[0002] With the development of the automotive industry, more and more cars are involved in our lives. When the vehicle is driving, if the external temperature of the vehicle is relatively low, due to the high temperature and humidity of the air exhaled by passengers, condensation is likely to occur inside the vehicle, affecting the experience of the driver and passengers. Therefore, how to achieve intelligent selection of the target defogging device for the vehicle to remove the fog on the inner side of the windshield in the vehicle is an urgent problem to be solved currently.

[0073] Figure 1 It is a schematic diagram of a vehicle defogging scenario provided by an embodiment of the present application.

[0074] Exemplarily, as Figure 1 shown, the vehicle 100 includes a windshield 110 and a plurality of vehicle windows; for example, the plurality of vehicle windows include: a vehicle window 120, a vehicle window 130, and a vehicle window 140; when the external temperature of the vehicle 100 is relatively low, due to the relatively high temperature and humidity of the air exhaled by passengers, condensation may occur on the inner side of the windshield 110 in the vehicle 100 (i.e., the side of the windshield 110 in contact with the cockpit), the vehicle window 120, the vehicle window 130, and the vehicle window 140, affecting the experience of the driver and passengers.

[0075] It should be understood that the vehicle 100 in Figure 1 may be a 5-seat vehicle, an 8-seat vehicle, etc. The embodiments of the present application do not impose any limitation on the number of seats in the vehicle 100.

[0076] To solve the above problems, the present application proposes a vehicle defogging method, which can determine the target defogging device in the vehicle according to the weather information of the driving environment where the vehicle is located; realize the intelligent selection of the target defogging device in the vehicle to remove the fog on the inner side of the windshield in the vehicle.

[0077] Figure 2 It is a schematic diagram of a system architecture of a vehicle provided by an embodiment of the present application.

[0078] Exemplarily, as Figure 2 shown, the vehicle 100 includes a sensor 150, a vehicle control system 160, and a target defogging device 170; wherein, the sensor 150 includes a temperature sensor 1501, a humidity sensor 1502, and a rain sensor 1503; the target defogging device 170 includes an air conditioner 1701 and a window 1702.

[0079] The sensor 150 is connected to the vehicle control system 160, and the sensor 150 is used to send information about the temperature inside the vehicle, the temperature outside the vehicle, and the humidity outside the vehicle to the vehicle control system 160.

[0080] The target defogging device 170 is connected to the vehicle control system 160, and the target defogging device 170 is used to receive an opening instruction of the target defogging device from the vehicle control system 160.

[0081] Next, taking the Figure 2 system architecture shown as an example, in combination with Figure 3 and Figure 4 the vehicle defogging method provided by an embodiment of the present application will be described in detail.

[0082] Figure 3 It is a schematic flowchart of a vehicle defogging method provided by an embodiment of the present application.

[0083] Exemplarily, Figure 3 the method 200 shown can be executed by the Figure 1 vehicle 100 shown; or, by the Figure 1 vehicle controller in the vehicle 100 shown; or, by the Figure 1 processor or chip in the vehicle 100 shown; or, it can be executed by the Figure 2 vehicle control system 160 shown.

[0084] S210, if it is detected that the vehicle has a defogging requirement, obtain the weather information of the driving environment where the vehicle is located.

[0085] Exemplarily, the defogging requirement means that when there is fog inside the vehicle, at this time the vehicle has a defogging requirement, wherein, the inside of the vehicle includes the window and the front and rear windshield of the vehicle. The weather information refers to the current weather condition, for example, the weather information is sunny, cloudy, rainy, and snowy. In the embodiments of the present application, the defogging method of the vehicle is specifically explained and illustrated by taking the windshield as an example.

[0086] For example, when the vehicle is in a driving state, if it is detected that the vehicle has a defogging requirement, obtain the weather information of the driving environment where the vehicle is located.

[0087] In one example, weather information of the driving environment where the vehicle is located can be obtained through the signal of a rain sensor in the vehicle.

