[0002] With the rapid development of automobile intelligent cockpit technology, the design of automobile air conditioner air outlet is gradually changing from traditional mechanical air outlet to electronic air outlet. The traditional mechanical air outlet usually changes the air direction by manually adjusting the dial, which is relatively cumbersome and has safety hazards during driving. The electronic air outlet is driven by a motor, and users can adjust the air direction up, down, left and right through soft keys on the vehicle touch interface.

[0003] However, in different scenarios, the air direction and temperature requirements of the driver and passengers vary significantly. The existing air conditioner air outlet adjustment scheme only supports preset direction mode switching, and cannot achieve effective active adjustment in a dynamic environment, resulting in poor air supply accuracy of the automobile air conditioner, seriously affecting the comfort, and being difficult to meet the personalized and intelligent comfort requirements of users. SUMMARY

[0004] In view of the above, it is necessary to provide an air conditioner air supply control method, device, equipment and vehicle to solve the technical problem that the existing air conditioner air outlet adjustment scheme cannot achieve effective active adjustment in a dynamic environment, resulting in poor air supply accuracy of the automobile air conditioner, seriously affecting the comfort, and being difficult to meet the personalized and intelligent comfort requirements of users.

[0006] In the air conditioning air supply control method of the above embodiments, a target part is determined from at least one body part of the vehicle's occupants based on the air supply mode.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0040] Please see Figure 1 This is a schematic diagram illustrating an application scenario of an air conditioning air supply control method provided in an embodiment of this application.

[0041] The air conditioning air supply control method provided in this application embodiment can be applied to vehicle 1. Vehicle 1 includes electronic device 10. Electronic device 10 may be the electronic control unit (ECU) of air conditioning 20.

[0042] In some embodiments of this application, the air conditioning air supply control method provided in this application can be applied to one or at least one electronic device 10. The electronic device 10 is a device that can automatically perform numerical calculations and / or information processing according to pre-set or stored instructions. Its hardware includes, but is not limited to, microprocessors, application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), digital signal processors (DSPs), embedded devices, etc.

[0043] Specifically, the electronic device 10 is used to: determine a target part from at least one body part of the vehicle's occupants according to the air supply mode of the air conditioner 20; adjust the air outlet direction of the air damper of the air conditioner 20 based on the air supply mode and the position data of the target part; determine whether the air outlet direction of the air damper meets the requirements based on the temperature data of the target part; and if the air outlet direction of the air damper meets the requirements, adjust the operating parameters of the air conditioner 20 according to the thermal environment parameters of the occupants and the preset thermal comfort model.

[0044] In some embodiments of this application, the damper can be an electrically controlled damper or a magnetically controlled damper, and this application does not limit it in this regard.

[0045] In other embodiments, the electronic device 10 may also be an on-board device of the vehicle 1, such as a Body Control Module (BCM) or a Vehicle Control Unit (VCU), etc., and this application does not limit it in this regard.

[0046] In some embodiments of this application, the electronic device 10 can be communicatively connected to devices such as desktop computers, laptops, handheld computers, and cloud servers.

[0047] In some embodiments of this application, the electronic device 10 can interact with the user via a keyboard, mouse, remote control, touchpad, or voice control device.

[0048] In some embodiments of this application, the electronic device 10 may further include network devices and / or client devices. These network devices include, but are not limited to, a single network server, a server group consisting of at least one network server, or a cloud server based on cloud computing consisting of a large number of hosts or network servers.

[0049] In some embodiments of this application, the network where the electronic device 10 is located includes, but is not limited to, the Internet, wide area network, metropolitan area network, local area network, virtual private network (VPN), etc.

