[0047] The present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the scope of the present application.

[0048] For ease of understanding, the system to which this application applies will first be described. The vehicle air conditioning adjustment method provided in this application can be applied to, for example... Figure 1In the system architecture shown, vehicle 100 includes an in-vehicle terminal 110. The in-vehicle terminal 110 acquires environmental information inside the vehicle, a clothing index, and the body surface temperature of occupants in each seat. Based on the body surface temperature, it determines the temperature of a target area for any occupant in any seat. Based on the target area temperature, environmental information, and clothing index, it determines the human comfort index inside the vehicle. Based on the human comfort index, it adjusts the air conditioning's outlet temperature and / or airflow. The in-vehicle terminal 110 can be, but is not limited to, various personal computers or laptops connected to the vehicle.

[0049] Figure 2 This application provides a flowchart of a vehicle air conditioning adjustment method, which can be implemented by, for example... Figure 1 The vehicle-mounted terminal 110 in the system shown executes this. For example... Figure 2 As shown, the method may include the following steps:

[0050] S210 acquires environmental information inside the vehicle, clothing index, and body surface temperature of occupants in each seat.

[0051] The vehicle is equipped with a rear-view infrared camera, typically positioned near the center rearview mirror. This camera's beam can illuminate the front and rear seats, allowing the system to obtain the surface temperature of objects within the illuminated area. For example... Figure 3 As shown, the black dots represent the rear-view infrared camera. This camera is installed near the center rearview mirror and can collect the temperature of objects inside the vehicle with a wide scattering angle of α degrees, including the temperature of the human body surface in each seat, the temperature of the interior trim at different points inside the vehicle, and the overall interior temperature. The value of α ranges from (60° to 150°), and is typically set to 120°.

[0052] The environmental information may include the vehicle ambient temperature and the user-set temperature. The vehicle ambient temperature refers to the temperature conditions inside the vehicle, which is crucial for ensuring passenger comfort, vehicle performance, and safety. The user-set temperature is the air conditioning temperature entered by the user through the in-vehicle terminal's display screen, representing the needs of the passengers inside the vehicle.

[0053] The temperature values ​​of the human body surface can include the temperature values ​​of the head, chest and other body parts. Each seat includes the front seats and the rear seats. The front seats include the driver's seat and the front passenger seat.

[0054] The clothing index is used to characterize the thickness of clothing worn by a person; a higher clothing index indicates that the person is wearing thicker clothing. The vehicle occupant monitoring system uses algorithms to identify the thickness of clothing at the cuffs, collars, and other areas, and then calculates the clothing index based on this thickness. The clothing index is generated by the vehicle occupant monitoring system, and the vehicle's electronic control unit can receive this signal for calculation.

[0055] S220 determines the temperature value of a target part of a person in any seat in each seat based on the temperature value of the human body surface.

[0056] The target area is the head, chest, or other parts of the body. Generally, the head and chest are more sensitive to environmental comfort, so the head or chest is usually chosen as the target area.

[0057] The rear-view infrared camera creates a two-dimensional image of the object's surface within its scattering area, and can capture the temperature value of every point on this image. The number of temperature points captured in the two-dimensional image is related to the resolution of the rear-view infrared camera; for example, a resolution of 192*256 allows for the collection of 49,152 temperature values.

[0058] The system retrieves all temperature values ​​for the target area from the body surface temperature data, filters a preset number of temperature values ​​from these values, and calculates the average of these preset number of temperature values ​​as the target area temperature value. This target area temperature value can be from any seat in any row, thus taking into account the comfort of passengers in each direction.

[0059] S230 determines the human comfort index inside the vehicle based on the temperature value of the target area, environmental information, and clothing index.

[0060] First, the target comfort temperature value inside the vehicle is determined based on environmental information. Then, the temperature gap value for the target area is determined based on the target area temperature value and the target area comfort temperature value. Finally, the human comfort index is determined based on the target area temperature gap value and the clothing index. By comprehensively considering key indices such as the clothing index, vehicle ambient temperature, user-set temperature, and human body surface temperature, the determined human comfort index can better reflect the actual experience of passengers inside the vehicle.

[0061] S240 adjusts the vehicle's air conditioning outlet temperature and / or air volume according to the human comfort index.

