For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the related objects are in an "or" relationship.

[0028] At present, the way for drivers and passengers to improve the smell in the car is generally to spray perfume in the car or set up car aromatherapy. Obviously, this method cannot adjust the concentration of the fragrance and has poor controllability. At the same time, factors such as weather and climate will also affect the diffusion of perfume or aromatherapy, resulting in the fragrance failing to meet the expectations of drivers and passengers, thus affecting the driving experience of drivers and passengers.

[0029] To this end, one aspect of the present 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 the release of fragrance in a vehicle, shown in an exemplary embodiment of the present application. The 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 according to 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] The fragrance release instruction is an instruction issued by the user to release a specified fragrance. The instruction may also carry parameters related to the specified fragrance, as well as parameters that characterize the user's related expectations and related time. For example, a user sends a fragrance release instruction to the execution subject of this embodiment through a user terminal such as a mobile phone terminal. The instruction specifies that the fragrance type is a floral fragrance with a low concentration. In some embodiments, the instruction also carries the time when the user expects to use the car, so as to control the concentration of the fragrance released in the car to meet the user's expectations before the time when the user expects to use the car, so as to improve the user's experience.

[0032] The fragrance parameters are parameters related to the specified fragrance determined by the execution subject of this embodiment based on the initial parameters carried in the fragrance release instruction. For example, the execution subject of this embodiment determines the fragrance release amount corresponding to the fragrance concentration level in the preset concentration relationship table according to the fragrance concentration level carried in the fragrance release instruction, that is, determines 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; how to determine the fragrance parameters of the specified fragrance is explained: according to the fragrance type and fragrance concentration level, the fragrance perception intensity of the target user is determined; wherein the target user is a preset user matching the user information; according to the fragrance perception intensity and fragrance concentration level, the fragrance release amount is determined; according to the current time and the vehicle activation time, the interval length is calculated; according to the interval length and the fragrance release amount, the fragrance release rate constant is determined. Among them, the fragrance type includes but is not limited to the fragrance note and type. The fragrance concentration is a parameter related to the fragrance quality and space volume. The higher the concentration, the higher the fragrance quality per unit space volume.

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

[0035] Before the user activates or enters the vehicle, the fragrance concentration in the vehicle needs to be adjusted to the user's desired concentration value, that is, to achieve the fragrance concentration level expected by the user. The vehicle activation time is subtracted from the current time to calculate the interval time, and combined with the fragrance release amount, the corresponding fragrance release rate constant is determined to determine the appropriate fragrance release rate. The interval time is not necessarily equal to the release time, and the release time is less than or equal to the interval time.

[0036] This embodiment considers the impact of real-time relevant environmental parameters in the car on the release of the specified fragrance, specifically considering parameters such as total pressure, temperature, and humidity in the car to ensure the accuracy of the calculated target release concentration. The prior art only considers the impact of temperature on gas concentration. This application finds that pressure, temperature, and humidity all have a relatively obvious impact on the gas concentration in a confined space. If only one of them is considered, the accuracy of the calculated target release concentration is low. For this reason, this embodiment introduces the temperature parameter while also considering the impact of pressure and humidity in the car on the gas release concentration, so that the determined target release concentration is more accurate.

[0037] S120: Calculate the release time 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 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 a parameter that characterizes the total mass released by 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 and the fragrance release rate are divided to obtain the release time of the specified fragrance. The specific formula is as follows:

[0040] t=m / r;r=K 1 ×C; where t represents the release duration, m represents the fragrance release amount, r represents the fragrance release rate, and K 1 represents the fragrance release rate constant, and C represents the target release concentration.

[0041] S130: Calculate the release volume of the specified fragrance according to 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; wherein the perception intensity correction coefficient is a constant determined according to the current total pressure inside the vehicle, the current temperature inside the vehicle, and the current humidity inside the vehicle.

[0042] Exemplarily, 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; the quotient of the first product and the second product is used as the release air volume of the specified fragrance.

