Definitions

  • Embodiments of the present disclosure relate to an in-vehicle system and a vehicle.
  • Vehicles often use safe driving components while driving. For example, cars often use parts such as lights and rearview mirrors during driving, but these components have obvious safety hazards.
  • the rear view mirror can help the car driver to observe the environment of a part of the periphery of the vehicle body (the visual area of the rear view mirror).
  • the rearview mirror cannot assist the driver of the vehicle to observe the environment at all positions around the body, that is, there is a visual blind zone between the visual zones of the rearview mirror, and the visual blind zone is a car accident.
  • the rear view mirror inside the vehicle body reflects part of the strong light into the eyes of the driver of the vehicle.
  • the strong light not only affects the driver's mood, but also makes the driver's eyes need to adapt to the constant light environment and the low-light environment to switch, which makes the driver's eyes easy to fatigue, thereby increasing the probability of accidents.
  • At least one embodiment of the present disclosure provides an in-vehicle system including a vehicle light system.
  • the lamp system includes a redirecting unit or/and a light intensity adjusting unit and a vehicle lamp; the vehicle lamp is disposed on a front side of the vehicle body and configured to emit light; the redirecting unit is disposed at the headlight a light exiting side, and configured to change a transmission direction of the light emitted by the vehicle lamp incident thereon; and the light intensity adjusting unit is configured to adjust an intensity of the outgoing light of the vehicle light.
  • the vehicle lamp includes a left side area, an intermediate area, and a right side area; the vehicle light system further includes a first control unit, the first control unit It is configured to control the transmission direction and/or intensity of the outgoing light of the vehicle light by controlling the redirecting unit and/or the light intensity adjusting unit.
  • the redirecting unit is configured at least such that the emitted light of the left side area or the right side area of the headlight is respectively directed to the vehicle Left front or right front of the body.
  • the redirecting unit is further configured to cause the emitted light of the vehicle lamp to tilt toward a lower side of the front side of the vehicle body.
