Description

外部车辆通知信息系统和具有该系统的车辆
相关申请的交叉引用
本申请根据《美国法典》第35编第119(a)条要求2017年12月8日提交的韩国专利申请号10-2017-0168538的权益，其全部内容通过引用并入本文。
技术领域
本公开涉及外部车辆通知信息系统，更具体地，涉及能够通过外部车辆通知信息系统向另一车辆(例如，后方车辆)的驾驶员明确通知本车辆相关信息的车辆。
背景技术
车辆可以设置有外部显示器，该外部显示器能够向附近车辆的驾驶员(例如，前/后和左/右车辆)通知本车辆的驾驶状态，以便实现安全驾驶。
外部显示器的示例是转向信号向导和倒车向导。作为示例，转向信号向导以闪烁的方式通知本车辆的左/右转向或车道改变意图。倒车向导以照明方式通知本车辆的倒车意图。
因此，转向信号向导和倒车向导用作外部显示器，向附近车辆的驾驶员(特别是后方车辆的驾驶员)通知本车辆的驾驶状态和信息，从而有利于安全驾驶。
然而，在对于车辆信息的外部通知显示效率方面，转向信号向导和倒车向导具有以下限制。
首先是缺乏可视性，这是因为在白天转向信号向导和倒车向导很难通过灯泡的照明在外面工作。其次是外部通知信息的限制，这是因为转向信号向导和倒车向导各自只有单一的用途。最后是各种商业实施的局限性，这是因为一种类型的技术(例如转向信号向导和倒车向导)不能提供额外的外部通知信息。
因此，本公开的目的是提供一种外部车辆通知信息系统和具有该系统的车辆，能够向外界显示本车辆的驾驶状态和信息以通知附近车辆的驾驶员，从而实现安全驾驶，特别是通过投影视频技术来呈现外部显示信息，从而通过外部显示信息的多样化来实现优越的市场性，同时无论白天和黑夜都保持对附近车辆的高可视性。
背景技术中描述的内容是帮助理解本公开的背景，并且可能包括本公开所属领域的技术人员之前未知的内容。
发明内容
本公开的外部车辆通知信息系统的特征在于，包括投影仪，被分成词组和图形并利用光源照亮生成的信息；透镜，传输信息；反射器，将信息的部分信息反射到透镜；以及屏幕，显示从透镜传输的部分信息。
作为优选实施方式，投影仪将信息区分为后方信息、号码信息和驾驶信息。号码信息和驾驶信息作为部分信息从反射器被反射。
作为优选实施方式，投影仪包括：照亮后方信息的后方向导信息投影仪、照亮驾驶信息的驾驶信息投影仪以及照亮号码信息的号码信息投影仪。后方向导信息投影仪和驾驶信息投影仪配置成分别显示多个投影。
作为优选实施方式，反射器相对于透镜倾斜，以便将部分信息反射到透镜，同时透镜处于水平状态。
作为优选实施方式，屏幕在上部和下部显示部分信息。
作为优选实施方式，投影仪通过投影控制器执行信息生成和执行照明。投影控制器包括：用于语音识别的语音识别模块、用于与移动设备互锁的多媒体模块、以及用于与车辆系统互锁的扩展模块。

参照图1，外部车辆通知信息系统1包括投影仪10、光源20、透镜30、反射器40、屏幕50和投影控制器60。
具体地，投影仪10生成外部车辆通知信息，并且接收光源20，以向外界照亮生成的外部车辆通知信息。外部车辆通知信息指示倒车和注意警告(例如，词组、安全距离、三脚架(tripod)显示)的后方信息200、车辆登记号码的号码信息300(参见图4)以及表示驾驶员意图的驾驶信息400(例如，诸如故障、制动和让车等的文本消息)(参见图5)。为此，投影仪10优选为小尺寸的数字光处理(Digital Light Processing，DLP)投影型投影仪，并且使用由驾驶信息投影仪13-1和号码信息投影仪13-2组成的车辆信息投影仪13以及后方向导信息投影仪11将其整个空间划分为三级区域。
具体地，光源20产生用于投影仪10的信息照亮的光，并且由发光件组成。透镜30以水平状态从投影仪10的照明方向向下布置，并且将从投影仪10照亮的信息分成向导信息投影仪11、驾驶信息投影仪13-1和号码信息投影仪13-2并供其通过。反射器40放置在透镜30上方，同时在投影仪10的照明方向上以锐角的安装角度(Ka)倾斜地面向投影仪10，并且朝向透镜30反射从投影仪10发射的光。在这种情况下，可以根据透镜30的布置和投影仪10的信息显示方向适当地改变反射器40的安装角度(Ka)。
