[0046] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0047] The vehicle air conditioning control method provided in the embodiment of the present application can be applied to Figure 1 The application environment shown in the figure, wherein the sensor 102, the mixing damper 104, the blower 106, the mode damper 108, the compressor 110 and the air-conditioning controller 112 are connected through a bus; the in-vehicle temperature, the ambient temperature and the light intensity are obtained through the sensor 102, and the control value is determined by the air-conditioning controller 112 based on the set temperature, the in-vehicle temperature, the ambient temperature and the light intensity. The air-conditioning controller 112 determines the on / off state of the compressor 110 through the ambient temperature and the control value, the air-conditioning controller 112 determines the circulation mode of the mode damper 108 through the ambient temperature and the control value, the air-conditioning controller 1112 determines the damper opening of the mixing damper 104 through the control value, and the air-conditioning controller 112 determines the air volume level of the blower 106 through the control value.

[0048] In one embodiment, Figure 2 As shown, a vehicle air conditioning control method is provided, and the method is applied to Figure 1 The air conditioning controller in the example is used to illustrate, including the following steps:

[0049] S202, obtaining a set temperature, an interior temperature of the vehicle, an ambient temperature, and light intensity, and determining a control value based on the set temperature, the interior temperature of the vehicle, the ambient temperature, and the light intensity.

[0050] The set temperature is the temperature set by the driver, that is, the temperature the driver expects the vehicle to reach. The vehicle interior temperature is the real-time temperature of the vehicle cockpit, the ambient temperature is the real-time temperature of the vehicle's external environment, and the light intensity is the real-time light intensity of the vehicle's external environment.

[0051] Specifically, when the air conditioner of the vehicle is in the automatic control mode, the air conditioner control method of the vehicle in the embodiment of the present application is executed. The air conditioner controller obtains the vehicle temperature Tin through the temperature sensor arranged in the cockpit, specifically, the vehicle temperature Tin can be obtained through the temperature sensor arranged at the outlet of the internal circulation air outlet; the ambient temperature Tout can be obtained through the sensor arranged outside the vehicle; and the light intensity can be obtained through the light intensity sensor arranged on the dashboard.

[0052] The air conditioning controller obtains the reference temperature, and calculates the control value through a comprehensive operation formula according to the reference temperature, the set temperature, the temperature inside the vehicle, the ambient temperature and the light intensity. The control value is determined by comprehensively considering the difference between the reference temperature and the set temperature, the difference between the set temperature and the temperature inside the vehicle, the ambient temperature compensation corresponding to the ambient temperature, and the light compensation corresponding to the light intensity. The reference temperature is a pre-set temperature, for example, the reference temperature is 25°C.

[0053] In some embodiments, a control value is determined based on a set temperature, an in-vehicle temperature, an ambient temperature and light intensity, including: obtaining a reference temperature, a set temperature deviation gain, an in-vehicle temperature deviation gain and a control constant; calculating a set temperature deviation between the set temperature and the reference temperature; calculating an in-vehicle temperature deviation between the set temperature and the in-vehicle temperature; querying an ambient temperature compensation corresponding to the ambient temperature; querying a light compensation corresponding to the light intensity; determining a control value based on the set temperature deviation, the temperature deviation gain, the in-vehicle temperature deviation, the in-vehicle temperature deviation gain, the ambient temperature compensation, the light compensation and the control constant.

[0054] Specifically, a mapping relationship between the ambient temperature and the ambient temperature compensation is preset, and based on the mapping relationship between the ambient temperature and the ambient temperature compensation, the ambient temperature compensation corresponding to the ambient temperature is queried; the ambient temperature is positively correlated with the ambient temperature compensation.

