Abstract
A hybrid vehicle includes a battery system, an internal combustion engine, a first motor/generator, a second motor/generator, and an engageable clutch assembly. The engageable clutch assembly is disposed between the internal combustion engine and the first motor/generator. When engaged, the engageable clutch assembly couples the rotor spindle of the second motor/generator with the hollow rotor shaft of the first motor/generator. The engageable clutch assembly may also operate in a first mechanical mode that selectively engages and disengages the internal combustion engine from the second motor/generator, or operate in a second mechanical mode that dampens shock between the internal combustion engine and the first motor/generator when the international combustion engine operates at a rotational speed that is different than a rotational of the first motor/generator.
