[0002] In related technologies, rear-row air conditioning controls the flow of refrigerant to the rear-row evaporator by controlling the opening and closing of valves connected to the rear-row evaporator, thus determining whether the evaporator needs cooling. The system determines whether to open the valves based on the temperature value output by the rear-row temperature sensor. If the temperature value is too high, the valves open to cool the rear air; if the temperature value is too low, the valves close. This frequent opening and closing of the valves connected to the rear-row evaporator can easily cause wear and leakage on the sealing surfaces, increasing fluid resistance. Summary of the Invention

[0027] To better understand the technical solution of this application, the technical solution of this application will be described in detail below with reference to the accompanying drawings.

Similarly, "a" or "one," and similar terms do not indicate a quantity limitation, but rather indicate the presence of at least one; "multiple" indicates two or more.

[0030] The in-vehicle temperature regulation method of this application will be described in detail below with reference to the accompanying drawings.
[0031] Automotive thermal management systems are primarily used to manage cooling and heating to meet the overall cooling and heating needs of the vehicle, such as the cooling / heating requirements of the cabin, the cooling requirements of the motor, and the heating / cooling requirements of the battery. A portion of the cooling / heating is supplied through methods such as operating the refrigerant circulation loop, starting the heater, and utilizing the cooling capacity of the coolant itself, while some heat is obtained by recovering cooling / heat from other components. Distributing energy among certain components of the automotive thermal management system constitutes a method for regulating the vehicle's interior temperature. It is understood that the components and their locations involved in the interior temperature regulation method can be adjusted according to actual needs without affecting their functionality.
[0032] According to a specific embodiment of the in-vehicle temperature regulation method of this application, such as Figure 1As shown, the front air conditioner 30 includes a front evaporator 31, and the rear air conditioner 40 includes a rear evaporator 41. The front evaporator 31 and the rear evaporator 41 are connected in parallel. The valve 42 connected to the rear evaporator 41 is used to control whether the refrigerant flows into the rear evaporator 41.
[0033] like Figure 2 As shown, the in-vehicle temperature adjustment method includes steps S100 to S200.
[0034] Step S100: Receive the signal to turn on the rear air conditioning and determine the seasonal mode as spring / autumn mode or summer mode based on the ambient temperature.
[0035] In step S200, when the difference between the rear seat interior temperature correction value and the rear seat set temperature is greater than the first temperature threshold, the valve 42 connected to the rear evaporator is opened; when the difference between the rear seat interior temperature correction value and the rear seat set temperature is less than or equal to the first temperature threshold and greater than the second temperature threshold, the valve 42 connected to the rear evaporator is opened, and the airflow of the rear air conditioning 40 is limited; when the difference between the rear seat interior temperature correction value and the rear seat set temperature is less than or equal to the second temperature threshold, the valve 42 connected to the rear evaporator is closed; wherein, the second temperature threshold is less than the first temperature threshold.
[0036] This application uses the comparison between the rear seat interior temperature correction value and the rear seat set temperature to determine whether the valve 42 connected to the rear evaporator is open. When the rear seat interior temperature correction value is close to the rear seat set temperature, the air outlet temperature of the rear air conditioner 40 is first adjusted by limiting the air outlet volume of the rear air conditioner 40, which can reduce the number of times the valve 42 connected to the rear evaporator is frequently opened and closed.
[0037] In some embodiments, such as Figure 3 As shown, step S200 includes step S210.
[0038] Step S210: When the difference between the rear seat interior temperature correction value and the rear seat set temperature is greater than the first temperature threshold, open valve 42 connected to the rear evaporator; when the difference between the rear seat interior temperature correction value and the rear seat set temperature is less than or equal to the first temperature threshold and greater than the second temperature threshold, open valve 42 connected to the rear evaporator and limit the airflow of the rear air conditioner 40; when the difference between the rear seat interior temperature correction value and the rear seat set temperature is less than or equal to the second temperature threshold and greater than the third temperature threshold, close valve 42 connected to the rear evaporator and limit the airflow of the rear air conditioner 40; when the difference between the rear seat interior temperature correction value and the rear seat set temperature is less than or equal to the third temperature threshold, close valve 42 connected to the rear evaporator; wherein, the third temperature threshold is less than the second temperature threshold, and the second temperature threshold is less than the first temperature threshold.
