Description

TECHNICAL FIELD

[0001] The utility model relates to but are not limited to data processing technical field, especially, a kind of light modulation system of vehicle window glass and vehicle. BACKGROUND

[0002] With the continuous development of various control technologies, the control of vehicle is also more and more mature, and the user's expectation for vehicle is also higher and higher.

[0003] At present, considering the demand of privacy, the user will paste dark car film on the window. However, the dark car film will cause unclear vision at night, and the user experience is low. UTILITY MODEL CONTENT

[0004] Therefore, the utility model embodiment provides at least a kind of light modulation system of vehicle window glass and vehicle. The light modulation system can adjust the light of vehicle window glass, avoid the discomfort caused by too bright or too dark ambient light, and improve user experience.

[0005] The technical scheme of the utility model embodiment is as follows:

[0006] In a first aspect, the utility model provides a light modulation system of vehicle window glass, which comprises a light modulation controller, a light sensor and a target vehicle window glass. The target vehicle window glass is a light-adjustable vehicle window glass. The target vehicle window glass comprises a first glass, a second glass and a light modulation film between the first glass and the second glass. The input end of the light modulation controller is connected with the light sensor, and the output end of the light modulation controller is connected with the light modulation film.

[0007] As can be seen, the light modulation system comprises a light modulation controller, a light sensor and a target vehicle window glass. Since the target vehicle window glass is a light-adjustable vehicle window glass, the input end of the light modulation controller is connected with the light sensor, and the output end of the light modulation controller is connected with the light modulation film. In this way, the light modulation controller can adjust the brightness based on the light data detected by the light sensor. Thus, first, when the ambient light brightness is too high, the light sensor can detect a large ambient brightness, and the light modulation controller can adjust the light transmittance of the light modulation film to reduce the light transmittance and improve the user's experience of glare. Second, when the ambient brightness is low, the light transmittance can be increased to improve the user's vision. Third, when the ambient brightness is in a normal state, the light transmittance can also be adjusted to a set value to ensure the user's privacy. Thus, the discomfort caused by too bright or too dark ambient light is avoided, and the user experience is improved.

[0008] In some implementations, the light modulation system further comprises a camera, and the output end of the camera is connected with the input end of the light modulation controller. Alternatively, the light modulation system further comprises a camera and a host controller, and the camera is connected with the light modulation controller through the host controller.

[0009] It can be seen that the dimming system can further include a camera, and the camera is connected with the dimming controller, so that the dimming controller can be controlled based on the image detected by the camera. The camera can also be connected with the dimming controller through the main control to control the dimming controller, thereby improving the intelligence of the dimming process.

[0010] For example, the camera can detect the user's line of sight, so as to determine whether to activate the dimming function based on the user's line of sight. For example, when the user's line of sight is detected to be directed to the target window glass, an electrical signal is sent to the dimming controller to activate the dimming function of the dimming controller. In this way, the intelligence of the dimming process is improved, and when the line of sight is not directed to the target window glass, the dimming function of the dimming controller is cancelled, thereby avoiding waste of resources and improving the utilization efficiency of resources.

[0011] In some implementations, the dimming system further includes a touch screen, and an output end of the touch screen is connected with an input end of the dimming controller; or the dimming system further includes a touch screen and a main control, and the touch screen is connected with the dimming controller through the main control.

[0012] It can be seen that the dimming system can further include a touch screen, and the touch screen is connected with the dimming controller, so that the dimming controller can be controlled based on the operation of the touch screen. The touch screen can also be connected with the dimming controller through the main control to control the dimming controller, thereby improving the intelligence of the dimming process.

[0013] For example, the touch screen has a control for whether the dimming function is activated, and when the user touches the control for activating the dimming function, an electrical signal is sent to the dimming controller to activate the dimming function of the dimming controller. In this way, the intelligence of the dimming process is improved, and the user experience is higher.

[0014] In some implementations, the dimming system further includes a first adjustment button and a second adjustment button, and the first adjustment button and the second adjustment button are respectively connected with the input end of the dimming controller.

