[0106] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0107] During long-term use, the dimming function of the film will gradually degrade due to the influence of electric fields, environmental factors, etc., affecting the service life of the film. Therefore, it is crucial to effectively monitor the life of the film.

[0108] In related technologies, the lifespan of a film can be measured in advance through methods such as power-on / power-off cycling tests and aging tests. However, since these tests are conducted in laboratories, they can only provide a general and general estimate of the film's lifespan, making real-time, online monitoring difficult. Furthermore, due to varying user habits and environments, frequent dimming operations on the film, and prolonged use at high temperatures can significantly reduce the film's lifespan. This means that the lifespan of the film obtained through laboratory testing is inaccurate.

[0109] Reference Figure 1 , Figure 1 FIG. 1 is a flow chart showing a method for monitoring the life of a dimming film according to an exemplary embodiment. Figure 1 As shown, the life monitoring method of the dimming film includes the following steps.

[0110] In step S101 , operation data of the switchable film during use is acquired, wherein the operation data includes charge capacity data of the switchable film at a dimming gear.

[0111] In step S102, the operating data is sent to a cloud, so that the cloud can monitor the lifespan attenuation of the dimming film according to the operating data.

[0112] For example, a dimming film is an electronic light control product that can be commonly used in building curtain walls, car skylights, and aircraft windows, etc. It can also be applied to displays or other devices, equipment, structures or buildings that require privacy protection.

[0113] Among them, the life monitoring of the dimming film on the car can be used for the dimming film on the front and rear windshields, windows, triangular windows, front and rear partitions, skylights and other glass.

[0114] For example, the dimming film can cause the material to undergo an oxidation-reduction reaction by applying an electric current to change the color, switch between transparent and opaque states, and adjust the degree of opacity, etc., which can achieve the purposes of sun protection or privacy protection.

[0115] For example, the dimming film can have multiple dimming gears when controlled, and different dimming gears can correspond to different dimming transparencies and / or different dimming gears can correspond to different colors. The dimming film can be controlled by a dimming controller corresponding to the dimming film.

[0116] For example, in a vehicle, a gear adjustment signal can be sent to a dimming controller through a vehicle controller, such as a TBOX (Telematics BOX, telematics control unit), an intelligent driving domain controller, a gateway controller, a cockpit domain controller, other domain controllers, etc., so that the dimming controller can adjust the transparency or color of the dimming film according to the dimming gear included in the gear adjustment signal.

[0117] For example, the life monitoring method of the dimming film disclosed in the present invention can be applied to vehicle controllers, such as TBOX (Telematics BOX, remote information processing control unit), intelligent driving domain controller, gateway controller, cockpit domain controller, other domain controllers, etc. It can be applied to controllers in transportation vehicles such as airplanes and high-speed railways equipped with dimming films, and can also be directly applied to dimming controllers of dimming films.

[0118] For example, charge capacity data is the amount of charge stored per unit area in the dimming mode of the dimming film. Charge capacity data can be used to quantify the dimming performance of the film, and its variation is closely related to the lifespan of the film. Charge capacity can be correlated with the transparency or color of the film. For example, for the same dimming film, there is a negative correlation between charge capacity and transparency: the greater the charge capacity, the lower the transparency. For example, different charge capacity values ​​correspond to different colors.

[0119] For example, charge capacity data can be further obtained by obtaining current data, voltage data, and time parameters of the dimming film at the current dimming level. For example, the charge capacity data may include the actual charge capacity and theoretical charge capacity of the dimming film. Different dimming levels correspond to different theoretical charge capacities.

[0120] The actual charge capacity of the charge and discharge can be obtained by integrating the current data with a time parameter, or by directly measuring the actual charge capacity of the dimming film using an instrument or other method. The theoretical charge capacity corresponding to the dimming position can be determined using the acquired voltage data and the corresponding relationship between voltage and theoretical charge capacity, or based on the current dimming position feedback from the vehicle controller and the corresponding relationship between the dimming position and theoretical charge capacity.

[0121] For example, the operational data of the switchable film during use may include the charge capacity data of the switchable film in the dimming mode, and may also include other operational data that may have an impact on the service life of the switchable film. For example, the operational data may also include user operation frequency data, the frequency of invalid consecutive clicks by the user, the environment data of the object equipped with the switchable film, geographic location data, the material used by the switchable film, etc.

[0122] For example, the cloud can provide computing resources and services that can be used for data storage, processing, and analysis. In particular, the cloud can monitor the lifespan degradation of the dimming film based on the operating data.

[0123] For example, during the use of the film, operational data can be collected in real time. The cloud can analyze this data using pre-set algorithms or models to monitor the film's lifespan degradation. Furthermore, the cloud can also establish a characteristic model for the film's lifespan degradation through long-term data accumulation and analysis, enabling accurate lifespan prediction.

[0124] The present disclosure transmits operational data of the dimming film during use to the cloud, which is then used by the cloud to monitor the lifespan degradation of the dimming film based on the operational data. The operational data includes charge capacity data of the dimming film in the dimming mode. By transmitting operational data such as charge capacity data to the cloud, real-time and remote monitoring of the lifespan of the dimming film can be achieved, allowing for timely detection of potential failure points of the dimming function and providing data support for the design and improvement of the dimming film.

[0125] As an optional embodiment, the charge capacity data includes theoretical charge capacity and actual charge capacity;

[0126] The monitoring of the lifespan attenuation of the dimming film according to the operating data includes:

[0127] determining a difference between the actual charge capacity and the theoretical charge capacity;

[0128] The life attenuation of the dimming film is determined according to the numerical relationship between the difference and the set value.

[0129] For example, the theoretical charge capacity is the amount of charge that the dimming film can theoretically store / release when charging and discharging at that dimming setting. The actual charge capacity is the amount of charge that the dimming film can actually store / release when charging and discharging at that dimming setting. Typically, the actual charge capacity is less than or equal to the theoretical charge capacity.

[0130] For example, the difference between the actual charge capacity and the theoretical charge capacity is the numerical difference between the actual charge capacity and the theoretical charge capacity, which can be used to reflect the degradation of the performance of the dimming film. The set value can be a pre-set reference value for judging the degree of degradation of the dimming film life, which is usually determined based on experiments or experience, such as 5mAh or 0mAh.

[0131] For example, the difference between the actual charge capacity and the theoretical charge capacity can be determined based on the difference between the actual charge capacity and the theoretical charge capacity, and the difference can be used to reflect changes in the performance of the dimming film. Different environments, different geographical locations, and different user operations may lead to differences between the actual charge capacity and the theoretical charge capacity. That is, the actual charge capacity may fluctuate based on the environment, geographical location, and user operating habits of the dimming film. By setting a set value, the performance life degradation of the dimming film can be characterized based on the numerical relationship between the difference and the set value.