具体地，屏幕50显示通过透镜30的投影仪10的信息。特别地，考虑到后方向导信息投影仪11的信息偏离屏幕50的特性，屏幕50向上显示驾驶信息投影仪13-1的信息，向下显示号码信息投影仪13-2的信息。在这种情况下，屏幕50的安装角度(Kb)相对于其水平线形成锐角，但是可以根据透镜30和反射器40的布置适当地改变。
具体地，投影控制器60包括语音识别模块60-1、多媒体模块60-2和扩展模块60-3。例如，语音识别模块60-1具有通过识别命令进行显示的功能。多媒体模块60-2具有与智能电话互锁(interlocking)以进行显示的功能。扩展模块60-3具有与其他系统(例如，车辆系统)互锁以进行显示的功能。
同时，参照图2中的投影布局，投影仪10通过后方向导信息投影仪11、驾驶信息投影仪13-1和号码信息投影仪13-2的各种布局来实现显示多样化。本文定义了以下信息：①，从后方向导信息投影仪11发送的将在屏幕50上显示的外部车辆通知信息；②，从驾驶信息投影仪13-1发送的将在屏幕50上显示的外部车辆通知信息；以及③，从号码信息投影仪13-2发送的将在屏幕50上显示的外部车辆通知信息。
图2左侧所示的投影仪10是使用五个投影仪的五层布局投影的示例。相应地，在五层布局投影中，后方向导信息投影仪11由被视为一对的第一投影仪11a和第二投影仪11b组成，驾驶信息投影仪13-1由一个投影仪组成，号码信息投影仪13-2由被视为一对的第三投影仪13-2a和第四投影仪13-2b组成。
图2中间所示的投影仪10是使用三个投影仪的三层布局投影的示例。相应地，在三层布局投影中，后方向导信息投影仪11由一个投影仪组成，驾驶信息投影仪13-1由一个投影仪组成，并且号码信息投影仪13-2由一个投影仪组成。
图2右侧所示的投影仪10是使用一个投影仪的单层布局投影的示例。相应地，单层布局投影使用一个投影仪构成后方向导信息投影仪11、驾驶信息投影仪13-1以及号码信息投影仪13-2。
因此，与一个投影仪相比，五层布局投影可以使由第一投影仪11a和第二投影仪11b组成的后方向导信息投影仪11的显示信息多样化，并且与一个投影仪相比，第三投影仪13-2a和第四投影仪13-2b可以使号码信息投影仪13-2的显示信息多样化。相应地，与三层布局投影和单层布局投影相比，五层布局投影会在屏幕50上显示各种词组、图形等。
同时，图3至图5示出了应用外部车辆通知信息系统1的车辆100，以及示出了通过投影仪10的各种显示器显示外部车辆通知信息的状态。
参照图3，在车辆100中，外部车辆通知信息系统1被安装到后备箱110的牌照安装部110-1。
具体地，后备箱上面板111被分成后备箱下面板113和后备箱内面板115，以安装外部车辆通知信息系统1。
具体地，外部车辆通知信息系统1由投影仪10、光源20、透镜30、反射器40、屏幕50和投影控制器60组成，并且与通过图1和图2描述的外部车辆通知信息系统1相同。然而，不同之处在于，外部车辆通知信息系统1将光源20用作照亮车辆牌照的牌照灯，而不是单独光源。此外，不同之处还在于投影控制器60将语音识别模块60-1与车辆语音识别系统120-1关联，将扩展模块60-3与车辆系统120-2关联，并将多媒体模块60-2与智能电话120-3关联。
就外部车辆通知信息系统1的安装结构而言，投影仪10、光源20、透镜30、反射器40和屏幕50布置如下。
作为示例，投影仪10被放置在后备箱内面板115的内部空间中以朝向后备箱上面板111照射光，并且使用作为光源20的牌照灯产生光。透镜30被放置在水平弯曲部分，使得后备箱上面板111形成牌照安装部110-1，并且朝向牌照安装部110-1发送从反射器40反射的投影仪10的照明光。特别地，反射器40被安装成以倾斜的安装角度朝向后备箱上面板111的水平弯曲部分，并且向透镜30反射投影仪10的照明光。特别地，为了满足车辆牌照照明规定，反射器40的倾斜安装角度要保证总能照亮牌照安装部110-1的牌照。
作为示例，屏幕50连接至牌照安装部110-1。投影控制器60可以安装在后备箱110的后备箱室、车内或引擎室的任意一者中。
就外部车辆通知信息系统1的操作而言，投影控制器60的语音识别模块60-1、多媒体模块60-2以及扩展模块60-3按如下方式提供。
