[0033] It should be understood that when used in the specification and appended claims of the present application, the term "comprising" indicates the presence of the described features, wholes, steps, operations, elements, and / or components, but does not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components, and / or their combinations.

[0034] In addition, in the description of the specification and appended claims of the present application, the terms "first", "second", "third", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0035] References to "one embodiment" or "some embodiments" etc. described in the specification of this application mean that specific features, structures, or characteristics described in connection with that embodiment are included in one or more embodiments of this application. Thus, statements such as "in one embodiment", "in some embodiments", "in other some embodiments", "in still other embodiments", etc. that appear in different places in this specification do not necessarily all refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "comprising", "including", "having" and their variants all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0036] Electrochromic glass refers to the phenomenon that the optical properties (reflectivity, transmittance, absorptivity, etc.) of glass materials undergo stable and reversible color changes under the action of an external electric field, which is manifested as reversible changes in color and transparency in appearance.

[0037] Currently, the application of electrochromic glass in the automotive field is relatively rare. The method for adjusting the vehicle interior environment proposed in this application reduces the probability of sunlight shining into the vehicle through the color change of the electrochromic glass on the vehicle, achieving the effect of improving the comfort of the vehicle interior environment by using electrochromic glass.

[0038] Figure 1 A vehicle provided for an embodiment of this application, the vehicle includes: an electronic device 10, a battery device 20, a blower 30, a condenser 40, and a subcooler 50.

[0039] In this embodiment, the battery device 20 supplies power to the devices that need electricity in the vehicle. The battery device 20 includes a solar component and a backup battery. The solar component may include a solar skylight, a solar device provided on the vehicle roof, etc. The backup battery is used to supply power to the devices in the vehicle when the power supply of the solar component in the vehicle is insufficient, or to store the excess power in the solar component when the power supply of the solar component is abundant.

[0040] In this embodiment, the blower 30 is used for exchanging air inside and outside the vehicle to achieve the effect of cooling the vehicle interior. Specifically, the air inlet of the blower 30 may be disposed opposite to the exhaust grille on the vehicle.

[0041] In this embodiment, the condenser 40 is a component of the refrigeration system and belongs to a type of heat exchanger. It can convert a gas or vapor into a liquid and transfer the heat in the pipe to the air near the pipe in a very fast manner. The subcooler 50 uses the low-temperature gas from the upper tower to cool the saturated liquid from the lower tower, so that its temperature is reduced to below the saturation temperature.

[0042] A refrigerant, also known as a refrigerant medium or a refrigerant, is a medium substance through which various heat engines complete energy conversion.

[0043] The condenser 40 and the subcooler 50 are connected in series through pipelines. The refrigerant in the condenser 40 flows into the interior of the subcooler 50 from the outlet of the condenser 40, and the refrigerant entering the subcooler 50 flows out from the outlet of the subcooler 50 after being cooled or not cooled by the subcooler 50. When the subcooler 50 is in an operating state, it can perform secondary cooling on the refrigerant flowing out of the condenser 40. A first sensor can be provided at the outlet of the condenser 40, and the first sensor is used to detect the parameter values of the refrigerant at that location. Specifically, the parameter values can include pressure values and temperature values.

[0044] In this embodiment, at least one of the front window glass, rear window glass, front windshield, and rear windshield on the vehicle is an electrochromic glass. The electrochromic glass is in a transparent state when not powered on and can turn into a grayscale state when powered on. The grayscale of the electrochromic glass can be adjusted according to the magnitude of the current. The greater the current passing through the electrochromic glass, the darker the color of the electrochromic glass. The smaller the current passing through the electrochromic glass, the lighter the color of the electrochromic glass.

[0045] In this embodiment, the electronic device 10 can include an air-conditioning control unit, a processor, an intelligent fuse box with a communication function, a central control screen, etc. The air-conditioning control unit is used to control the air conditioner. The processor determines whether the air conditioner is enabled by monitoring the air-conditioning control unit. The intelligent fuse box is respectively connected to the subcooler, the backup battery, each electrochromic glass, and the blower. The processor sends control instructions to the intelligent fuse box, and the intelligent fuse box sends the control instructions to the corresponding devices. The central control screen is a human-machine interaction device, and the central control screen is used to collect the user's instructions and send the user's instructions to the processor. Specifically, the control of the in-vehicle devices by the processor can refer to the specific introduction in the following method for adjusting the vehicle interior environment, which will not be elaborated here.

