[0024] In order to make the purpose, technical solutions 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 intended to limit the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work are protected by the present application.

[0025] With the rapid development of automobile industry technology, there are more and more glass parts on cars, and the area occupied by glass is getting larger and larger. In the hot summer, solar heat radiation penetrates the car glass, causing the temperature inside the car to rise sharply, resulting in the need for higher cooling capacity of the car air conditioner to maintain the comfort of the passenger compartment. However, higher cooling performance often leads to higher power consumption, affecting the vehicle's range.

[0026] In view of this, the present application proposes a control method for an air curtain, which can cover the vehicle window glass with the air curtain, reduce solar heat radiation, block heat exchange between the interior environment of the vehicle and the hot air outside the vehicle, reduce the power required for the vehicle air conditioner, and make the air volume of the air curtain adapt to the solar lighting conditions, thereby reducing vehicle energy consumption and increasing vehicle range.

[0027] In order to illustrate the technical solution of the present application, a specific embodiment is provided below for illustration.

[0028] Figure 1 The present invention provides a schematic diagram of the implementation process of an air curtain control method provided in an embodiment of the present invention, which can be applied to a vehicle. The above-mentioned vehicle can refer to a hybrid vehicle, a pure electric vehicle, a fuel vehicle or other types of vehicles, which is not limited in the present invention.

[0029] In an embodiment of the present application, the above-mentioned vehicle may be configured with an air curtain, and the air curtain may be used to cover the vehicle window glass.

[0030] Specifically, an air curtain is an "air wall" formed by high-speed airflow. Figure 2 As shown, taking the air curtain covering the window glass as an example, the door panel can be provided with an air duct, and the cold air flow is ejected through the small holes at the tip, and the air flow is amplified to cover the entire window glass. The air flow of the air curtain is low-temperature air, which covers the window glass to isolate the air circulation between the passenger compartment and the outside environment, thereby preventing the exchange of temperature and humidity between the passenger compartment and the outside environment.

[0031] In some embodiments of the present application, the air curtain can work in conjunction with the air conditioning system to evenly distribute cold air to every corner of the room to improve indoor air flow, increase cooling efficiency, and enhance comfort. Figure 3 As shown, taking the air curtain covering the car window glass as an example, when the airflow reaches the upper door frame, it can flow toward the passenger compartment along the vertical direction of the car window to participate in the airflow circulation in the passenger compartment.

[0032] It should be noted that the air curtain in the embodiments of the present application may include but is not limited to: an air curtain located at the front wind window position, an air curtain located at the left window position, an air curtain located at the right window position, an air curtain located at the rear wind window position, and an air curtain located at the skylight, and the present application does not impose any restrictions on this.

[0033] Specifically, the air curtain control method may include the following steps S101 to S103.

[0034] Step S101, obtaining the window glass temperature.

[0035] In the embodiment of the present application, when the air conditioning system of the vehicle is turned on, the window glass temperature Tglass can be monitored. The window glass temperature Tglass is the temperature on the window glass, which can be measured by a sensor arranged near the window. The window glass temperature Tglass can reflect the temperature of the environment outside the vehicle.

[0036] Step S102, when the window glass temperature is greater than or equal to a first glass temperature threshold, control the air curtain of the vehicle to open.

[0037] Among them, the first glass temperature threshold is used to determine whether there is a significant temperature difference between the inside and outside of the vehicle, and can be set according to actual conditions.

[0038] In the implementation of the present application, when the window glass temperature is less than the first glass temperature threshold, the air curtain does not need to be activated because the temperature inside the vehicle is generally not lower than this temperature. For example, when the window glass temperature Tglass is less than 26°C, the air curtain is not activated. When the window glass temperature is greater than or equal to the first glass temperature threshold, the passenger compartment may heat up due to heat exchange with the outside environment, and the vehicle's air curtain may be controlled to open.

[0039] Step S103, controlling the air volume ratio of the air curtain according to the sunlight information.

