[0038] See also Figure 2 , which is a schematic diagram of the steps of an air conditioning air supply control method provided in one embodiment of the present application.

[0039] Specifically, the air conditioning air supply control method includes the following steps. According to different requirements, the order of some steps in the flowchart can be changed, and some steps can be omitted.

[0040] Step S10 , determining a target part from at least one body part of a vehicle occupant according to an air supply mode of the air conditioner.

[0041] In some embodiments of the present application, the at least one body part of the occupant includes the head, the abdomen, the left arm, and the right arm.

[0042] Specifically, the visual sensor 30 collects image data of the driver and passengers of the vehicle 1 and transmits it to the electronic device 10, which then uses image recognition technology (such as an algorithm based on key point detection, a semantic segmentation technology based on deep learning, an image recognition technology based on multimodal fusion, etc.) to analyze and identify the image data, thereby identifying at least one body part of the driver and passenger, and determining the position data of each body part in the at least one body part.

[0043] In other embodiments, the visual sensor 30 has the function of identifying at least one body part of the driver and passenger based on the collected image data and determining the position data of each body part.

[0044] In some embodiments of the present application, the electronic device 10 pre-configures the air supply mode of the air conditioner 20, such as a blowing mode towards people, a blowing mode away from people, an up and down sweeping mode, a left and right sweeping mode, an intelligent air supply mode, etc. The driver and passengers can select the air supply mode that meets their personal needs through the soft buttons on the vehicle-mounted touch interface.

[0045] Specifically, the target part is determined from at least one body part of the vehicle occupant according to the air supply mode of the air conditioner 20, including: if the air supply mode is a blowing mode towards people, the target part includes the head; if the air supply mode is a blowing mode avoiding people, the target part includes at least one body part; if the air supply mode is an up and down sweeping mode, the target part includes the head and abdomen; if the air supply mode is a left and right sweeping mode, the target part includes the left arm and the right arm.

[0046] In other embodiments, if the air supply mode of the air conditioner 20 is an intelligent air supply mode, the electronic device 10 can intelligently determine the air supply mode according to the thermal sensation of the driver and passenger. The thermal sensation includes but is not limited to very cold, cold, cool, slightly cool, neutral, slightly warm, warm, slightly hot, hot, and very hot. For example, if the thermal sensation of the driver and passenger is hot or very hot, the blowing mode on the person needs to be adopted to achieve rapid cooling; if the thermal sensation of the driver and passenger is slightly hot, the left and right sweeping mode or the up and down sweeping mode can be adopted to achieve cooling; if the thermal sensation of the driver and passenger is neutral, the avoiding blowing mode can be adopted.

[0047] It should be noted that how to calculate thermal sensation will be discussed later. Figure 3 The step S131 shown is described in detail, and will not be described again here to avoid repetition.

[0048] Step S11, adjusting the air outlet direction of the air door of the air conditioner based on the air supply mode and the position data of the target part.

[0049] Specifically, adjusting the air outlet direction of the air door of the air conditioner 20 based on the air supply mode and the position data of the target part includes: if the air supply mode is the blowing mode towards people, the air outlet direction of the air door is controlled to be toward the target part based on the position data of the target part; if the air supply mode is the blowing mode away from people, the air outlet direction of the air door is controlled to avoid the target part based on the position data of the target part; if the air supply mode is the up and down sweeping mode, the air outlet direction of the air door is controlled to reciprocate up and down between the target parts based on the position data of the target part; if the air supply mode of the air conditioner 20 is the left and right sweeping mode, the air outlet direction of the air door is controlled to reciprocate left and right between the target parts based on the position data of the target part.

[0050] Step S12, judging whether the air outlet direction of the air door meets the requirements according to the temperature data of the target part.

[0051] In some embodiments of the present application, the temperature data of the target site includes, but is not limited to, the radiation temperature of the target site and the air temperature around the target site.