[0015] In a possible implementation, the first adjustment button and the second adjustment button can be integrated into two operations of one button; or independently deployed as two buttons.

[0016] It can be seen that the dimming system further includes a first adjustment button and a second adjustment button, and the first adjustment button and the second adjustment button are respectively connected with the input end of the dimming controller. Thus, the output result of the dimming controller can be adjusted based on the first adjustment button and the second adjustment button, and the dimming effect is good and the user experience is high.

[0017] For example, if the user is not satisfied with the dimming result of the adjustment controller, the dimming result can be adjusted through the first adjustment button and the second adjustment button, so that the voltage output to the dimming film meets the actual needs of the user.

[0018] In some implementations, in a case where the driver's seat window glass comprises a first area and a second area, the target window glass comprises the second area of the driver's seat window glass; and / or, in a case where the front passenger's seat window glass comprises a first area and a second area, the target window glass comprises the second area of the front passenger's seat window glass; wherein the first area is non-dimming glass, and the second area is dimming glass; the first area is close to the rearview mirror, and the second area is close to the B-pillar.

[0019] It can be seen that the driver's seat window glass and / or the front passenger's seat window glass can comprise non-dimming glass and dimming glass, wherein the first area close to the rearview mirror is non-dimming glass, and the second area close to the B-pillar is non-dimming glass. The dimming glass is determined as the target window glass.

[0020] In other words, the target window glass can be an entire piece of glass, or a certain area of an entire piece of glass, and the dimming system can be applied to various dimming glass scenarios, having the characteristics of wide application.

[0021] In some implementations, in a case where all areas of the rear seat window glass are dimming glass, the target window glass comprises all areas of the rear seat window glass.

[0022] It can be seen that the dimming system can also dim the rear seat window glass to meet the needs of the rear seat passengers.

[0023] In some implementations, in a case where the target window glass is N, and the light sensor is N, N is greater than 1; the dimming controller comprises N input terminals and N output terminals, the N input terminals are connected to the N light sensors one by one, and the N output terminals are connected to the N target window glasses one by one.

[0024] It can be seen that in the dimming system, in a case where the target window glass is multiple, multiple light sensors are deployed, so that the dimming controller realizes the adjustment of a corresponding target window glass based on the detection of one light sensor. In a case where the ambient light distribution is uneven, the dimming needs of the target window glass in different areas can be met through the dimming system.

[0025] In some implementations, the light sensor is disposed on the B-pillar outside the vehicle. In this way, the B-pillar belongs to the support structure of the vehicle, and is more stable when disposed on the B-pillar, and is not affected when the vehicle receives small friction.

[0026] In some implementations, the camera is disposed at any one of the following positions: an A-pillar on the left side of the vehicle, and a central position above the windshield of the vehicle. The camera is disposed at a flexible, stable and reliable position.

[0027] In a second aspect, the utility model provides a kind of vehicle, which can include any dimming system provided in the first aspect.

[0028] The vehicle has the same technical effects as the dimming system, and the description of the dimming system in the first aspect can be referred to. Here, it is not repeated.

[0029] It should be understood that the above description and the following example description are only exemplary and explanatory, but not limiting the technical solutions of the utility model. BRIEF DESCRIPTION OF DRAWINGS

[0039] In order to make the purpose, technical scheme and advantages of the utility model more clear, the technical scheme of the utility model is further described in detail below in combination with the drawings and examples, the described examples should not be regarded as limiting the utility model, all other examples obtained by the person skilled in the art without making creative labor belong to the protection scope of the utility model.

[0040] In the following description, "some embodiments" are referred to, which describe a subset of all possible embodiments, but it can be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments, and can be combined with each other without conflict. The term "first / second / third" referred to is only to distinguish similar objects, and does not represent a specific order of the objects. It can be understood that "first / second / third" can be interchanged with a specific order or sequence as allowed, so that the utility model embodiments described herein can be implemented in an order other than that illustrated or described herein.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the utility model belongs. The terms used herein are only for the purpose of describing the utility model, and are not intended to limit the utility model.

