Description

Technical Field

[0001] The present application relates to the technical field of vehicles, and specifically relates to a headlight system, a headlight, and a vehicle. Background Art

[0002] When driving at night, in order to improve the lighting effect, it is usually necessary to turn on the high beam. However, the high beam will cause glare to the drivers of oncoming or same-side vehicles, etc., which is likely to trigger accidental accidents and pose potential safety hazards. In order to balance the purposes of high beam lighting and anti-glare, an Adaptive Driving Beam (ADB) system has emerged as the times require.

[0003] The ADB system is an intelligent anti-glare high beam system. It can sense other vehicles existing in front of the vehicle through a camera, and calculate and control the corresponding light emitting diode (LED) particles in the high beam group to dim or go out in real time, so as to form a dark area in the road surface area where other vehicles are located and avoid causing a glare effect on the vehicle ahead. However, currently, the dark area formed by the ADB system is relatively large, which affects the lighting of the road surface in front of the vehicle and is prone to breeding safety accidents. Summary of the Invention

[0004] The present application provides a headlight system, a headlight, and a vehicle, which can reduce the dark area of high beam occlusion, prevent glare and at the same time illuminate the road surface in front of the vehicle itself, greatly improving driving safety.

[0005] In a first aspect, the present application provides a headlight system, and the headlight system includes a headlight and a headlight controller;

[0006] The headlight includes a first light emitting module and a second light emitting module; the first light emitting module and the second light emitting module are pixelated light emitting modules, and the pixels of the first light emitting module are higher than those of the second light emitting module;

[0007] The headlight controller is used to control the first light emitting module and the second light emitting module to emit light;

[0008] The pattern formed by the second light emitting module emitting light includes a first area and a second area. The first area is the area covered by the light of the second light emitting module, and the second area is the area not covered by the light of the second light emitting module;

[0009] The second area includes a target object, and the area between the target object and the headlight in the second area belongs to a third area, and the light of the first light emitting module covers the third area.

[0010] Optionally, the foregoing first light-emitting module is a light-emitting module implemented based on digital light processing (DLP); the foregoing second light-emitting module is a light-emitting module implemented based on multiple light-emitting diodes (LEDs).

[0011] In the above solution, through the cooperation of the high-pixel light-emitting module (the foregoing first light-emitting module) and the low-pixel light-emitting module (the foregoing second light-emitting module), the far-light shielding dark area formed by the low-pixel light-emitting module is reduced, and high-precision far-light shielding in front of the vehicle (for example, the main visual area of the driver) is achieved. It not only prevents dazzling of oncoming or oncoming target objects in front of the vehicle but also illuminates the road surface in front of the vehicle, greatly improving driving safety.

[0012] In a possible implementation, the maximum illumination range of the foregoing second light-emitting module is greater than the maximum illumination range of the foregoing first light-emitting module.

[0013] In the above solution, the illumination coverage range of the high-pixel first light-emitting module is small. Therefore, in this solution, the low-pixel second light-emitting module can also be used to expand the illumination coverage range. While expanding the illumination range, the far-light shielding coverage angle can also be expanded, with more application scenarios and more shielding objects.

[0014] In a possible implementation, the foregoing vehicle lamp controller is used to control the foregoing first light-emitting module and the foregoing second light-emitting module to emit light, including:

[0016] The foregoing vehicle lamp controller is further used to control the foregoing first light-emitting module to emit light based on the foregoing first pixel coordinate and control the foregoing second light-emitting module to emit light based on the foregoing second pixel coordinate.

[0017] In the above solution, the position of the far-light shielding dark area can be accurately located through the position information of the target object, so that the illumination coverage area of the light-emitting module can be accurately controlled, and accurate far-light shielding can be achieved.

[0018] In a possible implementation, the foregoing vehicle lamp controller is used to receive the position information of the foregoing target object and determine a first pixel coordinate and a second pixel coordinate based on the foregoing position information, including:

[0019] The aforementioned headlight controller is used to receive the aforementioned position information and the type information of the aforementioned target object, and when the aforementioned type information indicates that the aforementioned target object belongs to a preset type of high-beam shielding object, determine a first pixel coordinate and a second pixel coordinate based on the aforementioned position information.

[0020] In the above solution, the type of the high-beam shielding object is preset, and only the object that meets the preset type is subjected to high-beam shielding, so that unnecessary shielding operations can be reduced, saving computing resources and reducing interference with road lighting at the same time.

