BACKGROUND

With the development of smart glass technology, more and more smart glass has been applied to various aspects of people's lives. The smart glass includes light-adjusting glass, interactive glass, light-emitting glass, etc. The light-emitting glass may be configured in different colors and patterns as required, thereby creating different display effects. Typically, a light-emitting effect of a light-emitting pattern is achieved by a light extraction structure formed on the surface or inside of the glass to export light entering the inside of the glass to the surface of the glass, or by a light-emitting element disposed on the surface or the inside of the glass to actively emit light.

Currently, however, the light-emitting glass is typically controlled as a fixed variety of modes through a unified interface and thus the control method is simple and lacks interaction with users.

In the present disclosure, “a plurality of” means two or more, unless otherwise specifically defined. In addition, in the present disclosure, unless otherwise specifically defined, terms such as “installation” , “connection” , and “attachment” should be understood in a broad sense.

In the present disclosure, the glass assembly is described as being applied to a vehicle window glass, but it is not excluded that the glass assembly may be applied to an environment such as a door, a window, a curtain wall, aircraft glass, or ship glass. When the glass assembly is described as a window glass for a vehicle, “outer” and “inner” refer to directions relative to the vehicle body. “Outer” refers to a direction away from the vehicle body, while “inner” refers to a direction toward the space formed by the vehicle body. It should be understood that the window glass according to the embodiments of the present disclosure includes, but is not limited to, a front windshield, a rear windshield, a sunroof glass, a door glass, or a corner glass.

The light-emitting glass has a light-emitting function, and is configured to implement functions such as lighting, display, and decoration. FIG. 1 shows a schematic diagram of a light-emitting glass according to an embodiment of the present disclosure. Alight-emitting pattern 101 on a light-emitting glass 100 in FIG. 1 may be observed from an inside or outside view of the vehicle. In some examples, the light-emitting glass itself does not have light-emitting characteristics, but can export light from an external light-emitting element. For example, a pattern layer of a light extraction material or a light extraction structure may be formed on the surface or inside of the glass, or a pattern of the light extraction structure may be formed by micro-engraving inside the glass. When the external light-emitting element injects light into the inside of the glass, the pattern of the light extraction material or the light extraction structure exports the light to the outside of the glass due to a scattering or diffusion effect, and a light-emitting effect is presented to form a light-emitting pattern. In some other examples, the light-emitting glass may emit light by means of self-luminous technology without the need for an external light source, for example, by embedding an active light-emitting element inside the glass or by setting them on the surface of the glass to directly emit light to form the light-emitting pattern.

As described above, the current control of the light-emitting glass is relatively simple and lacks interaction with the user. Although it is possible to control the state of the light-emitting glass by pressing a button, remote control, or software application touch, these methods usually require manual adjustment of the driver, with the risk of compromising driving safety. Moreover, most of these methods focus only on the driver's sensory experience, with little consideration for the passenger's experience, especially in the rear.

The technical solution according to the present disclosure will be described in detail below according to several embodiments. A control method for a light-emitting glass assembly according to a first aspect of the present disclosure is firstly introduced. Specifically, FIG. 2 shows a flowchart of a control method 200 for a light-emitting glass assembly according to an embodiment of the present disclosure.

The control method 200 for the light-emitting glass assembly according to the embodiment of the present disclosure may apply to the cases where the light-emitting glass emits light passively and actively. In some examples, the light-emitting glass emits light passively. The light-emitting glass assembly may include a glass substrate, a light-emitting element, and a light extraction structure disposed inside or on at least one surface of the glass substrate. The light-emitting element is configured to emit light into the glass substrate. The light extraction structure is configured to export light emitted by the light-emitting element incident into the glass substrate to at least one surface of the glass substrate to present a light-emitting pattern. In some other examples, the light-emitting glass emits light actively. The light-emitting glass assembly may include a glass substrate and a light-emitting element disposed inside or on at least one surface of the glass substrate. The light-emitting element is configured to actively emit light and to cause light to exit from at least one surface of the glass substrate to present a light-emitting pattern.

As shown in FIG. 2, the control method 200 for the light-emitting glass assembly may be specifically described as follows.

In S201, human body detection information near a light-emitting glass assembly is received.

In some examples, where the light-emitting glass emits light passively, "near the light-emitting glass assembly" may refer to in a vicinity of a side of the glass or in the vicinity of a region where the pattern of the light extraction structure inside is located. The region where the pattern is located may be an area in which a scattering enamel or ink is applied to the side of the glass to form a designed flat patterned, or the area in which a film layer having the pattern is pressed onto the surface of the glass. Alternatively, the region where the pattern is located may be a three-dimensional pattern design region formed by laser engraving inside or on one side of the glass. In some other examples, where the light-emitting glass emits light actively, "near the light-emitting glass assembly" may refer to in the vicinity of the light-emitting element that actively emits light. The vicinity here refers to a certain threshold distance from the light-emitting glass assembly.

The human body detection information near the light-emitting glass assembly may indicate whether there is a human body and/or a change in the human body. The change in the human body may be, for example, a change in distance or movement. In some examples, detecting the presence of the human body may be implemented by detecting a biological signal of the human body, such as at least one of voice, gesture, temperature, and face. In other words, non-contact human body detection information is used as a signal input without using a key, a knob, a touch, etc.

In some examples, the human body detection information may be collected by various recognition apparatuses or sensors at or near the light-emitting glass assembly. For example, the presence of a human body may be detected by at least one recognition apparatus, such as a voice recognition apparatus and a camera that captures videos/images in a visible wavelength range to collect a specific voice, a specific gesture, or a specific person's face. For another example, the signal indicating that the presence of the human body may be collected by using a proximity sensor, for example, at least one of a capacitive proximity sensor, an infrared sensor, a radar sensor, a laser sensor, an ultrasonic sensor, or a radio frequency sensor.

