The low beam module is used to realize the low beam function, and the high beam module is used to realize the high beam function. The two projection modules jointly emit a projection beam and realize the interactive / entertainment projection function. However, due to the high cost of the projection module and the number of projection modules is two, the cost of the lighting system is high. Utility Model Content

[0003] The embodiments of the present application provide a projection module, a vehicle lamp device and a vehicle, which can reduce the number of projection modules and reduce the cost of the vehicle lamp device.

[0004] In a first aspect, the present application provides a vehicle lamp device, comprising a first vehicle lamp and a second vehicle lamp, wherein the first vehicle lamp and the second vehicle lamp are arranged on the same vehicle. The first vehicle lamp comprises a lighting module and a projection module, and the second vehicle lamp comprises a lighting module and a companion module. The lighting module in the first vehicle lamp is symmetrically arranged with the lighting module in the second vehicle lamp, and the lighting module is used to emit a first lighting beam. The projection module is symmetrically arranged with the companion module, and the projection module is used to emit an imaging beam that forms an image, and the companion module is used to emit a second lighting beam.

[0005] The vehicle lamp device provided in the embodiment of the present application realizes the projection of icons, pictures, videos and other contents through a high-resolution projection module, realizes the interactive needs and projection needs, and improves driving safety. In addition, lighting can be realized by at least one of the lighting module, the projection module and the companion module to meet the lighting needs. In addition, when the lighting module realizes the lighting needs, the projection module and / or the companion module can be used to enhance the lighting, which can further improve driving safety.

[0006] Since there is only one projection module, the cost of the vehicle lighting device can be reduced while meeting the projection and interaction requirements. In addition, the companion module and the projection module cooperate with each other to meet the functional requirements of the vehicle lighting device in multiple scenarios.

[0007] In a possible implementation, the lighting module includes a low-beam mode. When the lighting module is in the low-beam mode, the first lighting light beam is used to achieve low-beam lighting.

[0008] In this way, the lighting needs can be met in environments with poor visibility (such as dark environments and dim environments), thereby improving driving safety.

[0009] In a possible implementation, the lighting module further includes a first high-beam mode. When the lighting module is in the first high-beam mode, the first lighting light beam is used to achieve high-beam lighting.

[0010] In this way, long-distance lighting can be provided in environments with poor visibility (such as dark environments and dim environments), thereby increasing the driving field of vision.

[0011] In a possible implementation, when the lighting module is in the first high-beam mode, the first lighting light beam is used to implement adaptive high-beam lighting.

[0012] In this way, the illumination range of the lighting module can be automatically adjusted according to the position and distance of the oncoming vehicle, and the lighting instructions in the oncoming vehicle area can be turned off or dimmed, thereby reducing the glare caused by the oncoming vehicle and maximizing the driver's vision needs.

[0013] In a possible implementation, the first headlight and the second headlight both further include a high beam module, the high beam module in the first headlight and the high beam module in the second headlight are symmetrically arranged, and the high beam module is used to realize high beam lighting.

[0014] In this way, long-distance lighting can be provided in environments with poor visibility (such as dark environments and dim environments), thereby increasing the driving field of vision.

[0015] In a possible implementation, the high beam module is used to implement adaptive high beam lighting.

[0016] In this way, the illumination range of the high beam module can be automatically adjusted according to the position and distance of the oncoming vehicle, and the lighting instructions in the oncoming vehicle area can be turned off or dimmed, thereby reducing the glare caused by the oncoming vehicle and maximizing the driver's vision needs.

[0017] In a possible implementation, the companion module further includes a second high-beam mode. When the companion module is in the second high-beam mode, the second lighting beam is used to achieve high-beam lighting.

[0018] In this way, long-distance lighting can be provided in environments with poor visibility (such as dark environments and dim environments), thereby increasing the driving field of vision.

[0019] In a possible implementation, when the companion module is in the second high-beam mode, the second lighting beam is used to implement adaptive high-beam lighting.

[0020] In this way, the illumination range of the companion module can be automatically adjusted according to the position and distance of the oncoming vehicle, and the lighting instructions in the oncoming vehicle area can be turned off or dimmed, thereby reducing the glare caused by the oncoming vehicle and maximizing the driver's vision needs.

