Abstract
A control apparatus of a vehicle lamp is provided with a reception section (LR), a control section (L,R) and a transmission section (LR). The reception section (LR) receives a tilt angle of a vehicle relative to a horizontal plane from a tilt detection device (). The control section (L,R) corrects the tilt angle obtained from the tilt detection device () based on correction information obtained from a first pre-recorded reference acceleration vector information (S) of the vehicle being in a first state and a second pre-recorded reference acceleration vector information (S) of the vehicle being in a second state different from the first state only in a pitch angle, and also determines an optical axis position of the vehicle lamp. The transmission section (LR) transmits the determined optical axis position to an optical axis adjustment section ().
