Abstract
Description
Technical Field
[0001] This application relates to the field of intelligent vehicle window control technology, and in particular to an intelligent vehicle window zoned light transmission control method and system. Background Technology
[0002] With the development of automotive intelligence, smart dimming glass technology is receiving increasing attention. It can dynamically adjust the light transmittance of windows through electrochromic processes, improving passenger comfort and protecting in-vehicle privacy. Current industry research focuses primarily on how to intelligently dim the windshield based on ambient light or driver status to improve visibility or reduce glare. However, intelligent adjustment solutions for side windows—areas closely related to passenger privacy and rearward visibility—are still lacking.
[0003] Existing side window dimming solutions are primarily limited to manual control or overall dimming based on ambient light intensity. While some high-end models are equipped with privacy glass that can change color throughout, this can only be manually switched between dark and transparent states by the driver, or the overall light transmittance can be automatically adjusted according to ambient light intensity. These solutions cannot detect the driver's dynamic operating intentions. When the vehicle uses dark privacy glass, the driver's side and rear view required to observe the exterior rearview mirrors in scenarios such as reversing and changing lanes will be obstructed by the dark side window, creating a blind spot. To address this, a few solutions have further attempted to set fixed transparent areas on the side windows to prevent obstruction of the view, but this fixed design will continuously expose the privacy inside the vehicle during daily driving. Therefore, existing side window dimming solutions cannot dynamically adjust according to driving scenarios, making it difficult to achieve a balance between privacy protection and visibility safety.
[0004] There is currently no effective solution to the problem that, while ensuring vehicle privacy, the side and rear visibility cannot be dynamically adjusted to achieve a balance between visibility safety and privacy in related technologies. Summary of the Invention
[0005] This application provides an intelligent window zone light transmission control method to solve the problem that related technologies cannot dynamically adjust the side and rear view while ensuring vehicle privacy, so as to achieve a balance between view safety and privacy.
[0006] In the first aspect, this application provides a method for controlling the light transmission of a smart window in a zone, applicable to vehicles with integrated smart windows; the smart window uses matrix electrochromic glass, and each smart window has a preset optical auxiliary area;
[0007] The method includes:
[0008] The trigger signal of the vehicle is acquired in real time; the trigger signal includes at least driving operation signals related to the vehicle's lateral visibility requirements and / or the vehicle's safety status signals.
[0009] Based on the type of the trigger signal, determine the smart window on the side of the vehicle to be adjusted, and the corresponding adjustment parameters;
[0010] Based on the adjustment parameters, the area and light transmittance of the optical auxiliary area corresponding to the smart window to be adjusted are adjusted.
[0011] In some embodiments, determining the smart window to be adjusted on the side of the vehicle, and the corresponding adjustment parameters, based on the type of the trigger signal, includes:
[0012] A mapping relationship is pre-established between the type of the trigger signal, the smart window to be adjusted, and the adjustment parameters;
[0013] When the type of the trigger signal is a driving operation signal related to the side view requirement, the corresponding smart window to be adjusted is determined to be the smart window on the driver's side and / or the smart window on the passenger side based on the mapping relationship, and the corresponding adjustment parameters are determined to be the first magnification coefficient and the first light transmittance.
[0014] When the type of the trigger signal is the safety status signal, the corresponding smart windows to be adjusted are determined to be all the smart windows on the side based on the mapping relationship, and the corresponding adjustment parameters are determined to be the second magnification coefficient and the second light transmittance.
[0015] In further embodiments, adjusting the area and light transmittance of the optical auxiliary area corresponding to the smart window to be adjusted based on the adjustment parameters includes:
[0016] When the trigger signal is a driving operation signal related to lateral visibility requirements, the first magnification factor and the first transmittance are dynamically determined based on the subtype of the driving operation signal; the current area of the optical auxiliary area is adjusted based on the first magnification factor, and the current transmittance of the optical auxiliary area is increased based on the first transmittance;
[0017] When the trigger signal is of the type of the safety status signal, the second amplification factor and the second transmittance are dynamically determined based on the subtype of the safety status signal; the current area of the optical auxiliary region is adjusted based on the second amplification factor, and the current transmittance of the optical auxiliary region is increased based on the second transmittance.
[0018] In further embodiments, adjusting the current area of the optical auxiliary region based on the first magnification factor and increasing the current transmittance of the optical auxiliary region based on the first transmittance includes:
[0019] The optical auxiliary area is located at the upper front part of the smart window on the driver's side and the smart window on the passenger side; the bottom edge length of the optical auxiliary area accounts for 15% to 20% of the width of the corresponding smart window, and the height accounts for 20% to 25% of the height of the corresponding smart window; the reference area is obtained at least based on the bottom edge length and the height.
[0020] When the subtype of the driving operation signal is a driver-side steering signal, the reference area is controlled to remain or be similarly amplified by 10% to 20% based on the corresponding first amplification factor;
[0021] When the subtype of the driving operation signal is the passenger-side turn signal, the reference area is similarly amplified by 20% to 30% based on the corresponding first amplification factor;
[0022] Based on the corresponding first transmittance, the optical auxiliary area is switched from a privacy state with a transmittance of less than 20% to a high transmittance state with a transmittance of not less than 70%.
[0023] In further embodiments, adjusting the current area of the optically auxiliary region based on the first magnification factor and increasing the current transmittance of the optically auxiliary region based on the first transmittance further includes:

[0025] Simultaneously switch the optical auxiliary areas corresponding to the smart window on the driver's side and the smart window on the passenger side from the privacy state to the high transparency state;
[0026] In response to the reverse gear signal switching to an exit reverse signal, based on a preset delay condition, the optical auxiliary areas corresponding to the smart windows on the driver's side and the smart windows on the passenger side are controlled to return to the privacy state.