[0052] In some embodiments of the present application, the temperature of the air outlet of the damper is relatively low, generally at 5-15°C. After the airflow is blown out of the air outlet, it will gradually rise due to the "entrainment effect", that is, the farther away from the air outlet, the higher the air temperature will be. For example, if the air supply mode is the blowing mode to the person, the wind blows towards the head, the radiation temperature of the head will be lower than the air temperature around the head, and there will be a large temperature gradient, that is, there will be a large difference between the radiation temperature of the head and the air temperature around the head.

[0053] Specifically, the specific steps of judging whether the air outlet direction of the damper meets the requirements according to the temperature data of the target part include: obtaining the temperature data of the target part, wherein the temperature data includes the radiation temperature of the target part and the air temperature around the target part. If the difference between the radiation temperature of the target part and the air temperature around the target part is within the temperature difference range corresponding to the air supply mode, it is determined that the air outlet direction of the damper meets the requirements. If the difference between the radiation temperature of the target part and the air temperature around the target part is not within the temperature difference range corresponding to the air supply mode, it is determined that the air outlet direction of the damper does not meet the requirements.

[0054] In some embodiments of the present application, the temperature sensor 40 collects temperature data of the driver and passenger of the vehicle 1 and transmits it to the electronic device 10, and then the electronic device 10 obtains the temperature data of the target part.

[0055] In some embodiments of the present application, if the air outlet direction of the air door meets the requirements, the electronic device 10 executes step S13.

[0056] In some embodiments of the present application, if the air outlet direction of the air door does not meet the requirements, the electronic device 10 executes step S14.

[0057] Step S13, adjusting the operating parameters of the air conditioner according to the thermal environment parameters of the driver and passengers and a preset thermal comfort model.

[0058] In some embodiments of the present application, adjusting the operating parameters of the air conditioner 20 according to the thermal environment parameters of the driver and the thermal comfort model preset includes: determining the thermal sensation of the driver and the occupant according to the thermal environment parameters of the driver and the thermal comfort model, for example, the thermal sensation includes but is not limited to very cold, cold, cool, slightly cool, neutral, slightly warm, warm, slightly hot, hot, very hot and other dimensions; judging whether the driver and the occupant are in a comfortable state according to the thermal sensation of the driver and the preset evaluation rules; if the driver and the occupant are not in a comfortable state, adjusting the operating parameters of the air conditioner 20 according to the thermal sensation; if the driver and the occupant are in a comfortable state, controlling the operating parameters of the air conditioner 20 to remain unchanged.

[0059] In some embodiments of the present application, the thermal environment parameters include temperature data and wind speed data of the target site.

[0060] In some embodiments of the present application, the operating parameters include a target air supply volume and a target temperature of the air conditioner 20 .

[0061] It should be noted that how to adjust the operating parameters of the air conditioner 20 according to the thermal environment parameters of the driver and the preset thermal comfort model will be described in the following. Figure 3 The steps shown are described in detail and will not be repeated here to avoid repetition.

[0062] Step S14, adjusting the air outlet direction of the damper according to the radiation temperature of the target part and the air temperature around the target part.

[0063] In some embodiments of the present application, for example, if the air supply mode is a blowing mode towards people, after a preset time interval (for example, 30 seconds), the radiation temperature of the target part (head) is still higher than the air temperature around the target part, then the air outlet direction of the air door is adjusted according to the position data of the target part, so that the air outlet direction of the air door is closer to the target part until the air outlet direction of the air door meets the requirements.

