[0027] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0028] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0029] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0030] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0031] For ease of understanding, specific application scenarios are further illustrated below.

[0032] See also Figure 1 , which provides a schematic diagram of an application scenario for the embodiment of the present application. Figure 1 As shown, the vehicle 100 generally includes: a controller 101, a window 102, an air conditioner 103, and an air purifier 104. Specifically, the vehicle 100 controls the opening and closing of the window 102, the air conditioner 103, and the air purifier 104 through the controller 101. Among them, the air conditioner 103 can realize external circulation, and can introduce the air outside the vehicle 100 into the interior of the vehicle 100, and at the same time exhaust the air inside the vehicle 100.

[0033] in addition, Figure 1 The vehicle structure shown in the figure is merely an exemplary description and should not be regarded as limiting the scope of protection of the present application.

[0034] In the related art, the air inside the vehicle is generally circulated and exchanged with the air outside the vehicle by adjusting the windows and the air conditioner. However, when the air quality outside the vehicle is poor, or even lower than the air quality inside the vehicle, the purpose of purifying the air quality inside the vehicle cannot be achieved, and it may even have the opposite effect.

[0035] Among them, air quality refers to the concentration level of pollutant gases in the air, which reflects the degree of air pollution. Pollutant gases include harmful gases (such as PM2.5, sulfur dioxide, etc.) and odorous gases (such as ammonia and isoprene produced by sweat secretion). In the embodiment of the present application, if the concentration value of the pollutant gas in the air is greater than or equal to the preset pollutant gas concentration value threshold, the air quality is considered to be substandard; if the concentration value of the pollutant gas in the air is less than the preset pollutant gas concentration value threshold, the air quality is considered to be up to standard.

[0036] In view of the above problems, in the embodiment of the present application, if the air quality inside the vehicle does not meet the standard, and the air quality outside the vehicle meets the standard, the air inside the vehicle is purified by exchanging the air inside the vehicle and outside the vehicle. If the air quality inside the vehicle does not meet the standard, and the air quality outside the vehicle does not meet the standard, the air inside the vehicle is purified by filtering the polluted gas inside the vehicle. Therefore, regardless of whether the air quality outside the vehicle meets the standard, the air inside the vehicle can be purified. This avoids the problem that the air inside the vehicle cannot be purified when the air quality outside the vehicle does not meet the standard.

[0037] Specifically, a detailed description is given below in conjunction with the accompanying drawings and specific embodiments.

[0038] See also Figure 2 , is a flow chart of a vehicle air conditioning method provided in an embodiment of the present application. The method can be applied to Figure 1 The controller shown. Figure 2 As shown, it specifically includes the following steps.

[0039] Step S201: respectively obtaining a first pollutant gas concentration value and a second pollutant gas concentration value.

[0040] In an embodiment of the present application, the first pollutant gas refers to a plurality of pollutants currently present inside the vehicle. For example, the pollutants currently present inside the vehicle include PM2.5 and sulfur dioxide. The first pollutant gas concentration value refers to the concentration values ​​of the plurality of pollutants currently present inside the vehicle. For example, the concentration value of the pollutant PM2.5 currently present inside the vehicle is 5 micrograms per cubic meter, and the concentration value of sulfur dioxide is 0.01 milligrams per cubic meter. Similarly, the second pollutant gas refers to a plurality of pollutants currently present outside the vehicle. The second pollutant gas concentration value refers to the concentration values ​​of the plurality of pollutants currently present outside the vehicle.

[0041] When the first pollutant gas concentration value is less than the preset first pollutant gas concentration value threshold, the air quality inside the vehicle is considered to meet the standard. On the contrary, when the first pollutant gas concentration value is greater than or equal to the preset first pollutant gas concentration value threshold, the air quality inside the vehicle is considered to be substandard. Among them, the first pollutant gas concentration value threshold is a critical value used to determine whether the air quality inside the vehicle meets the standard, including concentration value thresholds of multiple pollutants. For example, the first pollutant gas concentration value threshold includes: PM2.5 concentration value threshold is 10 micrograms / cubic meter, sulfur dioxide concentration value threshold is 0.05 milligrams / cubic meter, etc. The first pollutant gas concentration value threshold is only exemplified here. In actual applications, those skilled in the art can determine the first pollutant gas concentration value threshold according to the types of pollutants that may actually exist inside the vehicle.

