[0004] Smart glass is a new type of optoelectronic glass product that can change its light transmittance according to the received voltage or current signal. With the development of intelligent, electric, and connected equipment, smart glass is widely used in various devices to achieve adjustable light transmittance.

[0005] However, the transmittance of current smart glass is mainly adjusted manually or automatically after a change in ambient brightness is detected, which results in problems such as untimely adjustment and lack of flexibility. Summary of the Invention

[0006] This application provides a method, system, vehicle, and electronic device for controlling dimming glass, which facilitates flexible adjustment of the light transmittance of dimming glass and enhances the user experience.

[0007] In a first aspect, a method for controlling dimming glass is provided, comprising:

[0008] The target light intensity and the current ambient light intensity are obtained. The current ambient light intensity is the light intensity of the environment in which the mobile device is located at the current moment. The target light intensity is the light intensity of the target road segment in which the mobile device is located during the target time period. The target time period is the time period after the current moment.

[0009] Based on the difference between the target light intensity and the current ambient light intensity, it is determined whether to adjust the transmittance of the dimming glass of the mobile device in advance. The advance adjustment means adjusting the transmittance of the dimming glass of the mobile device before the mobile device moves to the target road segment.

[0010] If it is determined that advance adjustment is to be performed, a first command is sent to the dimming glass of the mobile device.

[0011] Secondly, a method for controlling a dimming glass, the method comprising:

[0012] Determine the estimated transit time of the mobile device in the target area within the target time period;

[0013] Determine whether the estimated transit time exceeds the third time threshold;

[0014] If the expected transit time exceeds the third time threshold, the light transmittance of the dimming glass of the mobile device is adjusted.

[0015] If the expected transit time does not exceed the third time threshold, the light transmittance of the dimming glass of the mobile device will not be adjusted.

[0016] Thirdly, a method for controlling dimming glass, the method comprising: determining a first ambient light intensity and a second ambient light intensity of a target road segment in which a mobile device is located during a target time period;

[0017] The target transmittance is determined based on the first ambient light intensity and the second ambient light intensity.

[0018] The dimming glass of the mobile device sends a transmittance adjustment command, wherein the transmittance adjustment quality is used to indicate that the transmittance of the dimming glass is adjusted to the target transmittance.

[0019] Fourthly, a light transmittance control system for a dimming glass is provided, applied to perform the method of controlling the dimming glass as described in the first aspect, the system comprising:

[0020] The light intensity acquisition module is used to acquire the target light intensity and the current ambient light intensity. The current ambient light intensity is the light intensity of the environment in which the mobile device is located at the current moment. The target light intensity is the light intensity of the target road segment in which the mobile device is located during the target time period. The target time period is the time period after the current moment.

[0021] The advance adjustment judgment module is used to determine whether to adjust the light transmittance of the dimming glass of the mobile device in advance based on the difference between the target light intensity and the current ambient light intensity. The advance adjustment means adjusting the light transmittance of the dimming glass of the mobile device before the mobile device moves to the target road segment.

[0022] The instruction sending module is used to send a first instruction to the dimming glass of the mobile device when it is determined that an advance adjustment is to be made.

[0023] Fifthly, a vehicle is provided, the vehicle comprising: a dimming glass and a dimming glass transmittance control system, the dimming glass transmittance control system being used to perform the steps of the method for controlling the dimming glass as described in the first, second, or third aspects.

[0024] A sixth aspect provides an electronic device including a processor and a memory, the memory storing a program or instructions executable on the processor, the program or instructions, when executed by the processor, implementing the steps of a method for controlling a dimming glass as described in the first, second, or third aspect.

[0025] In a seventh aspect, a readable storage medium is provided, on which a program or instructions are stored, which, when executed by a processor, implement the steps of the method for controlling a dimming glass as described in the first, second, or third aspect.

[0026] Eighthly, a chip is provided, the chip including a processor and a communication interface coupled to the processor, the processor being configured to run a program or instructions to implement the steps of the method for controlling a dimming glass as described in the first, second, or third aspects.

[0027] A ninth aspect provides a computer program / program product stored in a storage medium, the computer program / program product being executed by at least one processor to implement the steps of the method for controlling a dimming glass as described in the first, second, or third aspect.

[0028] In this embodiment, by acquiring the target light intensity (the light intensity of the target road segment where the mobile device is located during the target time period) and the current ambient light intensity (the light intensity of the environment in which the mobile device is located at the current moment), the difference between the two is used to determine whether to adjust the light transmittance of the mobile device's dimming glass in advance. This avoids the problem of adjusting the light transmittance of the dimming glass only after the ambient light intensity has changed, i.e., after the user has already been adversely affected by the change in light intensity (e.g., feeling glare when suddenly entering a bright environment from a dark environment). This allows for flexible control of the light transmittance of the dimming glass, improving the user experience. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

It should be understood that such terms can be used interchangeably where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of the same class, not limited in number; for example, the first object can be one or at least two. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0038] Smart glass is an important development direction for automotive glass. Currently, the main types of smart glass include: electrochromic (EC), polymer liquid crystal, dye liquid crystal, and suspended particles. Among them, electrochromic smart glass is a very important type of smart glass, with advantages such as low cost, infrared reflection capability, infrared resistance, and ease of achieving irregular shapes. However, it also has disadvantages such as slow response time and poor durability (easily failing after multiple dimming cycles). Electrochromism works by applying a voltage to the electrodes at both ends of the element. Under the influence of the electric field of the applied voltage, particles migrate into (or out of) the electrochromic layer, causing the valence number of the electrochromic material to decrease (or increase). Before equilibrium, the electrochromic material changes color; after equilibrium, the color of the electrochromic material stabilizes. Polymer liquid crystal works by adding a liquid crystal dimming film between the glass panes. When electricity is applied, the polymer liquid crystal material in the liquid crystal film aligns in an orderly manner, making the glass transparent; conversely, it appears translucent but not transparent. Different types of smart glass have different driving voltages and different response speeds. The dimming glass mentioned in the following embodiments of this application can be any of the above-described glass types.

[0039] However, current dimming glass primarily adjusts its transmittance manually or automatically after detecting changes in ambient brightness. This approach suffers from delayed and inflexible adjustments. Specifically, in the automatic dimming mode of mobile devices, the device can automatically adjust its transmittance based on light intensity information captured by a light sensor, keeping the internal light intensity within a relatively stable range and avoiding problems such as direct glare and strong light. For example, in reading mode, the internal light intensity is maintained within a first light intensity range; in movie mode, it's maintained within a second light intensity range; in sleep mode, it's maintained within a third light intensity range; and in custom mode, it's maintained within a fourth light intensity range. However, this adjustment scheme (adjusting transmittance solely based on real-time light intensity information) only adjusts the transmittance of the dimming glass after changes in ambient light intensity, resulting in delayed adjustments, low flexibility, and negatively impacting the user experience.

