ABSTRACT:
A torque controlling apparatus for an internal combustion engine comprises an electric machinery for absorbing torque from the internal combustion engine and/or for imparting torque to the internal combustion engine; a memory unit for storing, in advance, waveform characteristics of torque deviation generated by the engine in the respective operative conditions of the engine; a detector for detecting an operative condition of the engine; and a control unit. The control unit reads out the waveform characteristics of torque deviation, from the memory unit, corresponding to the detected operative conditions of the engine detected by the detector. The control unit controls the electric machinery to generate countertorque on the basis of the read-out waveform characteristics to cancel the torque deviation.