[0132] For example, the life attenuation condition can represent whether the life of the switchable film is greatly attenuated, slightly attenuated, attenuated or not attenuated, etc. The set value can be set or calibrated according to actual design requirements.

[0133] For example, when the life decay condition is set to indicate whether the life of the dimming film has decayed or not decayed, the set value can be set to one, such as 5mAh. When the difference between the actual charge capacity and the theoretical charge capacity is greater than 5mAh, the life decay condition can indicate that the life of the dimming film has decayed; when the difference between the actual charge capacity and the theoretical charge capacity is less than or equal to 5mAh, the life decay condition can indicate that the life of the dimming film has not decayed.

[0134] For example, when the life decay situation is set to be used to characterize the degree of life decay of the dimming film as large, small or no decay, the set value can be set to two, such as 2mAh and 6mAh. Among them, when the difference between the actual charge capacity and the theoretical charge capacity is greater than 6mAh, the life decay situation can characterize the degree of life decay of the dimming film as large; when the difference between the actual charge capacity and the theoretical charge capacity is less than or equal to 6mAh and greater than 2mAh, the life decay situation can characterize the degree of life decay of the dimming film as small; when the difference between the actual charge capacity and the theoretical charge capacity is less than or equal to 2mAh, the life decay situation can characterize the degree of life decay of the dimming film as no decay.

[0135] The present invention determines the life attenuation of the dimming film through the numerical relationship between the difference between the theoretical charge capacity and the actual charge capacity and the set value, and can issue an early warning to remind the user to perform maintenance or replacement, thereby ensuring the normal use of the dimming film and improving the user experience.

[0136] As an optional embodiment, the method further includes:

[0137] Receive an update strategy for the dimming gear sent by the cloud, where the update strategy is output by the cloud at least based on the life attenuation condition.

[0138] For example, the update strategy is an optimization solution generated by the cloud for the dimming gear according to the life attenuation of the dimming film. The dimming gear of the dimming film can be adjusted through the update strategy to extend its service life or improve its performance.

[0139] For example, in a vehicle, the cloud can push a notification message to the vehicle. The vehicle receives the update policy for the dimming gear sent by the cloud and can remind the user to recalibrate the dimming gear at the car after-sales service center through the vehicle screen or voice prompts. Alternatively, the cloud can push a notification message to the vehicle. Once the user confirms that the update is possible, the cloud sends a system upgrade package to the vehicle via Over The Air (OTA) technology, which allows the vehicle to update the dimming gear based on the system upgrade package.

[0140] For example, the cloud can determine the lifespan degradation of the dimming film based on the difference between the actual charge capacity and the theoretical charge capacity, and generate an optimization plan for updating the dimming gear based on the lifespan degradation. The cloud can also analyze the factors that may be related to the lifespan degradation of the dimming film using the received operating data, and output a strategy for updating the dimming gear based on the factors that may be related to the lifespan degradation.

[0141] As an optional embodiment, the receiving the update policy sent by the cloud includes:

[0142] Receive a first update strategy sent by the cloud, where the first update strategy is output by the cloud in response to the lifespan decay condition indicating that the difference exceeds a first set value, and the first update strategy is used to reduce the theoretical charge capacity corresponding to the dimming gear.

[0143] For example, the first update strategy is an optimization solution directly generated by the cloud when the difference between the actual charge capacity and the theoretical charge capacity of the dimming film exceeds a first set value, which can be used to reduce the theoretical charge capacity corresponding to the dimming gear of the dimming film.

[0144] For example, the first set value is a pre-set reference value that can be set according to actual conditions. The first set value can be used to determine whether the life of the dimming film has decreased to a level that requires an update strategy. For example, the first set value can be 5mAh, 8mAh, etc.

[0145] For example, the cloud can calculate the difference between the theoretical charge capacity and the actual charge capacity based on the operating data of the dimming film and analyze whether the difference exceeds a first set value. If the difference exceeds the first set value, the cloud generates a first update strategy and sends it to the device controller corresponding to the dimming film, instructing the controller to reduce the theoretical charge capacity corresponding to the dimming level according to the first update strategy.

[0146] The present disclosure reduces the theoretical charge capacity corresponding to the dimming gear, thereby reducing the number of overcharge and overdischarge and the charge capacity of the dimming film, that is, reducing the operating time of the dimming film under high load conditions, thereby extending the service life of the dimming film, while having little impact on the performance of the dimming film.

[0147] As an optional embodiment, the operation data further includes environmental data when the switchable film is used;

[0148] The receiving the update strategy sent by the cloud includes:

[0149] Receive a second update strategy sent by the cloud, where the second update strategy is output by the cloud in response to the life decay condition characterizing that the difference exceeds a first set value based on the environmental data, and the second update strategy is used to set the theoretical charge capacity corresponding to the dimming gear to the theoretical charge capacity corresponding to the environmental data.

[0150] For example, environmental data refers to the environmental conditions when the switchable film is used, such as ambient temperature, ambient humidity, and light intensity. Environmental data affects the performance and lifespan of the switchable film. The ambient temperature can be obtained by the temperature sensor on the switchable film, the ambient humidity can be obtained by the vehicle's humidity sensor, and the light intensity can be obtained by the vehicle's sunlight sensor.

[0151] For example, the second update strategy is that when the difference between the actual charge capacity and the theoretical charge capacity of the dimming film exceeds the first set value, the cloud generates an optimization plan based on environmental data to adjust the theoretical charge capacity corresponding to the dimming position of the dimming film to extend the service life of the dimming film.

[0152] For example, the theoretical charge capacity corresponding to the environmental data can be obtained in advance based on experiments and stored in the cloud, or it can be obtained based on a preset algorithm or model on the cloud. For example, for the same dimming level, different ambient temperature ranges can correspond to different theoretical charge capacities, or different light intensity ranges can correspond to different theoretical charge capacities.

[0153] For example, the cloud can pre-collect a large amount of lifespan attenuation data and usage environment data for the dimming film. Based on an algorithm or model, it can analyze the relationship between the lifespan attenuation data and the environment data, and output the theoretical charge capacity used to update the dimming level under the environment data. As more lifespan attenuation data and usage environment data are obtained, the algorithm or model can be iteratively updated.

[0154] This disclosure uses real-time cloud-based monitoring of difference values ​​and environmental data to determine the lifespan degradation of the film and generate optimization strategies to ensure optimal performance. Furthermore, by adjusting the film's dimming settings based on environmental data, the film can better adapt to different usage environments, improving its performance and reliability.