[0046] In this embodiment, an external light intensity sensor, an internal light intensity sensor, an external temperature sensor, and an internal temperature sensor can also be provided on the vehicle. The external light intensity sensor is used to detect the light intensity outside the vehicle. The internal light intensity sensor is used to detect the light intensity inside the vehicle. The external temperature sensor is used to detect the temperature outside the vehicle. The internal temperature sensor is used to detect the temperature inside the vehicle.

[0047] In this embodiment, a camera device can also be provided inside the vehicle, and the camera device is used to collect images inside the vehicle. A millimeter-wave radar can also be provided inside the vehicle, and the millimeter-wave radar is used to collect information inside the vehicle.

[0048] The following combines Figure 1 to elaborate in detail on the method for adjusting the vehicle interior environment according to the embodiments of the present application.

[0049] Figure 2 shows a schematic flowchart of the method for adjusting the vehicle interior environment provided by the present application. Refer toFigure 2 , the details of this method are as follows:

[0050] S101, Obtain the external environment data of the vehicle.

[0051] In this embodiment, the vehicle can be a car, a truck, a bus, etc.

[0052] In this embodiment, the external environment data may include the external light intensity and / or the external temperature. The external light intensity can be obtained from an external light intensity sensor. The external temperature can be obtained from an external temperature sensor.

[0053] S102, When the external environment data meets the preset high temperature condition, obtain the vehicle state of the vehicle.

[0054] In this embodiment, the vehicle state may include a locked state and an unlocked state. The locked state is the state where the vehicle is locked and not in use. The unlocked state is the state where the user opens the vehicle and is about to use or is using the vehicle. The vehicle state can be determined by detecting the intelligent key system in the vehicle. Specifically, if the state of the intelligent key system is the key locked state, it is determined that the vehicle state is the locked state; if the state of the intelligent key system is the key start state, it is determined that the vehicle state is the unlocked state.

[0055] In this embodiment, generally, the stronger the light intensity, the higher the temperature, and the weaker the light intensity, the lower the temperature. Therefore, to determine whether the external environment of the vehicle is a high temperature environment, the light intensity and / or the external temperature can be used. The above-mentioned preset high temperature condition can include that the temperature is greater than the preset temperature, and / or the light intensity is greater than the preset intensity. The preset temperature and the preset intensity can both be set as needed.

[0056] S103, Based on the vehicle state, determine the control strategy for the electrochromic glass on the vehicle.

[0057] In this embodiment, after determining the vehicle state, a suitable control strategy can be selected according to the vehicle state. Specifically, when the vehicle is in the locked state, the vehicle is not in use, and any one or all of the electrochromic glasses can be selected to be powered on. However, when the vehicle is in the unlocked state, the vehicle may be being used or about to be used. If the front windshield, the rear windshield, and the front side window glass are set to gray, it will make the driver's vision worse and affect the driver's driving. Therefore, when the vehicle is in the unlocked state, the front windshield, the rear windshield, and the front side window glass cannot become gray. From the above, in different vehicle states, the electrochromic glasses that can be powered are different, and a suitable control strategy needs to be selected according to the vehicle state to avoid affecting the user's use.

[0058] S104, Based on the control strategy, control the battery device on the vehicle to supply power to the electrochromic glass.

[0059] In this embodiment, when using a battery device to supply power to an electrochromic glass, the solar component can be used to supply power to the electrochromic glass first. If the solar component includes a solar skylight, the solar skylight can be used to supply power to the electrochromic glass.

[0060] In this embodiment, before supplying power to the electrochromic glass based on a control strategy, it is also possible to detect whether the vehicle window corresponding to the electrochromic glass that needs to be powered is in a preset open state. If the window is not in the preset open state, power can be supplied to the electrochromic glass corresponding to the window; if the window is in the preset open state, power may not be supplied to the electrochromic glass, thereby reducing power consumption. The preset open state of the window can be set as needed. For example, the window is opened more than one-third, the window is opened more than one-half, etc.

[0061] As an example, if the control strategy includes supplying power to the front left window, first detect whether the front left window is in a preset open state. The preset open state can be that the opening degree of the window is greater than one-half. If the opening degree of the front left window is less than one-half, power can be supplied to the electrochromic glass on the front left window; otherwise, power is not supplied to the electrochromic glass on the front left window.

