Patent Images
1. An apparatus for controlling a head lamp, the apparatus comprising:
- a lamp electronic control unit for generating a lamp steering signal according to a received steering angle and speed information;
first and second head lamp control sections for generating motor driving signals corresponding to the lamp steering signal; and
first and second step actuators for rotating first and second head lamp modules at predetermined angles by converting a rotational movement of a motor into a linear movement according to the motor driving signals of the first and second head lamp control modules.