[0039] In step S210, the rear passenger cabin temperature correction value is calculated based on the temperature value output by the rear passenger cabin temperature sensor, taking into account the in-vehicle load and external load, to determine a value representing the rear head temperature. This value is then used as a reference to control the operation of the valve 42 connected to the rear evaporator, as well as the operation of components related to the airflow of the rear air conditioning 40. The method for calculating the rear head temperature can be selected according to actual needs; for example, it can be calculated using a human thermal comfort calculation model, but this application is not limited to this.
[0040] The system controls the valve 42 connected to the rear evaporator based on a comparison between the rear passenger cabin temperature correction value and the set rear passenger temperature. When the rear passenger cabin temperature is too high, the valve 42 opens to cool the rear passengers; when the rear passenger cabin temperature is too low, the valve closes to prevent over-adjustment of the rear passenger cabin temperature. When the rear passenger cabin temperature correction value is close to the set rear passenger temperature, the airflow is reduced first, which reduces the frequency of valve 42's opening and closing, thus reducing the probability of fluctuations in the outlet air temperature when valve 42 is switched on and off. By limiting the airflow to reduce outlet air temperature fluctuations and slowly adjusting the cabin temperature, the probability of outlet air temperature fluctuations caused by frequent switching of valve 42 connected to the rear evaporator is reduced, increasing the comfort of the rear passenger air conditioning system.
[0041] In some embodiments, the first temperature threshold is 1.5°C to 2.5°C, for example, the first temperature threshold is 1.5°C, 2°C, or 2.5°C. The second temperature threshold is -1.5°C to -0.5°C, for example, the second temperature threshold is -1.5°C, -1°C, or -0.5°C. The third temperature threshold is -2.5°C to -3.5°C, for example, the third temperature threshold is -2.5°C, -2°C, or -3.5°C. The airflow limit can be a maximum airflow limit of 2 to 4 levels, for example, a maximum airflow limit of 2, 3, or 4 levels.
[0042] like Figure 13As shown, when the difference between the rear seat interior temperature correction value and the rear seat set temperature is in different temperature ranges, SOV_State1 can be used to represent its state. When the difference between the rear passenger cabin temperature correction value and the rear passenger cabin set temperature is greater than 2℃, SOV_State1 = 0, and valve 42 connected to the rear passenger evaporator is opened; when the difference between the rear passenger cabin temperature correction value and the rear passenger cabin set temperature is less than or equal to 2℃ and greater than -1℃, SOV_State1 = 1, and valve 42 connected to the rear passenger evaporator is opened, and the airflow of the rear passenger air conditioner 40 is limited; when the difference between the rear passenger cabin temperature correction value and the rear passenger cabin set temperature is less than or equal to -1℃ and greater than -3℃, SOV_State1 = 2, and valve 42 connected to the rear passenger evaporator is closed, and the airflow of the rear passenger air conditioner 40 is limited; when the difference between the rear passenger cabin temperature correction value and the rear passenger cabin set temperature is less than or equal to -3℃, SOV_State1 = 3, and valve 42 connected to the rear passenger evaporator is closed. When the difference between the rear passenger cabin temperature correction value and the rear passenger cabin temperature setting value increases from less than or equal to -2°C to greater than -2°C and less than or equal to 1°C, the value of SOV_State1 changes from 3 to 2; when the difference increases from greater than -2°C and less than or equal to 1°C to greater than 1°C and less than or equal to 3°C, the value of SOV_State1 changes from 2 to 1; when the difference increases from greater than 1°C and less than or equal to 3°C to greater than 3°C, the value of SOV_State1 changes from 1 to 0. Of course, the temperature thresholds involved in the change of SOV_State1 value can be selected according to actual conditions, and this application is not limited to this.