[0021] In a possible implementation, the companion module includes a low-beam auxiliary mode, and when the companion module is in the low-beam auxiliary mode, the second lighting beam is used to implement low-beam auxiliary lighting.

[0022] In this way, when the lighting module realizes low beam lighting, the companion module emits light, which can realize low beam enhanced lighting and further improve driving safety.

[0023] In a possible implementation, the companion module includes a high-beam assist mode, and when the companion module is in the high-beam assist mode, the second lighting beam is used to implement high-beam assist lighting.

[0024] In this way, when the high beam module or the lighting module realizes high beam lighting, the companion module emits light, which can realize high beam enhanced lighting, helping to further improve driving safety.

[0025] In a possible implementation, the companion module includes a flashing mode. When the companion module is in the flashing mode, the companion module emits a plurality of second illumination light beams at intervals within a cycle.

[0026] In this way, the companion module emits light at intervals within a cycle, which can warn the target to improve the safety of the driver and people outside the vehicle, and can also be used to improve the aesthetics of the vehicle. At the same time, there is no need to increase the number of modules of the vehicle lighting device, which helps to reduce the cost of the vehicle lighting device.

[0027] In a possible implementation, the companion module includes a blind spot fill light mode. When the companion module is in the blind spot fill light mode, the second illumination light beam is used to realize blind spot illumination.

[0028] In this way, without increasing the number of modules in the vehicle lamp device, driving safety can be further improved and the cost of the vehicle lamp device can be reduced.

[0029] In a possible implementation, the vehicle lamp device further includes a controller, which is electrically connected to the projection module and the companion module, respectively. 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.

[0030] In a possible implementation, the vehicle lamp device further includes a controller, which is electrically connected to the projection module and the companion module, respectively. The controller is used to control the projection module to emit an imaging beam according to the perception information output by the perception module, and / or the controller is used to control the companion module to emit a second illumination beam according to the perception information output by the perception module.

[0031] In this way, the controller can control the projection module and / or companion module to emit light according to the perception information, so that the advantages of the projection module and the companion module complement each other, and meet the functional requirements of smart car lights in multiple scenarios with a minimum number of modules.

[0032] In a possible implementation manner, at least one of the first headlight and the second headlight further includes a sensing module, and the sensing module is electrically connected to the controller.

[0033] In a possible implementation, the vehicle lighting device includes two controllers, one of which is used to control the projection module to emit an imaging beam according to the perception information output by the perception module, and the other controller is used to control the companion module to emit a second lighting beam according to the perception information output by the perception module.

[0034] In this way, on the basis of realizing 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 further reducing the cost of the vehicle lamp device.

[0035] In a possible implementation, the projection module includes a projection mode and an illumination mode. When the projection module is in the projection mode, the projection module emits an imaging beam. When the projection module is in the illumination mode, the projection module emits a third illumination beam, and the third illumination beam is used to achieve auxiliary illumination.

[0036] In this way, in addition to realizing the projection function, the projection module can also perform auxiliary lighting such as low beam auxiliary lighting, high beam auxiliary lighting or blind spot lighting in the lighting scene, thereby further improving the lighting range or brightness, and further improving the lighting effect of intelligent lighting.

[0037] In a possible implementation, the vehicle light device includes a first mode, a second mode, a third mode, a fourth mode, a fifth mode, a sixth mode and a seventh mode. When the vehicle light device is in the first mode, the projection module emits an imaging beam. When the vehicle light device is in the second mode, the lighting module emits a first lighting beam. When the vehicle light device is in the third mode, the companion module emits a second lighting beam. When the vehicle light device is in the fourth mode, the projection module emits an imaging beam, and the lighting module emits a first lighting beam. When the vehicle light device is in the fifth mode, the lighting module emits a first lighting beam, and the companion module emits a second lighting beam. When the vehicle light device is in the sixth mode, the projection module emits an imaging beam, the lighting module emits a first lighting beam, and the companion module emits a second lighting beam. When the vehicle light device is in the seventh mode, the projection module emits an imaging beam, and the companion module emits a second lighting beam.

