[0102] The technical solution of the present disclosure is further described in detail below through examples and in conjunction with the accompanying drawings. In the specification, the same or similar reference numerals indicate the same or similar components. The following description of the embodiments of the present disclosure with reference to the accompanying drawings is intended to explain the overall inventive concept of the present disclosure and should not be construed as limiting the present disclosure.

[0103] Furthermore, in the following detailed description, for ease of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the present disclosure. However, it will be apparent that one or more embodiments can be practiced without these specific details.

[0104] It should be understood that, although the terms first, second, etc. can be used here to describe different elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. For example, without departing from the scope of the exemplary embodiments, the first element can be named as the second element, and similarly, the second element can be named as the first element. As used herein, the term "and / or" includes any combination and all combinations of one or more related listed items.

[0105] The terms used herein are for the purpose of describing specific embodiments only and are not intended to limit the exemplary embodiments. As used herein, unless the context clearly indicates otherwise, the singular is intended to include the plural. It will also be understood that when the terms "comprise" and / or "include" are used herein, they indicate the presence of the described features, integers, steps, operations, elements and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or combinations thereof.

[0106] In this document, unless otherwise specified, the term "vehicle" includes any movable means of transport, including but not limited to two-wheeled motor vehicles, three-wheeled motor vehicles, four-wheeled motor vehicles, trains, etc.

[0107] The expression "light intensity", also known as light intensity, refers to the luminous flux of visible light received per unit area. Its unit is lux (lux or lx), which is used to indicate the intensity of light and the degree of illumination of the surface area of ​​an object.

[0108] The inventors have discovered that with the advancement of intelligent, electrified, and connected vehicles, smart cockpit technology has become an integral part of vehicles. A key component of the smart cockpit is automotive glass, including front and rear windshields, sunroofs, side windows, and sun visors. With technological advancements and increasing user demands, automotive glass is required to possess an increasing number of functions. For example, in addition to its conventional light-transmitting function, it must also display images and interact with the user. Automotive glass with display and interactive functions requires the comprehensive use of technologies such as thin-film transistor arrays, display control, and multi-color pixels. Consequently, the cost of such glass is higher than that of traditional automotive glass. To meet user needs while balancing costs, a currently promising technology direction is dimming glass. In other words, when dimming glass is used in vehicles, it not only performs its conventional light-transmitting function but also enables functions such as displaying images and interacting with the user.

[0109] Technologies used in switchable glass may include PDLC (polymer dispersed liquid crystal), EC (electrochromic) and SPD (suspended particle) technologies.

[0110] PDLC switchable glass entered mass production relatively early, offering relatively low cost and capable of achieving both transparent and atomized effects. When powered on, the polymer-dispersed liquid crystal molecules align in an orderly fashion, allowing light to pass directly through the glass. When powered off, the polymer-dispersed liquid crystal molecules become disordered, scattering light and creating a hazy effect. PDLC switchable glass is typically whitish in color, and when atomized, it creates a soft, natural-looking glow.

[0111] The suspended particles in SPD dimming glass absorb over 99% of visible light. When powered off, the glass appears foggy; when powered on, the suspended particles align (order) to allow light to pass through. SPD dimming glass achieves continuously adjustable light levels. However, due to the characteristics of the suspended particles, SPD dimming glass requires a 110V voltage and enhanced safety measures, which directly increases costs. SPD dimming glass is typically blue, giving it a different appearance from PDLC glass.

[0112] EC dimming glass uses color changes caused by materials and electric fields to adjust the glass's light transmittance. EC dimming glass consists of three components: an ion storage layer, a solid-state electrolyte, and an electrochromic layer. It features low voltage, low haze, and power-off memory. Under the influence of an electric field, the reflectivity, transmittance, and absorptivity of the electrochromic layer change, thereby altering the light passing through the glass. EC dimming glass primarily comes in gray and blue.

[0113] In an embodiment of the present disclosure, the switchable glass may include dye liquid crystal switchable glass.

[0114] 1 is a schematic plan view of a switchable glass according to some exemplary embodiments of the present disclosure, and FIG. 2 is a cross-sectional view of the switchable glass according to some exemplary embodiments of the present disclosure taken along line AA′ in FIG. 1 .

[0115] 1 and 2 , the dimming glass 10 may include a first dimming substrate 1 and a second dimming substrate 2 that are oppositely disposed, and a dimming component 3 that is sandwiched between the first dimming substrate 1 and the second dimming substrate 2 .

[0116] The first dimming substrate 1 may include a first base substrate 11 , a first electrode 12 , a first insulating layer 13 , and a first alignment layer 14 . The first electrode 12 , the first insulating layer 13 , and the first alignment layer 14 are sequentially disposed on the first base substrate 11 .

[0117] The second dimming substrate 2 may include a second base substrate 21, a second electrode 22, and a second alignment layer 24. The second electrode 22 and the second alignment layer 24 are sequentially disposed on the second base substrate 21.

[0118] The switchable glass 10 may further include spacers 32 for supporting the glass. Optionally, the spacers 32 may be spherical, columnar, or other shaped spacers. The spacers 32 may be made of transparent or non-transparent materials.

[0119] For example, the first base substrate 11 and the second base substrate 21 can be transparent glass substrates. For example, the switchable glass 10 can be applied to fields such as architecture, transportation, and interior decoration design to achieve switching between a transparent state and a non-transparent state (e.g., a dark state or a foggy state), and continuously change the transparency of the glass.

[0120] For example, the first electrode 12 and the second electrode 22 may be transparent electrodes, respectively. For example, they may be made of a transparent conductive material such as indium tin oxide (ITO).

[0121] In some embodiments of the present disclosure, the dimming component 3 may include a liquid crystal layer. For example, the liquid crystal layer may include dye liquid crystals. Specifically, the liquid crystal layer may include liquid crystal molecules and chromatic dye molecules mixed with the liquid crystal molecules. For example, the chromatic dye molecules may be dichroic dye molecules.

[0122] The first electrode 12 included in the first dimming substrate 1 includes a plurality of first sub-electrodes 121, which are arranged at intervals on the first base substrate 11. That is, the orthographic projection of the first electrode 12 on the first base substrate 11 forms a plurality of spaced-apart strips. It should be understood that each first sub-electrode 121 is transparent, for example, each first sub-electrode 121 is formed of a transparent conductive material such as ITO.

