Description

具有摄像机和监视器II的商用车辆的后视镜
技术领域
本发明涉及一种车用后视镜,特别是涉及一种用于商用车辆的后视镜,其中,根据权利要求1的总体概念所述的该后视镜具有光学成像装置。
背景技术
US-PS-4,882,565披露了一种车用后视镜,其中在反射表面中结合有指示装置,该指示装置提供有来自安装在镜子表面背后的照明部件的光。采用该装置,简单的警告信号或各种功能单元的程式化的图象可以被显示并且呈现在后视镜上,以引起注意。在这里没有提出显示由摄像机产生的图象。
在将车辆从辅道转向主大道的时候,通常司机在转向之前会使用后视镜。在右转时,他不仅要利用具有可见的后面区域的右侧镜,而且要在他的视野内看到镜子上面的右前方。为了知道左侧的危险或交通,他必须转头,并且如果必要的话,需要使用左后视镜。因此,在交通拥挤的情况下,他被迫改变视线的方向和其头部的位置,其中相应地,在注意一侧的同时,就不会注意到另一侧。这就会导致危险的发生。
发明内容
本发明的目的在于提出一种具有光学成像装置的后视镜,它具有这样的特征,即该车辆周围的大部分不同区域将会得到司机的注意。
该目的是通过权利要求1的特征来实现的。
通过设置安装在后视镜中的监视器,由摄像机所产生的图象可以被传送到所述监视器中。该摄像机可以朝向在司机观察该镜子时不处于其视角中的视场。利用本发明的优点,司机看一眼就不仅能够看清楚直接位于镜子的反射角中的区域以及镜子前面的区域,而且能够在镜子中的监视器上看到其它区域,而不需要改变视线方向或转头。该监视器优选采用LCD图象,并且该摄像机优选为CCD摄像机。
根据本发明的一个优选实施例,为了不妨碍该镜子的基本用途,该监视器安放在镜子的边缘区域中,即安放在镜面的边缘区域中。这就可以使监视器不必被结合进镜面中,而优选地可安放在镜面下方、外部或上方位置上。该监视器的安装可以通过镜壳中适当的凹槽来完成。
根据权利要求3所述的本发明的优选实施例,摄像机可以类似地被安装在镜壳内。从而可以通过该镜壳中的相应开口使得光入射在该摄像机上。
根据权利要求4所述的本发明的优选实施例,摄像机被设计成可绕枢轴转动,这样车辆周围的不同区域就能够进入视线并显示在监视器中。当要倒车时,能够在监视器中看见车后的的区域。
根据权利要求7所述的本发明的另一个优选实施例,允许使用多个摄像机。采用这种多摄像机的设置,通过各摄像机之间的切换可将车辆周围的不同区域显示在监视器中。
如果采用后一方案,则该摄像机的转动则变得多余了。相应的摄像机可以被安装在最佳位置中,以扫描当前所要监视的区域。用于倒车操作的摄像机从理论上讲应安装在车辆的后面。
如果另外可使用多个监视器的话(参见权利要求8),则在特定的情况下,从一摄像机到另一摄像机的选择性切换便变得没有必要了,因为每个摄像机都能够被分配一个监视器。另外,在各个监视器上,尤其是在显示的不同区域中,可在一个监视器中显示出附加的数据,例如温度、速度、所确认的后面、前面或侧面的间距可以被显示出来。监视器的不同显像区域应该被理解成,在监视器上,不同的内容可以通过在图象格式内的图象显示出来。
根据如在权利要求9中所述的另一个优选实施例,后视镜能够包含第一和第二监视器。第一监视器与一个后视镜中的摄像机相连,第二监视器与车辆另一侧的后视镜中的摄像机相连。因此,该布置使得看一眼就能够扫描到车子周围更大范围内的区域。
通过如由权利要求11和12所教导的图象和数据存储装置,能够产生实质上类似于“黑匣子”的功能。为此,来自一个或多个摄像机的最后五分钟内的连续图象可以被保存在存储器中。或者,相关的数据例如温度、天气、时间和速度也能够被保存。这样,事故过程就能够更容易地被重构出来。
根据权利要求12,监视器的成像表面与镜子的表面具有不同角度。这是为了防止在监视器中出现与在镜子中所正常反射出的图象一样的图象。
通过数字变焦,也就是说通过成像成分的数字选择,如 13所述的一样,可以实现与由绕枢轴转动摄像机所得到的类似功能。
