Description

Technical Field

[0001] The present invention belongs to the technical field of automobile air-conditioning control, and in particular relates to an automobile air-conditioning intelligent air outlet control method and system. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] The air conditioner of new energy vehicles is a major energy consumer in the vehicle's thermal management system. It is not only used frequently but also has a variety of usage scenarios. Currently, when the car's air conditioner is turned on, the air will be blown regardless of whether there are people sitting in the passenger seat or the back seat, which will increase unnecessary energy consumption.

[0004] In addition, the air outlet direction of the car's air-conditioning outlet generally requires manual adjustment by the driver and passengers as needed, which poses a safety hazard to the driver. At present, the air outlet modes for different parts of the car are usually implemented based on image recognition, but image recognition requires the installation of an additional camera, and the recognition of the follow-up target and the adjustment of the angle conversion based on the image, which is relatively complex to implement and requires a large amount of calculation. Summary of the invention

[0005] In order to overcome the above-mentioned deficiencies of the prior art, the present invention provides an intelligent air outlet control method and system for an automobile air conditioner, which realizes the zoning control of the air outlet of the air conditioner and the wind following human movement control.

[0006] To achieve the above object, a first aspect of the present invention provides an intelligent air outlet control method for an automobile air conditioner, comprising the following steps:

[0007] When the air conditioner is turned on, the system monitors the passenger's seat entry signal in real time and controls the switch of the air conditioner outlets in each seating area to ensure that the air conditioner outlets in the seating area are turned on;

[0008] In response to feedback signals from the driver / passenger seat adjustment, the adjustment range of the air outlet direction of the air conditioner in the corresponding area is determined according to the adjustment range of the seat relative to the initial position;

[0009] The air outlet direction of the air conditioning outlet in the corresponding area is adjusted.

[0010] In some embodiments, a control strategy for adjusting the air outlet direction of the main / passenger seat is pre-established, and the amplitude of the air outlet direction of the air conditioner outlet in the corresponding area to be adjusted is determined according to the adjustment direction and amplitude of the main / passenger seat and the control strategy for adjusting the air outlet direction of the main / passenger seat;

[0011] Among them, the control strategy for adjusting the air outlet direction of the driver / passenger seat includes: the initial position parameters of the seat, the initial air outlet direction parameters of the air-conditioning outlet in the corresponding area, the left and right adjustment amplitude of the air outlet when the seat is adjusted up / down by a unit distance, and the correspondence between the up and down adjustment amplitude of the air outlet when the seat moves up / down by a unit distance.

[0012] In some embodiments, air outlet direction adjustment control strategies for the driver / passenger vehicle corresponding to different height ranges are pre-established, the user's designation of the height range is received, and the corresponding air outlet direction adjustment control strategies for the driver / passenger vehicle are determined.

[0013] In some embodiments, for different target parts, the main / co-pilot air outlet direction adjustment control strategies corresponding to different height ranges are pre-established, the user's designation of the target part and height range is received, and the corresponding main / co-pilot air outlet direction adjustment control strategies are determined.

[0014] In some embodiments, when there are people sitting in the back row, the rear airflow direction adjustment control strategy is determined according to the seat position of the occupant;

[0015] The rear airflow direction adjustment control strategy includes: the airflow direction of the rear air outlet when there are passengers sitting on only one side and when there are passengers sitting on both sides.

[0016] In some embodiments, multiple sensors are evenly arranged on the backrest of the seat to establish a space coordinate system in the vehicle, and the position of each sensor in the space coordinate system when the center of each air-conditioning outlet and the primary / secondary seat are in the initial position is determined;

[0017] In response to feedback signals from driver / passenger seat adjustment, pressure distribution data on the seat is acquired, a designated human body part is identified, and a position of a target part is estimated based on the designated human body part;

[0018] Based on the estimated position of the target part relative to the position of each pressure sensor, and the position of each pressure sensor relative to the center of the air-conditioning outlet in the area where the seat is located, the estimated position of the target part relative to the center of the air-conditioning outlet is obtained, and the extent to which the air outlet direction of the air-conditioning outlet needs to be adjusted is determined.

