[0081] To make the objectives, technical solutions, and advantages of this application more clear, this application will be further described in detail below with reference to the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0082] In the embodiments of this application, the term "and / or" describes the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0083] It should be noted that the term "multiple" in the embodiments of the present application refers to two or more. In addition, it should be understood that in the description of the embodiments of the present application, terms such as "first" and "second" are used only for the purpose of distinguishing descriptions and should not be understood as indicating or implying relative importance or order.

[0084] Adding or retrofitting dimming glass to existing vehicles is costly, requiring technicians to install controls to adjust the transmittance of the glass. For example, a touchscreen or physical button could be added to the vehicle, allowing the user to adjust the transmittance of the glass. This approach requires modifying the vehicle's existing window system, and even revising the existing window system's circuit structure. Since window systems from different manufacturers have different circuit structures, adding dimming glass requires each manufacturer to modify the window system's circuit structure, increasing design, production, and management costs.

[0085] In view of this, the embodiments of the present application provide a method for adjusting the transmittance of a vehicle window and related equipment, which can reduce the cost of applying dimming glass to the vehicle window, do not change the existing circuit structure of the vehicle window system, and have high compatibility.

[0086] The application scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. It is known to those skilled in the art that, with the emergence of new application scenarios, the technical solutions provided in the embodiments of the present application are equally applicable to similar technical problems. In the description of the present application, unless otherwise specified, the meaning of "multiple" is two or more. In the embodiments of the present application, "coupling" refers to the direct or indirect combination of two components with each other.

[0087] Typically, the transmittance of switchable glass can be adjusted by any of several control methods: electrical control, temperature control, light control, or voltage control. Generally, the transmittance of switchable glass is adjusted electrically. For example, the drive circuit can adjust the transmittance of the switchable glass through voltage control or current control. The drive circuit can adjust the transmittance of the switchable glass by adjusting the drive voltage of the switchable glass.

[0088] Fig. 1 exemplarily shows a vehicle window system, which may include a vehicle window glass, a lifting operation receiving circuit, and a control device. The lifting operation receiving circuit may include a lifting adjustment button.

[0089] In a possible implementation, the lift adjustment button may be implemented as a physical button, such as a mechanical button or a touch button.

[0090] In some examples, the lift adjustment buttons may include an up button and a down button. A user may trigger the window glass to rise by pressing the up button. A user may trigger the window glass to fall by pressing the down button. In this example, the lift operation receiving circuit may generate a window-up signal when the lift adjustment button is pressed. The lift operation receiving circuit may generate a window-down signal when the down adjustment button is pressed. The window-up signal represents a signal for controlling the window to rise. The window-down signal represents a signal for controlling the window to fall.

[0091] In other examples, a user can trigger the window glass to rise by lifting a lift adjustment button. A user can trigger the window glass to fall by pressing a lift adjustment button. In this example, the lift operation receiving circuit can generate a window-raising signal when the lift adjustment button is lifted. The lift operation receiving circuit can generate a window-lowering signal when the lift adjustment button is pressed.

[0092] In another possible implementation, the lift button can be implemented as a virtual button. Users can use this virtual button to trigger and control the raising and lowering of the vehicle window glass. In this embodiment, the lift operation receiving circuit can be implemented as a display system in the vehicle. The display system can display the virtual button on a display and detect user-triggered window control operations. The display system can generate a window-up signal when it detects a user-triggered window-up control operation. The display system can also generate a window-down signal when it detects a user-triggered window-down control operation.

[0093] The embodiments of this application do not specifically limit the specific structure and form of the lifting operation receiving circuit. Those skilled in the art will appreciate that any mechanical or circuit structure capable of generating a window-up signal when a user triggers a window-up control operation, and generating a window-down signal when a user triggers a window-down control operation, may serve as the lifting operation receiving circuit mentioned in the embodiments of this application.

[0094] The lift operation receiving circuit can be coupled to the control device via a signal line. In some examples, the lift operation receiving circuit is coupled to the control device via a signal line M0, as shown in Figure 2. The window-up signal can be a rectangular signal, such as signal S1 shown in Figure 2. The window-down signal can be a rectangular signal, such as signal S2 shown in Figure 2. The low level of the window-up signal is equal to the high level of the window-down signal.