[0062] In the embodiment of the present application, first obtain the vehicle exterior environment data. If the vehicle exterior is a high-temperature environment, it is necessary to determine the vehicle state of the vehicle; determine the control strategy of the electrochromic glass according to the state of the vehicle, and finally supply power to the corresponding electrochromic glass according to the control strategy. The present application selects the control strategy of the electrochromic glass according to the vehicle exterior environment and vehicle state, and makes the electrochromic glass change from a transparent state to a grayscale state by supplying power to the electrochromic glass, so as to reduce the probability of external temperature passing through the glass into the vehicle, reduce the solar radiation, and make the interior environment of the vehicle more comfortable. In addition, the present application can use a solar component to supply power to the electrochromic glass, improving the utilization rate of the solar component on the vehicle.

[0063] As Figure 3 shown, in a possible implementation manner, the implementation process of step S103 may include:

[0064] S1031, when the vehicle state is a locked state, obtain the interior temperature of the vehicle.

[0065] In this embodiment, the interior temperature can be obtained from an interior temperature sensor.

[0066] S1032, when the interior temperature is greater than the exterior temperature, calculate the temperature difference between the interior temperature and the exterior temperature.

[0067] In this embodiment, if the temperature difference between the inside and outside of the vehicle is large, people will feel a strong sense of stuffiness after getting into the vehicle. Therefore, when the temperature difference between the inside and outside of the vehicle is large, it is necessary to control more electrochromic glass to change color to reduce the intake of sunlight, thereby achieving the effect of reducing the temperature inside the vehicle.

[0068] If the temperature difference between the inside and outside of the vehicle is small, people will not feel a strong sense of stuffiness after getting into the vehicle. Therefore, when the temperature difference between the inside and outside of the vehicle is small, it is possible to control less electrochromic glass to change color to achieve the effect of energy conservation and consumption reduction.

[0069] For the above reasons, when selecting a control strategy in the locked state of the vehicle, the corresponding control strategy can be selected according to the temperature difference between the inside and outside of the vehicle. Therefore, it is necessary to calculate the temperature difference between the inside and outside of the vehicle before determining the control strategy.

[0070] In this embodiment, if the temperature inside the vehicle is less than or equal to the temperature outside the vehicle, it is determined that the inside of the vehicle is in a comfortable state, and then the electrochromic glass does not need to be powered.

[0071] S1033. Determine the control strategy based on the temperature difference.

[0072] In this embodiment, a suitable control strategy can be selected according to the temperature difference.

[0073] Specifically, the implementation process of step S1033 may include:

[0074] S10331. When the temperature difference is greater than the first preset value, determine the first strategy as the control strategy.

[0075] In this embodiment, the first preset value can be selected as needed. For example, the first preset value can be 5 degrees, 8 degrees, 10 degrees, etc.

[0076] In this embodiment, the first strategy includes powering the electrochromic glass with the first number on the vehicle. The first number can be selected as needed. For example, if the total number of electrochromic glass on the vehicle is 6 pieces, the first number can be 6, 5, 4, etc.

[0077] Specifically, the position of the electrochromic glass with the first number can be selected arbitrarily.

[0078] As an example, if it is necessary to power 4 electrochromic glass on the vehicle, any 4 electrochromic glass on the vehicle can be selected to be powered.

[0079] In this embodiment, after determining that the first strategy is used as the control strategy, the battery device on the vehicle can also be controlled to supply power to the blower in the vehicle, and the blower and the electrochromic glass are used to cool the interior of the vehicle at the same time, so that the temperature inside the vehicle can reach a temperature close to the outside temperature faster.

[0080] S10331. When the temperature difference is less than the second preset value, determine that the second strategy is used as the control strategy.

[0081] In this embodiment, the second preset value can be set as needed. For example, the second preset value can be 2 degrees, 3 degrees, 4 degrees, etc.

[0082] In this embodiment, if the temperature difference is less than the second preset value, it can be determined that the temperature difference between the inside and outside of the vehicle is not large, and the battery module supplies power to the electrochromic glass less than the first number to achieve the effect of improving the interior environment. Therefore, the second strategy may include supplying power to the second number of electrochromic glass on the vehicle, and the second number is greater than 0 and less than the first number.

