ABSTRACT:
A vehicle propulsion system including a split path, electromechanical transmission for use with a flywheel as a power source. One path comprises a mechanical drive train extending between the flywheel power source and the vehicle drive wheels or other power output. The other path comprises an electromechanical drive train of which the mechanical portion is shared with the mechanical drive train by virtue of a common planetary gear arrangement for dividing or combining the power transmitted from or to the flywheel. A battery may be included in the system to make up certain losses from operation and to provide the initial start-up power. A simplified control system is provided to control the transmission of power over the separate parallel paths.