[0062] Based on the human comfort index and preset comfort index thresholds, determine whether the vehicle's air conditioning needs adjustment. If adjustment is necessary, choose to adjust the air conditioning's outlet temperature or airflow. When the required outlet temperature exceeds the air conditioning's adjustment limit, and the outlet temperature cannot reach the target temperature, then adjust the airflow. This reduces the impact of airflow on passenger comfort and minimizes discomfort caused by excessive fan speed adjustments.

[0063] As can be seen, this embodiment of the application obtains environmental information inside the vehicle, clothing index, and the temperature values ​​of the human body surface of people in each seat. Based on the temperature values ​​of the human body surface, it determines the temperature value of a target part of a person in any seat. Based on the temperature value of the target part, environmental information, and clothing index, it determines the human comfort index inside the vehicle. Based on the human comfort index, it adjusts the air outlet temperature and / or air volume of the vehicle's air conditioning. This comprehensively considers key indices such as clothing index, vehicle environmental information, and human body surface temperature, making the determined human comfort index more closely match the actual feelings of passengers inside the vehicle and improving the user experience.

[0064] As one feasible method, the temperature value of a target body part of a person in any seat in each seat is determined based on the temperature value of the human body surface, including:

[0065] Obtain the temperature value of the target point corresponding to the target part from the temperature value of the human body surface;

[0066] Based on the temperature value of the target point corresponding to the target part, determine the temperature threshold point of the target part;

[0067] Centered on the temperature threshold point, select at least one preliminary temperature value point around it. The difference between the temperature value of the preliminary temperature value point and the temperature value of the temperature threshold point is less than the preset temperature difference.

[0068] Based on at least one pre-set temperature value point, determine the target body part temperature value for any person in any seat in each seat.

[0069] The target points are at least one pre-defined fixed point distributed across the target body part. These fixed points must have a very high probability of landing on the target body part regardless of its movement. The temperature values ​​of the target points corresponding to the target body part are obtained from the body surface temperature data. The number of target points can be set according to requirements.

[0070] Based on the temperature value of the target point corresponding to the target part, determine the temperature threshold point of the target part. Specifically, delete the maximum and minimum values ​​of the temperature value of the target point corresponding to the target part to obtain the remaining temperature value.

[0071] The target point whose temperature value differs the least from the average of the remaining temperature values ​​is determined as the temperature threshold point of the target location.

[0072] Taking a target point setting of 5 as an example, the number of temperature values ​​corresponding to the target points of the target area is 5, obtained from the temperature values ​​of the human body surface. The maximum and minimum values ​​of these 5 temperatures are then removed, leaving 3 remaining temperature values. The average of these remaining 3 temperature values ​​is then calculated. The target point whose temperature value differs the least from the average of the remaining temperature values—that is, the point corresponding to the remaining 3 temperature values ​​that is closest to the average—is selected as the temperature threshold point for the target area.

[0073] Using the temperature threshold point as the center, at least one preliminary temperature value point is selected in all four directions (up, down, left, and right) around it. If the temperature difference between the selected point and the temperature threshold point is greater than a preset temperature difference, the point is discarded. If the temperature difference is less than the preset temperature difference, the point is designated as a preliminary temperature value point. The preset temperature difference can be set according to the required precision of the data to be filtered, such as 1℃; this is not limited here.

[0074] Based on at least one pre-set temperature value point, determine the target body temperature value of any person in any seat in each seat. Specifically, take at least one pre-set temperature value point as the center and select pre-set temperature value points in all directions until the number of selected pre-set temperature value points reaches a preset number.

[0075] Based on the temperature values ​​of a preset number of pre-set temperature value points, determine the target body temperature value for any person in any seat within each seat.

[0076] Using the same method, starting from the initially selected preliminary temperature value points, continue to expand outwards in four directions (up, down, left, and right) to select more preliminary temperature value points until a preset number of points are selected. The preset number can be set according to the required precision of the data to be filtered, such as 20 points; there is no limit here.

[0077] The average temperature value of a preset number of pre-set temperature value points is used as the target body temperature value for any person in any seat.

[0078] As one feasible approach, the human comfort index inside a vehicle is determined based on the temperature value of the target area, environmental information, and clothing index, including:

[0079] Determine the target comfortable temperature value for the interior of the vehicle based on the vehicle's ambient temperature and the user's temperature setting.

[0080] Based on the target temperature value and the target comfort temperature value, determine the temperature gap value of the target part inside the vehicle;

[0081] The human comfort index inside the vehicle is determined based on the clothing index and the temperature gap value of the target area.