[0123] 1 and 2 , the switchable glass 10 may further include a plurality of traces 15 disposed on the first base substrate 11. For example, the plurality of traces may correspond one-to-one to the plurality of first sub-electrodes 121. For example, each trace may be a conductive trace made of a conductive material.

[0124] 1 and 2 , the switchable glass 10 may further include a drive circuit 16, such as an integrated circuit (IC), configured to provide electrical signals. Specifically, a plurality of traces may electrically connect corresponding first sub-electrodes 121 to the drive circuit 16, such as an IC. In this manner, the control signals provided by the drive circuit 16 may be supplied to each of the first sub-electrodes 121.

[0125] The second electrode 22 included in the second dimming substrate 2 can be a planar electrode, that is, the orthographic projection of the second electrode 22 on the second base substrate 21 forms a continuously distributed planar graphic shape. For example, in the embodiment of Figure 1, the orthographic projection of the second electrode 22 on the second base substrate 21 forms a complete rectangle.

[0126] Exemplarily, as shown in FIG. 1 , the orthographic projection of the first electrode 12 on the first base substrate 11 falls within the orthographic projection of the second electrode 22 on the first base substrate 11 .

[0127] It should be understood that the second electrode 22 may also be electrically connected to the driving circuit 16 , such as an IC, through a conductive structure (such as a trace), so that the control signal provided by the driving circuit 16 may be supplied to the second electrode 22 .

[0128] In the switchable glass provided by the embodiments of the present disclosure, when no voltage is applied to the first electrode 12 and the second electrode 22, no electric field is generated between the first electrode 12 and the second electrode 22. The liquid crystal molecules and the chromatic dye molecules in the dimming component 3 are vertically oriented and do not absorb light, causing the switchable glass to be in a light-transmitting state (i.e., a completely transparent state). When a predetermined voltage is applied to the first electrode 12 and the second electrode 22, an electric field is generated between the first electrode 12 and the second electrode 22, causing the liquid crystal molecules and the chromatic dye molecules in the liquid crystal layer 3 to be deflected. The liquid crystal molecules align horizontally under the action of the electric field, inducing the chromatic dye molecules to align horizontally, which absorbs light, causing the switchable glass to be in an opaque state (i.e., a completely dark state), or to exhibit a transparency between the completely dark state and the completely transparent state.

[0129] In this embodiment, the dimming glass provided by the embodiment of the present disclosure is described using dye liquid crystal as an example. It should be understood that the dimming glass provided by the embodiment of the present disclosure is not limited to dye liquid crystal dimming glass, but may also include other types of dimming glass, including but not limited to PDLC dimming glass, SPD dimming glass, EC dimming glass, etc.

[0130] The inventors have found that cars usually have at least three driving modes: sport mode, normal mode and energy-saving mode. Sport mode (Sport): a more aggressive driving style, better power, and faster speed. The sport mode allows the vehicle to instantly burst out greater power by increasing the engine speed or quickly downshifting. Normal mode (Normal): also known as comfort mode or leisure mode. The normal mode is to ensure that the power remains unchanged and to obtain better fuel economy. Using the control in normal mode, the car's throttle response is the most balanced, and the handling feel is simpler, more comfortable, and easier to use. Energy-saving mode (ECO): also known as economic mode, a more economical and fuel-efficient driving style, suitable for daily commuting. The energy-saving mode controls the engine speed with a reasonable gear position, reduces unnecessary fuel consumption, and pursues economical fuel consumption.

[0131] In an embodiment of the present disclosure, dimming glass technology is applied to a vehicle. Specifically, at least one of the vehicle's front and rear windshields, sunroof, side windows, and sun visor can be the aforementioned dimming glass. Based on this, by adjusting the light transmittance of the dimming glass, it is possible to provide safety and protect privacy. For example, when the vehicle is turning, changing lanes, or driving at high speed, the light transmittance of the dimming glass can be increased, allowing the driver to observe the external environment more clearly, thereby improving driving safety. When someone is resting in the vehicle or there are other vehicles nearby, the light transmittance of the dimming glass can be reduced, thereby improving the privacy protection of the occupants.

[0132] On the one hand, improving safety requires increasing the light transmittance of dimming glass, while on the other hand, protecting privacy requires reducing it. These two requirements for dimming glass are contradictory. How to intelligently adjust the dimming glass to balance the needs of improving safety and protecting privacy is one of the challenges that need to be addressed in automotive dimming glass applications.

[0133] Embodiments of the present disclosure provide a control method and system for a vehicle's dimming glass system. The control method includes: obtaining a vehicle driving mode selected by a user from m preset vehicle driving modes, where m is a positive integer greater than or equal to 2; determining a dimming mode corresponding to the user-selected vehicle driving mode based on a mapping relationship between vehicle driving modes and dimming modes, where the mapping relationship includes a mapping relationship between the m preset vehicle driving modes and n dimming modes; and controlling the vehicle's dimming glass system based on the dimming mode.

[0134] In the embodiments of the present disclosure, the dimming modes of the dimming glass are set differently according to different vehicle driving modes, which can take into account the needs of improving safety and protecting privacy, thereby providing users with a better driving experience.

[0135] It should be noted that, in this document, unless otherwise specified, "transmittance adjustment information" includes adjusting at least one of the magnitude and the change rate of light transmittance.

[0136] It should be noted that, in this article, unless otherwise specified, "controlling the dimming glass system of the vehicle" includes: controlling the light transmittance of the dimming glass, selecting and controlling the glass to be dimmed, and controlling the partitioning of the dimming glass.

[0137] The embodiments of the present disclosure are described in further detail below with reference to the accompanying drawings.

[0138] In some embodiments of the present disclosure, a dimming glass system for a vehicle is provided. FIG3 is a schematic structural diagram of a dimming glass system for a vehicle according to an exemplary embodiment of the present disclosure. With reference to FIG1 to FIG3 , the dimming glass system 100 includes a dimming glass 10 and a controller 4. The dimming glass can be implemented based on one or more embodiments as shown in FIG1 to FIG2 above and installed on a vehicle; and the controller 4 is electrically connected to the first electrode 12 and the second electrode 22 of the dimming glass 10. For example, the controller 4 can also be connected to the vehicle's on-board system 5. The controller 4 can be connected to the vehicle's on-board system 5 via a LIN or CAN bus.

