[0036] See also Figure 2 , Figure 2 is a flow chart of a sunroof adjustment method shown in an exemplary embodiment of the present application. The method can be applied to Figure 1 The implementation environment shown is as follows. The method may also be applicable to other exemplary implementation environments and be specifically executed by devices in other implementation environments. This embodiment does not limit the implementation environment to which the method is applicable.

[0037] like Figure 2 As shown, in an exemplary embodiment, the sunroof adjustment method includes at least steps S210 to S240, which are described in detail as follows:

[0038] Step S210, obtaining environmental information and vehicle information, the environmental information includes the current wind speed, and the vehicle information includes the current vehicle speed and the current sunroof opening angle.

[0039] In one embodiment of the present application, adjusting the sunroof based on environmental information and vehicle information includes: adjusting the sunroof based on rainfall detection, adjusting the sunroof based on temperature sensing, and adjusting the sunroof based on vehicle speed and wind speed. Adjusting the sunroof based on rainfall detection includes real-time monitoring of the current rainfall through a sunlight, rainfall, and humidity sensor, automatically closing the sunroof or preventing the sunroof from opening when the rainfall exceeds a preset threshold, and grading the processing according to the rainfall size, keeping the sunroof slightly open in light rainfall and completely closed in heavy rain. Adjusting the sunroof based on temperature sensing includes obtaining the real-time temperature inside the vehicle and the temperature outside the vehicle through temperature sensors inside and outside the vehicle, thereby obtaining the temperature difference between the inside and outside of the vehicle, and determining the adjustment value of the sunroof based on a preset temperature difference range. Adjusting the sunroof based on vehicle speed and wind speed includes obtaining the current vehicle speed and the current wind speed based on a vehicle speed sensor and a wind speed sensor, calculating the current wind noise and the current wind resistance based on the current vehicle speed and the current wind speed, and calculating the adjustment value of the sunroof based on the current wind noise to prevent excessive wind noise or uncomfortable airflow.

[0040] In one embodiment of the present application, the sunroof is adjusted based on rain detection, based on temperature sensing, and based on vehicle speed and wind speed according to the set priority, wherein the sunroof adjustment based on rain detection is the highest priority, the sunroof adjustment based on vehicle speed and wind speed is the middle priority, and the sunroof adjustment based on temperature sensing is the lowest priority. In this embodiment, if the sunroof responds to the highest priority sunroof adjustment based on rain detection, such as controlling the sunroof to be closed, the sunroof will no longer respond to the middle priority sunroof adjustment based on vehicle speed and wind speed and the lowest priority sunroof adjustment based on temperature sensing. If the sunroof responds to the middle priority sunroof adjustment based on vehicle speed and wind speed, it will no longer respond to the lowest priority sunroof adjustment based on temperature sensing.

[0041] In one embodiment of the present application, the vehicle first adjusts the sunroof based on rain detection, including: detecting the current rain and obtaining the current rain status based on the comparison result between the current rain and the preset rain threshold; if the current rain is heavy, the sunroof is closed and no longer responds to subsequent low-priority sunroof adjustments (i.e., sunroof adjustments based on vehicle speed and wind speed and sunroof adjustments based on temperature sensing); if the current rain is within an acceptable range, the sunroof is half opened (the second sunroof adjustment value in this embodiment is half of the maximum sunroof opening angle), and no longer responds to subsequent low-priority sunroof adjustments; if the current rain is light or there is no rain, the current sunroof opening angle is maintained and waits for subsequent low-priority sunroof adjustments.

[0042] In one embodiment of the present application, the vehicle secondly adjusts the sunroof based on the vehicle speed and wind speed, including: if the current wind speed is small or there is no rain, then after maintaining the current sunroof opening angle, a comfort index parameter is obtained based on the current wind noise and the current wind resistance; if the comfort index parameter is not within the preset comfort index range, it means that the wind noise has a large impact at this time, and the sunroof needs to be adjusted based on the first sunroof adjustment value, and no longer responds to subsequent low-priority sunroof adjustments (i.e., sunroof adjustments based on temperature sensing); if the comfort index parameter is within the preset comfort index range, it means that the wind noise has a small impact at this time, and the current sunroof opening angle is maintained, waiting for subsequent low-priority sunroof adjustments.

