Autonomous Driving Device and Driving Control Method Thereof

An autonomous driving device and a driving control method thereof are provided. The autonomous driving device includes at least one sensor, a processor, and storage including a database. The processor is configured to detect, using the at least one sensor, an obstacle that is present on a passage in a first driving path, of the first autonomous driving device, to a destination; determine whether there is a need for the first autonomous driving device to cross paths with the obstacle to pass through the passage; determine a time to collision by the first autonomous driving device with the obstacle; determine whether the obstacle is a second autonomous driving device; identify a driving rule corresponding to the second autonomous driving device; determine, based on the driving rule, a second driving path for passing through the passage; and control the first autonomous driving device to drive on the passage along the second driving path.
