背景技术
本部分提供了与本公开有关的背景信息,但是这些信息并不必然构成现有技术。
当车辆在光线较暗的道路上行驶时,例如当在夜间行车时,车辆的驾驶员通常需要打开车辆的前照灯中的远光,以提供亮度较高、照射范围较远的照明区域,从而改善驾驶员对路面的可视性。然而,当道路上的车辆较多时,或者当在会车或跟车时没有及时地将远光切换为近光时,前照灯所发出的远光可能会照射到前方车辆的驾驶员,远光所产生的超大光晕会占据其他驾驶员视觉中很大一部分面积从而导致其眩目,甚至在极端情况下可能会使其瞬间致盲,从而对周围的行人和车辆造成极大的潜在危害。
在相关技术中,提供了一种能够在远光中产生暗区的无眩目照明功能的车辆。为此,相关技术的车辆配备有用于对车辆周围的环境进行捕获的相机,同时前照灯配备有与该相机相匹配的控制***。在车辆的行驶过程中,所述相机对道路上的车辆进行识别,并且当通过相机确定存在前方车辆时,前照灯的控制***基于从所述相机传递的检测信号而将前照灯的相应的LED控制成关闭。由此,能够在不引起前方车辆的驾驶员眩目的情况下为本车辆的驾驶员提供最大程度的照明。
本公开的发明人注意到相关技术的车辆还存在改进的空间。例如,在相关技术中,车辆的前照灯与相机是分开安装的,因此,在车辆组装完成后需要对前照灯与相机进行最终的组合调试。此外,还需要针对车辆开发相应的控制***并进行相应的道路测试,而这增加了产品的成本。另外,相机的使用本身也增加了产品自身的成本。

具体实施方式
用于车辆照明的前照灯通常采用卤素光源和LED光源。LED光源由于拥有小的发光面积和高的光电转换效率而在汽车照明领域得以广泛应用,逐渐成为车辆照明领域的主力军。通过采用LED光源技术,车辆的前照灯不仅能够提供近光功能和远光功能,而且还能够提供在远光中产生暗区的无眩目照明功能。
以下首先将参照图1来具体地描述车辆的无眩目照明功能。
参照图1,当车辆1在光线较暗的道路上行驶时,车辆1的驾驶员通常会打开前照灯中的远光以提供亮度较高、照射范围较远的照明区域。在这种情况下,当车辆1检测到前方 车辆时,车辆1的前照灯将会关闭照向前方车辆的远光。
如图1中所示,车辆1的前照灯可以包括10个子照明区域。当确定在子照明区域6、7、8(图中未标出,位于子照明区域5-9之间)中存在对向车辆1’时,车辆1将照向子照明区域6、7、8的照明关闭。以此方式,车辆1的前照灯将仅朝向除对向车辆1’以外的区域(在图1中为子照明区域1-5、9、10)发出远光光线,从而在不引起对向车辆1’的驾驶员眩目的情况下为车辆1的驾驶员提供最大程度的照明。因此,当具备无眩目照明功能的车辆1在光线较暗的道路上行驶时可一直开启远光,进而可以大幅提高行车的安全性。
应当指出的是,尽管在图1中示出是在车辆1与对向车辆1’会车时车辆1的前照灯进行无眩目照明。然而,可以设想无眩目照明功能的其他应用场景。例如,当车辆1正在跟随前方车辆时,车辆1的前照灯也可以提供在远光中产生暗区的无眩目照明功能。
接下来,将参照图2对根据相关技术的提供前述无眩目照明的车辆进行详细的描述。
参照图2,在相关技术中,车辆1的前照灯10中的每个前照灯可以包括多个LED,LED的数量与前照灯10能够实现的像素数目相同,每个LED分别对应于前照灯的一个像素,并且每个像素能够照亮一个特定角度的子照明区域。如图2中所示,前照灯可以包括15个像素LED,并且因而可以形成15个子照明区域。当确定在这15个子照明区域中的至少一个子照明区域中存在前方车辆时,车辆1可以将对所述至少一个子照明区域的照明关闭。
为了对前方车辆进行识别,如图2中所示,车辆1配备有用于对车辆1的周围环境进行捕获的相机20。在车辆1的行驶过程中,相机20配置成对道路上的物体的图像进行捕获,随后通过车载算法对所捕获的图像进行处理,进而识别所捕获的物体是否为车辆。当通过相机20所捕获的图像确定在车辆1的前照灯的至少一个子照明区域中存在前方车辆时,车辆1控制前照灯以将对应于所述至少一个子照明区域的至少一个LED关闭,由此实现了车辆1的无眩目照明功能。
