The terms "first," "second," and the like in this disclosure are used for distinguishing between similar elements or items having substantially the same function and function, and it should be understood that there is no logical or chronological dependency between the terms "first," "second," and "n," and that there is no limitation on the amount and order of execution. It will be further understood that, although the following description uses the terms first, second, etc. 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.
In various embodiments of the application, where terminology and/or descriptions of the various embodiments are consistent and may be referred to each other, unless specifically indicated as such and where logical conflict, features of different embodiments may be combined to form new embodiments in accordance with their inherent logical relationships.
In order to reduce the dark space shielded by the high beam, realize the anti-dazzle purpose and illuminate the front road surface of the automobile so as to improve the driving safety, the embodiment of the application provides an automobile lamp system. Exemplary description will be made below with reference to fig. 1 to 11.
In a possible implementation manner, for example, fig. 1 may be referred to as a vehicle lamp system provided in an embodiment of the present application. The lamp system 100 shown in fig. 1 may include a lamp 110 and a lamp controller 120. The vehicle lamp 110 may include a first light emitting module 1101 and a second light emitting module 1102.
The lamp 110 may be, for example, a high beam of a vehicle.
The first light emitting module 1101 and the second light emitting module 1102 are pixel light emitting modules. And the pixels of the first light emitting module 1101 are higher than the pixels of the second light emitting module 1102.
The pixel type light emitting module mentioned above means that the light emitting module may be composed of a plurality of units for emitting light, and the units for emitting light may be simply referred to as pixel units. Each pixel cell may be individually controlled to be on or off. The pixel cell being turned on indicates that the pixel cell is controlled for emitting light. The pixel cell turned off indicates that the pixel cell is controlled so as not to emit light. By controlling the on or off of each pixel unit in the plurality of pixel units, the light emitted by the light emitting module can form various pattern shapes.
The pixels of the first light emitting module 1101 are higher than the pixels of the second light emitting module 1102, which indicates that the pixel density of the first light emitting module 1101 is higher than the pixel density of the second light emitting module 1102. For example, the first lighting module 1101 may implement lighting control of a finer grained region.
The first light emitting module 1101 may be, for example, a light emitting module based on digital light processing (DIGITAL LIGHT processing, DLP). The light emitting module may include a digital micromirror device (digital micromirror devices, DMD). Illustratively, a matrix of a large number of small mirrors, each representing a pixel cell, is provided on the DMD. Light from a light source (laser or LED lamp, etc.) may be emitted outwards (e.g. from a car lamp) by controlling the angle of movement of the small mirror, which indicates that the pixel unit is on. Or by controlling the angle of the small lens movement, the light can be absorbed and not emitted to the outside, which indicates that the pixel unit is off. Illustratively, millions or even more pixel cells may be provided on a DMD, such that light emission control at the millions of pixel level may be achieved.
Or, for example, the first light emitting module 1101 may be a light emitting module based on a reflective liquid crystal projection technology. The light emitting module may include a liquid crystal on silicon (liquid crystal on silicon, LCoS) chip. Millions of pixel electrodes (i.e., pixel cells) may be integrated on an LCoS chip. By controlling these pixel units, light emission control at the megapixel level can be realized in the same manner.
It is to be understood that the above description about the first light emitting module 1101 is only an example, and does not constitute a limitation of the embodiments of the present application. In a specific implementation, the first light emitting module 1101 may be another light emitting module capable of performing light emission control at a megapixel level, or may be a light emitting module having other pixels higher than the second light emitting module 1102. The embodiments of the present application are not limited in this regard.
The second light emitting module 1102 may be, for example, a light emitting module including a plurality of LEDs. Each LED represents a pixel cell. By controlling the light (on) or dark (off) of each of the plurality of LEDs, the light emitted from the second light emitting module 1102 may form various pattern shapes. The plurality of LEDs may be any number of 20 to 90 LEDs, for example, the second light emitting module 1102 may include an LED matrix composed of 84 LEDs, or the like, and the number of LEDs is not limited in the embodiment of the present application.
