[0024] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. When the following description refers to the drawings, identical numerals in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application.

That is, these functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0026] The flowcharts shown in the accompanying drawings are for illustrative purposes only and do not necessarily include all contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may be decomposed, while others may be combined or partially combined. Therefore, the actual execution order may vary depending on the actual situation.

[0027] In this application, "plurality" refers to two or more. "And / or" describes the relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the related objects are in an "or" relationship.

[0028] Currently, drivers and passengers typically improve their car's interior odor by spraying perfume or using an in-car aromatherapy system. However, this method lacks controllability and cannot adjust the fragrance concentration. Furthermore, factors such as weather and climate can affect the diffusion of perfume or aromatherapy, resulting in the fragrance not meeting the driver's expectations, thus impacting the driving experience.

[0029] To this end, one aspect of this application provides a method for controlling the release of fragrance in a vehicle. Figure 1 , Figure 1 This is a flow chart of a method for controlling vehicle fragrance release, as shown in an exemplary embodiment of the present application. This control method is applied to the vehicle side and includes at least S110 to S140, which are described in detail as follows:

[0030] S110: In response to the fragrance release instruction, determine the fragrance parameters of the specified fragrance, and calculate the target release concentration of the fragrance specified in the fragrance release instruction based on the current total pressure in the vehicle, the current temperature in the vehicle, and the current humidity in the vehicle; wherein the fragrance parameters include fragrance perception intensity, fragrance release rate constant, and fragrance release amount.

[0031] A fragrance release command is a user-issued instruction for releasing a specific fragrance. This command may also carry parameters related to the specific fragrance, as well as parameters indicating the user's desired and desired time. For example, a user may send a fragrance release command to the execution subject of this embodiment via a mobile device or other user terminal, specifying a low-concentration floral fragrance. In certain embodiments, this command may also carry the user's desired vehicle use time. This allows the concentration of the fragrance released in the vehicle to meet the user's desired time of use, thereby enhancing the user experience.

[0032] Fragrance parameters are parameters related to a specific fragrance determined by the execution entity of this embodiment based on the initial parameters carried in the fragrance release instruction. For example, based on the fragrance concentration level carried in the fragrance release instruction, the execution entity of this embodiment determines the fragrance release amount corresponding to the fragrance concentration level in a preset concentration relationship table, thereby determining the relevant fragrance parameters.

[0033] In another exemplary embodiment, the fragrance release instruction carries the fragrance type, fragrance concentration level, user information, and vehicle activation time; the following describes how to determine the fragrance parameters of a specified fragrance: based on the fragrance type and fragrance concentration level, the target user's fragrance perception intensity is determined; wherein the target user is a preset user that matches the user information; based on the fragrance perception intensity and fragrance concentration level, the fragrance release amount is determined; the interval length is calculated based on the current time and the vehicle activation time; based on the interval length and the fragrance release amount, the fragrance release rate constant is determined. Fragrance types include, but are not limited to, fragrance notes and types. Fragrance concentration is a parameter related to fragrance quality and spatial volume; the higher the concentration, the higher the fragrance quality per unit spatial volume.

[0034] Specifically, the user information is matched with the preset user information to determine the target user with a successful match. The fragrance perception concentration of the target user is determined based on the preset fragrance type and preset fragrance concentration level corresponding to the target user. This parameter can personalize the perception of fragrance concentration of different users. Because different users have different olfactory sensitivities, there will be differences in the perception of the same standard concentration. Therefore, combining the user identity information can make the determined fragrance perception concentration more suitable, which is conducive to personalized fragrance control.

[0035] Before a user activates or enters a vehicle, the fragrance concentration in the vehicle must be adjusted to the user's desired concentration level. The interval duration is calculated by subtracting the vehicle activation time from the current time. This is combined with the fragrance release amount to determine the corresponding fragrance release rate constant, thereby determining the appropriate fragrance release rate. The interval duration is not necessarily equal to the release duration; the release duration can be less than or equal to the interval duration.

[0036] This embodiment considers the impact of real-time in-vehicle environmental parameters on the release of a specified fragrance, specifically considering parameters such as total in-vehicle pressure, temperature, and humidity, to ensure the accuracy of the calculated target release concentration. While prior art only considers the impact of temperature on gas concentration, this application has discovered that pressure, temperature, and humidity all significantly affect gas concentration in a confined space. Considering only one of these factors results in a less accurate calculated target release concentration. Therefore, this embodiment, while incorporating temperature, also considers the impact of in-vehicle pressure and humidity on gas release concentration, resulting in a more accurate target release concentration.

[0037] S120: Calculate the release duration of the designated fragrance according to the target release concentration, the fragrance release rate constant, and the fragrance release amount.

