[0052] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0053] This application provides a defogging method, see Figure 1 The demisting method provided in the embodiment of the present application includes steps 100 to 300, which are described in detail below.

[0054] Step 100, obtaining various environmental data of the vehicle.

[0055] Among them, environmental data refers to data that characterizes the environment in which the vehicle is located, and its type can be set according to actual conditions. For example, the environmental data may include real data of the vehicle's environment and theoretical data of the vehicle's environment. The real data may include, for example, temperature values, humidity values, illuminance values, and light intensity values. The theoretical data may include, for example, meteorological data of the vehicle's environment. This embodiment is not limited here.

[0056] In some embodiments, the vehicle may acquire multiple environmental data through sensors and / or data interfaces. When the environmental data includes real data and theoretical data, the vehicle may collect real data through sensors and acquire theoretical data through data interfaces.

[0057] In some embodiments, the multiple environmental data include first environmental data and second environmental data, and obtaining the multiple environmental data of the vehicle includes:

[0058] The first environment data of the vehicle is collected through a sensor associated with the vehicle, and the second environment data of the vehicle is acquired through a data interface.

[0059] The sensor associated with the vehicle refers to a sensor on the vehicle. The first environment data refers to real data of the environment in which the vehicle is located, and the second environment data refers to theoretical data of the environment in which the vehicle is located. The first environment data may include at least one, and the second environment data may include at least one.

[0060] In this embodiment, the multiple environmental data include first environmental data and second environmental data. The first environmental data of the vehicle is collected by a sensor associated with the vehicle, and the second environmental data of the vehicle is acquired through a data interface, so as to determine the defog mode based on the first environmental data and the second environmental data. The defog mode is determined based on the diversified environmental data, thereby improving the accuracy of the defog mode and further improving the defog effect.

[0061] In some embodiments, when environmental data is collected by sensors, the position of the sensor on the vehicle can be set according to actual conditions. For example, when the environmental data includes temperature values, humidity values, illuminance values, and light intensity values, the sensor can include a temperature and humidity sensor and a photosensor. The temperature and humidity values ​​are collected by the temperature and humidity sensor, and the illuminance values ​​and light intensity values ​​are collected by the photosensor. The positions of the temperature and humidity sensor and the photosensor on the vehicle can be as follows: Figure 2 As shown, Figure 2 11 indicates a temperature and humidity sensor, which is installed on the internal circulation vent of the vehicle. Figure 2 Reference numerals 13 and 14 denote light-sensitive sensors, which are mounted on the front windshield of the vehicle.

[0062] In some embodiments, the vehicle may periodically acquire various environmental data of the vehicle.

[0063] Step 200, determining a defog mode of the vehicle according to a variety of environmental data.

[0064] Among them, the defog mode refers to the defog method. When the environmental data is different, the defog mode is different, and the defog operation corresponding to different defog modes is different. According to a variety of environmental data, the defog mode of the vehicle is determined, so that the defog mode can be matched with the environment in which the vehicle is located, so that the defog operation matching the environment in which the vehicle is located can be performed, so that not only automatic defog can be achieved, the defog efficiency can be improved, and energy consumption can be reduced, but also the defog effect can be improved.

[0065] Optionally, the terminal may determine a defog mode for the vehicle from preset defog modes based on a variety of environmental data.

[0066] The type of defog mode can be set according to actual conditions. For example, the defog mode includes one of the heating defog mode, the ventilation defog mode, the nano-coating defog mode and the ultrasonic vibration defog mode. At this time, the preset defog mode includes at least two of the heating defog mode, the ventilation defog mode, the nano-coating defog mode and the ultrasonic vibration defog mode, which is not limited in this embodiment.

[0067] In some embodiments, the method of determining the defog mode of the vehicle based on various environmental data can be set according to actual conditions, which is not limited in this embodiment.

[0068] For example, the vehicle's defog mode is determined based on a variety of environmental data, including:

[0069] A variety of environmental data are mapped and processed to obtain the vehicle's defog mode.

[0070] For example, the vehicle's defog mode is determined based on a variety of environmental data, including:

[0071] Selecting a plurality of data combinations from the plurality of environmental data, each data combination including at least two environmental data;

[0072] Determining a candidate defog mode for the vehicle based on each data combination respectively;

[0073] Based on the candidate defog modes, a defog mode for the vehicle is determined.

