Abstract
A method for controlling a sudden unintended acceleration due to misoperation of an engine in a power split type hybrid electric vehicle (HEV) system, the method including when a determination is made that a delta revolution per minute (RPM) of an engine is out of a predetermined criterion, determining that an operating point of the engine does not move along a profile defined according to a target operating point of the engine and the sudden unintended acceleration is possible. The delta RPM is a difference of value between a current RPM of the engine and a profile RPM of the engine required to move to the target operating point of the engine from a current operating point of the engine.
