Description

Technical Field

[0001] The present application relates to the technical field of vehicle detection, and particularly to a method, device, electronic device and storage medium for determining window defogging. Background Art

[0002] Currently, window fogging refers to the phenomenon that water vapor condenses on the window surface due to differences in temperature, humidity, etc. inside and outside the vehicle, forming water mist. The water mist formed on the window surface easily affects the driver's vision and judgment of driving conditions, thereby affecting the driving safety of the vehicle. Therefore, window defogging is required when the window is fogged.

[0003] However, a part of the traditional method relies on the user to manually turn on the defogging function, resulting in a reaction lag; another part only judges whether the window is fogged through a single humidity or temperature difference. This judgment method using a single sensor is easily affected by the environment, with a low accuracy rate. Moreover, after the single sensor determines that the vehicle needs to be defogged, the in-vehicle defogging device needs to keep running all the time, resulting in a large energy consumption of the defogging device and poor accuracy.

[0043] In order to better understand the technical solutions provided by the embodiments of this specification, the technical solutions of the embodiments of this specification will be described in detail below through the accompanying drawings and specific embodiments. It should be understood that the specific features in the embodiments of this specification and the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. Without conflict, the technical features in the embodiments of this specification and the embodiments may be combined with each other.

Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

The term "more than two" includes two or more than two.

[0045] First, the applicable application scenarios of the present application are introduced. The embodiments provided by the present application are applicable to the field of vehicle control technology.

[0046] Currently, a part of the traditional method relies on the user to manually turn on the defogging function, resulting in a reaction lag; another part only judges whether the window is fogged by a single humidity or temperature difference. This judgment method of a single sensor is vulnerable to environmental interference, with a low accuracy rate. Moreover, after the single sensor determines that the vehicle needs to be defogged, the in-vehicle defogging device needs to keep running all the time, which leads to a large energy consumption of the defogging device and poor accuracy.

[0047] The traditional method of judging vehicle defogging only through a single humidity or temperature difference is extremely susceptible to interference from the external environment, such as the heat radiation from the engine compartment and sudden humidity changes caused by heavy rain.

[0048] Based on this, the embodiments of the present application provide a method, device, electronic device, and storage medium for determining window defogging. The embodiments provided by the present application solve the technical problems in the prior art that the judgment method of a single sensor is susceptible to environmental interference, with low accuracy, which in turn affects the energy consumption and accuracy of the in-vehicle defogging device during defogging.

[0049] Figure 1 It is a flowchart of a method for determining window defogging provided by an embodiment of the present application. As Figure 1 shown, the method for determining window defogging includes the following steps:

[0050] S101. Based on the in-vehicle environmental parameters of the vehicle in the current environment, determine the dew point temperature inside the vehicle, where the in-vehicle environmental parameters include in-vehicle temperature parameters, in-vehicle humidity parameters, and in-vehicle sunlight intensity parameters.

[0051] It should be noted that the embodiments provided by the present application collect the in-vehicle environmental parameters of the vehicle in the current environment through different types of sensors in real time. After collection, the in-vehicle environmental parameters collected by the above sensors are filtered to remove noise in the data, and the dew point temperature inside the vehicle is determined through the in-vehicle temperature parameters and in-vehicle humidity parameters among the above in-vehicle environmental parameters.

[0052] It can be understood that the in-vehicle temperature parameters in the embodiments provided by the present application can be collected using an in-vehicle temperature sensor. The in-vehicle temperature sensor provided by the embodiments of the present application can be a high-precision thermocouple or an infrared sensor, which is used to monitor temperature changes in real time. In some embodiments, the accuracy of the in-vehicle temperature sensor can be 0.5 °C.

[0053] The in-vehicle humidity parameters in the embodiments provided by the present application can be collected using an in-vehicle humidity sensor. The in-vehicle humidity sensor provided by the embodiments of the present application can be a capacitive or resistive humidity sensor. In some embodiments, the accuracy of the in-vehicle humidity sensor can be 2% RH.

[0054] The sunlight intensity parameters in the embodiments provided by the present application can be collected using a sunlight sensor. The sunlight sensor provided by the embodiments of the present application can be a photosensitive element or an infrared sensor, which is used to detect the sunlight intensity of the external environment in real time and judge the influence of solar radiation on the in-vehicle temperature parameters.