[0042] The utility model embodiment provides a kind of dimming system of vehicle window glass and vehicle. Below, the each embodiment of the dimming system of vehicle window glass and vehicle provided by the utility model embodiment is described.

[0043] In the first aspect, the utility model embodiment provides a kind of dimming system of vehicle window glass. Refer to Figure 1 As shown, the dimming system 10 can include: dimming controller 101, illumination sensor 102 and target vehicle window glass 103, and the target vehicle window glass is dimmable vehicle window glass.

[0044] The target vehicle window glass 103 includes first glass 1031, second glass 1032 and dimming film 1033 between the first glass 1031 and the second glass 1032.

[0045] The input end 1011 of dimming controller 101 is connected with illumination sensor 102, and the output end 1012 of dimming controller 101 is connected with dimming film 1033.

[0046] For illumination sensor 102:

[0047] Illumination sensor 102 is used to collect the ambient brightness outside the vehicle, and convert the ambient brightness into an electrical signal and send it to dimming controller 101.

[0048] The type of the light sensor 102 is not limited in the embodiments of the present application, and can be configured according to actual requirements. For example, the light sensor 102 can include, but is not limited to, a photoresistor sensor, a brightness light photoelectric switch detection sensor, and the like.

[0049] The number of the light sensor 102 is not limited in the embodiments of the present application, and can be configured according to actual requirements. For example, the light sensor 102 can be one or more. The cost of one light sensor 102 is lower, and the accuracy of multiple light sensors 102 is higher.

[0050] The target vehicle window glass 103:

[0051] The target vehicle window glass 103 is a light-adjustable vehicle window glass.

[0052] The light-adjustable glass is a kind of glass whose transparency is controlled by electronic signals. The working principle is that the liquid crystal molecules in the liquid crystal film change in arrangement under the action of an electric field, so as to realize the switching of the glass from transparent to opaque. Specifically, when a voltage is applied, the liquid crystal molecules are arranged in order, and light can penetrate the glass, so that the glass appears transparent; when the power is off, the liquid crystal molecules are arranged in disorder, and light is scattered, so that the glass appears in a fogging state; by changing the voltage over time, the light transmittance of the glass can be adjusted.

[0053] The light-adjustable glass has various types, including polymer dispersed liquid crystal (PDLC), suspension particle device (SPD), and electrochromic (EC), and the like. The type of the target vehicle window glass 103 is not limited in the embodiments of the present application, and can be configured according to actual requirements.

[0054] In one possible implementation, the target vehicle window glass 103 can include a light-adjustable vehicle window glass on a vehicle door.

[0055] In another possible implementation, the target vehicle window glass 103 can further include a rear windshield.

[0056] The target vehicle window glass 103 can be one whole piece of glass, or one light-adjustable region in one whole piece of glass.

[0057] The structure of the target vehicle window glass 103 includes a first glass 1031, a second glass 1032, and a light-adjustable film 1033 located between the first glass 1031 and the second glass 1032.

[0058] The dimming film 1033 is used to adjust the light transmittance of the glass, so as to change the brightness of the glass. Generally, the light transmittance of the dimming film 1033 can be changed by adjusting the voltage value input to the dimming film 1033.

[0059] For the dimming controller 101:

[0060] The dimming controller 101 is used to convert the electrical signal sent by the light sensor 102 into a target voltage for adjusting the light transmittance, and transmit the target voltage to the dimming film 1033 to adjust the light transmittance of the dimming film 1033, and change the light transmittance of the target vehicle window glass 103 through the light transmittance of the dimming film 1033.

[0061] The conversion relationship between the electrical signal and the target voltage can be configured according to actual needs.

[0062] The dimming controller 101 can be multiplexed with a controller for managing the height of the glass and the like, or a separate controller can also be deployed as a dimming controller 101.

[0063] The dimming process of the embodiment can include: collecting the ambient brightness outside the vehicle by the light sensor 102, and converting the ambient brightness into an electrical signal and sending it to the dimming controller 101; the dimming controller 101 converts the electrical signal sent by the light sensor 102 into a target voltage for adjusting the light transmittance, and transmits the target voltage to the dimming film 1033 to adjust the light transmittance of the dimming film 1033, and changes the light transmittance of the target vehicle window glass 103 through the light transmittance of the dimming film 1033.