[0043] In some embodiments, such as Figure 4 As shown, the in-vehicle temperature adjustment method also includes step S300.
[0044] Step S300: When the rear seat interior temperature correction value remains greater than or equal to the difference between the rear seat set temperature and the first preset error within a preset time, and the rear seat interior temperature correction value remains less than or equal to the sum of the rear seat set temperature and the first preset error, it is determined that the rear seat interior temperature correction value meets the requirements of the rear seat set temperature.
[0045] In step S300, when the front air conditioning is on, the air blown out by the front air conditioning will affect not only the temperature inside the front vehicle but also the temperature inside the rear vehicle. If the temperature correction value inside the rear vehicle meets the requirements of the rear set temperature, the set temperature of the front air conditioning will also play a role in ensuring that the temperature correction value inside the rear vehicle meets the requirements of the rear set temperature. That is, the average set temperature of the front vehicle and the set temperature of the rear vehicle simultaneously ensure that the temperature correction value inside the rear vehicle meets the requirements of the rear set temperature.
[0046] In some embodiments, the first preset error is 1°C to 3°C, for example, the first preset error is 1°C, 2°C or 3°C.
[0047] In some embodiments, the preset time is 3 to 7 minutes, for example, 3 minutes, 4 minutes, 5 minutes, 6 minutes, or 7 minutes. Of course, the temperature difference between the rear seat interior temperature correction value and the set temperature may be large for different vehicle models, and the preset time needs to be set according to the actual situation. This application is not limited to this.
[0048] In some embodiments, such as Figure 5 As shown, the in-vehicle temperature adjustment method also includes step S400.
[0049] In step S400, when the difference between the set temperature of the rear row and the average set temperature of the front row is greater than the fourth temperature threshold, the valve 42 connected to the rear row evaporator is closed; when the difference between the set temperature of the rear row and the average set temperature of the front row is less than or equal to the fourth temperature threshold and greater than the fifth temperature threshold, the valve 42 connected to the rear row evaporator is opened, and the airflow of the rear row air conditioner 40 is limited; when the difference between the set temperature of the rear row and the average set temperature of the front row is less than or equal to the fifth temperature threshold, the valve 42 connected to the rear row evaporator is opened. The fifth temperature threshold is less than the fourth temperature threshold.
[0050] In step S400, considering that the temperature inside the front seats affects the temperature inside the rear seats, the valve 42 connected to the rear evaporator is opened by comparing the average set temperature of the front seats and the set temperature of the rear seats. Since the temperature inside the rear seats changes more slowly, the average set temperature of the front seats and the set temperature of the rear seats are used as the criteria to control the opening and closing of the valve 42 connected to the rear evaporator. When the average set temperature of the front seats is low, the valve 42 connected to the rear evaporator is closed; otherwise, the temperature inside the rear seats will be lower than the set temperature. When the average set temperature of the front seats is high, the valve 42 connected to the rear evaporator is opened to continuously cool the rear seats and prevent the temperature inside the rear seats from rising. To avoid frequent opening and closing of the valve 42 connected to the rear evaporator when the average set temperature of the front seats and the set temperature of the rear seats change slightly, thus affecting the rear exhaust temperature... When the set temperature of the rear row is close to the average set temperature of the front row, the valve 42 connected to the rear row evaporator will open, and the evaporation temperature fluctuation caused by the opening and closing of the valve 42 connected to the rear row evaporator will be reduced by limiting the air volume.
