[0002] In-vehicle air conditioning systems, there are two different air circulation modes: internal and external. The main difference lies in the source and circulation path of the air. In internal circulation, the air inside the vehicle circulates within the air conditioning system without exchanging with the outside air. In external circulation, outside air enters the vehicle through the air conditioning system and exchanges with the inside air. This introduction of fresh air can dilute odors and improve the air quality inside the vehicle.

[0003] Excessive fresh air intake increases the energy consumption of the air conditioning system, while insufficient fresh air intake can lead to poor passenger comfort.

DETAILED DESCRIPTION

[0023] The following describes the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art will readily appreciate the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the various details in this specification may be modified or altered based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are intended only to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0024] It should be noted that the illustrations provided in the following embodiments are merely schematic illustrations of the basic concept of the present invention. Therefore, the illustrations only show components related to the present invention and are not drawn according to the number, shape, and size of components in actual implementation. In actual implementation, the type, quantity, and proportion of each component may be changed arbitrarily, and the component layout may also be more complex.

[0025] In the following description, numerous details are discussed to provide a more thorough explanation of the embodiments of the present invention. However, it will be apparent to those skilled in the art that the embodiments of the present invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring the embodiments of the present invention.

[0026] See also Figure 1 , Figure 1 FIG. 1 is a flow chart of a method for determining the amount of fresh air introduced into a vehicle air conditioner according to an exemplary embodiment of the present invention. Figure 1 As shown, in an exemplary embodiment, the method for determining the amount of fresh air introduced by the vehicle air conditioner includes steps S110 to S130, which are described in detail as follows: Step S110, obtaining information on air pollutants inside and outside the vehicle, and determining an initial minimum fresh air introduction amount based on the information on air pollutants inside and outside the vehicle; Step S120, obtaining a fresh air effectiveness coefficient, wherein the fresh air effectiveness coefficient is used to characterize the effectiveness of fresh air from the air outlet in the vehicle to the passenger breathing zone; Step S130 : determining a target minimum fresh air introduction amount for controlling fresh air introduction of the vehicle air conditioner based on the initial minimum fresh air introduction amount and the fresh air effectiveness coefficient.

[0027] In some embodiments, the above steps S110 to S130 may be performed when the air conditioner is started and the concentration of air pollutants in the vehicle exceeds a concentration threshold of air pollutants in the vehicle.

[0028] In other embodiments, when the air conditioner is not started and the concentration of air pollutants in the vehicle exceeds the concentration threshold of air pollutants in the vehicle, a prompt may be sent to the user asking whether to introduce fresh air. When the user confirms to introduce fresh air, the air conditioner is controlled to start, and then the above steps S110 to S130 are executed.

[0029] The introduction of fresh air based on the initial minimum fresh air volume in step S110 can meet the comfort requirements of the occupants at the vehicle's air outlet. However, since the effectiveness of the fresh air decreases from the vehicle's air outlet to the occupant's breathing zone, the occupants' comfort may be poor in the occupant's breathing zone.

[0030] Based on this, in step S120, an embodiment of the present invention obtains a fresh air effectiveness coefficient. The fresh air effectiveness coefficient is used to quantify the effectiveness of fresh air from the vehicle's air outlet to the occupant's breathing zone. In step S130, a target minimum fresh air introduction amount for introducing fresh air is determined based on the initial minimum fresh air introduction amount and the fresh air effectiveness coefficient. Because the determination of the target minimum fresh air introduction amount incorporates the fresh air effectiveness coefficient, even if the effectiveness of the fresh air to the occupant's breathing zone is attenuated, controlling the fresh air based on the target minimum fresh air introduction amount can still meet occupant comfort requirements.

[0031] As an example, the above target minimum fresh air introduction rate can be determined by the following formula: (1) Where, The minimum amount of fresh air introduced is the target. is the initial minimum fresh air introduction volume, is the fresh air effectiveness coefficient.

