Description

Projection modules, vehicle lighting devices and vehicles

[0001] This application claims priority to Chinese Patent Application No. 202420869241.9, filed on April 24, 2024, entitled “Projection Module, Vehicle Lighting Device and Vehicle”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of transportation technology, and in particular to a projection module, a vehicle lighting device, and a vehicle. Background Technology

[0003] With the innovation and development of automotive technology, automotive lighting systems have evolved from simple illumination to include personalized designs, safety features, and interactive elements, improving driving safety and enhancing the user experience through entertainment projection. In related technologies, the lighting system includes a left front light and a right front light. The left front light is mounted on the front left of the vehicle, and the right front light on the front right. Both the left and right front lights include a low beam module, a high beam module, and a projection module. The low beam module provides the low beam function, the high beam module provides the high beam function, and the two projection modules work together to emit a projection beam and achieve interactive / entertainment projection functions. However, due to the high cost of the projection module, and the requirement of using two projection modules, the overall cost of the lighting system is high.

[0004] Summary of the Invention

[0005] This application provides a projection module, a vehicle lighting device, and a vehicle, which can reduce the number of projection modules and lower the cost of the vehicle lighting device.

[0006] This application provides a vehicle lighting device, including a first vehicle lamp and a second vehicle lamp, both mounted on the same vehicle. The first vehicle lamp includes an illumination module and a projection module, and the second vehicle lamp includes an illumination module and a companion module. The illumination modules in the first and second vehicle lamps are symmetrically arranged, with the illumination module emitting a first illumination beam. The projection module and companion module are symmetrically arranged, with the projection module emitting an imaging beam to form an image, and the companion module emitting a second illumination beam.

[0007] The vehicle lighting device provided in this application embodiment projects icons, images, videos, and other content using a high-resolution projection module, fulfilling both interactive and projection needs and improving driving safety. Additionally, lighting can be achieved through at least one of a lighting module, a projection module, and a companion module to meet lighting requirements. Furthermore, while the lighting module fulfills lighting needs, the projection module and / or companion module can enhance the lighting, further improving driving safety.

[0008] Since only one projection module is used, the cost of the vehicle lighting system can be reduced while still meeting projection and interaction requirements. Furthermore, by working together with the companion module and the projection module, the functional needs of the vehicle lighting system in various scenarios can be met.

[0009] In one possible implementation, the lighting module includes a low beam mode, wherein when the lighting module is in low beam mode, a first lighting beam is used to achieve low beam illumination.

[0010] This allows for lighting in environments with poor visibility (such as nighttime or dimly lit environments), improving driving safety.

[0011] In one possible implementation, the lighting module further includes a first high beam mode, in which a first lighting beam is used to achieve high beam illumination when the lighting module is in the first high beam mode.

[0012] This provides long-range lighting in environments with poor visibility (such as nighttime or dimly lit environments), increasing the driver's field of vision.

[0013] In one possible implementation, when the lighting module is in a first high beam mode, the first lighting beam is used to achieve adaptive high beam lighting.

[0014] In this way, the illumination range of the lighting module can be automatically adjusted according to the position and distance of oncoming vehicles, and the lighting command for the area of ​​oncoming vehicles can be turned off or dimmed, thereby reducing glare from oncoming vehicles and maximizing the driver's visibility needs.

[0015] In one possible implementation, both the first and second headlights further include a high beam module, with the high beam modules in the first and second headlights arranged symmetrically, and the high beam modules used to provide high beam illumination.

[0016] This provides long-range lighting in environments with poor visibility (such as nighttime or dimly lit environments), increasing the driver's field of vision.

[0017] In one possible implementation, the high beam module is used to achieve adaptive high beam illumination.

[0018] In this way, the high beam module can automatically adjust its illumination range based on the position and distance of oncoming vehicles, and turn off or dim the headlights in the area of ​​oncoming vehicles, thereby reducing glare from oncoming vehicles and maximizing the driver's visibility.

[0019] In one possible implementation, the companion module also includes a second high beam mode, in which a second illumination beam is used to achieve high beam illumination when the companion module is in the second high beam mode.

[0020] This provides long-range lighting in environments with poor visibility (such as nighttime or dimly lit environments), increasing the driver's field of vision.

[0021] In one possible implementation, when the companion module is in the second high beam mode, the second illumination beam is used to achieve adaptive high beam illumination.

