Description

Technical Field

[0001] The present application relates to the field of air-conditioning technology, and in particular to a vehicle and its air-conditioning, as well as a vehicle air-conditioning control method and device. Background Art

[0002] With the development of science and technology and social progress, cars have become more and more popular in people's lives. With the long-term use of cars, the filter element of the car air conditioner will absorb a lot of dust or particles and other impurities in the air. When the air conditioner filter element is dirty, the flow resistance of air flowing through the filter element will increase, resulting in a decrease in the air flow of the filter element and a decrease in the performance of the air conditioner. In this way, when the air quality in the car is good, the performance of the air conditioner cannot be fully utilized and cannot meet the user's demand for the temperature in the car. At the same time, when the car air conditioner is turned on, the air conditioner filter element is always running, which will also shorten the service life of the air conditioner filter element. Summary of the invention

[0003] The present application provides a vehicle and its air conditioner as well as a vehicle air conditioner control method and device to solve the problem that the air conditioner performance is not fully utilized and the air conditioner filter element has a short life.

[0004] In the first aspect, the present application provides a vehicle air conditioner, comprising: an air conditioning box shell provided with an air inlet damper and an air outlet damper, and a filter unit and a blower arranged in the air conditioning box shell; an air supply mechanism is also provided on the air conditioning box shell, and the air supply mechanism is located between the filter unit and the blower; wherein the air supply mechanism has a closed state and an open state, and when the air supply mechanism is in the open state, the air inside the vehicle enters the vehicle air conditioner through the air supply mechanism.

[0005] In traditional vehicle air conditioners, the air entering the vehicle air conditioner needs to pass through the filter unit before entering the air conditioning box. After impurities such as dust or particles adhere to the filter unit, the flow resistance of the air flowing through the filter unit will be greatly increased, resulting in a decrease in the air flow rate of the filter unit, which reduces the performance of the vehicle air conditioner and causes the performance of the vehicle air conditioner to not be fully utilized.

[0006] In the embodiment of the present application, an air supply mechanism is provided on the air conditioning box housing between the filter unit and the blower. When the air supply mechanism is in an open state, the air inside the vehicle can enter the air conditioning box of the vehicle air conditioner through the air supply mechanism without filtering the air inside the vehicle through the filter unit. The air inside the vehicle entering the air conditioning box from the air supply mechanism does not have a reduced ventilation volume due to flow resistance. Therefore, the embodiment of the present application can improve the performance of the vehicle air conditioner, so that the performance of the vehicle air conditioner can be more fully utilized.

[0007] Moreover, since the air supply mechanism is arranged between the filter unit and the blower, the air enters the vehicle air conditioner through the air supply mechanism and does not pass through the filter unit, so that the filter unit is not always in a working state, or the workload of the filter unit is reduced. Therefore, the embodiment of the present application can also increase the service life of the filter unit.

[0008] In a possible implementation, the air supply mechanism includes: an air supply vent provided on the air conditioner housing, and an air supply damper rotatably connected to the air conditioner housing, wherein a boss is provided on the inner side of the air supply damper, and the boss is embedded in the air supply vent after the air supply damper is closed.

[0009] In a possible implementation, a convex strip is provided on the outside of the boss on the inner side of the air supply damper, and a groove corresponding to the convex strip is provided on the edge of the air supply damper on the housing of the air conditioner.

[0010] Exemplarily, the depth of the groove is inversely proportional to the first distance, and the first distance is the distance from the groove to the rotation axis of the air supplement damper.

[0011] In a possible implementation, the air supply mechanism further includes: a motor connected to the rotating shaft of the air supply damper; a limiting mechanism disposed on the air conditioning box casing, wherein the limiting mechanism conflicts with the air supply damper after the air supply damper is opened to a preset angle.

[0012] In a possible implementation, the air supply mechanism includes a filter screen disposed on the air supply damper, and the air supply damper opens downward.

[0013] In a second aspect, the present application provides a vehicle air-conditioning control method, including: detecting whether the vehicle air-conditioning is turned on; if it is detected that the vehicle air-conditioning is turned on, obtaining air quality data of the air inside the vehicle; when the air quality data meets preset conditions, controlling the air supply mechanism to turn on, so that the air inside the vehicle enters the vehicle air-conditioning through the air supply mechanism.

[0014] In the embodiment of the present application, when the air quality data inside the vehicle meets the preset conditions, the air supply mechanism can be turned on so that the air inside the vehicle enters the vehicle air conditioner through the air supply mechanism without filtering the air inside the vehicle through the filter unit. After impurities such as dust or particles are attached to the filter unit, the flow resistance of the air flowing through the filter unit will be greatly increased, thereby resulting in a reduction in the air flow rate of the filter unit, which reduces the performance of the vehicle air conditioner and causes the performance of the vehicle air conditioner to be not fully utilized. Since the embodiment of the present application does not need to pass through the filter unit when the air supply mechanism is in the turned-on state, the air inside the vehicle enters the vehicle air conditioner without passing through the filter unit, and therefore the air flow rate will not be reduced due to the above-mentioned flow resistance, thereby improving the performance of the vehicle air conditioner and making more full use of the performance of the vehicle air conditioner.