[0038] In this way, through the cooperation of the light emitted by the projection module, lighting module and companion module, the three major functional scenarios of intelligent lighting, intelligent interaction and intelligent projection can be realized with a minimum number of modules. On the one hand, it can improve driving safety, and on the other hand, it can improve the user experience.

[0039] The second aspect of the present application provides a projection module, which is arranged in a first headlight. The first headlight also includes a lighting module. The lighting module in the first headlight is symmetrically arranged with the lighting module in the second headlight, and the lighting module is used to emit a first lighting beam. The first headlight and the second headlight are arranged on the same vehicle. The second 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 lighting beam.

[0040] In a possible implementation, the projection module includes a projection mode and an illumination mode. When the projection module is in the projection mode, the projection module emits an imaging beam. When the projection module is in the illumination mode, the projection module emits a third illumination beam, and the third illumination beam is used to achieve auxiliary illumination.

[0041] In this way, in addition to realizing the projection function, the projection module can also perform auxiliary lighting such as low beam auxiliary lighting, high beam auxiliary lighting or blind spot lighting in the lighting scene, thereby further improving the lighting range or brightness, and further improving the lighting effect of intelligent lighting.

[0042] In a possible implementation, the projection module includes a control unit, the control unit is used to be electrically connected to the controller, and the control unit and the controller are used to control the projection module to emit an imaging light beam.

[0043] In this way, by setting a control unit in the projection module, the control function is transferred to the projection module, and the projection module itself has some control functions, which cooperate with the control functions deployed on other controllers to control the projection module.

[0044] In a possible implementation, the projection module includes a control unit, and the control unit is used to control the projection module to emit an imaging light beam according to the perception information.

[0045] In this way, the projection module itself has a control function, which can control the projection module to emit an imaging beam according to the perception information.

[0046] In a possible implementation, the lighting module includes a low-beam mode. When the lighting module is in the low-beam mode, the first lighting light beam is used to achieve low-beam lighting.

[0047] In a possible implementation, the lighting module further includes a first high-beam mode. When the lighting module is in the first high-beam mode, the first lighting light beam is used to achieve high-beam lighting.

[0048] In a possible implementation, the companion module further includes a second high-beam mode. When the companion module is in the second high-beam mode, the second lighting beam is used to achieve high-beam lighting.

[0049] In a possible implementation, the companion module includes a low-beam auxiliary mode, and when the companion module is in the low-beam auxiliary mode, the second lighting beam is used to implement low-beam auxiliary lighting.

[0050] In a possible implementation, the companion module includes a high-beam assist mode, and when the companion module is in the high-beam assist mode, the second lighting beam is used to implement high-beam assist lighting.

[0076] Figure 1FIG. 1 is a schematic diagram of the architecture of a vehicle light system in the related art. Figure 1 As shown, the vehicle lighting system includes a left headlight 200 and a right headlight 300. The left headlight 200 is installed at the left front of the vehicle, and the right headlight 300 is installed at the right front of the vehicle. Both the left headlight 200 and the right headlight 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, the two high beam modules 203 are symmetrically arranged, and the two low beam modules 202 are symmetrically arranged. The two low beam modules 202 are used to realize the low beam function and realize low beam lighting. Both projection modules 201 are high-resolution DLP modules, which have the characteristics of high resolution and high definition. The two projection modules 201 emit projection beams together and overlap each other to realize interactive or entertainment projection functions.

[0077] However, the cost of the projection module 201 is high, and there are two projection modules 201, which makes the cost of the vehicle lamp device high. In addition, the number of modules in the vehicle lamp device is also large, which also leads to the high cost of the vehicle lamp device. Therefore, how to meet the needs of multiple scenarios while reducing the cost of the vehicle lamp device has become an urgent problem to be solved.

[0078] In view of this, the embodiment of the present application provides a projection module 40, a vehicle light device 110 and a vehicle 100, which meet the needs of multiple scenarios with a smaller number of modules. At the same time, the number of projection modules 40 is one, which can reduce the cost of the vehicle light device 110.