[0042] It should be noted that among the multiple pollutants, as long as the concentration value of one pollutant is greater than or equal to the concentration value threshold corresponding to the pollutant, the air quality is considered to be substandard. When the concentration values ​​of all pollutants are less than the corresponding concentration value threshold, the air quality is considered to be up to standard.

[0043] Similarly, the air quality outside the vehicle meets the standard when the second pollutant gas concentration value is less than or equal to the preset second pollutant gas concentration value threshold. The air quality outside the vehicle does not meet the standard when the second pollutant gas concentration value is greater than the preset second pollutant gas concentration value threshold. Among them, the second pollutant gas concentration value threshold is a critical value used to determine whether the air quality outside the vehicle meets the standard, including concentration value thresholds of multiple pollutants.

[0044] The first pollutant gas concentration value threshold value and the second pollutant gas concentration value threshold value may be the same or different.

[0045] In a possible implementation, a first pollutant gas concentration value is measured by a gas sensor inside the vehicle, and a second pollutant gas concentration value is measured by a gas sensor outside the vehicle. The gas sensor can measure all pollutant gas concentration values ​​included in the first pollutant gas concentration value and the second pollutant gas concentration value. The gas sensor can be an electrochemical sensor, a semiconductor sensor, an optical sensor, etc., and the embodiments of the present application are not limited to this.

[0046] The first polluted gas concentration value and the second polluted gas concentration value are measured by the gas sensor, and the measurement result has high accuracy, so that the selection of subsequent air purification strategies is more accurate.

[0047] In the embodiment of the present application, the air quality inside and outside the vehicle is evaluated according to the first pollutant gas concentration value and the second pollutant gas concentration value, that is, it is determined whether the air quality inside and outside the vehicle meets the standard. According to the evaluation results, the air purification strategy inside the vehicle is determined.

[0048] Step S202: If the first pollutant gas concentration value is greater than or equal to the preset first pollutant gas concentration value threshold, and the second pollutant gas concentration value is less than or equal to the preset second pollutant gas concentration value threshold, control opening the vehicle windows and / or air conditioning external circulation.

[0049] In one possible implementation, if the air quality inside the vehicle does not meet the standard and the air quality outside the vehicle meets the standard, the vehicle windows are controlled to open and / or the air conditioner is circulated outside to achieve air exchange between the inside and outside of the vehicle.

[0050] For example, if a user enters the vehicle after sweating, odorous gases such as ammonia are produced due to sweat secretion, which affects the riding experience of the people inside the vehicle. If the air quality outside the vehicle meets the standard at this time, the air exchange between the inside and outside of the vehicle can be achieved by opening the windows. While purifying the odorous gases inside the vehicle as quickly as possible, energy will not be wasted. If the temperature outside the vehicle is high at this time, the air exchange between the inside and outside of the vehicle can be achieved by opening the windows and the air conditioning external circulation. The combination of window ventilation and air conditioning external circulation not only improves the efficiency of purifying odorous gases inside the vehicle, but also ensures the appropriate temperature inside the vehicle, further improving the riding experience.

[0051] In the embodiment of the present application, the air exchange between the inside and outside of the vehicle is achieved by controlling the opening of the vehicle windows and / or the external circulation of the air conditioner. The control of opening the vehicle windows and / or the external circulation of the air conditioner is called the air exchange strategy.

[0052] In practical applications, the air exchange strategy is usually limited by the weather conditions outside the vehicle. For example, when the weather conditions outside the vehicle are severe weather such as heavy rain or hail, it is not suitable to open the car windows.

[0053] See also Figure 3 , which is a flow chart of a method for exchanging air inside and outside a vehicle, for an embodiment of the present application. Figure 3 As shown, step S202 includes steps S301 to S303.

[0054] Step S301: Obtain weather data.

[0055] In a possible implementation, weather data outside the vehicle is acquired through a sunlight and rain sensor.

