1. A vehicle generation controlling system, comprising:

  • a battery supplying power to electric components of a vehicle;

    a generator generating power by using rotational force of an engine and supplying the generated power to the battery and the electric components; and

    an engine control unit (ECU) determining whether generation control is prevented by monitoring vehicle information on the vehicle and operational information on an operation of an electric product of a cooling system among the electric components and controlling the generator to prevent the generation control according to the determination;

    wherein the ECU monitors a battery temperature value sensed in the battery and performs the generation control to maintain fixed voltage without changing voltage by using the monitored battery temperature value to prevent the generation control; and

    wherein when the ECU determines that the generation control is prevented, the ECU stands by for a time as long as a predetermined set value of a delay time before preventing the generation control according to the determination.
