1. An intelligent idle stop and go (ISG) control device for a vehicle, the intelligent ISG control device comprising:
a signal detection unit configured to detect a plurality of signals comprising a signal indicating an engine revolution per minute (RPM) of the vehicle, a signal indicating a vehicle speed of the vehicle, a signal indicating a phase or variation in phase of an accelerator pedal of the vehicle, and a signal indicating manipulation of a brake pedal of the vehicle, and an ISG control unit configured to determine: whether an engine stop condition of the vehicle is satisfied; and whether an engine stop release condition of the vehicle is satisfied based on at least one signal of the plurality of signals detected by the signal detection unit, wherein the ISG control unit turns off an injector of an engine to stop the engine when the engine stop condition is satisfied, wherein the ISG control unit does not stop the engine when a predetermined first time has not elapsed since the engine was restarted in a vehicle moving state although the engine stop condition is satisfied.
