[0003] However, the remote control of existing air conditioning systems often has the following problems: the air conditioner is turned on in advance when the user is far away from the vehicle.

[0039] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only 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.

[0040] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0041] In a first aspect, an embodiment of the present application provides an air conditioning control method.

[0042] In one embodiment, referring to Figure 1 , Figure 1 This is a flow chart of an embodiment of the air conditioning control method of the present application.

[0043] like Figure 1 As shown, the air conditioning control method includes:

[0044] Step S10: Determine the power demand based on the difference between the temperature inside the vehicle and the target temperature, the first time, the air density and the volume of the space inside the vehicle, wherein the first time is determined based on the moving distance and speed of the target object within a preset time period.

[0045] It should be noted that the system corresponding to the air conditioning control method in the embodiment of the present application can refer to Figure 2 As shown, specifically, the vehicle-mounted GPS, mobile terminal and cloud server communicate through a wireless network to achieve data exchange and instruction transmission; TBOX (Telematics Box, vehicle bus control unit) collects data from the temperature sensor and human body sensor in the vehicle, and sends the data to the vehicle controller or cloud server for processing; the vehicle controller adjusts the working state of the vehicle according to the received data and sends instructions to the air-conditioning controller; the air-conditioning controller controls the working state of the compressor, PTC (Positive Temperature Coefficient, heater with positive temperature coefficient) and fan according to the received instructions to adjust the vehicle environment; the whole process forms a closed-loop system, in which various parts cooperate with each other to jointly realize air-conditioning control.

[0046] Exemplarily, it should be understood that the target object refers to a person who needs to remotely control the vehicle air conditioner. The specific value of the target temperature can be determined according to the current state of the target object and is not limited here. The temperature inside the vehicle can be measured by the temperature sensor inside the vehicle. The larger the difference between the temperature inside the vehicle and the target temperature, the larger the temperature amplitude that needs to be adjusted, and thus more power is required to achieve temperature regulation. The difference can help the air-conditioning system determine how much energy needs to be output to achieve a comfortable vehicle environment. The first time is used to evaluate the time required for the target object to reach the vehicle, which can be obtained by taking the quotient of the moving distance and speed of the target object within a certain period of time. Air density refers to the mass of air per unit volume, which can be determined based on temperature and air pressure. Lower air density will result in lower heat transfer efficiency. Therefore, this parameter needs to be considered when calculating the power demand to ensure that the calculated power demand can meet the energy required for heating or cooling. The volume of the space inside the vehicle refers to the physical space volume inside the vehicle, usually expressed in cubic meters. A larger space inside the vehicle requires more energy to adjust the temperature.

[0047] Specifically, by comprehensively considering the difference between the temperature inside the car and the target temperature, the speed and distance of the user's movement (i.e. the first time), the air density and the volume of the space inside the car, the air conditioning power required to meet the user's comfort needs can be accurately calculated. By accurately calculating the impact of each parameter, it is possible to determine when and how the air conditioner should be started or adjusted to achieve efficient temperature control. By accurately calculating the required power, the system can start the air conditioner only when it is actually needed, reducing energy waste.

[0048] Step S20: When it is detected that the power demand is greater than or equal to the preset air-conditioning working power, the air-conditioning is adjusted and controlled based on the power demand to achieve temperature adjustment in the vehicle.

[0049] Exemplarily, in the embodiment of the present application, the power demand refers to the energy output level required for current vehicle temperature regulation, which can help the system determine how much energy the air conditioner needs to provide to reach the target temperature; the preset air conditioner operating power refers to the minimum operating power of the air conditioner, which can be determined based on the specifications of the air conditioner and is not limited here.

[0050] Specifically, when the system detects that the power demand reaches or exceeds the preset air conditioning working power, it means that the temperature inside the car needs to be adjusted to reach the target temperature. Therefore, the air conditioner can be adjusted and controlled based on the power demand to ensure that the air conditioner outputs enough cold or hot air to achieve effective adjustment of the temperature inside the car. Precise adjustment can avoid unnecessary energy waste and respond to temperature changes in a timely manner to keep the car environment comfortable.

[0051] The present application determines the power demand through the difference between the temperature inside the vehicle and the target temperature, the first time, the air density and the volume of the space inside the vehicle, wherein the first time is determined based on the moving distance and speed of the target object within a preset time period; only when it is detected that the power demand is greater than or equal to the preset air-conditioning working power, it means that the air-conditioning will not run indiscriminately when the user is far away from the vehicle, but will be turned on and adjusted and controlled only when the user is close to the vehicle, thereby avoiding unnecessary energy waste caused by long-term operation of the air-conditioning, and then the air-conditioning is intelligently adjusted and controlled based on the power demand, so that the temperature inside the vehicle is adjusted to the target temperature as soon as possible, and finally the temperature regulation inside the vehicle is achieved.

