Referring to fig. 2, a schematic diagram of an implementation environment provided in one embodiment of the present application is shown.

In the embodiment of the present application, the electronic device 200 is merely taken as an example of an electronic device for explanation.

Referring to fig. 3, a schematic structural diagram of an electronic device 200 according to an embodiment of the present application is shown. The electronic device 200 includes a central host 310, a control module 320 of the electrochromic device 100. Wherein the central host 310 is connected to the control module 320 of the electrochromic device 100, and the control module 330 of the electrochromic device 100 is connected to each electrochromic device 100 in the electronic apparatus 300, where each electrochromic device 100 includes a side window glass 1, a side window glass 2, a sky curtain glass, and so on.

In the embodiment of the present application, the central control host 310 is configured to receive the gear adjustment signal and send the gear adjustment signal to the control module 320 of the electrochromic device 100. The control module 320 of the electrochromic device 100 performs gear adjustment on the electrochromic device based on the actual value of the current working gear of the electrochromic device under the condition that the gear adjustment signal is received and the condition that the first preset condition is met is monitored, so that the problem that the gear adjustment result is inaccurate when the actual value and the stored value of the current working gear of the electrochromic device deviate can be solved, and the accuracy of gear adjustment is improved.

In some embodiments, the electronic device 200 further comprises a center control screen 330, the center control screen 300 displaying a shift control bar of the electrochromic device 100, wherein the adjustment control bar comprises an adjustable control that a user can drag to trigger a shift adjustment signal for the electrochromic device 100.

In other embodiments, the electronic device 200 further includes a sound collection device, through which the voice signal sent by the user is collected, and the subsequent central control host 310 performs voice-to-text processing and semantic analysis on the collected voice signal to monitor whether the gear adjustment signal for the electrochromic device 100 is received.

The physical controls may be buttons, knobs, levers, and the like. Taking an entity control as an example of a knob, the knob comprises an indication part, different gear identifiers of the electrochromic device are displayed on the periphery of the knob, and a user can rotate the knob to enable the indication part to point to a desired working gear, so that a gear adjusting signal for the electrochromic device 100 is triggered.

Referring to fig. 4, a flowchart of a control method of an electrochromic device according to an embodiment of the present application is shown. The method is applied to an electronic device including an electrochromic device, and includes the following process.

S401, after acquiring a gear adjustment signal for an electrochromic device, acquiring a first gear based on the gear adjustment signal.

The first gear is used for representing a desired value of an operating gear of the electrochromic device, and the desired value can be set by a user or can be adaptively determined by the electronic equipment according to the ambient brightness. The electronic device may acquire the gear adjustment signal in several ways as follows.

In some embodiments, the display interface of the electronic device includes an adjustment function option of the electrochromic device, after receiving a trigger signal for the adjustment function option, the display interface displays a gear shifting control bar of the electrochromic device, where the gear shifting control bar includes an adjustable control, different positions of the adjustable control on the gear shifting control bar correspond to different gears of the electrochromic device, and when a user performs a drag operation on the adjustable control, a drag operation signal received by the electronic device is a gear adjusting signal for the electrochromic device, and after the drag operation disappears, a gear corresponding to a position of the adjustable control on the gear shifting control bar is a first gear.

Referring in conjunction to FIG. 5, a schematic diagram of gear adjustment provided by one embodiment of the present application is shown. The center control screen 330 displays a shift control bar 510, the shift control bar 510 including an adjustable control 520, and a user drags the adjustable control 520 to change the position of the adjustable control 520 on the shift control bar 510 to trigger a shift adjustment signal for the electrochromic device.

In other embodiments, the electronic device is provided with a voice capturing device (such as a microphone) through which a voice signal is captured, and in case the voice signal includes a specified keyword, it is determined that a gear adjustment signal is received. The above specified keywords include names, numbers, and the like of electrochromic devices. The electronic device may convert the speech signal into text information and then semantically recognize the text information to determine the first gear.

