[0027] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0028] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0029] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0030] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0031] When the vehicle is parked or driving, when the temperature difference between the inside and outside of the window is large or the humidity in the air is high, the water vapor in the air will condense into water droplets when it encounters the lower temperature glass surface and adhere to the glass surface, forming fog.

[0032] At present, the defog function of the vehicle air conditioner is generally used to remove fog. The vehicle air conditioner can use the cold air mode or the warm air mode for defog. The cold air mode accelerates the flow of air inside the vehicle, causing the water droplets to evaporate quickly, thereby removing the fog on the vehicle windshield, thereby achieving the defog effect. The warm air mode increases the air temperature inside the vehicle, causing the water droplets to evaporate quickly, thereby removing the fog on the vehicle windshield, thereby achieving the defog effect.

[0033] To facilitate understanding, a specific application scenario is first exemplified below.

[0034] See also Figure 1 , is a schematic diagram of an application scenario provided by an embodiment of the present application. Figure 1 As shown, the vehicle 100 includes a controller 101, an air conditioner 102 and a wiper 103. The controller 101 can be used to send relevant control instructions to control the air conditioner 102 and the wiper 103 to perform operations corresponding to the relevant control instructions. The air conditioner 102 generally includes a cold air mode and a warm air mode. The air conditioner 102 can start the cold air mode or the warm air mode to perform defog according to the received relevant control instructions. The wiper 103 can perform a wiping operation to perform defog according to the received relevant control instructions.

[0035] However, in different application scenarios, using a defog mode that does not match the application scenario may result in a poor user experience. For example, when the outside of the car window is fogged, if the air conditioner is used for defog, the defog efficiency may be low, affecting the user's driving experience. When the vehicle is driving in winter, if the air conditioner's cold air mode is used for defog, the temperature inside the vehicle may become lower, affecting the user's riding experience in winter.

[0036] In view of the above problems, in the embodiment of the present application, the vehicle interior environment temperature, vehicle interior environment humidity, vehicle exterior environment temperature and vehicle exterior environment humidity are first obtained; then the vehicle interior dew point temperature is determined according to the vehicle interior environment temperature and vehicle interior environment humidity; when the vehicle exterior environment temperature is lower than the vehicle interior dew point temperature, the first defog mode is used for defog; when the vehicle exterior environment humidity is higher than the humidity threshold, the second defog mode is used for defog. In other words, the defog mode matching the application scenario can be determined according to the application scenario, and then the defog mode matching the application scenario is used for defog to improve the user experience.

[0037] Specifically, a detailed description is given below in conjunction with the accompanying drawings and specific embodiments.

[0038] See also Figure 2 , is a flow chart of a vehicle defogging method provided in an embodiment of the present application. The method can be applied to Figure 1 The controller in the application scenario shown is Figure 2 As shown, it mainly includes the following steps.

[0039] Step S201: Acquire the vehicle interior environment temperature, vehicle interior environment humidity, vehicle exterior environment temperature and vehicle exterior environment humidity.

[0040] For the sake of convenience, ambient temperature and humidity are used to represent the vehicle's internal ambient temperature, the vehicle's internal ambient humidity, the vehicle's external ambient temperature and the vehicle's external ambient humidity.

[0041] In the embodiment of the present application, the demisting mode matching the application scenario corresponding to the ambient temperature and humidity can be determined according to the ambient temperature and humidity. Therefore, before determining the demisting mode matching the application scenario, it is necessary to obtain the ambient temperature and humidity.

[0042] In a possible implementation, the vehicle interior environment temperature, the vehicle interior environment humidity, the vehicle exterior environment temperature, and the vehicle exterior environment humidity may be acquired through a network and / or sensors.

[0043] In the embodiment of the present application, the controller can obtain part or all of the data of the ambient temperature and humidity through the vehicle-mounted network terminal (Telematics BOX, TBOX). The sensor can be a sensor in an integrated vehicle body control system. The controller can also obtain part or all of the data of the ambient temperature and humidity in real time according to the sensor.

