[0002] As an important device for improving the comfort of car riding, the vehicle air conditioner is an indispensable part in the car. When the temperature inside and outside the car is high, the pores of the human body will spread sweat, which will wet the clothes. If the vehicle air conditioner is used to blow cold air directly to the human body when the sweat has not stopped or the clothes have not dried, it will easily cause wind-chill if the time is too long. At the same time, because the cold air is not easy to dry the clothes, the clothes will still be wet after the human body adapts to the environment temperature, which will cause discomfort. Therefore, it is necessary to create a suitable environment in the car to ensure the normal driving or riding feeling of the people in the car and avoid the influence of high temperature in the car on the fatigue, comfort and driving efficiency of the people in the car.

[0064] To make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings.

[0065] As Figure 1 shown, a main flow diagram of an embodiment of a vehicle air conditioning air supply control method provided by the present application is shown. In combination with Figure 2 shown, the method at least includes the following steps:

[0066] Step S10, obtaining image information of each seat in the vehicle, body surface temperature information of the person in the seat, and vehicle humidity information;

[0067] Step S11, inputting the obtained information into a pre-trained neural network to obtain the dry and wet degree attribute on the body of each person in the seat;

[0068] Step S12, obtaining the corresponding air supply temperature according to the dry and wet degree attribute on the body of each person, and controlling the vehicle air conditioner to perform air supply processing on the corresponding person in the seat at the air supply temperature.

[0069] The steps of the method of the embodiment of the present application will be described in detail below.

[0070] Specifically, in the embodiment of the present application, a coordinate system needs to be established for each seat in advance, and each seat area is divided into a plurality of predetermined size area blocks arranged horizontally and vertically in the coordinate system, and the coordinate information of each area block is determined according to the center of each area block. In a specific example, each seat area can be divided into a nine-square grid form.

[0071] In an example, the step S10 of obtaining the image information of each seat in the vehicle, the body surface temperature information of the person in the seat, and the vehicle humidity information is specifically:

[0072] The image information P of each seat is obtained by a plurality of cameras arranged in the vehicle; 图 The body surface temperature value T of the person in the seat is obtained by an infrared sensor arranged in the vehicle; 体 The vehicle humidity value H is obtained by a humidity sensor arranged in the vehicle; 湿 It can be understood that the humidity sensor can be multiple, for example, a humidity sensor can be arranged near each seat to detect the humidity of the clothes of the person in the vehicle;

[0073] It can be understood that in specific examples, by installing multiple cameras in the vehicle, for example, the cameras can be installed on the rearview mirror, steering wheel, A-pillar and B-pillar to capture images of the seats and the people in the seats. Each seat in the vehicle corresponds to a set of monitoring equipment, and each seat can correspond to at least one camera, an infrared sensor, at least one humidity sensor and a temperature sensor installed in the vehicle. In some examples, a humidity sensor can be additionally installed on the side of the seat to further obtain the clothing humidity information of the back of the person.

[0074] In some examples, once it is detected that a user has sat in the vehicle, the temperature in the vehicle is obtained by the temperature sensor in the vehicle, and it is determined whether the temperature in the vehicle is greater than or equal to a first temperature threshold (such as 27°C). If the temperature in the vehicle is >= the first temperature threshold (such as 27°C), the vehicle-mounted air conditioner is started to automatically cool. At the same time, the body surface temperature of the user is obtained by the infrared sensor installed near each seat, the image of the seat area where the user sits (i.e., the image of the area near the person and the seat) is obtained by the camera in the vehicle, and the humidity information in the vehicle is obtained by the humidity sensor.