[0139] For example, in the embodiment shown in FIG3 , a light intensity sensor 61 , a vehicle speed sensor 62 , a radar sensor 63 and a seat controller 64 connected to the vehicle system 5 , and a seat 65 connected to the seat controller 64 are schematically shown.

[0140] Hereinafter, the working process of the controller 4 will be further described in conjunction with a specific control method.

[0141] 4 is a flow chart of a control method of a switchable glass system according to some exemplary embodiments of the present disclosure, wherein the control method includes steps S410 to S460.

[0142] In step S410, a vehicle driving mode selected by a user from m preset vehicle driving modes is obtained, where m is a positive integer greater than or equal to 2.

[0143] In step S420, the dimming mode corresponding to the vehicle driving mode selected by the user is determined based on the mapping relationship between the vehicle driving mode and the dimming mode, wherein the mapping relationship between the vehicle driving mode and the dimming mode includes a mapping relationship between preset m vehicle driving modes and n dimming modes, wherein n is a positive integer greater than or equal to 2.

[0144] In some embodiments, m can be equal to n, i.e., the number of vehicle driving modes and dimming modes is the same, and the m vehicle driving modes and n dimming modes can correspond one to one. In this embodiment, a corresponding dimming mode can be determined for each vehicle driving mode, which facilitates tailoring the dimming mode for each vehicle driving mode and achieving personalized customization of the dimming mode under each vehicle driving mode.

[0145] In some embodiments, m can be greater than n, that is, the number of vehicle driving modes is greater than the number of dimming modes. For example, a vehicle may include three driving modes: sport mode, normal mode, and energy-saving mode. The vehicle may also include two dimming modes. For example, the sport mode corresponds to one dimming mode, while the normal mode and energy-saving mode may share one dimming mode. In this embodiment, some vehicle driving modes can share one dimming mode, which can reduce the number of dimming modes and facilitate user operation.

[0146] In some embodiments, m can be less than n, that is, the number of vehicle driving modes is less than the number of dimming modes. For example, a vehicle may include three driving modes: sport mode, normal mode, and energy-saving mode. The vehicle may also include four dimming modes. For example, the sport mode corresponds to two dimming modes, and the normal mode and energy-saving mode each correspond to one dimming mode. In this embodiment, some vehicle driving modes may correspond to more than two dimming modes, enabling more precise control of the dimming modes in some vehicle driving modes, which helps meet the diverse needs of users.

[0147] In step S430, the dimming glass system of the vehicle is controlled according to the dimming mode.

[0148] In some exemplary embodiments of the present disclosure, the n dimming modes each have a fixed light transmittance or light transmittance range. In other words, the n dimming modes each correspond to a fixed light transmittance or light transmittance range. When a user selects a vehicle driving mode, a dimming mode is mapped to the vehicle driving mode, and the corresponding fixed light transmittance or light transmittance range is determined by the dimming mode.

[0149] In this embodiment, in step S430, controlling the dimming glass system of the vehicle according to the dimming mode includes controlling the dimming glass system of the vehicle according to a fixed light transmittance or a light transmittance range of the dimming mode.

[0150] In some exemplary embodiments, the m vehicle driving modes include a first vehicle driving mode. For example, the first vehicle driving mode may be a sports mode. In this embodiment, the n dimming modes include a first dimming mode, and the mapping relationship between the vehicle driving modes and the dimming modes includes a mapping relationship between the first vehicle driving mode and the first dimming mode.

[0151] In some exemplary embodiments, the m vehicle driving modes further include a second driving mode. For example, the second driving mode may be a normal mode. In this embodiment, the n dimming modes further include a second dimming mode, and the mapping relationship between the vehicle driving modes and the dimming modes further includes a mapping relationship between the second vehicle driving mode and the second dimming mode.

[0152] In some exemplary embodiments, the light transmittance or light transmittance range in the first dimming mode is higher than the light transmittance or light transmittance range in the second dimming mode. This design allows the light transmittance in sports mode to be higher than that in normal mode, thereby achieving a balance between safety in sports mode and privacy protection in normal mode.

[0153] In some exemplary embodiments, the m vehicle driving modes further include a third driving mode. For example, the third driving mode may be an energy-saving mode. In this embodiment, the n dimming modes further include a third dimming mode, and the mapping relationship between the vehicle driving modes and the dimming modes further includes a mapping relationship between the third vehicle driving mode and the third dimming mode.

[0154] In some exemplary embodiments, the light transmittance or the light transmittance range in the third dimming mode is between the light transmittance or the light transmittance range in the first dimming mode and the light transmittance or the light transmittance range in the second dimming mode.

[0155] In step S440 , at least one of a safety-related event and a privacy-related event of the vehicle is detected.

[0156] In step S450 , transmittance adjustment information of the dimming glass on the vehicle is determined according to the dimming mode selected by the user and the at least one detected event.

[0157] In step S460 , the light transmittance of the switchable glass is adjusted according to the transmittance adjustment information.

[0158] In an embodiment of the present disclosure, in at least two dimming modes among the n dimming modes, priorities of security-related events and privacy-related events are different.

[0159] In some exemplary embodiments, the m vehicle driving modes include a first vehicle driving mode. For example, the first vehicle driving mode may be a sports mode. In this embodiment, the n dimming modes include a first dimming mode, and the mapping relationship between vehicle driving modes and dimming modes includes a mapping relationship between the first vehicle driving mode and the first dimming mode. In the first dimming mode, all security-related events have a higher priority than privacy-related events.

[0160] In some exemplary embodiments, the m vehicle driving modes further include a second driving mode. For example, the second driving mode may be a normal mode. In this embodiment, the n dimming modes further include a second dimming mode, and the mapping relationship between vehicle driving modes and dimming modes further includes a mapping relationship between the second vehicle driving mode and the second dimming mode. In the second dimming mode, at least some privacy-related events have a higher priority than at least some security-related events.