[0040] In view of the above problems, this application designs a method for controlling the light transmittance of a smart glass. This method acquires the target light intensity (the light intensity of the target road segment where the mobile device is located during a target time period) and the current ambient light intensity (the light intensity of the environment in which the mobile device is located at the current moment). Based on the difference between the two, it determines whether to adjust the light transmittance of the smart glass of the mobile device in advance. This avoids the problem of adjusting the light transmittance of the smart glass only after the ambient light intensity has changed, i.e., after the user has already experienced the adverse effects of the light intensity change (e.g., feeling glare when suddenly entering a bright environment from a dark environment). This achieves flexible control of the light transmittance of the smart glass, improving the user experience.

[0041] In a first aspect, embodiments of this application provide a method for controlling a dimming glass. The method for controlling a dimming glass according to the first aspect of this application will be specifically described below in sections 1.1-1.5.

[0042] 1.1 Overview of the method proposed in this application:

[0043] Referring to Figure 1, which is a flowchart of a method for controlling dimming glass according to an embodiment of this application, the method may include the following steps:

[0044] Step S101: Obtain the target light intensity and the current ambient light intensity. The current ambient light intensity is the light intensity of the environment in which the mobile device is located at the current moment. The target light intensity is the light intensity of the target road segment in which the mobile device is located during the target time period. The target time period is the time period after the current moment.

[0045] Specifically, a mobile device refers to a movable device with transparent glass that can adjust the light transmittance of the glass in real time, such as a vehicle. Current ambient light intensity refers to the light intensity at the location of the mobile device at the current moment, which can be obtained in real time through a light sensor. Target light intensity refers to the light intensity at the location the mobile device is about to reach (i.e., the target road segment). For example, if a vehicle is traveling and (through navigation information) detects that it will enter a tunnel (target road segment) in 5 seconds (target time period), then the target light intensity represents the light intensity inside the tunnel, which can be the average of the light intensities at various locations within the target road segment. This target light intensity can be obtained through navigation information, which may include light intensity information for each road segment at various time periods. Alternatively, the target light intensity can be determined directly based on the type of target road segment. A corresponding target light intensity can be pre-set for each type of target road segment, so that different types of target road segments correspond to different target light intensities. Target road segments can be tunnels, areas without solar shading between buildings, areas shaded by a single tall building, parking lots, or other areas or road segments with significantly different light intensities compared to other areas. The target time period refers to the time it takes for the mobile device to travel to and enter the target road segment at its current speed and under road conditions. The target light intensity can be the light intensity within the target time period, a set of light intensity values, or a specific range of light intensity values.

[0046] Step S102: Based on the difference between the target light intensity and the current ambient light intensity, determine whether to adjust the transmittance of the dimming glass of the mobile device in advance. This advance adjustment means adjusting the transmittance of the dimming glass of the mobile device before it moves to the target road segment. The difference between the target light intensity and the current ambient light intensity can refer to the absolute value of the difference between the two.

[0047] Optionally, if the target light intensity is greater than the current ambient light intensity (the user will move from a darker environment to a brighter environment, and the human eye will find it difficult to adapt to this brightness change, easily feeling dazzled or blinded), then it is determined whether to make advance adjustment; if the target light intensity is less than or equal to the current ambient light intensity (the user will move from a brighter environment to a darker environment, and the human eye can adapt to this brightness change), then it is not determined whether to make advance adjustment, i.e., no advance adjustment is made.

[0048] Step S103: If it is determined that advance adjustment is to be performed, a first instruction is sent to the dimming glass of the mobile device. Specifically, the first instruction indicates that (at the start-up time) the light transmittance of the dimming glass is adjusted to a suitable light transmittance (such as the target light transmittance described below).

[0049] In the automatic dimming mode of mobile devices, the device can automatically adjust its transmittance based on the light intensity information captured by the light sensor, keeping the internal light intensity within a relatively stable range. However, this adjustment scheme (adjusting transmittance solely based on real-time light intensity information) can only adjust the transmittance of the dimming glass after the ambient light intensity changes, resulting in untimely adjustment and low flexibility, which negatively impacts the user experience.

[0050] To address the aforementioned issues, this application proposes a technical solution (i.e., steps S101-S103) that involves making advance adjustments based on the current ambient light intensity (obtained through a light sensor) and the target light intensity (obtained through navigation information).

[0051] In one possible implementation, the mobile device is a vehicle or a portable terminal.

[0052] In this embodiment, the entity executing the above steps (i.e., steps S101-S103) can be an in-vehicle system, and the dimming glass can refer to the dimming glass installed on the windows of the corresponding vehicle. The in-vehicle system sends a first instruction to the dimming glass control module. Specifically, based on the received first instruction, the dimming glass control module controls the light transmittance of the dimming glass by adjusting the magnitude of the current or voltage.

[0053] Specifically, the mobile device obtains navigation information. For example, the mobile device is a vehicle. The user activates the in-vehicle navigation system, or the in-vehicle system obtains navigation data from the mobile terminal. The in-vehicle system then uses the navigation system to obtain information about the target road segments the vehicle will traverse. The navigation information includes the mobile device's route and information about the target road segments it will pass through. For example, the target road segments can be tunnels, bridges, highway checkpoints, or other road segments where the ambient light is lower than in unobstructed areas. They can also be special road segments such as U-turn areas or turning areas. The navigation information may include warnings such as: during a U-turn or turn, the mobile device's dimming glass (or a portion of its dimming glass) will be exposed to strong light. For example, if the vehicle makes a U-turn in road segment A during a target time period, the vehicle's left window will be exposed to strong light in road segment A (i.e., the target road segment in S101), and the light intensity received by the left window in road segment A is 'a' (i.e., the target light intensity in S101). In addition, navigation information may also include spatiotemporal information on light transmittance adjustments manually triggered by other users at the corresponding road segment locations.

[0054] Based on the navigation information obtained, the mobile device determines key nodes or the target road segment to be reached. For example, the vehicle will pass through tunnel A 500 meters ahead (tunnel A is the target road segment), or the vehicle will make a U-turn 200 meters ahead (the U-turn area is the target road segment), or the vehicle will turn left 300 meters ahead (the turning area is the target road segment), etc.