In S202, in response to the human body detection information, a light-emitting state of a light-emitting element is adjusted, thereby changing a light-emitting pattern presented on at least one surface of a glass substrate.

The light-emitting element may be located on the top surface of the glass substrate, on the bottom of the glass substrate, or integrated inside the glass substrate. In the case where the light-emitting glass emits light passively, when the incident light from the light-emitting element is projected to the light extraction structure, due to changes in the surface structure, the light is scattered and transmitted through the light-emitting pattern, which in turn achieves a patterned light-emitting illumination effect. In some examples, the light-emitting element may be a halogen lamp, an electroluminescent diode LED lamp, or a laser lamp. The light-emitting element may be a dotted or linear light source, such as an LED light bar or an LED lamp bead. In the case where the light-emitting glass emits light actively, the light-emitting element may be an active light-emitting element, such as a transparent OLED module. The transparent OLED module may be embedded inside or on the surface of the glass substrate.

The light-emitting state of the light-emitting element may be adjusted or maintained according to the received human body detection information. For example, when the human body detection information indicates the presence of the human body, the light-emitting element may be turned on so that the pattern is illuminated for display. Alternatively, when a human body detection signal does not change within a predetermined time threshold, the light-emitting state of the current light-emitting element is maintained, and the light-emitting pattern remains illuminated for display. Alternatively, when no human body is detected within a certain time range, the light-emitting element may be turned off and the pattern is not illuminated for display. Alternatively, the state of the light-emitting element, such as duration, brightness, and color, may be correspondingly adjusted according to changes in the human body detection information, to correspondingly adjust the display state of the light-emitting pattern.

The control method 200 for the light-emitting glass assembly determines the light-emitting state of the light-emitting element according to the human body detection information near the light-emitting glass assembly without manual adjustment by the driver through a control interface, thereby improving the driving safety. In addition, the automatic adjustment of the light-emitting state based only on human body detection information near the light-emitting glass assembly allows for increased interaction with passengers, especially those in the rear.

In some embodiments, the light-emitting pattern of the light-emitting glass assembly may be uniformly controlled. For example, when the human body detection information indicates the presence of the human body, all parts of the light-emitting element is turned on, and the entire light-emitting pattern is illuminated at the same time.

In some examples, the human body detection information may be received at a particular position near the light-emitting pattern. For example, a sensor may be provided in the middle of the bottom of the light-emitting glass substrate. When the sensor detects the presence of a person nearby, the sensor emits a human body detection signal. For another example, sensors may be provided in the middle of edges of the light-emitting glass substrate. When a certain sensor detects the presence of a person nearby, the certain sensor emits a human body detection signal. In some other examples, corresponding sensors may be respectively disposed at positions corresponding to different light-emitting patterns. That is, each or a certain edge of the light-emitting glass substrate is provided with multiple sensors. In this way, when a human body detection signal is received near different light-emitting patterns, a corresponding sensor sends out a human body detection signal.

In some examples, the light-emitting state of the light-emitting element may be adjusted based on human body detection information received at a particular position near the light-emitting pattern. For example, when the human body detection information is received in the middle of the bottom of the light-emitting glass, all parts of the light-emitting element are turned on to illuminate all the light-emitting patterns. For another example, when the human body detection information is received in the middle of a certain edge of the light-emitting glass, all parts of the light-emitting element are turned on to illuminate all the light-emitting patterns.

In some other embodiments, a partial light-emitting pattern of the light-emitting glass assembly may be individually controlled. Specifically, S202 may include the following steps, referring to FIG. 3. FIG. 3 shows a flowchart of a control method 210 for a light-emitting glass assembly according to another embodiment of the present disclosure. As shown in FIG. 3, a control method 210 for the light-emitting glass may be specifically described as follows.

In S211, a first pattern region on the glass substrate is determined correspondingly according to a first relative position information between the human body and the glass substrate at a first moment.

In some examples, the human body detection information may include relative position information between the human body and the glass substrate. The relative position information may refer to the position information of the human body or a part of the human body relative to a certain position of the glass substrate as an origin. Alternatively, the relative position information may refer to the position information of the human body or a part of the human body relative to the certain position of the glass substrate, using a certain position of the vehicle as the origin. In this way, a partial region of the light-emitting pattern may be determined according to the relative position information.

A first pattern region on the glass substrate is determined correspondingly according to a first relative position information between the human body and the glass substrate at a first moment T1. For example, at T1, when the relative position between the human body and a certain light extraction structure of multiple light extraction structures of the glass substrate meets a predetermined distance requirement, the pattern region corresponding to the certain light extraction structure on the glass substrate may be determined as the first pattern region. For another example, at T1, when the relative position between the human body and a certain sub-element of the active light-emitting element of the glass substrate meets the predetermined distance requirement, the pattern region corresponding to the certain sub-element on the glass substrate may be determined as the first pattern region.

In S212, a first light-emitting element group of the light-emitting element corresponding to the first pattern region is determined.

Different pattern regions may correspond to different parts of light-emitting element, which may enable individual control of the different pattern regions. The first light-emitting element group corresponding to the first pattern region may be determined according to the correspondence between pattern regions and light-emitting elements.

In S213, a light-emitting state of the first light-emitting element group is adjusted, thereby changing a first light-emitting pattern presented in the first pattern region of the glass substrate.

