[0024] In order to make the purpose, technical solutions and advantages of the present application more clear, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0025] With the rapid development of automobile industry technology, there are more and more glass components on the automobile, and the area occupied by the glass is getting larger and larger. In summer, the temperature in the car rises sharply due to the solar radiation through the car glass, which requires higher cooling capacity of the vehicle air conditioner to maintain the comfort of the passenger cabin, and higher cooling performance often brings higher power consumption, affecting the vehicle endurance.

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

[0027] To illustrate the technical solution of this application, specific embodiments are described below.

[0028] Figure 1 This illustration shows a schematic flowchart of an air curtain control method according to an embodiment of this application. This method can be applied to vehicles. The term "vehicle" can refer to hybrid electric vehicles, pure electric vehicles, gasoline-powered vehicles, or other types of vehicles; this application does not impose any limitations on this.

[0029] In embodiments of this application, the vehicle may be equipped with an air curtain, which can be used to cover the vehicle window glass.

[0030] Specifically, an air curtain is an "air wall" formed by high-speed airflow. For example... Figure 2 As shown, taking an air curtain covering a car window as an example, air ducts can be installed on the door panel. Cold air is ejected through small nozzles, and the airflow is amplified to cover the entire car window. The airflow of the air curtain is low-temperature air, which covers the car window to isolate the airflow 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 this application, the air curtain can work in conjunction with an air conditioning system to evenly distribute cool air to all corners of the room, thereby improving indoor air circulation, increasing cooling efficiency, and enhancing comfort. For example... Figure 3 As shown, taking an air curtain covering the car window as an example, when the airflow reaches the upper door frame, it can flow vertically towards the passenger compartment along the window to participate in the airflow circulation within the passenger compartment.

[0032] It should be noted that the air curtain in the embodiments of this application may include, but is not limited to: an air curtain located at the front windshield, an air curtain located at the left window, an air curtain located at the right window, an air curtain located at the rear windshield, and an air curtain located at the sunroof. This application does not limit the scope of the air curtain.

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

[0034] Step S101: Obtain the temperature of the car window glass.

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

[0036] Step S102, when the vehicle window glass temperature is greater than or equal to the first glass temperature threshold, the air curtain of the vehicle is controlled to be turned on.

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

[0038] In the embodiments of the present application, when the vehicle window glass temperature is less than the first glass temperature threshold, the temperature inside the vehicle is generally not lower than this temperature, so the air curtain does not need to be started at this time. For example, when the vehicle window glass temperature Tglass < 26℃, the air curtain is not started. When the vehicle window glass temperature is greater than or equal to the first glass temperature threshold, the passenger compartment may be heated due to heat exchange with the environment outside the vehicle, and at this time the air curtain of the vehicle can be controlled to be turned on.

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

[0040] In the embodiments of the present application, the sunlight information can 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 proportion 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 air flow of the air curtain, which can play a stronger blocking role on the inside and outside environment of the vehicle.

[0041] In the embodiments of the present application, by obtaining the vehicle window glass temperature, when the vehicle window glass temperature is greater than or equal to the first glass temperature threshold, the air curtain of the vehicle covering the vehicle window glass is controlled to be turned on, 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, the solar heat radiation can be weakened, and the heat exchange between the inside and outside environment of the vehicle can be blocked, so that the power required by the vehicle air conditioner can be reduced, and the energy consumption of the vehicle can be reduced. On the other hand, according to the sunlight information, the air volume ratio of the air curtain is controlled, which can adapt the air volume of the air curtain to the sunlight condition, avoid the problem of temperature rise of the passenger compartment caused by too low air volume, thereby reducing the energy consumption of the vehicle and helping to improve the vehicle range.

[0042] In some embodiments of the present application, as shown in Figure 4 controlling the air curtain of the vehicle to be turned on can include steps S401 to S402.

[0043] Step S401, obtaining a first in-vehicle temperature of the vehicle.

