KR960000613A - Headlighter controller and control method of automobile - Google Patents

Abstract

The present invention detects the vehicle stop / movement, the brightness of the surrounding light and the brightness of the headlight of the opposite vehicle by using one motion sensor and two light sensors, and automatically turns on the switch of the headlighter according to the detection result. Provides a headlighter controller and control method that controls the headlighter to be automatically switched from upward to downward or upward by turning it on / off to prevent the risk of an accident caused by a manual switch of the headwriter to be manually operated. It is.