[0056] By obtaining weather data through the sunlight and rain sensor, it is possible to obtain timely information about whether it is raining at the current location of the vehicle. This method is highly real-time and can accurately determine the actual weather conditions at the current location of the vehicle, making it possible to adjust the air exchange strategy more timely.

[0057] However, the weather data obtained by the sunlight and rainfall sensor has certain limitations. It can only determine whether there is rain outside the vehicle, but cannot determine whether there is snow, sandstorms or other severe weather outside the vehicle, making the basis for adjusting the air exchange strategy not comprehensive enough.

[0058] In a possible implementation, weather data outside the vehicle is acquired through a network.

[0059] By obtaining weather data at the location of the vehicle through the network, various weather conditions at the location of the vehicle can be obtained, such as rain, snow, sandstorm, haze, etc. This method can obtain comprehensive weather data, making the basis for adjusting the air exchange strategy more comprehensive and sufficient.

[0060] However, the way of obtaining weather data through the Internet has certain lags and errors. Since weather forecasts are based on the probability statistics of weather conditions in a certain area based on complex and changeable atmospheric movements, that is, the probability of weather changes caused by the movement of the atmosphere in the area. Therefore, corresponding to the actual weather conditions at the location of the vehicle, there are inevitably certain lags and errors. For example, the weather data of the area where the vehicle is located is obtained through the Internet, and it is rainy in a certain period of time. However, when adjusting the air exchange strategy, heavy rain is falling in other places in the area where the vehicle is located, and the actual weather conditions at the location of the vehicle are not raining, which affects the adjustment of the air exchange strategy.

[0061] In a possible implementation, weather data outside the vehicle is obtained through a sunlight and rainfall sensor and a network.

[0062] This method of obtaining weather data outside the vehicle can not only obtain whether it is raining outside the vehicle in real time through the sunlight and rainfall sensor, but also obtain more comprehensive weather data through the Internet, so that the adjustment of the air exchange strategy is both timely and has sufficient and comprehensive adjustment basis.

[0063] Step S302: If the weather data matches the preset weather conditions, the first pollutant gas concentration value is greater than or equal to the preset first pollutant gas concentration value threshold, and the second pollutant gas concentration value is less than or equal to the preset second pollutant gas concentration value threshold, then control to open the car window.

[0064] In a possible implementation, weather conditions suitable for opening the car windows are tabulated and saved in the controller in advance, and the current weather data is judged whether it is suitable for opening the car windows by looking up the table. There are many weather conditions suitable for opening the car windows, such as sunny days, cloudy days, overcast days, wind speed less than or equal to a preset wind speed threshold, etc. The weather conditions suitable for opening the car windows are only exemplified here. In actual applications, those skilled in the art can determine the weather conditions suitable for opening the car windows based on the impact of actual weather data on opening the car windows.

[0065] By looking up the table to determine whether the current weather data is suitable for opening the car windows, the amount of calculation is greatly reduced, making the controller respond faster, thereby making the adjustment of the air exchange strategy more sensitive.

[0066] In a possible implementation, if the current weather data is suitable for opening the windows, the air quality inside the vehicle does not meet the standards, and the air quality outside the vehicle meets the standards, the windows are controlled to open.

[0067] When the air quality inside the vehicle does not meet the standard, the air inside the vehicle needs to be purified. If the air quality outside the vehicle meets the standard, the air inside the vehicle can be purified by exchanging air between the inside and outside of the vehicle. Since the air exchange strategy is affected by the weather outside the vehicle, if the current weather data is suitable for opening the windows, the air inside the vehicle can be exchanged with the outside of the vehicle by controlling the opening of the windows, thereby achieving air purification inside the vehicle.

[0068] By opening the windows to purify the air inside the vehicle, energy is not wasted. In addition, during the driving process, due to the pressure difference between the inside and outside of the vehicle, the air exchange rate between the inside and outside of the vehicle is fast, making the air purification more efficient.

[0069] A vehicle usually has multiple windows. When the vehicle is driving, by controlling the opening position of the windows, the air exchange rate between the inside and outside of the vehicle can be further increased, thereby improving the efficiency of air purification.