[0027] In further embodiments, adjusting the current area of the optically auxiliary region based on the second magnification factor and increasing the current transmittance of the optically auxiliary region based on the second transmittance includes:
[0028] The optical auxiliary area occupies 100% of the corresponding smart window, the second magnification factor is 1.0, and the second light transmittance is not less than 90%.
[0029] When adjusting all the smart windows on the side based on the second magnification factor and the second light transmittance, all the smart windows on the side are switched from their original state to a fully transparent state with a light transmittance of not less than 90%.
[0030] When the subtype of the safety status signal is a collision signal or a vehicle posture abnormality signal, the second amplification coefficient and the second transmittance are directly executed to switch all the smart windows on the side to the fully transparent state and lock the fully transparent state.
[0031] When the subtype of the safety status signal is a voiceprint distress signal, verify whether the preset auxiliary triggering conditions are met; the auxiliary triggering conditions include at least one or more of the following: door lock status, collision signal, and abnormal vehicle posture signal;
[0032] When the auxiliary triggering condition is met, all the smart windows on the side are switched to the fully transparent state and the fully transparent state is locked.
[0033] Within a preset time after entering the fully transparent state, if a cancellation command is detected, all the smart windows on the control side are switched back to the original state.
[0034] In some embodiments, the method further includes a priority processing step:
[0035] When multiple trigger signals are acquired simultaneously, all trigger signals are arranged in descending order of preset priority.
[0036] Processing is performed on the trigger signal with the highest current priority in a single instance;
[0037] The first priority is the safety status signal, the second priority is the driving operation signal related to the vehicle's lateral visibility requirements, the third priority is the manual Override mode signal, and the fourth priority is the passenger personalized interaction signal.
[0038] The first priority is higher than the second priority, the second priority is higher than the third priority, and the third priority is higher than the fourth priority.
[0039] In some further embodiments, when the manual override mode signal is the highest priority trigger signal, the method further includes:
[0040] In response to the locking command of the physical switch triggered by the driver, the trigger signals corresponding to the second priority and the fourth priority are blocked;
[0041] Maintain the current light transmission state of all the smart windows until the locking command is released or the trigger signal corresponding to the first priority is responded to.
[0042] In further embodiments, when the passenger personalized interaction signal is a highest priority trigger signal, the method includes:
[0043] In response to a contact signal to the smart window; the contact signal must satisfy one or more of a preset pressure threshold, a preset area threshold, and a preset speed threshold;
[0044] When a closed pattern is detected based on the contact signal, the optical auxiliary area covered by the closed pattern is switched to a high-transmittance state with a transmittance of not less than 70%.
[0045] When a two-finger tap signal or a preset erase gesture signal is received, the optical auxiliary area covered by the closed graphic is switched to a privacy state with a light transmittance of less than 20%.
[0046] Secondly, this application provides an intelligent window zoned light transmission control system, applicable to vehicles with integrated intelligent windows; the intelligent window uses matrix electrochromic glass, and each intelligent window has a preset optical auxiliary area;
[0047] The system includes:
[0048] A multi-source state detection module is used to acquire the vehicle's trigger signals in real time, including at least driving operation signals related to the vehicle's lateral visibility requirements and / or the vehicle's safety status signals.
[0049] The central control unit communicates with the multi-source detection module and the matrix electrochromic glass respectively, and is used to execute the method described in any one of the first aspects.
[0050] Compared with related technologies, the embodiments of this application have the following beneficial effects:
[0051] This application embodiment acquires the vehicle's trigger signals in real time. These signals can comprehensively perceive the driver's operational intentions and the vehicle's safety status, providing multi-dimensional decision-making basis for subsequent precise adjustments. Based on the type of trigger signal, it determines the side-mounted intelligent window to be adjusted and its corresponding adjustment parameters, achieving differentiated responses to different signal sources. This ensures that the corresponding side window can be activated promptly when side-rear visibility is needed, and that a full vehicle response can be triggered in the event of a safety incident. Through a pre-configured optical auxiliary area, it maximizes window privacy while meeting visibility requirements. Furthermore, through dual control of area adjustment and light transmittance adjustment, it achieves dynamic and precise compensation for side-rear visibility. Therefore, this application embodiment can dynamically adjust side-rear visibility while ensuring vehicle privacy, fundamentally resolving the contradiction between visibility safety and privacy protection, and achieving a balance between the two.

[0070] This embodiment provides a method for controlling the light transmission of intelligent vehicle windows in different zones, applicable to vehicles integrated with intelligent windows. The intelligent windows utilize matrix electrochromic glass, and each intelligent window has a pre-set optical auxiliary area. This optical auxiliary area assists occupants in observing the outside environment, such as assisting the driver in viewing the exterior rearview mirrors or assisting passengers in viewing the scenery. By adjusting parameters to regulate the area and light transmittance of the optical auxiliary area, dynamic adjustment of the external field of vision is achieved under different driving scenarios, balancing privacy and driving safety.
[0071] Figure 2 This is a flowchart of the intelligent window zone light transmission control method in this embodiment, as follows: Figure 2 As shown, the process includes the following steps:
[0072] Step S210: Acquire the vehicle's trigger signals in real time; the trigger signals include at least driving operation signals related to the vehicle's lateral visibility requirements and / or the vehicle's safety status signals.
[0073] In this step, the vehicle trigger signals mentioned refer to various signal sources that can characterize the current state of the vehicle or the driver's intentions. Correspondingly, driving operation signals refer to vehicle control signals generated by the driver and related to lateral visibility requirements. Safety status signals refer to status signals related to vehicle and occupant safety.
[0074] Step S220: Based on the type of trigger signal, determine the smart window on the side of the vehicle to be adjusted, and the corresponding adjustment parameters.
[0075] This step distinguishes and identifies the trigger signals by type and matches them with corresponding adjustment strategies to achieve differentiated responses to multi-source trigger signals. This ensures that the corresponding smart windows can be accurately activated when external visibility is needed, and that a unified response of all smart windows in the vehicle can be triggered in the event of a safety incident.
