[0049] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0050] An air conditioner is a device used to adjust the ambient temperature. It can cool the environment by blowing out low-temperature air from the air outlet, or warm the environment by blowing out high-temperature air from the air outlet.

[0051] In the related art, after receiving the required temperature or required wind speed set by the user, the air conditioner will control the air conditioner to output the airflow with the required wind speed or temperature from the air outlet to meet the user's needs. However, after the airflow is blown out from the air outlet, the wind speed or temperature will change with the change of position during the flow process, which will cause the temperature or wind speed actually felt by the user to be different from the required temperature or wind speed, reducing the control accuracy of the air conditioner.

[0052] Based on this, in order to solve the problem of how to improve the control accuracy of the air conditioner, the present application provides a control method, system and vehicle for an air conditioner. When the air conditioner is running, the straight-line distance between the air outlet and the wind receiving object and the required characteristic parameters of the wind receiving object are first determined. Subsequently, the wind condition change law determined based on the shape of the air outlet is obtained, so that the characteristic parameters of the airflow at the air outlet are controlled based on the straight-line distance, the required characteristic parameters and the wind condition change law. The present application uses the wind condition change law to grasp the change law of characteristic parameters such as the temperature and wind speed of the airflow during the flow of the airflow with distance, and further determines through the straight-line distance that when the airflow is delivered at the air outlet with what characteristic parameters, it can meet the needs of the wind receiving object, thereby ensuring that the wind receiving object can feel the required temperature and wind speed no matter where it is, ensuring the identity of its feelings and needs, and improving the control accuracy of the air conditioner. The specific method is as follows:

[0053] The first aspect of the present application proposes an embodiment, such as Figure 1 As shown in the step diagram of a control method for an air conditioner, the method is applied to a vehicle, specifically to an on-board controller of the vehicle, and the main steps include:

[0054] Step S101, when the air conditioner is running, determining the straight-line distance between the air outlet and the wind receiving object and the demand characteristic parameters.

[0055] The demand characteristic parameters include characteristic parameters required by the windward object, and the characteristic parameters include temperature and / or wind speed.

[0056] An air conditioner refers to a device that regulates the ambient temperature. In a narrow sense, an air conditioner is a device composed of components such as a condenser, a compressor, and an evaporator. In a broad sense, an air conditioner (that is, the air conditioner described in this application) can also be all devices that have a regulating effect on the ambient temperature. For example, when cooling the vehicle cab, it can be achieved through an air conditioner in a narrow sense composed of a condenser, a compressor, and an evaporator, but when heating the vehicle cab, it is usually achieved through an additional heating device, such as a heating wire. Since the heating device is also used to regulate the temperature of the vehicle cab, the heating device can also be regarded as a part of the air conditioner described in this application.

[0057] The wind-receiving object refers to an object with temperature regulation requirements within the temperature regulation range of the air conditioner. Specifically, it can be a human, an animal, a server or other objects with specific temperature requirements. The characteristic parameters may include temperature, or wind speed, or temperature and wind speed. Correspondingly, the demand characteristic parameters may include the required temperature, or the required wind speed, or the required temperature and the required wind speed. In an optional embodiment, the demand characteristic parameters can be manually input into the vehicle controller through a physical button set on the air conditioner.

[0058] The straight-line distance between the air outlet and the windward object may be the straight-line distance between the air outlet and the closest part of the windward object, or the straight-line distance between the air outlet and any part of the windward object. For example, when the windward object is a human body, it may be the straight-line distance between the air outlet and the human face, or the straight-line distance between the air outlet and the human hand. In an optional embodiment, the straight-line distance between the air outlet and the windward object may be measured by an infrared rangefinder disposed at the air outlet.

[0059] Step S102, obtaining the wind condition change law corresponding to the air outlet, and controlling the characteristic parameters of the airflow at the air outlet based on the straight-line distance, the wind condition change law and the demand characteristic parameters.

[0060] The wind condition variation law is determined according to the shape of the air outlet, and the wind condition variation law is used to characterize the variation relationship between the characteristic parameters of the airflow and the distance.

