Method of controlling electric continuous variable valve timing apparatus
First Claim
1. A method of controlling an electric continuous variable valve timing apparatus, wherein intake and exhaust timing of an engine is changed in accordance with a phase of the camshaft, the method comprising:
- determining whether stop 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,wherein the phase of the camshaft is controlled to be always positioned further toward a direction in which the intake timing of the engine is advanced, than the target phase.

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.