[0076] Step S230: Adjust the area and light transmittance of the optical auxiliary area corresponding to the smart window to be adjusted based on the adjustment parameters.
[0077] This step, based on the adjustment parameters determined in step S220, drives the matrix electrochromic glass to precisely control the area and light transmittance of the optical auxiliary area on the smart window to be adjusted. Area adjustment refers to dynamically adjusting the size of the optical auxiliary area, while light transmittance adjustment refers to changing the light transmittance of that area. It should be understood that, to ensure vehicle driving safety, a basic area of the optical auxiliary area is preset to prevent mismatches between the optical auxiliary area and the scene when the driver adjusts it themselves due to a lack of understanding of the relevant parameters. This step, through the pre-configured optical auxiliary area, maximizes the preservation of window privacy while meeting external visibility requirements, and ensures flexible adjustment of the smart window's field of vision through dual control of area and light transmittance adjustment.
[0078] Through the above steps, this embodiment acquires the vehicle's trigger signal in real time. This trigger signal can comprehensively perceive the driver's operating intention and the vehicle's safety status, providing multi-dimensional decision-making basis for subsequent precise adjustments. Based on the type of trigger signal, the side intelligent window to be adjusted and its corresponding adjustment parameters are determined, realizing differentiated responses to different signal sources. This ensures that the corresponding side window can be activated in a timely manner when side and rear visibility is needed, and that a full vehicle response can be triggered in the event of a safety incident. By using a pre-configured optical auxiliary area, the privacy of the window is maximized while meeting visibility requirements. Through dual control of area adjustment and light transmittance adjustment, dynamic and precise compensation for side and rear visibility is achieved. Therefore, this embodiment can dynamically adjust side and rear visibility while ensuring vehicle privacy, fundamentally resolving the contradiction between visibility safety and privacy protection, and achieving a balance between the two.
[0079] In some embodiments, the method further includes an ambient light adaptive adjustment step:
[0080] Real-time monitoring of external light intensity;
[0081] The default base light transmittance of the smart windows is dynamically adjusted based on the light intensity:
[0082] When nighttime or low-light environments are detected, the default base transmittance will be set to 20% to 30%.
[0083] When daytime or high-light environments are detected, the default base transmittance will be set to 50% to 60%.
[0084] The default base transmittance serves as the starting reference value for all subsequent adjustment steps and can be automatically adjusted according to the environment without frequent manual intervention from the user.
[0085] In some embodiments, step S220, which involves determining the smart side window to be adjusted and its corresponding adjustment parameters based on the type of trigger signal, specifically includes the following steps:
[0086] Step S221: Pre-establish the mapping relationship between the type of trigger signal, the smart window to be adjusted, and the adjustment parameters.
[0087] In this step, a mapping table between trigger signal types and adjustment strategies is preset during the initialization phase. This allows for the association and binding of different types of trigger signals with the positions of the smart windows requiring adjustment and the corresponding adjustment parameters. This provides a decision-making basis for subsequent rapid response, ensuring that the corresponding adjustment strategy is quickly matched based on the trigger signal.
[0088] Step S222: When the type of the trigger signal is a driving operation signal related to the side view requirement, the corresponding smart window to be adjusted is determined to be the smart window on the driver's side and / or the smart window on the passenger side based on the mapping relationship, and the corresponding adjustment parameters are determined to be the first magnification coefficient and the first light transmittance.
[0089] In this step, when the trigger signal is identified as a driving operation signal, such as a turn signal or reverse gear signal, the window requiring adjustment is determined based on the mapping relationship to be the driver's side and / or passenger side smart window corresponding to the operating side. Simultaneously, the corresponding adjustment parameters are determined as a first magnification factor for adjusting the area of the optical auxiliary area and a first transmittance for setting the target light transmittance of the optical auxiliary area. This step, by associating the driving operation signal with the corresponding smart window, allows adjustment only on one or both sides where rearward visibility is needed, satisfying the driver's visibility requirements while maximizing the privacy of the smart window on the non-operating side.
[0090] Step S223: When the trigger signal is a safety status signal, the corresponding smart windows to be adjusted are determined to be all the smart windows on the side based on the mapping relationship, and the corresponding adjustment parameters are determined to be the second magnification coefficient and the second light transmittance.
[0091] In this step, when a trigger signal is identified as a safety status signal, such as a collision signal, an abnormal vehicle posture signal, or a voiceprint distress signal, the system determines that all the side windows need adjustment based on the mapping relationship. Simultaneously, the corresponding adjustment parameters are determined as the second magnification factor and the second light transmittance. This step, through a mechanism that triggers a full vehicle response to safety status signals, ensures that all side windows can respond and adjust promptly in an emergency, providing escape visibility for occupants and observation windows for external rescue personnel, embodying the paramount safety principle of prioritizing life.
[0092] In some further embodiments, when performing step S222, the driver-side smart window and the passenger-side smart window share a common first magnification factor and first transmittance. Specifically, when the vehicle is detected to be in reverse gear, the smart windows to be adjusted, as determined in step S222, are the driver-side and passenger-side smart windows. Both are treated with the same first magnification factor, maintaining a baseline area without additional magnification; simultaneously, they are treated with the same first transmittance, switching from a privacy state with transmittance below 20% to a high transmittance state with transmittance above 70%. The optical auxiliary areas of both windows are activated and restored synchronously, ensuring that the driver can obtain symmetrical and consistent rearward views through the left and right side rearview mirrors during reversing, meeting specific scenario requirements.
[0093] In some further embodiments, Figure 3 This is a flowchart of the adjustment process for the optical auxiliary region based on adjustment parameters provided in this embodiment. Please refer to it. Figure 3 Step S230, which is the step of adjusting the area and light transmittance of the optical auxiliary area corresponding to the smart window to be adjusted based on the adjustment parameters, specifically includes the following steps:
[0094] The type of trigger signal is determined based on the aforementioned steps.
