PROBLEM TO BE SOLVED: To transmit the pulsating components of power generated from a prime mover, producing a rotary power from a pulsating output, while reducing through a power transmission to an output shaft. SOLUTION: A power transmission 20 coupled with the crankshaft 56 of an engine 50 is provided with a clutch motor 30 and an assist motor 40 and controlled through a controller 80. The engine 50 is subjected to feedback r.p.m. control by the torque of clutch motor 30 such that the engine 50 is operated stably at target torque and r.p.m. The engine 50 is not controlled in the dead band, i.e., the range where the r.p.m. is fluctuated (rotational fluctuation, pulsation of torque) by the pulsating output of engine 50 during steady operation or the range where the r.p.m. of engine 50 is within a threshold value Nref2 from the target r.p.m. Since a dead band is provided, rotational fluctuation (pulsation of torque) is not transmitted to the drive shaft 22. |