[0044] The first in-vehicle temperature refers to the temperature in the passenger compartment when the air curtain is about to start, and can refer to the average temperature in the passenger compartment. The first in-vehicle temperature can be detected based on a temperature sensor in the passenger compartment.

[0045] Step S402, controlling the air curtain to start according to the corresponding air curtain gear according to the first in-vehicle temperature.

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

[0047] The first in-vehicle temperature can reflect the temperature in the passenger compartment, and according to the first in-vehicle temperature, the air curtain can be controlled to start according to the corresponding air curtain gear.

[0048] Specifically, as shown in Figure 5 According to the first in-vehicle temperature, the air curtain can be controlled to start according to the corresponding air curtain gear, which can include steps S501 to S502.

[0049] Step S501, if the first in-vehicle temperature is less than a first in-vehicle temperature threshold, the air curtain is controlled to start according to the first air curtain gear.

[0050] Step S502, if the first in-vehicle temperature is greater than or equal to the first in-vehicle temperature threshold, the air curtain is controlled to start according to the second air curtain gear, and the vehicle-mounted air conditioner is controlled to start, and after the in-vehicle temperature of the vehicle is less than the first in-vehicle temperature threshold, the vehicle-mounted air conditioner is turned off, and the gear of the air curtain is adjusted to the first air curtain gear.

[0051] The second air curtain gear is higher than the first air curtain gear.

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

[0053] If the first vehicle interior temperature is greater than or equal to the first vehicle interior temperature threshold, indicating that the temperature in the passenger compartment is too high, on the one hand, the air curtain needs to be controlled to be opened at a higher second air curtain gear position to block the heat exchange between the inside and outside of the vehicle while giving a higher cooling effect, and at the same time, the vehicle-mounted air conditioner needs to be controlled to be turned on to make the passenger compartment quickly return to a suitable temperature. As the temperature in the vehicle decreases, when the temperature in the vehicle is less than the first vehicle interior temperature threshold, the vehicle-mounted air conditioner can be turned off, and the air curtain gear position can be adjusted to the first air curtain gear position, which can keep the temperature in the passenger compartment suitable and reduce the high power consumption problem caused by the high-power operation of the vehicle-mounted air conditioner and the air curtain.

[0054] In some embodiments of the present application, controlling the vehicle-mounted air conditioner to be turned on can include: controlling the vehicle-mounted air conditioner to be turned on at a corresponding air conditioner gear position according to the first vehicle interior temperature.

[0055] In some embodiments of the present application, the cooling capacity of the air conditioner gear position is proportional to the first vehicle interior temperature.

[0056] Specifically, when the first vehicle interior temperature is less than or equal to the second vehicle interior temperature threshold, the vehicle-mounted air conditioner can be controlled to be turned on at the first air conditioner gear position. When the first vehicle interior temperature is greater than the second vehicle interior temperature threshold, the vehicle-mounted air conditioner can be controlled to be turned on at the second air conditioner gear position.

[0057] In some embodiments of the present application, the cooling capacity of the second air conditioner gear position is higher than the cooling capacity of the first air conditioner gear position, so that the passenger compartment can be quickly returned to a suitable temperature.

[0058] In some embodiments of the present application, after controlling the vehicle-mounted air conditioner to be turned on, the method can further include: obtaining a second vehicle interior temperature after the vehicle-mounted air conditioner is turned on for a preset time length. If the second vehicle temperature does not decrease compared with the first vehicle interior temperature, the gear position of the air conditioner is increased.

[0059] In some embodiments of the present application, the preset time length can be set according to actual needs, for example, it can be 10 minutes, 15 minutes, etc. After the vehicle-mounted air conditioner is turned on for the preset time length, the temperature in the passenger compartment is detected again to obtain the second vehicle interior temperature. If the second vehicle interior temperature does not decrease compared with the first vehicle interior temperature, it indicates that the current cooling capacity is insufficient, and the gear position of the air conditioner needs to be increased to improve the cooling capacity of the air conditioner.

