Description

The car's cabin has a strong heat exchange with the outside world. Under natural conditions, the cabin temperature is usually very high in summer, even reaching the level that can catch fire on flammable items, while the cabin temperature is very low in winter. Therefore, the car's air-conditioning system must be used to cool or heat the environment in the cabin, thereby adjusting the cabin temperature to a comfortable level for the human body and ensuring the car's driving safety and riding experience.

The current vehicle air conditioning system cools or heats the air in the cabin, thereby raising or lowering the temperature of the overall environment in the cabin. However, due to the different materials of different interior decorations in the cabin and the different contact conditions with human skin, different interior decorations produce different body temperatures for the driver and passengers. The current vehicle air conditioning system cools or heats the entire cabin, and its efficiency is low. Without turning on the cooling or heating in advance, it takes a long time for the entire cabin to reach the target temperature that makes the human body comfortable, and during this time, the driver and passengers in the car are in a state of low comfort; even if the cooling or heating method is turned on in advance, due to the low efficiency, it takes a long time to reach the temperature state that meets the human body's comfort needs, that is, it is necessary to start the car components in advance for a long time, resulting in high energy consumption. In addition, if the vehicle air conditioning is turned on too early to cool or heat the cabin environment, the air outlet will always blow towards the central control armrest or door trim armrest that is in contact with human skin, and it is easy to have the problem of the interior temperature being too low or too high, and people feel uncomfortable when touching it.

DETAILED DESCRIPTION

In this embodiment, the vehicle air conditioning control method for adjusting the temperature of the vehicle interior can be applied to the vehicle system shown in FIG. 1 .

1 , a vehicle system to which a vehicle air conditioner control method for adjusting the temperature of a vehicle interior can be applied includes an interior, a control module, an image sensor, a temperature sensor, and a vehicle air conditioner.

Among them, the interior is a component arranged in the cockpit of the car, such as a center console, a steering wheel, an instrument panel, a shift lever, a seat, a headrest, an armrest box, a door handle, a seat belt, an ambient light, etc., and FIG1 is provided with n interiors, such as interior 1, interior 2... interior n; the control module is a component with functions such as data acquisition, data processing, data output and control, and can specifically be an electronic control unit (ECU); the image sensor can shoot the space in the cockpit by means of visible light or infrared rays, and the field of view of the image sensor is large enough to include a large number of interiors in the cockpit, for example, the n interiors in FIG1 are all within the field of view of the image sensor; the temperature sensor has a temperature detection function, and referring to FIG1, a total of n temperature sensors, such as temperature sensor 1, temperature sensor 2... temperature sensor n, are provided, wherein temperature sensor 1 is installed on interior 1 to detect the temperature of interior 1, temperature sensor 2 is installed on interior 2 to detect the temperature of interior 2... temperature sensor n is installed on interior n to detect the temperature of interior n.

In this embodiment, the image sensor and the temperature sensor may be provided selectively, that is, only the image sensor may be provided without the temperature sensor, or only the temperature sensor may be provided without the image sensor.

In this embodiment, the vehicle air conditioner can have both cooling and heating functions, or only has cooling function. Since the cooling function is a typical function of the vehicle air conditioner, in this embodiment, cooling is taken as an example to illustrate the vehicle air conditioner control method for automobile interior temperature adjustment. In the absence of special instructions, when the vehicle air conditioner is controlled to work, the vehicle air conditioner is controlled to cool by default. The process of controlling the vehicle air conditioner to heat, etc. can be obtained by controlling part of the control logic according to the opposite logic on the basis of the process of controlling the vehicle air conditioner to cool, which is within the scope that can be understood by those skilled in the art.

In this embodiment, referring to FIG1 , the vehicle air conditioner is provided with an air outlet, and the air outlet can adjust the airflow direction of the cold air or hot air blown by the fan of the vehicle air conditioner, so that the cold air or hot air is blown directly to the target position. The target position directly blown by the cold air or hot air will be cooled or heated quickly, so that the target temperature can be reached in a short time (for example, 5 seconds). Compared with when it is not directly blown, the temperature change rate is greatly improved. In the case of not being directly blown, the target position may take a long time (for example, 5 minutes) to reach the target temperature.