[0055] Here, the sunlight intensity parameters in the embodiments provided by the present application are combined with the in-vehicle temperature parameters and in-vehicle humidity parameters to correct the dew point temperature inside the vehicle, realizing the prediction of the risk of window fogging.

[0056] Among them, the method for filtering the in-vehicle environment parameters provided in the embodiments of the present application can be customarily selected according to different application scenarios and usage conditions.

[0057] In some embodiments, the in-vehicle environment parameter filtering method can, but is not limited to, using a Kalman Filter (KF) to filter the noise in the in-vehicle environment parameters.

[0058] S102. Determine whether to turn on the in-vehicle air conditioner to defog the window based on the dew point temperature, the in-vehicle temperature parameter, and a preset dew point temperature difference threshold.

[0059] It should be noted that after determining the dew point temperature inside the vehicle in the embodiments provided by the present application, the dew point temperature difference between the dew point temperature and the in-vehicle temperature parameter is determined; if the dew point temperature difference is less than or equal to the preset dew point temperature difference threshold, it is determined that there is no need to turn on the in-vehicle air conditioner to defog the window, and the air outlet direction of the air conditioner is adjusted; when the dew point temperature difference is greater than the preset dew point temperature difference threshold, the in-vehicle air conditioner is turned on to defog the window.

[0060] The embodiments provided by the present application can further calculate the dew point temperature difference between the dew point temperature and the in-vehicle temperature parameter, and then compare the dew point temperature difference with the preset dew point temperature difference threshold. When the dew point temperature difference is less than or equal to the preset dew point temperature difference threshold, it is determined that the in-vehicle temperature will not cause water mist to condense on the window, so there is no need to turn on the in-vehicle air conditioner to defog the window, but the air outlet direction of the air conditioner needs to be adjusted; when the dew point temperature difference is greater than the preset dew point temperature difference threshold, the in-vehicle air conditioner is turned on to defog the window.

[0061] It can be understood that when the embodiments provided by the present application determine that the dew point temperature difference is less than or equal to the preset dew point temperature difference threshold, although there is no need to turn on the air volume of the air conditioner to defog the window, however, since there is indeed a difference between the in-vehicle and the preset dew point temperature difference, resulting in the in-vehicle personnel being able to feel the temperature difference change. To avoid the in-vehicle temperature affecting the physical sensation of the in-vehicle personnel (such as the driver), the air outlet direction of the air conditioner can be changed, and the minimum air volume can be used to directly blow on the in-vehicle personnel to ensure the physical sensation of the driver.

[0062] The preset dew point temperature difference threshold in the embodiments provided by the present application can be customarily set according to different application scenarios.

[0063] In some embodiments, the preset dew point temperature difference threshold in the embodiments provided by the present application can be set to: 2°C. When the dew point temperature difference ≤ 2°C, it is necessary to adjust the air outlet direction of the air conditioner so that the air outlet of the air conditioner faces the head of the driver (or other priority personnel in the vehicle) (since the skin of the head is usually exposed to the air, the body sensation temperature of the head is more easily perceived), and blow directly at the head of the vehicle occupants with the minimum air volume to ensure the body sensation of the driver.

[0064] S103. If necessary, based on the external vehicle environment parameters and the internal vehicle temperature parameters of the vehicle in the current environment, dynamically adjust the defogging level of the air conditioner for defogging the vehicle window, and defog the vehicle window according to the defogging level, where the external vehicle environment parameters include the external vehicle temperature parameter, the external vehicle humidity parameter, and the rain intensity parameter.

[0065] It should be noted that after the embodiments provided by the present application determine that it is necessary to turn on the air conditioner in the vehicle to defog the vehicle window, the embodiments provided by the present application can collect the external vehicle environment parameters of the vehicle in the current environment in real time through different types of external vehicle sensors, and after the collection, also filter the internal vehicle environment parameters collected by the above-mentioned external vehicle sensors to remove the noise in the data.

