Description

一种智能远光灯控制系统 技术领域
本发明涉及汽车灯光智能开关技术，尤其是远光灯智能开关。
 背景技术
夜间行车远光灯操作不当是造成汽车事故的主要原因之一，据统计此类事故可占汽车总事故的35%。对于现有汽车而言，前灯智能控制已经广泛应用，其主要原理是利用感光元件检测车辆周围环境光，根据环境光强弱自动开启或关闭汽车前灯。但通过光敏元件无法自动控制远光灯，在夜晚汽车交互时，会车双方都应该关闭远光灯，但车辆本身开启远光灯后，车辆前方10米环境光可达0.9Lux，已将迎面10米-100米环境光强度覆盖，通过感光元件无法得知迎面车辆是否开启车灯。目前远光灯探头传感器有多种形式：如光学成像AI系统、激光雷达和毫米波雷达测距系统以及采用光敏三极管的控制系统。前两种探头器由于体积大，能耗高及硬件过于复杂，成本太高，控制效果且不够人性化。后一探头传感器采用光敏三极管，成本低体积小，并且独特的结构设计组成的远光灯控制更人性化，适用于汽车大规模应用。
OBD II接口为汽车标准的诊断接口，是通过标准的CAN总线和K线协议与汽车电脑BCM通讯的接口。通过该接口可以发出控制汽车各种灯光的开和关的指令。由于OBD II接口本身就具有通讯和供电模组，如果将光敏三极管的控制系统通过OBD II接口与汽车控制系统相连，就可以达到直接通过探头控制车辆远光灯自动开闭的效果。

本申请中感光元件是一只光敏三极管，或者是光敏电阻、光敏二极管，使用光敏三极管效果更好，并在其外套设有遮光套，遮光套是空心管结构，光敏三极管设置在空心管内，空心管长度略突出光敏三极管感光面一小段长度，因为光是直线传播，没有空心管则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从而造成结果失真。空心管的光敏三极管因感光面被管子突出部份遮档了离光敏三极管较近的光线，这样探测到本车所发出的远光灯光线会大大减弱，只会对对面行驶的灯光敏感，此时才能良好的判断对面是否开启远光灯。远光灯控制系统工作过程为：汽车原车远光灯开关断开后，本装置开始工作，当探头组件检测到光线较暗，即车辆正前方无任何车大灯亮也没有迎面而来的汽车，由控制器判断后通过连接器发出接通指令，并让汽车组合灯开关中的远光灯闭合，使得汽车远光灯接通。当有开着大灯的车迎面驶来，由探头组件测的光亮信号传至控制器，然后向发出指令关闭远光灯。
本申请远光灯控制系统控制汽车远光灯的连接方式并不影响驾驶员通过原车前灯控制开关控制远光灯，通过OBD II接口让远光灯控制系统与汽车控制系统相连，并且原车人工控制手段和本申请远光灯控制系统并不冲突，加装远光灯控制系统后无论是否开启远光灯控制系统都不影响驾驶员手动控制远光灯，当无需本装置时也可以快速进行拆装。
本系统控制器有一组与汽车对接的标准接口，本发明使用CAN-H、CAN-L、+12V及地线（搭铁）。控制器内有变压模块将12V变为3.3V，为控制盒内控制模块、CAN总线通讯模块供电，同时也为外接的探头组件提供电源。控制模块控制CAN总线通讯模块，使其通过CAN-H与CAN-L通讯线与汽车电脑通讯，控制汽车各照明灯。控制器还有4P接口，该接口与探头组件的4P接口相连。四个线分别是+3.3V、地线、及两个串口通信线。既整个远光灯控制系统的供电由OBD II接口直接提供，且也由OBD II接口与汽车控制电脑进行通讯。由于OBD II接口现在主要应用于汽车维修时的信息输出，因此在汽车正常使用时OBD II接口空置，使得本申请远光灯控制系统在汽车正常使用时占用OBD II接口，如果OBD II接口需要其他硬件接入，可直接将本系统从OBD II接口上拔出。
本发明还使用CAN-H、CAN-L、+24V及地线（搭铁）。控制器内有变压模块将24V变为5V或3.3V。还可以使用OBD II接口为行车记录仪供电，再由行车记录仪为远光灯控制系统供电，这种结构中远光灯控制系统集成在行车记录仪内，行车记录仪通过OBD II接口与汽车通讯。
在本申请中通过OBD II接口让本远光灯控制系统与汽车控制系统相连，也可以变成通过USB接口让本远光灯控制系统与汽车控制系统相连。通过USB接口相连时，变压模块的工作逻辑发生改变。
另一方面本申请还具有软件升级系统，软件升级主要与汽车软件升级相适应，如果汽车进行软件升级，或不同车型其对远光灯的控制和判断逻辑发生改变，则本系统需要相近的软件升级进行系统适配，升级的方式包括无线通讯、蓝牙通讯、烧录、插卡的一种或多种，本升级系统可以集成在OBD II接口内、控制器内或行车记录仪内。
更进一步的，本申请中探头组件和控制器分别设置，其中探头组件集成在行车记录仪中，由行车记录仪对探头组件进行供电。控制器通过OBD II接口或USB接口连接车载系统，探头组件和控制器通过wifi或蓝牙或其他无线通讯手段通讯进行数据传输，从而进行远光灯的自适应控制。
与现有技术相比，通过本远光灯控制系统可以根据环境光以及相对行驶车辆状态自动控制远光灯的开闭，并且本系统通过OBD II接口与汽车控制系统相连，无需额外信号转换以及供电设备，结构简单。成本低廉。