[0074] Among them, multiple data combinations can be selected from multiple environmental data according to the preset data combination type. For example, the preset data combination type includes data combination type c1, data combination type c2 and data combination type c3, data combination type c1 includes temperature type and humidity type, data combination type c2 includes illuminance type and meteorological type, data combination type includes temperature type, humidity type and meteorological type, according to data combination type c1, data combination 1 can be obtained, data combination 1 includes temperature value and humidity value, according to data combination type c2, data combination 2 can be obtained, data combination 2 includes illuminance value and meteorological data, according to data combination type c3, data combination 3 can be obtained, data combination 3 includes temperature value, humidity value and meteorological data. This embodiment is not limited here.

[0075] After obtaining each data combination, the terminal can determine a candidate defog mode based on each data combination, and finally determine the defog mode of the vehicle based on each candidate defog mode.

[0076] For example, the data combination includes data combination 1, data combination 2 and data combination 3. The candidate defog mode a1 is determined according to data combination 1, the candidate defog mode a2 is determined according to data combination 2, and the candidate defog mode a3 is determined according to data combination 3. The defog mode of the vehicle is determined according to the candidate defog mode a1, the candidate defog mode a2 and the candidate defog mode a3.

[0077] In this embodiment, multiple data combinations are selected from a variety of environmental data, each data combination includes at least two kinds of environmental data, and candidate defog modes for the vehicle are determined based on each data combination, and the defog mode of the vehicle is determined based on the candidate defog modes, thereby ensuring the diversity of the candidate defog modes obtained through data combinations, and further improving the accuracy of the defog mode determined based on the candidate defog modes.

[0078] In some embodiments, the method of determining the candidate defog mode of the vehicle based on the data combination can be set according to actual conditions. For example, the environmental data in the data combination can be mapped and processed through a preset function to obtain the candidate defog mode of the vehicle. Alternatively, the candidate defog mode of the vehicle can be determined based on the data combination through a neural network model. The embodiments of the present application are not limited here.

[0079] The type of the neural network model can be set according to actual conditions. For example, the neural network model can be a decision tree or a support vector machine, which is not limited in the embodiments of the present application.

[0080] In some embodiments, when determining a candidate defog mode for a vehicle based on a data combination through a decision tree, a plurality of data combinations are selected from a plurality of environmental data, including:

[0081] Select the data combination corresponding to each decision tree from a variety of environmental data;

[0082] Based on each data combination, a candidate defog mode for the vehicle is determined, including:

[0083] Through each decision tree, based on the data combination corresponding to each decision tree, the candidate defog mode of the vehicle is determined.

[0084] Among them, a sample data combination can be determined in advance from a variety of sample environment data, and the sample data combination includes at least two types of sample environment data. The initial decision trees are trained respectively through the sample data combinations of the same type to obtain the decision trees.

[0085] For example, the sample environmental data includes sample temperature values, sample humidity values, sample illuminance values, sample light intensity values ​​and sample meteorological data. According to the sample temperature values ​​and the sample humidity values, multiple sample data combinations are generated. According to the sample temperature values, the sample humidity values ​​and the sample meteorological data, multiple sample data combinations are generated. According to the illuminance values, the light intensity values ​​and the sample meteorological data, multiple sample data combinations generated according to the sample temperature values ​​and the sample humidity values ​​belong to the same type of sample data combinations. According to the sample temperature values, the sample humidity values ​​and the sample meteorological data, multiple sample data combinations generated according to the sample illuminance values, the sample light intensity values ​​and the sample meteorological data belong to the same type of sample data combinations.

[0086] It can be understood that when determining a sample data combination from a plurality of sample environment data, the sample environment data to be combined can be randomly selected from the plurality of sample environment data, and then the sample environment data to be combined can be formed into a sample data combination.

[0087] After the decision tree is trained, the decision tree has a corresponding type. After obtaining a variety of environmental data, the data combination corresponding to the decision number can be determined from the various environmental data according to the type corresponding to the decision tree.