[0055] In one implementation, when the ambient temperature is less than the first minimum temperature, the ambient temperature compensation corresponding to the ambient temperature is the preset minimum temperature compensation, and when the ambient temperature is greater than the maximum temperature, the ambient temperature compensation corresponding to the ambient temperature is the preset maximum temperature compensation; when the ambient temperature is greater than or equal to the first minimum temperature and less than or equal to the maximum temperature, the change in the ambient temperature is proportional to the change in the ambient temperature compensation. For example, when the ambient temperature belongs to the first temperature compensation interval, the ratio between the change in the ambient temperature and the change in the ambient temperature compensation is 3:8, when the ambient temperature belongs to the second temperature compensation interval, the ratio between the change in the ambient temperature and the change in the ambient temperature compensation is 1:4, and when the ambient temperature belongs to the third temperature compensation interval, the ratio between the change in the ambient temperature and the change in the ambient temperature compensation is 2:3; when the ambient temperature is 25°C, the ambient temperature compensation is 0. The ambient temperature in the first temperature compensation interval is greater than the ambient temperature in the second temperature compensation interval, and the ambient temperature in the second temperature compensation interval is greater than the ambient temperature in the third temperature compensation interval.

[0056] Exemplarily, the first temperature compensation interval may be (10°C, 45°C], the second temperature compensation interval may be (0°C, 10°C], the third temperature compensation interval may be (-40°C, 0°C], the first minimum temperature may be -40°C, the maximum temperature may be 45°C, the preset minimum temperature compensation is -140, and the preset maximum temperature compensation is 60.

[0057] Exemplarily, the mapping relationship between the ambient temperature and the ambient temperature compensation (K3) is as follows: Figure 3 As shown, when the ambient temperature is less than minus 40°C, the ambient temperature compensation K3 is -140; when the ambient temperature is 0°C, the ambient temperature compensation is -80; when the ambient temperature is 25°C, the ambient temperature compensation K3 is 0; when the ambient temperature is greater than 45°C, the ambient temperature compensation K3 is 60.

[0058] A mapping relationship between light intensity and light compensation is preset, and based on the mapping relationship between light intensity and light compensation, light compensation corresponding to light intensity is queried; light intensity is positively correlated with light compensation.

[0059] In one implementation, when the illumination intensity is less than the minimum illumination intensity, the illumination compensation corresponding to the illumination intensity is the preset minimum illumination compensation, and when the illumination intensity is greater than the maximum illumination intensity, the illumination compensation corresponding to the illumination intensity is the preset maximum illumination compensation; when the illumination intensity is greater than or equal to the minimum illumination intensity, and less than or equal to the maximum illumination intensity, the change in illumination intensity is proportional to the change in illumination compensation. For example, when the illumination intensity belongs to the first illumination compensation interval, the ratio between the change in illumination intensity and the change in illumination compensation is 1:1, when the illumination intensity belongs to the second illumination compensation interval, the ratio between the change in illumination intensity and the change in illumination compensation is 6:5, when the illumination intensity belongs to the third illumination compensation interval, the ratio between the change in illumination intensity and the change in illumination compensation is 10:1, when the illumination intensity belongs to the fourth illumination compensation interval, the ratio between the change in illumination intensity and the illumination compensation is 5:2, and when the illumination intensity belongs to the fifth illumination compensation interval, the ratio between the change in illumination intensity and the illumination compensation is 7:1. The light intensity in the first light compensation interval is greater than the light intensity in the second light compensation interval, the light intensity in the second light compensation interval is greater than the light intensity in the third light compensation interval, the light intensity in the third light compensation interval is greater than the light intensity in the fourth light compensation interval, and the light intensity in the fourth light compensation interval is greater than the light intensity in the fifth light compensation interval.

[0060] Exemplarily, the first illumination compensation interval may be (230lx, 245lx], the second illumination compensation interval may be (200lx, 230lx], the third illumination compensation interval may be (150lx, 200lx], the fourth illumination compensation interval may be (125lx, 150lx], the fifth illumination compensation interval may be (95lx, 125lx], the maximum illumination intensity is 145lx, the minimum illumination intensity is 90lx, the preset minimum illumination compensation is -60, and the preset maximum temperature compensation is 0.

[0061] Exemplarily, the mapping relationship between light intensity and light compensation (K4) is as follows: Figure 4 As shown, when the light intensity is less than or equal to 90 lx, the light compensation K4 is -60, and when the light intensity is greater than or equal to 240 lx, the light compensation K4 is 0.

[0062] S204, determining the on / off state of the compressor based on the ambient temperature and the control value; the on / off state is an open state or a closed state.