[0052] Further, in one embodiment, referring to Figure 3 As shown, before the step of determining the power demand based on the difference between the vehicle interior temperature and the target temperature, the first time, the air density and the volume of the vehicle interior space, the step further includes:

[0053] Step P10: When the moving distance is greater than a preset running distance threshold and the current heart rate of the target object is greater than a preset heart rate threshold, it is determined that the target object is in a running state;

[0054] Step P20: Determine the target temperature corresponding to the current running speed and the current heart rate based on a preset target mapping relationship, where the target mapping relationship is a mapping relationship between the running speed, the heart rate and the temperature.

[0055] Exemplarily, in an embodiment of the present application, the preset running distance threshold refers to the minimum running distance when the target object is judged to be in a running state, and its specific value can be determined according to actual needs and is not limited here; the moving distance is used to determine whether the target object is in a running state, and if it exceeds the running distance threshold, it indicates that the target object is moving quickly; the heart rate can reflect the physiological state of the target object, and an increase in heart rate is usually associated with high-intensity exercise; when the moving distance is greater than the preset running distance threshold and the heart rate exceeds the preset heart rate threshold, the target object is determined to be in a state of motion, wherein the specific value of the preset heart rate threshold can be determined according to actual needs and is not limited here; the target mapping relationship is used to describe the correlation between running speed, heart rate and temperature, and the target mapping relationship can be obtained through experimental calibration, which is not limited here, and can help the system adjust the target temperature according to the current state of motion of the target object to ensure the comfort of the user.

[0056] Specifically, the target object's moving distance and heart rate can be detected to determine whether it is in a running state; if the target object is in a running state, the system can determine the target temperature corresponding to the current running speed and heart rate based on the target mapping relationship, and then adjust the temperature based on the target temperature. It can be understood that the target temperature is adjusted in time according to the user's exercise state to improve the user experience; and the system can automatically adjust according to the user's physiological state to provide personalized services.

[0057] Further, in one embodiment, the power demand is determined based on the difference between the vehicle interior temperature and the target temperature, the first time, the air density, and the volume of the vehicle interior space, including:

[0058] The difference between the vehicle interior temperature and the target temperature, the first time, the air density, and the volume of the vehicle interior space are substituted into a first calculation formula to obtain the power demand. The first calculation formula is as follows:

[0059]

[0060] Wherein, t1 is the first time; ρ1 is the air density; V1 is the volume of the interior space; TC is the interior temperature; TS is the target temperature; and P0 is the power demand.

[0061] Exemplarily, in the embodiment of the present application, the vehicle interior temperature TC, the target temperature TS, the first time t1, the air density ρ1 and the vehicle interior space volume V1 are substituted into the following calculation formula to obtain the power demand P0, which is as follows:

[0062]

[0063] Further, in one embodiment, referring to Figure 4 As shown, the regulating and controlling of the air conditioner based on the power demand includes:

[0064] Step S201: if the power demand is greater than a preset power threshold, the air conditioner is regulated and controlled according to the preset power threshold;

[0065] Step S202: If the power demand is not greater than the preset power threshold, the air conditioner is adjusted and controlled based on the target parameters and the power demand, and the target parameters include the in-vehicle space influencing factor value, the in-vehicle space volume, the solar heat radiation influencing factor value, the sum of all glass areas, the vehicle type sealing and insulation effect factor value, the first in-vehicle heat load ratio and the second in-vehicle heat load ratio.

[0066] Exemplarily, in the embodiment of the present application, the preset power threshold is used as a reference for adjustment and control to ensure that the air conditioner works within a safe and effective range. Its specific value can be determined according to actual needs, but it should be noted that it has different meanings in different scenarios (cooling scenario and heating scenario). In the cooling scenario, the preset power threshold refers to the maximum cooling power, and in the heating scenario, the preset power threshold refers to the maximum heating power; the in-vehicle space influencing factor value refers to various structural factors that affect the in-vehicle temperature, which can be comprehensively evaluated by the automobile manufacturer based on the overall design and space utilization of the vehicle. For example, the in-vehicle space influencing factor value can be preferably 450W / m^3; the in-vehicle space volume reflects the overall size of the in-vehicle space and can be calculated by measuring the length, width and height of the vehicle; the solar thermal radiation influencing factor value reflects the degree of solar thermal radiation received by the vehicle in the sun, which has an important impact on the in-vehicle temperature and the load of the air-conditioning system. It is mainly affected by the intensity of solar radiation, the surface material of the vehicle, the type and color of the window glass, etc., and can be obtained through experimental measurement or simulation calculation. For example, the solar thermal radiation influencing factor value can be preferably 900W / m^2.