[0038] The target release concentration is the target concentration that needs to be achieved by releasing a specified fragrance; the fragrance release rate constant is a parameter related to the fragrance release rate, and the fragrance release amount is the total mass released to characterize the specified fragrance.

[0039] For example, the fragrance release rate is calculated based on the target release concentration and the fragrance release rate constant; the fragrance release amount is divided by the fragrance release rate to obtain the release duration of the specified fragrance. The specific formula is as follows:

[0040] t=m / r; r=K1×C; where t represents the release duration, m represents the fragrance release amount, r represents the fragrance release rate, K1 represents the fragrance release rate constant, and C represents the target release concentration.

[0041] S130: Calculate the release volume of the specified fragrance based on the fragrance perception intensity, the volume of the space inside the vehicle, the fragrance release rate constant, the fragrance release amount, and the perception intensity correction coefficient; the perception intensity correction coefficient is a constant determined based on the current total pressure inside the vehicle, the current temperature inside the vehicle, and the current humidity inside the vehicle.

[0042] For example, the fragrance perception intensity, the volume of the space inside the vehicle, and the fragrance release rate constant are multiplied to obtain a first product; the fragrance release amount and the perception intensity correction coefficient are multiplied to obtain a second product; and the quotient of the first product and the second product is used as the release volume of the specified fragrance.

[0043] The specific formula is as follows:

[0044] F = (I × V × K1) / m × K2; where I represents the fragrance perception intensity, V represents the volume of the vehicle interior, K1 represents the fragrance release rate constant, m represents the fragrance release amount, and K2 represents the perception intensity correction coefficient.

[0045] In another exemplary embodiment, the origin of the perception intensity correction coefficient is explained as follows: a point plotting operation is performed in a preset coordinate system according to the current total pressure inside the vehicle, the current temperature inside the vehicle, and the current humidity inside the vehicle to obtain a target point; the distance between the target point and each preset cluster point is calculated, and the preset coefficient corresponding to the preset cluster point with the shortest distance to the target point is used as the perception intensity correction coefficient; wherein, the preset coefficients corresponding to different preset cluster points are different.

[0046] Preset cluster points are clusters determined by plotting multiple points in a preset coordinate system based on standard or historical parameters. For example, based on the pressure, temperature, and humidity inside a vehicle at various historical moments, multiple points are plotted in a preset coordinate system to determine a clustered area. The point at the center of this clustered area is used as a cluster, and a corresponding preset coefficient is assigned to each cluster. Different clusters have different preset coefficients, which serve as the perception strength correction factor for each cluster.

[0047] By determining the three-dimensional coordinate parameters, the complex calculation process is simplified into a simple distance calculation process, which can more quickly determine the accurate perception intensity correction coefficient based on the current in-vehicle parameters.

[0048] S140: Controlling the release of the specified fragrance based on the released air volume and release duration.

[0049] The air volume represents the amount of air flowing through a specific fragrance per unit time, and is used to indicate how quickly the fragrance is released. The release duration represents the total duration of the release of the specific fragrance, i.e., the amount of air volume released during the release duration.

[0050] This embodiment responds to the fragrance release instruction to determine the fragrance parameters of the specified fragrance, and considers the current relevant environmental parameters in the car to determine the release duration and release volume of the specified fragrance, so as to determine the release parameters of the specified fragrance in real time to meet the driver and passengers' needs for the fragrance concentration in the car and provide a better experience for the driver and passengers.

[0051] In another exemplary embodiment of the present application, it is described in detail how to calculate the target release concentration of the fragrance specified in the fragrance release instruction based on the current total pressure in the car, the current temperature in the car, and the current humidity in the car. For details, please refer to Figure 2 , Figure 2 is based on Figure 1 The exemplary embodiment shown is a flow chart of another method for controlling the release of fragrance in a vehicle. Figure 1 The illustrated S110 further includes S210 to S230, which are described in detail as follows:

[0052] S210: Determine a target constant for calculating a corrected temperature based on a preset temperature range within which the current vehicle interior temperature is located.

[0053] There are multiple preset temperature intervals, and each preset temperature interval corresponds to a constant used to calculate the correction temperature. Generally, different preset temperature intervals correspond to different constants, but in some embodiments, the constants corresponding to different preset temperature intervals can be the same. This embodiment does not limit the constants corresponding to each preset temperature interval.

[0054] Exemplarily, the current vehicle interior temperature is matched with each preset temperature interval to determine the target preset temperature interval in which the current vehicle interior temperature is located, and a constant corresponding to the target preset temperature interval is used as a target constant for calculating the corrected temperature.

[0055] S220: Calculate the current corrected temperature inside the vehicle based on the target constant and the current saturated water vapor pressure inside the vehicle; wherein the current saturated water vapor pressure inside the vehicle is a pressure calculated based on the current water vapor pressure of the air inside the vehicle and the current humidity inside the vehicle.