  • the vehicle lamp includes a first vehicle lamp and a second vehicle lamp, the first vehicle lamp being disposed on a left front side of the vehicle body, and including a left side area and a first intermediate area, the second vehicle light being disposed on a right front side of the vehicle body, and including the right side area and a second intermediate area, the intermediate area including the first intermediate area And the second intermediate region;
  • the redirecting unit includes a first redirecting unit and a second redirecting unit, the first redirecting unit is disposed on a light exiting side of the first vehicle light, and configured to be at least configured to change An outgoing direction of the outgoing light of the left side region of the first vehicle lamp such that the emitted light of the left side region is directed toward the left front of the vehicle body;
  • the second redirecting unit is disposed at the a light exiting side of the second vehicle light, and configured to change at least an exit direction of the outgoing light of the right side region of the second vehicle light such that
  • the first redirecting unit is further configured to cause the emitted light of the first intermediate region of the first vehicle to be directed toward the vehicle body Directly or causing the emitted light of the first intermediate region to be inclined toward the right front side of the vehicle body, the angle of the emitted light of the first intermediate region being inclined to the right front side of the vehicle body is less than 2 degrees;

Description

车载***和交通工具 技术领域
本公开的实施例涉及一种车载***和交通工具。
背景技术
交通工具在驾驶中，会经常使用安全驾驶部件，例如，汽车在驾驶中会经常用到车灯、后视镜等部件，但上述部件存在着明显的安全隐患。
例如，尽管后视镜可以帮助汽车驾驶人员观察车体周边的部分区域(后视镜的视觉区)的环境。但是，如果视线受到遮挡，则后视镜无法协助汽车驾驶人员观察车体周边所有位置处的环境，也即是后视镜的视觉区之间存在着视觉盲区，并且上述视觉盲区是引发车祸的主要因素之一。
又例如，在车体后方车辆的车灯发出强光情况下(例如，后方车辆开启远光灯)，车体内部的后视镜会将部分强光反射到车内驾驶人员的眼睛中，上述强光不仅会影响驾驶人员心情，还会使得驾驶人员的眼睛需要适应强光环境和弱光环境的不断切换，进而使得驾驶人员的眼睛容易疲劳，由此提高了事故发生的几率。
再例如，两辆车辆在夜间会车时，为了减少己方车灯对对方驾驶人员的干扰，已方驾驶人员需要在两辆会车车辆的车距较近时及时将远光灯切换为近光灯；在对方车辆通过时，还需要及时地将近光灯切换回远光灯，以更好的观察远方的道路。然而，频繁地切换远关灯和近光灯会分散驾驶人员的注意力，由此降低了驾驶的安全性。因此，亟需一种能够提高驾驶安全性的车载***。

为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。

本公开的实施例提供了一种车载***和交通工具，该车载***可以应用于交通工具的驾驶中，并可以提高交通工具驾驶的安全性。本申请的实施例以汽车作为交通工具为例对实施例进行具体说明，但本申请的实施例提供的车载***不限于仅应用于汽车。
本公开的至少一个实施例还提供了一种车载***，该车载***包括车灯***。车灯***包括变向单元或/和光强调节单元以及车灯；车灯设置在车体前侧，且配置为出射光线；变向单元设置在车灯的出光侧，且配置为改变入 射其上的、车灯出射的光线的传输方向；以及光强调节单元配置为调节车灯的出射光线的强度。例如，根据实际应用需求，该车灯***还可以包括第一控制单元，第一控制单元配置为通过控制变向单元和/或光强调节单元来控制车灯的出射光线的传输方向和/或强度。
例如，在该车灯***中，车灯设置在车体前侧，并可以包括左侧区域、中间区域和右侧区域。例如，变向单元可以至少配置为使得车灯的左侧区域或右侧区域的发射光线分别射向车体的左前方或右前方；又例如，变向单元还可以配置为使得车灯的发射光线向车体的前侧下方倾斜；再例如，变向单元还可以配置为对中间区域的发射光线进行准直，以使中间区域的发射光线射向车体的正前方。例如，光强调节单元可以实现为车灯的驱动装置；又例如，光强调节单元还可以实现为光阻墙面。例如，第一控制单元可以配置为通过控制变向单元和/或光强调节单元(例如，车灯的驱动装置)来控制车灯的发射光线的出射方向和/或亮度，由此可以提升驾驶安全性。