[0055] The mobile device further determines the target light intensity of the upcoming target road segment based on navigation information. The navigation information may also include light intensity information for each road segment at different time periods, including light intensity and direction of illumination. The time of arrival of the mobile device at the target road segment is determined based on the navigation information (i.e., the target time period is determined), thereby determining the target light intensity of the target road segment during the target time period (corresponding to step S101: acquiring the target light intensity). For example, multiple light sensors with different orientations are set on different sides of the dimming glass on the vehicle. Based on the driving route and rules, when making a U-turn in area A, the sunlight that was originally shining directly on the windshield in front of the vehicle will change to shining directly on the left-side window, determining the target light intensity that the left-side window may receive in area A. This embodiment adjusts the light transmittance of the dimming glass in advance based on the acquired target light intensity and the current ambient light intensity, avoiding adverse effects on the user from sudden changes in ambient brightness, thus achieving an anti-glare function.

[0056] This application embodiment acquires the target light intensity and the current ambient light intensity, and determines whether the difference between the two meets preset conditions (e.g., whether the difference exceeds a preset threshold), thereby determining whether to adjust the transmittance of the dimming glass in advance. If advance adjustment is required, a first command is sent to the dimming glass, enabling the mobile device to adjust its transmittance before entering the target road segment. This solves the problem of untimely dimming, achieves flexible control over the transmittance of the dimming glass, and improves the user experience.

[0057] 1.2 Specific methods for determining whether to adjust in advance:

[0058] This embodiment illustrates the specific implementation of step S102. Specifically, this embodiment compares the difference between the target light intensity and the current ambient light intensity with a pre-set first threshold and / or second threshold (for example, if the difference is greater than the first threshold, advance adjustment is performed; or, if the difference is less than the second threshold, no advance adjustment is performed) to determine whether to perform advance adjustment. Furthermore, factors such as the expected passage time of the target road segment, the length of the target road segment, and the duration of historical ambient light intensity below the light intensity threshold are also considered to determine whether to perform advance adjustment, thereby improving the reliability of transmittance control.

[0059] 1.2.1 Consider the estimated transit time or length of the target road segment.

[0060] In one possible implementation, step S102, determining whether to pre-adjust the light transmittance of the dimming glass of the mobile device based on the difference between the target light intensity and the current ambient light intensity, includes:

[0061] Step S1021: If the difference between the target light intensity and the current ambient light intensity is greater than a first threshold, it is determined to perform advance adjustment.

[0062] In one possible implementation, the method further includes:

[0063] Based on the estimated travel time or length of the target road segment, determine whether to adjust the light transmittance of the dimming glass of the mobile device in advance.

[0064] In one possible implementation, determining whether to pre-adjust the light transmittance of the dimming glass of the mobile device based on the estimated travel time or length of the target road segment includes:

[0065] If the difference between the target light intensity and the current ambient light intensity is between a second threshold and a first threshold, it is determined whether to adjust the light transmittance of the dimming glass of the mobile device in advance, based on the expected passage time of the target road segment or the length of the target road segment.

[0066] In addition, step S102 may also include:

[0067] Step S1022: If the difference between the target light intensity and the current ambient light intensity is less than the second threshold, it is determined that no premature adjustment will be performed.

[0068] Step S1023: If the difference between the target light intensity and the current ambient light intensity is between the second threshold and the first threshold, determine whether to adjust the light transmittance of the dimming glass of the mobile device in advance based on the expected passage time of the target road segment or the length of the target road segment.

[0069] In this embodiment, the first threshold is greater than the second threshold. The specific values ​​of the first and second thresholds can be set according to actual needs and are not limited in this embodiment. Referring to Figure 2, which shows a flowchart of determining whether to adjust in advance, if the difference is too small (the difference is less than the second threshold), it means that the light intensity change of the mobile device when it reaches the target road segment is not obvious and no advance adjustment is needed; if the difference is too large (the difference is greater than the first threshold), it means that the light intensity change of the mobile device when it reaches the target road segment is obvious, which may cause the user to be unable to adapt to this light intensity change quickly (the target light intensity is greater than the current ambient light intensity, and the sudden change from a dark environment to a bright environment makes it difficult to open the eyes and feel glare), and advance adjustment is needed to allow the user to adapt to the light intensity change in advance.

[0070] This application proposes that, in addition to determining whether to make advance adjustments, the estimated travel time or length of the target road segment can also be used. Alternatively, for cases where the difference is between a second threshold and a first threshold (including equal to the second threshold or the first threshold), the estimated travel time or length of the target road segment can be used to determine whether to make advance adjustments. The estimated travel time of the target road segment refers to the estimated time required for the mobile device to traverse the target road segment, based on navigation information such as the current mobile device's speed and road conditions. The length of the target road segment can refer to the distance the mobile device needs to travel through the target road segment. The estimated travel time and length of the target road segment can be directly obtained from navigation information.

[0071] It's important to understand that adjusting the transmittance of the dimming glass by a mobile device is not an instantaneous action, especially when the dimming glass is EC dimming glass, which has a slower response time and requires a certain amount of time to complete the transmittance adjustment process. If the estimated travel time of the target road segment is too short, or the target road segment is too short (e.g., a short tunnel), it's easy for the mobile device to move outside the target road segment while the dimming glass is adjusting its transmittance, and the ambient light intensity to change, rendering the adjustment ineffective. To address this issue, this application proposes using the estimated travel time of the target road segment, or the length of the target road segment, as a reference factor to determine whether to perform advance adjustment. This achieves flexible and efficient transmittance adjustment while avoiding ineffective adjustments.

[0072] In one possible implementation, the dimming glass of the mobile device includes at least: electrochromic dimming glass.

[0073] The embodiments of this application determine whether to make advance adjustments based on the difference between the target light intensity and the current ambient light intensity, the estimated passage time of the target road segment, or the length of the target road segment, to avoid frequent light transmittance adjustments to the dimming glass and the occurrence of ineffective adjustments, thereby increasing the service life of the dimming glass.

[0074] In one possible implementation, determining whether to pre-adjust the light transmittance of the dimming glass of the mobile device based on the estimated travel time or length of the target road segment includes:

[0075] If the estimated transit time of the target road segment exceeds a second time threshold, or if the length of the target road segment exceeds a length threshold, it is determined that the light transmittance of the dimming glass of the mobile device should be adjusted in advance.

[0076] If the estimated transit time of the target road segment does not exceed the second time threshold, or if the length of the target road segment does not exceed the length threshold, it is determined that the light transmittance of the dimming glass of the mobile device will not be adjusted in advance.

[0077] The second time threshold can be a preset value or determined based on the difference between the target light intensity and the current ambient light intensity. Specifically, the difference between the target light intensity and the current ambient light intensity is positively correlated with the second time threshold. The larger the difference, the longer the dimming time required, and therefore the larger the second time threshold; conversely, the smaller the difference, the shorter the dimming time required, and therefore the smaller the second time threshold. The second time threshold must be greater than the time required to adjust the dimming glass from its current transmittance to the transmittance suitable for the target light intensity.

