Abstract
A method of controlling an electric continuous variable valve timing apparatus improves starting performance of an engine by a simplified phase control for the camshaft. The method, in which intake and exhaust timing of an engine is changed in accordance with a phase of the camshaft, may include: determining whether starting off of the engine is required during driving; recognizing a target phase of the camshaft for next starting of the engine; controlling the phase of the camshaft so that the intake timing of the engine is advanced in accordance with the target phase; and ending the phase control of the camshaft in accordance with a state of the engine or the camshaft.
