PROBLEM TO BE SOLVED: To obtain a power for driving auxiliary machinery coupled with the output shaft of a prime mover even during stoppage of operation. 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 crankshaft 56B of engine 50 is coupled, directly or through a belt 102, with auxiliary machinery, e.g. a cooling pump 104, a P/S pump 106, etc., being driven through rotation of the crankshaft 56. When the operation of engine 50 is stopped and and the drive shaft 22 is driven through the assist motor 40 using power stored in a battery 94, a rotary torque TST is applied to the crankshaft 56 from the clutch motor 30 such that the crankshaft 56 rotates at a predetermined r.p.m. Consequently, the crankshaft 56 is rotated to produce a power for driving the auxiliary machinery. |