[0063] Specifically, the air conditioning controller pre-divides the ambient temperature into a plurality of temperature intervals, and pre-divides the control value into a plurality of control value intervals, and sets the on / off state of the compressor accordingly for different combinations of the plurality of temperature intervals and the plurality of control value intervals.

[0064] The air conditioning controller determines the temperature interval to which the ambient temperature belongs and the control value interval to which the control value belongs, and determines the on / off state of the compressor according to the temperature interval to which the ambient temperature belongs and the control value interval to which the control value belongs.

[0065] S206, determining a circulation mode of the mode damper based on the ambient temperature and the control value; the circulation mode is an internal circulation mode or an external circulation mode.

[0066] Specifically, the air conditioning controller sets the circulation mode of the mode damper accordingly for different combinations of multiple temperature intervals and multiple control value intervals in advance.

[0067] The air conditioning controller determines a temperature interval to which the ambient temperature belongs and a control value interval to which the control value belongs, and determines a circulation mode of the mode damper according to the temperature interval to which the ambient temperature belongs and the control value interval to which the control value belongs.

[0068] S208, determining a target air valve opening corresponding to the control value according to a preset air valve opening mapping relationship, and setting the air valve opening of the mixing air valve as the target air valve opening.

[0069] Specifically, the preset damper opening mapping relationship is used to reflect the mapping relationship between the damper opening of the mixing damper and the control value. When the control value TD is less than the first minimum control value, the damper opening of the mixing damper is 180°. When the control value TD is greater than the first maximum control value, the damper opening of the mixing damper is 0°. When the control value TD is less than the first maximum control value and greater than the first minimum control value, the larger the control value TD is, the smaller the damper opening is. When the damper opening is 180°, the mixing damper is in a fully cold state. When the damper opening is 0°, the mixing damper is in a fully warm state.

[0070] The first minimum control value and the first maximum control value can be set according to the actual situation of the vehicle. For example, the preset throttle opening mapping relationship can be as follows: Figure 5 As shown, the first minimum control value can be 35, and the first maximum control value can be 242. When the control value TD is less than 35, the damper opening of the mixing damper is 180°. When the control value TD is greater than 242, the damper opening of the mixing damper is 0°. The embodiment of the present application does not limit the first minimum control value and the first maximum control value.

[0071] S210, determining a target air volume level corresponding to the control value according to a preset air volume mapping relationship, and setting the air volume level of the blower as the target air volume level.

[0072] Specifically, the preset air volume mapping relationship is used to reflect the mapping relationship between the air volume level of the blower and the control value. In practical applications, the preset air volume mapping relationship can be Figure 6 As shown, when the control value TD is less than the second minimum control value, the air volume level is the maximum air volume level; when the control value TD is greater than the second maximum control value, the air volume level is the maximum air volume level; when the control value TD is equal to the first preset control value, the air volume level is the minimum air volume level; the first preset control value is less than the second maximum control value and greater than the second minimum control value; when the control value TD is less than the first preset control value and greater than the second minimum control value, the larger the control value TD is, the smaller the air volume level is; when the control value TD is greater than the first preset control value and less than the second maximum control value, the larger the control value TD is, the larger the air volume level is.

[0073] The second minimum control value, the second maximum control value and the first preset control value can be set according to the actual situation of the vehicle. For example, Figure 6 As shown, the second minimum control value is 10, the second maximum control value can be 250, the first preset control value can be 110, the minimum air volume level is level 1, and the maximum air volume level is level 8. When the control value is less than 10, the air volume level is level 8, when the control value is 110, the air volume level is level 1, and when the control value is greater than 250, the air volume level is level 8; when the control value is between 10 and 110, the air volume level is negatively correlated with the control value, and when the control value is between 110 and 250, the air volume level is positively correlated with the control value. The embodiment of the present application does not limit the second minimum control value, the second maximum control value, and the first preset control value.