[0051] In some embodiments, the fourth temperature threshold ranges from 0.5°C to 1.5°C, for example, the fourth temperature threshold is 0.5°C, 1°C, or 1.5°C. The fifth temperature threshold ranges from -2.5°C to -1.5°C, for example, the fifth temperature threshold is -2.5°C, -2°C, or -1.5°C. The airflow limit can be a maximum airflow limit of 2 to 4 levels, for example, a maximum airflow limit of 2, 3, or 4 levels.
[0052] like Figure 14 As shown, when the difference between the set temperature of the rear row and the average set temperature of the front row are in different temperature ranges, SOV_State2 can be used to represent its state. When the difference between the set temperature of the rear row and the average set temperature of the front row is greater than 1℃, SOV_State2 = 0, and the valve 42 connected to the rear row evaporator is closed; when the difference between the set temperature of the rear row and the average set temperature of the front row is less than or equal to 1℃ and greater than -2℃, SOV_State2 = 1, and the valve 42 connected to the rear row evaporator is opened, and the airflow of the rear row air conditioner 40 is limited; when the difference between the set temperature of the rear row and the average set temperature of the front row is less than or equal to -2℃, SOV_State1 = 2, and the valve 42 connected to the rear row evaporator is opened. When the difference between the set temperature of the rear seats and the average set temperature of the front seats increases from less than or equal to -1°C to greater than -1°C but less than or equal to 2°C, the value of SOV_State2 changes from 2 to 1; when the difference between the set temperature of the rear seats and the average set temperature of the front seats increases from greater than -1°C but less than or equal to 2°C to greater than 2°C, the value of SOV_State2 changes from 1 to 0. Of course, the temperature thresholds involved in the change of the value of SOV_State2 can be selected according to actual conditions, and this application is not limited to this.
[0053] In some embodiments, such as Figure 6 As shown, the in-vehicle temperature adjustment method also includes step S500.
[0054] In step S500, when the rear seat interior temperature correction value is greater than the sum of the rear seat set temperature and the second preset error, return to step S200, where the second preset error is greater than the first preset error.
[0055] In step S500, since the second preset error is greater than the first preset error, the rear seat interior temperature correction value differs significantly from the rear seat set temperature. The judgment in step S300 is not applicable to the rear seat interior temperature correction value at this time. Therefore, it is necessary to return to step S200, adjust the rear seat interior temperature in step S200, and then determine whether the rear seat interior temperature correction value is stable at the rear seat set temperature in step S300 before proceeding to the next step of adjusting and controlling the rear seat interior temperature.
[0056] In some embodiments, the value range of the second preset error is 3°C to 5°C, for example, the second preset error is 3°C, 4°C or 5°C.
[0057] In some embodiments, such as Figure 7 As shown, the in-vehicle temperature adjustment method also includes step S600.
[0058] Step S600: Determine the seasonal mode as winter mode based on the ambient temperature, and close valve 42 connected to the rear evaporator.
[0059] In steps S100 and S600, the specific method for determining the seasonal pattern based on the ambient temperature is as follows:
[0060] When the ambient temperature is greater than the sixth temperature threshold, the seasonal mode is determined to be summer mode; when the ambient temperature is less than or equal to the sixth temperature threshold but greater than the seventh temperature threshold, the seasonal mode is determined to be spring / autumn mode; when the ambient temperature is less than or equal to the seventh temperature threshold, the seasonal mode is determined to be winter mode.
[0061] In some embodiments, the sixth temperature threshold ranges from 21°C to 23°C, for example, the sixth temperature threshold is 21°C, 22°C, or 23°C. The seventh temperature threshold ranges from 4°C to 6°C, for example, the seventh temperature threshold is 4°C, 5°C, or 6°C.