[0050] In some embodiments of this application, vehicle 1 further includes an air conditioner 20, a vision sensor 30, and a temperature sensor 40. Electronic device 10 is communicatively connected to the vision sensor 30 and the temperature sensor 40. Specifically, the vision sensor 30 and the temperature sensor 40 are mounted on the inside of the A-pillar of vehicle 1 or on the rearview mirror. The vision sensor 30 includes, but is not limited to, a 3D camera, used to collect image data of the passenger compartment of vehicle 1. The temperature sensor 40 includes, but is not limited to, an infrared temperature sensor 40, used to collect temperature data of the occupants in the passenger compartment of vehicle 1.

[0051] Please see Figure 2 This is a schematic diagram of the steps of an air conditioning air supply control method provided in an embodiment of this application.

[0052] Specifically, the air conditioning air supply control method includes the following steps. Depending on different needs, the order of some steps in the flowchart can be changed, and some steps can be omitted.

[0053] Step S10: Determine the target part from at least one body part of the vehicle's occupants according to the air conditioning's air delivery mode.

[0054] In some embodiments of this application, at least one body part of the driver or passenger includes the head, abdomen, left arm, and right arm.

[0055] Specifically, the vision sensor 30 collects image data of the driver and passengers of the vehicle 1 and transmits it to the electronic device 10. The electronic device 10 then uses image recognition technology (such as key point detection-based algorithms, deep learning-based semantic segmentation technology, multimodal fusion-based image recognition technology, etc.) to analyze and identify the image data, thereby identifying at least one human body part of the driver and passengers and determining the position data of each human body part in the at least one human body part.

[0056] In other embodiments, the vision sensor 30 has the function of identifying at least one body part of the driver or passenger based on the acquired image data and determining the position data of each body part.

[0057] In some embodiments of this application, the electronic device 10 is pre-configured with the air supply mode of the air conditioner 20, such as the human-facing mode, the human-avoiding mode, the up-and-down sweeping mode, the left-and-right sweeping mode, the 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 touch interface.

[0058] Specifically, determining the target body part from at least one body part of the vehicle's occupants based on the air supply mode of the air conditioner 20 includes: if the air supply mode is a direct blowing mode, the target body part includes the head; if the air supply mode is an avoid-blowing mode, the target body part includes at least one body part; if the air supply mode is an up-and-down sweeping mode, the target body part includes the head and abdomen; if the air supply mode is a left-and-right sweeping mode, the target body part includes the left arm and right arm.

[0059] In other embodiments, if the air conditioning 20's air delivery mode is an intelligent air delivery mode, the electronic device 10 can intelligently determine the air delivery mode based on the thermal sensation of the occupants. 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. For example, if the occupants feel hot or very hot, a direct-blowing mode should be used to achieve rapid cooling; if the occupants feel slightly hot, a left-right or up-down airflow mode can be used to achieve cooling; if the occupants feel neutral, an avoidance-blowing mode can be used.

[0060] It should be noted that how to calculate thermal sensation will be discussed later. Figure 3 Step S131 is described in detail, and will not be repeated here to avoid repetition.

[0061] Step S11: Adjust the airflow direction of the air conditioner damper based on the air supply mode and the location data of the target location.

[0062] Specifically, adjusting the airflow direction of the air damper of the air conditioner 20 based on the air supply mode and the location data of the target location includes: if the air supply mode is a direct airflow mode, controlling the air damper to blow air towards the target location based on the location data of the target location; if the air supply mode is an indirect airflow mode, controlling the air damper to blow air away from the target location based on the location data of the target location; if the air supply mode is an up-and-down swing mode, controlling the air damper to swing air up and down between the target locations based on the location data of the target location; if the air supply mode of the air conditioner 20 is a left-and-right swing mode, controlling the air damper to swing air left and right between the target locations based on the location data of the target location.

[0063] Step S12: Determine whether the air outlet direction of the damper meets the requirements based on the temperature data of the target location.

[0064] In some embodiments of this application, the temperature data of the target location includes, but is not limited to, the radiation temperature of the target location and the air temperature surrounding the target location.