In this embodiment, by increasing the air flow rate of the air outlet and the swing range of the fan blades, the air supply range of the air outlet can be made large enough and adjustable, so that the air outlet can change the air supply direction within a large enough range, for example, any one or more of the large number of interior decorations on the car can be selected as the air supply target, and air can be supplied to the air supply target specifically. The air outlet structure can be improved to improve the concentration of air supply, for example, the air outlet is made to supply air specifically to interior decoration 1, and at this time, interior decoration 2, interior decoration 3... interior decoration n and other interior decorations will not be directly blown by the air blown out of the air outlet, or the air volume directly blown is so small that it can be ignored.

In this embodiment, referring to FIG. 2 , a vehicle air conditioning control method for adjusting the temperature of a vehicle interior comprises the following steps:

S1. Obtaining actual temperature distribution information;

S2. Obtain target temperature distribution information;

S3. Determine the air conditioning control information according to the actual temperature distribution information and the target temperature distribution information;

S4. Control the operation of the vehicle air conditioner according to the air conditioner control information.

In this embodiment, each step in the vehicle air conditioning control method for adjusting the temperature of the automobile interior can be executed by the control module. When the control module needs to obtain some data, the control module can call other components to read it; when the control module needs to execute steps that require physical components to execute, the control module can send control instructions to other components, thereby calling other components to execute.

In this embodiment, the principles of steps S1-S4 are shown in FIG3 .

In step S1, the actual temperature distribution information acquired by the control module represents the spatial distribution of the actual temperature of at least one vehicle interior in the cabin. For example, a format and content of the actual temperature distribution information are shown in Table 1.

Table 1

Interior Actual temperature Space Coordinates Interior 1 T ₁ (x ₁ ,y ₁ ,z ₁ ) Interior 2 T ₂ (x ₂ ,y ₂ ,z ₂ ) Interior 3 T ₃ (x ₃ ,y ₃ ,z ₃ ) … … … Interior T _n (x _n ,y _n ,z _n )

According to Table 1, the spatial coordinates of the interior trim 1 in the cabin are (x ₁ , y ₁ , z ₁ ), and the actual temperature of the interior trim 1 is detected to be T ₁ . The actual temperature of each interior trim can be found from Table 1.

In step S2, the target temperature distribution information obtained by the control module indicates the spatial distribution of the target temperature that at least one vehicle interior in the cabin needs to reach. For example, a format and content of the target temperature distribution information are shown in Table 2.

Table 2

According to Table 2, the spatial coordinates of interior 1 in the cabin are (x ₁ , y ₁ , z ₁ ), and the target temperature of interior 1 is detected to be T' ₁ , that is, it is hoped that after turning on the vehicle air conditioner for cooling, the temperature of interior 1 will be reduced to T' ₁ . The target temperature of each interior can be found in Table 2.

The target temperature distribution information in step S2 can be set by the driver and passenger according to their own physical preferences. For example, the driver can set specific values of _T'1 , _T'2 ... _T'n , etc. one by one according to their own comfort range. It is also possible to calibrate the target temperature that can make the human body comfortable in different regions, seasons, day and night conditions in an environment such as a laboratory, and store it in the storage space of the control module. The control module can call the positioning module and the timing module to detect the region, season, day and night information of the car, and read the corresponding specific values of _T'1 , _T'2 ... _T'n , etc. from the storage space, so as to set the target temperature distribution information in batches.

In step S3, the control module determines the air conditioning control information according to the actual temperature distribution information obtained in step S1 and the target temperature distribution information obtained in step S2. Specifically, the air conditioning control information includes information such as the target air supply volume and the position of the air supply target. When the control module executes step S4 and controls the operation of the vehicle air conditioner according to the air conditioning control information, the air conditioning control information is sent to the vehicle air conditioner, so that the vehicle air conditioner supplies air to the air supply target according to the target air supply volume and the position of the air supply target.