本公开的发明人注意到相关技术的车辆还存在改进的空间。例如,如图2中所示,前照灯10与相机20是分开安装的。因此在车辆组装完成后需要对前照灯10与相机20进行最终的组合调试。此外,根据相关技术的车辆1,需要针对车辆1开发相应的控制***并且需要进行相应的道路测试,因而增加了产品的成本。另外,根据相关技术的车辆1必须使用与前照灯10分开安装的相机20来识别前方车辆,这本身也会增加产品的成本。
为此,本公开的发明人提出了一种能够在不使用相机的情况下实现无眩目照明功能的前照灯。这种前照灯能够有效地改善在相关技术中存在的相机与前照灯的匹配问题,并且由于避免了相机的使用,因而能够降低生产成本。
根据本公开的发明人所提出的前照灯,通过将用于对本车辆所行驶的道路上的前方车辆进行识别的识别***有效地融合到本车辆的前照灯中,本车辆的前照灯自身即具有前方 车辆识别功能,从而不仅能够实现无眩目照明功能,帮助本车辆在光线较暗的道路行驶,提升行车的安全性,而且还能够有效地降低无眩目照明技术的使用难度,改善甚至完全消除将前照灯安装在车辆上时所需要的后续校准,并且由于还避免了相机的使用,因而降低了生产成本,有助于无眩目照明技术在市场上的普及。
下面将参照附图借助于示例性实施方式对本公开进行详细描述。要注意的是,对本公开的以下详细描述仅仅是出于说明目的,而绝不是对本公开的限制。此外,在各个附图中采用相同的附图标记来表示相同的部件。
还需要说明的是,为了清楚起见,在说明书和附图中并未描述和示出实际的特定实施方式的所有特征,并且,为了避免不必要的细节模糊了本公开关注的技术方案,在附图和说明书中仅描述和示出了与本公开的技术方案密切相关的装置结构,而省略了与本公开的技术内容关系不大的且本领域技术人员已知的其他细节。
以下将参照图3至图7B对根据本公开的示例性实施方式的具有无眩目照明功能的用于车辆的前照灯进行描述。
参照图3至图7B,根据本公开的示例性实施方式,提供了一种用于车辆1的前照灯10,该前照灯10可以包括多个LED 101、多个光电传感器102和控制器。在实施方式中,每个LED能够独立地被打开及关闭,并且每个LED在被打开时能够照亮车辆1前方的相应一个子照明区域,如图3中所示。此外,前照灯10还可以包括多个光电传感器102,多个光电传感器102与多个LED以一一对应的方式相匹配。控制器可以接收来自所述光电传感器102的电信号。
应当指出的是,在本文中,当使用术语“A与B以一一对应的方式相匹配”时,应当被理解为每个A与一个且唯一一个B相匹配。例如,在此应当理解的是,每个光电传感器与一个且唯一一个LED相匹配。
如图3和图4中所示,前照灯10可以包括15个LED和15个光电传感器。然而,应当理解的是,LED和光电传感器的数量不受限制,只要能够将光电传感器与LED以一一对应的方式设置即可。例如,前照灯10也可以包括10个LED和10个光电传感器。
根据本公开的示例性实施方式,每个光电传感器可以被构造成检测与匹配的LED相应的子照明区域内的前方车辆1’发出的光,并且在检测到前方车辆1’发出的光时向控制器发送电信号。控制器可以配置成:响应于接收到的来自光电传感器的电信号而将与发送所述电信号的光电传感器相匹配的LED关闭。
根据本公开的示例性实施方式所提供的用于车辆的前照灯10,在该前照灯中设置有与多个LED以一一对应的方式设置的多个光电传感器,以对与匹配的LED相应的子照明区域内的前方车辆进行检测。以此方式,在车辆的前照灯的照明***中,既存在能够照亮相 应的子照明区域的像素LED,又存在能够检测在相应的子照明区域内的前方车辆发出的光的光电传感器。因此,能够将相应的LED、相应的子照明区域以及相应的光电传感器三者完全对应。以此方式,可以通过针对性地控制相应的LED的打开和关闭来防止相应的子照明区域内的前方车辆的驾驶员的眩目,从而以较低的成本和简单的结构实现了在远光中产生暗区的无眩目照明功能。
