Abstract:
A vehicle lamp control apparatus includes a receiver, a storage, a correction section, and an adjustment instruction section. The receiver receives output values of an acceleration sensor. The storage stores information indicating an ideal positional relationship between sensor-side axes and vehicle-side axes. The correction section plots the output values, obtained during running of a vehicle, on coordinates in which acceleration in a vehicle longitudinal direction is set to a first axis and acceleration in a vehicle lateral/vertical direction is set to a second axis, derives a straight line from plotted points, calculates displacements of the sensor-side and vehicle-side axes from the ideal positional relationship, using an inclination of the straight line, and corrects the information. The adjustment instruction section derives a tilt angle of the vehicle from current acceleration using the corrected information, and generates a control signal to instruct adjustment of an optical axis of a vehicle lamp.