[0040] In the implementation of the present application, the sunlight information may indicate the position of the sun relative to the vehicle. According to the sunlight information, the air volume ratio of the air curtain is controlled. The air volume ratio represents the ratio of the air volume of the air curtain at different positions to the total air volume of all air curtains. The higher the air volume ratio, the higher the wind force of the air curtain airflow, which can play a stronger barrier role to the environment inside and outside the vehicle.

[0041] In an embodiment of the present application, by acquiring the temperature of the vehicle window glass, when the temperature of the vehicle window glass is greater than or equal to the first glass temperature threshold, the air curtain of the vehicle that covers the vehicle window glass is controlled to open, and according to the sunlight information, the air volume ratio of the air curtain is controlled. On the one hand, by covering the vehicle window glass with the air curtain, solar heat radiation can be weakened, and heat exchange between the interior environment of the vehicle and the hot air outside the vehicle can be blocked, thereby reducing the power required for the vehicle air conditioner and reducing the energy consumption of the vehicle. On the other hand, according to the sunlight information, the air volume ratio of the air curtain is controlled, so that the air volume of the air curtain can be adapted to the sunlight conditions to avoid the problem of heating up the passenger compartment due to too low air volume, thereby reducing the energy consumption of the vehicle and helping to increase the vehicle's cruising range.

[0042] In some embodiments of the present application, Figure 4 As shown, controlling the opening of the air curtain of the vehicle may include: step S401 to step S402.

[0043] Step S401, obtaining a first vehicle interior temperature.

[0044] The first vehicle interior temperature refers to the temperature in the passenger compartment when the air curtain of the vehicle is about to be started, and may refer to the average temperature in the passenger compartment. The first vehicle interior temperature may be detected by a temperature sensor in the passenger compartment.

[0045] Step S402: Control the air curtain to open according to the corresponding air curtain gear position according to the first vehicle interior temperature.

[0046] In the embodiment of the present application, the air curtain may be provided with different air curtain gears. The air flow velocity and / or air flow temperature are different between different air curtain gears. The higher the gear, the higher the air flow velocity and / or lower the air flow temperature of the air curtain.

[0047] The first in-car temperature can reflect the temperature condition in the passenger compartment, and according to the first in-car temperature, the air curtain can be controlled to open according to a corresponding air curtain gear position.

[0048] Specifically, Figure 5 As shown, according to the first in-vehicle temperature, controlling the air curtain to open according to the corresponding air curtain gear position may include: step S501 to step S502.

[0049] Step S501: If the first in-vehicle temperature is lower than the first in-vehicle temperature threshold, the air curtain is controlled to open according to the first air curtain gear.

[0050] Step S502, if the first in-car temperature is greater than or equal to the first in-car temperature threshold, the air curtain is controlled to open according to the second air curtain gear, and the vehicle air conditioner is controlled to turn on until the vehicle's in-car temperature is less than the first in-car temperature threshold, then the vehicle air conditioner is turned off and the gear of the air curtain is adjusted to the first air curtain gear.

[0051] Among them, the second air curtain gear is higher than the first air curtain gear.

[0052] The first vehicle interior temperature threshold is used to determine whether the temperature in the passenger compartment is suitable. If the first vehicle interior temperature is less than the first vehicle interior temperature threshold, indicating that the temperature in the passenger compartment is suitable, the air curtain can be controlled to open according to the first lower air curtain gear to block heat exchange between the inside and outside of the vehicle.

[0053] If the first in-car temperature is greater than or equal to the first in-car temperature threshold, it means that the temperature in the passenger compartment is too high. On the one hand, the air curtain needs to be controlled to open according to the higher second air curtain gear to block the heat exchange between the inside and outside of the vehicle while providing a higher cooling effect. At the same time, the vehicle air conditioner needs to be controlled to open so that the passenger compartment can be restored to a suitable temperature as soon as possible. As the in-car temperature decreases, when the vehicle's in-car temperature is less than the first in-car temperature threshold, the vehicle air conditioner can be turned off and the air curtain gear can be adjusted to the first air curtain gear, which can maintain a suitable temperature in the passenger compartment and reduce the high power consumption caused by the high-power operation of the vehicle air conditioner and air curtain.

