Control device mounted on vehicle and method for controlling the same

A vehicle comprising:

• a sensing unit configured to sense a topographical state of a road surface on which the vehicle is travelling;
• and
• at least one processor configured to:
• based on the topographical state of the road surface being a first topographical state, control a head lamp of the vehicle to be in a first output state that outputs light to a reference area ahead of the vehicle;
• and
• based on the topographical state of the road surface changing to a second topographical state different from the first topographical state, control the head lamp of the vehicle to change to a second output state that maintains the output of the light to the reference area ahead of the vehicle,
• wherein the at least one processor is further configured to:
• detect, through the sensing unit, a driving state of the vehicle;
• and
• control the head lamp of the vehicle to maintain the output of the light to the reference area ahead of the vehicle further based on a change in the driving state of the vehicle,
• wherein the change in a driving state of the vehicle corresponds to the vehicle approaching a zone in which an area of the light that is output from the head lamp on the road surface is changed by more than a threshold value, and
• wherein the at least one processor is further configured to control the head lamp of the vehicle to maintain the output of the light to the reference area ahead of the vehicle by:
• changing a light output direction of the head lamp prior to the vehicle reaching a predetermined distance from a start point of the zone, based on a change in the area of the light that is output from the head lamp on the road surface.

A method for controlling a vehicle, the method comprising:

• detecting a topographical state of a road surface on which a vehicle is travelling;
• based on the topographical state of the road surface being a first topographical state, controlling a head lamp of the vehicle to be in a first output state that emits light to a reference area ahead of the vehicle;
• and
• based on the topographical state of the road surface changing to a second topographical state different from the first topographical state, controlling the head lamp of the vehicle to change to a second output state that maintains the output of the light to the reference area ahead of the vehicle,
• wherein the method further comprises:
• detecting a surrounding area that is outside of a lane in which the vehicle is travelling,
• based on the surrounding area satisfying a first condition, controlling the head lamp to prevent the output of the light from reaching the surrounding area;
• and
• based on an object being detected in the surrounding area, controlling the head lamp to direct at least part of the light that is output from the head lamp to the detected object in the surrounding area.
