Abstract
A vehicle lamp controller, a vehicle lamp system having the vehicle controller, and a vehicle lamp control method are provided. The vehicle lamp controller includes a receiver configured to receive information on a detected vector from an output of an acceleration sensor, a memory in which a plurality of reference vectors are stored, the reference vectors corresponding to different pitch angles of a vehicle, a control unit configured to obtain a pitch angle of the vehicle from the detected vector and one of the reference vectors that has a smallest angle with respect to the detected vector, and to generate a control signal for adjusting an optical axis of a vehicle lamp based on the obtained pitch angle, and a transmitter configured to transmit the control signal to an optical axis adjustment portion of the vehicle lamp.