[0074] In the air conditioning control method of the above-mentioned vehicle, the control value is determined according to the set temperature, the temperature inside the vehicle, the ambient temperature and the light intensity; the opening and closing state of the compressor is determined according to the ambient temperature and the control value, the circulation mode of the mode damper is determined, the damper opening of the mixing damper, and the air volume level of the blower are determined according to the control value; the opening and closing state of the compressor, the circulation mode of the mode damper, the damper opening of the mixing damper, and the air volume level of the blower can be adjusted in real time according to the actual driving environment of the vehicle, thereby improving the accuracy of the temperature regulation inside the vehicle and adapting to complex and changeable temperature environments.

[0075] In some embodiments, a control value is determined based on a set temperature, an in-vehicle temperature, an ambient temperature and light intensity, including: obtaining a reference temperature, a set temperature deviation gain, an in-vehicle temperature deviation gain and a control constant; calculating a set temperature deviation between the set temperature and the reference temperature; calculating an in-vehicle temperature deviation between the set temperature and the in-vehicle temperature; querying an ambient temperature compensation corresponding to the ambient temperature; querying a light compensation corresponding to the light intensity; determining a control value based on the set temperature deviation, the temperature deviation gain, the in-vehicle temperature deviation, the in-vehicle temperature deviation gain, the ambient temperature compensation, the light compensation and the control constant.

[0076] Specifically, the temperature deviation gain, the in-vehicle temperature deviation and the control constant are all custom settings. The smaller the control constant, the stronger the cooling performance of the air conditioner, and the larger the control constant, the stronger the heating performance of the air conditioner.

[0077] The air conditioning controller calculates the control value according to the comprehensive operation formula, which is as follows:

[0078] TD=K1(Tset-Tori)+K2(Tset-Tin)-K3+K4+OFFSET (1)

[0079] Wherein, K1 is the temperature deviation gain, Tset is the set temperature, Tori is the reference temperature, K2 is the in-vehicle temperature deviation gain, Tin is the in-vehicle temperature, K3 is the ambient temperature compensation, K4 is the light compensation, OFFSET is the control constant, and TD is the control value. For example, the temperature deviation gain K1 is 5, the in-vehicle temperature deviation gain K2 is 6, the reference temperature Tori is 25°C, and the control constant OFFSET is 117.

[0080] In some embodiments, the air conditioning controller obtains a reference temperature, and controls the on and off state of the compressor according to the reference temperature, the set temperature, the ambient temperature and the control value, including: when the ambient temperature belongs to a first preset ambient temperature range and the control value belongs to a first preset control range, the compressor is controlled to be in an off state; when the ambient temperature belongs to the first preset ambient temperature range and the control value belongs to a second preset control range, the compressor is controlled to be in an on state; when the ambient temperature belongs to the second preset ambient temperature range, the compressor is controlled to be in an on state; the temperature within the first preset ambient temperature range is lower than the temperature within the second preset ambient temperature range, and the control value within the first preset control range is higher than the control value within the second preset control range.

[0081] Specifically, the first preset ambient temperature interval can be (-∞, 3°C), the second preset ambient temperature interval can be (5°C, +∞), the first preset control interval can be (165, +∞), and the second preset control interval can be (-∞, 158); that is, when the ambient temperature is less than 3°C and the control value is greater than 165, the compressor is controlled to be in the off state; when the ambient temperature is less than 3°C and the control value is less than 158, the compressor is controlled to be in the on state; when the ambient temperature is greater than 5 degrees Celsius, the control value is in the on state.

[0082] In some embodiments, when the ambient temperature belongs to the fourth preset ambient temperature interval, the previous on-off state of the compressor is obtained, and the compressor is controlled to be in the previous on-off state, where the previous on-off state is the on-off state of the compressor before the ambient temperature belongs to the fourth preset ambient temperature interval. That is, when the ambient temperature belongs to the fourth preset ambient temperature interval, the compressor maintains the previous on-off state.

[0083] The temperature in the fourth preset ambient temperature range is greater than the temperature in the first preset ambient temperature range and less than the temperature in the second preset ambient temperature range.