For example, after the user says "raise the awning glass by 2 steps", the electronic device performs voice-to-word processing and semantic recognition on the collected voice signal, determines that the first step is the sum of the marking value of the current step of the awning glass and 2, and when the marking value is 4, the first step is 6 steps. The mark value refers to the gear of the electrochromic device recorded and stored by the electronic equipment. The electronic device may read the value of the gear field or determine the marking value based on the position of the adjustable control on the upshift control bar. For another example, after the user speaks "adjust the sky screen to 5 th gear" and the electronic device performs text conversion and semantic recognition on the collected voice signal, it is determined that the first gear is 5 th gear.

In other embodiments, the electronic device may also be provided with an entity control for the electrochromic device, the electronics receiving the gear adjustment signal in accordance with a trigger signal for the entity control. For example, the electronic device is provided with a knob, the knob comprises an indication part, different gears of the gear adjusting signal are marked on the periphery of the knob, and after the electronic device receives the rotating signal aiming at the knob, the gear indicated by the indication part is determined to be the first gear when the rotating signal disappears.

In other embodiments, the electronic device determines the first gear based on the current ambient brightness if a change in ambient brightness is detected. The change of the ambient brightness means that the absolute value of the difference between the ambient brightness value at the first moment and the ambient brightness value at the second moment is larger than the absolute value of the preset difference, the absolute value of the preset difference can be set according to experiments or experience, and the embodiment of the application is not limited to this. Optionally, the electronic device includes an ambient brightness detection device, and the ambient brightness of the environment where the electronic device is located is periodically detected by the ambient brightness detection device, so as to realize monitoring of the ambient brightness.

S402, acquiring a second gear of the electrochromic device under the condition that the first preset condition is met.

The first preset condition includes at least one of: the interruption adjustment times of the electrochromic device are larger than a first threshold value, and abnormal power-down occurs in the last gear adjustment process of the electrochromic device.

The number of interrupt adjustment of the electrochromic device refers to the number of occurrences of the second gear adjustment signal received within the response time of the first gear adjustment signal. When an electrochromic device undergoes electrochemical oxidation reaction under the action of an externally applied electric field, a certain time is required for the electrochromic device to finally complete coloring or fading due to the limited ion expansion speed, and the time is called the response time of the electrochromic device. The response time of the first gear adjustment signal is the time required to complete the coloring or bleaching of the electrochromic device according to the first gear adjustment signal. For example, the time when the user triggers the first gear adjustment signal is 10:00:24, the response time of the first gear adjustment signal is 2 seconds, if the user is at 10:00:25, a second gear adjustment signal is triggered, an interrupt adjustment is indicated. In some embodiments, the electronic device is provided with a counter for counting the number of interrupt adjustment, and the value of the counter is increased by 1 when the electronic device detects that interrupt adjustment occurs once, so as to count the number of interrupt adjustment.

Further, the number of interrupt adjustment times of the electrochromic device refers to the number of occurrence times of the second gear adjustment signal received within the response time of the first gear adjustment signal in the current power-up process of the electronic device. That is, after the electronic device is powered on, the number of interrupt adjustment times counted in the last power-on process is set to 0, and then the number of interrupt adjustment times in the current power-on process is counted.

The first threshold is set experimentally or empirically and may be any value greater than 1 and less than 10, such as 2. In some embodiments, the electronic device reads a count value of a counter counting the number of times of the intermittent adjustment, compares the count value with a first threshold, and adjusts the operating parameter of the electrochromic device based on a true value of a current operating gear of the electrochromic device and a desired value set by a user if the count value is greater than the first threshold.

When the interrupt adjustment occurs, the electrochromic device has generated electrochemical oxidation-reduction reaction within the response time of the first gear adjusting signal, at this time, the actual gear of the electrochromic device has changed, however, after the second gear adjusting signal is received, the electrochromic device does not record the changed working gear, but adjusts according to the stored value and the expected value of the working gear of the electrochromic device before the gear adjusting signal is received, and because the stored value of the working gear of the electrochromic device before the gear adjusting signal is received deviates from the actual value of the current working gear of the electrochromic device, the problem of inaccurate gear adjustment exists. In the embodiment of the application, when the interrupt adjustment times are too many, the gear adjustment is performed based on the true value of the current working gear of the electrochromic device, so that the problems can be overcome, and the accuracy of the gear adjustment is improved.

