Abstract
본 논문은 스텝핑 모터를 이용하여 수동변속기 차량의 클러치를 자동으로 제어하기 위한 제어알고리즘 및 제어로직 구현 결과를 기술한 것이다. 기본제어 알고리즘은 차량의 통신데이터를 이용하여 운전자 의지를 파악하고 이에 따라 클러치 연결 혹은 해제 시점을 파악하여, 이에 따른 구동신호를 발생시키고 클러치의 위치 및 이동거리는 구동신호의 펄스 개수에 의하여 계산된다. 제어로직을 마이크로프로세서에 탑재하는 과정은 자동코드생성기법을 이용하였으며 이를 프로토 타입 제어기에 탑재하여 기본 성능시험을 실시하였다. This paper describes a control algorithm and test results of an automated manual transmission clutch actuated by a stepping motor. The control algorithm extracts driver's demand from CAN signals and decides the exact timing to engage or disengage the clutch based on the demand. A pulse signal is generated to drive the clutch and the travel of the clutch can be calculated by accumulating the pulse signal. An auto code generation method was introduced in implementing the control logic to the micro-processor of the prototype controller and a series of basic tests were carried out to validate its performance.