[0065] In some embodiments of this application, the temperature of the air outlet of the damper is relatively low, generally between 5 and 15°C. After the airflow is blown out of the outlet, it gradually rises due to the "entrainment effect," meaning that the further away from the outlet, the higher the air temperature. For example, if the air supply mode is a direct-to-person blowing mode, the air blows towards the head, and the radiant temperature of the head is lower than the air temperature around the head, resulting in a large temperature gradient, i.e., a significant difference between the radiant temperature of the head and the air temperature around the head.

[0066] Specifically, the steps for determining whether the air outlet direction of the damper meets the requirements based on the temperature data of the target location include: acquiring the temperature data of the target location, which includes the radiant temperature of the target location and the air temperature surrounding the target location. If the difference between the radiant temperature of the target location and the air temperature surrounding the target location is within the temperature difference range corresponding to the air supply mode, the air outlet direction of the damper is determined to meet the requirements. If the difference between the radiant temperature of the target location and the air temperature surrounding the target location is not within the temperature difference range corresponding to the air supply mode, the air outlet direction of the damper is determined to not meet the requirements.

[0067] In some embodiments of this application, the temperature sensor 40 collects the temperature data of the occupants of the vehicle 1 and transmits it to the electronic device 10, thereby the electronic device 10 obtains the temperature data of the target area.

[0068] In some embodiments of this application, if the air outlet direction of the damper meets the requirements, the electronic device 10 executes step S13.

[0069] In some embodiments of this application, if the air outlet direction of the damper does not meet the requirements, the electronic device 10 executes step S14.

[0070] Step S13: Adjust the operating parameters of the air conditioner according to the thermal environment parameters of the driver and passengers and the preset thermal comfort model.

[0071] In some embodiments of this application, adjusting 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 includes: determining the thermal sensation of the driver and passengers according to the thermal environment parameters of the driver and passengers and the thermal comfort model, for example, 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; judging whether the driver and passengers are in a comfortable state according to the thermal sensation of the driver and passengers and preset evaluation rules; if the driver and passengers are not in a comfortable state, adjusting the operating parameters of the air conditioner 20 according to the thermal sensation; if the driver and passengers are in a comfortable state, controlling the operating parameters of the air conditioner 20 to remain unchanged.

[0072] In some embodiments of this application, thermal environment parameters include temperature data and wind speed data of the target location.

[0073] In some embodiments of this application, the operating parameters include the target air volume and target temperature of the air conditioner 20.

[0074] It should be noted that details on how to adjust the operating parameters of the air conditioner 20 based on the thermal environment parameters of the occupants and the preset thermal comfort model will be provided later. Figure 3 The steps shown are described in detail, and will not be repeated here to avoid repetition.

[0075] Step S14: Adjust the air outlet direction of the damper according to the radiation temperature of the target area and the air temperature around the target area.

[0076] In some embodiments of this application, for example, if the air supply mode is a blow-on mode, and after a preset time interval (e.g., 30 seconds), the radiant temperature of the target part (head) is still higher than the air temperature around the target part, then the air outlet direction of the damper is adjusted according to the location data of the target part, so that the air outlet direction of the damper is closer to the target part, until the air outlet direction of the damper meets the requirements.

[0077] In the air conditioning air supply control method of the above embodiments, a target part is determined from at least one body part of the vehicle's occupants based on the air supply mode of the air conditioner 20. The air outlet direction of the air conditioner 20 is adjusted based on the air supply mode and the position data of the target part. This ensures that the air outlet direction directly affects the comfort area of ​​the occupants, thereby improving the accuracy of the air supply of the air conditioner 20, meeting the comfort needs of different users, and achieving personalized air supply. The air outlet direction is determined based on the temperature data of the target part to determine if it meets the requirements. If it does, the operating parameters of the air conditioner 20 are dynamically adjusted based on the thermal environment parameters of the occupants and a preset thermal comfort model. This proactively optimizes the operating parameters of the air conditioner 20 in dynamic changes within the vehicle, reducing the frequency of manual adjustments by the user. Based on this, this application improves the intelligence and accuracy of air conditioning air supply control, especially in dynamic environments, maintaining a good comfort state for occupants in real time, providing a more comfortable, convenient, and personalized air conditioning 20 user experience, avoiding unnecessary energy waste, and improving the overall energy efficiency of the air conditioner 20.