[0095] Step S231: When the type of the trigger signal is a driving operation signal related to the side view requirement, dynamically determine the first magnification factor and the first transmittance based on the subtype of the driving operation signal; adjust the current area of the optical auxiliary area based on the first magnification factor, and increase the current transmittance of the optical auxiliary area based on the first transmittance.
[0096] This step dynamically determines adjustment parameters based on the subtype of driving operation signals, enabling differentiated responses to different steering scenarios. For example, for passenger-side steering with higher blind spot risk, a larger magnification factor can be used to expand the field of vision; for driver-side steering with lower blind spot risk, a smaller magnification factor can be used to balance privacy protection; and for reversing scenarios, both sides can be activated simultaneously while maintaining the baseline area. This refined adjustment method ensures that the intensity of vision compensation matches the actual blind spot risk, maximizing window privacy while ensuring safety.
[0097] Step S232: When the trigger signal is a safety status signal, dynamically determine the second amplification factor and the second transmittance based on the subtype of the safety status signal; adjust the current area of the optical auxiliary region based on the second amplification factor, and increase the current transmittance of the optical auxiliary region based on the second transmittance.
[0098] This step, by distinguishing and processing the subtypes of safety status signals, ensures that life-saving channels can be opened unconditionally in emergency situations, while effectively avoiding accidental triggering in non-emergency scenarios through auxiliary verification and cancellation mechanisms.
[0099] In some further embodiments, Figure 4 This is a flowchart illustrating the adjustment of the optical auxiliary region based on the first magnification factor and the first transmittance, provided in this embodiment. Please refer to it. Figure 4 In step S231, the step of adjusting the current area of the optical auxiliary region based on the first magnification factor and increasing the current transmittance of the optical auxiliary region based on the first transmittance specifically includes the following steps:
[0100] The optical auxiliary area is located at the upper front of the smart window on the driver's side and the smart window on the passenger side. The bottom edge of the optical auxiliary area accounts for 15% to 20% of the width of the corresponding smart window, and its height accounts for 20% to 25% of the height of the corresponding smart window. The reference area is determined based on at least the bottom edge length and height. This size range represents the optimal balance point derived from ergonomic experiments and driving simulation tests: when the bottom edge length is less than 15% of the window width, it cannot completely cover the outermost edge of the blind spot in the rearview mirror; when the bottom edge length is greater than 20%, the excessively transparent area significantly compromises privacy. Similarly, a height less than 20% cannot cover the upper and lower range of the blind spot, while a height greater than 25% will cover the sky area that the driver does not need to observe. The reference area, determined based on at least the bottom edge length and height, is the default size of the optical auxiliary area when not magnified.
[0101] Before making adjustments, first determine the subtype of the driving operation signal.
[0102] Step S231.1: When the subtype of the driving operation signal is the driving side steering signal, the control reference area is maintained or similarly amplified by 10% to 20% based on the corresponding first amplification factor.
[0103] In this step, since the driver is positioned on the driver's side, their line of sight to the same-side rearview mirror is more natural, and the blind spot is relatively small. Therefore, a smaller magnification factor is used to maximize the preservation of window privacy while ensuring the required left-side visibility. The aforementioned similarity magnification refers to proportionally increasing the base length and height based on the center of the area, maintaining the geometric similarity of the area's shape. For polygons, the length and width are magnified proportionally based on the center of the area.
[0104] Step S231.2: When the subtype of the driving operation signal is the passenger-side steering signal, the control reference area is similarly amplified by 20% to 30% based on the corresponding first amplification factor.
[0105] In this step, since the driver is on the driver's side, the viewing angle of the passenger side rearview mirror is limited, and the blind spot is larger and farther away. Therefore, a larger magnification factor is used to effectively eliminate the larger blind spot on the right rear, providing sufficient visibility for turning right.
[0106] Step S231.3: Based on the corresponding first transmittance, switch the optical auxiliary area from a privacy state with a transmittance of less than 20% to a high transmittance state with a transmittance of not less than 70%.
[0107] In this step, regardless of the subtype of the driving operation signal, the system switches between light transmittance states according to a preset first transmittance. Specifically, the privacy state with a transmittance of less than 20% effectively protects in-vehicle privacy and meets daily use needs; the high transmittance state with a transmittance of not less than 70% provides the driver with a clear optical field of vision, with a response speed far exceeding that of images displayed on electronic screens, eliminating the inherent latency issues of electronic systems. This step, through a quantified transmittance switching standard, ensures a reliable transition from privacy state to vision assistance state, providing the driver with direct visual feedback at the speed of light.
[0108] In further embodiments, when the subtype of the driving operation signal is a driver-side turn signal or a passenger-side turn signal, the reference area of the optical auxiliary area on the driver-side smart window is maintained or similarly enlarged by 10% to 20%, while the reference area of the optical auxiliary area on the passenger-side smart window is similarly enlarged by 20% to 30%. This ensures that the entire rear-side field of vision is adequate.
[0109] In some further embodiments, the principle for determining the reference area of the optically assisted region includes:
[0110] Using the driver's eyes as the observation point The center of the rearview mirror's reflective surface is The car window glass is the projection surface. The driver's line of sight for observing road conditions to the side and rear is as follows: to to Based on the principle of similar triangles, the minimum area of the transparent region required to completely cover the projection of the blind spot of the rearview mirror onto the car window is determined. At the driver's eye level rearview mirror width Proportional to the distance between the rearview mirror and the eyes. Inversely proportional: This area is necessarily located at the upper front of the car window, and can naturally form a triangle or fan shape. It can achieve the maximum blind spot coverage efficiency with the smallest transparent area, ensuring that the lateral blind spot is completely eliminated while preserving the privacy of the car window to the greatest extent.
