A method of controlling a path providing device for a vehicle, where the method includes: receiving high-definition map data from a server; generating forward path information for the vehicle based on the high-definition map data; receiving, from sensors 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 driving operations of the vehicle. Generating the forward path information includes: based on a destination having been set for the vehicle, generating the forward path information to include a path to the destination; and based on the destination not having been set for the vehicle, generating the forward path information to include a path on which the vehicle is most likely to travel.
