Abstract
A method for controlling an engine having a continuous variable valve duration (CVVD) apparatus is provided. The method includes: correcting a torque required by a driver; transmitting, by a hybrid control unit (HCU), a start signal to an engine control unit (ECU) when the corrected torque satisfies conditions required to drive the engine; determining a target CVVD value for operation of an intake CVVD apparatus corresponding to the corrected torque; determining a target current value corresponding to the target CVVD value; and changing the target CVVD value to a synchronizing CVVD value when a current state of the engine is in a cranking interval, wherein the synchronizing CVVD value is configured to synchronize starting revolutions per minute (RPM) of the engine with RPM of an automatic transmission or RPM of a motor generator.