例如，车灯、变向单元和光强调节单元的类型、设置方式和调节方式可以根据实际应用需求设置，本公开的实施例对此不做具体限定。例如，车灯可以是荧光灯、钠灯、疝气灯等，也可以包括阵列排列的发光单元。例如，发光单元可以是有机发光二级管或无机发光二级管(例如，LED或微LED)。下面以车灯为阵列排列的发光单元为例详述本公开的再一个实施例，但本公开的实施例不限于此。
例如，图2是本公开至少一个实施例提供的一种车灯***300的示例性结构图，图2所示的车灯***为从车体上方观察的平面图，图2所示的行方向代表车体的左右方向，图2下部所示的在行方向上排列的小矩形框代表发光单元。该车灯***300包括车灯310、变向单元320和第一控制单元(图2中未示出)。
例如，如图2所示，车灯310可以包括第一车灯316和第二车灯317。例如，第一车灯316可以设置在车体的左前侧，并包括左侧区域311和第一中间区域314；第二车灯317可以设置在车体的右前侧，并包括右侧区域313和第二中间区域315；中间区域312可以包括第一中间区域314和第二中间区域315。例如，左侧区域311和右侧区域313分别占第一车灯316和第二车灯317发光面积的比例可以小于30％(例如，可以为20％)，但本公开的实施例不限于此。
例如，如图2所示，变向单元320可以包括第一变向单元321和第二变向单元322。例如，第一变向单元321可以设置在第一车灯316的出光侧，并至少配置为改变第一车灯316的左侧区域311的发射光线的出射方向，以使得左侧区域311的发射光线射向车体的左前方或右前方；第二变向单元322可以设置在第二车灯317的出光侧，并至少配置为改变第二车灯317的右侧区域313的发射光线的出射方向，以使得右侧区域313的发射光线射向车体的右前方或左前方。例如，变向单元320可以是光栅。又例如，第一变向单元321和第二变向单元322可以是反光镜，但本公开的实施例不限于此。下面以第一变向单元321和第二变向单元322是反光镜为例详述本公开的再一个实施例提供的一种车灯***300。
例如，可以在第一车灯316的左侧区域311和第二车灯317的右侧区域313的出光侧分别设置至少一个第一变向单元321和至少一个第二变向单元322。例如，可以将设置在左侧区域311出光侧的第一变向单元321的靠近所对应发光单元的一侧、在行方向上设置在所对应的发光单元的右侧，可以将设置在右侧区域313出光侧的第二变向单元322的靠近所对应发光单元的一侧、在行方向上(也即是车体的左右方向)设置在所对应的发光单元的左侧。因此，可以通过将设置在左侧区域311出光侧的第一变向单元321向车体左侧倾斜，使得左侧区域311的发射光线射向车体的左前方；可以通过将设置在右侧区域313出光侧的第二变向单元322向车体右侧倾斜，使得右侧区域313的发射光线射向车体的右前方，由此可以更好的观察会车车辆。或者可以将设置在左侧区域311出光侧的第一变向单元321向车体右侧倾斜，使得左侧区域311的发射光线射向车体的右前方；可以通过将设置在右侧区域313出光侧的第二变向单元322向车体左侧倾斜，使得右侧区域313的发射光线射向车体的左前方，由此可以避免对会车车辆的影响。一般情况下，由于左侧区域311和右侧区域313占第一车灯316和第二车灯317发光面积的比例较小，左侧区域311向车体左侧倾斜的光线以及右侧区域313向车体右侧倾斜的光线不足以对会车车辆造成影响。
例如，还可以在第一车灯316的第一中间区域314和第二车灯317的第二中间区域315的出光侧分别设置至少一个第一变向单元321和至少一个第二变向单元322。例如，可以将设置在第一中间区域314出光侧的第一变向单元321的靠近所对应发光单元的一侧、在行方向上设置在所对应的发光单元 的左侧，可以将设置在第二中间区域315出光侧的第二变向单元322的靠近所对应发光单元的一侧、在行方向上设置在所对应的发光单元的右侧。由此，可以通过将设置在第一中间区域314出光侧的第一变向单元321向右倾斜，使得第一中间区域314的发射光线射向车体的右前方；可以通过将设置在第二中间区域315出光侧的第二变向单元322向左倾斜，使得第二中间区域315的发射光线射向车体的左前方。例如，第一中间区域314的发射光线向车体的右前侧倾斜的角度以及第二中间区域315的发射光线向车体的左前侧倾斜的角度可以均小于2度。由此可以使得驾驶人员能够更好的观察车体正前方的道路。显然，第一中间区域314和第二中间区域315还可以不设置第一变向单元321和第二变向单元322，此时可以使得第一中间区域314和第二中间区域315的发光单元的出射光线以一定的发散角射向车体的前方。
例如，如图2所示，可以针对第一车灯316和第二车灯317的每两个发光单元设置一个第一变向单元321和一个第二变向单元322。显然，第一变向单元321和第二变向单元322的设置密度不限于此。例如，可以针对第一车灯316和第二车灯317的每个发光单元分别设置一个第一变向单元321和一个第二变向单元322。又例如，还可以针对第一车灯316和第二车灯317的每三个发光单元分别设置一个第一变向单元321和一个第二变向单元322。再例如，可以针对第一车灯316的左侧区域311和第二车灯317右侧区域313的每个发光单元设置一个第一变向单元321和一个第二变向单元322，针对第一车灯316的第一中间区域314和第二车灯317中间区域312的每三个发光单元设置一个第一变向单元321和一个第二变向单元322。
例如，第一控制单元可以配置通过控制变向单元和/或车灯来控制车灯的发射光线的出射方向和/或亮度。例如，该第一控制单元可以为中央处理器(例如X86处理器、ARM处理器)、可编程逻辑控制器(PLC)、数字信号处理器(DSP)等。