[0021] In a possible implementation manner, the aforementioned headlight controller includes a first controller and a second controller. The aforementioned first controller is used to control the aforementioned first light-emitting module to emit light, and the aforementioned second controller is used to control the aforementioned second light-emitting module to emit light.

[0023] In a possible implementation manner, the aforementioned headlight system further includes a sensing device, and the aforementioned sensing device is used to sense the position and / or type of the aforementioned target object.

[0024] In the above solution, the position information and / or type information of the target object can be accurately obtained through the sensing device, so as to achieve accurate high-beam shielding.

[0025] In a possible implementation manner, the aforementioned third region further includes the regions on both sides of the aforementioned target object within the aforementioned second region.

[0026] In the above solution, the region covered by the light of the first light-emitting module further includes the regions on both sides of the target object, which can further achieve effective lighting of the road surface and improve driving safety.

[0027] In a second aspect, the present application provides a headlight, and the aforementioned headlight includes a first light-emitting module and a second light-emitting module;

[0028] The aforementioned first light-emitting module and the aforementioned second light-emitting module are pixelated light-emitting modules, and the pixels of the aforementioned first light-emitting module are higher than those of the aforementioned second light-emitting module;

[0029] The aforementioned first light-emitting module and the aforementioned second light-emitting module are used to emit light to form a pattern;

[0030] The pattern formed by the light emission of the aforementioned second light-emitting module includes a first region and a second region. The aforementioned first region is the region covered by the light of the aforementioned second light-emitting module, and the aforementioned second region is the region not covered by the light of the aforementioned second light-emitting module;

[0031] The target object is included in the second region described above. A third region is included between the target object and the vehicle lamp in the second region described above. The illumination of the first light-emitting module covers the third region.

[0032] In a possible implementation, the illumination range of the second light-emitting module is greater than the illumination range of the first light-emitting module.

[0038] In the embodiments of the present application, "a plurality of" means two or more. In the embodiments of the present application, "and / or" is used to describe the association relationship of associated objects, indicating three relationships that can exist independently. For example, A and / or B can represent: A exists alone, B exists alone, or A and B exist simultaneously. In the embodiments of the present application, the description methods such as "at least one (or at least one) of a1, a2,..., and an" include the case where any one of a1, a2,..., and an exists alone, and also include any combination of any plurality of a1, a2,..., and an. Each case can exist alone; for example, the description method of "at least one of a, b, and c" includes the cases of a alone, b alone, c alone, the combination of a and b, the combination of a and c, the combination of b and c, or the combination of a, b, and c.

[0039] In the present application, terms such as "first" and "second" are used to distinguish the same items or similar items with basically the same functions. It should be understood that there is no logical or temporal dependence relationship between "first", "second", and "nth", and the quantity and execution order are not limited. It should also be understood that although the following description uses terms such as first and second to describe various elements, these elements should not be limited by the terms. These terms are only used to distinguish one element from another element.

[0040] In various embodiments of the present application, if there is no special description and logical conflict, the terms and / or descriptions between the various embodiments are consistent and can be referenced to each other. The technical features in different embodiments can be combined to form new embodiments according to their inherent logical relationships.

[0041] In order to reduce the far - light shielding dark area, achieve anti - glare while illuminating the road surface in front of the vehicle itself, and improve driving safety, the embodiments of the present application provide a vehicle lamp system. The following is an exemplary introduction. Figures 1 to 11 Exemplary introduction.

[0042] In one possible implementation, the vehicle lamp system provided by the embodiments of the present application can be referred to, for example, as Figure 1 . Figure 1 The vehicle lamp system 100 shown can include a vehicle lamp 110 and a vehicle lamp controller 120. The vehicle lamp 110 can include a first light - emitting module 1101 and a second light - emitting module 1102.

[0043] Exemplarily, the vehicle lamp 110 can be, for example, the high - beam lamp of the vehicle.

[0044] Exemplarily, the first light - emitting module 1101 and the second light - emitting module 1102 are pixel - type light - emitting modules. And the pixels of the first light - emitting module 1101 are higher than those of the second light - emitting module 1102.

[0045] The above - mentioned pixel - type light - emitting module means that the light - emitting module can be composed of multiple light - emitting units, and the light - emitting unit can be simply referred to as a pixel unit. Each pixel unit can be individually controlled to be turned on or off. When a pixel unit is turned on, it indicates that the pixel unit is controlled to emit light. When a pixel unit is turned off, it indicates that the pixel unit is controlled so as not to emit light. By controlling the turning on or off of each pixel unit in the multiple pixel units, the light emitted by the light - emitting module can form various pattern shapes.