[0066] Through the above external vehicle environment parameters and the internal vehicle temperature parameters, dynamically adjust the defogging level of the air conditioner for defogging the vehicle window, and based on the corresponding defogging level and usage scenario, turn on the air conditioner to remove the water mist on the vehicle window inside the vehicle with different air volumes, different air outlet angles, and different cold and hot air mixing ratios, thereby realizing non-visible defogging inside the vehicle.

[0067] Here, when the battery of the vehicle in the embodiments provided by the present application is in the low power mode, the above-mentioned air conditioner will be controlled to dynamically switch the defogging mode for the vehicle window. For example, in the low power mode, the air conditioner will switch to the intermittent defogging mode.

[0068] It can be understood that the external vehicle temperature parameter in the embodiments provided by the present application can be collected using an internal and external vehicle temperature sensor, and the external vehicle temperature sensor in the embodiments provided by the present application can be a high-precision thermocouple or an infrared sensor for real-time monitoring of temperature changes.

[0069] In some embodiments, the accuracy of the external vehicle temperature sensor in the embodiments provided by the present application can be 0.5°C.

[0070] The external vehicle humidity parameter in the embodiments provided by the present application can be collected using an external vehicle humidity sensor, and the external vehicle humidity sensor in the embodiments provided by the present application can be a capacitive or resistive humidity sensor. In some embodiments, the accuracy of the external vehicle humidity sensor is 2% RH.

[0071] The rain intensity parameter in the embodiments provided by this application can be collected using a rain sensor. The rain sensor in the embodiments provided by this application can be a hardware device carried by the vehicle itself, which is used to detect the humidity change in rainy days and assist in judging the defogging requirement, thereby reducing the consumable cost.

[0072] Among them, the outside temperature sensor for collecting the outside temperature parameter and the outside humidity sensor for collecting the outside humidity parameter in the embodiments provided by this application can be, but are not limited to, integrally installed on the rearview mirror base or the front bumper.

[0073] Exemplarily, determining the dew point temperature inside the vehicle based on the in-vehicle environment parameters of the vehicle in the current environment includes: determining the initial dew point temperature inside the vehicle based on the in-vehicle temperature parameter and the in-vehicle humidity parameter of the vehicle in the current environment; correcting the initial dew point temperature based on the in-vehicle solar radiation intensity parameter of the vehicle in the current environment to determine the corrected dew point temperature inside the vehicle.

[0074] It should be noted that the dew point temperature in the embodiments provided by this application is jointly determined according to the in-vehicle temperature parameter, the in-vehicle humidity parameter, and the solar radiation intensity parameter, and the solar radiation intensity parameter is related to the heat conduction coefficient of the window glass.

[0075] Here, the formula for the dew point temperature inside the vehicle in the embodiments provided by this application is specifically:

[0076] Td = (H / 100)^(1 / 8) × (112 + 0.9T) + 0.1T - 112;

[0077] Among them, Td is used to represent the dew point temperature inside the vehicle; H is used to represent the in-vehicle humidity parameter; T is used to represent the in-vehicle temperature parameter; the heat conduction coefficient of the window glass is 1 / 8.

[0078] Exemplarily, please refer to Figure 2 , Figure 2 is a flowchart for determining the defogging level in a method for determining window defogging provided by an embodiment of this application. As Figure 2 shown, step S103 includes the following sub-steps:

[0079] S1031. Determine the temperature difference between the outside temperature parameter and the inside temperature parameter of the vehicle in the current environment.

[0080] It should be noted that the embodiments provided by this application will first determine the actual temperature difference between the outside temperature parameter and the inside temperature parameter in the current environment, and determine the opening method of the in-vehicle air conditioner, as well as the wind direction and air volume after opening, according to the magnitude of the above actual temperature difference.

[0081] S1032. If the temperature difference is within the preset temperature difference range, determine that the defogging level of the air conditioner for the vehicle window is the first-level defogging, where the first-level defogging is used to represent that the air conditioner uses the air volume within the target air volume range to defog the vehicle window.

[0082] It should be noted that when the actual temperature difference between the external temperature parameter and the internal temperature parameter in the front environment is determined to be within the preset temperature difference range in the embodiment provided by the present application, the vehicle window starts to be defogged according to the air volume within the preset target air volume range.