[0095] The control device can detect the window-up signal or window-down signal by detecting the level change of the rectangular signal on signal line M0. In response to detecting the window-up signal, the control device can control the window glass to rise. In response to detecting the window-down signal, the control device can control the window glass to fall.

[0096] In other examples, as shown in FIG3 , the raising / lowering operation receiving circuit can be coupled to the control device via two signal lines, wherein the two signal lines include a first signal line M1 and a second signal line M2. The first signal line M1 can be used to transmit a window raising signal. The second signal line M2 can be used to transmit a window lowering signal. In this example, both the window raising signal and the window lowering signal can be pulse signals.

[0097] The control device can detect whether the window raising signal is received by detecting whether there is a pulse signal on the first signal line M1. The control device can control the window glass to rise in response to detecting the pulse signal on the first signal line M1.

[0098] The control device can detect whether the window lowering signal is received by detecting whether there is a pulse signal on the second signal line M2. The control device can control the window glass to lower in response to detecting the pulse signal on the second signal line M2.

[0099] The aforementioned control device can be any existing control device that can achieve the above-mentioned functions or capabilities. The embodiments of the present application do not specifically limit this. For example, please refer to Figure 1 again. The control device may include a first controller and a drive structure. The first controller is coupled to the lifting operation receiving circuit and is used to detect a window rising signal or a window falling signal. In response to detecting the window rising signal, the first controller can control the drive structure to raise the window glass. In response to detecting the window falling signal, the first controller can control the drive structure to lower the window glass.

[0100] Of course, in actual application scenarios, if the window glass is in the preset uppermost position, the window system will not respond to the user-triggered control of the window glass rising operation. Similarly, if the window glass is in the preset lowermost position, the window system will not respond to the user-triggered control of the window glass falling operation.

[0101] To achieve the goal of replacing vehicle window glass with dimming glass and adjusting the transmittance of the dimming glass without changing the existing circuit or mechanical structure of the vehicle window system, an embodiment of the present application provides a vehicle window system. See Figure 4 . The vehicle window system may include a vehicle window glass, a lifting and lowering operation receiving circuit, and a control device. The vehicle window glass is dimming glass. The vehicle window system's control of raising and lowering the dimming glass can be found in the aforementioned description and will not be further elaborated here.

[0102] The present application also provides a light transmittance adjustment device for adjusting the light transmittance of the switchable glass. The control device in the vehicle window system may also include the light transmittance adjustment device provided by the present application.

[0103] In some examples, the raising / lowering operation receiving circuit is coupled to the first controller via a signal line M0. The transmittance adjustment device is coupled to the signal line M0. In this case, the transmittance adjustment device can detect the window raising signal or the window lowering signal by detecting the level change of the rectangular signal on the signal line M0.

[0104] In other examples, the raising / lowering operation receiving circuit is coupled to the first controller via the aforementioned signal line M1 and the aforementioned signal line M2. In this case, the transmittance adjustment device can be coupled to both signal line M1 and signal line M2. The transmittance adjustment device can detect whether a window raising signal has been received by detecting whether a pulse signal is present on the first signal line M1. The transmittance adjustment device can detect whether a window lowering signal has been received by detecting whether a pulse signal is present on the first signal line M2.

[0105] The transmittance adjustment device can execute the transmittance adjustment method for a vehicle window provided in an embodiment of the present application, or the second controller can execute the transmittance adjustment method for a vehicle window provided in an embodiment of the present application. As shown in FIG5 , the transmittance adjustment method for a vehicle window provided in an embodiment of the present application can include the following steps:

[0106] S501, continuously receiving a plurality of target signals, wherein the target signals are used to control the lifting and lowering of the vehicle window.

[0107] In a specific implementation, the target signal may be any one of a window up signal and a window down signal corresponding to the window. The transmittance adjustment device may detect whether there is a window up signal or a window down signal on a signal line coupled between the lifting operation receiving circuit and the first controller.

[0108] S502 : Generate a transmittance adjustment signal for the dimming glass of the vehicle window according to the reception time of the multiple target signals.