In a possible implementation manner, the maximum illumination range of the second light emitting module 1102 is greater than the maximum illumination range of the first light emitting module 1101. Illustratively, it is assumed that the maximum illumination range of the first light emitting module 1101 is within a range covered by a first field of view (FOV) in front of the vehicle, and that the maximum illumination range of the second light emitting module 1102 is within a range covered by a second field of view in front of the vehicle. The second field of view is greater than the first field of view. For example, the first angle of view is between 10 ° and 14 ° and the second angle of view is between 30 ° and 40 °. Illustratively, taking the first field angle as 14 ° as an example, the maximum illumination range of the first light emitting module 1101 is within a range of 7 ° each around the front of the vehicle. Taking the second angle of view as an example, the maximum illumination range of the second light emitting module 1102 is within 20 ° of each of the front, the left and the right of the head of the vehicle. It is to be understood that the description herein of the first angle of view and the second angle of view is merely exemplary and is not to be construed as limiting the embodiments of the application. In a specific implementation, the first field angle and the second field angle may also be other values, which are not limited in this embodiment of the present application.
In a possible implementation manner, the maximum illumination range of the second light emitting module 1102 and the maximum illumination range of the first light emitting module 1101 may cover a place of several tens meters to several hundreds meters in front of the vehicle head. The specific coverage length is designed according to practical application requirements, and the embodiment of the application is not limited to this.
The lamp controller 120 may be configured to control the first light emitting module 1101 and the second light emitting module 1102 to emit light to form corresponding patterns. Specific control logic may be exemplified by the following description and will not be described in detail herein.
The lamp controller 120 may be integrated into a domain controller of a vehicle, for example. For example, integrated into a vehicle control unit (vehicle control unit, VCU), a hybrid control unit (hybrid control unit, HCU), a vehicle domain controller (vehicledomain controller, VDC), or a controller such as an intelligent driving controller. Or the lamp controller 120 may be a controller separately provided from the domain controllers, for example. The embodiments of the present application are not limited in this regard.
In one possible implementation, for example, reference may be made to fig. 2. The vehicle lamp 110 may include a first lamp 110_1 and a second lamp 110_2. Illustratively, one of the first and second lights 110_1 and 110_2 may be a left-side high beam of the vehicle and the other may be a right-side high beam of the vehicle.
The first lamp 110_1 may include a first light emitting module 11011 and a second light emitting module 11021. The second lamp 110_2 may include a first light emitting module 11012 and a second light emitting module 11022. The first light emitting module 11011 and the first light emitting module 11012 may refer to the description of the first light emitting module 1101, which is not repeated here. The second light emitting module 11021 and the second light emitting module 11022 can be described with reference to the second light emitting module 1102, which is not described herein.
For example, the lamp controller 120 shown in fig. 2 described above may be used to control the first and second light emitting modules 11011 and 11021, and the first and second light emitting modules 11012 and 11022 to emit light to form corresponding patterns.
For example, in another possible embodiment, the first lamp 110_1 may include only the first light emitting module 11011. The second lamp 110_2 may include only the first light emitting module 11012. The lamp 110 may then further comprise a third lamp. The third lamp includes the second light emitting module 1102.
In one possible implementation, for example, referring to fig. 3, the lamp controller 120 may include a first controller 1201 and a second controller 1202. The first controller 1201 and the second controller 1202 may illustratively communicate with each other. Wherein the first controller 1201 may be used to control the first light emitting module 1101 to emit light. The second controller 1202 may be configured to control the second light emitting module 1102 to emit light.
In one possible implementation, for example, reference may be made to fig. 4. In the vehicle lamp system 100 shown in fig. 4, the first controller 1201 may be used to control the light emitting modules of the high pixels 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 light emitting modules of the low pixels to emit light, for example, to control the second light emitting module 11021 and the second light emitting module 11022 to emit light.
In one possible implementation, for example, reference may be made to fig. 5. In the vehicle lamp system 100 shown in fig. 5, the first controller 1201 may be used to control the light emitting modules of the first vehicle lamp 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 may be configured to control the light emitting modules of the second lamp 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.
In one possible implementation, for example, see fig. 6 for an example. The lamp system 100 may also include a perception module 130. For example, the perception module 130 may be used to perceive the location and/or type of objects surrounding the vehicle. The perceived location and/or type of the object is then transmitted to the lamp controller 120 so that the lamp controller 120 can control the lighting of the lighting modules within the lamp based on the location and/or type of the object.
By way of example, the types of objects described above may include, for example, various vehicle types, pedestrians or animals, and the like, to which embodiments of the present application are not limited.
