Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of vehicle air conditioning, and in particular to a vehicle air conditioning control method, system and vehicle. Background Art
[0002] Passenger cars are currently in a stage of rapid development, and users have higher and higher requirements for the air conditioning comfort of passenger cars. However, the regulation and control strategies of existing vehicle air conditioning systems usually focus on changing the current in-car ambient temperature so that the in-car ambient temperature reaches the set temperature, but often ignore the comfort of the driver and passengers. For example, in a low-temperature environment, when the vehicle air conditioner is started, the air volume is large, but the outlet air temperature is very low, and the cold air blows directly onto the body of the passengers, which is extremely uncomfortable. When the air conditioner is turned on, the outlet air temperature must go through a process from low to high, so how to improve comfort at 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 conditioner being turned on. At this time, a large amount of hot air blows onto the body of the passengers, which is also extremely uncomfortable. Summary of the invention

[0007] Furthermore, the method also includes: after the vehicle air conditioner executes a preset response action, continuing to obtain the vehicle's current air outlet temperature and target air outlet temperature, in response to the difference between the current air outlet temperature and the target air outlet temperature being no higher than a third preset threshold, the vehicle air conditioner stops executing the preset response action and returns to a preset working mode.

[0011] Furthermore, when the vehicle air conditioner is in working state, the acquisition module is also used to obtain the current passenger compartment temperature and evaporator temperature of the vehicle; in response to the current ambient temperature of the vehicle being higher than the first preset threshold, the difference between the current air outlet temperature and the target air outlet temperature being higher than the third preset threshold, and the current passenger compartment temperature of the vehicle being higher than the fourth preset threshold or the evaporator temperature being higher than the fifth preset threshold, the vehicle air conditioner executes a preset response action to adjust or maintain the vehicle air conditioner air outlet mode to window blowing.

DETAILED DESCRIPTION
[0017] The following will describe the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.
[0018] In one embodiment, see Figure 1 As shown, the present invention provides a vehicle air conditioning control method, which includes: When the vehicle air conditioner is in operation, the current ambient temperature, current air outlet temperature and target air outlet temperature of the vehicle are obtained.
[0019] In response to the vehicle's current ambient temperature 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 vehicle air conditioner air outlet mode to window blowing.
[0020] Specifically, the current ambient temperature reflects the environmental conditions outside the vehicle; the current outlet air temperature is the temperature of the air actually blown out by the air conditioner; and the target outlet air temperature is the expected outlet air temperature set by the user or calculated by the system based on a preset algorithm. These three parameters are the basis for subsequent judgments.
[0021] If the current ambient temperature is higher than the first preset threshold or lower than the second preset threshold, it means that the ambient temperature is in a relatively extreme state. The first preset threshold may be a relatively high temperature value. When the ambient temperature is higher than this value, it means that the external environment is very hot; the second preset threshold may be a relatively low temperature value. When the ambient temperature is lower than this value, it means that the external environment is very cold.
[0022] Temperature difference judgment: The difference between the current air outlet temperature and the target air outlet temperature is higher than the third preset threshold, indicating that there is a large deviation between the actual air outlet temperature of the air conditioner and the expected air outlet temperature, which may be caused by the excessive influence of the ambient temperature.
[0023] If the current ambient temperature is higher than the first preset threshold, that is, the external environment is high temperature, the difference between the current outlet air temperature and the target outlet air temperature is calculated as follows: difference = current outlet air temperature - target outlet air temperature.
[0024] If the current ambient temperature is lower than the second preset threshold, that is, the external environment is low temperature, the difference between the current air outlet temperature and the target air outlet temperature is calculated as follows: difference = target air outlet temperature - current air outlet temperature.
[0025] It should be noted that "adjust or maintain" means that if the current air outlet mode of the vehicle air conditioner is not the window blowing mode, it will be adjusted to the window blowing mode; if the vehicle air conditioner is currently in the window blowing mode, the mode will remain unchanged.