[0070] In a possible implementation, a first target window and a second target window are controlled to be opened, wherein the first target window and the second target window are windows on a diagonal line of the vehicle.

[0071] During the driving process of the vehicle, affected by the pressure difference between the inside and outside of the vehicle, after the diagonal windows of the vehicle are opened, the air convection speed between the inside and outside of the vehicle is greatly improved, thereby further improving the rate of air exchange between the inside and outside of the vehicle, and then improving the efficiency of air purification.

[0072] For example, Figure 4 A schematic diagram of vehicle window positions is provided for an embodiment of the present application. Figure 4 In the vehicle shown, the first window 401 and the fourth window 404 are diagonal windows of the vehicle, and the second window 402 and the third window 403 are diagonal windows of the vehicle. To improve the efficiency of air purification inside the vehicle, the first window 401 and the fourth window 404 can be controlled to open, the second window 402 and the third window 403 can also be controlled to open, or all four windows can be controlled to open.

[0073] It should be pointed out that Figure 4 The schematic diagram of the window positions of a vehicle shown is only an exemplary description of the windows on the diagonal line of the vehicle. In actual applications, those skilled in the art can determine the windows on the diagonal line of the vehicle according to the window positions on the specific vehicle.

[0074] During vehicle driving, affected by the pressure difference between the inside and outside of the vehicle, after the window is opened, the airflow outside the vehicle enters the vehicle too quickly, and air friction generates wind noise. The faster the vehicle travels, the faster the airflow outside the vehicle enters the vehicle, and the greater the wind noise generated. In order to improve the user's car experience, after the window is opened, the impact of wind noise on people inside the vehicle should be reduced.

[0075] In a possible implementation, the window is controlled to open according to the current vehicle speed. Figure 5 , which is a flow chart of a control method for opening a window according to vehicle speed provided in an embodiment of the present application. Figure 5 As shown, step S302 includes steps S501 to S503.

[0076] Step S501: Obtain the current vehicle speed.

[0077] Step S502: Determine the window opening according to the current vehicle speed.

[0078] The higher the current vehicle speed, the greater the pressure difference between the vehicle interior and exterior, the faster the airflow from the exterior into the vehicle interior, and the greater the wind noise generated. Since the higher the vehicle speed, the greater the wind noise, the window opening can be controlled according to the current vehicle speed to reduce wind noise.

[0079] To reduce wind noise, the current vehicle speed and the window opening should be negatively correlated, that is, the higher the current vehicle speed, the smaller the window opening.

[0080] In a possible implementation, the window opening can be determined by looking up a table according to the current vehicle speed.

[0081] For example, the corresponding relationship between the current vehicle speed and the window opening is shown in Table 1: Table 1: It should be pointed out that Table 1 is only an exemplary description of the correspondence between the current vehicle speed and the window opening. In actual applications, those skilled in the art can determine the correspondence table between the current vehicle speed and the window opening according to the actual wind noise generated by the current vehicle speed and the window opening.

[0082] From Table 1, we can see that when the current speed is 30km / h, the window opening is 90%; when the current speed is 60km / h, the window opening is 60%; when the current speed is 100km / h, the window opening is 10%. The window opening is negatively correlated with the current speed, that is, the window opening decreases as the current speed increases.

[0083] In a possible implementation, when the current vehicle speed is higher than a preset vehicle speed threshold, the window opening remains unchanged at a preset minimum window opening.

[0084] In the above scenario, in order to achieve air purification inside the vehicle, the window needs to have a certain opening. When the vehicle speed is too high, in order to achieve the purpose of air purification inside the vehicle, the window no longer decreases with the increase of vehicle speed. For example, the preset speed threshold is 100km / h, and the preset minimum window opening is 10%. Then, if the current vehicle speed is 110km / h, the window opening is still 10%.

[0085] Step S503: Control the vehicle window to open to the vehicle window opening degree.

[0086] According to step S502, the window opening can be determined, and the window can be controlled to be opened to the window opening, so that the air inside the vehicle can be purified and the wind noise generated by opening the window can be reduced as much as possible.

