1. A system for generating an autonomous driving path using harsh environment information of an high definition map, comprising:
a search extension determination unit including a data storage unit for storing data having high definition map data and autonomous vehicle information as data used for autonomous driving, and a search extension module that performs network search extension processing in the direction of tracking a road with a low search cost and avoiding harsh environment conditions;
a search information generation unit for generating search extension information according to the performance of the search extension module; and
a search result generation unit configured to generate an autonomous driving path based on the search extension information,
wherein when the harsh environment conditions exist on the road of the extended network: identify one or more alternative roads that avoid the harsh environment conditions, calculate respective search costs for the alternative roads, and extend the network along a road with lowest search cost of the alternative roads.