[0044] It should be pointed out that in practical applications, technicians in this field can also obtain the ambient temperature and humidity in other ways according to actual needs, and this application does not impose any specific restrictions on this.

[0045] In addition, in a possible implementation, a wake-up time interval can be set for TBOX to collect and analyze the ambient temperature and humidity, and then determine whether defogging is required. This can avoid a long wake-up time for TBOX and reduce energy consumption to a certain extent.

[0046] Step S202: Determine the dew point temperature inside the vehicle according to the vehicle interior ambient temperature and the vehicle interior ambient humidity.

[0047] The dew point temperature in the car refers to the temperature when the air is cooled to saturation while the water vapor content in the air inside the vehicle remains unchanged and the air pressure remains constant. It can be understood that the dew point temperature in the car is the temperature when the water vapor in the air turns into water droplets.

[0048] In practical applications, a dew point meter can be used to measure the dew point temperature inside a vehicle. However, the accuracy and sensitivity of the dew point meter decrease at low temperatures, and the dew point meter has high requirements on the technical level of the operator. Operation errors or improper maintenance may lead to inaccurate measurement results. In addition, it is very inconvenient to use a dew point meter to measure the dew point temperature inside a vehicle.

[0049] Therefore, in a possible implementation, a more accurate in-vehicle dew point temperature can be simply and quickly calculated based on the vehicle's internal ambient temperature and the vehicle's internal ambient humidity.

[0050] Step S203: When the ambient temperature outside the vehicle is lower than the dew point temperature inside the vehicle, a first defog mode is used for defog, wherein the first defog mode is to perform defog through air conditioning.

[0051] When the ambient temperature outside the vehicle is lower than the dew point temperature, the water vapor in the air inside the vehicle will condense into water droplets when it encounters the lower temperature glass surface, forming fog. The formed fog will block the user's vision, making it impossible for the user to accurately identify the driving road conditions, posing a safety hazard.

[0052] In an embodiment of the present application, when the controller described above determines that the interior of the vehicle needs to be defogged based on the external ambient temperature of the vehicle and the dew point temperature inside the vehicle, it can send relevant control instructions to the air conditioner to start the air conditioner for defogger.

[0053] It should be pointed out that when defogging through air conditioning, you can use the cold air mode or the warm air mode for defog. When using a defog mode that does not match the application scenario in different application scenarios, it may lead to a poor user experience. For example, when the vehicle is driving in summer, if the warm air mode of the air conditioner is used for defog, the temperature inside the car may become higher, affecting the user's riding experience in summer. When the vehicle is driving in winter, if the cold air mode of the air conditioner is used for defog, the temperature inside the car may become lower, affecting the user's riding experience in winter.

[0054] Therefore, in a possible implementation, when the vehicle's external ambient temperature is lower than the vehicle's internal dew point temperature and the vehicle's external ambient temperature is higher than a temperature threshold, the first sub-mode in the first defog mode is used for defog. The first sub-mode is to defog using the cold air mode of the air conditioner.

[0055] In the embodiment of the present application, the temperature threshold can be considered as a temperature value of seasonal changes, which is used to determine the current season. A temperature threshold can be preset. Exemplarily, the temperature threshold can be 10°C, 12°C, 14°C, 15°C, 20°C, etc.

[0056] It should be pointed out that in practical applications, those skilled in the art may also determine the temperature threshold in other ways according to actual needs, and this application does not impose any specific restrictions on this.

[0057] In an embodiment of the present application, when the ambient temperature outside the vehicle is greater than a temperature threshold, it can be considered that the current season is summer; when the ambient temperature outside the vehicle is less than the temperature threshold, it can be considered that the current season is winter.

[0058] Exemplarily, the temperature threshold is 15°C. When the vehicle's external ambient temperature is 20°C, since 20°C>15°C, that is, the vehicle's external ambient temperature is greater than the temperature threshold, it can be considered that the current season is summer; when the vehicle's external ambient temperature is 10°C, since 10°C<15°C, that is, the vehicle's external ambient temperature is less than the temperature threshold, it can be considered that the current season is winter.