[0032] The target minimum fresh air volume is used to control the amount of fresh air introduced into the vehicle. Specifically, the target minimum fresh air volume is used to control the minimum air volume for the vehicle's external circulation. If the total air volume is also determined and is greater than the target minimum fresh air volume, the internal circulation air volume can be determined based on the difference between the total air volume and the target minimum fresh air volume.

[0033] In an embodiment of the present invention, the target minimum fresh air introduction amount can be determined through the above steps S110 to S130. The target minimum fresh air introduction amount is the minimum fresh air introduction amount to ensure the comfort of the members. Introducing fresh air based on the target minimum fresh air introduction amount is conducive to balancing vehicle energy consumption and passenger comfort.

[0034] The effectiveness of the fresh air from the air outlet to the passenger breathing zone is attenuated. Furthermore, the effectiveness of the fresh air decreases as the horizontal distance from the air outlet to the passenger breathing zone increases.

[0035] Based on this, in some embodiments, the above step S120 includes: Obtaining the position of the opened air outlet in the vehicle and the center position of the occupant in the vehicle; Determining a fresh air attenuation distance based on a distance from a position of the opened air outlet in the vehicle to a center position of an occupant in the vehicle; Based on the fresh air attenuation distance, the fresh air effectiveness coefficient is determined, wherein the fresh air effectiveness coefficient is negatively correlated with the fresh air attenuation distance.

[0036] The occupant breathing zone is related to the distribution of occupants. In this embodiment of the present invention, the center position of the occupant in the vehicle is obtained and regarded as the occupant breathing zone. The center position of the occupant in the vehicle can be determined using relevant sensing methods (such as image sensing and infrared sensing).

[0037] When there is only one open air outlet in the car, the distance from the position of the opened air outlet to the center position of the occupants in the car is the fresh air attenuation distance; when there are multiple open air outlets in the car, the distances from the positions of the multiple opened air outlets to the center position of the occupants in the car can be filtered (such as median filtering or simple average filtering, etc.) to obtain the fresh air attenuation distance.

[0038] As an example, the distance from the position of the air outlet in the vehicle to the center position of the occupant in the vehicle may be a horizontal distance.

[0039] The greater the fresh air attenuation distance, the greater the attenuation of the fresh air's effectiveness, and therefore the smaller the fresh air effectiveness coefficient. In this embodiment of the present invention, the fresh air attenuation distance, and thus the fresh air effectiveness coefficient, is determined by measuring the distance from the open air outlet to the center of the occupant. This effectively quantifies the effectiveness of the fresh air from the air outlet to the occupant's breathing zone.

[0040] The effectiveness of the fresh air from the air outlet to the passenger breathing zone also meets the requirement that the effectiveness of the fresh air increases with the increase of the diameter of the air outlet. The reason is that the larger the diameter, the greater the initial momentum of the fresh air jet, which can keep the high speed of the fresh air jet for a longer time, thereby slowing down the attenuation to maintain the effectiveness of the fresh air. In addition, the effectiveness of the fresh air from the air outlet to the passenger breathing zone also meets the requirement that the effectiveness of the fresh air increases with the increase of the diameter of the air outlet. The reason is that the turbulence coefficient of the air outlet in the car is a parameter that describes the turbulent mixing intensity in the jet flow. Its value is related to the shape, surface roughness and flow characteristics of the air outlet in the car. The smaller the turbulence coefficient, the slower the fresh air decays and the greater the fresh air effectiveness coefficient.

[0041] Based on this, in some embodiments, the above step S120 further includes: The fresh air effectiveness coefficient is determined based on the turbulence coefficient of the in-vehicle air outlet and / or the diameter of the in-vehicle air outlet, wherein the fresh air effectiveness coefficient is negatively correlated with the turbulence coefficient of the in-vehicle air outlet and / or positively correlated with the diameter.

[0042] The embodiment of the present invention also determines the fresh air effectiveness coefficient based on the turbulence coefficient of the air outlet in the vehicle and / or the diameter of the air outlet in the vehicle, which is conducive to further improving the accuracy of the fresh air effectiveness coefficient.