[0079] The vehicle 100 may be a car, a truck, a motorcycle, a bus, an amusement vehicle, an amusement park vehicle, construction equipment, a tram, etc. In the embodiment of the present application, the vehicle 100 is taken as a car as an example for description.

[0080] Figure 2 A schematic diagram of the structure of a vehicle provided in an embodiment of the present application.

[0081] like Figure 2 As shown, the vehicle 100 includes a vehicle body 120 and a headlight device 110. The headlight device 110 is installed on the vehicle body 120. The headlight device 110 can realize three 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.

[0082] Among them, intelligent lighting can include intelligent low beam and intelligent high beam. Intelligent low beam can include low beam enhanced lighting, and intelligent high beam can include high beam enhanced lighting and adaptive driving beam (ADB) and other scenes.

[0083] Intelligent interaction can include driving guidance, driving prompts and interaction. Driving guidance can be 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. Driving interaction can include scenarios such as driving trajectory interaction and zebra crossing information.

[0084] Smart projection can include ground projection and wall projection, and can realize scenarios such as mobile phone multimedia, car multimedia, PC multimedia, interactive games and welcoming guests.

[0085] For example, Figure 2 As shown, the vehicle lamp device 110 may be a front lamp module, which is installed in front of the vehicle body 120. In some implementations, the vehicle lamp device 110 may also be a rear lamp module, which is installed at the rear of the vehicle body 120. In other implementations, the vehicle lamp device 110 may also be a side lamp module, which is installed on the left or right side of the vehicle body 120.

[0086] like Figure 2 As shown, the headlight device 110 includes a first headlight 10 and a second headlight 20, and the first headlight 10 and the second headlight 20 are arranged on the body 120 of the same vehicle 100. The first headlight 10 is installed at the left front of the body 120, and the second headlight 20 is installed at the right front of the body 120. The first headlight 10 and the second headlight 20 are arranged symmetrically. Therefore, the first headlight 10 can be similar to the left headlight in function, and the second headlight 20 can be similar to the right headlight in function. The first headlight 10 and the second headlight 20 have at least a low beam function and a high beam function in function, and can realize low beam lighting and high beam lighting, meeting the requirements of driving safety.

[0087] Figure 3 This is a schematic diagram of the architecture of a first vehicle lamp device provided in an embodiment of the present application. Figure 4 for Figure 3 Schematic diagram of the light emission of each module in the vehicle lighting device.

[0088] like Figure 3 As shown, the first headlight 10 includes a lighting module 30 and a projection module 40, and the second headlight 20 includes a lighting module 30 and a companion module 50. The lighting module 30 in the first headlight 10 is symmetrically arranged with the lighting module 30 in the second headlight 20, and the lighting module 30 is used to emit a first lighting beam (such as Figure 4 The projection module 40 and the companion module 50 are symmetrically arranged, so that the layout of the internal modules of the first headlight 10 and the second headlight 20 is symmetrical, which can improve the aesthetics of the vehicle 100. The projection module 40 is used to emit an imaging beam (such as Figure 4As shown in B), the image formed by the imaging beam can be information such as text, pictures, video content, etc., to achieve projection requirements. The companion module 50 is used to emit a second illumination beam.

[0089] 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 positioned parallel to the center line of the length direction of the vehicle 100 (eg Figure 3 The two ends are symmetrical (shown by X in the figure).

[0090] During the operation of the projection module 40, the imaging beam emitted by the projection module 40 hits the front of the vehicle 100, so that the image formed by the imaging beam is projected onto the ground and into the air. Among them, the image projected into the front air is mainly the high beam intensity distribution information, and the image projected onto the ground may include the low beam intensity distribution information and any one or more of the custom patterns (for example, zebra crossings, arrows, triangles, manufacturer logos, texts, etc., which serve as prompts, welcoming or interactive patterns). It should be understood that the imaging beam emitted by the projection module 40 can be projected onto walls and other places in addition to being projected onto the ground.

[0091] In the embodiment of the present application, the projection module 40 adopts a pixelated imaging device, such as a MEMS, DMD, LCOS, LCD or MicroLED imaging device, so that the resolution of the projection module 40 is high and the projection function can be realized.