[0043] In one embodiment of the present application, the vehicle finally adjusts the sunroof based on temperature sensing, including: if the comfort index parameter is within a preset comfort index range, after maintaining the current sunroof opening angle, detecting the temperature inside and outside the vehicle, and obtaining a third sunroof adjustment value based on the temperature inside and outside the vehicle, and controlling the sunroof based on the third sunroof adjustment value.

[0044] In one embodiment of the present application, the priority of various sunroof adjustments for the vehicle can be customized and modified according to user needs. For example, if the user believes that wind resistance and wind noise have a greater impact, the priority of sunroof adjustment based on vehicle speed and wind speed can be set to the highest. If the user believes that the temperature difference in the vehicle has a greater impact on the sunroof adjustment, the priority of sunroof adjustment based on temperature sensing can also be set to the highest. The order in which the vehicle adjusts the sunroof changes based on the priority set by the user.

[0045] In one embodiment of the present application, after obtaining environmental information and vehicle information, it also includes: comparing the current rainfall with a preset rainfall threshold, the environmental information includes the current rainfall; if the current rainfall is less than the preset first rainfall threshold, controlling the sunroof to adjust the sunroof based on the first sunroof adjustment value; if the current rainfall is greater than or equal to the preset first rainfall threshold, and the current rainfall is less than the preset second rainfall threshold, controlling the sunroof to adjust the sunroof based on the preset second sunroof adjustment value; if the current rainfall is greater than or equal to the preset second rainfall threshold, the sunroof is closed.

[0046] In one embodiment of the present application, the first rainfall threshold is preset to be 3mm, and the second rainfall threshold is preset to be 10mm. When the current rainfall is greater than or equal to 10mm, the rainfall is large at this time, the sunroof of the vehicle is closed, and the sunroof is prevented from opening, and the sunroof adjustment based on the vehicle speed and wind speed is no longer responded, that is, the sunroof adjustment value of the first sunroof is not responded to. When the current rainfall is less than 10mm and greater than or equal to 3mm, the rainfall is within the acceptable range, and the sunroof is controlled to be adjusted based on the preset second sunroof adjustment value. In this embodiment, the preset second sunroof adjustment value can be set to half of the maximum sunroof angle of the sunroof, that is, when the current rainfall is less than 10mm and greater than or equal to 3mm, the sunroof is controlled to open half of the window, and the sunroof adjustment based on the vehicle speed and wind speed is no longer responded, that is, the sunroof adjustment value of the first sunroof is not responded to. When the current rainfall is less than 3mm, it means that there is basically no rain or the rainfall is small at this time. At this time, the sunroof adjustment will not be performed based on rainfall detection, and the sunroof adjustment can be performed based on the vehicle speed and wind speed or based on temperature sensing.

[0047] Step S220, input the current vehicle speed, current wind speed and current sunroof opening angle into a preset wind resistance prediction model to obtain the current wind resistance, and input the current wind speed and current sunroof opening angle into a preset wind noise prediction model to obtain the current wind noise.

[0048] In one embodiment of the present application, the current vehicle speed, the current wind speed and the current sunroof opening angle are input into a preset wind resistance prediction model to obtain the current wind resistance including:

[0049] WindResistanceFactor=

[0050] 0.5×ρ×CarSpeed×WindSpeed×WindowArea×

[0051] WindowCoefficient(WindowAngle) formula (1)

[0052] In formula (1), WindResistanceFactor is the current wind resistance, ρ is the preset air density, CarSpeed ​​is the current vehicle speed, WindSpeed ​​is the current wind speed, WindowArea is the sunroof area, WindowCoefficient is the preset function, and WindowAngle is the current sunroof opening angle.

[0053] In one embodiment of the present application, the current wind speed is obtained from environmental information, the current vehicle speed and the current sunroof opening angle are obtained from vehicle information, the sunroof area is obtained based on the sunroof hardware parameters of the vehicle itself, and the preset air density is a preset value based on the actual air density.

[0054] In one embodiment of the present application, the preset function WindowCoefficient (WindowAngle) is a function that calculates the resistance and noise coefficients according to the sunroof opening angle, which can be specifically expressed as: WindowCoefficient (WindowAngle) = a·sin (b·WindowAngle + c), where a is a preset proportional coefficient, which represents the intensity amplification effect of the sinusoidal function relationship between wind resistance or wind noise and the sunroof opening angle. In this embodiment, a reflects the overall influence of the shape, material and surrounding environment of the sunroof on the contribution of wind resistance or wind noise. b is a preset slope coefficient, which represents the sensitivity of the sunroof angle change to wind resistance or wind noise. When the sunroof opening angle is relatively small, the b value affects the speed of change of wind resistance or wind noise. c is a preset phase shift coefficient, which represents the starting point of the relationship between the sunroof angle and wind resistance or wind noise. In some cases, even if the sunroof is completely closed, there will be a certain amount of basic wind noise or wind resistance, and the c value reflects this initial condition. WindowAngle is the current sunroof opening angle, which is obtained from the vehicle information.