[0061] The wind condition change law can be in the form of a functional relationship or a mapping relationship table. Taking the wind condition change law as a functional relationship as an example, the wind condition change law is illustrated. Refer to the wind condition change functional relationship of temperature shown in formula (1) and the wind condition function change relationship of wind speed shown in formula (2).

[0062]

[0063] Among them, Z0, B, C, D, E, F, G are all constants, X is the straight-line distance, T0 is the temperature of the airflow at the outlet, T x It is the temperature of the airflow at the windward object.

[0064]

[0065] Among them, Z0, A 01 , B 01 , B 02 , B 03 , A1, A2, A3, B1, B2 are all constants, X is the straight-line distance, V0 is the wind speed at the outlet, V x It is the wind speed at the windward object.

[0066] Taking the wind condition change law as a functional relationship as an example, after obtaining the straight-line distance, wind condition change law and demand characteristic parameters, the straight-line distance and the demand temperature in the demand characteristic parameters are substituted into formula (1) to obtain T0 corresponding to the demand temperature, thereby controlling the temperature of the airflow delivered from the air outlet at the air outlet to be T0 corresponding to the demand temperature.

[0067] Similarly, by substituting the straight-line distance and the required wind speed in the demand characteristic parameter into formula (2), V0 corresponding to the required wind speed can be obtained, thereby controlling the air flow delivered from the air outlet to be V0 corresponding to the required wind speed at the fan at the air outlet.

[0068] In an optional embodiment, the temperature of the airflow delivered from the air outlet at the air outlet can be controlled by controlling the power of the air-conditioning compressor, and the wind speed of the airflow delivered from the air outlet at the air outlet can be controlled by controlling the power of the air-conditioning blower.

[0069] In an optional embodiment, the wind condition change law corresponding to the air outlet can be predetermined based on the shape of the air outlet during the factory setting stage and pre-stored in the storage unit of the vehicle controller. The shape of the air outlet may include circular, square, C-shaped, round, etc. The values ​​of the constants in formula (1) and formula (2) are different for different air outlet shapes.

[0070] In an optional implementation, the air conditioner may be provided with a plurality of air outlets of different shapes. During the operation of the air conditioner, the wind condition change rules corresponding to the shapes of the air outlets are respectively obtained.

[0071] In this embodiment, when the air conditioner is running, the straight-line distance between the air outlet and the object receiving the wind and the required characteristic parameters of the object receiving the wind are first determined. Subsequently, the wind condition change law determined based on the shape of the air outlet is obtained, and the characteristic parameters of the airflow at the air outlet are controlled based on the straight-line distance, the required characteristic parameters and the wind condition change law. This embodiment uses the wind condition change law to grasp the change law of characteristic parameters such as the temperature and wind speed of the airflow during the flow of the airflow with the distance, and further determines through the straight-line distance that when the airflow is sent out at the air outlet with what characteristic parameters, the needs of the object receiving the wind can be met, thereby ensuring that the object receiving the wind can feel the temperature and wind speed it needs no matter where it is, ensuring the identity of its feelings and needs, and improving the control accuracy of the air conditioner.

[0072] Optionally, refer to Figure 2 A method step diagram of controlling characteristic parameters of airflow at an air outlet is shown, wherein step S102 controls the characteristic parameters of the airflow at the air outlet based on the straight-line distance, the wind condition change law, and the required characteristic parameters, and specifically includes the following steps:

[0073] Step S11, obtaining actual characteristic parameters of the airflow at the air outlet.

[0074] Step S12, determining the actual characteristic parameters of the airflow at the wind receiving object based on the actual characteristic parameters of the airflow at the air outlet, the wind condition change rule and the straight-line distance.

[0075] Step S13, based on the actual characteristic parameters of the airflow at the wind receiving object, correct the actual characteristic parameters of the airflow at the air outlet, so that the actual characteristic parameters of the airflow at the wind receiving object are the required characteristic parameters after correction.

[0076] The actual characteristic parameter of the airflow at the air outlet refers to the characteristic parameter measured at the air outlet by a sensor or other device. The actual characteristic parameter may be the actual temperature, or the actual wind speed, or the actual temperature and the actual wind speed. In an optional embodiment, the actual wind speed may be measured by an air velocity meter installed at the air outlet, and the actual temperature may be measured by a temperature sensor installed at the air outlet.