[0084] Exemplarily, the fourth preset ambient temperature interval may be [3°C, 5°C]. If at time t1, the ambient temperature is 1°C and the control value is 152, the compressor is controlled to be in the open state; if at time t2, the ambient temperature is 3°C, the compressor is controlled to remain in the open state; if at time t1, the ambient temperature is 6°C and the control value is 170, the compressor is controlled to be in the closed state; if at time t2, the ambient temperature is 3°C, the compressor is controlled to remain in the closed state.

[0085] In some embodiments, the vehicle's air conditioning control method also includes: when the ambient temperature belongs to the fifth preset ambient temperature range, prohibiting the compressor output; when the ambient temperature belongs to the sixth preset ambient temperature range, allowing the compressor output; when the ambient temperature belongs to the seventh preset ambient temperature range, controlling the compressor to maintain the previous open or close state.

[0086] Specifically, prohibiting compressor output means that the compressor is not working, and allowing compressor output means that the compressor is working. When compressor output is prohibited, the compressor is unavailable and the opening and closing states cannot be adjusted. When compressor output is allowed, the opening and closing states of the compressor can be controlled.

[0087] Exemplarily, the fifth preset ambient temperature interval may be (-∞, -5°C), the sixth preset ambient temperature interval may be (-2°C, +∞), and the seventh preset ambient temperature interval may be [-5°C, -2°C].

[0088] Since the compressor is allowed to work when the ambient temperature is (-2°C, +∞), and since the compressor is controlled to be in the on state when the ambient temperature is in the first preset ambient temperature range (-∞, 3°C) and the control value belongs to the second preset control range, therefore, when the ambient temperature is (-2°C, 3°C) and the control value belongs to the second preset control range, the compressor is controlled to be in the on state.

[0089] For example, when the ambient temperature is less than -5℃, the compressor does not work; when the ambient temperature is (-2℃, 3℃) and the control value is in the second preset control interval, the compressor is controlled to be in the on state; when the ambient temperature is (-2℃, 3℃) and the control value is in the first preset control interval, the compressor is controlled to be in the off state. When the ambient temperature is [-5℃, -2℃], the compressor is controlled to maintain the previous on-off state.

[0090] In some embodiments, the vehicle's air conditioning control method also includes: obtaining the evaporator surface temperature, and when the evaporator surface temperature is greater than a first preset surface temperature, allowing the compressor output; when the evaporator surface temperature is less than a second preset surface temperature, prohibiting the compressor output; when the evaporator surface temperature is less than or equal to the first preset surface temperature and greater than or equal to the second preset surface temperature, controlling the compressor to maintain the previous open or close state.

[0091] Specifically, a temperature sensor is set on the surface of the evaporator, and the surface temperature of the evaporator is collected by the temperature sensor. For example, the first preset surface temperature is 5°C, and the second preset surface temperature is 3°C. When the surface temperature of the evaporator is (5°C, +∞), the compressor is allowed to work. When the surface temperature of the evaporator is (-∞, 3°C), the compressor output is prohibited. When the surface temperature of the evaporator is [3°C, 5°C], the compressor is controlled to maintain the last open and close state.

[0092] Since the compressor is allowed to work when the evaporator surface temperature is (5℃, +∞), and since the compressor is allowed to work when the ambient temperature is (-2℃, +∞), the compressor is controlled to be in the on state when the ambient temperature belongs to the first preset ambient temperature range (-∞, 3℃), and the control value belongs to the second preset control range. Therefore, when the evaporator surface temperature is (5℃, +∞), the ambient temperature belongs to (-2℃, 3℃), and the control value belongs to the second preset control range, the compressor is controlled to be in the on state.

[0093] When the evaporator surface temperature is (-∞, 3℃) or the ambient temperature is (-∞, -5℃), the controller does not work.

[0094] In some embodiments, the vehicle's air conditioning control method also includes: when the set temperature is a preset minimum temperature, the damper opening of the mixing damper is controlled to be the maximum opening, the air outlet mode is controlled to be the face blowing mode, the circulation mode is controlled to be the internal circulation, the air volume level of the blower is adjusted to the maximum air volume level, and the compressor is controlled to be in the on state; when the set temperature is a preset maximum temperature, the damper opening is controlled to be the minimum opening, the air outlet mode is controlled to be the foot blowing mode, the circulation mode is controlled to be the external circulation, the air volume level is adjusted to the maximum air volume level, and the compressor is controlled to be in the off state.

