Abstract
The present disclosure provides a technology of determining an engine friction torque even when idling of an engine is not performed, by providing a certain engine Revolutions per Minute (RPM) in stop state of the engine using Hybrid Starter & Generator (HSG) connected to an engine pulley. The present disclosure provides a technology of determining an accurate engine friction torque using a torque provided from the outside of an engine instead of a torque generated the engine itself.