[0111] In some further embodiments, the reference area of the optical assistance region allows the driver to customize and fine-tune it according to their seating posture, eye height, and blind spot requirements; the method also includes a dynamic threshold limiting step:
[0112] Real-time monitoring of the driver's manual adjustments to the optical assistance area;
[0113] When the optical auxiliary area is manually reduced, if the adjusted area is less than 80% of the reference area, the adjustment operation will be automatically locked or a safety warning will be issued, and the area will be forcibly maintained at 80% of the reference area.
[0114] When the optical auxiliary area is manually enlarged, if the adjusted area is greater than 150% of the reference area, it will automatically limit its further expansion and force it to remain at 150% of the reference area.
[0115] This step, by setting a lower threshold of 80% and an upper threshold of 150%, gives drivers the freedom to make personalized adjustments based on their own seating posture, while ensuring that blind spots are not exceeded or privacy is not excessively exposed under any circumstances.
[0116] In some further embodiments, after switching the optically aided region to a high-transmittance state based on a first transmittance, the method further includes a reversal recovery step:
[0117] In response to the turn signal returning to normal, the optical assist area is restored to privacy mode after a 1-second delay;
[0118] If a turn signal from the same side is detected again within a 1-second delay, the high-transmission state of the optical auxiliary area will be maintained until the turn operation is completed.
[0119] This step, through a delayed recovery mechanism and continuous lane change holding logic, avoids frequent switching caused by the turn signal briefly returning to center and then immediately activating again, providing consistent vision assistance for scenarios such as continuous lane changes and improving the user experience.
[0120] In some further embodiments, Figure 5 This is a flowchart illustrating the adjustment of the optical auxiliary area when the trigger signal is a reverse gear signal, as provided in this embodiment. Please refer to it. Figure 5 In step S231, the step of adjusting the current area of the optical auxiliary region based on the first magnification factor and increasing the current transmittance of the optical auxiliary region based on the first transmittance specifically includes the following steps:
[0121] When the subtype of the driving operation signal is the reverse gear signal, the corresponding optical auxiliary areas of the smart window on the driver's side and the smart window on the passenger side are activated simultaneously, and the reference area of the corresponding optical auxiliary area is maintained based on the corresponding first magnification factor.
[0122] In this step, the reference area refers to the region mentioned in the previous embodiment, where the bottom edge length accounts for 15% to 20% of the corresponding side window width, and the height accounts for 20% to 25% of the corresponding side window height. This step, by setting a control strategy for simultaneous activation of both sides while maintaining the reference area in the reversing scenario, ensures symmetry in the left and right field of vision during reversing, eliminating the need for the driver to adapt to different light transmission conditions on both sides. Furthermore, this step maintains the reference area rather than enlarging it because the driver needs to pay attention to both sides simultaneously when reversing; a proven reference area is sufficient to cover the rearview mirror's field of vision requirements, while excessive enlargement would unnecessarily sacrifice privacy protection.
[0123] Simultaneously switch the optical auxiliary areas of the smart windows on both the driver's and passenger's sides from privacy mode to high transparency mode.
[0124] In this step, the matrix-type electrochromic glass is driven to simultaneously switch the transmittance of the optical auxiliary areas on the driver's and passenger's side smart windows. Specifically, by simultaneously switching to a high-transmittance state on both sides, the driver is provided with complete rear visibility. In scenarios requiring frequent left and right observation, such as reversing into a parking space or parallel parking, simultaneous transparency on both sides allows the driver to quickly obtain information from both sides without waiting for the switching to complete on one side, effectively improving the continuity and safety of reversing operations.
[0125] In response to the reverse gear signal switching to the exit reverse signal, based on preset delay conditions, the optical auxiliary areas corresponding to the smart windows on the driver's side and the smart windows on the passenger side are restored to privacy mode.
[0126] This step, through a delayed recovery mechanism, fully considers the actual continuity of the reversing operation and the driver's visual adaptation needs. After reversing, the driver usually needs a brief moment to check the surrounding environment or prepare for the next operation. Immediately restoring the privacy state may cause a sudden darkening of the field of vision, resulting in temporary discomfort or misjudgment. Reverting to the privacy state based on preset delay conditions provides the driver with a natural visual transition.
[0127] In some specific embodiments, the preset delay condition can be set to a delay of 3 to 5 seconds.
[0128] In some further embodiments, the reference area of the optical assistance region supports driver-customized adjustment; the method also includes a dynamic threshold limiting step.
[0129] When the driver manually reduces the optical assist area, if the adjusted area is less than 80% of the reference area, the adjustment operation will be automatically locked or a safety warning will be issued, and the area will be forcibly maintained at 80% of the reference area.
[0130] When the driver manually increases the optical assist area, if the adjusted area is greater than 150% of the reference area, the driver will automatically limit its further expansion and force it to remain at 150% of the reference area.
[0131] In some further embodiments, Figure 6 This is a flowchart illustrating the adjustment of the optical auxiliary region based on the second magnification factor and the second transmittance, provided in this embodiment. Please refer to it. Figure 6 In step S232, the step of adjusting the current area of the optical auxiliary region based on the second magnification factor and increasing the current transmittance of the optical auxiliary region based on the second transmittance specifically includes the following steps:
[0132] The optical auxiliary area occupies 100% of the corresponding smart window, the second magnification factor is 1.0, and the second light transmittance is not less than 90%.
[0133] Based on the above design, the optical assistance area occupies 100% of the corresponding smart window area, meaning the entire side window is considered the area requiring adjustment. The second magnification factor is fixed at 1.0, indicating that no selective magnification is applied to any local area, but rather directly to the entire window. The second light transmittance is set to a fully transparent state of no less than 90% to ensure maximum visibility for rescue operations.
[0134] In step S232.1, when adjusting all the smart windows on the side based on the second magnification factor and the second light transmittance, all the smart windows on the side are switched from their original state to a fully transparent state with a light transmittance of not less than 90%.
