Abstract
A method for monitoring a torque in a hybrid electric vehicle includes calculating an output torque of a motor based on a discharging power of a high voltage battery, a consumption power of a plurality of electric loads, and a motor speed. A first difference value between a motor torque command and the calculated output torque of the motor is calculated. The first difference value is compared with a first reference value. When the first difference value is larger than the first reference value, the hybrid electric vehicle is entered in a fail safe mode.