[0078] The estimated travel time for a target road segment can be obtained from navigation information or determined in the following ways: based on the navigation information of the user terminal or mobile device, and the speed information of the mobile device (the speed of the mobile device can be the legally mandated maximum speed or the current speed of the mobile device, etc.), the estimated travel time for the target road segment is determined; or, if the target road segment is a U-turn area, the preset U-turn time is determined as the estimated travel time for the target road segment; or, if the target road segment is a turning area, the preset turning time is determined as the estimated travel time for the target road segment.

[0079] Specifically, when the difference between the target light intensity and the current ambient light intensity is between a second threshold and a first threshold, if the estimated travel time of the target road segment is greater than the second time threshold, it is determined that the transmittance of the dimming glass of the mobile device should be adjusted in advance; if the estimated travel time of the target road segment is less than or equal to the second time threshold, it is determined that the transmittance of the dimming glass of the mobile device should not be adjusted in advance. Alternatively, automatic adjustment control can be performed directly based on the length of the target road segment without calculating the estimated travel time. If the length of the target road segment is greater than a length threshold, it is determined that the transmittance of the dimming glass of the mobile device should be adjusted in advance; if the length of the target road segment is less than or equal to the length threshold, it is determined that the transmittance of the dimming glass of the mobile device should not be adjusted in advance. This embodiment determines whether to perform advance adjustment based on whether the estimated travel time of the target road segment is greater than the second time threshold, or whether the length of the target road segment is greater than the length threshold, ensuring that the transmittance adjustment action is completed before the mobile device moves outside the target road segment (i.e., before the ambient light intensity changes again), and avoiding invalid adjustment.

[0080] 1.2.2 also considers a scheme for determining the duration of the current ambient light intensity being lower than the light intensity threshold.

[0081] In one possible implementation, the method further includes:

[0082] Obtain the duration during which the current ambient light intensity is lower than the light intensity threshold;

[0083] Step S102, based on the difference between the target light intensity and the current ambient light intensity, determines whether to pre-adjust the light transmittance of the dimming glass of the mobile device, including:

[0084] Based on the difference between the target light intensity and the current ambient light intensity, and the duration for which the current ambient light intensity is below the light intensity threshold, it is determined whether to adjust the light transmittance of the dimming glass of the mobile device in advance.

[0085] In one possible implementation, determining whether to pre-adjust the light transmittance of the dimming glass of the mobile device based on the difference between the target light intensity and the current ambient light intensity, and the duration for which the current ambient light intensity is below a light intensity threshold, includes:

[0086] Determine whether the duration during which the current ambient light intensity is lower than the light intensity threshold exceeds a first time threshold;

[0087] If the difference between the target light intensity and the current ambient light intensity is greater than a first threshold, and the duration for which the current ambient light intensity is lower than the light intensity threshold does not exceed the first time threshold, it is determined that no early adjustment will be performed.

[0088] If the difference between the target light intensity and the current ambient light intensity is greater than a first threshold, and the duration for which the current ambient light intensity is lower than the light intensity threshold exceeds the first time threshold, it is determined that an advance adjustment will be performed.

[0089] The duration of ambient light intensity below the light intensity threshold refers to the duration during which the mobile device is in a very dark environment (where the ambient light intensity is below the light intensity threshold) before entering the target road segment. If the user stays in the dark environment for too long (exceeding the first time threshold), the human eye may have adapted to the dark environment and become more sensitive to changes in ambient brightness. This duration can be determined based on navigation information. For example, when a vehicle exits a tunnel (where the ambient light intensity is below the light intensity threshold), the duration of travel in this dark environment is defined as the duration. The first time threshold can be set according to actual needs and is not limited in this embodiment.

[0090] In view of the above problems, this application proposes that, when the difference between the target light intensity and the current ambient light intensity is greater than a first threshold: if the duration for which the current ambient light intensity is lower than the light intensity threshold exceeds a first time threshold, then it is determined that early adjustment should be performed; if the duration for which the current ambient light intensity is lower than the light intensity threshold does not exceed the first time threshold, then it is determined that early adjustment should not be performed. When the difference between the target light intensity and the current ambient light intensity is less than a second threshold, it is determined that early adjustment should not be performed.

[0091] If the difference between the target light intensity and the current ambient light intensity is between the second threshold and the first threshold: if the duration for which the current ambient light intensity is lower than the light intensity threshold exceeds the first time threshold, it is determined that advance adjustment should be performed; if the duration for which the current ambient light intensity is lower than the light intensity threshold does not exceed the first time threshold, it is determined that advance adjustment should not be performed.

[0092] In one possible implementation, the method further includes:

[0093] Determine whether the duration during which the current ambient light intensity is lower than the light intensity threshold exceeds a first time threshold;

[0094] If the estimated transit time of the target road segment exceeds the second time threshold, or if the length of the target road segment exceeds the length threshold, and if the duration of the current ambient light intensity being lower than the light intensity threshold does not exceed the first time threshold, it is determined that no advance adjustment will be performed.

[0095] If the estimated travel time of the target road segment exceeds a second time threshold, or if the length of the target road segment exceeds a length threshold, it is determined that the light transmittance of the dimming glass of the mobile device should be adjusted in advance, including:

[0096] If the estimated transit time of the target road segment exceeds the second time threshold, or if the length of the target road segment exceeds the length threshold, and if the duration of the current ambient light intensity being lower than the light intensity threshold exceeds the first time threshold, it is determined to make advance adjustments.

[0097] Specifically, when the difference between the target light intensity and the current ambient light intensity is between the second threshold and the first threshold, if the duration for which the current ambient light intensity is lower than the light intensity threshold does not exceed the first time threshold, it is determined that no advance adjustment will be made (regardless of the expected passage time or length); if the duration for which the current ambient light intensity is lower than the light intensity threshold exceeds the first time threshold, it is determined that advance adjustment will be made (regardless of the expected passage time or length).

[0098] 1.2.3 The case of moving from a bright environment to a dark environment is not considered.

[0099] In one possible implementation, the method further includes:

[0100] If the target light intensity is less than or equal to the current ambient light intensity, it is determined that the transmittance of the dimming glass of the mobile device will not be adjusted in advance.

[0101] Specifically, when the target light intensity equals the current ambient light intensity, the brightness change is not significant and no advance adjustment is required. When the target light intensity is less than the current ambient light intensity, the sudden dimming of the ambient light when the mobile device moves from a bright environment to a dark environment has a relatively small impact on the human eye. To simplify the dimming mechanism, this embodiment proposes that in this case (when the target light intensity is less than the current ambient light intensity), the transmittance of the dimming glass of the mobile device should not be adjusted in advance.

