[0053] In the following description, specific details such as specific system structures and techniques are provided for purposes of illustration rather than limitation to facilitate a thorough understanding of the embodiments of the present application. However, it will be apparent to those skilled in the art that the present application may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid obscuring the description of the present application with unnecessary detail.

[0054] In order to make the purpose, technical solutions and advantages of this application clearer, specific embodiments will be described below with reference to the accompanying drawings.

[0055] As described in related art, existing vehicle air conditioning control schemes generally operate at a set temperature after the vehicle air conditioner is turned on. Once the cabin temperature reaches the set temperature, the air conditioner stops cooling (heating). However, this type of control is too mechanical and generally results in a poor user experience. Furthermore, existing vehicle air conditioning control schemes also suffer from high energy consumption.

[0056] In order to solve the problems of the prior art, the embodiments of the present application provide a method, device, electronic device and vehicle for controlling a vehicle air conditioner. The control method of the vehicle air conditioner provided by the embodiments of the present application is first introduced below.

[0057] The executor of the vehicle air conditioner control method may be a vehicle air conditioner control device, such as a vehicle control unit (VCU), an electronic control unit (ECU), or any electronic device capable of executing related processing of the vehicle air conditioner control method. The embodiments of the present application do not specifically limit them.

[0058] See also Figure 1 , which shows a flow chart of the implementation of the vehicle air conditioner control method provided by the embodiment of the present application, which is detailed as follows:

[0059] Step 110: Monitor the temperature parameters of the vehicle while the vehicle air conditioner is operating.

[0060] In some embodiments, the temperature parameter may be a temperature representing the interior or exterior of the vehicle, such as the cabin interior temperature or the cabin exterior temperature. The vehicle may be any type of vehicle, such as a gasoline vehicle, a diesel vehicle, or a new energy vehicle such as an EV (Electric Vehicle), an HEV (Hybrid Electric Vehicle), or a PHEV (Plug-in Hybrid Electric Vehicle).

[0061] Step 120: When the absolute value of the temperature difference between the cabin exterior temperature and the vehicle's preset temperature is greater than or equal to a preset temperature threshold, if the cabin exterior temperature is lower than the user-preset temperature, the air-conditioning temperature of the vehicle's air conditioner is set to the difference between the user-preset temperature and the preset value; if the cabin exterior temperature is higher than the user-preset temperature, the air-conditioning temperature is set to the sum of the user-preset temperature and the preset value.

[0062] In some embodiments, the user-preset temperature can be a commonly used air conditioning temperature specifically set by the user or a temporarily set air conditioning temperature. Specifically, for commonly used air conditioning temperatures, the user can select the corresponding setting program on the human-machine interface of the vehicle multimedia host screen and then set the commonly used air conditioning temperature, such as 22°C. This eliminates the need for the user to repeatedly set the air conditioning temperature of the vehicle air conditioner when using it. Temporarily set air conditioning temperatures can be operated by the vehicle owner or a passenger. It is worth mentioning that if the user temporarily sets the air conditioning temperature when a commonly used air conditioning temperature already exists, the temporarily set air conditioning temperature will be used as the user-preset temperature.

[0063] In some embodiments, the air conditioning temperature is a target temperature set for cooling or heating the vehicle air conditioner. After reaching this target temperature, the vehicle air conditioner can enter sleep, standby or low-power operation according to a built-in control program.

[0064] It's important to note that in winter and summer, when the temperature difference between inside and outside the vehicle is significant, if the vehicle's air conditioning is mechanically controlled according to the user's preset temperature, it can easily cause users to catch a cold when getting in and out of the vehicle. Furthermore, in winter and summer, when the temperature difference between inside and outside the vehicle is significant, users often set unreasonable air conditioning temperatures, further increasing the risk of catching a cold. To address this, the vehicle's air conditioning temperature can be adjusted based on the external cabin temperature.