[0088] Optionally, in the embodiments of the present application, for the vehicle to have a defogging need, it includes cases where the inner side of the front windshield of the vehicle has a defogging need, or the inner side of the rear windshield of the vehicle has a defogging need, or the inner side of the vehicle window has a defogging need, etc.

[0089] S220. Determine the target defogging device in the vehicle according to the weather information.

[0090] Exemplarily, the target defogging device includes the air conditioner and the vehicle window in the vehicle. For example, defogging can be performed by adjusting the air volume, wind speed or temperature of the air conditioner in the vehicle, or by controlling the opening of the vehicle window for defogging.

[0091] In one implementation manner, if it is detected that the vehicle has a defogging need, obtaining the weather information of the driving environment where the vehicle is located includes:

[0092] Obtain the signal collected by the rain sensor in the vehicle;

[0093] Determining the target defogging device in the vehicle according to the weather information includes:

[0094] If the signal indicates that the driving environment is a rainy environment or a snowy environment, determine that the target defogging device is the air conditioner in the vehicle;

[0095] If the signal indicates that the driving environment is a target environment, determine that the target defogging device is the vehicle window in the vehicle, and the target environment refers to the driving environment other than the rainy environment and the snowy environment.

[0096] Exemplarily, sensors in the vehicle (such as a rain sensor, a camera) can monitor the rainfall on the front windshield of the vehicle, obtain the signal collected by the rain sensor, and send the result to the body domain controller of the vehicle, and the body domain controller can transmit the monitored result to the Controller Area Network (CAN).

[0097] Exemplarily, the signal collected by the rain sensor can indicate whether the weather in the current driving environment is a rainy environment or a snowy environment; for example, when the signal collected by the rain sensor is at a high level, it is determined that the current vehicle is in a rainy environment or a snowy environment in the driving environment; when the signal collected by the rain sensor is at a low level, it is determined that the current vehicle is not in a rainy environment or a snowy environment in the driving environment.

[0098] In an embodiment of the present application, a signal collected by a rain sensor in a vehicle is obtained, and weather information of the driving environment where the vehicle is located is determined according to the obtained signal collected by the rain sensor; when the weather information indicates a rainy environment or a snowy environment, it is determined that the target defogging device in the vehicle is the air conditioner in the vehicle; when the weather information indicates a situation other than a rainy environment or a snowy environment, it is determined that the target defogging device in the vehicle is the window of the vehicle; since in a rainy environment or a snowy environment, it is easy for rain or snow to enter the driver's cab of the vehicle by opening the window for defogging, therefore, in a rainy environment or a snowy environment, it is determined that the target defogging device in the vehicle is the air conditioner; by controlling the air conditioner in the vehicle to turn on, the fog on the inner side of the windshield in the vehicle is removed; in addition, when the driving environment where the vehicle is located is an environment other than a rainy environment or a snowy environment, it is determined that the target defogging device in the vehicle is the window, and by controlling the window in the vehicle to open, the fog on the inner side of the windshield in the vehicle is removed on the premise of saving the power consumption of the vehicle; in this solution, according to the weather information of the driving environment where the vehicle is located, the target defogging device in the vehicle can be determined; the vehicle can intelligently select the target defogging device to remove the fog on the inner side of the windshield in the vehicle.

[0099] In one implementation, when the signal indicates that the driving environment is a target environment and it is determined that the target defogging device is the window of the vehicle, it includes:

[0100] If the signal indicates that the driving environment is a target environment, according to the distances between the respective windows in the vehicle and the windshield, the target defogging device is determined to be the target window in the vehicle, and the distance between the target window and the glass is less than a preset distance threshold.

[0101] Wherein, the preset distance threshold may be the maximum value of the distance between the vehicle and the windshield configured in advance; for example, the preset distance threshold is 50 cm.