[0083] S10331. When the temperature difference is less than or equal to the first preset value and greater than or equal to the second preset value, continue to use the control strategy at the current time.

[0084] In this embodiment, when the temperature difference is between the first preset value and the second preset value, if the first strategy is used at the current time, the first strategy is used as the control strategy; if the second strategy is used at the current time, the second strategy is used as the control strategy.

[0085] As an example, if it is determined at the current time that the temperature difference is less than or equal to the first preset value and greater than or equal to the second preset value, and the temperature difference at the current time changes from greater than the first preset value to less than the first preset value, that is, the first strategy is used as the control strategy at the current time, the first strategy can continue to be used to supply power to the electrochromic glass.

[0086] If it is determined at the current time that the temperature difference is less than or equal to the first preset value and greater than or equal to the second preset value, and the temperature difference at the current time changes from less than the second preset value to greater than the second preset value, that is, the second strategy is used as the control strategy at the current time, the second strategy can continue to be used to supply power to the electrochromic glass.

[0087] In this embodiment, if no strategy is used as the control strategy at the current time, that is, no power is supplied to any electrochromic glass, it can continue to remain without supplying power to any electrochromic glass. After a period of time, the temperature difference between the inside and outside of the vehicle may become greater than the first preset value or less than the second preset value, and then the corresponding control strategy can be selected according to the temperature difference.

[0088] Optionally, after selecting the corresponding control strategy according to the temperature difference, the temperature range where the temperature difference is located can also be determined according to the temperature difference, the gray level of the electrochromic glass that needs to be powered can be determined according to the temperature range, and the supply current used when powering the electrochromic glass can be determined according to the gray level, so as to control the battery device to provide a corresponding current for the electrochromic glass.

[0089] As an example, if the temperature difference is 7, the first preset value is 5, the temperature difference is greater than the first preset value, and the temperature range where the temperature difference is located is the 1-2 range, and the gray level corresponding to the 1-2 range is level 1, then it is determined that the gray level of the electrochromic glass of the first number needs to be adjusted to level 1, and the supply current corresponding to the gray level of level 1 is A volts, and it is determined that the battery device needs to be controlled to provide a supply current of A volts for the electrochromic glass.

[0090] In a possible implementation manner, the implementation process of step S103 may include:

[0091] S1034, when the vehicle state is the non-locked state and the electrochromic glass on the vehicle includes the rear window glass, determine to use the third strategy as the control strategy.

[0092] In this embodiment, if the vehicle state is the non-locked state, it means that the user is about to or is using the vehicle. During the use of the vehicle, the glass on the rear window has no effect on the driver. Therefore, the third strategy may include powering the electrochromic glass on the rear window to achieve the effect of adjusting the interior environment of the vehicle. In addition, when the vehicle is in the non-locked state, changing the electrochromic glass on the rear window to gray can also block the sun for the rear seat passengers and prevent the sun from directly shining on the rear seat passengers.

[0093] As Figure 4 shown, in a possible implementation manner, when the control strategy is the third strategy, the implementation process of step S104 may include:

[0094] S1041, obtain the passenger state of the passengers on the rear row seats of the vehicle.

[0095] In this embodiment, the passenger state may include the sleep state and the awake state.

[0096] In this embodiment, the passenger state can be obtained by analyzing the video inside the vehicle collected by the camera device. Specifically, the video inside the vehicle collected by the camera device is obtained from the camera device, the image information of the rear seat passengers in the video is extracted, and the passenger state of the rear seat passengers is determined by analyzing the image information.

[0097] In this embodiment, the passenger state can also be obtained by analyzing the information collected by the millimeter wave radar.

[0098] S1042. When the passenger status is the sleep state, obtain the interior brightness of the vehicle.

[0099] In this embodiment, if the passenger is in the sleep state, the gray level of the electrochromic glass can be adjusted according to the interior brightness of the vehicle, so that the passenger has a comfortable sleeping environment.

[0100] In this embodiment, the interior brightness of the vehicle can be obtained from the interior light intensity sensor.

[0101] S1043. Based on the interior brightness of the vehicle, determine the gray level of the electrochromic glass on the rear side window.

