摘要：
A method and system for controlling a low-voltage DC/DC converter (LDC) of a hybrid electric vehicle (HEV) includes performing a trial starting comprising steps of: trying ignition start, performing an immobilizer authentication process, and turning on a main relay of a high-voltage battery. The LDC is controlled after the trial starting, so that an operating voltage is applied from the LDC to an electric load including various kinds of controllers, thereby allowing starting of the HEV.
