure 4 , Figure 4 A flowchart illustrating another embodiment of the airflow control method provided in this application is shown below. Figure 4 As shown, the method includes:

[0106] Step 401: During air conditioner operation, upon receiving an air volume adjustment signal from any air outlet, determine the change in air volume based on the air volume adjustment signal.

[0107] Here, for the implementation of step 401, please refer to [link / reference]. Figure 2 The relevant descriptions in the embodiments will not be repeated here.

[0108] Step 402: Based on the change in air volume, adjust the total air volume of the air conditioner so that the air volume of each air outlet that has not received an air volume adjustment signal remains unchanged.

[0109] This application embodiment takes into account that the air volume of each air outlet is affected by the total air volume of the air conditioner, and adopts the method of adjusting the total air volume of the air conditioner to keep the air volume of each air outlet that has not received the air volume adjustment signal unchanged.

[0110] Here, when passengers reduce or increase the air volume of any air outlet, the total air volume of the air conditioner can be reduced or increased accordingly based on the change in air volume at that air outlet, so that the air volume of each air outlet that has not received an air volume adjustment signal remains unchanged.

[0111] For example, when a passenger increases the air volume of any air outlet from 0 to A, or decreases it from A to 0, the embodiments of this application can correspondingly increase or decrease the total air volume of the air conditioner by A, thereby achieving the purpose of keeping the air volume of each air outlet that has not received an air volume adjustment signal unchanged.

[0112] In this embodiment, when passengers actively adjust the airflow of the air vents inside the vehicle, the total airflow of the air conditioner can be adjusted accordingly to keep the airflow of other air vents that are not actively adjusted by passengers unchanged. This avoids the airflow of other air vents that are not actively adjusted by passengers being affected by the linkage, realizes intelligent control of the air conditioner, meets the diverse needs of different passengers, and improves the user experience and comfort.

[0113] See Figure 5 , Figure 5 A flowchart illustrating an airflow control method provided in another embodiment of this application is shown below. Figure 5 As shown, the method includes:

[0114] Step 501: During air conditioner operation, upon receiving an air volume adjustment signal from any air outlet, determine the change in air volume based on the air volume adjustment signal.

[0115] Step 502: Based on the air volume change of each air outlet that has not received an air volume adjustment signal, obtain the opening change of each air outlet that has not received an air volume adjustment signal.

[0116] Here, the implementation method of steps 501-502 is described in [reference]. Figure 3 The relevant descriptions in the embodiments will not be repeated here.

[0117] When adjusting the opening of each air outlet that has not received an air volume adjustment signal based on the change in the opening of each air outlet that has not received an air volume adjustment signal, so as to keep the air volume of each air outlet that has not received an air volume adjustment signal constant, the following steps 503-505 can be performed.

[0118] Step 503: Determine the target opening of each air outlet that has not received an air volume adjustment signal based on the change in opening of each air outlet that has not received an air volume adjustment signal and the current opening of each air outlet that has not received an air volume adjustment signal.

[0119] In this embodiment, the opening range of each air outlet can be 0% to 100%. When the opening is 0%, the air outlet is completely closed. When the opening is 100%, the air outlet is completely open. The change in opening can include both the direction and the numerical value of the change. For example, the change in opening can be 20%, meaning an increase of 20%. A change in opening can be -20%, meaning a decrease of 20%.

[0120] In this embodiment, the target opening of each air outlet that has not received an air volume adjustment signal can be obtained by superimposing the aforementioned opening change amount on the current opening of each air outlet that has not received an air volume adjustment signal.

[0121] Step 504: Determine whether the target opening of each air outlet that has not received an air volume adjustment signal is within the preset opening range.

[0122] It should be noted that the ability of the air outlet opening to regulate airflow is not only affected by the aforementioned correspondence between changes in airflow and changes in opening, but is also limited by the hardware structure of the air outlet. When the air outlet opening is within a certain range, the impact of the hardware structure on the air outlet's opening regulation capability is negligible. However, when the air outlet opening exceeds the aforementioned certain range, due to the limitations of the hardware structure, the air outlet's opening regulation capability will be significantly weakened, and the aforementioned correspondence will no longer hold.

[0123] Therefore, this embodiment of the application can set a preset opening range based on the hardware structure of the air outlet to determine whether the target opening corresponding to the change in air volume exceeds the opening adjustment capability of the air outlet. Furthermore, the preset opening range can be ultimately determined by combining the user's usage habits and airflow comfort based on the hardware structure. For example, the preset opening range can be 30% to 70%.

