Intelligent halogen headlamp system and control method thereof

Abstract

The invention relates to an intelligent halogen headlight system. The intelligent halogen headlight system comprises dipped headlights with halogen bulbs, high beam lights, front fog lights, turn signal lights and an automatic control system. The automatic control system comprises a sensor set, a fog detector and a vehicle light control unit. A signal processing circuit of the vehicle light control unit receives vehicle running speed information, external environment illumination information, vehicle steering wheel turning angle information and external environment fog information, and converts all the received information into digital signals and outputs the digital signals to a microprocessor for processing. The microprocessor judges the obtained vehicle running speed V, an obtained illuminance value E, obtained vehicle steering wheel turning angles and external environment, and outputs control signals for a city mode, a turning mode, a road mode, a fog mode, a country mode and a highway mode correspondingly, so that the dipped headlights, the high beam lights, the front fog lights and the turn signal lights are driven in a constant-current mode to adjust light brightness. The intelligent halogen headlight system can improve road driving safety and driving comfort.

Description

technical field [0001] The invention relates to an intelligent halogen headlamp system and a control method thereof, belonging to the technical field of vehicle headlamps. Background technique [0002] Automobile headlights are lighting fixtures used to illuminate the road and identify obstacles ahead when the automobile is driving under severe weather conditions. Mainly used when driving at night. The car is equipped with headlights on both sides of the front part of the car body, which provides clear road condition lighting for the driver and prevents traffic accidents such as rear-end collisions and collisions. The current halogen headlights for vehicles have a single function and can only provide basic functions such as high beam function and low beam function, and the switch and switching of the headlights need to be manually operated by the driver, which is prone to misoperation; it is not humanized enough. It often happens that the lights are not turned on in time, ...