In this embodiment, the principle of executing steps S1-S4 is that: since the actual temperature distribution information and the target temperature distribution information include the spatial distribution of the actual temperature and the spatial distribution of the target temperature respectively, the generated air-conditioning control information can include the spatial distribution of a specific temperature, so that when the vehicle air-conditioning is controlled to work according to the air-conditioning control information, the air supply outlet of the vehicle air-conditioning can be controlled to supply air to a specific spatial position, for example, to supply air to one or more specific interiors, so that the specific interiors can reach the target temperature faster; it can be achieved that specific interiors that have a greater impact on the body temperature of the driver and passengers (such as seats, headrests and steering wheels that are in contact with the skin of the driver and passengers over a large area) are selected for priority air supply, so that these specific interiors can reach the target temperature faster, thereby achieving the effect of improving the body temperature of the driver and passengers in the cabin in a shorter time; since there is no need to wait for all interiors to reach the target temperature, the uncomfortable time of the driver and passengers can be reduced and the driving comfort can be improved when the vehicle air-conditioning is not started in advance, and the required advance start time can be reduced when the vehicle air-conditioning is started in advance, thereby achieving the effects of rapid response and reduced energy consumption.

In this embodiment, when executing step S1, that is, the step of obtaining actual temperature distribution information, the following steps may be specifically performed:

S101A. Call at least one interior temperature sensor;

S102A. Obtaining location information of each interior temperature sensor;

S103A. Detecting temperature information through each interior temperature sensor;

S104A. Mark the temperature information detected by the interior temperature sensor according to the position information of the interior temperature sensor to obtain actual temperature distribution information.

Steps S101A-S104A are the first execution mode of step S1.

In step S101A, referring to FIG1 , an interior temperature sensor may be installed for each interior decoration (e.g., seats, steering wheels, armrest boxes, and other interior decorations that are large in size and in close contact with the driver and passengers), and the position information of each interior temperature sensor may be determined by calibration. The interior decoration temperature sensor may be a temperature sensor that measures based on the principle of resistance temperature effect, etc. Each interior decoration temperature sensor is installed together with the corresponding interior decoration, that is, the position information of each interior decoration temperature sensor may be the same as the position of the interior decoration where it is installed. For example, referring to FIG1 , temperature sensor 1 is installed together with interior decoration 1, and referring to Table 1, the spatial coordinates of interior decoration 1 are determined to be (x ₁ ,y ₁ ,z ₁ ) by calibration, etc., then the position information of temperature sensor 1 in step S102A may be the same as the spatial coordinates of interior decoration 1, that is, (x ₁ ,y ₁ ,z ₁ ).

In step S103A, referring to FIG. 1 , the control module calls temperature sensor 1, temperature sensor 2, ... temperature sensor n, etc., to respectively detect and obtain temperature information T ₁ of interior 1, temperature information T ₂ of interior 2, ... temperature information T _n of interior n. In step S104A, position information such as (x ₁ , y ₁ , z ₁ ), (x ₂ , y ₂ , z ₂ ) ... (x _n , _yn , z _n ) are used for marking, so as to obtain actual temperature distribution information shown in Table 1.

In this embodiment, by executing steps S101A-S104A and using the interior temperature sensor to detect and obtain the actual temperature distribution information, the characteristics of the interior temperature sensor can be used to improve the accuracy and real-time performance of the actual temperature distribution information. In addition, generally, one temperature sensor is installed for one interior. Therefore, in the actual temperature distribution information shown in Table 1, each actual temperature can correspond to a specific interior (for example, interior 1 is a steering wheel. According to Table 1, it can be known that the actual temperature of interior 1, i.e., the steering wheel, is _T1 ), thereby improving the comprehensibility of the data and making the granularity of the actual temperature distribution information shown in Table 1 large, which is conducive to reducing the required data processing amount.

In this embodiment, when executing step S1, that is, the step of obtaining actual temperature distribution information, the following steps may be specifically performed:

S101B calls the image sensor to capture the space inside the car cabin to obtain an image inside the cabin;

S102B. Identify objects in the cabin image and determine at least one vehicle interior and corresponding location information;

S103B performs temperature recognition on the image in the cabin to determine the temperature information of each position in the image in the cabin;

S104B. Mark the temperature information of the corresponding position in the image inside the cabin according to the position information of the car interior, and obtain the actual temperature distribution information.

Steps S101B-S104B are a second execution mode of step S1.

In step S101B, the control module can call the image sensor to capture the space inside the car cabin by infrared imaging to obtain the cabin image. The cabin image includes pixel values corresponding to various positions in the cabin (both positions on the interior and positions not belonging to the interior).