[0102] Exemplarily, assuming that the preset distance threshold is 50 cm, taking a five-seater vehicle as an example, the distances between the four windows and the windshield are detected to be 40 cm, 40 cm, 1.5 m, and 1.5 m respectively. Therefore, the window corresponding to a distance of 40 cm from the windshield is determined as the target window. It can be understood that the target window refers to the window with a relatively short distance from the windshield; optionally, the target window can be one window or multiple windows, and the present application does not make any limitation thereto.

[0103] For example, as Figure 1 shown, when there is fog on the inner side of the windshield 110 in the vehicle 100, the target window may refer to the window 120 with a relatively short distance from the windshield.

[0104] For example, as Figure 1As shown, when fog appears on the inner side of the rear windshield in the vehicle 100, the target window can refer to the window 130 or the window 140 that is relatively close to the rear windshield.

[0105] In an embodiment of the present application, when it is determined that the target defogging device is a window in the vehicle, the distances between each window in the vehicle and the windshield are obtained to obtain a plurality of distances; the plurality of distances are compared with a preset distance threshold to determine the target window in the vehicle; by controlling the opening of the target window, the fog on the inner side of the windshield in the vehicle is removed; since the target window is the window in the vehicle whose distance from the windshield is less than the preset threshold, that is, the target window refers to the window that is relatively close to the windshield, by controlling the opening of the target window, the defogging efficiency can be improved.

[0106] In one implementation, when the target defogging device is the air conditioner in the vehicle, controlling the target defogging device to turn on to remove the fog on the inner side of the windshield in the vehicle includes:

[0107] Controlling the air conditioner in the vehicle to turn on and controlling the air direction mode of the air conditioner to be in the direction of the windshield, so as to remove the fog on the inner side of the windshield in the vehicle.

[0108] Exemplarily, the air direction mode of the air conditioner in the vehicle includes a mode of blowing towards the user's face, a mode of blowing towards the windshield, a mode of blowing towards the user's feet, etc.; in addition, the air outlet mode of the air conditioner can be controlled by means of a knob or a soft switch; if it is detected that the windshield has a defogging requirement, the air direction mode of the air conditioner in the vehicle can be controlled to be the mode of blowing towards the windshield.

[0109] In an embodiment of the present application, when it is determined that the target defogging device is the air conditioner, controlling the air direction mode of the air conditioner to be in the direction of the windshield; since the air direction mode of the air conditioner in the vehicle is controlled to be in the direction of the windshield, the speed of removing the fog on the windshield is increased, thereby improving the defogging efficiency of the vehicle.

[0110] In one implementation, when the target defogging device is the air conditioner in the vehicle, controlling the target defogging device to turn on to remove the fog on the inner side of the windshield in the vehicle includes:

[0111] According to the area of the fog on the inner side of the windshield, controlling the air volume and / or temperature of the air conditioner to remove the fog on the inner side of the windshield in the vehicle.

[0112] Exemplarily, the air volume output by the air conditioner refers to the magnitude of the air volume blown out by the air conditioner; for example, the air volume output by the air conditioner includes: the air volume at gear 1 (e.g., a small air volume), the air volume at gear 2 (e.g., a medium air volume), the air volume at gear 3 (e.g., a large air volume), etc.; the temperature of the air conditioner includes: the outlet temperature at gear 1 (e.g., a lower temperature), the temperature at gear 2 (e.g., a medium temperature), the temperature at gear 3 (e.g., a higher temperature), etc.; by separately controlling the air volume output or the temperature of the air conditioner, the air volume output and temperature of the air conditioner can also be arranged and combined to achieve the defogging effect; for example, controlling the air volume output of the air conditioner to be large and the temperature of the air conditioner to be low, etc.

[0113] In one example, the fog area on the inner side of the windshield is recognized by a camera in the vehicle cockpit; when it is detected that the fog area is greater than a preset area threshold, the air volume output of the air conditioner can be increased and the outlet temperature of the air conditioner can be decreased; when it is detected that the fog area is less than or equal to the preset area threshold, the air volume output of the air conditioner can be decreased and the outlet temperature of the air conditioner can be increased.

