[0038] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0039] The average air age is used to quantitatively evaluate the quality of airflow organization within the cockpit. It reflects the quality of local airflow distribution and the freshness of the air within the cockpit. Combined with temperature and velocity, it can be used to evaluate the quality of the ventilation system. The smaller the air age, the fresher the air and the better the air quality. Air age is related to the air volume, air temperature, and specific environmental conditions. The greater the air volume, the smaller the air age. The air at a specific point in the cockpit is composed of a large number of different air microclusters. The air age at a specific point is the average air age of all air microclusters at that point. Therefore, the average air age can be numerically calculated to evaluate the freshness of the air. In principle, a smaller air age indicates fresher air and higher air quality.

[0040] While driving, high-quality air makes the driver and passengers feel refreshed and happy. However, in summer and winter, poor air circulation in the cockpit can cause passengers to experience stale air and even smell unpleasant odors, significantly reducing driving comfort. Existing in-car air conditioning modes require manual adjustment, making it difficult for users to quickly assess cockpit air quality, leading to the aforementioned issues.

[0041] In view of this, the present application provides a method for controlling a vehicle air conditioner. The technical concept adopted is: by detecting the oxygen content at different positions in the vehicle from the air inlet of the air conditioner to the exhaust port 3 of the vehicle, the current air quality parameters and preset quality parameters inside the vehicle are determined, and finally the target state of the vehicle air conditioner 1 is controlled according to the current air quality parameters and the preset quality parameters, wherein the target state includes one or more of the circulation mode, the opening degree of the air conditioner, and the wind speed.

[0042] Reference Figure 1 , Figure 1 Shows the vehicle air conditioning mode control flow chart, such as Figure 1 As shown, the following steps are included:

[0043] Step S21: Obtaining the oxygen content at multiple locations inside the vehicle from the air-conditioning outlet 2 to the vehicle exhaust outlet 3;

[0044] Step S22: determining a current air quality parameter and a preset air quality parameter inside the vehicle based on the initial oxygen content at the air-conditioning outlet 2 and the oxygen content at each of the plurality of locations;

[0045] Step S23: Based on the current air quality parameter and the preset quality parameter, the target state of the vehicle air conditioner 1 is controlled, wherein the target state includes one or more of the circulation mode, the opening degree of the air conditioner, and the wind speed.

[0046] In an embodiment of the present application, obtaining the oxygen content at multiple positions inside the vehicle from the air-conditioning outlet 2 to the vehicle exhaust outlet 3 is performed when the vehicle air-conditioning 1 is in the external circulation mode, that is, based on the current air quality parameters and the preset quality parameters, one or more of the circulation mode, the opening degree of the air-conditioning, and the wind speed of the vehicle air-conditioning 1 are controlled, wherein the control of the circulation mode is adjusted based on the vehicle being in the external circulation mode.

[0047] In an embodiment of the present application, the opening degree and wind speed of the vehicle air conditioner 1 can be controlled based on the current air quality parameter and the preset quality parameter. The opening degree of the vehicle air conditioner 1 is the percentage of the vehicle air conditioner power turned on. For example, an opening degree of 0% means the air conditioner is completely off, an opening degree of 50% means the air conditioner is half-on, and an opening degree of 100% means the air conditioner is fully on. If the current air quality parameter inside the vehicle is higher than the preset quality parameter, indicating that the air inside the cabin is worse than the ambient air, the opening degree of the air conditioner is increased; if the current air quality parameter inside the vehicle is equal to the preset quality parameter, the current opening degree of the air conditioner is maintained unchanged; if the current air quality parameter inside the vehicle is lower than the preset quality parameter, the opening degree of the air conditioner is decreased.

[0048] The air conditioning wind speed is the speed of the wind blowing into the vehicle cabin. If the current air quality parameter inside the vehicle is higher than the preset quality parameter, it means that the air inside the cabin is worse than the air in the external environment, and the air conditioning wind speed is increased; if the current air quality parameter inside the vehicle is equal to the preset quality parameter, the current air conditioning wind speed remains unchanged; if the current air quality parameter inside the vehicle is lower than the preset quality parameter, the air conditioning wind speed is reduced.

[0049] In the embodiment of the present application, the device for obtaining the oxygen content at multiple locations within the vehicle, from the air conditioning outlet 2 to the vehicle exhaust outlet 3, in step S21, may be an oxygen sensor. There may be multiple oxygen sensors, each disposed along the length of the vehicle from the air conditioning outlet 2 to the vehicle exhaust outlet 3. The multiple sensors can measure the oxygen content at different locations within the vehicle to determine the average oxygen content of the entire vehicle.