例如，本公开至少一个实施例提供的一种车灯***通过变向单元使得左侧区域和右侧区域的出射光线分别射向车体的左前侧和右前侧，进而使得驾驶人员可以在不影响会车车辆的前提下更好的观察会车车辆。此外，还可以通过变向单元使得第一中间区域和第二中间区域的出射光线射向车体的前方，或者分别向车体右侧/左侧略微倾斜，使得驾驶人员能够更好的观察车体正前方的道路。由此，配备本公开至少一个实施例提供的一种车灯***的车 辆的驾驶安全性得到了提升。
例如，图3是本公开至少一个实施例提供的另一种车灯***300的示例性结构图，图3所示的车灯***为从车体上方观察的平面图，图3所示的行方向代表车体的左右方向，图3下部所示的在行方向上排列的小矩形框代表发光单元。该车灯***300包括车灯310、变向单元320和第一控制单元(图2中未示出)。
例如，如图3所示，车灯310可以包括前侧车灯318。前侧车灯318可以设置在车体的前侧中间区域，并包括左侧区域311、中间区域312和右侧区域313。例如，左侧区域311和右侧区域313占前侧车灯318发光面积的比例可以均为10％，但本公开的实施例不限于此。
例如，如图3所示，变向单元320可以设置在左侧区域311和右侧区域313的出光侧，并至少配置为改变左侧区域311和右侧区域313的发射光线的出射方向，以使得左侧区域311和右侧区域313的发射光线分别射向车体的左前方和右前方。例如，变向单元320的设置密度可以根据实际应用需求进行设定，本公开的实施例对此不做具体限定。
例如，可以在左侧区域311和右侧区域313的出光侧分别设置至少一个变向单元320。例如，可以将设置在左侧区域311出光侧的变向单元320的靠近所对应发光单元的一侧、在行方向上设置在所对应的发光单元的右侧，可以将设置在右侧区域313出光侧的变向单元320的靠近所对应发光单元的一侧、在行方向上设置在所对应的发光单元的左侧。从而，可以通过将设置在左侧区域311出光侧的变向单元320向车体左侧倾斜，使得左侧区域311的发射光线射向车体的左前方；可以通过将设置在右侧区域313出光侧的变向单元320向车体右侧倾斜，使得右侧区域313的发射光线射向车体的右前方。由此可以在不影响会车车辆的情况下更好的观察会车车辆。
例如，根据实际应用需求，还可以在中间区域312的出光侧设置变向单元320，以控制设置在中间区域312发光单元的所发射光线的出射方向。由此可以使得驾驶人员更好的观察前方道路。
例如，第一控制单元可以配置通过控制变向单元和/或车灯来控制车灯的发射光线的出射方向和/或亮度。例如，该第一控制单元可以为中央处理器(例如X86处理器、ARM处理器)、可编程逻辑控制器(PLC)、数字信号处理器(DSP)等。
例如，本公开至少一个实施例提供的另一种车灯***通过变向单元使得左侧区域和右侧区域的出射光线分别射向车体的左前侧和右前侧，使得驾驶人员可以在不影响会车车辆的情况下更好的观察会车车辆。此外，还可以通过变向单元控制设置在中间区域发光单元的所发射光线的出射方向，使得驾驶人员更好的观察前方道路。由此配备本公开至少一个实施例提供的另一种车灯***的车辆的驾驶安全性得到了提升。
例如，图4是本公开至少一个实施例提供的再一种车灯***300的示例性结构图，图4所示的车灯***为从车体上方观察的平面图，图4所示的行方向代表车体的左右方向，图4下部所示的在行方向上排列的小矩形框代表发光单元。该车灯***300包括车灯310、变向单元320和第一控制单元(图2中未示出)。
例如，如图4(a)所示，变向单元320可以包括透镜，例如，变向单元320可以是由阵列排列的透镜组成的透镜阵列323。例如，透镜阵列323的具体形式可以根据实际应用需求进行设定，本申请的实施例对此不做具体限定。例如，如图4(a)所示，透镜阵列323可以设置在中间区域312的出光侧，例如，透镜阵列323的每个透镜单元可以分别对应于阵列分布的发光单元中的其中一个发光单元。例如，发光单元可以设置在透镜阵列323的焦点上。例如，透镜阵列323可以配置为对中间区域312的发射光线进行准直，以使中间区域312的发射光线射向车体的正前方，由此可以使得驾驶人员更好的观察车体正前方的道路。
例如，车灯***300还可以包括扩散模块324。例如，扩散模块324可以设置在左侧区域311和右侧区域313的出光侧，并配置为增加左侧区域311和右侧区域313的发射光线的发散角。例如，扩散模块324可以包括分别设置左侧区域311和右侧区域313的透镜阵列，并且左侧区域311和右侧区域313发光单元设置在所对应透镜阵列焦点的靠近透镜阵列的一侧，由此设置在左侧区域311和右侧区域313出光侧的透镜阵列可以扩大左侧区域311和右侧区域313出射光线的发散角，进而可以使得驾驶人员在不影响会车车辆的前提下更好的观察会车车辆。
例如，车灯的亮度等级可以通过控制被点亮的灯的数量等方式进行控制。又例如，车灯的亮度等级还可以通过控制驱动车灯的驱动电流大小的方式进行控制，由此可以调节车灯的出射光线的强度。
例如，上述变向单元320还可以为液晶透镜阵列500，如图4(b)所示，该液晶透镜阵列500包括彼此对置的第一基板511和第二基板512以及二者之间的液晶层530。对于每个液晶透镜单元510，第一基板511上例如设置有面状电极521，第二基板512上例如设置有条状电极522，这些条状电极522至少部分可以被施加不同的电压由此可以驱动液晶分子具有不同的偏转程度从而得到具有不同屈光度的透镜单元。
显然，本申请实施例提供变向单元320不限于由阵列排列的透镜组成的透镜阵列。例如，图4(c)所示，在车灯310为荧光灯、钠灯、疝气灯等的情况下，还可以通过设置一个单一透镜550(例如，双凸透镜)对车灯中间区域的发射光线进行准直，以使中间区域的发射光线射向车体的正前方。
例如，第一控制单元可以配置通过控制变向单元和/或车灯来控制车灯的发射光线的出射方向和/或亮度。例如，该第一控制单元可以为中央处理器(例如X86处理器、ARM处理器)、可编程逻辑控制器(PLC)、数字信号处理器(DSP)等。
例如，本公开至少一个实施例提供的再一种车灯***通过变向单元使中间区域的发射光线射向车体的正前方，由此可以使得驾驶人员更好的观察车体正前方的道路。此外，还可以通过设置在左侧区域和右侧区域的扩散模块扩大左侧区域和右侧区域出射光线的发散角，由此可以使得驾驶人员在不影响会车车辆的前提下更好的观察会车车辆。由此，配备本公开至少一个实施例提供的再一种车灯***的车辆的驾驶安全性得到了提升。