[0062] like Figure 12 As shown, when the ambient temperature is greater than 22℃, the seasonal mode is summer mode; when the ambient temperature is less than or equal to 22℃ and greater than 5℃, the seasonal mode is spring / autumn mode; and when the ambient temperature is less than or equal to 5℃, the seasonal mode is winter mode. When the ambient temperature rises from less than or equal to 7℃ to greater than 7℃ and less than or equal to 25℃, the seasonal mode switches from winter mode to spring / autumn mode; and when the ambient temperature rises from greater than 7℃ and less than or equal to 25℃ to greater than 25℃, the seasonal mode switches from spring / autumn mode to summer mode. Of course, the temperature thresholds involved in switching seasonal modes can be selected according to actual conditions, and this application is not limited to this.
[0063] In some embodiments, such as Figure 8 As shown, the in-vehicle temperature adjustment method also includes step S700.
[0064] Step S700: If, within a preset time period, the rear seat interior temperature correction value is less than the difference between the rear seat set temperature and the first preset error, or the rear seat interior temperature correction value is greater than the sum of the rear seat set temperature and the first preset error, return to step S200.
[0065] In some embodiments, such as Figure 9 As shown, the in-vehicle temperature adjustment method also includes step S800.
[0066] In step S800, when the rear seat interior temperature correction value is less than or equal to the sum of the rear seat set temperature and the second preset error, return to step S400, wherein the second preset error is greater than the first preset error.
[0067] This application uses a comparison between the rear passenger cabin temperature correction value and the rear passenger cabin set temperature to determine whether the valve 42 connected to the rear passenger cabin evaporator is open, thus stabilizing the rear head temperature at the rear passenger cabin set temperature. By comparing the average front passenger cabin set temperature with the rear passenger cabin set temperature, the opening and closing of the valve 42 connected to the rear passenger cabin evaporator is controlled. This takes into account the influence of the front passenger cabin temperature on the rear passenger cabin temperature. When the front passenger cabin temperature is low, the valve 42 connected to the rear passenger cabin evaporator can be closed to avoid generating excess cooling, resulting in energy savings. When the rear passenger cabin temperature correction value is close to the rear passenger cabin set temperature, this application maintains the previous state of the valve 42 connected to the rear passenger cabin evaporator and adjusts the airflow temperature of the rear passenger air conditioning 40 by reducing the airflow volume, thereby reducing the frequency of opening and closing of the valve 42 connected to the rear passenger cabin evaporator.
[0068] like Figure 10 As shown, this application also provides an in-vehicle temperature regulation device 10, which includes a determining module 11 and a control module 12. The determining module 11 is used to receive a signal to turn on the rear air conditioning and determine the seasonal mode as spring / autumn mode or summer mode based on the ambient temperature. The control module 12 is used to open a valve 42 connected to the rear evaporator when the difference between the rear in-vehicle temperature correction value and the rear set temperature is greater than a first temperature threshold; when the difference between the rear in-vehicle temperature correction value and the rear set temperature is less than or equal to the first temperature threshold and greater than a second temperature threshold, open the valve 42 connected to the rear evaporator and limit the airflow of the rear air conditioning 40; when the difference between the rear in-vehicle temperature correction value and the rear set temperature is less than or equal to the second temperature threshold, close the valve 42 connected to the rear evaporator; wherein the second temperature threshold is less than the first temperature threshold.
[0069] This application uses a control module 12 to determine whether the valve 42 connected to the rear evaporator is open by comparing the rear seat interior temperature correction value with the rear seat set temperature. When the rear seat interior temperature correction value is close to the rear seat set temperature, the air outlet temperature of the rear air conditioner 40 is first adjusted by limiting the air outlet volume of the rear air conditioner 40, which can reduce the number of times the valve 42 connected to the rear evaporator is frequently opened and closed.
[0070] like Figure 11 As shown, this application also provides an in-vehicle temperature regulation device 20, which includes a processor 21, a memory 22, and an in-vehicle temperature regulation program stored in the memory 22 and executable by the processor 21, wherein when the in-vehicle temperature regulation program is executed by the processor 21, it implements the steps of the above-described in-vehicle temperature regulation method.
