[0078] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0079] In the embodiments of the present application, the term "and / or" describes the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0080] It should be noted that the multiple involved 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, the words "first", "second", etc. are only used for the purpose of distinguishing the description, and cannot be understood as indicating or implying relative importance, nor can they be understood as indicating or implying an order.

[0081] It is very costly to add or modify dimming glass in existing vehicles, and technicians are required to install relevant control devices for adjusting the transmittance of dimming glass. For example, touch buttons or physical buttons are added to the vehicle so that users can adjust the transmittance of dimming glass through the added touch buttons or physical buttons. This method requires modifying the existing window system of the vehicle, or even modifying the circuit structure of the existing window system. The circuit structures of window systems provided by different manufacturers are different. In order to add dimming glass, each manufacturer needs to modify the circuit structure of the window system, which increases the manufacturer's design, production and management costs.

[0082] In view of this, the embodiments of the present application provide a method for adjusting the light 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.

[0083] 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 also 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.

[0084] Usually, the transmittance of the dimming glass can be adjusted by any of the control methods of electric control, temperature control, light control, and voltage control. Generally speaking, the transmittance of the dimming glass is adjusted by electric control. For example, the drive circuit can adjust the transmittance of the dimming glass by voltage control or current control. The drive circuit can adjust the transmittance of the dimming glass by adjusting the driving voltage of the dimming glass.

[0085] Figure 1 An exemplary vehicle window system is shown, 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.

[0086] In a possible implementation, the lifting and lowering adjustment button may be implemented as a physical button, such as a mechanical button or a touch button.

[0087] In some examples, the lifting and lowering adjustment button may include an raising button and a lowering button. The user may trigger the control of the window glass rising by pressing the raising button. The user may trigger the control of the window glass lowering by pressing the lowering button. In this example, the lifting and lowering operation receiving circuit may generate a window raising signal when the lifting and lowering adjustment button is pressed. The lifting and lowering operation receiving circuit may generate a window lowering signal when the lowering adjustment button is pressed. The window raising signal represents a signal for controlling the window to rise. The window lowering signal represents a signal for controlling the window to lower.

[0088] In other examples, the user can trigger the control of the window glass rising by lifting the lifting adjustment button. The user can trigger the control of the window glass falling by pressing the lifting adjustment button. In this example, the lifting operation receiving circuit can generate a window rising signal when the lifting adjustment button is lifted. The lifting operation receiving circuit can generate a window falling signal when the falling adjustment button is pressed.

[0089] In another possible implementation, the lifting button can be implemented as a virtual button. The user can trigger the lifting and lowering of the window glass through the virtual button. In this embodiment, the lifting operation receiving circuit can be implemented as a display system in the vehicle. The display system can display the virtual button through the display and detect the window control operation triggered by the user. The display system can generate a window raising signal when detecting that the user triggers the window raising control operation. The display system can generate a window lowering signal when detecting that the user triggers the window lowering control operation.

[0090] The specific structure and form of the lifting operation receiving circuit are not specifically limited in the embodiments of the present application. Those skilled in the art should understand that any mechanical and circuit structure that can generate a window raising signal when a user triggers a window raising control operation, and generate a window lowering signal when a user triggers a window lowering control operation, can be used as the lifting operation receiving circuit mentioned in the embodiments of the present application.

[0091] The lifting and lowering operation receiving circuit can be coupled to the control device via a signal line. In some examples, the lifting and lowering operation receiving circuit is coupled to the control device via a signal line M0, such as Figure 2 The window up signal can be a rectangular signal, such as Figure 2 The signal S1 shown in FIG. 1 is a rectangular signal, such as Figure 2 The signal S2 shown in FIG. 1 , wherein the low level of the window up signal is equal to the high level of the window down signal.

[0092] The control device can detect the window up signal or the window down signal by detecting the level change of the rectangular signal on the signal line M0. The control device can control the window glass to rise in response to detecting the window up signal. The control device can control the window glass to fall in response to detecting the window down signal.

[0093] In other examples, such as Figure 3 As shown, the lifting operation receiving circuit can be coupled to the control device through 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, the window raising signal and the window lowering signal can both be pulse signals.

[0094] 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 a pulse signal on the first signal line M1.

[0095] 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 a pulse signal on the second signal line M2.

[0096] The aforementioned control device may be any existing control device capable of realizing the aforementioned functions or capabilities. This application embodiment does not specifically limit this. For example, please refer to Figure 1 The control device may include a first controller and a driving structure. The first controller is coupled to the lifting operation receiving circuit and is used to detect a window raising signal or a window lowering signal. The first controller may control the driving structure to raise the window glass in response to detecting the window raising signal. The first controller may control the driving structure to lower the window glass in response to detecting the window lowering signal.

[0097] Of course, in actual application scenarios, if the window glass is at the preset highest position, the window system will not respond to the user-triggered operation of controlling the window glass to rise. Similarly, if the window glass is at the preset lowest position, the window system will not respond to the user-triggered operation of controlling the window glass to fall.

[0098] In order to replace the window glass with dimming glass and adjust the light transmittance of the dimming glass without changing the existing circuit structure or mechanical structure of the window system. Figure 4The vehicle window system may include a vehicle window glass, a lifting operation receiving circuit and a control device. The vehicle window glass is a dimming glass. The lifting and lowering control of the dimming glass by the vehicle window system can refer to the above-mentioned related introduction, which will not be repeated here.

