Description

Technical Field

[0001] This application relates to the field of lighting dimming technology, specifically to a vehicle, vehicle lighting fixtures, and a control method thereof. Background Technology

[0002] As ambient lighting becomes more widely used in vehicles, it has evolved from a simple decorative function into an "emotional interactive interface" for smart cockpits, enhancing the technological feel and human-computer interaction quality of smart cockpits by providing different lighting effects.

[0003] Currently, most vehicle lights on the market are designed with a dot matrix light source. The lighting effect is achieved by adjusting the brightness of individual LEDs in the dot matrix light source. The number of light sources in the lights is large, and the lighting effect is relatively simple. Summary of the Invention

[0004] This application discloses a vehicle, vehicle lights, and a control method thereof, which can achieve a rich variety of individual light emission modes based on a small number of light sources, thereby enhancing the immersive experience for occupants.

[0005] The first aspect of this application discloses a vehicle lighting fixture, including:

[0006] Optical guide,

[0007] A first light-emitting element is disposed at one end of the light guide and is used to provide light of a first color to the light guide.

[0008] The second light-emitting element, located at the other end of the light guide, is used to provide a second color of light to the light guide.

[0009] The control module is used to control and adjust the light-emitting areas of the first light-emitting element and the second light-emitting element according to the light emission request. The first area lit by the first light-emitting element in the light guide and the second area lit by the second light-emitting element in the light guide overlap to form an overlapping section.

[0010] In some embodiments, the control module controls the adjustment of the current intensity percentage of the first light-emitting element and the second light-emitting element to adjust their light-emitting areas.

[0011] In some embodiments, the percentage value of the current intensity of the first light-emitting element is in the range of 0% to 100%, and the percentage value of the luminance of the second light-emitting element is in the range of 0% to 100%, and the sum of the percentage values ​​of the current intensity of the first light-emitting element and the second light-emitting element is 100%. The percentage value of the current intensity is the percentage of the real-time current intensity of the light-emitting element to its preset threshold current intensity. The threshold current intensity is configured to cause the light-emitting areas of the first light-emitting element and the second light-emitting element to overlap to form an overlapping segment.

[0012] In some embodiments, the overlapping segment moves in a specific direction within the vehicle lighting fixture.

[0013] In some embodiments, multiple vehicle lights are arranged in combination within the vehicle cabin, surrounding the dashboard and doors.

[0014] Furthermore, the overlapping segment of each vehicle light fixture moves from one end of the light guide along a specific direction to the other end of the light guide to achieve the effect of flowing light emission from the overlapping segments of multiple vehicle lights. It can be understood that the multiple vehicle lights include the first vehicle light fixture, the second vehicle light fixture, ..., the Nth vehicle light fixture, where N is a positive integer greater than or equal to 2. For ease of understanding, the light guides and corresponding overlapping segments contained in each vehicle light fixture are named according to the vehicle light fixture itself: the light guide in the first vehicle light fixture is called the first light guide, and the overlapping segment corresponding to the first light guide is called the first overlapping segment; the light guide in the second vehicle light fixture is called the second light guide, and the overlapping segment corresponding to the second light guide is called the second overlapping segment; and so on. In this process, the first overlapping segment of the first vehicle's lamp moves from one end of the first light guide along a specific direction to the other end of the first light guide; the second overlapping segment of the second vehicle's lamp moves from one end of the second light guide along a specific direction to the other end of the second light guide; and so on, until the Nth overlapping segment of the Nth vehicle moves from one end of the Nth light guide along a specific direction to the other end of the Nth light guide, thereby achieving the effect of flowing light emission from the first overlapping segment, the second overlapping segment, and so on, to the Nth overlapping segment.

[0015] In some embodiments, the light emission request includes light flow direction information and light flow speed information.

[0016] Furthermore, when the vehicle is traveling at a constant speed, the speed of the light stream is constant; when the vehicle accelerates or decelerates, the acceleration of the light stream is positively correlated with the vehicle's acceleration.

[0017] In some embodiments, the vehicle lights include multiple sets of light-emitting elements.

[0018] Furthermore, the threshold current intensities of multiple sets of light-emitting elements are configured to be the same or different.

[0019] Furthermore, the colors of multiple light-emitting elements are configured to be the same or different.