[0161] In some exemplary embodiments, the m vehicle driving modes include a third vehicle driving mode. For example, the third vehicle driving mode may be an energy-saving mode. In this embodiment, the n dimming modes include a third dimming mode, and the mapping relationship between vehicle driving modes and dimming modes includes a mapping relationship between the third vehicle driving mode and the third dimming mode. In the third dimming mode, the priority of all security-related events is higher than the priority of privacy-related events, or the priority of security-related events and privacy-related events may be at the same level.

[0162] Table 1 exemplifies the priorities and considerations in different vehicle driving modes. With reference to Table 1 and Figure 4, exemplarily, the first vehicle driving mode may be a sports mode, the second vehicle driving mode may be a normal mode, and the third vehicle driving mode may be an energy-saving mode. The safety-related events include at least one of the following events: vehicle turning, vehicle changing lanes, and vehicle speed exceeding a speed threshold. The privacy-related events include at least one of the following events: passengers in the vehicle are in a resting state, and there are other vehicles near the vehicle. For example, the other vehicles near the vehicle may include at least one of the following situations: for a driving vehicle, there are other vehicles driving side by side in an adjacent lane of the vehicle; for a vehicle parked in a parking space, there are other vehicles parked side by side in an adjacent parking space of the vehicle.

[0163] In the first driving mode (i.e., Sport mode), due to the relatively aggressive driving style, safety is prioritized. As shown in Table 1, safety-related events have a higher priority than privacy-related events. In the second driving mode (i.e., Normal mode), users pursue a relatively comfortable driving experience, so the priority of some privacy-related events is increased. As shown in Table 1, some safety-related events have a lower priority than privacy-related events.

[0164] Table 1

[0165] In this embodiment, by setting different priorities for security or privacy-related events according to different vehicle driving modes, user needs for improving security and protecting privacy can be taken into account, thereby providing users with a better driving experience.

[0166] 5 is a flow chart of a control method of a switchable glass system according to some exemplary embodiments of the present disclosure, wherein the control method includes steps S510 to S540.

[0167] In step S510 , the user may select a vehicle driving mode.

[0168] Specifically, the vehicle's onboard system provides a user selection interface, allowing users to set different dimming modes for different vehicle driving modes. The onboard system then establishes a mapping relationship between the vehicle driving mode and the dimming mode. For example, the initial light transmittance of the dimming glass can be set to different values ​​in different dimming modes. Specifically, the initial light transmittance of the dimming glass in different dimming modes can be set by sliding the dimming glass control bar or rotating the dimming glass knob.

[0169] In step S520, when the user selects the sports mode, the dimming glass is set to the first dimming mode. For example, in the first dimming mode, the initial light transmittance of the dimming glass is high to provide a better field of view.

[0170] In step S530, when the user selects the normal mode, the dimming glass is set to the second dimming mode. For example, in the second dimming mode, the initial light transmittance of the dimming glass is lower, for example, lower than the initial light transmittance of the dimming glass in the first dimming mode, to provide better privacy protection.

[0171] In step S540, when the user selects the energy-saving mode, the dimming glass is set to the third dimming mode. For example, in the third dimming mode, the initial light transmittance of the dimming glass is moderate, for example, the initial light transmittance in the third dimming mode is between the initial light transmittance in the first dimming mode and the initial light transmittance in the second dimming mode.

[0172] Based on this, in some exemplary embodiments of the present disclosure, the control method may further include: determining an initial light transmittance of the switchable glass based on the determined dimming mode. For example, the initial light transmittance in the first dimming mode is higher than the initial light transmittance in the second dimming mode. The initial light transmittance in the third dimming mode is between the initial light transmittance in the first dimming mode and the initial light transmittance in the second dimming mode.

[0173] 6 is a flow chart of a control method of a switchable glass system in a motion mode according to some exemplary embodiments of the present disclosure. In the motion mode, the control method includes steps S610 to S650.

[0174] 6 , in step S610 , the vehicle driving mode selected by the user is obtained as the first vehicle driving mode, ie, the sports mode.

[0175] In the sports mode, the priority of all security-related events is higher than the priority of privacy-related events. In this embodiment, the security-related events are detected and judged first.

[0176] In step S620, all safety-related events are judged according to the determined first dimming mode.

[0177] In step S630, in response to at least one security-related event satisfying a security protection trigger condition, the light transmittance of at least one switchable glass is increased.

[0178] Then, after judging all security-related events, privacy-related events can be detected and judged.

[0179] In step S640 , in response to all security-related events failing to meet the security triggering condition, a privacy-related event is judged.

[0180] In step S650, in response to at least one privacy-related event satisfying a privacy protection trigger condition, the light transmittance of at least one switchable glass is reduced.

[0181] 7 is an exemplary flow chart of a control method of a switchable glass system in a motion mode according to some exemplary embodiments of the present disclosure. In the motion mode, the control method includes steps S710 to S790.

[0182] 7 , in step S710 , the vehicle driving mode selected by the user is obtained as the first vehicle driving mode, ie, the sports mode.

[0183] In the sports mode, the priority of all security-related events is higher than the priority of privacy-related events. In this embodiment, the security-related events are detected and judged first.

[0184] In step S730, a first safety-related event is determined based on the determined first dimming mode. For example, the first safety-related event may be a vehicle turning, that is, in this step, it is determined whether the vehicle is turning.

[0185] In step S740, in response to the first safety-related event satisfying the safety protection trigger condition, the light transmittance of at least one dimming glass is increased. For example, in response to the vehicle turning, the light transmittance of the dimming glass located on the front side window of the vehicle is increased. This can improve driving safety when turning.

[0186] In step S760, in response to the first safety-related event not meeting the safety protection trigger condition, a second safety-related event is determined. For example, the second safety-related event may be the vehicle speed exceeding a speed threshold. In this step, in response to the vehicle not turning, a determination is made as to whether the vehicle speed exceeds a preset speed threshold.

[0187] In step S770, in response to the second safety-related event satisfying the safety protection trigger condition, the light transmittance of at least one dimming glass is increased. For example, in response to the vehicle speed exceeding a speed threshold, i.e., the vehicle is traveling at high speed, the light transmittance of the dimming glass located on the front side windows of the vehicle is increased, and the light transmittance of the dimming glass located on the side windows near the passenger side is increased. This can improve driving safety during high-speed driving.

[0188] In step S780, in response to the second security-related event not meeting the security protection triggering condition, at least one privacy-related event is determined. For example, in response to the vehicle speed not exceeding the vehicle speed threshold, it can be determined whether there are other vehicles near the vehicle.