[0155] As an optional embodiment, the operation data further includes geographical location data of the switchable film when it is used;

[0156] The receiving the update strategy sent by the cloud includes:

[0157] Receive a third update strategy sent by the cloud, where the third update strategy is output by the cloud in response to the life decay condition characterizing that the difference exceeds a first set value based on the geographic location data, and the third update strategy is used to set the theoretical charge capacity corresponding to the dimming gear to the theoretical charge capacity corresponding to the geographic location information.

[0158] For example, the geographic location data is the geographic location information when the switchable film is used, and the geographic location data can reflect the long-term environmental conditions of the switchable film, such as climate, light intensity, etc. The geographic location data can be determined by the vehicle's positioning perception system.

[0159] For example, the third update strategy is that when the difference between the actual charge capacity and the theoretical charge capacity of the dimming film exceeds the first set value, the cloud generates an optimization scheme based on the geographic location data, which is used to adjust the theoretical charge capacity corresponding to the dimming position of the dimming film to extend the service life of the dimming film.

[0160] For example, the theoretical charge capacity corresponding to the geographic location data can be obtained in advance based on experiments and stored in the cloud, or it can be obtained based on a preset algorithm or model on the cloud. For example, for the same dimming level, different latitude ranges can correspond to different theoretical charge capacities, or different climate zones can correspond to different theoretical charge capacities.

[0161] For example, the cloud can pre-collect a large amount of lifespan attenuation data and geographic location data of the dimming film. Based on an algorithm or model, it can analyze the relationship between the lifespan attenuation data and the geographic location data, and output the theoretical charge capacity used to update the dimming gear under the geographic location data. As more lifespan attenuation data and geographic location data are obtained, the algorithm or model can be iteratively updated.

[0162] By monitoring the difference and geographic location data in real time, this disclosure can determine the lifespan degradation of the film and generate an optimization strategy to ensure the film's performance remains optimal. By adjusting the film's dimming settings based on geographic location data, the film can better adapt to environmental conditions in different regions, improving its performance and reliability.

[0163] As an optional embodiment, the receiving the update policy sent by the cloud includes:

[0164] Receive a fourth update strategy sent by the cloud, where the fourth update strategy is output by the cloud in response to the life decay condition indicating that the difference is continuously less than or equal to the second set value within a set time period, and the fourth update strategy is used to increase the theoretical charge capacity corresponding to the dimming gear.

[0165] For example, the fourth update strategy is that when the difference between the actual charge capacity and the theoretical charge capacity of the dimming film in the cloud is continuously less than or equal to the second set value within a set time, an optimization solution is directly generated, which can be used to increase the theoretical charge capacity corresponding to the dimming gear of the dimming film.

[0166] For example, the set duration is a pre-set duration, such as three days, one week, or one month, and can be set according to actual circumstances. The second set value is a pre-set reference value and can be set according to actual circumstances. The set duration and the second set value can be used together to determine whether the lifespan of the switchable film has degraded to a point where a replacement strategy is required.

[0167] The second set value can be set to a smaller value, which can be used to indicate that the switchable film has not reached its maximum capacity in actual use, that is, it can indicate that the theoretical charge capacity may be set too low. For example, the second set value can be 0mAh, 0.05mAh, 0.1mAh, etc.

[0168] For example, the cloud can calculate the difference between the theoretical charge capacity and the actual charge capacity based on the operating data of the dimming film and analyze whether the difference remains less than or equal to a second set value for a set period of time. If the difference remains less than or equal to the second set value for the set period of time, the cloud can generate a fourth update strategy and send it to the device controller corresponding to the dimming film, instructing the controller to increase the theoretical charge capacity corresponding to the dimming level according to the fourth update strategy.

[0169] The present disclosure increases the theoretical charge capacity corresponding to the dimming gear when the difference between the actual charge capacity and the theoretical charge capacity is continuously less than or equal to a second set value within a set time period, allowing the dimming film to operate at a higher charge capacity and provide a wider transmittance adjustment range, thereby improving the user experience.

[0170] As an optional embodiment, the operating data further includes at least one of the following: operation data of the dimming gear, environmental data when the dimming film is used, and geographical location data;

[0171] The monitoring of the lifespan attenuation of the dimming film according to the operating data includes:

[0172] The lifespan attenuation of the dimming film is monitored according to at least one of the operation data, the environmental data, and the geographic location data, and the charge capacity data.

[0173] For example, operational data is a record of user operations on the dimming mode of the smart film, including the switching frequency and duration of the dimming mode. Environmental data is the environmental conditions when the smart film is used, such as temperature, humidity, and light intensity. Geographic location data is the geographical location information when the smart film is used. Geographic location data can reflect the environmental conditions in which the smart film is used, or it can be combined with environmental data to reflect the environmental conditions in which the smart film is used, such as climate and light intensity.

[0174] For example, the lifespan decay of the switchable film may be monitored by at least one of operation data, environmental data, and geographic location data, as well as charge capacity data.

[0175] The impact of operational data on the lifespan of the dimming film can be monitored using operational data and charge capacity data. The impact of environmental conditions on the lifespan of the dimming film can be monitored using environmental data and / or geographic location data, as well as charge capacity data. Furthermore, the operational data, environmental data, geographic location data, and charge capacity data can be combined to analyze the impact of different environmental conditions on the lifespan of the dimming film under the same operation, or the impact of different operations on the lifespan of the dimming film under the same environmental conditions, or the impact of different operations on the lifespan of the dimming film under different environmental conditions.

[0176] By comprehensively analyzing a variety of operating data, the life attenuation of the smart film can be evaluated more comprehensively and accurately. Moreover, through long-term data accumulation and analysis in the cloud, the design and material selection of the smart film can be continuously optimized, shortening the development cycle. New technologies can be applied to vehicles more quickly and continuously iterated to improve the service life and stability of the smart film.

[0177] As an optional embodiment, the method further includes:

[0178] Sending the historical operation frequency of the dimming gear to the cloud;

[0179] Receive a fifth update strategy sent by the cloud in response to a target number ratio being less than a third set value, where the target number ratio is a ratio of the historical operation frequency of the dimming gear to the total operation frequency of all dimming gears, and the fifth update strategy is used to disable or cancel the dimming gear.

[0180] For example, the historical operation frequency is the historical number of times a user sets the dimming film to a certain dimming level. The target frequency ratio is the ratio of the historical operation frequency of the dimming level to the total operation frequency of all dimming levels.

[0181] For example, the third set value is a pre-set reference value and can be set according to actual conditions. The third set value can be used to determine whether the historical operation frequency of the dimming gear is too low. For example, the third set value can be 2%, 1%, etc.

[0182] For example, the fifth update strategy is an optimization solution generated by the cloud when the target number ratio is less than the third set value, and is used to disable or cancel the dimming gear.

