[0074] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0075] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0076] Example 1

[0077] Please refer to Figure 1 , Figure 1 This embodiment provides a flowchart illustrating a vehicle air conditioning control method. The vehicle air conditioning control method includes:

[0078] S101. Construct the vehicle air conditioning control framework.

[0079] S102. Obtain the set of usage scenarios for the vehicle's air conditioning system.

[0080] S103. Based on the vehicle air conditioning control framework and usage scenario set, obtain the vehicle air conditioning control strategy set.

[0081] S104. Determine the target control strategy based on the vehicle air conditioning control strategy set.

[0082] In this embodiment, the target control strategy includes air outlet area parameters, temperature compensation parameters corresponding to the air outlet area parameters, wind speed compensation parameters corresponding to the air outlet area parameters, and residence time compensation parameters corresponding to the air outlet area parameters.

[0083] S105. Control the vehicle air conditioner to perform corresponding operations according to the target control strategy.

[0084] In this embodiment, the method addresses the issue of poor comfort under single flow field control. Specifically, since the cooling / heating effect of air conditioning is mainly achieved by delivering cold / hot air, whether the airflow reaches the human body has a significant impact on a person's temperature perception. Therefore, when the airflow direction switches from airflow to direct airflow, the perceived temperature can vary greatly even at the same outlet air temperature. Furthermore, some vehicles with panoramic sunroofs experience high heat loads from solar radiation, resulting in significant temperature stratification in the vertical areas of the interior. If the control strategy for the electronic air vents only considers changes in airflow direction without compensating for outlet air temperature, it will negatively impact comfort. To address this issue, this method employs multi-field coordinated control of temperature and flow fields to create diverse airflow experiences, enhancing the vehicle's unique characteristics and competitiveness.

[0085] In this embodiment, the subject executing the method can be a computing device such as a computer or server, and no limitation is made in this embodiment.

[0086] In this embodiment, the subject executing the method can also be a smart device such as a smartphone or tablet, and no limitation is made in this embodiment.

[0087] It is evident that implementing the vehicle air conditioning control method described in this embodiment can solve the problem of poor comfort experience under single flow field control, and is conducive to improving the airflow experience and driving comfort of the vehicle air conditioning.

[0093] S203. Divide the air outlet coverage area according to the human body outline to obtain a set of air outlet sub-regions.

[0094] In this embodiment, the air outlet area set includes at least the air blowing area on both sides of the head, the head boundary area, the head direct blowing area, the air blowing area on both sides of the chest, the arm boundary area, the chest direct blowing area, the air blowing area on both sides of the abdomen, the abdomen boundary area, and the abdomen direct blowing area.

[0095] Please refer to Figure 7 1 is the air blowing area on both sides of the head, 2 is the boundary area of ​​the head, 3 is the direct air blowing area of ​​the head, 4 is the air blowing area on both sides of the chest, 5 is the boundary area of ​​the arms, 6 is the direct air blowing area of ​​the chest, 7 is the air blowing area on both sides of the abdomen, 8 is the boundary area of ​​the abdomen, and 9 is the direct air blowing area of ​​the abdomen.

[0096] S204. Obtain the temperature and wind speed compensation table based on the set of air outlet sub-regions.

[0097] In this embodiment, considering that different parts of the human body, such as the head, abdomen, and chest, have different sensitivities to wind temperature and wind speed, such as the head and abdomen being more sensitive to temperature while the chest is relatively less sensitive, the wind temperature, wind speed, and dwell time in different areas are compensated and controlled accordingly according to Table 1.

[0098] Table 1. Temperature and wind speed compensation for different regions

[0100] In this embodiment, all of the above values ​​can be determined by calibration, and different calibration values ​​can correspond to different wind sensation experiences.

[0109] In this embodiment, the target control strategy includes air outlet area parameters, temperature compensation parameters corresponding to the air outlet area parameters, wind speed compensation parameters corresponding to the air outlet area parameters, and residence time compensation parameters corresponding to the air outlet area parameters.

[0110] For example, this method can use an in-vehicle camera to identify the dilation of capillaries on an occupant's face, thereby determining whether the occupant is currently in a relatively hot state. Based on this, the method uses a trajectory of 2 left → 3 → 2 right → 6 → 8 left → 5 left → 6 → 5 right → 8 right → 6 → 2 left… to sweep the air, and employs a set of negative temperature compensation, positive wind speed compensation, and dwell time compensation. A set of recommended parameters is shown in Table 2.

[0137] In this embodiment, for vehicles with panoramic sunroofs, the high heat load from solar radiation results in significant temperature stratification in the vertical areas of the vehicle interior.

[0149] Example 4

[0150] Please refer to Figure 4 , Figure 4 This embodiment provides a flowchart illustrating a vehicle air conditioning control method. The vehicle air conditioning control method includes:

[0151] S401. Determine the air vent coverage area of ​​the target vehicle's air conditioning system.

[0163] For example, when the interior temperature reaches the set temperature (|T_incar-Tset|≤calibrated threshold), it is determined that the interior has reached the steady-state comfort zone. To further improve comfort and avoid the unpleasant experience of direct cold air blowing, the airflow direction is set to a windless mode, that is, avoiding the human body area and using indirect airflow cooling to maintain the comfort of the driver and passengers; at the same time, to maintain the uniformity of the interior temperature, the electronic air outlets are controlled to sweep air along the trajectory of 1 left→4→7→6→1 right→4→7→6→1 left→4→7…, and the compensation table is shown in Table 4.

[0164] Table 4. Wind and Temperature Compensation Table for Target Control Strategies When Comfort Levels are High

[0165]

[0166] Meanwhile, based on vehicle positioning and user research, this method can design scenario-specific airflow trajectories and compensations for air temperature, wind speed, and dwell time to create different wind sensation experiences.

[0167] For example, the sweeping trajectory corresponding to "cool breeze in the mountain stream" is 7 left → 5 left → 4 left → 5 left → 6 → 2 right → 3 → 2 left → 6 → 5 right → 4 right → 5 right → 7 right → 8 right → 9 → 8 left → 7 left...