根据如权利要求14至17所述的优选实施例,该监视器可被设计成以这样的方式结合进镜子中,以使得监视器即监视器的表面在处于非启动状态下是看不见的(或者几乎看不见)。这就给为该监视器表面设置局部反射部件提供了自由。或者,如果监视器被安装在镜面的后面的话,则其后面有监视器的所述镜面的区域可以同样只是局部地或者“半镀银”地具有反射部件。在该情况下,监视器前面区域中的镜面的反射涂层设有间隔的开口,以便获得局部的更高镜面透光度。该反射层的间隔可以呈例如薄的相对彼此平行的条带的形式。反射涂层还可以呈小的独立点的形式。如果该反射区域是以这种方式局部开口的话,则后视镜的后视能力只被限定在较小的程度。然而,可以获得高的镜面局部透光度,这样虽然该监视器在其未启动状态下是看不见的,但是在其启动状态下是看得见的。该反射层的面密度的降低可以通过如在所述涂层被涂覆在镜面上时利用激光、蚀刻或铭刻工艺或通过适当的掩蔽法来实现。
附图说明
本发明的进一步的细节、特征和优点能够在附图的帮助下由以下优选实施例的描述来得出。
其中:
图1为本发明的第一实施例的剖视图;
图2为根据第一实施例的镜子的前视图;
图3为本发明第二实施例的示意图;
图4为本发明的第三实施例的侧视图;
图5为根据第三实施例的镜子的前视图;并且
图6为本发明第四实施例的示意图。
具体实施方式
在图1和2中,显示出本发明的后视镜的第一实施例。该后视镜包括镜壳2、可调节地安装在所述镜壳2中的镜面4以及光学成像装置,该光学成像装置以监视器6的形式结合进镜子表面。同样,在镜壳2中包括有摄像机(尤其是CCD摄像机8),该摄像机通过朝向运动方向的孔10打开。该监视器6通过电缆12与摄像机8相连。这样,左后视镜的镜壳2中的摄像机8优选地被调节成具有向前和向右的角度,因为这样在司机看所述左后视镜时可将不处于可见部分中的区域带进视线中。
监视器6以LCD显示器的方式被结合进镜面4中,其中所述LCD显示器的表面仅仅是半镀银的,这样该监视器6在LCD显示器的未启动状态下几乎是看不见的。或者,该监视器6可以被安装在镜面4的后面,在该情况下,所述镜面在监视器的区域中是半镀银的,这样,在其启动状态下的监视器的显示是可见的,并且该监视器在未启动状态下是看不见的。
图3以示意的方式说明了本发明的第二实施例,该实施例包括第一摄像机8-1和第二摄像机8-2以及监视器6,该监视器具有左观察部分6-1和右观察部分6-2。如由电缆12-1和12-2的存在所表明的一样,第一摄像机在左显像区域6-1上成像,第二摄像机6-2在右显像区域6-2上成像。与第一实施例相反,该监视器没有结合进镜面4中,而是安装在镜壳2的下面。
该第一摄像机8-1管理沿着运动方向所看到的车辆左侧的视野,并且将图象产生在左侧的显像区域6-1上。第二摄像机8-2扫描车辆右侧的区域,并且该图象被产生在右侧的显像区域6-2上。
图4和5描述了本发明的第三实施例,其中显示出第二实施例的变型。根据第三实施例的后视镜包括具有镜面4的主镜14和叠置在主镜14上的辅助镜16,该辅助镜16设有单独的壳体17和镜面18。
第一摄像机8被安装在左侧后视镜的辅助镜壳体17内,通过开口,其视场指向运动方向。未进一步说明的第二摄像机被安装在右侧后视镜中。在主镜14的镜面4的下面区域中设有具有左、右图象显像区域的监视器6。通过电缆12,第一摄像机和左显像区域6-1相连并且第二摄像机(未示出)在司机左侧的后视镜中与右显像区域6-2相连。
监视器6的安装是以与在图1和2的实施例中所示的方式一样的方式来完成的,这样监视器6的两个显像区域6-1和6-2同样在它们的未启动状态下变得看不见。
图6显示出的本发明的第四实施例,其具有面朝前面、绕枢轴转动的摄像机20,该摄像机位于拖拉车车顶的顶侧上,其还具有在所述拖拉机的尾部面向后面的摄像机22。在左侧安装有后视镜26、监视器6,这就使得能够选择性通过操作装置与向前的绕枢轴转动的摄像机20或与后面的摄像机22相连。绕枢轴转动的摄像机20可以在操作装置24的作用下转动,从而该摄像机20的视野能够在很大程度上变化。
当要倒车时,通过由操作装置24进行相应的切换,从而后视摄像机22的图象就会被切换到监视器6上,这样在左侧后视镜26中,显示出摄像机22的视场。一旦需要,司机可以再次利用所述操作装置24重新将向前的摄像机20的视场显示在监视器6上。
根据图6的第四实施例允许其自身如在第二和第三实施例中的情况下一样进行改变,即设置两个显像区域或用于两个摄像机的两个监视器。