Abnormal power-down of the electrochromic device in the last gear adjusting process means that the electrochromic device is powered down within the response time of the first gear adjusting signal, which may be caused by the failure of the electronic device, may be caused by the failure of the control module of the electrochromic device, or may be triggered by a user, for example, the user extinguishes the electronic device within the response time of the first gear adjusting signal. Because the electrochromic device has electrochemical oxidation-reduction reaction in the response time of the first gear adjusting signal, at this time, the actual gear of the electrochromic device has changed, and the stored value of the current working gear of the electrochromic device deviates from the actual value of the current working gear of the electrochromic device, and when the gear adjusting signal is subsequently received, if the gear adjustment is performed based on the stored value of the current working gear of the electrochromic device, the gear adjustment is not accurate enough. In the embodiment of the application, abnormal power-down occurs in the last gear adjustment process of the electrochromic device, and the gear adjustment is performed based on the true value of the current working gear of the electrochromic device, so that the problems can be overcome, and the accuracy of the gear adjustment is improved.

The second gear is used to characterize the true value of the current operating gear of the electrochromic device. The second gear is determined based on a second operating parameter of the electrochromic device that reflects the actual operating condition of the electrochromic device. Wherein the second gear may be obtained by the following procedure.

S402a, the current open circuit voltage of the electrochromic device is obtained.

The open circuit voltage of the electrochromic device, that is, the second operating parameter, refers to the voltage between the end of the first transparent conductive layer away from the power source and the end of the second transparent conductive layer away from the power source. Referring again to fig. 1, "V" in the diagram is the current open circuit voltage of the electrochromic device. Optionally, one end of the first transparent conductive layer far away from the power supply, and one end of the second transparent conductive layer far away from the power supply are connected in series with a voltage detection device, and the current open-circuit voltage of the electrochromic device is detected through the voltage detection device.

S402b, determining the current transmittance of the electrochromic device based on the current open-circuit voltage of the electrochromic device.

Transmittance refers to the ratio of the radiant energy projected through an object to the total radiant energy projected onto the object during the time that the incident light flux leaves from the illuminated or medium incident surface to the other surface.

In some embodiments, the electronic device determines a current transmittance of the electrochromic device based on the first mapping relationship and a current open circuit voltage of the electrochromic device. The first mapping relation comprises mapping relation between different open-circuit voltages and different transmittances of the electrochromic device. The first mapping may be obtained through a preliminary test, which may be a functional relationship between the open circuit voltage and the transmittance of the electrochromic device.

S402c, determining a second gear of the electrochromic device based on the current transmittance of the electrochromic device.

In some embodiments, the electronic device determines a second gear of the electrochromic device based on the second mapping relationship and the current transmittance of the electrochromic device.

The second mapping relation comprises mapping relations between different gears and different transmittances of the electrochromic device, and the transmittance corresponding to each gear can be a numerical value or a transmittance interval. In the above embodiment, it is mentioned that the gear of the electrochromic device is designed by a designer according to the minimum value and the maximum value of the optical property (such as transmittance) of the electrochromic device, so that the second mapping relationship between different gear and different transmittance is stored in the electronic device, and based on the second mapping relationship and the current transmittance of the electrochromic device, the true value of the current working gear of the electrochromic device can be determined. The following table-1 illustrates a second mapping relationship provided in an embodiment of the present application.

S403, based on the first gear and the second gear, adjusting the first working parameter of the electrochromic device to enable the working gear of the electrochromic device to reach the first gear.

In this embodiment, the first operating parameter is a control voltage applied to the electrochromic device, that is, an output voltage of the power module, which may be a constant voltage or a variable voltage. It should be noted that, the control voltage of the electrochromic device needs to be within the safe voltage range of the electrochromic device to avoid the electrochromic device from being burned.

In some embodiments, S403 may include the following sub-steps: acquiring an absolute value of a difference value between the first gear and the second gear; determining a target control voltage for the electrochromic device based on the absolute value of the difference; and applying a target control voltage to the electrochromic device so that the open-circuit voltage of the electrochromic device reaches the open-circuit voltage corresponding to the first gear.