[0183] For example, in a vehicle, the vehicle's domain controller can record the historical operation frequency of each dimming level and send this information to the cloud based on the historical operation frequency. Based on the historical operation frequencies of multiple dimming levels, the total operation frequency of all dimming levels can be determined by the vehicle or the cloud. The cloud can calculate the target percentage of each dimming level's historical operation frequency relative to the total operation frequency. When the target percentage is less than a third set value, the cloud can send a fifth update policy to the vehicle. The vehicle can then receive the fifth update policy and disable or cancel the dimming level.

[0184] In addition, disabling or canceling dimming levels that are less frequently used by users can reduce the dimming level adjustment process and save adjustment time in some scenarios.

[0185] In this way, the present disclosure can continuously optimize the dimming gear setting of the dimming film based on the user's actual usage scenarios, so that the adjusted dimming gear is more in line with the user's usage habits and improve the user experience.

[0186] As an optional embodiment, the charge capacity data includes theoretical charge capacity and actual charge capacity;

[0187] Obtain the charge capacity data of the dimming film in the dimming gear, including:

[0188] Obtaining current data, voltage data, and charging time of the dimming film at the dimming gear;

[0189] determining the theoretical charge capacity based on the voltage data and a set relationship between voltage and charge capacity;

[0190] The actual charge capacity is determined according to the current data and the charging time.

[0191] For example, the voltage data is the voltage measurement value of the dimming film in the dimming gear. The current data is the current measurement value of the dimming film in the dimming gear. The charging time is the time required for the dimming film to charge in the dimming gear.

[0192] For example, the correspondence between voltage and theoretical charge capacity can be pre-set before the dimming film product leaves the factory. For example, the correspondence can be a table or a graph showing the relationship between voltage and theoretical charge capacity. In the correspondence between voltage and theoretical charge capacity, different dimming levels correspond to different theoretical charge capacities. The dimming controller adjusts the dimming level by adjusting the voltage across the dimming film. In other words, by obtaining the voltage across the dimming film, the theoretical charge capacity corresponding to the current dimming level can be determined.

[0193] For example, the dimming controller corresponding to the dimming film can collect voltage and current data and record the charging time. The current data can be integrated with the time parameter to obtain the actual charge capacity during charging and discharging. The theoretical charge capacity corresponding to the dimming position can be determined based on the acquired voltage data and the corresponding relationship between voltage and theoretical charge capacity.

[0194] The present invention can accurately calculate the theoretical charge capacity and actual charge capacity by real-time monitoring of current, voltage and charging time, thereby determining the life attenuation of the dimming film. It can further reduce the operating time of the dimming film under high load conditions and extend its service life by adjusting the dimming gear.

[0195] As an optional embodiment, the operation data further includes environmental data when the switchable film is used; and the method further includes:

[0196] According to the environmental data, prompt information for prompting the user to adjust the gear is output.

[0197] For example, the prompt information is used to suggest that the user adjust the setting of the dimming film to achieve heat insulation, sun protection, or privacy protection. The prompt information can be output via voice data or a display. For example, in a vehicle, the prompt information can be displayed on the vehicle's display screen or announced via voice messages.

[0198] For example, when a user sets the dimming mode of the switchable film to automatic, the vehicle can automatically determine and adjust the mode based on the weather. The vehicle can then display a prompt to the user after the mode adjustment is complete, or it can display a prompt before the mode adjustment is complete, reminding the user that the mode adjustment is about to take place.

[0199] For example, the environment data can be used to determine whether the current use environment of the switchable film requires adjustment of the gear position. If the environment data indicates that the current gear position is not suitable for the current environment, a prompt message is generated to suggest that the user adjust the gear position.

[0200] The present disclosure outputs prompt information through environmental data, which can help users better understand and operate the dimming film and improve user experience.

[0201] As an optional embodiment, the method further includes:

[0202] In response to the completion of the gear adjustment operation on the dimming film, the operation data is sent to the cloud.

[0203] For example, the gear adjustment operation is the user's adjustment of the dimming gear of the dimming film, wherein the user can control the gear adjustment through voice control, or through the display or buttons. Operational data is the data generated by the dimming film during use, including charge capacity data, environmental data, operation data, etc.

[0204] For example, the gear adjustment operation of the dimming film can be continuously monitored to detect whether the user has completed the gear adjustment. Taking the vehicle's domain controller as an example, when the user triggers the gear adjustment operation, the vehicle domain controller sends a gear adjustment signal to the dimming controller. After receiving the adjustment success signal from the dimming controller, the vehicle domain controller determines that the gear adjustment operation of the dimming film is completed.

[0205] The present invention sends the operating data to the cloud after the gear adjustment operation is completed, without uploading all the operating data in real time, which can reduce the storage capacity of the cloud.

[0206] Reference Figure 2 , Figure 2 FIG. 1 is a flow chart showing a method for monitoring the life of a dimming film according to an exemplary embodiment. Figure 2 As shown, the life monitoring method of the dimming film can be applied to cloud devices, such as cloud servers, such as mobile phone clouds, vehicle clouds of smart network cars, etc., and includes the following steps.

[0207] In step S201, operating data of the dimming film when in use is received from a vehicle, wherein the operating data includes charge capacity data of the dimming film in a dimming gear;

[0208] In step S202, the lifespan attenuation of the dimming film is monitored according to the operating data.

[0209] For example, a dimming film is an electronic light control product that is commonly used for sun protection, intelligent color control, privacy protection, etc. Specifically, the dimming film for automobiles can be installed on the front and rear windshields, windows, triangular windows, front and rear partitions, skylights, and other glass surfaces.

[0210] For example, the dimming film can cause the material to undergo an oxidation-reduction reaction by applying an electric current to change the color, switch between transparent and opaque states, and adjust the degree of opacity, etc., which can achieve the purposes of sun protection or privacy protection.

[0211] For example, the dimming film can have multiple dimming gears when controlled, and different dimming gears can correspond to different dimming transparencies and / or different dimming gears can correspond to different colors. The dimming film can be controlled by a dimming controller corresponding to the dimming film.

[0212] In a vehicle, a gear adjustment signal can be sent to a dimming controller through a vehicle controller, such as a T-BOX, an intelligent driving domain controller, a gateway controller, a cockpit domain controller, other domain controllers, etc., so that the dimming controller can adjust the transparency or color of the dimming film according to the dimming gear included in the gear adjustment signal.

[0213] For example, charge capacity data is the amount of charge stored per unit area in the dimming mode of the dimming film. Charge capacity data can be used to quantify the dimming performance of the film, and its variation is closely related to the lifespan of the film. Charge capacity can be correlated with the transparency or color of the film. For example, for the same dimming film, there is a negative correlation between charge capacity and transparency: the greater the charge capacity, the lower the transparency. For example, different charge capacity values ​​correspond to different colors.

