Abstract:
1. An apparatus for controlling command torques in a hybrid electric vehicle, the apparatus comprising: an accelerator position sensor for sensing a position of an accelerator and outputting the sensed result as a signal; a speed sensor for sensing a speed of the hybrid electric vehicle and outputting the sensed result as a signal; a shift position sensor for sensing a position of a speed change gear and outputting the sensed result as a signal; a hybrid control unit for, when first level monitoring is initiated, diagnosing the signals received from the accelerator position sensor, speed sensor and shift position sensor, restricting and outputting output values of the signals when the diagnosed signals are abnormal, setting a driver demand torque, setting operating points such as an engine demand torque, an engine rpm (revolution per minute), a generator demand torque, a generator rpm, a driving motor demand torque, a driving motor rpm and so on, restricting outputs to respective restriction values when the respective demand torques and rpms are not within the restriction values, and outputting the respective demand torques and rpms; and a driver for driving an engine, a generator and a driving motor.
