摘要
A method of two-step variable valve lift (VVL) operation learning control for a vehicle may include: applying, by a lift controller, a VVL control to an electric two-step VVL system; determining, by the lift controller, whether the vehicle is running in an electric vehicle (EV) mode; and when the vehicle is running in the EV mode, performing, by the lift controller, a learning time securing control of allowing a VVL operation learning to be performed by engine operating for an operation avoidance area and an operation avoidance time which are applied to a secondary lift of an exhaust valve.