例如，对于图2、图3、图4(a)-图4(c)所示的车灯***300，变向单元320还可以配置为使得车灯310的发射光线向车体的前侧下方倾斜。例如，对于图2和图3所示的车灯***300，可以通过使得对应的反光镜(例如，反光镜的反光面)向车体下侧倾斜，使得车灯310的出射光线向车体下侧倾斜。由此，可以在会车时减少灯光对会车车辆的影响，可以对远近光(例如，车灯出射的光线的照射或传输的距离)进行调控。
例如，变向单元320和/或车灯310的出射光线的调节方式可以根据实际应用需求进行选择，本公开的实施例对此不做具体限定。例如，驾驶人员可以基于对会车车辆距离的判断，向变向单元320和/或车灯310的调节机构发送调节指令来调节变向单元320和/或车灯310出射光线。又例如，为了进一步提高驾驶安全性，本公开至少一个实施例提供的车灯***300可以包括图 像采集单元(例如CCD或CMOS摄像头)和处理单元(例如数字信号处理器等)。例如，图像采集单元可以设置于车体前侧，并配置为采集车体前方的、与车体运动方向相反的其它车辆的图像。例如，处理单元可以根据图像采集单元所获取的图像确定车体前方的、与车体运动方向相反的其它车辆与车体之间的距离。例如，可以在车体前侧设置两个图像采集单元，两个图像采集单元可以在同一时刻拍摄会车车辆的两张照片，处理单元可以基于所述两张照片和双目立体视觉测距技术确定在拍摄两张图片时刻的与会车车辆的车距，因此处理单元可以根据距离控制变向单元320并调节车灯310的出光方向，由此可以实现车灯310出射方向的自动调节，并由此可以进一步提升驾驶安全性。此外，处理单元还可以根据距离控制所述光强调节单元(例如，光强调节单元可以是控制车灯发光光强的驱动电路)，以调节所述车灯的出光强度。
例如，图11(a)是本公开至少一个实施例提供的再一种车灯***600的一种示例性结构图。例如，该车灯***600可以包括车灯601和阵列排列的光阻墙面602(也即，光强调节单元)，光阻墙面602设置在车灯601的出光侧。由图11(a)可以明显的看到光阻墙面可以阻挡部分车灯601的发射光线，由此可以调节车灯***600出射光线的强度，并因此可以提升驾驶安全性。
例如，车灯601不限于图11(a)所示的点光源，还可以为例如图11(b)所示的阵列排列的发光单元603。例如，还可以通过控制两个相邻的光阻墙面602之间的间距，来调节车灯***600出射光线的强度。例如，可以通过降低两个相邻的光阻墙面602之间的间距来降低车灯***600出射光线的强度。
例如，光阻墙面602的设置方式不限于图11(a)所示的任意两个相邻的光阻墙面602之间的间距均相等的方式，例如，两个相邻的光阻墙面602之间的间距还可以设置为不相等的形式。
例如，在车灯601设置在车体正前方的情况下，可以将光阻墙面602设置为如图11(c)所示的形式，也即是对应于车灯601左右两侧区域的光阻墙面602之间的间距小于对应于车灯601中间区域的光阻墙面602之间的间距，由此可以降低车灯***600的出射光线对车体两侧会车车辆的影响，并因此可以提升驾驶安全性。
又例如，在车灯601包括设置在车体前方左侧和前方右侧的左侧车灯604和右侧车灯605的情况下，可以将光阻墙面602设置为如图11(d)所示的形 式，也即是对应于左侧车灯604左侧区域的光阻墙面602之间的间距小于对应于左侧车灯604中间区域和右侧区域的光阻墙面602之间的间距，且对应于右侧车灯605右侧区域的光阻墙面602之间的间距小于对应于右侧车灯605中间区域和左侧区域的光阻墙面602之间的间距，由此可以降低车灯***600的出射光线对车体两侧会车车辆的影响，并因此可以提升驾驶安全性。

例如，车灯通信***350可以包括信号发送模块351和信号接收模块353；信号发送模块351可以包括调制模块352，调制模块352可以配置为对车灯310进行调制，以将信息加载在车灯所发射的至少部分光线上；信号接收模块353可以包括光电探测模块354和解调模块355，光电探测模块354可以配置为探测入射到其上的可见光光强，解调模块355可以配置为获取加载在光电探测模块354所探测光线上的信息。例如，调制模块352、光电探测模块354和解调模块355的设置方式可以参见现有的可见光通信***，例如可通过相应的电路实现，在此不再赘述。
例如，图5(b)示出了图5(a)示出的车灯通信***的示例性应用场景。例如，如图5(b)所示，在主车车辆引起会车车辆驾驶人员眼睛不舒适的情况下，可以执行如下的步骤：
1、会车车辆驾驶人员可以发送车灯调节请求指令；

8、主车车辆调整车灯，例如，可以由主车车辆的驾驶人员调整车灯，或者由主车车辆自动调整。例如，可以调整车灯至少部分出射光线的出射方向或/和车灯的发光亮度。
例如，本公开至少一个实施例提供的车灯通信***的可以使得会车车辆驾驶人员在感到对方车灯耀眼时，向对方车辆发送车灯调节请求，由此可以进一步地提升配备了本公开至少一个实施例提供的车灯通信***的车辆驾驶安全性。
本公开的至少一个实施例提供的车载***还可以包括调光***。例如，该调光***包括第一光电传感模块和透明显示面板。例如，根据实际应用需求，该调光***还可以包括第二控制单元。例如，该调光***可以独立用于交通工具或可以与上述车灯***组合使用。
例如，在该调光***中，第一光电传感模块设置于后车窗上并配置为探测入射到第一光电传感模块的可见光的光强。例如，第二控制单元配置为基于第一光电传感模块探测到的可见光的光强控制透明显示面板220的透过率。例如，透明显示面板至少设置于后车窗的部分区域，透过率在第二控制单元的控制下可以发生改变；例如，在第一光电传感模块探测到的可见光的光强大于光强阈值时，第二控制单元可以配置为降低透明显示面板的透过率；又例如，在第一光电传感模块探测到的可见光的光强小于光强阈值时，第二控制单元还可以配置为提升透明显示面板的透过率。
