Provided is an advanced 2-stage VVL operation learning control method applied to an electric 2-stage VVL system. According to the present invention, when driving a vehicle in EV mode, by performing the VVL operation learning for the secondary lift of an exhaust valve by the controller (10), which performs VVL control of the electric 2-stage VVL system (1), as an EV mode learning time securing control (S40-1) in which the engine is driven under the engine coolant temperature condition when a clutch of the engine and motor is disconnected, or HEV mode learning time securing control in which the engine is driven within the engine overrun time (S40-2), engine operation time is secured for VVL system fault diagnosis and avoidance area learning, just like other vehicles even in P2, P3, and P4 type hybrid vehicles that can apply EV mode.
본 발명의 전동식 2단 VVL 시스템에 적용된 어드밴스 2단 VVL 작동학습제어 방법은 전동식 2단 VVL 시스템(1)의 VVL 제어를 수행하는 리프트 컨트롤러(10)가 EV 모드의 차량주행 시 배기밸브의 2차 리프트에 대한 VVL 작동학습을 엔진과 모터의 클러치 분리 상태에서 엔진냉각수 온도 조건으로 엔진이 구동되는 EV 모드 학습시간확보제어(S40-1)로 수행하거나 또는 엔진 오버런 시간내에서 엔진이 구동되는 HEV 모드 학습시간확보제어(S40-2)로 수행됨으로써 EV 모드 적용이 가능한 P2,P3,P4 타입 하이브리드 차량에서도 기타 차량과 동일하게 VVL 시스템 고장진단 및 회피영역학습을 위한 엔진가동시간이 확보되는 특징을 갖는다.