[0060] If the second vehicle interior temperature decreases compared with the first vehicle interior temperature, the gear position of the air conditioner can be decreased. When the temperature in the vehicle is less than the first vehicle interior temperature threshold, the vehicle-mounted air conditioner can be turned off, and the gear position of the air curtain can be adjusted to the first air curtain gear position.

[0061] It can be understood that by gradually reducing the gear positions of the air curtain and the vehicle-mounted air conditioner according to the real-time situation of the vehicle interior temperature, or even turning off the vehicle-mounted air conditioner, the energy consumption of the vehicle can be effectively reduced, and the cruising range of the vehicle can be improved.

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

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

[0064] The following is illustrated by way of example:

[0065] Case one, when 26℃≤ temperature of vehicle window glass Tglass≤ 30℃:

[0066] If the first vehicle cabin temperature Tcabin< the first vehicle cabin temperature threshold 24℃, strategy ① is executed: turn on the air curtain system and adjust to level one, and do not turn on the vehicle-mounted air conditioner.

[0067] If the first vehicle cabin temperature threshold 24℃≤ the first vehicle cabin temperature Tcabin≤ the second vehicle cabin temperature threshold 30℃, strategy ② is executed: turn on the air curtain and adjust to level two (higher than level one), and turn on the vehicle-mounted air conditioner and adjust to level three; after a preset time period of 10 minutes, continue to monitor the vehicle cabin temperature to obtain the second vehicle cabin temperature Tcabin, if the second vehicle cabin temperature Tcabin decreases to below the first vehicle cabin temperature threshold 24℃, execute strategy ①, if the temperature is maintained at 24-30℃, keep the air curtain level unchanged, increase the air conditioning level to level five, continuously monitor the vehicle cabin temperature Tcabin and adjust to the corresponding strategy. If the second vehicle cabin temperature Tcabin increases to more than 30℃, execute strategy ③.

[0068] If the first vehicle cabin temperature Tcabin> 30℃, execute strategy ③: turn on the air curtain and adjust to level two, and turn on the vehicle-mounted air conditioner and adjust to level five; after a preset time period of 10 minutes, continue to monitor the vehicle cabin temperature to obtain the second vehicle cabin temperature Tcabin, if the second vehicle cabin temperature Tcabin decreases to below the first vehicle cabin temperature threshold 24℃, execute strategy ①, if the second vehicle cabin temperature Tcabin decreases to 24-30℃, execute strategy ②, if the temperature continues to be maintained at more than 30℃, keep the air curtain level unchanged, increase the air conditioning level to level seven, continuously monitor the vehicle cabin temperature Tcabin and adjust to the corresponding strategy.

[0069] Case two, when the temperature of the vehicle window glass Tglass> 30℃:

[0070] If the first temperature in the car Tcabin < the first temperature threshold in the car 24℃, strategy IV is executed: the air curtain system is turned on and adjusted to the second gear, and the vehicle air conditioner is not turned on. It can be understood that the glass temperature in case two is higher than that in case one. Similarly, in the case of the first temperature in the car Tcabin < the first temperature threshold in the car 24℃, strategy IV requires a higher air curtain gear than strategy I.

[0071] If the first temperature threshold in the car 24℃ ≤ the first temperature in the car Tcabin ≤ the second temperature threshold in the car 30℃, strategy V is executed: the air curtain is turned on and adjusted to the third gear, and the vehicle air conditioner is turned on and adjusted to the fifth gear; after a preset time of 15 minutes, the second temperature in the car Tcabin is continuously monitored, if the second temperature in the car Tcabin decreases to below the first temperature threshold in the car 24℃, strategy IV is executed, if the second temperature in the car Tcabin is maintained between 24-30℃, the air curtain gear is kept unchanged, the air conditioner gear is increased to five gears, the temperature in the car Tcabin is continuously monitored and adjusted to the corresponding strategy, if the second temperature in the car Tcabin increases above 30℃, strategy VI is executed. It can be understood that the glass temperature in case two is higher than that in case one. Similarly, in the case of the first temperature threshold in the car 24℃ ≤ the first temperature in the car Tcabin ≤ the second temperature threshold in the car 30℃, strategy V requires a higher air curtain gear and air conditioner gear than strategy II.