[0214] For example, charge capacity data can be further obtained by obtaining current data, voltage data, and time parameters of the dimming film at the current dimming level. For example, the charge capacity data may include the actual charge capacity and theoretical charge capacity of the dimming film. Different dimming levels correspond to different theoretical charge capacities.

[0215] For example, the vehicle can obtain the operating data of the dimming film when it is in use through the vehicle's controller and interact with the cloud to obtain the operating data of the dimming film when it is in use in the cloud. In addition, the cloud can monitor the life attenuation of the dimming film based on the operating data.

[0216] This disclosure uses the cloud to receive operational data from a vehicle's dimming film during use and monitors the film's lifespan based on this operational data. The operational data includes the film's charge capacity data when in the dimming mode. This allows the cloud to monitor the film's lifespan in real time and remotely, facilitating timely detection of potential failure points for the film's dimming function and providing data support for its design and improvement.

[0217] As an optional embodiment, the charge capacity data includes theoretical charge capacity and actual charge capacity; and monitoring the lifespan attenuation of the switchable film based on the operating data includes:

[0218] determining a difference between the actual charge capacity and the theoretical charge capacity;

[0219] The life attenuation of the dimming film is determined according to the numerical relationship between the difference and the set value.

[0220] For example, the theoretical charge capacity is the amount of charge that the dimming film can theoretically store / release when charging and discharging at that dimming setting. The actual charge capacity is the amount of charge that the dimming film can actually store / release when charging and discharging at that dimming setting. Typically, the actual charge capacity is less than or equal to the theoretical charge capacity.

[0221] For example, the difference between the actual charge capacity and the theoretical charge capacity is the numerical difference between the actual charge capacity and the theoretical charge capacity, which can be used to reflect the degradation of the performance of the dimming film. The set value can be a pre-set reference value for judging the degree of degradation of the dimming film life, which is usually determined based on experiments or experience, such as 5mAh or 0mAh.

[0222] For example, the difference between the actual charge capacity and the theoretical charge capacity can be determined based on the difference between the actual charge capacity and the theoretical charge capacity, and the difference can be used to reflect changes in the performance of the dimming film. Different environments, different geographical locations, and different user operations may lead to differences between the actual charge capacity and the theoretical charge capacity. That is, the actual charge capacity may fluctuate based on the environment, geographical location, and user operating habits of the dimming film. By setting a set value, the performance life degradation of the dimming film can be characterized based on the numerical relationship between the difference and the set value.

[0223] For example, the life attenuation condition can represent whether the life of the switchable film is greatly attenuated, slightly attenuated, attenuated or not attenuated, etc. The set value can be set or calibrated according to actual design requirements.

[0224] For example, when the life decay condition is set to indicate whether the life of the dimming film has decayed or not decayed, the set value can be set to one, such as 5mAh. When the difference between the actual charge capacity and the theoretical charge capacity is greater than 5mAh, the life decay condition can indicate that the life of the dimming film has decayed; when the difference between the actual charge capacity and the theoretical charge capacity is less than or equal to 5mAh, the life decay condition can indicate that the life of the dimming film has not decayed.

[0225] For example, when the life decay situation is set to be used to characterize the degree of life decay of the dimming film as large, small or no decay, the set value can be set to two, such as 2mAh and 6mAh. Among them, when the difference between the actual charge capacity and the theoretical charge capacity is greater than 6mAh, the life decay situation can characterize the degree of life decay of the dimming film as large; when the difference between the actual charge capacity and the theoretical charge capacity is less than or equal to 6mAh and greater than 2mAh, the life decay situation can characterize the degree of life decay of the dimming film as small; when the difference between the actual charge capacity and the theoretical charge capacity is less than or equal to 2mAh, the life decay situation can characterize the degree of life decay of the dimming film as no decay.

[0226] The present invention determines the life attenuation of the dimming film through the numerical relationship between the difference between the theoretical charge capacity and the actual charge capacity and the set value, and can issue an early warning to remind the user to perform maintenance or replacement, thereby ensuring the normal use of the dimming film and improving the user experience.

[0227] As an optional embodiment, the method further includes:

[0228] At least according to the life attenuation condition, an update strategy for the dimming gear is sent to the vehicle.

[0229] For example, the update strategy is an optimization solution generated by the cloud for the dimming gear according to the life attenuation of the dimming film. The dimming gear of the dimming film can be adjusted through the update strategy to extend its service life or improve its performance.

[0230] For example, the cloud can push a reminder message to the vehicle, and the vehicle can prompt the user through the vehicle computer screen or voice prompts to recalibrate the dimming position at the car after-sales service center. Alternatively, the cloud can also push a reminder message to the vehicle, and when the user confirms that the update is possible, the cloud can send a system upgrade package to the vehicle via Over The Air (OTA) technology, so that the vehicle can update the dimming position based on the system upgrade package.

[0231] For example, the cloud can determine the lifespan degradation of the dimming film based on the difference between the actual charge capacity and the theoretical charge capacity, and generate an optimization plan for updating the dimming gear based on the lifespan degradation. The cloud can also analyze the factors that may be related to the lifespan degradation of the dimming film using the received operating data, and output a strategy for updating the dimming gear based on the factors that may be related to the lifespan degradation.

[0232] As an optional embodiment, the sending of an update strategy for the dimming gear to the vehicle at least based on the life attenuation condition includes:

[0233] In response to the lifespan attenuation condition indicating that the difference exceeds a first set value, a first update strategy is sent to the vehicle, where the first update strategy is used to reduce a theoretical charge capacity corresponding to the dimming gear.

[0234] For example, when the difference between the actual charge capacity and the theoretical charge capacity of the dimming film exceeds a first set value, the cloud directly generates a first update strategy, which can be used to reduce the theoretical charge capacity corresponding to the dimming gear of the dimming film.

[0235] For example, the first set value is a pre-set reference value that can be set according to actual conditions. The first set value can be used to determine whether the life of the dimming film has decreased to a level that requires an update strategy. For example, the first set value can be 5mAh, 8mAh, etc.

[0236] For example, the cloud can calculate the difference between the theoretical and actual charge capacities based on the operating data of the dimming film and analyze whether the difference exceeds a first set value. If the difference exceeds the first set value, the cloud generates a first update strategy and sends it to the vehicle corresponding to the dimming film, instructing the vehicle to reduce the theoretical charge capacity corresponding to the dimming gear according to the first update strategy.

[0237] The present disclosure reduces the theoretical charge capacity corresponding to the dimming gear, thereby reducing the number of overcharge and overdischarge and the charge capacity of the dimming film, that is, reducing the operating time of the dimming film under high load conditions, thereby extending the service life of the dimming film, while having little impact on the performance of the dimming film.

