Abstract:
1. A vehicle lamp control apparatus comprising: a receiving portion adapted to receive output values of an acceleration sensor, a control portion adapted to derive a variation in an inclination angle of a vehicle based on the output values of the acceleration sensor and to generate a control signal for instructing an optical axis adjustment of a vehicle lamp, and a transmitting portion adapted to transmit the control signal to an optical axis adjusting portion of the vehicle lamp, wherein the control portion is adapted to detect an error factor of the output values occurring in the acceleration sensor based on the output values of the acceleration sensor and to correct an optical axis position of the vehicle lamp, wherein the receiving portion is adapted to receive a vehicle longitudinal direction acceleration and a vehicle vertical direction acceleration from the acceleration sensor, wherein the control portion is adapted to plot the output values of the acceleration sensor at least in one of an accelerating condition and a decelerating condition of the vehicle in a time series manner, on coordinates where the vehicle longitudinal direction acceleration is set on a first axis and the vehicle vertical direction acceleration is set on a second axis, so as to derive a straight line from at least two of plotted points, and wherein the control portion is adapted to determine the error factor based on a variation in a second axis intercept of the straight line.