[0102] In this embodiment, after obtaining the interior brightness of the vehicle, the brightness interval where the interior brightness is located can be determined. According to the gray level corresponding to the brightness interval where the interior brightness is located, the gray level of the electrochromic glass on the rear side window is obtained.

[0103] As an example, if the interior brightness is 5, the brightness interval where the interior brightness is located is 4 - 6, and the gray level corresponding to the brightness interval 4 - 6 is level 2, then it is determined that the gray level of the electrochromic glass on the rear side window needs to be adjusted to level 2.

[0104] S1044. Based on the gray level, control the battery device to supply power to the electrochromic glass on the rear side window.

[0105] In this embodiment, based on the gray level, the corresponding power supply current is determined, and based on the power supply current, the battery device is controlled to supply power to the electrochromic glass on the rear side window.

[0106] In this embodiment, if the passenger status is the awake state, the power supply to the electrochromic glass can be adjusted according to the preset standard gray level.

[0107] In this embodiment, the gray level of the electrochromic glass can also be determined according to the user instruction. The user instruction can be an instruction that the user acts on the central control screen, or a voice instruction input by the user.

[0108] In the embodiment of the present application, the gray level of the electrochromic glass on the rear side window can be determined through the interior brightness of the vehicle, and then power is supplied to it according to the gray level of the electrochromic glass on the rear side window, so that the gray level of the electrochromic glass can change with the interior brightness of the vehicle, providing a more comfortable environment for passengers.

[0109] In a possible implementation manner, the implementation process of step S104 may include:

[0110] S201. Control the solar component in the battery device to supply power to the electrochromic glass.

[0111] In this embodiment, after determining the control strategy, the solar component can be used to power the electrochromic glass according to the control strategy, which can improve the utilization rate of the solar component. At the same time, using the solar component to power the electrochromic glass can save energy.

[0112] S202. Detect the output electrical signal when the solar component powers the electrochromic glass.

[0113] In this embodiment, during the period when the solar component powers the electrochromic glass, the output electrical signal of the solar component can be detected, where the output electrical signal can be a current signal.

[0114] S203. When the output electrical signal is greater than the third preset value, control the solar cell component to charge the backup battery in the battery device and power the electrochromic glass.

[0115] In this embodiment, the third preset value can be set as needed. For example, the third preset value can be a current value. The third preset value can also be determined according to the gray level of the electrochromic glass determined above.

[0116] In this embodiment, if the output electrical signal is greater than the third preset value, it indicates that the output electrical signal of the solar component can not only meet the power consumption requirements of the electrochromic glass, but there is also an excess electrical signal in the solar component. Transmit the excess electrical signal in the solar component to the backup battery for storage for subsequent use.

[0117] S204. When the output electrical signal is less than or equal to the third preset value, control the backup battery and the solar component to power the electrochromic glass.

[0118] In this embodiment, if the output electrical signal of the solar component is less than or equal to the third preset value, it is determined that the output electrical signal in the solar component cannot meet the usage requirements of the electrochromic glass, and the backup battery and the solar component need to power the electrochromic glass simultaneously so that the electrochromic glass can reach the preset gray level.

[0119] As Figure 5 shown, in a possible implementation, when the vehicle state is the non-locking state, if the air conditioner in the vehicle is in the on state, the air conditioner can also be controlled.

[0120] Specifically, the above method may further include:

[0121] S301. Obtain the parameter value of the refrigerant at the outlet end of the condenser in the vehicle.

[0122] In this embodiment, the parameter value includes a pressure value and a temperature value.

[0123] S302. Calculate the degree of undercooling of the refrigerant based on the parameter value.

[0124] In this embodiment, the degree of supercooling refers to the difference between the temperature of condensed water under a certain pressure and the saturation temperature under the corresponding pressure, or the difference between the theoretical crystallization temperature of a substance (such as metal, alloy, crystal) and the actual given crystallization site temperature. The degree of supercooling can also be calculated based on the pressure value and temperature value of the liquid.

[0125] S303. When the degree of supercooling is less than the fourth preset value and the subcooler connected in series with the condenser is in a non-operating state, control the battery device to supply power to the subcooler, so that the subcooler switches to the operating state and cools down the refrigerant when in the operating state.

[0126] In this embodiment, the subcooler is in the operating state when it is powered on and opened, and in the non-operating state when it is powered off and turned off.
