Description

汽车智能远光灯控制开关 技术领域
本发明涉及汽车灯光智能技术领域，具体为汽车智能远光灯控制开关。
背景技术
目前汽车大灯智能控制系统已在汽车上广泛应用，夜降临时或者车过桥洞逐道等光线较暗时，汽车大灯会自动开启，当光线充足时会自动关闭。但是几乎百分之九十五以上车的远光灯不具有此功能。具权威机构统计夜间行车因远光灯操作不当而造成的交通事故占35％以上。
为什么控制原理与自动感应大灯一样而在远光灯上就不能实现呢？下面是实测举例说明：天黑后在无路灯的道路上用光照计测试,所测位置在驾驶室正前方。当自己车的所有车灯都关闭，前方无仼何车灯时，前方10米和100米测得的光照度均为为0.3Lux左右。当前方迎面100米有车大灯开时，前方10米测的还是0.3Lux，前方100米为0.6Lux。看来可从通过这一光照度的变化来控制运光灯了，但是当自己所驾驶的汽车远光灯开着时，前方10米的光照度就是0.9Lux了，远大于100米迎面大灯的光照度。所以当自己驾驶的车远光灯打开后其光照度己将100米的车大灯照度复盖了，通俗一点就是自己驾驶车远光灯亮度比迎面100米的车灯亮。所以为什么直到目前为止远光灯自动感应控制的应用比较少。那么个别高端车是怎样实现这一功能的。在车的后视镜背面对行驶前方装有一个摄像头和测距仪，当天黑时摄像头扑捉行驶前方远处的光点，对这一光点进行复杂的运算来判断前方是否有行驶的车辆，从而来控制自己所驾车的远光灯开启或关闭。还有一个安装车型的不同，如小车和大车本身开启远光灯后，其所测的光照度也不一致，所以通过光强弱来判断只能满足汽车大灯的自动控制，根本达不到自动控制远光灯的要求， 为此，我们提出汽车智能远光灯控制开关。
发明内容
本发明的目的在于提供汽车智能远光灯控制开关，以解决上述背景技术中提出的问题。
为实现上述目的，本发明提供如下技术方案：汽车智能远光灯控制开关，包括探头和电子开关，所述探头与电子开关电性连接，所述电子开关和探头均串联在汽车远光灯控制线的输出端上，且汽车远光灯控制线的输出端与汽车的远光灯电性连接；
所述探头包括感光装置、LED指示灯、控制单元和电子开关，所述感光装置与控制单元电性连接，所述LED指示灯与控制单元电性连接，所述控制单元与电子开关电性连接；
优选的，所述感光装置包括安装板、感光元件和遮光套，所述感光元件与遮光套均固定在安装板上，且感光元件与遮光套位于同一侧，所述感光元件外套有一个以所述感光元件为中心的遮光套，所述遮光筒突出感光元件感光平面5毫米以上，所述遮光套内部中孔，且感光元件位于遮光套的内部。
优选的，所述遮光套为圆柱体，且遮光套的长度大于感光元件的长度。
优选的，所述电子开关包括电源模块和MOS三极管组件，所述控制单元通过电压为3.3V的电线与电源模块电性连接，所述控制单元通过控制线与MOS三极管组件的一端电性连接，所述电源模块与MOS三极管组件均串联在汽车远光灯控制线上。
优选的，所述感光元件与LED指示灯均接地连接，所述电源模块与MOS三极管组件的一端均接地连接。
优选的，所述探头固定安装在驾驶室仪表台面上或者方便驾驶员可视角 度的任一位置。
与现有技术相比，本发明的有益效果是：
1、本发明可以实现自动开关远光灯这一功能，自己所驾驶汽车的远光灯已打开，而迎面100米外有开着大灯(并非远光灯)或者有开着摩托车大灯的车辆时，虽然自己车远光灯的亮度远比100米处的车大灯亮，还是可以判断前方有车，本发明装置自动关闭自己驾驶车的远光灯。
2、本发明感光元件是一只光敏三极管，关键在于在光敏三极管的外面套有一个和光敏三极管外径稍大点的空心管子(遮光套)，管子长度略突出光敏三极管感光面一小段长度，光是直线传播，如图没有遮光套的光敏三极管所探测到的光线是散开的，就是说离光敏三极管较近的光线也会被探测到即本车远光灯亮时也会被测到而且照度信号还较大。那么套着遮光套的光敏三极管因感光面被遮光套的突出部份遮档，离光敏三极管较近的光线也被遮挡(见附图)。这样探测到本车所发出的远光灯光照度会大大减弱，当前方100米有车灯亮时，所测所的亮度信号不会被复盖和干扰，该发明还可以屏蔽掉因本车灯照在道路两侧障碍物而发出的反射光。

