Description

[0002] Currently, the passenger car is in a rapid development stage, and the user's requirement for the air conditioning comfort of the passenger car is also higher and higher. However, the adjustment control strategy of the existing vehicle air conditioning system usually focuses on changing the current indoor environment temperature to make the indoor environment temperature reach the set temperature, and often ignores the comfort of the driver and passenger. For example, in a low temperature environment, when the vehicle air conditioning is started, the air volume is large, and the outlet air temperature is low, and the cold air is directly blown to the body of the passenger, which is extremely uncomfortable. And the outlet air temperature of the air conditioning must go through a process from low to high, so how to improve the comfort in the low outlet air temperature stage is worth studying. In a high temperature environment, it is just the opposite, the outlet air temperature is high in the early stage of the vehicle air conditioning being started, and a large amount of hot air is blown to the body of the passenger, which is also extremely uncomfortable.

[0024] Other advantages and effects of the present application will be readily appreciated by those skilled in the art from the following description with reference to the accompanying drawings and preferred embodiments. The present application can also be put into practice in various different ways with many modifications and variations of detail, all of which do not depart from the spirit of the application. It should be understood that the preferred embodiments are only for illustrating the present application and are not intended to limit the scope of protection of the present application.

[0025] In an embodiment, referring to Figure 1 The present application provides a vehicle air conditioning control method, which comprises:

[0026] When the vehicle air conditioner is in operation, the current ambient temperature, the current air outlet temperature and the target air outlet temperature of the vehicle are obtained.

[0027] In response to the current ambient temperature of the vehicle being higher than a first preset threshold or lower than a second preset threshold, and the difference between the current air outlet temperature and the target air outlet temperature being higher than a third preset threshold, the vehicle air conditioner performs a preset response action, i.e. adjusting or maintaining the air outlet mode of the vehicle air conditioner to be window blowing.

[0028] Specifically, the current ambient temperature reflects the external environmental condition of the vehicle; the current air outlet temperature is the temperature of the air actually blown by the air conditioner; and the target air outlet temperature is the expected air outlet temperature set by the user or calculated by the system according to a preset algorithm. These three parameters are the basis for subsequent judgment.

[0029] The current ambient temperature being higher than the first preset threshold or lower than the second preset threshold means that the ambient temperature is in an extreme state. The first preset threshold can be a relatively high temperature value, and when the ambient temperature is higher than this value, it means that the external environment is very hot; the second preset threshold can be a relatively low temperature value, and when the ambient temperature is lower than this value, it means that the external environment is very cold.

[0030] Temperature difference judgment: the difference between the current air outlet temperature and the target air outlet temperature being higher than the third preset threshold means that there is a large deviation between the actual air outlet temperature and the expected air outlet temperature of the air conditioner, which can be caused by excessive influence of the ambient temperature.

[0031] If the current ambient temperature is higher than the first preset threshold, i.e. the external environment is high temperature, the calculation formula of the difference between the current air outlet temperature and the target air outlet temperature is: difference = current air outlet temperature - target air outlet temperature.

[0032] If the current ambient temperature is lower than the second preset threshold, i.e. the external environment is low temperature, the calculation formula of the difference between the current air outlet temperature and the target air outlet temperature is: difference = target air outlet temperature - current air outlet temperature.

[0033] It should be noted that the "adjusting or maintaining" means that if the current air outlet mode of the vehicle air conditioner is not the window-blowing mode, it is adjusted to the window-blowing mode; if the current vehicle air conditioner is already in the window-blowing mode, the mode remains unchanged.

[0034] The application adjusts or maintains the air outlet mode of the vehicle air conditioner to the window-blowing mode when the current ambient temperature of the vehicle is higher than the first preset threshold or lower than the second preset threshold, and the difference between the current air outlet temperature and the target air outlet temperature is higher than the third preset threshold. In this way, the discomfort caused by the direct blowing of cold air on the body of the driver and passenger at the initial stage of starting the air conditioner in a low-temperature environment and the direct blowing of hot air on the body at the initial stage of starting the air conditioner in a high-temperature environment is effectively avoided.