[0077] After measuring the actual characteristic parameters, the actual characteristic parameters and the straight-line distance can be substituted into the above formula (1) or formula (2) to calculate the actual characteristic parameters of the airflow at the windward object. Subsequently, the actual characteristic parameters of the airflow at the windward object are compared with the required characteristic parameters, so that the actual characteristic parameters of the airflow at the air outlet are corrected based on the actual characteristic parameters of the airflow at the windward object, so that the actual characteristic parameters of the airflow at the windward object are corrected to the required characteristic parameters.

[0078] Specifically, the correction process may include, if the actual characteristic parameter at the windward object is smaller than the required characteristic parameter, then appropriately increasing the actual characteristic parameter of the airflow at the air outlet; if the actual characteristic parameter at the windward object is larger than the required characteristic parameter, then appropriately reducing the actual characteristic parameter of the airflow at the air outlet.

[0079] This embodiment first determines the actual characteristic parameters of the airflow at the wind receiving object through the actual characteristic parameters at the air outlet, and then corrects the actual characteristic parameters of the airflow at the air outlet based on the actual characteristic parameters of the airflow at the wind receiving object, and finally makes the characteristic parameters of the airflow at the wind receiving object the required characteristic parameters after correction. This embodiment controls the characteristic parameters of the airflow at the air outlet by feedback correction, which can effectively avoid wind speed and temperature fluctuations caused by unstable blower or compressor power, thereby further improving the accuracy of air conditioning control.

[0080] Optionally, the object receiving the wind is a living body, referring to Figure 3 A method step diagram for determining demand characteristic parameters is shown, and the steps of determining demand characteristic parameters specifically include:

[0081] Step S21, obtaining physiological information of the wind receiving object.

[0082] The physiological information includes at least one of weight, gender and age.

[0083] Step S22: determining the demand characteristic parameters based on the physiological information of the object being received.

[0084] When the object being affected by the wind is a living thing, the required characteristic parameters can be determined intelligently. The object being affected by the wind can be a passenger or a pet.

[0085] The physiological information of the object may be at least one of weight, gender and age. In an optional embodiment, the weight, gender and age may be pre-set in the vehicle controller. Alternatively, the information may be acquired through a weight sensor or an image acquisition device.

[0086] The difference in physiological information of wind objects represents the different perceptions of wind objects for the same temperature and wind speed. For example, taking the wind objects as passengers, in an environment with the same temperature and wind speed, male passengers will subjectively think it is hotter than female passengers, young passengers will subjectively think it is hotter than old passengers, and heavy passengers will subjectively think it is hotter than light passengers.

[0087] Therefore, the temperature or wind speed that makes the object feel comfortable can be determined based on the physiological information of the object being winded, thereby determining the required characteristic parameters.

[0088] In this embodiment, when the object being affected is a living body, the demand characteristic parameters are determined through the physiological information of the object being affected, and automatic control of the air conditioner can be achieved without user input, thereby improving the intelligence of the air conditioner control.

[0089] Optionally, refer to Figure 4 The step diagram of a method for determining a required characteristic parameter based on a characteristic parameter mapping table is shown, wherein the step S22 determines the required characteristic parameter based on the physiological information of the object receiving the wind, and specifically includes the following steps:

[0090] Step S31, obtaining a characteristic parameter mapping table.

[0091] The characteristic parameter mapping table includes different preset characteristic parameters corresponding to different physiological information.

[0092] Step S32: determining the preset characteristic parameters corresponding to the physiological information of the windward object in the characteristic parameter table as the required characteristic parameters.

[0093] The characteristic parameter mapping table may be pre-stored in a storage unit on the vehicle-mounted controller. Taking the physiological information as body weight as an example, the characteristic parameter mapping table may be in the form of the following Table 1.