[0019] A second aspect of the present invention provides an intelligent air outlet control system for an automobile air conditioner, comprising:

[0020] The air outlet switch control module is configured to monitor the passenger seat entry signal in real time when the air conditioner in the car is turned on, and control the switch of the air conditioner air outlet in each seating area to ensure that the air conditioner air outlet in the seating area is turned on;

[0021] The air outlet direction adjustment trigger module is configured to trigger the air outlet direction adjustment module to perform work in response to the feedback signal of the driver / passenger seat adjustment;

[0022] The air outlet direction adjustment module is configured to determine the adjustment range of the air outlet direction of the air conditioning outlet in the corresponding area according to the adjustment range of the seat relative to the initial position; and adjust the air outlet direction of the air conditioning outlet in the corresponding area.

[0023] A third aspect of the present invention provides an electronic device, comprising a processor and a memory, wherein the memory stores computer instructions, and when the computer instructions are executed by the processor, the electronic device executes the method described.

[0024] A fourth aspect of the present invention provides a computer-readable storage medium having a computer program stored thereon, wherein the program implements the method described when executed by a processor.

[0025] A fifth aspect of the present invention provides a computer program product, the computer program product comprising a computer program, and the computer program implements the method when executed by a processor.

[0026] One or more of the above technical solutions can realize the zoned control of air conditioning outlet by detecting the passengers. The outlet in the occupied area is automatically turned on, and the outlet in the unoccupied area is promptly turned off. At the same time, the change range of the seat is approximately replaced by the change range of the human body. For the main driver or co-driver seat with someone sitting, when the seat is adjusted, the outlet direction is adjusted synchronously, and the outlet is realized to follow the flow, which not only ensures the comfort of passengers, but also effectively avoids energy waste, and indirectly improves the endurance of new energy vehicles. Compared with the method based on image recognition of target parts, it saves energy consumption and computing resources. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be construed as being limited to the embodiments described herein. Instead, these embodiments are provided to provide a more thorough and complete understanding of the present application. It should be understood that the drawings and embodiments of the present application are only for exemplary purposes and are not intended to limit the scope of protection of the present application.

[0033] In the description of the embodiments of the present application, the term “including” and similar terms should be understood as open inclusion, that is, “including but not limited to.” The term “based on” should be understood as “based at least in part on.”

[0034] Figure 1 The schematic diagram of the distribution of seats and air-conditioning outlets inside the vehicle is shown. In the figure, the main driver's air outlet 1 and the main driver's air outlet 2 are two air outlets corresponding to the main driver's area A1, the co-driver's air outlet 1 and the co-driver's air outlet 2 are two air outlets corresponding to the co-driver's area A2, and the rear row air outlet is the air outlet corresponding to the rear row area, which can be divided into the rear left area A3 and the rear right area A4.

[0035] Figure 2 The application environment of the intelligent air outlet control method for automobile air conditioners in one or more embodiments of the present invention is shown. Specifically, the air conditioning system A202 is respectively connected to the seat adjustment module A201, the occupant detection module A204, the air outlet control module A203 and the vehicle machine module A205. The air conditioning system A202 can detect the seat occupant from the occupant detection module A204, and then control the start and stop of the air conditioner as needed in different areas. When the feedback signal of the seat adjustment is obtained from the seat adjustment module A201, the amplitude of the air outlet direction of the air conditioner outlet in the area where the seat is located is determined according to the adjustment direction and amplitude of the seat, and then the corresponding control instructions are sent to the air outlet control module A203. The vehicle machine module A205 can receive voice commands and obtain the working status of each air conditioner outlet in real time.

[0036] Specifically, the occupant detection module A204 is implemented based on sensors set on the main driver's seat, co-driver's seat and rear seats. It can simultaneously detect whether there are people sitting in the main driver's seat in the main driver's area A1, the co-driver's seat in the co-driver's area A2, the left rear seat in the rear left area A3 and the right rear seat in the rear right area A4, and send the information to the air-conditioning system A202.

[0037] The seat adjustment module A201 can simultaneously detect the up and down and / or forward and backward adjustment of the main driver's seat in the main driver's area A1 and the co-driver's seat in the co-driver's area A2, and at the same time feed back the current real-time position information to the air conditioning system A202. The air conditioning system A202 will instruct the air outlet control module A203 to adjust the blowing direction of the corresponding area.