[0046] The fact that the pixels of the first light - emitting module 1101 are higher than those of the second light - emitting module 1102 indicates that the pixel density of the first light - emitting module 1101 is greater than that of the second light - emitting module 1102. For example, the first light - emitting module 1101 can achieve more fine - grained area lighting control.

[0047] Exemplarily, the above-mentioned first light-emitting module 1101 can be, for example, a light-emitting module based on digital light processing (DLP). This light-emitting module can include digital micromirror devices (DMD). Exemplarily, a matrix composed of a large number of small lenses is arranged on the DMD, and each small lens represents a pixel unit. By controlling the angle of movement of the small lenses, the light from a light source (such as a laser or an LED lamp) can be emitted outward (for example, emitted from a vehicle lamp), and this situation indicates that the pixel unit is turned on. Or, by controlling the angle of movement of the small lenses, the light can be absorbed and not emitted outward, and this situation indicates that the pixel unit is turned off. Exemplarily, millions or even more pixel units can be arranged on the DMD, so that million-pixel-level light emission control can be achieved.

[0048] Alternatively, exemplarily, the above-mentioned first light-emitting module 1101 can also be, for example, a light-emitting module based on reflective liquid crystal projection technology. This light-emitting module can include a liquid crystal on silicon (LCoS) chip. Millions of pixel electrodes (i.e., pixel units) can be integrated on the LCoS chip. By controlling these pixel units, million-pixel-level light emission control can be achieved in the same way.

[0049] It can be understood that the above introduction to the first light-emitting module 1101 is only an example and does not constitute a limitation on the embodiments of the present application. In a specific implementation, the first light-emitting module 1101 can also be other light-emitting modules that can achieve million-pixel-level light emission control, or can be other light-emitting modules with a higher number of pixels than the second light-emitting module 1102. The embodiments of the present application do not limit this.

[0050] Exemplarily, the above-mentioned second light-emitting module 1102 can be, for example, a light-emitting module including multiple LEDs. Each LED represents a pixel unit. By controlling the brightness (turning on) or darkness (turning off) of each of the multiple LEDs, the light emitted by the second light-emitting module 1102 can form various pattern shapes. Exemplarily, the multiple LEDs can be any number from 20 to 90 LEDs, for example, the second light-emitting module 1102 can include an LED matrix composed of 84 LEDs, etc. The embodiments of the present application do not limit the number of LEDs.

[0051] In a possible implementation, the maximum illumination range of the second light-emitting module 1102 is greater than that of the first light-emitting module 1101. Exemplarily, it is assumed that the maximum illumination range of the first light-emitting module 1101 is within the range covered by the first field of view (FOV) in front of the vehicle's head. It is assumed that the maximum illumination range of the second light-emitting module 1102 is within the range covered by the second field of view in front of the vehicle's head. Then the second field of view is greater than the first field of view. For example, the angle of the first field of view is between 10° and 14°, and the angle of the second field of view is between 30° and 40°. Exemplarily, taking the first field of view as 14° as an example, the maximum illumination range of the first light-emitting module 1101 is within the range of 7° to the left and right in front of the vehicle's head. Taking the second field of view as 40° as an example, the maximum illumination range of the second light-emitting module 1102 is within the range of 20° to the left and right in front of the vehicle's head. It can be understood that the introduction of the first field of view and the second field of view here is only an example and does not constitute a limitation on the embodiments of the present application. In a specific implementation, the first field of view and the second field of view can also be other values, and the embodiments of the present application do not limit this.

[0052] In a possible implementation, the maximum illumination ranges of the second light-emitting module 1102 and the first light-emitting module 1101 can cover a place dozens of meters to hundreds of meters in front of the vehicle's head. The specific coverage length is designed according to actual application requirements, and the embodiments of the present application do not limit this.

[0053] The above-mentioned headlight controller 120 can be used to control the first light-emitting module 1101 and the second light-emitting module 1102 to emit light to form corresponding patterns. The specific control logic can be exemplarily referred to the following introduction and will not be elaborated here for the time being.