[0067] Among them, the sum of all glass areas affects heat transfer and the temperature inside the car, which can be obtained by measuring the area of ​​all glass parts such as windows and windshields on the vehicle and summing them up; the sealing and insulation effect factor value of the vehicle model reflects the ability of the vehicle to maintain the temperature and humidity inside the car after closing the windows and doors. It is mainly affected by factors such as vehicle sealing performance, body material, window glass type and sealing strips, and can also be obtained through experimental measurement or simulation calculation. For example, for a fiberglass roof, a floor with insulation material filling thickness greater than 20mm, good side insulation, and good sealing of glass and doors, For a good car model, the sealing and thermal insulation effect factor value of the car model can be preferably taken as 1W / m^2; the in-car heat load ratio refers to the proportion of heat from different sources in the in-car heat load, which is related to factors such as the car model, vehicle configuration, and usage environment, and can be obtained through experimental measurement and data analysis. The in-car heat load ratio includes the first in-car heat load ratio (such as passengers, electronic equipment and other in-car heat sources) and the second in-car heat load ratio (such as temperature, humidity and other external environmental factors). For example, the first in-car heat load ratio can be preferably taken as 0.1, and the second in-car heat load ratio can be preferably taken as 0.08.

[0068] Specifically, since the air conditioning control principles corresponding to the cooling scenario and the heating scenario are the same, for the sake of simplicity of description, the following embodiments will be described in the cooling scenario: different air conditioning adjustment and control strategies are formulated based on the comparison between the power demand and the maximum cooling power. When the power demand is higher than the maximum cooling power, it means that the temperature adjustment has exceeded the maximum cooling capacity. At this time, the air conditioner will work at the maximum cooling power to ensure rapid response and meet the temperature adjustment requirements; when the power demand does not exceed the maximum cooling power, the system can comprehensively consider the target parameters (interior space influencing factor value, interior space volume, solar thermal radiation influencing factor value, total of all glass areas, vehicle type sealing and insulation effect factor value, first interior heat load ratio and second interior heat load ratio) and power demand to adjust and control the air conditioner, ensuring that the air conditioner is started at the right time and with the right power, so that the interior temperature quickly reaches the target temperature, thereby optimizing energy efficiency and improving comfort.

[0069] Furthermore, in one embodiment, the step of adjusting and controlling the air conditioner based on the target parameter and the power demand includes:

[0070] Substitute the influencing factor value of the interior space, the volume of the interior space, the influencing factor value of solar heat radiation, the sum of the areas of all windows and all glass, the sealing and thermal insulation effect factor value of the vehicle model, the first in-vehicle heat load ratio, the second in-vehicle heat load ratio and the power demand into the calculation formula to obtain the first power, and adjust and control the air conditioner based on the first power;

[0071] The calculation formula of the first power is:

[0072] P1=(A1*V1*K1+A2*S*K2)*A3+P0

[0073] Wherein, A1 is the influencing factor of the interior space; A2 is the influencing factor of solar heat radiation; S is the sum of the areas of all windows and all glass; A3 is the sealing and thermal insulation effect factor of the vehicle model; V1 is the volume of the interior space; K1 is the first interior heat load ratio; K2 is the second interior heat load ratio; P1 is the first power; and P0 is the power demand.

[0074] Exemplarily, in the embodiment of the present application, the in-vehicle space influencing factor value A1, the in-vehicle space volume V1, the solar heat radiation influencing factor value A2, the total area S of all windows and all glass, the vehicle type sealing and heat preservation effect factor value A3, the first in-vehicle heat load ratio K1, the second in-vehicle heat load ratio K2 and the power demand P0 are substituted into the following first calculation formula to obtain the first power P1, and the air conditioner is adjusted and controlled based on the first power. If cooling is required, the compressor can be started according to the required cooling capacity corresponding to the first power to increase the circulation of the refrigerant, so that the temperature in the car is quickly reduced to the target temperature; if heating is required, the PTC can be started according to the required heating capacity corresponding to the first power to increase the heat, so that the temperature in the car is quickly increased to the target temperature, thereby achieving rapid adjustment of the temperature in the car. Among them, the calculation formula of the first power is:

[0075] P1=(A1*V1*K1+A2*S*K2)*A3+P0.

[0076] It should be noted that when the driver and passengers enter the car, the human body sensor can also be used to determine whether the driver and passengers are sweating (a decrease in human body resistance means sweating); if the driver and passengers are sweating, the fan can be controlled to reduce the air volume until the human body resistance returns to normal.

[0077] Furthermore, in one embodiment, before the step of determining the power demand based on the difference between the vehicle interior temperature and the target temperature, the first time, the air density and the volume of the vehicle interior space, the step further includes:

[0078] When it is detected that the target object is moving toward the target vehicle and the moving distance of the target object within the preset time period is not less than the preset distance threshold, the step of determining the power demand based on the difference between the interior temperature and the target temperature, the first time, the air density and the interior space volume is executed.