[0124] Step 505: If it is determined that the target opening of each air outlet that has not received an air volume adjustment signal is within the opening range, then the opening of each air outlet that has not received an air volume adjustment signal is adjusted based on the change in the opening of each air outlet that has not received an air volume adjustment signal; otherwise, the total air volume of the air conditioner is adjusted based on the change in air volume.

[0125] Here, when the target opening of each air outlet that has not received an airflow adjustment signal is within the aforementioned preset opening range, the opening can be adjusted based on the change in opening of each air outlet that has not received an airflow adjustment signal. However, if the target opening of any air outlet that has not received an airflow adjustment signal exceeds the aforementioned preset opening range, the total airflow of the air conditioner can be adjusted based on the change in airflow, ultimately achieving the goal of keeping the airflow of each air outlet that has not received an airflow adjustment signal constant.

[0126] Before performing control adjustments, this embodiment pre-determines whether the target opening degree corresponding to the change in air volume is within a preset opening degree range. This determines whether the opening adjustment capability of the air outlet meets the adjustment requirements of the change in air volume. If it does, the opening degree can be adjusted according to the target opening degree. If it does not meet the requirements, the total air volume of the air conditioner is adjusted. By pre-determining whether the opening adjustment capability of the air outlet meets the air volume adjustment requirements, ineffective opening degree adjustment processes can be avoided, thus improving the efficiency of air volume adjustment.

[0127] In this embodiment, the aforementioned airflow adjustment signal can be generated by the passenger triggering the damper adjustment structure in the air outlet. See also... Figure 6 and Figure 7 The damper adjustment structure includes: a push-pull rod 61, a connecting rod 62, a damper rotor 63, and a sensor 64. The damper rotor 63 is provided with a damper control end 631 and a sensor control end 632, and the damper control end 631 and the sensor control end 632 rotate along the central axis of the damper rotor 63.

[0128] Push-pull rod 61 connects to one end of connecting rod 62;

[0129] The other end of the connecting rod 62 is connected to the damper control end 631 of the damper rotor 63. The damper control end 631 is used to adjust the opening of the damper in the air outlet.

[0130] The sensor control terminal 632 of the damper rotor 63 is located at the trigger position of the sensor 64 and is used to trigger the sensor 64 so that the sensor 64 sends an air outlet opening adjustment signal.

[0131] By moving the push-pull rod 61, the user can cause the damper control terminal 631 to rotate via the connecting rod 62. During rotation, the damper control terminal 631 can increase or decrease the damper opening, until the damper 66 in the air outlet is fully opened or closed. Simultaneously, the sensor control terminal 632 rotates along with the damper control terminal 631. During rotation, the sensor control terminal 632 triggers the sensor 64, causing it to send an air outlet opening adjustment signal. It is understood that different degrees of rotation of the sensor control terminal 632 result in different triggering degrees of the sensor 64, and consequently, different air outlet opening adjustment signals are sent by the sensor.

[0132] For example, see Figure 6 A pressure plate 641 can be installed on the sensor 64. The sensor controller 632 causes the sensor 64 to send different air outlet opening adjustment signals by pressing the pressure plate 641 to different degrees.

[0133] The above embodiments primarily address scenarios where passengers actively adjust the airflow from the vents during air conditioning operation, and do not cover the scenario of air conditioning startup. The following section will specifically describe the airflow control method in the context of the air conditioning startup scenario. Figure 8 As shown, the method includes:

[0134] Step 801: After receiving the air conditioning start signal, detect the distribution information of the passengers in the vehicle.

[0135] In this embodiment, occupants can send an air conditioning start signal by triggering the air conditioning start button inside the vehicle. Upon receiving the air conditioning start signal, this embodiment detects the distribution information of the occupants inside the vehicle.

[0136] In this embodiment, the distribution of occupants inside the vehicle can be detected using an in-vehicle camera. Alternatively, the distribution can be detected using pressure sensors located in each seat. Alternatively, the distribution can be detected by monitoring the status of the seatbelts in each seat.

[0137] In this embodiment, when detecting the distribution information of passengers inside the vehicle using the in-vehicle camera, a detection signal can be sent to the in-vehicle camera after receiving the air conditioning start signal. Upon receiving the detection signal, the in-vehicle camera acquires and transmits the in-vehicle image back. This embodiment pre-stores an image recognition algorithm for performing image recognition on the in-vehicle image to determine the distribution information of passengers inside the vehicle.

[0138] In this embodiment, when detecting the distribution information of passengers in the vehicle using pressure sensors on each seat, upon receiving an air conditioning start signal, this embodiment collects the pressure values ​​from the pressure sensors on each seat and determines whether there are passengers in each seat based on the corresponding pressure value, thereby determining the distribution information of passengers in the vehicle. It can be understood that when the pressure value is greater than or equal to a pressure threshold, it can be determined that there are passengers in the seat. Here, the pressure threshold can be determined based on the pressure value when there are passengers in the seat.