[0054] Exemplarily, the above-mentioned headlight controller 120 can be integrated in the domain controller of the vehicle, for example. For example, it can be integrated in a vehicle control unit (VCU), a hybrid control unit (HCU), a vehicle domain controller (VDC), or an intelligent driving controller and other controllers. Or, the headlight controller 120 can be, for example, a controller independently set separately from these domain controllers. The embodiments of the present application do not limit this.

[0055] In a possible implementation, for example, it can be exemplarily referred to Figure 2 The above-mentioned headlight 110 can include a first headlight 110_1 and a second headlight 110_2. Exemplarily, among the first headlight 110_1 and the second headlight 110_2, one can be the left high beam of the vehicle, and the other can be the right high beam of the vehicle.

[0056] Exemplarily, the first vehicle lamp 110_1 described above may include a first light-emitting module 11011 and a second light-emitting module 11021. The second vehicle lamp 110_2 described above may include a first light-emitting module 11012 and a second light-emitting module 11022. For the introduction of the first light-emitting module 11011 and the first light-emitting module 11012, reference may be made to the description of the first light-emitting module 1101 above, which will not be elaborated here. For the introduction of the second light-emitting module 11021 and the second light-emitting module 11022, reference may be made to the description of the second light-emitting module 1102 above, which will not be elaborated here.

[0057] Exemplarily, the above Figure 2 The vehicle lamp controller 120 shown in may be used to control the first light-emitting module 11011, the second light-emitting module 11021, the first light-emitting module 11012, and the second light-emitting module 11022 to emit light to form corresponding patterns.

[0058] Exemplarily, in another possible implementation manner, the above first vehicle lamp 110_1 may only include the first light-emitting module 11011. The second vehicle lamp 110_2 may only include the first light-emitting module 11012. Then, the above vehicle lamp 110 may further include a third vehicle lamp. The third vehicle lamp includes the above second light-emitting module 1102.

[0059] In a possible implementation manner, for example, it can be exemplarily referred to Figure 3 , the above vehicle lamp controller 120 may include a first controller 1201 and a second controller 1202. Exemplarily, the first controller 1201 and the second controller 1202 may communicate with each other. Among them, the first controller 1201 may be used to control the first light-emitting module 1101 to emit light. The second controller 1202 may be used to control the second light-emitting module 1102 to emit light.

[0060] In a possible implementation manner, for example, it can be exemplarily referred to Figure 4 . Figure 4 In the vehicle lamp system 100 shown, the first controller 1201 may be used to control the high-pixel light-emitting modules to emit light, for example, to control the first light-emitting module 11011 and the first light-emitting module 11012 to emit light. The second controller 1202 may be used to control the low-pixel light-emitting modules to emit light, for example, to control the second light-emitting module 11021 and the second light-emitting module 11022 to emit light.

[0061] In a possible implementation manner, for example, it can be exemplarily referred to Figure 5 . Figure 5In the headlight system 100 shown, the first controller 1201 can be used to control the light-emitting modules of the first headlight 110_1 to emit light, for example, to control the first light-emitting module 11011 and the second light-emitting module 11021 to emit light. The second controller 1202 can be used to control the light-emitting modules of the second headlight 110_2 to emit light, for example, to control the first light-emitting module 11012 and the second light-emitting module 11022 to emit light.

[0062] In a possible implementation, for example, it can be exemplarily referred to Figure 6 . The headlight system 100 may further include a sensing module 130. Exemplarily, the sensing module 130 can be used to sense the position and / or type of an object around the vehicle. Then, the sensed position and / or type of the object are sent to the headlight controller 120, so that the headlight controller 120 can control the light emission of the light-emitting modules in the headlight based on the position and / or type of the object.

[0063] Exemplarily, the types of the above objects may include, for example, the types of various vehicles, pedestrians, animals, etc., and the embodiments of the present application do not limit this.

[0064] Exemplarily, the sensing module 130 may include a camera, a radar (such as a lidar, a microwave radar, or a millimeter-wave radar, etc.), or a combination of a camera and a radar.

[0065] In a possible implementation, the sensing module 130 may be, for example, a sensing module serving the advanced driving assistance system (ADAS) in the vehicle. After the sensing module obtains the position and / or type of the object, it can be sent by the ADAS controller to the above-mentioned headlight controller 120. Exemplarily, the ADAS controller may first send the position and / or type information to the vehicle integration unit (VIU) of the vehicle, and then the VIU forwards it to the headlight controller 120. For example, refer to Figure 7 shown. Here, the VIU 140 is equivalent to the gateway of the vehicle and is used to forward various information in the vehicle. Exemplarily, the VIU can also be called the vehicle intranet unit. It can be understood that these names are only examples and do not limit the embodiments of the present application.