[0043] In some embodiments, the following formula can be used to determine the fresh air effectiveness coefficient, combining the horizontal distance from the air outlet to the passenger breathing zone, the turbulence coefficient of the air outlet, and the diameter of the air outlet. (2) Where, represents the fresh air effectiveness coefficient, represents the turbulence coefficient of the air outlet inside the vehicle, Indicates the fresh air attenuation distance, Indicates the diameter of the air outlet in the car.

[0044] Optionally, the acquiring information of air pollutants inside and outside the vehicle, and determining the initial minimum fresh air introduction amount based on the information of air pollutants inside and outside the vehicle, includes: Obtaining the increasing rate of air pollutants inside the vehicle, the concentration threshold of air pollutants inside the vehicle, and the concentration of air pollutants outside the vehicle; The initial minimum fresh air introduction amount is determined based on the increase rate of the in-vehicle air pollutants, the concentration threshold of the in-vehicle air pollutants, and the concentration of the air pollutants outside the vehicle.

[0045] The above-mentioned concentration threshold of the air pollutants in the vehicle may be a preset value.

[0046] In embodiments of the present invention, the initial minimum fresh air intake amount can be determined based on a predetermined rate of increase of in-vehicle air pollutants, a threshold concentration of in-vehicle air pollutants, and a curve showing the relationship between the concentration of outside air pollutants and the initial minimum fresh air intake amount, or by a pre-established formula. Introducing fresh air based on the initial minimum fresh air intake amount can ensure that the concentration of in-vehicle air pollutants at the in-vehicle air outlet is below the threshold concentration of in-vehicle air pollutants.

[0047] The following uses a pre-built formula as an example to explain how to determine the initial minimum fresh air introduction rate.

[0048] (3) Where, is the initial minimum fresh air introduction volume, The rate of increase of air pollutants in the car, is the concentration threshold of air pollutants in the car, is the concentration of air pollutants outside the vehicle.

[0049] The embodiment of the present invention determines the initial minimum fresh air introduction amount through the above method, which is conducive to stabilizing the concentration of air pollutants in the vehicle within the concentration threshold of air pollutants.

[0050] Optionally, the air pollutants include first air pollutants generated by passengers and second air pollutants generated by vehicle interior, and determining the initial minimum fresh air introduction amount includes: determining a first minimum fresh air introduction amount based on an increase rate of the first air pollutant in the vehicle, a concentration threshold of the first air pollutant in the vehicle, and a concentration of the first air pollutant outside the vehicle; determining a second minimum fresh air introduction amount based on an increase rate of the second air pollutant in the vehicle, a concentration threshold of the second air pollutant in the vehicle, and a concentration of the second air pollutant outside the vehicle; The initial minimum fresh air introduction amount is determined based on the first minimum fresh air introduction amount and / or the second minimum fresh air introduction amount.

[0051] In this embodiment, the concentration threshold of the first air pollutant and the concentration threshold of the second air pollutant are both preset thresholds. The increase rate of the first air pollutant and the increase rate of the second air pollutant can be detected by an air quality sensor or the like or calibrated empirically. The concentration of the first air pollutant and the concentration of the second air pollutant can be detected by an air quality sensor or the like.

[0052] The first air pollutant may be carbon dioxide, and the carbon dioxide concentration threshold may be 800 ppm. Second air pollutants may include relevant air pollutants listed in the national standard GB / T27630-2011, "Guidelines for Passenger Vehicle Interior Air Quality Assessment," such as aldehydes, ketones, and benzene series. The concentration threshold for each second air pollutant may be determined in accordance with the relevant standards. Both the first and second fresh air intake rates may be determined using Formula 3 above.

[0053] In an embodiment of the present invention, air pollutants are divided into first air pollutants generated by the occupants and second air pollutants generated by the vehicle interior, and the corresponding first minimum fresh air introduction amount and second minimum fresh air introduction amount are determined respectively, thereby obtaining the above-mentioned initial minimum fresh air introduction amount, which is beneficial to improving the comprehensiveness of the initial minimum fresh air introduction amount, thereby helping to further improve the air quality in the vehicle.