作为示例，语音识别模块60-1关联到车辆语音识别系统120-1，并且作为车辆语音识别系统120-1的功能件，可以根据车辆内的语音命令通过投影仪10和反射器40在屏幕50上进行显示。
作为示例，扩展模块60-3关联到车辆系统120-2，并且作为车辆系统120-2的功能件，提供由各种方式表示的词组作为实现屏幕50的显示功能，例如当操作倒车档时在后方显示的“倒车”字样，当按下制动器时显示的“制动”字样，当车辆停止后打开车门时显示的“上/下车”字样。另外，扩展模块60-3作为车辆系统120-2的功能件，当夜间操作倒车档使用照度传感器进行识别时，可以通过与投影仪10的后方向导信息投影仪11互锁而起到倒车向导的作用。
作为示例，多媒体模块60-2关联到智能电话120-3，并且作为智能电话120-3的功能件，可以通过与智能电话互锁来改变屏幕50的显示词组。
参照图4，可以看出，后方信息是使用车辆100中的外部车辆通知信息系统1生成的。
如图所示，投影仪10使用后方向导信息投影仪11将生成的后方信息照射到透镜30。然后，后方信息不从反射器40反射，而是直接通过透镜30传输。结果，后方信息显示在车辆后侧的路面上。
具体地，后方向导信息投影仪11通过基于后方信息而改变照明角度来通知后方车辆涉及各种类型的、多样化的后方信息的车辆状态。
作为示例，后方信息被分成第一向导信息200-1、第二向导信息200-2和第三向导信息200-3。第一向导信息200-1作为在道路上传输的三脚架显示信息，被传输到离车辆最远的后方位置，以实现三脚架显示。第二向导信息200-2作为传输到道路上的“停止”词组，被传输到后方车辆不与车辆碰撞的后方位置，以实现“停止”信息显示。第三向导信息200-3作为传输到道路上的安全距离显示信息，从车辆被传输到适当位置，以实现安全距离信息显示。
参照图5，可以看到使用车辆100中的外部车辆通知信息系统1生成驾驶信息和号码信息的示例。
如图所示，投影仪10同时向反射器40示出了使用驾驶信息投影仪13-1生成的驾驶信息和使用号码信息投影仪13-2生成的号码信息。然后，通过使驾驶信息的反射角比号码信息的反射角更向下，反射器40在号码信息下方形成通过透镜30传输的驾驶信息。结果，屏幕50在其上部显示号码信息，在其下部显示驾驶信息。
具体地，号码信息投影仪13-2通过号码信息300生成车辆登记号码，但是驾驶信息投影仪13-1通过驾驶信息400应用各种词组来通知后方车辆涉及各种类型的、多样化的驾驶信息的车辆状态。
作为示例，驾驶信息400被分成第一驾驶信息400-1、第二驾驶信息驾驶信息400-2、第三驾驶信息400-3、第四驾驶信息400-4、第五驾驶信息400-5和第六驾驶信息400-6。第一驾驶信息400-1指示显示为车辆登记号码下的“求助”的帮助请求信息，第二驾驶信息400-2指示显示为“上/下车”的因乘客上下车引起的车辆停止信息，第三驾驶信息400-3指示显示为“正在修理”的因故障引起的车辆停止信息，第四驾驶信息400-4指示显示为“倒车”的因倒车引起的车辆移动信息，第五驾驶信息400-5指示显示为“制动”的因制动操作引起的车辆制动信息，第六驾驶信息400-6指示显示为“让车”的驾驶员让车信息。
在这种情况下，第一驾驶信息400-1、第二驾驶信息400-2、第三驾驶信息400-3、第四驾驶信息400-4、第五驾驶信息400-5和第六驾驶信息400-6的信息和词组可以通过将投影控制器60的语音识别模块60-1、多媒体模块60-2和扩展模块60-3与车辆语音识别系统120-1、智能电话120-3和车辆系统120-2中的每一个进行关联来实现各种改变。
如上所述，本公开的应用于车辆100的外部车辆通知信息系统1安装到后备箱110，以向车辆100后方的后方车辆通知倒车和注意警告的后方信息200、车辆登记号码的号码信息300以及驾驶员意图的驾驶信息显示，从而实现更稳定和安全的驾驶，特别是通过投影视频技术来显示外部显示信息，从而无论白天和黑夜都保持对附近车辆的高可视性。
虽然已经通过特定实施方式描述了本公开，但是对于本领域的技术人员来说显而易见的是，在不脱离如所附权利要求所限定的本公开的精神和范围的情况下，可以进行各种改变和修改。