[0072] If the first temperature in the car Tcabin > 30℃, strategy VI is executed: the air curtain is turned on and adjusted to the third gear, and the vehicle air conditioner is turned on and adjusted to the seventh gear; after a preset time of 15 minutes, the second temperature in the car Tcabin is continuously monitored, if the second temperature in the car Tcabin decreases to below the first temperature threshold in the car 24℃, strategy IV is executed, if the second temperature in the car Tcabin decreases to 24-30℃, strategy V is executed, if the second temperature in the car Tcabin continues to be maintained above 30℃, the air curtain gear is kept unchanged, if the air conditioner gear can continue to be increased, the air conditioner gear is increased, if the air conditioner gear is the highest of seven gears, the air conditioner gear is kept unchanged, the temperature in the car Tcabin is continuously monitored and adjusted to the corresponding strategy. Similarly, the glass temperature in case two is higher than that in case one. Similarly, in the case of the first temperature in the car Tcabin > 30℃, strategy VI requires a higher air curtain gear and air conditioner gear than strategy III.

[0073] In the embodiments of the present application, the air curtain and air conditioner gears 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 vehicle air conditioner does not need to be in a high-power running state for a long time, which helps to improve the driving comfort and power economy.

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

[0075] Specifically, in some embodiments of the present application, the sunlight information can include a proportion of an area of each vehicle window irradiated by the sun to a total vehicle window area; and the air volume proportion of the air curtain can be controlled according to the sunlight information, which can include: determining the air volume proportion of the air curtain at each window position according to the proportion. Wherein, the air volume proportion is positively correlated with the proportion.

[0076] Specifically, for each window, the proportion of the sun-irradiated area to the total window area can be calculated to analyze the direction of the sunlight. The greater the proportion of the sun-irradiated area to the total window area, the more the window is oriented towards the sun, and the air volume proportion of the air curtain at the window position should be greater. In this way, for the window with a larger sun-irradiated area, the air curtain covering the window glass will operate at a higher air volume proportion, thereby reducing the high-intensity solar radiation. For the window not irradiated by the sun, the air curtain covering the window glass will operate at a lower air volume proportion, thereby reducing power consumption.

[0077] For example, the air volume proportions of the air curtains at different positions are shown in the following table:

[0078] Illumination direction Straight ahead Directly above Left side Right side Rear Front window 50％ 25％ 25％ 25％ 25％ Left window 10％ 10％ 40％ 10％ 10％ Right window 10％ 10％ 10％ 40％ 10％ Sunroof 25％ 50％ 20％ 20％ 25％ Rear window 5％ 5％ 5％ 5％ 30％

[0079] Taking the sun in front of the vehicle as an example, the proportion of the area of the front windshield irradiated by the sun to the total window area is the highest, and the corresponding air volume proportion is the largest (50%); the proportion of the area of the rear windshield irradiated by the sun to the total window area is the lowest, and the corresponding air volume proportion is the smallest (5%).

[0080] In the embodiments of the present application, by controlling the air volume proportion of the air curtain according to the sunlight information, the air volume of the air curtain at the position of the window irradiated by the sun can be higher to effectively block the heat exchange between the inside and outside of the vehicle, and the air volume of the air curtain at other positions can be lower to avoid the problem of high power consumption caused by high air volume, which helps to improve the vehicle's range.

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

[0090] In some embodiments of the present application, the starting unit 602 can be specifically configured to control the vehicle-mounted air conditioner to be turned on at a corresponding air conditioner gear according to the first vehicle interior temperature, the cooling capacity of the air conditioner gear being positively correlated with the first vehicle interior temperature.
