ABSTRACT:
For example, while the state of combustion of an internal combustion engine is detected from a cylinder pressure at the top dead center of the cylinders, if a decision has been made that the detected combustion state is an irregular combustion state, on the basis of a result of comparison between a torque waveform corresponding to the irregular combustion state and a torque waveform under normal combustion state, this torque control apparatus for internal combustion engines according to this invention puts into operation a torque correcting device, such as a motor-generator, mounted fixedly to the internal combustion engine, thereby making the former torque waveform approach the latter torque waveform. Therefore, even when an irregular combustion occurs in the internal combustion engine, the torque waveform is substantially free from irregularity, so that vibration and an abnormal noise can be prevented.