The light-emitting state of a certain light-emitting element group, such as one or more of on/off, light-emitting brightness, light-emitting color, and light-emitting duration, may be adjusted according to the determined light-emitting element group. Since the light-emitting state of the light-emitting element is adjusted, the state of the light-emitting pattern presented in the pattern region corresponding thereto may be adjusted.

In some embodiments, the light-emitting element or the light-emitting pattern on the light-emitting glass may be controlled in groups. For example, FIG. 4 shows a flowchart of a method 300 for determining a first light-emitting element group according to an embodiment of the present disclosure. As shown in FIG. 4, the method 300 for determining the first light-emitting element group may be specifically described as follows.

In S301, a glass substrate is divided into multiple pattern regions.

Grouping the light-emitting patterns on the glass substrate can realize personalized control of different light-emitting patterns. The pattern regions on the glass substrate may be divided into at least two groups, and each group may be independently controlled.

The pattern region on the glass substrate may refer to a region where the light extraction structure or the active light-emitting element presents a light-emitting pattern on at least one surface of the glass substrate. In some examples, the pattern region may be evenly divided, such as by dividing the entire pattern region into multiple groupings according to equal parts of the area or by grouping the pattern region according to their constituent units. In some examples, grouping may be performed according to the complexity of the pattern region. For example, the grouping for more complex pattern region is finer. Specifically, the complexity of the pattern region may mean that there are more patterns per unit area or more lines/types of patterns per unit area.

In S302, a correspondence between the multiple pattern regions and the light-emitting element is determined.

The light-emitting element may include multiple light-emitting sub-units. The correspondence between the multiple pattern regions and the light-emitting element may be set according to actual needs. For example, one or more light-emitting sub-units of the light-emitting element may control a group of pattern regions. That is, each group of pattern regions may correspond to one or more light-emitting sub-units. Each group of pattern regions as grouped may be in one-to-one correspondence with one or more light-emitting sub-units of the light-emitting element, that is, the one or more light-emitting sub-units control the light-emitting effect corresponding to the group of pattern regions.

In some examples, the light-emitting element may also be uniformly laid out for cases where the pattern regions are evenly divided. For example, each group of light-emitting element includes an equal number of light-emitting sub-units. The uniform layout of the light-emitting element can improve the illuminance uniformity. In some examples, for cases where the pattern regions are grouped according to complexity, the number of light-emitting sub-units in each group of light-emitting element corresponding to a more complex pattern region may be set to be larger, so as to improve the layer and aesthetics of the light-emitting pattern.

In S303, the first light-emitting element group corresponding to the first pattern region is determined based on the correspondence.

A corresponding light-emitting element is determined according to the grouped pattern regions and the corresponding relationship between the pattern regions and the light-emitting element. The first light-emitting element group corresponding to the determined first pattern region may be determined based on the correspondence.

In some embodiments, when a human body detection signal is detected at a certain group of pattern regions, the corresponding group of the light-emitting element is turned on to light up the group of pattern regions. In this way, the corresponding grouping control of pattern regions and light-emitting element can present a variety of display effects. For example, when the human approaches each group of pattern regions one by one, each light-emitting element group is illuminated in turn to present the effect of dynamically displaying each group of patterned regions. More specifically, when the hand of a passenger sitting in the rear seat approaches a certain part of the pattern on the rear window, the corresponding light-emitting element group is turned on due to the human body detection signal sensed near the part so that the pattern of the part is illuminated. As the hand moves, other groups of pattern regions are sequentially illuminated. In this scenario, the pattern display of the light-emitting glass on the window is controlled by the passenger without the driver's manipulation. In addition, for younger passengers, the process can be more interactive and thus soothing during a long trip or waiting in the vehicle.

The above method for controlling the light-emitting state of the light-emitting element is only an example, and the means of adjusting the light-emitting state of the light-emitting element in the present disclosure is not limited thereto, and may be flexibly set according to specific scenarios or requirements. Several examples are given below.

Example1

In some embodiments, the light-emitting state of the light-emitting element includes an on state or an off state, and adjusting the light-emitting state of the light-emitting element includes switching the on state and the off state of the light-emitting element. In some examples, when the current state of the light-emitting element is off, adjusting the light-emitting state of the light-emitting element may be turning on all parts of the light-emitting element; when the current state of the light-emitting element is on, adjusting the light-emitting state of the light-emitting element may be turning off all parts of the light-emitting element.

In some examples, when the pattern regions and the light-emitting element are controlled in groups, the current state of each light-emitting element group is off, and adjusting the light-emitting state of the light-emitting elements may be turning on a certain light-emitting element group. For example, in a scenario where the light-emitting glass is applied to a vehicle door glass, the initial state of the light-emitting element is off. A human body detection signal at or near each group of pattern regions is collected by a human body detection signal collection apparatus. When the hand of the passenger moves near the group A pattern region, the corresponding light-emitting element group is turned on, and the group A pattern region is illuminated. As the passenger's hand moves randomly, the pattern regions located on the light-emitting glass corresponding to the other groups B, C, D, etc... are ill uminated in turn.

In addition to switching between the on state and the off state, in some embodiments, when the current state of the light-emitting element is the on state, adjusting the light-emitting state of the light-emitting element may also be adjusting the on state of the light-emitting element, where the on state includes one or more of light-emitting brightness, light-emitting color, and light-emitting duration.

Example2

In some embodiments, the human body detection information further includes a relative distance between the human body and the glass substrate. The control method 210 for the light-emitting glass assembly may further include: adjusting the light-emitting state of the first light-emitting element group according to the relative distance between the human body and the glass substrate, thereby changing the first light-emitting pattern presented in the first pattern region of the glass substrate.

