KR970020674A - Vehicle headlight control device and method - Google Patents

Abstract

The present invention comprises a first step of determining whether the automatic mode selection key, the speed measuring unit, the headlight driving unit, the control unit, and the power supply unit are configured to automatically operate the headlight of the vehicle; A second step of reading a speed signal output from a speed measuring unit for measuring a driving speed of the vehicle when the automatic mode is selected in the first step; A third step of determining whether the speed signal read in the second step is 0; A third embodiment of the present invention relates to a vehicle headlight control apparatus and method for performing the fourth step of turning off the headlight when the speed signal is zero and turning on the headlight when the speed signal is not zero. In the auto mode, the headlights are automatically turned off when the vehicle is stopped, and the headlights are automatically turned on when the vehicle is running. Therefore, it is possible to prevent the glare of the driver in front of the vehicle while waiting for the signal regardless of the driver's driving habits. There is an advantage to driving.