The open circuit voltage corresponding to the first gear may be determined based on the first mapping relationship and the second mapping relationship, which are not described herein. In this embodiment of the present application, the electronic device may determine, based on a mapping relationship between an absolute value of a gear difference and a control voltage, the control voltage corresponding to the absolute value of the difference between the first gear and the second gear as the target control voltage, and then apply the target control voltage to the electrochromic device. In the process of applying the target control voltage, the electronic equipment monitors the open-circuit voltage of the electrochromic device in real time, and stops applying the target control voltage after monitoring that the open-circuit voltage of the electrochromic device reaches the open-circuit voltage corresponding to the first gear, so that gear adjustment of the electrochromic device is realized.

It should be noted that, after the electronic device completes the gear adjustment based on the first gear and the second gear, the number of interrupt adjustment times needs to be set to 0, so as to avoid the electronic device from performing the gear adjustment according to the first gear and the second gear each time, and save the power consumption of the electronic device.

In summary, in the technical solution provided in the embodiment of the present application, under the condition that the gear adjustment signal is received and the condition that the first preset condition is met is monitored, the gear adjustment is performed on the electrochromic device based on the actual value of the current working gear of the electrochromic device, instead of performing the gear adjustment on the electrochromic device based on the stored value of the current working gear of the electrochromic device, because the number of times of interrupt adjustment is excessive or abnormal power down occurs in the last gear adjustment process, there is usually a deviation between the stored value of the current working gear of the electrochromic device and the actual value, if the gear adjustment is performed on the electrochromic device based on the stored value of the current working gear of the electrochromic device, the gear adjustment result is not accurate enough, and in the embodiment of the present application, the gear adjustment is performed on the electrochromic device based on the actual value of the current working gear of the electrochromic device, so that the above problem can be overcome, thereby improving the accuracy of the gear adjustment.

Referring to fig. 6, a flowchart of a control method of an electrochromic device according to an embodiment of the present application is shown. The method is applied to an electronic device including an electrochromic device, and includes the following process.

S601, after a gear adjustment signal for an electrochromic device is acquired, a first gear is acquired based on the gear adjustment signal.

The first gear is used to characterize the desired value of the operating gear of the electrochromic device. The explanation of S601 may be referred to as S401, and will not be described here.

S602, acquiring a third gear of the electrochromic device under the condition that the first preset condition is not met.

The third gear is used to characterize the stored value of the current operating gear of the electrochromic device. In some embodiments, the electronic device includes a gear field of the electrochromic device, the value of the gear field being the third gear, and the electronic device determines the third gear of the electrochromic device by reading the value of the gear field. In other embodiments, the electronic device includes a shift control bar of the electrochromic device that includes an adjustable control, the position of the adjustable control on the shift control bar corresponds to a third gear, and the electronic device determines the third gear based on the position by reading the position of the adjustable control on the shift control bar.

In the embodiment of the application, when it is detected that the first preset condition is not met, that is, the interruption adjustment frequency is smaller than or equal to a first threshold value, and when abnormal power-down does not occur in the last gear adjustment process of the electrochromic device, gear adjustment is performed based on the first gear and the third gear.

Because the deviation between the actual value and the stored value of the current working gear of the electrochromic device is usually smaller under the condition that the first preset condition is not met, the gear adjustment is performed based on the stored value of the current working gear of the electrochromic device, the gear adjustment result is also more accurate, and the process of acquiring the stored value is simpler than that of the actual value, so that the gear adjustment is performed based on the stored value of the current working gear of the electrochromic device under the condition that the first preset condition is not met, and the power consumption of the electronic equipment can be saved on the premise of obtaining more accurate gear adjustment result.

And S603, adjusting the first operating parameter of the electrochromic device based on the first gear and the third gear so that the operating gear of the electrochromic device reaches the first gear.

In some embodiments, S603 may include the following process: acquiring an absolute value of a difference value between the first gear and the third gear; determining a first control voltage of the electrochromic device based on an absolute value of a difference between the first gear and the third gear; and applying a first control voltage to the electrochromic device so that the open-circuit voltage of the electrochromic device reaches the open-circuit voltage corresponding to the first gear.