根据示例性实施方式,前照灯10可以包括具有导光面1031的导光构件103,导光面1031设置在导光构件103的第一端部处,并且光电传感器102和匹配的LED 101可以布置在导光构件103的不同于第一端部的另外的端部处,如图5A至图6C中所示。
再次向回参照图3和图4,当存在前方车辆1’时,前方车辆1’发出的光穿过导光面1031并经由导光构件103引导而到达光电传感器102,并且由LED 101发出的光经由导光构件103引导到达导光面1031并穿过导光面1031而照亮相应的子照明区域。以此方式,从LED发出的光与匹配的LED相应的子照明区域内的前方车辆1’发出的光将经由同一导光面1031通过相同的导光构件103来引导。根据光路可逆性原理,当光线沿反方向传播时,将总是沿着与正向传播的同一路径的反向传播。因此,当至少一个光电传感器102接收到从前方车辆1’发出的光时,可以确定发出光的前方车辆1’此时正处于与匹配的LED 101相应的子照明区域内。在这种情况下,控制器可以有针对性地控制相应LED关闭,从而在最少程度地影响本车辆的照明的情况下避免引起前方车辆1’的驾驶员的眩目。
在一些实施方式中,参照图5A和图5B,导光构件103的上述另外的端部可以为与设置有导光面1031的第一端部相反的一体式端部,并且每个光电传感器102和匹配的LED 101可以以彼此邻接的方式布置在导光构件103的该一体式端部处。在这种情况下,导光构件103可以被设置为具有一个导光通道的导光体,并且每个LED 101发出的光与到达匹配的光电传感器102的光可以经由同一导光通道进行传输,因此光电传感器102可以具有极高的感光效率。然而,可以理解的是,在这种情况下,导光构件103的该一体式端部可能会较厚,因此在光学设计上可能会存在一定的挑战,例如可能会在照明像素的光斑控制方面存在困难。
应当指出的是,以上所描述的导光构件103仅是示例性的。在不背离本公开的精神和范围的情况下,可以对导光构件103做出各种的改型和变型。以下将参照图6A至图6C对导光构件103的一些变型实施方式进行具体的描述。出于简要的目的,在对导光构件103的变型实施方式进行描述时,与前述实施方式相同的部分将不再赘述。
在一些实施方式中,参照图6A至图6C,导光构件103的上述另外的端部可以包括彼此分开的第二端部和第三端部,多个LED 101和多个光电传感器102可以分别布置在该第二端部和第三端部处,并且导光构件103可以包括初级光学元件1032和导光元件1033。 如图6A中所示,初级光学元件1032可以包括多个第一分支部10320,并且导光元件1033可以包括多个第二分支部10330。初级光学元件1032的多个第一分支部10320可以与布置在导光构件103的第二端部处的多个LED 101以一一对应的方式相匹配,并且导光元件1033的多个第二分支部10330可以与布置在导光构件103的第三端部处的多个光电传感器102以一一对应的方式相匹配,如图6B和图6C中所示。
参照图6A至图6C并结合之前的图3和图4,可以理解的是,每个LED 101发出的光可以经由相匹配的第一分支部10320被引导至导光面1031并穿过导光面1031而照亮相应的子照明区域,而前方车辆1’发出的光穿过导光面1031并经由第二分支部10330引导而到达匹配的光电传感器102。
在示例性实施方式中,初级光学元件1032可以采用聚光器或者针状导光构件来设计。可以理解的是,初级光学元件的设计本质上都是使用全反射原理的光波导将光线导向到具***置,即将各个LED发出的光经过初级光学元件发射到相应的子照明区域。通过设置与该初级光学元件共用同一导光面的导光元件,可以在该导光元件处打破初级光学元件的全反射条件,增加这种导光元件的设计能够有效的将从前方车辆发出的光引导至相应的光电传感器的位置。以此方式,照明***中可以同时存在照亮相应的子照明区域的像素LED以及检测在相应的子照明区域内的前方车辆发出的光的光电传感器。因此,能够将各个LED、相应的子照明区域以及相应的光电传感器三者完全对应。
