具体实施方式
当前示出的实施例主要在于与车辆视觉系统相关的方法步骤和设备部件的组合，特别是在车辆后视组件中具有显示装置的车辆视觉系统。因此，已经提出了设备部件和方法步骤，在适当的情况下，通过附图中的通用符号仅示出与理解本发明的实施例有关的那些具体细节，以免通过对于受益于本文的说明书的本领域技术人员容易想到的细节来使本公开模糊。此外，说明书和附图中的相同附图标记表示相同元件。
为了在此进行说明，术语“上部”、“下部”、“右”、“左”、“后部”、“前部”、“竖直”、“水平”及其派生词应涉及如在图3A和图3B中定向的发明。除非另有说明，术语“前部”应该指代元件的更靠近后视组件的预定观察者的表面，术语“后部”应该指代元件远离后视组件的预定观察者的表面。然而，可以理解的是本发明可以采取各个可替代定向，除非明确相反地指定。还可理解的是附图中示出以及以下说明书中说明的具体装置和处理仅是限定在随附权利要求中的发明构思的示例性实施例。因此，关于本文中公开的实施例的具体尺寸和其他物理特征不被视为限制，除非权利要求明确地否定声明。
术语“包括”、“包含”、“含有”或其任何其他变型旨在覆盖非排他性内容物，使得包括一系列元件的处理、方法、制品或设备不包括仅这些原件，而可以包括对于这些处理、方法、制品或设备而言未明确列出或固有的其他元件。在前为“包括…”的元件在没有更多限制的情况下不排除包括该元件的处理、方法、制品或设备中存在另外的相同元件。
本文中说明的实施例涉及车辆视觉系统。已知车辆视觉系统，其中照相机安装至车辆上，用于捕获显示在定位在车辆中的显示装置上的图像，用于由车辆的驾驶员观察。在这些车辆视觉系统的一些中，显示器位于内部后视镜组件中。这些显示器在尺寸上小于镜元件并且定位在镜元件的后面，使得由显示器产生的图像在显示器被激活时可以通过镜元件被看到。此外，镜元件可以是半透射的以便当未激活时隐藏显示器。在一些这种视觉系统中，显示器的功能是倒车照相机显示器(RCD)的功能，其中当车辆置于倒挡时激活显示器并且显示器显示来自后向照相机的图像持续车辆保持倒挡那么长或者此后持续预定时间。这些RCD一般具有小于镜元件的视域。RCD的例子在美国专利No.8,339,526和美国专利申请公开No.US 2009/0096937A1中进行了说明，其整体公开内容通过参引进行结合。
一些车辆视觉系统设计成具有包括基本对应于镜元件的面积的显示器。在这些系统中，显示器构造成每当由驾驶员激活时显示来自后向照相机的图像。这些“完整显示镜”(FDM)的例子在美国专利No.8,339,526、美国专利申请公开No.US 2009/0096937A1、US2015/0266427A1和US 2015/0277203A1中进行了说明，其整体公开内容通过参引进行结合。
在车辆视觉系统中，可能需要从认可立场使显示的图像模拟一个人将通过从常规镜的反射看到的图像。另一方面，从安全性立场可能所期望的是显示比利用常规镜所看到的更大的视野。在相机一般安装在车辆外部以便不使其视野被车辆中的物体或车辆的与后窗玻璃相邻的后柱而被遮蔽的情况下上述后一个目标是可能的。为了适应这些看上去不相容目标，本文中说明的实施例允许驾驶员选择待显示的视野。如下所述，这可以通过在驾驶员使镜壳体运动时或者在驾驶员操纵用户输入时改变视野来实现。视野的改变可以以模拟在移动常规镜壳体时驾驶员将经历的视野的改变的方式来执行。
图1中示出车辆视觉系统10的示例。如图所示，车辆视觉系统10包括照相机系统20和显示系统30。在照相机系统20和显示系统30可以定位在车辆的独立的位置以及布置在不同的车辆部件或附件中的情况下，照相机系统20和显示系统30显示为两个独立的系统。例如，如以下进一步说明的，显示系统30可以布置在后视组件100(图3A、图3B和图5)中，而照相机系统20可以布置在车辆的后部和/或侧面。
图2A和图2B示出本文中说明的实施例的两个不同的实施方式。在图2A所示的实施方式中，照相机系统20包括捕获视野的图像的照相机25。显示系统30包括运动传感器32、显示驱动器34、显示装置35和处理电路40。显示装置35构造成显示通过照相机捕获的视野的一部分。显示系统30可以完全地或局部第二位布置在车辆中，使得显示装置35相对于车辆可移动地安装。运动传感器32设置用于感测显示装置35的运动。如以下详细地描述的，处理电路40与运动传感器32、显示装置35(经由显示驱动器34)和照相机25连通，用于响应于由运动传感器32感测的显示装置35的运动来选择待显示在显示装置35上的视野的部分。
