Abstract

이 발명은 5속 자동변속기의 스킵 시프트(SKIP SHIFT) 제어장치 및 방법에 관한 것으로, 종래의 4속 자동변속기를 사용하였을 경우 거기에는 스킵 시프트가 존재하지 않기 때문에 운전자가 주행중인 변속을 할 경우 필요없이 변속쇼크를 느끼는 경우가 많이 있어 주행상의 불안정성을 가져오는 단점이 발생하는 것을 해결하기 위하여, 자동변속기의 변속 제어장치내에 스킵 시프트 기능을 부여하여 운전자가 주행중에 느끼는 불필요한 변속 쇼트의 충격을 덜을 수 있을 뿐만 아니라, 가속성능을 향상시킬 수 있고, 또한 배터리 전압을 체크하여 낮은 전압일 경우 변속을 실시하지 않아서 자동변속 구조상 가장 안전한 3단을 계속 유지하켜 주므로 주행 안전성을 향상시킬 수 있는 5속 자동변속기의 스킵 시프트(SKIP SHIFT) 제어장치 및 방법에 관한 것이다.The present invention relates to a skip shift control device and a method of a five-speed automatic transmission. When a conventional four-speed automatic transmission is used, there is no skip shift there, so it is necessary when the driver shifts while driving. In order to solve the shortcomings that cause the instability of the driving because there are many cases of shift shock without feeling, the skip shift function is provided in the shift control device of the automatic transmission to reduce the impact of the unnecessary shift short that the driver feels while driving. Not only can it improve acceleration performance, but it also checks the battery voltage and does not shift when the voltage is low, so it keeps the 3rd safest in the automatic transmission structure, so it can improve driving safety. The present invention relates to a skip shift control device and a method of a transmission.
