PROBLEM TO BE SOLVED: To provide a continuous variable valve lift control method that can prevent decreasing fuel economy and a knocking phenomenon by efficiently decreasing an effective compression ratio even in an idle state of an engine.SOLUTION: A continuous variable valve lift control method includes the steps of: determining whether an engine is in an idle state and the oil temperature of the engine is within a set range; when the engine is in the idle state and the oil temperature is within the set range, controlling the engine to a predetermined adjustment state; when an error occurs in the adjustment state, measuring an error occurrence time, and when the error occurrence time exceeds a preset time, changing over the engine to a predetermined passive state to control the engine. |