In step S102B, the control module may run the trained artificial intelligence model to perform object recognition on the cabin image, and determine at least one car interior and corresponding position information. For example, the artificial intelligence model recognizes an area with a steering wheel contour feature from the cabin image, thereby determining it as interior 1, i.e., the steering wheel, and obtains the relative position of this area in the cabin image, and determines the position information of interior 1 by establishing a conversion between the coordinate system in the cabin image and the cabin space coordinate system. The position information of the interior can be expressed in the form of spatial coordinates (x ₁ , y ₁ , z ₁ ) in Table 1 or Table 2.

In step S103B, when the cabin image is obtained by infrared imaging, the control module can determine the temperature corresponding to each pixel in the cabin image by querying the correspondence between pixel value and temperature, thereby determining the temperature of each area in the cabin image.

In step S104B, taking interior 1 as an example, the control module can obtain the temperature of all pixels in the area corresponding to interior 1 in the cabin image, calculate the average value as the actual temperature T ₁ of interior 1, and mark it with the spatial coordinates (x ₁ , y ₁ , z ₁ ) of interior 1. Similar operations are performed on all interiors to obtain the actual temperature distribution information shown in Table 1.

In this embodiment, the actual temperature distribution information is obtained by performing steps S101B-S104B through image capture and recognition, which can utilize the fast characteristics of the image capture and recognition process, and the number of pixels in the image in the cabin is large, generally much more than the number of interior temperature sensors, so the actual temperature distribution information of each position in the cabin tends to be continuously distributed can be obtained. In the actual temperature distribution information obtained in Table 1, interior 1, interior 2, etc. may not strictly correspond to a specific interior, but correspond to a certain area space in the cabin (for example, interior 1 in Table 1 may not correspond to the entire steering wheel, but to the upper half of the steering wheel, and interior 2 corresponds to the lower half of the steering wheel, and interior 1 and interior 2 together correspond to a complete interior, i.e., the steering wheel). At this time, the number n in Table 1 can be very large (for example, up to 10 ⁶ ), so that the actual temperature distribution information obtained in Table 1 tends to be continuously distributed.

In this embodiment, when executing step S3, that is, determining the air conditioning control information according to the actual temperature distribution information and the target temperature distribution information, the following steps may be specifically performed:

S301. Determine the temperature difference distribution information according to the actual temperature distribution information and the target temperature distribution information;

S302. Determine air conditioning control information according to the temperature difference distribution information.

In step S301, for each interior, a corresponding temperature difference of the interior is determined according to the actual temperature of the interior and the target temperature.

For example, according to Table 1, the actual temperature of interior 1 is T ₁ , and according to Table 2, the target temperature of interior 1 is T' ₁ . Because the actual temperature T ₁ is generally higher than the target temperature T' ₁ under cooling demand, the difference ΔT ₁ between the actual temperature T ₁ and the target temperature T' ₁ can be calculated, i.e., ΔT ₁ =T ₁ -T' ₁ , as the temperature difference ΔT ₁ corresponding to interior 1 , and the position information corresponding to the temperature difference ΔT ₁ is still the spatial coordinates corresponding to interior 1 , i.e., (x ₁ , y ₁ , z ₁ ).

By performing similar operations on all interiors, the temperature difference distribution information shown in Table 3 can be obtained.

Table 3

Interior Temperature difference (absolute value) Space Coordinates Interior 1 |ΔT ₁ | (x ₁ ,y ₁ ,z ₁ ) Interior 2 |ΔT ₂ | (x ₂ ,y ₂ ,z ₂ ) Interior 3 |ΔT ₃ | (x ₃ ,y ₃ ,z ₃ ) … … … Interior |ΔT _n | (x _n ,y _n ,z _n )

In step S302, the control module may generate air conditioning control information according to the temperature difference distribution information shown in Table 3.

In this embodiment, when executing step S302, that is, determining the air conditioning control information according to the temperature difference distribution information, the following steps may be specifically performed:

S30201. Set the temperature difference threshold;

S30202. According to the temperature difference threshold, the temperature difference information at each position in the temperature difference distribution information is screened to determine at least one temperature difference maximum value information;

S30203. Perform path planning based on the position information corresponding to each temperature difference maximum value information to obtain air supply path information;

S30204. Set the target air supply volume;

S30205. Generate air conditioning control information based on the air supply path information and the target air supply volume.