[0094] Table 1

[0095] Weight(kg) Wind speed (m / s) Temperature(℃) 30 0.15 25 50 0.18 24 60 0.20 23 80 0.24 22

[0096] For example, if the weight of the object affected by the wind is collected to be 60kg, the weight of the object affected by the wind can be compared with the characteristic parameter mapping table shown in Table 1. In Table 1, the wind speed corresponding to the weight of 60kg is 0.2m / s and the temperature is 23°C. Therefore, the required characteristic parameters can be determined to be 0.2m / s and 23°C.

[0097] This embodiment determines the demand characteristic parameters through the characteristic parameter mapping table, which can simplify the process of determining the demand characteristic parameters, thereby reducing the computing resources required for determining the demand characteristic parameters, and further improving the computing performance of the vehicle controller.

[0098] Optionally, before obtaining the wind condition variation law corresponding to the air outlet in step S102, and controlling the characteristic parameters of the airflow at the air outlet based on the straight-line distance, the wind condition variation law and the demand characteristic parameters, the method further includes:

[0099] Determine the operating mode of the air conditioner. The operating mode includes a heating mode or a cooling mode.

[0100] Step S102 specifically includes, when the operating mode is the cooling mode, obtaining the wind condition change law corresponding to the air outlet, and controlling the characteristic parameters of the airflow at the air outlet based on the straight-line distance, the wind condition change law and the demand characteristic parameters.

[0101] The operating modes of the air conditioner include cooling mode and heating mode. Cooling mode refers to the mode in which the air conditioner lowers the ambient temperature, and heating mode refers to the mode in which the air conditioner raises the ambient temperature. Considering that hot air is lighter than cold air, in order to ensure uniform distribution of heat in the space, the air conditioner usually outputs airflow toward the ground in heating mode. In other words, in heating mode, the airflow output from the air outlet does not reach the wind receiving object through linear motion, so the airflow output from the air outlet rarely conforms to the law of wind condition changes.

[0102] It can be seen that when the air conditioner is in heating mode, the control efficiency of the characteristic parameter based on the wind condition change law is low. Therefore, before executing step S102, the operation mode of the air conditioner can be judged first, and then the characteristic parameter can be controlled based on the wind condition change law when the operation mode of the air conditioner is cooling mode. If the operation mode of the air conditioner is heating mode, step S102 is not executed.

[0103] Due to the limitation of the principle and structure of the vehicle air conditioner itself, the airflow delivered from the air outlet in the heating mode cannot change the wind speed or temperature according to the relatively stable wind condition change law as in the cooling mode. Therefore, the control accuracy of the characteristic parameters in the heating mode by the method described in this application will be lower than the control accuracy in the cooling mode. It can be seen that before controlling the characteristic parameters based on the wind condition change law, this embodiment first determines the operation mode of the air conditioner, so that the vehicle can control the characteristic parameters based on the wind condition change law only in the cooling mode with higher control accuracy, thereby reducing the computing resource occupation of the vehicle controller, and further optimizing the control method.

[0104] Optionally, refer to Figure 5 A method step diagram for determining the law of wind condition changes is shown, and the steps of obtaining the law of wind condition changes include:

[0105] Step S41 , acquiring characteristic parameters of the airflow multiple times at multiple positions at different distances from the air outlet.

[0106] Wherein, the airflow is sent out from the air outlet with different preset characteristic parameters each time it is acquired.

[0107] Step S42, determining the wind condition change pattern based on the characteristic parameters of the airflow obtained multiple times and the shape of the air outlet.

[0108] The step of acquiring the wind condition variation pattern may be performed during the factory setting stage of the vehicle or the air conditioner, or may be performed in response to the operation of the air conditioner.

[0109] The steps of obtaining the wind condition change rule are described with a specific example. The multiple positions at different distances from the air outlet may be 15 cm from the air outlet, 20 cm from the air outlet, and 25 cm from the air outlet.