[0088] For example, the initial decision tree is trained according to multiple sample data combinations generated by sample temperature values ​​and sample humidity values ​​to obtain decision tree d1. The types corresponding to decision tree d1 are temperature type and humidity type, and the data combination corresponding to decision tree d1 includes temperature value and humidity value. The initial decision tree is trained according to multiple sample data combinations generated by sample temperature value, sample humidity value and sample meteorological data to obtain decision tree d2. The types corresponding to decision tree d2 are temperature type, humidity type and meteorological type, and the data combination corresponding to decision tree d2 includes temperature value, humidity value and meteorological data. The initial decision tree is trained according to multiple sample data combinations generated by sample illuminance value, sample light intensity value and sample meteorological data to obtain decision tree d3. The types corresponding to decision tree d3 are illuminance type, light intensity type and meteorological type, and the data combination corresponding to decision tree d3 includes illuminance value, light intensity value and meteorological data.

[0089] After obtaining the data combination corresponding to the decision tree, the vehicle inputs the environmental data in the data combination corresponding to the decision tree into the decision tree for decision processing to obtain a candidate defog mode.

[0090] For example, the decision tree includes decision tree d1, decision tree d2 and decision tree d3. The data combination corresponding to decision tree d1 is data combination 1, the data combination corresponding to decision tree d2 is data combination 2, and the data combination corresponding to decision tree d3 is data combination 3. The environmental data in data combination 1 is input into decision tree d1 for decision processing to obtain a candidate defog mode. The environmental data in data combination 2 is input into decision tree d2 for decision processing to obtain a candidate defog mode. The environmental data in data combination 3 is input into decision tree d3 for decision processing to obtain a candidate defog mode.

[0091] In this embodiment, a data combination corresponding to each decision tree is selected from a variety of environmental data, and a candidate defog mode for the vehicle is determined through each decision tree based on the data combination corresponding to each decision tree, thereby achieving determination of the candidate defog mode through the decision tree and improving the accuracy of determining the candidate defog mode.

[0092] In some embodiments, determining a defogging mode for a vehicle based on candidate defogging modes includes:

[0093] Voting is performed on each candidate defogging mode to obtain a voting result;

[0094] Based on the voting results, the defog mode of the vehicle is determined.

[0095] Among them, the voting method for each candidate defog mode can be set according to the actual situation. For example, each candidate defog mode can be voted by soft voting or hard voting, which is not limited in this embodiment.

[0096] It is understandable that when voting on each candidate defogger mode, if the final voting result can obtain at least two defogger modes, then according to the priorities corresponding to the at least two defogger modes, the defogger mode with the highest priority is determined as the defogger mode of the vehicle.

[0097] In some embodiments, determining a defogging mode for a vehicle based on candidate defogging modes includes:

[0098] Get the weight corresponding to each data combination;

[0099] Based on the weight corresponding to each data combination and the candidate defog mode, the defog mode of the vehicle is determined.

[0100] Among them, the weight corresponding to each data combination can be a pre-set coefficient. When the vehicle obtains the candidate defog mode, it can use the probability coefficient corresponding to the candidate defog mode. The vehicle multiplies the weight corresponding to each data combination and the probability coefficient of the candidate defog mode determined based on each data combination to obtain the target probability coefficient corresponding to each candidate defog mode. Finally, based on the target probability coefficient corresponding to each candidate defog mode, the vehicle's defog mode is determined.

[0101] In this embodiment, the weight corresponding to each data combination is obtained, and the defog mode of the vehicle is determined based on the weight corresponding to each data combination and the candidate defog mode, thereby improving the accuracy of the determined defog mode.

[0102] It can be understood that when the candidate defog modes are determined through a decision tree, the weight corresponding to each data combination can also be referred to as the weight corresponding to each decision tree.

[0103] In some embodiments, the defogging mode of the vehicle is determined based on a variety of environmental data, including:

[0104] Get the vehicle's energy data;

[0105] The vehicle's defog mode is determined based on a variety of environmental data and energy data.

[0106] Among them, the vehicle's energy data refers to information related to the energy used by the vehicle, which can be set according to actual conditions. For example, the energy data can be an energy consumption rate or a remaining amount of energy, which is not limited in this embodiment.

[0107] In this embodiment, the energy data of the vehicle is obtained, and the defog mode of the vehicle is determined based on a variety of environmental data and energy data, thereby further improving the accuracy of the defog mode.