图2B中示出的实施方式与图2A所示的实施方式的不同之处在于处理电路40是照相机系统20的一部分并且因此可以与照相机25位于相同的车辆部件或附件中。在该实施方式中，处理电路40经由车辆总线或分立连接接收来自运动传感器32的输出，并且响应于由运动传感器32感测的显示装置35的运动选择待显示在显示装置35上的视野的部分。可选的处理器42可以设置在显示系统30中以便于与处理电路40连通并且执行用于显示系统30布置其中的部件的任何其他处理功能。例如，如果设置在后视组件中，处理器42可以构造成计算罗盘传感器的航向、控制电子光学镜元件变暗或者执行通常由镜壳体中的处理器执行的任何其他功能。尽管显示为照相机系统20或显示系统30的一部分，但是处理电路40可以与任一系统分离地定位。
如上所述，显示系统30可以安装在后视组件100中。如图3A所示，后视组件100可以包括布置在镜壳体120中的显示装置35，显示装置35定位以及定尺寸成以便作用为RCD，其中显示区域小于后视组件的总可视区域。后视组件100可以包括在显示装置35的前面或后面布置在镜壳体120中的镜元件140，使得后视组件100作用为后视镜组件。镜元件140可以包括在显示装置35前面的透射窗口141(图5)，使得来自显示装置35的所显示的图像可以通过镜元件140被看见。镜元件140可以在其整个可视区域上或在窗口141内是半透射的，使得显示装置35在不被激活时隐藏。
如图3B所示，后视组件100可以包括布置在镜壳体120中的显示装置35，显示装置35定位以及定尺寸成以便作用为FDM，其中显示区域与后视组件的总可视区域基本相同尺寸。镜元件140可以在其整个可视区域上是半透射的，使得显示装置35在不被激活时隐藏。对于RCD和FDM两种型式的后视组件100而言，用户致动开关200可以设置用于以美国专利申请公开No.US 2009/0096937A1、US 2015/0266427A1和US 2015/0277203A1中公开的方式激活或停用显示装置35，上述美国专利申请公开的全部内容通过参引结合到本文中。在开关200的用户激活可能引起显示装置35运动的程度上，由于开关200的致动将停用显示装置35或将其从在前的停用状态激活，因此如果检测到开关200的致动，则可以超越(override)由运动传感器32感测的任何运动。
图4A示出具有虚线所示的视野80的部分82a的照相机25的镜像成像(或反向)视野80的示例。部分82a旨在示出显示在显示装置35上的视野的部分。如图所示，照相机视野80大于待显示的部分82a。如上所述，特别是当显示器构造为FDM时，可能希望模拟后视镜。由于后向照相机将图像直接捕获至如由驾驶员看到的与镜象相反的后部，因此可能期望的是在显示在显示器35上之前反向由照相机捕获的图像，使得所显示的图像看起来如同其在从镜像反射时那样。此外，在仅具有镜元件的后视镜组件中，镜壳体120的运动从驾驶员来看改变了视野。然而，在常规FDM中，在照相机相对于车辆保持固定时镜壳体的运动不会引起所显示的视野改变。因此，处理电路40设置并构造成响应于由运动传感器32感测的任何运动选择显示在显示装置35上的照相机视野80的部分82a。因此，例如，响应于镜壳体120的水平旋转，处理电路40通过选择视野80的从在前显示的部分82a(图4A)水平地偏移的部分82b(图4B)转变所显示的视野。所显示的部分可以逐渐地以及连续地转变以模仿使镜元件以相同方式运动的视野的改变。类似地，响应于镜壳体120的竖直倾斜，处理电路40通过选择视野80的从在前部分82a(图4A)竖直地偏移的部分82c(图4C)转变所显示的视野。
尽管单个照相机的单个视野如上所述，但是视野80可以是来自多个照相机的复合视野，图像合并在一起以形成一个无缝全景图像。因此，镜壳体120的运动可以实现或禁用不同的照相机或者另外从特定照相机的视野选择，使得镜壳体120的运动使得显示装置35的视野有效地平移更大的全景视野。应注意到还可能设置用户可选择机构以允许驾驶员放大或缩小显示视野。
还应该理解的是可以通过使照相机25在能够平移和倾斜的情况下进行平移和倾斜来在镜壳体120的整个运动中改变显示视野。
图5示出示例性后视组件100的分解图。如图所示，后视组件100包括镜壳体120和安装结构445，安装结构445用于将镜壳体120枢转地安装至车辆，使得镜壳体120可以相对于车辆竖直地和水平地倾斜。在图5中，附图标记240表示安装结构445的安装脚450可以固定其上的车辆的挡风玻璃。本领域技术人员将理解的是，安装结构445可能可替代地紧固至车辆的挡风玻璃以上的车顶结构。在一些应用中，单个球安装架是优选的，使得在单个球上的旋转位置的测量值准确地表示镜在车辆中的位置。安装结构445还包括安装球501和在球501与安装脚450之间延伸的安装杆502。
