Abstract

In this paper, we developed a mid-range automotive radar systems based on the performance requirements and test procedures of the intelligent transport systems, that is lane change decision aid systems (LCDAS). The mid-range automotive radar has the maximum detection range up to 80m and an update time within 50ms. The computational loads of a signal processing were reduced by using ROI preprocessing technique. Considering actual driving environments, radar performance evaluations were conducted in two driving scenarios at an automotive proving ground.

본 논문은 ISO 17387규격에서 제공하고 있는 차선변경 보조시스템(LCDAS)에 기반을 둔 중단거리 차량용 레이더 시스템을 개발하였다. 사용한 규격에서는 지능형 이동 시스템에서 사용하고 있는 성능 요구사항과 시험 과정에 대해 기술되어 있다. 중단거리 차량용 레이더 시스템은 최대 80m까지 목표물을 검출할 수 있으며, 갱신주기는 50ms로 단축할 수 있도록 설계하였다. 또한, ROI 전처리 기술을 활용하여 신호처리에서의 계산량을 대폭 감소시킬 수 있었다. 최종적으로, 실제 운전 상황을 설정하여 실제 시험을 수행하였으며, 두 가지의 시나리오를 설정하여 성능을 평가했다.