[0083] Among them, the preset temperature difference range in the embodiment provided by the present application can be specifically but not limited to 0.5°C - 1°C.

[0084] In some embodiments, the air volume within the target air volume range in the embodiment provided by the present application is specifically 40% - 60%.

[0085] S1033. Based on the rain intensity parameter, determine whether to control the air conditioner to turn on the external air circulation for the vehicle interior.

[0086] It should be noted that after the defogging starts in the embodiment provided by the present application, the rain intensity parameter collected by the rain sensor is used to determine whether it is raining in the external environment. If it is determined that it is raining in the external environment, in order to prevent rain from entering, the external air circulation of the air conditioner is not turned on; if it is determined that it is not raining in the external environment, the air conditioner in the vehicle can be turned on for external air circulation.

[0087] Exemplarily, the defogging level can also be determined in the following way:

[0088] If the temperature difference is less than or equal to the preset temperature difference, determine that the defogging level of the air conditioner for the vehicle window is the second-level defogging, determine that the defogging level of the air conditioner for the vehicle window is the second-level defogging, and control the seat in the vehicle to start seat heating, where the second-level defogging is used to represent that the air conditioner turns on full power to defog the vehicle window.

[0089] It should be noted that if the temperature difference is less than or equal to the preset temperature difference, it means that the temperature difference between the inside and outside of the vehicle is relatively large, and full-power defogging of the air conditioner is required, and the seat heating linkage function of the driver's seat and the passenger seat is turned on at the same time.

[0090] It can be understood that the preset temperature difference in the embodiment provided by the present application needs to be set according to different usage scenarios. The preset temperature difference in the present application can be the critical value 0.5°C at the lower end of the preset temperature difference range, or a preset value 0°C far lower than the preset temperature difference range.

[0091] Exemplarily, please refer to Figure 3 , Figure 3 is the flowchart of eliminating the rain intensity parameter in a method for determining window defogging provided by an embodiment of the present application. As Figure 3As shown below, the rain intensity parameter is eliminated in the following manner:

[0092] S301. If the outside humidity parameter of the vehicle is within the preset humidity range of the vehicle in the current environment, it is determined that the current environment is a non-rainy weather.

[0093] It should be noted that in the embodiments provided in the present application, the outside humidity sensor can be used to cross-verify the rain sensor. When the outside humidity parameter collected by the outside humidity sensor is within the preset humidity range, it is determined that the current environment detected by the outside humidity sensor is a non-rainy weather.

[0094] It can be understood that in the embodiments provided in the present application, the current environment of the vehicle is specifically set as: a sunny day at 35 degrees in summer, and the theoretically corresponding preset humidity range is 30% to 40% humidity.

[0095] S302. If it is determined that the current environment is a rainy weather based on the rain intensity parameter, it is determined that the rain intensity parameter is incorrect, the rain intensity parameter is eliminated, and the window is defogged based on the outside environment parameter and the inside temperature parameter after deleting the rain intensity parameter.

[0096] It should be noted that in the embodiments provided in the present application, if the rain sensor determines that the current environment is a rainy weather based on the collected rain intensity parameter, it indicates that the detection result of the outside humidity sensor is inconsistent with the detection result of the rain sensor. Furthermore, it is determined that the monitoring result of the rain sensor is incorrect, that is, the rain intensity parameter is incorrect. The rain intensity parameter needs to be eliminated, and the window is defogged again based on the outside environment parameter and the inside temperature parameter after deleting the rain intensity parameter, and the defogging level is determined.

[0097] Among them, eliminating the rain intensity parameter can exclude the situation of false triggering caused by the sudden change of the outside humidity on a rainy day. The specific situation may be: after the rain stops on the vehicle, there are still raindrops on the window of the vehicle. At this time, the rain sensor will still recognize the weather outside the vehicle as a rainy day. Then, the current detection result of the rain sensor does not match the actual current environment, and the rain intensity parameter detected by the rain sensor needs to be eliminated.