在一些实施方式中,初级光学元件1032与导光元件1033所形成的夹角可以在0度至90度的范围内。例如,如图6B中所示,在一些可选的示例性实施方式中,初级光学元件1032与导光元件1033所形成的夹角可以小到接近0度,例如1度或2度。此外,在另一些可选的示例性实施方式中,如图6C中所示,导光元件1033可以沿与初级光学元件1032的延伸方向大致垂直的方向延伸。
应当指出的是,导光元件1033与初级光学元件1032的排布方向可以是任意的,只要能够确保导光元件将前方车辆发出的光穿过导光面1031并经由第二分支部10330引导而到达匹配的光电传感器102且确保每个LED 101发出的光经由相匹配的第一分支部10320被引导至导光面1031并穿过导光面1031而照亮相应的子照明区域即可。以此方式,可以增加导光构件103的设计灵活性,并且可以提高前照灯的紧凑性。
在一些实施方式中,LED 101与光电传感器102在时间轴上可以以预定的占空比交替地工作,如图7A和图7B中所示。换言之,通过调节LED 101与光电传感器102各自在时间轴上的占空比,可以使LED 101和光电传感器102不在同一时间工作。由于光速是极快的,因而LED 101所发出的光即使在极小的时间尺度下也能够完全离开前照灯10。因此,可以确保光电传感器102所接收到的光线完全是从外界收集到的光线,从而避免了LED 101 自身发出的光对光电传感器102的影响。以此方式,可以进一步提高无眩目照明功能的控制精确性。
根据示例性实施方式,每个光电传感器和匹配的LED在时间轴上分别以10%和90%的占空比交替地工作,如图7A和图7B中所示。具体地,参照图7B的左部部分,在0s至0.1s的时间段内,光电传感器处于工作状态,而LED处于非工作状态,此时光电传感器能够对前方车辆发出的光进行检测。而如图7B的右部部分所示,在0.1s至1s的时间段内,LED处于工作状态,而光电传感器处于非工作状态,此时LED朝向车辆的前方发光,从而照亮各个子照明区域。可以理解的是,以上所描述的光电传感器和匹配的LED各自的占空比以及具体的工作时间段仅是示例,本公开并不以任何方式对此进行限制。
再次向回参照图3至图6C,在一些实施方式中,前照灯10还可以包括透镜107,透镜107在从LED发出的光的传播方向上设置在导光面1031的下游,并且透镜107可以配置成将从至少一个LED发出的光折射到与所述至少一个LED相对应的子照明区域内。根据示例性实施方式,如图3和图4中所示,透镜107的中央部可以与多个LED的整个照明区域的中央部对准。通过设置具有特定折射率的透镜,可以将相应LED发出光折射到对应的子照明区域内。
在一些实施方式中,前照灯10还可以包括安装有多个LED 101的散热器108,如图3和图4中所示。通过设置散热器,可以及时地对LED工作时所产生的热进行耗散,从而有助于延长LED的寿命。根据示例性实施方式,散热器108可以包括多个散热片1080。以此方式,通过增加多个散热片,可以进一步改善散热的均匀性,从而进一步延长LED的寿命。
根据本公开的示例性实施方式,还提供了一种车辆1,该车辆包括上述前照灯10和用于向该前照灯10供给电力的电力源。可以理解的是,本公开所提供的车辆1至少能够实现以上关于前照灯10所描述的各种优点。
在本公开的上下文中,术语“上”、“下”、“远”和“近”等方位术语的使用仅仅出于便于描述的目的,而不应视为是限制性的。虽然已经参照示例性实施方式对本公开进行了描述,但是应当理解,本公开并不局限于文中详细描述和示出的具体实施方式。在不偏离本公开的权利要求书所限定的范围的情况下,本领域技术人员可以对示例性实施方式做出各种改变。
在以上对本公开的示例性实施方式的描述中所提及和/或示出的特征可以以相同或类似的方式结合到一个或更多个其他实施方式中,与其他实施方式中的特征相组合或替代其他实施方式中的相应特征。这些经组合或替代所获得的技术方案也应当被视为包括在本公开的保护范围内。