[0055] In one embodiment of the present application, the current wind speed and the current sunroof opening angle are input into a preset wind noise prediction model, and the current wind noise is obtained including:

[0056] WindNoise=

[0057] α×WindSpeed×WindowArea×(WindowCoefficient(WindowAngle)) β

[0058] Formula (2)

[0059] In formula (2), WindNoise is the current wind noise, α is the preset first wind noise coefficient, WindSpeed ​​is the current wind speed, WindowArea is the skylight area of ​​the skylight, WindowCoefficient is a preset function, WindowAngle is the current skylight opening angle, and β is the preset second wind noise coefficient.

[0060] In one embodiment of the present application, the current sunroof opening angle is obtained from vehicle information, the sunroof area is obtained according to the sunroof hardware parameters of the vehicle itself, and the first wind noise coefficient α is preset as the basic wind noise coefficient. This coefficient is related to the aerodynamic characteristics of the vehicle. For different models, α can vary in the range of 1 to 10, and this value is usually preset to be smaller. The second wind noise coefficient β is preset as the window coefficient index. This window coefficient index reflects the sensitivity of the window opening angle to the wind noise. The value of β can be between 1 and 3, where β=1 means that the wind noise is proportional to the window coefficient, and β>1 means that the wind noise is more sensitive to the window coefficient, that is, a slight change in the window angle may lead to a significant increase in wind noise.

[0061] Step S230, assign index weights to the current wind noise and the current wind resistance respectively, and obtain comfort index parameters based on the assigned index weights and the current wind resistance and the current wind noise. If the comfort index parameters are not within the preset comfort index range, the first skylight adjustment value is obtained based on the current vehicle speed and the current wind noise.

[0062] In one embodiment of the present application, the calculation formula of the comfort index parameter is as follows:

[0063] ComfortMetric =(a' * WindResistanceFactor)+(b' * WindNoise) Formula (3)

[0064] In formula (3), ComfortMetric represents the comfort index parameter, a' is the preset wind resistance index weight, a' represents the weight of the influence of wind resistance on the comfort index, WindResistanceFactor is the current wind resistance, b' is the preset wind noise index weight, b' represents the weight of the influence of wind noise on the comfort index, and WindNoise is the current wind noise. Wherein a' and b' and the preset value range are obtained according to the user's personal preference or survey to improve the user experience.

[0065] In one embodiment of the present application, the comfort index parameter is in the range of 0-100, 0-30 is the comfort zone, 31-70 is the acceptable zone, and 71-100 is the discomfort zone. When the comfort index parameter exceeds the acceptable zone, that is, the comfort index parameter is outside the range of 0-70, the first sunroof adjustment value is obtained based on the current vehicle speed and the current wind noise to realize automatic conditional sunroof to prevent excessive wind noise or uncomfortable airflow.

[0066] In one embodiment of the present application, a smaller tolerance interval (for example, ±10% of the comfort index parameter) is set based on the preset comfort index range. Only when the comfort index exceeds the tolerance interval, the skylight is adjusted based on the first skylight adjustment value, thereby reducing unnecessary adjustments caused by slight changes in the environment.

[0067] In one embodiment of the present application, when it is detected that the comfort index parameter exceeds the preset comfort index range or exceeds the tolerance interval, the sunroof adjustment is not immediately performed based on the first sunroof adjustment value. After waiting for a preset waiting time (such as 10 seconds), the comfort index parameter is detected again to see whether it exceeds the preset comfort index range or exceeds the tolerance interval. If it is still greater than or exceeds, the sunroof adjustment is performed based on the first sunroof value, thereby preventing excessive adjustment caused by short-term fluctuations in the comfort index parameter.