[0079] Exemplarily, in an embodiment of the present application, a preset distance threshold is used to determine whether a target object is close to a vehicle, and its specific value can be determined according to actual needs and is not limited here; the specific value of the preset angle threshold can be determined according to actual needs and is not limited here.

[0080] Specifically, the position X1 of the target object at the previous moment and the position X2 at the current moment can be obtained through a mobile terminal integrated with GPS, and the displacement direction of the target object can be obtained by connecting the lines. The angle between the displacement direction and the direction of the line connecting the person and the vehicle can be determined. If the angle is less than the preset angle threshold, it means that the person is moving towards the direction of the vehicle; when the person moves towards the direction of the vehicle and the moving distance within a certain period of time is greater than or equal to the preset distance threshold, it means that the person is approaching the vehicle at a certain speed. At this time, the collected data can be fed back to the cloud server through the mobile terminal, and then transmitted to the TBOX and the vehicle controller through the cloud server to realize the automatic execution of the air conditioning control strategy.

[0081] Furthermore, in one embodiment, after the step of adjusting and controlling the air conditioner based on the power demand, the method further includes:

[0082] When it is detected that the target object moves in the opposite direction of the target vehicle and the moving distance of the target object within a preset time period is less than a preset distance threshold, the air conditioner is controlled to be turned off.

[0083] Exemplarily, in an embodiment of the present application, specifically, after the air conditioner is turned on, the position X1 of the target object at the previous moment and the position X2 at the current moment can be obtained through a mobile terminal integrated with GPS, and the displacement direction of the target object can be obtained by connecting the lines, and the angle between the displacement direction and the direction of the line connecting the person and the vehicle can be judged. If the angle is greater than or equal to a preset angle threshold, it means that the person is moving in the opposite direction of the vehicle; when the person moves in the opposite direction of the vehicle and the moving distance within a certain time period is less than a preset distance threshold, it means that the person is moving away from the vehicle at a certain speed. At this time, the air conditioner can be controlled to be turned off based on the air conditioner controller to avoid energy waste.

[0084] In a second aspect, an embodiment of the present application further provides an air conditioning control system, the air conditioning control system comprising:

[0085] A first processing module, which is used to determine the power demand based on the difference between the temperature inside the vehicle and the target temperature, the first time, the air density and the volume of the space inside the vehicle, wherein the first time is determined based on the moving distance and speed of the target object within a preset time period;

[0086] A second processing module is used to adjust and control the air conditioner based on the power demand to achieve temperature adjustment in the vehicle when it is detected that the power demand is greater than or equal to the preset air conditioner working power;

[0087] It should be noted that the air-conditioning control system includes a vehicle-mounted GPS, a mobile terminal, a cloud server, a TBOX, an in-vehicle temperature sensor, a human body sensor, a vehicle controller, an air-conditioning controller, a compressor, a PTC, and a fan, wherein the first processing module and the second processing module can be integrated on the air-conditioning controller.

[0088] Furthermore, in one embodiment, the first module is specifically used for:

[0089] When the moving distance is greater than a preset running distance threshold and the current heart rate of the target object is greater than a preset heart rate threshold, it is determined that the target object is in a running state;

[0091] Furthermore, in one embodiment, the first module is further configured to:

[0092] The difference between the vehicle interior temperature and the target temperature, the first time, the air density, and the volume of the vehicle interior space are substituted into a first calculation formula to obtain the power demand. The first calculation formula is as follows:

[0094] Wherein, t1 is the first time; ρ1 is the air density; V1 is the volume of the interior space; TC is the interior temperature; TS is the target temperature; and P0 is the power demand.

[0100] The calculation formula of the first power is:

[0105] Furthermore, in one embodiment, the second module is further configured to:

[0106] When it is detected that the target object moves in the opposite direction of the target vehicle and the moving distance of the target object within a preset time period is less than a preset distance threshold, the air conditioner is controlled to be turned off.

[0107] The present application determines the power demand through the difference between the temperature inside the vehicle and the target temperature, the first time, the air density and the volume of the space inside the vehicle, wherein the first time is determined based on the moving distance and speed of the target object within a preset time period; only when it is detected that the power demand is greater than or equal to the preset air-conditioning working power, it means that the air-conditioning will not run indiscriminately when the user is far away from the vehicle, but will be turned on and adjusted and controlled only when the user is close to the vehicle, thereby avoiding unnecessary energy waste caused by long-term operation of the air-conditioning, and then the air-conditioning is intelligently adjusted and controlled based on the power demand, so that the temperature inside the vehicle is adjusted to the target temperature as soon as possible, and finally the temperature regulation inside the vehicle is achieved.