[0054] In some embodiments, the sum of the first minimum fresh air introduction amount and the second minimum fresh air introduction amount can be determined as the above-mentioned initial minimum fresh air introduction amount.

[0055] In other embodiments, since the introduction of fresh air can simultaneously dilute the first air pollutants and the second air pollutants in the vehicle, in order to further reduce the energy consumption required to introduce fresh air, the maximum value of the first minimum fresh air introduction amount and the second minimum fresh air introduction amount can be determined as the above-mentioned initial minimum fresh air introduction amount.

[0056] In some embodiments, to further reduce vehicle energy consumption, the first minimum fresh air intake rate may be determined only when the concentration of a first air pollutant in the vehicle exceeds a concentration threshold of the first air pollutant; and the second minimum fresh air intake rate may be determined only when the concentration of a second air pollutant in the vehicle exceeds a concentration threshold of the second air pollutant. After the first minimum fresh air intake rate and the second minimum fresh air intake rate have been determined, the initial minimum fresh air intake rate is determined based on the sum of the first minimum fresh air intake rate and the second minimum fresh air intake rate; and after only the first minimum fresh air intake rate or the second minimum fresh air intake rate has been determined, the initial minimum fresh air intake rate is determined based only on the first minimum fresh air intake rate or the second minimum fresh air intake rate.

[0057] Optionally, determining the first minimum fresh air introduction amount includes: determining a minimum amount of fresh air introduced for a single person based on an increase rate of the first air pollutant corresponding to a single person in the vehicle, a concentration threshold of the first air pollutant in the vehicle, and a concentration of the first air pollutant outside the vehicle; The first minimum fresh air introduction amount is determined based on the product of the minimum fresh air introduction amount required for a single person and the number of occupants in the vehicle.

[0058] In this embodiment, the formula for determining the first minimum fresh air introduction amount can be constructed with reference to Formula 4, which is as follows: (4) Where, is the first minimum amount of fresh air introduced, is the number of passengers in the car, is the increase rate of the first air pollutant corresponding to a single person in the car, is the concentration threshold of the first air pollutant in the car, is the concentration of the first air pollutant outside the vehicle.

[0059] In this embodiment, the minimum amount of fresh air introduced required for one person is first determined, and then the first minimum amount of fresh air introduced is determined based on the minimum amount of fresh air introduced required for one person and the number of occupants in the vehicle, which is conducive to improving the accuracy of the first minimum amount of fresh air introduced.

[0060] Optionally, determining the second minimum fresh air introduction amount includes: determining a minimum amount of fresh air introduced for each of the second air pollutants based on an increase rate of each of the second air pollutants in the vehicle, a concentration threshold of each of the second air pollutants in the vehicle, and a concentration of each of the second air pollutants outside the vehicle; The second minimum fresh air introduction amount is determined based on the maximum value of the minimum fresh air introduction amounts required for each of the second air pollutants.

[0061] In this embodiment, the formula for determining the second minimum fresh air introduction amount can be constructed with reference to Formula 5, as follows: (5) Where, The second minimum amount of fresh air introduced, is the increasing rate of the bth second air pollutant in the car, is the concentration threshold of the bth second air pollutant in the car, is the concentration of the bth second air pollutant outside the vehicle, Can be considered as 0.

[0062] Among them, the value of the above b can be 1 to n, that is, the second air pollution can include 1 to n types, such as aldehydes, ketone pollutants and benzene series, etc. The above formula can be used to determine the maximum value of the minimum fresh air introduction amount required for n types of second air pollutants as the second minimum fresh air introduction amount.

[0063] In this embodiment, the maximum value of the minimum fresh air introduction amount required for the second air pollutant is determined as the second minimum fresh air introduction amount, rather than the cumulative value, which is beneficial to avoid high vehicle energy consumption caused by excessive fresh air introduction amount.

[0064] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.