[0065] Specifically, if the absolute value of the difference between the outside cabin temperature and the user-set temperature is less than a preset temperature threshold, meaning the vehicle's internal and external temperature difference is small (e.g., the preset temperature threshold is 10°C or 15°C), the risk of the user catching a cold when getting in and out of the vehicle is low, and the air conditioning temperature can be set directly to the user-set temperature. If the absolute value of the difference between the outside cabin temperature and the user-set temperature is greater than or equal to the preset temperature threshold, meaning the vehicle's internal and external temperature difference is large, the air conditioning temperature can be set based on the relative height between the two. If the outside cabin temperature is lower than the user-set temperature, the air conditioning temperature can be adjusted to the difference between the user-set temperature and the preset value. If the outside cabin temperature is higher than the user-set temperature, the air conditioning temperature can be adjusted to the sum of the user-set temperature and the preset value.

[0066] Taking the preset temperature threshold of 11°C, the preset value of 5°C, and the user-preset temperature of 22°C as an example, assuming that the external cabin temperature is 35°C, the external cabin temperature is higher than the user-preset temperature, and the absolute value of the temperature difference between the two, 13°C, is greater than the preset temperature threshold, then the air conditioning temperature is 22°C + 5°C = 27°C.

[0067] In this way, through the relationship between the external cabin temperature and the user's preset temperature, the risk of catching a cold caused by the temperature difference between the inside and outside of the car when the user gets on and off the car can be predicted, and then the air-conditioning temperature can be adjusted in advance to reduce the temperature difference between the inside and outside of the car, thereby reducing the risk of catching a cold when the user gets on and off the car, greatly improving the user experience.

[0068] It is worth mentioning that in addition to the above-mentioned process of automatically adjusting the air-conditioning temperature to reduce the risk of colds, the embodiment of the present invention can also control the air outlet direction or air outlet mode of the vehicle air-conditioning according to other temperature parameters of the vehicle, such as the temperature outside the cabin, so as to further improve the user experience of the vehicle air-conditioning and reduce the energy consumption of the vehicle air-conditioning.

[0069] In some embodiments, if the vehicle's interior temperature differs significantly from a user-set temperature, the air outlet of the vehicle air conditioner can be adjusted toward the seat to quickly reach the user's preset temperature, thereby enhancing the user's sensory experience. The air outlet orientation refers to the direction in which the air from the vehicle air conditioner is output. For example, the air outlet in front of the passenger seat can be oriented toward the seat, i.e., the passenger seat, or toward a non-seat direction, such as the window to the right of the passenger seat or the roof.

[0070] Specifically, if the absolute value of the difference between the cabin temperature and the user-set temperature is greater than or equal to a preset temperature threshold, the air outlet of the vehicle air conditioner is adjusted to face the seat. If the absolute value of the difference between the cabin temperature and the user-set temperature is less than the preset temperature threshold, the air outlet of the vehicle air conditioner is periodically adjusted between facing the seat and facing away from the seat.

[0071] It's worth noting that the seat direction can be either the face or foot direction for the user, or a range of directions between the face and foot directions. For this range, the air outlet direction of the vehicle air conditioner can be adjusted in a sweeping manner within the range, meaning the air outlet direction continuously changes within the range, rather than being fixed to a single direction.

[0072] In some embodiments, when the external temperature of the vehicle is close to the user's preset temperature, such as when the vehicle drives from a low-temperature place to a high-temperature place, such as a garage, the air outlet mode of the vehicle air conditioner can be adjusted to use natural wind for heating or cooling to reduce the energy consumption generated by the operation of the air-conditioning compressor.

[0073] The air outlet mode refers to the internal circulation air outlet mode or the external circulation air outlet mode. The internal circulation air outlet mode means that the air output by the car air conditioner comes from the inside of the vehicle, and the external circulation air outlet mode means that part or all of the air output by the car air conditioner comes from the outside of the vehicle.

[0074] Specifically, if the absolute value of the temperature difference between the cabin exterior temperature and the user-set temperature is less than a preset temperature threshold, the vehicle air conditioner's air flow mode is adjusted to external circulation. If the absolute value of the temperature difference between the cabin exterior temperature and the user-set temperature is greater than or equal to the preset temperature threshold, the vehicle air conditioner's air flow mode is adjusted to internal circulation.