[0020] The second aspect of this application discloses a vehicle lighting control method for controlling the vehicle lighting of the aforementioned first aspect, comprising: acquiring a light emission request; and, according to the light emission request, controlling and adjusting the light emission areas of a first light-emitting element and a second light-emitting element, wherein a first area lit by the first light-emitting element in a light guide and a second area lit by the second light-emitting element in a light guide overlap to form an overlapping segment.

[0021] The third aspect of this application discloses a vehicle including at least one of the vehicle lights mentioned in the first aspect.

[0022] The vehicle, vehicle lights, and control method provided in this application control the position and movement of overlapping sections in the vehicle lights by dynamically adjusting the luminous areas of the first and second luminous elements, configuring different light source colors, and achieving rich individual light emission modes based on only a few light sources. Multiple vehicle lights work together to achieve vehicle cabin lighting modes, enhancing the occupant's immersion. The interactivity of the vehicle lighting modes is improved by linking light control with driving data. Attached Figure Description

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0032] It should be noted that although functional modules are divided in the device schematic diagram and a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first," "second," etc., in the specification, claims, and the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0033] 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 this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0034] Currently, vehicle ambient lighting designs are typically static, using direct light strips or indirect light projection. The ambiance and interaction of ambient lighting are mostly limited to basic modes. A few models feature music-inspired ambient lighting, which can enhance some interactions between users and the lighting. However, overall, they do not adequately fulfill the function of modern intelligent cockpit ambient lighting as an "emotional interactive interface" for users. Furthermore, current vehicle lighting fixtures on the market are usually designed with dot matrix light sources. To achieve a flowing effect throughout the vehicle, lights need to be arranged in a ring around the entire cabin. The changing lighting effects are achieved by adjusting the brightness of individual LEDs in the dot matrix light source. This results in a large number of light sources, complex control schemes, and high lighting costs.

[0035] Based on this, this application provides a vehicle lighting fixture that aims to achieve rich lighting effects with fewer light sources, simplify the control scheme, and improve interactivity with occupants.

[0036] Specifically, the vehicle lights include:

[0037] Optical guide,

[0038] A first light-emitting element is disposed at one end of the light guide and is used to provide light of a first color to the light guide.

[0039] The second light-emitting element, located at the other end of the light guide, is used to provide a second color of light to the light guide.

[0040] The control module is used to control and adjust the light-emitting areas and / or light-emitting brightness of the first light-emitting element and the second light-emitting element according to the light-emitting request. The first area lit by the first light-emitting element in the light guide overlaps with the second area lit by the second light-emitting element in the light guide to form an overlapping segment.

[0041] The light emission request is generated by a preset trigger event or by the user's real-time operation behavior.

[0042] In some embodiments, the control module controls the adjustment of the current intensity percentage of the first light-emitting element and the second light-emitting element to adjust their light-emitting area and / or light brightness. The current intensity percentage is the percentage of the real-time current intensity of the light-emitting element to its preset threshold current intensity, which is configured to cause the light-emitting areas of the first light-emitting element and the second light-emitting element to overlap to form an overlapping segment.

[0043] Please refer to Figure 1 The vehicle lighting fixture includes a light guide and a set of light sources A and B distributed at opposite ends of the light guide. Light source A serves as the first light-emitting element, and light source B serves as the second light-emitting element. Light source A illuminates a region D1 a certain distance from its distributed end within the light guide, and light source B illuminates a region D2 a certain distance from its distributed end within the light guide. A threshold current intensity is set for light sources A and B, causing the illuminated regions D1 and D2 of light sources A and B to overlap, forming an overlapping segment D.

[0044] This application embodiment controls the position and movement of the overlapping section in the vehicle lamp by dynamically adjusting the light-emitting areas of the first and second light-emitting elements, configuring different light source colors, achieving rich lighting effects with only a small number of light sources, and reducing lamp costs.

[0045] In some embodiments, the percentage value of the current intensity of the first light-emitting element ranges from 0% to 100%, the percentage value of the luminance of the second light-emitting element and the percentage value of the current intensity ranges from 0% to 100%, and the sum of the percentage values ​​of the current intensity of the first light-emitting element and the second light-emitting element is 100%.

[0046] For reference Figure 1 As shown, the percentage of the real-time current intensity of the light source to the aforementioned threshold current intensity is the percentage of the current intensity of the light source. The percentage values ​​of the current intensity of light source A and light source B are both between 0% and 100%, and the sum of the percentage values ​​of the current intensity of light source A and light source B is 100%. The areas illuminated by light source A and light source B in the light guide always overlap and form an overlapping segment D. By dynamically controlling the percentage of the current intensity of light source A and light source B, the overlapping segment D can be moved in the vehicle lamp.

