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 inertia drive control is provided. The method includes performing advanced inertia drive control by an inertia drive controller. The controller detects a speed reduction event during road driving of a vehicle, lane division together with road type division for a road, and performs inertia drive control guide and the inertia drive control based on drive conditions of lane change and lane maintenance.

A method for controlling a coasting guide function is provided. The method may include: detecting a speed limit and an average speed of a peripheral vehicle; detecting a valid speed limit when a coasting event occurs; and calculating a target speed by using a speed factor computed by using at least one of the valid speed limit, the average speed of the peripheral vehicle, or a current speed.

Method for controlling coasting guide function

A coasting control method based on an overspeed response and an eco-friendly vehicle employing the same are provided. The coasting control method includes performing an active coasting control when an event for a section speed enforcement area is determined while a vehicle is traveling to allow the vehicle to pass through the section speed enforcement area based on a vehicle position at an event occurrence time.

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.