[0026] The present invention obtains the current ambient temperature, current air outlet temperature and target air outlet temperature of the vehicle when the vehicle air conditioner is in working state, and when the current ambient temperature of the vehicle obtained 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, the vehicle air conditioner performs a preset response action, that is, adjusts or maintains the vehicle air conditioner outlet mode to window blowing. This arrangement effectively avoids the discomfort caused by cold air directly blowing on the body of the driver and passengers when the air conditioner is turned on in a low temperature environment at the beginning, and hot air directly blowing on the body when the air conditioner is turned on in a high temperature environment at the beginning.
[0027] In this embodiment, the first preset threshold is 28°C, the second preset threshold is 5°C, and the third preset threshold is 5°C.
[0028] As a preferred embodiment of the present invention, the vehicle air-conditioning control method of the present invention also includes: in response to the current ambient temperature of the vehicle being 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, limiting the blower of the vehicle air-conditioning to a low air volume operating mode.
[0029] Specifically, see Figure 2 As shown, the present invention provides a vehicle air conditioning control method, which includes: When the vehicle air conditioner is in operation, the current ambient temperature, current air outlet temperature and target air outlet temperature of the vehicle are obtained.
[0030] It is determined whether the current ambient temperature of the vehicle is lower than the second preset threshold value. If not, the vehicle air conditioner is maintained in the preset working mode, that is, the vehicle air conditioner working mode remains unchanged. If yes, the next step is executed.
[0031] It is determined whether the difference between the current air outlet temperature and the target air outlet temperature is higher than a third preset threshold value. If not, the vehicle air conditioner is maintained in a preset working mode, that is, the vehicle air conditioner working mode remains unchanged. If yes, the vehicle air conditioner performs a preset response action, that is, the vehicle air conditioner air outlet mode is adjusted or maintained to window blowing, and the blower of the vehicle air conditioner is limited to a low air volume working mode.
[0032] In the early stage of turning on the air conditioner in a low-temperature environment, the present invention not only avoids direct blowing of cold air, but also increases the outlet temperature more quickly by reducing the air volume of the blower, thereby increasing the user's perceived temperature, effectively avoiding the problem of blowing cold air in a low-temperature environment. For example, in the winter in the north, after the vehicle is started, this control method can prevent the occupants from feeling even colder due to the rapid circulation of a large amount of cold air while waiting for the air conditioner to heat up.
[0033] As a preferred embodiment of the present invention, the vehicle air-conditioning control method of the present invention also includes: when the vehicle air-conditioning is in working state, the current passenger compartment temperature and the current evaporator temperature of the vehicle are also obtained, in response to the current ambient temperature of the vehicle being higher than the first preset threshold, the difference between the current air outlet temperature and the target air outlet temperature being higher than the third preset threshold, and the current passenger compartment temperature of the vehicle being higher than the fourth preset threshold or the current evaporator temperature being higher than the fifth preset threshold, the vehicle air-conditioning executes a preset response action to adjust or maintain the vehicle air-conditioning air outlet mode to window blowing.
[0034] Specifically, see Figure 3 As shown, the present invention provides a vehicle air conditioning control method, which includes: When the vehicle air conditioner is in operation, the vehicle's current ambient temperature, current air outlet temperature, target air outlet temperature, current passenger compartment temperature, and current evaporator temperature are obtained.
[0035] Determine whether the current ambient temperature of the vehicle is higher than a first preset threshold value, if not, maintain the vehicle air conditioner in a preset working mode, that is, the vehicle air conditioner working mode remains unchanged. If yes, execute the next step.
[0036] It is determined whether the difference between the current outlet air temperature and the target outlet air temperature is higher than a third preset threshold value, if not, the vehicle air conditioner is maintained in a preset working mode, that is, the vehicle air conditioner working mode remains unchanged. If yes, the next step is executed.
[0037] It is determined whether the current passenger compartment temperature is higher than a fourth preset threshold or whether the current evaporator temperature is higher than a fifth preset threshold. If not, the vehicle air conditioner is maintained in a preset working mode, that is, the vehicle air conditioner working mode remains unchanged. If yes, that is, 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, that is, the vehicle air conditioner air outlet mode is adjusted or maintained to window blowing.