[0135] In this step, based on the determined second magnification factor and second light transmittance, the matrix electrochromic glass is driven to uniformly adjust all side smart windows. Regardless of the current light transmittance of the windows, they are forcibly switched to a fully transparent state with a light transmittance of no less than 90%, ensuring that all side windows can uniformly and quickly enter the highest transparency state in an emergency, providing escape visibility for the occupants.
[0136] In step S232.2, when the subtype of the safety status signal is a collision signal or an abnormal vehicle posture signal, the second amplification factor and the second transmittance are directly executed to switch all the smart windows on the side to a fully transparent state and lock the fully transparent state.
[0137] This step involves considering collision signals such as airbag deployment and acceleration exceeding a preset threshold, as well as abnormal vehicle posture signals such as vehicle rollover, prolonged inversion, and rapid sinking. This step establishes an unconditional trigger mechanism for collisions and posture anomalies to ensure that the fully transparent state is automatically activated even in extreme situations where occupants may lose consciousness or be unable to actively call for help. The design of locking the fully transparent state prevents accidental deactivation due to subsequent misoperation or vehicle interference.
[0138] Step S232.3: When the subtype of the safety status signal is a voiceprint distress signal, verify whether the preset auxiliary triggering conditions are met; the auxiliary triggering conditions include at least one or more of the following: door lock status, collision signal, and abnormal vehicle posture signal.
[0139] This step introduces multiple auxiliary triggering conditions to prevent false triggering caused by in-car entertainment or children imitating voiceprint recognition alone, while also ensuring accurate response in real distress scenarios. It should be understood that... Figure 6 The attached diagram is for illustrative purposes only. In actual operation, the order of steps S232.2 and S232.3 can be set according to requirements. For example, first detect whether there is an audible distress signal, and then determine the auxiliary conditions and collision signal. In this case, the collision signal and the abnormal vehicle posture signal can be merged into the auxiliary triggering conditions.
[0140] Step S232.4: When the auxiliary triggering conditions are met, switch all the smart windows on the side to the fully transparent state and lock the fully transparent state.
[0141] This step ensures that a rescue response of the same level as a physical collision can be provided when occupants actively request help and safety conditions are met, creating a clear escape route for the occupants.
[0142] Step S232.5: Within a preset time after entering the fully transparent state, when a cancellation command is detected, control all the smart windows on the side to switch back to their original state.
[0143] In this step, a mechanism to prevent accidental activation and restore the vehicle's transparency triggered by a voiceprint distress signal is implemented. Within a preset timeframe after entering the fully transparent state, such as 3 seconds, if a user-issued cancellation command is detected, such as a preset voice command to cancel, close, or restore to normal, or if a door unlocking action is detected, the emergency mode is immediately terminated, and all side smart windows are restored to their previous translucent state to remedy the extremely low probability of accidental activation.
[0144] In some preferred embodiments, Figure 7 This is a flowchart of priority processing for trigger signals provided in this embodiment. Please refer to it. Figure 7In conjunction with the foregoing embodiments and specific implementation methods, the method further includes a priority processing step, specifically including the following processing steps:
[0145] When multiple trigger signals are acquired simultaneously, all trigger signals are arranged in descending order of preset priority.
[0146] In this step, when multiple trigger signals are received simultaneously, instead of parallel processing or random response, a priority arbitration mechanism is activated. By establishing a unified priority sorting mechanism, conflicts between trigger signals from multiple sources are prevented, ensuring smooth response and adjustment even in complex scenarios.
[0147] Processing is performed on the highest priority trigger signal at a time.
[0148] The first priority is the safety status signal, the second priority is the driving operation signal related to the vehicle's side visibility requirements, the third priority is the manual Override mode signal, and the fourth priority is the passenger personalized interaction signal.
[0149] This step clearly defines a four-level priority system. The first priority is safety status signals, including collision signals, abnormal vehicle posture signals, and voiceprint distress signals that have been verified. The second priority is driving operation signals, including turn signal signals and reverse gear signals. The third priority is manual override mode signals, which are locking commands triggered by the driver through a physical switch. The fourth priority is passenger personalized interaction signals, including entertainment operations such as touch drawing on the windows.
[0150] First priority is higher than second priority, second priority is higher than third priority, and third priority is higher than fourth priority.
[0151] This step prioritizes various trigger signals, placing life-saving signals at the highest priority, dynamic driving safety signals at the second highest priority, manual intervention at the third highest priority, and personalized entertainment needs at the lowest priority.
[0152] In some further embodiments, when the subtype of the driving operation signal includes both a reverse gear signal and a turn signal, the method further includes a composite scenario processing step:
[0153] Prioritize the reversing logic, which means simultaneously activating the optical auxiliary areas corresponding to the driver's side smart window and the passenger side smart window;
[0154] The optical auxiliary areas on both sides are switched from privacy mode to high transparency mode at the same time, and are logically superimposed without following the steering wheel rotation to form a wide-angle panoramic field of view.
[0155] After the reverse gear signal is disengaged, the corresponding steering assist adjustment is executed according to the continuous state of the steering signal.
[0156] In some further embodiments, when the first priority trigger signal is a collision signal or a vehicle posture abnormality signal, the method further includes an occupant awareness confirmation step:
[0157] Initiate an occupant awareness confirmation window, which lasts for 3 to 5 seconds;
[0158] During the confirmation window, occupant feedback signals are continuously monitored. Occupant feedback signals include one or more of the following: voice commands, physical operations, and active distress calls.
[0159] If no occupant feedback signal is detected within the confirmation window, the occupant is determined to be unconscious, and step S232.2 of full vehicle transparency and locking is executed;
[0160] If an active distress call voiceprint is detected in the occupant's feedback signal during the confirmation window, then the full vehicle transparency and locking steps of S232.2 are executed immediately.
[0161] If a rejection of transparency command is detected in the occupant's feedback signal during the confirmation window period, the emergency rescue process will be terminated, and the current window transparency will be maintained.