[0022] In this way, the illumination range of the companion module can be automatically adjusted according to the position and distance of oncoming vehicles, and the light illumination command of the oncoming vehicle area can be turned off or dimmed, thereby reducing glare from oncoming vehicles and maximizing the driver's visibility needs.

[0023] In one possible implementation, the companion module includes a low beam assist mode, in which a second illumination beam is used to achieve low beam assist illumination when the companion module is in low beam assist mode.

[0024] In this way, when the lighting module provides low beam illumination, the companion module emits light to enhance low beam illumination, which can further improve driving safety.

[0025] In one possible implementation, the companion module includes a high beam assist mode, in which a second illumination beam is used to achieve high beam assist lighting when the companion module is in high beam assist mode.

[0026] In this way, when the high beam module or the lighting module is providing high beam illumination, the companion module emits light, which can enhance the high beam illumination and help to further improve driving safety.

[0027] In one possible implementation, the companion module includes a flashing mode, in which the companion module emits a second illumination beam multiple times at intervals within one cycle.

[0028] In this way, the companion module emits light intermittently within a cycle, which can warn targets and improve the safety of drivers and pedestrians outside the vehicle, as well as enhance the aesthetics of the vehicle. At the same time, it eliminates the need to increase the number of modules in the vehicle's lighting system, thus helping to reduce the cost of the lighting system.

[0029] In one possible implementation, the companion module includes a blind spot fill light mode, in which a second illumination beam is used to achieve blind spot illumination when the companion module is in blind spot fill light mode.

[0030] In this way, without increasing the number of modules in the headlight assembly, driving safety can be further improved, while the cost of the headlight assembly can be reduced.

[0031] In one possible implementation, the vehicle lighting device further includes a controller electrically connected to both the projection module and the companion module. The controller is used to control the projection module to emit an imaging beam, and / or, the controller is used to control the companion module to emit a second illumination beam.

[0032] In one possible implementation, the vehicle lighting device further includes a controller electrically connected to both the projection module and the companion module. The controller is used to control the projection module to emit an imaging beam based on sensing information output by the sensing module, and / or, the controller is used to control the companion module to emit a second illumination beam based on the sensing information output by the sensing module.

[0033] In this way, the controller can control the projection module and / or companion module to emit light based on the sensing information, so that the advantages of the projection module and companion module complement each other, and meet the functional requirements of smart vehicle lights in multiple scenarios with the fewest number of modules.

[0034] In one possible implementation, at least one of the first and second headlights further includes a sensing module electrically connected to the controller.

[0035] In one possible implementation, the vehicle lighting device includes two controllers, one controller for controlling the projection module to emit an imaging beam based on the sensing information output by the sensing module, and the other controller for controlling the companion module to emit a second illumination beam based on the sensing information output by the sensing module.

[0036] In this way, based on the control of the projection module and the companion module, the performance of the controller can be reduced, thereby reducing the cost of the controller, and consequently reducing the cost of the vehicle lighting device.

[0037] In one possible implementation, the projection module includes a projection mode and an illumination mode. When in projection mode, the projection module emits an imaging beam. When in illumination mode, the projection module emits a third illumination beam, which is used for auxiliary illumination.

[0038] In this way, in addition to realizing the projection function, the projection module can also provide auxiliary lighting such as low beam auxiliary lighting, high beam auxiliary lighting, or blind spot lighting in the lighting scene, thereby further improving the range or brightness of the lighting, and thus further improving the lighting effect of smart lighting.

[0039] In one possible implementation, the vehicle lighting device includes a first mode, a second mode, a third mode, a fourth mode, a fifth mode, a sixth mode, and a seventh mode. In the first mode, the projection module emits an imaging beam. In the second mode, the lighting module emits a first illumination beam. In the third mode, the companion module emits a second illumination beam. In the fourth mode, the projection module emits an imaging beam, and the lighting module emits the first illumination beam. In the fifth mode, the lighting module emits the first illumination beam, and the companion module emits the second illumination beam. In the sixth mode, the projection module emits an imaging beam, the lighting module emits the first illumination beam, and the companion module emits the second illumination beam. In the seventh mode, the projection module emits an imaging beam, and the companion module emits the second illumination beam.

[0040] In this way, by having the light emitted from the projection module, lighting module, and companion module work together, three major functional scenarios—intelligent lighting, intelligent interaction, and intelligent projection—can be achieved with the fewest possible modules. This can improve driving safety on the one hand and enhance the user experience on the other.