In some examples, the initial state of the light-emitting element of the light-emitting glass assembly is off, and a human body detection signal at or near the pattern region is collected by a human body detection signal collection apparatus. When the received human body detection information indicates the presence of a human body near the pattern region, the pattern region is illuminated by the corresponding light-emitting element. After the pattern region is illuminated, the distance between the pattern region on the glass substrate and the human body is continuously detected. For example, the distance may be calculated by using at least one of a laser distance sensor, an ultrasonic distance sensor, an infrared ranging sensor, and a time-of-flight sensor. When the distance changes, the on state of the light-emitting element may be adjusted. For example, when the distance decreases, the light-emitting brightness of the light-emitting element may be increased, such as from light white to bright white. Otherwise, when the distance increases, the light-emitting brightness of the light-emitting element may be decreased. For another example, the light-emitting mode of the light-emitting element may be changed when the distance varies, e.g., as the distance decreases, the light-emitting element changes from a constant light mode to a flickering mode, or the displayed color of the light-emitting element is changed.

In the case where the light-emitting glass assembly is applied to a vehicle door/sunroof glass, and the initial state of a light-emitting element of the light-emitting glass assembly is off, the human body detection signal at or near the pattern region is collected by the human body detection signal collection apparatus. When the human body detection signal received near the group A pattern region indicates the presence of a human body nearby, e.g., when the hand of the passenger approaches the group A pattern region of the door/sunroof glass, the group A pattern region is illuminated. After the group A pattern region is illuminated, the distance between the group A pattern region and the human body is continuously detected. When the distance decreases, the light-emitting brightness of the light-emitting element increases, so that the group A pattern region gradually becomes brighter. Otherwise, when the distance increases, the light-emitting brightness of the light-emitting element decreases, so that the group A pattern region gradually becomes darker. For another example, when the distance decreases, the group A pattern region changes from being constantly bright to being displayed in a flickering manner, or the color system of the group A pattern region changes.

In the case where the initial state of the light-emitting glass is off, when the hand of the passenger sequentially passes through each group of pattern regions, for example, group A pattern region, group B pattern region, etc. . ., these pattern regions may be sequentially illuminated for a certain time range. During this period, the distance between each group of pattern regions and the hand of the passenger may be detected. The light-emitting state of the corresponding light-emitting element may be adjusted according to the change of the distance. In this way, the display of the pattern region of the light-emitting glass is completely controlled by the hand of the passenger, and the pattern region can be dynamically displayed due to the consideration of the change of the distance, thereby increasing the interaction with the passenger.

Example3

In some embodiments, the control method for the light-emitting glass assembly further includes adjusting different parts of light-emitting element according to different relative position information at different moments. The control method 210 for the light-emitting glass assembly may further include the following steps: determining a second pattern region on the glass substrate correspondingly according to a second relative position information between the human body and the glass substrate at a second moment T2; determining a second light-emitting element group of the light-emitting element corresponding to the second pattern region; and adjusting a light-emitting state of the second light-emitting element group, so as to change a second light-emitting pattern presented in the second pattern region of the glass substrate. These steps are similar to S211-S213 and therefore are not repeated.

In some embodiments, the method 210 further includes obtaining a time interval of the human body detection signal in different pattern regions, and determining light-emitting states of different parts of light-emitting element according to the time interval. For example, the method 210 further includes the following steps.

In S2111, a time interval between the second moment T2 and the first moment T1 is determined.

In S2112, the light-emitting states of the first light-emitting element group and/or the light-emitting states of the second light-emitting element group are adjusted according to the time interval, so as to change the first light-emitting pattern presented in the first pattern region and/or the second light-emitting pattern presented in the second pattern region of the glass substrate.

In some examples, the initial state of the light-emitting element of the light-emitting glass assembly is off, and a human body detection signal indicates the human body detection signal at or near different pattern regions. When the received human body detection signal indicates the presence of a human body near a certain pattern region, the certain pattern region is illuminated. After the pattern region is illuminated, the human body detection signal at or near other pattern regions is continuously detected. When the human body detection signals are detected at neighboring pattern regions and are illuminated sequentially, a time interval of the human body detection signals at different pattern regions is obtained. In some examples, the time interval may be obtained by a timer. The light-emitting states of different parts of light-emitting element may be adjusted according to the acquired time interval. For example, when the time interval is greater than a first interval threshold, the turn-on time of the light-emitting element may be increased, such as from 1s to 2s or 5s. Otherwise, when the time interval is less than or equal to a second interval threshold, the turn-on time of the light-emitting element may be decreased, such setting the turn-on time as 0.5s. For another example, when the time interval is greater than the first interval threshold, the light-emitting mode of the light-emitting element may be set to a monochromatic mode. When the time interval is less than or equal to the second interval threshold, the light-emitting mode of the light-emitting element may be set to a chromatic mode. The first interval threshold herein is greater than the second interval threshold.

In the case where the light-emitting glass assembly is applied to a vehicle door/sunroof glass, the initial state of a light-emitting element of the light-emitting glass assembly is off. The human body detection signal at or near different pattern regions is collected by the human body detection signal collection apparatus. When the human body detection signal received near the group A pattern region indicates the presence of a human body nearby, e.g., when the hand of the passenger approaches the group A pattern region of the door/sunroof glass, the group A pattern region is illuminated. After the group A of pattern region is illuminated, the human body detection signal of other groups of pattern regions is continuously detected. When the human body detection signal is detected at neighboring groups B, C, and D pattern regions and these pattern regions are illuminated sequentially, the time interval of the human body detection signal at different pattern regions is obtained. When the time interval is greater than the first interval threshold (for example, 1s) , the turn-on time of the light-emitting elements in the corresponding group may be set to 2s. Otherwise, when the time interval is less than or equal to the second interval threshold (for example, 100ms) , the turn-on time of the light-emitting element in the corresponding group may be set to 0.5s. For another example, when the time interval is greater than the first interval threshold, the light-emitting mode of the light-emitting element may be set to the monochromatic mode, e.g., as an orange or blue color. When the time interval is less than or equal to the second interval threshold, the light-emitting mode of the light-emitting element may be set to the chromatic mode.