[0139] This embodiment detects the distribution information of passengers in the vehicle by detecting the status of the seat belts on each seat. Upon receiving an air conditioning start signal, this embodiment obtains the seat belt status of each seat via the seat belt switches. Specifically, the seat belt switch is in the closed state after a passenger enters the vehicle and fastens their seat belt. The seat belt switch is in the open state after a passenger unfastens their seat belt and exits the vehicle. This embodiment detects the seat belt switch status of each seat after receiving the air conditioning start signal to determine the distribution information of passengers in the vehicle.

[0140] Step 802: Determine the air volume corresponding to each air outlet based on the distribution information of passengers and the information of air outlets on each seat in the vehicle.

[0141] Here, the passenger distribution information can include the location and number of passengers. In this embodiment, the location and number of passengers can be determined by an in-vehicle camera, pressure sensors on each seat, or seatbelt switches on each seat.

[0142] The information regarding the air vents at each seat can include the number of air vents at each seat, that is, the number of air vents corresponding to each seat. Air vents are installed in the corresponding area of ​​each seat in the vehicle to provide airflow to the occupants in that seat. For example, typically two air vents are installed in the area corresponding to the driver's seat on the main control panel to provide airflow to the driver. Accordingly, the number of air vents at the driver's seat is 2. Here, in this embodiment, the number of air vents at each seat can be determined through the vehicle's configuration information.

[0143] In this embodiment of the application, the number of air vents corresponding to each passenger can be determined based on the distribution location and number of passengers, as well as the number of air vents on each seat, thereby determining the air volume of each air vent.

[0144] Understandably, for air vents corresponding to each passenger, the airflow can be increased to achieve effective air delivery. For air vents where no one is seated, the airflow can be reduced to avoid ineffective airflow.

[0145] Here, by analyzing the distribution and number of passengers, as well as the number of air vents on each seat, the airflow of each vent can be intelligently adjusted to achieve intelligent control of the air conditioning, thereby enhancing the user experience and comfort.

[0146] In some embodiments, the air volume ratio corresponding to each air outlet can also be determined by the distribution information of passengers and the information of the air outlets on each seat in the vehicle.

[0147] Similarly, based on the distribution and number of passengers, as well as the number of air vents on each seat, the air vent corresponding to each passenger can be determined, and thus the air volume ratio of each air vent can be determined.

[0148] Specifically, for air vents corresponding to each passenger, the airflow ratio of the vent can be increased to achieve effective air delivery. For air vents in areas where there are no passengers, the airflow ratio of the vent can be decreased to avoid ineffective air delivery.

[0149] Step 803: Based on the air conditioner start signal, control the air conditioner to start and control the air conditioner to deliver air to each air outlet according to the corresponding air volume of each air outlet.

[0150] In this embodiment, based on determining the air volume corresponding to each air outlet, the air conditioner can be started according to the air conditioner start signal, and at the same time, the air conditioner can be controlled to deliver air to each air outlet according to the air volume corresponding to each air outlet.

[0151] Alternatively, based on determining the air volume ratio corresponding to each air outlet, the air conditioner can be started according to the air conditioner start signal, and at the same time, the air conditioner can be controlled to deliver air to each air outlet according to the air volume ratio corresponding to each air outlet.

[0152] Step 804: During air conditioner operation, upon receiving an air volume adjustment signal from any air outlet, determine the change in air volume based on the air volume adjustment signal.

[0153] Step 805: Based on the change in air volume, adjust the opening of each air outlet that has not received an air volume adjustment signal or the total air volume of the air conditioner so that the air volume of each air outlet that has not received an air volume adjustment signal remains unchanged.

[0154] Here, the implementation method of steps 804-805 is described in [reference]. Figure 2 The relevant descriptions in the embodiments will not be repeated here.

[0155] In this embodiment, upon receiving an air conditioning start signal, the distribution information of the occupants inside the vehicle is first detected. Then, based on the occupant distribution information and the information of the air vents on each seat, the airflow volume corresponding to each air vent is determined. Next, based on the air conditioning start signal, the air conditioning is started and controlled to deliver air to each vent according to its corresponding airflow volume, thus achieving intelligent control of the air conditioning. Specifically, by determining the relationship between the occupants and the air vents on each seat, the airflow volume corresponding to each vent can be intelligently determined, intelligently delivering air to each occupant to meet diverse needs and improve user experience and comfort.