[0109] In a specific implementation, after the transmittance adjustment device continuously receives multiple target signals, it can perform the operation in step S502. If the reception time between the multiple target signals continuously received by the transmittance adjustment device satisfies a preset condition, it can indicate that the user has triggered an operation to adjust the dimming glass, and the transmittance adjustment device can adjust the transmittance of the dimming glass.

[0110] The transmittance adjustment method provided in this embodiment reuses the window-up signal or window-down signal to determine whether the user has triggered the transmittance adjustment operation. This method allows the user to adjust the transmittance of the dimming glass using the window system's lift adjustment buttons. This method allows the application of dimming glass to the window system without changing the existing circuit structure of the window system, at a relatively low cost.

[0111] In one possible application scenario, the transmittance adjustment device can execute the transmittance adjustment method provided in the above embodiment after the vehicle window system is started. In another possible application scenario, the transmittance adjustment device can obtain the position of the vehicle window, and when the position of the vehicle window meets the preset conditions, generate a transmittance adjustment signal for the dimming glass of the vehicle window according to the reception time of the multiple target signals. Optionally, the transmittance adjustment device may also include a position sensor, which can be used to detect the position of the vehicle window. Or the transmittance adjustment device can obtain the position of the vehicle window from the first controller. For example, the transmittance adjustment device can receive the position signal of the vehicle window provided by the first controller, and the position signal represents the current position of the vehicle window.

[0112] Optionally, the preset condition may be that the distance between the position of the vehicle window and the maximum raised position of the vehicle window satisfies a preset distance condition. The transmittance adjustment device may perform the operation in step S502 when the distance between the position of the vehicle window and the maximum raised position of the vehicle window satisfies the preset distance condition.

[0113] Alternatively, the preset condition may be that the vehicle window is at the maximum raised position. The transmittance adjustment device may perform the operation in step S502 when the vehicle window is at the maximum raised position.

[0114] In one possible embodiment, in the vehicle window transmittance adjustment method provided in an embodiment of the present application, the transmittance adjustment device may generate the transmittance adjustment signal for the vehicle window's dimming glass based on the reception times of the multiple target signals. The transmittance adjustment signal for the vehicle window's dimming glass may be generated based on the reception time difference between the multiple target signals. Optionally, the transmittance adjustment device may generate the transmittance adjustment signal for the vehicle window's dimming glass if the reception time difference between the multiple target signals is less than or equal to a time difference threshold.

[0115] Optionally, the number of the consecutive target signals may be an integer greater than or equal to 2. The following description is made by taking the number of the consecutive target signals as 2 as an example. The multiple target signals may include a consecutive first pulse signal and a second pulse signal.

[0116] In a possible scenario, the first pulse signal and the second pulse signal are both signals for controlling the window to rise, that is, both are window-up signals.

[0117] Alternatively, the transmittance adjustment device may detect only the window-up signal. In this case, the user can trigger the window-up control operation multiple times to adjust the transmittance of the translucent glass. The first pulse signal and the second pulse signal are the first window-up signal and the second window-up signal, respectively. Figure 6 illustrates multiple window-up signals.

[0118] In some examples, the reception time difference between the multiple target signals may be the duration between a rising edge t1 of the first window-up signal and a rising edge t3 of the second window-up signal. The transmittance adjustment device may generate a transmittance adjustment signal for the dimming glass of the vehicle window based on the duration between the rising edge t1 of the first window-up signal and the rising edge t3 of the second window-up signal being less than or equal to the time difference threshold.

[0119] In other examples, the reception time difference between the multiple target signals may be the duration between a falling edge t2 of the first window-up signal and a rising edge t3 of the second window-up signal. The transmittance adjustment device may generate a transmittance adjustment signal for the dimming glass of the vehicle window based on the duration between the falling edge t2 of the first window-up signal and the rising edge t3 of the second window-up signal being less than or equal to the time difference threshold.

[0120] In yet other examples, the reception time difference between the plurality of target signals may be the duration between a rising edge t1 of the first window-up signal and a falling edge t4 of the second window-up signal.