[0238] As an optional embodiment, the operation data further includes environmental data when the switchable film is used;

[0239] The sending, to the vehicle, an update strategy for the dimming gear at least according to the life attenuation condition, includes:

[0240] In response to the life decay condition characterizing that the difference exceeds a first set value, a second update strategy is sent to the vehicle based on the environmental data, and the second update strategy is used to set the theoretical charge capacity corresponding to the dimming gear to the theoretical charge capacity corresponding to the environmental data.

[0241] For example, environmental data refers to the environmental conditions when the switchable film is used, such as ambient temperature, ambient humidity, and light intensity. Environmental data affects the performance and lifespan of the switchable film. The ambient temperature can be obtained by the temperature sensor on the switchable film, the ambient humidity can be obtained by the vehicle's humidity sensor, and the light intensity can be obtained by the vehicle's sunlight sensor.

[0242] For example, when the difference between the actual charge capacity and the theoretical charge capacity of the dimming film exceeds a first set value, the cloud generates a second update strategy based on environmental data. The second update strategy is used to adjust the theoretical charge capacity corresponding to the dimming position of the dimming film to extend the service life of the dimming film.

[0243] For example, the theoretical charge capacity corresponding to the environmental data can be obtained in advance based on experiments and stored in the cloud, or it can be obtained based on a preset algorithm or model on the cloud. For example, for the same dimming level, different ambient temperature ranges can correspond to different theoretical charge capacities, or different light intensity ranges can correspond to different theoretical charge capacities.

[0244] For example, the cloud can pre-collect a large amount of lifespan attenuation data and usage environment data for the dimming film. Based on an algorithm or model, it can analyze the relationship between the lifespan attenuation data and the environment data, and output the theoretical charge capacity used to update the dimming level under the environment data. As more lifespan attenuation data and usage environment data are obtained, the algorithm or model can be iteratively updated.

[0245] This disclosure uses real-time cloud-based monitoring of difference values ​​and environmental data to determine the lifespan degradation of the film and generate optimization strategies to ensure optimal performance. Furthermore, by adjusting the film's dimming settings based on environmental data, the film can better adapt to different usage environments, improving its performance and reliability.

[0246] As an optional embodiment, the operation data further includes geographical location data of the switchable film when it is used;

[0247] The sending, to the vehicle, an update strategy for the dimming gear at least according to the life attenuation condition, includes:

[0248] In response to the life decay condition characterizing that the difference exceeds a first set value, a third update strategy is sent to the vehicle based on the geographic location data, and the third update strategy is used to set the theoretical charge capacity corresponding to the dimming gear to the theoretical charge capacity corresponding to the geographic location information.

[0249] For example, the geographic location data is the geographic location information when the switchable film is used, and the geographic location data can reflect the long-term environmental conditions of the switchable film, such as climate, light intensity, etc. The geographic location data can be determined by the vehicle's positioning perception system.

[0250] For example, when the difference between the actual charge capacity and the theoretical charge capacity of the dimming film exceeds a first set value, the cloud generates a third update strategy based on the geographic location data. The third update strategy can be used to adjust the theoretical charge capacity corresponding to the dimming position of the dimming film to extend the service life of the dimming film.

[0251] For example, the theoretical charge capacity corresponding to the geographic location data can be obtained in advance based on experiments and stored in the cloud, or it can be obtained based on a preset algorithm or model on the cloud. For example, for the same dimming level, different latitude ranges can correspond to different theoretical charge capacities, or different climate zones can correspond to different theoretical charge capacities.

[0252] For example, the cloud can pre-collect a large amount of lifespan attenuation data and geographic location data of the dimming film. Based on an algorithm or model, it can analyze the relationship between the lifespan attenuation data and the geographic location data, and output the theoretical charge capacity used to update the dimming gear under the geographic location data. As more lifespan attenuation data and geographic location data are obtained, the algorithm or model can be iteratively updated.

[0253] By monitoring the difference and geographic location data in real time, this disclosure can determine the lifespan degradation of the film and generate an optimization strategy to ensure the film's performance remains optimal. By adjusting the film's dimming settings based on geographic location data, the film can better adapt to environmental conditions in different regions, improving its performance and reliability.

[0254] As an optional embodiment, the sending of an update strategy for the dimming gear to the vehicle at least based on the life attenuation condition includes:

[0255] In response to the life decay condition indicating that the difference is continuously less than or equal to a second set value within a set time period, a fourth update strategy is sent to the vehicle, where the fourth update strategy is used to increase the theoretical charge capacity corresponding to the dimming gear.

[0256] For example, when the difference between the actual charge capacity and the theoretical charge capacity of the dimming film in the cloud is continuously less than or equal to the second set value within a set time period, a fourth update strategy is generated. The fourth update strategy can be used to increase the theoretical charge capacity corresponding to the dimming position of the dimming film.

[0257] For example, the set duration is a pre-set duration, such as three days, one week, or one month, and can be pre-set based on actual conditions. The second set value is a pre-set reference value and can be set based on actual conditions. The set duration and the second set value can be used together to determine whether the lifespan of the switchable film has degraded to a point where a replacement strategy is required.

[0258] The second set value can be set to a smaller value, which can be used to indicate that the switchable film has not reached its maximum capacity in actual use, that is, it can indicate that the theoretical charge capacity may be set too low. For example, the second set value can be 0mAh, 0.05mAh, 0.1mAh, etc.

[0259] For example, the cloud can calculate the difference between the theoretical charge capacity and the actual charge capacity based on the operating data of the dimming film and analyze whether the difference remains less than or equal to a second set value for a set period of time. If the difference remains less than or equal to the second set value for the set period of time, the cloud can generate a fourth update strategy and send it to the device controller corresponding to the dimming film, instructing the controller to increase the theoretical charge capacity corresponding to the dimming level according to the fourth update strategy.

[0260] The present disclosure increases the theoretical charge capacity corresponding to the dimming gear when the difference between the actual charge capacity and the theoretical charge capacity is continuously less than or equal to a second set value within a set time period, allowing the dimming film to operate at a higher charge capacity and provide a wider transmittance adjustment range, thereby improving the user experience.

[0261] As an optional embodiment, the operating data further includes at least one of the following: operation data of the dimming gear, environmental data when the dimming film is used, and geographical location data;

[0262] The monitoring of the lifespan attenuation of the dimming film according to the operating data includes:

[0263] The lifespan attenuation of the dimming film is monitored according to at least one of the operation data, the environmental data, and the geographic location data, and the charge capacity data.

[0264] For example, operational data is a record of user operations on the dimming mode of the smart film, including the switching frequency and duration of the dimming mode. Environmental data is the environmental conditions when the smart film is used, such as temperature, humidity, and light intensity. Geographic location data is the geographical location information when the smart film is used. Geographic location data can reflect the environmental conditions in which the smart film is used, or it can be combined with environmental data to reflect the environmental conditions in which the smart film is used, such as climate and light intensity.