[0098] It can be understood that in the embodiments provided in the present application, when the outside humidity parameter detected by the outside humidity sensor is 35%, it is determined that the current outside humidity parameter is reasonable. If the outside humidity parameter detected by the rain sensor is 40% at this time, it is determined that the rain sensor is faulty, and further it is determined that the rain intensity parameter detected by the rain sensor is incorrect.

[0099] The method for determining window defogging provided by the embodiments of the present application, compared with the prior art, determines the dew point temperature inside the vehicle based on the in-vehicle environment parameters of the vehicle in the current environment, and determines whether to turn on the in-vehicle air conditioner to defog the window based on the dew point temperature, the in-vehicle temperature parameters, and a preset dew point temperature difference threshold. When it is necessary to turn on the in-vehicle air conditioner to defog the window, the defogging level of the air conditioner for defogging the window is dynamically adjusted based on the out-vehicle environment parameters and the in-vehicle temperature parameters of the vehicle in the current environment, realizing the dynamic coupling of the in-vehicle air conditioner parameters. The present application uses multi-dimensional environment parameters to identify and predict whether the window will fog up, reducing the interference of the external environment on the recognition result and improving the accuracy of recognition. Moreover, by setting the defogging level and dynamically adjusting the defogging effect of different levels, the present application reduces the energy consumption of the in-vehicle air conditioner while improving the accuracy of defogging prediction.

[0100] Figure 4 It is a flowchart of another method for determining window defogging provided by the embodiments of the present application. As Figure 4 shown, the method for determining window defogging includes:

[0101] S401. Determine the dew point temperature inside the vehicle based on the in-vehicle environment parameters of the vehicle in the current environment, where the in-vehicle environment parameters include in-vehicle temperature parameters, in-vehicle humidity parameters, and in-vehicle sunlight intensity parameters.

[0102] S402. Determine whether to turn on the in-vehicle air conditioner to defog the window based on the dew point temperature, the in-vehicle temperature parameters, and a preset dew point temperature difference threshold.

[0103] S403. If necessary, dynamically adjust the defogging level of the air conditioner for defogging the window based on the out-vehicle environment parameters and the in-vehicle temperature parameters of the vehicle in the current environment, and defog the window according to the defogging level, where the out-vehicle environment parameters include out-vehicle temperature parameters, out-vehicle humidity parameters, and rain intensity parameters.

[0104] S404. Obtain the light transmittance of the window after defogging.

[0105] S405. Determine whether to stop defogging the window based on the light transmittance and a preset light transmittance threshold.

[0106] It should be noted that if the embodiments of the present application detect that the light transmittance of the window after defogging reaches the preset light transmittance threshold, stop defogging the window; if it is detected that the light transmittance of the window after defogging still does not reach the preset light transmittance threshold, continue to defog the window to verify the closed-loop effect of defogging.

[0107] The method for determining window defogging provided by the embodiments of the present application, compared with the prior art, determines the dew point temperature inside the vehicle based on the in-vehicle environmental parameters of the vehicle in the current environment, and determines whether to turn on the air conditioner inside the vehicle to defog the window based on the dew point temperature, the in-vehicle temperature parameters, and a preset dew point temperature difference threshold. When it is necessary to turn on the air conditioner inside the vehicle to defog the window, the defogging level of the air conditioner for defogging the window is dynamically adjusted based on the out-vehicle environmental parameters and the in-vehicle temperature parameters of the vehicle in the current environment, realizing the dynamic coupling of the in-vehicle air conditioner parameters. The present application identifies and predicts whether the window will fog up through multi-dimensional environmental parameters, reduces the interference of the external environment on the recognition result, improves the accuracy of recognition, and by setting the defogging level and dynamically adjusting the defogging effect of different levels, reduces the energy consumption of the in-vehicle air conditioner while improving the accuracy of defogging prediction.

[0108] Figure 5 It is a flowchart of a device for determining window defogging provided by an embodiment of the present application. As Figure 5 shown, the device 500 for determining window defogging includes:

[0109] The first determination module 510 is configured to determine the dew point temperature inside the vehicle based on the in-vehicle environmental parameters of the vehicle in the current environment, where the in-vehicle environmental parameters include in-vehicle temperature parameters, in-vehicle humidity parameters, and in-vehicle sunlight intensity parameters.

