First Claim
Patent Images
1. A control apparatus for a vehicle lamp, the control apparatus comprising:
- a receiver to receive an acceleration signal indicative of an acceleration detected by an acceleration sensor; and
a controller to derive an inclination angle of a vehicle relative to a horizontal plane from the acceleration signal,wherein, while the vehicle is stopped and if a change in the acceleration exceeds a threshold, the controller outputs an adjustment signal indicative of an instruction to adjust an optical axis of the vehicle lamp in accordance with a difference in the inclination angle before and after the change in the acceleration.

Abstract
A control apparatus for a vehicle lamp includes a receiver to receive an acceleration signal indicative of an acceleration detected by an acceleration sensor, and a controller to derive an inclination angle of a vehicle relative to a horizontal plane from the acceleration signal. While the vehicle is stopped and if a change in the acceleration exceeds a threshold, the controller outputs an adjustment signal indicative of an instruction to adjust an optical axis of the vehicle lamp in accordance with a difference in the inclination angle before and after the change in the acceleration.
