AUTONOMOUS DRIVING SYSTEM

An autonomous driving system (100) including: a path planning unit configured to plan a path by a path planning model (13a) based on a detection result of an on-vehicle sensor (3) of a vehicle and map information; a reference path calculation unit (14) configured to calculate a reference path; an influence degree calculation unit (15) configured to calculate an influence degree with which a periphery of the vehicle is influenced by autonomous traveling of the vehicle along the planned path based on a comparison result between the planned path and the reference path; a threshold value calculation unit (16) configured to calculate an influence degree threshold value which is a threshold value of the influence degree based on a peripheral situation of the vehicle; and a notification controller (17) configured to issue a notification to an occupant of the vehicle when the influence degree is equal to or greater than the influence degree threshold value.
