실시간 차량 시뮬레이터의 개발

Driving simulators are used effectively for human factor study, vehicle system development and other purposes by enabling to reproduce actual driving conditions in a safe and tightly controlled environment. This paper describes a driving simulator developed for design and evaluation of a full-scale driving simulator and for driver-vehicle interaction study. The simulator consists of a real-time vehicle simulation system, a visual and audio system, a motion system, a control force loading system, and an experiment console. The real-time vehicle simulation system supervises overall operation of the simulator and also simulates dynamic motion of a multibody vehicle model in real-time. The economical visual system generates high fidelity visual scenes that are displayed on a screen by a projector. The motion system generates realistic motion cues using a six degree of freedom Stewart platform driven hydraulically. The control force loading system acts as an interface between a driver and the simulator. The experiment console monitors the status of the simulator in operation and also collects and manages experimental data.
