[0027] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0028] The following describes the control method, device, vehicle and storage medium of the vehicle air conditioner of the embodiment of the present application with reference to the accompanying drawings. In view of the problems mentioned in the background technology center above, such as the slow rise of water temperature in winter, the deviation of air conditioning heating effect, the slow cooling speed in summer, the large noise of air conditioning blower when the vehicle is idling, and the high fuel consumption, the present application provides a control method of vehicle air conditioning, in which the current humidity of the vehicle interior environment and the current water temperature of the engine are collected by detecting the current operation mode of the vehicle air conditioner when the current operation mode of the vehicle air conditioner is the heating mode, the current optimal circulation mode of the vehicle air conditioner is matched according to the current humidity and current water temperature of the vehicle interior environment, and the vehicle air conditioner is controlled according to the current optimal circulation mode. Thus, the problems such as the slow rise of water temperature in winter, the deviation of air conditioning heating effect, the slow cooling speed in summer, the large noise of air conditioning blower when the vehicle is idling, and the high fuel consumption are solved, and the air conditioner is quickly put into a comfortable state, the noise in the vehicle when the vehicle is idling is reduced, and the purpose of saving fuel is achieved.

[0029] Specifically, Figure 1 A flow chart of a method for controlling a vehicle air conditioner provided in an embodiment of the present application.

[0030] like Figure 1 As shown, the control method of the vehicle air conditioner includes the following steps:

[0031] In step S101 , the current operation mode of the vehicle air conditioner is detected.

[0032] The operation mode may include a heating mode and a cooling mode.

[0033] Specifically, if the vehicle air conditioner is in the heating mode, it is detected that the current operating mode of the vehicle air conditioner is the heating mode; if the vehicle air conditioner is in the cooling mode, it is detected that the current operating mode of the vehicle air conditioner is the cooling mode.

[0034] In step S102, when the current operation mode of the vehicle air conditioner is the heating mode, the current humidity of the vehicle interior environment and the current water temperature of the engine are collected.

[0035] Specifically, when the current operating mode of the air conditioner is the heating mode, the embodiment of the present application can use the in-vehicle humidity sensor to detect the humidity of the in-vehicle environment, and the in-vehicle temperature sensor to collect the current water temperature of the engine.

[0036] In step S103, the current optimal circulation mode of the vehicle air conditioner is matched according to the current humidity and the current water temperature of the vehicle interior environment, and the vehicle air conditioner is controlled according to the current optimal circulation mode.

[0037] Optionally, in some embodiments, the current optimal circulation mode of the vehicle air conditioner is matched according to the current humidity and current water temperature of the vehicle interior environment, including: if the current humidity of the vehicle interior environment is less than a first preset humidity, and the current water temperature is less than the first preset water temperature, then the current optimal circulation mode is to start the internal circulation according to the first preset ratio; if the current humidity of the vehicle interior environment is greater than or equal to the first preset humidity, and the current humidity is less than the second preset humidity, and the current water temperature is less than the first preset water temperature, then the current optimal circulation mode is to start the internal circulation according to the second preset ratio; if the current humidity of the vehicle interior environment is greater than or equal to the second preset humidity, and the current humidity is less than the third preset humidity, and the current water temperature is less than the first preset water temperature, then the current optimal circulation mode is to start the internal circulation according to the third preset ratio; if the current water temperature is greater than or equal to the first preset water temperature, then the current optimal circulation mode is the current circulation mode; wherein, the first preset ratio is greater than the second preset ratio, and the second preset ratio is greater than the third preset ratio.

[0038] Among them, the first preset humidity, the first preset ratio, the first preset water temperature, the second preset humidity, the third preset humidity, the second preset ratio and the third preset ratio can be threshold values ​​preset by the user, can be threshold values ​​obtained through a limited number of experiments, or can be threshold values ​​obtained through a limited number of computer simulations, and are not specifically limited here. Preferably, the first preset humidity is set to 60%, the first preset water temperature is set to 80°C, the second preset humidity is set to 70%, the third preset humidity is set to 80%, the first preset ratio is set to 100%, the second preset ratio is set to 70%, and the third preset ratio is set to 50%.

[0039] Specifically, Figure 2 As shown, when the current humidity of the collected in-car environment is less than 60%, and the current water temperature is less than 80°C, the current optimal circulation mode is to turn on 100% internal circulation; if the current humidity of the in-car environment is greater than or equal to 60%, and the current humidity is less than 70%, and the current water temperature is less than 80°C, then the current optimal circulation mode is to turn on 70% internal circulation; if the current humidity of the in-car environment is greater than or equal to 70%, and the current humidity is less than 80%, and the current water temperature is less than 80°C, then the current optimal circulation mode is to turn on 50% internal circulation; if the current water temperature is greater than or equal to 80°C, the air conditioner is controlled to maintain the current state.

[0040] Furthermore, the embodiment of the present application can use a facial recognition sensor to detect whether there is someone in the car. When there is no one in the car, the humidity will not continue to increase, and the air conditioning can be kept at 100% internal circulation. Moreover, under this working condition, since the vehicle speed is 0, the heat exchange with the outside world is small, which is more conducive to the rapid increase of water temperature.

[0041] Furthermore, in some embodiments, the above-mentioned vehicle air-conditioning control method also includes: when the current operating mode of the vehicle air-conditioning is a cooling mode, collecting the current temperature in the vehicle and the current ambient temperature of the vehicle; if the current temperature is greater than the current ambient temperature, controlling the vehicle air-conditioning to start the external circulation, otherwise, controlling the vehicle air-conditioning to start the internal circulation.