 具体实施方式
以下将结合附图对本发明各实施例的技术方案进行清楚、完整的描述，显然，所描述的实施例仅仅是本发明的一部分实施例，而不是全部实施例。基于本发明中所述的实施例，本领域普通技术人员在不需要创造性劳动的前提下所得到的所有其它实施例，都在本发明所保护的范围内。
如图1和图2所示，实施例1：一种智能远光灯控制系统，包括探头组件2和控制器1，所述的控制器1包括CAN总线通讯模块、控制模块、变压模块和OBD II接头3，所述的探头组件2包括感光元件、探头控制器、指示模块和开关。所述的指示模块可以是LED警示灯。
所述感光元件包括遮光套和设置在遮光套内的光敏三极管，所述探头控制器将光信号转换为电信号。所述的控制器1和所述的探头组件2上还设置有四芯接口4，所述的控制器1和所述的探头组件2通过四芯线连接。所述的四芯线包括串口通讯线、供电线以及地线。所述的变压模块将12V电压或24V降压至3.3V。所述探头组件2正对汽车行驶方向。
控制器1通过OBD II接头3与汽车连接，并与汽车中控电脑通讯。控制器1和探头组件2由汽车供电，由于汽车供电电压为12v或24V，则通过变压模块将12v或24V电压降压至3.3v为CAN总线通讯模块、控制模块和探头控制器供电。本申请远光灯控制系统使用过程为：汽车点火后，探头组件2供电并开始工作，此时可以通过开关关闭探头组件2。 根据汽车行驶环境路况，探头组件2经串口通信发出汽车远/近光的指令给控制器1，控制器1将其转换为CAN线通讯信号，通过OBD II接口3发送至汽车电脑控制远/近光灯的开和关，此时LED警示灯闪烁，提醒驾驶员远/近光灯开或关。汽车熄火后探头组件2没有供电，停止工作。
OBD II接头3内还包括软件升级模块，软件升级模块内设置有WiFi模块或蓝牙模块，通过WiFi模块或蓝牙模块进行外部通讯，在必要的时候进行软件更新。
实施例2：一种智能远光灯控制系统，包括探头组件和控制器，所述的控制器包括CAN总线通讯模块、控制模块、变压模块和OBD II接头，所述的探头组件包括感光元件、探头控制器、指示模块和开关。所述的指示模块可以是LED警示灯。所述探头组件正对汽车行驶方向。
所述控制器与所述探头组件无线通讯，控制器通过wifi和蓝牙的方式与探头组件无线通讯。
所述感光元件包括遮光套和设置在遮光套内的光敏三极管，所述探头控制器将光信号转换为电信号。所述的控制器和所述的探头组件上还设置有四芯接口，所述的控制器和所述的探头组件通过四芯线连接。所述的四芯线包括串口通讯线、供电线以及地线。所述的变压模块将12V电压或24V降压至3.3V。所述探头组件正对汽车行驶方向。
控制器通过OBD II接头与汽车连接，并与汽车中控电脑通讯。控制器由汽车供电。探头组件外置或探头组件设置在行车记录仪内，探头组件额外供电或由行车记录仪供电。
本申请远光灯控制系统使用过程为：汽车点火后，探头组件供电并开始工作，此时可以通过开关关闭探头组件。 根据汽车行驶环境路况，探头组件经串口通信发出汽车远/近光的指令给控制器，控制器将其转换为CAN线通讯信号，通过OBD II接口发送至汽车电脑控制远/近光灯的开和关，此时LED警示灯闪烁，提醒驾驶员远/近光灯开或关。汽车熄火后探头组件没有供电，停止工作。
探头组件内还包括软件升级模块，软件升级模块内设置有WiFi模块或蓝牙模块，通过WiFi模块或蓝牙模块进行外部通讯，在必要的时候进行软件更新。
实施例3：一种智能远光灯控制系统，包括探头组件和控制器，所述的控制器包括CAN总线通讯模块、控制模块、变压模块和OBD II接头，所述的探头组件包括感光元件、探头控制器、指示模块和开关。所述的指示模块可以是LED警示灯。
智能远光灯控制系统可集成在行车记录仪内。
所述感光元件包括遮光套和设置在遮光套内的光敏三极管，所述探头控制器将光信号转换为电信号。所述的控制器和所述的探头组件上还设置有四芯接口，所述的控制器和所述的探头组件通过四芯线连接。所述的四芯线包括串口通讯线、供电线以及地线。所述的变压模块将12V或24V电压降压至5V为行车记录仪供电。所述探头组件正对汽车行驶方向。
行车记录仪通过OBD II接头与汽车连接，并与汽车中控电脑通讯。
在本模式中，行车记录仪集成的远光灯自动控制系统，能判断车辆启动与否，若车辆在启动状态，则OBD II输出12V或24V电压且将电压降至5V供行车记录仪使用，同时将12V或24V电压降至3.3V供远光灯自动控制系统使用。若判断车辆是在熄火状态，则设备进入待机状态，不输出相应工作电压，使该行车记录仪进入待机状态，仅完成缩时录影功能。
行车记录仪内还包括软件升级模块，软件升级模块内设置有WiFi模块或蓝牙模块、SD卡模块、烧录模块等，通过WiFi模块或蓝牙模块或SD卡模块或烧录模块进行外部通讯，在需要的时候进行软件更新。