[0162] In some further embodiments, after step S232.2, the method further includes the following steps:
[0163] After switching all the smart side windows to full transparency and locking them, all other adjustment commands triggered by other signals are blocked, including central control screen touch adjustment, physical button adjustment, and voice command adjustment, until the vehicle is completely powered off or the emergency state is lifted.
[0164] In some further embodiments, Figure 8 This is the adjustment flowchart provided in this embodiment when the manual override mode signal is the current highest priority trigger signal. Please refer to it. Figure 8 The process includes the following steps:
[0165] In response to the driver's triggering of a physical switch locking command, the trigger signals corresponding to the second and fourth priorities are blocked.
[0166] In this step, the manual Override mode is the well-known manual overdrive mode in the field. The physical switch mentioned can be a dedicated button on the steering wheel, center console, or door, used to manually lock the window's light transmission status. Upon receiving the lock command, all trigger signals corresponding to the second and fourth priorities are actively blocked, meaning that turn signal signals, reverse gear signals, and passenger touch drawing requests are no longer responded to. By blocking low-priority signals, it ensures that the driver's manually set window status will not be accidentally changed by the automatic adjustment function, giving the driver absolute control over the window's light transmission status in specific scenarios.
[0167] For example, when it is necessary to conduct important business meetings or take a break through dark privacy glass, the driver can lock the current status with one button to avoid the privacy environment being compromised due to accidental activation of the turn signal or accidental touch by the passenger.
[0168] Maintain the current light transmission state of all smart windows until the locking command is released or the trigger signal corresponding to the first priority is responded to.
[0169] This step achieves a balance between manual control and automatic safety by setting two exit mechanisms. Maintaining the current state until manually released fully respects the driver's intention to manually control the vehicle; allowing the first-priority signal to interrupt the lock ensures that life-saving rescue has the highest priority in any situation, avoiding delays in rescue due to manual locking.
[0170] In some further embodiments, Figure 9 This is a flowchart illustrating the adjustment process when the passenger personalized interaction signal is the highest priority trigger signal, as provided in the embodiment. Please refer to it. Figure 9 The specific steps of this process are as follows:
[0171] Responding to a contact signal to the smart window; the contact signal must meet one or more of the preset pressure threshold, preset area threshold, and preset speed threshold.
[0172] In this step, when the passenger's personalized interaction signal is determined to be the highest priority trigger signal through priority arbitration, the touch monitoring mode is activated. The pressure-sensing layer and touch layer integrated into the smart window detect the passenger's touch operations in real time and perform multi-dimensional filtering on the contact signals: a pressure threshold is used to distinguish between intentional pressing and unintentional light touches (e.g., a force greater than 50 grams is considered valid); an area threshold is used to exclude overly subtle touches (e.g., contact points with a diameter less than 2cm do not respond); and a speed threshold is used to filter out actions not intended for drawing, such as rapid waving. Only when the contact signal simultaneously meets or at least meets multiple preset threshold conditions is it recognized as a valid touch intent and proceeds to the next step. By introducing a multi-dimensional anti-accidental touch mechanism, unintentional touches such as children slapping, clothing friction, and rapid waving are effectively filtered out.
[0173] When a closed pattern is detected based on the contact signal, the optical auxiliary area covered by the closed pattern is switched to a high-transmittance state with a transmittance of not less than 70%.
[0174] In this step, valid touch trajectories are tracked and analyzed in real time. When a passenger's finger swipe trace forms a closed shape, such as a circle, rectangle, ellipse, or irregular closed curve, the built-in pattern recognition algorithm confirms the closed shape and calculates the coordinate range of the matrix electrodes covered by the shape. Subsequently, the matrix electrochromic glass is driven to apply a transparent voltage only to the pixels inside the closed shape, switching that area from a privacy state with a light transmittance of less than 20% to a high-transmittance state with a light transmittance of not less than 70%, forming a so-called movable peephole, while the rest of the window maintains its original privacy state. This step, through closed shape recognition and local high-transmittance control, allows passengers to draw transparent areas of any size and location to view the scenery or observe the external environment according to their needs, without sacrificing the privacy of the entire window, greatly enhancing the riding experience and personalized interactive fun for rear passengers.
[0175] When a two-finger tap signal or a preset erase gesture signal is received, the optical auxiliary area covered by the closed graphic is switched to a privacy state with a light transmittance of less than 20%.
[0176] This step also monitors specific gestures used to clear the currently transparent area. For example, when preset erasure gestures such as two-finger taps, X-shaped smears, or quick triple taps are detected, it indicates that the passenger wishes to close the currently created peephole. The previous graphic control command is immediately revoked, and the originally highly transparent closed graphic area is switched back to a privacy state with a light transmittance of less than 20%, restoring the entire window to its uniform privacy appearance before drawing.
[0177] In this embodiment, the matrix electrochromic glass adopts an orthogonal grid-like electrode layout, including row electrodes arranged horizontally along the width direction of the window and column electrodes arranged vertically along the height direction of the window, forming an array of independent controllable pixels with a pixel density of 4×4 to 10×10 pixels per square centimeter.
[0178] When identifying closed shapes based on contact signals, the Bresenham line algorithm is used to calculate the coordinates of the pixels that constitute the boundary of the shape, and the scan line filling algorithm is executed to identify the pixels inside the boundary, achieving sub-millimeter precision control for any irregular shape.
[0179] In some further embodiments, the matrix electrochromic glass uses a dark-colored material when power is off, and the vehicle is equipped with a supercapacitor energy storage module; when a serious collision occurs and the main power is cut off, the supercapacitor releases its stored energy, forcibly driving all side smart windows to switch to a fully transparent state.
[0180] This embodiment also provides an intelligent window zoned light transmission control system, which is suitable for vehicles with integrated intelligent windows; the intelligent window adopts matrix electrochromic glass 1000, and each intelligent window has a preset optical auxiliary area.