In the case where the initial state of the light-emitting glass is off, when the hand of the passenger sequentially passes through each group of pattern regions, for example, group A pattern region, group B pattern region, etc. . ., these pattern regions may be sequentially illuminated for a certain time range. During this period, time intervals of different groups of pattern regions as illuminated may be detected, so that the light-emitting state of the corresponding part light-emitting element may be adjusted according to changes in the time intervals. Such processing considers the fact that when the rear passenger is a child, the hand control action is relatively repeated or simple. Therefore, setting the light-emitting state of the light-emitting element according to the time intervals can increase the display complexity and the interaction, which is advantageous in scenarios with long waiting times.

Example4

In some embodiments, the human body detection information further includes gesture information or motion information of the human body, and adjusting the light-emitting state of the light-emitting element in response to the human body detection information in the control method for the light-emitting glass assembly further includes: adjusting the light-emitting state of the first light-emitting element group according to the gesture information or the motion information, so as to change the first light-emitting pattern presented in the first pattern region of the glass substrate.

In some examples, the initial state of the light-emitting element of the light-emitting glass assembly is off, and a human body detection signal at or near the pattern region is collected by a human body detection signal collection apparatus. When the human body detection information indicates the presence of a human body near the pattern region, the part or all of the pattern region is illuminated by the corresponding light-emitting element. After the pattern region is illuminated, a gesture or motion near the pattern region is detected. For example, a gesture recognition sensor may be used to collect the gesture motion. When the collected gesture motion meets a requirement, the light-emitting state of the light-emitting element will be correspondingly adjusted. In some other examples, motion information of a facial or human posture may also be collected. When the motion information meets a predetermined condition, the light-emitting state of the light-emitting element will be correspondingly adjusted.

For example, in the case where the light-emitting glass is applied to the sunroof glass, and the initial state of the light-emitting element of the light-emitting glass assembly is off, the human body detection signal collection apparatus, such as an infrared sensor, acquires a human infrared signal at or near the pattern region. When a person is detected at or near a first pattern region of the pattern region, the first pattern region is illuminated. The gesture recognition sensor captures and collects the gesture motion. If the collected gesture motion meets a recognition requirement, the light-emitting element may be adjusted to be in a corresponding light-emitting state, such as light-emitting brightness adjustment, color switching, and breathing frequency control. For another example, when a person is detected at or near the first pattern region of the pattern region, the gesture recognition sensor starts to work to capture a gesture motion. If the collected gesture motion meets the recognition requirement, the first light-emitting element may be adjusted to be in a corresponding light-emitting state, such as on/off, brightness adjustment, color switching, breathing frequency control.

In addition to being implemented by means of a control method such as software, the foregoing technical solution can also be implemented, for example, by a corresponding hardware circuit. In other words, the above control method for the light-emitting glass can be implemented by software stored in a computer-readable storage medium in combination with corresponding hardware components. The computer-readable storage medium carries computer-readable program instructions for executing various embodiments of the present disclosure. The computer-readable storage medium may be a tangible device that can retain and store instructions for use by an instruction execution device. The computer-readable storage medium may be, for example, but is not limited to, an electronic storage device, amagnetic storage device, an optical storage device, an electromagnetic storage device, asemiconductor storage device, or any suitable combination of the foregoing. More specific examples (non-exhaustive) of the computer-readable storage medium would include the following: a portable computer diskette, a hard disk, a random access memory (RAM) , aread-only memory (ROM) , an erasable programmable read-only memory (EPROM or Flash memory) , a static random access memory (SRAM) , a portable compact disc read-only memory (CD-ROM) , a digital versatile disk (DVD) , a memory stick, a floppy disk, amechanically encoded device such as punch-cards or raised structures in a groove having instructions recorded thereon, and any suitable combination of the foregoing. The computer-readable storage medium, as used herein, is not to be construed as being transitory signals per se, such as radio waves or other freely propagating electromagnetic waves, electromagnetic waves propagating through a waveguide or other transmission media (e.g., light pulses passing through a fiber-optic cable) , or electrical signals transmitted through a wire.

In addition, the present disclosure also relates to a control unit of a light-emitting glass assembly. FIG. 5 shows a schematic diagram of a control unit 400 according to an embodiment of the present disclosure. As shown in FIG. 5, the schematic diagram of the control unit 400 includes a processor 410 and a memory 420 coupled with the processor 410. The processor 410 is, for example, a central processing unit (CPU) . The memory 420 stores computer-readable instructions, and when the computer-readable instructions are executed by the processor 410, the processor 410 is caused to implement the control method for the light-emitting glass assembly according to the first aspect of the present disclosure. The processor 410 and the memory 420 are connected to each other through a bus, and an input/output (I/O) interface is also connected to the bus. In addition, the control unit 400 may further include an output unit, and the output unit may include an autonomous display functional layer and/or a light source. In some examples, the autonomous display functional layer may be, for example, a flexible OLED display, which may be sandwiched in or attached to the front cover glass, the side window glass, and the back cover glass.