[0038] The air outlet control module A203 can simultaneously control the main driver's air outlet 1, the main driver's air outlet 2, the co-driver's air outlet 1, the co-driver's air outlet 2 and the rear air outlets, wherein the main driver's air outlet 1 and the main driver's air outlet 2 provide air outlet to the main driver area A1 at the same time, the co-driver's air outlet 1 and the co-driver's air outlet 2 provide air outlet to the main driver area A2 at the same time, and the rear air outlet provides air outlet to the rear left area A3 and the rear right area A4 at the same time; each air outlet can be electrically adjusted up and down and / or left and right, and can be closed and / or opened; the air outlet control module A203 needs to execute and feedback the execution result to the air-conditioning system A202.

[0039] The air-conditioning system A202 includes an air-conditioning control module and an air-conditioning box, which can realize functions such as cooling, heating, and dehumidification of the crew cabin, and supports independent adjustment of the temperature and air outlet mode on the driver's side, the co-driver's side, and the rear row; and maintains communication with the seat adjustment module A201, the occupant detection module A204, the air outlet control module A203, and the vehicle computer module A205, constantly determines the state of the air outlet and adjusts the corresponding air outlet.

[0040] The vehicle computer module A205 can always display the air outlet status information fed back by the current air-conditioning system A202, and can accept user instructions and convey the corresponding instructions to the air-conditioning module A202.

[0041] One or more embodiments of the present invention provide a method for intelligent air outlet control of automobile air conditioners, which detects in real time whether there are people sitting in each seat in the current car, and reports the results to the occupant detection module; combined with the detection of whether there are people sitting in the current seat, it is determined whether the air-conditioning outlets in the current area need to be closed or opened, and then through the detected up and down and / or left and right adjustment of the driver's and / or co-driver's seats, according to the initially defined target part and the initial corresponding position relationship of the air outlet, the air outlet is compensated up and down and / or left and right, so that it can synchronously follow the target part. Specifically, the method includes the following steps:

[0042] S301: When the air conditioner in the vehicle is turned on, the passenger seat entry signal is monitored in real time, and the air conditioner outlets in each seating area are controlled to ensure that the air conditioner outlets in the seating area are turned on;

[0043] S302: In response to the feedback signal of the driver / passenger seat adjustment, determine the adjustment range of the air outlet direction of the air conditioner outlet in the corresponding area according to the adjustment range of the seat relative to the initial position;

[0044] S303: Adjust the air outlet direction of the air-conditioning outlets in the corresponding area.

[0045] In step S301, turning on the air-conditioning system to achieve cooling, heating or ventilation in the vehicle is a prerequisite for implementing the present application.

[0046] In some embodiments, whether an occupant is seated is detected based on a sensor disposed on the seat. Specifically, the sensor may be a pressure sensor, and when the pressure value sensed by the pressure sensor is within a certain set range, it is considered that an occupant is seated.

[0047] By turning on the air conditioner only for the areas where there are passengers, energy consumption can be reduced. As an example, if only the main driver and front passenger seats are occupied, the rear air conditioning vents are closed.

[0048] In step S302, the driver / passenger seat adjustment is moved, which means that the occupant's posture is adjusted, so the wind direction of the air outlet is likely to deviate from the target part. Therefore, in one or more embodiments of the present invention, the change of the seat is used as the opportunity to determine whether the direction of the air outlet needs to be adjusted. Compared with the machine vision-based method that needs to monitor the user's movements at all times, the energy consumption and computing power are lower.

[0049] The target part is a designated part of the target user. As an example, the facial breathing point can be used as the target part.

[0050] As a specific implementation of step S302, since the driver / passenger seat can be adjusted to a large extent, the posture of the driver / passenger passenger has a large change space, while the rear seats cannot be adjusted. When the rear passengers sit in a sitting position, the posture change range is not large, and the main change is the sitting position. Based on this, when the posture of the seat only considers its up, down, left, and right positions, the initial air outlet directions of the driver / passenger and rear air outlets, as well as the adjustment range with the seat adjustment, are calibrated respectively.

[0051] Air outlet direction calibration for the main / co-pilot area:

[0052] It should be noted that when the air outlet direction is fixed, when the main / auxiliary seat is adjusted up and down or forward and backward, the deviation in the air outlet direction felt by the occupants is more obvious, so only the up and down or forward and backward adjustment of the seat is considered here.