In step S30201, the control module may set a temperature difference threshold Threshold _T , _which may be a fixed value used to determine the size of a temperature difference information. For example, if a temperature difference information obtained in step S301 is greater than or equal to the temperature difference threshold Threshold _T , it may be determined that the temperature difference information is relatively large, and conversely, if the temperature difference information is less than the temperature difference threshold Threshold _T , it may be determined that the temperature difference information is relatively small.

In step S30202, the control module compares each temperature difference information |ΔT ₁ |, |ΔT ₂ |, ..., |ΔT _n | in Table 3 with the temperature difference threshold Threshold _T one by one, and selects the temperature difference information that is greater than or equal to the temperature difference threshold Threshold _T , that is, relatively large, and marks it as the maximum temperature difference information.

For example, assuming that when executing step S30202, it is detected that the temperature difference information |ΔT ₁ |, |ΔT ₃ |, |ΔT ₁₀₂ | are all greater than or equal to the temperature difference threshold Threshold _T , then the temperature difference information |ΔT ₁ |, |ΔT ₃ |, |ΔT ₁₀₂ | may be marked as temperature difference maximum value information.

In step S30203, the control module performs path planning according to the temperature difference maximum value information |ΔT ₁ |, |ΔT ₃ |, and |ΔT ₁₀₂ |, etc., to obtain air supply path information.

Specifically, referring to Table 1, Table 2 or Table 3, the temperature difference maximum value information |ΔT ₁ |, |ΔT ₃ | and |ΔT ₁₀₂ | correspond to interior 1, interior 3 and interior 102, respectively, and correspond to the spatial coordinates (x ₁ , y ₁ , z ₁ ), (x ₃ , y ₃ , z ₃ ) and (x ₁₀₂ , y ₁₀₂ , z ₁₀₂ ), respectively. The control module can perform path planning according to the spatial coordinates (x ₁ , y ₁ , z ₁ ), (x ₃ , y ₃ , z ₃ ) and (x ₁₀₂ , y ₁₀₂ , z ₁₀₂ ).

For example, the goal of path planning can be set to generate a closed path that passes through the location information corresponding to all temperature difference maximum value information [such as spatial coordinates (x ₁ , y ₁ , z ₁ ), (x ₃ , y ₃ , z ₃ ) and (x ₁₀₂ , y ₁₀₂ , z ₁₀₂ )], and the length of this path is the shortest. Corresponding weights may also be set for the position information corresponding to each maximum temperature difference information. For example, the position information corresponding to all maximum temperature difference information may be set to the same weight (for example, all are 1). Weights may also be set for the corresponding position information according to the size of the maximum temperature difference information itself [for example, the spatial coordinate (x ₁ , y ₁ , z ₁ ) is assigned a weight of |ΔT ₁ |, the spatial coordinate (x ₃ , y ₃ , z ₃ ) is assigned a weight of |ΔT ₃ |, and the spatial coordinate (x ₁₀₂ , y ₁₀₂ , z ₁₀₂ ) is assigned a weight of |ΔT ₁₀₂ |]. A path planning algorithm may be run on the position information corresponding to each weighted maximum temperature difference information, and constraints may be set according to the above path planning objectives to generate a corresponding closed path as the air supply path information.

In this embodiment, it is assumed that the generated closed path path, that is, the air supply path information path, is ( _x1 , _y1 , _z1 )→( _x102 , _y102 , _z102 )→( _x3 , _y3 , _z3 ), that is, when moving according to the air supply path information path, it can start from the spatial coordinate ( _x1 , _y1 , _z1 ), first jump to the spatial coordinate ( _x102 , _y102 , _z102 ), then jump to the spatial coordinate ( _x3 , _y3 , _z3 ), and then return to the spatial coordinate ( _x1 , _y1 , _z1 ), and so on.

In step S30204, the control module can set the target air supply volume according to parameters such as the performance of the vehicle air conditioner.

In step S30205, the control module packages the air supply path information path and the target air supply volume to generate air conditioning control information.

