| With the social progress and technological development, traffic safety has been higher andmore urgent demands, Therefore, the manufacturers of countries all over the world have con-centrated so much efforts on the intelligence research on automobile over the years. In orderto improve the safety driving at night, Based on the problems of traditional front-light systemwhich is can’t provide good lighting in time and bring dazzling to driver when the car passing.The research of automobile adaptive front-light system was the high valued.Automobile adaptive front-light system can provides the reasonable lighting beams accord-ing to the vehicle status and its environment, it can provide a good the best view for the driverand prevent traffic accidents. This paper considers the adjustment of front-light when the veh-icle driving on the corner, meet slope and the car body pitch at night,As well as intelligentcontrol aspects.This paper first study the current situation and development at home and abroad and thedevelopment trend of AFS, according to the correlative legal basis and the function require-ment to puts forward the design of the whole system solutions and choice more importantsensor which are used. Then the paper set up the the mathematical model of horizontaldeflection and the height adjustment of the adaptive front-light based on the vehicleparammeters, and with labview software to simulation analysis, the vehicle parameters andthe lights deflection angle of the quantitative relationship.The paper detailed study of the control strategy of AFS of Automotive uses the fuzzy con-trol theory,the AFS adopting the fuzzy control strategy, and compared with the traditionalwhich depends on precise mathematical model. the fuzzy control strategy can help to achieveeffective and more in line with of the intuitive control of the process of role descriptions. Thisconclusion laid the foundation for further research of AFS. |