[0041] A second aspect of this application provides a projection module disposed in a first vehicle headlight. The first vehicle headlight also includes an illumination module. The illumination module in the first vehicle headlight and the illumination module in a second vehicle headlight are symmetrically arranged. The illumination module is used to emit a first illumination beam. The first vehicle headlight and the second vehicle headlight are disposed on the same vehicle. The second vehicle headlight includes a companion module. The projection module and the companion module are symmetrically arranged. The projection module is used to emit an imaging beam that forms an image, and the companion module is used to emit a second illumination beam.

[0042] In one possible implementation, the projection module includes a projection mode and an illumination mode. When in projection mode, the projection module emits an imaging beam. When in illumination mode, the projection module emits a third illumination beam, which is used for auxiliary illumination.

[0043] In this way, in addition to realizing the projection function, the projection module can also provide auxiliary lighting such as low beam auxiliary lighting, high beam auxiliary lighting, or blind spot lighting in the lighting scene, thereby further improving the range or brightness of the lighting, and thus further improving the lighting effect of smart lighting.

[0044] In one possible implementation, the projection module includes a control unit for electrical connection with a controller, and the control unit and the controller are used to control the projection module to emit an imaging beam.

[0045] In this way, by setting up a control unit within the projection module, the control functions are decentralized to the projection module itself. The projection module itself has some control functions, which work together with the control functions deployed on other controllers to control the projection module.

[0046] In one possible implementation, the projection module includes a control unit for controlling the projection module to emit an imaging beam based on sensing information.

[0047] In this way, the projection module itself has control functions, and can control the projection module to emit an imaging beam based on the perceived information.

[0048] In one possible implementation, the lighting module includes a low beam mode, wherein when the lighting module is in low beam mode, a first lighting beam is used to achieve low beam illumination.

[0049] In one possible implementation, the lighting module further includes a first high beam mode, in which a first lighting beam is used to achieve high beam illumination when the lighting module is in the first high beam mode.

[0050] In one possible implementation, the companion module also includes a second high beam mode, in which a second illumination beam is used to achieve high beam illumination when the companion module is in the second high beam mode.

[0051] In one possible implementation, the companion module includes a low beam assist mode, in which a second illumination beam is used to achieve low beam assist illumination when the companion module is in low beam assist mode.

[0052] In one possible implementation, the companion module includes a high beam assist mode, in which a second illumination beam is used to achieve high beam assist lighting when the companion module is in high beam assist mode.

[0053] A third aspect of this application provides a vehicle, including a vehicle body and a lighting device as described in any of the first aspects, the lighting device being mounted on the vehicle body.

[0054] The vehicle provided in this application embodiment can improve vehicle safety and enhance user experience by adopting intelligent vehicle lighting devices.

[0055] In one possible implementation, the vehicle lighting device includes a first vehicle light and a second vehicle light, with the first vehicle light mounted on the front left side of the vehicle body and the second vehicle light mounted on the front right side of the vehicle body, and the first and second vehicle lights are arranged symmetrically.

Detailed Implementation

[0067] Figure 1 is a schematic diagram of the architecture of a vehicle lighting system in the related art. As shown in Figure 1, the vehicle lighting system in the related art includes a left front light 200 and a right front light 300. The left front light 200 is installed at the left front of the vehicle, and the right front light 300 is installed at the right front of the vehicle. Both the left front light 200 and the right front light 300 include a low beam module 202, a high beam module 203, and a projection module 201. The two projection modules 201 are symmetrically arranged, as are the two high beam modules 203 and the two low beam modules 202. The two low beam modules 202 are used to implement the low beam function, providing low beam illumination. Both projection modules 201 are high-resolution DLP modules. DLP modules have the characteristics of high resolution and high definition. The two projection modules 201 jointly emit projection beams that overlap to achieve interactive or entertainment projection functions.

[0068] However, the projection module 201 is expensive, and the presence of two projection modules 201 contributes to the high cost of the vehicle lighting system. Furthermore, the large number of modules within the vehicle lighting system also contributes to its high cost. Therefore, how to meet the needs of multiple scenarios while reducing the cost of the vehicle lighting system has become an urgent problem to be solved.

[0069] In view of this, this application provides a projection module 40, a vehicle lighting device 110, and a vehicle 100, which meet the needs of multiple scenarios with a smaller number of modules. At the same time, the projection module 40 is only one, which can reduce the cost of the vehicle lighting device 110.