[0053] Define the adjustment range of the main driver's air outlet 1, main driver's air outlet 2, co-driver's air outlet 1, and co-driver's air outlet 2 from left to right: 0-100%, and the adjustment range from bottom to top: 0-100%.

[0054] Define the driver / passenger seat adjustment range from bottom to top: 0-100%, and the front to back adjustment range: 0-100%.

[0055] Define the initial position of the driver / passenger seat. For example, define the initial position as: when the front and rear and up and down positions are a% and b% respectively, adjust the direction of the air outlet in the user's area to face the target area, and use the air outlet direction at this time as the air outlet calibration direction of the initial position of the driver / passenger seat. For example, the up and down and left and right positions of the main driver's air outlet 1 corresponding to the calibration direction of the main driver's air outlet are e% and f% respectively, and the up and down and left and right positions of the main driver's air outlet 2 are e% and (100-f)% respectively, and the same applies to the passenger side. The corresponding relationship between the initial position of the driver / passenger seat and the direction of the air outlet of the air conditioner in the driver / passenger area is obtained, and all subsequent adjustments are compensated based on the initial corresponding position.

[0056] Air outlet direction calibration for the rear area:

[0057] Define the rear air outlet adjustment range from left to right: 0-100%, from bottom to top adjustment range: 0-100%.

[0058] For the rear seats, calibration is performed for the situations where there are passengers sitting on only one side and passengers sitting on both sides.

[0059] Only when the rear left seat is occupied, the direction of the rear air outlet is adjusted to face the breathing point of the user's face. The two air outlet directions at this time are recorded as the calibrated directions. For example, the up and down and left and right positions are e% and f%, respectively. Similarly, only when the rear right seat is occupied, the air outlet direction is calibrated, for example, the up and down and left and right positions are e% and (100-f)%, respectively.

[0060] If there are people sitting in the left and right areas of the rear row, the calibration direction is: the up and down positions are e%, and the left and right positions are swept in a circular manner from 0-100%-0.

[0061] The air outlet direction of the driver / passenger area is calibrated according to the seat adjustment range:

[0062] When the driver / passenger seat is adjusted, the target part will change relative to the air outlet direction. For example, when adjusting forward or upward, the facial breathing point will move upward relative to the air outlet direction. When adjusting backward or downward, the facial breathing point will move downward relative to the air outlet direction. Therefore, it is also necessary to calibrate the adjustment range of the seat and the adjustment range of the air outlet direction of the air conditioner in the corresponding area.

[0063] It is understandable that the above initialization operation can be pre-calibrated at the factory stage, for example, based on users of different heights and different target parts, and then for different target parts, the following main / passenger air outlet direction adjustment control strategies are summarized: the initial seat position parameters corresponding to different height ranges, the initial air outlet direction parameters of the air-conditioning outlets in the corresponding areas, the amplitude of the left and right adjustment of the air outlet when the seat is adjusted up / down by a unit distance, and the correspondence between the amplitude of the up and down adjustment of the air outlet when the seat moves up / down by a unit distance. Based on this, users can choose the air outlet direction control strategy that suits them according to their favorite target parts and their own height.

[0064] After the above calibration process, in response to the feedback signal of the driver / passenger seat adjustment, the adjustment direction and amplitude of the seats and the above-mentioned driver / passenger seat air outlet direction adjustment control strategy can be used to determine the amplitude of the air outlet direction of the air conditioning outlet in the corresponding area that needs to be adjusted.

[0065] As an example, take the main driving area detection as an example. If someone is sitting and the main driving seat is still in the default position a% and b%, then the main driving air outlet 1 is opened and maintained at the up / down / left / right position e% and f% to discharge air, and the main driving air outlet 2 is opened and maintained at the up / down / left / right position e% and (100-f)% to discharge air, so that the air is discharged to the breathing point of the face. Assume that every time the main driving seat moves forward by x%, the air outlet direction is adjusted by z% to the left and right, and every time the main driving seat moves upward by y%, the air outlet direction is adjusted by w%. If the passenger on the driver's side moves the seat forward to the (ax)% position, the air outlet needs to adjust the air outlet direction left and right by z% because the passenger's facial breathing point moves forward. At this time, the air outlet 1 on the driver's side is adjusted to the up / down / left / right position of e% and (f+z)% to discharge air, and the air outlet 2 on the driver's side is adjusted to the up / down / left / right position of e% and (100-fz)% to discharge air. For every x% forward or backward movement of the seat, the air outlet direction will be adjusted left and right by z%. If the passenger on the driver's side moves upward again on this basis, Move the seat to the (b+y)% position. At this time, the air outlet needs to adjust the air outlet direction up and down by w% because the passenger's facial breathing point moves upward. At this time, the main driver's side air outlet 1 is adjusted to the up and down / left and right positions of (e+w)% and (f+z)% to discharge air, and the main driver's side air outlet 2 is adjusted to the up and down / left and right positions of (e+w)% and (100-fz)% to discharge air. For every y% movement of the seat up or down, the air outlet wind direction is adjusted up and down by w%. The adjustment logic of the co-pilot area is the same as that of the main driver's side area.

