Headlamp adaptive control method and device
2010
The invention discloses headlamp adaptive control method and device. The method comprises the steps of: (1) acquiring the current speed v of an automobile in real time, and acquiring the safe stopping distance S of the automobile at the current speed; (2) acquiring a horizontal deflection angle omega corresponding to the optimum lighting position of the headlamp; (3) acquiring a vertical deflection angle beta corresponding to the optimum lighting position of the headlamp; and (4) outputting control signals to control the turning of the headlamp in real time. The device comprises a control unit (1), and a detection unit (2) and a driving mechanism (3) which are respectively connected with the control unit (1), wherein the detection unit (2) comprises a speed sensor (21), a steering wheel angel sensor (22), a front ride height sensor (23), a rear ride height sensor (24), a sunshine and rain sensor (25) and an acceleration sensor (26). The invention has the advantages of large lighting range, good lighting effect, no reflected glare, simple structure, accurate control, good environmental suitability, safety, reliability and comfortable drive.