[0064] It can be seen that the dimming system includes a dimming controller, a light sensor, and a target vehicle window glass. Since the target vehicle window glass is a dimmable vehicle window glass, the input end of the dimming controller is connected with the light sensor, and the output end of the dimming controller is connected with the dimming film. In this way, the dimming controller can adjust the brightness based on the light data detected by the light sensor. In this way, first, when the ambient light brightness is too high, the light sensor can detect a larger ambient brightness, and the dimming controller can adjust the light transmittance of the dimming film to reduce the light transmittance and improve the user's experience of being dazzled. Second, when the ambient brightness is low, the light transmittance can be increased to improve the user's vision. Third, when the ambient brightness is in a normal state, the light transmittance can also be adjusted to a set value to ensure the user's privacy. Thus, the discomfort caused by too bright or too dark ambient light is avoided, and the user experience is improved.

[0065] In another embodiment, with reference to Figure 2As shown in the content, the dimming system 10 further comprises a camera 104, and an output end 1041 of the camera is connected with an input end of the dimming controller 101. Alternatively, the dimming system 10 further comprises the camera 104 and a master controller 105, and the camera 104 is connected with the dimming controller 101 through the master controller 105.

[0066] The output end 1041 of the camera 104 is connected with the input end 1051 of the master controller 105, and an output end 1052 of the master controller 105 is connected with an input end of the dimming controller 101.

[0067] For the camera 104:

[0068] The camera 104 is used for collecting a facial image of a user and transmitting the facial image of the user to the master controller 105. The user can be a driver or a passenger.

[0069] The type and the deployment position of the camera 104 are not limited in the embodiment of the utility model, and can be configured according to actual needs. The camera 104 can be an original camera in a multiplex vehicle, or a camera independently configured for the dimming system.

[0070] For the master controller 105:

[0071] The master controller 105 is used for generating a first signal based on the facial image of the user; and the first signal is used for indicating whether to adjust the light transmittance of the target vehicle window glass.

[0072] Specifically, the master controller 105 is used for identifying a line-of-sight direction in the facial image of the user, and generating the first signal for indicating to adjust the light transmittance of the target vehicle window glass when it is determined that the line-of-sight direction is directed to the target vehicle window glass, and generating the first signal for indicating not to adjust the light transmittance of the target vehicle window glass when it is determined that the line-of-sight direction is not directed to the target vehicle window glass.

[0073] Correspondingly, the dimming controller 101 is further used for: in the case that the first signal indicates to adjust the light transmittance of the target vehicle window glass, sending a collection instruction to the light sensor to make the light sensor collect the environmental brightness outside the vehicle to adjust the light transmittance of the target vehicle window glass; and in the case that the first signal indicates not to adjust the light transmittance of the target vehicle window glass, sending a stop collection instruction to the light sensor to stop collecting the environmental brightness outside the vehicle and stop adjusting the light transmittance of the target vehicle window glass.

[0074] It should be noted that, in the scheme without the master controller 105, the function of the master controller 105 can also be integrated in the camera or the dimming controller.

[0075] The dimming process of this embodiment can include: the camera 104 collects the facial image of the user, and transmits the facial image of the user to the host controller 105; the host controller 105 identifies the line-of-sight direction in the facial image of the user, and generates a first signal for indicating to adjust the light transmittance of the target vehicle window glass when it is determined that the line-of-sight direction points to the target vehicle window glass; the host controller 105 sends the first signal to the dimming controller 101, and the dimming controller 101 sends a collection instruction to the light sensor 102 to make the light sensor 102 collect the ambient brightness outside the vehicle, so as to adjust the light transmittance of the target vehicle window glass. The light sensor 102 collects the ambient brightness outside the vehicle, converts the ambient brightness into an electrical signal, and sends the electrical signal to the dimming controller 101; the dimming controller 101 converts the electrical signal sent by the light sensor 102 into a target voltage for adjusting the light transmittance, and transmits the target voltage to the dimming film 1033, so as to adjust the light transmittance of the dimming film 1033, and change the light transmittance of the target vehicle window glass 103 through the light transmittance of the dimming film 1033.