[0047] In some embodiments, the overlapping segment moves unidirectionally in a specific direction within the vehicle lamp. The first and second light-emitting elements are configured to be the same color, and the two light-emitting elements form a monochromatic overlapping segment in the light guide. The monochromatic overlapping segment moves within the light guide when the current intensity percentage of the light-emitting elements is dynamically adjusted. In some embodiments, as the current intensity percentage of the first light-emitting element gradually increases from 0% to 100%, the monochromatic overlapping segment gradually moves from one end of the vehicle lamp adjacent to the first light-emitting element to the other end of the vehicle lamp to achieve a flowing light effect.

[0048] In another embodiment, the light sources in the two light-emitting elements are configured to be different colors, and the two light-emitting elements form a gradient overlapping section in the light guide. When the current intensity percentage of the light-emitting elements is dynamically adjusted, the gradient overlapping section moves in the light guide. In some embodiments, when the current intensity percentage of the light source at one end of the light guide gradually increases from 0% to 100%, the gradient overlapping section gradually moves from one end of the vehicle lamp adjacent to the first light-emitting element to the other end of the vehicle lamp to achieve a flowing light effect.

[0049] In other embodiments, the overlapping segment D does not move in one direction, and this application does not impose any restrictions on this.

[0050] In some embodiments, vehicle lights are provided with multiple sets of light-emitting elements, such as Figure 2 As shown, the vehicle lighting fixture includes four light guides and light sources distributed at both ends of them. Light sources A1, A2, A3, and A4 are configured to be blue, while light sources B1, B2, B3, and B4 are configured to be red. The threshold current intensities of light source groups A1-B1, A2-B2, A3-B3, and A4-B4 are configured to be the same. The current intensity percentages of the four light source groups are controlled to be 80%, 20%, 60%, 40%, 40%, 60%, 20%, and 80%, respectively, so that the corresponding overlapping segments D1, D2, D3, and D4 are in different positions.

[0051] In some embodiments, different threshold current intensities are set among multiple groups of light-emitting elements, so that the light emission intensity is different in different light guides.

[0052] In some embodiments, different colors are set among multiple groups of light-emitting elements, so that different light-emitting colors are emitted in different light guides.

[0053] This application's embodiments can achieve rich lighting display effects by combining different light source colors and threshold current intensity settings, as well as dynamically adjusting the percentage of the combined current intensity of multiple groups of light-emitting elements. In some embodiments, multiple groups of light-emitting elements are also distributed at both ends of a single light guide, which is not a limitation of this application.

[0054] In some embodiments, multiple vehicle lights are used in combination, with several vehicle lights installed in the vehicle cabin. These multiple vehicle lights work together to achieve different lighting modes, enhancing the immersive experience for passengers.

[0055] Please refer to Figure 3 As shown, several vehicle lights are arranged around the dashboard, front door, and rear door within the vehicle cabin, forming a relay route.

[0056] In some embodiments, the light emission mode is a relay flow mode, meaning that in several vehicle lights, the overlapping segment of each vehicle light moves from one end of the light guide along a specific direction to the other end of the light guide, thereby achieving the effect of flowing light emission from the overlapping segments of multiple vehicle lights. It can be understood that the multiple vehicle lights include the first vehicle light, the second vehicle light, ..., the Nth vehicle light, where N is a positive integer greater than or equal to 2. For ease of understanding, the light guide and corresponding overlapping segment contained in each vehicle light are named according to the vehicle light itself: the light guide in the first vehicle light is called the first light guide, and the overlapping segment corresponding to the first light guide is called the first overlapping segment; the light guide in the second vehicle light is called the second light guide, and the overlapping segment corresponding to the second light guide is called the second overlapping segment; and so on. For example, the percentage of the current intensity of the light-emitting element at one end of the first vehicle lamp gradually increases from 0% to 100%. After the first overlapping segment moves from one end of the first vehicle lamp adjacent to the light-emitting element to the other end of the first vehicle lamp, the percentage of the light source current intensity of the adjacent second vehicle lamp adjacent to the first vehicle lamp gradually increases from 0% to 100%. The second overlapping segment moves from one end of the second vehicle lamp adjacent to the first vehicle lamp to the other end of the second vehicle lamp, and so on, to achieve a flowing light effect on the relay route of the vehicle lamps in the vehicle cabin, that is, a flowing light effect.