[0189] In step S790, in response to at least one privacy-related event satisfying a privacy protection trigger condition, the light transmittance of at least one dimming glass is reduced. For example, in response to the presence of other vehicles near the vehicle, the light transmittance of at least one dimming glass may be reduced, such as the light transmittance of the dimming glass located on the front side windows of the vehicle and the light transmittance of the dimming glass located on the side windows near the passenger side. This protects the privacy of the vehicle occupants.

[0190] In an embodiment of the present disclosure, in sports mode, due to the relatively aggressive driving style, priority is given to safety-related events. While ensuring driving safety, privacy protection is also taken into account, thereby achieving the effects of improving safety and protecting privacy.

[0191] 7 , optionally, in some exemplary embodiments of the present disclosure, in step S720, the initial light transmittance of the switchable glass may be determined based on the first dimming mode and the environment the vehicle is in. For example, the initial light transmittance of the switchable glass may be determined based on the first dimming mode and environmental factors such as weather, light intensity, and time.

[0192] Continuing with FIG. 7 , optionally, in some exemplary embodiments of the present disclosure, the control method may further include steps S7201 and S7202. In step S7201, the vehicle's environment may be continuously detected for changes, for example, changes in environmental factors such as weather, light intensity, and time of day. In step S7202, the initial light transmittance of the switchable glass may be adjusted in response to changes in the vehicle's environment.

[0193] Continuing to refer to FIG. 7 , optionally, in some exemplary embodiments of the present disclosure, in step S750 , the method further includes: obtaining the distribution positions of the people in the vehicle.

[0194] In step S770 and step S790, the dimming glass that needs to adjust the light transmittance can be determined according to the distribution positions of the people in the vehicle.

[0195] For example, in response to the first safety-related event satisfying the safety protection trigger condition, increasing the light transmittance of at least one dimming glass includes: in response to the first safety-related event satisfying the safety protection trigger condition, increasing the light transmittance of the dimming glass located at the side window of the front row of the vehicle.

[0196] For example, in response to the second safety-related event satisfying the safety protection trigger condition, increasing the light transmittance of at least one dimming glass includes: in response to the second safety-related event satisfying the safety protection trigger condition, increasing the light transmittance of the dimming glass of the side window located on the driver's side of the vehicle and the side window located near the passenger in the vehicle.

[0197] For example, reducing the light transmittance of at least one switchable glass includes reducing the light transmittance of the switchable glass of a side window located on the driver's side of the vehicle and a side window located near a passenger in the vehicle.

[0198] In some embodiments of the present disclosure, the light transmittance of the dimming glass near the position of the occupants in the vehicle can be adjusted based on the distribution of the occupants in the vehicle. For example, when there is a passenger in the left rear seat of the vehicle, the glass of the left rear window can be determined as the glass requiring light transmittance adjustment; when there is a passenger in the right rear seat of the vehicle, the glass of the right rear window can be determined as the glass requiring light transmittance adjustment; when there is a passenger in the middle rear seat of the vehicle, the glass of the two rear windows can be determined as the glass requiring light transmittance adjustment.

[0199] In some embodiments of the present disclosure, when adjusting the light transmittance according to the distribution positions of the people in the vehicle, it is also necessary to consider environmental factors such as weather and light intensity. For example, in a mode for the purpose of sunshade, "determining the light transmittance according to the distribution position" can include adjusting the light transmittance so that the glass near the people in the vehicle is at a low transmittance, thereby reducing the exposure of the people in the vehicle to external light. In a mode for partial protection of safe driving, for example, in order to avoid strong external light irritating the driver's eyes, the light transmittance of the driver's side window glass can be reduced. In a mode for the purpose of facilitating the observation of the external environment by the people in the vehicle, for example, it can be convenient for the driver to observe the surrounding vehicles when driving out of a dim basement, and it can be convenient for the rear passengers to sightsee the scenery during the journey. At this time, the light transmittance of the glass near the people in the vehicle can be increased.

[0200] Figures 8A to 8G schematically illustrate the correspondence between occupant distribution within a vehicle and glass dimming control. In Figures 8A to 8G, a seat with a 45° line indicates that a person is present at that location, and a side window with a 45° line indicates that the window requires dimming control.

[0201] For example, referring to Figure 8A , when there is only a driver in the vehicle with no other passengers, and the vehicle speed exceeds a speed threshold, the light transmittance of the dimming glass on the front driver's side window may be increased only. Referring to Figure 8B , when there is only a driver in the vehicle with no other passengers, and the vehicle speed exceeds a speed threshold, the light transmittance of the dimming glass on both front side windows may be increased. Referring to Figure 8C , when there is a driver and a passenger in the front passenger seat, and the vehicle speed exceeds a speed threshold, the light transmittance of the dimming glass on both front side windows may be increased. Referring to Figure 8D , when there are passengers in the driver's seat and the left rear seat, and the vehicle speed exceeds a speed threshold, the light transmittance of the dimming glass on both front side windows and the left rear window may be increased. Referring to Figure 8E , when there are passengers in the driver's seat and the left rear seat, and when other vehicles are nearby, the light transmittance of the dimming glass on both front side windows and the left rear window may be reduced to protect privacy. Referring to Figure 8F , when there is someone between the driver's seat and the rear seat, or when there are other vehicles nearby, the light transmittance of the dimming glass on both sides of the front and rear windows can be reduced to protect privacy. Referring to Figure 8G , when there is someone between the driver's seat and the right rear seat, or when there are other vehicles nearby, the light transmittance of the dimming glass on both sides of the front and rear windows can be reduced to protect privacy.

[0202] Optionally, in some exemplary embodiments, the control method may further include: controlling the passenger seat to move rearward in response to the vehicle turning toward the passenger seat. For example, in step S730, it is determined whether the vehicle is turning right; in step S740, in response to the vehicle turning right, the light transmittance of the dimming glass on both sides of the front windows may be increased, and the passenger seat may be controlled to move rearward to avoid obstructing the driver's vision.

[0203] 9 is a flow chart of a control method of a switchable glass system in a normal mode according to some exemplary embodiments of the present disclosure. In the normal mode, the control method includes steps S910 to S940.