[0066] Similarly, for the rear passengers, the above calibration process can also be carried out. For the rear seats, the following rear airflow direction adjustment control strategies are obtained for different target parts: the initial airflow direction parameters of the air-conditioning outlets corresponding to different height ranges. Based on this, according to the position of the occupants, the rear air-conditioning outlets are controlled to discharge air in the calibrated outlet direction. As an example, only when there is someone sitting in the left rear seat, the rear air outlet is opened and the up / down / left / right positions are maintained at e% and f% to discharge air. Only when there is someone sitting in the right rear seat, the rear air outlet is opened and the up / down / left / right positions are maintained at e% and (100-f)% to discharge air. If there are people sitting in both the left and right rear seats, the rear air outlet is opened and the up / down positions are maintained at e%, and the left and right positions are swept from 0-100%-0 in a cycle to discharge air.

[0067] Of course, users have personalized needs. For example, different passengers have different requirements for target areas, so this function can also be calibrated by the user. It is understandable that the owner can calibrate the air outlet direction of the air conditioner corresponding to each seat area according to the situation of the passengers who often take the car, so that it better meets their own comfort requirements.

[0068] Based on the above technical solution, the air conditioning can be adjusted to move with the passengers in the occupied areas, and the air can be turned off in the unoccupied areas, thereby achieving intelligent air control and effectively reducing energy consumption.

[0069] By establishing outlet air outlet direction control strategies corresponding to different height ranges and different target parts, the wind can be moved with the person. However, for cars shared by family members, or public cars of companies or organizations, the above implementation scheme requires frequent calibration or selection of calibrated strategies, which is obviously cumbersome, because the occupants on each seat are not fixed, especially the occupants on the main driver / co-pilot seat are not fixed, and the above implementation scheme does not take into account the adjustment of the backrest.

[0070] As another specific implementation method of step S302, in order to further improve the intelligence of the air outlet direction tracking of the air conditioner and make it adaptable to users of different heights, in some embodiments, multiple sensors are evenly arranged on the seat backrest, which responds to the feedback signal of the driver / passenger seat adjustment, obtains the pressure distribution data on the seat, identifies designated human body parts, such as shoulders and neck, and estimates the position of the target part according to the human body proportions.

[0071] Specifically, when a person sits on the back of a chair, the pressure on the back of the chair will have an obvious rule that the pressure in the middle is greater than that on the sides, and the pressure on the neck is very small or cannot be sensed. Considering that the head is usually, the designated target part can be estimated based on the distribution of the hips, shoulders, neck and other parts. As an example, the shoulders and neck can be regarded as designated parts of the human body. According to the characteristic that the distance from the shoulders to the top of the head is about 28-30 cm, the center line of the spine is determined according to the pressure distribution data, and the position 14-15 cm above the highest point of the identified torso area on the center line is estimated as the facial breathing point. Of course, for the driver, the head must be kept upright, so the highest point of the identified torso area is still a certain distance from the actual junction of the shoulder and neck, so a certain compensation distance can also be set. Similarly, the position of other target parts can be estimated based on the proportions of the human body.