例如，图1(a)是本公开至少一个实施例提供的一种调光***200的侧视图。例如，如图1(a)所示，该调光***200可以包括第一光电传感模块211、透明显示面板220和第二控制单元(图中未示出)。
例如，第一光电传感模块211可以设置在后车窗230上，并配置为探测入射到后车窗230上的可见光的光强。例如，透明显示面板220可以设置在后车窗230上，并配置为在第一光电传感模块211探测到的可见光的光强大于光强阈值时，降低透明显示面板220的透过率。因此，本公开一个实施例提供的一种调光***200可以在入射到后车窗230上的可见光的光强过强时，降低进入车体内部241光线的强度，以及反射到车内驾驶人员的眼睛中的光强，由此可以提高驾驶安全性。
例如，透明显示面板220的类型和设置方式可以根据实际应用需求进行 设定，本公开的实施例对此不做具体限定。例如，透明显示面板220可以包括液晶显示面板、OLED显示面板、电致变色显示面板的至少一种。
例如，如图1(a)所示，透明显示面板220可以设置于后车窗230的至少部分区域，例如，透明显示面板220的设置位置可以对应于设置车内后视镜的位置处，由此可以进一步的降低反射到车内驾驶人员的眼睛中的光强，以及进一步的提升驾驶安全性。又例如，如图1(b)所示，透明显示面板220还可以设置于后车窗230的整个区域或者可以使用透明显示面板220作为后车窗。
例如，第一光电传感模块211的设置位置可以根据实际应用需求进行设定，本公开的实施例对此不做具体限定。例如，如图1(a)所示，第一光电传感模块211可以设置于后车窗230的远离车体内部241的一侧。又例如，第一光电传感模块211还可以设置于后车窗230的靠近车体内部241的一侧。
例如，光强阈值可以根据实际应用需求进行设定，本公开的实施例对此不做具体限定。例如，可以通过测试确定使得驾驶人员眼睛舒适的光强值作为光强阈值。又例如，还可以根据人眼舒适的光强值的经验值设置光强阈值。
例如，在第一光电传感模块211探测到的可见光的光强大于光强阈值的情况下，透明显示面板220的透过率的降低方式以及降低量值可以根据实际应用需求进行设定，本公开的实施例对此不做具体限定。
例如，在第一光电传感模块211设置在后车窗230的远离车体内部241的一侧的情况下，可以基于预先设定的使得驾驶人员眼睛舒适的光强值与第一光电传感模块211所探测到的光强的比值确定透明显示面板220的透射率需要降低的量值，此时可以快速地调节透明显示面板220的透射率。又例如，在第一光电传感模块211设置在后车窗230的靠近车体内部241的一侧的情况下，可以基于第一光电传感模块211所探测的光强数值是否大于预先设定的使得驾驶人员眼睛舒适的光强值确定透明显示面板220的透射率是否需要继续调低，由于第一光电传感模块211所探测的光强为车体内部241的光强，上述设置方式可以使得车内的光强更接近于使得驾驶人员眼睛舒适的光强值。
例如，第二控制单元可以配置为基于第一光电传感模块探测到的可见光的光强控制透明显示面板的透过率。例如，该第二控制单元可以为中央处理器(例如X86处理器、ARM处理器)、可编程逻辑控制器(PLC)、数字信号 处理器(DSP)等。
例如，为了更加精细的调节车内反射部件反射到驾驶人员眼睛中的光强，调光***200还可以包括第二光电传感模块212，该第二光电传感模块212可以设置于后车窗230的靠近车体内部241的一侧，并配置为探测通过后车窗230的可见光的光强。此时，第一光电传感模块211设置于后车窗230的远离车体内部241的一侧，并配置为探测照射到后车窗230上的可见光的光强。
例如，透明显示面板220可以根据第一光电传感模块211所探测到的信号强度与第二光电传感模块212所探测到的信号强度确定透明显示面板220的透过率。例如，首先可以基于预先设定的使得驾驶人员眼睛舒适的光强值与第一光电传感模块211所探测到的光强的比值确定透明显示面板220的透射率需要降低的量值，并使得车体内部241的光强快速降低；然后可以基于第二光电传感模块212所探测到的信号强度与使得驾驶人员眼睛舒适的光强值，更加精细的调节透明显示面板220的透射率，以使车内的光强更接近于使得驾驶人员眼睛舒适的光强值。
又例如，透明显示面板220的透过率还可以基于第一光电传感模块211所探测到的光强L1与第二光电传感模块212所探测到的光强L2的差值的绝对值进行调节。例如，可以在|L2-L1|>＝M0的情况下调节透明显示面板220的透过率，以在调节透明显示面板220之后使得|L2-L1|<M0，其中，光强超过M0时，人眼会明显感到不舒适。例如，在|L2-L1|>＝M0的情况下，使透明显示面板220的透过率降低x％，调整后的光强Lx＝L2(1-x％)，为使得光强满足|Lx-L1|<M0，也即L2(1-x％)-L1<M0，x需满足如下的条件：x％>(L2-(L1+M0))/L2，也即是需要将车窗的透过率自动降低不小于(L2-(L1+M0))/L2，由此可以使得驾驶人员不会产生眩晕感。
例如，透明显示面板220还可以配置为显示图像、文字和符号信息的至少一种。例如，透明显示面板220可以在车辆变道前或减速前显示文字或符号信息(例如“新手上路”)，以提醒后方车辆注意车距，由此可以进一步的提升驾驶安全性。
例如，本公开一个实施例提供的一种车载***可以通过降低调光***的透过率减少反射到车内驾驶人员的眼睛中的光强和/或显示安全提示信息来提高驾驶安全性。
例如，根据实际应用需求，本公开的至少一个实施例提供的车载***还可以包括显示***。例如，显示***包括图像采集装置、图像显示装置和反射结构。例如，根据实际应用需求，该显示***还可以包括第三控制单元。该显示***可以独立用于交通工具或可以与上述调光***或/和车灯***组合使用。
例如，在显示***中，图像采集装置包括第一图像采集装置、第二图像采集装置和第三图像采集装置，第一图像采集装置、第二图像采集装置和第三图像采集装置分别配置为采集车体的左后侧、正后侧和右后侧的图像；图像显示装置设置在车内后视镜位置处，包括第一图像显示区域、第二图像显示区域和第三图像显示区域，第一图像显示区域、第二图像显示区域和第三图像显示区域分别配置为显示第一图像采集装置、第二图像采集装置和第三图像采集装置所采集的车体的左后侧、正后侧和右后侧的图像；反射结构设置在第二图像显示区域的至少部分区域中，并配置为至少部分反射入射到至少部分区域上的可见光；第三控制单元配置为在收到第二图像显示区域启动信号后使得第二图像采集装置和第二图像显示区域处于工作状态。
