The present invention relates to an autonomous driving method of a vehicle and an apparatus for the same. The autonomous driving method of the vehicle of the present invention comprises the following steps of: setting a driving destination and an arrival target time; searching for routes which can reach the destination; generating an expected average driving speed profile for each searched route; assigning a rank according to a fuel consumption amount of the vehicle to each of the routes; extracting a route satisfying the target time from among the routes; selecting a highest-ranked route among the extracted routes; dividing a section of the selected route and distributing a required time to each section; and driving the vehicle along the selected route to minimize fuel consumption within a range which satisfies the required time for each section. An objective of the present invention is to provide the autonomous driving method of the vehicle, capable of improving fuel efficiency by minimizing energy consumption as much as possible, and the apparatus for the same.