[0092] The companion module 50 may also be a pixelated light module, in which case the pixels of the companion module 50 are lower than those of the projection module 40, that is, the resolution of the companion module 50 is lower than that of the projection module 40. For example, the projection module 40 may be a module of megapixel level, and the companion module 50 may be a module of kilopixel or lower pixels.

[0093] In summary, the projection module 40 has a high resolution, so that the projection module 40 has a high-definition characteristic, and can project icons, pictures or video content, etc., for realizing intelligent interaction and intelligent projection. The companion module 50 has a low resolution, and can have the characteristics of a large field of view and high brightness. It can supplement the lighting radiation range and lighting brightness in the lighting scene, or perform high beam lighting to realize intelligent lighting. Therefore, the projection module 40 and the companion module 50 are arranged symmetrically, and the light types are complementary, so that the performance of the vehicle light device 110 meets the lighting and projection performance requirements. In addition, the number of projection modules 40 is one, and the number of modules in the vehicle light device 110 is reduced, which can reduce the cost of the vehicle light device 110.

[0094] like Figure 3As shown, the first vehicle lamp 10 may further include a first housing 11, and a projection module 40 and one of the lighting modules 30 are disposed inside the first housing 11. The second vehicle lamp 20 may further include a second housing 21, and another lighting module 30 and a companion module 50 are disposed inside the second housing 21.

[0095] Exemplarily, the vehicle lamp 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. Among them, when the vehicle lamp device 110 is in the first mode, the projection module 40 emits an imaging beam. When the vehicle lamp device 110 is in the second mode, the lighting module 30 emits a first lighting beam. When the vehicle lamp device 110 is in the third mode, the companion module 50 emits a second lighting beam. When the vehicle lamp device 110 is in the fourth mode, the projection module 40 emits an imaging beam, and the lighting module 30 emits a first lighting beam. When the vehicle lamp device 110 is in the fifth mode, the lighting module 30 emits a first lighting beam, and the companion module 50 emits a second lighting beam. When the vehicle lamp device 110 is in the sixth mode, the projection module 40 emits an imaging beam, the lighting module 30 emits a first lighting beam, and the companion module 50 emits a second lighting beam. When the vehicle lamp device 110 is in the seventh mode, the projection module 40 emits an imaging beam, and the companion module 50 emits a second lighting beam

[0096] By controlling at least one of the projection module 40, the companion module 50 and the lighting module 30 in the vehicle lamp device 110 to emit light, the vehicle lamp device 110 has multiple working modes. The vehicle lamp device 110 can realize three functional scenarios of intelligent lighting, intelligent interaction and intelligent projection with the least number of modules, which can improve driving safety on the one hand and improve user experience on the other hand. At the same time, the small number of modules in the vehicle lamp device 110 can reduce the cost of the vehicle lamp device 110.

[0097] It is understandable that at the same time, one of the illumination module 30, projection module 40 and companion module 50 may emit light. Alternatively, two of the illumination module 30, projection module 40 and companion module 50 may emit light. Alternatively, all of the illumination module 30, projection module 40 and companion module 50 may emit light.

[0098] It should be noted that the number of working modes of the vehicle light device may also be part of the first mode to the seventh mode, which will not be described one by one here.

[0099] For example, Figure 2As shown, 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 modules 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 achieve low beam lighting, so that the first headlight 10 and the second headlight 20 have a low beam function, which can provide lighting needs in environments with poor visibility (such as night environments and dim environments), thereby improving driving safety.

[0100] It should be noted that in addition to the low beam mode, in some possible implementations, the lighting module 30 may also include a first high beam mode. When the lighting module 30 is in the first high beam mode, the lighting module 30 is functionally similar to the high beam module 80. At this time, the first lighting beam is used to achieve high beam lighting, which can provide long-distance lighting in environments with poor visibility (such as night environments and dim environments) to increase driving vision.

