PURPOSE: A restarting control system for an engine of ISG(Idle Stop and Go) vehicles is provided to prevent accidents by locking a restart of an engine while objects in front of the vehicles are detected through operation of a front sensor and a switch control. CONSTITUTION: A restarting control system for an engine of ISG vehicles comprises a hood opening recognition switch(111), a front sensor(112), a judgment unit(114), and a setting unit(115). If a car hood is opened, the hood opening recognition switch is automatically turned on and outputs hood opening recognition signals. The front sensor is installed at a front of the vehicles and outputs sense signals by detecting objects placed in front of the vehicles within a predetermined distance. The judgment unit confirms at least one input among the hood opening recognition signals and sense signals in a state that a car engine is switched off. If at least one among the hood opening recognition signals and the sense signals is inputted, the setting unit locks a restart of the engine.
