Abstract
A fail-safe control method for a hybrid electric vehicle is carried out based on a power transmission system of an engine, which is used to control the speed of the engine. When one of a plurality of motor-generators of the power transmission system malfunctions, the vehicle is controlled to be driven in a limp-home mode, thereby ensuring vehicle driving reliability and preventing the vehicle from becoming inoperable.