[0082] The environmental information includes the vehicle's ambient temperature and the user-set temperature. Through real-vehicle testing, users determine their own comfort temperature for the human body surface, resulting in a table comparing the vehicle's ambient temperature, the user-set temperature, and the target body part's comfort temperature values. For example,... Figure 4 As shown, when the ambient temperature of the vehicle is 20℃ and the user sets the temperature to 22℃, the comfort experience of multiple people has determined that the human head temperature is most comfortable at 26℃. Therefore, 26℃ is determined as the comfortable temperature value for the human head.

[0083] The temperature gap value M of the target area is obtained by calculating the difference between the target area temperature value and the target area comfort temperature value using the following formula:

[0084] M = Ta - Tc

[0085] Where Ta represents the target temperature value, Tc represents the target comfort temperature value, and the larger M is, the hotter it is, and the smaller M is, the colder it is.

[0086] Based on the clothing index and the temperature gap value M of the target area, a comparison table between the clothing index and the temperature gap value of the target area obtained from pre-testing and the human comfort index is used, as follows: Figure 5 As shown, when the clothing index is 1 and M is (-3,3), the human comfort index is 0.

[0087] As one feasible method, adjusting the air conditioning temperature or air volume of a vehicle based on the human comfort index includes:

[0088] Adjust the air temperature or air volume of the vehicle's air conditioner based on the human comfort index and preset comfort index thresholds.

[0089] According to the definition of the human comfort index, the human body is in the best state when the human comfort index is 1. Therefore, the maximum threshold of the preset comfort index threshold is defined as 1.2 and the minimum threshold is 0.8. When the human comfort index is in the range of (0.8, 1.2), the human body is in the best comfort state. At this time, there is no need to adjust the air outlet temperature and air outlet volume.

[0090] When the Human Comfort Index is greater than or equal to 1.2, the human body feels too hot. In this case, it is necessary to lower the outlet air temperature or reduce the air volume to adjust the temperature so that the Human Comfort Index reaches (0.8, 1.2). The amount by which the outlet air temperature or air volume needs to be reduced needs to be calibrated. The greater the difference between the Human Comfort Index and 1.2, the greater the reduction in outlet air temperature or air volume, and the longer the time required.

[0091] When the human comfort index is less than 0.8, the body feels cold. In this case, it is necessary to increase the outlet air temperature or increase the air volume to adjust the body comfort index to (0.8, 1.2). The amount of increase in outlet air temperature or air volume needs to be calibrated. The greater the difference between the human comfort index and 0.8, the greater the increase in outlet air temperature or air volume, and the longer the delay.

[0092] One feasible method is to adjust the air temperature and air volume of the vehicle's air conditioning system based on the human comfort index, including:

[0093] When the air outlet temperature of the vehicle's air conditioner is adjusted to be lower than the lower limit of the air outlet temperature based on the human comfort index and the preset comfort index threshold, the current air outlet volume, current air outlet temperature, and change value of the air outlet temperature are obtained.

[0094] Adjust the airflow of the vehicle's air conditioner based on the current airflow volume, current airflow temperature, and changes in airflow temperature.

[0095] When the required air outlet temperature exceeds the air conditioner's adjustment limit, the air outlet temperature cannot be lowered further. For example, if the current air outlet temperature is 8°C, calculations show that the air outlet temperature needs to be lowered by 5°C, meaning the target air outlet temperature is 3°C. However, the air conditioner's adjustment limit is only 6°C, so the target air outlet temperature cannot be reached. In this case, the air volume needs to be adjusted.

[0096] Obtain the current air volume M, current air temperature T, and air temperature change T1 of the air conditioner. Let the adjusted air volume be M1. According to the law of conservation of energy, M(T+T1)=M1T, so M1=M+MT1 / T.

[0097] If M1 has exceeded the upper limit of the adjustable air volume of the air conditioner, then adjust the air volume of the air conditioner to the upper limit of the air volume and the air temperature to the lower limit of the air temperature.

[0098] It should be understood that, although Figure 2 The steps in the flowchart are shown sequentially as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated in this application, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Furthermore, Figure 2 At least some of the steps in the process may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least some of the sub-steps or stages of other steps.

[0108] As one possible approach, the adjustment module 640 is specifically used to adjust the air outlet temperature or air volume of the vehicle's air conditioning system based on the human comfort index and a preset comfort index threshold.