[0059] As described above, when the vehicle's external ambient temperature is lower than the vehicle's internal dew point temperature and the vehicle's external ambient temperature is greater than the temperature threshold, it can be considered that the vehicle is driving in summer and the vehicle interior needs to be defogged. At this time, the controller can control the air conditioner to use the cold air mode for defog.

[0060] In an embodiment of the present application, when the vehicle is driving in summer and the interior of the vehicle needs to be defogged, the cold air mode of the air conditioner can be used for defog. On the one hand, the cold air mode of the air conditioner can adjust the air temperature inside the vehicle to a more comfortable temperature, which improves the user experience to a certain extent. On the other hand, the cold air mode of the air conditioner can speed up the flow of air inside the vehicle, causing water droplets to evaporate quickly, thereby removing the fog on the vehicle windshield, thereby achieving a defog effect. In addition, through the condensation effect of the air conditioner, the air humidity inside the vehicle can be reduced to avoid fogging again.

[0061] Preferably, in a possible implementation, in the first sub-mode, in addition to defoggering through the cold air mode of the air conditioner, the internal circulation mode needs to be turned on. That is, the first sub-mode is defoggering through the cold air mode of the air conditioner and turning on the internal circulation mode.

[0062] The internal circulation mode means that when the vehicle's internal air circulates in operation, the air outside the vehicle will not enter the vehicle.

[0063] In the embodiment of the present application, the cold air mode and internal circulation mode of the air conditioner can be used to speed up the flow of air inside the vehicle, allowing water droplets to evaporate quickly and achieve a faster defog effect.

[0064] As mentioned above, when a vehicle is driving in winter, if a defog mode that is not suitable for driving in winter is used, the user experience may be affected.

[0065] Therefore, in a possible implementation, when the ambient temperature outside the vehicle is lower than the dew point temperature inside the vehicle and the ambient temperature outside the vehicle is lower than the temperature threshold, the second sub-mode in the first defog mode is used for defog. The second sub-mode is to defog by the warm air mode of the air conditioner.

[0066] In other words, when the vehicle's external ambient temperature is lower than the vehicle's internal dew point temperature and the vehicle's external ambient temperature is lower than the temperature threshold, it can be considered that the vehicle is driving in winter and the vehicle interior needs to be defogged. At this time, the controller can control the air conditioner to use the warm air mode for defog.

[0067] In the embodiment of the present application, when the vehicle is driving in winter and the interior of the vehicle needs to be defogged, the warm air mode of the air conditioner can be used for defog. On the one hand, the warm air mode of the air conditioner can adjust the air temperature inside the vehicle to a more comfortable temperature, which improves the user experience to a certain extent. On the other hand, the warm air mode of the air conditioner can increase the air temperature inside the vehicle, promote the evaporation of water droplets, and then remove the fog on the vehicle windshield, thereby achieving a defog effect.

[0068] Preferably, in a possible implementation, in the second sub-mode, in addition to defoggering through the warm air mode of the air conditioner, the external circulation mode needs to be turned on. That is, the second sub-mode is defoggering through the warm air mode of the air conditioner and turning on the external circulation mode.

[0069] The external circulation mode means that the air conditioner circulates with the air outside the vehicle, and the air outside the vehicle enters the vehicle for circulation.

[0070] In the embodiment of the present application, the air flow speed inside the vehicle can be accelerated by the warm air mode and the external circulation mode of the air conditioner, so that the water droplets can evaporate quickly and achieve a faster defogging effect. Fresh air outside the vehicle can also be introduced to improve the air quality inside the vehicle, thereby improving the user experience to a certain extent.

[0071] Step S204: When the humidity of the environment outside the vehicle is greater than the humidity threshold, the second defog mode is used for defog, and the second defog mode is to defog by wipers.