[0015] In addition, since the air supply mechanism is arranged between the filter unit and the blower, the air enters the vehicle air conditioner through the air supply mechanism and does not pass through the filter unit, so that the filter unit is not always in a working state, or the workload of the filter unit is reduced. Therefore, the embodiment of the present application can also increase the service life of the filter unit.

[0016] In a possible implementation, when the air quality data meets the preset conditions, the air supply mechanism is controlled to be turned on, including: if the air quality data meets the preset conditions, obtaining glass fogging determination data; based on the above glass fogging determination data, determining whether there is a risk of fogging for the front windshield of the vehicle; if there is a risk of fogging, controlling the air supply mechanism to be turned on.

[0017] In a possible implementation, the above-mentioned control of the opening of the air supply mechanism includes: determining the opening angle of the air supply mechanism according to at least one of the vehicle air-conditioning panel temperature, the vehicle interior temperature, the vehicle exterior temperature, the vehicle air-conditioning evaporator temperature and the sunlight illumination inside the vehicle; and controlling the opening of the air supply mechanism based on the above-mentioned opening angle.

[0018] Exemplarily, the vehicle air conditioning panel temperature includes a panel setting temperature and a panel target comfort temperature, and the opening angle is proportional to the difference between the panel setting temperature and the panel target comfort temperature.

[0021] Exemplarily, the evaporator temperature includes an actual evaporator temperature and a target evaporator temperature, and the opening angle is proportional to the difference between the actual evaporator temperature and the target evaporator temperature.

[0022] Exemplarily, the above-mentioned sunlight illuminance includes current sunlight illuminance and sunlight illuminance target value. When the vehicle air conditioner turns on the cooling function, the opening angle is directly proportional to the difference between the current sunlight illuminance and the sunlight illuminance target value; when the vehicle air conditioner turns on the heating function, the opening angle is inversely proportional to the difference between the current sunlight illuminance and the sunlight illuminance target value.

[0023] In a possible implementation, the above-mentioned determination of the opening angle of the air supplement mechanism includes:

[0024] ASDOpen=a*|PanelTempSet-ComfortTemp|+b*|AmbTemp-ComfortAmbTemp|

[0025] +c*|InCarTempSet-InCarTempAct|+d*(SunAct-SunAmbtarget)

[0026] +e*(EvpSet-EvpAct)+f

Among them, ASDOpen represents the opening angle, PanelTempSet represents the panel set temperature, ComfortTemp represents the panel target comfort temperature, AmbTemp represents the actual temperature outside the vehicle, ComfortAmbTemp represents the target temperature outside the vehicle, InCarTempSet represents the actual temperature inside the vehicle, InCarTempAct represents the target temperature inside the vehicle, SunAct represents the current sunlight illumination, SunAmbtarget represents the target sunlight illumination value, EvpSet represents the evaporator target temperature, EvpAct represents the actual evaporator temperature, a, b, c, d and e are compensation coefficients, and f is a preset calibration value.

[0028] In a possible implementation, the method further includes: controlling an internal circulation damper of the vehicle air conditioner to close, and adjusting the vehicle air conditioner to an external circulation mode.

[0044] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also 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 prevent unnecessary details from obstructing the description of the present application.

[0045] In order to make the purpose, technical solutions and advantages of the present application clearer, specific embodiments will be described below in conjunction with the accompanying drawings.

[0046] Figure 1 This is a schematic diagram of the structure of the vehicle air conditioner provided in the embodiment of the present application. Figure 1 As shown, the vehicle air conditioner may include an air conditioner housing 100, a filter unit 200, a blower 300 and an air supply mechanism 400. The air conditioner housing 100 is provided with an air inlet damper and an air outlet damper, and the filter unit 200 and the blower 300 are both arranged in the air conditioner housing 100. The air supply mechanism 400 is arranged on the air conditioner housing 100 and is located between the filter unit 200 and the blower 300. The air supply mechanism 400 has a closed state and an open state. When the air supply mechanism 400 is in the open state, the air inside the vehicle enters the vehicle air conditioner through the air supply mechanism 400.

[0047] In traditional vehicle air conditioners, the air entering the vehicle air conditioner needs to pass through the filter unit before entering the air conditioning box. After impurities such as dust or particles adhere to the filter unit, the flow resistance of the air flowing through the filter unit will be greatly increased, resulting in a decrease in the air flow rate of the filter unit, which reduces the performance of the vehicle air conditioner and causes the performance of the vehicle air conditioner to not be fully utilized.

[0048] In the embodiment of the present application, an air supply mechanism 400 is provided on the air conditioning box housing 100 and is located between the filter unit 200 and the blower 300. When the air supply mechanism 400 is in an open state, the air inside the vehicle enters the vehicle air conditioning through the air supply mechanism 400, and does not need to be filtered by the filter unit 200. The air inside the vehicle entering the air conditioning box from the air supply mechanism 400 does not have a reduced ventilation volume due to flow resistance. Therefore, the embodiment of the present application can improve the performance of the vehicle air conditioning, so that the performance of the vehicle air conditioning can be more fully utilized.

