자동차 엔진용 전자식 트로틀 밸브 시스템 개발 = Development of Electric Throttle Control System for Automobile Engines

다국어 초록 (Multilingual Abstract)

In this study, an electric throttle valve system for spark ignition engines is developed for the acceleration control of automobiles. The throttle valve system consists of a throttle valve, a small and high power D.C motor with a motor driver, and a cable reel system that connects the motor and the throttle valve. The motor driver is developed based on an H-bridge PWM(Pulse Width Modulation) circuit. The electric throttle valve system is controlled based on a simple propertional analog control circuit that utilizes the throttle valve position sensor information. It takes about 100msec. for the throttle valve to open from 0 to 90 degree, and the system has a bandwidth about 3 Hz, which is enough fast for a speed control or torque control of internal combustion engines for intelligent vehicle control applications.