[0076] When the host controller 105 determines that the line-of-sight direction does not point to the target vehicle window glass, it generates a first signal for indicating not to adjust the light transmittance of the target vehicle window glass; the host controller 105 sends the first signal to the dimming controller 101, and the dimming controller 101 sends a stop collection instruction to the light sensor 102 to make the light sensor 102 stop collecting the ambient brightness outside the vehicle, so as to stop adjusting the light transmittance of the target vehicle window glass 103.

[0077] It can be seen that the dimming system can further include a camera connected with the dimming controller, so that the control of the dimming controller can be realized based on the image detected by the camera. The camera can also be connected with the dimming controller through the main control to realize the control of the dimming controller, thereby improving the intelligence of the dimming process.

[0078] For example, the camera can detect the line-of-sight of the user, so as to determine whether to activate the dimming function based on the line-of-sight of the user. For example, when it is detected that the line-of-sight of the user looks at the target vehicle window glass, an electrical signal is sent to the dimming controller to activate the dimming function of the dimming controller. In this way, the intelligence of the dimming process is improved, and when the line-of-sight does not look at the target vehicle window glass, the dimming function of the dimming controller is cancelled, thereby avoiding the waste of resources and improving the utilization efficiency of resources.

[0079] In another embodiment, referring to the content shown in Figure 3 The dimming system further includes a touch screen 106, and the output end 1061 of the touch screen 106 is connected with the input end of the dimming controller 101; or, the dimming system further includes a touch screen 106 and a host controller 105; the touch screen 106 is connected with the dimming controller 101 through the host controller 105.

[0080] The output end 1061 of the touch screen 106 is connected with the input end 1051 of the master controller 105, and the output end 1052 of the master controller 105 is connected with the input end of the dimming controller 101.

[0081] For the touch screen 106:

[0082] The touch screen 106 is used for receiving a first operation, and the first operation is used for indicating to start or close the dimming function of the target vehicle window glass. The specific type of the first operation is not limited in the embodiment of the utility model. For example, the first operation can be a touch operation on the control for starting the dimming function in the touch screen 106.

[0083] The type, size, shape and deployment position of the touch screen 106 are not limited in the embodiment of the utility model, and can be configured according to actual needs. In a possible implementation manner, the touch screen 106 can be a touch screen in the central control screen or the rear seat, or a touch screen of the co-pilot, and the like.

[0084] Correspondingly, the master controller 105 is used for generating a second signal based on the first operation. The first signal is an instruction corresponding to the first operation. In the case that the first operation is used for indicating to start or close the dimming function of the target vehicle window glass, the second signal is used for indicating to start or close the dimming function of the target vehicle window glass.

[0085] Correspondingly, the dimming controller 101 is further used for: in the case that the second signal represents starting the dimming function of the target vehicle window glass, sending a collection instruction to the light sensor to make the light sensor collect the ambient brightness outside the vehicle. In the case that the second signal represents closing the dimming function of the target vehicle window glass, sending a closing collection instruction to the light sensor to close the collection of the ambient brightness outside the vehicle and close the adjustment of the light transmittance of the target vehicle window glass.

[0086] It should be noted that in the scheme without the master controller, the function of the master controller can also be integrated in the touch screen or the dimming controller.

[0087] The dimming process of the embodiment can include: the user performs the first operation on the touch screen 106, the touch screen 106 receives the first operation, and determines that the first operation indicates to start or close the dimming function of the target vehicle window glass. The first operation is transmitted to the master controller 105, the master controller 105 generates a second signal based on the first operation. The second signal indicates to start or close the dimming function of the target vehicle window glass. The master controller 105 transmits the second signal to the dimming controller 101.