[0064] In the air-conditioning air supply control method of the above-mentioned embodiment, the target part is determined from at least one body part of the vehicle's driver and passenger according to the air supply mode of the air conditioner 20, and the air outlet direction of the air door of the air conditioner 20 is adjusted based on the air supply mode and the position data of the target part, which can ensure that the air outlet direction of the air door directly acts on the comfort zone of the driver and passenger, thereby improving the accuracy of the air supply of the air conditioner 20, meeting the comfort requirements of different users, and realizing personalized air supply. According to the temperature data of the target part, it is judged whether the air outlet direction of the air door meets the requirements, and when the air outlet direction of the air door meets the requirements, the operating parameters of the air conditioner 20 are dynamically adjusted according to the thermal environment parameters of the driver and passenger and the preset thermal comfort model, which can actively optimize the operating parameters of the air conditioner 20 in the dynamic scene changes in the vehicle, and reduce the frequency of manual adjustment of the air conditioner 20 by the user. Based on this, the present application improves the intelligence and accuracy of the air supply control of the air conditioner, especially in a dynamic environment, it can maintain the driver and passenger in a good comfort state in real time, provide the driver and passenger with a more comfortable, convenient and personalized air conditioner 20 use experience, avoid unnecessary energy waste, and improve the overall energy efficiency of the air conditioner 20.

[0065] See also Figure 3 , which is a detailed flow chart of step S13 in the air conditioning air supply control method provided in one embodiment of the present application.

[0066] This embodiment is a specific description of step S13 in the above embodiment, and further describes how to adjust the operating parameters of the air conditioner 20 according to the thermal environment parameters of the driver and the preset thermal comfort model. Specifically, it includes the following steps: Step S131 : determining the thermal sensation of the driver and occupants according to the thermal environment parameters and thermal comfort model of the driver and occupants.

[0067] In some embodiments of the present application, the thermal environment parameters include, but are not limited to, temperature data of the target site (eg, the radiation temperature of the target site and the air temperature around the target site) and wind speed data of the target site.

[0068] In some embodiments of the present application, the thermal comfort model includes but is not limited to one or more of the PMV-PPD model, the EHT model, the DTS / TS model, the Berkeley comfort model and the like.

[0069] In some embodiments of the present application, thermal sensation includes but is not limited to dimensions such as very cold, cold, cool, slightly cool, neutral, slightly warm, warm, slightly hot, hot, and very hot.

[0070] It should be noted that determining the thermal sensation of the driver and occupants based on the thermal environment parameters and thermal comfort model of the driver and occupants is a relatively common technology and will not be described in detail here.

[0071] In some embodiments of the present application, after the gear of the blower of the air conditioner 20 is set, the actual wind speed of the air outlet of the air door of the air conditioner 20 is known, and then the electronic device 10 can calculate the radiant wind speed of the target part based on the actual wind speed of the air outlet of the air door and the distance from the air outlet of the air door to the target part. The shapes of the air outlets of the air door are different, and the calculation formulas are also different.

[0072] For example, if the air outlet of the air door of the air conditioner 20 is in a circular shape, the calculation formula of the radiation wind speed at the target location is as follows: in, is the radiation wind speed at the target location, is the actual wind speed at the air outlet of the damper, is the turbulence coefficient, is the distance from the air outlet of the damper to the target part, is the radius of the air outlet of the air door of the air conditioner 20.

[0073] In some embodiments of the present application, the visual sensor 30 can capture the position of the target part, and calculate the distance between the visual sensor 30 and the target part in combination with the signal reflected by the target part. Since the position of the visual sensor 30 is fixed and the position of the damper is also fixed, the distance between the visual sensor 30 and the damper can be calculated based on the position of the visual sensor 30 and the position of the damper. Finally, the distance from the damper to the target part can be calculated based on the distance between the visual sensor 30 and the target part and the distance between the visual sensor 30 and the damper.

[0074] In other embodiments, the vehicle 1 may further include a laser radar, which is installed at the air door, and collects the distance from the air door to the target part through the laser radar.

[0075] Step S132, judging whether the driver and occupant are in a comfortable state according to the thermal sensation of the driver and occupant and preset evaluation rules.

[0076] In some embodiments of the present application, the preset evaluation rules include but are not limited to: if the thermal sensation of the driver and the occupant is neutral, it is determined that the driver and the occupant are in a comfortable state; if the thermal sensation of the driver and the occupant is cold or hot, it is determined that the driver and the occupant are not in a comfortable state.