[0035] In this embodiment, the first preset threshold is 28℃, the second preset threshold is 5℃, and the third preset threshold is 5℃.

[0036] As a preferred embodiment of the application, the vehicle air conditioner control method further comprises: in response to the current ambient temperature of the vehicle being lower than the second preset threshold and the difference between the current air outlet temperature and the target air outlet temperature being higher than the third preset threshold, limiting the air blower of the vehicle air conditioner to a low-air-volume working mode.

[0037] Specifically, as shown in Figure 2 The application provides a vehicle air conditioner control method, which comprises:

[0038] When the vehicle air conditioner is in a working state, the current ambient temperature, the current air outlet temperature and the target air outlet temperature of the vehicle are obtained.

[0039] It is judged whether the current ambient temperature of the vehicle is lower than the second preset threshold. If not, the vehicle air conditioner is maintained in a preset working mode, i.e., the working mode of the vehicle air conditioner remains unchanged. If yes, the next step is performed.

[0040] It is judged whether the difference between the current air outlet temperature and the target air outlet temperature is higher than the third preset threshold. If not, the vehicle air conditioner is maintained in a preset working mode, i.e., the working mode of the vehicle air conditioner remains unchanged. If yes, the vehicle air conditioner performs a preset response action, i.e., the air outlet mode of the vehicle air conditioner is adjusted or maintained to the window-blowing mode, and the air blower of the vehicle air conditioner is limited to a low-air-volume working mode.

[0041] In the initial stage of starting the air conditioner in a low-temperature environment, the air conditioner of the application not only avoids direct blowing of cold air, but also more quickly increases the outlet air temperature by reducing the air volume of the air blower, thereby improving the user's body temperature and effectively avoiding the problem of blowing cold air in a low-temperature environment. For example, in winter in the north, after the vehicle is started, this control mode can prevent the people in the vehicle from feeling colder due to the rapid circulation of a large amount of cold air during the process of waiting for the air conditioner to heat.

[0042] As a preferred embodiment of the application, the vehicle air conditioner control method further comprises: when the vehicle air conditioner is in a working state, further acquiring a current passenger compartment temperature and a current evaporator temperature of the vehicle, and in response to the current environment temperature of the vehicle being higher than a first preset threshold, the difference between the current outlet air temperature and the target outlet air temperature being higher than a third preset threshold, and the current passenger compartment temperature of the vehicle being higher than a fourth preset threshold or the current evaporator temperature being higher than a fifth preset threshold, the vehicle air conditioner performs a preset response action to adjust or maintain the vehicle air conditioner outlet air mode as window blowing.

[0043] Specifically, referring to Figure 3 The application provides a vehicle air conditioner control method, which comprises:

[0044] When the vehicle air conditioner is in a working state, the current environment temperature, the current outlet air temperature, the target outlet air temperature, the current passenger compartment temperature and the current evaporator temperature of the vehicle are acquired.

[0045] It is judged whether the current environment temperature of the vehicle is higher than a first preset threshold, and if not, the vehicle air conditioner is maintained in a preset working mode, i.e., the working mode of the vehicle air conditioner remains unchanged. If yes, the next step is performed.

[0046] It is judged whether the difference between the current outlet air temperature and the target outlet air temperature is higher than a third preset threshold, and if not, the vehicle air conditioner is maintained in a preset working mode, i.e., the working mode of the vehicle air conditioner remains unchanged. If yes, the next step is performed.

[0047] It is judged whether the current passenger compartment temperature is higher than a fourth preset threshold or the current evaporator temperature is higher than a fifth preset threshold. If not, the vehicle air conditioner is maintained in a preset working mode, i.e., the working mode of the vehicle air conditioner remains unchanged. If yes, i.e., the current passenger compartment temperature is higher than the fourth preset threshold or the current evaporator temperature is higher than the fifth preset threshold, the vehicle air conditioner performs a preset response action, i.e., adjusts or maintains the vehicle air conditioner outlet air mode as window blowing.