[0043] The specific formula is as follows:

[0044] F=(I×V×K 1 ) / m×K 2 ; Where I represents the fragrance perception intensity, V represents the volume of the interior space, and K 1 represents the fragrance release rate constant, m represents the fragrance release amount, K2 Represents the perceived intensity correction factor.

[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] The preset clustering points are clusters determined by drawing multiple points in a preset coordinate system based on standard parameters or historical parameters. For example, based on the pressure, temperature, and humidity in the car at various historical moments, multiple points are drawn in a preset coordinate system to determine the clustering area, and the point at the center of the clustering area is used as the clustering cluster, and the corresponding preset coefficient is corresponded to it, so that different clustering clusters correspond to different preset coefficients, and the preset coefficient is the perception intensity correction coefficient corresponding to each clustering 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 a specified fragrance based on the released air volume and the release duration.

[0049] The air volume released represents the flow rate of the specified fragrance gas per unit time, and is used to represent the release speed of the specified fragrance. The release duration represents the total duration of releasing the specified fragrance, that is, the specified fragrance is released with the air volume released within 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 the driver and passengers with a better experience.

[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 according to the current total pressure in the vehicle, the current temperature in the vehicle, and the current humidity in the vehicle. 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 S110 shown further includes S210 to S230, which are described in detail as follows:

[0052] S210: Determine a target constant for calculating a corrected temperature according to a preset temperature range in which the current temperature inside the vehicle is located.

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

[0054] Exemplarily, the current temperature inside the vehicle is matched with each preset temperature interval to determine the target preset temperature interval in which the current temperature inside the vehicle is located, and a constant corresponding to the target preset temperature interval is used as a target constant for calculating the correction 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 temperature inside the vehicle. The higher the current temperature, the greater the current saturated water vapor pressure. The current saturated water vapor pressure can be calculated according to the humidity calculation formula: RH = (p 1 / p 2 ), that is, p 2 =p 1 / RH; RH represents the current humidity in the car, p 1 Indicates the current water vapor pressure in the car, p 2 Indicates the current saturated water vapor pressure in the car.

[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 the 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 in the vehicle and the current corrected temperature in the vehicle 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 car, the current temperature in the car, and the current humidity in the car, 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 2 The exemplary embodiment shown is a flow chart of another method for controlling the release of fragrance in a vehicle. Figure 2 The S220 shown 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 taking the derivative of 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 designated fragrance.

[0065] This embodiment is exemplarily described 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, an empirical equation is constructed: d(lnp 2 ) / d(lnT 1 )=L / R×T 1 2 , which is the relationship function in this embodiment; where p 2 Indicates the current saturated water vapor pressure in the car, T 1 represents the current corrected temperature in the car, L represents the evaporation heat, and R represents the universal gas constant. 2 )=-L / R*1 / (T 1 +273.15)+M; wherein M represents an integral constant, that is, the reciprocal relationship function in this embodiment is obtained, and the formula recommended by Emanuel is used to obtain:

[0066] ln(p 2 )=A-(B / (T 1 + C)) = 8.10765 - (1750.286) / (T 1 +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] T 1=((1750.286-235*(8.10765-lnp 2 )) / (8.10765-lnp 2 );

[0069] T 1 =((1750.286-235*(8.10765-ln(p 1 / RH))) / (8.10765-ln(p 1 / RH)); RH stands for

[0070] Displays the current humidity in the car, p 1 Indicates the current water vapor pressure of the air in the car.

[0073] PV=nRT 1 ; Where P represents the current pressure inside the car, V represents the volume of the space inside the car, n represents the amount of substance, R represents the universal gas constant, T 1 represents the current corrected temperature in the vehicle, the value of R is 8.31 J / (mol*K), and C represents the target release concentration. The calculation formula of the target release concentration equation is further obtained: C = n / V = P / RT 1 .

[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 according to 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 according to the target release concentration, fragrance release rate constant, and fragrance release amount; the controller 300 calculates the release air volume of the specified fragrance according to 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 according to 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 the release duration.
