Abstract:
1. A control apparatus of a vehicle lamp comprising: a reception section configured to receive acceleration vector information of a vehicle; a control section configured to obtain a tilt angle of the vehicle relative to a horizontal plane based on the received acceleration vector information and correct the obtained tilt angle of the vehicle based on correction information obtained from first pre-recorded reference acceleration vector of the vehicle being in a first state and second pre-recorded reference acceleration vector of the vehicle being in a second state different from the first state only in a pitch angle, and to determine an optical axis position of the vehicle lamp based on the corrected tilt angle; and a transmission section configured to transmit the determined optical axis position to an optical axis adjustment section, wherein each of the acceleration vector information, the first pre-recorded reference acceleration vector, and the second pre-recorded reference acceleration vector includes a gravity acceleration vector.
