초록

본 논문은 자동차 윈드실드에 생기는 성에, 얼음, 눈 또는 잔해를 제거하는 워셔액 가열시스템의 성능 개선을 위한 새로운 제어 시스템을 제안한다. 먼저, 워셔액 가열시스템의 모델링 과정을 설명하고 실험결과를 이용하여 모델의 특성파라미터를 추출하고 워셔액 가열시스템 성능에 영향을 미치는 설계변수를 선정한다. 두 번째로 워셔액 가열시스템 가열 성능을 향상시키기 위하여 제어 시스템을 제안하였고 실험을 통하여 검증하였다. 제안된 제어시스템의 특징은 가열 성능을 충족하기 위하여 정의된 목표 값까지 WFHS에 인가되는 부스터 컨버터의 입력 전류를 조절하는 것이다. 목표 전류는 초기온도 조건과 함께 유도된 수학적 모델식을 이용하여 계산하였다. 컴퓨터 시뮬레이션과 실제 실험결과는 제안된 제어시스템이 WFHS의 기 설정한 목표성능을 만족시키면서 가열 동작을 수행 할 수 있다는 것을 보여준다.

This paper presents the design of a control system for improving performance of a washer fluid heating system (WFHS) which is capable of removing frost, ice, snow and/or other debris from windshield. First, for the WFHS, a modeling process is described, and the extraction of characteristic parameters of the model are made by experimental studies. Design variables that affect on performance of the WFHS are also presented. Secondly, a control system is proposed for improving heating performance of the WFHS, and its performance is verified through experiments. The key feature of the proposed control system is to regulate the current of a booster converter input to the WFHS up to the target value that is set to guarantee heating performance. Target current is calculated by using initial temperature value and employing the mathematical model derived in the paper. Computer simulation and experimental results show that the proposed control system can perform heating operations in a way to satisfy per-determined target performance of the WFHS.