[0101] In some embodiments, when the lighting module 30 is in the first high beam mode, the first lighting beam can be used to implement adaptive high beam lighting, and the lighting range of the lighting module 30 can be automatically adjusted according to the position and distance of the opposite vehicle, and the lighting instructions of the opposite vehicle area can be turned off or dimmed, thereby reducing the glare of the opposite vehicle and maximally satisfying the driver's vision requirements. In other embodiments, when the lighting module 30 is in the first high beam mode, the first lighting beam can also be used to implement non-adaptive high beam lighting, which can also be understood as the first lighting beam being used to implement ordinary high beam lighting.

[0102] It should also be noted that in addition to being used as a low beam module or a high beam module 80, the lighting module 30 can also be used as other types of lighting modules. For example, when the vehicle lamp device 110 is installed at the rear of the vehicle body 120, the first vehicle lamp 10 can also be a left rear lamp, and the second vehicle lamp 20 can also be a right rear lamp. At this time, the lighting module 30 can be functionally similar to a brake light module. When braking, the lighting module 30 emits a first lighting beam to prompt the vehicle behind to slow down.

[0103] In some possible implementations, the companion module 50 may include a low beam auxiliary mode. When the companion module 50 is in the low beam auxiliary mode, the second lighting beam is used to implement low beam auxiliary lighting (eg Figure 4 (as shown in C).

[0104] Exemplarily, when the vehicle lamp device 110 is in the fifth mode, during the low beam lighting process of the lighting module 30, the second lighting beam cooperates with the first lighting beam to increase the range and / or brightness of the low beam lighting and achieve low beam enhanced lighting.

[0105] 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, the companion module 50 is functionally similar to a high beam module 80. At this time, the second lighting beam is used to implement high beam lighting, which can provide long-distance lighting in environments with poor visibility (such as night environments, dim environments), thereby increasing the driving field of vision.

[0106] In some embodiments, when the companion module 50 is in the second high beam mode, the second lighting beam can be used to implement adaptive high beam lighting (eg Figure 4 D in the figure), the illumination range of the companion module 50 can be automatically adjusted according to the position and distance of the opposite vehicle, and the lighting instructions of the opposite vehicle area can be turned off or dimmed, thereby reducing the glare of the opposite vehicle and maximally satisfying the driver's vision requirements. In other embodiments, when the companion module 50 is in the second high beam mode, the second lighting beam can also be used to achieve non-adaptive high beam lighting, which can also be understood as the first lighting beam being used to achieve ordinary high beam lighting.

[0107] It should be noted that one of the lighting module 30 and the companion module 50 has a high beam mode, and the other does not have a high beam mode. For example, when the lighting module 30 has a first high beam mode, the companion module 50 does not have a second high beam mode. Alternatively, when the lighting module 30 has a first high beam mode, the companion module 50 may also have a second high beam mode. In this case, one of the first lighting beam and the second lighting beam is used to implement non-adaptive high beam lighting, and the other is used to implement adaptive high beam lighting.

[0108] In some possible implementations, the companion module 50 may also include a blind spot fill light mode. When the companion module 50 is in the blind spot fill light mode, the second illumination light beam is used to realize blind spot illumination.

[0109] Exemplarily, when the vehicle lamp device 110 is in the fifth mode, during the low beam lighting process of the lighting module 30, the second lighting beam illuminates the range that is not illuminated by the first lighting beam, which can further improve the driver's field of vision and help to further improve driving safety.

[0110] In some possible implementations, the companion module 50 may further include a flashing mode. When the companion module 50 is in the flashing mode, the companion module 50 emits a plurality of second illumination light beams at intervals within a cycle.

[0111] By emitting light at intervals in a cycle, the companion module 50 can achieve a flashing effect, meet the requirements of light display, help improve the aesthetics of the vehicle 100, and improve the user experience. In addition, there is no need to set up an independent optical module to achieve the flashing requirement, which can further reduce the number of optical modules and further reduce the cost of the vehicle lamp device 110.

[0112] In some possible implementations, the companion module 50 may also include a high beam assist mode. When the companion module 50 is in the high beam assist mode, the second lighting light is used to implement high beam assist lighting, which can achieve high beam enhanced lighting and help to further improve driving safety.

[0113] Specifically, when the lighting module 30 performs high-beam lighting, the companion module 50 emits light to achieve high-beam enhanced lighting.