[0156] The following section details the specific methods for determining the air volume corresponding to each air outlet.

[0157] In determining the air volume corresponding to each air outlet in this embodiment, the air volume corresponding to each passenger can be determined first based on the total air volume of the air conditioner and the number of passengers; then, based on the distribution of passengers and the number of air outlets on each seat, the number of air outlets corresponding to each passenger can be obtained; next, based on the air volume corresponding to each passenger and the number of air outlets corresponding to each passenger, the air volume corresponding to each air outlet can be determined.

[0158] Here, the total airflow of the air conditioner can be determined by the air conditioner setting. Users can select the air conditioner setting when starting the air conditioner. This embodiment of the application determines the total airflow based on a preset correspondence between air conditioner settings and total airflow, as well as the air conditioner setting selected by the user. If the user does not select an air conditioner setting when starting the air conditioner, the air conditioner setting is determined based on the actual temperature inside the vehicle and a preset correspondence between the vehicle's interior temperature and the air conditioner setting. The total airflow is then determined based on this air conditioner setting. The actual temperature inside the vehicle can be obtained from temperature sensors installed inside the vehicle.

[0159] In this embodiment, the airflow rate for each passenger can be determined based on the ratio between the total airflow rate of the air conditioner and the number of passengers. For example, the ratio between the total airflow rate of the air conditioner and the number of passengers can be used to determine the airflow rate for each passenger.

[0160] At the same time, based on the distribution of passengers in the vehicle and the number of air vents on each seat, the number of air vents corresponding to each passenger can be obtained.

[0161] For each passenger, the airflow volume for each air outlet corresponding to that passenger can be determined based on the corresponding airflow volume and the number of air outlets for that passenger. For example, the ratio between the corresponding airflow volume and the number of air outlets for that passenger can be used to determine the airflow volume for each air outlet corresponding to that passenger. That is, the airflow volume for that passenger is evenly distributed among the air outlets corresponding to that passenger to achieve effective airflow. For air outlets located on seats without passengers, no airflow distribution is required to avoid ineffective airflow.

[0162] For example, the driver's seat can have two air vents, the front passenger seat can have two air vents, and the rear seats can have one air vent. When there is one passenger in the driver's seat and one in the rear seats, and no passenger in the front passenger seat, the total airflow can be evenly distributed to the two passengers to obtain the corresponding airflow for each passenger. For the two air vents in the driver's seat, the airflow corresponding to the driver's passenger is evenly distributed to the two driver's seat vents. For the two air vents in the rear seats, the airflow corresponding to the rear passenger is entirely distributed to the single rear air vent. Considering that there is no passenger in the front passenger seat, no airflow distribution is applied to the front passenger air vent.

[0163] According to the above method, this embodiment can distribute the total air volume of the air conditioner equally according to the number of passengers to achieve effective airflow to the passengers in the vehicle and avoid ineffective airflow. However, if there are few passengers in the vehicle but the total air volume of the air conditioner is large, if the air volume of each air outlet is determined according to the above method, the air volume of the air outlet corresponding to each passenger may be too large, which may easily cause the air outlet to whistle and cause discomfort to the passengers.

[0164] In response to this situation, for each passenger, this embodiment of the application can determine the air volume corresponding to each air outlet for that passenger based on the air volume corresponding to that passenger and the number of air outlets corresponding to that passenger. Then, it can detect whether the air volume of the air outlet corresponding to that passenger is greater than the maximum air volume threshold. If the air volume of the air outlet corresponding to that passenger is greater than the maximum air volume threshold, then the final air volume of the air outlet corresponding to that passenger is determined as the aforementioned maximum air volume threshold. Subsequently, the air volume difference between the total air volume of the air conditioner and the final air volume of the air outlet corresponding to each passenger is determined and distributed to the air outlets on other seats without passengers.

[0165] In other words, when distributing airflow to each air outlet, priority is given to allocating airflow to the air outlet corresponding to each passenger. If the airflow of the air outlet corresponding to each passenger reaches the maximum airflow threshold, the remaining airflow is distributed to air outlets in other air supply areas that do not have passengers, in order to avoid whistling from the air outlets and causing discomfort to the passengers.

[0166] For example, the driver's seat can have two air vents, the front passenger seat can have two air vents, and the rear seats can have one air vent. When only the driver's seat is occupied and the other seats are empty, the airflow B of each driver's seat vent can be set to half of the total airflow C of the air conditioning system, i.e., B = C / 2. If the airflow B of the driver's seat vent is greater than the maximum airflow threshold D, then the final airflow of each driver's seat vent is set to the maximum airflow threshold D, and the airflow difference E between the total air conditioning system airflow and the final airflow of the driver's seat vent is determined, where E = C - 2D. This airflow difference E is then evenly distributed to the air vents on the other seats.