[0078] Please see Figure 3 This is a detailed flowchart of step S13 in an air conditioning air supply control method provided in an embodiment of this application.

[0079] This embodiment is a detailed explanation of step S13 in the aforementioned embodiment, further illustrating how to adjust the operating parameters of the air conditioner 20 according to the thermal environment parameters of the occupants and the preset thermal comfort model. Specifically, it includes the following steps:

[0080] Step S131: Determine the thermal sensation of the driver and passengers based on the thermal environment parameters and thermal comfort model.

[0081] In some embodiments of this application, thermal environment parameters include, but are not limited to, temperature data of the target location (e.g., radiation temperature of the target location and air temperature around the target location) and wind speed data of the target location.

[0082] In some embodiments of this application, the thermal comfort model includes, but is not limited to, one or more of the following models: PMV-PPD model, EHT model, DTS / TS model, Berkeley comfort model, etc.

[0083] In some embodiments of this application, thermal sensation includes, but is not limited to, dimensions such as very cold, cold, cool, slightly cool, neutral, slightly warm, warm, warm, hot, and very hot.

[0084] It should be noted that determining the thermal sensation of drivers and passengers based on thermal environment parameters and thermal comfort models is a relatively common technique, and will not be elaborated upon here.

[0085] In some embodiments of this application, after the blower speed of the air conditioner 20 is set, the actual wind speed at the air outlet of the air conditioner 20 is known. Therefore, the electronic device 10 can calculate the radiant wind speed at the target location based on the actual wind speed at the air outlet and the distance from the air outlet to the target location. The calculation formula varies depending on the shape of the air outlet.

[0086] For example, if the air outlet of the air conditioner 20 is circular, the formula for calculating the radiant wind speed at the target location is as follows:

[0087]

[0088] in, The radiation wind speed at the target location. This represents the actual air velocity at the outlet of the damper. The turbulence coefficient is...

[0089] This refers to the distance from the air outlet of the damper to the target area. The radius of the air outlet of the air conditioner 20's damper.

[0090] In some embodiments of this application, the vision sensor 30 can capture the position of the target area and calculate the distance between the vision sensor 30 and the target area by combining the signal reflected back from the target area. Since the position of the vision sensor 30 is fixed and the position of the damper is also fixed, the distance between the vision sensor 30 and the damper can be calculated based on the positions of the vision sensor 30 and the damper. Finally, the distance from the damper to the target area can be calculated based on the distance between the vision sensor 30 and the target area and the distance between the vision sensor 30 and the damper.

[0091] In other embodiments, vehicle 1 may also include a lidar. The lidar is mounted at the vent. The lidar acquires the distance from the vent to the target location.

[0092] Step S132: Determine whether the driver and passengers are in a comfortable state based on the thermal sensation of the driver and passengers and the preset evaluation rules.

[0093] In some embodiments of this application, the preset evaluation rules include, but are not limited to, determining that the driver or passenger is in a comfortable state if the driver or passenger's thermal sensation is neutral, and determining that the driver or passenger is not in a comfortable state if the driver or passenger's thermal sensation is cold or hot.

[0094] In some embodiments of this application, if the driver or passenger is not in a comfortable state, the electronic device 10 executes step S133.

[0095] In some embodiments of this application, if the driver or passenger is in a comfortable state, the electronic device 10 executes step S134.

[0096] Step S133: Adjust the operating parameters of the air conditioner according to the heat sensation.

[0097] In some embodiments of this application, the operating parameters include the target air volume and target temperature of the air conditioner 20. For example, if the occupants feel hot, the target air volume of the air conditioner 20 is increased, and the target temperature of the air conditioner 20 is decreased.

[0098] Step S134: Keep the operating parameters of the air conditioner unchanged.