[0108] In some embodiments, the defogging mode of the vehicle is determined based on a variety of environmental data, including:

[0109] Get the defog level;

[0110] Determine the vehicle's defog mode based on the defog level and various environmental data.

[0111] Among them, the higher the defog level, the greater the defog intensity and / or the faster the speed, the better the defog effect, and the lower the defog level, the smaller the defog intensity and / or the slower the speed, the worse the defog effect.

[0112] For example, environmental data include temperature values, humidity values, illuminance values, light intensity values ​​and meteorological data. When the temperature value of the vehicle's glass surface is 5°C lower than the outside temperature, when the humidity value inside the vehicle exceeds 70%RH and the defog level is at the normal level, the vehicle's defog mode is determined to be heating defog; when the temperature difference between inside and outside the vehicle is less than 5°C, the humidity value inside the vehicle is between 60% and 70%RH, the external humidity value is low and the defog level is at the normal level, ventilation defogger is started; when the meteorological data is heavy rain and snow, the glass transparency (glass transparency is determined according to illuminance and light intensity) is lower than 80%, the defog level is at the highest level and the remaining energy is lower than 25%, the vehicle's defog mode is determined to be nano-coating defog; when the meteorological data is heavy rain and snow, the glass transparency is lower than 50% and the defog level is at the highest level, the vehicle's defog mode is determined to be ultrasonic vibration defogger.

[0113] In this embodiment, the demisting level is obtained, and the demisting mode of the vehicle is determined according to the demisting level and various environmental data, so that the determined demisting mode is more accurate.

[0114] In some embodiments, the defog level may be a defog level manually set by a user, or the defog level may be a defog level automatically determined by the vehicle. When the defog level is a defog level automatically determined by the vehicle, the environmental data includes light parameters of light incident on the glass of the vehicle, and obtaining the defog level includes:

[0115] Based on the light parameters, determine the transparency of the glass;

[0116] Based on the transparency, the defogging level is determined.

[0117] The light parameters may include a light intensity value and a light illuminance value. The higher the transparency, the lower the defog level, and the lower the transparency, the higher the defog level.

[0118] Optionally, the defogging level may be determined according to transparency and meteorological data. For example, when the transparency of the glass is lower than 30% and the weather condition is severe, the defogging level is the highest level.

[0119] In this embodiment, the transparency of the glass is determined based on the light parameters, and the defog level is determined based on the transparency, so that the defog level can be automatically determined and the accuracy of the defog level can be improved.

[0120] In some embodiments, when determining the candidate defog mode based on the data combination and determining the defog mode based on the candidate defog mode, the candidate defog mode can be determined based on the data combination and the defog level and the defog mode can be determined based on the candidate defog mode.

[0121] Step 300, controlling the vehicle to perform a defog operation corresponding to the defog mode.

[0122] Different defogger modes correspond to different defogger operations. For example, when the defogger mode is the heating defogger mode, the defogger operation can be heating by electric heating wire or thin film heating technology to quickly increase the temperature of the vehicle's glass surface and eliminate temperature difference fog. The heating time and power of the electric heating wire are controlled to ensure that the temperature of the glass surface is evenly increased to avoid local overheating. The transparent conductive film is used as a heating element and heated by the heating element to achieve the purpose of rapid defoggering without affecting the driver's vision.

[0123] When the defog mode is the ventilation defog mode, the defog operation can be to adjust the size and position of the vents through a motor to automatically adjust the air circulation inside and outside the vehicle, and use the airflow to remove the fog attached to the glass.

[0124] When the defog mode is the nano-coating defog mode, the defog operation is to apply a nano-hydrophobic coating on the glass surface to reduce moisture condensation and fundamentally inhibit fog generation. At this time, the coating performance can also be regularly tested through performance detection devices. The coating performance includes hydrophobicity, wear resistance and transparency, etc., to ensure the effectiveness of the coating.

[0125] When the defog mode is the ultrasonic vibration defog mode, the defog operation is to generate high-frequency ultrasonic vibrations, which break the combination of water molecules on the glass surface to achieve rapid defog. At this time, the frequency and intensity of the ultrasonic vibrations can be intelligently controlled to achieve the best defog effect. It should be noted that the frequency threshold of ultrasonic vibrations is usually between 20kHz and 40kHz, which can be adjusted according to the viscosity of the fog.

