. . . The multifunction gearset incorporates two sets of planetary gears: a power-split planetary gearset and a speed reduction planetary gearset. Both gearsets share the same ring gear, which drives the transaxle’s counter gear. The sun gear of the power-split gearset is connected to the 42 kW motor generator 1 (MG1); the planet carrier is connected to the engine. In the speed reduction planetary gear set, the sun gear is connected to MG2, the carrier is fixed, and the ring gear connects to the counter gear. A parking pawl is also part of the assembly, which is connected to a differential with a final drive ration of 3.267:1.
