Zusammenfassung:The present technology relates to a precision road map update system and a method for autonomous driving. According to an implementation example of an embodiment of the present invention, if an observation ratio among observed objects acquired while driving is less than a predetermined minimum observation ratio, the observed object is selected as a candidate for deletion, and then in accordance with whether the selected deletion candidate object has an observation history, a result of comparing the number of observations with a minimum number of observations, a result of comparison between an unobserved period and a minimum unobserved period, and a result of comparison between the number of trips in the unobserved period and the minimum number of trips, the deletion candidate objects are deleted and updated from a precision road map, thereby capable of preventing update errors of precision road maps in advance. Accordingly, the reliability and accuracy of precision road maps for autonomous driving can be fundamentally improved. The precision road map update system for autonomous driving includes a vehicle terminal and a map server. 본 기술은 자율 주행을 위한 정밀도로지도 갱신 시스템 및 방법에 관한 것으로, 본 실시예의 구현 예에 따르면, 주행 중 획득된 관측 객체 중 관측 비율이 기 정해진 최소 관측 비율 보다 작은 경우 관측 객체를 삭제 후보 객체로 선정한 다음 선정된 삭제 후보 객체의 관측 이력 존재 여부, 관측 횟수와 최소 관측 횟수와의 비교 결과, 미관측 기간과 최소 미관측 기간과의 비교 결과, 및 미관측 기간의 주행 횟수와 최소 주행 횟수의 비교 결과에 따라 삭제 후보 객체를 정밀도로지도에서 삭제 갱신함에 따라 정밀도로지도의 갱신 오류를 미연에 방지할 수 있고, 이에 자율 주행을 위한 정밀도로지도에 대한 신뢰성 및 정확성을 근본적으로 향상할 수 있다.