[0204] 9 , in step S910 , the vehicle driving mode selected by the user is obtained as the second vehicle driving mode, ie, the normal mode.

[0205] In normal mode, some security-related events have a lower priority than privacy-related events.

[0206] In step S920, at least one privacy-related event is judged according to the determined second dimming mode.

[0207] In step S930, in response to at least one privacy-related event satisfying a privacy protection trigger condition, at least one security-related event is judged.

[0208] In step S940, in response to at least one security-related event not satisfying a security protection triggering condition, the light transmittance of at least one switchable glass is reduced.

[0209] 10 is an exemplary flow chart of a control method of a switchable glass system in a normal mode according to some exemplary embodiments of the present disclosure. In the normal mode, the control method includes steps S1010 to S1090.

[0210] 10 , in step S1010 , the vehicle driving mode selected by the user is obtained as the second vehicle driving mode, ie, the normal mode.

[0211] In normal mode, some security-related events have a lower priority than privacy-related events.

[0212] In step S1030, a first safety-related event is determined based on the determined second dimming mode. For example, the first safety-related event may be a vehicle turning, that is, in this step, it is determined whether the vehicle is turning.

[0213] In step S1040, in response to the first safety-related event satisfying the safety protection trigger condition, the light transmittance of at least one smart glass is increased. For example, in response to the vehicle turning, the light transmittance of the smart glass located on the front side window of the vehicle is increased. This can improve driving safety when turning.

[0214] In step S1060, in response to the first security-related event not meeting the security protection trigger condition, at least one privacy-related event is determined. For example, the at least one privacy-related event may include whether there are other vehicles near the vehicle. In this step, in response to the vehicle not turning, a determination is made as to whether there are other vehicles near the vehicle.

[0215] In step S1070, in response to at least one privacy-related event not meeting the privacy protection triggering condition, the light transmittance of at least one dimming glass is increased. For example, in response to the absence of other vehicles near the vehicle, the light transmittance of the dimming glass located on the front side window of the vehicle may be increased, as may the light transmittance of the dimming glass located on the side window near the passenger seat. This can improve driving safety.

[0216] In step S1080, in response to at least one privacy-related event satisfying the privacy protection trigger condition, a second security-related event is determined. For example, in response to the presence of other vehicles near the vehicle, a determination is made as to whether the vehicle's speed exceeds a speed threshold.

[0217] In step S1070, in response to the second safety-related event satisfying the safety protection trigger condition, the light transmittance of at least one dimming glass is increased. For example, in response to the vehicle speed exceeding a speed threshold, i.e., the vehicle is traveling at high speed, the light transmittance of the dimming glass located on the front side windows of the vehicle is increased, and the light transmittance of the dimming glass located on the side windows near the passenger side is increased. This can improve driving safety during high-speed driving.

[0218] In step S1090, in response to the second safety-related event not meeting the safety protection triggering condition, the light transmittance of at least one dimming glass is reduced. For example, in response to the vehicle not being driven at high speed, the light transmittance of the dimming glass located on the front side windows of the vehicle is reduced, as is the light transmittance of the dimming glass located on the side windows near the passenger side. This protects the privacy of the vehicle occupants.

[0219] In the embodiment of the present disclosure, in normal mode, since the driving style is relatively comfortable, it is possible to consider increasing the priority of some privacy-related events while ensuring safety. While ensuring driving safety, privacy protection is prioritized, thereby achieving the effect of balancing improved safety and privacy protection.

[0220] Continuing with FIG. 10 , optionally, in some exemplary embodiments of the present disclosure, in step S1020, the initial light transmittance of the switchable glass may be determined based on the second dimming mode and the environment the vehicle is in. For example, the initial light transmittance of the switchable glass may be determined based on the second dimming mode and environmental factors such as weather, light intensity, and time.

[0221] Continuing with FIG. 10 , optionally, in some exemplary embodiments of the present disclosure, the control method may further include steps S10201 and S10202. In step S10201, the vehicle's environment may be continuously detected for changes, for example, changes in environmental factors such as weather, light intensity, and time of day. In step S10202, the initial light transmittance of the switchable glass may be adjusted in response to changes in the vehicle's environment.

[0222] Continuing to refer to FIG. 10 , optionally, in some exemplary embodiments of the present disclosure, in step S1050 , the method further includes: acquiring the distribution positions of the people in the vehicle.

[0223] In step S1070 and step S1090, the dimming glass that needs to adjust the light transmittance can be determined according to the distribution positions of the people in the vehicle.

[0224] 11 is a flow chart of a control method of a switchable glass system in energy-saving mode according to some exemplary embodiments of the present disclosure. In energy-saving mode, the control method includes steps S1110 to S1130.

[0225] 11 , in step S1110 , the vehicle driving mode selected by the user is obtained as the third vehicle driving mode, ie, the energy-saving mode.

[0226] In step S1120, at least one safety-related event is determined based on the determined third dimming mode. For example, the at least one safety-related event may be a vehicle turning, that is, in this step, it can be determined whether the vehicle is turning.

[0227] In step S1130, in response to at least one safety-related event satisfying a safety protection trigger condition, the light transmittance of at least one switchable glass is increased. For example, in response to the vehicle turning, the light transmittance of the switchable glass located on the front side window of the vehicle is increased. This can improve driving safety when turning.

[0228] Table 2 schematically illustrates the measured data for the vehicle's interior light intensity distribution under different sunroof opening and closing conditions. As shown in Table 2, the light intensity in the front row is largely unaffected by the sunroof opening or closing, while the light intensity in the rear row is significantly affected. The interior light intensity distribution is uneven, with the difference in light intensity between the front and rear rows reaching up to seven times, resulting in significant differences in the driver and passenger experience. In the front row, when the ambient light intensity is 15,000, the light intensity when viewed from the side is 3,000, resulting in a 1:5 contrast ratio between the interior and exterior. In the rear row, when the ambient light intensity is 16,000, the light intensity when viewed from the front is 700 (with the sunroof closed), resulting in a 1:25 contrast ratio between the interior and exterior, providing good privacy protection.