[0099] In some embodiments of this application, the electronic device 10 can maintain the operating parameters of the air conditioner 20 by controlling components such as the compressor and heater core of the air conditioner 20.

[0100] In the above embodiments, by monitoring the thermal environment parameters of drivers and passengers in real time, calculating the thermal sensation of drivers and passengers using a thermal comfort model, and precisely adjusting the operating parameters of the air conditioner 20 according to the thermal sensation, it is possible to ensure that drivers and passengers are always in a comfortable thermal environment, significantly improving the comfort experience of drivers and passengers, reducing fatigue caused by temperature discomfort, avoiding unnecessary energy waste, and reducing energy consumption.

[0101] Please see Figure 4 This is a schematic diagram of the functional modules of an air conditioning air supply control device 100 provided in an embodiment of this application.

[0102] In this embodiment, based on the above... Figure 2Using the same concept as the air conditioning air supply control method in the illustrated embodiment, this application also provides an air conditioning air supply control device 100, which can be used to execute the above-described air conditioning air supply control method. For ease of explanation, the schematic diagram of the air conditioning air supply control device 100 embodiment only shows the parts related to the embodiments of this application. Those skilled in the art will understand that the illustrated structure does not constitute a limitation on the air conditioning air supply control device 100, and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0103] Specifically, the air conditioning air supply control device 100 provided in this application embodiment includes a location determination module 110, a first adjustment module 120, a wind direction judgment module 130, and a second adjustment module 140.

[0104] The part determination module 110 is used to determine the target part from at least one body part of the driver and passengers of the vehicle according to the air supply mode of the air conditioner 20.

[0105] In some embodiments of this application, at least one body part of the driver or passenger includes the head, abdomen, left arm, and right arm.

[0106] Specifically, the vision sensor 30 collects image data of the driver and passengers of the vehicle 1 and transmits it to the electronic device 10. The electronic device 10 then uses image recognition technology (such as key point detection-based algorithms, deep learning-based semantic segmentation technology, multimodal fusion-based image recognition technology, etc.) to analyze and identify the image data, thereby identifying at least one human body part of the driver and passengers and determining the position data of each human body part in the at least one human body part.

[0107] In other embodiments, the vision sensor 30 has the function of identifying at least one body part of the driver or passenger based on the acquired image data and determining the position data of each body part.

[0108] In some embodiments of this application, the electronic device 10 is pre-configured with the air supply mode of the air conditioner 20, such as the human-facing mode, the human-avoiding mode, the up-and-down sweeping mode, the left-and-right sweeping mode, the 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 touch interface.

[0109] Specifically, determining the target body part from at least one body part of the vehicle's occupants based on the air supply mode of the air conditioner 20 includes: if the air supply mode is a direct blowing mode, the target body part includes the head; if the air supply mode is an avoid-blowing mode, the target body part includes at least one body part; if the air supply mode is an up-and-down sweeping mode, the target body part includes the head and abdomen; if the air supply mode is a left-and-right sweeping mode, the target body part includes the left arm and right arm.

[0110] In other embodiments, if the air conditioning 20's air delivery mode is an intelligent air delivery mode, the electronic device 10 can intelligently determine the air delivery mode based on the thermal sensation of the occupants. 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. For example, if the occupants feel hot or very hot, a direct-blowing mode should be used to achieve rapid cooling; if the occupants feel slightly hot, a left-right or up-down airflow mode can be used to achieve cooling; if the occupants feel neutral, an avoidance-blowing mode can be used.

[0111] The first adjustment module 120 is used to adjust the air outlet direction of the air damper of the air conditioner 20 based on the air supply mode and the location data of the target location.

