Route provision apparatus and route provision method therefor

A route provision apparatus for providing a route to a vehicle, the apparatus comprising:

• a transceiver configured to communicate with a server;
• a sensor interface configured to receive sensing information from one or more sensors disposed in the vehicle;
• and
• a processor configured to:
• identify a lane in which the vehicle is traveling among a plurality of lanes of a road based on an image received from an image sensor among the sensing information,
• estimate, using received map information for the vehicle in lane units based on the identified lane,
• generate autonomous driving visibility information by fusing the sensing information with the optimal route for transmission to the server and at least electric components disposed in the vehicle, and
• fuse dynamic information related to a movable object located along the optimal route with the autonomous driving visibility information to update the optimal path based on the dynamic information,
• wherein the map information is received from a navigation system provided at the vehicle and not from the server based on a communication state with the server satisfying a preset condition, and
• wherein the processor is further configured to fuse the sensing information received from the one or more sensors with the map information received from the navigation system to generate a Simultaneous Localization and Mapping (SLAM) map.