[0114] In summary, the companion module 50 may include other working modes in addition to the low beam assist mode, the second high beam mode, the flashing mode, the high beam assist mode and the blind spot fill light mode, which will not be described one by one here.

[0115] In addition, when the companion module 50 has multiple working modes, by controlling the companion module 50 to be in different working modes, the companion module 50 can cooperate with the projection module 40 and / or the lighting module 30 to realize different scenes. For example, when the vehicle lamp device 110 is in the third mode, the companion module 50 and the lighting module 30 cooperate with each other to realize scenes such as intelligent low beam and intelligent fill light. It can be seen that by allowing the companion module 50 to have multiple working modes, the number of optical modules in the vehicle lamp device 110 can be reduced, which can reduce the size of the vehicle lamp device 110 on the one hand and reduce the cost of the vehicle lamp device 110 on the other hand.

[0116] In some possible implementations, in addition to being used to realize the projection function, the projection module 40 can also be used to realize auxiliary lighting. That is, the projection module 40 can also include a projection mode and a lighting mode. Among them, when the projection module 40 is in the projection mode, the projection module 40 emits an imaging beam and forms an image in front of the vehicle body 120. When the projection module 40 is in the lighting mode, the projection module 40 emits a third lighting beam, and the third lighting beam is used to realize auxiliary lighting such as low beam auxiliary lighting, high beam auxiliary lighting or blind spot lighting, which can further improve the range or brightness of the lighting, and can further improve the lighting effect of the intelligent lighting.

[0117] It should be noted that when the projection module 40 is in the lighting mode, the projection module 40 can emit light simultaneously with the companion module 50 and / or the lighting module 30 to achieve different scenes. Exemplarily, the projection module 40 and the companion module 50 emit light simultaneously, and the second lighting beam and the third lighting beam cooperate with each other to achieve the adaptive lighting function.

[0118] Figure 5 is a schematic diagram of a control architecture of a vehicle light device in an embodiment of the present application, Figure 6 Schematic diagram of another control structure of the vehicle light device in the embodiment of the present application.

[0119] In some possible implementations, the vehicle lamp device 110 may further include a controller 70, which is electrically connected to the projection module 40 and the companion module 50. 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.

[0120] It should be noted that, in addition to belonging to the vehicle light device 110 , in some embodiments, the vehicle 100 may also include the controller 70 . In this case, the controller 70 and the vehicle light device 110 are two independent modules.

[0121] In some embodiments, the controller 70 can be used to control the projection module 40 to emit an imaging beam according to the perception information output by the perception module 60, and / or the controller 70 can be used to control the companion module 50 to emit a second illumination beam according to the perception information output by the perception module 60.

[0122] In this way, the controller 70 can control the projection module 40 and / or the companion module 50 to emit light according to the perception 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 car lights in multiple scenarios with a minimum number of modules.

[0123] The sensing module 60 may be an advanced driver assistance system (ADAS), a laser radar, a microwave radar, a camera, etc. The sensing information may be understood as target coordinate information that the sensing module 60 may output based on the vehicle's surrounding environment.

[0124] For example, Figure 5 As shown, there is one controller 70, a first end of the controller 70 is electrically connected to the sensing module 60, a second end of the controller 70 is electrically connected to the projection module 40, a third end of the controller 70 is electrically connected to the companion module 50, and the projection module 40 and the companion module 50 share the same controller 70.

[0125] In some embodiments, the controller 70 may be disposed inside the first vehicle lamp 10 . In other embodiments, the controller 70 may also be disposed inside the second vehicle lamp 20 .

[0126] Of course, in addition to sharing the same controller 70, the projection module 40 and the companion module 50 may also be configured to be connected to the same controller 70 in some embodiments, such as Figure 6 As shown, the vehicle lamp device 110 may also include two controllers 70. Among them, the first end of one of the controllers 70 is electrically connected to the first end of the sensing module 60, the second end of one of the controllers 70 is electrically connected to the projection module 40, and one of the controllers 70 is used to control the projection module 40 to emit an imaging light beam according to the sensing information output by the sensing module 60. The first end of the other controller 70 is electrically connected to the second end of the sensing module 60, the second end of the other controller 70 is electrically connected to the companion module 50, and the other controller 70 is used to control the companion module 50 to emit a second illumination light beam according to the sensing information output by the sensing module 60. In this way, on the basis of realizing the control of 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 further reducing the cost of the vehicle lamp device 110.