[0095] Specifically, when the set temperature is the preset minimum temperature (LO), the air conditioner enters the maximum cooling state, controls the damper opening of the mixed damper to the maximum opening (for example, the damper opening is 180°), controls the compressor to be in the on state, and the blowing mode is the face blowing mode, the circulation mode is the internal circulation, and the air volume level is the maximum air volume level. When the set temperature is the preset maximum temperature (HI), the air conditioner enters the maximum heating state, controls the mixing damper opening to the minimum opening (for example, the damper opening is 0°), controls the treatment mode to the foot blowing mode, the circulation mode is the external circulation, and the air volume level is the maximum air volume level.

[0096] In some embodiments, based on the ambient temperature and the control value, the circulation mode is determined, including: when the ambient temperature belongs to the first preset ambient temperature interval, the circulation mode is determined to be an external circulation mode; when the ambient temperature belongs to the third preset ambient temperature interval, the circulation mode is determined to be an internal circulation mode; when the ambient temperature does not belong to the first preset ambient temperature interval and the third preset ambient temperature interval, and the control value belongs to the first preset control interval, the control circulation mode is determined to be the internal circulation mode; when the ambient temperature does not belong to the first preset ambient temperature interval and the third preset ambient temperature interval, and the control value belongs to the third preset control interval, the control circulation mode is determined to be the external circulation mode; when the ambient temperature does not belong to the first preset ambient temperature interval and the third preset ambient temperature interval, and the control value satisfies the state holding condition, the previous mode is obtained, and the circulation mode is determined to be the previous mode; the previous mode is the circulation mode before the control value satisfies the state holding condition.

[0097] Exemplarily, the first preset ambient temperature interval may be (-∞, 3°C), the third preset ambient temperature interval may be (25°C, +∞), and when the ambient temperature does not belong to the first preset ambient temperature interval and the third preset ambient temperature interval, the ambient temperature may be [3°C, 25°C]; the first preset control interval may be (165, +∞), and the third preset control interval may be (-∞, 145).

[0098] The control value satisfies the state condition, which means that the control value does not belong to the first preset control interval and the third preset control interval. For example, the first preset control interval may be (-∞,145), and the third preset control interval may be (165,+∞). When the control value belongs to [145,165], the control value satisfies the state condition.

[0099] When the ambient temperature is (-∞,3℃), the circulation mode is determined to be the external circulation mode; when the ambient temperature is (25℃,+∞), the circulation mode is determined to be the internal circulation mode; when the ambient temperature is [3℃,25℃] and the control value is (165,+∞), the circulation mode is determined to be the internal circulation mode; when the ambient temperature is [3℃,25℃] and the control value is (-∞,145), the circulation mode is determined to be the external circulation mode; when the ambient temperature is [3℃,25℃] and the control value is [145,165], the circulation mode is determined to be the previous mode.

[0100] For example, Figure 7 As shown, when the ambient temperature is [3℃, 25℃], at time t1, the control value is (-∞, 145), and the circulation mode is the internal circulation mode, corresponding to Figure 7 In area 1, at time t2, the control value belongs to [145,165], and the cycle mode is the inner cycle mode (maintaining the cycle mode at time t1), corresponding to Figure 7 in area 2.

[0101] At time t3, the control value belongs to (165, +∞), and the circulation mode is the external circulation mode, corresponding to Figure 7 In area 3, at time t4, the control value belongs to [145,165], and the circulation mode is the external circulation mode (maintaining the circulation mode at time t3), corresponding to Figure 7 in area 4.

[0102] In some embodiments, when the circulation mode is in the internal circulation mode for a first preset time, the circulation mode is controlled to switch to the external circulation mode, and when the circulation mode is in the external circulation mode for a second preset time, the circulation mode is controlled to switch to the internal circulation mode.

[0103] Exemplarily, the first preset time length may be 15 minutes, and the second preset time length may be 1 minute.

