PURPOSE:To reduce the vibration of an engine and vehicle by detecting the variation of the generated torque in an internal combustion engine and controlling the torque which is absorbed or generated, by an electric driving device installed in a main power transmission system, in order to suppress the torque variation. CONSTITUTION:A flywheel motor generator (electric driving device) 5 consisting of a stator coil 5a and a rotor coil 5b is arranged in a main power transmission system set between the engine body 2 of an internal combustion engine 1 and a transmission 4. A microcomputer 6 detects the variation component of the generated torque at each revolution angle of a crankshaft on the basis of the signal of a distributor 3 having a crank angle sensor built in and controls the magnitude of the torque which is absorbed as power generator or generated as electric motor by the electric driving device 5 so that the torque variation which the engine body 2 generates through a torque control part 7 reduces. Therefore, the vibration of the engine and vehicle can be reduced.
