Control device for vehicle lamp, vehicle lamp, and method of controlling vehicle lamp

摘要

There is provided a control device for controlling a vehicle lamp provided in a vehicle. The device includes: a receiver configured to receive an inclination angle of the vehicle with respect to a horizontal plane from an inclination detector; a controller configured to: i) generate a first control signal instructing the vehicle lamp to adjust an optical axis of the vehicle lamp in response to a change of the inclination angle, when the vehicle has already stopped; and ii) generate a second control signal instructing the vehicle lamp to maintain the optical axis of the vehicle lamp, when the vehicle is traveling on a road surface; and a transmitter configured to transmit the first control signal or the second control signal to an optical axis adjuster provided in the vehicle lamp.

1. A control device for controlling a vehicle lamp provided in a vehicle, the device comprising:
a receiver configured to receive an inclination angle of the vehicle with respect to a horizontal plane from an inclination detector; a controller configured to: i) generate a first control signal instructing the vehicle lamp to adjust an optical axis of the vehicle lamp in response to a change of the inclination angle, when the vehicle has already stopped; and ii) generate a second control signal instructing the vehicle lamp to maintain the optical axis of the vehicle lamp, when the vehicle is traveling on a road surface; and a transmitter configured to transmit the first control signal or the second control signal to an optical axis adjuster provided in the vehicle lamp; wherein the inclination angle comprises: a first angle that represents an inclination angle of the road surface with respect to the horizontal plane; and a second angle that represents an inclination angle of the vehicle with respect to the road surface, wherein the controller is configured to record a first reference angle of the first angle and a second reference angle of the second angle, wherein the first reference angle is obtained based on the second reference angle and the inclination angle received from the inclination detector when the vehicle is about to stop, and wherein when the inclination angle is changed in a case where the vehicle has already stopped, the controller determines the optical axis based on the second angle that is obtained based on the first reference angle and the inclination angle received from the inclination detector, and the controller records the obtained second angle as a new second reference angle.