[0049] In addition, since the air supply mechanism 400 is arranged between the filter unit 200 and the blower 300, the air enters the vehicle air conditioner through the air supply mechanism 400 and does not pass through the filter unit 200, so that the filter unit 200 is not always in a working state, or the workload of the filter unit 200 is reduced. Therefore, the embodiment of the present application can also increase the service life of the filter unit 200.

[0050] The following combination Figure 2 and Figure 3 The working process of the vehicle air conditioner is explained.

[0051] See also Figure 2 , when the air quality of the air inside the vehicle does not meet the preset conditions, it means that the air quality inside the vehicle is poor, and the air replenishing mechanism 400 needs to be closed. At this time, the vehicle air conditioner in the embodiment of the present application is the same as the existing vehicle air conditioner: in the external circulation mode, the air outside the vehicle can enter the vehicle air conditioner through the external circulation port in the air intake damper, and then enter the air conditioning box after being filtered and purified by the filter unit 200, and enter the vehicle through the blower 300 after being heated or cooled; in the internal circulation mode, the air inside the vehicle can enter the vehicle air conditioner through the internal circulation port in the air intake damper, and then enter the air conditioning box after being filtered and purified by the filter unit 200, and enter the vehicle through the blower 300 after being heated or cooled.

[0052] See also Figure 3 When the air quality of the air inside the vehicle meets the preset conditions, it means that the air quality inside the vehicle is relatively good. At this time, the air supply mechanism 400 can be turned on, so that the air inside the vehicle enters the air conditioning box of the vehicle air conditioner through the air supply mechanism 400, and the filter unit 200 does not need to filter the air inside the vehicle. In the internal circulation mode, the air inside the vehicle enters the air conditioning box through the air supply mechanism 400, and enters the interior of the vehicle through the blower 300 after being heated or cooled. In the external circulation mode, the air outside the vehicle enters the vehicle air conditioner through the external circulation port in the air intake damper, and then enters the air conditioning box after being filtered and purified by the filter unit 200, and enters the interior of the vehicle through the blower 300 after being heated or cooled.

[0053] See also Figure 4 In some embodiments, the air supply mechanism 400 may include an air supply vent 410 provided on the air conditioning box housing 100, and an air supply damper 420 rotatably connected to the air conditioning box housing 100. When the air supply mechanism 400 is turned on, the air supply damper 420 opens to a certain angle, so that the air inside the vehicle enters the vehicle air conditioner through the air supply vent 410. When the air supply mechanism 400 is not turned on, the air supply damper 420 covers the air supply vent 410 to prevent the air inside the vehicle from entering the vehicle air conditioner.

[0054] For example, see Figure 5, a boss 421 is provided on the inner side of the air supply damper 420, and the boss 421 is embedded in the air supply vent 420 after the air supply damper 420 is closed. For example, the edge of the boss 421 can be rounded, and the edge of the air supply vent 410 is rounded to match the boss 421. During the closing process of the air supply damper 420, the rounded corner setting of the boss 421 and the rounded corner setting of the edge of the air supply vent 410 can play a guiding role, so that the air supply damper 410 can quickly and accurately cover the air supply vent 410, preventing the air inside the vehicle from entering the vehicle air conditioner.

[0055] See also Figure 5 The inner side of the air supply damper 420 is further provided with a convex strip 422 outside the boss 421, and the air conditioner housing 100 is provided with a groove 411 corresponding to the convex strip 422 at the edge of the air supply damper 420. The depth of the groove 411 is inversely proportional to the first distance, and the first distance is the distance from the groove 411 to the rotating shaft, and the rotating shaft is the rotating shaft between the air supply damper 420 and the air conditioner housing 100.

[0056] Specifically, the closer the groove 411 is to the center of the rotating shaft, the deeper it is, and the farther the groove 411 is from the center of the rotating shaft, the shallower it is, so as to ensure that after the air supply damper 420 is closed, the convex strip 422 can be tightly pressed against the groove 411. Exemplarily, a straight line at the bottom of the part of the groove 411 that is perpendicular to the rotating shaft and a plane of the air conditioner housing 100 have a preset angle, for example, the angle can be about 0.5° to 1.5°.

[0057] See also Figure 4 The air supply mechanism 400 may further include a motor 430 and a limiting mechanism 440. The motor 430 is disposed on the air conditioning box housing 100 and connected to the rotating shaft, and is used to control the opening angle of the air supply damper 420. The limiting mechanism 440 is disposed on the air conditioning box housing 100, and is used to limit the maximum opening angle of the air supply damper 420. After the air supply damper 420 opens to a preset angle, the limiting mechanism 440 conflicts with the air supply damper 420. A limiting block 450 corresponding to the limiting mechanism 440 is disposed on the rotating shaft, and the limiting block 450 rotates with the rotating shaft. When the limiting block 450 conflicts with the limiting mechanism 440, the opening angle of the air supply damper 420 reaches the maximum opening angle.

[0058] Exemplarily, one end of the rotating shaft is disposed in the bearing 460, and the other end is connected to the motor 430, and the rotating shaft rotates under the drive of the motor 430. The bearing 460 is fixedly disposed on the air conditioning box housing 100.