[0075] In an embodiment of the present application, the step S11 of inputting the obtained information into a pre-trained neural network to obtain the dryness and wetness degree attributes of the people on each seat comprises:

[0076] The obtained image information, humidity value, and humidity value are input into a pre-set and trained neural network;

[0077] According to the plurality of region block information pre-divided for each seat in the vehicle, the dryness and wetness degree attributes of each region block in each seat are obtained by the neural network analysis;

[0078] The dryness and wetness degree attribute of the region block whose body area ratio is greater than a preset threshold in the recognition result is determined as the person attribute; the dryness and wetness degree attribute of the region block whose wet clothes area ratio is greater than a preset threshold in the recognition result is determined as the wet clothes attribute; the dryness and wetness degree attribute of the region block whose dry clothes area ratio is greater than a preset threshold in the recognition result is determined as the dry clothes attribute; and the dryness and wetness degree attribute of the region block with other recognition results is determined as the no person attribute.

[0079] In an embodiment of the present application, the neural network is pre-trained and can include the following structure:

[0080] The input layer is used to receive image information, temperature value and humidity value; specifically, P 图 After preprocessing (such as scaling to uniform size), the image information is sent to the subsequent CNN to extract features; T 体 Directly as an input node; H 湿 Directly as an input node;

[0081] The feature extraction layer uses a VGG16 or ResNet pre-trained CNN model as the basis to extract the clothing and dry-wet features in the image; the temperature and humidity features are input into the fully connected layer for linear transformation and non-linear planning to extract features related to clothing dry-wet;

[0082] The feature fusion layer is used to fuse the image features and temperature and humidity features through splicing, combine features from different sources, and form a fused feature vector from the combined features from different sources;

[0083] The hidden layer has a non-linear activation function to increase the non-linear expression capability of the model;

[0084] The output layer uses a Sigmoid activation function to map the output value to between 0 and 1, which is used to represent the area portion of the wet clothing.

[0085] At this time, the training method is supervised learning. By using a labeled data set for training, by comparing the difference between the calculated result and the actual result, and by updating the model parameters through the optimizer.

[0086] In a specific example, when the image recognized by the neural network shows that the area of the human body in a region block is greater than a preset first percentage (such as 90%) in the current region block, the dry-wet degree attribute of the region block is determined as the person attribute I 人 ;

[0087] When the image recognized by the neural network shows that the area of the wet clothing in a region block is greater than a preset second percentage (such as 90%) in the current region block, the dry-wet degree attribute of the region block is determined as the wet clothing attribute I 湿 ;

[0088] When the image recognized by the neural network shows that the area of the dry clothing in a region block is greater than a preset third percentage (such as 90%) in the current region block, the dry-wet degree attribute of the region block is determined as the dry clothing attribute I 干 ;

[0089] When the image recognized by the neural network shows that the region block does not meet the above three situations, the dry-wet degree attribute of the region block is determined as the no person attribute I 无 .

[0090] In a specific example, the step S12 obtains the corresponding supply air temperature according to the dry-wet degree attribute of each person, and controls the vehicle-mounted air conditioner to supply air to the corresponding person in the seat at the supply air temperature, further comprising:

[0091] Step S120, obtaining the air supply sequence of each air supply port to the blocks of each seat area, and determining the air supply area block of each air supply port of the vehicle air conditioner corresponding to the personnel;

[0092] For example, in one example, the air supply sequence can be in the order of the size of the coordinates of each block of each seat area, such as in the order of small to large, and the air supply can be performed in sequence; it can be understood that other air supply sequences can also be used in other examples, such as a wet clothing attribute priority air supply sequence.

[0093] Step S121, calculating the corresponding air supply temperature according to the dry and wet degree attribute of the air supply area block corresponding to each personnel;

[0094] In this step, the number of blocks with people, the number of blocks with dry clothes, the number of blocks with wet clothes, and the number of blocks without people are obtained, and the air supply temperature corresponding to each type of block is calculated in combination with the body surface temperature of the user.