[0068] In one embodiment of the present application, obtaining the first skylight adjustment value based on the current vehicle speed and the current wind noise includes: obtaining the wind noise level based on the current wind noise conversion; calculating the first skylight adjustment value by weighted summing the current vehicle speed and a preset vehicle speed adjustment weight, the wind noise level and the preset wind noise adjustment weight; calculating a scaling factor based on the maximum skylight opening angle of the skylight, the minimum skylight opening angle of the skylight, a preset vehicle speed range and a preset wind noise level range; scaling the first skylight adjustment value based on the scaling factor, and controlling the sunroof to perform skylight adjustment based on the scaled first skylight adjustment value.

[0069] In one embodiment of the present application, the calculation formula of the first daylight adjustment value is as follows:

[0070] AdjustmentValue=(w V ·V+w N ·N)·ScalingFactor Formula (4)

[0071] In formula (4), AdjustmentValue is the first daylight adjustment value, w V is the preset speed adjustment weight, V is the current speed, w N is the preset wind noise adjustment weight, N is the wind noise level, and ScalingFactor is the scaling factor.

[0072] In one embodiment of the present application, the wind noise level is calculated based on the current wind noise and includes: N = N_{norm}-N_{min} / N_{max}-N_{min}, where N is the wind noise level, N_{norm} is the current wind noise, N_{min} is the preset minimum wind noise value, and N_{max} is the preset maximum wind noise value.

[0073] In one embodiment of the present application, the range of wind noise is (N_{min}) to (N_{max}), and the range of vehicle speed is (V_{min}) to (V_{max}), where N_{min} is the preset minimum wind noise value, N_{max} is the preset maximum wind noise value, V_{min} is the preset minimum vehicle speed value, and V_{max} is the preset maximum vehicle speed value. In this embodiment, the wind noise range and vehicle speed range can be preset according to different vehicle configurations and different vehicle model designs.

[0074] In one embodiment of the present application, calculating the scaling factor based on the maximum sunroof opening angle of the sunroof, the minimum sunroof opening angle of the sunroof, the preset vehicle speed range and the preset wind noise level range includes: performing weighted sum calculation on the preset vehicle speed adjustment weight and the preset vehicle speed maximum value, the preset wind noise adjustment weight and the preset wind noise maximum value to obtain the maximum weighted sum; performing weighted sum calculation on the preset vehicle speed adjustment weight and the preset vehicle speed minimum value, the preset wind noise adjustment weight and the preset wind noise minimum value to obtain the minimum weighted sum; and obtaining the scaling factor based on the difference between the maximum sunroof opening angle and the minimum sunroof opening angle, and the ratio of the difference between the maximum weighted sum and the minimum weighted sum.

[0075] In one embodiment of the present application, the maximum weighted sum is w V ·V max +w N ·N max , the minimum weighted sum is w V ·V min +w N ·N min , where w V is the preset vehicle speed adjustment weight, V max is the preset maximum vehicle speed, w N is the preset wind noise adjustment weight, N max is the preset maximum wind noise value. The minimum weighted sum is w V ·V min +w N ·N min , where w V is the preset vehicle speed adjustment weight, V min is the preset minimum vehicle speed, w N is the preset wind noise adjustment weight, N min The preset minimum wind noise value.

[0076] In one embodiment of the present application, the calculation formula of the scaling factor is as follows:

[0077]

[0078] In formula (5), ScalingFactor is the scaling factor, T max is the maximum sunroof opening angle, T min is the minimum sunroof opening angle, w V is the preset vehicle speed adjustment weight, V max is the preset maximum vehicle speed, w N is the preset wind noise adjustment weight, N max is the preset maximum wind noise value, V min is the preset minimum speed, N min It is the preset minimum value of wind noise, where the maximum sunroof opening angle and the minimum sunroof opening angle are obtained based on the sunroof hardware parameters of different models.

[0079] In one embodiment of the present application, after obtaining the comfort index parameter, it also includes: if the comfort index parameter is within a preset comfort index range, then obtaining the temperature difference between inside and outside the car based on the temperature inside the car and the temperature outside the car, and the environmental information also includes the temperature inside the car and the temperature outside the car; if the temperature difference between inside and outside the car is within the preset temperature difference range, then obtaining a temperature difference adjustment coefficient based on the temperature difference between inside and outside the car and the preset temperature difference range; obtaining a third sunroof adjustment value based on the temperature difference adjustment coefficient and the maximum sunroof opening angle of the sunroof, and controlling the sunroof for sunroof adjustment according to the third sunroof adjustment value.