[0070] The vehicle 100 can be a car, truck, motorcycle, bus, recreational vehicle, amusement park vehicle, construction equipment, tram, etc. In this embodiment, a car is used as an example for illustration.

[0071] Figure 2 is a structural schematic diagram of a means of transportation provided in an embodiment of this application.

[0072] As shown in Figure 2, the vehicle 100 includes a body 120 and a lighting device 110. The lighting device 110 is installed on the body 120 and can realize three major functional scenarios: intelligent lighting, intelligent interaction, and intelligent projection. On the one hand, it can improve driving safety, and on the other hand, it can improve the user experience.

[0073] Intelligent lighting can include intelligent low beam and intelligent high beam. Intelligent low beam can include low beam enhancement lighting, and intelligent high beam can include high beam enhancement lighting and adaptive driving beam (ADB) scenarios.

[0074] Intelligent interaction can include driving guidance, driving prompts, and interaction. Driving guidance can include scenarios such as width guidance (light carpet), driving prompts can include scenarios such as safe distance measurement function, light navigation function, driving status warning, traffic sign reminder and road risk warning, and driving interaction can include scenarios such as driving trajectory interaction and zebra crossing information.

[0075] Smart projection can include floor projection and wall projection, and can realize scenarios such as mobile phone multimedia, in-vehicle multimedia, PC multimedia, interactive games, and welcoming guests.

[0076] For example, as shown in FIG2, the vehicle lighting device 110 can be a front light module, which is mounted at the front of the vehicle body 120. In some implementations, the vehicle lighting device 110 can also be a rear light module, which is mounted at the rear of the vehicle body 120. In other implementations, the vehicle lighting device 110 can also be a side light module, which is mounted on the left or right side of the vehicle body 120.

[0077] As shown in Figure 2, the vehicle lighting device 110 includes a first vehicle light 10 and a second vehicle light 20, which are mounted on the body 120 of the same vehicle 100. The first vehicle light 10 is installed at the front left of the body 120, and the second vehicle light 20 is installed at the front right of the body 120, arranged symmetrically. Therefore, the first vehicle light 10 can function similarly to the left front light, and the second vehicle light 20 can function similarly to the right front light. Both the first vehicle light 10 and the second vehicle light 20 possess at least low beam and high beam functions, enabling both low beam and high beam illumination to meet driving safety requirements.

[0078] Figure 3 is a schematic diagram of the architecture of the first type of vehicle lighting device provided in the embodiment of this application, and Figure 4 is a schematic diagram of the light emission of each module in the vehicle lighting device in Figure 3.

[0079] As shown in Figure 3, the first vehicle light 10 includes an illumination module 30 and a projection module 40, and the second vehicle light 20 includes an illumination module 30 and a companion module 50. The illumination modules 30 in the first and second vehicle lights 10 are symmetrically arranged, and the illumination module 30 emits a first illumination beam (as shown in Figure 4A) to meet illumination requirements. The projection module 40 and companion module 50 are symmetrically arranged, making the layout of the internal modules of the first and second vehicle lights 10 and 20 symmetrical, which can improve the aesthetics of the vehicle 100. The projection module 40 emits an imaging beam to form an image (as shown in Figure 4B). The image formed by the imaging beam can be text, pictures, video content, etc., to fulfill projection requirements. The companion module 50 emits a second illumination beam.

[0080] The symmetrical arrangement of the projection device and the companion module 50 can be understood as follows: the projection device and the companion module 50 are symmetrical in position about the center line parallel to the length direction of the vehicle 100 (as shown by X in Figure 3).

[0081] During the operation of the projection module 40, the imaging beam emitted by the projection module 40 is directed towards the front of the vehicle 100, causing the image formed by the imaging beam to be projected onto the ground and into the air. The image projected into the air primarily consists of the high beam intensity distribution information, while the image projected onto the ground may include the low beam intensity distribution information and one or more custom patterns (e.g., zebra crossings, arrows, triangles, manufacturer logos, text, etc., serving as prompts, greetings, or interactive elements). It should be understood that the imaging beam emitted by the projection module 40 can project onto walls or other locations besides the ground.

[0082] In this embodiment, the projection module 40 uses a pixelated imaging device, such as a MEMS, DMD, LCOS, LCD, or MicroLED imaging device, which makes the projection module 40 have high resolution and can realize the projection function.

