US 2013/0211656 A1 · AUTONOMOUS DRIVING APPARATUS AND METHOD FOR VEHICLE

Abstract

Disclosed herein are an autonomous driving apparatus and method for a vehicle. The autonomous driving apparatus includes an autonomous driving context data processing unit, a simulator unit, a section determination unit, a path planning unit, and a context determination main control unit. The autonomous driving context data processing unit gathers autonomous driving context data. The simulator unit simulates autonomous driving based on the gathered autonomous driving context data. The section determination unit determines a reliable section or an unreliable section based on results of the simulation. The path planning unit searches for at least one global path to a set destination based on results of the determination, and searches the at least one global path for a local path along which the autonomous driving is possible. The context determination main control unit controls the autonomous driving of the vehicle along the local path.

Dependent claims

An autonomous driving method for a vehicle, comprising:

obtaining a current position of the vehicle and setting a destination of the vehicle;
searching paths, ranging from the current position of the vehicle to the destination, for an autonomous driving global path having a reliable section;
periodically obtaining a position of the vehicle moving along the autonomous driving global path;
if the obtained position falls within a set error range, determining whether the vehicle has reached the destination based on results of matching the position of the vehicle with a map;
if, as a result of the determination, it is determined that the vehicle has not reached the destination, obtaining a current link and a subsequent link of the vehicle and determining whether the subsequent link corresponds to the reliable section;
and
if, as a result of the determination, it is determined that the subsequent link is the reliable section, controlling driving of the vehicle so that the vehicle is moved by autonomous driving.