[0127] Figure 7 This is a schematic diagram of the architecture of a second vehicle lamp device provided in an embodiment of the present application.

[0128] In some embodiments, Figure 7 As shown, one controller 70 can be disposed inside the first headlight 10, and the other controller 70 can be disposed inside the second headlight 20. In other embodiments, both controllers 70 can also be disposed inside the first headlight 10, or both controllers 70 can be disposed inside the second headlight 20.

[0129] In some embodiments, the vehicle 100 includes a sensing module 60. In this 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.

[0130] In some implementations, such as Figure 7 As shown, the first vehicle lamp 10 may include a sensing module 60. In other implementations, the second vehicle lamp 20 may include a sensing module 60. In still other implementations, Figure 8 As shown, the first headlight 10 and the second headlight 20 may both include a sensing module 60. Figure 8 This is a schematic diagram of the architecture of a third vehicle lamp device provided in an embodiment of the present application.

[0131] In the above content, the projection module 40 itself does not have a control function, and the projection module 40 is controlled by the controller 70 to emit an imaging light beam. However, the projection module 40 may also have a control function.

[0132] Fig. 9 A schematic diagram of the architecture of another projection module provided in an embodiment of the present application.

[0133] Fig. 9 and Figure 5 The difference is that the projection module 40 may include a control unit 41, the control unit 41 is used to be electrically connected to the controller 70, and the control unit 41 and the controller 70 are used to control the projection module 40 to emit an imaging light beam, that is, the control unit 41 has a part of the control function, and the controller 70 has another part of the control function. In this way, the projection module 40 itself has part of the control function, which can further improve the integration of the projection module 40.

[0134] In some embodiments, the control unit 41 and the controller 70 can control the projection module 40 to emit a projection beam according to 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 the control unit 41 or the controller 70.

[0135] In other embodiments, the control unit 41 and the controller 70 may also control the projection module 40 to emit an imaging light beam according to a control instruction output by a vehicle computer of the vehicle 100 .

[0136] It should be noted that, in addition to controlling the projection module 40 to emit an imaging light beam by the controller 70 and the control unit 41, in some embodiments, the control unit 41 may also be electrically connected to the sensing module 60, and the control unit 41 may also be used to control the projection module 40 to emit an imaging light beam according to the sensing information output by the sensing module 60. In other words, the projection module 40 itself has a complete control function and can control the projection module 40 to emit light according to the sensing information. In other embodiments, the control unit 41 may also control the projection module 40 to emit an imaging light beam according to the control instructions output by the vehicle computer of the vehicle 100.

[0137] In the above content, high beam lighting can be performed by the lighting module 30 and / or the companion module 50, that is, 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 lamp device 110, that is, the lighting module 30 and the companion module 50 do not have the high beam function.

[0138] Fig.10This is a schematic diagram of the architecture of a fourth vehicle lamp device provided in an embodiment of the present application.

[0139] Fig.10 and Figure 3 The difference is that the number of working modes of the companion module 50 is different, and the first headlight 10 and the second headlight 20 both further 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 symmetrically arranged, and the high beam module 80 is used to realize high beam lighting, which can provide long-distance lighting in an environment with poor vision (such as a dark environment or a dim environment) to increase the driving vision.

[0140] In some embodiments, when the high beam module 80 can be used to implement adaptive high beam lighting, the illumination range of the high beam module 80 can be automatically adjusted according to the position and distance of the opposite vehicle, and the lighting instructions of the opposite vehicle area can be turned off or dimmed, thereby reducing the glare of the opposite vehicle and maximally meeting the driver's vision requirements. 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.

[0141] In some embodiments, when the companion module 50 has a high beam assist mode, during the process of the high beam module 80 performing high beam lighting, the companion module 50 emits light, which can achieve high beam enhanced lighting, helping to further improve driving safety.
