Abstract:
To quickly decrease the rotational speed of an engine in a power unit having a flywheel to be connected to or disconnected from an output shaft of the engine.
When decreasing the rotational speed of the engine 12 down to a target rotational speed, the rotational speed of the additional flywheel 42 is acquired. If the rotational speed is equal to or smaller than the target rotational speed of the engine, a clutch 44 is engaged.
