1. An autonomous driving apparatus for a host vehicle, comprising:
an accident risk classification unit comprising a memory storing first program instructions and a first processor configured to:
classify roads around the host vehicle into respective groups depending on accident risks of the roads; and
generate for each of the roads, classification criteria determining application ratios of interpolation for generating precise map data or whether or not to store the precise map data, according to a distance from the host vehicle by executing the program instructions; and
an autonomous driving controller configured to:
transmit current position information of the host vehicle to an external apparatus using map data received from a navigation system;
generate and store the precise map data depending on the classification criteria; and
control the host vehicle based on the precise map data.
 
6. An autonomous driving system comprising:
an autonomous driving apparatus; and
an external apparatus comprising at least one of an accident database (DB) of a police agency or the accident DB of an insurance company, configured to receive current position information of a host vehicle provided with the autonomous driving apparatus mounted therein and to transmit an accident risk of a road corresponding to the current position information of the host vehicle to the autonomous driving apparatus;
wherein the autonomous driving apparatus comprises;
an accident risk classification unit configured to classify roads around the host vehicle into respective groups depending on accident risks of the roads and to generate, for each of the roads, classification criteria of determining application ratios of interpolation for generating precise map data or whether or not to store the precise map data according to a distance from the host vehicle; and
an autonomous driving controller configured to transmit current position information of the host vehicle to an external apparatus using map data received from a navigation system and to generate and store the precise map data depending on the classification criteria;
wherein the autonomous driving controller is further configured to control the host vehicle based on precise map data generated based on the accident risk.