[0229] Table 2 Light intensity distribution inside the car

[0230] Table 3 schematically illustrates the measured data for privacy protection in the front and rear rows. As shown in Table 3, when viewed from the side, the light intensity in the front row is 3000, while the light intensity in the rear row is 650. This means that from a distance of 1-2 meters outside the vehicle, one can initially see what's happening in the front row, including whether there's someone in the front row, their gender, and the color of the seat. However, one cannot see what's happening in the rear row, indicating good privacy protection.

[0231] Table 3 Different light intensities in the front and back rows lead to different levels of privacy protection

[0232] Through actual measured data, the inventors have come to the following conclusions after research: (1) Safety is mainly related to the front side windows, especially when turning and changing lanes, the side windows need to be observed; (2) Privacy is mainly related to the rear side windows and rear windshield, and can also be related to the front side windows; when privacy protection is required for the front row, the front side windows need to use ultra-low transmittance glass, and the transmittance must be lower than that of the rear glass.

[0233] Based on this, an embodiment of the present disclosure also provides a control method for a dimming glass system for a vehicle. In this control method, multiple dimming modes can be provided separately in the vehicle, taking into account safety and privacy protection, making it convenient for users to control the dimming of the vehicle.

The second dimming mode may be a privacy dimming mode, in which privacy-related events are primarily detected and determined, and the rear side windows are dimmed based on the determination results. The third dimming mode may be a privacy dimming mode for the front and rear side windows, in which safety-related and privacy-related events are detected and determined, and the front side windows are dimmed based on the determination results of safety-related events, and the rear side windows are dimmed based on the determination results of privacy-related events.

[0244] In step S1340 , the light transmittance of the switchable glass is adjusted according to the transmittance adjustment information.

[0245] In step S1350, based on the first dimming mode selected by the user and the detection of the end of the safety-related event, the light transmittance of the front side windows of the vehicle is restored to the current light transmittance. For example, the current light transmittance can be the initial light transmittance in the first dimming mode or the current light transmittance of the front side windows set by the user.

[0248] In step S1420, a privacy-related event of the vehicle is detected. For example, the privacy-related event may include an event in which a person in the vehicle is resting or other vehicles are present near the vehicle.

[0249] In step S1430, according to the second dimming mode selected by the user and the occurrence of the privacy-related event detected, the transmittance adjustment information of the dimming glass on the vehicle is determined, for example, the light transmittance of the rear side window of the vehicle is reduced.

[0250] In step S1440 , the light transmittance of the switchable glass is adjusted according to the transmittance adjustment information.

[0251] In step S1450, based on the second dimming mode selected by the user and the detection of the end of the privacy-related event, the light transmittance of the rear side windows of the vehicle is restored to the current light transmittance. For example, the current light transmittance can be the initial light transmittance in the second dimming mode or the current light transmittance of the rear side windows set by the user.

[0252] 15 is a flow chart of a control method of a switchable glass system according to some other exemplary embodiments of the present disclosure when executing a third dimming mode. In this embodiment, the control method includes steps S1510 to S1550.

[0253] In step S1510 , a third dimming mode selected by a user from among n preset dimming modes is obtained.

[0254] In step S1520 , safety-related events and privacy-related events of the vehicle are detected.

[0255] In step S1530, according to the third dimming mode selected by the user and the occurrence of a safety-related event detected, the light transmittance of the front side window of the vehicle is increased.

[0256] In step S1540 , based on the third dimming mode selected by the user and the detection of the end of the safety-related event, the light transmittance of the front side window of the vehicle is restored to the current light transmittance.

[0257] In step S1550, according to the third dimming mode selected by the user and the occurrence of a privacy-related event, the light transmittance of the rear side window of the vehicle is reduced.

[0258] In step S1560 , based on the third dimming mode selected by the user and the detection of the end of the privacy-related event, the light transmittance of the rear window of the vehicle is restored to the current light transmittance.

[0259] In some exemplary embodiments, the method further includes: determining an initial light transmittance of the switchable glass according to a dimming mode selected by a user and an environment in which the vehicle is located.

[0260] For example, the initial light transmittance of the front side window of the vehicle is higher than the initial light transmittance of the rear side window of the vehicle.

[0261] Optionally, in some exemplary embodiments, the method further includes adjusting the current light transmittance of the switchable glass in response to user input. For example, the vehicle system may receive input from users in the front and rear rows and adjust the current light transmittance based on the user input.

[0262] In some embodiments of the present disclosure, a control method for a dimming glass system for a vehicle is also provided. In this control method, based on the vehicle's existing vehicle driving mode, respective safety options and / or privacy options are set for different vehicle driving modes to take into account both safety and privacy protection, thereby providing users with a better driving experience.

[0263] Figure 16 is a flow chart of a control method for a switchable glass system according to further exemplary embodiments of the present disclosure. In this embodiment, the control method includes steps S1610 to S1640. It should be noted that, unless there is a conflict, the methods and steps described in the above embodiments can be combined with this embodiment. The following description focuses on this embodiment, and other details can be referenced to the descriptions in the above embodiments and will not be repeated here.

[0264] In step S1610, a vehicle driving mode selected by a user from m preset vehicle driving modes is obtained, wherein the m vehicle driving modes respectively have their own security options and / or privacy options, and m is a positive integer greater than or equal to 2.

[0265] In step S1620 , according to the vehicle driving mode selected by the user, a safety option corresponding to the vehicle driving mode is determined.

[0266] Optionally or additionally, according to the vehicle driving mode selected by the user, a privacy option corresponding to the vehicle driving mode is determined.

[0267] In step S1630 , a safety-related event of the vehicle is detected.

[0268] Alternatively or additionally, a privacy-relevant event of the vehicle is detected.

[0269] In step S1640, in response to the safety-related event of the vehicle satisfying the triggering condition of the safety option corresponding to the vehicle driving mode, the light transmittance of the dimming glass is adjusted according to a dimming mode corresponding to one of the n dimming modes.

[0270] In response to the safety-related event of the vehicle not satisfying a trigger condition of a safety option corresponding to the vehicle driving mode, maintaining a light transmittance of at least one switchable glass on the vehicle unchanged, for example, maintaining it at an initial light transmittance or a current light transmittance.

[0271] Optionally or additionally, in step S1650, in response to the privacy-related event of the vehicle satisfying the triggering condition of the privacy option corresponding to the vehicle driving mode, the light transmittance of the dimming glass is adjusted according to a dimming mode corresponding to one of n dimming modes.