[0087] In an embodiment of the present application, in order to reduce the impact of wind noise on people inside the vehicle, another control method for opening the window is provided.

[0088] In a possible implementation, the window is controlled to open according to the position of the occupant in the vehicle. Figure 6 , which is a flow chart of a control method for opening a window according to the position of a person in the vehicle according to an embodiment of the present application. Figure 6 As shown, step S302 includes steps S601 and S602.

[0089] Step S601: Determine the third target window according to the position of the occupant in the vehicle.

[0090] The position of the occupants in the vehicle is obtained through the occupant position sensing system. The position of the occupants in the vehicle refers to the correspondence between the occupants in the vehicle and the cockpit area (i.e., seats).

[0091] In addition, there is a corresponding relationship with the seat, that is, the window next to the seat.

[0092] If there is no one on a certain seat, and there is a corresponding window for the seat, that is, there is an adjacent window, then the window corresponding to the seat is determined to be the third target window.

[0093] For example, Figure 7A schematic diagram of the correspondence between the windows and seats of a vehicle is provided for the embodiment of the present application. Figure 7 In the vehicle shown, there is a correspondence between window No. 1 701 and seat No. 1 705, that is, window No. 1 701 is the window immediately adjacent to seat No. 1 705, and vice versa, seat No. 1 705 is the seat immediately adjacent to window No. 1 701. Similarly, window No. 2 702 and seat No. 2 706, window No. 3 703 and seat No. 3 707, window No. 4 704 and seat No. 4 708 respectively correspond. In particular, there is no window immediately adjacent to seat No. 5 709.

[0094] According to the position of the people in the car, if there are people in the first seat 705, the second seat 706, and the third seat 707, there are no people in the fourth seat 708 and the fifth seat 709. Since there is no window next to the fifth seat 709, and there is a window next to the fourth seat 708, which is the fourth window 704, the fourth window 704 is determined to be the third target window.

[0095] According to the position of the occupants in the vehicle, if there is someone in seat 1 705, there is no one in seat 2 706, seat 3 707, seat 4 708 and seat 5 709. Since seat 2 706, seat 3 707 and seat 4 708 all have adjacent windows, namely, window 2 702, window 3 703 and window 4 704, a window is randomly selected from the three adjacent windows as the third target window, for example, window 4 704 is randomly selected as the third target window.

[0096] Step S602: controlling to open the third target window.

[0097] Since there is no one sitting in the seat next to the third target window, the wind noise generated after opening the window will not affect the people in the car.

[0098] According to the position of the occupants in the vehicle, the third target window is controlled to open, which can not only achieve air purification inside the vehicle, but also reduce the impact of wind noise generated after opening the third target window.

[0099] Through the above method, after opening the car window, although the impact of wind noise can be reduced, the wind noise still exists. If the occupants use the vehicle's audio system, such as speakers, they need to adjust the output volume of the speakers according to the amount of wind noise.

[0100] See also Figure 8 , which is a flow chart of a method for controlling the output volume of a speaker according to an embodiment of the present application. Figure 8 As shown, after step S503 and / or step S602, steps S801 and S802 are also included.

[0101] Step S801: Obtain the wind noise level of the vehicle window.

[0102] In a possible implementation, the wind noise amount of a vehicle window is acquired by a sensor, wherein the vehicle window refers to an open vehicle window.

[0103] Step S802: adjusting the output volume of the speaker according to the amount of wind noise.

[0104] In a possible implementation, the output volume of the speaker is adjusted according to the amount of wind noise by looking up a table.

[0105] The amount of wind noise is positively correlated with the output volume of the speaker, that is, the output volume of the speaker increases as the amount of wind noise increases.

[0106] After opening the car window, the output volume of the speaker is adjusted according to the amount of wind noise, so that people in the car are not affected by the wind noise and can still hear the audio content output by the speaker, thereby improving the user's riding experience.

[0107] In actual applications, when a vehicle is driving for too long, the concentration of polluted gases inside the vehicle may reach the standard. Since the breathing of people in the vehicle continuously produces carbon dioxide, the concentration of carbon dioxide inside the vehicle increases. A high concentration of carbon dioxide can easily cause occupants to feel sleepy and even affect safe driving. Therefore, when a vehicle is driving for too long, the concentration of carbon dioxide in the air inside the vehicle should be reduced.