[0114] For example, the controller of the vehicle monitors the current fog area, thereby controlling the air volume output and / or temperature of the vehicle air conditioner, wherein the current fog area can be classified into levels, and different levels correspond to different combinations of air volume output and temperature; for example, when the current fog area is at level 1, the corresponding air volume output is small and the temperature is medium; when the current fog area is at level 2, the corresponding air volume output is medium and the temperature is medium; when the current fog area is at level 3, the corresponding air volume output is large and the temperature is high.

[0115] It should be noted that the corresponding relationship between the above fog area levels and the air volume output and temperature can be set by oneself, and the embodiments of the present application do not limit this.

[0116] In the embodiments of the present application, when it is determined that the target defogging device is the air conditioner, the air volume output and / or temperature of the air conditioner is controlled according to the fog area on the windshield. By controlling the air volume output and / or temperature of the air conditioner, the intelligence of the defogging method is improved.

[0117] In one implementation, the above vehicle defogging method further includes:

[0118] Detecting the number of users in the vehicle and the outside temperature of the vehicle;

[0119] If the number of users is greater than a preset threshold and the outside temperature is less than a preset temperature threshold, it is determined that the vehicle has a defogging requirement.

[0120] Exemplarily, by separately detecting and comparing the number of users in the vehicle with a preset threshold, and comparing the outside temperature of the vehicle with a preset temperature threshold, when the number of users is greater than the preset threshold and the outside temperature is less than the preset temperature threshold, it is determined that the vehicle has a defogging requirement; wherein, the number of users in the vehicle refers to the number of people taking the vehicle under the current condition; for example, the number of users is 3. The preset threshold refers to the maximum value of the number of people taking the vehicle configured in advance; for example, the preset threshold is 5. The preset temperature threshold refers to the threshold of the temperature configured in advance; for example, the preset temperature threshold is 10°C.

[0121] By comparing the number of users with the preset threshold and comparing the outside temperature of the vehicle with the preset temperature threshold, the following results may occur: the number of users is less than the preset threshold and the outside temperature is less than the preset temperature threshold; the number of users is less than the preset threshold and the outside temperature is greater than the preset temperature threshold; the number of users is greater than the preset threshold and the outside temperature is less than the preset temperature threshold; the number of users is greater than the preset threshold and the outside temperature is greater than the preset temperature threshold, and when it is detected that the number of users is greater than the preset threshold and the outside temperature is less than the preset temperature threshold, it is considered that the vehicle has a defogging requirement.

[0122] It should be noted that the above preset threshold and preset temperature threshold are for illustrative purposes, and the present application makes no limitations thereto.

[0123] In the embodiments of the present application, it is determined whether the vehicle has a defogging requirement according to the number of users in the cockpit of the vehicle and the outside temperature. When it is detected that the number of users is greater than the preset threshold and the outside temperature is less than the preset temperature threshold, it is determined that the vehicle has a defogging requirement; through the user data in the vehicle and the outside temperature, it is intelligently recognized whether the vehicle specifically has a defogging requirement, improving the intelligence level of the defogging function.

[0124] In one implementation, the defogging method further includes:

[0125] Real-time collect the outside temperature, inside temperature and inside humidity of the vehicle; obtain a condensation value according to the outside temperature, outside temperature and inside humidity;

[0126] If the condensation value is greater than or equal to a preset condensation threshold, it is determined that the vehicle has a defogging requirement.