[0077] In some embodiments of the present application, if the driver and passenger are not in a comfortable state, the electronic device 10 executes step S133.

[0078] In some embodiments of the present application, if the driver and passenger are in a comfortable state, the electronic device 10 executes step S134.

[0079] Step S133, adjusting the operating parameters of the air conditioner according to the thermal sensation.

[0080] In some embodiments of the present application, the operating parameters include the target air volume and target temperature of the air conditioner 20. For example, if the thermal sensation of the driver and passenger is hot, the target air volume of the air conditioner 20 is increased and the target temperature of the air conditioner 20 is decreased.

[0081] Step S134, controlling the operating parameters of the air conditioner to remain unchanged.

[0082] In some embodiments of the present application, the electronic device 10 can maintain the operating parameters of the air conditioner 20 by controlling components such as a compressor and a heater core of the air conditioner 20 .

[0083] In the above embodiment, by real-time monitoring of the thermal environment parameters of the driver and passengers, calculating the thermal sensation of the driver and passengers in combination with the thermal comfort model, and accurately adjusting the operating parameters of the air conditioner 20 according to the thermal sensation, it is possible to ensure that the driver and passengers are always in a comfortable thermal environment, significantly improve the comfort experience of the driver and passengers, reduce fatigue caused by temperature discomfort, avoid unnecessary energy waste, and reduce energy consumption.

[0089] Specifically, the visual sensor 30 collects image data of the driver and passengers of the vehicle 1 and transmits it to the electronic device 10, which then uses image recognition technology (such as an algorithm based on key point detection, a semantic segmentation technology based on deep learning, an image recognition technology based on multimodal fusion, etc.) to analyze and identify the image data, thereby identifying at least one body part of the driver and passenger, and determining the position data of each body part in the at least one body part.

[0090] In other embodiments, the visual sensor 30 has the function of identifying at least one body part of the driver and passenger based on the collected image data and determining the position data of each body part.

[0091] In some embodiments of the present application, the electronic device 10 pre-configures the air supply mode of the air conditioner 20, such as a blowing mode towards people, a blowing mode away from people, an up and down sweeping mode, a left and right sweeping mode, an intelligent air supply mode, etc. The driver and passengers can select the air supply mode that meets their personal needs through the soft buttons on the vehicle-mounted touch interface.

[0092] Specifically, the target part is determined from at least one body part of the vehicle occupant according to the air supply mode of the air conditioner 20, including: if the air supply mode is a blowing mode towards people, the target part includes the head; if the air supply mode is a blowing mode avoiding people, the target part includes at least one body part; if the air supply mode is an up and down sweeping mode, the target part includes the head and abdomen; if the air supply mode is a left and right sweeping mode, the target part includes the left arm and the right arm.

[0093] In other embodiments, if the air supply mode of the air conditioner 20 is an intelligent air supply mode, the electronic device 10 can intelligently determine the air supply mode according to the thermal sensation of the driver and passenger. The thermal sensation includes but is not limited to very cold, cold, cool, slightly cool, neutral, slightly warm, warm, slightly hot, hot, and very hot. For example, if the thermal sensation of the driver and passenger is hot or very hot, the blowing mode on the person needs to be adopted to achieve rapid cooling; if the thermal sensation of the driver and passenger is slightly hot, the left and right sweeping mode or the up and down sweeping mode can be adopted to achieve cooling; if the thermal sensation of the driver and passenger is neutral, the avoiding blowing mode can be adopted.

[0094] The first adjustment module 120 is used to adjust the air outlet direction of the air door of the air conditioner 20 based on the air supply mode and the position data of the target part.

[0095] Specifically, adjusting the air outlet direction of the air door of the air conditioner 20 based on the air supply mode and the position data of the target part includes: if the air supply mode is the blowing mode towards people, the air outlet direction of the air door is controlled to be toward the target part based on the position data of the target part; if the air supply mode is the blowing mode away from people, the air outlet direction of the air door is controlled to avoid the target part based on the position data of the target part; if the air supply mode is the up and down sweeping mode, the air outlet direction of the air door is controlled to reciprocate up and down between the target parts based on the position data of the target part; if the air supply mode of the air conditioner 20 is the left and right sweeping mode, the air outlet direction of the air door is controlled to reciprocate left and right between the target parts based on the position data of the target part.