[0083] The companion module 50 can also be a pixelated light module. In this case, the number of pixels in the companion module 50 is lower than that in the projection module 40, meaning the resolution of the companion module 50 is lower than that of the projection module 40. For example, the projection module 40 can be a megapixel-level module, while the companion module 50 can be a kilopixel or lower-pixel module.

[0084] In summary, the high resolution of projection module 40 gives it high-definition capabilities, enabling the projection of icons, images, or videos for intelligent interaction and projection. The lower resolution of companion module 50 provides a wide field of view and high brightness, supplementing the lighting range and brightness in lighting scenarios or providing high-beam illumination for intelligent lighting. Therefore, the symmetrical arrangement of projection module 40 and companion module 50, with complementary light patterns, ensures that the vehicle lighting device 110 meets both lighting and projection performance requirements. Furthermore, the use of only one projection module 40 and the reduction in the number of modules within the vehicle lighting device 110 reduce its cost.

[0085] As shown in Figure 3, the first vehicle light 10 may further include a first housing 11, with a projection module 40 and one of the lighting modules 30 disposed inside the first housing 11. The second vehicle light 20 may further include a second housing 21, with another lighting module 30 and a companion module 50 disposed inside the second housing 21.

[0086] Exemplarily, the vehicle lighting device 110 may include a first mode, a second mode, a third mode, a fourth mode, a fifth mode, a sixth mode, and a seventh mode. Specifically, when the vehicle lighting device 110 is in the first mode, the projection module 40 emits an imaging beam. When the vehicle lighting device 110 is in the second mode, the illumination module 30 emits a first illumination beam. When the vehicle lighting device 110 is in the third mode, the companion module 50 emits a second illumination beam. When the vehicle lighting device 110 is in the fourth mode, the projection module 40 emits an imaging beam, and the illumination module 30 emits a first illumination beam. When the vehicle lighting device 110 is in the fifth mode, the illumination module 30 emits a first illumination beam, and the companion module 50 emits a second illumination beam. When the vehicle lighting device 110 is in the sixth mode, the projection module 40 emits an imaging beam, the illumination module 30 emits a first illumination beam, and the companion module 50 emits a second illumination beam. When the vehicle lighting device 110 is in the seventh mode, the projection module 40 emits an imaging beam, and the companion module 50 emits a second illumination beam.

[0087] By controlling the emission of at least one of the projection module 40, companion module 50, and lighting module 30 within the vehicle lighting device 110, the vehicle lighting device 110 can possess multiple operating modes. With a minimal number of modules, the vehicle lighting device 110 can achieve three major functional scenarios: intelligent lighting, intelligent interaction, and intelligent projection. This improves both driving safety and user experience. Simultaneously, the reduced number of modules within the vehicle lighting device 110 reduces its cost.

[0088] It is understandable that at any given time, one of the lighting module 30, projection module 40, and companion module 50 can emit light. Alternatively, two of the lighting module 30, projection module 40, and companion module 50 can emit light. Or, all of the lighting module 30, projection module 40, and companion module 50 can emit light.

[0089] It should be noted that the number of working modes of the vehicle lighting device may also be some of the modes from the first to the seventh mode, which will not be described one by one here.

[0090] For example, as shown in FIG2, the first headlight 10 is installed at the left front of the vehicle body 120, and the second headlight 20 is installed at the right front of the vehicle body 120. Therefore, the lighting module 30 in the first headlight 10 and the second headlight 20 can both include a low beam mode. When the lighting module 30 is in the low beam mode, the lighting module 30 is functionally similar to the low beam module. At this time, the first lighting beam is used to realize low beam illumination, so that the first headlight 10 and the second headlight 20 have low beam function, which can provide lighting needs in environments with poor visibility (such as dark environments or dim environments) and improve driving safety.

[0091] It should be noted that, in addition to the low beam mode, the lighting module 30 may also include a first high beam mode in some possible implementations. When the lighting module 30 is in the first high beam mode, it functions similarly to the high beam module 80. At this time, the first illumination beam is used to achieve high beam illumination, which can provide long-distance illumination in environments with poor visibility (such as dark environments or dim environments) and increase the driver's field of vision.

