Optical axis control device for headlight of motorcycle

摘要: PROBLEM TO BE SOLVED: To stably insure the lighting range of a headlight even if banking angle, steering or like is changed, by providing control part correcting angle an optical axis through actuator, based on respective direction quantities. SOLUTION: Potentiometers 121, 122 are straight line type potentiometers, they provided suspensions front wheel and rear wheel, so as to detect stroke length. A 24 microcomputer housing controlling program, it searches for pitch quantity Dpy, Dbx, Dsz θb, θs, vehicle speed (v), detected potentiometers 122, angular velocity sensor 14, 16, 18, outputs pulse signals. Step motors 22x, 22y, 22z rotate normally reversely fixed angles according signals output from 24.