[0059] For example, the motor 430 may be a stepper motor or a DC motor, which is not limited thereto.

[0060] In some embodiments, reinforcing ribs may be provided on the outer side of the air supply damper 420 to prevent the air supply damper 420 from deforming so that the air supply damper 420 cannot tightly cover the air supply air port 410, thereby better preventing the air inside the vehicle from entering the vehicle air conditioner when the air supply damper 420 is closed.

[0061] In some embodiments, the air supply mechanism 400 may further include a filter 470 (eg, Figure 5 As shown in the figure, after the air supply damper 420 is opened, the opening faces downward. After the air supply damper 420 is opened, a large object (such as a piece of paper) may enter the vehicle air conditioner along with the air in the vehicle, so the filter 470 can prevent large objects from entering the vehicle air conditioner. Moreover, the air supply damper 420 opens downward, and after a large object is adsorbed on the filter 470, after the blower 300 stops, the large object can fall freely due to gravity, preventing the object from being left on the filter 470.

[0062] Based on the above vehicle air conditioner, the embodiment of the present application also provides a vehicle air conditioner control method for controlling the above vehicle air conditioner. Figure 6 , which shows a flow chart of the implementation of the vehicle air conditioning control method provided by the embodiment of the present application, which is described in detail as follows:

[0063] Step 601, detecting whether the vehicle air conditioner is turned on.

[0064] Step 602: If it is detected that the vehicle air conditioner is turned on, the air quality data of the air inside the vehicle is obtained.

[0065] Exemplarily, the air quality data may include at least one of PM10 data, PM5 data, PM2.5 data, formaldehyde data, nicotine data, etc. For example, after detecting that the vehicle air conditioner is turned on, the air quality data may be obtained through a sensor arranged inside the vehicle.

[0066] Step 603, when the air quality data meets the preset conditions, the air supply mechanism is controlled to open, so that the air inside the vehicle enters the vehicle air conditioner through the air supply mechanism.

[0067] Exemplarily, the above preset condition can be used to characterize that the air quality of the air inside the vehicle is better. For example, the preset condition can be that the air quality data of the air inside the vehicle is less than or equal to the air quality threshold, and the air quality threshold can be set according to actual conditions. Among them, the air quality threshold can include PM10 threshold, PM5 threshold, PM2.5 threshold, formaldehyde threshold, nicotine threshold, etc.

[0068] In one scenario, the air quality threshold is set before the vehicle leaves the factory. In another scenario, after the vehicle leaves the factory, the user can set the air quality threshold, or adjust the air quality threshold set before leaving the factory.

[0069] In the embodiment of the present application, when the air quality data inside the vehicle meets the preset conditions, the air supply mechanism can be turned on so that the air inside the vehicle enters the vehicle air conditioner through the air supply mechanism without filtering the air inside the vehicle through the filter unit. After impurities such as dust or particles are attached to the filter unit, the flow resistance of the air flowing through the filter unit will be greatly increased, thereby resulting in a reduction in the air flow rate of the filter unit, which reduces the performance of the vehicle air conditioner and causes the performance of the vehicle air conditioner to be not fully utilized. Since the embodiment of the present application does not need to pass through the filter unit when the air supply mechanism is in the turned-on state, the air inside the vehicle enters the vehicle air conditioner without passing through the filter unit, and therefore the air flow rate will not be reduced due to the above-mentioned flow resistance, thereby improving the performance of the vehicle air conditioner and making more full use of the performance of the vehicle air conditioner.

[0070] In addition, since the air supply mechanism is arranged between the filter unit and the blower, the air enters the vehicle air conditioner through the air supply mechanism and does not pass through the filter unit, so that the filter unit is not always in working state, or the workload of the filter unit is reduced, so the embodiment of the present application can also increase the service life of the filter unit. Moreover, it can also reduce the flow resistance at the front end of the blower, improve the energy efficiency of the blower, save the power consumption of the whole vehicle, and improve the NVH perception of the whole vehicle.

[0071] In some possible implementations, step 603 may include: if the air quality data meets preset conditions, obtaining glass fogging determination data; based on the above glass fogging determination data, determining whether there is a risk of fogging on the front windshield of the vehicle; if there is no risk of fogging, controlling the air replenishment mechanism to open.

[0072] Generally, the humidity of the air outside the vehicle is lower than the humidity of the air inside the vehicle. Therefore, when the air quality of the air inside the vehicle meets the preset conditions, it is also necessary to determine the fogging risk of the vehicle's front windshield. If the fogging risk is low (for example, the calculated fogging risk value is less than the fogging risk threshold), the air supply mechanism can be controlled to open so that the air inside the vehicle enters the vehicle air conditioner through the air supply mechanism. If the fogging risk is high (for example, the calculated fogging risk value is greater than or equal to the fogging risk threshold), the air supply mechanism can be controlled not to open so that the drier air outside the vehicle enters the vehicle air conditioner to reduce the fogging risk of the front windshield.