[0272] In response to the privacy-related event of the vehicle not satisfying the triggering condition of the privacy option corresponding to the driving mode of the vehicle, the light transmittance of at least one dimming glass on the vehicle is kept unchanged, for example, kept at an initial light transmittance or a current light transmittance.

[0273] In some embodiments of the present disclosure, the dimming modes described above can be combined with security / privacy options. That is, when a vehicle security / privacy-related event meets the triggering conditions of the corresponding security / privacy option, the light transmittance of the dimming glass can be adjusted according to one of the n dimming modes.

[0274] In some embodiments, the n dimming modes may include a first dimming mode, a second dimming mode, and a third dimming mode. The first dimming mode may be a safety dimming mode, in which safety-related events are primarily detected and determined, and the front side windows are dimmed based on the determination results. The second dimming mode may be a privacy dimming mode, in which privacy-related events are primarily detected and determined, and the rear side windows are dimmed based on the determination results. The third dimming mode may be a privacy dimming mode for the front and rear side windows, in which safety-related and privacy-related events are detected and determined, and the front side windows are dimmed based on the determination results of safety-related events, and the rear side windows are dimmed based on the determination results of privacy-related events.

[0275] In some embodiments, in step S1640, in response to the vehicle safety-related event satisfying a trigger condition of a safety option corresponding to the vehicle driving mode, the light transmittance of the dimming glass may be adjusted according to the first dimming mode. For example, the light transmittance of at least one dimming glass on the vehicle may be increased.

[0276] In step S1650, in response to the privacy-related event of the vehicle satisfying a trigger condition of a privacy option corresponding to the vehicle's driving mode, the light transmittance of the dimming glass may be adjusted according to the second dimming mode or the third dimming mode. For example, the light transmittance of at least one dimming glass on the vehicle may be reduced.

[0277] In some exemplary embodiments, the n dimming modes each have a fixed light transmittance or light transmittance range. That is, the n dimming modes each correspond to a fixed light transmittance or light transmittance range. When a user selects a vehicle driving mode, a dimming mode is mapped to the vehicle driving mode, and the corresponding fixed light transmittance or light transmittance range is determined by the dimming mode.

[0278] In some exemplary embodiments, the light transmittance or light transmittance range in the first dimming mode is higher than the light transmittance or light transmittance range in the second dimming mode. This design allows the light transmittance in sports mode to be higher than that in normal mode, thereby achieving a balance between safety in sports mode and privacy protection in normal mode.

[0279] In some exemplary embodiments, the light transmittance or the light transmittance range in the third dimming mode is between the light transmittance or the light transmittance range in the first dimming mode and the light transmittance or the light transmittance range in the second dimming mode.

[0280] In some embodiments of the present disclosure, the dimming mode may be considered in combination with the distribution position.

[0281] In some embodiments, in step S1640, the light transmittance of at least one dimming glass on the vehicle according to the first dimming mode among n dimming modes includes: obtaining the distribution positions of people in the vehicle; and determining the dimming glass that needs to implement light transmittance adjustment based on the distribution positions of people in the vehicle and the first dimming mode.

[0282] In some embodiments, in step S1650, the light transmittance of at least one dimming glass on the vehicle according to the second dimming mode or the third dimming mode among n dimming modes includes: obtaining the distribution positions of people in the vehicle; and determining the dimming glass that needs to implement light transmittance adjustment based on the distribution positions of people in the vehicle and the second dimming mode.

[0283] For example, improving the light transmittance of at least one switchable glass on the vehicle includes improving the light transmittance of the switchable glass of the side window located on the driver's side of the vehicle.

[0284] For example, reducing the light transmittance of at least one switchable glass includes reducing the light transmittance of the switchable glass of a side window located on the driver's side of the vehicle and a side window located near a passenger in the vehicle.

[0285] In some embodiments of the present disclosure, the light transmittance of the dimming glass near the position of the occupants in the vehicle can be adjusted based on the distribution of the occupants in the vehicle. For example, when there is a passenger in the left rear seat of the vehicle, the glass of the left rear window can be determined as the glass requiring light transmittance adjustment; when there is a passenger in the right rear seat of the vehicle, the glass of the right rear window can be determined as the glass requiring light transmittance adjustment; when there is a passenger in the middle rear seat of the vehicle, the glass of the two rear windows can be determined as the glass requiring light transmittance adjustment.

[0286] In some embodiments of the present disclosure, when adjusting the light transmittance according to the distribution positions of the people in the vehicle, it is also necessary to consider environmental factors such as weather and light intensity. For example, in a mode for the purpose of sunshade, "determining the light transmittance according to the distribution position" can include adjusting the light transmittance so that the glass near the people in the vehicle is at a low transmittance, thereby reducing the exposure of the people in the vehicle to external light. In a mode for partial protection of safe driving, for example, in order to avoid strong external light irritating the driver's eyes, the light transmittance of the driver's side window glass can be reduced. In a mode for the purpose of facilitating the observation of the external environment by the people in the vehicle, for example, it can be convenient for the driver to observe the surrounding vehicles when driving out of a dim basement, and it can be convenient for the rear passengers to sightsee the scenery during the journey. At this time, the light transmittance of the glass near the people in the vehicle can be increased.

[0287] Figure 17 is a schematic diagram of a vehicle using a switchable glass system according to an embodiment of the present disclosure, wherein Figure 17 is a top view of the vehicle. As shown in Figure 17, the switchable glass in the switchable glass system can include at least one of the vehicle's front windshield 51, rear windshield 52, sunroof 53, sun visor, and all side windshields 54. In other words, at least one of the vehicle's front windshield, rear windshield, sunroof, sun visor, and all side windshields can employ the switchable glass of the switchable glass system according to an embodiment of the present disclosure. Accordingly, the control method of the switchable glass system according to an embodiment of the present disclosure can be applied to such glass.

[0288] It should be noted that, in the embodiments of the present disclosure, some steps in the above manufacturing method may be performed individually or in combination, and may be performed in parallel or sequentially, and are not limited to the specific operation sequence shown in the figure.

[0289] Although some embodiments according to the general inventive concept of the present disclosure have been illustrated and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the general inventive concept of the present disclosure, the scope of which is defined by the claims and their equivalents.