[0112] Specifically, adjusting the airflow direction of the air damper of the air conditioner 20 based on the air supply mode and the location data of the target location includes: if the air supply mode is a direct airflow mode, controlling the air damper to blow air towards the target location based on the location data of the target location; if the air supply mode is an indirect airflow mode, controlling the air damper to blow air away from the target location based on the location data of the target location; if the air supply mode is an up-and-down swing mode, controlling the air damper to swing air up and down between the target locations based on the location data of the target location; if the air supply mode of the air conditioner 20 is a left-and-right swing mode, controlling the air damper to swing air left and right between the target locations based on the location data of the target location.

[0113] The wind direction judgment module 130 is used to determine whether the air outlet direction of the damper meets the requirements based on the temperature data of the target location.

[0114] In some embodiments of this application, the temperature data of the target location includes, but is not limited to, the radiation temperature of the target location and the air temperature surrounding the target location.

[0115] In some embodiments of this application, the temperature of the air outlet of the damper is relatively low, generally between 5 and 15°C. After the airflow is blown out of the outlet, it gradually rises due to the "entrainment effect," meaning that the further away from the outlet, the higher the air temperature. For example, if the air supply mode is a direct-to-person blowing mode, the air blows towards the head, and the radiant temperature of the head is lower than the air temperature around the head, resulting in a large temperature gradient, i.e., a significant difference between the radiant temperature of the head and the air temperature around the head.

[0116] Specifically, the steps for determining whether the air outlet direction of the damper meets the requirements based on the temperature data of the target location include: acquiring the temperature data of the target location, which includes the radiant temperature of the target location and the air temperature surrounding the target location. If the difference between the radiant temperature of the target location and the air temperature surrounding the target location is within the temperature difference range corresponding to the air supply mode, the air outlet direction of the damper is determined to meet the requirements. If the difference between the radiant temperature of the target location and the air temperature surrounding the target location is not within the temperature difference range corresponding to the air supply mode, the air outlet direction of the damper is determined to not meet the requirements.

[0117] In some embodiments of this application, the temperature sensor 40 collects the temperature data of the occupants of the vehicle 1 and transmits it to the electronic device 10, thereby the electronic device 10 obtains the temperature data of the target area.

[0118] 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 the preset thermal comfort model if the air outlet direction of the damper meets the requirements.

[0119] In some embodiments of this application, adjusting 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 includes: determining the thermal sensation of the driver and passengers according to the thermal environment parameters of the driver and passengers and the thermal comfort model, for example, 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; judging whether the driver and passengers are in a comfortable state according to the thermal sensation of the driver and passengers and preset evaluation rules; if the driver and passengers are not in a comfortable state, adjusting the operating parameters of the air conditioner 20 according to the thermal sensation; if the driver and passengers are in a comfortable state, controlling the operating parameters of the air conditioner 20 to remain unchanged.

[0120] In some embodiments of this application, thermal environment parameters include temperature data and wind speed data of the target location.

[0121] In some embodiments of this application, the operating parameters include the target air volume and target temperature of the air conditioner 20.

[0122] In the air conditioning air supply control device 100 of the above embodiment, a target part is determined from at least one body part of the vehicle's occupants based on the air supply mode of the air conditioner 20. The air outlet direction of the air conditioner 20 is adjusted based on the air supply mode and the position data of the target part. This ensures that the air outlet direction directly affects the comfort area of ​​the occupants, thereby improving the accuracy of the air supply of the air conditioner 20, meeting the comfort needs of different users, and achieving personalized air supply. The air outlet direction is determined based on the temperature data of the target part to determine if it meets the requirements. If it does, the operating parameters of the air conditioner 20 are dynamically adjusted based on the thermal environment parameters of the occupants and a preset thermal comfort model. This proactively optimizes the operating parameters of the air conditioner 20 in dynamic changes within the vehicle, reducing the frequency of manual adjustments by the user. Based on this, this application improves the intelligence and accuracy of air conditioning air supply control, especially in dynamic environments, maintaining a good comfort state for occupants in real time, providing a more comfortable, convenient, and personalized air conditioning 20 user experience, avoiding unnecessary energy waste, and improving the overall energy efficiency of the air conditioner 20.