Illustratively, the sensing module 130 may include a camera, a radar (e.g., a lidar, a microtank or millimeter wave radar, etc.), or a combination of a camera and a radar.
In one possible implementation, the sensing module 130 may be, for example, a sensing module in a vehicle that serves an advanced driving assistance system (ADVANCED DRIVING ASSISTANCE SYSTEM, ADAS). The sensing module, after acquiring the position and/or type of the object, may be sent by the ADAS controller to the lamp controller 120. For example, the ADAS controller may send the location and/or type information to a vehicle integrated unit (vehicle integration unit, VIU) of the vehicle before forwarding by the VIU to the lamp controller 120. For example, referring to fig. 7, VIU 140 here corresponds to a gateway of a vehicle for forwarding various information in the vehicle. The VIU may also be referred to as a vehicle intranet unit (VEHICLE INTRANET unit), for example. It is to be understood that these names are merely exemplary and not limiting of the embodiments of the present application.
In one possible implementation, the sensing module 130 may be, for example, a sensing module disposed inside a vehicle lamp. For example, in conjunction with the vehicle lamp system 100 shown in fig. 5, a sensing module may be provided in each of the first and second vehicle lamps 110_1 and 110_2. For example, see fig. 8. The perception module 130 may include a first perception module 1301 and a second perception module 1302. The first sensing module 1301 may be disposed in the first lamp 110_1. The second perception module 1302 may be disposed within the second vehicle lamp 110_2. Since the first controller 1201 is configured to control the light emitting module of the first headlight 110_1 to emit light, the first sensing module 1301 may transmit the position and/or type information of the object to the first controller 1201 after acquiring the position and/or type information. So that the first controller 1201 can control the light emission of the light emitting module within the first lamp 110_1 based on the position and/or type of the object.
Similarly, since the second controller 1202 is configured to control the light emitting module of the second lamp 110_2 to emit light, the second sensing module 1302 may send the position and/or type information to the second controller 1202 after acquiring the position and/or type information of the object. So that the second controller 1202 can control the lighting of the lighting modules within the second lamp 110_2 based on the location and/or type of the object.
For example, in the vehicle lamp system 100 shown in fig. 8, if the first lamp 110_1 and the second lamp 110_2 emit light outwards, the first controller 1201 and the second controller 1202 may perform synchronization processing for the received position and/or type information of the object in order to ensure that the light patterns emitted by the two vehicle lamps are consistent. Illustratively, the location and/or type information of the object sent to the controller by the perception module carries a time stamp, and the first controller 1201 and the second controller 1202 may be synchronously aligned based on the received time stamp of the location and/or type information. For example, the first controller 1201 and the second controller 1202 may perform an interactive communication negotiation to determine a timestamp of the employed location and/or type information. Then, the first controller 1201 and the second controller 1202 each control the light emission of the corresponding light emitting module based on the position and/or type information corresponding to the determined time stamp. It should be understood that the description of information synchronization is only an example, and embodiments of the present application may use any method of synchronization processing, which is not limited thereto.
Or, for example, the perception module 130 may be disposed within one of the first and second vehicle lights 110_1, 110_2 described above. For example, referring to fig. 9, fig. 9 is still described in exemplary combination with the lamp system 100 described above and shown in fig. 5. After the sensing module 130 obtains the location and/or type information of the object, the location and/or type information may be sent 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 within the first vehicle lamp 110_1 based on the position and/or type of the object, and so that the second controller 1202 can control the light emission of the light emitting module within the second vehicle lamp 110_2 based on the position and/or type of the object. Illustratively, as above, to ensure that the light patterns emitted by the two vehicle lights are consistent, the first controller 1201 and the second controller 1202 may perform synchronization processing with respect to the received position and/or type information of the object. Reference may be made in particular to the above-mentioned exemplary description, which is not repeated here.
