[0002] In winter, especially in northern regions, the outdoor temperature is extremely low, and indoor parking lots (such as underground parking lots in residential areas) generally have heating equipment, which leads to large differences in temperature and humidity between indoors and outdoors.

[0081] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0082] Figure 1 is a flow chart of a vehicle window heating control method according to an embodiment of the present application;

[0085] Step 2: Determine whether the vehicle's external temperature is lower than the preset value. If so,

[0086] Step 3: Obtain basic information of the vehicle and the location to be entered;

[0087] Step 4: Determine whether window heating is required based on the basic information of the vehicle and the information of the place to be entered. If so, generate a window heating signal and send it to the window heating device.

[0088] The vehicle window heating control method of the present application has the following advantages:

[0089] 1. Without increasing component costs, the system can automatically turn on the window heating function in advance by intelligently identifying when a vehicle is about to enter a parking space with a large temperature difference from the outdoor environment, without the need for manual control by the driver;

[0090] 2. Effectively prevent the fogging of car windows due to large temperature differences when entering parking spaces, avoid vehicle scratches caused by fogging of car windows obstructing the driver's vision, and improve vehicle safety performance;

[0091] 3. After the window heating is turned on, the fogging conditions of the current environment are judged in real time. When the fogging conditions are not met, the window heating function is disconnected in advance to save energy.

[0092] In this embodiment, the basic vehicle information includes vehicle location information and vehicle driving information;

[0093] Specifically, judging whether window heating is required based on basic vehicle information and information of the place to be entered includes:

[0094] The vehicle position information is obtained through the navigation information, and the vehicle driving information is obtained according to the various sensors of the vehicle. It can be understood that the vehicle driving information includes the vehicle speed information; the vehicle navigation information can also obtain the location of the place to be entered. After knowing the location of the place to be entered, the location of the vehicle and the vehicle speed information, the time information required to reach the destination can be calculated. If the required time information t is less than or equal to the preset time threshold t0, then

[0095] Generates a signal for window heating.

[0096] In this embodiment, the basic vehicle information further includes window temperature information;

[0097] Before generating the window heating signal, judging whether the window heating is required according to the basic information of the vehicle and the information of the place to be entered further includes:

[0098] Acquire a preset place to be entered database, the preset place to be entered database includes at least one preset place to be entered information and temperature group information corresponding to each preset place to be entered information, each temperature group information includes at least one date threshold and a preset temperature corresponding to each date threshold;

[0099] Get the current vehicle date;

[0100] Determine whether the current vehicle date is within a date threshold. If so,

[0101] Get the preset temperature corresponding to the date threshold;

[0102] Determine whether the difference between the window temperature information and the preset temperature is greater than the preset temperature threshold. If so,

[0103] Generates a signal for window heating.

[0104] For example, we can collect data in advance on various places that vehicles often go to. For example, if vehicles often go to the underground parking lot of a stadium, we can collect the temperature of the underground parking lot. For example, we can collect the temperature of the underground parking lot once a month. Of course, we can also collect it once a day.

[0105] The collected temperatures of each place to be entered are put into the preset place to be entered database.

[0106] When the vehicle performs the method of the present application, the vehicle can learn about the information of the place it is about to enter through the navigation system. Assuming that the place to be entered is the underground parking lot of the above-mentioned gymnasium, the current vehicle date is obtained. For example, today is January 8th. Assuming that in this embodiment, the temperature of the underground parking lot is collected once a month, the date threshold can be January 1st to January 31st. The preset temperature corresponding to the date threshold is obtained. Assuming that the temperature is 25 degrees, and the vehicle's window temperature is 10 degrees, assuming that the preset temperature threshold is 10 degrees, it is obvious whether the difference between the window temperature information and the preset temperature is greater than the preset temperature threshold, then it is considered that heating is required.

[0107] In actual vehicle driving, on the one hand, it takes a certain amount of time to heat the vehicle, and the temperature inside the vehicle cannot rise quickly just by turning on the heating. On the other hand, in order to prevent fogging, the heating is best performed before the temperature is converted. By adopting the above method, it is possible to determine whether to heat by estimating the temperature of the place to be entered, and to perform heating in advance when it is determined that heating is needed, thereby achieving a driver's imperceptible conversion and avoiding the delay effect caused by heating after entering the place to be entered and fogging.

[0108] In this embodiment, the basic vehicle information further includes vehicle communication connection information;

[0109] Judging whether window heating is required based on basic vehicle information and information about the place to be entered includes:

[0110] Obtain the terminal device information that establishes a communication connection with the vehicle. If the terminal device information is the same as the terminal device information of the place to be entered in the preset place to be entered database, then

[0111] Generate a window heating signal;

[0112] Specifically, in this embodiment, after the vehicle enters the communication connection range of the parking lot, the V2X function implemented by T-BOX is used, that is, the vehicle automatically establishes a communication connection with the intelligent parking lot terminal device. T-BOX obtains information about the vehicle entering the parking lot through intelligent communication means, and determines whether the windows need to be heated based on the basic information of the vehicle and the parking lot information.

[0113] In this embodiment, before generating the window heating signal, judging whether the window heating is required according to the basic information of the vehicle and the information of the place to be entered further includes:

[0114] Acquire a preset place to be entered database, the preset place to be entered database includes at least one preset place to be entered information and temperature group information corresponding to each preset place to be entered information, each temperature group information includes at least one date threshold and a preset temperature corresponding to each date threshold;

[0115] Get the current vehicle date;

[0116] Determine whether the current vehicle date is within a date threshold. If so,

[0117] Get the preset temperature corresponding to the date threshold;

[0118] Determine whether the difference between the window temperature information and the preset temperature is greater than the preset temperature threshold. If so,

[0119] Generates a signal for window heating.

