PURPOSE: An ISG system and a control method thereof are provided to improve driving performance even if after restarting an engine right a way by maintaining the fluid pressure of an automatic transmission through an auxiliary pump. CONSTITUTION: An ISG system comprises an engine controller(10), an electronic steering unit, an automatic transmission controller, a brake controller, a cluster, and a battery control system. The engine controller controls engine operation based on whether to satisfy conditions for stopping or restarting an engine by receiving signals from each sensor of the battery control system, the cluster, the brake controller, and the automatic transmission controller. The cluster displays an ISG operation state transmitted from the engine controller, and transfers the signals on whether or not a hood, a door, and a seat belt is opened to the engine controller. The battery control system transmits the charge state of a battery to the engine controller.