[0066] In a possible implementation, the sensing module 130 may be, for example, a sensing module provided inside the headlight. Exemplarily, in combination with the above Figure 5 shown headlight system 100, sensing modules can be provided in both the first headlight 110_1 and the second headlight 110_2. For example, it can be exemplarily referred to Figure 8As shown in the figure. The perception module 130 may include a first perception module 1301 and a second perception module 1302. The first perception module 1301 may be disposed within the first vehicle headlight 110_1. The second perception module 1302 may be disposed within the second vehicle headlight 110_2. Since the first controller 1201 is used to control the light-emitting module of the first vehicle headlight 110_1 to emit light, after the first perception module 1301 obtains the position and / or type information of the object, it may send the position and / or type information to the first controller 1201. So that the first controller 1201 can control the light emission of the light-emitting module within the first vehicle headlight 110_1 based on the position and / or type of the object.

[0067] Similarly, since the second controller 1202 is used to control the light-emitting module of the second vehicle headlight 110_2 to emit light, after the second perception module 1302 obtains the position and / or type information of the object, it may send the position and / or type information to the second controller 1202. So that the second controller 1202 can control the light emission of the light-emitting module within the second vehicle headlight 110_2 based on the position and / or type of the object.

[0068] Exemplarily, in the above Figure 8 shown vehicle headlight system 100, if both the first vehicle headlight 110_1 and the second vehicle headlight 110_2 emit light outward, then in order to ensure that the light patterns emitted by the two vehicle headlights are consistent, the above first controller 1201 and second controller 1202 may perform synchronization processing on the received position and / or type information of the object. Exemplarily, the position and / or type information of the object sent by the perception module to the controller carries a timestamp, and the first controller 1201 and the second controller 1202 may synchronize and align based on the timestamps of the received position and / or type information. For example, the first controller 1201 and the second controller 1202 may perform interactive communication to negotiate and determine the timestamp of the position and / or type information to be used. Then, the first controller 1201 and the second controller 1202 respectively control the light emission of the corresponding light-emitting module based on the position and / or type information corresponding to the determined timestamp. It can be understood that the introduction of information synchronization here is only an example, and the embodiments of the present application may adopt any method of synchronization processing, and are not limited thereto.

[0069] Or, exemplarily, the perception module 130 may be disposed within one of the above first vehicle headlight 110_1 and second vehicle headlight 110_2. For example, it can be exemplarily referred to Figure 9 as shown in Figure 9 Still in combination with the above Figure 5The headlight system 100 shown will be introduced by way of example. After the perception module 130 obtains the position and / or type information of the object, it can send the position and / or type information to the first controller 1201 and the second controller 1202. So that the first controller 1201 can control the light emission of the light-emitting module in the first headlight 110_1 based on the position and / or type of the object, and the second controller 1202 can control the light emission of the light-emitting module in the second headlight 110_2 based on the position and / or type of the object. Exemplarily, as above, in order to ensure that the light patterns emitted by the two headlights are consistent, the first controller 1201 and the second controller 1202 can perform synchronization processing on the received position and / or type information of the object. For specific reference, please refer to the above exemplary description, which will not be elaborated here.

[0070] Alternatively, exemplarily, in the implementation scheme where the perception module 130 is disposed in one of the first headlight 110_1 and the second headlight 110_2, after the perception module 130 obtains the position and / or type information of the object, it can send the position and / or type information to one of the first controller 1201 and the second controller 1202. For example, assuming that the perception module 130 is disposed in the first headlight 110_1, then the perception module 130 can send the obtained position and / or type information of the object to the first controller 1201, for example, see Figure 10 . Or, for example, assuming that the perception module 130 is disposed in the second headlight 110_2, then the perception module 130 can send the obtained position and / or type information of the object to the second controller 1202, for example, see Figure 11 . Exemplarily, in a possible implementation manner, taking Figure 10 as an example, after the first controller 1201 obtains the position and / or type information of the object, it can send the position and / or type information to the second controller 1202. Optionally, in this implementation manner, the second controller 1202 controls the light-emitting module in the second headlight 110_2 to emit light based on the position and / or type information received from the first controller 1201. And the first controller 1201 also controls the light-emitting module in the second headlight 110_2 to emit light based on the position and / or type information sent to the second controller 1202. Thus, additional synchronization processing can be avoided. Figure 11 Similarly, it will not be elaborated.

