A control system of a generator for a vehicle is provided to minimize fuel consumption through minimum power generation by performing operating condition to prevent battery charging rate from being more quickly reduced. A control system of a generator for a vehicle comprises a battery, a generator, a charge/discharge status detecting unit, a voltage detection unit, a temperature sensor, a driving condition detection unit, a regenerative voltage setting unit, and a power generation voltage setting unit. The battery has a discharging function and a charging function of supplying the electricity to an electrical load for a vehicle. With being driven with an engine and supplying the electricity to the electrical load, the generator charges the battery with electricity. The charge/discharge status detecting unit detects charge and discharge status from the current sensor detecting the charge and discharge current of the battery and the battery charge and discharge current. The voltage detection unit measures the voltage of the battery. The temperature sensor detects the temperature of the battery. The operation repayment detection unit detects vehicle drive situation. The regenerative voltage setting unit sets up regenerative voltage of the generator by synchronizing with fuel cut when the vehicle reduces speed according to the charge and discharge status and the temperature of the battery detected in the temperature sensor. The power generation voltage setting unit sets up the generating voltage of the generator in fuel injection.
