A method of determining an Idle Stop and Go (ISG) ventilation condition may include an ISG restriction early step that calculates an expected external air temperature through modeling using information acquired from a vehicle and execute an ISG logic to determine whether ISG entrance is possible based on a current ventilation condition of the vehicle, an ISG restriction proceeding step that detects an voltage of an air-conditioning system, an ISG restriction ascertaining step that determines whether an ISG entrance condition is satisfied, wherein the ISG entrance condition includes comparing the expected external air temperature through modeling with a specific temperature and the voltage of the air-conditioning system with a specific voltage, and an ISG entrance step that controls an engine by performing the ISG entrance when the ISG entrance condition is satisfied.

Ventilating condition determine method of idle stop and go function

A vehicle generation controlling system for saving fuel includes 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 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. As a result, the generation control is performed based on whether an electric product of a cooling system is actuated and vehicle information on the vehicle to thereby prevent cooling performance from being deteriorated due to the generation control.