In this embodiment, the principle of executing steps S30201-S30205 is: by using the temperature difference threshold to filter out the temperature difference maximum value information, it is possible to find the position information where the actual temperature is farthest from the target temperature, that is, the position information corresponding to each of the temperature difference maximum value information, and perform path planning on these position information to obtain the air supply path information, which represents a path that meets the conditions (for example, passes through all the position information with the largest temperature difference and has the shortest total path length). Such air supply path information is packaged to generate air conditioning control information, so that when the control module executes step S4 and uses the air conditioning control information to control the vehicle air conditioner, the vehicle air conditioner controls its air outlet, and according to the air supply target and sequence determined by the air supply path information [for example, (x ₁ , y ₁ , z ₁ )→(x ₁₀₂ ,y ₁₀₂ ,z ₁₀₂ )→(x ₃ ,y 3 ,z ₃ )], cyclically performs the air supply target [for example, the interior decoration 1 corresponding to the spatial coordinate (x ₁ ,y ₁ ,z 1 ) and the spatial coordinate (x 3 ,y ₃ ,z 3 ) corresponding to the spatial coordinate (x 1 ,y 1 ,z ₁ )] The interior decoration 102 corresponding to the spatial coordinates (x ₁₀₂ ,y ₁₀₂ ,z ₁₀₂ ) and the interior decoration 3 corresponding to the spatial coordinates (x ₃ ,y ₃ ,z ₃ ) are supplied with air according to the target air supply volume; since each air supply target determined by the air supply path information corresponds to the temperature difference maximum value information, that is, they are all air supply targets with the most urgent air supply demand, executing steps S30201-S30205 can control the vehicle air conditioner to give priority to the air supply targets with the most urgent air supply demand, so that these interior decorations can reach the target temperature faster and speed up the improvement of the driver and passenger's body temperature; and since the air supply path information meets certain conditions (for example, the shortest total length), the air supply range of the air outlet of the vehicle air conditioner can be limited to a smaller range. Specifically, the swing range of the fan blades in the air outlet of the vehicle air conditioner can be reduced, thereby reducing the working loss of the vehicle air conditioner and reducing maintenance costs.

In this embodiment, when executing step S301, that is, determining the temperature difference distribution information according to the actual temperature distribution information and the target temperature distribution information, the following steps may be specifically performed:

S30101. Subtract the temperature information corresponding to the same position in the actual temperature distribution information and the target temperature distribution information to obtain the temperature difference information of each position;

S30102. Determine the temperature difference field according to the temperature difference information at each location;

S30103. Obtain the gradient size of each position of the temperature difference field;

S30104. When the magnitudes of all gradients are less than the gradient threshold, the temperature difference field itself is used as the temperature difference distribution information;

S30105. When any gradient is greater than or equal to the gradient threshold, the temperature difference field is fuzzy;

S30106. Use the fuzzy temperature difference field as the temperature difference distribution information.

In step S30101, the temperature difference information obtained is |ΔT ₁ |, |ΔT ₂ |, ..., |ΔT _n |, etc. in Table 3.

In step S30102, referring to Table 3, each piece of temperature difference information corresponds to a corresponding spatial coordinate, so the data shown in Table 3 can be regarded as a temperature difference field.

In step S30103, the temperature difference field shown in Table 3 may be interpolated to make it a continuous field and then the gradient magnitude at each position may be calculated. Alternatively, a discrete gradient algorithm may be used to calculate the gradient magnitude at each position.

In steps S30104 and S30105, a gradient threshold Threshold _Gradient may be set, and the gradient threshold Threshold _Gradient may be a fixed value used to determine whether a gradient size is relatively large or relatively small. For example, if a gradient size obtained in step S30103 is greater than or equal to the gradient threshold Threshold _Gradient , it can be determined that the gradient size is relatively large. Conversely, if the gradient size is less than the gradient threshold Threshold _Gradient , it can be determined that the gradient size is relatively small.

If all the gradient sizes obtained in step S30103 are less than the gradient threshold Threshold _Gradient , that is, it is determined that all the gradient sizes of the temperature difference field shown in Table 3 are relatively small, then step S30104 is executed, and the temperature difference field itself shown in Table 3 is directly used as the temperature difference distribution information used when executing step S302 to generate air conditioning control information.

If any gradient size obtained in step S30104 is greater than or equal to the gradient threshold Threshold _Gradient , that is, it is determined that there are some locations in the temperature difference field shown in Table 3 where the gradient size is relatively large, then step S30105 is executed to fuzzify the temperature difference field shown in Table 3, and the fuzzified temperature difference field is used as the temperature difference distribution information used when executing step S302 to generate air conditioning control information.