[0054] In some embodiments of the present application, controlling the vehicle air conditioner to turn on may include: controlling the vehicle air conditioner to turn on according to a corresponding air conditioning gear according to the first in-vehicle temperature.

[0055] Among them, the cooling capacity of the air-conditioning gear is proportional to the first vehicle interior temperature.

[0056] Specifically, when the first in-car temperature is less than or equal to the second in-car temperature threshold, the in-car air conditioner can be controlled to turn on according to the first air conditioner gear. When the first in-car temperature is greater than the second in-car temperature threshold, the in-car air conditioner can be controlled to turn on according to the second air conditioner gear.

[0057] Among them, the cooling capacity of the second air-conditioning gear is higher than the cooling capacity of the first air-conditioning gear, so that the passenger compartment can be restored to a suitable temperature more quickly.

[0058] In some embodiments of the present application, after controlling the vehicle air conditioner to turn on, the method may further include: obtaining a second vehicle interior temperature after the vehicle air conditioner is turned on for a preset time. If the second vehicle interior temperature is not lower than the first vehicle interior temperature, the gear of the air conditioner is increased.

[0059] The preset time can be set according to actual needs, for example, 10 minutes, 15 minutes, etc. After the air conditioner is turned on for the preset time, the temperature in the passenger compartment is re-detected to obtain a second vehicle interior temperature. If the second vehicle interior temperature is not lower than the first vehicle interior temperature, it means that the current cooling capacity is insufficient, and the gear of the air conditioner needs to be increased to improve the cooling capacity of the air conditioner.

[0060] If the second in-car temperature is lower than the first in-car temperature, the air conditioner gear can be lowered. After the vehicle's in-car temperature is lower than the first in-car temperature threshold, the vehicle air conditioner can be turned off and the air curtain gear can be adjusted to the first air curtain gear.

[0061] It is understandable that by gradually lowering the gears of the air curtain and the car air conditioner, or even turning off the car air conditioner according to the real-time temperature conditions in the car, the vehicle's energy consumption can be effectively reduced and the vehicle's cruising range can be increased.

[0062] In some embodiments of the present application, the air curtain gear position when the air curtain is turned on may be positively correlated with the window glass temperature. That is, if the window glass temperature is higher, the air curtain gear position when the air curtain is turned on may be set higher to achieve a higher cooling effect and airflow blocking effect.

[0063] Similarly, the air conditioner gear when the air conditioner is turned on may be positively correlated with the window glass temperature. That is, if the window glass temperature is higher, the air conditioner gear when the air conditioner is turned on may be set higher to achieve a higher cooling effect.

[0064] The following example illustrates this:

[0065] Case 1: When the window glass temperature is 26℃≤Tglass≤30℃:

[0066] If the first in-car temperature Tcabin is less than the first in-car temperature threshold of 24°C, strategy ① is executed: the air curtain system is turned on and adjusted to the first gear, and the vehicle air conditioner is not turned on.

[0067] If the first in-car temperature threshold 24℃≤the first in-car temperature Tcabin≤the second in-car temperature threshold 30℃, then execute strategy ②: turn on the air curtain and adjust it to the second gear (higher than the first gear), and turn on the car air conditioner and adjust it to the third gear; after the preset time of 10 minutes, continue to monitor the in-car temperature to obtain the second in-car temperature Tcabin. If the second in-car temperature Tcabin drops below the first in-car temperature threshold 24℃, then execute strategy ①. If the temperature is maintained at 24-30℃, keep the air curtain gear unchanged, increase the air conditioner gear to the fifth gear, continue to monitor the in-car temperature Tcabin and adjust to the corresponding strategy. If the second in-car temperature Tcabin rises by more than 30℃, then execute strategy ③.

