Path providing device and control method thereof

A path providing device configured to provide a path for a vehicle, the device comprising:

• a telecommunication unit;
• an interface unit;
• at least one processor;
• and
• at least one computer memory operably connectable to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:
• receiving, through the telecommunication unit, high-definition map data from a server,
• generating forward path information for the vehicle based on the high-definition map data,
• receiving, through the interface unit from at least one sensor provided in the vehicle, sensing information related to an object outside the vehicle, and
• determining a validity of the object based on the forward path information,
• wherein the validity of the object relates to whether the object is likely to affect one or more driving operations of the vehicle,
• wherein generating the forward path information comprises:
• based on a destination having been set for the vehicle, generating, based on the high-definition map data, the forward path information to comprise a path to the destination, and
• based on the destination not having been set for the vehicle, generating, based on the high-definition map data, the forward path information to comprise a path on which the vehicle is most likely to travel,
• wherein determining the validity of the object comprises:
• classifying a plurality of roads, which are located within a predetermined range from the vehicle, into a first group and a second group, based on the forward path information, and
• wherein the operations further comprise:
• classifying, into the first group, (i) a main road, among the plurality of roads, that corresponds to the forward path information, and (ii) a sub road, among the plurality of roads, through which another vehicle is allowed to enter the main road, and
• classifying, into the second group, remaining roads, among the plurality of roads, except for the main road and the sub road,
• determining the object to be invalid based on the object being located on a road of the second group,
• adjusting a detectable range of the at least one sensor such that the at least one sensor senses the road included in the first group and does not sense the road included in the second group, and
• controlling the at least one sensor not to sense the object that is determined to be invalid.
