AMT 성능 시뮬레이터 개발과 변속 특성 해석

This paper presents shifting characteristics of automated manual transmission(AMT). In order to analyze the shifting characteristics, an AMT simulator is developed by considering the clutch and shift actuator characteristics. Using the simulator, shifting performances such as clutch torque, acceleration and velocity are investigated. It is found that torque interruption occurs during the shifting, which results in negative acceleration. Shift and clutch actuator should be controlled precisely for improved shift quality.