[0068] If the first car interior temperature Tcabin is greater than 30°C, strategy ③ is executed: turn on the air curtain and adjust it to the second gear, and at the same time turn on the car air conditioner and adjust it to the fifth gear; after the preset time of 10 minutes, continue to monitor the car interior temperature to obtain the second car interior temperature Tcabin. If the second car interior temperature Tcabin drops below the first car interior temperature threshold of 24°C, strategy ① is executed. If the second car interior temperature Tcabin drops to between 24 and 30°C, strategy ② is executed. If the temperature continues to remain above 30°C, the air curtain gear remains unchanged, the air conditioning gear is increased to the seventh gear, and the car interior temperature Tcabin is continuously monitored and adjusted to the corresponding strategy.

[0069] Case 2: When the window glass temperature Tglass>30℃:

[0070] If the first vehicle interior temperature Tcabin is less than the first vehicle interior temperature threshold of 24°C, then execute strategy ④: turn on the air curtain system and adjust it to the second gear, and do not turn on the vehicle air conditioner. It can be understood that the window glass temperature in situation 2 is higher than that in situation 1. Similarly, when the first vehicle interior temperature Tcabin is less than the first vehicle interior temperature threshold of 24°C, strategy ④ needs to use a higher air curtain gear than strategy 1.

[0071] If the first vehicle interior temperature threshold 24℃≤the first vehicle interior temperature Tcabin≤the second vehicle interior temperature threshold 30℃, then execute strategy ⑤: turn on the air curtain and adjust it to the third gear, and turn on the vehicle air conditioner and adjust it to the fifth gear; after the preset time of 15 minutes, continue to monitor the second vehicle interior temperature Tcabin. If the second vehicle interior temperature Tcabin drops below the first vehicle interior temperature threshold 24℃, then execute strategy ④. If the second vehicle interior temperature Tcabin is maintained between 24 and 30℃, keep the air curtain gear unchanged, increase the air conditioner gear to the fifth gear, continue to monitor the vehicle interior temperature Tcabin and adjust it to the corresponding strategy. If the second vehicle interior temperature Tcabin rises by more than 30℃, then execute strategy ⑥. It can be understood that the window glass temperature in situation 2 is higher than that in situation 1. Similarly, when the first vehicle interior temperature threshold 24℃≤the first vehicle interior temperature Tcabin≤the second vehicle interior temperature threshold 30℃, strategy ⑤ needs to use a higher air curtain gear and air conditioner gear than strategy ②.

[0072] If the first car interior temperature Tcabin>30℃, then execute strategy ⑥: turn on the air curtain, adjust to the third gear, and turn on the car air conditioner at the same time, adjust to the seventh gear; after the preset time of 15 minutes, continue to monitor the second car interior temperature Tcabin, if the second car interior temperature Tcabin drops below the first car interior temperature threshold of 24℃, then execute strategy ④, if the second car interior temperature Tcabin drops to between 24 and 30℃, then execute strategy ⑤, if the second car interior temperature Tcabin continues to maintain above 30℃, then keep the air curtain gear unchanged, if the air conditioning gear can continue to increase, then increase the air conditioning gear, if the air conditioning gear is up to the seventh gear, then keep the air conditioning gear unchanged, continue to monitor the car interior temperature Tcabin and adjust to the corresponding strategy. Similarly, compared with the case 2, the window glass temperature is higher than that of the case 1. Similarly, when the first car interior temperature Tcabin>30℃, the air curtain gear and air conditioning gear used in strategy ⑥ need to be higher than those used in strategy ③.

[0073] In the implementation mode of the present application, the air curtain and the gear position of the air conditioner can be controlled according to the actual driving conditions to block the solar heat radiation through the glass and reduce the heat load in the car, so that the car air conditioner does not need to be in a high-power operation state for a long time, which helps to improve driving comfort and power economy.

[0074] In an implementation manner of the present application, after the air curtain is turned on, the air volume ratio of the air curtain can be controlled according to the sunlight information.