[0167] According to the above embodiments, when the air conditioner is started, it can be controlled to deliver air to each air outlet according to the corresponding air volume. Based on this, the embodiments of this application also consider adjusting the air conditioner control method in real time according to changes in the number of passengers during operation, in order to achieve intelligent control of the air conditioner.

[0168] In some embodiments, after controlling the air conditioner to start based on the air conditioner start signal and controlling the air conditioner to deliver air to each air outlet according to the corresponding air volume, the method may further include:

[0169] During air conditioning operation, the distribution information of passengers inside the vehicle is monitored in real time, and it is determined whether the distribution information has changed. If the distribution information of passengers changes, the air volume corresponding to each air vent is re-determined based on the information of the air vents at each seat and the changed distribution information of passengers. The air conditioning is then controlled to deliver air to each air vent according to the re-determined air volume.

[0170] Here, during air conditioning operation, the distribution information of passengers inside the vehicle can be detected in real time, and it can be determined whether the distribution information of passengers has changed. Changes in the distribution information of passengers can include a decrease in the number of passengers, an increase in the number of passengers, or a change in the position of passengers.

[0171] If the number or distribution of passengers changes, the airflow volume for each air vent can be re-determined based on the changed number and distribution, as well as the information of the air vents at each seat. The air conditioning system will then be controlled to deliver air to each vent according to the newly determined airflow volume.

[0172] Here, the specific method for redetermining the air volume corresponding to each air outlet based on the information of the air vents on each seat in the vehicle and the changed distribution information of the passengers is the same as that in the above embodiment, and will not be repeated here.

[0173] In this embodiment, after the air conditioner is started, the distribution information of the passengers in the vehicle is continuously monitored in real time to determine whether the distribution information of the passengers has changed. Based on the changed distribution information of the passengers, the air volume corresponding to each air outlet is re-determined. Thus, during the operation of the air conditioner, the air volume corresponding to each air outlet can be intelligently adjusted in real time according to the changes in the passengers, thereby improving the experience and comfort of the passengers in the vehicle.

[0174] In some embodiments, if the number of passengers decreases, before redetermining the air volume corresponding to each air outlet based on the information of the air outlets on each seat in the vehicle and the changed distribution information of the passengers, the total air volume of the air conditioner can also be adjusted according to the decrease in the number of passengers.

[0175] Specifically, when adjusting the total air volume of the air conditioner based on the reduction in the number of passengers, the target reduction in air volume corresponding to the reduction in the number of passengers can be determined first based on the preset correspondence between the reduction in the number of passengers and the reduction in air volume; then, the total air volume of the air conditioner is reduced by the target reduction in air volume to obtain the adjusted total air volume of the air conditioner.

[0176] Here, when the number of passengers decreases, the total air volume of the air conditioner can be reduced accordingly, which can effectively reduce the energy consumption of the air conditioner.

[0177] Similarly, if the number of passengers increases, before re-determining the air volume corresponding to each air vent based on the information of the air vents on each seat in the vehicle and the changed distribution of passengers, the total air volume of the air conditioner can be adjusted according to the increase in the number of passengers.

[0178] Specifically, when adjusting the total air volume of the air conditioner based on the increase in the number of passengers, the target increase in air volume corresponding to the increase in the number of passengers can be determined first based on the preset correspondence between the increase in the number of passengers and the increase in air volume; then, the total air volume of the air conditioner is increased by the target increase in air volume to obtain the adjusted total air volume of the air conditioner.

[0179] When redetermining the air volume of each air outlet after adjusting the total air volume of the air conditioner, the air volume of each air outlet can be redetermined based on the adjusted total air volume of the air conditioner, the information of the air outlets on each seat in the vehicle, and the changed distribution information of the passengers.

[0180] In other words, during air conditioning operation, when the number of passengers in the vehicle decreases or increases, the total air volume of the air conditioner can be adjusted accordingly. Based on the adjusted total air volume, information about the air vents at each seat, and the changed number and distribution of passengers, the air volume corresponding to each air vent is then re-determined.

[0181] Here, the specific method for redetermining the air volume corresponding to each air outlet is the same as that in the above embodiment, and will not be repeated here.

[0182] In this embodiment, when the number of passengers changes, the total air volume of the air conditioner is adjusted accordingly. Based on the adjustment of the total air volume of the air conditioner, the air volume corresponding to each air outlet is re-determined. This not only improves the comfort of the users, but also takes into account the energy consumption of the air conditioner.

[0183] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.