In addition, the control unit 400 may further include multiple components (not shown in FIG. 5) connected to the I/O interface, including but not limited to: an in-vehicle interaction interface of a touchscreen, a sensor, an in-vehicle clock, a timer communicatively connected to the vehicle, an electronic device in communication with the vehicle, a keyboard, a mouse, and the like; an output unit, for example, the output unit may include an autonomous display function layer and/or a light source, and various types of displays, speakers, and the like; a storage unit, for example, a magnetic disk, and an optical disk; and a communication unit, for example, a network card, a modem, and a wireless communication transceiver. The communication unit allows the control unit 400 to exchange information/data with other devices through a computer network such as the Internet and/or various telecommunication networks.

At this time, the computer-executable instructions stored in the memory 420, when executed, cause the processor 410 to perform the control method for the light-emitting glass assembly according to any one of the embodiments shown in FIGS. 2 to 4 of the present disclosure.

In some embodiments, the control unit may be a module combining independent hardware and software or any suitable hardware module. In some examples, the control unit may be integrated with the vehicle control unit when applied to vehicle glass. The vehicle control unit may be any control unit, including a vehicle end, for example, an in-vehicle electronic control unit (ECU) including a central control unit, an in-vehicle entertainment system, a vehicle body control unit, and the like.

In some embodiments, the control unit is configured to communicate with a sensor unit and/or a switching apparatus, etc., to enable the control unit to provide illumination in response to signals or instructions of the sensor unit and/or the switching apparatus. The communication protocols include, but are not limited to, LIN, CAN, Melibus, ISELED, or other types of transmission buses.

FIG. 6 shows a schematic diagram of a light-emitting glass assembly 600 according to an embodiment of the present disclosure. The light-emitting glass assembly 600 includes a glass substrate 601, a light extraction structure 602, a light-emitting element 603, and a control unit (not shown) . The glass substrate 601 includes at least one surface. The light-emitting element 603 is configured to emit light into the glass substrate. The light extraction structure 602 is disposed inside or on at least one surface of the glass substrate. The light extraction structure is configured to export light incident into the glass substrate to the at least one surface of the glass substrate to present a light-emitting pattern. The light-emitting glass assembly 600 may further include at least one sensor unit 604 configured to provide the human body detection information. The at least one sensor unit 604 may be one or more of a proximity sensor, a distance sensor, and a gesture motion sensor.

FIG. 6 shows that when the hand of the passenger moves to the vicinity of the first group of pattern regions, the corresponding light-emitting element group is turned on, and the group of pattern regions is illuminated. The light-emitting element 603 is mounted on the bottom of the glass substrate. The sensor unit 604 is mounted in the non-window area of the vehicle door. From the perspective of the passenger, the light-emitting element 603 and the sensor unit 604 are not visible.

In some embodiments, the glass substrate 601 is a single-layer structure, and the light extraction structure 602 is disposed on a surface of the glass substrate. In some examples, the light extraction structure may be a planar pattern formed by printing a film layer, enamel, ink, or other scattering particles onto the surface of the glass substrate. In some other examples, the light extraction structure may be a three-dimensional pattern formed by laser engraving on the surface of the glass substrate.

In some embodiments, the glass substrate 601 is a double-layer glass plate. The light extraction structure is disposed on an outer surface of the glass plate or sandwiched in the middle of the double-layer glass plate.

In some embodiments, the light-emitting element 603 is disposed at an edge of the glass substrate. For example, the light-emitting element may be an LED light bar or an LED lamp bead. The light-emitting element 603 may be configured to emit light into the glass substrate. Compared with the case where the light-emitting element is disposed on the surface of the glass substrate, the LED lamp may be disposed at the bottom of the edge of the glass substrate, such as in the thickness direction, so that the light-emitting glass assembly is more suitable for the vehicle door glass in the lifting friction environment, thereby improving the service life thereof. In addition, placing the light-emitting element on the surface of the glass substrate rather than in the glass body can reduce the process cost and is more suitable for a wide range of applications.

In some embodiments, the light-emitting element 603 may include a light source and a light guide element. The incident light emitted by the light source is guided through the light guide element, enters the glass substrate, and is totally reflected in the glass substrate. The light guide element is beneficial to reduce the light loss and improve the luminous visual effect. The light source, the light guide element, and the glass substrate may be mounted to each other by bonding or mechanical connection.

In some examples, the light-emitting element 603 is one or more of a monochromatic lamp bead, a three-color RGB lamp bead, or a four-color RGBW lamp bead. The three-color RGB lamp beads include three basic colors of red, green, and blue, which may be mixed together according to different brightness ratios to form multiple colors. The four-color RGBW lamp bead includes four colors of red, green, blue, and white. Various lighting effects can be manufactured by controlling the mixing ratio of the four colors, including white light, colored light and warm color light. Compared with the monochromatic LED lamp bead, the multi-color lamp bead includes several LED chips, which can realize accurate color adjustment by controlling the brightness of each LED chip.

In some examples, the brightness may be adjusted by directly adjusting the current of each LED chip. In some other examples, the brightness and color of the LED may be adjusted by using a PWM (Pulse Width Modulation) wave. The PWM wave outputs a constant magnitude of current. The time of the output current as a percentage of the total time (duty cycle) is regulated by switching the switch at a high frequency. The high frequency switching output from the switch in the PWM makes it impossible for the human eye to recognize the switching of the LEDs, only the change in overall brightness is visible. The greater the duty cycle, the greater the brightness of the LED. Since this relationship is a linear relationship, it is easier to adjust the LED accurately by using PWM. As for color switching, the color order of the PWM wave may be set to a corresponding value of a next color, thus enabling different colors.