[0038] In a high temperature environment, that is, the current ambient temperature of the vehicle is higher than the first preset threshold, adjusting the air outlet mode based solely on the difference between the ambient temperature and the air outlet temperature may not be comprehensive enough. The newly added passenger compartment temperature and evaporator temperature conditions can more accurately judge the actual thermal conditions in the car. For example, in a vehicle that has been exposed to the sun in summer, even if the ambient temperature is high, if the passenger compartment temperature or the evaporator temperature has not reached the corresponding threshold, it may not be necessary to immediately adjust the air outlet mode to window blowing; and when all these conditions are met, it means that the heat load in the car is large. At this time, adjusting the air outlet mode to window blowing can avoid hot air blowing directly on the driver and passengers, and at the same time help to quickly reduce the temperature in the car.
[0039] The present invention can more accurately adapt to different working conditions in high temperature environments by introducing more temperature parameters and more complex condition judgments, further improving the comfort of drivers and passengers. It avoids adjusting the air outlet mode to window blowing when it is unnecessary, and ensures that measures can be taken in time when it is really needed to improve the driving experience.
[0040] In this embodiment, the fourth preset threshold is 30°C, and the fifth preset threshold is 25°C.
[0041] As a preferred embodiment of the present invention, the vehicle air conditioning control method of the present invention further includes: Figure 4 As shown, after the vehicle air conditioner executes the preset response action, it continues to obtain the vehicle's current air outlet temperature and target air outlet temperature. In response to the difference between the current air outlet temperature and the target air outlet temperature being no higher than the sixth preset threshold, the vehicle air conditioner stops executing the preset response action and returns to the preset working mode.
[0042] In this embodiment, the sixth preset threshold is 2°C.
[0043] After the vehicle air conditioner executes a preset response action (such as adjusting or maintaining the window blowing mode, limiting the blower air volume, etc.), the vehicle air conditioner control method of the present invention introduces a continuous feedback mechanism, that is, by continuing to obtain the current air outlet temperature and the target air outlet temperature, the system can understand in real time the gap 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 desired temperature state. At this time, the system determines that it can stop executing the preset response action, so that the vehicle air conditioner can be restored to the preset working mode, realizing closed-loop control of dynamically adjusting the working state of the air conditioner according to the actual air outlet effect.
[0044] When the air conditioner is turned on in the early stage of extreme temperature environment, the preset response action can prevent unsuitable wind from blowing directly on the body of the driver and passengers. When the air outlet temperature approaches the target temperature, the preset response action is stopped in time and the preset working mode is restored, which can not only ensure the comfort of the driver and passengers, but also avoid unnecessary energy consumption. For example, in a low temperature environment, when the air blown by the air conditioner gradually becomes hotter and approaches the target temperature, the blower air volume is no longer restricted or the air outlet mode is changed, allowing the air conditioner to operate in a more efficient way and quickly adjust the temperature in the car.
[0045] During the driving process, factors such as ambient temperature and passenger compartment heat load may change continuously. This dynamic adjustment mechanism enables the air conditioning system to respond in time according to the actual air output conditions, adapt to different working conditions, and always provide a relatively stable and comfortable environment for the driver and passengers.
[0046] This setting further improves the intelligence and humanization of vehicle air conditioning control. The system can automatically sense changes in the outlet air temperature and flexibly adjust the working mode according to the actual situation without manual intervention by the driver and passengers, which improves the convenience and comfort of use. It avoids the energy waste caused by continuing to execute the preset response action when the outlet air temperature has met the requirements. By restoring the preset working mode in a timely manner, the energy utilization efficiency of the air conditioning system is optimized, which helps to reduce the energy consumption of the vehicle.
[0047] As a preferred embodiment of the present invention, the vehicle air conditioning control method of the present invention further includes: Figure 5 As shown, after the vehicle air conditioner executes a preset response action, the length of time after the vehicle air conditioner executes the preset response action is obtained. In response to the length of time after the vehicle air conditioner executes the preset response action being greater than a preset time threshold, the vehicle air conditioner stops executing the preset response action and returns to the preset working mode.
[0048] In this embodiment, the preset time threshold is 2 minutes.