The open circuit voltage corresponding to the first gear may be determined based on the first mapping relationship and the second mapping relationship, which are not described herein. In this embodiment of the present application, the electronic device may determine, based on a mapping relationship between an absolute value of a gear difference and a control voltage, the control voltage corresponding to the absolute value of the difference between a first gear and a third gear as the first control voltage, and then apply the first control voltage to the electrochromic device. In the process of applying the first control voltage, the electronic equipment monitors the open-circuit voltage of the electrochromic device in real time, and after the open-circuit voltage of the electrochromic device reaches the open-circuit voltage corresponding to the first gear, the electronic equipment stops applying the second control voltage, so that the gear adjustment of the electrochromic device is realized.

In summary, in the technical solution provided in the embodiment of the present application, when it is monitored that the first preset condition is not satisfied, that is, the number of times of interrupt adjustment is less than or equal to the first threshold value, and when no abnormal power down occurs in the last gear adjustment process of the electrochromic device, the gear adjustment is performed based on the stored value of the current working gear of the electrochromic device.

In the embodiment of the application, the electronic device can calibrate the electrochromic device, so that the deviation between the actual value and the stored value of the current working gear of the electrochromic device is as small as possible, and after receiving the gear adjusting signal, the electronic device can adjust the gear based on the stored value of the electrochromic device, and the power consumption of the electronic device can be saved on the premise of obtaining a relatively accurate gear adjusting result. In some embodiments, the electronic device calibrates the electrochromic device if it is monitored that the second preset condition is met.

The second preset condition includes at least one of: the complete adjustment times of the electrochromic device after the appointed time are larger than a second threshold value, the continuous power-down time of the electrochromic device is larger than the appointed time, and the electronic equipment receives a calibration instruction for the electrochromic device.

The designated time refers to the completion time of the last calibration procedure of the electrochromic device. The complete adjustment times are used to characterize the number of occurrences of the electrochromic device not receiving the second gear adjustment signal within the response time of the first gear adjustment signal. Illustratively, the time at which the user triggers the first gear adjustment signal is 10:00:24, the response time of the first gear adjustment signal is 2 seconds, if the user is at 10:00:24-10:00:26, no second gear adjustment signal is received during this period, a complete adjustment is indicated. The second threshold is set experimentally or empirically, and is illustratively 100. In this embodiment of the present application, after the last calibration, if the number of gear adjustments made to the electrochromic device by the user is enough, the deviation between the actual value and the stored value of the current working gear of the electrochromic device may be large, and at this time, the electrochromic device needs to be calibrated to improve the accuracy of the subsequent gear adjustment. In this embodiment, the vehicle may detect whether the number of complete adjustments is greater than the second threshold after the electrochromic device is powered up, or may detect whether the number of complete adjustments is greater than the second threshold after the number of complete adjustments is updated.

In other possible embodiments, the electronic device calibrates the electrochromic device after a preset period of time after the specified time. The preset time period may be set according to experiments or experience, which is not limited in the embodiment of the present application. For example, the preset duration is 15 days. The specified duration may be set experimentally or empirically, such as for 1 month. The electrochromic device may decay naturally when powered down for a long time, and at this time, the deviation between the actual value and the stored value of the current working gear of the electrochromic device may be large, so that calibration of the electrochromic device is required to improve the accuracy of subsequent gear adjustment. In this embodiment, the vehicle may monitor, by a timer, whether the length of time from the current time of the last calibration time for the electrochromic device has reached a preset length of time.

The user can trigger a calibration instruction for the electrochromic device according to the self requirement, and then the electronic equipment calibrates the electrochromic device so as to improve the accuracy of subsequent gear adjustment. In some embodiments, a calibration control is displayed on the central control screen, and if a trigger signal for the calibration control is received, a calibration instruction for the electrochromic device is received. In other embodiments, the user issues a voice signal and receives a calibration instruction when the electronic device recognizes that the voice signal includes the name of the electrochromic device and a specified keyword of "calibration". In some embodiments, the electronic device receives the calibration instruction after receiving a specified trigger signal for the entity control. In this embodiment, the vehicle is monitored for receipt of a trigger calibration command for the electrochromic device, either with the entire vehicle powered up or with the electrochromic device powered up.

The calibration procedure for electrochromic devices is described below in connection with fig. 7. The calibration procedure for electrochromic devices may include the following procedure.