FIG. 7 shows a schematic diagram of a light-emitting glass assembly 610 according to an embodiment of the present disclosure. The light-emitting glass assembly 610 includes a glass substrate 611, a light-emitting element 612, and a control unit (not shown) . The glass substrate 611 includes at least one surface. The light-emitting element 612 is disposed inside or on at least one surface of the glass substrate 611. The light-emitting element 612 is an active light-emitting element, such as an OLED module. The light-emitting element 612 can emit light from at least one surface of the glass substrate 611 to present a light-emitting pattern. The dashed lines in FIG. 7 represent the grouping of the light-emitting patterns on the glass substrate.

In some examples, the light-emitting glass assembly 610 includes at least one sensor unit 614, which may receive a human body detection signal to control the light-emitting state of the OLED module. In some other examples, the OLED module may also be adjusted by touch.

In the example of FIGs. 6 and 7, the light-emitting pattern on the light-emitting glass assembly is controlled uniformly. For example, when the human body detection signal indicates the presence of the human body, all parts of the light-emitting element are turned on,and the entire light-emitting pattern is illuminated at the same time. In some embodiments, the pattern regions and the light-emitting element may be controlled in groups, that is, the pattern regions and the light-emitting element respectively include multiple groups, and each group of patterns corresponds to each light-emitting element group one by one.
The light-emitting elements are configured to illuminate each corresponding group of light-
emitting patterns.

Specifically, the pattern regions may be evenly divided, such as by dividing the entire pattern region into multiple groupings according to equal parts of the area. Alternatively, the pattern regions may be divided according to its components. For example, the strip-shaped pattern region may be equally divided into multiple groups of sub-pattern regions with the same length. In some examples, grouping may also be performed according to the complexity of the pattern region. For example, the grouping for more complex pattern region is finer. Specifically, the complexity of the pattern region may mean that there are more patterns per unit area or more lines/types of patterns per unit area.

Correspondingly, when the pattern regions are evenly divided, the light-emitting elements may also be uniformly laid out. For example, for the strip-shaped pattern region, the light-emitting element may be linearly arranged, and each group of the light-emitting element may include an equal number of light-emitting sub-units, such as LED lamp beads. For the case where the pattern regions are divided according to complexity, the number of light-emitting sub-units in each group of the light-emitting element corresponding to a more complex pattern region may be set to be larger, that is, the light-emitting element in the more complex pattern region is denser.

In some embodiments, the sensor unit may be disposed at the peripheral edge of the light-emitting glass. In some examples, when the light-emitting glass assembly is applied to a door glass/sunroof, the sensor unit may be disposed in a window frame around the door glass, and the sensor unit is invisible from a perspective outside the window frame. The sensor unit collects the human body detection signal at the glass, especially in the pattern region. In a scenario in which the light-emitting glass assembly is applied to door glass, when a hand of a human body approaches, a part of the hand approaches the pattern region on the glass substrate, and another part of the hand approaches the sensor unit located in the window frame, for example, a sensor unit inside the door frame. The sensor unit may thus collect the human body detection signal at or near the glass substrate.

In some examples, the sensor unit may include multiple groups of sensor sub-units, and each group of sensor sub-units is configured to receive a nearby human body detection signal. The multiple groups of sensor sub-units correspond to the multiple groups of pattern regions, and their positions are as close as possible. Each group of sensor sub-units collects a human body detection signal at a corresponding group of the pattern regions.

In some embodiments, the light-emitting glass assembly 600, 610 may also include a timing unit. The timing unit is configured to calculate a time interval of the signal between different groups of sensor sub-units. The control unit may adjust the light-emitting state of each light-emitting element group according to the time interval counted by the timing unit.

In some embodiments, the sensor unit includes a proximity sensor, which is configured to detect the presence of a human body near the measured object and is not in contact with the measured object. The proximity sensor may be any one of a capacitive proximity sensor, an infrared sensor, a radar sensor, a laser sensor, or an ultrasonic sensor.

In some examples, the proximity sensor is the infrared sensor, and the detection of a human body is implemented by using infrared technology. An infrared emitter and a receiver are built into the infrared sensor. The emitter is configured to continuously emit infrared rays to the periphery and convert the infrared rays into electrical signals when receiving the infrared rays that bounce back. Since the temperature of the human body is usually higher than the ambient temperature, the human body will emit infrared rays in the air. The infrared signal received by the infrared sensor will be higher than the ambient environment when the human body approaches, so that the presence or absence of the human body can be determined accordingly. The infrared sensor has good stability and a high response speed and can detect and feedback a detection result within a millisecond level.

In some examples, the proximity sensor is the laser sensor. A detection distance may be set. When it is detected that the laser sensor is blocked within the detection distance, it may be considered that a human body is detected.

The sensor unit may output high and low level signals to the control unit according to the detected human body detection signal. For example, when the human body is detected, the sensor unit sends a high-level signal to the control unit, and the control unit outputs the high-level signal to control the switch of the light-emitting element.

In some embodiments, the sensor unit may include a distance sensor in addition to the proximity sensor. When the human body detection signal collected by the proximity sensor indicates the presence of a human body near the light-emitting glass, the pattern region is illuminated. After the pattern region is illuminated, the distance sensor is used to continuously detect the distance from the human body. The distance sensor may be at least one of a laser distance sensor, an ultrasonic distance sensor, an infrared ranging sensor, and a time-of-flight sensor. The distance sensor transmits the collected distance to the control unit to adjust the turn-on state of the light-emitting element.