[0099] The present application also provides a light transmittance adjustment device for adjusting the light transmittance of dimming glass. The control device in the vehicle window system may also include the light transmittance adjustment device provided by the present application.

[0100] In some examples, the lifting 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.

[0101] In some other examples, the lifting operation receiving circuit is coupled to the first controller through the aforementioned signal line M1 and the aforementioned signal line M2. In this case, the transmittance adjustment device can be coupled to the signal line M1 and coupled to the signal line M2. The transmittance adjustment device can detect whether the window raising signal is received by detecting whether the first signal line M1 has a pulse signal. The transmittance adjustment device can detect whether the window lowering signal is received by detecting whether the first signal line M2 has a pulse signal.

[0102] The transmittance adjustment device can execute the transmittance adjustment method for the vehicle window provided in the embodiment of the present application, or the second controller can execute the transmittance adjustment method for the vehicle window provided in the embodiment of the present application. Figure 5 As shown, the light transmittance adjustment method of the vehicle window provided in the embodiment of the present application may include the following steps:

[0103] S501, continuously receiving a plurality of target signals, wherein the target signals are used to control the lifting and lowering of the vehicle window.

[0104] In specific implementation, the target signal may be any one of the window up signal and the 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 the signal line coupled between the lifting operation receiving circuit and the first controller.

[0105] S502: Generate a transmittance adjustment signal for the dimming glass of the vehicle window according to the reception time of the multiple target signals.

[0106] In a specific implementation, after continuously receiving multiple target signals, the transmittance adjusting device may perform the operation in step S502. The reception time between the multiple target signals continuously received by the transmittance adjusting device meets the preset condition, which may reflect that the user triggers the operation of adjusting the dimming glass, so that the transmittance adjusting device may adjust the transmittance of the dimming glass.

[0107] The transmittance adjustment method provided in the embodiment of the present application reuses the window up signal or the window down signal to determine whether the user triggers the transmittance adjustment operation. It can be seen that in the method provided by the present application, the user can use the lifting and lowering adjustment button in the window system to trigger the adjustment of the transmittance of the dimming glass. Without changing the existing circuit structure of the window system, the application of dimming glass in the window system is realized at a lower cost.

[0108] 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 a position signal of the vehicle window provided by the first controller, and the position signal represents the current position of the vehicle window.

[0109] 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.

[0110] Alternatively, the aforementioned preset condition may be that the position of the vehicle window is at the maximum raised position. The light transmittance adjustment device may perform the operation in step S502 when the position of the vehicle window is at the maximum raised position.

[0111] In a possible implementation, in the method for adjusting the transmittance of a vehicle window provided in an embodiment of the present application, in the operation of generating the transmittance adjustment signal of the dimming glass of the vehicle window according to the reception time of the multiple target signals by the transmittance adjustment device, the transmittance adjustment signal of the dimming glass of the vehicle window can be generated according to the reception time difference of the multiple target signals. Optionally, if the reception time difference of the multiple target signals is less than or equal to the element and time difference threshold, the transmittance adjustment device can generate the transmittance adjustment signal of the dimming glass of the vehicle window.

[0112] Optionally, the number of the continuous multiple target signals may be an integer greater than or equal to 2. The following is introduced by taking the number of the multiple target signals being 2 as an example. The multiple target signals may include a continuous first pulse signal and a second pulse signal.

[0113] 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-raising signals.

[0114] Optionally, the transmittance adjustment device may only detect the window up signal. In this case, the user may trigger the window up control operation multiple times in a row to trigger the light transmittance adjustment of the light-transmitting glass. The first pulse signal and the second pulse signal are respectively the first window up signal and the second window up signal. Figure 6 Multiple window up signals are shown.

[0115] In some examples, the reception time difference of the plurality of target signals may be the duration between the rising edge t1 of the first window up signal and the 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.

[0116] In some other examples, the reception time difference of the plurality of target signals may be the duration between the falling edge t2 of the first window up signal and the 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.

[0117] In some other examples, the reception time difference of the plurality of target signals may be the duration between the rising edge t1 of the first window up signal and the falling edge t4 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 falling edge t4 of the second window up signal being less than or equal to the time difference threshold.

[0118] In some other examples, the transmittance adjustment device can 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 falling edge t4 of the second window up signal being less than or equal to the time difference threshold.

[0119] In another possible scenario, both the first pulse signal and the second pulse signal are signals for controlling the window to be lowered, that is, both are window lowering signals.

[0120] Optionally, the transmittance adjustment device may only detect the window lowering signal. In this case, the user triggers the window lowering control operation multiple times within a preset time period to trigger the adjustment of the transmittance of the light-transmitting glass. The first pulse signal and the second pulse signal are the first window lowering signal and the second window lowering signal, respectively. Figure 7 Multiple window down signals are shown.

[0121] In some examples, the reception time difference of the plurality of target signals may be the duration between the rising edge t1 of the first window down signal and the rising edge t3 of the second window down 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 down signal and the rising edge t3 of the second window down signal being less than or equal to the time difference threshold.

[0122] In some other examples, the reception time difference of the plurality of target signals may be the duration between the falling edge t2 of the first window down signal and the rising edge t3 of the second window down signal.

The maximum transmittance gear is gear N, and the minimum transmittance gear is gear 1. If the transmittance adjustment device determines that the current transmittance gear is gear 1, the transmittance adjustment device can determine gear N as the target transmittance gear.