When executing step S30105, Table 3 can be regarded as an image (similarly, the data in Table 1 and Table 2 can also be stored and processed in the form of images). Specifically, the spatial coordinates in Table 3 represent the pixel coordinates of the image, and the temperature difference in Table 3 represents the pixel value of the pixel. Therefore, the image can be blurred using algorithms such as Gaussian blur to obtain the blurred temperature difference field as temperature difference distribution information.

In this embodiment, the principle of executing steps S30101-S30105 is that the gradient size at each position of the temperature difference field indicates the smoothness of the distribution of the temperature difference field. When the gradient sizes are all less than the gradient threshold, it means that the temperature difference field is smooth enough, and the temperature difference field itself can be used as the temperature difference distribution information; when any gradient size is greater than or equal to the gradient threshold, it means that the temperature difference field is not smooth enough, and blurring the temperature difference field can make the temperature difference field smoother, and the blurred temperature difference field can be used as the temperature difference distribution information; that is, executing steps S30101-S30105, the obtained temperature difference distribution information is obtained based on the temperature field, and the distribution of the temperature difference is smooth enough, which is conducive to determining the temperature difference maximum value information and planning the air supply path information with finer force when executing step S302 later, which is conducive to the control module controlling the vehicle air conditioner to perform more detailed air supply control on the space in the cabin, further improving the temperature distribution of the cabin, and meeting more delicate personalized needs.

In addition, when executing steps S101A-S104A and using the interior temperature sensor to detect and obtain actual temperature distribution information, since the temperature sensor is arranged on the interior component, it can be monitored that when the interior temperature reaches the specified temperature, the direction and air volume of the vehicle air-conditioning outlet can be intelligently adjusted to keep the surface temperature of the interior component at a comfortable temperature.

In this embodiment, when executing step S4, that is, the step of controlling the operation of the vehicle air conditioner according to the air conditioner control information, the following steps may be specifically performed:

S401. Get the air conditioning reservation start control instruction;

S402. According to the air conditioning reservation start control instruction, determine the air conditioning use time;

S403. Determine the advance opening time according to the air supply path information;

S404. Determine the air conditioning start time according to the air conditioning use time and advance start time;

S405. When the air conditioner is started, the vehicle air conditioner is controlled to cool or heat according to the target air supply volume, and to supply air according to the air supply path information.

In step S401, the driver and passenger can set the air conditioning scheduled start control instruction through the human-computer interaction module. The air conditioning scheduled start control instruction indicates that the driver and passenger want to start the vehicle air conditioning in advance. The air conditioning scheduled start control instruction includes the air conditioning use time _t2 , _which indicates the time when the driver and passenger are expected to enter the cabin of the car.

In step S402, the control module extracts the air conditioner use time _t2 from the air conditioner scheduled start control instruction.

In step S403, the control module can determine the advance opening time length Δt according to the length of the air supply path information path. Specifically, generally speaking, the swing speed of the fan blades of the air outlet is fixed, so the advance opening time length Δt can be set as a proportional function of the length of the air supply path information path. For example, the time required for the air outlet to complete a cycle of the air supply path information path can be determined based on the length of the air supply path information path and the swing speed of the fan blades, and then multiplied by the set number of required cycles to obtain the advance opening time length Δt.

In step S404, the air conditioner start time _t1 is determined according to the air conditioner use time _t2 and the advance start time Δt. Specifically, the air conditioner start time _t1 can be calculated according to the formula _t1 = _t2 - Δt.

In step S405, the control module controls the vehicle air conditioner at the air conditioner start-up time _t1 to perform cooling or heating according to the target air supply volume, and to supply air according to the order of each air supply target determined in the air supply path information path.

In this embodiment, the principle of executing steps S401-S405 is that: the air conditioner can be started in advance to cool or heat the cabin space, so that at the air conditioner use time t2 _, that is, when the driver and passengers enter the cabin, the temperature of the interior of the cabin has reached the appropriate target temperature distribution, thereby improving the driving experience; and the time for starting the air conditioner in advance, that is, the advance start time Δt, just enables the vehicle air conditioner to give priority to supplying air to the key interior to meet the number of times required, thereby reducing unnecessary advance start time of the vehicle air conditioner, reducing unnecessary work of the vehicle air conditioner, and helping to reduce energy consumption.
