Autonomous vehicle system and path decision method for the same

PURPOSE: An autonomous driving system for an autonomous vehicle and a drivable route generating method using the same are provided to reduce a load of a CPU in an SBC(Single Board Computer) and autonomously drive a vehicle on a paved road, an unpaved road, and plains at high speed by reducing calculation amounts. CONSTITUTION: An autonomous driving system includes a multi-scan radar(110), a calculation unit(120), and an autonomous driving processing device(130). The multi-scan radar collects distance data from a target point by irradiating a laser in first and second routes with different orientation angles from a horizontal plane. The calculation unit determines a drivable region by calculating the slope of the target point based on the orientation angles and the distance data and calculates a drivable route from boundary values of the drivable region. The autonomous driving processing device controls the autonomous movement of the vehicle based on the drivable route.