[0265] For example, the lifespan decay of the switchable film may be monitored by at least one of operation data, environmental data, and geographic location data, as well as charge capacity data.

[0266] The impact of operational data on the lifespan of the dimming film can be monitored using operational data and charge capacity data. The impact of environmental conditions on the lifespan of the dimming film can be monitored using environmental data and / or geographic location data, as well as charge capacity data. Furthermore, the operational data, environmental data, geographic location data, and charge capacity data can be combined to analyze the impact of different environmental conditions on the lifespan of the dimming film under the same operation, or the impact of different operations on the lifespan of the dimming film under the same environmental conditions, or the impact of different operations on the lifespan of the dimming film under different environmental conditions.

[0267] By comprehensively analyzing a variety of operating data, the life attenuation of the smart film can be evaluated more comprehensively and accurately. Moreover, through long-term data accumulation and analysis in the cloud, the design and material selection of the smart film can be continuously optimized, shortening the development cycle. New technologies can be applied to vehicles more quickly and continuously iterated to improve the service life and stability of the smart film.

[0268] As an optional embodiment, the method further includes:

[0269] receiving a historical operation frequency of the dimming gear sent by the vehicle;

[0270] In response to the target number ratio being less than a third set value, a fifth update strategy is sent to the vehicle, where the target number ratio is the ratio of the historical operation frequency of the dimming gear to the total operation frequency of all dimming gears, and the fifth update strategy is used to disable or cancel the dimming gear.

[0271] For example, the historical operation frequency is the historical number of times a user sets the dimming film to a certain dimming level. The target frequency ratio is the ratio of the historical operation frequency of the dimming level to the total operation frequency of all dimming levels.

[0272] For example, the third set value is a pre-set reference value and can be set according to actual conditions. The third set value can be used to determine whether the historical operation frequency of the dimming gear is too low. For example, the third set value can be 2%, 1%, etc.

[0273] For example, the fifth update strategy is an optimization solution generated by the cloud when the target number ratio is less than the third set value, and is used to disable or cancel the dimming gear.

[0274] For example, in a vehicle, the vehicle's domain controller can record the historical operation frequency of each dimming level and send this information to the cloud based on the historical operation frequency. Based on the historical operation frequencies of multiple dimming levels, the total operation frequency of all dimming levels can be determined by the vehicle or the cloud. The cloud can calculate the target percentage of each dimming level's historical operation frequency relative to the total operation frequency. When the target percentage is less than a third set value, the cloud can send a fifth update policy to the vehicle. The vehicle can then receive the fifth update policy and disable or cancel the dimming level.

[0275] In addition, disabling or canceling dimming levels that are less frequently used by users can reduce the dimming level adjustment process and save adjustment time in some scenarios.

[0276] In this way, the present disclosure can continuously optimize the dimming gear setting of the dimming film based on the user's actual usage scenarios, so that the adjusted dimming gear is more in line with the user's usage habits and improve the user experience.

[0277] As an optional embodiment, the method further includes:

[0278] The operating data is stored and displayed.

[0279] For example, the operating data sent by the vehicle can be stored in a cloud server for access and management at any time. The operating data stored in the cloud can be displayed on a cloud dashboard and presented to users or administrators in a visual manner, which can be achieved through a web page or application.

[0280] By storing and displaying operational data, users can check the operating status of the switchable film at any time through the cloud, enabling remote monitoring and management, and improving management efficiency. Furthermore, historical data stored in the cloud can be used for retrospective analysis, helping users understand the long-term performance trends of the switchable film and providing a basis for maintenance and replacement.

[0281] As a specific embodiment, see Figure 3 Taking the example of a vehicle user switching the gears of the dimming film through the vehicle display, voice or mobile phone application, the information interaction process between the dimming film, dimming controller, vehicle domain controller / cockpit domain controller and cloud devices is shown.

[0282] Among them, the dimming film is a dimming film that uses electrochromic technology (EC), and the cloud device is a cloud server on the TSP (Telematics Service Provider) side.

[0283] For example, vehicle users can switch the EC dimming film's gear position using the vehicle's HMI (Human Machine Interface), voice, or mobile phone. The film's status data and user operations are then uploaded to the cloud. The cloud can analyze and process the data to determine the film's relative lifespan and issue early warnings based on that lifespan. Dimming gear settings can also be updated over-the-air (OTA) to extend the film's lifespan.

[0284] In some possible implementations, the cloud can collect the operating data of the dimming film corresponding to the vehicle ID (Identity document), as well as the attenuation data of the dimming film in different usage scenarios and different geographical locations based on the vehicle ID, and perform data analysis to predict in advance the time point when the dimming function of the dimming film will fail.

[0285] For example, the operating data may include temperature, voltage, current, time parameters, and the like.

[0286] like Figure 4 As shown, the interface between the dimming controller and the EC dimming film is defined, and the framed area may represent the internal structure of the dimming controller.

[0287] Among them, NTC is a thermistor that can be used to collect temperature information of the dimming film. The dimming film is very sensitive to temperature, and both low and high temperatures will have a certain impact on the performance and life of the dimming film.

[0288] The MCU (Microcontroller Unit) is a highly integrated embedded control chip and the core component of the dimming controller. Its core functions include device control, data processing, and communication interaction. By integrating modules such as the CPU (Central Processing Unit), memory, and peripheral interfaces, it achieves real-time control and intelligent management of electronic systems.

[0289] Among them, the BUCK circuit is a DC-DC converter based on the principle of inductive energy storage. Its core function is to convert the input DC voltage into an adjustable low-voltage output to meet the power supply requirements of different circuits.

[0290] ADC stands for analog-to-digital converter, or A / D converter, which converts analog signals into digital signals. An SBC (System Basis Chip) is a highly integrated integrated circuit chip that integrates multiple functions, including power supply, communications, monitoring and diagnostics, and safety monitoring.

[0291] Among them, the MOS (Metal-Oxide-Semiconductor Field-Effect Transistor) driving circuit is used to efficiently and accurately control the current and voltage of the dimming film.

[0292] For example, the EC dimming film and the dimming controller can be connected via hard wiring, including two wires for charging and discharging the film, an NTC temperature sensor for the film, and two wires for grounding. The wiring harness should be no longer than 2 meters to avoid voltage drops in the wiring harness that could cause a large deviation between the controller output and the actual output at the film end.

[0293] For example, the dimming controller and the domain controller / cabin controller are connected via a LIN or CAN network, and can interact through defined transceiver signals. The specific signals include: the actual charge capacity after adjustment to different gears, the temperature of the dimming film, and the dimming gear information.

