Abstract
A vehicle driveline system includes a planetary gear arrangement that cooperates with a flywheel member to provide a dual mass variable inertia flywheel assembly. The planetary gear arrangement preferably includes an automated actuator that selectively engages different portions of the planetary gear arrangement to provide at least two operating positions that each have an associated effective mass and a corresponding moment of inertia. Choosing an operating position selectively controls the inertia of the flywheel assembly and greatly reduces or eliminates torsional vibrations that may otherwise occur. The first and second operating positions also provide high and low range transmission operation, respectively.