Or, for example, in the implementation of setting the sensing module 130 in one of the first lamp 110_1 and the second lamp 110_2, after the sensing module 130 obtains the position and/or type information of the object, the position and/or type information may be sent to one of the first controller 1201 and the second controller 1202. For example, assuming that the perception module 130 is disposed within the first headlight 110_1, the perception module 130 may transmit the acquired position and/or type information of the object to the first controller 1201, for example, see fig. 10. Or, for example, assuming that the perception module 130 is disposed within the second vehicle lamp 110_2, the perception module 130 may transmit the acquired location and/or type information of the object to the second controller 1202, for example, see fig. 11. Illustratively, in one possible implementation, taking fig. 10 as an example, after the first controller 1201 acquires the location and/or type information of the object, the location and/or type information may be sent to the second controller 1202. Optionally, in this implementation, the second controller 1202 controls the light emitting modules within the second lamp 110_2 to emit light based on the location and/or type information received from the first controller 1201. And the first controller 1201 also controls the light emitting module in the second lamp 110_2 to emit light based on the position and/or type information sent to the second controller 1202. So that no additional synchronization process is required. Fig. 11 is the same and is not repeated.
It should be understood that although fig. 8 to 11 are described with reference to the vehicle lamp system 100 shown in fig. 5, the same manner of disposing the sensing module 130 may be applied to the vehicle lamp system 100 shown in fig. 3 or 4, and will not be repeated here.
In a possible implementation manner, the vehicle lamp system 100 provided in the embodiment of the present application belongs to an ADB system.
It should be understood that the vehicle lamp system 100 shown in fig. 1 to 11 is merely an example, and is not limited to the embodiment of the present application.
Illustratively, based on the vehicle lamp system 100 described above, the high-beam shielding dark area formed by the low-pixel light emitting module is reduced by the cooperation of the high-low-pixel light emitting module, so that high-precision high-beam shielding in front of the vehicle (main vision area of the driver) is realized, and the effect that glare is not generated on the target objects in the same direction or opposite directions in the front of the vehicle and the illumination effect of the front road surface of the vehicle is realized. By way of example, the target object may include, for example, various types of vehicles (including small, medium, large passenger cars, trucks, sanitation vehicles, trailers, bicycles, motorcycles, tricycles, and the like), pedestrians or animals, and the like, to which embodiments of the present application are not limited. For ease of understanding, the following is an exemplary description in connection with fig. 12-16.
Fig. 12 to 16 are schematic views illustrating the effect of the high beam control achieved by adopting the embodiment of the present application. Fig. 12 and 13 show examples of a small passenger car as a target object. Fig. 14 and 15 show an example of a motorcycle as a target object. The target object shown in fig. 12 and 14 is moved toward the vehicle (i.e., the vehicle including the lamp system 100 described above). The target object shown in fig. 13 and 15 runs in the same direction as the own vehicle. The target objects shown in fig. 16 exemplarily show two (target object 1 and target object 2). Wherein the target object 1 runs opposite to the own vehicle, and the target object 2 runs opposite to the own vehicle.
In fig. 12 to 16, the pattern formed by the light emission of the second light emitting module of the host vehicle includes a first region and a second region. The second light emitting module may be at least one of the second light emitting module 11021 and the second light emitting module 11022. The first region is, for example, a region other than the second region among regions in front of the vehicle head surrounded by the broken line ① and the broken line ② in fig. 12 to 16. The second region is, for example, a region in front of the vehicle head surrounded by a broken line ③ and a broken line ④ in fig. 12 to 16. The first area is an illumination coverage area of the second light-emitting module. The second area is an area uncovered by the illumination of the second light-emitting module. It can be understood that the first area and the second area are within the maximum illumination range of the second light emitting module.
Furthermore, it can be seen that the target object is located in the above-mentioned second region. The area between the target object and the lamps of the own vehicle in the second area belongs to a third area. The illumination of the first light-emitting module of the own vehicle covers the third area. The first light emitting module may be, for example, at least one of the first light emitting module 11011 and the first light emitting module 11012 described above. Optionally, the third area may further include areas on both sides of the target object in the second area, i.e. the illumination of the first light emitting module may cover areas on both sides of the target object in the second area. The illumination of the first light-emitting module and the illumination of the second light-emitting module do not cover the target object, so that a high beam shielding dark area is formed at the position of the target object. The high beam masking dark region may be, for example, within the target itself and the region of the target vehicle width plus the first length. The first length may be, for example, between 1 meter and 2 meters. Therefore, high-precision high-beam shielding can be realized, and high-beam dazzling can be effectively prevented. In addition, as the third area is covered by the illumination of the first light-emitting module, the illumination of the road surface in front of the bicycle is effectively realized. And in addition, the range covered by the illumination of the second light-emitting module provides good illumination of surrounding environment for the vehicle, so that the driving safety is greatly improved.
