全电子汽车灯光检测器的研制

针对车辆行驶过程中不能及时发现车灯故障的问题,设计了一种新型全电子汽车灯光检测器。该检测器作为汽车制造过程中的固定电器件安装在汽车中央控制盒上,通过和车灯串联的分压电阻作为敏感元件来控制电路工作。介绍了该灯光检测器的工作原理、电路设计及性能。通过装车使用表明,该产品性能优良,且创下50万km无故障的记录。

The Development of Entire Electronic Automobile Light Detector

A new kind of entire electronic automobile light detector was designed according to the automobile light troubles that could not be found promptly during the driving process.As fixed electric part in the process of automobile manufacture,the detector was equipped on the central control box,and controlled the work of electric circuit as sense organ by the electric resistance connected in series with automobile light. The working principle, electric circuit design and performance of the detector were introduced in this paper.It is showed that the detector's performance is good,and has no troubles during 500 000 km vehicle running.