[0050] In the examples of this application, refer to Figure 2 There may be four oxygen sensors, including a first sensor 4, a second sensor 5, a third sensor 6, and a fourth sensor 7. The first sensor 4 is disposed on a front seat 8 in the vehicle, the second sensor 5 is disposed above a front seat headrest 9, the third sensor 6 is disposed on a rear seat 10 in the vehicle, and the fourth sensor 7 is disposed above a rear seat headrest 11. The vehicle cabin includes an onboard air conditioner 1, an air conditioner outlet 2, and a vehicle exhaust vent 3. The first sensor 4, the second sensor 5, the third sensor 6, and the fourth sensor 7 are all located between the air conditioner outlet 2 and the vehicle exhaust vent 3. In the embodiment of the present application, the oxygen content data of the first sensor 4, the second sensor 5, the third sensor 6, and the fourth sensor 7 can be used as the oxygen content of each of the multiple locations in the embodiment of the present application. By measuring the oxygen content of each of the multiple locations, it is ensured that the oxygen sensor can comprehensively evaluate the oxygen content in the entire vehicle cabin, thereby ensuring the reliability of the measurement data.

[0051] In an embodiment of the present application, the first sensor 4 is set as the oxygen sensor closest to the air-conditioning outlet 2. In the external circulation mode of the vehicle air-conditioning 1, the wind blown out from the vehicle air-conditioning 1 can first blow to the position of the first sensor 4.

[0052] In the embodiment of the present application, the oxygen content at multiple locations inside the vehicle from the air-conditioning outlet 2 to the vehicle exhaust outlet 3 is obtained respectively, including:

[0053] For each of the positions, the total oxygen content of the position within a preset time period is obtained, and the total oxygen content is used as the oxygen content of the position.

[0054] In the embodiment of the present application, for each of the positions, obtaining the total oxygen content of the position within a preset time period includes:

[0055] For each of the positions, obtaining the oxygen content of the position at each moment within a preset time period;

[0056] The oxygen content at each moment is accumulated to obtain the total oxygen content at that position.

[0057] The calculation formula for the total oxygen content within the preset time is:

[0058]

[0059] Among them, t is the preset time, C p (t) is the oxygen content measured by the oxygen sensor within the preset time t, and p can be 1, 2, 3, or 4, representing the numbers of oxygen sensors at different positions, for example, p1 is the first sensor 4, and p2 is the second sensor 5.

[0060] In the embodiment of the present application, an initial oxygen sensor is provided at the air-conditioning outlet 2. Since the air-conditioning outlet 2 directly draws outside air into the vehicle, the drawn air has not yet been exchanged with the air in the cabin. Therefore, in the present application, the oxygen content measured by the initial oxygen sensor at the air-conditioning outlet 2 is determined to be the initial oxygen content.

[0061] In the embodiment of the present application, the current air quality parameter inside the vehicle is determined based on the initial oxygen content at the air-conditioning outlet 2 and the oxygen content at each of the multiple locations, including:

[0062] Determine the ratio of the oxygen content at each location to the initial oxygen content to obtain the air age at each location. The calculation formula for air age is:

[0063]

[0064] Air age, also known as the air age of an air particle, refers to the time it takes for air to enter a room and reach a certain point in the room. It reflects the freshness of the indoor air. It can comprehensively measure the ventilation effect of the room and is an important indicator for evaluating indoor air quality.

[0065] The oxygen content at each position may be the oxygen content measured by an oxygen sensor, or the total oxygen content at the position within a preset time period.

[0066] In this embodiment of the present application, the average of the air ages at these multiple locations is used as the current air quality parameter. This average air age calculated from these multiple locations can reflect the air quality of the entire vehicle cabin over a preset time period. The current air quality parameter, calculated as the ratio of the total oxygen content to the initial oxygen content over the preset time period, is expressed in units of / s, i.e., the air age is expressed in units of / s.

[0067] From the above, it can be seen that the oxygen sensor closest to the air-conditioning outlet 2 is the first sensor 4. The oxygen content of the air measured by the first sensor 4 is the initial oxygen content, which is the oxygen content in the above formula. The initial oxygen content is the oxygen content in the air first blown into the cabin by the car air conditioner 1, which can be identified as the oxygen content of the air in the external environment.

[0068] In the embodiment of the present application, the preset quality parameter is the ratio of the total oxygen content of the first sensor 4 within the preset time t to the initial oxygen content. The preset quality parameter is the air age of the external environment, which indicates the freshness of the air in the external environment.