[0104] In some embodiments, the vehicle's air conditioning control method also includes: when the ambient temperature is in a preset summer temperature range, obtaining the face air outlet temperature; when the face air outlet temperature is greater than the first preset face temperature, and the air outlet mode is the face mode, switching the air outlet mode to the face and foot mode; when the face air outlet temperature is less than or equal to the second preset face temperature, and the air outlet mode is the face and foot mode, switching the air outlet mode to the face mode; when the face air outlet temperature is less than or equal to the first preset face temperature, and greater than the second preset face temperature, maintaining the previous air outlet mode.

[0105] Specifically, the previous air outlet mode is an air outlet mode before the temperature of the blowing surface air outlet is less than or equal to the first preset blowing surface temperature and greater than the second preset blowing surface temperature.

[0106] For example, the preset summer temperature range may be [25° C., +∞), the first preset blowing surface temperature may be 28° C., and the second preset blowing surface temperature may be 24° C. When the ambient temperature is in the preset summer temperature range, the air outlet mode is controlled according to Table 1.

[0108] Air outlet mode Air outlet temperature Tv Switch to mode Blowing mode Tv>28℃ Face and feet blowing mode Face and feet blowing mode Tv≤24℃ Blowing mode Any Mode 24℃<Tv≤28℃ Keep the previous air flow mode

[0109] When the face-blowing air outlet temperature Tv>28℃ and the air outlet mode is the face-blowing mode, the air outlet mode is switched to the face-blowing and foot-blowing mode; when Tv≤24℃, when 24℃<Tv≤28℃, the previous air outlet mode is maintained.

[0110] In some embodiments, when the ambient temperature is in a preset spring and autumn temperature range, the air outlet mode is obtained, and when the air outlet mode is the face blowing mode, the face blowing air outlet temperature is obtained, and when the face blowing air outlet temperature is in a first preset face blowing temperature range, the air outlet mode is switched to the face blowing foot blowing mode, and when the face blowing air outlet temperature is in a second preset face blowing temperature range, the air outlet mode is switched to the foot blowing mode;

[0111] When the air outlet mode is the face-blowing and foot-blowing mode, the face-blowing air outlet temperature and the foot-blowing air outlet temperature are obtained, and when the face-blowing air outlet temperature is in the second preset face-blowing temperature interval, the air outlet mode is switched to the foot-blowing mode, and when the foot-blowing air outlet temperature is in the first preset foot-blowing temperature interval, the air outlet mode is switched to the face-blowing mode;

[0112] When the air outlet mode is the foot blowing mode, obtain the foot blowing air outlet temperature. When the foot blowing air outlet temperature is in the second preset foot blowing temperature range, switch the air outlet mode to the face blowing foot blowing mode. When the foot blowing air outlet temperature is in the first preset foot blowing temperature range, switch the air outlet mode to the face blowing mode.

[0113] Exemplarily, the first preset blowing face temperature interval is (25°C, 35°C), the second preset blowing face temperature interval is [35°C, +∞), the first preset blowing foot temperature interval is (-∞, 20°C), and the second preset blowing foot temperature interval is [20°C, 30°C). When the ambient temperature is in the preset spring and autumn temperature interval, the air outlet mode is controlled according to Table 2.

[0116] In some embodiments, when the ambient temperature is in a preset winter temperature range, the temperature of the foot-blowing air outlet is obtained; when the temperature of the foot-blowing air outlet is in the third preset foot-blowing temperature range, and the air outlet mode is the foot-blowing mode, the air outlet mode is switched to the face-blowing and foot-blowing mode; when the temperature of the foot-blowing air outlet is in the fourth preset foot-blowing temperature range, and the air outlet mode is the face-blowing and foot-blowing mode, the air outlet mode is switched to the foot-blowing mode; when the temperature of the foot-blowing air outlet is in the fifth preset foot-blowing temperature range, the previous air outlet mode is maintained.

[0117] Exemplarily, the third preset foot blowing temperature interval may be (-∞, 22°C], the fourth preset foot blowing temperature interval may be (25°C, +∞], and the fifth preset foot blowing temperature interval may be (22°C, 25°C]. When the ambient temperature is in the preset winter temperature interval, the air outlet mode is controlled according to Table 3.