[0042] Specifically, Figure 3 As shown, when the current operating mode of the air conditioner is the cooling mode, the current temperature inside the vehicle is collected through the in-vehicle temperature sensor, and the current ambient temperature of the vehicle is collected through the ambient temperature sensor. If the current temperature is greater than the current ambient temperature, the air conditioner is controlled to start external circulation ventilation, otherwise, the air conditioner is controlled to start full internal circulation.

[0043] Optionally, in some embodiments, the above-mentioned vehicle air-conditioning control method also includes: detecting the current speed of the vehicle; if the current speed is 0 and the current temperature is in a preset temperature range, controlling the vehicle air-conditioning to reduce the air volume to a preset air volume, otherwise, controlling the vehicle air-conditioning to maintain the current state.

[0044] Specifically, Figure 4 As shown, the current speed of the vehicle is detected, and the temperature inside the vehicle is collected through the in-vehicle temperature sensor. If the current speed is 0 and the current temperature is in the preset temperature range, the air conditioner is controlled to reduce the air volume to the preset air volume. Otherwise, the air conditioner is controlled to maintain the current status to reduce the noise inside the vehicle when idling.

[0045] The preset temperature range and the preset air volume may be thresholds preset by a user, thresholds obtained through a limited number of experiments, or thresholds obtained through a limited number of computer simulations, which are not specifically limited here.

[0046] Optionally, in some embodiments, the above-mentioned vehicle air-conditioning control method also includes: determining whether the current humidity of the vehicle interior environment is greater than a preset fogging risk threshold; if the current humidity is greater than the preset fogging risk threshold, controlling the vehicle air-conditioning to turn on the compressor, otherwise, turning off the compressor.

[0047] Specifically, Figure 5 As shown, the current humidity in the car is detected by the humidity sensor in the car. If the current humidity is greater than the preset fogging risk threshold, the air conditioner is controlled to turn on the compressor. Otherwise, the compressor is turned off to avoid the user manually turning on the compressor. The user can concentrate on driving, realizing the automatic defogger function.

[0048] Among them, the preset fogging risk threshold may be a threshold pre-set by a user, a threshold obtained through a limited number of experiments, or a threshold obtained through a limited number of computer simulations, and is not specifically limited here.

[0049] According to the control method of the vehicle air conditioner proposed in the embodiment of the present application, by detecting the current operating mode of the vehicle air conditioner, when the current operating mode of the vehicle air conditioner is the heating mode, the current humidity of the vehicle interior environment and the current water temperature of the engine are collected, the current optimal circulation mode of the vehicle air conditioner is matched according to the current humidity and current water temperature of the vehicle interior environment, and the vehicle air conditioner is controlled according to the current optimal circulation mode. Thus, the problems of the slow rise of water temperature in winter, the deviation of the air conditioning heating effect, the slow cooling speed in summer, the high noise of the air conditioning blower when the vehicle is idling, and the high fuel consumption are solved, and the purpose of quickly entering a comfortable state of the air conditioner, reducing the noise inside the vehicle when the vehicle is idling, and saving fuel at the same time is achieved.

[0050] Next, the control device for the vehicle air conditioner proposed in accordance with the embodiment of the present application will be described with reference to the accompanying drawings.

[0052] like Figure 6 As shown, the vehicle air conditioner control device 10 includes: a first detection module 100, a first acquisition module 200 and a first control module.

[0053] Among them, the first detection module 100 is used to detect the current operating mode of the vehicle air conditioner; the first acquisition module 200 is used to collect the current humidity of the vehicle interior environment and the current water temperature of the engine when the current operating mode of the vehicle air conditioner is the heating mode; the first control module 300 is used to match the current optimal circulation mode of the vehicle air conditioner according to the current humidity and the current water temperature of the vehicle interior environment, and control the vehicle air conditioner according to the current optimal circulation mode.

[0054] Optionally, the first control module 300 is specifically used to: if the current humidity of the interior environment of the vehicle is less than the first preset humidity, and the current water temperature is less than the first preset water temperature, then the current optimal circulation mode is to start the internal circulation according to the first preset ratio; if the current humidity of the interior environment of the vehicle is greater than or equal to the first preset humidity, and the current humidity is less than the second preset humidity, and the current water temperature is less than the first preset water temperature, then the current optimal circulation mode is to start the internal circulation according to the second preset ratio; if the current humidity of the interior environment of the vehicle is greater than or equal to the second preset humidity, and the current humidity is less than the third preset humidity, and the current water temperature is less than the first preset water temperature, then the current optimal circulation mode is to start the internal circulation according to the third preset ratio; if the current water temperature is greater than or equal to the first preset water temperature, then the current optimal circulation mode is the current circulation mode; wherein, the first preset ratio is greater than the second preset ratio, and the second preset ratio is greater than the third preset ratio.

[0055] Optionally, the above-mentioned vehicle air-conditioning control device 10 also includes: a second acquisition module, used to collect the current temperature in the vehicle and the current ambient temperature of the vehicle when the current operating mode of the vehicle air-conditioning is the cooling mode; a second control module, used to control the vehicle air-conditioning to start the external circulation if the current temperature is greater than the current ambient temperature, otherwise, control the vehicle air-conditioning to start the internal circulation.