[0092] In some embodiments, when the lighting module 30 is in the first high beam mode, the first illumination beam can be used to achieve adaptive high beam lighting. It can automatically adjust the illumination range of the lighting module 30 according to the position and distance of oncoming vehicles, turning off or dimming the light illumination command in the area of ​​oncoming vehicles, thereby reducing glare for oncoming vehicles while maximizing the driver's visibility. In other embodiments, when the lighting module 30 is in the first high beam mode, the first illumination beam can also be used to achieve non-adaptive high beam lighting, which can be understood as the first illumination beam being used to achieve ordinary high beam lighting.

[0093] It should also be noted that, in addition to being used as a low beam module or high beam module 80, the lighting module 30 can also be used as other types of lighting modules. For example, when the vehicle light device 110 is installed at the rear of the vehicle body 120, the first vehicle light 10 can also be the left rear light and the second vehicle light 20 can also be the right rear light. In this case, the lighting module 30 can function similarly to a brake light module. When braking, the lighting module 30 emits a first beam of light to remind vehicles behind to slow down.

[0094] In some possible implementations, the companion module 50 may include a low beam assist mode, in which the second illumination beam is used to provide low beam assist illumination (as shown in C in Figure 4).

[0095] For example, when the vehicle lighting device 110 is in the fifth mode, during the low beam illumination process of the lighting module 30, the second illumination beam cooperates with the first illumination beam to improve the range and / or brightness of the low beam illumination, thereby achieving enhanced low beam illumination.

[0096] In some possible implementations, the companion module 50 may also include a second high beam mode. When the companion module 50 is in the second high beam mode, it functions similarly to a high beam module 80. In this mode, the second illumination beam is used to achieve high beam illumination, which can provide long-distance illumination in environments with poor visibility (such as nighttime or dim environments) and increase driving visibility.

[0097] In some embodiments, when the companion module 50 is in the second high beam mode, the second illumination beam can be used to achieve adaptive high beam lighting (as shown in D in Figure 4). It can automatically adjust the illumination range of the companion module 50 according to the position and distance of oncoming vehicles, turning off or dimming the light illumination command in the area of ​​oncoming vehicles, thereby reducing glare from oncoming vehicles while maximizing the driver's visibility. In other embodiments, when the companion module 50 is in the second high beam mode, the second illumination beam can also be used to achieve non-adaptive high beam lighting, which can be understood as the first illumination beam being used to achieve ordinary high beam lighting.

[0098] It should be noted that one of the lighting module 30 and the companion module 50 has a high beam mode, while the other does not. For example, the lighting module 30 may have a first high beam mode, while the companion module 50 may not have a second high beam mode. Alternatively, while the lighting module 30 may have a first high beam mode, the companion module 50 may also have a second high beam mode. In this case, one of the first and second lighting beams is used to achieve non-adaptive high beam illumination, while the other is used to achieve adaptive high beam illumination.

[0099] In some possible implementations, the companion module 50 may also include a blind spot illumination mode, in which a second illumination beam is used to achieve blind spot illumination when the companion module 50 is in the blind spot illumination mode.

[0100] For example, when the headlight device 110 is in the fifth mode, during the low beam illumination process of the lighting module 30, the second lighting beam illuminates the area that the first lighting beam cannot reach, which can further improve the driver's field of vision and help to further improve driving safety.

[0101] In some possible implementations, the companion module 50 may also include a flashing mode, in which the companion module 50 emits a second illumination beam multiple times at intervals within one cycle.

[0102] By having the companion module 50 emit light intermittently within a cycle, a flashing light effect can be achieved, meeting the lighting display requirements and helping to improve the aesthetics of the vehicle 100 and enhance the user experience. Furthermore, eliminating the need for a separate optical module to achieve the flashing effect further reduces the number of optical modules required, thereby lowering the cost of the vehicle lighting device 110.

[0103] In some possible implementations, the companion module 50 may also include a high beam assist mode. When the companion module 50 is in high beam assist mode, a second illumination light is used to achieve high beam assist lighting, which can enhance high beam lighting and help to further improve driving safety.

[0104] Specifically, during the high beam illumination process of the lighting module 30, the companion module 50 emits light, which can achieve high beam enhancement illumination.

[0105] In summary, in addition to low beam assist mode, second high beam mode, flashing mode, high beam assist mode and blind spot fill mode, the companion module 50 may also include other working modes, which will not be described in detail here.