所述感光元件8与LED指示灯4均接地连接，所述电源模块10与COS三极管的一端均接地连接。
所述探头1固定安装在驾驶室仪表台面上或者方便驾驶员可视角度的任一位置。
工作原理：汽车原车远光灯开关打开后，本发明装置开始工作，当探头1检测到光线较暗时车辆正前方无任何车大灯亮即没有迎面而来的汽车，控制单元5向MOS三极管组件11组成的电子开关6发出电子开关6导通指令，远光灯亮，反之当有开着大灯的车迎面而来时，探头1的控制单元5发出指令去控制电子开关6，断开汽车远光灯供电，远光灯熄灭，当测得对方车辆开远 光灯时，本装置会发出闪动灯信号，提示对方关闭远光灯，LED指示灯4也相应发亮，向驾驶员提示当前汽车远光灯的现状，当有开着大灯的车迎面驶来，由探头1测的光亮信号传至控制单元5，经控制单元5判断后发出指令关断远光灯，而当车年检或其他原因时，不要此功能，可以连续操作原车远光灯开关，连续开/关五次以上后，本功能暂时取消，反之连续五次开/关以上后，本动能恢复，该项工作可采用编程的方法设计在控制单元5中，此为现有技术，故在此不做过多赘述，另外，可以通过编程的方法使控制单元5对感光元件8所测得的各种数据建立各种数据模型，为夜间行驶判断道路前方的各种情景：如前方车辆的远光灯、大灯、路边的大小反光牌、月圆月缺、阴天、雨天、上坡下坡等数据模型，这里的感光元件8可以为光敏三极管、光敏电阻和光敏二极管，另外，如图3中所示，实施例一中的控制单元5和感光元件8作为感光探头1可以在同一个空间，电源模块10和MOS三极管组件11组成的电子开关6在一个空间，探头1中的LED指示灯4是作为智能远光灯工作状态指示灯，同样实施例一也可以将控制单元5和感光元件8，电源模块10和MOS三极管组件11组成的电子开关6都作为感光探头1放置在一个空间，如图4中所示，另外，如图5中所示，实施例二中控制单元5和感光元件8作为探头1安装在一个空间，电源模块10和第一MOS三极管组件16组成左远光灯控制单元14，右远光灯控制单元15仅由第二MOS三极管组件17组成，探头1安装在驾驶室仪表台面上或驾驶员方便可视角度的任一位置，感光元件8正对汽车行驶的前方用以探测汽车正前方迎面来车的灯光，LED指示灯4对着驾驶员视线方向，该LED指示灯4用作提示被控制的远光灯是否开启和关闭。
需要强调这里的遮光套9的作用，光敏三极管作为感光元件8正对行驶 车辆的前方，当所驾车辆的远光灯打开后，前方50米内光线很强，这时感光元件8所测得的光信号几乎是自己远光灯的光亮，又因为远处200米以外的车灯亮度，远不如50米内的光亮度，所以没有遮光套9的感光元件8很难判断200米以外的车灯，若在感光元件8外套了一个同心圆的遮光套9，遮光套9的长度突出感光元件8感光平面5毫米以上，因遮光套9的遮挡，所驾车辆前方的光信号没有被感光元件8所测到，遮光套9越长，那么车辆前方被遮光线的距离就越长，但遮光套9太长就会引响感光元件8的感光灵敏度，所以本发明将遮光套9的长度定为5至15亳米；
对于实施例二中电路来说，当在夜间行车时，感光元件8正对车辆行驶的前方，当测得对面行驶车辆的灯光，感光元件8会发生变化，控制单元5通过测得感光元件8的变化输出高/低电压通过电阻R3,使MOS三极管Q3导通/截止，当MOS三极管Q3导通时，两个反相串联的PMOS管导通，当MOS三极管Q3截止时，两个反相串联的PMOS管断开，当电子开关6导通时LED指示灯4亮，反之LED指示灯4熄。

尽管已经示出和描述了本发明的实施例，对于本领域的普通技术人员而言，可以理解在不脱离本发明的原理和精神的情况下可以对这些实施例进行