[0088] In a case where the second signal indicates to start the dimming function of the target vehicle window glass, the dimming controller 101 sends a collection instruction to the light sensor 102 to make the light sensor 102 collect the ambient brightness outside the vehicle, so as to adjust the light transmittance of the target vehicle window glass. The light sensor 102 collects the ambient brightness outside the vehicle, converts the ambient brightness into an electric signal, and sends the electric signal to the dimming controller 101. The dimming controller 101 converts the electric signal sent by the light sensor 102 into a target voltage for adjusting the light transmittance, and transmits the target voltage to the dimming film 1033, so as to adjust the light transmittance of the dimming film 1033, and change the light transmittance of the target vehicle window glass 103 through the light transmittance of the dimming film 1033.

[0089] In a case where the second signal indicates to close the dimming function of the target vehicle window glass, the dimming controller 101 sends a closing collection instruction to the light sensor 102 to make the light sensor 102 close the collection of the ambient brightness outside the vehicle, so as to close the adjustment of the light transmittance of the target vehicle window glass 103.

[0090] It can be seen that the dimming system can further include a touch screen connected with the dimming controller, so that the control of the dimming controller can be realized based on the operation of the touch screen. The touch screen can also be connected with the dimming controller through the main control to realize the control of the dimming controller, thereby improving the intelligence of the dimming process.

[0091] For example, the touch screen has a control for the activation of the dimming function. When the user touches the control for activating the dimming function, an electric signal is sent to the dimming controller to activate the dimming function of the dimming controller. In this way, the intelligence of the dimming process is improved, and the user experience is higher.

[0092] In another embodiment, with reference to Figure 4 The dimming system further includes a first adjustment button 107 and a second adjustment button 108, which are respectively connected with the input end of the dimming controller 101.

[0093] The first adjustment button 107 is configured to increase the target voltage in the dimming controller 101.

[0094] The second adjustment button 108 is configured to decrease the target voltage in the dimming controller 101.

[0095] In a possible implementation manner, the first adjustment button and the second adjustment button can be integrated into two operations of one button; or independently deployed as two buttons.

[0096] The type of the first adjustment button 107 and the second adjustment button 108 is not limited in the embodiment of the utility model, and can be configured according to actual requirements. For example, the first adjustment button 107 and the second adjustment button 108 can be integrated into a lifting button, and the target voltage in the dimming controller 101 is increased by lifting operation, and the target voltage in the dimming controller 101 is reduced by lowering operation.

[0097] The first adjustment button 107 and the second adjustment button 108 can be configured as related controls in a touch screen.

[0098] The dimming controller 101 is further used for transmitting the target voltage increased or reduced to the dimming film 1033, so as to adjust the light transmittance of the dimming film 1033, and change the light transmittance of the target vehicle window glass through the light transmittance of the dimming film 1033.

[0099] The dimming process of the embodiment can include: collecting the ambient brightness outside the vehicle through the light sensor 102, and converting the ambient brightness into an electrical signal and sending it to the dimming controller 101; the dimming controller 101 converts the electrical signal sent by the light sensor 102 into a target voltage for adjusting the light transmittance, and transmits the target voltage to the dimming film 1033, so as to adjust the light transmittance of the dimming film 1033, and change the light transmittance of the target vehicle window glass 103 through the light transmittance of the dimming film 1033.

[0100] Suppose the user is not satisfied with the light transmittance of the target vehicle window glass 103 adjusted by the dimming controller 101, and increases the target voltage in the dimming controller 101 or reduces the target voltage in the dimming controller 101 by operating the first adjustment button 107 or the second adjustment button 108, so as to change the target voltage output by the dimming controller 101 to the dimming film 1033, thereby adjusting the light transmittance of the target vehicle window glass based on the operation of the user.

[0101] It can be seen that the dimming system further includes a first adjustment button and a second adjustment button, and the first adjustment button and the second adjustment button are connected with the input end of the dimming controller respectively. Therefore, the output result of the adjustment controller can be adjusted based on the first adjustment button and the second adjustment button, the dimming effect is good, and the user experience is high.