[0127] Among them, the temperature sensors of the vehicle acquire the in-vehicle temperature and the out-vehicle temperature, and the in-vehicle humidity sensor acquires the in-vehicle humidity, and sends the data of the acquired out-vehicle temperature, in-vehicle temperature and in-vehicle humidity to the domain controller of the vehicle. The domain controller of the vehicle calculates the condensation value, and compares the condensation value with the preset condensation threshold and performs a reverse comparison to determine whether the vehicle has a defogging requirement. The preset condensation threshold refers to the maximum value of the set condensation value. If the condensation value exceeds the preset condensation threshold, it is considered that there is a possibility of fogging in the vehicle; if the condensation value does not exceed the preset condensation threshold, it is considered that there is no possibility of fogging in the vehicle.

[0128] Exemplarily, the temperature sensors in the vehicle acquire the in-vehicle temperature and the out-vehicle temperature in real time, and the humidity sensors in the vehicle acquire the in-vehicle humidity in real time; the control system (e.g., controller) in the vehicle obtains the condensation value according to the in-vehicle temperature, out-vehicle temperature and in-vehicle humidity, and compares the condensation value with the preset condensation threshold. In the case where the condensation value is greater than or equal to the preset condensation value, it is determined that the vehicle has a defogging requirement.

[0129] In an embodiment of the present application, according to the acquired out-vehicle temperature, in-vehicle temperature and in-vehicle humidity, the condensation value is obtained according to the out-vehicle temperature, in-vehicle temperature and in-vehicle humidity; if the condensation value is greater than or equal to the preset condensation threshold, it is determined that the vehicle has the defogging requirement; in this solution, by comparing the condensation value with the preset condensation threshold to determine whether the vehicle has a defogging requirement, since the condensation value is calculated according to the temperature difference and humidity, the result of determining whether there is a defogging requirement according to the condensation value is more accurate.

[0130] S230, control the target defogging device to turn on to remove the fog on the inner side of the windshield in the vehicle.

[0131] Exemplarily, before controlling the target defogging device to turn on, the state of the target defogging device needs to be detected; for example, when it is determined that the target defogging device is the air conditioner, it is necessary to detect whether the state of the air conditioner is the normal working state. In the case where it is determined that the state of the air conditioner is the normal working state, turn on the air conditioner.

[0132] In an embodiment of the present application, by turning on the target defogging device, the fog on the inner side of the windshield is removed.

[0133] In one implementation manner, the defogging method further includes:

[0134] If the condensation value is less than the preset condensation threshold, control the target defogging device to turn off.

[0135] After turning on the defogging device, the current condensation value is monitored in real time. In the case where the condensation value is less than the preset condensation threshold, the target defogging device is turned off, where turning off the target defogging device may be turning off the air conditioner or closing the window.

[0136] In addition, after the defogging device is turned on, a preset duration can also be set; after the preset duration has elapsed, the fog area on the inner side of the windshield is recognized. When the recognized fog area on the in-vehicle windshield is 0 or the area is less than a preset area threshold, the target defogging device is automatically turned off. For example, if the set time is 1 minute, then after the defogging device is turned on for one minute, the fog area on the inner side of the windshield is recognized. When the recognized fog area on the in-vehicle windshield is 0 or the area is less than the preset area threshold, the defogging device is turned off; if after the preset duration, the recognized fog area is greater than or equal to the preset area threshold, then the target defogging device continues to be kept in the on state until the fog area is 0 or the area is less than the preset area threshold and the defogging device is turned off.

[0137] It should be noted that the above example uses 1 minute as the preset duration, and the present application does not make any limitation on the size of the preset duration.

[0138] In an embodiment of the present application, when it is detected that the condensation value is less than a preset condensation threshold, the target defogging device is turned off, saving resources during the defogging process, and controlling the target defogging device through a determination condition, realizing the intelligence of removing the fog on the inner side of the windshield in the vehicle.

[0139] In an embodiment of the present application, when it is detected that the vehicle has a defogging requirement, the weather information of the driving environment where the vehicle is located is obtained, and the target defogging device in the vehicle is determined according to different weather information; since the target defogging device in the vehicle is determined based on the weather information of the driving environment where the vehicle is located, compared with the prior art in which the vehicle uses a single defogging device, through this solution, the vehicle can intelligently select the target defogging device to remove the fog on the inner side of the windshield in the vehicle.