例如，图6是本公开至少一个实施例提供的显示***100的示例性结构图。例如，如图6所示，该车载***10包括显示***100，该显示***100包括图像采集装置110、图像显示装置120、反射结构130和第三控制单元140。
例如，该图像采集装置110可以包括第一图像采集装置111、第二图像采集装置112和第三图像采集装置113。例如，图像采集装置110的类型可以根据实际应用需求进行设定，本公开的实施例对此不做具体限定。例如，图像采集装置110可以为CCD型或CMOS型摄像头等，可以为可见光摄像头，也可以包括红外光摄像头等。
例如，图像采集装置110的具***置可以根据实际应用需求进行设定，本公开的实施例对此不做具体限定。例如，图7(a)和图7(b)示出了图像采集装置110的一种设置方式，图7(a)和图7(b)分别示出了配备本公开至少一个实施例提供的显示***100的车辆的示例性正视图和左视图。
例如，如图7(a)和图7(b)所示，第一图像采集装置111可以设置于车体左侧的原左侧后视镜所处的位置处，第二图像采集装置112可以设置于车体正后侧，第三图像采集装置113设置于车体右侧的原右侧后视镜所处的位置处，由此第一图像采集装置111、第二图像采集装置112和第三图像采集 装置113可以分别采集车体的左后侧、正后侧和右后侧的图像。例如，由于第一图像采集装置111和第三图像采集装置113可以实现现有车体左侧后视镜和右侧后视镜的功能，因此设置了本公开实施例提供的显示***100的车体可以无需设置左侧后视镜和右侧后视镜。
例如，本公开实施例的图像采集装置110的设置方式不限于图7(a)和图7(b)所示的情形。例如，根据实际应用需求，第一图像采集装置111还可以设置于车体左侧的原左侧后视镜所处的位置的靠近车体前部的一侧，第三图像采集装置113还可以设置于车体右侧的原右侧后视镜所处的位置处的靠近车体前部的一侧。
例如，根据实际应用需求，图像采集装置110还可以包括第四图像采集装置和第五图像采集装置，第四图像采集装置和第五图像采集装置可以分布设置在车体左侧和右侧的中部区域，由此可以增加图像采集装置110采集图像的范围，进而可以提升驾驶安全性。
例如，根据实际应用需求，图像采集装置110还可以包括具有角度调节(例如左右调节或/和上下调节)能力的部件(例如云台等)，由此可以增加图像采集装置110采集图像的范围，进而可以提升驾驶安全性。
例如，图像显示装置120可以设置在车内后视镜位置处，并包括第一图像显示区域121、第二图像显示区域122和第三图像显示区域123。第一图像显示区域121、第二图像显示区域122和第三图像显示区域123可以分别配置为显示第一图像采集装置111、第二图像采集装置112和第三图像采集装置113所采集的车体的左后侧、正后侧和右后侧的图像。
例如，通过将左侧后视镜和右侧后视镜的功能集成在设置在车内后视镜位置处的图像显示装置120上，使得汽车驾驶人员仅需观察设置在一个位置处的图像显示装置120，便可以获得车体周边环境的信息。由此可以避免分散驾驶人员的注意力，进而可以提升驾驶安全性。
例如，图像显示装置120的第一图像显示区域121、第二图像显示区域122和第三图像显示区域123的具体设置方式可以根据实际应用需求进行设定，本公开的实施例对此不做具体限定。例如，图8(a)和图8(b)分别示出了本公开至少一个实施例提供的显示***100的图像显示装置120的一种结构的平面示意图和剖面示意图，图8(b)示出的剖面示意图是沿图8(a)所示的A-A’线剖切得到。
例如，如图8(a)和图8(b)所示，第一图像显示区域121、第二图像显示区域122和第三图像显示区域123可以由左到右顺次设置。显然，本公开的实施例不限于此。
例如，在图像采集装置110还包括第四图像采集装置和第五图像采集装置的情况下，图像显示装置120还可以包括第四图像显示区域和第五图像显示区域。例如，第四图像显示区域和第五图像显示区域可以分别设置在第一图像显示区域121的左侧和第三图像显示区域123右侧，显然，本公开的实施例不限于此。
例如，第一图像显示区域121、第二图像显示区域122和第三图像显示区域123可以分别对应一块显示屏。又例如，第一图像显示区域121、第二图像显示区域122和第三图像显示区域123可以对应同一块显示屏。再例如，第一图像显示区域121和第三图像显示区域123可以对应于同一块显示屏，第二图像显示区域122可以对应于一块显示屏，本公开的实施例对此不做具体限定。
例如，可以根据实际应用需求选择图像显示装置120的显示屏的类型，本公开的实施例对此不做具体限定。例如，图像显示装置120的显示屏可以是LCD(液晶显示器件，Liquid Crystal Display)、OLED(有机发光显示器件，Organic Light Emitting Display)、PDP(等离子显示面板，Plasma Display Panel)、LED(发光二极管显示器件，Light Emitting Diode Display)和EPD(电泳显示面板，Electrophoretic Display Panel)中的至少一种。例如，图像显示装置120的显示屏的形状可以是图7(a)所示的矩形，或者是椭圆形、圆形等异形。例如，图像显示装置120的显示屏可以是不可弯曲的硬质显示屏或者可以弯曲的柔性显示屏。
例如，该显示***100还可以包括反射结构130，该反射结构130可以设置在第二图像显示区域122的至少部分区域中，并配置为至少部分反射入射到至少部分区域上的可见光。例如，反射结构130的具体设置方式可根据实际应用需求进行设定，本公开的实施例对此不做具体限定。
例如，图9(a)和图9(b)分别示出了本公开至少一个实施例提供的显示***100的图像显示装置120的一种反射结构130的平面示意图和剖面示意图，图9(b)示出的剖面示意图是沿图9(a)所示的A-A’线剖切得到。