[0106] Furthermore, when the companion module 50 has multiple operating modes, by controlling the companion module 50 to be in different operating modes, the companion module 50 can cooperate with the projection module 40 and / or the lighting module 30 to achieve different scenarios. For example, when the vehicle lighting device 110 is in the third mode, the companion module 50 and the lighting module 30 cooperate to achieve scenarios such as intelligent low beam and intelligent supplemental lighting. It can be seen that by enabling the companion module 50 to have multiple operating modes, the number of optical modules in the vehicle lighting device 110 can be reduced, which can reduce the size of the vehicle lighting device 110 and reduce its cost.

[0107] In some possible implementations, in addition to its projection function, the projection module 40 can also be used for auxiliary lighting. That is, the projection module 40 can include both a projection mode and a lighting mode. When in projection mode, the projection module 40 emits an imaging beam and forms an image in front of the vehicle body 120. When in lighting mode, the projection module 40 emits a third lighting beam, which is used to provide auxiliary lighting such as low beam auxiliary lighting, high beam auxiliary lighting, or blind spot lighting, further improving the range or brightness of the lighting and enhancing the overall lighting effect of the intelligent lighting system.

[0108] It should be noted that when the projection module 40 is in illumination mode, the projection module 40 can emit light simultaneously with the companion module 50 and / or the illumination module 30 to achieve different scenarios. For example, the projection module 40 and the companion module 50 emit light simultaneously, and the second illumination beam and the third illumination beam cooperate with each other to achieve adaptive illumination function.

[0109] Figure 5 is a schematic diagram of one control architecture of the vehicle lighting device in an embodiment of this application, and Figure 6 is a schematic diagram of another control architecture of the vehicle lighting device in an embodiment of this application.

[0110] In some possible implementations, the vehicle lighting device 110 may further include a controller 70, which is electrically connected to the projection module 40 and the companion module 50, respectively. The controller 70 is used to control the projection module 40 to emit an imaging beam, and / or, the controller 70 is used to control the companion module 50 to emit a second illumination beam.

[0111] It should be noted that, in addition to being part of the vehicle lighting device 110, in some embodiments, the vehicle 100 may also include the controller 70. In this case, the controller 70 and the vehicle lighting device 110 are two independent modules.

[0112] In some embodiments, the controller 70 may be used to control the projection module 40 to emit an imaging beam according to the sensing information output by the sensing module 60, and / or the controller 70 may be used to control the companion module 50 to emit a second illumination beam according to the sensing information output by the sensing module 60.

[0113] In this way, the controller 70 can control the projection module 40 and / or the companion module 50 to emit light based on the sensing information, so that the advantages of the projection module 40 and the companion module 50 complement each other, and meet the functional requirements of smart vehicle lights in multiple scenarios with the fewest number of modules.

[0114] The perception module 60 can be an advanced driver assistance system (ADAS), lidar, microwave radar, camera, etc. Perception information can be understood as the target coordinate information output by the perception module 60 based on the vehicle's surrounding environment.

[0115] For example, as shown in FIG5, there is one controller 70. The first end of the controller 70 is electrically connected to the sensing module 60, the second end of the controller 70 is electrically connected to the projection module 40, and the third end of the controller 70 is electrically connected to the companion module 50. The projection module 40 and the companion module 50 share the same controller 70.

[0116] In some embodiments, the controller 70 may be located inside the first headlight 10. In other embodiments, the controller 70 may also be located inside the second headlight 20.

[0117] Of course, besides sharing the same controller 70, in some embodiments, as shown in FIG6, the vehicle lighting device 110 may also include two controllers 70. One controller 70 has its first terminal electrically connected to the first terminal of the sensing module 60, and its second terminal electrically connected to the projection module 40. This controller 70 is used to control the projection module 40 to emit an imaging beam based on the sensing information output by the sensing module 60. The other controller 70 has its first terminal electrically connected to the second terminal of the sensing module 60, and its second terminal electrically connected to the companion module 50. This controller 70 is used to control the companion module 50 to emit a second illumination beam based on the sensing information output by the sensing module 60. In this way, while controlling the projection module 40 and the companion module 50, the performance of the controller 70 can be reduced, thereby reducing the cost of the controller 70 and consequently reducing the cost of the vehicle lighting device 110.

[0118] Figure 7 is a schematic diagram of the architecture of the second type of vehicle lighting device provided in the embodiments of this application.

