Abstract:
To provide a technique capable of accurately obtaining the attitude of a vehicle in the pitch direction. A control device for a vehicular lamp which controls the optical axis of a vehicular lamp in accordance with an attitude change in pitch direction of the vehicle is disclosed. The device includes an angle calculation part which obtains a first and a second acceleration by eliminating the gravitational acceleration component from each acceleration in the vertical and the longitudinal direction of the vehicle, calculates a vehicle traveling direction acceleration based on the accelerations, and obtains a vehicle attitude angle based on the correlation between the vehicle traveling direction acceleration and the first and the second accelerations. The angle calculation part obtains the attitude angle of the vehicle when it determines that the vehicle is accelerating or decelerating based on the determination on the basis of each acceleration difference at the predetermined time.

Claim (Index 1):
A control device for a vehicular lamp which variably controls optical axis of the vehicular lamp in accordance with an attitude change in the pitch direction of a vehicle comprising:\n an angle calculation part, wherein the angle calculation part obtains acceleration values each associated with the vertical direction and the horizontal direction of the vehicle at a predetermined time interval, and obtains a first acceleration value related to the vertical direction of the vehicle and a second acceleration value related to the horizontal direction of the vehicle by eliminating gravitational acceleration component from each of the acceleration values, wherein the angle calculation part calculates a vehicle traveling direction acceleration based on the first acceleration value and the second acceleration value, and further obtains an attitude angle of the vehicle based on a correlation between either one of the first acceleration value or the second acceleration value and the vehicle traveling direction acceleration, and an optical axis setting part which generates a control signal for controlling the optical axis of the vehicular lamp based on the attitude angle of the vehicle obtained by the angle calculation part, and provides the control signal to the vehicular lamp, and wherein, before obtaining the attitude angle of the vehicle, the angle calculation part performs a first determination process that determines whether or not the vehicle is accelerating or decelerating by comparing either (i) the amount of change in one of each of the acceleration values at the predetermined time, (ii) the amount of change in the combined value of each of the acceleration values at the predetermined time, or (iii) the amount of change in the value obtained by eliminating the combined value of the gravitational acceleration component from the combined value of each of the acceleration values at a predetermined time, with a reference value corresponding to the selected amount of change, and obtains an attitude angle of the vehicle when the angle calculation part determines that the vehicle is accelerating or decelerating based on the first determination process.