[0126] In some embodiments, when the defog mode is determined through a decision tree, if the user adjusts the defog mode after the defog mode is determined, a variety of environmental data can be used as sample environmental data, and the decision tree can be fine-tuned based on the adjusted defog mode and the sample environmental data, so as to further improve the subsequent defog mode determined by the fine-tuned decision tree to better meet user needs.

[0127] In some embodiments, when the defog mode is determined based on weights and candidate defog modes, if the user adjusts the defog mode after determining the defog mode, the weight can be adjusted based on the adjusted defog mode to improve the subsequent defog mode determined based on the weight to better meet user needs.

[0128] In some embodiments, during the execution of a defog operation corresponding to a defog mode, new environmental data may be acquired. If a new defog mode determined based on the new environmental data is different from the defog mode corresponding to the defog operation being executed, the defog operation corresponding to the new defog mode is executed.

[0129] In some embodiments, controlling the vehicle to perform a defog operation corresponding to the defog mode includes:

[0130] Get the vehicle's power parameters;

[0131] Select the energy type corresponding to the power parameter;

[0132] By energy type, the vehicle is controlled to perform the defog operation corresponding to the defog mode.

[0133] Among them, the power parameter is used to indicate the power of the vehicle. If it indicates that the power of the vehicle is insufficient, the selected energy type is the heat energy type recovered by the heat energy recovery system, and the defog operation corresponding to the defog mode is performed through the recovered heat energy. If it indicates that the power of the vehicle is sufficient, the selected energy type is the battery type, and the defog operation corresponding to the defog mode is performed through the battery.

[0134] In this embodiment, the power parameters of the vehicle are obtained, and the energy type corresponding to the power parameters is selected. Through the energy type, the vehicle is controlled to perform the defog operation corresponding to the defog mode, thereby achieving flexible energy supply for the defog operation, ensuring the continuous and stable operation of the defog operation, and reducing energy consumption.

[0135] In an embodiment of the present application, various environmental data of the vehicle are obtained, and the defog mode of the vehicle is determined based on the various environmental data. The vehicle is controlled to perform the defog operation corresponding to the defog mode, thereby automatically removing the fog on the vehicle and improving the defog effect and safety.

[0136] In some embodiments, the present application provides a defog system, which includes a perception module, a defog control module and a multi-mode execution module. The perception module is used to obtain a variety of environmental data, the defog control module is used to determine the defog mode based on the various environmental data, and the multi-mode execution module is used to control the vehicle to perform the defog operation corresponding to the defog mode.

[0137] Optionally, the perception module includes a temperature and humidity sensor, a data interface and a photosensor. The temperature and humidity sensor is used to collect temperature and humidity values ​​inside and outside the vehicle, the data interface is used to obtain meteorological data, and the photosensor is used to obtain illuminance and light intensity values.

[0138] Optionally, the defog control module includes a microprocessing unit, an intelligent algorithm unit, a defog control unit and a defog level unit, wherein the microprocessing unit is used to determine the temperature difference according to the temperature values ​​inside and outside the vehicle, and to determine the glass transparency according to the illuminance value and the light intensity value, and the intelligent algorithm unit is used to determine the defog mode according to the temperature difference, the glass transparency and the meteorological data. The defog control unit is used to start and stop the defog operation. The defog level unit is used to determine the defog level.

[0139] Optionally, the multi-mode execution module includes a heating unit, a ventilation and demisting unit, a nano-coating unit and an ultrasonic vibration unit. In this case, the demisting system can be as follows: Figure 3As shown. The heating unit is used to control the heating time and power of the electric heating wire to ensure that the temperature of the glass surface is evenly increased to avoid local overheating. The transparent conductive film is used as a heating element and heated by the heating element to achieve the purpose of rapid defogging without affecting the driving line of sight. It is fast and effective and suitable for various windows. The ventilation and defogging unit is used to adjust the size and position of the vents through the motor to automatically adjust the air circulation inside and outside the car, and use the airflow to remove the fog attached to the glass, so that the fog can be removed while maintaining the air circulation in the car.