[0102] 1.3 Solution for road sections with very frequent brightness changes:

[0103] This embodiment proposes that in urban scenarios, if tall buildings continuously block sunlight, the brightness will fluctuate frequently. In this case, the above-described scheme (steps S101-S103) is not used to determine whether to adjust in advance. By fully considering various complex and changing application scenarios, the proposed solution provides more flexible control over the light transmittance of the dimming glass.

[0104] In one possible implementation, before acquiring the target light intensity and the current ambient light intensity, the method further includes:

[0105] Determine whether the type of the environment in which the mobile device is located at the current moment belongs to the target type. An environment that belongs to the target type satisfies the following conditions: the amplitude of light intensity change is greater than the amplitude threshold and the frequency of light intensity change is greater than the frequency threshold.

[0106] If the type belongs to the target type, no first instruction is sent to the dimming glass of the mobile device before the mobile device moves outside the target road segment; or,

[0107] If the type belongs to the target type, the target light intensity and the current ambient light intensity are not acquired; or,

[0108] If the type belongs to the target type, the step of determining whether to pre-adjust the light transmittance of the dimming glass of the mobile device is not performed;

[0109] Step S101, acquire the target light intensity and the current ambient light intensity, including:

[0110] If the type does not belong to the target type, obtain the target light intensity and the current ambient light intensity.

[0111] Optionally, determining whether the type of the environment in which the mobile device is currently located belongs to the target type includes:

[0112] Acquire historical light intensity change information of the environment, including: the magnitude and frequency of light intensity change of the environment during the historical time period before the current moment;

[0113] Based on the historical light intensity change information of the environment, determine whether the type of environment in which the mobile device is located at the current moment belongs to the target type.

[0114] The type of environment in which the mobile device is located at the current moment (i.e., the area where the mobile device is currently located) is determined. Based on navigation information, the types of various areas (or road segments) can be classified as: urban road type, rural road type, mountain road type, etc. (including the target type). Specifically, historical light intensity change information of the environment (referring to the environment in which the mobile device is located at the current moment) can be obtained first. This includes the amplitude of light intensity change (i.e., the range of light intensity change) and the frequency of light intensity change within this environment. For example, the ambient light sensor on the vehicle captures ambient light change information in real time. For instance, the ambient light sensor located at the window captures the light intensity shining on the window and generates historical ambient light change information (i.e., historical light intensity change information). In this environment, the light intensity changes from a maximum value A to a minimum value B every 5 seconds (light intensity change frequency), and then from a minimum value B to a maximum value A (light intensity change amplitude). Then, if the amplitude of light intensity change is too large (the amplitude of light intensity change is greater than a preset amplitude threshold), making the light intensity change too obvious, and the light intensity change is too frequent (the frequency of light intensity change is greater than a preset frequency threshold), then the environment is determined to belong to the target type. In this case, no adjustments are made before entering the target road segment, and after entering the target road segment, the dimming glass is controlled not to respond to ambient light in real time and the light transmittance is not adjusted until the mobile device moves outside the target road segment.

[0115] In scenarios where transmittance is automatically adjusted, when the environment is of a target type and the ambient light intensity within the target road segment changes frequently, the transmittance may not have reached the target transmittance (the current transmittance adjustment is not yet complete) before the ambient light changes again, resulting in ineffective adjustment. Furthermore, excessive ineffective adjustments can damage the dimming glass. To address these issues, this embodiment proposes that when the mobile device is about to pass through such a target-type environment (where tall buildings continuously block sunlight, causing frequent changes in ambient light intensity), no pre-adjustment is performed. Moreover, the dimming glass is controlled not to respond to ambient light in real time, thereby avoiding ineffective adjustment and further improving the control flexibility of the dimming glass.

[0116] 1.4 Specific plans for implementing advance adjustments:

[0117] This embodiment provides a detailed description of step S103. Referring to Figure 3, which shows a flowchart of a transmittance pre-adjustment process, as shown in Figure 3, when it is determined that pre-adjustment is required, this embodiment proposes to further determine the target transmittance (the transmittance that the dimming glass can achieve through adjustment) and the start time (the moment when the transmittance of the dimming glass changes). The first command is then sent at the start time to adjust the transmittance of the dimming glass to the target transmittance, further refining the pre-adjustment execution method and avoiding adverse effects on the mobile device in the current driving area, thereby improving control flexibility.

[0118] In one possible implementation, upon determining that advance adjustment is to be performed, a first instruction is sent to the dimming glass of the mobile device, including:

[0119] A first instruction is sent to the dimming glass of the mobile device, the first instruction being used to instruct the light transmittance of the dimming glass to be adjusted to a target light transmittance.

[0120] In this process, after determining that advance adjustment is needed, a first instruction is sent to the dimming glass (which may be a dimming glass control module) to control the dimming glass and adjust its transmittance to the target transmittance. For example, the mobile device can be a vehicle. Referring to Figure 4, which shows a flowchart of an automatic adjustment scheme, the dimming glass also includes a dimming glass control module, which receives instructions and adjusts the transmittance of the dimming glass. The overall process is as follows:

[0121] Step 1: The vehicle system receives registration requests from the vehicle-mounted light sensor and the dimming glass control module.

[0122] Step 2: The vehicle system receives the user's input command to activate automatic dimming mode. Specifically, the automatic dimming command can be a standard command containing a target ambient light intensity range, ensuring the vehicle's interior light intensity remains within that range during automatic dimming. Alternatively, it can be a preset transmittance based on captured external ambient light, or the user can manually set a transmittance before entering automatic dimming mode. Further automatic dimming commands can be user-selected special scene modes, such as sun protection mode, anti-glare mode, reading mode, or movie viewing mode.

[0123] Step 3: The vehicle system executes steps S101-S103 in Section 1.1 to acquire information collected by the vehicle's light sensor (current ambient light intensity) and navigation information, etc., to determine whether to perform advance adjustment. If it is determined that advance adjustment is to be performed, a first command is sent to the dimming glass control module of the vehicle's dimming glass (equivalent to sending a first command to the dimming glass).

[0124] Step 4: The dimming glass control module responds to the first command and adjusts the light transmittance of the vehicle's dimming glass to the target light transmittance.

[0125] 1.4.1. Specific methods for determining the target transmittance.

[0126] In one possible implementation, the target transmittance is determined by the following steps:

[0127] Based on the target road segment, the pre-stored correspondence between different environment types and light transmittance is queried to determine the target light transmittance; or

[0128] The target transmittance is determined based on the target light intensity.