[0049] When the air conditioner is turned on in high or low temperature environments, the preset response action can ensure the comfort of the driver and passengers, but long-term execution may affect the efficiency of the air conditioner. Through time threshold control, even if the temperature difference does not reach the ideal state, it will return to normal mode after a certain period of time, which not only ensures comfort in the early stage, but also improves the operating efficiency of the air conditioner in the later stage, achieving a balance between comfort and efficiency.
[0050] Time threshold control provides additional stability guarantee for the system, reduces the possibility of abnormal operation of the system due to a single temperature judgment problem, and improves the reliability of the entire air conditioning control system. In addition, it can make the air conditioning system operate more reasonably under various complex working conditions, allowing drivers and passengers to enjoy a relatively stable and comfortable in-car environment under any circumstances, further optimizing the user experience.
[0051] As a preferred implementation manner of the present invention, the first preset threshold, the second preset threshold and the third preset threshold are determined through calibration tests.
[0052] Calibration testing is a method of obtaining accurate parameters through actual testing. In the vehicle air conditioning control scenario, the air conditioning system performance, interior space structure, thermal insulation performance, and performance in different climatic conditions of different models vary. By determining the first, second, and third preset thresholds through calibration tests, the optimal temperature limits for triggering the corresponding air conditioning control strategy can be accurately found according to the actual characteristics of the vehicle and the use environment. For example, a certain car has a high air conditioning cooling and heating efficiency, a small interior space and good thermal insulation performance, then its corresponding preset threshold may be different from other models. Through calibration tests, it can be accurately set according to the specific situation of the vehicle.
[0053] During the calibration test, a variety of influencing factors can be comprehensively considered, such as the climate conditions of the vehicle's location, the temperature range in different seasons, the sensitivity of the occupants to temperature changes, and the fluctuation of the ambient temperature during vehicle driving. The preset threshold value determined in this way is not a simple theoretical value, but a result that fully combines various complex factors in actual use scenarios, making the vehicle air conditioning control strategy more scientific and practical.
[0054] Accurate preset thresholds can enable the vehicle air conditioner to trigger corresponding control actions more accurately under different environmental conditions, avoiding discomfort caused by unreasonable threshold settings, thereby significantly improving the comfort of drivers and passengers. At the same time, reasonable threshold settings help the air conditioning system operate more efficiently under different working conditions, improve the overall performance of the air conditioner, and extend its service life.
[0055] In another embodiment, the present invention further provides a vehicle air conditioning control system, including an acquisition module, a judgment module and a response module. When the vehicle air conditioning is in working state, the acquisition module is used to acquire the current ambient temperature, current air outlet temperature and target air outlet temperature of the vehicle; the judgment module is used to judge whether the current ambient temperature of the vehicle is higher than the first preset threshold or lower than the second preset threshold, and is used to judge whether the difference between the current air outlet temperature and the target air outlet temperature is higher than the third preset threshold; the response module is used to control the vehicle air conditioning to perform a preset response action, that is, to adjust or maintain the vehicle air conditioning outlet mode to window blowing 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.
[0056] Furthermore, when the vehicle air conditioner is in working state, the acquisition module is also used to obtain the current passenger compartment temperature and evaporator temperature of the vehicle; in response to the current ambient temperature of the vehicle being higher than the first preset threshold, the difference between the current air outlet temperature and the target air outlet temperature being higher than the third preset threshold, and the current passenger compartment temperature of the vehicle being higher than the fourth preset threshold or the evaporator temperature being higher than the fifth preset threshold, the vehicle air conditioner executes a preset response action to adjust or maintain the vehicle air conditioner outlet mode to window blowing.
[0057] Furthermore, the system also includes a monitoring module; the monitoring module is used to continue to obtain the current air outlet temperature and the target air outlet temperature of the vehicle after the vehicle air conditioner executes 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 a third preset threshold, the vehicle air conditioner stops executing the preset response action and returns to a preset working mode; or, the monitoring module is used to obtain the length of time after the vehicle air conditioner executes the preset response action after the vehicle air conditioner executes the preset response action, and in response to the length of time after the vehicle air conditioner executes the preset response action being greater than a preset time threshold, the vehicle air conditioner stops executing the preset response action and returns to the preset working mode.

[0059] The above embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Any equivalent substitution or change made by a person skilled in the art based on the present invention is within the protection scope of the present invention.