[0075] In some embodiments, when the vehicle air conditioner is in the internal circulation air outlet mode for a long time, the concentration of harmful gases such as carbon dioxide in the car will increase. At this time, the vehicle air conditioner can be controlled to switch to the external circulation air outlet mode to purify the air environment in the car, thereby improving the user experience.

[0076] Specifically, when the vehicle air conditioner is in internal circulation mode, the vehicle's air quality parameters are monitored, such as those collected by an air quality control system (AQS). When the air quality parameters fall below a preset threshold, the vehicle air conditioner's air conditioner mode is adjusted to external circulation mode. Once the air quality parameters rise above the preset threshold, the vehicle air conditioner's air conditioner mode is adjusted to internal circulation mode. This improves the user experience.

[0077] In some embodiments, for fuel vehicles, the vehicle air conditioner can use engine heat for heating to reduce the energy consumption generated by the heating of the air conditioner compressor.

[0078] Specifically, when the vehicle's air conditioner is in heating mode, if the vehicle's engine is not running, the air conditioner's compressor is controlled to start heating. If the vehicle's engine is running, the air conditioner's compressor is controlled to stop heating, and the air conditioner uses engine heat for heating. This can reduce the energy consumption of the air conditioner.

[0079] In some embodiments, when the vehicle air conditioner is just turned on, hot / cold air may remain in the air conditioning duct, which may cause discomfort to the user. To address this, the following steps may be performed to improve the user experience.

[0080] Specifically, when the car air conditioner is turned on, the air outlet is adjusted to face away from the seat, for example, upward and toward the doors and windows on both sides, and maintained for a preset duration, such as 30-60 seconds. After the remaining air in the air conditioning duct is purged, the control strategy for the air outlet orientation mentioned above is applied again. This avoids the discomfort caused by residual air blowing directly into the air conditioning duct, greatly improving the user experience.

[0081] It is worth mentioning that the above-mentioned multiple control processes for the vehicle air conditioner can be activated in a variety of ways. For example, a corresponding switch can be configured on the vehicle, such as setting the switch in the air conditioning or vehicle control interface to turn on or off the above-mentioned control process of the vehicle air conditioner. Alternatively, the above-mentioned control process of the vehicle air conditioner can be turned on or off by voice. Alternatively, a corresponding soft key can be added to the vehicle's shortcut panel, and the above-mentioned control process of the vehicle air conditioner can be turned on or off with one click through the soft key.

[0082] In an embodiment of the present application, when a vehicle's onboard air conditioner is operating, it can monitor temperature parameters such as the vehicle's cabin temperature and automatically adjust the air conditioner's temperature based on the relationship between the monitored cabin temperature and a user-set temperature. Specifically, if the absolute value of the difference between the cabin temperature and the vehicle's user-set temperature is greater than or equal to a preset temperature threshold, the air conditioner's temperature is set to the difference between the user-set temperature and a preset value if the cabin temperature is lower than the user-set temperature; and to the sum of the user-set temperature and the preset value if the cabin temperature is higher than the user-set temperature. This allows the relationship between the cabin temperature and the user-set temperature to be used to predict the risk of a cold caused by the temperature difference between the inside and outside of the vehicle when the user enters or exits the vehicle. The air conditioner's temperature can then be adjusted in advance to reduce the temperature difference, thereby minimizing the risk of a cold for the user when entering or exiting the vehicle, significantly improving the user experience.

[0083] In addition, the embodiment of the present invention can also control the direction of the air outlet or the air outlet mode of the vehicle air conditioner according to the temperature parameters of the vehicle, further improving the user experience of the vehicle air conditioner and reducing the energy consumption of the vehicle air conditioner, achieving the effect of energy saving and reducing the burden of manual operation, helping fuel vehicles and new energy vehicles to reduce energy consumption, improve economic applicability, and greatly improve the control effect of the vehicle air conditioner.

[0084] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.
