클러치 슬립제어를 위한 제어 전략 방법에 대한 연구

This paper presents the slip control strategy of a torque converter clutch to improve fuel consumption. There are four kinds of simple method to control a clutch interface in an automatic transmission vehicles. One of them, the proposed slip control strategy introduces briefly the rule of control scheme. The other method simulates to investigate the fuel consumption of lockup clutch according to enlarge slip operating region. The faster lock up clutch engages in a low operating region and shifting gear, the better the fuel consumption of vehicle improves. Although simulation was carried out not to consider the vehicle dynamic performance and drivability, The result of simulation verify the fuel consumption improvement from each control strategy method.