[0071] It can be understood that although the above Figures 8 to 11 is introduced by taking the headlight system 100 shown above as an example, the above setting manner of the perception module 130 can be similarly combined and applied to the headlight system 100 shown above Figure 5 , or Figure 3 or Figure 4 , which will not be elaborated here.

[0072] In a possible implementation, the headlight system 100 provided by the embodiments of the present application belongs to an ADB system.

[0073] It can be understood that the headlight system 100 shown above is only an example and does not constitute a limitation to the embodiments of the present application. Figures 1 to 11 The headlight system 100 shown above is only an example and does not constitute a limitation to the embodiments of the present application.

[0074] Exemplarily, based on the headlight system 100 introduced above, through the cooperation of high and low pixel light-emitting modules, the far-light shielding dark area formed by the low pixel light-emitting module is reduced, and high-precision far-light shielding in front of the vehicle (the main visual area of the driver) is achieved. It can not only prevent dazzling of oncoming or oncoming target objects in front of the vehicle but also illuminate the road surface in front of the vehicle itself. Exemplarily, the target object may include various types of vehicles (including small, medium, and large passenger cars, trucks, sanitation vehicles, trailers, bicycles, motorcycles, and tricycles, etc.), pedestrians, or animals, etc. The embodiments of the present application do not limit this. For ease of understanding, the following is an exemplary introduction in combination with Figures 12 to 16 Exemplary introduction.

[0075] Exemplarily, Figures 12 to 16 The figure shows a schematic diagram of the effect of high beam control achieved after adopting the implementation solution of the present application. Figure 12 And Figure 13 The figure shows a small passenger car as an example of the target object. Figure 14 And Figure 15 The figure shows a motorcycle as an example of the target object. Among them, Figure 12 And Figure 14 The target object shown is moving towards the vehicle itself (i.e., the vehicle including the headlight system 100 above). Figure 13 And Figure 15 The target object shown is moving in the same direction as the vehicle itself. Figure 16 The target object shown exemplarily shows two (Target Object 1 and Target Object 2). Among them, Target Object 1 is moving towards the vehicle itself, and Target Object 2 is moving in the same direction as the vehicle itself.

[0076] In Figures 12 to 16 , the pattern formed by the light emission of the second light-emitting module of the vehicle itself includes a first region and a second region. The second light-emitting module may be, for example, at least one of the above-mentioned second light-emitting module 11021 and second light-emitting module 11022. The first region is, for example, Figures 12 to 16 In, the region in front of the vehicle head surrounded by dashed line ① and dashed line ② except for the second region. The second region is, for example, Figures 12 to 16Among them, the area in front of the vehicle head surrounded by the dashed line ③ and the dashed line ④. The first area is the area covered by the light of the second light-emitting module. The second area is the area not covered by the light of the second light-emitting module. It can be understood that the above-mentioned first area and second area are within the maximum illumination range of the second light-emitting module.

[0077] In addition, it can also be seen that the target object is located in the above-mentioned second area. The area between the target object and the vehicle lights within the second area belongs to the third area. The light of the first light-emitting module of the vehicle covers this third area. The first light-emitting module can be, for example, at least one of the above-mentioned first light-emitting module 11011 and the first light-emitting module 11012. Optionally, the third area can also include the areas on both sides of the target object within the second area, that is, the light of the first light-emitting module can cover the areas on both sides of the target object within the second area. And since the lights of both the first light-emitting module and the second light-emitting module do not cover the target object itself, therefore, a high-beam shielding dark area is formed at the position of the target object itself. Exemplarily, the high-beam shielding dark area can be, for example, within the area of the target object itself and the vehicle width of the target object plus the first length. The first length can be, for example, between 1 meter and 2 meters. Thus, high-precision high-beam shielding can be achieved, effectively preventing high-beam glare. In addition, since the aforementioned third area is covered by the light of the first light-emitting module, the road surface in front of the vehicle is effectively illuminated. Coupled with the illumination range covered by the light of the second light-emitting module, it provides good illumination of the surrounding environment for the vehicle, greatly improving driving safety.

[0078] It can be understood that the above Figures 12 to 16 The effect of the high-beam control shown is only for illustration and does not constitute a limitation to the embodiments of the present application. In addition, the above mainly takes one or two target objects as examples. In specific implementation, the solution of the present application can also be applied to the scenario of high-beam shielding for more target objects, which will not be elaborated here one by one.