[0129] In this embodiment, the target transmittance can be pre-set by pre-storing transmittance corresponding to different scenarios (environments). For example, a tunnel environment might correspond to a transmittance A, and an underground parking lot environment might correspond to a transmittance B, etc. Then, by using navigation information (i.e., querying the pre-stored correspondence between different environment types and transmittance), the type of the target road segment (i.e., the environment type) is determined, and thus the corresponding target transmittance is determined. The target transmittance can be obtained through interpolation or by looking up a table. Alternatively, the correspondence between target light intensity and transmittance can be pre-stored, and then the corresponding target transmittance can be determined directly based on the magnitude of the target light intensity.

[0130] In addition, the first ambient light intensity and the second ambient light intensity of the target road segment can be determined, and if the number of switching between the first ambient light intensity and the second ambient light intensity reaches a first switching number threshold, the target transmittance can be determined based on the first ambient light intensity and the second ambient light intensity.

[0131] There may also be situations where the light intensity within the target road segment is unstable. For example, the light intensity of the target road segment may frequently switch between the first and second ambient light intensities. For instance, if the target road segment is an urban road with constant building obstruction, the number of times the light intensity switches between the first and second ambient light intensities may reach a first switching threshold. In this case, the first and second ambient light intensities of the target road segment can be determined based on navigation information or historical light intensity change information; these are the maximum and minimum values ​​of the light intensity variation. The transmittance corresponding to the median value of the first and second ambient light intensities can be taken as the target transmittance. This reduces the impact of frequent light intensity changes and helps maintain the brightness of the switching glass in a relatively stable state.

[0132] In one possible implementation, the method further includes:

[0133] Determine the estimated travel time of the mobile device on the target road segment within the target time period;

[0134] The target transmittance is determined according to the following steps:

[0135] Based on the target road segment, the pre-stored correspondence between different environment types and light transmittance is queried, and the target light transmittance is determined in conjunction with the estimated passage time.

[0136] This embodiment proposes that, when determining the target transmittance, the estimated travel time of the mobile device through the target road segment should also be considered. The estimated travel time is combined with the light intensity information of the target road segment. The target transmittance is positively correlated with the estimated travel time; if the estimated travel time is longer, a larger target transmittance is selected; if the estimated travel time is shorter, a smaller target transmittance is selected. The target transmittance is positively correlated with the estimated travel time.

[0137] When the light intensity of the target road segment frequently switches between the first ambient light intensity and the second ambient light intensity, the target transmittance can also be determined in the following way: determine the first ambient light intensity and the second ambient light intensity of the target road segment; when the number of switching between the first ambient light intensity and the second ambient light intensity reaches the switching number threshold, determine the target transmittance based on the first ambient light intensity and the second ambient light intensity, combined with the expected passage time.

[0138] 1.4.2 Determine the start time.

[0139] In one possible implementation, upon determining that advance adjustment is to be performed, a first instruction is sent to the dimming glass of the mobile device, including:

[0140] If advance adjustments are determined, the estimated arrival time of the mobile device at the target road segment is as follows;

[0141] Based on the arrival time, determine the start time for adjusting the transmittance of the dimming glass;

[0142] At the startup time, a first command is sent to the dimming glass of the mobile device.

[0143] This embodiment proposes that when sending the first command, the start time needs to be determined, and the light transmittance is adjusted only after the start time is reached. Specifically, the time when the mobile device reaches the entrance position of the target road segment (arrival time) is first estimated, and then the start time is determined based on the arrival time. This start time refers to the time when the first adjustment command is sent to the dimming glass of the mobile device, that is, the time when the dimming operation is performed on the dimming glass.

[0144] In one possible implementation, determining the start time for adjusting the transmittance of the dimming glass based on the arrival time includes:

[0145] The start time is determined based on the preset time difference and the arrival time; or

[0146] The start time is determined based on the transmittance adjustment amount and the arrival time. The difference between the start time and the arrival time is positively correlated with the transmittance adjustment amount, which is the difference between the target transmittance and the current transmittance of the dimming glass.

[0147] In automatic dimming mode, the light transmittance of the dimming glass corresponds to the ambient light intensity; that is, the light transmittance of the dimming glass varies under different ambient light intensities. The current light transmittance of the dimming glass refers to the real-time light transmittance of the mobile device's dimming glass at the current moment, which corresponds to the light intensity of the current environment in which the mobile device is located.

[0148] This embodiment proposes two methods for determining the start time: One method is to pre-set a fixed value (i.e., a preset time difference) between the arrival time and the start time, such as 1 second or 2 seconds. For example, if the estimated arrival time of the mobile device is 1 minute and 10 seconds, and the preset time difference is 1 second, then at 1 minute and 9 seconds (the start time), the first command is sent to the dimming glass of the mobile device to control the dimming glass to perform the dimming operation. The other method is to calculate the difference between the arrival time and the start time based on the transmittance adjustment amount. The transmittance adjustment amount refers to the difference between the current transmittance of the dimming glass and the target transmittance. The difference between the arrival time and the start time is positively correlated with the transmittance adjustment amount; the larger the transmittance adjustment amount, the longer the dimming time needs to be reserved, and the larger the difference; the smaller the transmittance adjustment amount, the shorter the dimming time needs to be reserved, and the smaller the difference. This embodiment further refines the execution method of advance adjustment by determining the start time of advance adjustment, avoiding adverse effects of advance adjustment on the mobile device in the current driving area, and improving the flexibility of control.

[0149] 1.5 Two-stage adjustment method:

[0150] This embodiment proposes a two-stage adjustment method when advance adjustment is determined. Specifically, in the first stage, as the target road segment approaches, a first command is used to adjust the light transmittance of the dimming glass to a first target light transmittance. In the second stage, after entering the target road segment, a second command is used to adjust the light transmittance of the dimming glass to a second target light transmittance. This two-stage adjustment method makes the light transmittance change of the dimming glass more gradual and stable, avoiding sudden brightness changes that could affect the user experience and further improving the control flexibility of the dimming glass.

[0151] In one possible implementation, upon determining that advance adjustment is to be performed, a first instruction is sent to the dimming glass of the mobile device, including:

[0152] Send a first command to the dimming glass of the mobile device;

[0153] In response to the first instruction, the light transmittance of the dimming glass of the mobile device is adjusted to a first target light transmittance;

[0154] The method further includes:

[0155] After the mobile device arrives at the target road segment, the transmittance of the second target is determined based on the actual light intensity of the target road segment.

