Abstract

The invention relates to a method and an apparatus for controlling an engine system. The method of controlling an engine system may include: method of controlling an engine system including a continuous variable valve duration (CVVD) apparatus, the method including: detecting data for controlling the engine system; determining whether a speed of an engine is less than a predetermined speed; determining whether a position value of an accelerator pedal is greater than a predetermined position value when the rotation speed of the engine is less than the predetermined speed; operating the CVVD apparatus to increase a valve overlap when the position value of the accelerator pedal is greater than the predetermined position value; and performing a knock control after the valve overlap is increased.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2016-0169863 filed on December 13, 2016, the entire contents of which are incorporated herein by reference for all purposes. technical field [0003] The invention relates to a method and a device for controlling an engine system. More particularly, the present invention relates to a method and apparatus for controlling an engine system including a continuously variable valve duration (CVVD) device. Background technique [0004] An internal combustion engine generates power by burning fuel in a combustion chamber in a medium of air drawn into the combustion chamber. The intake valve is operated by the camshaft to draw in air, which is drawn into the combustion chamber while the intake valve is open. In addition, the exhaust valve is operated by the camshaft, and the combustion gas is expelled from the combustion chamber while the exhaust valve is ...