[0140] Figure 4 It is a schematic flowchart of another vehicle defogging method provided by an embodiment of the present application.

[0141] Exemplarily, Figure 4 The method 300 shown can be executed by Figure 1 the vehicle 100 shown; or, by Figure 1 the vehicle controller in the vehicle 100 shown; or, by Figure 1 the processor or chip in the vehicle 100 shown; or, it can be executed by Figure 2 the vehicle control system 160 shown.

[0142] Exemplarily, as Figure 4 shown, the method 300 includes the following implementation process:

[0143] S310, the temperature sensor recognizes the outside temperature and the inside temperature of the vehicle, and the humidity sensor recognizes the inside humidity of the vehicle.

[0144] Exemplarily, when it is recognized that the vehicle is exiting the basement, the vehicle controller can control the temperature sensor and the humidity sensor to turn on, and identify the outside temperature, the inside temperature of the vehicle through the temperature sensor, and the inside humidity of the vehicle through the humidity sensor.

[0145] S320. Calculate the condensation value based on the outside temperature, the inside temperature of the vehicle, and the inside humidity of the vehicle.

[0146] Exemplarily, the calculated condensation value is sent to the vehicle control system (Body Control Module, BCM) in the form of a CAN signal.

[0147] Exemplarily, the result of the condensation value is determined by the temperature difference and the inside humidity of the vehicle. The corresponding condensation value can be determined based on the temperature difference and the inside humidity of the vehicle.

[0148] S330. Judge whether the condensation value is greater than the preset condensation threshold.

[0149] Exemplarily, after the vehicle control system determines the condensation value based on the outside temperature, the inside temperature of the vehicle, and the inside humidity of the vehicle, it judges whether the condensation value is greater than the preset condensation threshold.

[0150] Exemplarily, the condensation threshold is jointly determined by the temperature difference and the inside humidity of the vehicle, and the condensation threshold indicates that fog will appear on the inner side of the vehicle's windshield under the corresponding temperature and inside humidity conditions.

[0151] For example, the judgment results between the condensation value and the preset condensation threshold may have the following results: the condensation value is less than the preset condensation threshold, the condensation value is equal to the preset condensation threshold, and the condensation value is greater than the preset condensation threshold.

[0152] Exemplarily, if it is judged that the condensation value is greater than the preset condensation threshold, S330 can be executed.

[0153] S340. Obtain the rain sensor signal and judge whether it is raining or snowing.

[0154] Exemplarily, the rain sensor indicates the rainfall or snowfall in the current driving environment. When the signal collected by the rain sensor is at a high level, it is considered that the current vehicle is in a rainy or snowy weather; when the signal collected by the rain sensor is at a low level, it is considered that the current vehicle is not in a rainy or snowy weather.

[0155] Exemplarily, when it is determined that it is a rainy or snowy weather, S350 is executed; when it is determined that it is not a rainy or snowy weather, S360 is executed.

[0156] S350. Control the air conditioner in the vehicle to turn on the cooling mode.

[0157] Exemplarily, when turning on the air conditioner for cooling, adjust the orientation of the air conditioner towards the windshield, and the air volume and / or temperature of the air conditioner can also be controlled by means of a knob or a soft switch in the vehicle to achieve the effect of defogging.

[0158] Optionally, the implementation manner of the above S350 can refer to Figure 3 the relevant description in S220 in

[0159] S360, control the window in the vehicle to open.

[0160] Exemplarily, the above control of the window opening may refer to controlling the window in the vehicle to start descending from the current state.

[0161] Optionally, after executing S350 and S360, the outdoor temperature, the indoor temperature and the indoor humidity value can be continuously obtained in real time through the temperature sensor and the humidity sensor; calculate the condensation value through the outdoor temperature, the indoor temperature and the indoor humidity value; in the case where the condensation value is less than the preset condensation threshold, execute S370.