[0048] In a high-temperature environment, i.e. the current ambient temperature of the vehicle is higher than the first preset threshold, adjusting the air outlet mode only according to the difference between the ambient temperature and the air outlet temperature may not be comprehensive enough. The newly added conditions of the passenger compartment temperature and the evaporator temperature can more accurately judge the actual heat condition in the vehicle. For example, after the vehicle is exposed to the sun in summer, even if the ambient temperature is high, if the passenger compartment temperature or the evaporator temperature does not reach the corresponding threshold, it may not be necessary to immediately adjust the air outlet mode to blow the window; when these conditions are met, it means that the heat load in the vehicle is large, and at this time, adjusting the air outlet mode to blow the window can avoid blowing hot air directly at the driver and passenger, and at the same time help to quickly reduce the temperature in the vehicle.

[0049] The present application can more accurately adapt to different working conditions in a high-temperature environment by introducing more temperature parameters and more complex condition judgments, further improving the comfort of the driver and passenger. It avoids adjusting the air outlet mode to blow the window in unnecessary cases, and ensures that measures can be taken in time when it is really needed, improving the driving experience.

[0050] In this embodiment, the fourth preset threshold is 30℃, and the fifth preset threshold is 25℃.

[0051] As a preferred embodiment of the present application, the vehicle air conditioner control method of the present application further comprises: Figure 4 As shown in the figure, after the vehicle air conditioner performs the preset response action, the current air outlet temperature and the target air outlet temperature of the vehicle are continuously obtained, and in response to the difference between the current air outlet temperature and the target air outlet temperature being not higher than the sixth preset threshold, the vehicle air conditioner stops performing the preset response action and returns to the preset working mode.

[0052] In this embodiment, the sixth preset threshold is 2℃.

[0053] After the vehicle air conditioner performs the preset response action (such as adjusting or maintaining the blow window mode, limiting the air volume of the air blower, etc.), the vehicle air conditioner control method of the present application introduces a continuous feedback mechanism, i.e. by continuously obtaining the current air outlet temperature and the target air outlet temperature, the system can real-time understand the difference between the actual air outlet of the air conditioner and the expected target. If the difference between the current air outlet temperature and the target air outlet temperature is not higher than the sixth preset threshold, it means that the air outlet of the air conditioner has approached or reached the expected temperature state. At this time, the system determines to stop performing the preset response action, so that the vehicle air conditioner returns to the preset working mode, realizing the closed-loop control of dynamically adjusting the working state of the air conditioner according to the actual air outlet effect.

[0054] At the initial stage of starting the air conditioner in an extreme temperature environment, the preset response action can avoid the uncomfortable wind directly blowing on the body of the driver and passenger. When the temperature of the air out of the air conditioner approaches the target temperature, the preset response action is stopped in time and the preset working mode is restored, which can ensure the comfort of the driver and passenger and avoid unnecessary energy consumption. For example, in a low temperature environment, when the air blown by the air conditioner gradually becomes hot and approaches the target temperature, the air volume of the air blower is no longer limited or the air out mode is changed, so that the air conditioner can operate in a more efficient way to quickly adjust the temperature in the vehicle.

[0055] During the driving of the vehicle, the environmental temperature, the thermal load of the passenger compartment and other factors can change continuously. This dynamic adjustment mechanism enables the air conditioning system to respond in time according to the actual air out condition and adapt to different working condition changes, so as to always provide a relatively stable and comfortable environment for the driver and passenger.

[0056] In this way, the intelligence and humanization of the vehicle air conditioning control are further improved. The system can automatically sense the change of the temperature of the air out and flexibly adjust the working mode according to the actual condition without manual intervention of the driver and passenger, which improves the convenience and comfort of use. Energy waste caused by the continuous execution of the preset response action when the temperature of the air out meets the requirements is avoided. By restoring the preset working mode in time, the energy utilization efficiency of the air conditioning system is optimized, which helps to reduce the energy consumption of the vehicle.

[0057] As a preferred embodiment of the present application, the vehicle air conditioning control method of the present application further comprises: Figure 5 As shown in FIG. 6, after the vehicle air conditioner executes the preset response action, the length of time after the execution of the preset response action is obtained, and when the length of time after the execution of the preset response action is greater than a preset time threshold, the vehicle air conditioner stops executing the preset response action and restores to the preset working mode.