S701, controlling the electrochromic device to perform an m-wheel gear adjustment process.

m is an integer greater than 1. In some embodiments, the value of m may be determined from a stored value of the current operating range of the electrochromic device and a total range value.

In some embodiments, the electronics control the electrochromic device for step-by-step adjustment. Specifically, the electronic device acquires a stored value of a current working gear, then gradually increases the working gear of the electrochromic device by taking the stepping length as a unit length (for example, 1 gear), and gradually decreases the working gear of the electrochromic device by taking the stepping length as a unit length (for example, 1 gear) after the working gear of the electrochromic device reaches a gear maximum value until the working gear of the electrochromic device is a gear minimum value.

By way of example, the total gear of the electrochromic device is 7 gears, the stored value of the current working gear is 4 gears, and then the electronic device sequentially adjusts the working gear of the electrochromic device to 5 gears, 6 gears, 7 gears, 6 gears, 5 gears, 4 gears, 3 gears, 2 gears and 1 gears, thereby realizing the m-wheel gear adjustment process.

In the gear adjustment process of each gear in the m-wheel gear adjustment process, the electrochromic device determines the expected gear in the gear adjustment process of each gear, then determines the second control voltage of the electrochromic device according to the absolute value of the difference between the stored value of the current working gear and the expected gear, applies the second control voltage to the electrochromic device, monitors the open-circuit voltage of the electrochromic device in real time in the process of applying the second control voltage, and stops applying the second control voltage after the open-circuit voltage of the electrochromic device is monitored to reach the open-circuit voltage corresponding to the expected gear, so that the gear adjustment of the electrochromic device is realized.

In the m-wheel range adjustment, there is at least one desired range of the m-wheel range adjustment as a range minimum value, and at least one desired range of the m-wheel range adjustment as a range maximum value. In the gear adjusting process in which the expected gear is the minimum value of the gear and in the adjusting process in which the expected gear is the maximum value of the gear, the end condition is that the open-circuit voltage of the electrochromic device is constant.

Specifically, the electronic apparatus determines a minimum value of the transmittance of the electrochromic device according to a smaller value of the boundary values of the electrochromic device, and determines a maximum value of the transmittance of the electrochromic device according to a larger value of the boundary values of the electrochromic device.

S703, dividing the working gear of the electrochromic device into n gears based on the minimum value and the maximum value of the transmittance of the electrochromic device to obtain a third mapping relation.

n is an integer greater than 1, and the value of n is preset, which is the total gear number before the electrochromic device is calibrated, for example, n is 12. The third mapping relation comprises mapping relation between different gears and different transmittances of the electrochromic device after calibration.

The electronic equipment can determine the change range of the transmittance based on the minimum value and the maximum value of the transmittance of the electrochromic device, and then evenly divide the change range to obtain the corresponding transmittance interval or transmittance value of each grade.

And S704, determining a target gear based on the transmittance before the calibration of the electrochromic device and the third mapping relation.

The electronic device may determine the transmittance of the electrochromic device before calibration based on the first mapping relationship and the stored value of the working gear before calibration of the electrochromic device, and then find the third mapping relationship to determine the target gear.

And S705, adjusting the first working parameter of the electrochromic device to enable the working gear of the electrochromic device to reach the target gear.

The electronic equipment obtains the absolute value of the difference between the minimum gear and the target gear; determining a third control voltage for the electrochromic device based on an absolute value of a difference between the minimum gear and the target gear; and applying a third control voltage to the electrochromic device so that the open-circuit voltage of the electrochromic device reaches the open-circuit voltage corresponding to the target gear.

The open circuit voltage corresponding to the target gear may be determined based on the second mapping relationship and the third mapping relationship, which are not described herein. In the embodiment of the present application, the electronic device may determine, based on a mapping relationship between the absolute value of the gear difference and the control voltage, the control voltage corresponding to the absolute value of the difference between the minimum gear and the target gear as the third control voltage, and then apply the third control voltage to the electrochromic device. In the process of applying the third control voltage, the electronic equipment monitors the open-circuit voltage of the electrochromic device in real time, and stops applying the third control voltage after monitoring that the open-circuit voltage of the electrochromic device reaches the open-circuit voltage corresponding to the target gear, so that gear adjustment of the electrochromic device is realized.