镜元件140安装在镜壳体120中。可选的罗盘传感器320可以布置在镜壳体120中并且联接至处理电路40(或处理器42)。罗盘传感器320大致包括X轴磁场传感器440、Y轴磁场传感器460和可选的Z轴传感器(未示出)。传感器440和460以及处理电路40可以安装在印刷电路板160上。
显示装置35固定地安装在镜壳体120中以及可以安装在印刷电路板160的前表面上或安装至镜元件的后表面，以便通过设置在镜元件140的反射表面中的窗口部分141投射光。显示装置35可以可替代地安装在子系电路板(未示出)上。此外，显示装置35可以安装在镜元件140的前面。
镜元件140可以是电子光学镜。用于自动地改变透射率以及由此改变电子光学镜元件140的反射率的传感器和电路也可以安装在印刷电路板160上。这种电路可以经由导线142以任何常规方式联接至镜140。
如上所述，后视组件100还包括用于检测镜壳体120以及因此显示装置35何时从在前位置运动的运动传感器32。运动传感器32然后产生并且向处理电路40传送运动检测信号，使得处理电路40在向显示器选择照相机视野的一部分时考虑镜壳体120以及由此显示装置35已被倾斜的事实。
运动传感器32可以具有能够感测镜壳体120的运动的任何结构。用于感测镜壳体的运动的运动传感器的例子在美国专利No.6,140,933中公开，该专利的全部公开内容通过参引结合。如下参照图6A-6C说明美国专利No.6,140,933中公开的一个这种运动传感器的示例。
在图6A和图6B中，示出用于单个球镜安装架(mount)445(图5)的枢转球501、电路板160的一部分以及用于测量镜壳体120在安装架上的位置的部件。球501通过杆502经由安装支架450(图5)附装至汽车。从侧面观察组件。目标501a设置在枢转球501上。四个LED中的两个LED506和507示出中图6A和图6B中，并且分别地布置在传感器516以下和以上，以及用于感测镜壳体120的竖直运动。这些LED可以一次一个地瞬时点亮，通过可以是光电二极管的传感器516测量通过LED中的每一个从目标501a单独地反射的光。如图6C所示，运动传感器32还可以包括横向地布置在传感器516的任一侧上用于感测镜壳体120的水平运动的LED508和509。
目标501a可以是设置在黑色或深色球501上的白斑。相反地，目标可以是白色或高度反射球501上的黑斑。基本地，目标可以是与镜球相反的任何颜色，在此“颜色”定义为在被使用的光谱下的反射。一般地，测量的是目标区域501a与周围区域之间的对比差。目标可被喷涂在球501、分离的塑料构件、不干胶或甚至球501的表面组织中的变化上。另外，空隙可以模制在球501中，看上去像是光背景上的黑色目标。此外，球501可以由金属制成并且具有镜像成用作目标501a的部分。
运动传感器32还可以通过比如为设置在镜壳体120中的三轴罗盘传感器的磁场传感器提供，如美国专利No.6,928,366中公开的三轴罗盘传感器，该美国专利的全部内容通过参引结合。还可能期望在镜壳体120的顶部和底部上的位置处提供电容接触式传感器，驾驶员可能在镜壳体120的顶部和底部处抓握镜壳体120以便使其运动。这种电容接触式传感器因此将提供用于处理电路40的附加信息，以确定镜壳体120已由驾驶员移动。
尽管实施例如上所述为适用于内部后视组件，但是显示装置同样可以定位在外部后视组件中。在该例子中，由于大多数车辆不需要驾驶员物理上地使外部镜元件运动，运动传感器32(图1)可以是用户输入31的一部分以便感测用户输入机构33的运动。用户输入机构33可以采取用于使外部镜运动的任何常规机构的形式，比如用于使镜元件左、右、上、下运动的操纵杆或多重开关。运动传感器32因此可以根据所采用的用户输入机构33的形式不同地构造，并且可以以与常规镜位置开关相同的方式构造。该布置与常规布置之间的主要区别在于处理电路40通过选择视野的待显示在显示装置35上的部分响应用户输入31。这可以避免对马达组件的需要，否则将需要物理地移动常规外部镜元件。
尽管这种输入31的使用已相对于外部镜组件进行了说明，但是用户输入31可以设置成当如上所述地定位在比如内部后视组件100的内部位置中时调整显示在显示装置35上的视野。此外，同一用户输入31可以通过提供选择器开关而被用于内部后视组件100和两个外部组件，以便选择在其上调整视野的显示器。
上述说明仅视为优选的实施例。本领域技术人员以及制造或使用本发明的人员将想到本发明的改进。因此，应当理解的是附图在所示以及如上所述的实施例仅用于例示目的并非旨在限制本发明的范围，本发明的范围由如根据专利法的原理，包括等同原则，解释的权利要求所限定。