[0080] In one embodiment of the present application, the temperature inside and outside the car is obtained by temperature sensors inside and outside the car, and the temperature difference between the inside and outside of the car is calculated based on the temperature inside and outside of the car. In this embodiment, the temperature difference between the inside and outside of the car is the absolute value of the difference between the inside and outside temperature. The temperature difference between the inside and outside of the car is compared with a preset temperature difference range (which can be set to 0 to 5°C). If the temperature difference between the inside and outside of the car is outside the preset temperature difference range, the sunroof is adjusted based on user instructions. If the temperature difference between the inside and outside of the car is within the preset temperature difference range, the sunroof is controlled to be adjusted based on the third sunroof adjustment value.

[0081] In one embodiment of the present application, obtaining a third sunroof adjustment value based on the temperature difference adjustment coefficient and the maximum sunroof opening angle of the sunroof includes proportionally calculating a value between 0 and 1 as the temperature adjustment coefficient based on the position of the temperature difference between inside and outside the vehicle relative to a preset temperature difference range, and then multiplying the temperature adjustment coefficient by the maximum sunroof opening angle to determine the third sunroof adjustment value to obtain the specific angle at which the sunroof opens.

[0082] In one embodiment of the present application, when the temperature difference between inside and outside the vehicle is exactly equal to the upper limit of the preset temperature difference range, the sunroof will open to the maximum angle; as the temperature difference between inside and outside the vehicle gradually approaches the center point of the preset temperature difference range, the opening angle of the sunroof will gradually decrease; when the temperature difference between inside and outside the vehicle is 0, the opening angle of the sunroof is also 0 (completely closed).

[0083] In one embodiment of the present application, the third sunroof adjustment value is calculated as follows:

[0084] A=min(max((T_d+T_c) / (2*T_c),0),1)*A_max Formula (6)

[0085] In formula (6), A is the third sunroof adjustment value, T_d is the temperature difference between the inside and outside of the vehicle, T_c is the upper limit of the preset temperature difference range, and A_max is the maximum sunroof opening angle. In formula (6), the value of (T_d+T_c) / (2*T_c) is first calculated and limited to the range of [0,1] to obtain the temperature adjustment coefficient, and then the temperature adjustment coefficient is multiplied by A_max to obtain the third sunroof adjustment value. The third sunroof adjustment value is the angle that the sunroof should be adjusted.

[0086] Step S240: controlling the sunroof to adjust the sunroof based on the first sunroof adjustment value.

[0087] In one embodiment of the present application, the angle to which the sunroof should be adjusted is calculated according to the first adjustment value, and a linear interpolation method may be used, and the calculation is as follows:

[0088]

[0089] In formula (7), SkylightAngle is the angle to which the skylight should be adjusted, T min is the minimum sunroof opening angle, AdjustmentValue is the first adjustment value, MaxAdjustmentValue is the preset maximum adjustment value, and the preset maximum adjustment value is the maximum value that the first adjustment value may reach, which is used to ensure that the calculated sunroof angle is within the valid range, T max The maximum sunroof opening angle.

[0090] In one embodiment of the present application, the angle of the skylight is adjusted to SkylightAngle, thereby achieving skylight adjustment by controlling the skylight based on the first adjustment value.

[0091] In one embodiment of the present application, if T max is 90°, T min is 0°, w V 0.01 (for every 1km / h increase in vehicle speed, the first skylight adjustment value increases by 0.01), w Nis 0.1 (the first skylight adjustment value increases by 0.1 for every unit increase in wind noise level), ScalingFacto is 10, and the current vehicle speed is 80 km / h, the calculated wind noise level is 5, then the first skylight adjustment value is calculated as: AdjustmentValue = (0.01·80+0.1·5)·10 = (0.8+0.5)·10 = 1.3·10 = 13; then the sunroof angle adjusted based on the first skylight adjustment value is: SkylightAngle = 0+13 / MaxAdjustmentValue·(90-0), wherein MaxAdjustmentValue needs to be determined according to specific parameters and vehicle conditions. Assuming that MaxAdjustmentValue is 100 (this is just an example value, the actual value needs to be determined through experiments), the sunroof angle adjusted based on the first sunroof adjustment value is: SkylightAngle=0+13 / 100·(90-0)=11.7, that is, when the vehicle speed is 80km / h and the wind noise level is 5, the sunroof should be adjusted to an angle of approximately 11.7 degrees.