[0102] For example, if the user is not satisfied with the dimming result of the adjustment controller, the dimming result can be adjusted through the first adjustment button and the second adjustment button, so that the voltage output to the dimming film meets the actual requirements of the user.

[0103] In still another embodiment, reference is made to Figure 5As shown in the content, the dimming system can include: a dimming controller 101, a light sensor 102, and a target vehicle window glass 103, a camera 104, a master controller 105, a touch screen 106, a first adjustment button 107, and a second adjustment button 108.

[0104] Wherein, the output of the light sensor 102 is connected with the input of the dimming controller 101, and the output of the dimming controller 101 is connected with the target vehicle window glass 103; the output of the camera 104 is connected with the input of the master controller 105, the output of the master controller 105 is connected with the input of the dimming controller 101, the input of the touch screen 106 is connected with the input of the master controller 105, and the first adjustment button 107 and the second adjustment button 108 are connected with the dimming controller 101 respectively.

[0105] The dimming process of the embodiment can include: starting or closing the dimming function through the camera 104 and the master controller 105, or starting or closing the dimming function through the touch screen 106, i.e. the master controller 105, so as to realize the adjustment of the light transmittance of the target vehicle window glass 103 by the dimming controller 101 through the light sensor 102. Further, in the case that the user is not satisfied with the adjustment, the light transmittance of the target vehicle window glass 103 is adjusted again through the first adjustment button 107 and the second adjustment button 108.

[0106] Next, the target vehicle window glass 103 is described

[0107] In an embodiment, referring to Figure 6 As shown in the content, in the case that the vehicle window glass at the main driver position includes a first area 6011 and a second area 6022, the target vehicle window glass 103 includes the second area 6022 of the vehicle window glass at the main driver position.

[0108] And / or,

[0109] In the case that the vehicle window glass at the co-driver position includes a first area and a second area, the target vehicle window glass includes the second area of the vehicle window glass at the co-driver position.

[0110] Wherein, the first area is a non-dimming glass, and the second area is a dimming glass; the first area is close to the rearview mirror, and the second area is close to the B pillar.

[0111] The size and shape of the first area and the second area are not limited in the embodiment of the utility model, and can be configured according to actual needs.

[0112] The second area close to the B pillar and being a non-dimming glass can ensure that the driving field of view of the driver is not affected.

[0113] It can be seen that the driver's side window and / or the passenger side window can include both non-dimming and dimming glass. Specifically, the first area near the rearview mirror is non-dimming glass, and the second area near the B-pillar is also non-dimming glass. Dimming glass is identified as the target window.

[0114] In other words, the target vehicle window glass can be a whole piece of glass or a certain area of ​​a whole piece of glass. This dimming system can be applied to various dimming glass scenarios and has the characteristics of wide application.

[0115] In another embodiment, when the entire area of ​​the rear seat window is a dimming glass, the target window includes the entire area of ​​the rear seat window.

[0116] It can be seen that the dimming system can also dim the rear window glass to meet the needs of rear passengers.

[0117] Understandably, when the entire rear window is a dimmable pane, the target window includes the entire rear window. This allows for dimmability of the rear window, improving the driver's rearward visibility and enhancing the driving experience.

[0118] In yet another embodiment, reference is made to Figure 7 As shown, when there are N target vehicle window glass 103 and N light sensors 102, N is greater than 1; the dimming controller 101 includes N input terminals 1011 and N output terminals 1012. The N input terminals 1011 are connected to the N light sensors 102 one by one, and the N output terminals 1012 are connected to the N target vehicle window glass 103 one by one.

[0119] The present invention does not specifically limit the number of N, and can be configured according to actual needs.

[0120] The dimming controller 101 has one input terminal 1011 and one output terminal 1012.

[0121] The dimming controller 101 is also used to: convert an electrical signal from an input terminal 1011 into a target voltage and send it to a target vehicle window 103 through an output terminal 1012 bound to the input terminal 1011, so as to adjust the light transmittance of a target vehicle window 103 based on an electrical signal from a light sensor 102.