[0110] The second determination module 520 is configured to determine whether to turn on the air conditioner inside the vehicle to defog the window based on the dew point temperature, the in-vehicle temperature parameters, and a preset dew point temperature difference threshold.

[0111] The adjustment module 530 is configured to, if necessary, dynamically adjust the defogging level of the air conditioner for defogging the window based on the out-vehicle environmental parameters and the in-vehicle temperature parameters of the vehicle in the current environment, and defog the window according to the defogging level, where the out-vehicle environmental parameters include out-vehicle temperature parameters, out-vehicle humidity parameters, and rain intensity parameters.

[0112] The acquisition module 540 is configured to acquire the light transmittance of the window after defogging.

[0113] The third determination module 550 is configured to determine whether to stop defogging the window based on the light transmittance and a preset light transmittance threshold.

[0114] Exemplarily, the first determination module 510 is specifically configured to:

[0115] Determine the initial dew point temperature inside the vehicle based on the in-vehicle temperature parameters and the in-vehicle humidity parameters of the vehicle in the current environment.

[0116] Based on the sunlight intensity parameter inside the vehicle under the current environment, the initial dew point temperature is corrected to determine the corrected dew point temperature inside the vehicle.

[0117] Exemplarily, the second determining module 520 is specifically configured to:

[0118] Determine the dew point temperature difference between the dew point temperature and the interior temperature parameter.

[0119] If the dew point temperature difference is less than or equal to a preset dew point temperature difference threshold, it is determined that there is no need to turn on the air conditioner in the vehicle to defog the windows, and the direction of the air outlet of the air conditioner is adjusted.

[0120] If the dew point temperature difference is greater than a preset dew point temperature difference threshold, it is determined that the air conditioner in the vehicle needs to be turned on to defog the windows.

[0121] Exemplarily, the adjustment module 530 is specifically configured to:

[0122] The temperature difference between the outside temperature parameter and the inside temperature parameter of the vehicle under the current environment is determined.

[0123] If the temperature difference is within a preset temperature difference range, the defog level of the air conditioner for defogging the vehicle windows is determined to be level one defog, wherein level one defog is used to indicate that the air conditioner defogs the vehicle windows using an air volume within a target air volume range.

[0124] Based on the rain intensity parameter, determine whether to control the air conditioner to start external circulation of air in the car.

[0125] Exemplarily, if the temperature difference is less than or equal to the preset temperature difference, the defog level of the air conditioner for defogging the vehicle windows is determined to be level two, and the seats in the vehicle are controlled to start seat heating, wherein level two defog is used to indicate that the air conditioner is turned on at full power to defog the vehicle windows.

[0126] Exemplarily, if the humidity parameter outside the vehicle is within a preset humidity range of the vehicle in the current environment, it is determined that the current environment is non-rainy weather.

[0127] If the current environment is determined to be rainy weather based on the rain intensity parameter, it is determined that the rain intensity parameter is wrong, the rain intensity parameter is eliminated, and the defog level of the air conditioner for defogging the windows is dynamically adjusted based on the external environment parameters and the internal temperature parameters, and the windows are defogged according to the defog level.

[0128] The window defogging determination device 500 provided by the embodiments of the present application, compared with the prior art, determines the dew point temperature inside the vehicle based on the in-vehicle environment parameters of the vehicle in the current environment, and determines whether to turn on the in-vehicle air conditioner to defog the window based on the dew point temperature, the in-vehicle temperature parameters, and a preset dew point temperature difference threshold. When it is necessary to turn on the in-vehicle air conditioner to defog the window, the defogging level of the air conditioner for defogging the window is dynamically adjusted based on the out-vehicle environment parameters and the in-vehicle temperature parameters of the vehicle in the current environment, realizing the dynamic coupling of the in-vehicle air conditioner parameters. The present application uses multi-dimensional environment parameters to identify and predict whether the window will fog up, reducing the interference of the external environment on the recognition result and improving the accuracy of recognition. Moreover, by setting the defogging level and dynamically adjusting the defogging effect of different levels, the present application reduces the energy consumption of the in-vehicle air conditioner while improving the accuracy of defogging prediction.
