Abstract

A semi-automatic clutch was developed for drivers of vehicles with manual transmission. The clutch is operated by pressing a switch on the gear stick without stepping on a clutch pedal when the driver wants to shift gears. To automatic control a clutch, driving information is provided by sensors installed under the vehicle. On the other hand, sensors are prone to failure under severe driving conditions and a long time is needed to install or repair these sensors in the vehicle. In this paper, a semi-automatic clutch that received driving information by CAN communication from the ECU was developed and a pneumatic actuator was used to operate the clutch. The semi-automatic clutch by a pneumatic cylinder was operated with a supply air pressure of more than 3bar.

전북 익산시 R회사에서 기 개발된 세미오토 클러치는 수동클러치 차량의 기어 변속시 클러치 페달을 밟아야하는 불편함을 해소하고자 만들어진 장치로써 클러치 페달을 밟지 않고, 운전자가 기어봉에 위치한 스위치 조작만으로도 클러치 동작을 제어할 수 있다. 차량의 변속과정에서 클러치 동작을 제어하기 위해 센서를 설치하여 차량정보를 수집하여 제어하였다. 그러나, 센서 기반의 제어기는 열악한 운전조건에서 고장 원인이 되고 있으며, 차량에 설치하고 보수하는 과정에서 시간소요가 과다하여 많은 불편을 가지고 있었다. 이를 위해 본 연구에서는 차량의 ECU와 CAN통신을 통해 차량의 주행정보를 수집하여 제어하고, 공압 액추에이터로 클러치를 동작시키는 세미오토 클러치를 개발하였다. 개발된 공압 액추에이터의 정상적인 동작을 위해서는 최소 3bar이상이 요구되었다.