[0073] In some embodiments, the glass fogging determination data may include: a first temperature of the front windshield, a first humidity inside the vehicle, and a second temperature inside the vehicle.

[0074] Exemplarily, determining whether there is a risk of fogging for the front windshield of a vehicle may include: obtaining a first temperature of the front windshield, a first humidity inside the vehicle, and a second temperature inside the vehicle; and determining whether there is a risk of fogging for the front windshield based on the first temperature, the first humidity, and the second temperature.

[0075] For example, the current dew point temperature is calculated according to the first humidity and the second temperature, and then the difference Δt between the current dew point temperature and the first temperature is calculated. It is determined whether there is a risk of fogging of the front windshield according to the difference Δt, the first set temperature T1 and the second set temperature T2. The first set temperature and the second set temperature are constants and can be obtained through experiments.

[0076] For example, the fogging risk of the front windshield can be preliminarily judged based on the positions of Δt and T1 and T2. If Δt is less than T1, the inner surface of the front windshield will not fog; if Δt is greater than T1 and less than T2, there is a risk of fogging on the inner surface of the front windshield; if Δt is greater than T2, the inner surface of the front windshield will be completely fogged.

[0077] In some possible implementations, controlling the opening of the air supply mechanism in step 603 may include: determining the opening angle of the air supply mechanism based on at least one of the vehicle air-conditioning panel temperature, the vehicle interior temperature, the vehicle exterior temperature, the vehicle air-conditioning evaporator temperature, and the sunlight illumination inside the vehicle; and controlling the opening of the air supply mechanism based on the above-mentioned opening angle.

[0078] After determining that there is no risk of fogging on the front windshield of the vehicle, the air supply mechanism can be controlled to open. In order to more efficiently heat or cool the interior of the vehicle and make the user feel more comfortable, this can be achieved by controlling the opening angle of the air supply mechanism.

[0079] For example, when the temperature inside the vehicle is more conducive to the heating or cooling function of the air conditioner than the temperature outside the vehicle, the air supply mechanism can be controlled to open a larger angle to use more air inside the vehicle to achieve the heating or cooling function of the air conditioner. When the temperature inside the vehicle is not conducive to the heating or cooling function of the air conditioner than the temperature outside the vehicle, the air supply mechanism can be controlled to open a smaller angle to use more air outside the vehicle to achieve the heating or cooling function of the air conditioner.

[0080] Exemplarily, the vehicle air conditioning panel temperature may include a panel setting temperature and a panel target comfort temperature, and the opening angle is proportional to the difference between the panel setting temperature and the panel target comfort temperature.

[0081] The panel target comfort temperature can be a range, which is usually related to factors such as seasons and personal habits. For example, in winter, the panel target comfort temperature can be above 24°C, and in summer, the panel target comfort temperature can be 22°C to 26°C. If the difference between the panel set temperature and the panel target comfort temperature is large, it means that the temperature set by the user is very different from the panel target comfort temperature. The user may feel uncomfortable at the panel set temperature and needs to increase the opening angle to allow more air in the car to flow to the evaporator. The evaporator adjusts the temperature of the air in the car to the panel target comfort temperature to increase the user's comfort.

[0082] For example, when the air conditioner turns on the cooling function, the panel setting temperature is 16°C, which is quite different from the panel target comfort temperature (22°C to 26°C). At this panel setting temperature, the user will feel uncomfortable, so the opening angle can be widened to allow more air in the car to flow to the evaporator. After that, the evaporator adjusts the temperature of the air in the car flowing to the evaporator to the panel target comfort temperature, and then discharges it into the vehicle to increase the user's comfort. As the difference between the panel setting temperature and the panel target comfort temperature becomes smaller, the opening angle of the air replenishment mechanism can be reduced.

[0083] Exemplarily, the above-mentioned vehicle interior temperature may include an actual vehicle interior temperature and a target vehicle interior temperature, and the opening angle is proportional to the difference between the actual vehicle interior temperature and the target vehicle interior temperature.

[0084] The target temperature inside the vehicle can be a range, which is usually related to factors such as seasons and personal habits. For example, the target temperature inside the vehicle can be 18°C ​​to 24°C in winter and 24°C to 28°C in summer. If the difference between the actual temperature inside the vehicle and the target temperature inside the vehicle is large, the user's comfort is poor, and it is necessary to control the air supply mechanism to open a larger angle and use more air inside the vehicle to achieve the heating or cooling function of the air conditioner.

[0085] For example, in the cooling function, the actual temperature inside the vehicle is 30°C and the target temperature inside the vehicle is 24°C. Since the difference between the actual temperature inside the vehicle and the target temperature inside the vehicle is large, the air supply mechanism can be controlled to open at a larger angle, using more air inside the vehicle to achieve the cooling function of the air conditioner, so that the temperature inside the vehicle can drop to near the target temperature inside the vehicle as soon as possible. As the difference between the actual temperature inside the vehicle and the target temperature inside the vehicle becomes smaller, the opening angle of the air supply mechanism can be adjusted to a smaller angle.

[0086] Exemplarily, the vehicle exterior temperature may include an actual vehicle exterior temperature and a target vehicle exterior temperature, and the opening angle is proportional to a difference between the actual vehicle exterior temperature and the target vehicle exterior temperature.