[0095] Specifically, in one example, the step S121 further comprises:

[0096] For the blocks with the dry and wet degree attribute of people, the corresponding air supply temperature T is calculated by the following formula 人 :

[0097] T 人 =T 体 -(a1*N 无 +a2*N 干 +a3*N 人 +a4*N 湿 ) / M;

[0098] For the blocks with the dry and wet degree attribute of dry clothes, the corresponding air supply temperature T is calculated by the following formula 干 :

[0099] T 干 =T 体 -(b1*N 无 +b2*N 干 +b3*N 人 +b4*N 湿 ) / M;

[0100] For the blocks with the dry and wet degree attribute of wet clothes, the corresponding air supply temperature T is calculated by the following formula 湿 :

[0101] T 湿 =T 体 -(c1*N 无 +c2*N 干+c3*N 人 +c4*N 湿 ) / M;

[0102] For an area block with a humidity level attribute of "unoccupied", the corresponding supply air temperature T is calculated using the following formula. 无 :

[0103] T 无 =T 体 -d;

[0104] Among them, T 体 This corresponds to the body surface temperature of the person in the seat;

[0105] N 无 The dryness / wetness attribute is unmanned attribute I. 无 The number of area blocks; it is understandable that the statistical range can be within the nine-square grid of the seating area;

[0106] N 干 The region I has the attribute of dryness / wetness as dry clothes. 干 The number;

[0107] N 人 Block I is a region with a wet / dry attribute and a human presence attribute. 人 The number;

[0108] N 湿 The dryness / wetness attribute is the wet clothing attribute I. 湿 The number of region blocks;

[0109] M represents the number of blocks that divide the seating area into;

[0110] a1, a2, a3 and a4, b1, b2, b3 and b4, c1, c2, c3 and c4 are preset weight values ​​located between (0, 1);

[0111] d is the preset temperature difference value.

[0112] In a specific example, the weight values ​​of each formula and the temperature difference value can be set as follows:

[0113] a1=0.6, a2=0.6, a3=0.5, a4=0.2;

[0114] b1=0.8, b2=0.6, b3=0.5, b4=0.3;

[0115] c1=0.6, c2=0.5, c3=0.4, c4=0.2;

[0116] d = 1.5℃.

[0117] Through the above numerical setting, the wet clothes attribute corresponding air supply temperature N 湿 is higher than the dry clothes attribute corresponding air supply humidity N 干 , the influence of air conditioning cold wind directly blowing on the human body to cause wind cold can be reduced, and the wet clothes are blown dry, and the use experience of the person in the seat is improved.

[0118] Step S122, control the air supply port of the vehicle-mounted air conditioner to perform air supply processing on the corresponding air supply area block of the person at the calculated air supply temperature, and continue for a predetermined time (such as 5 seconds).

[0119] Specifically, when the current area block of the air supply port is I 人 , the air supply temperature is adjusted to T 人 ; when the current area block of the air supply port is I 干 , the air supply temperature is adjusted to T 干 ; when the current area block of the air supply port is I 湿 , the air supply temperature is adjusted to T 湿 ; when the current area block of the air supply port is I 无 , the air supply temperature is adjusted to T 无 .

[0120] Further, in the implementation of the embodiments of the present application, some measures described below can also be considered and adopted:

[0121] It can be understood that in the step S11, the work of obtaining the dry and wet degree attribute of each area block can be periodically updated (such as once every 5 seconds); at the same time, the air supply sequence can also be polled with the same period, so that the air conditioning parameters can be dynamically adjusted to further reduce the air conditioning cold wind directly blowing on the human body, and to speed up the blowing of wet clothes, thereby improving the experience. Of course, when the temperature in the vehicle is less than the first temperature threshold (such as 27℃) in any period, the vehicle-mounted air conditioner is immediately stopped for cooling, so that the energy consumption of the vehicle can be dynamically reduced.

[0122] In the embodiments of the present application, the temperature in the vehicle can be controlled to be reduced before the user enters the vehicle in high temperature weather, therefore, the method further comprises: when the weather temperature at the location of the vehicle exceeds the second temperature threshold (such as 30℃), if there is no user in the vehicle, when it is detected that the outdoor temperature is greater than or equal to the third temperature threshold (such as 30℃) and the temperature difference between the outdoor temperature and the indoor temperature is greater than the preset second temperature value (such as 2℃), the vehicle-mounted air conditioner is started to automatically cool, and the temperature difference is kept equal to the second temperature value until the outdoor temperature is less than the third temperature threshold.

