ABSTRACT:
An apparatus and method for controlling command torques in a hybrid electric vehicle, in which information on the command torques maintains an appropriate range by dividing the function of a hybrid control unit (HCU) into first and second levels. A function is included for setting operating points of the HCU itself at the first level and for monitoring torques of the first level at the second level. Whether or not the output command torques are within the restriction values prior to output of the first level is ______ and outputs are restricted to the restriction values when the output command torques exceed the restriction values, thereby preventing a hardware damage in advance. Further a drive demand torque calculated at the second level is compared with a wheel torque of the first level, so that it is possible to determine the suitability of the output command torques.
