Design and Experiment on the Intelligent Control System for External Vehicle Lamps

In view of the respective defects of existing manual and automatic operating devices of external vehicle lamps,the headlamp dimmer controlled combinatively by manual automatic complementary according to multi-information such as ambient sight distance,low-beam illuminated distance,stopping sight distance,braking,overtake,etc.was innovated and developed.To enhance more traffic security and vehicle control,the appending functions such as on-off lamps by manual automatic complementary,automatic turning on far beam rear fog lamps at quick speed-down,automatic turning on position front fog lamps at downfall,time-lapse illuminating at leaving the vehicle,illuminating at curved driving,failure warning at broken circuit,compensating light at emergency,self-reset combined switch,etc.were realized simultaneously.Taking a certain middle-class car as an experimental subject,the control arithmetic,the principle circuits and the function structures were carried out.The trial manufacturing,installing,debugging and long-term tryout of prototypes prove the feasibility,validity and wear of the system.