[0123] Specifically, first, based on the latitude and longitude information on the vehicle GPS, the city where the vehicle is located is determined to obtain the weather temperature in the weather information of the city where the vehicle is located. Secondly, it is judged whether the weather temperature exceeds the first temperature threshold (such as 30 DEG C). If the weather temperature exceeds the second temperature threshold 30 DEG C, it is determined that it is high temperature weather, so that the inside and outside cameras of the vehicle are started to detect whether there is a user in the vehicle.

[0124] Secondly, when it is detected that there is no user in the vehicle, it is judged whether the outside temperature is greater than or equal to the third temperature threshold (such as 30 DEG C). If the outside temperature >= the third temperature threshold (30 DEG C), it is continued to be judged whether the temperature difference between the outside temperature and the inside temperature is greater than the preset second temperature value (2 DEG C). If the outside temperature - the inside temperature = the temperature difference > the second temperature value 2 DEG C, the vehicle air conditioner is started to automatically cool to control the temperature difference to gradually decrease and keep the temperature difference = the second temperature value 2 DEG C.

[0125] Finally, when it is detected that the outside temperature < the third temperature threshold 30 DEG C, the control of the temperature difference = the second temperature value 2 DEG C by the vehicle air conditioner for automatic cooling is terminated.

[0126] Through such a setting, the use experience of the user can be improved while the energy consumption is reduced.

[0127] As shown in Figure 2 , a detailed flow chart of one specific application scenario of the air supply control method of the vehicle air conditioner provided by the application is shown; the following flow combined Figure 2 with the application scenario is described, which specifically includes the following steps:

[0128] Step 1: Obtain the current vehicle latitude and longitude position L to obtain the real-time weather temperature W of the location of the vehicle, and obtain the inside temperature T 内 , the outside temperature T 外 .

[0129] Step 2: According to the real-time weather temperature W of the location of the vehicle, the first temperature threshold is preset to determine whether the current weather belongs to high temperature weather; if it does not belong to high temperature weather, it jumps to step 8; otherwise, if it belongs to high temperature weather, it continues to execute step 3.

[0130] Step 3: If there is no one in the vehicle, when the outside temperature T 外 >= the third temperature threshold 30 DEG C and the temperature difference T 外 -T 内 between the outside temperature T 外 and the inside temperature T 内 > 2 DEG C, the vehicle air conditioner is automatically started to cool, and the temperature difference T 外 -T 内 = 2 DEG C is kept until the outside temperature T 外Cooling stops when the third temperature threshold of 30°C is reached, thus terminating the control of the aforementioned 2°C temperature difference.

[0131] Step 4: If someone is seated inside the vehicle, then set the temperature inside the vehicle to T. 内 When the second temperature threshold of 27℃ is reached, the vehicle's air conditioning will automatically start to cool the vehicle and will blow air through a swing mode until the interior temperature reaches T. 内 The vehicle's air conditioning will stop working when the second temperature threshold of 27°C is reached.

[0132] Step 5: Obtain an image of the current seat (including the human body) area using the in-vehicle camera. 图 Human body surface temperature T is obtained through infrared sensors. 体 And obtain the current humidity H in the seat area (including the human body) through a humidity sensor. 湿 The coordinates I of the area block with human attributes are updated every 5 seconds using neural network calculation. 人 (Xi, Yi), the coordinates of the region block with the wet clothing attribute. 湿 (Xo, Yo), the coordinates of the region block with the drying attribute. 干 (Xp, Yp).

[0133] The area blocks are divided into nine-square grids based on each seat area. At this time, the coordinate I(X,Y) is the center point of a square block with a variable length of a centimeters. The specific value of a can be defined according to the air conditioning air supply zone.
