Abstract
A propulsion system for a vehicle designed for reduced torsional vibration of an engine as well as lighter weight of the system. The propulsion system includes a first flywheel mounted on a crankshaft of an engine at an output end of the crankshaft, the engine being disposed in the vehicle, and a motor disposed on the first flywheel on the output side thereof. The motor has a dual function of driving and electric power generation. Further, a second flywheel is disposed on the motor on the output side thereof, and a transmission is disposed in communication with the output side of the second flywheel through a clutch. The first flywheel has an inertial moment which is greater than that of the second flywheel.