[0110] During the first acquisition, the airflow is controlled to be sent out from the air outlet at a wind speed of 0.35 m / s and a temperature of 22°C, and the wind speed and temperature of the airflow are respectively obtained at 15 cm from the air outlet, 20 cm from the air outlet, and 25 cm from the air outlet. During the second acquisition, the airflow is controlled to be sent out from the air outlet at a wind speed of 0.45 m / s and a temperature of 20°C, and the wind speed and temperature of the airflow are respectively obtained at 15 cm from the air outlet, 20 cm from the air outlet, and 25 cm from the air outlet. During the third acquisition, the airflow is controlled to be sent out from the air outlet at a wind speed of 0.50 m / s and a temperature of 18°C, and the wind speed and temperature of the airflow are respectively obtained at 15 cm from the air outlet, 20 cm from the air outlet, and 25 cm from the air outlet.

[0111] Subsequently, the wind speed and temperature obtained three times at 15 cm, 20 cm, and 25 cm from the air outlet are processed to obtain a functional relationship or a mapping relationship table that characterizes the law of wind condition changes.

[0112] This embodiment determines the wind condition change law of the air outlet by collecting characteristic parameters multiple times at different positions, thereby improving the authenticity of the wind condition change law. At the same time, compared with the method of determining the wind condition change law through mathematical modeling, it avoids a large number of mathematical calculations and improves the efficiency of determining the wind condition change law.

[0113] Optionally, refer to Figure 6 A method step diagram of controlling the output direction of airflow is shown, wherein the step S102 of controlling the characteristic parameters of the airflow at the air outlet specifically includes the following steps:

[0114] Step S51, obtaining the target position of the wind receiving object relative to the air outlet.

[0115] Step S52, controlling characteristic parameters of the airflow at the air outlet, and controlling the airflow to be sent toward the target direction.

[0116] The target position of the windward object relative to the air outlet refers to the direction of the windward object relative to the air outlet. In an optional embodiment, the target position of the windward object relative to the air outlet can be represented by the angle between the line connecting the windward object and the air outlet and the coordinate axis in the coordinate system.

[0117] In an optional embodiment, a wind grille can be installed in the channel of the air outlet, and the airflow direction can be controlled by adjusting the angle of the wind grille. Specifically, the wind grille can be driven by a small motor, and the angle of the wind grille can be changed by rotating the output shaft of the small motor.

[0118] When controlling the characteristic parameters of the airflow at the air outlet, this embodiment controls the direction in which the airflow is delivered according to the target position of the wind receiving object relative to the air outlet, so that the distance the airflow flows to the wind receiving object is exactly the straight-line distance between the wind receiving object and the air outlet, thereby further ensuring the accuracy of air-conditioning control.

[0119] Optionally, there are multiple wind receiving objects, refer to Figure 7 The step diagram of an air conditioning control method for supplying air to multiple wind receiving objects is shown, and step S102 controls the characteristic parameters of the airflow at the air outlet based on the straight-line distance, the wind condition change law, and the demand characteristic parameters, and specifically includes the following steps:

[0120] Step S61, determining the straight-line distances between each of the plurality of wind receiving objects and the air outlet.

[0121] Step S62, controlling the characteristic parameters of the airflow at the air outlet based on the average values ​​of the plurality of straight-line distances, the wind condition variation pattern, and the required characteristic parameters.

[0122] When there are multiple wind receiving objects, in order to ensure that the wind receiving objects feel the air evenly, the straight-line distances between the multiple wind receiving objects and the air outlet can be determined first, and then the characteristic parameters of the airflow at the air outlet can be controlled based on the average value of the multiple straight-line distances, the law of wind condition changes and the required characteristic parameters.

[0123] Taking the wind condition change law as a functional relationship as an example, the wind condition change law is illustrated. Refer to the wind condition change functional relationship of temperature shown in formula (3) and the wind condition change functional relationship of wind speed shown in formula (4).

[0128] After obtaining the average value of multiple straight-line distances, the average value of multiple straight-line distances and the required characteristic parameters are substituted into the above formula (3) and formula (4) to obtain the characteristic parameters of the airflow at the air outlet.

[0129] In this embodiment, when there are multiple wind receiving objects, the characteristic parameters of the airflow at the air outlet are controlled by taking the average value of the straight-line distances between the multiple wind receiving objects and the air outlet, thereby avoiding extreme sensations of individual wind receiving objects and effectively ensuring the uniformity of the sensations of the multiple wind receiving objects.