[0294] For example, the domain controller / cockpit controller uploads data to the cloud via the 5G network and can interact through defined sending and receiving signals. Specific signals include: the frequency of user HMI and voice operation gears, the actual charge capacity of different gears, the timing of adjustment operations, dimming gear information and dimming film temperature.

[0295] Specifically, the car computer can display a visual page based on the above signals, such as the frequency of user operation of a certain gear in the past six months or a year, and the attenuation capacity of the dimming film. The car computer can also output OTA or operation suggestions. For example, it can remind users to adjust the gear according to weather conditions to achieve heat insulation and sun protection; or set the gear to automatic so that the car computer can automatically determine and adjust the gear according to weather conditions.

[0296] For example, the dimming controller can adjust the voltage value of the dimming film to achieve different transparency levels. At the same time, the dimming controller collects the current of EC+ and EC- to calculate the charge capacity of the charge and discharge, which corresponds to the transparency of the dimming film.

[0297] The dimming controller adjusts the voltage difference between EC+ and EC- by adjusting the output voltage of the internal buck circuit. The dimming controller uses the internal ADC to collect the voltage values ​​corresponding to EC+ and EC-, as well as the corresponding current values. Because the current value is highly correlated with the charge capacity, high current acquisition accuracy is required.

[0298] For example, the dimming controller can calculate the actual and theoretical charge capacities of the dimming film using temperature, voltage, current, and time parameters. The actual charge capacity corresponds to the transparency of the film. The dimming controller adjusts the voltage across the dimming film based on the gear adjustment signal from the domain controller / cabin controller. When the charge capacity reaches the theoretical charge capacity corresponding to the gear position, dimming is complete. At this point, the dimming controller feeds the corresponding gear position signal back to the domain controller / cabin controller.

[0299] For example, in the dimming controller software corresponding to the dimming film, the theoretical charge capacity corresponding to different dimming gears can be written into the software before leaving the factory, as shown in Table 1 below.

[0300] Table 1 Theoretical charge capacity corresponding to different dimming gears and actual charge capacity corresponding to different dimming gears after use

[0301] Dimming position Theoretical charge capacity Actual charge capacity 1 Q1 Q1A 2 Q2 Q2A 3 Q3 Q3A 4 Q4 Q4A 5 Q5 Q5A

[0302] In actual use, if the dimming film is frequently switched between different settings and under different temperature conditions, the charge capacity corresponding to different settings will decrease to a certain extent. The actual charge capacity corresponding to different dimming settings is shown in the third column of Table 1. The dimming controller calculates the actual charge capacity by integrating the current value and time parameters, and the dimming controller can provide real-time feedback of the actual charge capacity and the corresponding theoretical charge capacity to the domain controller / cockpit controller.

[0303] At the same time, the temperature value has a great influence on the service life of the dimming film. The dimming controller can feed back the temperature collected from the dimming film to the domain controller / cabin controller.

[0304] For example, the domain controller / cockpit controller can feed back user operation data to the cloud, including the user's operation habits and frequency. This operation data can include the user's operation of the dimming film gear shifting through voice, front and rear screens, etc. The user's operation data is obtained after the dimming operation is completed and the domain controller / cockpit controller receives the adjustment success signal from the dimming controller.

[0305] If the user frequently dims the light, the system may not respond to the user's dimming operation, but the system can still record and upload the data to the cloud. However, all data is uploaded after the dimming operation is completed, not in real time, to reduce the storage capacity required on the cloud.

[0306] The domain controller / cabin controller can upload the actual charge capacity during dimming to the cloud. This data is uploaded not in real time, but after the complete dimming operation, to reduce cloud storage capacity requirements.

[0307] Among them, the domain controller / cockpit controller can record the time when the dimming operation event occurs and upload it to the cloud, and upload the temperature feedback from the dimming controller to the cloud. The cloud can store the above signals in real time and display them on the dashboard.

[0308] For example, after receiving data uploaded by the domain controller / cockpit controller, the cloud can remind the user to calibrate the theoretical charge capacity of the dimming film when preset judgment conditions are met. For example, if the difference between the actual charge capacity and the theoretical charge capacity is large, such as greater than 5mAh, it means that the film is severely attenuated. The user can be prompted to go to the car after-sales service center for calibration to reduce the theoretical charge capacity through a large-screen HMI or other means. This can reduce the number of overcharge and over-discharge events and the amount of charge, thereby extending the service life of the dimming film while minimizing the impact on its performance.

[0309] For example, users have different natural environments and usage environments in different geographical locations, and can also obtain the vehicle's geographical location data. The cloud can use geographical location data and other information to analyze the attenuation state of the theoretical charge capacity of the dimming film in different geographical locations for each dimming gear, as well as the theoretical charge capacity that can be set in different geographical locations, so as to adapt to local conditions and even to individual conditions.

[0310] For example, the cloud can set filtering criteria based on collected data, such as selecting the user habits of the dimming film in multiple cities at the same latitude in the south to monitor the film's capacity decay. When the actual charge capacity falls below the set value, a pop-up window or other means will automatically prompt the user to calibrate the capacity, thereby achieving a better film user experience and preventing damage to the skylight.

[0311] For example, by using the user's operational data on the switchable film, the function definition can be further optimized according to the user's usage habits and preferences. For example, if the user has little adjustment for the 234 gears between 1-5, the intermediate gears can be eliminated or reduced, etc.

[0312] For example, the analysis of the buried data used by users can be used to determine whether the current parameter design of the dimming film is over-designed. For example, over a long period of time, the actual charge capacity of the dimming film is the same as the set theoretical charge capacity. In other words, the dimming film has never reached the theoretical limit in actual use, indicating that the theoretical charge capacity is set too low. The theoretical charge capacity can be appropriately increased to give users a better film usage experience and provide a wider transmittance adjustment range, so that the dimming film has better transmittance performance in different dimming gears.

[0313] The EC dimming controller can implement OTA functionality. After determining the appropriate theoretical charge capacity in the cloud, it can push FOTA packages to users via the cloud OTA to update the system in real time. It can also remind users to calibrate the system using diagnostic tools at the aftermarket.

[0314] The present invention discloses sustainable data monitoring and feedback, which can effectively monitor the actual status of the dimming film, study and analyze the life attenuation data of the dimming film in different usage scenarios and different regions, and predict the time point when the dimming function will fail in advance.

[0315] Among them, for the new technology of dimming film, the research of the material itself requires a lot of manpower and time. However, the life monitoring method of the dimming film disclosed in this invention can shorten the development cycle, apply the new technology to vehicles more quickly, and continue to iterate.

[0316] Based on the operating data of the dimming film obtained from the TSP cloud and through the analysis of the usage habits of different users, the present invention can reversely infer the strategy to extend the life of the dimming film, and improve and extend the life of the dimming film through software OTA, or adjust the dimming gear to a data scenario that conforms to the user's usage habits.
