A method can be used for controlling for engine running. An input unit receives required power data. A controller executes one among a first control for running an engine, a second control for keeping on running the engine, and a third control for stopping the engine, according to the required power data, to drive the engine. The battery is discharged or charged under control of the controller.

Method of controlling for engine running

A method for setting an electric vehicle (EV) on/off line of a hybrid vehicle considers a driving load of the vehicle by setting the EV on/off line based on a climbing angle and creep power. The method for setting the EV on/off line of the hybrid vehicle includes an operation of setting a region according to a state of charge (SOC), an EV online setting operation based on a climbing angle of the vehicle, and an EV offline setting operation based on creep power of the vehicle. The method provides a simple and intuitive EV line setting method to reduce a mapping time and substantially eliminate the possibility of human error, thus increasing logic reliability, so as to reduce use of a hybrid control unit (HCU) memory and provide cost-saving effects.
