Abstract
A light control device for vehicles that controls a light axis direction of a headlight in the vehicle has an inclination acquisition means that acquires a detection result of an inclination of the vehicle, and a light axis direction changing means that changes a direction of the light axis by a response modified by a predetermined filter, so that the light axis directions of the headlights approaches an angle beforehand set to align it with the road surface according to the acquired inclination of the vehicle.
Claims8
A light control device for vehicles that controls a light axis direction of a headlight in the vehicles comprising:
- an inclination acquisition means that acquires a detection result of an inclination of the vehicle;
- a light axis direction changing means that changes a direction of the light axis by a response modified by a predetermined filter, so that the light axis direction of the headlight approaches an angle beforehand set to align it with the road surface according to the acquired inclination of the vehicle;
- an operation acquisition means that acquires a detection result of a changing operation in which a driver of the vehicle performs a change of speed or acceleration of the vehicle;
- and
- a filter setting means that either selects a filter giving a better response or selects no filter as appropriate for giving the best response characteristics (responsiveness) according to a detection result of the changing operation by the driver of the vehicle.