[0079] In specific implementation, the effect of the high-beam control introduced above is achieved by the above-mentioned headlight controller 120 controlling the light-emitting modules in the headlights to emit light based on the position and / or type of the above-mentioned target object. The implementation process of the control is introduced below by way of example.

[0080] In one possible implementation manner, for example, refer to Figure 17 , which exemplarily shows a schematic diagram of a possible high-beam control process. Exemplarily, Figure 17 Each step of the high-beam control process shown can be executed by the above-mentioned headlight controller 120, for example.

[0081] In Figure 17In this case, the adaptive high beam control state machine can be used to determine whether to activate the light-emitting module, for example, to determine whether to turn on the high beam of the host vehicle. Exemplarily, the adaptive high beam control state machine can determine based on the driving speed of the host vehicle and / or the brightness of the environment, etc. For example, when the driving speed reaches a preset speed threshold and / or the ambient brightness is less than a preset brightness threshold, etc., the adaptive high beam control state machine can send an activation signal to activate the first light-emitting module and the second light-emitting module.

[0082] After the first light-emitting module and the second light-emitting module are activated, the headlight controller can receive the position information of the target object. Exemplarily, the headlight controller can periodically receive the position information of the target object to achieve tracking and prediction of the target object. After predicting the position information of the target object, coordinate transformation can be performed based on the predicted position information. Exemplarily, the predicted position information can be represented, for example, by a preset coordinate system. The preset coordinate system can be, for example, the coordinate system of the vehicle itself or the world coordinate system, etc. There is a preset correspondence between the preset coordinate system and the pixel coordinate system of the first light-emitting module and the pixel coordinate system of the second light-emitting module. First pixel coordinates and second pixel coordinates can be obtained through coordinate transformation. Among them, the first pixel coordinates include the coordinates of the pixel units for emitting light in the first light-emitting module, and the second pixel coordinates include the coordinates of the pixel units for emitting light in the second light-emitting module.

[0083] Exemplarily, in a possible implementation manner, before performing the coordinate transformation between the preset coordinate system and the pixel coordinate system of the second light-emitting module, in order to ensure that the two light-emitting modules emit light simultaneously, delay control can be performed first.

[0084] After the headlight controller obtains the first pixel coordinates, it can construct the high beam occlusion dark area based on the first pixel coordinates. That is, the pixel units in the first light-emitting module that hit the high beam occlusion dark area are identified. Then, control these pixel units that hit the high beam occlusion dark area to turn off, and control some or all of the pixel units in the first light-emitting module other than these pixel units to turn on, so that the light of the first light-emitting module can cover the third area.

[0085] After the headlight controller obtains the second pixel coordinates, it can control the corresponding pixel units in the second light-emitting module to turn on based on the second pixel coordinates, and control the pixel units other than these to turn off. So that the pattern formed by the light emission of the second light-emitting module includes the first area and the second area.

[0086] Exemplarily, in another possible implementation, the first pixel coordinates may include the coordinates of the pixel units to be turned off in the first light-emitting module, and the second pixel coordinates may include the coordinates of the pixel units to be turned off in the second light-emitting module. Knowing which pixel units are turned off, the remaining pixel units can then be controlled to turn on. Similarly, the above high-beam control effect can also be achieved.

[0087] It can be understood that the above Figure 17 shown high-beam control process is only an illustration and does not constitute a limitation on the embodiments of the present application. In a specific implementation, other control processes may also be used to achieve the above high-beam control effect, and the embodiments of the present application do not limit this.

[0088] In another possible implementation, after the first light-emitting module and the second light-emitting module are activated, the vehicle lamp controller may also receive the type information of the above target object. When the type information indicates that the target object belongs to a preset high-beam shielding object type, the vehicle lamp controller then continues to perform subsequent high-beam shielding operations such as tracking and prediction. If the type information indicates that the target object does not belong to the preset high-beam shielding object type, then the vehicle lamp controller does not perform subsequent high-beam shielding operations. Exemplarily, the preset high-beam shielding object type may include various types of vehicles, pedestrians, animals, etc., and the embodiments of the present application do not limit this.

[0089] The embodiments of the present application further provide a vehicle, which may include the vehicle lamp system 100 in any of the above possible implementations.

The order of execution of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