[0072] In the embodiment of the present application, the humidity threshold value can be considered as the humidity value at which water vapor in the air easily condenses into water droplets. A humidity threshold value can be preset. Exemplarily, the temperature threshold value can be 20%, 25%, 30%, 35%, 40%, 45%, etc.

[0073] It should be pointed out that, in practical applications, those skilled in the art may also determine the humidity threshold in other ways according to actual needs, and this application does not impose any specific restrictions on this.

[0074] In an embodiment of the present application, when the humidity of the environment outside the vehicle is greater than the humidity threshold, it can be considered that there is a risk of fogging outside the vehicle and defogger is required; when the humidity of the environment outside the vehicle is less than the humidity threshold, it can be considered that there is no risk of fogging outside the vehicle and defogger is not required.

[0075] For example, the humidity threshold is 50%. When the humidity outside the vehicle is 60%, since 60%>50%, that is, the humidity outside the vehicle is greater than the humidity threshold, it can be considered that there is a risk of fogging outside the vehicle and defogger is required; when the humidity outside the vehicle is 40%, since 40%<50%, that is, the humidity outside the vehicle is less than the humidity threshold, it can be considered that there is no risk of fogging outside the vehicle and defogger is not required.

[0076] As described above, when the humidity of the environment outside the vehicle is greater than the humidity threshold, there is a risk of fogging outside the vehicle, and defogger is required. At this time, the controller can control the wiper to defog.

[0077] In the embodiment of the present application, the exterior of the vehicle can be quickly defogged by wipers, which helps to avoid the impact of fogging on the exterior of the vehicle on the user's driving vision, thereby improving the user experience to a certain extent.

[0078] In the embodiment of the present application, the vehicle interior environment temperature, vehicle interior environment humidity, vehicle exterior environment temperature and vehicle exterior environment humidity are first obtained; then the vehicle interior dew point temperature is determined according to the vehicle interior environment temperature and vehicle interior environment humidity; when the vehicle exterior environment temperature is lower than the vehicle interior dew point temperature, the first defog mode is used for defog; when the vehicle exterior environment humidity is higher than the humidity threshold, the second defog mode is used for defog. In other words, the defog mode matching the application scenario can be determined according to the application scenario, and then the defog mode matching the application scenario is used for defog to improve the user experience.

[0079] For ease of understanding, the method described in the embodiment of the present application is described in detail below in conjunction with a specific implementation method.

[0080] See also Figure 3 , is a flow chart of another vehicle defogging method provided in an embodiment of the present application. The method can be applied to Figure 1 The controller in the application scenario shown is Figure 3 It mainly includes the following steps.

[0081] Step S301: Acquire the vehicle interior environment temperature, vehicle interior environment humidity, vehicle exterior environment temperature and vehicle exterior environment humidity.

[0082] Step S302: Determine the dew point temperature inside the vehicle according to the vehicle interior ambient temperature and the vehicle interior ambient humidity.

[0083] Step S303: Determine whether the ambient temperature outside the vehicle is lower than the dew point temperature inside the vehicle. If the ambient temperature outside the vehicle is lower than the dew point temperature inside the vehicle, execute step S304.

[0084] Step S304: adopting the first defog mode to perform defog.

[0085] Step S305: Determine whether the vehicle's external environment is greater than a temperature threshold. If the vehicle's external environment is greater than the temperature threshold, execute step S306; otherwise, execute step S307.

[0086] Step S306: Demisting is performed using the first sub-mode in the first demisting mode.

[0087] Step S307: Demisting is performed using the second sub-mode in the first demisting mode.

[0088] Step S308: Determine whether the humidity of the environment outside the vehicle is greater than a humidity threshold. If the humidity of the environment outside the vehicle is greater than the humidity threshold, execute step S309.

[0089] Step S309: adopting the second defog mode to perform defog.

[0090] For specific contents involved in the examples in the implementation of this application, please refer to the above Figure 2 The description in the illustrated embodiment will not be repeated for the sake of brevity.