[0087] The target temperature outside the vehicle can be within a certain range, which is usually related to factors such as seasons and personal habits. For example, the target temperature outside the vehicle can be -5°C to 5°C in winter, and can be 26°C to 32°C in summer. If the difference between the actual temperature outside the vehicle and the target temperature outside the vehicle is large, it is necessary to control the air supply mechanism to open at a larger angle, so that more air inside the vehicle can be used to achieve the heating or cooling function of the air conditioner.

[0088] For example, in the cooling function, the actual temperature outside the vehicle is 36°C and the target temperature outside the vehicle is 31°C. Since the difference between the actual temperature outside the vehicle and the target temperature outside the vehicle is large, the air temperature outside the vehicle is high. At this time, the air supply mechanism can be controlled to open at a larger angle, so that more air inside the vehicle can be used to achieve the cooling function of the air conditioner and reduce the power consumption of the air conditioner. As the difference between the actual temperature outside the vehicle and the target temperature outside the vehicle becomes smaller, the opening angle of the air supply mechanism can be adjusted to a smaller angle.

[0089] Exemplarily, the evaporator temperature may include an actual evaporator temperature and a target evaporator temperature, and the opening angle is proportional to the difference between the actual evaporator temperature and the target evaporator temperature.

[0090] Among them, the evaporator target temperature can be calculated based on the air conditioning comfort algorithm to improve the comfort of users in the car. For example, under the cooling function, the actual temperature of the vehicle evaporator is 21°C, and the target temperature of the vehicle evaporator is 26°C. At this time, the wind blown out by the air conditioner feels colder and the user's comfort is poor. The air replenishment mechanism can be controlled to open a larger angle to allow more air in the car to flow to the evaporator. After that, the evaporator adjusts the temperature of the air in the car flowing to the evaporator to the vehicle evaporator target temperature, and then discharges it into the vehicle to increase the user's comfort. As the difference between the actual evaporator temperature and the evaporator target temperature becomes smaller, the opening angle of the air replenishment mechanism can be reduced.

[0091] Exemplarily, the above-mentioned sunlight illuminance may include current sunlight illuminance and a sunlight illuminance target value. When the vehicle air conditioner turns on the cooling function, the opening angle is directly proportional to the difference between the current sunlight illuminance and the sunlight illuminance target value; when the vehicle air conditioner turns on the heating function, the opening angle is inversely proportional to the difference between the current sunlight illuminance and the sunlight illuminance target value.

[0092] Among them, the sunlight illumination target value can be an interval range, which is usually related to factors such as season and personal habits. When the air conditioner turns on the cooling function, if the difference between the current sunlight illumination and the sunlight illumination target value is large, it means that the temperature outside the vehicle is higher than the temperature inside the vehicle. At this time, the air supply mechanism can be controlled to open a larger angle, and the air inside the vehicle can be used more to realize the cooling function of the air conditioner, and the temperature inside the vehicle can be reduced to a temperature that the user feels comfortable as soon as possible. When the air conditioner turns on the heating function, if the difference between the current sunlight illumination and the sunlight illumination target value is large, it means that the temperature outside the vehicle is higher than the temperature inside the vehicle. At this time, the air supply mechanism can be controlled to open a smaller angle, and the air outside the vehicle can be used more to realize the heating function of the air conditioner, and the temperature inside the vehicle can be adjusted to a temperature that the user feels comfortable as soon as possible.

[0093] For example, the above-mentioned determination of the opening angle of the air supply mechanism may include:

[0094] ASDOpen=a*|PanelTempSet-ComfortTemp|+b*|AmbTemp-ComfortAmbTemp|+c*|InCarTempSet-InCarTempAct|+d*(SunAct-SunAmbtarget)+e*(EvpSet-EvpAct)+f

[0095] Determine the opening angle of the air supply mechanism. Among them, ASDOpen represents the opening angle, PanelTempSet represents the panel set temperature, ComfortTemp represents the panel target comfort temperature, AmbTemp represents the actual temperature outside the vehicle, ComfortAmbTemp represents the target temperature outside the vehicle, InCarTempSet represents the actual temperature inside the vehicle, InCarTempAct represents the target temperature inside the vehicle, SunAct represents the current sunlight illumination, SunAmbtarget represents the target sunlight illumination value, EvpSet represents the evaporator target temperature, EvpAct represents the actual evaporator temperature, a, b, c, d and e are compensation coefficients, and f is a preset calibration value.

[0096] For example, the range of PanelTempSet is 16°C to 32°C, with an accuracy of 0.5°C. InCarTempSet and EvpSet can be calculated by the air conditioning comfort algorithm. For different vehicle external temperatures, SunAmbtarget can correspond to different values.

[0097] The cooling and heating requirements corresponding to the air conditioning panel temperature setting are calculated by |PanelTempSet-ComfortTemp|. The larger the PanelTempSet is from ComfortTemp, the greater the opening angle requirement of the air supply damper is, and it is compensated by the coefficient a.

