That simulation is absolutely fascinating. I knew hybrid cars were packed with loads of advanced electronic tech, but the use of epicyclic gears as the PSD is pretty cool.
Toyota's HSD system uses such a scheme, but mechanically, Honda's IMA replaces the flywheel with an electric generator/motor, the remainder of the drivetrain being your typical car (they use either a CVT or a manual stick, depending on models and regions). The key then is entirely in the logic driving the electric motor and the VTEC system.
