Abstract

In this paper, unmanned vehicle system and VFF algorithm development with vehicle dynamics is the main topic as a part of Intelligent Transportation System. Unmanned vehicle system is classified by vehicle system and control system. Authors used RC servo motor for longitudinal control via throttle angle, shift lever control, and brake control. For lateral control, authors used step motor, equipped with reduction gear. Unmanned vehicle has nine ultrasonic sensors in front of the unmanned vehicle. After the microcontroller computes the distance between unmanned vehicle and obstacle, the control computer calculates the steering angle enough to avoid the obstacle.

본 논문에서는 보다 빠른 속도의 무인주행과 이를 가능케하는 안전한 항법구현에 주력하여 시스템을 개발하고 알고리즘을 적용한 결과를 보이고 있다. 또한 본 논문에서는 9개의 초음파 센서를 사용하여 가상역장 알고리즘을 적용한 험로주행용 차량의 무인주행에 적용한 시스템의 구성과 적용방법을 기술하고 실차실험을 통한 시스템의 성능과 향후 연구방향을 제시하였다.