[0058] In this embodiment, the preset time threshold is 2 minutes.

[0059] At the initial stage of starting the air conditioner in a high temperature or low temperature environment, the preset response action can ensure the comfort of the driver and passenger, but long-time execution can affect the efficiency of the air conditioner. Through time threshold control, even if the temperature difference does not reach the ideal state, the normal mode is restored after a certain period of time, which ensures the comfort in the early stage and improves the running efficiency of the air conditioner in the later stage, achieving the balance between comfort and efficiency.

[0060] The time threshold control provides additional stability guarantee for the system, reduces the possibility of abnormal operation of the system due to problems in single temperature judgment, and improves the reliability of the entire air conditioning control system. In various complex working conditions, the air conditioning system can operate more reasonably, so that the driver and passenger can enjoy a relatively stable and comfortable environment in the vehicle in any case, further optimizing the user experience.

[0061] As a preferred embodiment of the present application, the first preset threshold, the second preset threshold and the third preset threshold are determined by calibration test.

[0062] Calibration test is a method of obtaining accurate parameters through actual test. In the vehicle air conditioning control scene, the performance of air conditioning systems of different vehicle models, the structure of the vehicle interior space, the heat insulation performance and the performance in the face of different climate conditions are different. By determining the first, second and third preset thresholds through calibration test, the best temperature limit for triggering the corresponding air conditioning control strategy can be accurately found according to the actual characteristics and use environment of the vehicle. For example, the air conditioning refrigeration and heating efficiency of a certain vehicle model is high, the vehicle interior space is small and the heat insulation performance is good, so the corresponding preset threshold may be different from other vehicle models, and the calibration test can accurately set the specific situation of the vehicle.

[0063] During the calibration test, various influencing factors can be considered comprehensively, such as the climate conditions of the region where the vehicle is located, the temperature range of different seasons, the sensitivity of the people in the vehicle to temperature changes, and the fluctuation of the environment temperature during vehicle driving, etc. The preset threshold determined in this way is not a simple theoretical value, but a result fully combining various complex factors in the actual use scene, so that the vehicle air conditioning control strategy is more scientific and practical.

[0064] Accurate preset threshold can make the vehicle air conditioner more accurately trigger the corresponding control action under different environmental conditions, avoid discomfort caused by unreasonable threshold setting, and significantly improve the comfort of the driver and passengers. At the same time, reasonable threshold setting helps the air conditioning system to run more efficiently under different working conditions, improves the overall performance of the air conditioner, and prolongs its service life.

[0065] In another embodiment, the present application also provides a vehicle air conditioning control system, comprising an acquisition module, a judgment module and a response module.

[0066] Further, when the vehicle air conditioner is in the working state, the acquisition module is further configured to acquire a current passenger cabin temperature of the vehicle and an evaporator temperature; and in response to the current ambient temperature of the vehicle being higher than a first preset threshold, a difference between the current air outlet temperature and the target air outlet temperature being higher than a third preset threshold, and the current passenger cabin temperature of the vehicle being higher than a fourth preset threshold or the evaporator temperature being higher than a fifth preset threshold, the vehicle air conditioner performs a preset response action, and adjusts or maintains the air outlet mode of the vehicle air conditioner as blowing the window.

[0067] Further, the system further comprises a monitoring module; the monitoring module is configured to continue to acquire the current air outlet temperature and the target air outlet temperature of the vehicle after the vehicle air conditioner performs the preset response action, and in response to the difference between the current air outlet temperature and the target air outlet temperature being not higher than the third preset threshold, the vehicle air conditioner stops performing the preset response action and returns to the preset working mode; or the monitoring module is configured to acquire a time length after the vehicle air conditioner performs the preset response action after the vehicle air conditioner performs the preset response action, and in response to the time length after the vehicle air conditioner performs the preset response action being greater than a preset time threshold, the vehicle air conditioner stops performing the preset response action and returns to the preset working mode.

[0068] In another embodiment, the present application further provides a vehicle comprising the vehicle air conditioner control system according to any one of the above embodiments.