[0098] The deviation of the actual temperature outside the vehicle from the human comfort temperature is calculated through |AmbTemp-ComfortAmbTemp|. The colder or hotter it is, the greater the opening angle of the air supply damper is required, and it is compensated by the coefficient b.

[0099] InCarTempSet is the target temperature inside the vehicle that is more comfortable for the human body, calculated by the air conditioning comfort algorithm. The deviation between the target temperature inside the vehicle and the actual temperature inside the vehicle is calculated by |InCarTempSet-InCarTempAct|. The greater the deviation, the greater the opening angle required for the air supply damper, which is compensated by the coefficient c.

[0100] (SunAct-SunAmbtarget) is the impact of sunlight on the air damper. In summer, the stronger the sunlight, the larger the opening angle of the air damper, and the weaker the sunlight, the smaller the opening angle of the air damper. In winter, the stronger the sunlight, the smaller the opening angle of the air damper, and the weaker the sunlight, the larger the opening angle of the air damper, and compensation is made by the coefficient d.

[0101] The deviation between the actual evaporator temperature and the target evaporator temperature is calculated by (EvpSet-EvpAct). The larger the deviation is, the greater the opening angle of the air supply damper is required, and it is compensated by the coefficient e.

[0102] Among them, ComfortTemp, ComfortAmbTemp, InCarTempSet, SunAmbtarget, EvpSet, a, b, c, d, e, and f are all calibration values. During the comfort calibration and verification stage, the internal flow field, external flow field, etc. of each vehicle are calibrated to maximize the performance of the air conditioner and meet the comfort requirements of the air conditioner.

[0103] In some possible implementations, the method may further include: controlling the internal circulation damper of the vehicle air conditioner to close, and adjusting the vehicle air conditioner to an external circulation mode. In order to prevent dust and other objects on the filter element of the filter unit from entering the air conditioner box through the air supply damper after the air supply damper is opened, when the air supply damper is opened, the internal circulation damper may be closed, and the internal circulation damper may be adjusted to an external circulation mode, thereby preventing dust and other objects on the filter element of the filter unit from entering the air conditioner box through the air supply damper.

[0104] For example, the above-mentioned control of closing the inner circulation damper of the vehicle air conditioner to adjust the vehicle air conditioner to the outer circulation mode may be performed while the air supply mechanism is controlled to be turned on in step 603. Alternatively, the above-mentioned control of closing the inner circulation damper of the vehicle air conditioner to adjust the vehicle air conditioner to the outer circulation mode may be performed after the air supply mechanism is controlled to be turned on in step 603. Alternatively, the above-mentioned control of closing the inner circulation damper of the vehicle air conditioner to adjust the vehicle air conditioner to the outer circulation mode may be performed after determining that the air quality of the air inside the vehicle meets the preset condition and before the air supply mechanism is controlled to be turned on in step 603, and the inner circulation damper of the vehicle air conditioner to adjust the vehicle air conditioner to the outer circulation mode may be performed.

[0105] Figure 7 The following is a flowchart of the vehicle air conditioning control method according to the embodiment of the present application, which is described in detail as follows:

[0106] Step 701, vehicle status detection.

[0107] For example, checking whether the various components of the vehicle can operate normally.

[0108] Step 702, detect whether the vehicle is powered on and whether the air conditioner is running.

[0109] If the air conditioner is running, execute step 703; if the air conditioner is not running, execute step 706.

[0110] Step 703, start the air supply mechanism to detect and determine.

[0113] If the air quality inside the vehicle is good, execute step 707; otherwise, execute step 706.

[0114] Step 706, controlling the air supply damper to close, and returning to step 701.

[0115] For example, if the air supply damper is in the open state, the air supply damper is controlled to be closed; if the air supply damper is in the closed state, the air supply damper does not need to perform any action and continues to remain in the closed state.

[0116] Step 707 , determining the fogging risk of the front windshield based on the first temperature and the first humidity of the front windshield and the second temperature inside the vehicle.

[0118] Step 709, determining the opening angle of the air supply damper according to the vehicle air conditioning panel temperature, the vehicle interior temperature, the vehicle exterior temperature, the vehicle air conditioning evaporator temperature and the sunlight illumination inside the vehicle.

[0119] Step 710, controlling the internal circulation damper of the vehicle air conditioner to close, adjusting the vehicle air conditioner to the external circulation mode, and controlling the air supply damper to open according to the determined opening angle.

[0120] 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 the present application.

[0121] The following is an embodiment of the device of the present application. For details not described in detail, please refer to the corresponding method embodiment described above.

[0122] Figure 8 The structural diagram of the vehicle air conditioning control device provided by the embodiment of the present application is shown. For the convenience of explanation, only the parts related to the embodiment of the present application are shown, which are described in detail as follows:

[0123] like Figure 8 As shown, the vehicle air conditioning control device 800 may include a detection module 801, an acquisition module 802 and a control module 803. Among them, the detection module 801 is used to detect whether the vehicle air conditioning is turned on. The acquisition module 802 is used to obtain the air quality data of the air inside the vehicle after the detection module 801 detects that the vehicle air conditioning is turned on. The control module 803 is used to control the air supply mechanism to turn on when the air quality data meets the preset conditions, so that the air inside the vehicle enters the vehicle air conditioning through the air supply mechanism.