[0056] The current saturated water vapor pressure is directly related to the current vehicle interior temperature. The higher the current temperature, the greater the current saturated water vapor pressure. The current saturated water vapor pressure can be calculated using the humidity calculation formula: RH = (p1 / p2), or p2 = p1 / RH. RH represents the current vehicle interior humidity, p1 represents the current vehicle interior air vapor pressure, and p2 represents the current vehicle interior saturated water vapor pressure.

[0057] Exemplarily, an empirical equation of the current corrected temperature inside the vehicle and the current saturated water vapor pressure inside the vehicle is constructed, and the target constant and the current saturated water vapor pressure inside the vehicle are substituted into the empirical equation to quickly calculate the current corrected temperature inside the vehicle.

[0058] S230: Calculate a target release concentration of the designated fragrance based on the current total pressure in the vehicle and the current corrected temperature in the vehicle.

[0059] Substitute the current total pressure and the current corrected temperature into the ideal gas equation to calculate the target release concentration of the specified fragrance.

[0060] This embodiment provides a method for calculating the target release concentration by directly measuring the relevant parameters: the current total pressure in the vehicle, the current temperature in the vehicle, and the current humidity in the vehicle, to quickly calculate the target release concentration of the fragrance specified in the fragrance release instruction.

[0061] In another exemplary embodiment of the present application, S220 and S230 are described in detail. Figure 3 , Figure 3 is based on Figure 2The exemplary embodiment shown is a flow chart of another method for controlling the release of fragrance in a vehicle. Figure 2 The illustrated S220 further includes S310 to S320, and S230 further includes S330, which are described in detail as follows:

[0062] S310: Constructing a relationship function between the current saturated water vapor pressure in the vehicle and the current temperature in the vehicle, and differentiating the relationship function to obtain a derivative relationship function; wherein the derivative relationship function includes a constant to be determined.

[0063] S320: Substitute the target constant into the derivative relationship function to calculate the current corrected temperature inside the vehicle.

[0064] S330: Divide the current total pressure in the vehicle by the product of the current corrected temperature in the vehicle and the universal gas constant, and use the calculated quotient as the target release concentration of the specified fragrance.

[0065] This embodiment is exemplified as follows: Based on the similar proportional relationship between the current corrected temperature in the vehicle and the current saturated water vapor pressure in the vehicle, the empirical equation is constructed: d(lnp2) / d(lnT1)=L / R×T1 2 , which is the relationship function in this embodiment; where p2 represents the current saturated water vapor pressure in the vehicle, T1 represents the current corrected temperature in the vehicle, L represents the heat of evaporation, and R represents the universal gas constant. Derivatively, we obtain ln(p2) = -L / R*1 / (T1+273.15)+M; where M represents the integral constant, which is the reciprocal relationship function in this embodiment. Using the formula recommended by Emanuel, we obtain:

[0066] ln(p2)=A-(B / (T1+C))=8.10765-(1750.286) / (T1+235); where A, B, and C are

[0067] The target constant can be determined according to the preset constant table shown in Table 1: the current vehicle interior temperature T is matched with the preset temperature range, and the constant corresponding to the successfully matched preset temperature range is used as the target constant.

[0068] T1=((1750.286-235*(8.10765-lnp2)) / (8.10765-lnp2);

[0069] T1=((1750.286-235*(8.10765-ln(p1 / RH))) / (8.10765-ln(p1 / RH)); where RH is

[0070] Indicates the current humidity in the car, and p1 indicates the current water vapor pressure of the air in the car.

[0071] Table 1: Preset constant determination table

[0072]

[0073] PV = nRT1; where P represents the current vehicle interior pressure, V represents the interior volume, n represents the amount of substance, R represents the universal gas constant, T1 represents the current corrected interior temperature, and R is 8.31 J / (mol*K). C represents the target release concentration. The target release concentration equation is calculated as: C = n / V = P / RT1.

The exemplary description is as follows:

[0076] The controller 300 determines the fragrance parameters of the specified fragrance in response to the fragrance release instruction, and calculates the target release concentration of the fragrance specified in the fragrance release instruction based on the current total pressure in the vehicle, the current temperature in the vehicle, and the current humidity in the vehicle; wherein the fragrance parameters include fragrance perception intensity, fragrance release rate constant, and fragrance release amount; the controller 300 calculates the release duration of the specified fragrance based on the target release concentration, fragrance release rate constant, and fragrance release amount; the controller 300 calculates the release air volume of the specified fragrance based on the fragrance perception intensity, the volume of the space in the vehicle, the fragrance release rate constant, the fragrance release amount, and the perception intensity correction coefficient; wherein the perception intensity correction coefficient is a constant determined based on the current total pressure in the vehicle, the current temperature in the vehicle, and the current humidity in the vehicle; the controller 300 controls the release of the specified fragrance based on the release air volume and release duration.