[0119] In some embodiments, as shown in FIG7, one controller 70 may be disposed inside the first vehicle light 10, and the other controller 70 may be disposed inside the second vehicle light 20. In other embodiments, both controllers 70 may be disposed inside the first vehicle light 10, or both controllers 70 may be disposed inside the second vehicle light 20.

[0120] In some embodiments, the vehicle 100 includes a sensing module 60, in which case the sensing module 60 and the headlight device 110 are two independent modules, that is, the sensing module 60 is disposed outside the headlight device 110. However, in other embodiments, the sensing module 60 may also be integrated into the headlight device 110. Specifically, at least one of the first headlight 10 and the second headlight 20 may also include the sensing module 60.

[0121] In some implementations, as shown in FIG7, the first vehicle light 10 may include a sensing module 60. In other implementations, the second vehicle light 20 may include a sensing module 60. In still other implementations, as shown in FIG8, both the first vehicle light 10 and the second vehicle light 20 may include a sensing module 60. FIG8 is a schematic diagram of the architecture of a third type of vehicle light device provided in an embodiment of this application.

[0122] In the above description, the projection module 40 itself does not have control functions; the controller 70 controls the projection module 40 to emit the imaging beam. However, the projection module 40 can also have control functions.

[0123] Figure 9 is a schematic diagram of the architecture of another projection module provided in an embodiment of this application.

[0124] The difference between Figure 9 and Figure 5 is that the projection module 40 may include a control unit 41, which is electrically connected to the controller 70. The control unit 41 and the controller 70 are used to control the projection module 40 to emit an imaging beam. In other words, the control unit 41 has some control functions, and the controller 70 has other control functions. This arrangement allows the projection module 40 to possess some control functions itself, further improving the integration of the projection module 40.

[0125] In some embodiments, the control unit 41 and the controller 70 can control the projection module 40 to emit a projection beam based on the sensing information output by the sensing module 60. The sensing module 60 can be electrically connected to the control unit 41 and the controller 70 respectively, or the sensing module 60 can be electrically connected to either the control unit 41 or the controller 70.

[0126] In other embodiments, the control unit 41 and the controller 70 may also control the projection module 40 to emit an imaging beam according to the control commands output by the vehicle's infotainment system 100.

[0127] It should be noted that, in addition to the controller 70 and control unit 41 jointly controlling the projection module 40 to emit the imaging beam, in some embodiments, the control unit 41 can also be electrically connected to the sensing module 60. The control unit 41 can also be used to control the projection module 40 to emit the imaging beam based on the sensing information output by the sensing module 60. That is, the projection module 40 itself has complete control functions and can control the projection module 40 to emit light based on the sensing information. In other embodiments, the control unit 41 can also control the projection module 40 to emit the imaging beam according to the control commands output by the vehicle's infotainment system 100.

[0128] In the above description, high beam illumination can be provided through the lighting module 30 and / or the companion module 50, meaning that the high beam function is integrated into the lighting module 30 and / or the companion module 50. However, a high beam module 80, independent of the lighting module 30 and the companion module 50, can also be provided in the vehicle lighting device 110, meaning that the lighting module 30 and the companion module 50 do not have high beam functionality.

[0129] Figure 10 is a schematic diagram of the architecture of the fourth type of vehicle lighting device provided in the embodiments of this application.

[0130] The difference between Figure 10 and Figure 3 is that the number of working modes of the companion module 50 is different. Both the first headlight 10 and the second headlight 20 also include a high beam module 80. The high beam module 80 in the first headlight 10 and the high beam module 80 in the second headlight 20 are arranged symmetrically. The high beam module 80 is used to realize high beam illumination, which can provide long-distance illumination in environments with poor visibility (such as dark environments or dim environments) and increase the driver's field of vision.

[0131] In some embodiments, when the high beam module 80 can be used to implement adaptive high beam lighting, it can automatically adjust the illumination range of the high beam module 80 according to the position and distance of oncoming vehicles, turning off or dimming the light illumination command in the area of ​​oncoming vehicles, thereby reducing glare for oncoming vehicles while maximizing the driver's visibility needs. In other embodiments, the high beam module 80 can also be used to implement non-adaptive high beam lighting, that is, the high beam module 80 is used to implement ordinary high beam lighting.

[0132] In some embodiments, when the companion module 50 has a high beam assist mode, the companion module 50 emits light during the high beam illumination process of the high beam module 80, which can achieve high beam enhancement illumination and help to further improve driving safety.