[0108] In a possible implementation, if the driving time of the vehicle is greater than or equal to a preset driving time threshold, the vehicle window is controlled to open.

[0109] By controlling the way of opening the windows, the air inside and outside the vehicle can be exchanged, thereby reducing the carbon dioxide concentration in the air inside the vehicle. In addition, when the vehicle is driving, after opening the windows, the air convection speed between the outside and inside of the vehicle is very fast, so that the air exchange efficiency is very high. Therefore, a large amount of air exchange can be carried out in a short period of time, so that the heat inside the vehicle is lost, resulting in a significant reduction in the temperature inside the vehicle in a short period of time, which further has a refreshing effect and avoids the problem of fatigue driving to a certain extent.

[0110] There are usually two ways to achieve air purification inside a vehicle, namely air exchange and air filtration. Since air filtration requires complex filtration of polluted gases inside the vehicle, compared with direct air exchange, air filtration has a slow purification speed and low efficiency. When the air quality outside the vehicle meets the standards, air exchange is usually the preferred method to achieve air purification inside the vehicle.

[0111] Step S303: If the weather data does not match the preset weather conditions, the first pollutant gas concentration value is greater than or equal to the preset first pollutant gas concentration value threshold, and the second pollutant gas concentration value is less than or equal to the preset second pollutant gas concentration value threshold, then control to turn on the air conditioning external circulation.

[0112] In a possible implementation, if the current weather data is not suitable for opening the windows, the air quality inside the vehicle does not meet the standard, and the air quality outside the vehicle meets the standard, the air conditioning external circulation is controlled to be turned on.

[0113] When the air quality inside the vehicle does not meet the standard, but the air quality outside the vehicle meets the standard, if the vehicle windows cannot be opened due to weather restrictions outside the vehicle (such as heavy rain, heavy snow, sandstorms and other bad weather), you can turn on the air conditioning external circulation to introduce the air outside the vehicle into the vehicle and exhaust the air inside the vehicle to the outside of the vehicle, so as to achieve the purpose of air purification inside the vehicle.

[0114] When the air quality inside and outside the vehicle is not up to standard, the purpose of purifying the air inside the vehicle cannot be achieved by air exchange. Therefore, in an embodiment of the present application, a method for purifying the air inside the vehicle by air filtration is provided.

[0115] Step S203: If the first pollutant gas concentration value is greater than or equal to the preset first pollutant gas concentration value threshold, and the second pollutant gas concentration value is greater than the preset second pollutant gas concentration value threshold, then control to turn on the air purifier.

[0116] In a possible implementation, if the air quality inside the vehicle does not meet the standard and the air quality outside the vehicle does not meet the standard, the air purifier is controlled to be turned on to filter the polluted gas inside the vehicle.

[0117] The air purifier can filter out harmful gases and odorous gases in the air, as well as bacteria and viruses in the air, thereby achieving the purpose of purifying the air inside the vehicle.

[0118] In actual applications, users are usually allowed to actively turn on the air purifier to purify the air inside the vehicle. If the user is in the car, he can turn on the air purifier manually. In some scenarios, the user is not in the car, but also wants to turn on the air purifier to purify the air inside the vehicle. For example, after the vehicle has been parked for a long time, the air quality inside the vehicle is not up to standard. Before using the car, the user hopes to purify the air inside the vehicle in advance through the air purifier. Therefore, an embodiment of the present application provides a way to remotely turn on the air purifier in the car.

[0119] In a possible implementation, the air purifier is controlled to be turned on according to a remote control instruction.

[0120] The user sends a remote control command to the vehicle's controller through a third-party platform such as a mobile phone software or a website. The remote control command can control the vehicle's air purifier to turn on. The controller receives the remote control command and controls the air purifier to turn on.

[0121] By turning on the purifier through remote control, in specific application scenarios, it is convenient for users to purify the air inside the vehicle and improve the user's car experience.