It will be appreciated that the effect of the high beam control shown in fig. 12 to 16 is merely illustrative and not limiting of the embodiments of the present application. In addition, the above is mainly exemplified by one or two target objects, and in a specific implementation, the scheme of the present application may also be applicable to a scenario where a high beam is shielded for more target objects, which is not described herein in detail.
In a specific implementation, the effect of the above-described high beam control is achieved by the vehicle lamp controller 120 controlling the light emitting module in the vehicle lamp to emit light based on the position and/or type of the target object. The implementation of the control is described in the following by way of example.
In one possible implementation, for example, see fig. 17, a schematic diagram of one possible high beam control flow is shown. Illustratively, the steps of the high beam control flow shown in fig. 17 may be performed by the lamp controller 120 described above, for example.
In fig. 17, an adaptive high beam control state machine may be used to determine whether to activate a lighting module, for example, to determine whether to turn on a high beam of a host vehicle. For example, the adaptive high beam control state machine may be determined based on the traveling speed of the own vehicle and/or the brightness of the environment, etc. For example, if the running speed reaches a preset speed threshold and/or the ambient brightness is less than a preset brightness threshold, the adaptive high beam control state machine may send an activation signal to activate the first light emitting module and the second light emitting module.
After the first light emitting module and the second light emitting module are activated, the vehicle lamp controller may receive the position information of the target object. For example, the vehicle lamp controller may periodically receive the position information of the target object to implement tracking prediction of the target object. After the position information of the target object is predicted, coordinate conversion may be performed based on the predicted position information. The predicted position information may be represented by a preset coordinate system, for example. The preset coordinate system may be, for example, a coordinate system of the vehicle itself or a world coordinate system. The preset coordinate system has a preset corresponding relation with the pixel coordinate system of the first light-emitting module and the pixel coordinate system of the second light-emitting module. The first pixel coordinates and the second pixel coordinates can be obtained by coordinate conversion. The first pixel coordinates include coordinates of a pixel unit used for emitting light in the first light emitting module, and the second pixel coordinates include coordinates of a pixel unit used for emitting light in the second light emitting module.
For example, in one possible implementation, before performing the coordinate conversion 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 at the same time, time delay control may be performed.
After the car light controller obtains the first pixel coordinates, the high beam shielding dark area can be constructed based on the first pixel coordinates. The pixel unit in the high beam shielding dark area in the first light emitting module is determined. And then, controlling the pixel units which strike in the high beam shielding dark area to be closed, and controlling part or all of the pixel units except the pixel units in the first light emitting module to be opened so that the illumination of the first light emitting module can cover the third area.
After the vehicle lamp controller obtains the second pixel coordinates, the vehicle lamp controller can control the development of the corresponding pixel units in the second light-emitting module based on the second pixel coordinates and control the other pixel units to be turned off. The pattern formed by the second light-emitting module emits light comprises the first area and the second area.
In another possible implementation manner, the first pixel coordinates may include coordinates of a pixel unit for turning off in the first light emitting module, and the second pixel coordinates may include coordinates of a pixel unit for turning off in the second light emitting module. Knowing which pixel cells are off, the remaining pixel cells can then be controlled to turn on. The above-described high beam control effect can also be achieved.
It should be understood that the above-mentioned high beam control flow shown in fig. 17 is only an illustration, and is not limited to the embodiment of the present application. In a specific implementation, other control flows may be used to implement the above-mentioned high beam control effect, which is not limited in this embodiment of the present application.
In another possible implementation manner, after the first light emitting module and the second light emitting module are activated, the vehicle lamp controller may further receive the type information of the target object. And under the condition that the type information indicates that the target object belongs to the preset high beam shielding object type, the car lamp controller continues to execute the follow-up tracking prediction and other high beam shielding operations. If the type information indicates that the target object does not belong to the preset far-reaching headlamp shielding object type, the vehicle lamp controller does not execute the follow-up far-reaching headlamp shielding operation. By way of example, the predetermined high beam blocking object type may include various types of vehicles, pedestrians, animals, and the like, to which the embodiment of the present application is not limited.
Embodiments of the present application also provide a vehicle that may include the lamp system 100 in any of the possible implementations described above.
