Abstract
An infinitely variable transmission (IVT) includes a double planetary gearset with first, second, and third transmission components. The IVT includes a single planetary gearset with fourth, fifth, and sixth transmission components. In one mode, a first set of clutches is engaged, allowing transmission of engine power to the first transmission component, and allowing transmission of IVP power between a second IVP machine and the second transmission component. The third transmission component combines the engine power and the IVP power into first combined power that is transmitted from the third transmission component to the fourth transmission component. The fifth transmission component transmits return power to an engine shaft, and the sixth transmission component combines the first combined power and the return power into second combined power that is output to an output shaft for rotating the output shaft at a range of rotational speeds.
