Abstract

This paper describes a recursive least-squares based convergent algorithm for driving characteristic classification for personalized autonomous driving. Recently, various researches on autonomous driving technology have been conducted for level 4 fully autonomous driving. In order for commercialization of the autonomous vehicle, personalized autonomous driving is required to minimize passenger's insecureness to the autonomous vehicle. To address this problem. this study proposes mathematical model that represents driving characteristics and recursive least-squares based algorithm that can estimate the defined characteristics. The actual data of two drivers has been used to derive driving characteristics and the hypothesis testing method has been used to classify two drivers. It is shown that the proposed algorithms can derive driving characteristics and classify two drivers reasonably.

본 논문은 자율주행 개인화를 위한 순환 최소자승 기반 융합형 종방향 주행특성 구분 알고리즘에 관한 연구이다. 최근 자율주행 기술은 Level 4 완전 자율주행 단계를 위해 다양한 연구가 수행되고 있다. 자율주행 자동차의 상용화를 위해서는 탑승자의 자율주행에 대한 이질감을 최소화할 수 있어야 하며 이를 위해 자율주행 개인화 기술이 필요하다. 이 문제를 해결하기 위해 본 연구에서는 운전자의 종방향 주행특성을 수학적으로 표현하고 순환 최소자승 기법 기반 실 주행 데이터를 이용하여 주행특성을 도출하는 알고리즘을 제안하였다. 두 명의 실제 운전자 데이터를 이용하여 종방향 주행특성을 도출하였으며 두 명의 운전자를 구분하기 위해 가설검정 기반 확률적 구분 알고리즘을 적용하였다. 제안된 종방향 주행특성 도출 및 구분 알고리즘은 개별 운전자의 주행특성을 합리적으로 나타낼 수 있었으며 가설검정 기반 확률적 구분기법에 의해 주행특성이 구분될 수 있음을 확인하였다.