[0162] Optionally, the implementation manner of the above S360 can refer to Figure 3 the relevant description in S220 in

[0163] In one example, in order to remove the fog on the inner side of the vehicle, different defogging methods can be selected according to whether there is a user in the vehicle.

[0164] Regarding the scenario where there is no user in the vehicle: In the case where there is no user in the vehicle, control the window of the vehicle to open, which saves energy consumption while removing the fog on the inner side of the window.

[0165] Regarding the scenario where there is a user in the vehicle: When there is a user in the vehicle, it is necessary to determine whether the speed of the vehicle is greater than a preset speed threshold. When it is detected that the speed of the vehicle is greater than the preset speed threshold, it indicates that the vehicle is traveling at a high speed. Since there is relatively high noise and strong outside wind when the vehicle is traveling at a high speed, if the window is opened for defogging, it will affect the user's ride. Therefore, control the vehicle's window to close and control the vehicle's air conditioner to turn on. When it is detected that the speed of the vehicle is less than the preset speed threshold, it indicates that the vehicle is traveling at a low speed, which means that the outside environmental factors will not affect the user after the window is opened. Therefore, the vehicle's window can be controlled to open to remove the fog on the inner side of the window. Further, when there is a user in the vehicle and the vehicle is traveling at a low speed, the defogging method is specifically selected according to the weather information. For example, when there is a user in the vehicle and the speed of the vehicle is less than the preset threshold, it is determined whether the current weather is rainy or snowy. When the current weather is rainy or snowy, control the air conditioner in the vehicle to turn on to prevent rain or snow from getting on the user after the window is opened, which affects the user's ride. When the current weather is not rainy or snowy, control the vehicle's window to open to save energy consumption while removing the fog on the inner side of the window. In addition, when the vehicle is traveling at a low speed and there is a user in the vehicle, and according to whether the current weather is rainy or snowy, it is also necessary to select a specific defogging method according to the direction of the vehicle's travel and the wind direction. For example, the vehicle is traveling from south to north, the current weather is rainy, and the wind is blowing from the west. When the west wind is blowing, if the left window of the vehicle is opened, the wind will blow the rain onto the left window of the vehicle and get on the user. While opening the right window, a small amount of rainwater may enter the vehicle through the right window, or the rainwater may not enter the vehicle through the right window. Therefore, it is necessary to open the right window of the vehicle to achieve defogging. If the rainfall is large, control the opening degree of the right window to be small. If the rainfall is small, the right window can be controlled to open fully.

[0166] S370, control the target defogging device to close.

[0167] Exemplarily, when the target defogging device is the air conditioner in the vehicle, control the air conditioner in the vehicle to close; when the target defogging device is the window in the vehicle, control the window in the vehicle to close.

[0168] Optionally, the implementation method of the above S370 can refer to Figure 3 the relevant description in S230 in

[0169] In an embodiment of the present application, the in-vehicle temperature and the out-vehicle temperature are obtained through a temperature sensor, and the in-vehicle humidity is obtained through a humidity sensor; a temperature difference is obtained based on the in-vehicle temperature and the out-vehicle temperature, and a condensation value is calculated based on the temperature difference and the in-vehicle humidity, so that the result of the obtained condensation value is more accurate; the condensation value is compared with a preset condensation value, and in the case where the condensation value does not reach the preset condensation value, the target defogging device is controlled to close, making the control of the target defogging device more intelligent; in the case where the condensation value reaches the preset condensation value, the information of a rain sensor is obtained, it is determined whether it is raining or snowing, and in the case of raining or snowing, the air conditioner in the vehicle is controlled to turn on the cooling mode to remove the fog on the inner side of the windshield in the vehicle; in the case of determining that it is not raining or snowing, the vehicle window is controlled to lower, achieving the removal of the fog on the inner side of the windshield in the vehicle on the premise of saving the power consumption of the vehicle.