[0156] Send a second command to the dimming glass of the mobile device;

[0157] In response to the second instruction, the light transmittance of the dimming glass of the mobile device is adjusted to the second target light transmittance.

[0158] Specifically, in the first stage, i.e. the pre-adjustment stage, when the mobile device arrives at the target road segment or at the start time determined in Section 1.4, a first command is sent to the dimming glass of the mobile device; the dimming glass responds to the first command and adjusts the light transmittance of the dimming glass of the mobile device to a first target light transmittance, which is located between the first light transmittance corresponding to the current ambient light intensity and the second light transmittance corresponding to the target light intensity.

[0159] In the second stage, after the mobile device enters the target road segment, the ambient light intensity of the target road segment in real time is collected, the transmittance corresponding to the ambient light intensity of the target road segment in real time is determined (i.e., the second target transmittance), and a second command is sent to the dimming glass of the mobile device, so that the dimming glass responds to the second command and adjusts the transmittance of the dimming glass of the mobile device to the second target transmittance.

[0160] In this embodiment, when the ambient light intensity is less than the target light intensity (when transitioning from a dark environment to a bright environment), the transmittance of the second target is greater than that of the first target; when the ambient light intensity is greater than the target light intensity (when transitioning from a bright environment to a dark environment), the transmittance of the second target is less than that of the first target. The transmittance of the second target can be calculated using linear interpolation or a mapping table.

[0161] In one possible implementation, the first target transmittance is determined according to the following steps:

[0162] The transmittance of the first target is determined based on the current ambient light intensity and the target light intensity.

[0163] In one possible implementation, determining the first target transmittance based on the current ambient light intensity and the target light intensity includes:

[0164] The intermediate light intensity is determined based on the current ambient light intensity and the target light intensity.

[0165] The transmittance of the first target is determined based on the intermediate light intensity.

[0166] In one possible implementation, determining the first target transmittance based on the current ambient light intensity and the target light intensity includes:

[0167] Based on the current ambient light intensity, determine the first transmittance corresponding to the current ambient light intensity;

[0168] Based on the target light intensity, determine the second transmittance corresponding to the target light intensity;

[0169] Based on the first transmittance and the second transmittance, the first target transmittance is determined, and the first target transmittance is located between the first transmittance and the second transmittance.

[0170] Specifically, the midpoint between the first transmittance and the second transmittance can be taken as the first target transmittance, so that the first target transmittance takes into account both ambient light (current ambient light intensity and target light intensity) and will not cause strong discomfort under either ambient light.

[0171] 1.6. Plan after entering the target road section.

[0172] After the mobile device has entered the target road segment, there may be a lack of prior adjustments, resulting in the current light transmittance of the dimming glass being incompatible with the ambient light intensity of the target road segment. This embodiment proposes to re-determine whether to adjust the light transmittance based on the remaining transit time of the mobile device after it has moved outside the target road segment. This avoids ineffective adjustments due to the mobile device having already moved outside the target road segment during the adjustment process, further improving the control flexibility of the dimming glass.

[0173] In one possible implementation, after the mobile device has entered the target road segment, the method further includes:

[0174] The estimated remaining transit time for the mobile device to move outside the target road segment;

[0175] If the remaining transmission time is greater than the adjustment threshold time, it is determined that the light transmittance of the dimming glass of the mobile device shall be adjusted.

[0176] Send a second command to the dimming glass of the mobile device;

[0177] In response to the second instruction, the light transmittance of the dimming glass of the mobile device is adjusted to the second target light transmittance.

[0178] Specifically, the remaining travel time refers to the time required for a mobile device to move from its current location to the destination road segment. The remaining travel time can be determined based on navigation information (including the length of the remaining road segment, road conditions, and the current speed of the mobile device) or an image sensor. Specifically, an image sensor can acquire environmental image information about the mobile device's surroundings to identify the current scene (target road segment), such as tunnels, bridges, tree-lined roads, highway checkpoints, etc., and may also include situations like turns and U-turns. The image sensor can also acquire distance information (the distance between the mobile device and the destination of the target road segment). The remaining travel time is then calculated using distance and speed. The adjustment threshold time represents the maximum time required for the dimming glass to adjust its light transmittance.

[0179] If the remaining passage time is greater than the adjustment threshold time, it means that the transmittance adjustment can be completed before the mobile device moves outside the target road segment, and no invalid adjustment will occur. If the remaining passage time is less than or equal to the adjustment threshold time, it means that the transmittance adjustment cannot be completed before the mobile device moves outside the target road segment, and invalid adjustment is likely to occur.

[0180] In one possible implementation, after the mobile device has entered the target road segment, the method further includes:

[0181] The first light intensity and the second light intensity of the mobile device in the target road segment are determined. When the number of switching between the first light intensity and the second light intensity reaches a second switching number threshold, the desired light transmittance is determined based on the first light intensity and the second light intensity.

[0182] Send a second command to the dimming glass of the mobile device;

[0183] In response to the second instruction, the light transmittance of the dimming glass of the mobile device is adjusted to the second target light transmittance.

[0184] Specifically, when the target road segment is in an environment with constantly alternating light and dark conditions, the ambient light intensity frequently switches between a first light intensity and a second light intensity. The first and second light intensities of the target road segment can be determined based on navigation information, historical light intensity change information, or historical light intensity information collected by the light sensor on the mobile device—that is, the maximum and minimum values ​​within the light intensity variation range. Referring to Figure 5, which illustrates a flowchart of determining whether to adjust transmittance based on the number of switching cycles, if the number of switching cycles between the first and second light intensities reaches a second switching threshold, the transmittance corresponding to the midpoint between the first and second light intensities can be taken as the second target transmittance. By adjusting the transmittance to the second target transmittance, the impact of frequent light intensity changes is reduced, and the brightness of the dimming glass is maintained in a relatively stable state as much as possible.

[0185] In one possible implementation, the method further includes:

[0186] If the actual transit time of the target road segment exceeds the expected transit time of the target road segment, the system determines whether to adjust the light transmittance of the dimming glass of the mobile device at the current moment based on the current navigation traffic information.

[0187] Specifically, in practical applications, road conditions are complex and varied, including traffic jams, which can cause the actual time taken for a mobile device to traverse a target road segment to exceed the pre-calculated estimated travel time. This embodiment proposes that when the estimated travel time has been reached, and the mobile device has not yet moved beyond the target road segment, it is necessary to re-determine whether to adjust the light transmittance of the dimming glass in real time based on the current navigation traffic information, thereby further improving the flexibility of light transmittance adjustment.

[0188] 1.7 Methods for determining target light intensity:

[0189] In one possible implementation, the method further includes:

[0190] The type of the target road segment is determined based on the navigation information of the mobile device;

[0191] The target light intensity is determined based on the type of the target road segment.