[0069] In the embodiment of the present application, the circulation mode of the vehicle air conditioner 1 is controlled based on the current air quality parameter and the preset quality parameter, including:

[0070] When the current air quality parameter is higher than the preset quality parameter, the circulation mode of the vehicle air conditioner 1 is set to the external circulation mode, and the air intake volume of the blower of the vehicle air conditioner 1 is increased.

[0071] When the current air quality parameter is lower than or equal to the preset quality parameter, the current external circulation mode of the vehicle air conditioner 1 is maintained.

[0072] The higher the current air quality parameter value, the lower the cabin air quality; conversely, the lower the current air quality parameter value, the better the cabin air quality. When the current air quality parameter is higher than the preset quality parameter, it indicates that the cabin air quality is lower than the outside air quality. Therefore, it is necessary to increase the air intake volume of the blower in the vehicle air conditioner 1 to accelerate the circulation of the cabin air, so that the cabin air circulates more quickly and improves the cabin air quality.

[0073] When the current air quality parameter is lower than or equal to the preset quality parameter, it means that the air quality in the cabin reaches the preset standard or is higher than the preset standard. At this time, the external circulation of the vehicle air conditioner 1 can be maintained and it can operate at normal power. This setting not only ensures the air quality in the cabin, but also effectively saves energy and avoids unnecessary energy waste.

[0074] In general, the air quality in the cabin can be divided into:

[0075] High-quality cabin environment, that is, the air age in the cabin is less than 120 / s;

[0076] Normal cabin environment, that is, the air age in the cabin is between 120 and 150 / s;

[0077] Poor cabin environment, that is, the air age in the cabin is greater than 150 / s.

[0078] A value within the above-mentioned range of 120 to 150 / s can be used as a preset quality parameter in one case. The preset quality parameter in this application is determined by the quality of the outside air. In this application, since the air at the air-conditioning outlet 2 is directly extracted from the outside environment and has not yet been fully exchanged with the air in the cabin, the air quality of the air extracted into the cabin from the air-conditioning outlet 2 can be considered to be the outside air quality, and the outside air quality is the preset quality parameter. The air quality of this air-conditioning outlet 2 can then be used as a reference for comparison with the air quality in the cabin. For example, when the current air quality parameter in the cabin is lower than the preset air quality, the air quality is good. If the current air quality parameter is higher than the preset air quality, the air quality is poor.

[0079] It is worth noting that the air quality determined in this application is relative. That is, the air quality is determined by comparing the current cabin air quality with the air quality of the vehicle's current external environment. The preset quality parameters will vary depending on the current environment and are not fixed values.

[0080] In the embodiment of the present application, the air quality parameter in the external environment is determined based on the initial oxygen content on the air-conditioning outlet 2;

[0081] In the embodiment of the present application, based on the initial oxygen content at the air-conditioning outlet 2, the air quality parameters in the external environment are determined, including:

[0082] The ratio of the total oxygen content at the air-conditioning outlet 2 within a preset time to the initial oxygen content is used as the air quality parameter in the external environment.

[0083] If the preset quality parameter is higher than the current air quality parameter inside the vehicle, it indicates that the outside air is worse than the air inside the cabin. The vehicle air conditioner 1 is controlled to operate in internal circulation mode. Since the outside air quality is worse than the air inside the cabin, continuing the external circulation of the vehicle air conditioner 1 would introduce poor air into the cabin, causing the air inside the cabin to deteriorate. Therefore, the internal circulation mode of the vehicle air conditioner 1 is activated to maintain the current air quality level inside the cabin.

[0084] Based on the current air quality parameter and the preset quality parameter, the circulation mode of the vehicle air conditioner 1 is controlled, including:

[0085] When the air quality parameter in the external environment is not higher than the preset quality parameter, the circulation mode of the vehicle air conditioner 1 is controlled based on the current air quality parameter and the preset quality parameter. When the air quality parameter in the external environment is not higher than the preset quality parameter, the air quality of the external environment meets or exceeds the standard of normal air, and external circulation can be performed normally.

[0093] Optionally, the device may further include:

[0094] The air age calculation module is used to determine the ratio of the oxygen content at each position to the initial oxygen content, that is, to calculate the air age at each position, and use the average value of the air ages of the multiple positions as the current air quality parameter.

[0095] Optionally, the device may further include:

[0096] Air conditioning mode control module, including:

[0097] Air conditioning external circulation enhancement module: used to keep the circulation mode of the vehicle air conditioner 1 in the external circulation mode and increase the air intake volume of the blower of the vehicle air conditioner 1 when the current air quality parameter is higher than the preset quality parameter.