[0124] In traditional vehicle air conditioners, the air entering the vehicle air conditioner needs to pass through the filter unit before entering the air conditioning box. After impurities such as dust or particles adhere to the filter unit, the flow resistance of the air flowing through the filter unit will be greatly increased, resulting in a decrease in the air flow rate of the filter unit, which reduces the performance of the vehicle air conditioner and causes the performance of the vehicle air conditioner to not be fully utilized.

[0125] In the embodiment of the present application, when the air quality data inside the vehicle meets the preset conditions, the air supply mechanism can be turned on so that the air inside the vehicle enters the vehicle air conditioner through the air supply mechanism without filtering the air inside the vehicle through the filter unit. After impurities such as dust or particles are attached to the filter unit, the flow resistance of the air flowing through the filter unit will be greatly increased, thereby resulting in a reduction in the air flow rate of the filter unit, which reduces the performance of the vehicle air conditioner and causes the performance of the vehicle air conditioner to be not fully utilized. Since the embodiment of the present application does not need to pass through the filter unit when the air supply mechanism is in the turned-on state, the air inside the vehicle enters the vehicle air conditioner without passing through the filter unit, and therefore the air flow rate will not be reduced due to the above-mentioned flow resistance, thereby improving the performance of the vehicle air conditioner and making more full use of the performance of the vehicle air conditioner.

[0126] In addition, since the air supply mechanism is disposed between the filter unit and the blower, the air enters the vehicle air conditioner through the air supply mechanism and does not pass through the filter unit, so that the filter unit is not always in a working state, or the workload of the filter unit is reduced, so the embodiment of the present application can also increase the service life of the filter unit. Moreover, the embodiment of the present application can also reduce the flow resistance at the front end of the blower, improve the energy efficiency of the blower, save the power consumption of the whole vehicle, and improve the NVH perception of the whole vehicle.

[0127] In one possible implementation, the control module 803 is specifically used to: if the air quality data meets the preset conditions, obtain glass fogging judgment data; based on the above glass fogging judgment data, determine whether there is a fogging risk on the front windshield of the vehicle; if there is a fogging risk, control the air replenishment mechanism to open.

[0128] In one possible implementation, the control module 803 controls the opening of the air supply mechanism, including: determining the opening angle of the air supply mechanism according to at least one of the vehicle air-conditioning panel temperature, the vehicle interior temperature, the vehicle exterior temperature, the vehicle air-conditioning evaporator temperature, and the sunlight illumination inside the vehicle; and controlling the opening of the air supply mechanism based on the opening angle.

[0129] Exemplarily, the vehicle air conditioning panel temperature may include a panel setting temperature and a panel target comfort temperature, and the opening angle is proportional to the difference between the panel setting temperature and the panel target comfort temperature.

[0130] Exemplarily, the vehicle interior temperature may include an actual vehicle interior temperature and a target vehicle interior temperature, and the opening angle is proportional to a difference between the actual vehicle interior temperature and the target vehicle interior temperature.

[0131] Exemplarily, the vehicle external temperature may include an actual vehicle external temperature and a vehicle external target temperature, and the opening angle is proportional to the difference between the actual vehicle external temperature and the vehicle external target temperature.

[0132] Exemplarily, the evaporator temperature may include an actual evaporator temperature and a target evaporator temperature, and the opening angle is proportional to the difference between the actual evaporator temperature and the target evaporator temperature.

[0133] Exemplarily, the sunlight illuminance may include the current sunlight illuminance and the sunlight illuminance target value. When the vehicle air conditioner turns on the cooling function, the opening angle is directly proportional to the difference between the current sunlight illuminance and the sunlight illuminance target value; when the vehicle air conditioner turns on the heating function, the opening angle is inversely proportional to the difference between the current sunlight illuminance and the sunlight illuminance target value.

[0134] In a possible implementation, the above determination of the opening angle of the air supply mechanism includes: ASDOpen = a*|PanelTempSet-ComfortTemp|+b*|AmbTemp-ComfortAmbTemp|+c*|InCarTempSet-InCarTempAct|+d*(SunAct-SunAmbtarget)+e*(EvpSet-EvpAct)+f

[0135] Determine the opening angle of the air supply mechanism. Wherein, ASDOpen represents the opening angle, PanelTempSet represents the panel set temperature, ComfortTemp represents the panel target comfort temperature, AmbTemp represents the actual temperature outside the vehicle, ComfortAmbTemp represents the target temperature outside the vehicle, InCarTempSet represents the actual temperature inside the vehicle, InCarTempAct represents the target temperature inside the vehicle, SunAct represents the current sunlight illumination, SunAmbtarget represents the target sunlight illumination value, EvpSet represents the evaporator target temperature, EvpAct represents the actual evaporator temperature, a, b, c, d and e are compensation coefficients, and f is a preset calibration value.

[0136] In a possible implementation, the control module 803 may also be used to: control the internal circulation damper of the vehicle air conditioner to close, and adjust the vehicle air conditioner to the external circulation mode.