[0192] Specifically, the target light intensity can be determined directly based on the type of the target road segment. A corresponding target light intensity can be pre-set for each type of target road segment, ensuring that different road segment types correspond to different target light intensities. Target road segment types can include tunnels, unshaded areas between buildings, areas shaded by a single tall building, parking lots, and other areas or road segments with significantly different light intensities compared to other areas. Based on the mobile device's navigation information, the type of the target road segment the mobile device is about to enter can be determined, thus establishing the corresponding target light intensity.

[0193] In one possible implementation, the method further includes:

[0194] The ambient light intensity is acquired by multiple optical sensors of the mobile device, and the multiple optical sensors are distributed at different locations of the mobile device;

[0195] Based on the estimated movement path of the mobile device and the positions of the plurality of optical sensors on the mobile device, the light intensity collected by the target optical sensor among the plurality of optical sensors is determined as the target light intensity.

[0196] Specifically, mobile devices can be equipped with multiple light sensors in different positions and orientations to collect light intensities from multiple directions when the device changes direction. For example, on a vehicle, multiple light sensors with different orientations are installed on different sides of the dimming glass. Based on the mobile device's estimated movement path, when it makes a U-turn in area A, the sunlight that was originally shining directly on the windshield will now shine directly on the left-side window. This determines the target light intensity that the left-side window (target light sensor) might receive in area A. The light intensity collected by the left-side window (target light sensor) is then defined as the target light intensity.

[0197] In one possible implementation, the method further includes:

[0198] Acquire a reference ambient light intensity from a reference mobile device, wherein the reference ambient light intensity is the light intensity collected by the light sensor of the reference mobile device while passing through the target road segment;

[0199] The reference ambient light intensity is determined as the target light intensity.

[0200] Specifically, the reference mobile device (e.g., other vehicles) collects real-time ambient light intensity at various locations during its movement. For example, when passing through target road segment A, the ambient light intensity at target road segment A is collected and stored as reference ambient light intensity to assist the mobile device in determining the target light intensity corresponding to the target road segment. Furthermore, among the ambient light intensities collected by the reference mobile device, those meeting a first condition (e.g., the time threshold for the reference mobile device to pass through the target road segment is within the expected passage time) are stored as reference ambient light intensity. The first condition indicates that the reference mobile device is in a normal moving state. Ambient light intensities that do not meet the first condition are deleted as error information.

[0201] A second aspect of this application also provides a method for controlling a dimming glass, the method comprising:

[0202] Determine the estimated transit time for the first target area where the mobile device is located;

[0203] Determine whether the estimated transit time exceeds the third time threshold;

[0204] If the expected transit time exceeds the third time threshold, the light transmittance of the dimming glass of the mobile device is adjusted.

[0205] If the expected transit time does not exceed the third time threshold, the light transmittance of the dimming glass of the mobile device will not be adjusted.

[0206] The adjustment of light transmittance by a mobile device on a dimming glass is not an instantaneous action, especially when the dimming glass is an EC dimming glass, which has a slow response speed and requires a certain amount of time to complete the light transmittance adjustment process. If the estimated passage time to the first target area is too short (e.g., a short tunnel, where the estimated passage time does not exceed a third time threshold), it is easy for the mobile device to move outside the first target area and the ambient light intensity to change during the light transmittance adjustment process, rendering the adjustment ineffective. To solve the above problem, this application proposes to use the estimated passage time to the first target area as a reference factor to determine whether to perform light transmittance adjustment, thereby achieving flexible and efficient light transmittance adjustment while avoiding ineffective adjustment.

[0207] In one possible implementation, the method further includes:

[0208] The target time threshold is determined as the third time threshold; or

[0209] The third time threshold is determined based on the transmittance adjustment amount. The third time threshold is positively correlated with the transmittance adjustment amount, which is the difference between the target transmittance and the current transmittance of the dimming glass.

[0210] Specifically, this embodiment determines the third time threshold based on the transmittance adjustment amount. The transmittance adjustment amount refers to the difference (which can be an absolute value) between the current real-time transmittance of the dimming glass and the target transmittance. The third time threshold is positively correlated with the transmittance adjustment amount; a larger transmittance adjustment amount requires a longer dimming time, resulting in a larger third time threshold; conversely, a smaller transmittance adjustment amount requires a shorter dimming time, resulting in a smaller third time threshold. This embodiment achieves dynamic determination of the third time threshold by determining the transmittance adjustment amount, thereby improving the flexibility of control.

[0211] The third aspect also provides another method for controlling dimming glass, the method comprising:

[0212] Determine the first ambient light intensity and the second ambient light intensity of the second target area where the mobile device is located;

[0213] The transmittance of the third target is determined based on the first ambient light intensity and the second ambient light intensity.

[0214] The dimming glass of the mobile device sends a transmittance adjustment command, which instructs the transmittance of the dimming glass to be adjusted to the third target transmittance.

[0215] In one possible implementation, determining the transmittance of the third target based on the first ambient light intensity and the second ambient light intensity includes:

[0216] Based on the first ambient light intensity, determine the first transmittance corresponding to the first ambient light intensity;

[0217] Based on the second ambient light intensity, determine the second transmittance corresponding to the first ambient light intensity;

[0218] The third target transmittance is determined based on the first transmittance and the second transmittance, and the third target transmittance is located between the first transmittance and the second transmittance.

[0219] Specifically, the midpoint between the first and second transmittance can be taken as the third target transmittance, so that the third target transmittance takes into account both ambient lights and does not cause strong discomfort when the two ambient lights switch frequently.

[0220] In one possible implementation, the method further includes:

[0221] Determine whether the type of the environment in which the mobile device is located belongs to the target type. An environment that belongs to the target type satisfies the following conditions: the light intensity change amplitude is greater than the amplitude threshold and the light intensity change frequency is greater than the frequency threshold. The light intensity change amplitude is the difference between the light intensities of at least two different environments in which the mobile device is located, and the light intensity change frequency is the switching frequency between the light intensities of at least two different environments in which the mobile device is located.

[0222] If the type of environment in which the mobile device is located belongs to the target type, the area where the mobile device is located is determined as the second target area.

[0223] Specifically, the system first acquires information about the ambient light intensity changes in the environment in which the mobile device is located at the current moment. This includes the amplitude (range) and frequency of light intensity changes within this environment. If the amplitude of light intensity changes is too large (greater than a preset amplitude threshold), making the changes too obvious, and if the frequency of light intensity changes is too frequent (greater than a preset frequency threshold), then the environment is determined to be a target type, i.e., the area where the mobile device is located is designated as the second target area.
