Zusammenfassung:	A method for an alternate control of a continuously variable valve duration (CVVD) malfunction may include a CVVD failsafe control to resolve a calculation error of a cylinder charge amount due to a hardware failure of a CVVD system with the cylinder charge amount determined by any one of flow rate alternate, flow rate deviation correction, and valve duration update if the hardware failure is recognized by a CVVD controller, and to apply the cylinder charge amount to secure an air amount for a combustion chamber.