[0122] The dimming process in this embodiment may include:

[0123] It can be seen that in the dimming system, multiple light sensors are arranged for multiple target vehicle window glasses, so that the lightness of a corresponding target vehicle window glass is adjusted based on the detection of one light sensor through the dimming controller. In the case of uneven ambient light distribution, the dimming needs of target vehicle window glasses in different areas can be met through the dimming system.

[0124] Next, the deployment position of the light sensor is described.

[0125] In another embodiment, the light sensor 102 is arranged on the B pillar outside the vehicle. In this way, the B pillar belongs to the support structure of the vehicle, and the arrangement on the B pillar is more stable and is not affected when the vehicle receives small friction.

[0126] In another embodiment, the light sensor 102 can be arranged on the front or rear of the vehicle, on the door, etc.

[0127] In a possible implementation, if the number of target vehicle window glasses and light sensors is N, the target vehicle window glasses include the vehicle window glass of the main driver position, the vehicle window glass of the co-driver position, the vehicle window glass of the rear seat, and the rear windshield. Two light sensors can be arranged on two B pillars, two light sensors can be arranged at appropriate positions of two rear doors, and one light sensor can be arranged at an appropriate position of the trunk. Thus, the ambient brightness of each position area can be accurately collected.

[0128] In another embodiment, the camera is arranged at any of the following positions: the A pillar on the left side in the vehicle, and the central position above the windshield in the vehicle. The deployment position is flexible, stable, and reliable. The camera can also be arranged at other positions, which are not listed one by one here.

[0129] In a possible implementation, if the target vehicle window glasses include the vehicle window glass of the main driver position, the vehicle window glass of the co-driver position, and the vehicle window glass of the rear seat, the corresponding camera needs to collect the images of the driver, the co-driver, and the rear seat passenger, so the camera can be arranged at the central position above the windshield. Alternatively, multiple cameras can be arranged to achieve accurate image collection.

[0130] Next, the dimming system of the vehicle window glass of the utility model is implemented through an embodiment.

[0131] The current front glass of the vehicle is difficult to protect privacy, and generally has a dark film. When the vehicle window is pasted with a dark film, the night vision is not clear.

[0132] In this embodiment, when the driver monitoring system (DMS) detects that the user is observing the objects outside the left and right windows, the window on the observed side is controlled to change color to transparent, maintaining good vision, and automatically changing the window to deep black in the case of not observing to protect privacy.

[0133] The implementation process can include, but is not limited to, the following steps 1 to 6.

[0134] Step 1, the A-pillar-mounted DMS camera in the cockpit monitors the driver's line of sight.

[0135] Step 2, referring to the content shown in the figure, the light sensor 102 mounted on the B-pillar 801 of the vehicle body judges the ambient brightness through the light sensor. Figure 8

[0136] Step 3, referring to the content shown in the figure, the window is composed of two parts a and b, part a is ordinary glass, used to provide the driver with a view of the rearview mirror, part b is an electrically adjustable light transmittance glass (smart dimming glass, also known as dimming glass). Figure 8

[0137] Step 4, the car machine combines the collected ambient light and the driver's line of sight information to determine the glass that needs to be adjusted and the light transmittance that needs to be adjusted.

[0138] Step 5, the car machine sends a transparency adjustment signal.

[0139] Step 6, the controller of the window glass adjusts the transparency according to the received signal.

[0140] The structure of this dimming system can refer to the content shown in the figure, which includes: DMS camera 901, power supply 1 902, display screen 903, double data rate synchronous dynamic random access memory (DDR) 904, main processor 905 (equivalent to the above-mentioned main controller), window microcontroller unit (MCU) 906 (equivalent to the above-mentioned dimming controller), power supply 2 907, electrically adjustable window glass 908, light brightness sensor 909 (equivalent to the above-mentioned light sensor), and power supply 3 910. Figure 9

[0141] ​​​Among them, the main processor 905 and the window MCU 906 transmit signals based on the local network (Local Interconnect Network, LIN) bus. The window MCU 906 and the electrically adjusted window glass 908 transmit voltage signals. The light line brightness sensor 909 and the window MCU 906 transmit inter-integrated circuit (I2C) signals.