In some embodiments, the sensor unit may further include a gesture sensor. When the human body detection signal collected by the proximity sensor or the gesture sensor indicates the presence of a human body near the light-emitting glass, the pattern region is illuminated. After the pattern region is illuminated, the gesture sensor is used to continuously detect a gesture motion near the pattern region. When the gesture motion meets the predetermined requirement, the gesture sensor transmits the collected signal that the gesture motion meets the requirement to the control unit to adjust the on state of the light-emitting element.

The present disclosure also relates to a vehicle including a control unit of a light-emitting glass according to any of the various embodiments of the present disclosure or a light-emitting glass assembly according to any of the various embodiments of the present disclosure.

The present disclosure further provides a computer program product, which is tangibly stored on a computer-readable storage medium and includes computer-executable instructions, and the computer-executable instructions, when executed, cause at least one processor to perform the control method for the light-emitting glass assembly in various embodiments of the present disclosure.

FIG. 8 shows a schematic diagram of a light-emitting control apparatus 700 according to another embodiment of the present disclosure. It should be understood that the light-emitting control apparatus 700 may be implemented to implement the functions of the control method for the light-emitting glass assembly 200, 210, or 300 in any one of FIGs. 2 to 4. As can be seen from FIG. 8, the light-emitting control apparatus 700 includes a central processing unit (CPU) 701 (e.g., a processor) , which may perform various appropriate actions and processing according to computer program instructions stored in a read-only memory (ROM) 702 or computer program instructions loaded into a random access memory (RAM) 703 from a storage unit 708. In the RAM 703, various programs and data required for the operation of the apparatus 700 may also be stored. The CPU 701, the ROM 702, and the RAM 703 are connected to each other through a bus 704. An input/output (I/O) interface 705 is also connected to the bus 704.

Components in the light-emitting control apparatus 700 are connected to the I/O interface 705, including: an input unit 706, such as a keyboard and a mouse; an output unit 707, such as various types of displays and speakers; a storage unit 708, such as a magnetic disk and an optical disk; and a communication unit 709, such as a network card, a modem, and a wireless communication transceiver. The communication unit 709 allows the light-emitting control apparatus 700 to exchange information/data with other devices through a computer network such as the Internet and/or various telecommunication networks.

The various methods described above, such as the control method for the light-emitting glass assembly, may be executed by the processing unit 701. For example, in some embodiments, the control method for the light-emitting glass assembly may be implemented as a computer software program, which is tangibly included in a machine-readable medium, such as the storage unit 708. In some embodiments, part or all of the computer program may be loaded and/or installed on the light-emitting control apparatus 700 via the ROM 702 and/or the communication unit 709. When the computer program is loaded into RAM 703 and executed by CPU 701, one or more actions or steps in the method described above may be performed.

In summary, in the technical solution according to the present disclosure, the control method for the light-emitting glass assembly and the light-emitting control unit according to the present disclosure determine the light-emitting state of the light-emitting element according to the human body detection signal at the glass substrate, which can improve the driving safety and increase the interaction with passengers.

Although it is described above that various exemplary embodiments of the present disclosure may be implemented in hardware or dedicated circuits, the above control apparatus may be implemented in the form of hardware or software, because in the 1990s, it can be easily determined whether a technical improvement belongs to a hardware improvement (for example, an improvement to a circuit structure such as a diode, atransistor, or a switch) or a software improvement (for example, an improvement to a method flow) . However, with the continuous development of technology, the improvements of many current method flows may almost be implemented by programming the improved method flows into a hardware circuit, in other words, by programming different programs for the hardware circuit to obtain a corresponding hardware circuit structure, that is, the hardware circuit structure is changed, so the improvements of such method flows can also be regarded as direct improvements of the hardware circuit structure. Therefore, an improvement of a method procedure cannot be implemented by using a hardware entity module. For example, a programmable logic device (PLD) (for example, a field programmable gate array (FPGA) ) is such an integrated circuit, and a logic function of the PLD is determined by a user by programming the device. A designer performs self-programming to “integrate” a digital system on a programmable logic device without requiring a chip manufacturer to design and manufacture a dedicated integrated circuit chip. Moreover, today, instead of manually manufacturing an integrated circuit chip, the programming is mostly implemented by a “logic compiler” software, which is similar to the software compiler used during program development and writing. The original code to be compiled is also written by a specific programming language, which is called hardware description language (HDL) . But HDL is not only a kind, but many kinds, such as Advanced Boolean Expression Language (ABEL) , Altera Hardware Description Language (AHDL) , Confluence, Cornell University Programming Language (CUPL) , HDCal, Java Hardware Description Language (JHDL) , Lava, Lola, MyHDL, PALASM, Ruby Hardware Description Language (RHDL) , etc. Most commonly used are Very-H-Speed Integrated Circuit Hardware Description Language (VHDL) and Verilog. It should also be clear to those skilled in the art that the hardware circuit for implementing the logic method flow can be easily obtained by only programming the method flow in the above several hardware description languages for logic programming and programming into the integrated circuit.

The computer-readable program instructions or the computer program product for executing various embodiments of the present disclosure may also be stored in the cloud. When needing to be invoked, the user may access the computer-readable program instructions stored in the cloud for executing one embodiment of the present disclosure through the mobile Internet, the fixed network, or other networks, thereby implementing the technical solutions of the present disclosure according to various embodiments of the present disclosure.

Various modifications and changes may be made to the embodiments of the present disclosure by those skilled in the art. Any modification, equivalent replacement, or improvement made without departing from the spirit and principle of the embodiments of the present disclosure shall fall within the protection scope of the embodiments of the present disclosure.