[0057] Optionally, the light emission request includes light flow direction information and light flow speed information. The light flow direction information is used to indicate the flow direction of the indicator light; the light flow speed information is used to indicate the flow speed of the indicator light.

[0058] In some embodiments, the direction of light flow is consistent with the direction of vehicle travel.

[0059] In some embodiments, when the vehicle is traveling at a constant speed, the speed of the light stream is constant; when the vehicle accelerates or decelerates, the acceleration of the light stream is positively correlated with the vehicle acceleration.

[0060] The above content will be described below with reference to specific embodiments, as shown in Figures 4(a), 4(b), and 4(c):

[0061] In the first round of display, the light sources at A1, A3, A5, B1, B3, and B5 were configured to display blue light, while the light sources at A2, A4, A6, B2, B4, and B6 were configured to display red light. The percentage of the current intensity of the light sources at A1 and B1 increased synchronously and uniformly from 0% to 100%, while the percentage of the current intensity of the light sources at A2 and B2 decreased synchronously and uniformly from 100% to 0%. When the percentage of light source current intensity at points A2 and B2 drops to 0%, the percentage of light source current intensity at points A3 and B3 simultaneously and uniformly increases from 0% to 100%, while the percentage of light source current intensity at points A4 and B4 simultaneously and uniformly decreases from 100% to 0%. When the percentage of light source current intensity at points A4 and B4 drops to 0%, the percentage of light source current intensity at points A3 and B3 simultaneously and uniformly increases from 0% to 100%, while the percentage of light source current intensity at points A5 and B5 simultaneously and uniformly decreases from 100% to 0%. This achieves the simultaneous movement of the blue-red gradient overlapping segment from A1 to A6 and from B1 to B6, creating a uniform flow from the steering wheel towards the rear of the vehicle on both sides. When the blue-red gradient overlapping segment reaches points A6 and B6, the first round of display ends, and the second round of display begins.

[0062] In the second round of display, the light sources at A1, A3, A5, B1, B3, and B5 are configured to display orange light, while the light sources at A2, A4, A6, B2, B4, and B6 are configured to display blue light. Each light source follows the same percentage change in current intensity as in the first round of display, simultaneously moving the orange-blue gradient overlapping sections from A1 to A6 and from B1 to B6, creating a flow from the steering wheel to the rear of the car on both sides. Subsequently, a new color flowing light display is cycled on from A1 and B1.

[0063] In some embodiments, the acceleration of the percentage change in light source current intensity at various locations is positively correlated with the vehicle acceleration, making the light flow acceleration positively correlated with the vehicle acceleration. A throttle signal is introduced to control the percentage change in light source current intensity. After entering the driving linkage mode, when the vehicle is stationary, the percentage change in light source current intensity changes at a constant speed. When the vehicle starts, a gain is applied to the acceleration of the percentage change in light source current intensity based on the throttle parameters, and a negative gain is applied based on the braking parameters, thereby achieving the driving linkage effect. The interactivity of the vehicle's lighting mode is improved by linking light control with driving data.

[0064] This application also provides a vehicle lighting control method for controlling the aforementioned vehicle lights. For example... Figure 5 As shown, the vehicle lighting control method includes:

[0065] S501, Obtain the light emission request.

[0066] S502. According to the light emission request, control and adjust the light emission areas of the first light emission element and the second light emission element, and the first area lit by the first light emission element in the light guide and the second area lit by the second light emission element in the light guide overlap to form an overlapping section.

[0067] In some embodiments, controlling the light-emitting area of ​​the first light-emitting element and the second light-emitting element includes: controlling the current intensity percentage of the first light-emitting element and the second light-emitting element to adjust their light-emitting areas, wherein the current intensity percentage is the percentage of the real-time current intensity of the light-emitting element to its preset threshold current intensity, and the threshold current intensity is configured to cause the light-emitting areas of the first light-emitting element and the second light-emitting element to overlap to form an overlapping segment.

[0068] In some embodiments, the percentage value of the current intensity of the first light-emitting element ranges from 0% to 100%, and the percentage value of the luminance of the second light-emitting element and the percentage value of the current intensity ranges from 0% to 100%, and the sum of the percentage values ​​of the current intensity of the first light-emitting element and the second light-emitting element is 100%.