[0072] A spatial coordinate system is established with any point on the vehicle as the origin, and the positions of the centers of the air-conditioning vents and the sensors in the spatial coordinate system when the seats are in the initial positions are determined. In response to the feedback signals of the adjustment of the driver / passenger seat, the pressure distribution data on the seats is obtained, and the designated human body parts are identified, and then the position of the target parts is estimated. According to the estimated positions of the target parts relative to the positions of the pressure sensors and the positions of the pressure sensors relative to the centers of the air-conditioning vents in the area where the seats are located, the estimated positions of the target parts relative to the centers of the air-conditioning vents are obtained, that is, the target direction of the air-conditioning vents when the air-conditioning vents are facing the target parts, and the amplitude of the air-conditioning vents that need to be adjusted is determined.

[0073] Based on this, no matter how the seat is adjusted or what the height of the occupant is, it is possible to estimate how the air outlet direction should be adjusted, thus achieving adaptive control.

[0074] At the same time, the air-conditioning system will feed back the actual air outlet position information after adjustment to the vehicle system. The vehicle system has an interface that can display the current air outlet status, allowing users to see the air outlet conditions in the car in real time, and can also instruct the corresponding area to open or close the air outlet.

[0075] Figure 4 This is a flow chart of the intelligent air outlet control method of an embodiment of the present application. The present invention aims to achieve intelligent air outlet control and effectively reduce energy consumption by optimizing the air outlet scheme based on the situation of the passengers in the vehicle after the user uses the vehicle and turns on the air conditioner, so that the wind follows the passengers in the area where there are passengers, and the air outlet is turned off in the area where there are no passengers. Figure 4 A flow chart of an embodiment is provided for expanded description.

[0076] A400: Turning on the air conditioning system to achieve cooling, heating or ventilation in the vehicle is a prerequisite for realizing this application. After turning on the air conditioning system, the air conditioning system will combine the relevant information collected by the seat adjustment module and the occupant detection module, make a comprehensive judgment, and instruct the air outlet adjustment module and the vehicle system to execute and display;

[0077] A401: After the air conditioner is turned on, the occupant detection module is used to determine whether there are people sitting in the main driver's seat and the front passenger seat. If there are no people sitting in the area, the corresponding area air outlet is closed and S401 is executed. If there are people sitting in the area, S402 is executed. At the same time, it is detected whether there is someone sitting in the left rear seat, and combined with whether there is someone sitting in the right rear seat to comprehensively determine the air outlet condition of the rear air outlet;

[0078] A402: Determine whether the seats in the corresponding area are occupied in A401. For the areas where there are occupants, the air conditioning system will obtain the seat adjustment status detected by the seat adjustment module, dynamically adjust the air outlet position, and make judgments and compensations for the up / down / fore / aft adjustments of the main driver's seat and / or the co-pilot's seat. When up / down adjustment occurs but no fore / aft adjustment, only the up / down blowing position of each air outlet is adjusted to execute S403. When up / down adjustment and fore / aft adjustment occur, both the up / down and left / right blowing positions of each air outlet are adjusted to execute S404. When fore / aft adjustment occurs but no up / down adjustment, both the left / right blowing positions of each air outlet are adjusted to execute S405. For the rear area, it is necessary to continue to detect whether there is anyone in the rear right seat. When there is someone in the rear left seat and no one in the rear right seat, execute S406. When there is someone in the rear left seat and no one in the rear right seat, execute S407. When there is no one in the rear left seat and no one in the rear right seat, execute S408. When there is no one in the rear left seat and no one in the rear right seat, execute S409. The specific execution logic involved refers to the definition in Chapter A303, and the logic is calibrated by technicians in this field based on the actual vehicle or set by themselves. It is only used as an example here without specific limitation.

[0079] A403: After adjusting the air outlet through the above logic, the air conditioning system will synchronously feed back the execution result to the vehicle system, and display the air outlet status in real time through the display interface of the vehicle system, so that the user can know the current air outlet situation at any time and can perform corresponding operations.

[0083] The air outlet direction adjustment module is configured to determine the adjustment range of the air outlet direction of the air conditioning outlet in the corresponding area according to the adjustment range of the seat relative to the initial position; and adjust the air outlet direction of the air conditioning outlet in the corresponding area.

[0084] One or more of the above-mentioned embodiments provide an air-conditioning control method in which the wind follows the person and the air is output intelligently. The method can automatically follow the air-conditioning outlet to the target part by detecting the use of the vehicle by different users, and automatically open or close the air outlet in the corresponding area according to the sitting conditions of the front passenger and rear passengers, so as to achieve the optimal comfort of the area and reduce energy consumption at the same time.