[0091] In the embodiment of the present application, in order to meet the user's demisting needs, the user can also independently select the corresponding demisting mode for demisting according to actual needs. Specifically, when the user wants to demist the vehicle, the demisting mode selection instruction can be triggered, and the controller uses the demisting mode matching the demisting mode selection instruction to perform demisting according to the demisting mode selection instruction triggered by the user.

[0092] In actual applications, after entering the vehicle, the user can directly trigger the defog mode selection command through the controller to perform defog. However, when the user expects to defog the vehicle before entering the vehicle, if the defog mode selection command is triggered through the controller to perform defog, the user still needs to enter the vehicle first, which not only wastes time but is also relatively troublesome for the user.

[0093] Therefore, in a possible implementation, the user may send a defog mode selection instruction to the controller through the user device. The controller performs defog according to the received defog mode selection instruction using a defog mode that matches the defog mode selection instruction.

[0094] In an embodiment of the present application, a user triggers a defog mode selection instruction through a user device, which can remotely control the vehicle to defog, thereby improving the user experience.

[0095] In addition, the user may expect to know the defog status at any time, and determine whether to continue defog according to the defog status. Therefore, in a possible implementation, the controller can detect the defog status and send the defog status to the user device, and the defog status is used to characterize the defog effect. In other words, the user can choose whether to trigger the defog mode selection instruction and perform defog according to the defog status received by the user device.

[0096] Furthermore, in a possible implementation, the controller may send environmental data to the user device in addition to the defog status.

[0097] In an embodiment of the present application, environmental data includes but is not limited to vehicle interior ambient temperature, vehicle interior ambient humidity, vehicle exterior ambient temperature, vehicle exterior ambient humidity, air quality, wind level, season, etc.

[0098] It should be pointed out that after the user device receives the defog effect and / or environmental data sent by the controller, the defog effect and / or environmental data can be displayed to the user through voice broadcast, page display, etc., which is beneficial for the user to understand the current defog effect and / or environmental data of the vehicle at any time, and can also provide a basis for the user to determine whether to defog the vehicle.

[0099] In the embodiment of the present application, the user can trigger the defog mode selection instruction and independently select the corresponding defog mode for defog, thereby improving the user experience.

[0100] For ease of understanding, the method described in the embodiment of the present application is described in detail below in conjunction with a specific implementation method.

[0101] See also Figure 4 , is a flow chart of another vehicle defogging method provided in an embodiment of the present application. Figure 4 As shown, this method Figure 2 Based on the illustrated embodiment, the following steps are also included.

[0102] Step S401: The controller detects the current defog status.

[0103] In the embodiment of the present application, the defog state is used to characterize the defog effect. The controller can detect the current defog state of the vehicle through the vehicle-mounted network terminal or the integrated body control system.

[0104] Step S402: The controller sends the defog status to the user equipment.

[0105] In the embodiment of the present application, the user equipment may be a mobile phone, a tablet computer, etc. It should be noted that the user equipment may also be other devices, and the present application does not make any specific restrictions on this.

[0106] In the embodiment of the present application, after the controller detects the current defog state, it will send the detected defog state to the user device. After the user device receives the defog state sent by the controller, it can display the defog effect to the user through voice broadcast, page display, etc., which is helpful for the user to understand the current defog state of the vehicle at any time, and can also provide a judgment basis for the user to determine whether to defog the vehicle.

[0107] Furthermore, the controller can also send environmental data to the user device, which is beneficial for the user to understand the environmental conditions at any time, and can also provide more judgment basis for the user to determine whether to defog the vehicle.

[0108] Step S403: The user triggers a defog mode selection instruction on the user device.

[0109] In the embodiment of the present application, when the user device receives the defog status sent by the controller, the user can determine whether the vehicle needs to be defogged according to the defog status received by the user device, and then choose whether to trigger the defog mode selection instruction. When the user wants to defog the vehicle, the defog mode selection instruction can be triggered on the user device.

[0110] Step S404: the user equipment sends a defog mode selection instruction to the controller.