例如，如图9(a)和图9(b)所示，反射结构130可以覆盖第二图像显 示区域122的全部区域，反射结构130包括部分反射部分透射器件。此处，第二图像显示区域122发射的部分光线可以透过部分反射部分透射器件并传递到驾驶人员的眼睛中，部分入射到部分反射部分透射器件的车体后侧的环境光线可以通过部分反射部分透射器件的反射传递到驾驶人员的眼睛中。因此，驾驶人员在车外可视度较高(例如，天气晴朗的白天)的情况下，可以选择使用部分反射部分透射器件反射的光线观察车体后侧的环境；而在车外可视度较低(例如，雨雪天或夜晚)的情况下，可以选择启用第二图像采集装置112和图像显示装置120的第二图像显示区域122，以更好的观察车体后侧的环境。由此本公开再一个实施例提供的显示***100可以在保证驾驶安全性的同时节省图像显示装置120的功耗。
例如，可以根据实际应用需求选择部分反射部分透射器件的类型以及部分反射部分透射器件对可见光的反射率。例如，部分反射部分透射器件可以包括多层膜复合结构、不连续铝蒸镀膜、不连续锡蒸镀膜、液晶膜材中至少一种。例如，部分反射部分透射器件对可见光的反射率可以为30％-70％。例如，部分反射部分透射器件对可见光的反射率可以为40％、50％或60％。
例如，图10(a)和图10(b)分别示出了本公开至少一个实施例提供的显示***100的图像显示装置120的另一种反射结构130的平面示意图和剖面示意图，图10(b)示出的剖面示意图是沿图10(a)所示的B-B’线剖切得到。例如，如图10(a)和图10(b)所示，反射结构130可以覆盖第二图像显示区域122的部分区域(例如，第二图像显示区域122的上部)。例如，反射结构130可以包括高反射器件。例如，高反射器件对可见光的反射率可以大于99％。例如，可以根据实际应用需求选择高反射器件的类型，例如，高反射器件可以包括银膜或铝膜等。
例如，通过将具有高反射率的反射结构130设置在第二图像显示区域122的部分区域上，反射结构130可以反射更多的车体后侧环境光线，由此在不启用图像显示装置120的第二图像显示区域122的情况下，可以更好地观察车体后侧的环境。例如，由于图像显示装置120的第二显示区域的部分区域未被反射结构130所覆盖，因此，更多的图像显示装置120的发射光线将被驾驶人员的眼睛所接收，由此不仅可以降低图像显示装置120的功耗，还可以使得驾驶人员可以更好的观察车体后侧的环境。例如，第二图像显示区域122可以仅在车外可视度较低(例如，雨雪天或夜晚)的情况下启用，由此可 以降低图像显示装置120的功耗。
例如，该显示***100还可以包括第三控制单元140，该第三控制单元140可以配置为在收到第二图像显示区域启动信号后使得第二图像采集装置112和第二图像显示区域122处于工作状态，由此可以降低图像显示装置120的功耗。例如，该第三控制单元可以为中央处理器(例如X86处理器、ARM处理器)、可编程逻辑控制器(PLC)、数字信号处理器(DSP)等。
例如，如图6所示，在本公开的一个实施例中，还可以包括信号驱动模块150，该信号驱动模块150包括第一信号驱动模块151、第二信号驱动模块152和第三信号驱动模块153。例如，第一图像采集装置111将采集到的车体的左后侧的图像传递给第一信号驱动模块151，第一信号驱动模块151驱动图像显示装置120的第一图像显示区域121显示车体的左后侧的图像；第三图像采集装置113将采集到的车体的右后侧的图像传递给第三信号驱动模块153，第三信号驱动模块153驱动图像显示装置120的第三图像显示区域123显示车体的右后侧的图像。信号驱动模块150(包括第一信号驱动模块151、第二信号驱动模块152和第三信号驱动模块153)可以通过硬件、软件、固件或它们的组合等方式实现，例如由通常的图像信号处理电路实现。
例如，在车外可视度较高(例如，天气晴朗的白天)的情况下，图像显示装置120的第二图像显示区域122处于待机状态，驾驶人员可以通过反射结构130观察车体后侧的环境。在车外可视度较低(例如，雨雪天或夜晚)的情况下，驾驶人员可以通过第三控制单元140启用第二图像采集装置112和图像显示装置120的第二图像显示区域122，第二图像采集装置112将采集到的车体的正后侧的图像传递给第二信号驱动模块152，第二信号驱动模块152驱动图像显示装置120的第二图像显示区域122显示车体的右后侧的图像。
例如，第一信号驱动模块151、第二信号驱动模块152和第三信号驱动模块153可以为三个独立的模块，每一个信号驱动模块150与对应的图像显示区域的信号接口相连接。又例如，第一信号驱动模块151、第二信号驱动模块152和第三信号驱动模块153的功能可以由一个集成的信号驱动模块150实现。例如，所述集成的信号驱动模块150可以实现对图像显示装置120的分区域控制，例如，所述集成的信号驱动模块150可以实现像素点对点的输入。又例如，所述集成的信号驱动模块150可以使得第一信号驱动模块151、第二 信号驱动模块152和第三信号驱动模块153接收到的信号分别仅传递给第一显示区域、第二显示区域和第三显示区域。例如，本公开再一个实施例提供的车载***通过将左侧后视镜和右侧后视镜的功能集成在设置在车内后视镜位置处的图像显示装置上，使得汽车驾驶人员仅需观察设置在一个位置处的图像显示装置，便可以获得车体周边环境的信息。由此可以避免分散驾驶人员的注意力，进而可以提升驾驶安全性。本公开再一个实施例提供的车载***可与上述调光***配合使用，进一步提升驾驶安全性。
本公开另一实施例提供了一种交通工具，该交通工具包括上述车载***。该交通工具可以为多种类型，例如可以为轿车、客车或货车等。
本公开的实施例提供了一种车载***和交通工具，该车载***可以应用于交通工具的驾驶中，并可以提高了交通工具驾驶的安全性。
虽然上文中已经用一般性说明及具体实施方式，对本公开作了详尽的描述，但在本公开实施例基础上，可以对之作一些修改或改进，这对本领域技术人员而言是显而易见的。因此，在不偏离本公开精神的基础上所做的这些修改或改进，均属于本公开要求保护的范围。