[0181] Figure 10 This is a block diagram of an intelligent vehicle window zoned light transmission control system provided in one embodiment of this application. Please refer to... Figure 10 The system includes the following structure:
[0182] The multi-source state detection module 1010 is used to acquire the vehicle's trigger signals in real time, including at least driving operation signals related to the vehicle's lateral visibility requirements and / or the vehicle's safety status signals.
[0183] The central control unit 1020 communicates with the multi-source detection module and the matrix electrochromic glass 1000 respectively, and is used to execute the steps shown in the aforementioned method embodiments and their specific implementations. Details already described will not be repeated.
[0184] In some embodiments, the system further includes the following modules:
[0185] A multi-source state detection module is used to acquire vehicle trigger signals in real time. These trigger signals include at least driving operation signals related to the vehicle's lateral visibility requirements and / or vehicle safety status signals. Specifically, the multi-source state detection module includes:
[0186] The driving operation signal acquisition subunit is connected to the vehicle's CAN bus and is used to acquire driving operation signals related to side visibility requirements, such as turn signal and reverse gear signal, in real time.
[0187] The safety status signal acquisition subunit includes a collision sensor, a vehicle attitude sensor, and an in-vehicle microphone array, which are used to acquire collision signals, abnormal vehicle attitude signals, and in-vehicle voiceprint signals.
[0188] The touch interaction signal acquisition subunit is connected to the window touch layer and is used to acquire the touch operation signals of passengers.
[0189] This module uses multiple sensors and signal acquisition channels to achieve comprehensive perception of vehicle status, driver intentions, and passenger needs, providing a rich data foundation for subsequent intelligent decision-making.
[0190] In some further embodiments, matrix-type electrochromic glass is deployed on all side smart windows of the vehicle. The matrix-type electrochromic glass employs an orthogonal grid-like electrode layout, specifically including:
[0191] A glass substrate, comprising an outer glass layer and an inner glass layer, and an electrochromic material layer sandwiched between them;
[0192] The matrix electrode layer includes multiple row electrodes arranged horizontally along the width of the window and multiple column electrodes arranged vertically along the height of the window. The row electrodes and column electrodes are insulated from each other by an insulating layer at their intersections, forming an array of independent and controllable pixels. The row electrodes are preferably made of silver nanowire material with a linewidth controlled between 5 μm and 10 μm. The column electrodes are preferably made of indium tin oxide material with a linewidth controlled between 10 μm and 20 μm.
[0193] With a pixel density of 4×4 to 10×10 pixels per square centimeter, it is sufficient to achieve sub-millimeter-level edge control precision for optically aided areas and passenger-drawn graphics.
[0194] A touch-sensing layer, integrated into the glass surface or interlayer, is used to detect passenger touch operations, including pressure sensing units and position sensing units.
[0195] In some further embodiments, the system also includes a central control unit, communicatively connected to both the multi-source state detection module and the matrix electrochromic glass. The central control unit includes:
[0196] The signal receiving subunit is used to receive various trigger signals collected by the multi-source state detection module.
[0197] The priority arbitration subunit is used to arbitrate multiple trigger signals according to a preset priority rule when multiple trigger signals are received simultaneously, and to determine the trigger signal with the highest priority. In the priority rule, the priority of safety status signals related to life rescue is higher than the priority of driving operation signals related to side visibility requirements, the priority of driving operation signals related to side visibility requirements is higher than the priority of manual override mode signals, and the priority of manual override mode signals is higher than the priority of passenger personalized interaction signals.
[0198] The mapping relationship storage subunit is used to store the pre-established mapping relationship between the trigger signal type, the smart window to be adjusted, and the adjustment parameters;
[0199] The control command generation subunit is used to generate corresponding control commands based on the determined highest priority trigger signal, by calling the mapping relationship. The control commands include the identifier of the smart window to be adjusted, the area adjustment parameters of the optical auxiliary area, and the light transmittance adjustment parameters.
[0200] The graphics processing subunit is used to recognize and process touch trajectories in the passenger personalized interaction mode. It uses the Bresenham line algorithm to calculate the pixel coordinates that form the boundary of the closed graphic, and executes the scan line fill algorithm to identify the pixels inside the boundary and generate corresponding pixel control commands.
[0201] In some further embodiments, the system also includes:
[0202] The driving circuit, connected between the central control unit and the matrix electrochromic glass, is used to apply driving voltage to the corresponding row and column electrodes according to the control instructions generated by the central control unit, so that the pixels in the target area undergo electrochromic reactions, thereby achieving precise control over the area and transmittance of the optical auxiliary area.
[0203] The supercapacitor energy storage module, electrically connected to the matrix-type electrochromic glass, is used to provide emergency power when the vehicle's main power is cut off. Specifically, when using a power-off dark-colored electrochromic material, if a serious collision causes the main power to be cut off, the supercapacitor releases its stored energy, forcibly driving all side smart windows to switch to a fully transparent state, ensuring rescue visibility in emergency situations.
[0204] A pressure-sensing layer, integrated into the touch-sensing layer of the matrix electrochromic glass, is used to detect the pressure value of touch operations. The central control unit is also equipped with an anti-mistouch filtering subunit, which filters touch operations based on preset pressure thresholds, area thresholds, and speed thresholds. Only when a touch operation simultaneously meets or at least meets multiple preset threshold conditions is it recognized as a valid touch intent.

Although the apparatus described in this embodiment is preferably implemented in software, hardware implementation, or a combination of software and hardware, is also possible and contemplated.
[0206] Through the aforementioned system, this embodiment achieves refined zoned light transmission control of the side smart windows. The multi-source status detection module comprehensively perceives the vehicle status and user intent; the central control unit generates precise control commands through priority arbitration and mapping relationships; the matrix-type electrochromic glass, in conjunction with the driving circuit, achieves independent control of the area and light transmittance of the optical auxiliary area; the supercapacitor energy storage module provides reliable power-off protection in emergencies; and the pressure-sensing layer and anti-accidental touch filtering mechanism ensure the accuracy and reliability of personalized interaction.