[0096] The wind direction determination module 130 is used to determine whether the air outlet direction of the damper meets the requirements according to the temperature data of the target part.

[0097] In some embodiments of the present application, the temperature data of the target site includes, but is not limited to, the radiation temperature of the target site and the air temperature around the target site.

[0098] In some embodiments of the present application, the temperature of the air outlet of the damper is relatively low, generally at 5-15°C. After the airflow is blown out of the air outlet, it will gradually rise due to the "entrainment effect", that is, the farther away from the air outlet, the higher the air temperature will be. For example, if the air supply mode is the blowing mode to the person, the wind blows towards the head, the radiation temperature of the head will be lower than the air temperature around the head, and there will be a large temperature gradient, that is, there will be a large difference between the radiation temperature of the head and the air temperature around the head.

[0099] Specifically, the specific steps of judging whether the air outlet direction of the damper meets the requirements according to the temperature data of the target part include: obtaining the temperature data of the target part, wherein the temperature data includes the radiation temperature of the target part and the air temperature around the target part. If the difference between the radiation temperature of the target part and the air temperature around the target part is within the temperature difference range corresponding to the air supply mode, it is determined that the air outlet direction of the damper meets the requirements. If the difference between the radiation temperature of the target part and the air temperature around the target part is not within the temperature difference range corresponding to the air supply mode, it is determined that the air outlet direction of the damper does not meet the requirements.

[0100] In some embodiments of the present application, the temperature sensor 40 collects temperature data of the driver and passenger of the vehicle 1 and transmits it to the electronic device 10, and then the electronic device 10 obtains the temperature data of the target part.

[0101] The second adjustment module 140 is used to adjust the operating parameters of the air conditioner 20 according to the thermal environment parameters of the driver and passengers and a preset thermal comfort model if the air outlet direction of the air door meets the requirements.

[0102] In some embodiments of the present application, adjusting the operating parameters of the air conditioner 20 according to the thermal environment parameters of the driver and the thermal comfort model preset includes: determining the thermal sensation of the driver and the occupant according to the thermal environment parameters of the driver and the thermal comfort model, for example, the thermal sensation includes but is not limited to very cold, cold, cool, slightly cool, neutral, slightly warm, warm, slightly hot, hot, very hot and other dimensions; judging whether the driver and the occupant are in a comfortable state according to the thermal sensation of the driver and the preset evaluation rules; if the driver and the occupant are not in a comfortable state, adjusting the operating parameters of the air conditioner 20 according to the thermal sensation; if the driver and the occupant are in a comfortable state, controlling the operating parameters of the air conditioner 20 to remain unchanged.

[0103] In some embodiments of the present application, the thermal environment parameters include temperature data and wind speed data of the target site.

[0104] In some embodiments of the present application, the operating parameters include a target air supply volume and a target temperature of the air conditioner 20 .

According to the temperature data of the target part, it is judged whether the air outlet direction of the air door meets the requirements, and when the air outlet direction of the air door meets the requirements, the operating parameters of the air-conditioning 20 are dynamically adjusted according to the thermal environment parameters of the driver and passenger and the preset thermal comfort model, and the operating parameters of the air-conditioning 20 can be actively optimized in the dynamic scene changes in the vehicle, reducing the frequency of manual adjustment of the air-conditioning 20 by the user. Based on this, the present application improves the intelligence and accuracy of the air-conditioning air supply control, especially in a dynamic environment, it can maintain the driver and passenger in a good comfort state in real time, provide the driver and passenger with a more comfortable, convenient and personalized air-conditioning 20 use experience, avoid unnecessary energy waste, and improve the overall energy efficiency of the air-conditioning 20.