[0120] In this embodiment, the basic vehicle information further includes image information from a vehicle-mounted camera;

[0121] Get the image information from the vehicle camera;

[0122] Acquire feature information of the image information according to the image information;

[0123] According to the feature information, search in the preset database of places to be entered to see if there is matching image information. If so,

[0124] Generates a signal for window heating.

[0125] For example, in this embodiment, based on the image information obtained by the front camera of the vehicle, feature information of the image information is extracted, the feature information is matched with the image information in the built-in database, the same entrance to the parking lot is found, and when the front camera recognizes that the vehicle begins to enter the parking lot, a window heating signal is generated.

[0126] In this embodiment, before generating the window heating signal, judging whether the window heating is required according to the basic information of the vehicle and the information of the place to be entered further includes:

[0127] Acquire a preset place to be entered database, the preset place to be entered database includes at least one preset place to be entered information and temperature group information corresponding to each preset place to be entered information, each temperature group information includes at least one date threshold and a preset temperature corresponding to each date threshold;

[0128] Get the current vehicle date;

[0129] Determine whether the current vehicle date is within a date threshold. If so,

[0130] Get the preset temperature corresponding to the date threshold;

[0131] Determine whether the difference between the window temperature information and the preset temperature is greater than the preset temperature threshold. If so,

[0132] Generates a signal for window heating.

[0133] In this embodiment, the information of the place to be entered includes temperature information of the place to be entered;

[0134] Judging whether window heating is required based on basic vehicle information and information of the place to be entered also includes:

[0135] Obtaining vehicle exterior temperature information of the vehicle at a first time point;

[0136] Acquire vehicle exterior temperature information at a second time point after the first time point;

[0137] Determine whether the difference between the vehicle exterior temperature information at a first time point and the vehicle exterior temperature information at a second time point exceeds a preset threshold, and if so, obtain first vehicle exterior temperature information at a time point before the first time point;

[0138] Acquire second temperature information outside the vehicle at a time point after the second time point;

[0139] calculating the fogging temperature according to second temperature information outside the vehicle at a time point after the second time point;

[0140] Determine whether the first temperature information outside the vehicle at a time point before the first time point is less than or equal to the fogging temperature, if so, then

[0141] Generates a signal for window heating.

[0142] Specifically, when the vehicle's outside temperature at the second time point is greater than the vehicle's outside temperature at the first time point, it is judged that the vehicle's outside temperature information has changed suddenly. At this time, the first temperature information at a time point before the first time point is obtained, and the second temperature information at a time point after the second time point is obtained. The fogging temperature is calculated based on the second temperature information, and then it is judged whether the first temperature information is less than or equal to the fogging temperature. If so, the window heating is turned on.

[0143] For example, in this embodiment, when the temperature outside the vehicle is -10°C at the first time point 9:08:55 and is 2°C at the second time point 9:09:10, it is determined that the temperature outside the vehicle changes suddenly, and it is determined that the vehicle may enter a parking lot with a large temperature difference from the outdoor temperature from the outdoor temperature. At this time, the first temperature information of -11°C at a time point 9:07:40 before the first time point and the second temperature information of 3°C at a time point 9:09:30 after the second time point are obtained;

[0144] Calculate the dew point temperature T of the current vehicle exterior environment based on the second temperature information 3°C d , dew point temperature T d The calculation formula is as follows:

[0145]

[0146]

[0147]

[0148] Among them, T d = dew point temperature, T 第二温度 = a second temperature at a time point after the second time point at 9:09:30, rh = humidity, e = vapor pressure, es = saturated vapor pressure;

[0149] According to the dew point temperature T d Get the fogging temperature, fogging temperature = dew point temperature T d -2;

[0150] If the first temperature information outside the vehicle before the first time point is less than or equal to the fogging temperature, a window heating signal is generated.

[0151] In this embodiment, the vehicle window heating control method further includes:

[0152] After generating the heating signal, the heating time is recorded;

[0153] After determining that the vehicle window heating is required and before generating the vehicle window heating signal, the vehicle window heating control method further includes:

[0154] Get the working status of the vehicle heating device;

[0155] Determining whether the vehicle window is in a heating state according to the working state of the vehicle heating device, and if not, turning on the vehicle window heating and recording the heating time;

[0156] If the vehicle heating device is in the window heating state, it is determined whether the window heating trigger source is the driver's active triggering of heating. If so, the window is controlled to continue heating; if not actively turned on by the driver, the window is controlled to continue heating and the timing is reset.

[0157] In this embodiment, the vehicle window heating control method further includes:

[0158] Calculate the window heating time based on the window heating time;

[0159] Determine whether the window heating time exceeds the preset heating time, and if so, obtain the window temperature;

[0160] Determine whether the difference between the window temperature and the vehicle's exterior temperature is less than a preset difference. If so, stop heating the window.

[0161] If the difference between the window temperature and the outside ambient temperature is greater than the preset difference, the window heating will continue until the preset thermal protection time and then stop;

[0162] If the window heating signal is followed by a driver-triggered window heating off operation or a vehicle ignition off signal, the window heating is stopped.

[0163] In this embodiment, the vehicle window heating control method further includes:

[0164] When the window heating signal is generated, the window heating device starts heating and feeds back the heating status, updates and stores the heating trigger source status, and displays a heating icon on the instrument panel according to the heating status, prompting the driver that the window is in the heating state.