[0075] Specifically, in some embodiments of the present application, the sunlight information may include the ratio of the area of ​​each vehicle window illuminated by the sun to the total vehicle window area; and controlling the air volume ratio of the air curtain according to the sunlight information may include: determining the air volume ratio of the air curtain at each vehicle window position according to the ratio. The air volume ratio is positively correlated with the ratio.

[0076] Specifically, for each car window, the ratio of the sun-irradiated area to the total window area can be calculated to analyze the direction of sunlight. The larger the ratio of the sun-irradiated area to the total window area, the more the window faces the sun, and the larger the air volume ratio of the air curtain at the window position should be. In this way, for windows with a larger area exposed to the sun, the air curtain used to cover the window glass will operate at a higher air volume ratio, thereby reducing high-intensity solar radiation. For windows that are not exposed to the sun, the air curtain used to cover the window glass will operate at a lower air volume ratio, thereby reducing power consumption.

[0077] For example, the air volume ratio of the air curtain at each position is shown in the following table:

[0078] Light direction straight ahead Directly above Left Right rear Front windshield 50% 25% 25% 25% 25% Left window 10% 10% 40% 10% 10% Right window 10% 10% 10% 40% 10% Skylight 25% 50% 20% 20% 25% Rear windshield 5% 5% 5% 5% 30%

[0079] Taking the sun directly in front of the vehicle as an example, the area of ​​the front windshield illuminated by the sun accounts for the highest proportion of the total window area, and the corresponding wind volume accounts for the largest proportion (50%). The area of ​​the rear windshield illuminated by the sun accounts for the lowest proportion of the total window area, and the corresponding wind volume accounts for the smallest proportion (5%).

[0080] In the implementation mode of the present application, by controlling the air volume ratio of the air curtain according to the sunlight information, the air volume of the air curtain can be higher at the window position exposed to the sun, so as to effectively block the heat exchange between the inside and outside of the vehicle. The air volume of the air curtain at other positions can be lower, avoiding the high power consumption problem caused by excessive air volume, which helps to improve the vehicle's cruising range.

[0081] It should be noted that, for the sake of simplicity of description, the aforementioned method embodiments are all expressed as a series of action combinations, but those skilled in the art should know that the present application is not limited to the described order of actions, because according to the present application, certain steps can be performed in other orders.

[0082] like Figure 6 Shown is a schematic structural diagram of an air curtain control device 600 provided in an embodiment of the present application, wherein the air curtain control device 600 is configured on a vehicle.

[0088] In some embodiments of the present application, the starting unit 602 may be specifically used to: obtain a first in-vehicle temperature of the vehicle; and control the air curtain to open according to a corresponding air curtain gear position according to the first in-vehicle temperature.

[0089] In some embodiments of the present application, the starting unit 602 can be specifically used for: if the first in-car temperature is lower than the first in-car temperature threshold, controlling the air curtain to open according to the first air curtain gear; if the first in-car temperature is greater than or equal to the first in-car temperature threshold, controlling the air curtain to open according to the second air curtain gear, and controlling the vehicle air conditioner to turn on, until the vehicle in-car temperature is lower than the first in-car temperature threshold, turning off the vehicle air conditioner, and adjusting the gear of the air curtain to the first air curtain gear, wherein the second air curtain gear is higher than the first air curtain gear.

[0090] In some embodiments of the present application, the starting unit 602 can be specifically used to: control the vehicle air conditioner to turn on according to the corresponding air conditioning gear according to the first vehicle interior temperature, and the cooling capacity of the air conditioning gear is proportional to the first vehicle interior temperature.

[0091] In some embodiments of the present application, the starting unit 602 can be specifically used to: obtain a second vehicle interior temperature of the vehicle after the air conditioner is turned on for a preset period of time; if the second vehicle interior temperature is not lower than the first vehicle interior temperature, then increase the gear of the air conditioner.

[0092] In some embodiments of the present application, the air curtain position when the air curtain is turned on is positively correlated with the window glass temperature.
